Abstract:
1. A method for operating a user equipment of a wireless network, comprising: making a determination as to whether an anchor carrier set should be changed, wherein the anchor carrier set includes one or more anchor carriers used by the user equipment to receive control signals transmitted from a base station; and making a request to the base station to change the anchor carrier set when it is determined that the anchor carrier set should be changed, wherein it is determined that the anchor carrier set should be changed when a reliability of a first carrier is greater than a reliability of a second carrier from a perspective of the user equipment, wherein the first carrier is currently not in the anchor carrier set and the second carrier is currently in the anchor carrier set, and wherein the act of making the request to the base station to change the anchor carrier set comprises: making a determination as to whether the first carrier meets a predetermined minimum reliability threshold when it is determined that the anchor carrier set should be changed; and making a request to the base station to include multiple carriers into the anchor carrier set when it is determined that the first carrier does not meet the predetermined minimum reliability threshold, wherein the first carrier is included in the anchor carrier set after the change.
