Description

Method, system and device for transmitting and receiving feedback information. The present application claims to be submitted to the Chinese Patent Office on February 2, 2012, the application number is 201210023581.1, and the invention is entitled "A method, system and device for transmitting and receiving feedback information" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, system, and apparatus for transmitting and receiving feedback information. Background technique

In the current Long Term Evolution (LTE) system, there can be only one carrier in a cell, and the maximum bandwidth is 20Mhz, as shown in Figure 1A.

For the LTE-Advanced (LTE-A) system, the peak rate of the LTE-A system is greatly improved compared with the LTE system. The LTE-A system requires downlink lGbps and uplink 500 Mbps. Obviously, the bandwidth of 20Mhz is no longer sufficient for this demand. In order to enable the LTE-A system to meet the requirements, a Carrier Aggregation (CA) technology is introduced, that is, a plurality of carriers that are consecutive or discontinuous are grouped together in the same cell, and simultaneously serve the user equipment when needed, to provide The required rate, therefore, the LTE-A system is a multi-carrier system. In order to ensure that the user equipment of the LTE-A system can work under each aggregated carrier, each carrier does not exceed 20Mhz at most. The CA technology of LTE-A is shown in Figure IB.

In the LTE-A system in Fig. 1B, four carriers are aggregated. The base station can perform data transmission with the user equipment on four carriers at the same time to improve system throughput.

For the LTE TDD system, the UE (User Equipment) may feed back Acknowledge/ Negative Acknowledge (ACK/NACK) information corresponding to multiple downlink subframes in one uplink subframe, that is, the UE is completed. After demodulating and decoding the data on the downlink subframe n_k, the base station/7 is fed back to the base station whether the data on the downlink subframe needs to be retransmitted signaling (ie, ACK/NACK). K, the value of the set K is related to the uplink and downlink configuration of the system and the specific subframe number. For details, see Table 1. Uplink and downlink subframe number

Multiple radio frames are sequentially arranged, that is, if the last subframe in the radio frame is A, the first subframe in the radio frame + 1 is A + Table 1 Only one radio frame is given as an example. The case corresponding to the frame, where n - k < 0 represents the downlink subframe in the previous radio frame.

In LTE Release 11 (Rel-11) or later systems, in order to avoid interference with other Time Division Duplex (TDD) systems, LTE cells located in different Bands may use different TDDs. The downlink subframe configuration is as shown in Figure 1C. Carrier 1 and carrier 2 are located in Band A, carrier 3 is located in Band B, and cell 1, cell 2, and cell 3 are cells on carrier 1, carrier 2, and carrier 3, respectively. The TDD uplink and downlink configurations of the cell 1 and the cell 2 are the same, both of which are configured 1. The TDD uplink and downlink subframe configuration of the cell 3 is different from that of the cell 1 and the cell 2, and is configured as 2. If the UE wants to use the three cells for carrier aggregation, a plurality of TDD uplink and downlink configurations may occur in all the aggregated cells of the UE.

The current standard stipulates that for the TDD inter-band CA, the Physical Uplink Control Channel (PUCCH) is transmitted only in the uplink primary carrier, that is, it needs to support the use of the uplink primary carrier feedback on all frequency bands. ACK/NACK corresponding to the Physical Downlink Shared Channel (PDSCH). In a more compact manner, the UE transmits ACK/NACK according to Hybrid Automatic Repeat reQuest timing ( HARQ timing) corresponding to a reference configuration, and the reference configuration is in the seven configurations of Table 1. One type, and may be the same as the uplink and downlink configuration on a certain band aggregated by the UE, or may be different from the uplink and downlink configuration on each band aggregated by the UE. The selection of the reference configuration may be related to an uplink and downlink configuration on multiple bands aggregated by the UE, or an uplink and downlink configuration on multiple activated bands. Therefore, when the base station reconfigures the band aggregated by the UE or activates/deactivates the reconfiguration, the reference configuration may change.

To improve the efficiency of the TDD system, a dynamic uplink-downlink subframe configuration scheme is proposed, that is, the uplink-downlink subframe ratio is adjusted according to real-time service requirements and channel conditions (that is, the TDD uplink and downlink configuration is changed). The upstream and downstream configurations are usually adjusted in a certain period. For example, the TDD uplink and downlink configurations are reconfigured according to service requirements in a period of 640 ms. Generally, PDSCH HARQ timing is bound to the uplink and downlink configuration. When the uplink and downlink configurations in the system are reconfigured, the PDSCH HARQ timing will change accordingly.

The reconfiguration is notified by higher layer signaling, such as Radio Resource Control (RRC) signaling or Media Access Control (MAC; Control Element, CE) signaling. The maximum delay requirement for RRC reconfiguration in the LTE system is 15 ms, and the maximum delay requirement for MAC CE reconfiguration is 8 ms. but Different UEs have different processing capabilities, and the actual processing delays required are different. For a UE with strong processing capability, reconfiguration can be completed before n+k (k<8 or k<15), and the base station cannot know the difference. UE corresponding to k, so subframe "subframe" + ⁸ "between + ^15, the presence of the base station and the UE may be configured to understand the discrepancies, i.e. every reconfiguration base station can not determine the period of Fuzzy When the UE starts to work according to the new configuration, it also causes the base station and the UE to directly understand the configuration inconsistency.

In summary, the understanding of the configuration between the base station and the UE is inconsistent in the current reconfiguration of the fuzzy time period, so that the base station cannot correctly receive the feedback information of the UE. Summary of the invention

Finally, the implementations from the network side and the user equipment side will be described separately, but this does not mean that the two must be implemented together. In fact, When the network side is implemented separately from the user equipment side, the problems existing on the network side and the user equipment side are also solved, but when the two are combined, a better technical effect is obtained.

Otherwise m = k + T , where τ is not less than the maximum reconfiguration delay specified by the system.

The τ in the above manner may be specified in the protocol; the user equipment may be notified after being determined by the network side; or may be determined by the network side and the user equipment after negotiation. If the reconfiguration is RRC reconfiguration, the maximum reconfiguration delay specified by the system is 15ms; if the reconfiguration is MAC reconfiguration, the maximum reconfiguration delay specified by the system is 8ms.
