Abstract: Certain aspects of the present disclosure provide techniques for signaling a user equipment (UE) to put a sidelink (SL) component carrier (CC) into dormancy or take the SL CC out of dormancy, such as mode 1 or mode 2 sidelink communications. In one example, a method performed by a UE includes receiving an indication to put a first CC into dormancy; and putting an SL CC into a dormant state in response to the indication. In another example, a method includes transmitting an indication that the first UE will put an SL CC into a dormant state; and receiving an acknowledgment (ACK) of the indication.

Abstract: Certain aspects of the present disclosure provide techniques for channel reservation for sidelink. In some embodiments, the disclosure describes determining a resource allocation for communicating over a plurality of subchannels within a slot, wherein the resource allocation provides: (i) a first set of subchannels of the plurality of subchannels allocated for communicating data to multiple UEs, and (ii) a first subchannel of the plurality of subchannels allocated for communicating a group reservation signal comprising communication parameters indicative of at least the resource allocation for the first set of subchannels.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine candidate resources on one or more physical sidelink shared channels (PSSCHs) that are clear for transmitting at least two transport blocks, based at least in part on sensing a plurality of subchannels on the one or more PSSCHs with respect to listen-before-talk completion instants for the at least two transport blocks. The UE may select, from among the candidate resources, transmit resources on the one or more PSSCHs for transmitting the at least two transport blocks such that the at least two transport blocks are transmitted in one of: different subchannels of a same slot, or contiguous slots of a same subchannel. The UE may transmit the at least two transport blocks in the transmit resources. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, for a sidelink transmission over an unlicensed band and associated with a medium access control (MAC) protocol data unit (PDU), one or more candidate resources of a set of candidate resources that are within an adaptive effective contention window (ECW). The UE may adjust at least one parameter of the adaptive ECW to determine an adjusted at least one parameter based at least in part on a channel access output associated with the one or more candidate resources. The UE may transmit the MAC PDU using the one or more candidate resources or an additional one or more candidate resources, wherein the additional one or more candidate resources are selected based at least in part on the adjusted at least one parameter. Numerous other aspects are provided.

Abstract: A UE receives an SSB having an SSB index and transmits a random access message using a PRACH resource based on a mapping to a number (X) of preamble sequences that are allocated for SSBs first in a sequence domain within a RO, second in a frequency domain RO within the single RB set, third in a time domain RO within a PRACH slot, and fourth within a PRACH slot domain within a time period. of preamble sequences that are allocated for SSBs first in an order first based on a sequence domain within a RO, second in a frequency domain of the RO within a single RB set, third in a time domain of one or more ROs within a PRACH slot, and fourth within a PRACH slot domain that is within a time period.

Abstract: A method of wireless communication performed by a first user equipment (UE) includes receiving second data from a remote UE and receiving an uplink transmission grant from a base station. The method also includes generating a payload comprising the second data from the second UE or first data from the first UE. The method additionally transmits the payload to the base station via an uplink resource identified in the uplink transmission grant.

Abstract: A configuration to allow for the transmission of system information on different beams, where different transmission parameters may be utilized for different beams. The apparatus transmits system information on a first beam. The apparatus transmits the system information on a second beam. The system information is transmitted using different parameters for the first beam and the second beam or comprises different system information content for the first beam and the second beam.

Abstract: Aspects of the present disclosure provide techniques that help reducing transmission overhead related to sidelink control information (SCI). For example, when a transmitter UE has established a sidelink communication with a receiver UE, the transmitter UE may schedule with at least one semi-persistent scheduling (SPS) process at a first time interval. The transmitter UE may sense whether a resource is available for transmissions to the receiver UE based on decoding an SCI, such as an SCI 0-1 message. The SCI is transmitted at a second time interval that is greater than the first time interval. For example, the second time interval may be a multiple of the first time interval of the at least one SPS process. The second time interval may be flexible and may be increased to reduce the number of SCI messages transmitted in certain time periods in order to reduce communication overhead.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.
