  • Patent number: 11902802
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a user equipment (UE), configuration information for both a first set of reference signals for a first beam sweeping procedure and a second set of reference signals for a second beam sweeping procedure. The UE may receive the first set of reference signals according to the configuration information, and may transmit a channel state information (CSI) report to the base station based on the received reference signals. After transmitting the CSI report, both the base station and the UE may autonomously update a transmission configuration indicator (TCI) state based on the CSI report (e.g., using a preferred transmit beam indicated in the CSI report). The base station may transmit on the preferred transmit beam, and the UE may receive on various candidate receive beams, the second set of reference signals.

  • Publication number: 20240048349
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

  • Publication number: 20240049242
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for efficiently indicating transmission configuration indication (TCI) states to a user equipment (UE) for communicating with one or more transmission and reception points (TRPs). A first TRP may transmit an indication to a UE of a first TCI state for communicating with a second TRP. The first TCI state may be selected from a set of TCI states activated at the UE for communicating with the second TRP. The indication, from the first TRP, of the first TCI state, for communicating with the second TRP, may be referred to as a cross-TRP TCI indication. The UE may receive the indication of the first TCI state from the first TRP and may communicate with the second TRP according to the first TCI state.

    Abstract: Embodiments of this application provide a filtering structure and an electronic device. In the filtering structure, an intermediate assembly is disposed between a chip and a circuit board, a first filtering assembly is disposed inside the intermediate assembly, and at least a part of a second filtering assembly is disposed on a surface that is of the circuit board and that is away from the intermediate assembly, so that the first filtering assembly is close to the chip. This shortens a filtering path of the chip, improves a dynamic response capability of the chip, and therefore improves an overall filtering capability.

  • Patent number: 11895596
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform path-loss estimation to support uplink transmit power control. The UE may perform path-loss estimations on path-loss reference signals configured by a base station. In some cases, the base station may update (e.g., activate, deactivate, or both) particular path-loss reference signals using a medium access control (MAC) control element (CE). The UE may determine which path-loss reference signal or signals to use for path-loss estimation based on one or more techniques. For example, the UE may filter path-loss measurements over a time duration or may use a single, unfiltered path-loss measurement for path-loss estimation. Additionally or alternatively, the UE may receive deactivated path-loss reference signals (e.g., for a set amount of time or for any amount of time) or may refrain from receiving deactivated path-loss reference signals.

  • Publication number: 20240039679
    Abstract: A user equipment (UE) may use a resource configuration to determine whether to transmit or receive on a particular sub-band during a given communication period (e.g., a time slot or a symbol duration). In some examples, a network entity provides a bit map to a UE where the bit map indicates how sub-bands for a given communication period are allocated for full-duplex transmissions. The UE may then determine, based on the bit map, whether to transmit or receive on a particular sub-band. In some examples, a network entity provides a resource configuration to a UE where the resource configuration indicates how half-duplex transmissions and full-duplex transmissions are configured over a period of time. In this case, the UE may be configured by a defined rule to determine, based on the resource configuration, whether to transmit or receive on a particular sub-band.

  • Publication number: 20240040522
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multiplexing and prioritization techniques for uplink signaling and non-serving cell synchronization signals. In some aspects, a user equipment (UE) and a network entity may support a prioritization rule according to which the UE and the network entity may enable uplink multiplexing with a set of non-serving cell synchronization signal blocks (SSBs). For example, an uplink signal and a set of non-serving cell SSBs may be scheduled for the UE and may at least partially overlap in time and the UE may prioritize one of the uplink signal or the set of non-serving cell SSBs in accordance with the prioritization rule. The prioritization rule may be associated with a scheduling offset of the uplink signal or may be associated with whether the set of non-serving cell SSBs are indicated for measurement at the UE.
