A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Disclosed are methods and apparatus to process delay for PDCCH repetition. A transmission of a physical downlink control channel (PDCCH) repetition may be monitored. A multiplexing pattern of the PDCCH repetition and a physical downlink shared channel (PDSCH) within an overlapping symbol may be determined. A processing delay for a decoding of the PDCCH repetition, a decoding of the scheduled PDSCH, and an acknowledgement (ACK) preparation based on the multiplexing pattern of the PDCCH repetition and the PDSCH within the overlapping symbol may be determined. The PDSCH may be monitored after receiving the PDCCH repetition.

A UE may transmit a message comprising information regarding one or more physical random access channel (PRACH) capabilities of the UE to a base station (BS). The UE may then receive, from the BS, signaling comprising an indication of one or more configured PRACH formats supporting the one or more PRACH capabilities. Next, the UE may transmit, using the one or more configured PRACH formats, one or more preambles to the BS in a random access (RACH) procedure. Accordingly, the UE may receive a random access response (RAR) from the base station and further, in response to receiving the RAR, establish a connection with the BS.

Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Power saving sensing for reduced sensing UES using resource re-evaluation and resource pre-emption

Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values P(and optionally period definition data K). Restrictions on the use of random resource selection by the UE are also described.
