Abstract: A method for determining synchronization of uplink timing in a machine type communication (MTC) system comprising a machine type communication device (MTCD) and a network element is disclosed that takes advantage of the MTCD being at a fixed location relative to the network element. The method includes receiving at the MTCD an uplink timing adjustment value from the network element and storing the uplink timing adjustment value at the MTCD. The MTCD then uses the stored uplink timing adjustment value from a previous uplink transmission for synchronizing uplink timing for a subsequent uplink transmission from the MTCD to the network element even following a period of inactivity of the MTCD, or expiration of any existing maximum uplink timing alignment period permitted for use of the timing adjustment value by the MTCD, or MTCD clock drift.

Abstract: Embodiments are provided for adaptive user equipment (UE) cooperation mode selection in wireless networks. An adaptive UE cooperation strategy is implemented, which adaptively switches between a Decode-and-Forward (D&F) mode and a soft UE combining mode that involves combining, at the TUE, signals from multiple cooperating UEs (CUEs). A method by a network component includes obtaining access link qualities for links between a base station and a plurality of CUEs for a target UE (TUE). A UE cooperation mode or a hybrid UE cooperation mode is then selected from a plurality of supported UE cooperation modes according to the access link qualities of the CUEs. At least one of the CUEs is then instructed to cooperate in forwarding the signals to the TUE using the selected UE cooperation mode. The CUEs can dynamically opt out of the UE cooperation according to the channel quality of the CUEs or TUE.
