  • Methods, Systems, and Apparatuses for Beam Management
    Publication number: 20240292422
    Abstract: Wireless communications are described. A base station may send control information for scheduling data to be transmitted to the wireless device via a downlink. The control information may comprise one or more indications of wireless resources to be used by the wireless device to receive the data. The wireless device may receive the data based on one or more determinations/conditions, such as satisfying a time offset (e.g., between reception of the downlink information and a scheduled transmission of the data), whether a control resource set is configured to indicate a transmission configuration state, and/or whether the control information indicates a transmission configuration state.
