Description

A kind of method, system and device of sending and receiving feedback information

Technical field

The present invention relates to wireless communication technology field, particularly a kind of method, system and device of sending and receiving feedback information.

Background technology

Current LTE (Long Term Evolution, Long Term Evolution) system, can only have a carrier wave in Yi Ge community, and maximum bandwidth is 20Mhz, as shown in Figure 1A.

For LTE-A (LTE-Advanced strengthens Long Term Evolution) system, the peak rate of LTE-A system is greatly improved than LTE system, and LTE-A system requirements reaches descending 1Gbps, up 500Mbps.Obviously, the bandwidth of 20Mhz cannot meet this demand.For LTE-A system can be met the requirements, introduce CA (Carrier Aggregation, carrier aggregation) technology, be in same community, continuous or discrete a plurality of carrier waves are concentrated in together, and are subscriber equipment service, so that required speed to be provided when needed simultaneously, therefore, LTE-A system is a multicarrier system.In order to guarantee that the subscriber equipment of LTE-A system can work under the carrier wave of each polymerization, each carrier wave maximum is no more than 20Mhz.The CA technology of LTE-A, as shown in Figure 1B.

In LTE-A system in Figure 1B, polymerization 4 carrier waves.Transfer of data can be carried out with subscriber equipment in base station simultaneously on 4 carrier waves, to improve throughput of system.

For LTE TDD system, UE (subscriber equipment) may feed back the corresponding ACK/NACK of a plurality of descending sub frames (correctly replying the instruction of instruction/wrong responses) information in a sub-frame of uplink, be that UE is after having completed the demodulation of the data on descending sub frame n-k, decoding, to on sub-frame of uplink n, to the data on this descending sub frame of base station feedback, whether need the signaling (being ACK/NACK) retransmitting, k ∈ K, the set value of K and the uplink-downlink configuration of system and concrete subframe are numbered relevant, specifically can be referring to table 1.

The regulation of the up direction feedback of table 1 downlink transfer

A plurality of radio frames are sequentially arranged, even in radio frames a, last subframe is k, in radio frames a+1, first subframe is k+1, table 1 take radio frames as example provided each sub-frame of uplink for the situation of K, 0 descending sub frame representing in last radio frames of n-k < wherein.

In the system of LTE Rel-11 or later version, for fear of to other TDD (Time division duplex, time division duplex) interference of system, is positioned at different B and (frequency band) LTE community and may uses different TDD up/down row sub-frame configuration, as shown in Figure 1 C.Wherein carrier wave 1 and carrier wave 2 are positioned at Band A, and carrier wave 3 is positioned at Band B, and community 1, community 2 and community 3 are respectively carrier wave 1, carrier wave 2 and carrier wave 3 Shang communities.The TDD uplink-downlink configuration of community 1 and community 2 is identical, is configuration 1, and the TDD up/down row sub-frame configuration of community 3 is different with community 2 from community 1, for configuring 2.If UE wishes to utilize Zhe Sange community to carry out carrier aggregation, so just there will be the situation that occurs multiple TDD uplink-downlink configuration in all aggregation cell of UE.

Standard regulation, across frequency band carriers polymerization (TDD inter-band CA), is used PUCCH only in up main carrier, to transmit for TDD at present, needs to support to use up main carrier to feed back ACK/NACK corresponding to PDSCH on all frequency bands.A kind of comparatively simple mode is, UE is according to a corresponding HARQ timing of reference configuration (Hybrid Automatic Repeat reQuest timing, mixed automatic retransfer request feedback timing relationship) transferring ACK/NACK, reference configuration is a kind of in 7 kinds of configurations of table 1, and may be identical with the uplink-downlink configuration on some band of UE institute polymerization, may be not identical with the uplink-downlink configuration on each band of UE institute polymerization yet.Reference configuration choose can with a plurality of band of UE institute polymerization on uplink-downlink configuration, or the uplink-downlink configuration on a plurality of band that activate is relevant.Therefore when reshuffle the band of UE polymerization base station or activation/deactivation is reshuffled, reference configuration may change.

For improving TDD system effectiveness, a kind of dynamic ascending-descending subframes allocation plan has been proposed at present, according to real-time business demand and channel conditions, adjust ascending-descending subframes ratio (changing TDD uplink-downlink configuration).For uplink-downlink configuration, normally with some cycles, adjust, as take 640ms and according to business demand, TDD uplink-downlink configuration is reshuffled as the cycle.Common PDSCH (Physical Downlink Shared Channel, physical down link sharing channel) HARQ timing and uplink-downlink configuration binding, after in system, uplink-downlink configuration is reshuffled, its PDSCH HARQ timing also can change accordingly.

Reshuffle by high-level signaling and notify, as RRC (Radio Resource Control, Radio Resource is controlled) signaling or MAC CE signaling.The maximum delay that LTE system is reshuffled RRC requires as 15ms, and the maximum delay that MAC CE (MAC control element, media access control layer control unit) reshuffles requires as 8ms.But the disposal ability of different UEs is different, its needed actual treatment time delay is different, the UE stronger for disposal ability can complete and reshuffle before at n+k (k < 8 or k < 15), the k that different UEs is corresponding cannot be known in base station, therefore at subframe n, arrive between subframe n+8 or n+15, having base station and UE may be inconsistent situation for the understanding of configuration, and in the Fuzzy Time section of at every turn reshuffling, base station cannot determine when UE starts to carry out work according to new configuration.Therefore also can cause base station with UE directly to the consistent inconsistent situation of understanding configuring.

In sum, consistent inconsistent to the understanding of configuration between base station and UE in the Fuzzy Time section of reshuffling at present, thus cause base station cannot correctly receive the feedback information of UE.
