Abstract: Certain aspects of the present disclosure provide techniques for replacing and/or fixing broken uplink repetitions due to segmentation of nominal repetitions into actual repetitions. A method that may be performed by a user equipment (UE) includes detecting that a configured repetition pattern for uplink transmission to a network entity results in segmentation of at least one nominal repetition into multiple actual repetitions, modifying the configured repetition pattern, based at least in part on the detection, to avoid segmentation of nominal repetitions into multiple actual repetitions, and sending the uplink transmission to the network entity in accordance with the modified repetition pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate with one or more second UEs to identify a resource overlap for a resource for relay communication. The first UE may selectively transmit using the resource with the resource overlap in accordance with a random access procedure. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adaptively choose a resource selection scheme between a sensed selection scheme and a random selection scheme to determine a sidelink resource. The UE may transmit a sidelink communication utilizing the sidelink resource based at least in part on adaptively choosing the resource selection scheme. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving one or more downlink transmissions from a base station, and transmitting, based on comparing one or more parameter values of the one or more downlink transmissions to one or more threshold values, a sounding reference signal (SRS) to the base station over uplink resources. Other aspects relate to receiving, from a user equipment (UE), feedback related to decoding one or more downlink transmissions, wherein the feedback includes an indication that the UE is transmitting a SRS, and receiving, based on the indication, the SRS from the UE over uplink resources.

Abstract: An acknowledgment (ACK)/negative-ACK (NACK)-based relaying scheme for uplink coverage improvement is provided. A relay station receives, from a destination device, a first feedback transmission associated with the first data transmission. The relay station determines whether the destination device successfully receives the first data transmission based on the first feedback transmission. The relay station communicates, with the destination device, a second feedback transmission associated with the first data transmission when the destination device does not successfully receive the first data transmission. The relay station communicates, with the destination device, a second data transmission associated with the second feedback transmission, in which the second data transmission comprises at least a portion of the first data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer or counter in connection with failing to transmit a feedback message at a time for which the feedback message is scheduled for transmission. The UE may defer transmission of the feedback message for one or more attempts at transmitting the feedback message. The UE may perform one of: transmitting the feedback message before expiration of the timer or before the counter satisfying a count threshold, or discarding the feedback message after expiration of the timer or in connection with the counter satisfying the count threshold. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating signaling of PUCCH and PUSCH simultaneous transmission or multiplexing are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, an overlapping uplink transmission configuration. The example method also includes detecting an occurrence of an overlapping uplink transmission comprising at least a portion of uplink control information and at least a portion of uplink data overlapping in a time domain. Additionally, the example method includes transmitting at least one of the uplink control information or the uplink data based on the overlapping uplink transmission configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select a precoding matrix of orthogonal beams. The base station may precode a channel state information reference signal (CSI-RS) transmitted to a user equipment (UE) using the precoding matrix of orthogonal beams. The base station may receive, from the UE, one or more reports that indicate one or more beam indices selected from beam indices associated with the precoding matrix of orthogonal beams. Numerous other aspects are provided.

Abstract: The apparatus of wireless communication is a UE and a base station. The UE received a control information indicating a reference signal (RS) mode for a non-coherent transmission of an UCI to the base station. The UE in the RS mode may map an RS according to an RS pattern and the UCI into resource elements assigned for a PUCCH to transmit the UCI and transmit an uplink control signal including the RS and the UCI to the base station over the PUCCH. The UE may determine a RS pattern and puncture the resource elements mapped with the code point of the UCI that corresponds to the RS pattern and map the RS based on the RS pattern. The UE may map the RS based on the RS pattern and map the code point by rate matching around the resource into which the RS is mapped.
