Abstract

The present disclosure pertains to a user equipment for a mobile telecommunications system, which has a circuitry configured to communicate with a new radio base station and a LTE base station. The circuitry is further configured to: perform simultaneous uplink communication with the LTE base station and the new radio base station; detect an overheating situation; and transmit capability information in response to detecting the overheating situation.

First claim

The invention claimed is:

1. A user equipment for a mobile telecommunications system comprising circuitry configured to communicate with a new radio base station and a LTE base station, wherein the circuitry is further configured to:
perform simultaneous uplink communication with the LTE base station and the new radio base station;
compare a combination of a new radio uplink band and a LTE uplink band to a predefined combination;
on condition that the combination of the new radio uplink band and the LTE uplink band equals the predefined combination, detect an overheating situation; and
transmit capability information including maximum capability of the user equipment and whether or not the overheating situation is detected based on the comparison of the combination to the predefined combination, wherein the capability information includes a temporal reduced capability of the user equipment that indicates an adjustment of an uplink configuration, the adjustment including at least one of: separate LTE and new radio (NR) uplink bands, time division multiplexing uplink sharing of a same frequency for LTE and NR, band, no NR support for uplink and downlink, and simultaneous uplink for LTE and NR bands.

2. The user equipment of claim 1 , wherein the circuitry is further configured to detect the overheating situation based on a decoding error.

3. The user equipment of claim 1 , wherein the circuitry is further configured to detect the overheating situation based on a signal strength of a reference signal.

4. The user equipment of claim 1 , wherein the circuitry is further configured to detect the overheating situation based on a temperature measurement of a receiver of the circuitry.

5. The user equipment of claim 1 , wherein the circuitry is further configured to detect the overheating situation based on the simultaneous uplink communication with the LTE base station and the new radio base station.

6. The user equipment of claim 1 , wherein the circuitry is further configured to detect the overheating situation based on history information indicating a previous overheating situation.

7. The user equipment of claim 1 , wherein the capability information is transmitted based on an assistance information signaling procedure.

8. The user equipment of claim 1 , wherein the capability information indicates the overheating situation.

9. The user equipment of claim 8 , wherein the capability information indicates a combination of the new radio uplink band and the LTE uplink band.

10. The user equipment of claim 1 , wherein the capability information indicates a capability of the user equipment, based on the detected overheating situation.

11. A base station for a mobile telecommunications system comprising circuitry configured to communicate with at least one user equipment, the base station being one of a new radio base station and a LTE base station, wherein the circuitry is further configured to:
receive capability information from the at least one user equipment, wherein the capability information is transmitted by the at least one user equipment that performs simultaneous uplink communication with the LTE base station and the new radio base station,
compare a combination of a new radio uplink band and a LTE uplink band to a predefined combination,
wherein the capability information includes maximum capability of the user equipment and, on condition that the combination of the new radio uplink band and the LTE uplink band equals the predefined combination, detect an overheating situation based on the comparison of the combination to the predefined combination, and
adjust an uplink configuration for the at least one user equipment, based on the received capability information including at least one of: providing separate LTE and new radio (NR) uplink bands, providing time division multiplexing uplink sharing of a same frequency for LTE and NR, band, providing no NR support for uplink and downlink, and providing simultaneous uplink for LTE and NR bands.

12. A method for determining capability information of a user equipment for a mobile telecommunications system configured to communicate with a new radio base station and a LTE base station, the method comprising:
performing simultaneous uplink communication with the LTE base station and the new radio base station;
comparing a combination of a new radio uplink band and a LTE uplink band to a predefined combination;
on condition that the combination of the new radio uplink band and the LTE uplink band equals the predefined combination, detecting an overheating situation; and
transmitting capability information in response to detecting the overheating situation, wherein the capability information includes maximum capability for the user equipment and whether or not the overheating situation is detected based on the comparison of the combination to the predefined combination; and
adjusting an uplink configuration for the user equipment, based on the received capability information, including at least one of: providing separate LTE and new radio (NR) uplink bands, providing time division multiplexing uplink sharing of a same frequency for LTE and NR, band, providing no NR support for uplink and downlink, and providing simultaneous uplink for LTE and NR bands.
