Abstract
The invention discloses a method for allocating multiplexed uplink resources in a radio relay system. The method comprises the following steps that: A, a base station computes the priorities of each base station service user and each relay user after multiplexing on each resource block according to a priority standard to form a priority matrix; B, the base station selects a matrix element with the maximum value from the priority matrix; C, the base station allocates the resource blocks to the base station user and the relay user, and selects suitable modulation coding formats for the two users according to mutual interference between the base station user and the relay user and the respective channel condition on the resource blocks; D, when a fixed bandwidth transmitting mode is used, the base station deletes the element from the priority matrix; and E, the step B to the step D are repeated until the all resource blocks are allocated. By the method, the overall interference level in a cell can be reduced and the throughputs of the system and edge users can be improved.
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, for be the operative scenario of the user of base station service and the multiplexing upstream frequency resource of user of relay services in wireless relay system.
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 Generation Mobile Communication System IMT-Advanced (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 once having formulated the in the industry cycle 3GPP of 3G UMTS technical standard with strongest influence power (3th Generation Partnership project), launched LTE-Advanced standard process in March, 2008.A characteristic of LTE-A system is in system, to have 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 customer service in the coverage of wireless relay system small area, community and user distribution, one or more relaying can be set in community, increase the throughput of the covering Jian Huo community of community with this.The cell structure of a relaying enhancement mode as shown in Figure 1.Conventionally, in order to improve the availability of frequency spectrum of system, base station service-user adopts identical frequency resource to carry out up transmission with relay services user, and in a sector, the service-user of different relayings, because close together, phase mutual interference are larger, thereby adopts the resource distribution mode of frequency division multiplexing.As shown in Figure 1, the service-user of the 1 li of relaying 1 in sector (
in region) acquisition frequency resource f1, the service-user of relaying 2 (
in region) acquisition frequency resource f2, the service-user of base station (
in region) frequency resource that takies is f1+f2.
As shown in Figure 1, due to base station service-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 are just each the other side's interference source.The uplink interference maximum that user in base station and relaying coverage boundary produces the other user, its jamproof ability is also the most weak simultaneously.The two parties dividing frequency resource of how reasonably to give multiplexed resource, reach the object of coordinating the mutual interference of both sides' phase, thereby entirety reduces system interference level, 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 community, the throughput of raising system and edge customer, is an inevitable problem in wireless relay system.
The resource regulating method of the existing two parties for resource multiplex has two kinds, and one is dispatching method independently, and the two parties that is resource multiplex is carried out respectively independently scheduling of resource and is its selection modulating-coding form independently.Another kind is to be first that a side user carries out scheduling of resource and selects modulating-coding form, again another user side carried out to 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 the first independently resource regulating method, because give no thought to the disturbed condition between the two parties of resource multiplex, so may cause two multiplexing same Resource Block of mutual strongly disturbing user, cause the sharply decline of two parties communication quality.In addition,, due to the disturbed condition of not considering between the resource multiplex two parties that will occur, both sides independently Adaptive Modulation and Coding format technology validity reduce greatly.
Adopt the second resource regulating method, can only consider the interference of first dispatched users to rear dispatched users, and there is no to consider the interference of rear dispatched users to first dispatched users, the channel quality that causes first dispatched users subsequently dispatched users difference and change, cannot select suitable modulating-coding form, reduce the validity of Adaptive Modulation and Coding technology.
From analysis above, existing resource allocation scheduling technology did not consider the mutual disturbed condition between will the two parties of multiplexed resource before dispatching, thereby can not coordinate the phase mutual interference between two parties, can not make interference level in community drop to minimum.
