Description
Technical field
The present invention relates to the wireless relay technology, particularly a kind of resource allocation methods, user scheduling method and device thereof, equipment.
Background technology
In order to tackle the wireless propagation environment of various complexity, solve following LTE (Long Term Evolution, Long Term Evolution) covering problem of network design, 3GPP (3rd Generation Partnership Project, the 3rd generation partner plan) has carried out standardization to relaying (Relay) node in LTE-Advanced R10 release protocol.By between macro base station and user terminal, adding a via node, as shown in Figure 1, the link that direct transfers between macro base station and the terminal is divided into two sections: the Radio Link between macro base station and the relaying is called return link (Un interface), and the Radio Link between relaying and the terminal is called access link (Uu interface).By via node is reasonably disposed, two sections links after the fractionation can both have the propagation distance shorter than the link that direct transfers, shelter in the round also can reduce simultaneously, and two sections links after feasible the fractionation all have the transmittability than better radio propagation conditions of the link that direct transfers and Geng Gao.
The main feature of via node comprises:
Wireless backhaul is provided, can effectively expands covering, solve the deficient problem of fiber resource, dispose flexible and introduce via node with wireless backhaul function.
Solution covers and strengthens, and can eliminate the shade overlay area that the pile group is produced by introducing via node, or even the dead band, has promoted the covering power of base station.
Yet existing above-mentioned network configuration exists at least because the problem that the less throughput that causes of the resource that access link distributes descends is described in detail as follows.
In the LTE system, it is that (relaying has independently sub-district PCI to Type I Relay that the typical case of via node realizes, can be understood as relaying is an independently sub-district), RN forwards the data to the subscriber equipment that it is served by access link (Access Link) subframe again by the data of return link (Backhaul Link) subframe reception from base station (DeNB).On the Backhaul subframe, RN is in accepting state, do not send data, and on the Access subframe, RN is in transmit status, does not receive data, and promptly the Backhaul subframe of RN and Access subframe are the quadrature time-divisions.
Because the existence of a plurality of RN, in order to guarantee the abundance of Backhaul resource, when the base station may need to the bigger Backhaul number of sub frames (such as 6) of RN configuration, in this case, just only remaining 4 of the Access subframes of each RN.
And the less downlink data that will cause sending to UE of sub-frame resources that access link distributes is deposited in the RN place, cause the decline of handling up of system, particularly for the user who is in the RN edge, because its signal to noise ratio is lower, can only use lower MCS, thereby need to consume more Access link resource, so the phenomenon that the less downlink data that is sent to UE that causes of sub-frame resources that distributes owing to access link is deposited in the RN place is more obvious.

Embodiment
In the resource allocation methods of the embodiment of the invention, user scheduling method and device thereof, the equipment, a plurality of via nodes are divided at least two via node groupings, the sub-frame resources that is used for first link then at least for described two via node packet allocation, wherein, there is the different via node grouping of the sub-frame resources that is used for first link that is assigned at least in described two via nodes grouping, guaranteeing under the constant situation of average Backhaul resource that RN is assigned to, improve the Access sub-frame number that RN can use, therefore can improve the throughput of system.
A kind of resource allocation methods of the embodiment of the invention is used for a base station, and described base station is connected with a plurality of via nodes by first link, and described a plurality of via nodes are connected with subscriber equipment by second link, and as shown in Figure 1, described resource allocation methods comprises:
In the resource allocation methods of the embodiment of the invention, a plurality of via nodes are divided at least two via node groupings, the sub-frame resources that is used for first link then at least for described two via node packet allocation, wherein, there is the different via node grouping of the sub-frame resources that is used for first link that is assigned at least in described two via nodes grouping, guaranteeing under the constant situation of average Backhaul sub-frame resources (sub-frame resources that is used for first link) that RN is assigned to, improve the Access subframe that RN can use (subframe that is used for second link between RN and the subscriber equipment) quantity, therefore can improve the throughput of system.
The throughput that can improve system to above resource allocation methods illustrates as follows.
Suppose and have 4 RN in the system, the base station is 6 to the bigger Backhaul number of sub frames of RN configuration, and just the average Backhaul number of sub frames of each RN distribution is 1.5, according to the method for salary distribution of prior art, as shown in Figure 3, each RN has only 4 Access subframes.
And according to the method for the embodiment of the invention, a plurality of via nodes are divided at least two via node groupings, and when Resources allocation, guarantee to exist the different via node grouping of the sub-frame resources that is used for first link that is assigned to improve the Access sub-frame number that RN can use, can improve the throughput of system, be described as follows with different examples.
＜example 1 〉
Be divided into 2 groupings, RN1 and RN3 are a grouping, and RN2 and RN4 are a grouping, packet allocation to 3 subframe at RN1 and RN3 place wherein, be respectively 0,1 and 2 work song frames, and packet allocation to 3 subframe at RN2 and RN4 place is respectively 3,4 and 5 work song frames.
As shown in Figure 4, wherein, the average Backhaul number of sub frames that RN distributes is 1.5 and remains unchanged, but because grouping 1 is different with 2 subframes that are assigned to of dividing into groups, so RN1,2,3 and 4 quantity that can be used for the subframe of Access link are increased to 7, with respect to 4 increases greatly of prior art.
