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： Systems and methods are provided for enabling different “bundling” methods for downlink transmissions and provide different interpretations of the acknowledgement/negative-acknowledgement bit. A user equipment is configured so that it commonly acknowledges all downlink transmission time intervals within a bundle so that if one packet is determined to be erroneous, all packets in that bundle will be retransmitted. Additionally, the systems and methods are implemented by allowing an interpretation to be applied to the uplink acknowledgement/negative-acknowledgement field such that the user equipment is able to divide bundled downlink packets into smaller windows in Long Term Evolution (LTE) Release 8 time division duplex (TDD) mode. In LTE Advanced (LTE-A) TDD mode, various embodiments provide bundling within the time domain, within the frequency domain, and within a hybrid time-frequency domain. Furthermore, enhanced channel selection methods are also provided in support of the above-mentioned bundling methods in accordance with various embodiments.

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 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.
