Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 4-6, 8-13, 17 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Dai in view of US Pat. Pub. 20230113784 to Hyunsu Cha et al. (hereinafter Cha).
Regarding claim 4, Dai in view of Cha teaches The method of claim 1 wherein the conditions or relations or criteria triggering the measurement adaption comprise one or more of:
whether or not, both an Uplink, UL, Reference Signal, RS, and the DL RS configured for performing the bidirectional timing measurement operate in a UE's DL reference cell; (Dai teaches that both an UL RS and DL RS perform the TA and operate in the DL reference cell as illustrated in Fig. 3B above)
and
Dai does NOT teach whether uplink transmission timing changes during a bidirectional timing measurement period due to a UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches whether uplink transmission timing changes during a bidirectional timing measurement period due to a UE autonomous timing adjustment (Cha teaches in para. [0316] a timing advance that changes during measurement due to autonomous timing adjustments during the timing period).
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 5, Dai does NOT teach The method of claim 1 wherein, if both the UL RS and the DL RS configured for performing the bidirectional timing measurement operate in the UE's DL reference cell, then the UE performs or continues performing the bidirectional timing measurement regardless of whether the UE's uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches if both the UL RS and the DL RS configured for performing the bidirectional timing measurement operate in the UE's DL reference cell, then the UE performs or continues performing the bidirectional timing measurement regardless of whether the UE's uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment.(Cha para. [0319] teaches timing advancement with SRS timing measurements that are autonomously changed which causes deterioration of timing measurement accuracy. Cha paras. [0359]-[0361] teach that when a DL reception timing of a UE is changed the UE may autonomously change a UL transmission timing, therefore according to embodiments it is necessary to transmit a TA value that the UE actually used for each UL RS and/or transmission timing information to improve timing measurement accuracy)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 6, Dai does NOT teach The method of claim 1 wherein, if both the UL RS and the DL RS configured for performing the bidirectional timing measurement do not operate in the UE's DL reference cell, then whether the UE performs or continues performing the bidirectional timing measurement depends on whether the UE's uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches if both the UL RS and the DL RS configured for performing the bidirectional timing measurement do not operate in the UE's DL reference cell, then whether the UE performs or continues performing the bidirectional timing measurement depends on whether the UE's uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment. (Cha teaches in para. [0360] “when a specific TRP #1 (and/or cell #1/BS #1) receives SRS resource #0 to calculate/acquire a TOA, and a specific TRP #2 (and/or cell #2/BS) #2) receives SRS resource #1 to calculate/acquire a TOA, an error may occur in a resultant RTOA value obtained through the two TOAs” due to UE autonomous timing adjustment, requiring reporting of “actually used” TA values.)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 8, Dai does NOT teach The method of claim 1 wherein, if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment, discarding, stopping, abandoning, postponing, or restarting the bidirectional timing measurement.
