    摘要: A user equipment (UE) receives TCI state configurations for a plurality of signals, wherein a first state configuration comprises a first port for a first signal being quasi-co-located (QCL) to a second port of a second signal and a second state configuration comprises the second port of the second signal being QCL to a third port of a third signal and determines a TCI chain comprising the first, second and third signals so that channel measurements for each one of the first, second and third signals are applied to channel measurements for each other one of the first, second and third signals, wherein at least one of the first, second or third signals is an uplink (UL) signal.

    摘要: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a use equipment (UE) to determine, based on a transmission configuration indicator (TCI) state, a sensing beam to wirelessly communicate with a base station over a channel in an unlicensed spectrum. The UE can receive, using a receiving beam, control information including a TCI state, determine a sensing beam indicated by the TCI state included in the control information, sense a channel occupancy of the channel between the UE and the base station by performing Clear Channel Assessment using the sensing beam. Furthermore, the UE can determine, based on the channel occupancy, whether the channel is free to be utilized for communication by the UE using the sensing beam.

    摘要: Described is an apparatus of an Evolved Node-B (eNB). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to associate a first Beam Reference Signal (BRS) for a first Transmit (Tx) beam having a first beamwidth with one or more second BRSes for one or more respectively corresponding second Tx beams having a second beamwidth. The second circuitry may be operable to generate a first BRS transmission carrying the first BRS, and to generate one or more second BRS transmissions carrying the one or more respectively corresponding second BRSes. The third circuitry may be operable to provide information regarding the first BRS and the second BRSes to the second circuitry.
