摘要

A base station for a mobile telecommunications system has circuitry, which is configured to communicate with at least one user equipment and at least another base station. The circuitry is further configured to configure a radio resource control message for radio resource control diversity, and transmit the configured radio resource control message to the user equipment or to receive a configured radio resource control message from the user equipment and the at least another base station.

說明書

The circuitry may be further configured to turn on/off the radio resource control diversity, based on the user equipment to which the configured radio resource control message is transmitted. For instance, the UE may turn on RRC diversity, if it wants to establish an RRC connection, in cases where the UE is located at a boundary of a serving base station, or the like.

The circuitry may be further configured to transmit an instruction message to the user equipment for turning on/off radio resource control diversity or for turning on/off the radio resource control diversity for specific radio resource control messages, such that the UE may turn on/off the RRC diversity generally or for specific radio resource control messages.

Hence, more generally, the radio resource control diversity may also be turned on/off for specific radio resource control messages such that, for example, for specific radio resource control messages radio resource control diversity is used and for others not.

The radio resource control diversity may be initiated, based on an uplink reference signal measurement, wherein the radio resource control diversity may be performed for a downlink communication or an uplink communication. The circuitry may be further configured to configure the user equipment for sending at least one of feedback signals and uplink reference signals, e.g. for performing uplink reference signal measurement. The circuitry may be further configured to define a radio resource control configuration, based on the received at least one of feedback signals and uplink reference signals.

The radio resource control diversity may be initiated, based on a downlink reference signal measurement, wherein the radio resource control diversity is performed for an uplink communication or a downlink communication.
