Abstract
The method includes following steps: the wireless network controller allocates and manages the wireless channel resources; a mixed allocation mode combining the fixed-allocation with dynamic allocation is used to provide channels for base station and mobile station. The invention in use for channel allocation in TDD mobile communication system adopts central control and dispatch for wireless resources to improve the utilization rate of resources and the relevant transmission efficiency, and meanwhile to reduce the inter-cell interference and intra-cell interference.
Description
Technical field
The present invention relates to the distribution and the transmission technology of the radio channel resource in the mobile communication system, particularly the method for sub-district channel distribution in time division duplex (being called for short TDD) cell mobile communication systems.
Background technology
Cell mobile communication systems need be given each base station and travelling carriage with radio channel allocation, makes it can finish the professional transmission of uplink and downlink.Can distribute the uplink and downlink channel neatly according to the demand of business based on time division duplex (TDD) mobile communication system, realize effective transmission of symmetry and non-symmetrical service.
The target of channel allocation is to utilize radio channel resource to greatest extent, high speed transmission data signal under as far as possible little disturbed condition.In order to control the mobile communication system resource, adopt the pooling of resources management can effectively utilize Radio Resource and Internet resources.Consider the interference of minizone, the shared resource in each sub-district should be distinguished to some extent, and can it be separated effectively by certain identification means.Particularly need frequency in OFDM (being called for short OFDM) system, time slot and sign indicating number resource are carried out reasonable configuration, so that the resource utilization of obtaining greatlyyer.
The distribution method of channel generally has fixed channel assignment, and dynamic channel allocation and mixed channel distribute.
Fixed channel assignment (being called for short FCA) is according to each sub-district propagation characteristic and distribution of traffic feature, and channel resource is distributed to each base station regularly.But the problem that it brings is the variation that is unfavorable for system business and environment.
Dynamic channel allocation schemes (being called for short DCA) is that all channels all are placed in the resource pool.When a certain community user needed a Channel Transmission signal, radio resource controller can be carried out or refuse and distribute a channel to this community user according to the resource operating position.Although DCA can provide the quite high level of resources utilization and professional flexibly suitability,, make DCA in real system, be difficult to use because its algorithm computation complexity when high capacity is too high.
In order to overcome the defective of FCA and DCA, mixed channel distributes (being called for short HCA) with channel part standing part and dynamic two parts.It combines the characteristics of FCA and DCA, can realize the dynamic assignment of certain channel resource under limited computation complexity.
In order to further specify the mixed channel distribution method, Fig. 1 has described the mobile communication system resource allocation structure.By the sign indicating number territory, the different divisions of frequency domain and time domain can realize wireless system resources is distributed.Channel code is used to distinguish different sub-districts, and it can be determined before coming into operation in each sub-district.In message transmitting procedure, frequency domain resource and time-domain resource-frequency band and time slot can flexible allocation be given each community user.10 expression time-domain resource in Fig. 1, it is a domain space when dividing frame by frame, a frame time is made up of a plurality of time slots.20 expression frequency domains can be divided into the one section frequency band a plurality of sub-bands.30 indication code territories, specific code sequence that can be different to each cell configuration.As 40 sub-district #1 configuration C1 sign indicating number, 42 sub-district #2 configuration C2 sign indicating number, 48 sub-district # maximums (max) configuration Cmax sign indicating number etc.
In the processing method of existing resources management, often only consider the single subdistrict scheduling of resource, seldom consider the resource requirement that many sub-districts are different, perhaps with the separately design of uplink and downlink resource.The flexibility that TDD system multi-cell channel is distributed and reduce problem such as phase mutual interference and lack and consider as a whole.The adjustable characteristic of the system resource of TDD does not embody fully.In existing channel assignment scheme, all there are the problems referred to above.As when using the FCA algorithm, because each cell business volume difference can cause some cell channel resources not enough, and other cell channel resources is in idle condition.When using the DCA method, amount of calculation is bigger than normal, the network management complexity.Especially under the big situation of each cell business volume, realize difficulty more.Though the HCA method can merge the problem that solves each side, this method generally satisfies this cell business volume by using channel to neighbor cell; Or mark very the mini-bus part and take according to its traffic carrying capacity application as each sub-district, public domain.Problems such as this can cause the traffic carrying capacity adjusting range little, and resource control is also dumb.