In the analogous art of 3GPP NR wireless communications, Cha teaches if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment, discarding, stopping, abandoning, postponing, or restarting the bidirectional timing measurement. (Cha teaches in para. [0319] teaches that there is a deterioration of timing measurement accuracy due to a change in positioning SRS resource transmission timing due to autonomous TA change in the UE. Cha para. [0320] teaches “changing” the autonomous periodic timing of the transmission by the UE or abandoning the autonomous timing adjustment and using a “used TA value” instead.)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 9, Dai does NOT teach The method of claim 1 further comprising, discarding, stopping, abandoning, postponing, or restarting the bidirectional timing measurement being performed or configured to be performed in a cell in which the SRS is not configured if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches discarding, stopping, abandoning, postponing, or restarting the bidirectional timing measurement being performed or configured to be performed in a cell in which the SRS is not configured if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment. (Cha teaches in para. [0319] teaches that there is a deterioration of timing measurement accuracy due to a change in positioning SRS resource transmission timing due to autonomous TA change in the UE. Cha para. [0320] teaches “changing” the autonomous periodic timing of the transmission by the UE or abandoning the autonomous timing adjustment and using a “used TA value” instead by “the UE using a constant TA window when an SRS resource for UE positioning is transmitted”.)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 10, Dai does NOT teach The method of claim 1 further comprising performing or continuing performing the bidirectional timing measurement in a cell in which the SRS is configured regardless of whether the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches comprising performing or continuing performing the bidirectional timing measurement in a cell in which the SRS is configured regardless of whether the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment. (Cha para. [0316] teaches that continuing timing measurements “regardless of the uplink transmission timing changes” due to autonomous timing adjustments “although the UE has received a TA command from the cell/BS/TRP before transmission time #1 of SRS resource #0, the UE may transmit an SRS using a TA updated/changed at transmission time #2 of SRS resource #0. Additionally/alternatively, for example, the UE may transmit SRS resource #0 by autonomously adjusting/changing the TA minutely to a predetermined level or less before transmission time #3”.)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 11, Dai does NOT teach The method of claim 1 wherein a bidirectional timing measurement requirement for the bidirectional timing measurement performed in a cell in which the SRS is not configured shall not apply if the uplink transmission timing changes during a UE Rx-Tx time difference measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches wherein a bidirectional timing measurement requirement for the bidirectional timing measurement performed in a cell in which the SRS is not configured shall not apply if the uplink transmission timing changes during a UE Rx-Tx time difference measurement period due to the UE autonomous timing adjustment. (Cha para. [0319] teaches that “deterioration of timing measurement accuracy at the BS may occur according to change in a positioning SRS resource transmission timing due to autonomous TA change of the UE.” Cha para. [0371] teaches in Option #1 that “the UE may report nothing to the BS related to a TA or transmission timing”. )
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 12, Dai does NOT teach The method of claim 1 wherein the bidirectional timing measurement requirement for the bidirectional timing measurement performed in a cell in which the SRS is configured shall apply regardless of whether the uplink transmission timing changes during the UE Rx-Tx time difference measurement period due to the UE autonomous timing adjustment.
In the analogous art of 3GPP NR wireless communications, Cha teaches wherein the bidirectional timing measurement requirement for the bidirectional timing measurement performed in a cell in which the SRS is configured shall apply regardless of whether the uplink transmission timing changes during the UE Rx-Tx time difference measurement period due to the UE autonomous timing adjustment. (Cha para. [0319] teaches that “deterioration of timing measurement accuracy at the BS may occur according to change in a positioning SRS resource transmission timing due to autonomous TA change of the UE.” Cha para. [0371] teaches in Option #2 that “the UE may report the fact that the UE has used a configured/indicated TA value without change to the B S/location server/LMF. For example, a 1-bit signal indicating this may be introduced. For example, the 1-bit signal being a first value (0 or 1) may be mapped to the case in which the configured/indicated TA value has been used without change (and/or has been used with change), and the 1-bit signal being a second value (1 or 0) may be mapped to the case in which the configured/indicated TA value has been used with change (and/or has been used without change)”. The indication that it “has been used with change” teaches “regardless of whether the uplink transmission timing changes”.)
It would have been obvious to one of ordinary skill in the art to combine Dai and Cha prior to the effective date of the invention. Each of Dai and Cha are in the field of timing advance and SRS measurements between UE and base station nodes. One of ordinary skill in the art would have been motivated to combine Cha with Dai in order to improve positioning accuracy and timing measurement accuracy as well as miscommunications during transmission timing as taught in Cha paras. [0049]-[0052].
Regarding claim 13, Dai does NOT teach The method of claim 1 wherein if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment, the measurement is restarted.
In the analogous art of 3GPP NR wireless communications, Cha teaches wherein if the uplink transmission timing changes during the bidirectional timing measurement period due to the UE autonomous timing adjustment, the measurement is restarted. (Cha teaches in paras. [0359]-[0361] teaches that the UE may report/transmit a TA value that “the UE has actually used” if the UE autonomously changed the UL transmission timing. Examiner interprets the additional reporting as a “restart” of the measurement since it is a second “update” of a TA.)
