Description
Technical field
The present invention relates to the mobile wireless data transmission system, relate in particular to a kind of method and apparatus that transmits and receive data based on resource dispatching strategy.
Background technology
Development along with wireless mobile communications, the user has proposed more and more higher requirement to the speed and the service quality of radio communication, but because the shortage of radio spectrum resources has limited further developing of radio communication, on the other hand, the multipath of wireless channel and time-varying characteristics can bring very big infringement to the signal of wherein transmission, and these two in esse problems all become the obstruction of radio communication development.The multi-carrier OFDM of Chu Xianing (OFDM, Orthogonal Frequency Division Multiplexing) technology is also because can overcome the multipath characteristics of wireless channel and the focus that the characteristics higher than single carrier frequency spectrum efficiency become research well in recent years.These two kinds of technology mutually combine becomes key technology in the mobile communication system.
The OFDM technology is as the frequency multiplexing technique with transmission of high-rate data service ability, and on the one hand, for traditional single-carrier technology, the OFDM technology can utilize simple equalization algorithm that higher spectrum efficiency is provided; On the other hand; in the system that adopts OFDM, do not need the traditional frequency division multiplex (FDM, Frequency Division Multiplexing) of picture between adjacent carrier wave, to distribute the protection bandwidth of broad like that; just can avoid the phase mutual interference between the subcarrier, thereby save bandwidth.
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 and MIMO combination has also been finished standard and has been worked out 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.
Adopt 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 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 the figure 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, can be T by increasing less Cyclic Prefix therefore
Cp, to 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, above-mentioned advantage can be embodied in the practical application of system fully, adequate resources allocation schedule mechanism must be arranged.The actual environment for use of this and system is closely related, also with the user use professional closely related.
OFDMA system resource allocation scheduling mechanism is a mechanism that waits factor that the two-dimentional resource of OFDM symbol (time) subcarrier (frequency) is distributed, dispatched according to demand.
Resource allocation comprises fixing (sticky) and on-fixed (non-sticky) dual mode in the ofdm system.The Sticky mode is that the base station is distributed to a specific user or a particular group to a specific resources in the running time-frequency resource according to specific period.This method of salary distribution is primarily aimed at the business of some periodic regular lengths, for example E1, T1 and VoIP etc.The Non-sticky mode is that the specific resources of one period duration is distributed to a specific user or a specific customer group, and this resource just is released after the expiration.This method of salary distribution is primarily aimed at some aperiodic data service, for example HTFP, FTP etc.
The base station is informed the user to the message of resource allocation by sharing signaling channel (SSCH:Shared SignalingChannel).Resource allocation message comprises the user of appointment or the ID of customer group correspondence, the position and the size of Resources allocation, may also be included in modulation coding mode of these transmitted over resources data or the like.If the resource allocation message under the non-sticky mode, then this message comprises that also this specific resources takies lasting frame number.If the assignment messages under the sticky mode, then this message is as long as inform user or customer group when broadcasting for the first time, subsequent frame no longer needs to broadcast this message, unless increase sticky mode resource, reduce sticky mode resource, reclaim this resource or find packet loss.If the assignment messages under the non-sticky mode, then this message is as long as inform that user or customer group, subsequent frame no longer need to broadcast this message when broadcasting for the first time, and this resource is released after expiration.
After Sticky mode cycle of agreement when create connecting distributes to specific user or particular group to specific resources, need not take the SSCH resource again and send assignment messages, when the data of not having this user or customer group send, can send very short message and show that to the user this resource still keeps the sticky method of salary distribution.The Sticky method of salary distribution has reduced signaling when scheduling of resource, and simultaneously, for the reverse link resources request, the Sticky method of salary distribution has also reduced the time of Signalling exchange, has promptly reduced request and has postponed.
Fig. 2 illustrates the handling process according to the sticky mode transmitter side of prior art.
In step 201, the base station distributes the sticky resource to use to the user by sharing signaling channel.
In step 202, the base station judges whether this traffic assignments finishes.If then change done state over to.If, then entering the sticky cycle less than end on step 203, this traffic assignments judges.
If the current sticky cycle does not arrive, then on step 204, then wait for.
If current is the sticky cycle, then the base station judges whether the user has packets need to send on step 205.
If there is packet to send, then on step 206, carry out normal handling, use this sticky resource to send data, enter wait state then.
If there is not user data package to need to send, then on step 207, sends and mourn in silence sequence to sticky user.
Fig. 3 illustrates the handling process according to the sticky mode receiver side of prior art.
In step 301, the user is known the sticky resource that is assigned with by sharing signaling channel.
In step 302, whether the detection sticky cycle has arrived.If arrived, then on step 303, use this sticky resource to receive data.Otherwise on step 304, continue to wait for.
This shows that if there are not data to send on the resource that the sticky mode is distributed, this resource will be wasted.
