As depicted in figs. 1 and 2, the network architecture schematic diagram of LTE system and LTE-Advanced system is respectively.In LTE system, base station (BS, Base Station) is communicated by S1 interface with between equipment of the core network, is communicated between base station by X2 interface; In LTE-Advanced system, communicated by S1 interface between base station with equipment of the core network, communicated by X2 interface between base station, by Un interface communication between relaying and base station.
That LTE system access technology adopts is OFDM (OFDMA, Orthogonal FrequencyDivision Multiple Access) technology, when the network planning, division of resources is carried out in advance for each base station, be each base station assigns initial resource, comprise each initial resource block in the initial resource of each base station, the initial resource at adjacent base station edge is mutually orthogonal.Resource needed for user is by base station centralized distribution, when needing certain user resource allocation for self-management, base station first judges whether also have assignable resource in the initial resource of self, if do not have, namely the initial resource block that initial resource comprises can not meet the needs of user, now this base station is in heavy duty state, then X2 interface is passed through in this base station, high interference designator (HII is sent to adjacent base station, High Interference Indicator), represent the initial resource block used in the initial resource of adjacent base station, after adjacent base station receives HII, just should avoid as self-administered user distributes this Resource Block used, or reduce the interference of this Resource Block as far as possible, thus the resource multiplex realized between base station.(represent that the Resource Block used by HII there occurs collision) when base station detects that the interference ratio that certain Resource Block is subject to is more serious, overload instruction (OI will be sent to adjacent base station, Overload Indicator) signal, indicate this Resource Block to be subjected to serious interference; Receive the interference source base station of OI signal, will control by power the transmitted power reducing interference source, realize interference coordination with this.
Introduce in the LTE-Advanced system after relaying, when the network planning, also need to carry out division of resources for each relaying in advance, be each relay distribution initial resource, each initial resource block is comprised in the initial resource of each relaying, the initial resource at adjacent relay edge is mutually orthogonal, and the resource needed for user is by relaying centralized distribution.But, the maximum difference introducing the LTE-Advanced system after relaying and LTE system is: do not have physical interface between each relaying, and only have logic interfacing, directly can not communicate, can only be communicated by the X2 interface between the wireless backhaul links (this wireless backhaul links is in a standard also referred to as Un interface) between relaying with base station and base station.Therefore, when relaying needs certain user resource allocation for self-management, if judge there is no assignable resource in the initial resource of self, namely the initial resource block that initial resource comprises can not meet the needs of user, now this relaying is in heavy duty state, then this relaying can only transmit HII signal to adjacent relay by the X2 interface between the wireless backhaul links between relaying and base station and base station, with realization using the initial resource of adjacent relay, and when the Resource Block used by HII signal is interfered, OI signal is sent to adjacent relay by identical mode, carry out interference coordination.But, transmit HII/OI signal by said method, both added propagation delay time, and too increased the expense of the wireless backhaul links be relayed between base station, and reduced the treatment effeciency of the network equipment.

Embodiment
In order in resource allocation process, reduce propagation delay time, reduce the expense of the wireless backhaul links be relayed between base station, improve the treatment effeciency of the network equipment, embodiments provide a kind of resource allocation methods, device, system and relevant device.
Below in conjunction with Figure of description, the preferred embodiments of the present invention are described, be to be understood that, preferred embodiment described herein is only for instruction and explanation of the present invention, be not intended to limit the present invention, and when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Embodiment one
As shown in Figure 3, be the implementing procedure schematic diagram of the resource allocation methods that the embodiment of the present invention provides, comprise the steps:
The resource reservation signal that the user terminal of S301, relay reception self-management sends in the predetermined resource blocks that request is predetermined, the initial resource block that the initial resource that this predetermined resource blocks is other relayings comprises;
Wherein, when the signal to noise ratio of the downstream signal of the initial resource block that this user terminal can comprise in the initial resource measuring other relayings is not less than the first default defined threshold, this initial resource block sends resource reservation signal, to make a reservation for this initial resource block to this relaying.
S302, when the resource reservation signal received meets pre-conditioned, confirm that this user terminal makes a reservation for successfully to this predetermined resource blocks;
Wherein, above-mentionedly pre-conditionedly the second default defined threshold can be not less than for the Signal to Interference plus Noise Ratio of resource reservation signal.
S303, when needs are for this user terminal Resources allocation, judge, in each initial resource block that the initial resource of self comprises, whether the quantity of assignable initial resource block is less than the 3rd default defined threshold;
If in the initial resource block of relaying, the quantity of assignable initial resource block is very few, then can think that this relaying is in heavy duty state, initial resource cannot meet the demand of the user terminal of self-management, now just needs the initial resource block of other relayings multiplexing.
S304, if the determination result is YES, then select at least one predetermined resource blocks to distribute to this user terminal from the predetermined each predetermined resource blocks of this user terminal.
