一种载波级小区选择的方法与装置Method and device for carrier-level cell selection

技术领域technical field

本发明涉及无线通信技术领域，具体涉及一种载波级小区选择的方法与装置。The present invention relates to the technical field of wireless communication, in particular to a method and device for carrier-level cell selection.

背景技术Background technique

移动通信系统已经发展到第三代，为了进一步提高系统的频谱效率和用户吞吐量，LTE引入载波聚合技术。载波聚合是指UE可以同时使用多个成员载波，一个成员载波是LTE的UE可以接入的载波段，其载波带宽从1.25M至20M，每个载波具有一个同步信道，一个广播信道等，每个成员载波可以视为一个小区，可以支持用户终端接入，而且这些多个成员载波可以位于同一个接入网节点下，这样就使得在同一个接入网节点下的小区数目急剧增加，例如，LTE R10要求最大100M的带宽，而LTE R8系统带宽最大是20M，至少需要5个成员载波聚合，相比同一个接入网节点下的单载波而言，小区的数目增大了5倍。The mobile communication system has been developed to the third generation. In order to further improve the spectrum efficiency and user throughput of the system, LTE introduces carrier aggregation technology. Carrier aggregation means that a UE can use multiple component carriers at the same time. A component carrier is a carrier segment that an LTE UE can access. Its carrier bandwidth ranges from 1.25M to 20M. Each carrier has a synchronization channel and a broadcast channel. A component carrier can be regarded as a cell, which can support user terminal access, and these multiple component carriers can be located under the same access network node, so that the number of cells under the same access network node increases sharply, for example , LTE R10 requires a maximum bandwidth of 100M, while the maximum bandwidth of LTE R8 system is 20M, requiring at least 5 component carrier aggregations. Compared with the single carrier under the same access network node, the number of cells has increased by 5 times.

负载均衡主要是处理多个异频和异系统的业务负载分配不均匀问题。负载均衡算法可以通过切换或者载波级小区重选判决把业务从高负载的小区转移到低负载的小区。Load balancing is mainly to deal with the problem of uneven business load distribution of multiple different frequencies and different systems. The load balancing algorithm can transfer services from high-loaded cells to low-loaded cells through handover or carrier-level cell reselection decisions.

引入载波聚合后，如果一个小区有多个可以驻留的载波，每个成员载波都有自己独立的同步信道SCH/广播信道BCH，LTE/LTE-A的UE可能驻留在任何一个可以驻留的载波上，造成大量的UE驻留在同一个载波上，通过广播消息获得驻留载波的物理随机接入信道PRACH资源，如果大量UE驻留在同一个下行载波上，UE会在对应的上行载波上传输随机接入信道前导RACHpreamble，这会导致PRACH资源的冲突和性能恶化。After carrier aggregation is introduced, if a cell has multiple carriers that can camp on, and each component carrier has its own independent synchronization channel SCH/broadcast channel BCH, LTE/LTE-A UEs may camp on any one that can camp on. A large number of UEs camp on the same carrier, and obtain the physical random access channel PRACH resources of the camped carrier through broadcast messages. If a large number of UEs camp on the same downlink carrier, the UE will The random access channel preamble RACH preamble is transmitted on the carrier, which will cause collision of PRACH resources and performance degradation.

具体实施方式Detailed ways

为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

当UE选择一个公众陆地移动电话网PLMN后，UE开始寻找合适的小区驻留，称做“小区选择”，驻留小区的条件要求符合小区选择S准则，即Srxlev＞0，具体为：When the UE selects a public land mobile telephone network PLMN, the UE starts to look for a suitable cell to reside in, which is called "cell selection". The conditions for camping in a cell must meet the cell selection S criteria, that is, Srxlev>0, specifically:

Srxlev＝Q_rxlevmeas-(Q_rxlev min+Q_{rxlev min offest})-PcompensationSrxlev＝Q_rxlevmeas -(Q_{rxlev min} +Q_{rxlev min offest} )-Pcompensation

 SrxlevSrxlev  小区选择的接收电平值(dB)The receiving level value of cell selection (dB) Q_rxlevmeasQ_rxlevmeas  测量的当前服务小区的接收电平值(RSRP).The measured reception level value (RSRP) of the current serving cell. Q_rxlev minQ_{rxlev min}  接收电平门限值(dBm)Receive level threshold (dBm) Q_{rxlev min offest}Q_{rxlev min offest}  接收电平门限值的偏置值The offset value of the receive level threshold PcompensationCompensation  补偿值max(P_EMAX-P_UMAX，0)(dB)Compensation value max(P_EMAX -P_UMAX , 0)(dB) P_EMAXP_EMAX  UE可以使用的最大发射功率The maximum transmit power that UE can use P_UMAXP_UMAX  按照UE功率级别确定的最大射频输出功率The maximum RF output power determined according to the UE power level

