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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 4, 18, 20-21, 23 and 28-30 are rejected under 35 U.S.C. 103 as being unpatentable over Luo et al. (hereinafter Luo) US 2018/0054348 A1.
Regarding Claim 1, Luo teaches an apparatus for wireless communication at a user equipment (UE) (Fig. 3; UE 302), comprising:
a memory (Fig. 14);
and at least one processor coupled to the memory (Fig. 14) and configured to: transmit, to a base station having multiple transmission reception points (TRPs) (¶0079; The functionality of a TRP may be similar in one or more aspects to (or incorporated into) the functionality of…a base transceiver station (BTS), a transceiver function (TF), a radio transceiver), a channel state information (CSI) report based on a set of reference signals, the set of reference signals including a first reference signal associated with a first beam direction and a second reference signal associated with a second beam direction (Fig. 3 & ¶0187; the CSI feedback for a given link may be based on CSI-RS from multiple links. Thus, a UE may send a joint CSI report. ¶0191; a UE may communicate via multiple links where each link is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), etc.);
and switch, for one or more channels, to use the first beam direction with a first TRP of the multiple TRPs based on the set of reference signals before receiving any transmission corresponding to the first beam direction from the base station (¶0196; a device e.g. a UE that is communicating via multiple links performs beam switching for one link independently of the beam switching for any of other links. For example, a UE can send a message on a particular link to inform a TRP that the UE is switching to another beam or direction).
Luo does not expressly teach “…before receiving any transmission…” However, this limitation is obvious in view of Luo’s teachings. This limitation means to one of ordinary skill in the art that the UE to switch to use the first beam direction without waiting for a transmission corresponding to the first beam direction from the base station. Here, Luo teaches “to inform a TRP that the UE is switching to another beam or direction” in ¶0196. This means that the switching for one or more channels take place without waiting for any confirmation from the base station. Luo also is directed to independent links which means that one link can indicate link switching or failure to other links without receiving the indication for the base station. See abstract.
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to reach the claim language and realize the same conclusion from Luo’s teachings using common skills in the art in order to enable a UE to effectively communicate with different TRPs (e.g., gNodeBs or eNodeBs) on different links (¶0004).
Regarding Claims 4, Luo teaches the apparatus of claim 1, the at least one processor being further configured to: switch, for the one or more channels, to use the second beam direction with a second TRP of the multiple TRPs based on the set of reference signals before receiving any transmission corresponding to the second beam direction from the base station (¶0200; obvious because the communication is over multiple links with multiple TRPs).
Regarding Claims 18, Luo teaches the apparatus of claim 1, wherein the CSI report is a multi-beam CSI report for inter-cell multiple transmission/reception point (m-TRP), and the at least one processor is configured to switch to using the first beam direction to receive a first channel based on an association with a physical cell ID (¶0084; this limitation is obvious to one of ordinary skill in the art because Luo’s teachings is not limited to TRP. For example, may options for the TRPs are disclosed in ¶0084; a TRP may refer to a physical entity that incorporates radio head functionality for a particular physical cell. This functionality may be similar in one or more aspects to (or incorporated into) the functionality of a NodeB, an eNodeB, a gNodeB, a radio network controller (RNC), a base station (BS), a radio base station (RBS), a base station controller (BSC), a base transceiver station (BTS), a transceiver function (TF), a radio transceiver, a radio router, a basic service set (BSS), an extended service set (ESS), a macro cell, a macro node, a Home eNB (HeNB), a femto cell, a femto node, a pico node, or some other similar entity. The TRPs 204 and 206 of FIG. 2 may communicate with each other via network entities 216, a direct communication link 218, or some other link).
Regarding Claim 20, Luo teaches the apparatus of claim 1, further comprising at least one antenna and a transceiver coupled to the at least one processor (Fig. 14).
Regarding Claim 21, Luo teaches an apparatus for wireless communication at a base station having multiple transmission reception points (TRPs) (¶0079; functionality of a TRP may be similar to functionality of a transceiver function (TF), a radio transceiver), comprising:
a memory (Fig. 14);
and at least one processor coupled to the memory (Fig. 14) and configured to: receive, from a user equipment (UE), a channel state information (CSI) report based on a set of reference signals, the set of reference signals including a first reference signal associated with a first beam direction and a second reference signal associated with a second beam direction (Fig. 3 & ¶0187; CSI feedback for a given link may be based on CSI-RS from multiple links. Thus, a UE may send a joint CSI report. ¶0191; a UE may communicate via multiple links where each link is associated with a corresponding beam. The UE may communicate with a first TRO via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), etc.);
and switch, for one or more channels, to use the first beam direction with a first TRP of the multiple TRPs before transmitting an indication to switch beams to the UE (obvious from ¶0196; a UE can send a message on a particular link to inform a TRP that the UE is a switching to another beam or direction. The UE can be a device or a base station. This limitation is obvious because the base station switches to use the first bean whenever it is informed by the UE about a beam switch. Moreover, switching to a first beam is not based on received CSI report. Stated differently, Luo teaches “to inform a TRP that the UE is switching to another beam or direction” in ¶0196. This means that the switching for one or more channels take place without waiting for any confirmation from the base station or vice versa. Luo also is directed to independent links which means that one link can indicate link switching or failure to other links without receiving the indication for the base station or vice versa. See abstract.
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to reach the claim language and realize the same conclusion from Luo’s teachings using common skills in the art in order to enable a UE to effectively communicate with different TRPs (e.g., gNodeBs or eNodeBs) on different links (¶0004).

