Abstract
The invention discloses a feedback method of ACK/NACK under carrier aggregation, user equipment and a system thereof. The carrier aggregation is carried out in a long term evolution (LTE) system and a high speed downlink packet access (HSDPA) system. A time starting point of a radio frame of the LTE system and the time starting point of the radio frame of the HSDPA system are completely aligned. When the ACK/NACK is needed to be fed back aiming at a high speed-physical downlink shared channel (HS-PDSCH) at a present moment and the ACK/NACK which is fed back needs to be emitted through a carrier wave of the LTE system, a base station distributes resources of a first time slot and a second time slot for UE so that the UE on the LTE carrier wave emits the ACK/NACK through the first time slot and the second time slot or the second time slot. When the LTE system and the HSDPA system carry out the carrier aggregation and the feedback concentrates on the LTE system carrier wave, because a timing relationship of the ACK/NACK fed back by the LTE system and the timing relationship of the ACK/NACK fed back by the HSDPA system are different, HSDPA system performance is reduced. By using the method, the equipment and the system of the invention, the above problem can be solved.
Description
Technical field
The present invention relates to GSM, be meant feedback method, subscriber equipment and the system of confirmation under a kind of carrier aggregation (ACK/NACK) especially.
Background technology
According to 3G (Third Generation) Moblie partner program (3GPP; Third Generation Partnership Project) motion RP-110384 (load balancing between wireless access technology and carrier aggregation in the 51st plenary session of wireless access network; Inter-RAT load balancing_carrier aggregation); Long Term Evolution (LTE, Long Term Evolution) system and high-speed packet access system (HSPA, High Speed Packet Access) may carry out carrier aggregation in the future; That is to say; A Multi-Mode Base Station can be launched LTE signal and HSPA signal simultaneously to a multimode UE, and a Multi-Mode Base Station can receive LTE signal and HSPA signal from a multimode UE simultaneously, and transmits and receives and can carry out simultaneously.
The 7.3rd joint according to 3GPP TS 36.213V10.0.0; When base station scheduling the Physical Downlink Shared Channel (PDSCH of UE; Physical Downlink Shared Channel) and the base station do not dispatch the Physical Uplink Shared Channel (PUSCH of UE; Physical Uplink Shared Channel) time, UE can pass through Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and give base station feedback ACK/NACK (ACK or NACK).
The 7.3rd joint according to 3GPP TS 36.213V10.0.0; When base station scheduling UE PDSCH and base station scheduling during the PUSCH of UE; UE can pass through Physical Uplink Shared Channel (PUSCH; Physical Uplink Shared Channel) gives base station feedback ACK/NACK, also can give base station feedback ACK/NACK through PUCCH.
According to the 4.1st joint of 3GPP TS 36.211V10.0.0, the time span of a radio frames is 10ms (millisecond) among the LTE-Advanced, and dividing equally is 10 sub-frame, and the time span of each subframe is 1ms.
The 7.3rd joint according to 3GPP TS 36.213 V10.0.0; For frequency division duplex system (FDD; Frequency Division Duplexing), the 4ms emission ACK/NACK (ACK/NACK possibly on PUCCH send out, also possibly on PUSCH send out) of UE after receiving PDSCH.The timing relationship of PDSCH and ACK/NACK is as shown in Figure 1, and no matter ACK/NACK launches on PUCCH, still on PUSCH, launches, and the timing relationship of PDSCH and ACK/NACK is unaffected.
The 7.7th joint according to 3GPP TS 25.211V10.0.0; For broadband CDMA system (WCDMA; Wideband Code Division Multiple Access); UE just launches ACK/NACK after receiving high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH, High Speed-PDSCH) 5ms.The timing relationship of HS-PDSCH and ACK/NACK is as shown in Figure 2.
The 7.1st joint according to 3GPP TS 25.211V10.0.0; For WCDMA high speed descending grouping access system (HSDPA; High Speed Downlink Packet Access); First High-Speed Shared Control Channel (HS-SCCH, High Speed-Shared Control Channel) subframe (being HS-SCCH subframe 0) snaps to the beginning of a radio frames, and is as shown in Figure 2.
When a UE supports to receive and/or send LTE system carrier and HSPA system carrier simultaneously; UE can be respectively at feeding back ACK/NACK on LTE system carrier and HSPA system carrier, also can be as LTE-Advanced focuses on the emission of getting on of a carrier wave to ACK/NACK.
When base station scheduling HS-PDSCH and the UE of UE when focusing on ACK/NACK a carrier wave and get on to launch; If the radio frames of HSDPA with respect to the timing of the radio frames of LTE in advance 1280 chips (length of a chip is 1/3840000s) or in advance WCDMA half time slot or in advance during 1/3ms, UE uses conventional mode to launch ACK/NACK.
When base station scheduling HS-PDSCH and the UE of UE when focusing on ACK/NACK a carrier wave and get on to launch; If the start time and the terminal point of the radio frames of the radio frames of HSDPA and LTE are aimed at (the radio frames length of HSDPA, the radio frames length of LTE all are 10ms) fully, may make because of the difference of the timing relationship of their feeding back ACK/NACK should some difficulty of operation.Reason is; The ACK/NACK of LTE system can be than the early 1/3ms, perhaps late to 2/3ms that arrives of the ACK/NACK of HSDPA system; Therefore; The time of LTE system feedback ACK/NACK does not align with the zero-time of HSDPA system feedback ACK/NACK, when concentrating on the ACK/NACK feedback on the LTE system carrier, will cause the systematic function of HSDPA to reduce.
Can find out from top analysis; The LTE system and the HSDPA system carries out carrier aggregation and be tied to ACK/NACK (promptly at this time do not have ACK/NACK on the HSDPA system carrier) on the LTE system carrier and the situation of the ACK/NACK of LTE system than early 1/3ms of arrival of the ACK/NACK of HSDPA system or late arrival 2/3ms under; Need certain method and make UE feeding back ACK/NACK preferably, thereby solve timing relationship different of above-mentioned LTE system and HSDPA system feedback ACK/NACK and problem that the systematic function of the HSDPA that causes reduces.
Summary of the invention
In view of this; Main purpose of the present invention is to provide feedback method, subscriber equipment and the system of confirmation under a kind of carrier aggregation; Carry out carrier aggregation and ACK/NACK feedback when concentrating on the LTE system carrier to solve LTE system and HSDPA system, owing to the problem of the systematic function reduction of the LTE system and the different HSDPA that cause of the timing relationship of HSDPA system feedback ACK/NACK.
