Description
Technical field
The present invention relates to the mobile communication technology field, particularly resource regulating method, device and communication system.
Background technology
VoIP (Voice over IP, IP phone) technology is LTE (Long Term Evolved, Long Term Evolution) a kind of very important business that system need to be supported, voip user's number that its maximum can be supported is one of important indicator of LTE systematic function.The characteristics of VoIP business are: in talking state, every 20ms produces a VoIP packet, and service load is 40 byte left and right; In silent status, every 160ms produces a SID (Silent Indicator, the indication of mourning in silence) packet, and service load is 15 byte left and right.VoIP business model schematic diagram under the AMR that Fig. 1 is prior art (Adaptive Multiple Rate, adaptive multi-rate) encoding scheme.
Due to the packet size and the regularity that reaches the time interval of VoIP business, in the LTE system, to the VoIP business, adopt SPS (Semi-Persistent Scheduling, semi-continuous scheduling) mode to save the expense of control signal.In this dispatching algorithm, once the voip user enters Talk spurt (audio session peak) state, this user will obtain fixing resource and distribute in certain time interval, it comprises fixing RB (resource block, Resource Block) quantity, RB position and MCS (Modulation andCoding Scheme, modulation coding mode).And, when pre-configured resource and MCS can not meet actual needs, use the dynamic dispatching control signal to change the transfer resource of VoIP business temporarily or forever.Wherein, for the LTE system, UP (Uplink, up) dynamic dispatching control signal is UL Grant (uplink authorization).Refer to Fig. 2, the concrete schematic diagram of the up semi-continuous scheduling SPS algorithm that Fig. 2 is prior art, as shown in Figure 2, ACK means correctly to reply (Acknowledge), for base station, to UE (UserEquipment, subscriber equipment) feedback, receive correctly, NAK means wrong responses (NegativeAcknowledge), for meaning that base station receives wrong packet, indication UE resends.
In addition, for up, what prior art adopted is synchronous HARQ (Hybrid AdaptiveRepeat Quest, mixed automatic retransfer), that is to say that the re-transmission of HARQ must be carried out in the fixing moment, at LTE FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)), in system, HARQ RTT (Round Trip Time, round-trip delay) is 8ms, i.e. 8 TTI (Transmission Time Interval, Transmission Time Interval).
In the situation that uplink in the LTE system, eNB (evolved Node B, the base station of evolution) need to be every fixing interval, and for example 20ms, be UE distribution SPS persistent resources; The interval that eNB also need to be fixing every another simultaneously, be for example 8ms, for distributing SPS, UE retransmits resource, for example, when distributing the SPS persistent resources and distribute SPS re-transmission resource to occur in synchronization (40ms), just produced conflict, eNB can't not only distribute SPS re-transmission resource but also distributes the SPS persistent resources at synchronization.
The solution of prior art is, when the SPS persistent resources is distributed and SPS when retransmitting the resource distribution and clashing, the moment occurred in this conflict distributes SPS to retransmit resource, and the several TTI subsequently distribute the SPS persistent resources, or the moment occurred in this conflict is only distributed the SPS persistent resources.
The inventor finds in realizing process of the present invention, and prior art at least has the following disadvantages: the method for prior art has increased propagation delay time, affects the user and experiences, and increased packet loss, reduced systematic function.

For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
The inventor finds in realizing process of the present invention, in the prior art, on the one hand, character according to the SPS scheduling, once the voip user enters Talk spurt state, eNB can be spaced apart UE according to regular time and distribute the first biography TB (Transmission Block, transmission block) of persistent resources with the transmission activated state; On the other hand, due to up employing be synchronous HARQ, once this also means not first the biographys TB of the correct UE of reception of eNB, eNB will distribute and retransmit resource with transmission re-transmission TB in the moment of next RTT for UE.If both of these case occurs in synchronization, can't dispatch two TB in LTE simultaneously, the TB therefore bumped must abandon or delay dispatching.
Based on above problem, the embodiment of the present invention provides a kind of resource regulating method, solve the distribution of re-transmission resource and SPS persistent resources and distribute afoul problem in the system that adopts the multicarrier framework, the method that the embodiment of the present invention provides for example can be applied in the system such as LTE-A (LTE-Advanced, enhancement mode Long Term Evolution).Consulting Fig. 3, is the structural representation of the HARQ under the multicarrier of the embodiment of the present invention.In embodiments of the present invention, the corresponding HARQ entity of each carrier wave, and also the HARQ entity of each carrier wave is separate.In embodiments of the present invention, in order to meet the more demand of peak value speed and cell throughout of enhanced services, the LTE-A system proposes to adopt carrier aggregation technology, supports wider bandwidth, thereby reaches higher peak rate.Because the LTE-A system of the embodiment of the present invention is supported multi-carrier scheduling, that is to say at same TTI and can dispatch on a plurality of carrier waves a plurality of TB that transmit, so the embodiment of the present invention provides a kind of solution to retransmit the resource distribution and the SPS persistent resources is distributed afoul method.
In the technical scheme provided in the embodiment of the present invention, owing to adopting the multi-carrier scheduling mode, thereby need for example, to notify UE by control signal (: PDCCH, RRC signaling) indication.The embodiment of the present invention has proposed a kind of new control signal and has notified UE, so that UE indicates and is transmitted on a plurality of carrier waves according to scheduling of resource, for example comprise: eNB adds specific sign in sending to the control signal of UE, with indication, the scheduling of resource clashed is sent to the another one carrier wave.ENB also sends this control signal on the another one carrier wave simultaneously, UE monitors the control signal of each carrier wave, after receiving this control signal, know by the sign comprised in this control signal the TTI that eNB is clashing, adopting the another one carrier wave is that UE has distributed resource, therefore, UE sends corresponding data according to distributed respective resources on this carrier wave.
