    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first part of a channel state information (CSI) report, wherein the first part includes an indication of whether a value of a second part of the CSI report matches a value of a previous CSI report; and selectively transmit the second part of the CSI report based at least in part on whether the indication indicates that the value of the second part of the CSI report matches the value of the previous CSI report. In some aspects, a UE may determine a modified subband size of the UE, wherein the modified subband size is different than a configured subband size of the UE; and transmit, in a CSI report, an indication regarding the modified subband size to a base station. Numerous other aspects are provided.

    Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

    IPC: H04L5/00

    Abstract: A user equipment (UE) is transmits capability signaling information to a base station. The capability signaling information may be associated with a capability of the UE to maintain coherence and bundle demodulation reference signals (DM-RS) when a transmission is interrupted. The base station may receive a transmission from the UE having dropped symbols, may determine if the capability signaling information indicates that the UE maintained coherence over the dropped signals, and may utilize bundled DM-RS to decode the transmission if the capability signaling information indicates that the UE maintained coherence.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, on a first downlink receive beam, one or more first positioning reference signals (PRS) transmitted by a first base station on a first downlink transmit beam, attempts to receive, on the first downlink receive beam, one or more second PRS transmitted by a set of base stations, other than the first base station, on a set of downlink transmit beams other than the first downlink transmit beam, determines that one or more signal strength measurements of the one or more second PRS received on the first downlink receive beam are below a threshold, and transmits a request to update the set of downlink transmit beams or the first downlink transmit beam, or to establish a new beam pairing with the first base station, the set of base stations, or both.
