Abstract: Certain aspects of the present disclosure provide techniques for the coexistence of wireless telecommunication devices (e.g., 4G, 5G, and/or 6G devices) and UWB devices operating in a same frequency band. A method generally includes receiving, from a first user equipment (UE), first signaling indicating an initiation of a first ultra-wideband ranging session between the first UE and an ultra-wideband device; determining a location of the first UE after receiving the first signaling; and performing one or more first interference mitigation processes configured to reduce channel interference in a first ultra-wideband channel used for the first ultra-wideband ranging session based on, at least, the location of the first UE.

Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in discovering and cooperating with other UEs. A BS may collect information from candidate cooperative UEs such as UE capability and availability. This information may be broadcast to other UEs or may be transmitted to a UE at the UE's request. The UE may, upon receipt of this information, use it to aid in discovering the candidate cooperative UEs and/or establishing a connection.

Abstract: A method of wireless communication by an initiating device, includes acquiring a channel occupancy time (COT) including multiple subsets of COT sharing resources. Each of the subsets includes fewer resources than the entire COT. The method also includes configuring a first responding device with a first of the subsets of COT sharing resources. The method further includes configuring a second responding device with a second of the subsets of COT sharing resources. A method of wireless communication by a responding device receives, from an initiating device, a first subset of multiple subsets of channel occupancy time (COT) sharing resources. The first subset differs from a second subset of COT sharing resources configured for another device. The method also includes selecting transmission resources from the first subset of COT sharing resources in response to detecting the initiating device acquired the COT, and then transmitting data on the selected transmission resources.

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.
