    Abstract: The exemplary embodiments relate to determining which instance of control information is to be used for transmitter beam selection. A user equipment may receive a medium access control (MAC) control element (CE) that includes first control information associated with transmitter beam selection, transmit an acknowledgement (ACK) to the network in response to receiving the MAC CE and receive a downlink signal over a physical downlink control channel (PDCCH) that schedules an uplink transmission. The downlink signal is received prior to an expiration of a predetermined duration relative to transmitting the ACK and includes second control information associated with transmitter beam selection. The UE may also transmit an uplink signal based on the scheduled uplink transmission. The UE selects a transmitter beam for the uplink signal based on one of the first control information or the second control information.

    Abstract: A base station of a network configures a first search space having a first search space identification (SearchSpaceId) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceId) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

    Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.
