The method of a kind of uplink control channel resource configuration of the embodiment of the invention, equipment and system, this method comprises: distribute the uplink control channel resource set, comprise the available channel resource numbering of a plurality of ACK/NACK feedbacks in this resource collection, judgement is on the up-link carrier that carries out the ACK/NACK feedback, the uplink control channel resource that whether has physical downlink control channel PDCCH on the descending carrier to be feedback, and according to result of determination the sign that can use resource is set in PDCCH, whether this can use the sign of resource be used for to indicate user terminal to use channel resource of described uplink control channel resource set to carry out the ACK/NACK feedback, and the operating position of channel resource element in should set; User terminal reads the configuration signal that the base station issues, know described uplink control channel resource set, detect the PDCCH of descending carrier to be feedback, determine whether to use channel resource in the described uplink control channel resource set according to the sign that can use resource, and the operating position of channel resource element in should set.
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 feed back the ACK/NACK information of PDSCH correspondence on a plurality of descending carriers and/or the ACK/NACK information of the PDCCH that a plurality of indication SPS resource discharges at the PUCCH of a up-link carrier, 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, the uplink control channel resource that has the CCE correspondence of PDCCH on the descending carrier to be feedback, namely reserve the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback at the up-link carrier that carries out the ACK/NACK 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 can use resource namely is set in PDCCH) both can be newly to arrange for DCI (downlink control information, Downlink Control Information) form that all PDCCH carry
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, namely 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 arrange for all PDCCH go up the DCI 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.
Embodiment as shown in Figure 6, the ACK/NACK information of the PDCCH that the ACK/NACK information of user terminal PDSCH correspondence on feeding back downlink carrier wave 1,2,3,4 on the up-link carrier 1 and/or indication SPS resource discharge.The base station by the RRC signaling semi-static give this user terminal fixed allocation N＞=1 uplink control channel resource, establish N=7 in the present embodiment, in the high-rise channel resource set that distributes of expression 7 channel resource elements are arranged.If go up the DCI form of carrying newly arranges for all PDCCH
The signaling of bit then during N=7, then need newly arrange the signaling of 3 bits on the DCI of all PDCCH form.
In up-link carrier 1, reserved the uplink control channel resource of the CCE correspondence of PDCCH on descending carrier 1 and the descending carrier 2, namely there is the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback.So, on descending carrier 1 and the descending carrier 2 ACK/NACK of PDSCH feedback just on these two descending carriers the uplink control channel resource of the CCE correspondence of PDCCH transmit.The base station needs respectively to use PDCCH to inform that user terminal does not use resource in the high-rise uplink control channel resource set that distributes as feedback channel at descending carrier 1 and descending carrier 2.For example, if newly arrange for all PDCCH go up the DCI form that carries
The signaling of bit during N=7, then can use " 000 " to inform that the ACK/NACK feedback of PDSCH on this descending carrier of user terminal do not use resource in the high-rise resource collection that distributes as the feedback channel of carrying feedback information.
But in up-link carrier 1, do not reserve the uplink control channel resource of descending carrier 3 and descending carrier 4, namely do not have the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback.So for the ACK/NACK feedback transmission of descending carrier 3 and descending carrier 4, need to use the resource number in the high-rise uplink control channel resource set of disposing.For descending carrier 3, the ACK/NACK information that the base station uses the PDCCH of descending carrier 3 to inform that user terminal feeds back the PDSCH of this carriers carry has been used which element in the set on earth.If go up the DCI form of carrying newly arranges for all PDCCH
The signaling of bit during N=7, then can use " 001 " to inform that the ACK/NACK feedback of PDSCH on this descending carrier of user terminal uses first channel resource in the high-rise resource collection that distributes as the feedback channel of carrying feedback information.
As shown in Figure 7, in the method that the embodiment of the invention provides, base station end processing procedure:

The signaling of bit, also can be 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 go up the DCI form of carrying newly arranges for all PDCCH
The signaling of bit, can with
Bit is set to complete zero, and the element in the high-rise resource collection that distributes is not used in expression.
Situation 2: on the up-link carrier that carries out the ACK/NACK feedback, do not have the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback, namely do not reserve the uplink control channel resource of the CCE correspondence of PDCCH on the descending carrier to be feedback.At this moment then the base station selects an element to feed back employed feedback channel as ACK/NACK in the uplink control channel resource set of distributing for this user, and utilizes the signaling of PDCCH to indicate to this resource element numbering of user terminal.The method of this PDCCH signaling both can be newly to arrange for all PDCCH go up the DCI form that carries
The signaling of bit, also can be 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 go up the DCI form of carrying newly arranges for all PDCCH
The signaling of bit, then the base station utilizes this
The channel resource element numbering (numbering is since 1) that the bit indication is selected for use, for example during N=7, then can use " 001 " to inform that the ACK/NACK feedback of PDSCH on this descending carrier of user terminal uses first channel resource in the high-rise resource collection that distributes as the feedback channel of carrying feedback information.
As shown in Figure 8, in the method that the embodiment of the invention provides, the user terminal processes process:
Step 801: read high-rise configuration signal, know the available uplink control channel resource set of ACK/NACK feedback that arranges in the base station;
Step 802: detect the PDCCH of descending carrier to be feedback, determine whether to use the element in the uplink control channel resource set; For example: if newly arrange for all PDCCH go up the DCI form that carries
The signaling of bit, when user terminal has detected complete zero bit status, then expression does not need to use element in the high-rise resource collection that distributes as feedback channel.And if detected other bit status, then expression needs to use element in the high-rise resource collection that distributes as feedback channel.User terminal is judged following two kinds of situations according to detected PDCCH:
Situation 1: do not use the element in the uplink control channel resource set.At this moment the indication of the CCE that then makes an appointment according to PDCCH on the descending carrier to be feedback is obtained ACK/NACK and is fed back employed channel resource numbering;
Situation 2: use the element in the uplink control channel resource set.At this moment then according to the indication of PDCCH, obtain ACK/NACK and feed back employed channel resource numbering (this numbering is in the scope of uplink control channel resource set);
Step 803: receive PDSCH, obtain the ACK/NACK feedback information after the decoding.
