Abstract: Embodiments include methods for a communication node configured with an antenna array having a plurality of antenna elements. Such methods include determining a link metric for a data transmission received or transmitted using a first portion of the antenna elements, and determining a first value for a first function of the link metric and of a performance target for the link metric. Such methods include, based on the first value, selectively updating the first portion and a second portion of the antenna elements by a first number. The second portion is disjoint from the first portion. Such methods include concurrently performing the following when the updated second portion includes at least one antenna element: receiving or transmitting one or more data transmissions using a first beam formed by the updated first portion; and scanning for reference signal transmissions using a second beam formed by the updated second portion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication that indicates a blockage event as a cause for a change in one or more of rank information or channel quality information, wherein the blockage event is associated with a differential signal power between a first polarization and a second polarization. The UE may receive, from the base station, a transmission based at least in part on the indication that indicates the blockage event as the cause for the change in one or more of the rank information or the channel quality information. Numerous other aspects are described.

Abstract: The present invention relates to a first network device (20; 51) for transmission of reference signal resources comprising an antenna arrangement (61) having at least two panel (62, 63) configured to generate beams (53) in different directions. The first network device (20; 51) comprises a control circuitry (210) configured to transmit, as part of performing a beam selection procedure with a second network device (30a; 52), a first reference signal resource in one or more beams from a first of the at least two panel, and a second reference signal resource in one or more beams from a second of the at least two panel. The one or more beams from the first of the two panels is different from the one or more beams from the second of the two panels, and the first reference signal resource is time-wise overlapping with the second reference signal resource when transmitted.

Abstract: There is provided mechanisms for signalling TCI states. A method is performed by a network node. The network node is configured to control transmission of reference signals from at least two TRPs. The method comprises signalling, towards user equipment is served by the network node, a sequence of TCI states defined for a reference signal burst in which the reference signals are to be transmitted from the TRPs. At least one of the TCI states in the sequence of TCI states is representative of one of the reference signals to be jointly transmitted on a beamform from a first TRP of the TRPs and on a beamform from a second TRP of the TRPs. The method comprises initiating transmission of the reference signal burst from the TRPs.

Abstract: An electronic device includes: a first pair of antennas having a first polarization along a first direction in a plane, where the first pair of antennas are spatially offset from each other along a second direction in the plane; and a second pair of antennas having a second polarization along the second direction, where the second pair of antennas are spatially offset from each other along the first direction. During operation, the electronic device may configure switching elements to: select the first pair of antennas and electrically couple the second pair of antennas to ground; or select the second pair of antennas and electrically couple the first pair of antennas to ground. Then, the electronic device may communicate a packet or a frame with a second electronic device via the selected first pair of antennas or the second pair of antennas.
