Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may generate a Reed Muller generating matrix for an information bit vector that includes a plurality of information bits. The wireless communication device may remove, from the Reed Muller generating matrix, a row vector consisting of all 1-values to form a modified Reed Muller generating matrix. The wireless communication device may encode the information bit vector using the modified Reed Muller generating matrix to form a codeword. The wireless communication device may transmit the codeword without transmitting a pilot signal or demodulation reference signal for the codeword. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform communications between the UE and a base station based at least in part on a set of semi-persistent resource occasions. The UE may receive a downlink control information releasing the set of semi-persistent resource occasions. The UE may determine a release time to release the set of semi-persistent resource occasions, wherein the release time for releasing the set of semi-persistent resource occasions is with respect to a receive time of the downlink control information. The UE may release the set of semi-persistent resource occasions at the release time based at least in part on the downlink control information.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, control signaling indicating a set of resources of a sidelink channel available for sidelink communication with a second UE. The first UE may receive a sidelink preemption indication indicating that at least a first resource from the set of resources is preempted. The first UE may communicate a sidelink transmission over the sidelink channel with the second UE based on the sidelink preemption indication. In some cases, the first UE may determine whether the SPI satisfies one or more thresholds and the first UE may communicate the sidelink transmission, or refrain from communicating the sidelink transmission, based on determining whether the SPI satisfies the one or more thresholds.

Abstract: Methods, systems, and devices for wireless communications are described that provide improved repetition techniques for autonomous uplink transmissions. Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more time slots in which a first communication on a multi-slot physical uplink control channel (PUCCH) overlaps with a second communication on another PUCCH. The UE may transmit, for each time slot of the one or more time slots, the first communication or the second communication based at least in part on a first priority assigned to the multi-slot PUCCH and a second priority assigned to the other PUCCH. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: One apparatus may be configured to transmit a set of reference signals on shared resources of a first communication link and a second communication link, the set of reference signals indicating an interference channel on the shared resources. The apparatus may further communicate data or control information on the first communication link following transmission of the set of reference signals. Another apparatus may be configured to detect a signal on shared resources of a first communication link and a second communication link, the signal being indicating an interference channel on the shared resources. The other apparatus may further perform channel estimation on the interference channel based on detecting the signal. The other apparatus may further communicate data or control information on the first communication link based on the channel estimation on the interference channel.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a UE. The apparatus may generate a reference signal using a base sequence obtained from a table, the table including a plurality of base sequences that each have a peak-to-average-power ratio (PAPR) metric below a threshold. Then, the apparatus transmits the reference signal to a base station. The reference signal may be multiplexed with a data transmission.
