摘要

In one aspect, a network (e.g., a TRP) (150) uses handover triggering information to detect whether a handover triggering condition is present before a radio link fails, and initiates a handover upon detecting the handover triggering condition. In another aspect, a target TRP (152) is provided with beam generating information that enables the target TRP (152) to produce a high-gain beam for use in communicating with a UE (101) without having to perform a beam refinement procedure.

說明書

FIG. 7 is a diagram showing functional units of TRP 150 according to some embodiments. As shown in FIG. 7, the TRP 150 may include: a first obtaining 702 unit for obtaining first handover triggering information identifying a first handover triggering condition, the first handover triggering information comprising first beam information indicating a first set of beam characteristics; a communicating unit 704 for communicating with a user equipment, UE, using a high-gain beam having a second set of beam characteristics; a second obtaining unit 706 for obtaining second beam information indicating the second set of beam characteristics; a determining unit 708 for determining whether the first handover triggering condition is present (e.g., determining whether the second set of beam characteristics of the high-gain beam that is being used by the source TRP to communicate with the UE matches the first set of beam characteristics); and a handover unit 710 configured such that, as a result of the determining unit 708 determining that the first handover triggering condition is present, the handover unit initiates a handover of the UE from the source TRP to the target TRP.
