摘要： 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.

摘要： 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.

摘要： Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions across multiple transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the TTIs being indicated as passing the LBT channel access procedure based on the performance.

摘要： Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

摘要： 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.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration of a resource pool for configured grant uplink communications, wherein the resource pool is associated with an admission probability parameter that controls an admission probability for access to the resource pool; receive an indication that modifies the admission probability; and perform an admission control procedure to attempt access to the resource pool for transmission of a configured grant uplink communication based at least in part on the indication, wherein the admission control procedure is associated with the modified admission probability. Numerous other aspects are provided.
