Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of carrier resource distribution system and method.
Background technology
In recent years, broadband wireless communication technique has obtained swift and violent development, and people have promoted to be used for high-speed wideband development of wireless communication devices and application to the demand of wireless data multimedia service.OFDM (Orthogonal Frequency Division Multiplexing, be called for short OFDM) technology and multiple-input and multiple-output (Multiple-input Multiple-output, being called for short MIMO) technology is or be about to be used for various high-speed wideband wireless communication systems, but the technology that some are crucial, comprise pilot design, channel estimating, synchronized algorithm etc., still be left to be desired and solve.These designs and algorithm can help communication system overcome well wireless channel multipath and the time become two characteristics, these two characteristics also are to bring two problems of difficult maximum to wireless signal transmission.
The thought of frequency division multiplexing and parallel data transmission appears at nineteen sixties the earliest, and through the research and development of four more than ten years, the OFDM technology has become the high speed data transfer technology of extensive use.Wherein, a most important operation technique is fast fourier transform (Fast Fourier Transform is called for short FFT).It greatly reduces the difficulty of parallel data modulation, thereby makes the widely-used possibility that becomes of OFDM technology.In addition, Digital Signal Processing (Digital Signal Processing, be called for short DSP) and large scale integrated circuit (Very Large Scale Integration, being called for short VLSI) technology overcome and restricted the macrooperation amount that the OFDM technology exists and the problem of high-speed cache in the past, for the OFDM The Application of Technology has been paved road.
In concept, the basic thought of OFDM technology is that the data that needs transmit are distributed on the subcarriers of a large amount of transmission simultaneously, though each subcarrier adopts is modulation system than low rate, and owing to number of sub carrier wave is numerous, so integral body can be used high speed data transfer.Between these subcarriers by suitably selecting spectrum intervals to realize quadrature.With traditional frequency division multiplexing (Frequency Division Modulation is called for short FDM) difference, these subcarriers in the OFDM technology are to allow to overlap each other.The frequency spectrum of each subcarrier all is Sinc functions, and they do not disturb each other mutually in sample point.Can make full use of frequency spectrum resource like this, realize the very high availability of frequency spectrum, but also others be had higher requirement simultaneously.
At present, the OFDM technology has been widely used in the existing communication system, and this technology has been embodied among the WLAN standard 802.11a, and Related product has also obtained to use.The correlation technique of OFDM technology and the combination of MIMO technology is also finished the formulation of standard in IEEE802.16.In addition, in the mobile radio telecommunications connecting system, the wireless access network of third generation partner program (3GPP), the physical layer of IEEE 802.20 are also considering to use OFDM technology and MIMO technology, the mobile radio telecommunications connecting system that has higher frequency efficient with structure.
Adopted the data transmission system of OFDM technology to have the following advantages:
1) expansion has stronger fault-tolerance to multidiameter.As shown in Figure 1, comprise two parts on the OFDM symbol time domain: data division and Cyclic Prefix part, the Cyclic Prefix part is generated by the end circulation of data division, and the time that data division takies among Fig. 1 is T
Data, the time that Cyclic Prefix partly takies is T
CpThe fault-tolerance of OFDM technology shows: compare with the duration T s of an OFDM symbol, the duration of representative channel impulse response is very little, only takies very little part among the Ts, therefore can be by increasing less Cyclic Prefix, i.e. T
CpTo overcome the interference between signals that causes by multipath fully.
2) frequency selective fading had stronger fault-tolerance.The OFDM technology can be recovered the entrained digital signal of deep fade subcarrier by redundancy schemes such as employing chnnel codings.
3) adopted simple equalization algorithm.Because the OFDM technology adopts frequency domain to transmit signal, and acting on of channel shows as simple multiplication on the frequency domain, thereby makes the data transmission system that adopts the OFDM technology when carrying out signal equalization, only needs a simple single tap equalizers to realize.
4) for the FDM technology, the OFDM technology has higher spectrum efficiency.
Though adopt the data transmission system of OFDM technology to have above-mentioned advantage, but above-mentioned advantage can be embodied fully in the practical application of system, to make OFDM technology and MIMO technology organically be used in combination especially, must solve following key technology: the emission of sign synchronization, channel estimating and equilibrium, system broadcast information and reception etc.The actual environment for use of these key technologies and system is closely related, and also the network configuration with system requires closely related.
Divide for the resource allocation in every frame in the present mechanics of communication, main by sending shared signaling channel (Shared Signaling Channel, abbreviation SSCH) mode of notifying each user resources to distribute, the user can correctly handle it then by learning the position and the length at its data place in Traffic Channel after the information of SSCH is handled.
A kind of method is for using the method for skew+length (offset+length).As shown in Figure 2, each user has the deviant and the length value of a correspondence, this deviant and length value have been stipulated the scope of this user's data in Traffic Channel, so each user can correctly demodulate own needed data message in Traffic Channel by this deviant and length value.With Fig. 2 is example, and user 1 skew is 0, and length is 4, and 2 skews of user are 4, and length is 5.
Though this method can be utilized the resource of Traffic Channel fully,, make that the ample resources in each frame is not to be taken by Traffic Channel, but be used for transmitting the information of SSCH because offset information and the needed amount of information of length information are too big.
Another method is to carry out resource allocation by a kind of mode of tree structure, as shown in Figure 3.
This method mainly is the mode of distributing by node (Node), network layer can be according to what of each user's needs resource, distribute to its corresponding stock number, and this stock number is represented by a node, a user obtains taking up room of its resource by a node, for example suppose user 1, the resource that needs 4 logical sub carrier waves, then node 3 is distributed to user 1, user 1 has just taken 3 times all logical sub carrier waves of node like this, comprises the resource of logical sub carrier wave 15,16,17,18 in node 7 and the node 8.
Can expect easily, when user 1 needs the resource of 5 logical sub carrier waves, need distribute to user 1 to node 1 or node 2, what it obtained like this is exactly 8 logical sub carrier waves (15-22), yet user 1 has in fact only used the resource (15-19) of 5 logical sub carrier waves, and other 3 (20-22) other users can't use, and cause waste unnecessary on the resource.
Though owing to do not waste sub-carrier resources in the existing scheme one, owing to there is too much subcarrier to be used to transmit SSCH information, so Shi Ji resource utilization also is not high relatively, and the space of its lifting is not very big yet.The distribution method of existing scheme two has caused the waste of resource.
