Abstract
A mobile communications system is described in which a mobile device is operable to communicate with base stations using a first radio technology and with other devices using a second radio technology. The mobile device maintains a control plane connection with a first base station and a user plane connection via a second base station. In case of an interference is detected due to concurrent use of the first and second radio technologies, the mobile device provides assistance information to the base stations, based on which the base stations alleviate the effects of the detected interference.
Claims6
A method performed by a user equipment (UE), the method comprising:
- communicating with a first base station and a second base station via a plurality of carriers using a first radio access technology;
- communicating with a wireless communication device using a second radio access technology;
- detecting in-device coexistence (IDC) interference corresponding to the second base station based on coexistence of the first radio access technology and the second radio access technology;
- transmitting, to the first base station, in a Radio Resource Control (RRC) message an IDC indication including information identifying a type of the second radio access technology;
- wherein the IDC interference is addressed based on allocation of at least one physical resource block (PRB) within one of the plurality of carriers and outside a frequency range of the second radio access technology.

A method performed by a first base station, the method comprising:
- communicating with a user equipment (UE) via at least one of a plurality of carriers using a first radio access technology, wherein the UE is configured to communicate with a second base station via at least one of the plurality of carriers using the first radio access technology and communicate with a wireless communication device using a second radio access technology;
- receiving, from the UE, an in-device-coexistence (IDC) indication in a Radio Resource Control (RRC) message, in a case where the UE detects an IDC interference corresponding to the second base station based on coexistence of the first radio access technology and the second radio access technology in the UE, the IDC indication including information identifying a type of the second radio access technology;
- and
- addressing the IDC interference by allocating at least one physical resource block (PRB) within one of the plurality of carriers and outside a frequency range of the second radio access technology.