In concrete enforcement, when carrying out the network planning, first carry out division of resources, namely according to the principle that the resource of adjacent relay edge distribution is mutually orthogonal, in advance whole band resource being divided into some parts, is then each relay distribution initial resource.Such as, whole band resource can be divided into four parts, and be each relay distribution initial resource according to four chromogen reasons, thus can ensure that the initial resource that adjacent relay distribution arrives is orthogonal.As shown in Figure 4, for division of resources implements schematic diagram, whole band resource is divided into F1, F2, F3 and F4 tetra-part, and according to four chromogen reasons, ready-portioned band resource is distributed to each relaying, for convenience of description, be described for 2, every sector relaying, suppose relay 1 is assigned to the initial resource of F1 part, relaying 2 is assigned to the initial resource of F2 part, and relaying 3 is assigned to the initial resource of F3 part, and relaying 4 is assigned to the initial resource of F4 part.Like this, for relaying 1, initial resource block is the Resource Block comprised in initial resource; The Resource Block that the initial resource that predetermined resource blocks comprises relaying 2, relaying 3, relaying 4 are assigned to comprises
In the embodiment of the present invention, if each relay distribution to initial resource cannot meet the demand of the user terminal of self-management time, use by resource reservation mode the resource that other relay distribution arrive.Because relaying can use the resource of adjacent relaying, therefore, the situation of predetermined resource collision may occur, and based on this, the embodiment of the present invention provides a kind of resource collision treatment principle, when there is resource collision, can process, be specially according to this principle:
When detecting that the Signal to Interference plus Noise Ratio of downstream signal of the Resource Block distributed for user terminal is less than the 4th default threshold value, whether the Resource Block judging to distribute to this user terminal is initial resource block that the initial resource of self comprises;
If the determination result is YES, then the signal transmitting power to this user terminal is increased;
If judged result is no, then each initial resource block comprised from the initial resource of self and this user terminal make a reservation for, successful each predetermined resource blocks, select at least one Resource Block to be reassigned to this user terminal.
For the ease of understanding, being that the implementation process of the user terminal Resources allocation of self-management is that example is described below by way of relaying 1, as shown in Figure 5, comprising the steps:
The downlink signal quality of each initial resource block that the initial resource of S501, user terminal measurement other relayings except service relay comprises;
The process that user terminal carries out resource reservation can be divided into three time slots and complete, concrete, in first time slot, this user terminal measurement other band resources except the F1 that relaying 1 is assigned to, the i.e. quality of the downstream signal of each initial resource block that comprises of F2, F3 and F4, concerning this user terminal, each initial resource block that F2, F3 and F4 comprise is the predetermined resource blocks that it can be predetermined.
S502, when the downlink signal quality measuring certain predetermined resource blocks exceedes the first default defined threshold, this predetermined resource blocks sends resource reservation signal;
Concrete, in second time slot, if when this user terminal measurement exceedes to the downlink signal quality (i.e. the signal to noise ratio of the downstream signal of this predetermined resource blocks) of certain predetermined resource blocks the first defined threshold pre-set, i.e. broadcast transmission resource reservation signal in this predetermined resource blocks, represents this Resource Block predetermined.Suppose that this user terminal needs the Resource Block that comprises of the f2 of predetermined frequency band resource F2 part, the Resource Block that the f4 part of the Resource Block that the f3 part of band resource F3 comprises and band resource F4 comprises.
In concrete enforcement, due to user terminal broadcast transmission resource reservation signal, like this, the service relay of self can receive the resource reservation signal of this user terminal transmission, and other adjacent relaying also can receive the resource reservation signal that this user terminal sends.It can thus be appreciated that the service relay of this user terminal also may receive the resource reservation signal to same Resource Block of the user terminal transmission of adjacent relay management.
The service relay of S503, this user terminal calculates the Signal to Interference plus Noise Ratio of the resource reservation signal received;
Concrete, the service relay of this user terminal is according to the resource reservation signal to same predetermined resource blocks received, the resource reservation signal sent by the user terminal of self-management is as useful signal, the resource reservation signal of the user terminal transmission of other relaying is as interference signal, calculate the Signal to Interference plus Noise Ratio of the resource reservation signal received, when the Signal to Interference plus Noise Ratio calculated is not less than the second defined threshold pre-set, determine that this user terminal makes a reservation for successfully to this predetermined resource blocks, otherwise, make a reservation for unsuccessfully.As shown in Figure 5 a, for user terminal carries out the relation schematic diagram in resource reservation process between each time slot and frequency.
In the 3rd time slot, may there are three kinds of situations in the predetermined resource of this user terminal: 1) all make a reservation for successfully: as in Fig. 5 a, the Resource Block that f4 part comprises; 2) part makes a reservation for successfully: as in Fig. 5 a, the Resource Block that f2 part comprises; 3) all make a reservation for unsuccessfully: as in Fig. 5 a, the Resource Block that f3 part comprises.In concrete enforcement, the predetermined predetermined resource blocks of user terminal represents that the signal to noise ratio of the down channel of this predetermined resource blocks is higher, i.e. path loss and the less Resource Block of shadow fading, and the predetermined resource blocks (its Signal to Interference plus Noise Ratio accepting resource reservation signal is larger) that can make a reservation for that successful predetermined resource blocks represents that the degree of being disturbed is less.
