Embodiment

In the specific descriptions of following preferred embodiment, with reference to the appended accompanying drawing that forms a part of the present invention.Appended accompanying drawing shows by way of example can realize specific embodiment of the present invention.The embodiment of example is not intended to limit according to all embodiment of the present invention.Be appreciated that not departing under the prerequisite of scope of the present invention, can utilize other embodiment, also can carry out the modification of structural or logicality.Therefore, following specific descriptions are also nonrestrictive, and scope of the present invention is limited by appended claim.

Accompanying drawing 1 shows according to one embodiment of present invention, has described the carrier aggregation under FDD scene.Without loss of generality, UE in figure has been configured a principal component carrier wave, or title main plot (Primary Cell is called for short PCell), and one from component carrier, Huo Chengcong community (Secondly Cell is called for short SCell), it is pointed out that following execution mode of the present invention is obviously equally applicable to a main plot and a plurality of situation of carrier aggregation and carrier aggregation TDD scene of carrying out from community.

As shown in Figure 1, in this embodiment, part subframe from community is configured to carry out carrier aggregation to this UE, for example base station determines that according to the demand of business this UE is configured to a subframe every 8 milliseconds (i.e. 8 subframes) to be transmitted, in a certain frame as represented in accompanying drawing 1, descending sub frame 0, descending sub frame 8, comprises that the part descending sub frames such as descending sub frame 6 of next frame are configured to use to this UE after 8 not shown ms intervals.Therefore UE only exists from communityon above-mentioned descending sub frame, receive signal, and carry out corresponding PDCCH decode operation; On other descending sub frames of Er Gaicong community, UE neither receives signal, does not also carry out PDCCH decoding.Simultaneously, HARQ mechanism due to system, need feedback to receive the ACK/NACK information of signal, to determine whether need to retransmit, base station also needs the part sub-frame of uplink that configures corresponding Cong community to send feedback information for UE, in a certain frame as represented in accompanying drawing 1, sub-frame of uplink 4, comprise that the part sub-frame of uplink such as sub-frame of uplink 2 of next frame are configured to use to this UE after 8 not shown ms intervals, therefore UE transmitted signal on above-mentioned sub-frame of uplink, feeds back the ACK/NACK information that receives signal; On other sub-frame of uplink of Er Gaicong community, UE is transmitted signal not.

In the present embodiment, base station can be by above-mentioned Cong community part sub-frame of uplink, from the information of cell downlink subframe, all by configuration messages, send to UE, but do not need all configurations of Ba Cong community all to send to UE, such as the information such as sub-frame configuration of MBSFN just without sending to UE; This configuration messages can pass through RRC (Radio Resource Control, Radio Resource is controlled) message and send to corresponding UE.Base station can also only comprise subframe initial position and cycle sign in corresponding configuration information, and UE receives after corresponding information, according to this initial position and cycle, derives voluntarily follow-up subframe.For example, base station can be by descending sub frame initial position 0, sub-frame of uplink initial position 4 and cycle sign 8 send to UE, UE can derive descending sub frame 8 accordingly, the part descending sub frames such as the descending sub frame 6 of next frame are configured to use to this UE, and the part sub-frame of uplink such as the sub-frame of uplink 2 of next frame are configured to use to this UE; Can reduce the content of configuration messages like this.

As preferably, base station can also only send from cell downlink subframe initial position and cycle sign, the HARQ configuration that at this moment UE can be current according to system, derive should which sub-frame of uplink of Cong community on feedback receive the ACK/NACK information of signal.For example base station can send to UE by descending sub frame initial position 0 and cycle sign 8, and the feedback interval of HARQ in current system configuration is 4 subframes, UE can derive the 4th sub-frame of uplink after receiving descending sub frame 0, be the ACK/NACK information of first descending sub frames of sub-frame of uplink 4 feedback, and the like go out follow-up part sub-frame of uplink; Can further reduce the content of configuration messages like this.Similarly, base station can only send from the sub-frame of uplink initial position of community and cycle sign, UE can configure according to the current HARQ of system, derives and on which descending sub frame of Cong community, receive the ACK/NACK information that base station sends, and now UE is at uplink data sending.

In order to adapt to, dispatch more dynamically UE, the present invention can also support the HARQ mechanism dynamically updating, the feedback that is HARQ is not to carry out according to the HARQ configuration in current system, but in configuration messages, increase the information for the current HARQ configuration of renewal system, and UE is receiving descending sub frame initial position, cycle identifies and should after the information for the current HARQ configuration of renewal system, derive accordingly, draws and on which sub-frame of uplink of Cong community, feed back the ACK/NACK information that receives signal.For example base station can be by descending sub frame initial position 0, feedback interval=5 that cycle sign 8 and the HARQ upgrading configure send to UE, UE can derive the 5th sub-frame of uplink after receiving descending sub frame 0, be the ACK/NACK information of first descending sub frames of sub-frame of uplink 5 feedback, and the like go out follow-up part sub-frame of uplink.