Summary of the invention
The purpose of this invention is to provide a kind ofly,, provide the method for channel allocation that frequency bandwidth and time slot combine according to central controlled mixed channel distribution principle based on the time-frequency wireless channel resource allocation.It is assigned channels flexibly, and can reduce the interference of minizone.Improved the effective rate of utilization of the rate of information throughput and channel resource simultaneously.
For achieving the above object, a kind of based on the time-frequency wireless channel resource allocation, comprise step:
Radio network controller is concentrated and is distributed and the management radio channel resource;
The mixed ways of distribution that adopts fixed allocation and dynamic assignment to combine offers the base station with channel and travelling carriage communicates.
The present invention is applicable to TDD mobile communication system channel allocation, and it is the configurating channel resource neatly.The present invention has adopted centralized control and scheduling to Radio Resource, and network resource management is quick flexibly.Simultaneously, the utilance of resource is higher, and corresponding efficiency of transmission also is improved.The present invention makes the interference of minizone and the interference in the sub-district smaller by reasonable configuration time-frequency piece resource.Simultaneously, the present invention can realize in system easily.

Embodiment
The present invention has adopted the method for radio network controller (RNC) centralized control radio channel resource.It can utilize Radio Resource efficiently.Reduce the waste and the interference of channel.Fig. 2 has described the central controlled mobile communication wireless channel allocation of this employing structural approach.80RNC management and control a plurality of sub-districts (as among 2 figure 90,92,94), when mobile subscriber MS in each sub-district (in as 2 figure 54,62,72) needs to send data, they will send channel assignment request to its relevant base station (in as 2 figure 50,60,70) separately.Each base station reports 80RNC with its request, and will send travelling carriage to from the channel resource that 80RNC distributes.
The present invention has provided a kind of new distribution method based on the time-frequency two-dimensional channel resource, can be used for single sub-district and many cell conditions: Radio Resource centralized control, mixed allocation transmission channel.Dynamically adjust each local resource and satisfy symmetry and non-symmetrical service demand.
The process of its work can describe with Fig. 3.
At first 120 radio network controllers are collected all base station transmits business information that comprise 110 base stations; Mutual definite sub-district busy channel resource by 130 information.120 radio network controllers are set up and the maintenance channel resource allocation table.Which cell uplink business is which resource of this form stores be used to, and which cell downlink business is which resource be used to, and which resource does not have data such as occupied.The channel resource of some frequencies and time slot is fixed and distributes to all sub-districts; The channel resource of other frequencies and time slot is dynamically allocated to each sub-district.Simultaneously, each cell base station is also distributed to the channel information of this sub-district by 130 acquisitions.
We are divided into the time-frequency piece (being called for short TFB) that can be used for Channel Transmission with time slot and frequency range.A TFB can comprise a plurality of mark spaces and a plurality of subcarrier bandwidth.When one 100 travelling carriage needed transport service, this 100 travelling carriage can send 140 traffic channel request to 110 base stations.110 base stations send 150 channel assignment request according to the channel operating position of this sub-district to 120 radio network controllers, and 120 radio network controllers inquiry Radio Resource channel behaviour in service assigns a time-frequency piece as transmission channel in the dynamic assignment zone.Then, 120 radio network controllers send 160 channel confirmations to 110 base stations, revise the channel resource allocation table simultaneously.110 base stations confirm that according to 120 radio network controllers 170 assign the Traffic Channel of a certain time-frequency piece (TFB) as 100 travelling carriages.
When a plurality of users carried out traffic channel request simultaneously, RNC will be according to the priority of mobile subscriber in each base station, QoS, and type of service, factors such as service traffics sort; Then, assign corresponding time-frequency piece for them in proper order by it again.
