摘要： Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may be configured for carrier aggregation (CA) in which a plurality of component carriers (CCs) are aggregated. The UE may determine a mapping of the CCs to a plurality of antenna panels for downlink reception, wherein a subset of the CCs are mapped to each antenna panel. The UE may transmit, to the gNB, radio resource control (RRC) signaling that indicates information related to the mapping. The gNB may, based at least partly on the mapping, determine, for each CC: a first scheduled time period for transmit beam refinement, and a second scheduled time period for receive beam refinement at the UE.

摘要： Aspects of the subject disclosure may include, for example, receiving, by a network element of a distributed antenna system, a reference signal, a control channel and a first modulated signal at a first carrier frequency, the first modulated signal including first communications data provided by a base station and directed to a mobile communication device. The instructions in the control channel direct the network element of the distributed antenna system to convert the first modulated signal at the first carrier frequency to the first modulated signal in a first spectral segment. The reference signal is received at an out of band frequency relative to the control channel. Other embodiments are disclosed.

摘要： Techniques for performing reference signal measurement filtering in systems that support multi-beam operation are provided. A method for wireless communication by a base station (BS) includes determining at least one beam configuration for measuring reference signals transmitted from the apparatus, and signaling the beam configuration(s) to at least one user equipment (UE). A method for wireless communication by a UE includes receiving, from a BS, at least one beam configuration for measuring reference signals from the BS, and performing a measurement procedure for reference signals received from the BS based at least in part on the beam configuration(s).
