A method performed by a user equipment (UE) includes receiving a configuration about a channel state information (CSI) report and determining, based on the configuration, the CSI report including a precoding matrix indicator (PMI) and X channel quality indicators (CQIs). The configuration includes a value of N4 and a codebookType set to typeII-Doppler-r18. The PMI includes a first indicator indicating Q Doppler domain (DD) vectors, each of length N4, where X∈{1,2}. The method further includes partitioning the CSI report into CSI part 1 and CSI part 2; partitioning the CSI part 2 further into groups G0, G1, and G2; and transmitting the CSI part 1 and at least a portion of the CSI part 2. The portion of the CSI part 2 is determined based on a priority value and corresponds to G0, (G0, G1), or (G0, G1, G2).

Abstract: Apparatuses and methods for SRS enhancement for interference randomization in wireless networks. A method performed by a user equipment (UE) includes receiving a configuration about a sounding reference signal (SRS) resource. The configuration includes information about a cyclic shift offsetϵ{0,1, . . . , nSRSCS,max−1} and a transmission-comb offsetϵ{0,1, . . . , KTC−1}. nSRSCS,max is a maximum number of cyclic shifts and KTC is a transmission comb number. The SRS resource is associated with a plurality of antenna ports. The method further includes determining, based on a first pseudo-random sequence, the cyclic shift offset for each of the plurality of antenna ports; determining, based on a second pseudo-random sequence, the transmission-comb offset for each of the plurality of antenna ports; and transmitting, based on the cyclic shift offset and the transmission-comb offset, the SRS resource.

Abstract: A base station (BS) and user equipment (UE) are configured to perform measurement/reporting and spectrum coordination request/response in wireless networks. A method for operating a UE includes receiving configuration information for measuring interference from a neighboring cell, measuring the interference from the neighboring cell based on the configuration information, and computing a change in the measured interference from the neighboring cell based on a current measured interference level and a previous measured interference level. The method further includes determining, based on at least in part a determination that the change in the measured interference exceeds a first threshold, whether to generate a measurement report and transmitting the measurement report on an uplink channel.

Abstract: Directional sensing capability, including number of beams, beam-width, analog or digital beam sweeping, and supported waveforms, may be indicated by a user equipment (UE), which may then receive a configuration for directional sensing including number of beams, maximum or minimum beam-width, reception time between transmission beam sweeping, and waveform. The UE then performs directional sensing based on the received configuration. The configuration for directional sensing may be for one of monostatic sensing with reception periods between consecutive sensing signal transmissions or bistatic sensing using a plurality of beams. The UE's directional sensing capability may include capability of spatial multiplexing of sensing signals with communication signals. The configuration for directional sensing may permit spatial multiplexing of sensing signals with communication signals. The UE may determine to perform spatial multiplexing of sensing signals with communication signals based on orthogonality of a desired sensing beam with a beam for communications.
