Abstract: Certain aspects of the present disclosure provide techniques for transmitting demodulation reference signals (DMRS) with control channels (e.g., physical downlink control channels (PDCCHs)) that enable receiving devices to bundle (e.g., coherently combine) the DMRS over time. A UE may detect a portion of a PDCCH to the UE in at least one resource element group (REG), wherein the REG is in a segment of a control resource set (CORESET) configured for the UE or a group of UEs including the UE and the REG is during a first search space (SS) set occasion configured for the UE or the group of UEs; and process wideband (WB) DMRS in the segment during the first SS set occasion and in the segment during at least one second SS set occasion, wherein the UE does not detect another portion of the PDCCH or another PDCCH during the second SS set occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

Abstract: A user equipment (UE) can report direct current (DC) subcarrier location information for a subset of possible combinations of bandwidth parts and component carriers supported by a base station. In one aspect, the UE can receive, from a scheduling entity, a message for activating a first combination of bandwidth parts (BWPs) and component carriers (CCs) in a list including a subset of combinations of BWPs and CCs configured for the UE. The UE can report direct current subcarrier location information for the first combination of BWPs and CCs to the scheduling entity.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a reduced-capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.

Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a wakeup signal (WUS) monitoring configuration that identifies one or more first WUS monitoring parameters associated with short discontinuous reception (DRX) cycle operation of the UE and one or more second WUS monitoring parameters associated with long DRX cycle operation of the UE. The UE may monitor for a WUS based at least in part on the WUS monitoring configuration. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure relate to a technique for multiplexing downlink control information (DCI) signals for multiple user equipments (UEs) at an aggregation level (AL) by coding the DCI signals together in a control channel and transmitting the control channel. In an exemplary method, a BS multiplexes a first plurality of downlink control information (DCI) signals for a first plurality of user equipments (UEs) at a first aggregation level (AL) coded together in a first control channel and transmits the control channel.
