Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message indicating that a control resource set for a downlink control channel is associated with a plurality of demodulation reference signal (DMRS) ports. The UE may determine, based at least in part on the configuration message, that a first set of DMRS resource elements in a first symbol of the control resource set correspond to a first DMRS port of the plurality of DMRS ports and a second set of DMRS resource elements in a second symbol of the control resource set correspond to a second DMRS port of the plurality of DMRS ports. The UE may decode the downlink control channel based at least in part on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: Wireless communications systems and methods related to providing subchannel selection or recommendation and/or channel state information (CSI) for sidelink communications (e.g., operating in mode-1 radio resource allocation (RRA) via a buffer status report (BSR) are provided. A first user equipment (UE) transmits, to a base station (BS), a BSR indicating subchannel information associated with one or more UEs. The UE receives, from the BS in response to the BSR report, a grant for transmitting a first sidelink transmission to a second UE of the one or more UEs. The UE transmits, to the second UE based on the grant, the first sidelink transmission.

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: Aspects described herein relate to transmitting or receiving a demodulation reference signal (DMRS) for an antenna port over a set of multiple DMRS frequency tones in a symbol of a slot based on a DMRS configuration, and transmitting or receiving a phase tracking reference signal (PTRS) for the antenna port over a cluster of multiple PTRS frequency tones in the symbol or a different symbol of the slot, wherein the cluster of multiple PTRS frequency tones are adjacent to one another in frequency, and wherein at least one PTRS frequency tone in the cluster of multiple PTRS frequency tones is a non-zero power (NZP) PTRS frequency tone that overlaps, in frequency, at least one DMRS frequency tone in the set of DMRS frequency tones.

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.
