    摘要： A scrambling sequence is initialized using at least a cell identifier and an offset, and a physical downlink control information DCI is sent to a user equipment which indicates the offset. In more particular embodiments a user equipment-specific reference signal UE-RS is scrambled using the initialized scrambling sequence, and the scrambled UE-RS is sent to the UE for demodulating a downlink shared channel (PDSCH). In another exemplary embodiment the generated UE-RS is sent in a pilot part of a subframe transmission associated with the PDSCH and is for demodulating at least a data part of that subframe transmission. In a specific embodiment from the UE side, the UE receives the UE-RS and the DCI which indicates the offset, descrambles the UE-RS using a scrambling sequence that is initialized using a cell identifier and the indicated offset; and demodulates the PDSCH using the de-scrambled UE-RS.

    摘要： It is determined that there are X uplink control channel resources available for uplink signaling. Each of those X uplink control channel resources are sub-channelized into a plurality of sub-channels that each defines a unique time instant or point in time. For each of Y units of control information there is selected a unique combination of one of the sub-channels and a modulation (X and Y are each integers greater than one). The Y units of control information are sent on the X uplink control channel resources according to the respectively selected combinations. By example the uplink resources may be an ACK/NAK/DTX bit on a of one of the sub-channels and a modulation PUCCH. In one example the sub-channels are individual slots of a PUCCH. In another example the sub-channels are the reference-signal part and the data part of a single PUCCH slot.
