Description
Technical field
The invention belongs to wireless communication technology field, relate to a kind of resource allocation methods, relate in particular to the uplink resource allocating method of resource multiplex in a kind of wireless relay system.The face the future relaying enhancement mode transmission technology of mobile communication system of the present invention, at be the operative scenario of the multiplexing upstream frequency resource of user of the user of base station services in the wireless relay system and relay services.
Background technology
As current communications field development potentiality maximum, the mobile communication technology that market prospects are the widest has welcome the 3G epoch.But in order to solve frequency spectrum resource anxiety, power system capacity is limited, user's request is growing problem, International Telecommunication Association's tissue has started the technology collecting work of the 4th IMT-Advanced of third-generation mobile communication system (ITU) in February, 2008.In order to respond the technology collection of ITU-R IMT-Advanced (International MobileTelecommunications-Advanced), also be unwilling to remain out of the limelight as the 3GPP that had once formulated 3G UMTS technical standard in the industry cycle with strongest influence power (3th Generation Partnership project), launched the LTE-Advanced standard process in March, 2008.A characteristic of LTE-A system be in system, introduced via node (Relay station, RS/RN).The introducing of relay station has improved covering quality, the coverage of signal to a certain extent, improves power system capacity.
According to the coverage of sub-district in the wireless relay system, customer service and user distribution in the sub-district, one or more relaying can be set in the sub-district, hold concurrently or the throughput of sub-district with this covering that increases the sub-district.The cell structure of a relaying enhancement mode as shown in Figure 1.Usually, in order to improve the availability of frequency spectrum of system, base station services user adopts identical frequency resource to carry out up transmission with the relay services user, and the service-user of different relayings thereby adopts the resource distribution mode of frequency division multiplexing because close together, phase mutual interference are bigger in sector.As shown in Figure 1, the service-user of the 1 li relaying 1 in sector (
In the zone) acquisition frequency resource f1, the service-user of relaying 2 (
In the zone) acquisition frequency resource f2, the service-user of base station (
In the zone) frequency resource that takies is f1+f2.
As shown in Figure 1, because base station services user and the multiplexing identical upstream frequency resource f1+f2 of relay services user, therefore, the base station user of resource multiplex and trunk subscriber just become the other side's interference source each other.Be in the uplink interference maximum of the user of base station and relaying coverage boundary to the other user's generation, its anti-jamming capacity is also the most weak simultaneously.How reasonably to give the two parties dividing frequency resource of multiplexed resource, reach the purpose of coordinating the mutual interference of both sides' phase, thus the whole system interference level that reduces, and raising edge customer and throughput of system are one problem to be solved.
How to solve the base station user of uplink resource multiplexing and the resource allocation scheduling of trunk subscriber, reduce the overall interference level in the sub-district, the throughput of raising system and edge customer is an inevitable problem in the wireless relay system.
The resource regulating method of existing two parties for resource multiplex has two kinds, and a kind of is dispatching method independently, and the two parties that is resource multiplex is carried out independently scheduling of resource respectively and is its selection modulating-coding form independently.Another kind is to be earlier that a side user carries out scheduling of resource and selects the modulating-coding form, again another user side is carried out scheduling of resource and select modulating-coding form [list of references Shin-Ming Cheng, PhoneLin, Di-Wei Huang, Shun-Ren Yang, " A Study on Distributed/CentralizedScheduling for Wireless Mesh Network ", International Conference OnCommunications And Mobile Computing Proceedings 2006 (IWCMC 2006), pp.599-604,2006, Vancouver, Canada].
Adopt first kind of independently resource regulating method,,, cause the rapid decline of two parties communication quality so may cause two multiplexing same Resource Block of mutual strongly disturbing user because give no thought to the disturbed condition between the two parties of resource multiplex.In addition, owing to the disturbed condition of not considering between the resource multiplex two parties that will take place, both sides independently Adaptive Modulation and Coding format technology validity reduce greatly.
Adopt second kind of resource regulating method, can only consider of the interference of first dispatched users to the back dispatched users, and do not have to consider that afterwards dispatched users is to the interference of first dispatched users, the channel quality that causes first dispatched users subsequently dispatched users difference and change, can't select suitable modulating-coding form, reduce the validity of Adaptive Modulation and Coding technology.
By top analysis as can be known, existing resources allocation schedule technology was not taken all factors into consideration the mutual disturbed condition between will the two parties of multiplexed resource before dispatching, thereby can not coordinate phase mutual interference between the two parties, can not make that interference level drops to minimum in the sub-district.
