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.
Claims 1-8, 13-23 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Khoshnevisan et al (US 2023/0318768, hereinafter Khoshnevisan) and in view of John Wilson et al (US 2018/0278467, hereinafter Wilson).
Regarding claim 1, Khoshnevisan discloses a network node (network entity, Para [0018]) in communication with a wireless device, the network node comprising: processing circuitry (processor, Para [0018]) configured to: cause transmission of a configuration to a wireless device for sounding reference signal, SRS, transmission over a plurality of symbols in one or more slots (UE receives SRS configuration from network entity, Para [0091], SRS configures multiple SRS Tx occasions, which correspond to symbols within a slot or symbols across multiple slots, Para [0110]), the configuration indicating: a SRS resource set including at least one SRS resource (the network configure the UE with SRS resources and resource sets identifying resources and parameters to be used for SRS transmissions, Para [0094]); and temporal hopping of the SRS transmission over the plurality of symbols (SRS configuration indicates a hopping pattern for SRS transmissions across multiple SRS transmission occasions, and a comb offset hopping configuration, Para [0092]); receive the SRS transmission according to the configuration (receiving SRS across the SRS Tx occasions according to the configuration, Para [0017]); but does not explicitly disclose perform SRS measurements based on the received SRS transmission. Wilson discloses the base station can monitor the SRS transmission and perform SRS measurements on the received SRS transmissions, Para [0080].

Regarding claims 4 and 16, Khoshnevisan discloses the network node/device of claim 2/14, wherein the configured hopping pattern is defined by a hopping offset applied at each hop to a set of initial at least one of cyclic shifts and comb offsets configured for the plurality of SRS ports. (hopping pattern includes a different comb offset applied for each SRS transmission occasion, Para [0007], all ports may be configured on the same REs/comb offset, Para [0100]).
Regarding claims 5 and 17, Khoshnevisan discloses the network node/device of claim 4/16, wherein the hopping offset is a function of at least one of a symbol index and a slot index (SRS comb offset hopping formula is a function of time (e.g. slot number, symbol number), Para [0109]).
Regarding claims 6 and 18, Khoshnevisan discloses the network node/device of claim 2/14, wherein the configured hopping pattern is applied within each of the one or more slots, wherein the hopping is performed per symbol or per every integer number of symbols (SRS configuration indicates a hopping pattern for SRS transmissions across multiple SRS transmission occasions, Para [0092], SRS configures multiple SRS Tx occasions, which correspond to symbols within a slot or symbols across multiple slots, Para [0110]).
Regarding claims 7 and 19, Khoshnevisan discloses the network node/device of claim 2/14, wherein the configured hopping pattern is applied per slot, wherein the hopping is performed from slot to slot (SRS configuration indicates a hopping pattern for SRS transmissions across multiple SRS transmission occasions, Para [0092], SRS configures multiple SRS Tx occasions, which correspond to symbols across multiple slots, Para [0110]).
Regarding claims 8 and 20, Khoshnevisan discloses the network node/device of claim 2/14, wherein the configured hopping pattern is applied over the plurality of symbols in the one or more slots, wherein the hopping is performed per symbol or every integer number of symbols across the one or more slots (SRS configuration indicates a hopping pattern for SRS transmissions across multiple SRS transmission occasions, Para [0092], SRS configures multiple SRS Tx occasions, which correspond to symbols within a slot or symbols across multiple slots, Para [0110]).
Regarding claim 13, Khoshnevisan discloses a wireless device in communication with a network node, the wireless device comprising: processing circuitry configured to: receive a configuration for sounding reference signal, SRS, transmission over a plurality of symbols in one or more slots (UE receives SRS configuration from network entity, Para [0091], SRS configures multiple SRS Tx occasions, which correspond to symbols within a slot or symbols across multiple slots, Para [0110]), the configuration indicating: a SRS resource set including at least one SRS resource (the network configure the UE with SRS resources and resource sets identifying resources and parameters to be used for SRS transmissions, Para [0094]); and temporal hopping of the SRS transmission over the plurality of symbols (SRS configuration indicates a hopping pattern for SRS transmissions across multiple SRS transmission occasions, and a comb offset hopping configuration, Para [0092]); and perform SRS transmission according to the configuration (transmitting the SRS across the SRS Tx occasions according to the configuration, Para [0017]).
