Abstract: In the context of a slot of a sidelink (SL) communication frame of a user equipment (UE), the slot is configured with a resource element allocation comprising an SL synchronization signal block (S-SSB) occupying a plurality of less than all symbols of the slot, and a plurality of less than all subcarriers of a channel of the slot. The UE determines that an occupied channel bandwidth (OCB) constraint for the slot across the channel will not be met with the resource element allocation. The UE then multiplexes, in response to the determining, a reference signal (RS) across the symbols occupied by the S-SSB in a plurality of resource blocks of the channel not occupied by the S-SSB to meet the OCB constraint. The UE then transmits the slot with the S-SSB and the multiplexed RS.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive control signaling indicating a configuration for performing a sidelink discontinuous reception procedure, where the configuration indicates a duration of a timer associated with an active duration for the first UE to receive sidelink retransmissions during the sidelink discontinuous reception procedure. The UE may then receive a first sidelink communication including data and may, in some cases, transmit feedback requesting a retransmission of the data. The UE may then receive second sidelink communication including the retransmitted data. Prior to receiving the second sidelink communication including the retransmitted data, the UE may initiate the timer according to the configuration. Thus, the UE may be in an active mode to receive the second sidelink communication.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter user equipment (UE). The method may include receiving (e.g., from a network entity) a configuration of a first resource pool associated with a second resource pool. The first resource pool includes physical sidelink feedback channel (PSFCH) resources for hybrid automatic repeat request (HARQ) responses for physical sidelink shared channel (PSSCH) transmissions in the second resource pool. The method further includes transmitting (e.g., to a receiver UE) a PSSCH on a resource in the second resource pool and a request for a HARQ response for the PSSCH from a PSFCH resource in the first resource pool. The method further includes receiving (e.g., from the receiver UE) the HARQ response over the PSFCH resource (e.g., in response to the PSSCH).

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide for a user equipment (UE) performing contention-based access to utilize historical pathloss measurements to identify available resources for beamformed sidelink communications. The historical pathloss measurements may be obtained by the UE, by one or more other UEs, or both, where the UE may combine its own historical pathloss measurements with historical pathloss measurements obtained at the one or more other UEs. Such historical pathloss measurements may allow the UE to determine if one or more beam combinations associated with the resources may cause unacceptable interference (e.g., interference satisfying a threshold) while reducing signaling overhead associated with exchanges of inter-UE coordination messages. Accordingly, the UE may determine to yield transmissions over one or more resources or to yield reception to allow other UEs to utilize the one or more resources.

Abstract: Techniques for dynamic time duplex division (TDD) with reservation signal and contention may include a first network node configured to select a first resource to reserve for use of a downlink (DL) transmission or an uplink (UL) transmission. The first network node may also be configured to transmit, to a second network node, a reservation signal on a reservation signal resource to announce that the first resource is reserved for use of the DL transmission or the UL transmission by the first network node. The reservation signal resource may be associated with the first resource.

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: Disclosed are techniques for wireless communication. In an aspect, a UE determines a sidelink resource configuration for a slot, wherein the sidelink resource configuration includes a first set of resources carrying a first PSSCH in a first mini-slot of the slot, a second set of resources carrying a second PSSCH in a second mini-slot of the slot, and a third set of resources carrying a PSFCH associated with one or more PSSCHs of one or more preceding slots. The UE may communicate data over at least a portion of the slot in accordance with the sidelink resource configuration. In some designs, a sidelink management device (e.g., the UE, another UE, or a network component) may transmit the sidelink resource configuration.

Abstract: Wireless communications systems and methods related to channel occupancy time-sharing information (COT-SI) reservation of a COT for sidelink communications in an unlicensed band are provided. In some aspects, a user equipment (UE) performs a channel access procedure to acquire one or more COTs in a sidelink channel over an unlicensed new radio (NR) band. Further, the UE transmits a COT sharing information (COT-SI) configured to reserve the one or more COTs for a future transmission via the sidelink channel.
