Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may receive a signal in an automatic gain control resource and may receive a physical sidelink feedback channel message based on a gain for reception of the first physical sidelink feedback channel message, where the gain is based on receiving the signal. In some aspects, the first physical sidelink feedback channel message may be one of a set of physical sidelink feedback channel messages time-division multiplexed over a set of contiguous time resources. Additionally, or alternatively, the user equipment may receive a sidelink message after receiving the physical sidelink feedback channel message using a second gain, where the second gain is based on receiving a second signal in a second automatic gain control resource that occurs before the first automatic gain control resource.

Abstract: Systems and techniques are provided for wireless communications. A process can include receiving a configured shared demodulation reference signal (DMRS) and determining, based on the configured shared DMRS, blind channel estimation information. The process can include receiving, based on the blind channel estimation information, control information indicative of a scheduled downlink data transmission. The process can include receiving, based on the blind channel estimation information, the scheduled downlink data transmission, wherein the scheduled downlink data transmission is received based on the control information and using the blind channel estimation information corresponding to the configured shared DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a spatial division multiplexing configuration associated with a physical uplink shared channel (PUSCH) having a first set of transmission layers corresponding to a first sounding reference signal (SRS) resource set and a second set of transmission layers corresponding to a second SRS resource set. The UE may transmit a PUSCH communication that includes the first and second sets of transmission layers based at least in part on a port mapping that indicates a first association between a first subset of demodulation reference signal (DMRS) ports of a set of DMRS ports and the first set of transmission layers, and a second association between a second subset of DMRS ports and the second set of transmission layers. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A segment based feedback codebook may lead to more efficient and responsive codebook generation for hybrid automatic-repeat/request (HARQ) acknowledgment reporting. A segment-based feedback codebook may support codebook generation where each bit in an acknowledgment/negative-acknowledgment (ACK/NACK) codebook may correspond to a segment of resources. A network entity may schedule a user equipment with one or more messages within one or more segments. The UE may generate one ACK/NACK bit for each segment, and a HARQ codebook transmitted in a physical uplink control channel reporting occasion may include the ACK/NACK bits corresponding to the messages in those segments. A segment may be a set of time domain resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating a coding rate value corresponding to a downlink control information (DCI) format. The coding rate value may indicate a coding rate of the DCI format. The UE may receive, via a quantity of resource elements (REs) that is based on a payload size and the coding rate value, a DCI message of the DCI format that includes scheduling information associated with a data message, and the UE may receive the data message in accordance with the scheduling information. In some examples, the UE may receive the DCI message via a physical downlink control channel (PDCCH) multiplexed with a physical downlink shared channel (PDSCH) that carries the data message.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multi-bit feedback via a sidelink feedback channel. In some aspects, a first user equipment (UE) and a second UE may support a physical sidelink feedback channel (PSFCH) design that is capable of conveying multi-bit feedback across multiple resource blocks. For example, the first UE may monitor for one or more sidelink data messages from the second UE and may transmit, to the second UE over multiple resource blocks of a PSFCH, a feedback message indicating multiple feedback bits associated with the sidelink data messages. The first UE may indicate or otherwise convey the multiple feedback bits via various sequence types or coding schemes. Additionally, or alternatively, the first UE and the second UE may support a resource selection scheme involving one or more parameters associated with conveying multi-bit feedback over a PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may monitor a set of physical sidelink shared channel (PSSCH) resources for sidelink messages from a second wireless device. The first wireless device may generate one or more codebooks that include acknowledgement (ACK) or negative acknowledgement (NACK) bits corresponding to the sidelink messages. The first wireless device may transmit one or more feedback messages to the second wireless device on one or more physical sidelink feedback channel (PSFCH) resources in accordance with a sidelink feedback configuration of the first wireless device. The one or more feedback messages may include an indication of the one or more codebooks. The techniques described herein may enable the first wireless device to transmit the one or more feedback messages to the second wireless device with higher throughput and greater signaling efficiency, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive an indication of a configuration for transmitting a propagation delay compensation (PDC) report and a reference signal resource for performing one or more round trip timing (RTT) measurements associated with the PDC report. The UE may receive control signaling from the base station which includes a request for the UE to transmit the PDC report which includes the one or more RTT measurements. The UE may transmit the PDC report based on receiving the request from the base station, and the UE may perform one or more PDC procedures based on transmitting the PDC report. In some other examples, the base station may transmit a request to a higher layer to obtain the RTT measurements, and may relay the RTT measurements to the UE for performing the PDC procedures.
