Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sidelink synchronization signal block (S-SSB) with a high priority listen-before-talk (LBT) parameter. The UE may communicate with an other UE based at least in part on the S-SSB with the high priority LBT parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a secondary user equipment (UE), a first grant to conditionally transmit one or more data messages over a first set of resources upon completion of a detection procedure. The detection procedure may include monitoring a second set of resources for over-the-air (OTA) signals transmitted by a primary UE pursuant to a second grant, where the first set of resources at least partially overlaps the second set of resources. The UE may monitor for the OTA signals from the primary UE, determine that one or more conditions for transmission of the one or more data messages have been satisfied, and transmit the one or more data messages over the first set of resources.

Abstract: Aspects for reducing interference for transmissions in unlicensed frequency bands are disclosed. An apparatus, e.g., a user equipment (UE) with information to transmit, identifies before transmitting the information in an unlicensed frequency spectrum, a specified duration of a listen-before-talk (LBT) operation in that spectrum. Based on the specified duration, the UE reduces a transmission time duration of a slot of the UE to increase a time duration of a remainder of the slot sufficient to prevent, or decrease the likelihood of, a transmission by the UE in the slot from interfering with an LBT operation by another UE.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink beamforming alignment over a set of resources based on a deterministic sequence in a wireless communication system. In aspects, an sidelink initiator user equipment (UE) may initiate a beamforming alignment procedure with a responder UE over a the sidelink. The initiator UE may define a set of subchannels specified by a deterministic sequence. The set of subchannels may be subchannels over which the initiator UE may perform reception beam sweeping. The deterministic sequence may be anchored to a direct frame number (DFN) of the sidelink frame without initial sensing, and may be determined via a sequence index, as a function of sidelink UE identification ID(s), or a combination thereof. In this manner, the number of bits for indicating the deterministic sequence to the responder UE may be reasonable, manageable, and/or moderate.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sidelink synchronization signal block (S-SSB) in a slot. The UE may transmit remaining minimum system information (RMSI) associated with the S-SSB, wherein the RMSI is transmitted in a physical sidelink shared channel (PSSCH) that is multiplexed with the S-SSB in the slot. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A source user equipment (UE) may transmit, to a relay UE, information identifying that the relay UE is one of a plurality of relay UEs selected for cooperative relaying of a communication from the source UE to a destination UE. A channel between the source UE and the relay UE may be one of a plurality of channels comprising a channel between the source UE and each relay UE of the plurality of relay UEs. The plurality of relay UEs may be selected based at least in part on a degree of correlation of the channel between the source UE and the relay UE with at least one other channel of the plurality of channels. The UE may transmit the communication to the plurality of relay UEs for cooperative relaying to the destination UE. Numerous other aspects are described.

Abstract: 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.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), an indicator associated with occupancy of a channel-access gap symbol and transmitting, to a second sidelink UE, a first physical sidelink shared channel (PSSCH) communication via the channel-access gap symbol based on the indicator associated with the occupancy of the channel-access gap symbol.

Abstract: 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.