As shown in Figure 3, the method of salary distribution of the prior art causes all RN to use identical Access subframe, the signal that RN of meeting sends when transmission can cause interference to the subscriber equipment that belongs to other RN like this, and the signal that sends as RN1 can cause interference to the subscriber equipmenies of RN2,3 or 4 services.
And as shown in Figure 4, the RN of grouping in 1 is when utilizing subframe 3,4 and 5 to transmit, because the RN in the grouping 2 is in accepting state, does not send data, so can not bring interference to the subscriber equipment of the RN service in 1 of dividing into groups.Equally, the RN of grouping in 2 because the RN in the grouping 1 is in accepting state, do not send data when utilizing subframe 0,1 and 2 to transmit, so can not bring interference to the subscriber equipment of the RN service in 2 of dividing into groups.
Therefore, the method for the embodiment of the invention can't be brought extra interference between the grouping when increase RN can be used for the sub-frame number of Access link.
＜example 2 〉
Be grouped into example to be divided into 4, RN1, RN2, RN3 and RN4 belong to a grouping separately, and wherein the subframe that arrives of the packet allocation at place is as follows separately for RN1, RN2, RN3 and RN4:
0,1 work song frame;
2 work song frames;
3,4 work song frames;
5 work song frames.
As shown in Figure 5, wherein, the average Backhaul number of sub frames that RN distributes is 1.5 and remains unchanged, but because grouping 1,2,3 and 4 subframes that are assigned to are different, so can being used for the quantity of the subframe of Access link, RN1,2,3 and 4 is increased to 8,9,8 and 9 respectively, with respect to 4 increases greatly of prior art.
Simultaneously, can also reduce interference, be explained as follows subscriber equipment.
As shown in Figure 3, the method of salary distribution of the prior art causes all RN to use identical Access subframe, the signal that RN of meeting sends when transmission can cause interference to the subscriber equipment that belongs to other RN like this, and the signal that sends as RN1 can cause interference to the subscriber equipmenies of RN2,3 or 4 services.
And as shown in Figure 4, the RN of grouping in 1 is when utilizing subframe 3,4 and 5 to transmit, because the RN in the grouping 2 is in accepting state, does not send data, so can not bring interference to the subscriber equipment of the RN service in 1 of dividing into groups.Equally, the RN of grouping in 2 because the RN in the grouping 1 is in accepting state, do not send data when utilizing subframe 0,1 and 2 to transmit, so can not bring interference to the subscriber equipment of the RN service in 2 of dividing into groups.
Therefore, the method for the embodiment of the invention can't be brought extra interference between the grouping when increase RN can be used for the sub-frame number of Access link.
＜example 3 〉
Be grouped into example to be divided into 3, RN1 belongs to a grouping, and RN2, RN3 and RN4 belong to a grouping, and wherein the subframe that arrives of the packet allocation at the grouping at RN1 place and RN2, RN3 and RN4 place is as follows:
0,1 work song frame;
2,3,4 and 5 work song frames.
As shown in Figure 6, wherein, the average Backhaul number of sub frames that RN distributes is 1.5 and remains unchanged, but because grouping 1 and 2 subframe that is assigned to is different, so can being used for the quantity of the subframe of Access link, RN1,2,3 and 4 is increased to 8,6,6 and 6 respectively, with respect to 4 increases greatly of prior art.
From above all examples, utilize the method for the embodiment of the invention, a plurality of via nodes are divided at least two via node groupings, and when when Resources allocation, guarantee having the different via node grouping of the sub-frame resources that is used for first link that is assigned to, can be when guaranteeing that the average Backhaul sub-frame number of RN is constant, increase the quantity of the subframe that is used for the Access link of RN, therefore improved the throughput of system.
Certainly, in the above example, different grouping has all been distributed different Backhaul subframes, but should be understood that, different groupings also can distribute identical Backhaul subframe, as long as guarantee to have two packet allocation to different Backhaul subframes, with Fig. 5 is example, also can be that grouping 1 is assigned to 0,1 work song frame, and grouping 2 is assigned to 2,3 and 4 work song frames, grouping 3 is assigned to 2,3 and 4 work song frames, and divides into groups 4 to be assigned to 5 work song frames.
In each above-mentioned example, as long as a plurality of via nodes are divided at least two via node groupings, and when when Resources allocation, guarantee having the different via node grouping of the sub-frame resources that is used for first link that is assigned to, can be when guaranteeing that the average Backhaul sub-frame number of RN is constant, increase the quantity of the subframe that is used for the Access link of RN, but can find from above example, when in a grouping, having a plurality of RN, the subframe that is used for the Access link of the RN of RN packets inner is identical, therefore, can cause certain interference to the subscriber equipment of service each other each other.
In order to reduce this interference, in specific embodiments of the invention, this resource allocation methods also comprises:
Obtain the positional information of described a plurality of via nodes;
Divide into groups according to described positional information in the described step that described a plurality of via nodes is divided into the grouping of at least two via nodes, wherein, in described at least two via nodes grouping, the distance between the included via node of each via node grouping is greater than default thresholding.
