in one of M' frequency domain units for sending the one or more measurement pilots [par 0105, to M1 signals in measurement of M signals that are measured according to the M signal measurement pilots, to determine one CQI, where M1 is an integer greater than 1 and less than or equal to M],
and on one of R ports for receiving the measurement pilot signal[par 0378, Optionally, a time interval from a reference resource of measurement by the user equipment according to the second measurement pilot to a reporting moment is X1, where X1 is related to a quantity of resources of the second measurement pilot that are included in one measurement procedure and/or a quantity of ports included in each second measurement pilot],
and R, N’, and M' are all integers greater than or equal to 1[par 0129, 0140, Optionally, the indication unit is further configured to indicate that one measurement process includes M signal measurement pilots and K interference measurement pilots, where M is an integer greater than or equal to 1, K is an integer greater than 1, N is an integer greater than 1, and N1 is an integer greater than or equal to 1 and less than or equal to N];
and sending the feedback information to an access network device [par 0334, 0335, The base station receives a feedback sent by the user equipment. The feedback is generated by the user equipment according to the determined measurement procedure and/or fed-back CSI],
wherein the M’ frequency domain units is determined from M frequency domain units in an (x+1)th time based in channel information sample[par 0132, 0395, 0451, The (n+p)TH moment may represent an (n+p).sup.th subframe or an (n+p)th OFDM symbol or an (n+p)th slot, and n and p are positive integers. An advantage of using a manner of notifying the second measurement pilot by using the first-type DCI lies in that each UE may clearly know information about a second measurement pilot of the UE. Therefore, information (time domain information and frequency domain information) about a channel that the UE needs to measure may be measured in a more precise manner. For example, UE1 knows that UE1 needs to measure channels of only a PRB pair 1 and a PRB pair 2],
the channel information sample comprises channel information in an xth time unit to the (x+T-1)th time unit, both a and T are integers greater than or to 1, M is a positive integer, and M;<M[par 0105, Optionally, the user equipment further includes a fourth determining module, configured to perform synthesis according to M1 signals in measurement of M signals that are measured according to the M signal measurement pilots, to determine one CQI, where M1 is an integer greater than 1 and less than or equal to M]
Lui fail to show time unit to an (x+T-1)" time unit, and both x and T are integers greater than or equal to 1.
In an analogous Jeon show time unit to an (x+T-1)" time unit, and both x and T are integers greater than or equal to 1[par 0136, BS may acquire predicted channel information. The predicted channel information may include channel vectors before the next SRS is received and channel information is updated after the time interval. t0 (for example, in the case of a period of T, before t0+T from t0) The BS may derive predicted channel information (for example, channel vectors and channel parameters) in each time interval between t0 + T-1];
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Liu and Jeon because this can more accurately estimate a channel with low complexity by predicting channel parameters on the basis of an unscented Kalman filter (UKF). [Jeon , par 0011].
21. Liu and Jeon disclose the apparatus according to claim 20, wherein the measurement pilot signal comprises a plurality of groups of elements[par 0707, The example shown in FIG. 16 is used. The set that includes the N reference signal resources includes four resource elements REs. Two ports, for example, the port 0 and the port 1],
LIU fail to show each group of elements comprises more than one element, and the feedback information indicates amplitude information and phase information of each group of elements.
In an analogous art Jeon show each group of elements comprises more than one element, and the feedback information indicates amplitude information and phase information of each group of elements[par 0202, the BS may perform channel estimation on the basis of Type II codebook-based PMI feedback in NR Release 15 instead of using a separate codebook structure. The Type II codebook-based PMI feedback may include amplitude and phase information. The BS may update state information including amplitude information and phase information].
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Liu and Jeon because this can more accurately estimate a channel with low complexity by predicting channel parameters on the basis of an unscented Kalman filter (UKF). [Jeon , par 0011].
22. LIU teaches the apparatus according to claim 20, wherein the operations further comprise: receiving first indication information and second indication information from the access network device[LIU par 0168, 0203, 0208, Optionally, the configuration information includes first indication information and second indication information, the first indication information is information that is obtained by the user equipment by using higher layer signaling, the first indication information is used to indicate the X1 ports multiplexed for the N1 reference signal resources in the set of the N reference signal resources. the base station sends, to the user equipment, configuration information, where the configuration information is used to indicate that M1 ports of the X1 ports are configured to send a first reference signal used to perform channel measurement],
wherein the first indication information indicates location information of the M' frequency domain units for sending the one or more measurement pilots[par 0228, the user equipment determines, according to locations of time-frequency resources of the set that includes the N reference signal resources and the M1 ports of the X1 ports, locations of time-frequency resources of the N2 reference signal resources in the set that includes the N reference signal resources],
and the second indication information indicates a value of N'[par 0203, the base station sends, to the user equipment, higher layer signaling used to indicate configuration information of the N1 reference signal resources in the set that includes the N reference signal resources];
and the receiving a measurement pilot signal comprises: receiving the measurement pilot signal on N' ports in each of the M' frequency domain units[par 0441, the base station configures the second measurement pilot, the base station needs to notify the user equipment of a pattern pattern of the second measurement pilot, port information of the second measurement pilot, a location of a PRB pair of a frequency domain at which the second measurement pilot is located, and a location of a time domain of the second measurement pilot by using the first-type DCI].
Response to Arguments
Chen fails to disclose the above quoted features of claims 1 and 12, and hence Chen does not anticipate claims 1 and 12.
Thus, Chen at least fails to disclose “obtaining a channel information sample, wherein the channel information sample comprises channel information in an x" time unit to an (x+T-1)" time unit, and both x and T are integers greater than or equal to 1; determining M' frequency domain units in M frequency domain units in an (x+T)" time unit based on the channel information sample, wherein the M' frequency domain units are used to send one or more measurement pilots for measuring channel state information (CSI), both M' and M are integers greater than or equal to 1, and M'.
Claims 9, 11, 20 and 22 are rejected under 35 U.S.C. § 103 as allegedly being unpatentable over Chen in view of Wu et al. (U.S. Publication No. 2018/0123671). Applicants respectfully traverse the rejection.
Claims 10 and 21 are rejected under 35 U.S.C. § 103 as allegedly being unpatentable over Chen in further view of Wu and in further view of Wu et al. (U.S. Publication No. 2019/0363760). Applicants respectfully traverse the rejection. Wu ‘760 fails to rectify the deficiencies of Chen and Wu ‘671 discussed above with respect to claims 9 and 20. Therefore, claims 9 and 20 and their dependent claims, including claims 10 and 21, are patentable over the alleged combination of Chen, Wu ‘671 and Wu ‘760. Accordingly, Applicants respectfully request that the rejection be withdrawn.
The applicant’s argument is moot in view of newly rejected claims.
