Abstract: A method of wireless communication by a sidelink user equipment (UE) includes selecting a sidelink wakeup signal (WUS) resource from a dedicated sidelink WUS resource pool. The sidelink WUS resource pool differs from a sidelink data transmission resource pool. The method also includes transmitting, to a receiver, a WUS on the selected sidelink WUS resource.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a configuration of a set of cells configured for layer 1 (L1) or layer 2 (L2) inter-cell mobility. The UE further transmits a special cell (SpCell) update message in response to an SpCell change condition on the first SpCell in the set of cells for the L1 or L2 inter-cell mobility. The SpCell change condition may include a beam failure on the first SpCell. The method improves the quality of service, beam reliability, and resource utilization of wireless communication, and reduces latency and power consumption of wireless communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first apparatus may receive a synchronization signal from an external device. The first apparatus may communicate in a wireless network using a licensed access protocol that is based at least in part on time division multiplexing (TDM) that uses a time boundary associated with the synchronization signal, the communicating being based at least in part on a frequency band that is allocated to a licensed access mode and an unlicensed access mode. A second apparatus may communicate in a wireless network using a synchronized unlicensed access protocol that is based at least in part on a synchronization signal time boundary associated with the synchronization signal, the communicating being based at least in part on the frequency band that is allocated to a licensed access mode and an unlicensed access mode. Numerous other aspects are described.

Abstract: A method for wireless communication by a user equipment (UE) includes receiving an indication of a mobility configured cell set having a number of cells. The method also includes receiving signaling to release a selected cell from the mobility configured cell set. The method further includes releasing the selected cell from the mobility configured cell set in response to receiving the signaling. In some aspects, releasing the selected cell comprises removing the selected cell from a carrier aggregation configuration. In other aspects, releasing the selected cell comprises removing a mobility configuration for the selected cell.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: Aspects presented herein may improve the latency and efficiency of L1/L2 inter-cell mobility. In one aspect, a UE receives a configuration for a set of cells associated with a mobility of the UE, where the set of cells includes an SpCell and an SCell, where the set of cells includes a first subset of activated cells and a second subset of deactivated cells, and where at least one first cell of the set of cells is a reference cell and one or more second cells of the set of cells are associated with the reference cell. The UE receives an indication of an updated configuration for the set of cells based on a movement of the UE, where the indication of the updated configuration is received from the network entity, where the updated configuration includes at least one new cell in the set of cells.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive configuration information, the configuration information indicating that a Layer 1 / Layer 2 (L1/L2) control signal is to be used to indicate when the network node is to: switch from additional transmission reception point (TRP) functionality to primary TRP functionality for a primary serving cell, or switch from a secondary serving cell to the primary serving cell and activate the primary TRP functionality. The network node may receive the L1/L2 control signal. The network node may activate, based at least in part on the L1/L2 control signal, the primary TRP functionality. Numerous other aspects are described.

Abstract: Aspects of the disclosure provide techniques for enabling cell synchronization and timing adjustment management in layer 1 and layer 2 (L1-L2) centric mobility applications. A user equipment (UE) communicates with a network entity using one or more cells of a plurality of cells that are configured for mobility operations using layer 1 and layer 2 (L1-L2) centric signaling. The plurality of cells are grouped into one or more timing adjustment groups (TAGs). The UE updates timing advance of the plurality of cells per group according to the one or more TAGs.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.
