Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive a first reference signal from a second device and may generate a channel status feedback message based on the first reference signal. The first device may bundle the second reference signal and the channel status feedback message and may transmit the second reference signal and the channel status feedback to the second device. The first device may initiate a data transfer with the second device based on transmitting the second reference signal and the channel status feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may be configured to receive a downlink control message (e.g., an uplink grant) that schedules resources for transmitting repetitions of an uplink channel transmission, where each of the repetitions of the uplink channel transmission may correspond to a single transport block. The UE may determine a plurality of sounding reference signal (SRS) resources based on the downlink control message, and transmit different instances of the uplink channel transmission repetitions according to different SRS resources. The described examples for uplink repetitions may support various techniques for uplink coverage enhancement and diversity gains.

Abstract: A method of resolving an uplink collision and pre-empting portions of an uplink channel is provided. A UE receives an uplink cancellation indication from a base station. The UE identifies that a UCI transmission on a PUCCH transmission overlaps with a second uplink transmission. The UE determines whether to apply the ULCI to the PUCCH transmission and the second uplink transmission before or after applying a multiplexing rule to resolve the collision. The UE transmits an uplink communication to the base station based on the ULCI and the multiplexing rule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some techniques and apparatuses described herein provide resolution of ambiguity with regard to determination of an open loop power control value (e.g., a P0 value) for a user equipment that is configured with at least two downlink control information formats, of which one is configured with a sounding reference signal resource indicator (SRI) field and another is not configured with an SRI field. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support resolution of uplink (UL) transmission overlap of communication types having different priorities. In some implementations, a method of wireless communication includes determining, at a user equipment (UE), that a first scheduled UL transmission corresponding to a first communication type having a first priority overlaps with a second scheduled UL transmission corresponding to a second communication type having a second priority. The first priority is higher than the second priority. The method also includes multiplexing at least a portion of the first scheduled UL transmission with at least a portion of the second scheduled UL transmission to generate a third UL transmission. The method further includes transmitting, from the UE to a base station, the third UL transmission. Other aspects and features are also claimed and described.

Abstract: A method of wireless communication includes selecting, by a user equipment (UE), a first codepoint from a codebook based on control information to be transmitted to a base station. The codebook is associated with non-coherent transmissions from the UE to the base station. The method further includes generating, based on the first codepoint and a scrambling sequence that is associated with the UE, a second codepoint representing the control information. The method further includes transmitting the second codepoint by the UE to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive switching information to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP, the first SL-BWP and the second SL-BWP being configured for sidelink communications. The UE may transmit or receive data associated with a sidelink communication based at least in part on the switching information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive multiple requests for sidelink channel state information (CSI) and each request for sidelink CSI may trigger a different sidelink CSI report from the UE. The UE may assign a number of CSI processing units (CPUs) to each triggered sidelink CSI report and may select one or more of the triggered sidelink CSI reports for generation in accordance with a CPU capability of the UE and according to a priority associated with each of the requests. For example, the UE may select the one or more CSI reports in an order according to the priority and such that a summation of the CPUs assigned to each of the selected CSI reports avoids exceeding the CPU capability of the UE. The UE may generate and transmit the selected CSI reports.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support managing compression and compression indications of a low-priority (LP) uplink control information (UCI) message that is multiplexed with a high-priority (HP) UCI message in a wireless communication system. In particular, a user equipment (UE) determines a compression indication for the LP UCI message, encodes the compression indication jointly with the HP UCI payload, and separately encodes the LP UCI payload. The encoded LP UCI payload is multiplexed with the jointly-encoded compression indication and HP UCI payload in an uplink transmission to a base station. The compression indication includes information related to whether and how the LP UCI has been compressed. The base station decodes the compression indication and then decodes the LP UCI message based on the compression indication.

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.