After completing resource reservation process, the operable resource of this user terminal comprises each initial resource block that initial resource that relaying 1 allocates in advance comprises, i.e. each Resource Block of comprising of F1, and each predetermined resource blocks that predetermined successful resource comprises, the Resource Block that Resource Block, predetermined successful f2 part that namely f4 comprises comprise.
When the service relay of S504, this user terminal needs for this user terminal Resources allocation, judge, in each initial resource block that the initial resource self be pre-assigned to comprises, whether the quantity of assignable initial resource block is less than the 3rd default defined threshold; If so, then perform step S505, if not, then perform step S506;
Concrete, relaying 1 is when needs are for this user terminal Resources allocation, according to the principle of " first orthogonal rear multiplexing ", namely first judge in each initial resource block that the initial resource of self comprises, whether the quantity of assignable initial resource block is less than the 3rd default defined threshold, and wherein, the business that the 3rd defined threshold can use according to this user terminal is arranged, when the Resource Block of the service needed that user terminal uses is more, it is higher that the 3rd defined threshold can be arranged; When the Resource Block of the service needed that user terminal uses is less, it is lower that the 3rd defined threshold can be arranged.
The service relay of S505, this user terminal is this user terminal Resources allocation from predetermined successful predetermined resource blocks, and performs step S507;
Concrete, from predetermined successful predetermined resource blocks, namely from the Resource Block that f4 and predetermined successful f2 part comprise for this user distribution meets the Resource Block of its needs quantity.
The service relay of S506, this user terminal is this user terminal Resources allocation from the initial resource block that the initial resource be pre-assigned to comprises;
Concrete, from the initial resource block that preallocated initial resource comprises, namely in the Resource Block that comprises of F1 for the distribution of this user terminal meets the Resource Block of its needs quantity.
The service relay of S507, this user terminal detects the Signal to Interference plus Noise Ratio distributing to the Resource Block of this user terminal;
The service relay of S508, this user terminal judges that whether the Signal to Interference plus Noise Ratio detected is lower than the 4th defined threshold preset, and if so, then perform step S509, if not, flow process terminates;
Concrete, when relaying detects that the Signal to Interference plus Noise Ratio of the downstream signal of the Resource Block that the user terminal for self-management distributes is less than the 4th default defined threshold, this illustrates that there occurs predetermined resource collides.
The initial resource block that the initial resource whether Resource Block that the service relay of S509, this user terminal judges to distribute to this user terminal is further assigned to for self comprises, if so, then performs step S510, if not, then performs step S504;
The service relay of S510, this user terminal increases the signal transmission power to this user terminal.
Concrete, if the initial resource block that the initial resource that the Resource Block judging to distribute to this user terminal is assigned to for self comprises, illustrate that the Resource Block that this user terminal is using is used by the user terminal of other relaying, and the user terminal of self-management receives strong jamming, this situation, the service relay of this user terminal can be controlled by power, increases the signal transmission power to this user terminal.
In concrete enforcement, if during the Resource Block that the Resource Block judging to distribute to this user terminal is not the initial resource self be assigned to be comprised, illustrate this user terminal using predetermined successfully, other relay distribution to the Resource Block that comprises of initial resource, and oneself receives interference, now, each initial resource block that the service relay of this user terminal should comprise from the initial resource of self and this user terminal make a reservation for successful each predetermined resource blocks, reselect meet this user terminal quantity required resource block assignments to this user terminal.
From said process, in the embodiment of the present invention, when the service relay of user terminal is in heavy duty state, service relay will make a reservation for successful predetermined resource blocks for user terminal distributes this user terminal, realize using the Resource Block of adjacent relay with this; When the Resource Block distributing to this user terminal is interfered, the initial resource block comprised in the initial resource of the Resource Block that first service relay judges to distribute to this user terminal whether for self, if, increase the signal transmission power to this user terminal, otherwise, service relay redistributes Resource Block for this user terminal, interference coordination is realized with this, and without the need to transmitting HII/OI signal between relaying, thus decrease propagation delay time, reduce the expense of the wireless backhaul links between relaying and base station, improve the treatment effeciency of the network equipment.
As shown in Fig. 5 b, Fig. 5 c and Fig. 5 d, the relation schematic diagram that the user terminal being respectively the management of relaying 2, relaying 3 and relaying 4 carries out in resource reservation process between each time slot and frequency, the process that certain user terminal of the implementation process and relaying 1 of carrying out Resourse Distribute due to each relaying carries out Resourse Distribute is identical, repeats no more here.As depicted in fig. 5e, be that the user terminal of four groups of relay management carries out in resource reservation process, the schematic three dimensional views of the relation between relaying, time slot and frequency.