其中，Q_{rxlev min offset}是指当UE驻留在访问公众陆地移动电话网VPLMN的情况下，通过给接收电平门限增加一个差值，从而让UE可以周期性地搜索更高优先级的公众陆地移动电话网PLMN，其主要目的是防止PLMN之间的乒乓选择。Among them, Q_{rxlev min offset} means that when the UE resides in and accesses the public land mobile telephone network VPLMN, by adding a difference to the receiving level threshold, the UE can periodically search for a higher priority public land mobile network The main purpose of the mobile phone network PLMN is to prevent ping-pong between PLMNs.

UE驻留在一个合适小区，开始执行小区重选过程，使UE驻留到一个更好的小区上。The UE camps on a suitable cell, and starts to perform the cell reselection process, so that the UE camps on a better cell.

对于异频和异系统的小区重选主要是依据频率的绝对优先级；For inter-frequency and inter-system cell reselection, it is mainly based on the absolute priority of frequency;

对于满足S准则的同频和同优先级的异频小区采用R准则进行排序，该R准则如下所示：For the inter-frequency cells of the same frequency and the same priority that meet the S criterion, the R criterion is used for sorting, and the R criterion is as follows:

R_s＝Q_meas，s+Q_HystR_s = Q_{meas, s} + Q_Hyst

R_n＝Q_meas，n-Q_offsetR_n = Q_{meas, n} - Q_offset

 Q_measQ_meas  小区的接收电平值(RSRP)The receiving level value of the cell (RSRP) Q_offestQ_offest  小区的偏置值The offset value of the cell

其中R_s服务载波的排序准则，R_n目标载波的排序准则，如果R_n在UE的小区重选评估时间内大于R_s，则认为UE可以选择到更好的候选小区上。其中，对于同频场景，若R_n在UE的小区重选评估时间内小于R_s，则Q_offset可以等于服务小区和邻小区的偏置值Q_offsets，n；R_n在UE的小区重选评估时间内大于R_s，则Q_offset可以等于0。对于异频场景，R_n在UE的小区重选评估时间内大于R_s，则该Q_offset t等于Q_offsets，n+Q_{offsetfrequency}；否则Q_offset等于Q_{offsetfrequency}。换句话说，Q_offset等于服务和邻小区的偏置值加上频率的偏置值。Among them, R_s is the ranking criterion of the serving carrier, and R_n is the ranking criterion of the target carrier. If R_n is greater than R_s within the cell reselection evaluation time of the UE, it is considered that the UE can select a better candidate cell. Among them, for the same-frequency scenario, if R_n is less than R_s within the cell reselection evaluation time of the UE, then Q_offset can be equal to the offset value Q_{offsets, n} of the serving cell_and the neighboring cell; If the evaluation time is greater than R_s , then Q_offset can be equal to 0. For the inter-frequency scenario, if R_n is greater than R_s within the cell reselection evaluation time of the UE, then the Q_{offset t} is equal to Q_offsets,n +Q_{offsetfrequency} ; otherwise, Q_offset is equal to Q_{offsetfrequency} . In other words, Q_offset is equal to the offset value of the serving and neighboring cells plus the offset value of the frequency.

由于目前的小区驻留和小区重选的参数都是通过系统信息广播的小区级参数，对于小区内全部UE可以接收该参数，对于载波聚合场景，如果一个小区有多个可以驻留的载波，每个成员载波都有独立的SCH/BCH，LTE/LTE-A的UE可能驻留在任何一个可以驻留的载波上，造成大量的UE驻留在同一个载波上，通过广播消息获得驻留载波的PRACH资源，如果大量UE驻留在同一个下行载波上，UE会在对应的上行载波上传输RACH前导，这会导致PRACH资源的冲突和性能恶化。Since the current cell camping and cell reselection parameters are all cell-level parameters broadcasted through system information, all UEs in the cell can receive this parameter. For the carrier aggregation scenario, if a cell has multiple carriers that can camp on, Each component carrier has an independent SCH/BCH, and LTE/LTE-A UEs may camp on any carrier that can camp on, resulting in a large number of UEs camping on the same carrier, and obtain camping through broadcast messages PRACH resources of the carrier, if a large number of UEs reside on the same downlink carrier, the UE will transmit RACH preamble on the corresponding uplink carrier, which will cause PRACH resource conflict and performance degradation.
