A method comprising: obtaining, by a first radio module, traffic or scheduling information of a second radio module co-located with the first radio module in a wireless communication device; determining a desired time-division multiplexing, TDM, pattern for the first radio module based on the traffic or scheduling information to mitigate in-device coexistence, IDC, interference with the second radio module; transmitting to and receiving at a base station in a wireless communication system TDM coexistence pattern information based on the desired TDM pattern, wherein the TDM coexistence pattern information comprises a recommended TDM pattern periodicity (T longDRX-Cycle), a scheduling period (T onDuration), a time offset (T offset) between a first DRX cycle start point and an incoming signal of the second radio module; determining at the base station a set of configuration parameters for the first radio module based on the TDM coexistence pattern information to mitigate in-device coexistence, IDC, interference between the first radio module and the second radio module, characterized in that the configuration parameters are discontinuous reception, DRX, configuration parameters, defined in long-term evolution, LTE, 3GPP Release 8/9 standards, and in that the method further comprises: transmitting to and receiving at a base station an IDC interference indication; and restricting flexible extension to restrict an ON duration in each DRX cycle to 60ms to reduce collision probability between the first and the second radio modules. obtaining, by a first radio module, traffic or scheduling information of a second radio module co-located with the first radio module in a wireless communication device; determining a desired time-division multiplexing, TDM, pattern for the first radio module based on the traffic or scheduling information to mitigate in-device coexistence, IDC, interference with the second radio module; transmitting to and receiving at a base station in a wireless communication system TDM coexistence pattern information based on the desired TDM pattern, wherein the TDM coexistence pattern information comprises a recommended TDM pattern periodicity (T longDRX-Cycle), a scheduling period (T onDuration), a time offset (T offset) between a first DRX cycle start point and an incoming signal of the second radio module; determining at the base station a set of configuration parameters for the first radio module based on the TDM coexistence pattern information to mitigate in-device coexistence, IDC, interference between the first radio module and the second radio module, characterized in that the configuration parameters are discontinuous reception, DRX, configuration parameters, defined in long-term evolution, LTE, 3GPP Release 8/9 standards, and in that the method further comprises: transmitting to and receiving at a base station an IDC interference indication; and restricting flexible extension to restrict an ON duration in each DRX cycle to 60ms to reduce collision probability between the first and the second radio modules. transmitting to and receiving at a base station an IDC interference indication; and restricting flexible extension to restrict an ON duration in each DRX cycle to 60ms to reduce collision probability between the first and the second radio modules.
