Abstract: A HARQ data reception scheme for a multiradio communication device is disclosed. The communication device operates multiple radio connections and monitors interference level caused to a target radio connection by at least one other radio connection operated in the communication device. A data packet and at least one retransmission data packet are received with the target radio connection. The utilization of the received data packet and the at least one received retransmission data packet in a hybrid automatic repeat request data reception is determined according to the interference level at the time instant associated with the reception of the corresponding data packet. Under high interference, the received data packet may be discarded, and detected and decoded data packets may be weighted for the HARQ combining according to the interference levels associated with the data packets.

Abstract: A method, terminal, and computer program are disclosed to reduce radio interference in a wireless communications device having a combination of a wireless telephone unit, such as a GSM cellular phone, and a short range wireless communications unit, such as a WLAN communications unit or a Bluetooth communications unit. An interference avoidance subsystem in the wireless communications device is connected between the GSM frequency hopping logic and the Bluetooth frequency hopping logic. Bluetooth frequency hopping information and time domain operation information are input from the Bluetooth frequency hopping logic to the interference avoidance subsystem. GSM frequency hopping information and time domain operation information are input from the GSM frequency hopping logic to the interference avoidance subsystem. The interference avoidance subsystem then uses this input data to calculate the interference probability between co-existing Bluetooth received signals and GSM transmitted signals.
