Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide DRX groups for licensed and unlicensed bands. For example, a first DRX group can be used in association with an NR licensed band of FR1, a second DRX group can be used in association with NR-U of FR1, and a third DRX group can be used in association with FR2. In this way, power savings of DRX groups can be granular to the level of licensed and unlicensed bands.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for triggering earlier Channel State Information (CSI) feedback, comprising: transmitting, by a wireless device to a wireless station, an indication to provide earlier CSI feedback (e.g., wherein the indication comprises an indication that the wireless device has a reduced capability to receive messages); receiving from the wireless station, in response to the indication, a modified message (e.g., a Downlink Control Information or modified Medium Access Control Random Access Response), wherein the modified message triggers an earlier CSI feedback from the wireless device; transmitting to the wireless station, in response to receiving the modified message, the earlier CSI feedback using a message related to a RACH procedure (e.g., a Msg3); and completing a connection to the wireless station, e.g., in response to a repeated number of initial access messages broadcast from the wireless station and based on the transmitted CSI feedback.

Abstract: A user equipment (UE), including a vehicle to everything (V2X) device, a baseband processor or other network device can operate in an unlicensed network to acquire a channel occupancy time (COT) for sidelink (SL) transmission and provide sidelink control information (SCI) with a first stage SCI in a physical sidelink control channel (PSCCH) and a second stage SCI in a physical sidelink shared channel (PSSCH). The first stage SCI or the second stage SCI can provide COT indications to a receiving UE device that enable COT sharing in a sidelink unlicensed COT (SL-U COT) for SL communication.

Abstract: Disclosed are methods and apparatus to enhance RACH transmission for beyond 52.6 GHz communications. A Physical Random Access Channel (PRACH) configuration information including an indication of a PRACH preamble format for a predefined subcarrier spacing (SCS) to enhance cell coverage may be received. The PRACH configuration information may include a new PRACH preamble format in a time-domain based on a short sequence PRACH preamble format. Additionally, the PRACH preamble may be transmitted using the PRACH preamble format over a PRACH to a base station (BS). The short sequence PRACH preamble format may be repeated over two consecutive time-domain RACH occasions (ROs).

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a vehicle-to-everything (V2X) capable wireless device configured to perform sidelink cellular communications. The wireless device performs sidelink communications using a two-stage sidelink control information (SCI) protocol including Stage 1 SCI messaging carried on a physical sidelink control channel (PSCCH), and Stage 2 SCI messaging carried on a physical sidelink shared channel (PSSCH). The SCI messaging may be encoded using polar codes. Channel interleaving is utilized on the SCI to interleave the SCI between two or more layers of a MIMO transmission system. Scrambling for Stage 2 SCI messaging is performed based on the result of a cyclic redundancy check (CRC) performed on Stage 1 SCI messaging. Collisions between sidelink HARQ feedback to be transmitted to a base station and other transmissions are avoided based on a priority analysis of the sidelink HARQ feedback.
