Description

无线资源分配方法及装置技术领域 Radio resource allocation method and apparatus TECHNICAL FIELD

[0001] 本发明涉及无线通信领域,具体而言,涉及一种无线资源分配方法及装置。 [0001] The present invention relates to the field of wireless communications, particularly, to a method and apparatus for radio resource assignment.

背景技术 Background technique

[0002] 无线通信系统中,服务质量(QoS,Quality of Service)和系统吞吐率是无线系统的两个最重要的指标。 [0002] a wireless communication system, quality of service (QoS, Quality of Service) and system throughput are two of the wireless system the most important indicators. 干扰协调是系统QoS满意度的保障,而干扰协调往往需要牺牲小区(Cell)整体吞吐率来换取Cell边缘吞吐率的提升,进而提高满足整个Cell更多UE的QoS要求,如何在QoS满足的基础上实现系统吞吐率的最大化一直都是无线通信技术研究的热点。 Interference coordination is to protect the QoS satisfaction systems, and often require the victim cell interference coordination (Cell) improve the overall throughput in exchange for Cell edge throughput, thus improving QoS to meet the requirements of the entire Cell UE's more, the foundation of how to meet the QoS maximize the system throughput has been achieved hotspot wireless communications technology.

[0003] 以长期演进(LTE,Long Term Evolution)系统为例,在LTE系统进行数据传输时,将上/下行时频域物理资源组成资源块(Resource Block, RB),作为物理资源单位进行调度与分配。 [0003] In Long Term Evolution (LTE, Long Term Evolution) system as an example, when data transmission in the LTE system, a frequency domain resource block composed of the physical resource (Resource Block, RB), as a physical resource units for scheduling when the uplink / downlink and distribution. 在常规循环前缀(Normal CP,NormalCyclic Prefix)情况下,一个资源块(RB,Resource Block)在频域上包含12个连续的子载波,在时域上包含7个连续的正交频分复用(OFDM)符号,即频域宽度为180kHz,时间长度为0.5ms。 In a normal cyclic prefix (Normal CP, NormalCyclic Prefix) case, a resource block (RB, Resource Block) contains 12 consecutive subcarriers in the frequency domain, it contains seven consecutive in the time domain Orthogonal Frequency Division Multiplexing (OFDM) symbols, i.e. the frequency domain width of 180kHz, the length of time of 0.5ms.

[0004] 在LTE上行资源分配中,基站(eNodeB)的上调度器需要为用户分配一定数量的RB、发射功率和选择恰当的调整编码方式(Modulation CodingScheme,MCS)。 [0004] In LTE uplink resource allocation, a scheduler on the base station (eNodeB) RB allocation requires certain number of users, the transmit power adjustment and selection of appropriate coding scheme (Modulation CodingScheme, MCS). 为用户分配的RB数量、发射功率、MCS、QoS与系统吞吐率之间存在着以下关系: RB is the number assigned to the user, transmit power, there is the following relationship between the MCS, QoS and system throughput:

[0005] 单个UE的总功率一定,分配的RB越多,单位RB上的功率越低,对邻区干扰越低,MCS越低,本小区吞吐率越低,该UE的QoS越容易得到满足; [0005] The total power of a single UE is constant, the RB allocation more the lower the power unit on the RB, the lower the neighboring cell interference, the lower the MCS, lower the present cell throughput, QoS of the UE is more easily met ;

[0006] 反之,可以为单个UE分配较少的RB,每个UE的可用功率增加,对邻小区干扰增加,MCS越高,本小区吞吐率越高,该UE的QoS越不容易得到满足; [0006] Conversely, fewer single UE may be assigned the RB, each of the available power of the UE is increased, interference to neighboring cells increases, the higher the MCS, this higher cell throughput, QoS of the UE are less likely to be met;

[0007] 综上LTE系统中依然没有一个很的方法解决QoS满意度与系统吞吐率的矛盾。 [0007] In summary LTE system is still no way to solve a very QoS satisfaction and system throughput of contradictions.
