Description

一种分配空闲频谱的方法、装置及终端 Method, device and terminal for allocating idle spectrum

技术领域 Technical field

本发明涉及无线电频谱管理技术，尤指一种分配空闲频谱的方法、装置及终端。 The present invention relates to radio spectrum management techniques, and more particularly to a method, apparatus and terminal for allocating an idle spectrum.

背景技术 Background technique

在无线通信***中，无线频谱资源是一种必不可少的、并且极其有限的资源，随着宽带多媒体无线通信业务的持续发展，越来越多的无线业务出现之后，频谱资源更是紧缺。在传统的无线电频谱管理中，釆用单用途、固定分配方式将某频带划分给某无线业务，再将该频带分割成若干频段，分别授权给不同的无线业务运营商使用。在某频段上，授予某运营商的无线接入系统在全时段、整个地理区域内使用该频段的权利，即使该运营商的无线接入 ***不使用，其它***也无权使用该频段频率，这种拥有授权频谱的***称为 4受权***或主***或主用户。 In wireless communication systems, wireless spectrum resources are an indispensable and extremely limited resource. With the continuous development of broadband multimedia wireless communication services, more and more wireless services appear, and spectrum resources are in short supply. In the traditional radio spectrum management, a certain frequency band is allocated to a certain wireless service by a single-purpose and fixed allocation method, and then the frequency band is divided into several frequency bands and respectively granted to different wireless service operators for use. In a certain frequency band, the right of the wireless access system granted to an operator to use the frequency band in the whole time and in the entire geographical area, even if the wireless access system of the operator is not used, other systems do not have the right to use the frequency band. This system with licensed spectrum is called a 4-authorized system or a primary system or primary user.

认知***可以根据获取的授权***频谱占用情况信息，在不影响授权系统通信的前提下选择空闲频谱进行通信，这里的空闲频谱与时间和位置有关，指在该认知***设备所在位置某个时间段内主***不使用的频谱，认知无线电***也称为次级***或次级用户。釆用认知无线电***可以提高频谱的利用率，高效、灵活地使用在一定时间和空间区域内未被主***使用的频谱，当然，这一定要建立在授权频段处于空闲或授权频段只有很少的业务正在通信的情况下，才能达到极大地提高频谱资源利用率，解决日益增长的无线通信业务需求与日渐匮乏的频谱资源之间的矛盾的目的。 The cognitive system can select the idle spectrum to communicate according to the acquired spectrum occupancy information of the authorized system without affecting the communication of the authorized system. The idle spectrum here is related to the time and location, and refers to the location of the cognitive system device. The spectrum that the primary system does not use during the time period, the cognitive radio system is also called the secondary system or secondary user. The cognitive radio system can improve the spectrum utilization, and efficiently and flexibly use the spectrum that is not used by the main system in a certain time and space area. Of course, this must be established when the licensed frequency band is idle or the licensed frequency band is only very small. The business is communicating, in order to greatly improve the utilization of spectrum resources, and to resolve the contradiction between the growing demand for wireless communication services and the increasingly scarce spectrum resources.

