Abstract: Improved techniques of beam management in a HO situation include receiving, at a source node from a candidate target node after receiving a measurement report from a UE prior to completion of a HO, a repetition configuration of a channel state information reference signal (CSI-RS) resource index to be used by the UE for random access. When beam refinement occurs during HO, a candidate target cell for HO provides the UE with a repetition configuration of CSI-RS resource index that will be selected and used by the UE for random access to the target cell. When beam refinement occurs before HO, the candidate target cell of handover provides the UE (e.g. during the handover preparation phase in case of conditional HO (CHO)) with the repetition configuration of CSI-RS resource index (or indices) whose transmission(s) is repeated while the UE is served by the source cell and before executing a handover.

Abstract: A communication apparatus (101, 1500) comprising a plurality of antenna panels (1513a, 1513b, 1513c, 1513d) is described. The apparatus comprises means for determining (302) whether a chained network deployment of cells (103-108) exists along a path (102) of said apparatus; means for selecting (304), in case said determination is positive, a neighbor cell (104) expected along said path; means for selecting (305), in case said determination is positive, an antenna panel of said plurality of antenna panels as a function of an information representative of a direction of motion of said communication apparatus along said path; and means for detecting (306) said expected neighbor cell using said antenna panel.
Methods and base stations are also described.
