Description
Technical field
The present invention relates to the communications field, and low especially, design a kind of wireless resource allocation methods.
Background technology
In wireless communication system, the base station is the equipment that service is provided to terminal, and the base station communicates by uplink and downlink link and terminal, and the direction of terminal is arrived in the descending base station that is meant, the up direction that is meant terminal to base station.A plurality of terminals can send data by up link to the base station simultaneously, also can receive data simultaneously from the base station by down link.Adopt the base station to realize in the wireless communication system of wireless resource scheduling control, the scheduling of system wireless resource distributes to be finished by the base station.When resource allocation information when for example, being provided the base station and transmitted by the base station and terminal are carried out uplink the resource allocation information that can use etc.
Develop rapidly along with the communication technology, the wireless communication system that has put it into commercial operation can't satisfy the demand of people to high transfer rate, high-speed mobile and the low time delay of wide-band mobile communication gradually, its the most direct performance is growing to high-speed data and smooth multimedia service demand, this has also proposed new requirement and challenge to future broadband wireless communication systems, especially the dispatching method of future broadband wireless communication systems is had higher requirement.
In current commercial wireless communication system, the base station is a dispatching cycle with a radio frames generally when the Radio Resource that scheduling is eated dishes without rice or wine, and the resource units that a radio frames is divided into several same size dispatched, for example, for a time slot or a code word, the base station can be dispatched all resources in the radio frames and be provided data or multimedia service to all terminals that the base station covers in dispatching cycle.
For example, with global system for mobile communications (Global System for Mobilecommunication, GSM) system is in the second generation radio communication of representative, the base station is divided into the Radio Resource of eating dishes without rice or wine time division multiple access (the TimeDivision Multiple Address of a 4.615ms on each frequency, TDMA) radio frames, each radio frames comprises 8 identical time slots, a time slot can transmit the speech channel of a full rate or two half rates, also can realize the data service of low speed.
And with wireless universal packet service (General Packet Radio Service, GPRS) in the 2.5 generation wireless communication systems for representative, even by introducing packet switching, be based on also that fixing time slot carries out, though data service rate is brought up to more than the 100kbps, but still can't be supported multimedia services such as video.
And with TD SDMA (Time-Division Sychronization CodeDivision Multiple Address, TD-SCDMA) in the third generation wireless communication system of representative, the base station is divided into the Radio Resource of eating dishes without rice or wine the radio frames that one-period is 10ms equally, each 10ms comprises 14 conventional time slots and 6 special time slots, wherein, conventional time slot is used to transmit concrete business and signaling, and on each conventional time slot, the user is distinguished by different code words in the base station.But in the future broadband wireless communication systems of B3G, for example, with Long Term Evolution (Long Term Envolution, LTE) system, Ultra-Mobile Broadband (UltraMobile Broadband, UMB), with IEEE 802.16m etc. in the mobile communication system of representative, owing to adopted Orthodoxy Frequency Division Multiplex (Orthogonal FrequencyDivision Multiplexing, OFDM) technology and OFDM (OrthogonalFrequency Division Multiple Address, OFDMA) technology, great change has also taken place in the constraints of wireless resource scheduling and requirement.
What wireless communication system was dispatched is the packet of all kinds business, and the basis of scheduling is corresponding frame structure.In the wireless communication system in future (for example, in the wireless communication system based on OFDM and OFDMA technology), generally the resource area that Radio Resource is divided into different brackets is dispatched, and for example, Radio Resource is divided framing, subframe and symbol tertiary structure dispatch.Particularly, can at first Radio Resource be divided into continuous frame of time, each frame is made up of a plurality of subframes, and subframe is made up of basic OFDM symbol.The subframe that comprises in frame and the number of OFDM symbol are by the basic parameter decision of ofdm system.
In addition, in order to improve efficiency of transmission, a plurality of subframes can be combined into the subframe zone and carry out combined dispatching.For example, as shown in Figure 1, the total Radio Resource of system is divided into identical frame of duration, and each frame is made up of N subframe, and each subframe then is made up of S basic OFDM symbol.In addition, the quaternary structure that also Radio Resource can be divided into superframe, frame, subframe and OFDM symbol is dispatched, thereby superframe is several frame levels to be connected together carry out unified scheduling and raise the efficiency.For example, be exactly F frame level to be connected together unify scheduling among Fig. 1.
Obviously, generally be Radio Resource to be divided into several less relatively zones (as subframe) dispatch, this is the basic characteristics of future broadband wireless communication systems, very important reason is the delay requirement that is to satisfy following professional real-time and various operations.And concerning the business of future broadband wireless communication systems, mainly can be divided into the professional and applied business of management type.The management type business mainly comprises administrative messags such as access, switching, scheduling, energy-conservation and feedback, and (Quality of Service QoS) requires to have nothing in common with each other for the dispatching cycle of these administrative messags, size, service quality; And applied business mainly comprises data, voice, video three classes, and data have comprised a lot of subclasses, and as a lot of concrete business such as Email, FTP, recreation, ecommerce, their dispatching cycle, size, qos requirement also have nothing in common with each other.
And when these business of scheduling, must determine adequate resources allocation unit or Resource Block (Resource Block, RB) size is dispatched miscellaneous service, the scheduling needs of various types of traffic should be farthest satisfied in the selection of this resource allocation unit or Resource Block, this be because the size of resource allocation unit or Resource Block to the utilance of the efficient of the complexity of wireless resource scheduling, scheduling and frequency spectrum important influence all.But from the type of service of future broadband wireless communication systems as can be known, be difficult to select such a kind of adequate resources allocation unit or resource block size.Only with regard to voice call (Voice Over Internet Protocol, VoIP) professional, VoIP encoder kind is also a lot, even only consider fixing a kind of VoIP encoder, for example, the AMR encoder just has eight kinds of speed, thereby produce eight kinds of bag sizes, it also is very difficult selecting adequate resources allocation unit or Resource Block.
And along with the progress of society, people are more and more to the type of service demand in the future broadband wireless communication systems, and the qos requirement difference of various types of traffic, thereby, scheduling requirement is also inequality, (Resource Allocation Unit, RAU) (for example, time slot and code word etc.) can not fully satisfy the characteristics of future broadband wireless communication systems to adopt single allocation of radio resources unit.In order to ensure the QoS of various types of traffic, guarantee the spectrum efficiency of future broadband wireless communication systems, be necessary to propose a kind of indicating means of new resource allocation unit, for the base station provides the ability of multiple radio resource scheduling granularity, thereby the transmission that ensures multiple business type in the future broadband wireless communication systems needs.Yet, do not propose as yet at present to reach this purpose technical scheme.