The information distribution of the every frame of the inventive method and form can illustrate with Fig. 4.One frame channel resource comprises fixed resource range of distribution and variable resource allocation zone two parts.The inventive method is, with several time-frequency pieces of the front portion in the frame and two part time slots of several time-frequency pieces of rear portion and the frequency resource channel resource as fixed allocation.Wherein previous section time slot and fixed-frequency are used for the downlink channel transmission signals, and aft section time slot and fixed-frequency are used for the uplink channel transmission signal.
These fixed channels generally are used to propagate control information, as the frame head sign, and synchronizing signal, the position of conversion point indication between the descending and up channel, broadcast system information, pilot signal and control information indication etc.One frame is except the fixed resource range of distribution, and other time slot and frequency are to belong to the variable resource allocation zone.In this zone, each time-frequency piece can dynamically be distributed and be adjusted.They both can be allocated to the channel that is used for up link, also can be distributed into to be used for descending channel.
In same time slot, some frequencies can be allocated for up channel, and other frequencies can be allocated for down channel.The channel in variable allocation zone generally is used to transport service information and control signaling (as training sequence, power control information, and other control information indications etc.).Need to be provided with transfer point between the time slot of down channel and up channel, it can be set in any frequency and the interior variation of time slot in the Variable Area.If transfer point is through one or multi-slot, these time slots are called the conversion time slot.Respectively there is a protection (to be called for short GP) at interval in the both sides of conversion time slot.If a transfer point is arranged between two time slots, we only need a protection at interval.The limited size of protection interval GP is in the size of radius of society.
Time-frequency piece (TFB) in the dynamic assignment zone passes through its position, is divided into up TFB and descending TFB two parts.In the variable resource allocation scope, the TFB that is in conversion time slot front is used for downlink transmission; The TFB that is in conversion time slot back is used for ul transmissions.In the conversion time slot, the TFB that is positioned at transfer point one side can be used for up, and opposite side just can be used for descending.For example, in Fig. 4, the TFB that is positioned at above the transfer point is used for uplink signal transmissions, and the TFB that is positioned at below the transfer point is used for the downstream signal transmission; Or be positioned at TFB below the transfer point and be used for uply, the TFB that is positioned at above the transfer point is used for descending.
For a sub-district, descending TFB will be arranged in different time slots with up TFB.On a time slot, a part of TFB is as being arranged for transmitting uplink signals, and the TFB of other parts just can not be arranged for transmitted downlink signal.Otherwise TFB is as being arranged for transmitting uplink signals, and the TFB of other parts can not be arranged for transmitted downlink signal.
For different sub-districts, on a time slot, a part (or all) TFB can be used to transmit the upstream data of some sub-districts, and another part (or all) TFB can be used to transmit the downlink data of other sub-district.
A TFB piece can be transmitted information simultaneously by a plurality of sub-districts.But require a TFB in a frame, can only transmit the signal of a direction.That is to say, in many cell environments, for a TFB or transmission upward signal, or transmission of downlink signal.Do not allow in a TFB, some sub-districts are with its transmission upward signal the time, exist other sub-district with this TFB transmission of downlink signal.
In the variable resource allocation zone; if last time slot contains the TFB of transmission of downlink signal; current time slots contains the TFB that transmits upward signal; so; in order to reduce influencing each other between upward signal and downstream signal; and satisfy the requirement of the maximum transmission distance of sub-district, between these two time slots, just need certain protection (GP) at interval.The size of GP has determined the area of sub-district.During GP, base station and travelling carriage do not send signal, and they only are in receiving state signal.
In transmission course, the variation of position of conversion point can determine to be used for the ratio of the TFB quantity of ul transmissions TFB quantity and downlink transmission between up TFB and the descending TFB signal.Can distribute up channel and down channel according to the different business quantitative changeization.Therefore, between different frames, the variation that is used for the TFB quantity of down channel and is used for the TFB quantity of up channel can be satisfied the requirement of the different situations of transmission symmetry and non-symmetrical service.