Regarding Claim 2, Luo teaches the apparatus of claim 1, but does not expressly teach wherein the at least one processor is configured to switch to use the first beam direction with the first TRP based on the set of reference signals before receiving a downlink control information (DCI) that indicates an update to a transmission configuration indicator (TCI) state.
Kwon teaches wherein the at least one processor is configured to switch to use the first beam direction with the first TRP based on the set of reference signals before receiving a downlink control information (DCI) that indicates an update to a transmission configuration indicator (TCI) state (Fig. 5, ¶0113 & ¶0116; operating in a QCL environment after beam failure recovery but prior to TCI states related to spatial QCL purposes updates are complete are provided. Utilizing QCL information after beam failure recovery but before TCI states related to spatial QCL purposes are updated may lead to degraded performance due to outdated or incorrect QCL information. See also Fig. 5 operations 500 for more details).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed limitation to incorporate the teachings of Kwon into the system of Luo in order to operating in a QCL environment after beam failure (¶0113). Utilizing QCL information after beam failure recovery but before TCI states related to spatial QCL purposes are updated may lead to degraded performance due to outdated or incorrect QCL information. Id.
Regarding Claim 3, Luo teaches the apparatus of claim 1, but does not expressly teach wherein the at least one processor is configured to switch to use the first beam direction with the first TRP based on the set of reference signals before receiving an activation of a transmission configuration indicator (TCI) state from the base station.
Kwon teaches wherein the at least one processor is configured to switch to use the first beam direction with the first TRP based on the set of reference signals before receiving an activation of a transmission configuration indicator (TCI) state from the base station (Fig. 5, ¶0113 & ¶0116; operating in a QCL environment after beam failure recovery but prior to TCI states related to spatial QCL purposes updates are complete are provided. Utilizing QCL information after beam failure recovery but before TCI states related to spatial QCL purposes are updated may lead to degraded performance due to outdated or incorrect QCL information. See also Fig. 5 operations 500 for more details).

Regarding Claim 5, Luo teaches the apparatus of claim 4, but does not expressly teach wherein the first reference signal and the second reference signal have a quasi co-location (QCL) type D relationship with a pair of transmission configuration indicator (TCI) states or with a single TCI state that includes a parameter to indicate multiple beams.
NPL teaches wherein the first reference signal and the second reference signal have a quasi co-location (QCL) type D relationship with a pair of transmission configuration indicator (TCI) states or with a single TCI state that includes a parameter to indicate multiple beams (NPL define QCL Type D relationships for multi-TRPs, see introduction & proposal 3 for QCL-typeD configuration).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed limitation to incorporate the teachings of NPL into the system of Luo in order to evaluate and if needed specify beam management related enhancements for simultaneous multi-TRP transmission with multi-panel reception (1. Introduction, first 3 lines).
Regarding Claim 6, Luo in view of NPL teaches the apparatus of claim 5, NPL further teaches the at least one processor being further configured to: transmit or receive a control channel, in a single downlink control information (sDCI) operation with the multiple TRPs, based on the first beam direction (obvious from proposal 7 because gNB response of the TRP can be the DCI format).
Regarding Claim 10, Luo in view of NPL teaches the apparatus of claim 5, NPL further teaches wherein for a multiple downlink control information (mDCI) configuration for communication with the multiple TRPs, the at least one processor is further configured to: transmit or receive a first transmission of the one or more channels associated with a first control resource set (CORESET) based on the first beam direction (obvious, see proposal 8); and transmit or receive a repetition of the one or more channels associated with a second CORESET based on the second beam direction (obvious, see proposals 8-9).

Thus, a UE may send a joint CSI report. This joint report may be sent on one or more of the links. When transmitting the feedback, the transmitter may provide information on how it uses the CSI-RS from multiple links. See also multi link beam switching in ¶0194-¶201).

Claims 24 and 26-27 are substantially similar to claims above, thus the same rationale applies.
Claims 7-9, 11-12 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Luo in view of NPL and further in view of Ly et al. (hereinafter Ly) US 2020/0045737 A1.

Luo in view of NPL do not expressly teach “the repetition are frequency division multiplexed (FDM) or spatial division multiplexed (SDM)”
Ly teaches the repetition are frequency division multiplexed (FDM) or spatial division multiplexed (SDM) (¶0083; using time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed limitation to incorporate the teachings of Ly into the system of Luo in view of NPL in order to maximize network capacity by enabling simultaneous data transmission (known in the art).
