Abstract: Aspects presented herein may improve UE positioning by providing enhanced resource patterns that may reduce positioning latency and resource overhead for the UE positioning. In one aspect, a transmitter divides a reference signal associated with UE positioning into a plurality of sub-bandwidths, each of the plurality of sub-bandwidths being associated with a comb offset. The transmitter transmits, to a receiver, the reference signal via the plurality of sub-bandwidths. In another aspect, a receiver receives a configuration to measure a reference signal associated with UE positioning. The receiver receives, from a transmitter, the reference signal via a plurality of sub-bandwidths, each of the plurality of sub-bandwidths being associated with a comb offset.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment (UE) may determine a set of repetitions of a first uplink data channel associated with a first directional beam and a set of repetitions of a second uplink data channel associated with a second directional beam different from the first directional beam. The UE may multiplex an uplink transmission associated with an uplink control channel with one or both of the first uplink data channel and the second uplink data channel, based on the set of repetitions of the first uplink data channel and the set of repetitions of the second uplink data channel As a result, the UE may transmit the multiplexed uplink transmission on one or both of the first uplink data channel and the second uplink data channel.

Abstract: Aspects of the disclosure relate to wireless communication systems that support multi-panel uplink transmissions. Transmission power control (TPC) commands are conveyed in a group common downlink control information (DCI) to support the multi-panel uplink transmissions. Additionally, the DCI can explicitly indicate which uplink panel TPC commands are associated with a particular panel through an explicit panel identification in the DCI, radio resource control (RRC) configuring TPC blocks in a DCI for a particular cell, or by two DCIs in respective search spaces where the TPC in each respective DCI are associated with a corresponding uplink panel transmission.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a network entity, comprising transmitting signaling configuring a user equipment (UE) for physical downlink control channel (PDCCH) repetition based on a set of paired PDCCH monitoring occasions (MOs), transmitting the UE downlink control information (DCI) with an indication of physical downlink control channel (PDCCH) skipping for a skip duration, and processing PDCCH transmissions in accordance with the indication based on one or more rules that account for the PDCCH repetition.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for group-based physical downlink control channel (PDCCH) overbooking and dropping. One aspect provides a method for wireless communications by a user equipment (UE). The method generally includes: determining a total number of slots for physical downlink control channel (PDCCH) monitoring for a slot group is larger than a maximum number of monitored slots for the UE for the slot group; and, in response to the determination that the total number of slots for PDCCH monitoring is larger than the maximum number of monitored slots for the UE for the slot group, dropping a first group of search space (SS) sets, wherein the first group of SS sets is selected based on a priority of the first group of SS sets relative to other groups of SS sets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a dynamic grant for an uplink transmission that overlaps with a configured uplink transmission. The UE may transmit the uplink transmission punctured in the configured uplink transmission based at least in part on receiving the dynamic grant. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a reconfigurable intelligent surface (RIS), a first signal modulated using a first modulation signature, wherein the first modulation signature is an inverted modulation signature associated with a second modulation signature to be applied by the RIS. The first wireless node may receive, from a second wireless node, a second signal indicating that the first signal has been redirected by the RIS and received by the second wireless node. Numerous other aspects are described.

Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.
