- a base station refers to a device that provides services for a terminal.

Description
一种资源度量值的接收方法、 发送方法及基站和终端 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种资源度量值的接收方法、 发送方法及基站和终端。 背景技术
在无线通信系统中, 基站是指为终端提供服务的设备, 基站通过上 /下 行链路与终端进行通信, 下行或前向是指基站到终端的方向, 上行或反向 是指终端到基站的方向。 多个终端可同时通过上行链路向基站发送数据, 也可以通过下行链路同时从基站接收数据。
釆用基站调度控制的数据传输系统中, 系统所有资源的调度分配通常 行传输时所能使用的资源情况等, 这些都由基站调度分配。
在正交频分复用 ( Orthogonal Frequency Division Multiplexing , OFDM ) 系统中, 同一小区内基站与不同终端进行下行数据传输时, 由于这些下行 链路是彼此正交的, 因此可以避免小区内干扰。 然而, 不同小区之间的下 行链路可能不是正交的, 因此, 每一个终端都可能受到来自其它相邻小区 基站的下行干扰, 即小区间干扰。
降低小区间干扰对系统性能的影响是蜂窝系统设计的一个重要目标, 如果小区间的干扰严重, 则会降低系统容量, 特别是小区边缘用户的传输 能力, 进而影响系统的覆盖能力以及终端的性能。 为了克服小区间干扰, 可以釆用自适应频率重用 (Adaptive Frequency Reuse, AFR )方案, 将不同 子带资源分配给终端, 以降低小区间干扰强度。
图 1 为现有技术中相邻扇区的频率资源分配方式及各个频率分区
( Frequency Partition, FP ) 的发射功率限制情况的示意图, 如图 1所示, AFR方案的主要原理为:
首先,将可用频率资源划分为 N个 FP, N为大于零的整数,假设 N=7 , 即将可用频率资源划分为 [FPi, FP2, FP3, FP4, FP5, FP6, FP7]。 其中, FPi, FP2, FP3的频率重用因子为 3 (即 Reuse3 , 也称作 Reusel/3 ), FPl5 FP2, FP3中的 频率资源分配给三个相邻扇区中一个扇区, 而其他两个扇区不能使用该频 率资源或者需要釆用限制该频率资源的子载波发射功率的方法来使用该频 率资源; FP4, FP5, FP6的频率重用因子为 3/2(即 Reuse 3/2,也称作 Reuse2/3 ), FP4, FP5, FP6中的频率资源分配给三个相邻扇区中两个扇区, 而第三个扇区 不能使用该频率资源或者需要釆用限制该频率资源的子载波发射功率的方 法来使用该频率资源; FP7频率重用因子为 1 (即 Reuse 1 ), 三个相邻扇区 都可以使用该频率资源。
然后, 基站为每个 FP分配一个资源度量值(Resource Metric, RM ), 即 [RMi, RM 2, RM 3, RM 4, RM 5, RM 6, RM 7] , 并且将该资源度量值通知终 端, 每个终端通过测量各个 FP 的频谱效率(Spectral Efficiency, SE ), 并 且通过计算各个 FP的 nS ( nSEi = SEj/RMi, 其中 i为 FP的索引号) 的大 小, 反馈 nS 最大的 M ( M大于等于 1 )个 FP的信道质量信息 (Channel Quality Information, CQI )到基站, 基站根据终端上报的 FP的 CQI情况进 行资源分配。
最后, 基站自适应调整各个 FP的大小、 各个 FP中子载波的发射功率 及各个 FP的 RM值, 并且通知本扇区内的所有终端。 然而, 基站每次都将 所有 FP的 RM发送给终端的方式, 会明显增加系统的开销。 发明内容
