The present application is based on PCT filing PCT/EP2017/070521, filed Aug. 11, 2017, and claims priority to 16183716.6, filed in the European Patent Office on Aug. 11, 2016, the entire contents of each of which are being incorporated herein by reference.
The present disclosure generally pertains to a base station, user equipment and mobile telecommunications system method which employ radio resource control diversity.
Several generations of mobile telecommunications systems are known, e.g. the third generation (“3G”), which is based on the International Mobile Telecommunications-2000 (IMT-2000) specifications, the fourth generation (“4G”), which provides capabilities as defined in the International Mobile Telecommunications-Advanced Standard (IMT-Advanced Standard), and the current fifth generation (“5G”), which is under development and which might be put into practice in the year 2020.
A candidate for providing the requirements of 5G is the so-called Long Term Evolution (“LTE”), which is a wireless communications technology allowing high-speed data communications for mobile phones and data terminals and which is already used for 4G mobile telecommunications systems. Other candidates for meeting the 5G requirements are termed New Radio (NR) Access Technology Systems (NR). An NR can be based on LTE technology, just as LTE was based on previous generations of mobile communications technology.

The invention claimed is:1. A base station for a mobile telecommunications system comprising:circuitry configured to communicate with at least one user equipment and at least another base station, wherein the circuitry is further configured to configure a radio resource control message for radio resource control diversity; transmit the configured radio resource control message to the at least one user equipment or to receive a configured radio resource control message from the at least one user equipment and the at least another base station; perform control to turn on or off the radio resource control diversity based on a type of the radio resource control message by turning on the radio resource control diversity for a first type of radio resource control message, and turning off the radio resource control diversity for a second type of radio resource control message, which is different from the first type of radio resource control message; wherein the turning on or off is based on the user equipment to which the configured radio resource control message is transmitted; wherein the first type of radio resource control message and the second type of radio resource control message are associated with a radio resource control connection suspend and radio resource control connection resume. 2. The base station of claim 1 , wherein the first type of radio resource control message and the second type of radio resource control messages are associated with at least one of: radio resource control establishment or radio resource control re-establishment. 3. The base station of claim 1 , wherein the circuitry is further configured to perform control to turn on or off the radio resource control diversity. 4. The base station of claim 1 , wherein radio resource control diversity is initiated, based on an uplink reference signal measurement, and wherein the radio resource control diversity is performed for a downlink communication or an uplink communication. 5. The base station of claim 4 , wherein the circuitry is further configured to configure the user equipment for sending at least one of feedback signals and uplink reference signals. 6. The base station of claim 5 , wherein the circuitry is further configured to define a radio resource control configuration, based on the received at least one of feedback signals and uplink reference signals. 7. The base station of claim 1 , wherein the radio resource control diversity is initiated, based on a downlink reference signal measurement, and wherein the radio resource control diversity is performed for an uplink communication or a downlink communication. 8. The base station of claim 1 , wherein the circuitry is further configured to:turn on the radio resource control diversity for a radio resource control message based on whether the radio resource control message is associated with at least a first one of handover, radio resource control establishment, radio resource control re-establishment, radio resource control connection suspend and radio resource control connection resume; and turn off the radio resource control diversity for a radio resource control message based on whether the radio resource control message is associated with at least another of handover, radio resource control establishment, radio resource control re-establishment, radio resource control connection suspend and radio resource control connection resume. 9. A user equipment for a mobile telecommunications system comprising:circuitry configured for radio resource control diversity communication, wherein the circuitry is further configured to receive or transmit at least two radio resource control messages, which are configured for radio resource control diversity communication; control turning on or off the radio resource diversity communication based on a type of the at least two radio resource control messages by turning turn on the radio resource control diversity communication for a first type of radio resource control message, and turning off the radio resource control diversity communication for a second type of radio resource control message, which is different from the first type of radio resource control message wherein the circuitry is further configured to transmit a radio resource control message including at least one of a target radio resource control receiver identifier and additional radio resource control receiver identifier; and wherein the acknowledgment message includes at least one of an indication about the type of received radio resource control messages and an indication about the origin of the received radio resource control messages. 10. The user equipment of claim 9 , wherein the circuitry is further configured to control turning on or off the radio resource control diversity communication, based on an instruction message received from a base station. 11. The user equipment of claim 9 , wherein the circuitry is further configured to control turning on or off the radio resource control diversity communication, based on a radio resource control establishment. 12. The user equipment of claim 9 , wherein the circuitry is further configured to control turning on or off the radio resource control diversity communication if the user equipment is located at a cell boundary. 13. The user equipment of claim 9 , wherein the circuitry is further configured to control turning on or off the radio resource control diversity communication if a radio link failure is detected. 14. The user equipment of claim 9 , wherein the circuitry is further configured to receive the at least two radio resource control messages based on a radio resource control diversity set received from a base station. 15. The user equipment of claim 9 , wherein the circuitry is further configured to transmit an acknowledgment message in response to receiving the radio resource control messages.