This mixed channel allocation algorithm can be further described with Fig. 4.The channel code of each sub-district and employed communication channel resource conditions all are recorded in the radio channel resource allocation list.This table is also being stored the position of uplink and downlink transfer point.The local resource forms of distribution that three kinds of transfer points are arranged: when Fig. 4 represented to adopt the method Resources allocation of being invented, transfer point took the different time-gap sight; Transfer point takies a plurality of time slots such as Fig. 4 (a), and transfer point takies a time slot such as Fig. 4 (b), and transfer point does not take time slot such as Fig. 4 (c).
If configuration is finished in K sub-district of RNC condominium reason when the personal identification code of each sub-district can be set up in the sub-district, (channel code of 1≤k≤K) is Ck as the k sub-district.T time slot arranged, the F sub-frequency bands in each frame.Wherein the scope of variable time slots i is I

RNC (or by the base station BS application, RNC confirms mode) can arrange its each cell channel according to following method according to the resource requirement situation in the frame.
1) determines position and the up time-frequency piece and the down time-frequency piece scope of each cell channel fixed allocation.
2), determine variable transfer point best between up time-frequency piece and the down time-frequency piece according to the channel demands of each sub-district.
3) if a plurality of user proposes professional transmission request in a frame, RNC presses its priority, qos requirement, and type of service, indexs such as service traffics sort to these requests.The request that comes the front is handled earlier.If have only a user to propose channel request, then directly carry out 4).
4) in channel resource uplink and downlink resource dynamic range of distribution, the time-frequency piece of variable relatively transfer point diverse location is used to transmit the signal of different directions.
In the uplink and downlink variable range of a frame, the left side of transfer point (anterior time slot) and top (greater than the subcarrier of transfer point) TFB are as down-chain resource; The right of transfer point (rear portion time slot) and following (less than the subcarrier of transfer point) TFB are as uplink resource.(annotate: the following opposite TFB of arrangement resource also can on the transfer point.)
5) for a sub-district, the down time-frequency lattice should be arranged in different time slots with up time-frequency lattice.If on a time slot, a part of time-frequency piece is arranged for transmitting uplink data, for reducing to disturb, another part time-frequency lattice preferably need not, promptly should not be arranged for downlink data transmission.Vice versa.
6) for different sub-districts, if on a time slot, a part of TFB is used to transmit the upstream data of some sub-districts, and the TFB that is positioned at the opposite side of transfer point can be arranged for transmitting the downlink data of other sub-district.Vice versa.
7) channel resource that distributes each sub-district to take.And allocation result is recorded in the allocation of radio resources table.
8) when the next frame channel resource allocation, repeat 2)-7) process.
The resource distribution table can be described with Fig. 6 in the radio network controller resource management device.It has write down each local resource operating position TFB parameter list.The radio-resource-configuration table comprises 600 gauge outfits, contents such as 660 resource occupation situations and 680 explanation of tables.
600 gauge outfits comprise system parameters (for example: the distribution of time-frequency piece and quantity, uplink and downlink TFB transfer point).
660 resource operating positions comprise the channel code distribution, and occupancy is writing down the behaviour in service of time-frequency piece, comprise the sub-district of using the time-frequency piece, transmission direction (upstream or downstream), fixed area or Variable Area.
680 form data comprise form formulation and modification time, maintenance information etc.
The present invention is at first disposed the fixed channel resource of each sub-district by RNC, as the channel code of each sub-district, frame head, broadcast message, public resources such as access way.Then, according to parameters such as business throughput and types of service, calculate and add up each cell uplink and down channel demand.At up time-frequency piece of variable channel range of distribution Preliminary division and down time-frequency piece scope of resource.Arrange the up channel of each sub-district and the time-frequency piece of down channel.
In the assigning process of RNC, at first initialization process is carried out in each sub-district, then according to the time-frequency piece in each Zone situation arrangement dynamic area to each cell channel; Be used for up link to distinguish which resource, which resource is used for down link.When a user sends traffic channel request in the base station cell, arrange its channel according to following method.
