Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure a user equipment (UE) with a low latency mode indication that indicates one or more different retransmission timelines or repetition techniques relative to communications that are not associated with the low latency mode indication. The base station may provide the low latency mode indication in downlink control information (DCI) that may include a resource grant for uplink resources for an uplink communication, such as for a UE transmission of pose information of an extended reality (XR) application. The low latency mode indication may signal that no retransmissions of the uplink communication are to be transmitted, that a different retransmission timeline is enabled for low latency mode communications, that retransmissions may happen based on a particular timeline that is determined according to one or more timers, or any combinations thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may receive a measurement reference channel configuration from a source relay. The UE may transmit a reference channel based at least in part on the measurement reference channel configuration. The UE may receive, from the source relay, a command for the remote UE to switch from the source relay to a target relay based at least in part on a measurement of the reference channel transmitted from the remote UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may support communication of a compressed channel state information (CSI) feedback. The UE and the network entity may use closed-loop feedback to improve beamforming tracking accuracy. For example, the UE may receive a CSI reference signal (CSI-RS) that is beamformed based on a channel estimate of a sounding reference signal (SRS) or a previous CSI feedback, or both. The UE may transmit a feedback message including compressed CSI that is generated through encoding a measurement of the CSI-RS. The compressed CSI may be generated based on a predicted channel estimate at the network entity, determined based on the channel estimate of the SRS or the previous CSI feedback.

Abstract: Wireless communications systems and methods related to hybrid automatic repeat request (HARQ) history feedbacks are provided. A user equipment (UE) receives one or more data blocks associated with a plurality of hybrid automatic repeat request (HARQ) processes. The UE may transmit an individual feedback for each of the one or more data blocks indicating whether the data block is received successfully. The UE may transmit a feedback history report for a set of HARQ processes less than all of the plurality of HARQ processes.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a set of communication links, where at least one communication link of the set includes a sidelink. The UE may transmit a report based on an event associated with the sidelink that triggers the power headroom report. Additionally or alternatively, the UE may identify a carrier aggregation configuration for a set of communication links where at least one communication link of the set is a sidelink. The UE may determine an event associated with the sidelink that triggers a power headroom report, and transmit the power headroom report based on the determined event associated with the sidelink that triggers the power headroom report.

Abstract: Methods, systems, and devices for wireless communications are described for configuring discontinuous reception (DRX) cycles within a DRX time period at a user equipment (UE). DRX configurations may provide that different DRX cycles have non-uniform cycle durations within the DRX time period. Such non-uniform cycle durations may provide DRX ON-durations that are aligned with a periodicity of downlink traffic to the UE in which the downlink traffic may be unaligned with timing boundaries used for wireless communications between the UE and a base station, such as slot boundaries or symbol boundaries.

Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

Abstract: A non-coherent communication system in which a transmitting device does not transmit a pilot/DMRS, such that the receiving device may be configured to determine or decode the information received from the transmitting device without performing any channel estimation. An apparatus for wireless communication at a receiving device receives, from a transmitting device, a non-coherent signal having data. The apparatus may determine data from the received signal without performing a channel estimation. In another aspect, an apparatus at a transmitting device divides an information payload including a set of bits into multiple subsets of bits, maps each of the multiple subsets of bits into a respective sequence of complex symbols, generates a non-coherent transmission signal based on the respective sequences, and transmits the non-coherent transmission signal to a receiving device.
