Abstract: Apparatuses, methods, and systems are disclosed for bandwidth part (“BWP”) and beam switching. One apparatus includes a transceiver and a processor that receives a first configuration, where the first configuration contains a mapping between a set of beams and a set of BWPs in a cell. The processor jointly triggers beam and BWP switching based on a switching indication and according to the first configuration. The processor then communicates, via the transceiver, with a radio access network (“RAN”) using a new beam and a new BWP in response to the beam and BWP switching.

Abstract: A radio chain arrangement comprising at least two levels of radio chain entities. Each of the levels of radio chain entities is associated with a respective frequency range encompassing at least one radio frequency band each. At least two radio chain entities of a lower level of radio chains are comprised in a radio chain entity of a next higher level. Each radio chain entity of the at least two levels of radio chain entities comprises a respective radio transceiver arrangement that is connected to at least a respective one of a number of antenna multiplexers. For all radio chain entities except a lowest level, the respective radio transceiver arrangement is connected to the antenna multiplexers via a splitter arrangement. An active antenna system comprising such radio chain arrangements and a method for its operation is also disclosed.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first user equipment (UE) may receive an active communication configuration between the first UE and a base station. The first UE may receive a UE cooperation configuration between at least the first UE and a second UE. The UE cooperation configuration may include a configuration for communicating messages between the base station and a set of antenna panels corresponding to at least the first UE and the second UE as a single entity. The UE cooperation configuration may include parameters associated with the second UE. The first UE may identify, from the set of antenna panels, an antenna panel for reception of a downlink message based on the UE cooperation configuration. The first UE may transmit a message to the base station, the second UE, or both in response to the downlink message.

Abstract: Various embodiments of the present disclosure provide a method for multi-antenna transmission. The method which may be performed by a communication device comprises determining first correlation information in response to interference to data on a first subset of multiple antenna branches of the communication device. The first correlation information may indicate at least correlation between the data on the first subset of the multiple antenna branches and data on a second subset of the multiple antenna branches which is not affected by interference. The method further comprises correcting the data on the first subset of the multiple antenna branches, based at least in part on the first correlation information.

Abstract: The present disclosure describes apparatuses and methods of performance-based antenna selection for user devices. In some aspects, a user device includes a transceiver having a first receiver, as well as second and third receivers. The transceiver is coupled to a first antenna to enable communication via the first antenna and the second receiver is coupled to the second antenna to enable reception via the second antenna. The third receiver is coupled to a third antenna to enable monitoring of performance of the third antenna. Based on a comparison of respective performance of the first antenna and the third antenna, the first antenna or third antenna is coupled the transceiver to enable subsequent communication. By monitoring and comparing respective performance of the antennas before antenna switching is implemented, a better-performing antenna of the two antennas can be selected for coupling to the transceiver without impacting communication performance.
