    摘要: A device includes at least a first and a second antenna array module. The first antenna array module serves a first frequency band, the first antenna array module having a first antenna array surface that is substantially perpendicular to a first boresight and oriented substantially parallel to a first surface of the device adjacent to the first antenna array module, the second antenna array module serves a second frequency band, the second antenna array module having a second antenna array surface that is substantially perpendicular to a second boresight and oriented at an angle relative to a second surface of the wireless communication device adjacent to the second antenna array module, and the device transmits an indication of a set of transmission configuration indicator (TCI) states for use in the first frequency band and the second frequency band, the set of TCI states being selected based on the angle.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, and a base station may receive, information related to multipath richness of a channel environment and information related to antenna module capabilities associated with the UE for at least a first frequency band and a second frequency band. The base station may transmit, and the UE may receive, information indicating a multiple input multiple output (MIMO) mode in which to operate one or more antenna modules of the UE based at least in part on the information related to the multipath richness of the channel environment, the antenna module capabilities associated with the UE, and respective cell loadings in the first frequency band and the second frequency band. Numerous other aspects are provided.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a polarization performance loss indication that is indicative of a loss in polarization performance based on transitioning from a first operating state associated with a first frequency range to a second operating state associated with a second frequency range, wherein the first operating state corresponds to a first antenna configuration and the second operating state corresponds to a second antenna configuration, wherein the first antenna configuration corresponds to a first antenna orientation and the second antenna configuration corresponds to a second antenna orientation. The UE may receive, from the network node, configuration information indicative of at least one communication parameter associated with the at least one antenna array and based on the polarization performance loss indication. Numerous other aspects are described.
