Description

Method, device, base station and terminal that a kind of descending scheduling is indicated

Technical field

The present invention relates to wireless technical field, more particularly to a kind of method of descending scheduling instruction, device, base Stand and terminal.

Background technology

In the tenth version of Long Term Evolution (LTE, Long Term Evolution), carrier wave is introduced Polymerizable functional, control information (channel status reporting, hybrid automatic repeat-request, the scheduling of 1/ layer 2 layers of layer Request) will be positioned at physical uplink control channel (PUCCH, Physical Uplink Control Channel transmit on the ascending resource for being specifically used to transmit 1/ layer of 2 control information of uplink layer on).Wherein, Two kinds of forms are introduced for carrier aggregation and supports the PUCCH feedback under carrier aggregation：

The first is form 1b (Format 1b), and which can support most 2 Serving cell (serving The feedback of carrier aggregation cell), the correct transmission instruction of most carryings 4 or erroneous transmissions instruction (A/N, ACK/NACK) feedback bits (bit)；

The first is form 3 (Format 3), and which can support the carrier aggregation of most 5 serving cell Under hybrid automatic repeat-request (HARQ, Hybrid Automatic Repeat reQuest) feedback, it is right At most need to feed back the ACK/NACK of 10bit in FDD (FDD, Frequency Division Dual) Information；For time division duplex (TDD, Time Division Duplexing) at most feedback 20bit's ACK/NACK bit informations, if multiple descending sub frames one sub-frame of uplink of correspondence, and would need feedback When ACK/NACK bit numbers are more than 20, then the 2 of the descending sub frame of each serving cell code word is needed The space binding done by ACK/NACK bits.

Which kind of specifically fed back using form as terminal, by high-rise configuration.Under the scene of carrier aggregation, User can only feed back a PUCCH in main carrier (Pcell).

Existing protocol supports the A/N number of bits of feedback of carrier aggregation to determine, the determination mode of feedback format with And process of feedback is as follows：

The first step, base station are the carrier number and specific carrier wave that terminal configures polymerization, and the configuration is by wireless money Source control (RRC, Radio Resource Control) signaling is realized；

Second step, base station are the feedback format that terminal configures PUCCH, i.e., using which kind of PUCCH format Feedback A/N, the configuration are realized by RRC signaling；

3rd step, if terminal configured based on RRC signaling carrier number, dual-mode, TDD then bases The time slot proportion and number of transport blocks of TDD, determines the bit number of A/N feedbacks；

4th step, it is determined that after number of bits of feedback, the feedback format transmission configured based on RRC；

5th step, is transmitted when terminal is configured for PUCCH format3, but in feedback window only Pcell is scheduled 1 sub-frame transmission, then terminal is automatically retracted back into PUCCH format 1a (format 1a) Or PUCCH format1b are transmitted；And base station side is then directed to PUCCH format3 and PUCCH simultaneously Format1a/1b is detected that RRC configurations obscure final end and base station understanding is mismatched to avoid.

And for carrier aggregation strengthens, the target of Current protocol design is to support the carrier aggregation skill of 32 carrier waves Art.As current feedback format could support up 5 carrier aggregations, then new upload control will necessarily be designed Feedback of the information form, to support that the A/N of 32 carrier aggregations feeds back.

For more carrier aggregations, base station can be the carrier wave that terminal configures more number, it is contemplated that The loading condition of different carrier waves can be dynamically which carrier wave of terminal scheduling for current carrier aggregation transfer.

If being based on existing protocol, no matter being how many carrier waves of terminal scheduling, the feedback of RRC configurations is all based on Number is transmitted, then can cause the waste of feedback resources.For example, base station is matched somebody with somebody for terminal by RRC signaling The A/N feedback formats for supporting 32 carrier aggregations are put, and when dispatching, has been only the less carrier wave of user scheduling Carrier aggregation transmission is carried out, the waste of resource can be caused if the feedback format based on configuration.

In order to reduce feedback overhead, separately feedback lattice can be carried out by the carrier number of base station and terminal based on dynamic dispatching Formula determines and feedback resources determine.But, as user equipment downlink detection Downlink Control Information (DCI) can Can there is missing inspection, it is possible to which the scheduling carrier wave number that the scheduling carrier wave number and base station for causing terminal understanding is adopted differs The problem of cause.Further, since the transmission data block number that base station is sent to terminal on some carrier wave is also Informed by DCI information, if after user equipment downlink detection DCI missing inspections, will be unable to know on the carrier wave to eventually The transmission data block number of end transmission, the tune that the scheduled transmission data block number and base station for causing terminal understanding is adopted Degree transmission data block number is inconsistent.
