Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

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).
