    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 multiple application time values for transmission configuration indication (TCI) state updates.

  • Publication number: 20240146487
    Abstract: The apparatus may be a UE configured to receive, from a network node, a switch indication for the UE to switch from being served by a first cell to being served by a second cell. The apparatus may further be configured to receive a transmission configuration indication (TCI) state indication that indicates a TCI state for the UE to use with the second cell, where a first time period between the switch indication and the TCI state indication is based on a relationship of the TCI state to one or more reference signals measured by the UE prior to receiving the switch indication. The apparatus may also be configured to communicate with the network node via the second cell and using the TCI state.

  • Publication number: 20240137884
    Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may identify one or more measurement parameters to use for input in a machine learning (ML) model. In some cases, the measurement parameters may include reference signal received power measurements or a past set of timing advance (TA) values for a specific node. The UE may predict the TA based on inputting the measurement parameters into the ML model. The UE may transmit an uplink communication from the UE to a network entity using the TA predicted from the ML model. In some examples, the UE may transmit a capability report to indicate that the UE may support autonomous update of the TA based on the predictions of the TA values produced from the ML model.

  • Patent number: 11956182
    Abstract: Aspects of the present disclosure provide techniques for configuring multi-beam full-duplex communication that allows a device (e.g., user equipment (UE) or base station) to contemporaneously perform both uplink and downlink communication over the same frequency band. Because of the full duplex communication capability provided by the present disclosure, the NR system may achieve reduced latency and improved spectrum and resource efficiency, thereby accommodating a growing demands for the wireless communication. The full duplex communication capability may be achieved by implementing downlink control information (DCI) format that specifies to the UE the beam assignments for contemporaneous transmission (Tx) and reception (Rx).

  • Publication number: 20240113844
    Abstract: In a unified transmission configuration indicator (TCI) framework, certain channels are preconfigured to use a fixed number of TCI states. However, these preconfigured channels are not currently updated when the number of TCI states dynamically change during a switch between single and multiple transmission and reception point (TRP) modes. To alleviate this problem, a user equipment (UE) may receive downlink control information (DCI) indicating a first number of TCI states and, prior to the DCI, downlink information indicating a second number of TCI states, detect a switch between the multiple TRP (mTRP) and single TRP (sTRP) modes based on the first number of TCI states being different than the second number of TCI states, and communicate in a channel configured to use a selected TCI state associated with the first number of TCI states using a predefined rule based on the switch between the mTRP and sTRP modes.

Whether a component carrier is included in the list or whether a beam failure detection reference signal set of the one or more beam failure detection reference signal sets is applicable to the component carrier, or both, may be based on whether the component carrier is of a first type configured for a single beam failure detection reference signal set or is of a second type configured for multiple beam failure detection reference signal sets. The UE may monitor one or more component carriers included in the list for beam failure using the one or more indicated beam failure detection reference signal sets.

  • Patent number: 11943795
    Abstract: Wireless communications systems may support identification or determination of a common default beam for a component carrier (CC) group (e.g., such that all CCs of a CC group may be associated with a same default beam). For example, a CC group may be configured or established to include one or more CCs (e.g., for carrier aggregation), where each CC group may share a same analog beamformer. As such, a beam (e.g., a default uplink/downlink beam) may be established as default or common across CCs of a CC group (e.g., versus default beams being configured or established for individual CCs). Such an established default beam of a CC group (e.g., a default beam common to all CCs of a CC group) may include or refer to a default downlink shared channel beam, a default sounding reference signal (SRS) beam, a default downlink control channel beam, etc.

  • Publication number: 20240089977
    Abstract: This disclosure provides systems, methods, and apparatuses that enable abase station (BS) to transmit downlink control information (DCI) without downlink data to indicate a transmission configuration indicator (TCI). In one aspect, a user equipment (UE) may transmit a capability indication associated with whether the UE can receive DCI with a TCI and without a data assignment. The UE may receive DCI with one or more configured fields and without downlink data and may interpret the DCI, based on the one or more configured fields, to identify a TCI. The TCI may be a Type 1 beam indication or another type of beam indication. The DCI may C be a DCI format 1_1 or 1_2 or another DCI format, such as DCI format 1_0 or a DCI scheduling an uplink configuration, among other CN examples, and may indicate another configuration with the TCI.
