Abstract: Enhancement for bandwidth part (BWP) is disclosed. A base station configures a plurality of BWPs, and activate multiple BWPs for downlink and multiple BWPs for uplink from the plurality of the configured BWPs at a given time. Downlink control information (DCI) that includes BWP activation information can be transmitted on a physical downlink control channel (PDCCH) to a user equipment (UE). The BWP activation information includes a link direction, a schedule of the one or more multiple BWPs for downlink and multiple BWPs for uplink, numerologies, reserved sub-band information, tracking reference signal configuration, or any combination thereof. Correspondingly, a UE receives DCI on a PDCCH that includes BWP activation information, and determines activation of multiple BWPs for downlink and multiple BWPs for uplink at a given time based on the received DCI and its capabilities. Associated enhancement for PDCCH and PDSCH scheduling and LBT procedures are also disclosed.

Abstract: Aspects of the disclosure relate to wireless communication over a shared spectrum carrier utilizing a broadcast, common control channel. The broadcast control channel may be multiplexed with a unicast control channel. Further, a scheduling entity may allocate a semi-static set of resources for the broadcast control channel, providing a shared search space on the shared spectrum carrier. The resource allocation for the shared search space may be based on one or more parameters, which may be cell-specific parameters. This shared search space may include resources distributed across the shared spectrum carrier, or a contiguous set of resources that spans only a portion of the carrier. The broadcast control channel may be configured for high reliability, and may carry time-critical control information relating to access control for the shared spectrum carrier. Other aspects, embodiments, and features are also claimed and described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a user equipment (UE), which may include a reduced capability (RedCap) UE, and a supporting cell. The UE may receive a synchronization signal block (SSB). The UE may receive a configuration of an active downlink bandwidth part (BWP) that is not configured with a SSB. The UE may tune, from the active downlink BWP to a different frequency for a layer 1 (El) measurement gap defined by a El measurement gap configuration. The UE may perform a El measurement of the SSB on the different frequency during the El measurement gap. The UE may be a RedCap UE, the active BWP may be for RedCap UEs, and the SSB may define an initial BWP for the RedCap UEs and non-RedCap UEs, and the different frequency may be the initial BWP.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a reduced capability (RedCap) user equipment (UE) and supporting cell. The RedCap UE is configured with multiple bandwidth parts (BWPs). A maximum bandwidth of the RedCap UE is lower than a maximum bandwidth of a non-RedCap UEs. The UE receives a cell-defining synchronization signal block (CD-SSB) that defines a shared initial downlink BWP for RedCap UEs and non-RedCap UEs. The UE switches to a separate initial downlink BWP for RedCap UEs. The UE accesses the cell via the separate initial downlink BWP. The UE receives a configuration of an active downlink BWP for RedCap UEs. The UE determines whether to switch from the active downlink BWP to the shared initial BWP or the separate initial downlink BWP to obtain information such as updated system information, system measurements, and uplink configuration information.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects at least one of a first type of reference signal (RS) or a second type of RS within an active bandwidth part (BWP). The UE then derives uplink (UE) transmission timing and corresponding accuracy requirement, based on which type of RS was detected. The UE then transmits UE signals based on the derived UE transmission timing and the corresponding accuracy requirement.
