    Abstract: Apparatus and method are provided to determine the starting subframe of a data channel. In one novel aspect, the UE monitors one or more control channel candidates, which at least one of the control channel candidate occupies a plurality of the subframes. The UE detects a control channel intended for the UE, decodes the control channel and determines the starting subframe of the data channel based on the control channel and a known gap. The UE further obtains a subframe indicator from the control channel. The subframe indicator signals either the number of subframes between the starting subframe of the data channel and the starting subframe of the control channel, or the number of subframes of the control channel, or the starting subframe of the data channel. In one embodiment, predefined rule can be applied to the subframe indicator to determining the starting subframe of the data channel.

    Abstract: A method for a receiver to cancel or suppress co-channel interference with network assistance is provided. The method comprises deriving a first set of parameters related to interfering signals in a mobile communication network; receiving a second set of parameters related to the interfering signals from the network; and cancelling the contribution of interfering signals from the received signal based on the combination of the first set and second set of parameters. In one embodiment, scrambling rules and resource block allocation information are signaled to the victim UE to facilitate Codeword-Level Interference Cancellation (CWIC). While the scrambling rule for control channel is based on UE-specific identity, the scrambling rule for data channel is based on cell-specific identity or other network-configurable identity to facilitate CWIC. In addition, RA-allocation information are signaled to the victim UE in an efficient way.

    Abstract: To support the new characteristics where FDD carriers and TDD carriers provide different services with different QoS or with different coverage or with different mobility robustness, UE enhancements of FDD-TDD network are proposed. In one embodiment, a dual mode UE in idle mode camps on a source cell and determines a target cell based on the cn domain and/or additional paging information contained in an enhanced paging message. In another embodiment, a dual mode UE may establish an RRC connection with a source cell with TDD carrier, and later is handover or redirected to a target cell supporting voice over IMS. The handover or redirection is based on the cn domain and/or the additional paging information contained in the enhanced paging message.

    Abstract: A method of small cell discovery and RSRP/RSRQ measurements in OFDM/OFDMA systems is proposed. A discovery reference signal (DRS) with low transmission frequency is introduced to support small cell detection within a short time, multiple small cell discovery, and accurate measurement of multiple small cells. The DRS consists of one or multiple reference signal types with the functionalities including timing and frequency synchronization, cell detection, RSRP/RSSI/RSRQ measurements, and interference mitigation. RE muting is configured for the DRS to reduce interference level from data to DRS for discovery and RSRP/RSRQ measurements for small cells.

    Abstract: A method of interference cancellation is proposed. A UE obtains configuration information of a data transmission from a neighboring cell via an interference channel in a mobile communication network. The UE receives radio signals on a set of data resource elements as determined based on the obtained configuration information. The UE then estimates the interference channel corresponding to the data transmission from the neighboring cell based on the received radio signals on the set of data resource elements. Finally, the UE cancels the data transmission from the neighboring cell based on the estimated interference channel.
