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, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Methods, systems, and devices for wireless communications are described to support determination of an uplink beam for uplink transmissions. A base station may configure a user equipment (UE) with multiple sets of sounding reference signal (SRS) resources that may be used for uplink transmissions from the UE. In some cases, each set of SRS resources may be configured with one associated channel state information reference signal (CSI-RS) resource, and each CSI-RS resource may correspond to an uplink beam. The base station may transmit a downlink control message to the UE, indicating one or more selected SRS resource sets and one or more selected SRS resources within each of the one or more selected SRS resource sets. The UE may transmit an uplink transmission with a beam associated with the indicated SRS resource set.

Abstract: Methods, systems, and devices for multi-channel wireless communications using shared radio frequency spectrum are provided. Prior to multi-channel transmissions, a user equipment (UE) may perform a separate listen before talk (LBT) procedure for each channel. Prior to performing the LBT procedures, the UE may identify a set of channels that are to be used for the multi-channel transmission, where the set of channels may include less channels than are allocated or configured to the UE for a slot. The UE identify the set of channels based on one or more multiplexing and prioritization procedures for uplink communications that are allocated or configured for a slot, and determine the set of uplink channels after performing the multiplexing and prioritization procedures. In some cases, the multiplexing and prioritization procedures may include intra-UE multiplexing and prioritization procedures, inter-UE multiplexing and prioritization procedures, or combinations thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) or a base station may generate a discrete Fourier transform (DFT) waveform from separate DFT inputs of data content, a guard interval (GI) sequence, and tail suppression samples. The UE or the base station may generate a first communication with the DFT waveform using an inverse fast Fourier transform (IFFT) operation. The first communication may include, in a time domain, a data signal corresponding to the data content and a GI-based tail signal that corresponds to the GI sequence and that is suppressed with a tail suppression signal based at least in part on the tail suppression samples. The UE or the base station may transmit the first communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first set of resources associated with a semi-persistent scheduling (SPS) acknowledgement/negative acknowledgement (A/N) feedback message, wherein the SPS A/N feedback message is deferred to a second set of resources by the UE. The UE may receive an indication of a third set of resources associated with a dynamic A/N feedback message, wherein the second set of resources and the third set of resources are associated with a collision. The UE may perform an action based on the second set of resources and the third set of resources being associated with the collision. The UE may transmit at least one of the SPS A/N feedback message or the dynamic A/N feedback message based on performing the action. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink user equipment (UE) may transmit, to a second sidelink UE via sidelink control information (SCI), a receiving (Rx) beam schedule indicating Rx beams associated with the first sidelink UE in a set of slots, wherein the Rx beam schedule indicates that the first sidelink UE is configured to tune to the Rx beams in the set of slots for possible sidelink receptions. The first sidelink UE may receive, from the second sidelink UE, a sidelink transmission using an Rx beam indicated in the Rx beam schedule. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a helper user equipment (UE) may receive, from a base station, a signaling message requesting the helper UE to monitor for and transmit a sidelink communication in a manner that uses a single-frequency network, wherein the sidelink communication is to be transmitted by a source UE to a destination UE that is different from the helper UE. The helper UE may receive the sidelink communication, transmitted by the source UE to the destination UE, in a first time-frequency resource of the single-frequency network. The helper UE may transmit the sidelink communication in a second time-frequency resource of the single-frequency network, wherein the second time-frequency resource is indicated to the helper UE by the base station. Numerous other aspects are described.

Abstract: Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.
