Description
Technical field
The present invention relates to the communications field, in particular to a kind of processing method of persistent resource, terminal and base station.
Background technology
In a communications system, base station (BaseStation, referred to as BS) be the equipment showing Terminal for service, base station is communicated with terminal by uplink downlink, descending (forward direction) refers to that the direction of terminal is arrived in base station, and up (oppositely) refers to the direction of terminal to base station.Multiple terminal can send data by up link to base station simultaneously, also can receive data from base station by down link simultaneously.
In the formulation process of communication standard, how effectively to reduce communication system control overhead is subject to more and more company concern with the throughput increasing whole system.For periodically and data package size and modulating-coding speed (MCS) geostationary business, the method for a kind of persistent assignments (PersistentAllocation, referred to as PA) is usually adopted to carry out management resource.When periodic traffic starts, the resource that base station assigns is fixed is to terminal, and transmission comprises PA accordingly and distributes the control message of content to terminal, this resource allocation message only sends once when starting, terminal utilizes the fixed resource distributing to it receive or send data afterwards, this PA distribution is just stopped when situation occurs until resource release or resource changing or channel conditions change etc., as can be seen here, the method that PA distributes can greatly reduce the expense of the control message of Resourse Distribute.
At Institute of Electrical and Electric Engineers (InstituteforElectricalandElectronicEngineers, referred to as IEEE) in the formulation process of 802 series standards, relevant description has been done to persistent assignment of resources technology, the design original intention of this technology is saved having specific transmission cycle and the relatively-stationary terminal resource of long data packet distributes and describes expense to improve the performance of system, comprises message definition, hole-filling, resource go the contents such as distribution, Resourse Distribute.But the cycle sent due to persistent assignment of resources message (PAMAP) is long, thus terminal can correctly receive this message most important, terminal needs the reception condition confirming MAP message to base station feedback.When terminal receives new PA distribution, send positive feedback to base station and confirm (ACK) message (also can be called correct response message); When mistake appears in decoding terminals MAP message, send negative feedback (NACK) message (also can be called error feedback message) to base station.The distribution how adjusting persistent resource is determined according to the feedback of terminal in base station.
Resource when Fig. 1 is the terminal reception downlink or uplink persistent assignment of resources according to correlation technique uses schematic diagram, (a) wherein in Fig. 1 is the process of base station to the descending persistent resource of terminal distribution, as shown in (a) in Fig. 1, base station sends persistent assignment of resources message at (k-4) frame, for terminal MS 1, MS2, MS3 allocation of downlink persistent resource, because MS3 does not successfully receive this MAP message, then MS3 can not go the data that decoding base station sends on the descending persistent resource of (k-4) frame, cause the waste of downlink resource, (b) in Fig. 1 is the process of base station to the up persistent resource of terminal distribution, base station sends persistent assignment of resources message at (k-4) frame, for terminal MS 1, MS2, MS3 distributes up persistent resource, because MS1 does not successfully receive this MAP message, then MS1 can not send upstream data on the up persistent resource of (k-4) frame, cause the waste of ascending resource.
Fig. 2 is the schematic diagram of the Resource Block movement when terminal receives mapping message failure according to correlation technique, and Fig. 2 describes the processing procedure filling up resource cavity.As shown in Figure 2, BS sends MAP message at K frame (FrameK) and comes instruct MS 1 releasing resource and concrete resource block location and size, and BS indicates needs filling cavity, now BS and MS just carrys out transceiving data according to the resource location after hole-filling.Specifically, be exactly that MS2 and MS3 moves its resource block location to the cavity of causing after filling up MS1 releasing resource.As shown in Figure 2, MS2 makes mistakes at frameK decodes MAP messages, so MS2 stops data transmit-receive immediately, and send after two frames NACK to BS, BS by transmission new MAP message indicate PA recover (in the frameK+4 moment).Before PA recovers, the data of MS2 just lost.Make mistakes if MS2 resolves MAP message and do not stop transceiving data, conflicting after so MS3 moves its resource block location by with the resource block location of MS2, MS2 and MS3 can not normal transceiving data.At filling cavity mobile resources position process in the middle of, when not obtaining just starting to apply new PA, therefore, once MAP message decoding error will cause loss of data or make mistakes MS receives MAP message feedback acknowledgment.
