Abstract: A method performed by a first sidelink (SL) user equipment (UE) includes receiving a downlink control information (DCI) from a number of coupled DCIs. The DCI grants reception of a number of scheduled physical SL shared channels (PSSCHs) over an unlicensed SL carrier, and requests a hybrid automatic repeat request (HARQ) response for the scheduled PSSCHs. The method also includes receiving at least one of the PSSCHs from a second SL UE. The method further includes transmitting the HARQ response based on the at least one received PSSCH.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) measures at least a line-of-sight (LOS) path and a non-line-of-sight (NLOS) path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point (TRP), measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival (ToA) of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node to communicate back with the COT initiating IAB node. The sharing of the COT with the parent IAB node and/or child IAB node may also include a sharing of the same COT between a distributed unit and a mobile terminal of the COT-initiating IAB node.

Abstract: Aspects described herein relate to communicating a demodulation reference signal (DMRS) corresponding to a downlink control channel, buffering, based on receiving the DMRS, samples of a downlink data channel associated with the downlink control channel, and processing, during on a time period indicated based at least in part on a sequence of the DMRS, at least a portion of the samples of the downlink data channel. Another aspect relates to determining, based at least in part on a sequence of the DMRS, a time offset from the downlink control channel to a downlink data channel, and determining, based at least in part on the time offset, a time period based on which to transmit or start processing samples of the downlink data channel.

Abstract: Certain aspects may be implemented in a method for wireless communication. The method generally includes determining a counter downlink assignment index (cDAI) to be included in each of a plurality of downlink control information (DCI), each of a first subset of the plurality of DCI being on a control channel, and each of a second subset of the plurality of DCI being on a data channel, each of the first subset of the plurality of DCI scheduling one of the data channels, and wherein each of the control channels and the data channels is on a cell of a plurality of cells, the determination of the cDAIs being based on order of the cell, with respect to the plurality of cells, on which each of the cDAIs is to be transmitted; generating and outputting for transmission the control channels and data channels in accordance with the determination.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating timing resolution limitations due to synchronization signal blocks (SSBs) with low subcarrier spacing (SCS). An example method by a user equipment (UE) generally includes detecting a SSB; determining a start time of a control resource set (CORESET) associated with the detected SSB, wherein the start time of the CORESET is aligned with a boundary of a symbol having a larger cyclic prefix (CP) than one or more other symbols in a same half-subframe; and monitoring the CORESET for a physical downlink control channel (PDCCH) transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a first signal is associated with a New Radio Unlicensed (NR-U) Light configuration; determine a frequency hopping (FH) pattern and a set of FH channels for a second signal based at least in part on the determination that the first signal is associated with the NR-U Light configuration; and receive the second signal based at least in part on the FH pattern and the set of FH channels. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an increased bandwidth configuration for an enhanced physical uplink control channel (ePUCCH) based at least in part on an ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses a plurality of contiguous resource blocks (RBs) for the ePUCCH; and transmit the ePUCCH using the increased bandwidth configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for applying a beam switch interruption time across one or more active component carriers. In some cases a UE may be able to detect an actual overlap condition in which two physical downlink control channels (PDCCHs) monitoring occasions with different beam parameters overlap in time or a soft overlap condition in which a distance between the two PDCCH monitoring occasions in time is less than a threshold value; and to apply a prioritization rule to determine which of the PDCCH monitoring occasions to monitor for PDCCHs in response to detect the actual overlap or a soft overlap (e.g., almost immediately in contact in time or the gap is very small compared to the slot size).

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.
