Abstract: Systems and methods for sidelink transmission. In some embodiments, a method includes: determining, by a User Equipment (UE), a measure of channel congestion, the measure of channel congestion being a channel busy ratio or a channel occupancy ratio; determining, by the UE, a determined contention window size, based on the measure of channel congestion; and waiting, during a first interval of time, without making a sidelink transmission, wherein a length of the first interval of time is based on the determined contention window size.

Abstract: Disclosed is a method of a gNB, including encoding a low power wake up signal (LP-WUS) payload using a line coding scheme, mapping a line coding output of the line coding scheme to baseband symbols using a keying modulation, mapping symbols of the keying modulation to baseband LP-WUS blocks, and transmitting the baseband LP-WUS blocks to at least one UE

Abstract: A system and a method are disclosed for providing enhancements to Semi-Persistent Scheduling (SPS) to match traffic, while also providing power savings, resource utilization and HARQ enhancements related to traffic and SPS configurations. A SPS configuration may include one or more occasions in a Physical Downlink Shared Channel (PDSCH) of a wireless network for traffic for a wireless device. In response to the SPS configuration, the wireless device receives the traffic in the scheduled occasions. The SPS configuration may include one or more occasions in at least one time slot in a SPS period. At least one occasion may align with a target periodicity of the traffic. The SPS configuration may include different configuration states, and a Downlink Control Information (DCI) message may be used to indicate to a wireless device which SPS configuration state to use to receive the traffic.

Abstract: A method of performing a timing advance adjustment between a user equipment (UE) and a non-terrestrial network (NTN) includes receiving and decoding a medium access control (MAC) control element (CE) including closed loop information; receiving and decoding system information including open loop information; determining a timing advance value based on either the closed loop information or the open loop information; and controlling timing of an uplink transmission signal, transmitted from the UE, based on the timing advance value.

Abstract: A system and method for managing downlink data transmissions with HARQ feedback disabled. In some embodiments, the method includes: receiving, by a User Equipment (UE), a downlink data transmission with Hybrid Automatic Repeat reQuest (HARQ) feedback disabled; and multiplexing, by the UE, a plurality of HARQ-acknowledgment (HARQ-ACK) information bits to form a HARQ-ACK codebook, wherein the multiplexing of the HARQ-ACK information bits does not include multiplexing a HARQ-ACK information bit for the downlink data transmission in the HARQ-ACK codebook.
