Description
Technical field
The present invention relates to the communications field, and especially, relate to 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 refers to, the up direction that refers to terminal to base station.A plurality of terminals can send data by up link to the base station simultaneously, also can be by down link simultaneously from the base station receive data.Adopt the base station to realize that the dispatching distribution of system wireless resource is finished by the base station in the wireless communication system of wireless resource scheduling control.Resource allocation information that can use when the resource allocation information when for example, being provided the base station and transmitted by the base station and terminal are carried out uplink etc.
Develop rapidly along with the communication technology, the wireless communication system that has put it into commercial operation can't satisfy people gradually to the demand of high transfer rate, high-speed mobile and the low time delay of wide-band mobile communication, it the most directly shows and is growing to high-speed data and smooth multimedia service demand, this has also proposed Secretary 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 when the Radio Resource that scheduling is eated dishes without rice or wine generally take a radio frames as a dispatching cycle, and the resource units that a radio frames is divided into several formed objects dispatched, for example, for a time slot or a code word, all resources in the radio frames can be dispatched and all terminals of covering to the base station provide data or multimedia service in the base station within 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, also being based on fixedly, time slot carries out, although data service rate is brought up to more than the 100kbps, but still can't be supported the 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 for transmitting 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 having adopted Orthodoxy Frequency Division Multiplex (Orthogonal FrequencyDivision Multiplexing, OFDM) technology and OFDM (OrthogonalFrequency Division Multiple Address, OFDMA) technology, great change has also occured 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, take OFDM and OFDMA technology in the wireless communication system on basis), the resource area that generally 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 the frame of Time Continuous, each frame is comprised of a plurality of subframes, and subframe is comprised of basic OFDM symbol.The subframe that comprises in frame and the number of OFDM symbol are determined by the basic parameter 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 comprised of N subframe, and each subframe then is comprised 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 carry out United Dispatching among Fig. 1.
Obviously, generally be that the zone (such as subframe) that Radio Resource is divided into several less is dispatched, this is the basic characteristics of future broadband wireless communication systems, and 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 management type business and applied business.The management type business mainly comprises the administrative messags such as access, switching, scheduling, energy-conservation and feedback, and the dispatching cycle of these administrative messags, size, service quality (Quality of Service, QoS) require different; And applied business mainly comprises data, voice, video three classes, and data have comprised a lot of subclasses, and such as a lot of concrete business such as Email, FTP, game, ecommerce, their dispatching cycle, size, qos requirement are also different.
And when these business of scheduling, must determine suitable resource 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, and this is because resource allocation unit or resource block size have important impact to the complexity of wireless resource scheduling, the efficient of scheduling and the utilance of frequency spectrum.But from the type of service of future broadband wireless communication systems as can be known, be difficult to select such a kind of suitable resource 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 suitable resource 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 of various types of traffic is different, thereby, the demand of scheduling is not identical yet, adopt single allocation of radio resources unit (Resource Allocation Unit, RAU) (for example, time slot and code word etc.) can not fully satisfy the characteristics of future broadband wireless communication systems.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, provide the ability of multiple radio resource scheduling granularity for the base station, thereby the transmission that ensures multiple business type in the future broadband wireless communication systems needs.Yet, not yet propose at present to reach this purpose technical scheme.
