Abstract

UE-assisted management of advanced radio link feature in a wireless communication network may include a network entity determining that a mobile entity is capable of communicating with one or more base stations using a set of radio link configurations, receiving a request from the mobile entity to restrict use of at least one of the radio link configurations, and restricting use of the at least one of the radio link configurations for communicating with the mobile entity, based on the request. The request may indicate a reason for the restriction, and the network entity may determine whether to restrict based on the reason. Once a radio link configuration is restricted, it may similarly be unrestricted based on a subsequent UE request, or based on expiration of a time period.
