Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

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: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

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: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.

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.

Abstract: Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.

Abstract: This disclosure relates to techniques for aligning wireless device and cellular network expectations and behavior in conjunction with neighbor cell measurements in a wireless communication system. A wireless device may determine that a reference signal is configured for a neighbor cell measurement when communication with the serving cell is also configured. The wireless device may determine whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell. The wireless device may select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell.
