Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a demodulation reference signal (DMRS) configuration for an uplink message that may indicate for the UE to refrain from including DMRS in at least a first portion of the uplink message based on the DMRS configuration. The UE may encode the uplink message without the DMRS in at least the first portion of the uplink message in accordance with the DMRS configuration. The UE may transmit the uplink message based on encoding the uplink message, and a network entity may receive and decode the uplink message. In some examples, the network entity may receive signaling that includes a set of uplink messages from different UEs. As such, the network entity may decode each, using a respective Reed-Muller (RM) code in accordance with a multi-user decoding algorithm.

Abstract: A sidelink device switches from a first bandwidth part (BWP) for sidelink communication to a second BWP for the sidelink communication and suspends, releases, or continues to use one or more reserved resources in the first BWP based on the switch from the first BWP to the second BWP for the sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a downlink transmission from a network device, the downlink transmission comprising a set of parity bits. The UE may determine, based at least in part on the monitoring, a number of parity checks of the set of parity bits that either failed a parity check procedure or satisfied the parity check procedure. The UE may identify, based at least in part on the monitoring and the number of parity checks, a feedback status indicator for the downlink transmission. The UE may transmit a feedback message that includes the feedback status indicator and additional information based at least in part on the number of parity checks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE in a sidelink communication with the first UE, an indication to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP. The UE may selectively switch from utilizing the first SL-BWP to utilizing the second SL-BWP based at least in part on receiving a positive acknowledgment message from the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure sidelink channel conditions for a group of UEs and transmit a report (e.g., a channel state information (CSI) report) to a base station indicating the sidelink channel conditions. The base station may transmit control information (e.g., group-common downlink control information (GC-DCI)) to the group of UEs triggering the UEs to transmit sidelink reference signals (e.g., CSI reference signals (CSI-RS)) on the sidelink channels so that the UE can measure the sidelink channel conditions and transmit the report. Based on the report, the base station may transmit control information (e.g., a downlink control information (DCI) message) scheduling sidelink communications for the group of UEs. In some examples, the UE may act as a relay node for the group of UEs, and forward control information to the group of UEs.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) receiving a first transmission scheduling resources for a second transmission having a first priority. The UE may determine that one or more symbols of the second transmission are to be unused due to receipt of a cancellation indication or due to identifying a conflict, for example, with higher priority resources. Based on determining that the symbols are to be unused, the UE may determine that the base station will not reschedule the unused resources for another transmission, for example, having the first priority. The UE and the base station may communicate based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described to support codebook construction for enhanced hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may be configured to support a first type of HARQ feedback and a second type of HARQ feedback that includes additional information relative to the first type. A base station may transmit multiple downlink transmissions to the UE, where a first set of the downlink transmissions may be associated with the first type of HARQ feedback and a second set of the downlink transmissions may be associated with the second type of HARQ feedback. The UE may attempt to decode the downlink transmissions and may generate respective feedback for the downlink transmissions. The UE may construct a single HARQ codebook to multiplex the different types of HARQ feedback for the downlink transmissions and may transmit the HARQ codebook to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may allocate a set of information bits into multiple subsets of bits corresponding to channel instances of a channel. The transmitting device may encode a first subset of bits according to a first channel coding scheme for a first channel instance and a second subset of bits according to a second channel coding scheme for a second channel instance. The transmitting device may input encoded subsets of bits to a polarizing transform, which may output a set of encoded polarized bits that are transmitted to a receiving device. Upon reception of the encoded polarized bits, the receiving device may apply a depolarizing transform to obtain multiple subsets of bits corresponding to channel instances of the channel, and may decode each subset of bits according to a respective channel coding scheme.
