    摘要: The specification and drawings present a new method, system, apparatus and software product for locating synchronization channels (SCH) in a downlink which are received by a user equipment (UE), such that the downlink synchronization channels are transparent to shared channel users (or UE) which can be used, e.g., in evolving and future systems such as EUTRAN, 4G, 3GPP2, etc. The synchronization channels are arranged so that they are transparent to the UE in a normal active operation state. For that, the resources given to the SCH are chosen to be one or more allocatable resources (resource units) in a sub-frame or in a plurality of sub-frames. In an allocation table, these resources may not be allocated to the UE and in the active state the UE sees that and discards these resources just as it discards any other resource that is not allocated to it.

    摘要: 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.
