As shown in Figure 5, present embodiment provides a kind of uplink control channel resource collocation method based on the consideration of compatible LTE system.
For the LTE-A carrier aggregation system, need be on a plurality of descending carriers of feedback on the PUCCH of a up-link carrier ACK/NACK information of the PDCCH that discharges of the ACK/NACK information of PDSCH correspondence and/or a plurality of indication SPS resource, so user terminal needs a plurality of uplink control channel resources carry out the ACK/NACK feedback.
In this uplink control channel resource set N＞=1 element is arranged, corresponding N the channel resource numbering that the ACK/NACK feedback is available.Channel resource element in this set can be shared by a plurality of user terminals, and the user terminal timesharing feedback of same channel resource has been used by the scheduling restriction in the base station, thereby avoids the channel resource collision problem.
The resource character of described uplink control channel resource set the inside is semi-continuous scheduling, and the base station disposes resource in this uplink control channel resource set by high-level signaling.
Wherein, if on the up-link carrier that carries out the ACK/NACK feedback, exist descending carrier to be feedback to end the uplink control channel resource of the CCE correspondence of PDCCH, promptly on the up-link carrier that carries out the ACK/NACK feedback, reserved the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback, then used this resource to feed back employed feedback channel as ACK/NACK.Do not need to utilize any one element in the high-rise uplink control channel resource set that distributes this moment; The base station utilizes PDCCH to inform that user terminal does not use the channel resource element in the high-rise set that distributes.
The method of this PDCCH signaling (method of the sign that can use resource promptly is set in PDCCH) both can be newly to be provided with for all PDCCH go up DCI (downlink control information, the Downlink Control Information) form that carries
The signaling of bit, also can with
Other signaling combined codings in the existing DCI form of the signaling of bit and Rel-8, even reuse this N+1 of denoting signaling state in the existing DCI form.
If but on the up-link carrier that carries out the ACK/NACK feedback, the uplink control channel resource that does not have the CCE correspondence of PDCCH on the descending carrier to be feedback, promptly do not reserve the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback, then need to utilize an element in the high-rise uplink control channel resource set that distributes to feed back employed feedback channel as ACK/NACK.The base station utilizes PDCCH to inform user terminal concrete resource element numbering of using in this set.The method of this PDCCH signaling both can be newly to be provided with for all PDCCH go up the DCI form that carries