With network environment shown in Figure 6 is example, comprising 4 RN, for: RN1,2,3 and 4, in specific embodiments of the invention, suppose that 2 RN are divided into 1 group, then grouping can be following various situations:
One group of RN1 and RN2, one group of RN3 and RN4;
One group of RN1 and RN3, one group of RN2 and RN4;
One group of RN1 and RN4, one group of RN2 and RN3.
When one group of RN1 and RN2,, so will inevitably be subjected to the interference of the downstream signal that RN2 sends among Fig. 6 by the user equipment (UE) 1 of RN1 service because its distance is more approaching;
And as one group of RN1 and RN4, because its distance is more approaching, therefore it is less to be subjected to the interference of the downstream signal that RN4 sends by the user equipment (UE) 1 of RN1 service among Fig. 6, but, so will inevitably be subjected to the interference of the downstream signal that RN3 sends among Fig. 6 by the user equipment (UE) 2 of RN2 service because the distance of RN2 and RN3 is more approaching.
Consider above situation, in order to reduce this interference, in specific embodiments of the invention, RN1 and RN3 are divided into one group, RN2 and RN4 are divided into one group, and then the RN phase mutual edge distance in each grouping is all distant, then also corresponding the reducing of the interference that subscriber equipment brought that the other side is served.
And, can reduce this interference greater than default thresholding as long as guarantee the distance between the interior via node of each grouping from the specific implementation angle.
Certainly, various possible compound modes have more than been enumerated, but in the grouping process of reality, it is also conceivable that the traffic carrying capacity of via node, that is to say, in the step of the first link assignment sub-frame resources that is described at least two via nodes grouping, carry out sub-frame resources according to the traffic carrying capacity summation of the included via node of each via node grouping in described at least two via nodes grouping and distribute.
Illustrate as follows.
With network environment shown in Figure 6 is example, comprising 4 RN, for: RN1,2,3 and 4, in specific embodiments of the invention, suppose one group of RN1 and RN3, one group of RN2 and RN4; If the traffic carrying capacity summation of RN1 and RN3 is the twice of the traffic carrying capacity summation of RN2 and RN4, then 4 subframes can be distributed to the combination at RN1 and RN3 place, and 2 subframes be distributed to the combination at RN1 and RN3 place.
Certainly, more than only be the criterion that illustrates a kind of sub-frame allocation, do not represent the embodiment of the invention to only limit to the above-mentioned method of salary distribution.
In the resource allocation methods of the embodiment of the invention, the described sub-frame resources allocation result corresponding with each first via node comprises the sub-frame resources information that described first via node self is assigned to, and belong to the grouping of different via node with described first via node, and the sub-frame resources information that the second different via node of the sub-frame resources that is used for first link that distributes is assigned to, make the via node of winning can be preferentially with in the subscriber equipment of service to the higher dispatching user facility of the interference sensitivity of described second via node on first sub-frame resources, wherein: described first sub-frame resources be distribute to described second via node the sub-frame resources that is used for first link partly or entirely.
Above-mentioned advice method can reduce the interference to subscriber equipment, improves the performance of subscriber equipment, will be elaborated below.
The embodiment of the invention also provides a kind of user scheduling method, be used for one first via node, described first via node is connected with subscriber equipment by second link, described first via node is connected with the base station by first link, wherein, the sub-frame resources that is used for first link of described via node obtains according to above-mentioned resource allocation methods distribution, and described base station also is connected with second via node, described first via node belongs to different via node groupings with second via node, and the sub-frame resources difference that is used for first link of distributing, described user scheduling method comprises as shown in Figure 8:
Above-mentioned interference sensitivity can characterize by various parameters, and as RSRP, SINR, CQI etc., it belongs to the category of prior art, is not described in detail at this.
Can reduce interference by above-mentioned method, be described in detail as follows the user.
Utilize the method for the embodiment of the invention to carry out after the resource allocation,, suppose one group of RN1 and RN3 in conjunction with situation shown in Figure 7, one group of RN2 and RN4, and resource allocation as shown in Figure 4, can find, be example with RN1 this moment, when a user is dispatched to subframe 6,7,8 or 9, can be subjected to RN2,3 and 4 interference simultaneously, and the user is dispatched to subframe 3,4 or at 5 o'clock, then only can be subjected to the interference of RN2, and because RN1 and RN2 distance are far away, so this interference is also less relatively.
According to above-mentioned explanation, in specific embodiments of the invention, with RN1 is example, can find from scheming to go up signal, UE1 is a Cell Edge User, and UE3 is a Cell Center User, so UE1 will be higher than the interference sensitivity of UE3 to second via node to the interference sensitivity of second via node, so in user's scheduling, can preferentially UE1 be dispatched on subframe 3,4 and/or 5, because on subframe 3,4 and 5, RN2 is in accepting state, can not send signal, can not bring interference to UE2.
And for this Cell Center User of UE3, at first be distant with RN2 distance, it is more intense that another receives the signal of RN1, so RN2 brings interference also can to eliminate preferably to UE3, can not bring very big influence to UE3.
