Description

频率分区的选择方法及装置 Selection means and method of frequency partitions

技术领域 FIELD

[0001] 本发明涉及通信领域,具体而言,涉及一种频率分区的选择方法及装置。 It relates to a frequency selection method and apparatus for partitioning [0001] The present invention relates to communication field, in particular.

背景技术 Background technique

[0002] 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。 [0002] In a wireless communication system, a base station refers to a device providing services to a terminal, the base station communicates the up / downlink and the terminal, before or downlink refers to a direction of the base station to the terminal, the terminal refers to the uplink or reverse direction to the base station. 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。 Multiple terminals may simultaneously transmit data to the base station through the uplink, may simultaneously receive data from the base station through a downlink.

[0003] 采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由基站进行,例如,基站进行下行传输时的资源分配情况以及终端进行上行传输时所能使用的资源情况等,这些都由基站调度分配。 [0003] Data transmission system using a base station control scheduling, a scheduling assignment of all resources is usually carried out by a base station system, e.g., resource allocation when the base station and the terminal for downlink transmission resources that can be used for uplink transmission, these scheduling assignment by the base station.

[0004] 在正交频分复用(Orthogonal Frequency Division Multiplexing,简称为0FDM) 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。 [0004] When orthogonal frequency-division multiplexing (Orthogonal Frequency Division Multiplexing, 0FDM for short) system, in the same cell base station for downlink data transmission with different terminals, since these downlink are orthogonal to each other can be avoided interference within the cell. 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。 However, the downlink between different cells may not be orthogonal, thus each terminal may be downlink interference from other base stations of the neighboring cells, i.e., inter-cell interference.

[0005] 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。 [0005] reduce inter-cell interference impact on system performance is an important design target cellular system, inter-cell interference if severe, will reduce system capacity, transmission capacity in particular cell edge users, thereby affecting the system capacity and coverage performance of the terminal. 为了克服小区间干扰,可以采用部分频率重用(Fractional FrequencyReuse,简称为FFR)方案降低小区间干扰强度。 In order to overcome inter-cell interference, fractional frequency reuse may be employed (Fractional FrequencyReuse, simply referred to as FFR) scheme to reduce inter-cell interference strength.

[0006] 图1是根据相关技术的相邻扇区的频率资源分配方式及各个子带的发射功率限制情况的示意图,如图1所示,为相邻扇区的频率资源分配方式及各个频率分区(Frequency Partition,简称为FP)的发射功率限制情况的示意图。 [0006] FIG. 1 is a schematic view of the case according to the transmission power limit frequency resource allocation adjacent sectors of the related art and each sub-band shown in Figure 1, the frequency resource allocation and the respective frequencies of the adjacent sectors partition (Frequency partition, referred to as FP) is a schematic diagram of transmit power limitation situation. FFR方案的主要原理为: The main principle of FFR scheme is as follows:

[0007] 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 = 4,即将可用频率资源划分为[??1,? [0007] First, the available frequency resources are divided into N number of the FP, N is an integer greater than zero, it is assumed N = 4, is about the available frequency resources are divided into [?? 1 ,? ?2,? ?2,? ?3,? ? 3 ,? ?4]。 ? 4]. 其中,? among them,? ? 1,? 1,? ?2,? ?2,? ?3的频率重用因子为3(即1^11863, 也称作Reusel/3),FP1,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采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频率重用因子为1 (即Reusel),三个相邻扇区都可以使用该频率资源。 ? 3 is the frequency reuse factor 3 (i.e., 1 ^ 11863, also referred to Reusel / 3), FP1, FP2, FP3 frequency resource allocation in three adjacent sectors to one sector, while the other two sectors the frequency resource can not be used or need transmit power limit of the subcarrier frequency resources ways to use the frequency resources; FP4 frequency reuse factor is 1 (i.e. Reusel), three neighboring sectors can use the frequency resources.

[0008] 然后,基站为每个FP分配一个资源度量值(Resource Metric,简称为RM),即[RM 1,RM 2, RM 3, RM 4],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,简称为SE),并且通过计算各个FP 的nSEi (nSEi = SEi/RMi, 其中i为FP的索引号)的大小,反馈nSEi最大的M(M大于等于1)个FP的信道质量信息(Channel Quality Information,简称为CQI)到基站,基站根据终端上报的FP的CQI情况进行资源分配,。 [0008] Then, each FP allocate a resource metric (Resource Metric, abbreviated as RM) to the base station, i.e., [RM 1, RM 2, RM 3, RM 4], and notifies the terminal the resource metric, each terminal by measuring the spectral efficiency of each of FP (spectral efficiency, referred to simply as SE), and by calculating each of FP nSEi (nSEi = SEi / RMi, where i is the FP index number) size, feedback nSEi maximum of M (M is greater than equal to 1) of the FP channel quality information (channel quality information, referred to as CQI) to the base station, resource allocation is performed based on the CQI reported by the terminal case of the FP.

[0009] 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,进而终端选择最优的频率分区。 [0009] Finally, the base station adaptively adjust the size of each of the FP, RM value of the transmission power of each subcarrier and each FP FP, and notifies all terminals in the local sector, and thus the terminal selecting an optimal frequency partitions.

[0010] 为了减少发送RM时的信令开销,产生了一种RM的量化方式,即基站发送的频率分区的量化后的资源度量值所采用的量化方式为:当RM大于等于O而且小于0. 5时,对RM的量化公式为Y = floor (RM/0. 125);当RM大于等于0.5而且小于0.8时,对RM的量化公式为Y = floor ((RM-0. 5) *8/0. 3)+4 ;当RM大于等于0.8而且小于等于1时,对RM的量化公式为Y = floor ((RM-0. 8)/0. 125)+12 ;其中,Y为RM对应的量化值。 [0010] In order to reduce signaling overhead of sending RM, RM way produces quantization, the quantization measure how resources are quantized frequency partition, i.e., a base station is used: When less than RM is greater than 0 and equal to O 5, the quantizing formulas RM is Y = floor (RM / 0 125.); when the RM is greater than or equal to 0.5 and less than 0.8, the quantization formulas RM is Y = floor ((RM-0 5) * 8. . / 03) + 4; and when the RM is greater than or equal to 0.8 or less to 1, the RM quantization formula for Y = floor ((RM-0 8.) / 0 125) +12;. wherein, Y is the corresponding RM quantized value. 经过上述公式可以将RM量化为4bit的信息,并且由基站发送给终端,但是终端接收到经过量化后的RM(即Y) 时,如何从Y恢复出RM却没描述,进而无法根据RM辅助终端进行频率分区的选择。 After the above formula RM may be quantized as 4bit information, and transmitted to the terminal by the base station, but the terminal passes RM (i.e., Y) after receiving the quantized, how to recover from the Y RM no description, and thus not in accordance with the auxiliary terminal RM the selected frequency partition.

[0011] 针对相关技术中存在的无法从量化后的资源度量值的恢复出资源度量值,进而无法根据RM辅助终端进行频率分区的选择的问题,目前尚未提出有效的解决方案。 [0011] For the problem can not, then not be able to select the frequency partition of the resources from the recovery measure resource metric quantized according to RM auxiliary terminal related art that has not yet come up with effective solutions.
