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: Some aspects described herein relate transmitting, to a receiving UE, a sidelink control information (SCI) that schedules multiple transport blocks (TBs) of shared channel communications in multiple time divisions, and transmitting, to the receiving UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Other aspects relate to receiving, from a transmitting UE, a SCI that schedules multiple TBs of shared channel communications in multiple time divisions, and receiving, from the transmitting UE and based on the SCI, the multiple TBs of shared channel communications in the multiple time divisions. Additional aspects relate to configuring the UEs in this regard.

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.

Abstract: 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.

Abstract: 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.

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 via a sidelink sub-channel of a licensed carrier, an indication of multiple data channels of an unlicensed carrier to be used to attempt one or more sidelink communications between the first UE and the second UE. The UE may attempt the one or more sidelink communications between the first UE and the second UE using the multiple data channels. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.
