Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support monitoring for intra-slot and intra-slot-group control channel repetitions. The UE may receive a message indicating a respective set of parameters for a first search space set and a second search space set, an indication that the first and second search space sets are linked, and a respective bitmap for each of the search space sets, where the bitmaps include a same quantity of bits. The bitmaps may indicate a quantity of slots and a location of the slots within a group of slots in which a respective search space set exists within the group of slots. As such, the UE may monitor the first and second search space sets based on the respective sets of parameters and the respective bitmaps (e.g., using monitoring occasions associated with each search space set linked based on the bitmaps).

Abstract: Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QoS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.

Abstract: Some aspects described herein relate to transmitting, to a receiving user equipment (UE), an indication of a fixed size transport block size (TBS) used for a sidelink transmission, and transmitting, to the receiving UE and based at least in part on the fixed size TBS, the sidelink transmission over sidelink resources. Other aspects relate to the receiving UE receiving the indication and the sidelink transmission. Additional aspects relate to a base station for configuring the sidelink resources for fixed size TBS.

Abstract: Wireless communication systems and methods related to utilizing two-stage grants for uplink communications with discontinuous reception (DRX) operations are provided. In some aspects, a user equipment (UE) receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator. The UE activates a timer based at least in part on the first value of the UL schedule timing indicator. The UE monitors a downlink control channel based at least in part on the timer. The UE receives, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, at least one configured grant physical uplink shared channel (CG-PUSCH) in a CG-PUSCH occasion associated with the UE. The base station may transmit, and the UE may receive, multi-user downlink feedback information (DFI) addressed to multiple UEs.

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: Methods, systems, and devices for wireless communication are described. In one example, a method for wireless communication at a user equipment (UE) includes identifying that the UE is in carrier aggregation communication with a first cell having a first sub-carrier spacing and a second cell having a second, different sub-carrier spacing. The method may further include monitoring one or more UE-specific search spaces of the first cell for first control information scheduling a first data communication on the first cell and one or more UE-specific search spaces of the first cell or the second cell for second control information scheduling a second data communication on the first cell, and resolving a scheduling order of the first control information scheduling the first data communication and the second control information scheduling the second data communication based at least in part on the monitoring and on a scheduling condition.
