Description

Resource allocation and control signal transmission method
Technical field
The present invention relates to wireless communication system, more specifically, relate to a kind of resource allocation and control signal transmission method.
Background technology
3GPP is the standardization body that formulates Wideband Code Division Multiple Access (WCDMA) (WCDMA) technical specification, has issued the multiple version technical specification relevant with Radio Access Network and core network.Above-mentioned Wideband Code Division Multiple Access (WCDMA) (WCDMA) system is based on orthogonal intersection and allows a plurality of users while transmission system and user profile in the 5MHz bandwidth, and the data transmission capabilities of its initial designs is that maximum data rate is 2Mbps under the transmission environment that the user does not move; Because above-mentioned maximum data transfer rate still can not satisfy the diversified professional transmission demand that occurs day by day, 3GPP standardization body is subsequently respectively to (BS) inserts (HSDPA) based on high speed downlink packet and to the up link of (BS) strengthens the transmittability of the uplink downlink of Wideband Code Division Multiple Access (WCDMA) (WCDMA) system based on high speed uplink packet access technology such as (HSUPA) to the base station from subscriber equipment (UE), the peak-peak speed that can reach up link and down link bearer service by this in theory is respectively about 5.76Mbps and 14Mbps to the down link of subscriber equipment (UE) from the base station; Because the transmittability that strengthens Wideband Code Division Multiple Access (WCDMA) (WCDMA) system still can not satisfy the business demand of high-transmission bandwidth, come the above-mentioned Wideband Code Division Multiple Access (WCDMA) of evolution (WCDMA) system so be necessary to introduce the new Radio Transmission Technology and the network architecture, Here it is, and 3GPP is using OFDM (OFDM) technology implementation to Wideband Code Division Multiple Access (WCDMA) (WCDMA) system's Long Term Evolution (LTE) technical specification.
In order to describe the technology of the present invention better, be necessary to be briefly described the basic principle of OFDM (OFDM) technology; OFDM is a kind of special multi-carrier modulation (MCM) tranmission techniques, and it is not to adopt traditional band pass filter to separate different carrier spectrums, but quadrature carrier modulation back transmitting system and the user profile of utilizing a plurality of frequency spectrums to overlap; The quadrature carrier place that above-mentioned frequency spectrum overlaps is called the OFDM subchannel; In traditional multi-carrier modulation (MCM) communication system, the whole system frequency band is divided into a plurality of subchannels that do not overlap mutually, and each subchannel is respectively by independently source symbol modulation, i.e. S subchannel frequency division multiplexing; Owing to need to give between the multiplexing carrier frequency of traditional multicarrier (MCM) and stay certain protection band separation; could recover the information sent by filter at receiving terminal; though the phase mutual interference that this has been avoided between the different subchannels is to have caused the relatively low availability of frequency spectrum with the protection frequency band that increases different carrier frequencies.
The particularity of above-mentioned OFDM is that it allows each intercarrier frequency to overlap mutually and quadrature, can realize that by utilizing above-mentioned orthogonal sub-channels technology reaches at the center frequency point place of each carrier wave and do not have other spectrum of carrier component, can save 50 percent channel width based on the discrete Fourier (DFT) of carrier frequency quadrature or fast Flourier (FFT) conversion.As the above, the OFDM technology no longer is to realize by a lot of band pass filters, but directly signal is implemented discrete Fourier (DFT) conversion, and this is the distinguishing feature that OFDM is different from other system.The high data rate of OFDM is relevant with the quantity of subcarrier, increases the transfer rate that number of sub carrier wave just can improve data, it should be noted that the restriction that is subjected to such as many physical factors such as oscillator phase, and OFDM can not have unlimited many number of subcarriers.In addition, the modulator approach of each frequency band of OFDM can be different, and it is suitable for the communication system of high flexibility and high spectrum utilization.
Two kinds of basic transmission modes have been defined, promptly local formula (Localized) transmission mode and distributed (Distributed) transmission mode in Long Term Evolution (LTE) the system wireless transmission plan of above-mentioned 3GPP based on OFDM (OFDM) technology.Local formula transmission mode of the present invention is meant that the base station gives the continuous subcarrier transmitting data of user equipment allocation at local frequency sub-band according to wireless transmission channel quality between base station and subscriber equipment, can utilize adaptive coding and modulating and frequency scheduling to obtain bigger transmission gain by this; Distributed transmission pattern of the present invention is meant the discontinuous subcarrier transmitting data that the base station is distributed in part or whole frequency for subscriber equipment (UE) according to wireless transmission channel quality between base station and subscriber equipment, is implemented in the acquisition frequency diversity gain under the situation of fast change of channel by this.
Physical source distributing is one of key technology of discussing in Long Term Evolution (LTE) the system wireless transmission plan of above-mentioned 3GPP based on OFDM (OFDM) technology, in brief exactly will through chnnel coding, interweave and modulate after information bit frequency symbol physical resource when how to be mapped to OFDM, each Physical Resource Block (PRB) be by N continuously M in the OFDM symbol continuously subcarrier constitute; Above-mentioned granularity of distributing physical resource need both satisfy the minimal service load request and consider many-sided demands such as transmission channel frequency characteristic again, based on above-mentioned consideration, above-mentioned 3GPP orders temporarily based on the big or small SPRB of basic Physical Resource Block in Long Term Evolution (LTE) the system wireless transmission plan of OFDM (OFDM) technology and is M * N, wherein M is the quantity of subcarrier, it can value be 25, N can value be the quantity of OFDM symbol in each subframe, based on foregoing description, table 1 has provided above-mentioned 3 GPP based on the 1.25MHz that defines in Long Term Evolution (LTE) the system wireless transmission plan of OFDM (OFDM) technology, 2.5MHz, 5.0MHz, 10.0MHz, 15.0MHz, and the Physical Resource Block bandwidth and the Physical Resource Block number of multiple systems transmission bandwidth (B) such as 20.0MHz.
Pairing Physical Resource Block bandwidth of different bandwidth and Physical Resource Block number in the table 1:LTE system wireless transmission plan
Bandwidth (MHz) 1.25 2.5 5.0 10.0 15.0 20.0

Need to prove that continuous number of subcarriers M value can change based on the result of study of the interference coordination (Interference Coordination) of OFDM (OFDM) transmission, for example M also can value 10,12,15 or other value.
For the present invention is described, be necessary to be described in further the notion of the virtual resource blocks that defines among the technical report TR25.814 of 3GPP, it has following two essential characteristics, be size and type, wherein size is to be tolerance according to running time-frequency resource, and type is meant local formula (Localized) or distributed (Distributed) pattern; The basic principle that is mapped to Physical Resource Block as for virtual resource blocks is that local formula virtual resource blocks is mapped on the Physical Resource Block with the local mode that is defined within the part physical resource, and distributed virtual resource block is mapped on the Physical Resource Block with the dispersing mode that is scattered within the part or all of physical resource, yet the detailed principle that virtual resource blocks is mapped to Physical Resource Block remains to be defined further.In addition, local formula transmission and distributed transmission are carried out frequency division multiplexing (FDM) in each subframe.
