Abstract: Techniques for a wireless device to share a Channel Occupancy Time (COT) in a sidelink (SL) channel are disclosed. The techniques include a method for sharing a Channel Occupancy Time (COT) in a sidelink (SL) channel that includes performing a Clear Channel Assessment (CCA) by a first wireless device to initialize the COT. The first wireless device determines that a portion of the COT may be shared, and transmits to one or more qualifying wireless devices, first Sidelink Control Information (SCI). The first SCI may include a destination identification (ID), an offset, and a SL duration. The destination ID indicates one or more qualifying wireless devices that may share the COT, and the SL duration defines a duration of time available for the one or more qualifying wireless devices to share the COT. The first wireless device may resume transmission in the COT.

Abstract: In accordance with aspects of the present disclosure, a user equipment (UE) may receive a physical sidelink shared channel (PSSCH) transmission via a slot i and a sub-channel j. The UE may determine, within a resource block (RB) set k and a physical sidelink feedback channel (PSFCH) transmission occasion n, at least one interlace to use for a PSFCH transmission based at least in part on an index of the slot i, an index of the sub-channel j, a PSFCH periodicity, and a quantity of sub-channels in the RB set k. The UE may transmit the PSFCH transmission via the at least one interlace in the RB set k during the PSFCH transmission occasion n. The PSFCH transmission may include feedback for the PSSCH transmission.

Abstract: A user equipment (UE) may include a main radio (MR) and a Low Power Wake-Up Radio (LR). The UE may coordinate periods where the MR and LR are on and off. For example, the UE may enter a deep sleep state by turning off a main radio (MR) of the UE, and turning on a Low Power Wake-Up Radio (LR) of the UE. The MR may receive an event indication from the LR to turn on the MR. The MR may turn on and perform a procedure according to an event corresponding to the event indication.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: obtaining a first configured grant (CG) configuration for an uplink (UL) carrier and a second CG configuration for a supplementary uplink (SUL) carrier, each of the first and second CG configurations comprising multiple transmission occasions, generating at least one unused transmission occasion uplink control information (UTO-UCI), the at least one UTO-UCI indicating which of the multiple transmission occasions are unused by a user equipment (UE) for each of the first CG configuration and the second CG configuration, and instructing radio frequency (RF) circuitry to transmit the at least one UTO-UCI to an access node.

Abstract: A method for performing a contention-free random access (CFRA) in a lower-layer triggered mobility (LTM) procedure from a serving cell to a target candidate cell is provided. The method includes determining, by a user equipment (UE), that random access response (RAR) reception is not configured for the UE. The method includes receiving, by the UE, a physical downlink control channel (PDCCH) order for transmitting a physical random access channel (PRACH) signal to the target candidate cell. The method includes determining, by the UE and based on the PDCCH order, a transmission power for transmitting the PRACH signal.