在认知无线电中，当次级***的频谱资源不够用时，如负荷较重，次级 ***的基站会向频谱协调器或数据库请求空闲频谱，频谱协调器或数据库根据该基站所在位置的频谱空闲情况及其他基站的频语使用情况，为该基站协调分配空闲频谱。由于当次级***使用主***频谱资源进行通信时，不能对主用户造成干扰，这是认知无线电技术能够实现的前提条件，因此，需要限制次级***的使用频谱及发射参数。另外，由于可能存在多个次级用户同时使用相同或相邻的空闲频谱，因此，为了次级用户之间的共存，发射参数又会受到进一步的限制。这种情况下，很有可能造成次级***使用空闲频谱时不能满足其服务质量要求，目前，次级***的基站并不知道次级***使用主 ***空闲频谱进行通信时能否满足次级***服务质量的要求，而对于次级系统来说，如果空闲频谱不能满足其服务质量要求，而基站按照频谱协调器或数据库分配的空闲频谱配置到该空闲频谱进行通信时，将会导致其通信性能下降，从而对次级***的服务质量产生严重影响。 In cognitive radio, when the spectrum resources of the secondary system are not enough, such as heavy load, the base station of the secondary system requests the spectrum coordinator or database for the idle spectrum, and the spectrum coordinator or database is idle according to the spectrum of the location of the base station. The situation and the frequency usage of other base stations coordinate the allocation of idle spectrum for the base station. Since the secondary system cannot communicate with the primary user when it uses the primary system spectrum resources for communication, this is a prerequisite for cognitive radio technology to be implemented. Therefore, it is necessary to limit the usage spectrum and transmission parameters of the secondary system. In addition, because there may be multiple secondary users simultaneously The same or adjacent free spectrum is used, so the transmission parameters are further limited for coexistence between secondary users. In this case, it is very likely that the secondary system cannot meet its quality of service requirements when using the idle spectrum. Currently, the base station of the secondary system does not know whether the secondary system can satisfy the secondary system when communicating with the primary system idle spectrum. The quality of service requirements, and for the secondary system, if the idle spectrum cannot meet its quality of service requirements, and the base station communicates to the idle spectrum according to the spectrum coordinator or the allocated spectrum of the free spectrum allocated by the database, it will cause its communication performance. Declining, which has a serious impact on the quality of service of the secondary system.

Protocol )业务数据单元（ SDU, Service Delivery Unit )丟包数，总包数指的是 PDCP SDU总包数。 Protocol) The number of packets lost by the Service Data Unit (SDU). The total number of packets refers to the total number of PDCP SDUs.

由第三代合作伙伴计划（3GPP, 3^rd Generation Partnership Project )协议可知， PDCP、无线链路控制（ RLC, Radio Link Control )、介质访问控制（ MAC, Media Access Control )子层间数据包的对应关系如图 2所示，根据 RLC SDU 和 RLC PDU之间的对应关系以及 MAC SDU和 MAC PDU之间的对应关系就可以获得 PDCP SDU和 TB的对应关系。 Protocol understood by the Third Generation Partnership Project ^{(3GPP, 3 rd Generation Partnership Project} ), correspondence between PDCP, a radio link control (RLC, Radio Link Control), medium access control (MAC, Media Access Control) sublayer of the data packet As shown in FIG. 2, the correspondence between the PDCP SDU and the TB can be obtained according to the correspondence between the RLC SDU and the RLC PDU and the correspondence between the MAC SDU and the MAC PDU.

为了方便计算丟包数和总包数，作如下假设：（ 1 ) TB中 RLC PDU占 TB的 90%, 其余的 10%为 MAC头、 MAC CE、 Padding等；（ 2 )—个 TB 只包含一个 RLC PDU; ( 3 )不考虑对 RLC SDU拆包的情况，只考虑对 RLC SDU组包的情况。在假设的前提下， RLCSDU与 TB的对应关系，和 PDCP SDU与 TB的对应关系一致。 To facilitate the calculation of the number of lost packets and the total number of packets, the following assumptions are made: (1) RLC PDUs in TB 90% of TB, the remaining 10% are MAC header, MAC CE, Padding, etc.; (2) - TB contains only one RLC PDU; (3) Regardless of the case of unpacking RLC SDU, only consider the RLC SDU group The case of the package. On the premise of the assumption, the correspondence between the RLCSDU and the TB is the same as the correspondence between the PDCP SDU and the TB.

假设在单位时间内有 n个 RLC SDU数据包，大小依次为 L_l L₂, ... , Suppose there are n RLC SDU packets in unit time, and the size is L _l L ₂ , ... ,

V" τ V" τ

L_n, 则单位时间内的 RLC SDU数据包的平均大小为 J = ^^ 。 L _n , then the average size of the RLC SDU packets per unit time is J = ^^ .

