DYNAMIC ANTENNA SELECTION AND BEAM STEERING
A method performed by a user equipment (UE) configured with a plurality of antenna panels. Each antenna panel is configured to beamform over a millimeter wave (mmWave) frequency band. The method includes identifying a predetermined condition corresponding to a first antenna panel of the plurality of antenna panels, selecting a second antenna panel of the plurality of antenna panels based on identifying the predetermined condition corresponding to the first antenna panel and transmitting a beam via the second antenna panel based on the selection.

Techniques for assisted beam refinement
Techniques are described herein for a beam refinement procedure between a first communications device (e.g., base station) and a second communications device (e.g., user equipment (UE)) that uses long-term feedback information from the second communications device to maintain a beam pair link established for a downlink connection. The second communications device may transmit long-term feedback information to the first communications device in response to a request or a trigger event occurring. The long-term feedback information may be sensor information measured by the second communications device or uplink training symbols. The first communications device may localize a beam search of the beam refinement procedure using the long-term feedback information. The localized beam search may be an example of a device-specific search. The first communications device may also generate a long-term map of channel conditions based on the long-term feedback data. The long-term map may also be used to localize the search.

Activation/deactivation of semi-persistent channel state information report
A wireless device receives a medium access control (MAC) control element (CE) identified by a MAC subheader. The MAC CE comprises: a first field associated with a first cell of a plurality of cells, wherein the first field being set to a first value indicates a command of activation/deactivation of SP CSI reporting on the first cell is present; a semi-persistent channel state information (SP CSI) reporting activation/deactivation indicator; and a SP CSI report trigger field indicating a SP CSI reporting of a plurality of SP CSI reporting on the first cell; In response to the SP CSI reporting activation/deactivation indicator indicating an activation of the SP CSI reporting on the first cell, a SP CSI report for the first cell is transmitted via an uplink control channel.

WIRELESS COMMUNICATION DEVICE FOR CORRECTING OFFSET BETWEEN BASE STATION AND WIRELESS COMMUNICATION DEVICE AND METHOD OF OPERATING THE SAME
A method of operating a wireless communication device for correcting an offset between a base station and the wireless communication device includes determining whether to perform offset correction using a first target synchronization signal block (SSB) to generate a determination result in response to changing a selected reception beam from a first reception beam to a second reception beam in an SSB period, the first target SSB being received via the second reception beam, and performing the offset correction on the second reception beam using at least one first neighbor SSB based on the determination result, the at least one first neighbor SSB being received via the first reception beam.
Determining a position of a wireless device
It is presented a method for determining a position of a wireless device within a single radio cell served by a plurality of remote radio heads. The method is performed in a position determination node and comprises the steps of: receiving a measured power signature comprising at least two, in time separated, power measurement values of a downlink signal, the measured power signature originating from the wireless device; comparing the measured power signature with a set of reference power signatures, wherein each one of the plurality of remote radio heads is associated with a reference power signature and the reference power signatures differ for at least two of the plurality of remote radio heads; and determining a position in that the wireless device is in the vicinity of one of the at least one remote radio head whose reference power signature best matches the measured power signature.
