摘要: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

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: Methods and systems for operating a base station to reduce beam squinting include determining a lower bound on the number of directional beams used by the base station for millimeter wave wideband communications (e.g., based on operating conditions of the base station or wireless devices within the coverage area of the base station) and transmitting synchronization signal block (SSB) messages in an SSB Burst Set consistent with the determined lower bound on the number of directional beams used by the base station for millimeter wave wideband communications.

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.

摘要: An antenna system includes: a ground conductor; a substrate; a pair of planar dipole conductors disposed such that at least a portion of the substrate is disposed between the ground conductor and the pair of dipole conductors; a pair of energy couplers each electrically connected to a respective one of the pair of dipole conductors; and a pair of isolated lobes including electrically-conductive material. The pair of isolated lobes are electrically separate from the pair of dipole conductors and the pair of energy couplers, and disposed between the pair of dipole conductors and the ground conductor.