n n

RLC PDU数据包的大小可以设置为 RLC SDU数据包大小的整数倍，且不超过 TB大小的 90%; 则一个 RLC PDU数据包包含的 RLC SDU数据包的个数为 =^^1 (舍去小数部分），其中， L_TB为 TB的大小（字节）。例如，假设 L=4000个字节， TB的大小为 75376比特（即 9422字节）, RLC PDU 数据包的大小小于等于 9422*90%=8479.8字节，则一个 RLC PDU数据包最多包含的 RLC SDU数据包的个数为 8479.8/4000=2.12个，也就是说一个 RLC PDU数据包包含 2个 RLC SDU数据包，即一个 TB包含 2个 RLC SDU数据包。 The size of the RLC PDU packet can be set to an integer multiple of the RLC SDU packet size and does not exceed 90% of the TB size; then the number of RLC SDU packets contained in one RLC PDU packet is =^^1 (rounded down) The fractional part), where L _TB is the size of the TB (bytes). For example, suppose L=4000 bytes, the size of the TB is 75376 bits (that is, 9422 bytes), and the size of the RLC PDU packet is less than or equal to 9422*90%=8479.8 bytes, then the RLC of a RLC PDU packet is at most The number of SDU data packets is 8479.8/4000=2.12, that is, one RLC PDU data packet contains two RLC SDU data packets, that is, one TB contains two RLC SDU data packets.

单位时间内， PDCP SDU丟包数为： KNBLER^m+ PDCP SDU总包数为：The number of PDCP SDU packet loss per unit time is: KNBLER ^m+ PDCP SDU total packet number is:

Throughput requirements; otherwise not met. When the communication performance is the transmission rate, the base station compares the transmission rate and the transmission rate threshold. When the transmission rate is greater than or equal to the transmission rate threshold, the base station determines that the transmission rate when using the idle frequency band for communication meets the minimum transmission rate requirement of the base station. Otherwise it is not satisfied.

当通信性能为丟包率时，基站比较丟包率与丟包率门限的大小；当丟包率小于或等于丟包率门限时，基站判断出使用空闲频段进行通信时的丟包率满足基站的最大丟包率要求，否则不满足。 When the communication performance is the packet loss rate, the base station compares the packet loss rate and the packet loss rate threshold. When the packet loss rate is less than or equal to the packet loss rate threshold, the base station determines the packet loss rate when the idle frequency band is used for communication. The maximum packet loss rate requirement of the base station is met, otherwise it is not satisfied.

当通信性能为吞吐量、传输速率和丟包率中的两个或三个时，应同时满足所有通信性能参量的要求。 When the communication performance is two or three of throughput, transmission rate, and packet loss rate, all communication performance parameters should be met at the same time.

其中，吞吐量门限、传输速率门限或丟包率门限可以预先设置，也可以根据基站的服务质量要求进行调整。本步骤中，如果有多个空闲频段满足通信性能要求，则基站从多个空闲频段中选择一个通信性能较好的空闲频段，或随机选择一个空闲频段，然后配置到该空闲频段上，即使用该空闲频段进行通信；如果所有空闲频段都不满足通信性能要求，则基站重新发起资源配置请求或放弃本次资源配置。 The throughput threshold, the transmission rate threshold, or the packet loss threshold may be preset or may be adjusted according to the quality of service requirements of the base station. In this step, if multiple idle frequency bands meet the communication performance requirements, the base station selects one idle frequency band with better communication performance from multiple idle frequency bands, or randomly selects one idle frequency band, and then configures to the idle frequency band, that is, uses The idle frequency band performs communication; if all the idle frequency bands do not meet the communication performance requirement, the base station re-initiates the resource configuration request or discards the current resource configuration.

本发明根据获得的 SINR计算通信性能，并判断通信性能是否满足服务质量要求，从而对空闲频谱的服务质量进行了预估计，而且仅在通信性能满足次级***的服务质量要求时，基站才使用当前获得的空闲频段进行通信，提高了次级***的通信性能。 The present invention calculates communication performance based on the obtained SINR, and determines whether the communication performance satisfies the quality of service requirement, thereby pre-estimating the quality of service of the idle spectrum, and only when the communication performance meets the quality of service requirements of the secondary system, the base station uses The currently obtained idle frequency band is communicated, improving the communication performance of the secondary system.
