    摘要: A next-generation node B (gNB) configured for operation in a fifth-generation system (5GS) encode signalling for transmission to a user equipment (UE) indicating a Transmission Configuration Indication (TCI) state change to activate a new TCI state. A physical downlink control channel (PDCCH) is encoded in accordance with a highest aggregation level if the signalling indicating the TCI state change indicates activation of a new TCI state for the PDCCH. A physical downlink shared channel (PDSCH) is encoded in accordance with a lowest modulation and coding scheme (MCS) level if the signalling indicating the TCI state change indicates activation of a new TCI state for the PDSCH. After the TCI state change, reference signals (RS) are transmitted with a different spatial filter or different antenna ports demodulation of the PDCCH and PDSCH by the UE.

    摘要: Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.

    摘要: Embodiments of an apparatus of a user equipment (UE) configured for operation in a fifth-generation system (5GS) are described herein. The UE comprises first and second array antennas for transmission of mmWave signals including a sounding-reference signal (SRS). In response to decoding radio-resource configuration (RRC) signalling that indicates antenna switching for SRS, the UE initiates a countdown timer and transitions the second array antenna from a low-power state to an active state. If a downlink control information (DCI) indicating SRS antenna switching is not received while the countdown timer is active, the UE generates a command to transition the second array antenna to a low-power state upon expiration of the countdown timer.

    摘要: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for configuration of System frame number (SFN) and Frame Timing Difference (SFTD) measurement in an E-UTRA (Evolved Universal Terrestrial Radio Access)—NR Dual Connectivity (EN-DC) network, and an NE-DC network. Various embodiments describe how to configure and perform the SFTD measurement in the EN-DC or NE-DC network of various conditions to facilitate adequate SFTD measurements and improve measurement accuracy and system performance. Other embodiments may be described and claimed.

    摘要: An apparatus of a user equipment (UE) comprises one or more baseband processors to process a message received from a Fifth Generation (5G) NodeB (gNB) to perform one or more measurements in one or more target frequency layers, and for each of the one or more target frequency layers, to divide one or more other frequency layers into one of three categories comprising fully overlapped frequency layers, partially overlapped frequency layers, and non-overlapped frequency layers. The apparatus includes a memory to store the message.

    摘要: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.