Accompanying drawing 2 shows according to still another embodiment of the invention, has described and has only had part descending carrier to carry out the scene of carrier aggregation.The upstream components carrier wave that Ji Cong only has community part descending sub frame to configure to UE use ,Er Gaicong community does not configure to this UE.In the present embodiment, UE need to feed back the ACK/NACK information that receives signal on the sub-frame of uplink of main plot.The TDD carrier waves that the present embodiment is particularly useful for different configurations carry out the situation of the carrier aggregation of the mixed configuration that polymerization or WeiFDD,Cong community, main plot are TDD.Because only have part descending sub frame to configure to UE, carry out carrier aggregation, and the up upstream components carrier wave that still uses original main plot, so for UE, still can be operated in original pattern, therefore has better backwards compatibility.

As shown in Figure 2, in this embodiment, part descending sub frame from community is configured to carry out carrier aggregation to this UE, for example base station determines that according to the demand of business this UE is configured to a subframe every 8 milliseconds (i.e. 8 subframes) to be transmitted, in a certain frame as represented in accompanying drawing 2, descending sub frame 0, descending sub frame 8, comprises that the part descending sub frames such as descending sub frame 6 of next frame are configured to use to this UE after 8 not shown ms intervals.Therefore UE only receives signal on above-mentioned descending sub frame, and carries out corresponding PDCCH decode operation; On other descending sub frames of Er Gaicong community, UE neither receives signal, does not also carry out PDCCH decoding.Simultaneously, HARQ mechanism due to system, need feedback to receive the ACK/NACK information of signal, to determine whether need to retransmit, therefore UE also need to send feedback information at the part sub-frame of uplink of main plot, in a certain frame as represented in accompanying drawing 2, and the sub-frame of uplink 4 in main plot, comprise transmitted signal on the part sub-frame of uplink such as sub-frame of uplink 2 of next frame after 8 not shown ms intervals, feedback receives the ACK/NACK information of signal.

In the present embodiment, base station can be by above-mentioned main plot part sub-frame of uplink, from the information of community part descending sub frame, all by configuration messages, send to UE, but do not need all configurations of Ba Cong community all to send to UE, such as the information such as sub-frame configuration of MBSFN just without sending to UE; This configuration messages can send to corresponding UE by RRC message.Base station can also only comprise subframe initial position and cycle sign in corresponding configuration information, and UE receives after corresponding information, according to this initial position and cycle, derives voluntarily follow-up subframe.For example, base station can be by from cell downlink subframe initial position 0, main plot sub-frame of uplink initial position 4 and cycle sign 8 send to UE, UE can derive accordingly from cell downlink subframe 8, from the part descending sub frames such as descending sub frame 6 of community next frame, be configured to use to this UE, the part sub-frame of uplink such as the sub-frame of uplink 2 of main plot next frame can receive for feedback the ACK/NACK information of signal; Can reduce the content of configuration messages like this.

As preferably, base station can also only send from cell downlink subframe initial position and cycle sign, and the HARQ configuration that at this moment UE can be current according to system, derives the ACK/NACK information that feed back reception signal on which sub-frame of uplink of main plot.For example base station can send to UE by descending sub frame initial position 0 and cycle sign 8, and the feedback interval of HARQ in current system configuration is 4 subframes, UE can derive the 4th sub-frame of uplink after receiving descending sub frame 0, in the ACK/NACK information of first descending sub frames of sub-frame of uplink 4 feedback of main plot, and the like go out follow-up part sub-frame of uplink; Can further reduce the content of configuration messages like this.

In order to adapt to, dispatch more dynamically UE, the present invention can also support the HARQ mechanism dynamically updating, be that HARQ feedback is not to carry out according to the HARQ configuration in current system, but in configuration messages, increase the information for the current HARQ configuration of renewal system, and UE is receiving descending sub frame initial position, cycle identifies and should after the information for the current HARQ configuration of renewal system, derive accordingly, draws and on which sub-frame of uplink of main plot, feed back the ACK/NACK information that receives signal.For example base station can be by descending sub frame initial position 0, feedback interval=5 that cycle sign 8 and the HARQ upgrading configure send to UE, UE can derive the 5th sub-frame of uplink after receiving descending sub frame 0, be the ACK/NACK information of first descending sub frames of main plot sub-frame of uplink 5 feedback, and the like go out follow-up part sub-frame of uplink.

Accompanying drawing 3 shows according to still another embodiment of the invention, has described the situation in one-component carrier wave with dissimilar subframe.Base station can be used the UE with different abilities (Capability) to these dissimilar sub-frame allocation, with this, increases the effective rate of utilization of bandwidth.For example, in one-component carrier wave, part subframe is backward compatibility LTE system, in this part subframe, all has PDCCH signal, and this part subframe can configure to LTE-A UE and use; Another part subframe is non-backward compatible LTE system, such as may be not containing the full gap frame of PDCCH signal (can for eliminating the interference between neighbor cell), or containing PDCCH signal only containing the subframe of PDSCH (Physical Downlink Shared Channel) signal (can for improving message transmission rate), this part subframe can configure to the UE of highest version more and use.By the method for the present embodiment, can use one-component allocation of carriers to dissimilar UE, thereby save frequency spectrum resource, improved spectrum efficiency.

As shown in Figure 3, in this component carrier, subframe 3 and subframe 8 are non-backward compatible LTE systems, and this part subframe can configure to the more UE use of highest version, and other subframe is backward compatibility LTE system, can configure to LTE-A UE and use.
