摘要： Certain aspects of the present disclosure provide a method for wireless communications by a transmitter user equipment (UE). The method may include transmitting, to a receiver UE, sidelink control information (SCI) to reserve a future sidelink resource for a sidelink transmission to the receiver UE, wherein the SCI indicates transmission of the sidelink transmission will begin with a cyclic prefix (CP) extension (CPE). The method may further include transmitting, to the receiver UE, the sidelink transmission with the CPE on the future sidelink resource in accordance with the SCI.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information indicating precoding information associated with a multi-panel uplink transmission, the precoding information including at least one of a demodulation reference signal port configuration associated with the multi-panel uplink transmission, a multiple-input multiple-output precoding configuration associated with the multi-panel uplink transmission, or a quantity of layers associated with the multi-panel uplink transmission. The UE may precode the multi-panel uplink transmission for transmission via a first antenna panel of the UE and a second antenna panel of the UE based at least in part on the precoding information. The UE may transmit, using the first antenna panel and the second antenna panel, the precoded multi-panel uplink transmission. Numerous other aspects are provided.

摘要： The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, SPS via RRC signaling. The apparatus may also determine a UE Rx-Tx time difference, the UE Rx-Tx time difference being equal to a difference between a downlink subframe reception time and an uplink subframe transmission time. The apparatus may also transmit, to the base station, the UE Rx-Tx time difference or receive, from the base station, a base station Rx-Tx time difference, the base station Rx-Tx time difference being equal to a difference between an uplink subframe reception time and a downlink subframe transmission time.

摘要： Wireless communication systems and methods related to channel occupancy time (COT) sharing when operating in a frame-based-equipment (FBE) mode over a shared frequency band are provided. In one aspect, a user equipment (UE) contends for a channel occupancy time (COT) in a first frame-based equipment (FBE) frame. The UE transmits, to a base station (B S), an uplink communication signal during a first portion of the COT. The UE receives, from the BS based on COT sharing information, a downlink communication signal during a second portion of the COT, wherein the second portion is non-overlapping with the first portion

摘要： Aspects relate to an uplink channel resource indication for dynamic time division duplex systems where a number of various slot formats may be utilized. A slot format indicator (ID) for a physical uplink control channel (PUCCH) may be mapped to a respective uplink channel resource identifier (ID). The mapping correlates the slot format ID with the uplink channel resource ID to thereby identify at least one particular sub-slot or symbol in a slot usable for uplink (UL) transmissions on the uplink channel.

摘要： Aspects of the present disclosure provide techniques for handling scenarios where a physical uplink shared channel (PUSCH) repetition is scheduled as a single symbol. According to certain aspects, a user equipment (UE) is configured to detect that a nominal physical uplink shared channel (PUSCH) repetition is to be segmented into one or more actual PUSCH repetitions that include a single symbol actual PUSCH repetition and take one or more actions to handle a symbol length gap in transmission due to the single symbol actual PUSCH repetition.

摘要： Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently identifying resources for transmitting one or more sidelink synchronization signal blocks (S-SSBs) in the shared spectrum or efficiently beam sweeping multiple S-SSBs in the shared spectrum. In one aspect, a user equipment (UE) may transmit an S-SSB in a sidelink bandwidth part (BWP) in the shared spectrum such that a lower edge of the S-SSB is aligned with or offset from a lower edge of the sidelink BWP. In another aspect, a UE may beam sweep S-SSBs in one or more S-SSB bursts in a S-SSB period to improve the chances that another UE may receive the S-SSBs. In yet another aspect, resources allocated for S-SSB transmissions may facilitate flexible S-SSB transmissions while minimizing gaps to prevent other UEs from incorrectly determining that a sidelink BWP in a shared spectrum is clear for transmission.

摘要： Certain aspects of the present disclosure provide techniques for multiplexing aperiodic channel state information (AP-CSI or A-CSI) or semi-periodic CSI (SP-CSI) on multiple physical uplink share channel (PUSCH) repetitions. For example, according to certain aspects, a method for wireless communications at a user equipment (UE) includes obtaining signaling indicating that the UE is to multiplex aperiodic channel state information (A-CSI) with the at least two PUSCH repetitions when one or more conditions are met, obtaining signaling scheduling the UE to transmit the at least two PUSCH repetitions, wherein the at least two PUSCH repetitions are associated with a first sounding reference signal (SRS) resource set, and outputting the at least two PUSCH repetitions for multiplexing with the A-CSI based on the signaling indication and the one or more conditions.

摘要： Methods, systems, and devices for wireless communications are described. A UE may identify a configuration of sidelink synchronization signal block instances including a first quantity of sidelink synchronization signal block instances for each of a plurality of sidelink synchronization signal block periods. The UE may transmit a second quantity of sidelink synchronization signal block instances over a first sidelink synchronization signal block period. In some aspects, the UE may transmit a sidelink synchronization signal block burst using beams in a sidelink synchronization signal block period. The UE may identify a configuration for a set of resources of a sidelink beam selection resource pool based on transmitting the sidelink synchronization signal block burst. The UE may receive, from another UE over the set of resources, a control message including an indication of preferred beams. The UE may transmit the sidelink data to the other UE using the preferred beams.
