Description

控制终端能力的方法、 终端、 基站和计算机存储介质 技术领域
本发明涉及移动通信中的终端能力管理技术， 尤其涉及一种控制终端 能力的方法、 终端、 基站和计算机存储介质。 背景技术
在长期演进 ( Long term Evolution, LTE ) 系统中， 用户终端 （User Equipment, UE )能力包括： UE的最大发射功率、 UE在一个传输时间间隔 内所能接收和发送的最大数据量、 UE内存中能够緩存的最大数据量等。 对 于 UE的最大发射功率， 在通信时， 要求当前的发射功率不能超过 UE的最 大发射功率。 通常， UE通过功率余量报告 ( Power Headroom Report, PHR ) 将 UE 的最大发射功率与当前上行共享信道的发射功率之差通知基站 ( evolved Node B, eNB ) , eNB根据 UE发送的通知进行上行调度、 链路 适配、 以及决定是否进行功率控制， 如： 通过减小或增加发射功率、 调整 发射功率的大小，来满足 UE当前的发射功率不能超过 UE的最大发射功率 的要求。
上述 UE能力在单载波的情况下， 可以得到 4艮好的控制。 但是， 由于频 谱资源的匮乏以及移动用户业务的激增， 采用高频点进行热点覆盖的需求 日益明显； 因此， 为增加用户的吞吐量和移动性能， 采用低功率的节点成 为新的应用场景。 由于采用高频点进行热点覆盖时， 存在移动信号衰减严 重、 小区的覆盖范围小、 与现有的小区不能共用站点等缺点； 于是， 运营 商采用双连接作为增强方案。
在双连接下， UE可以同时与两个以上的网络节点保持连接， 但是， 在 控制面， UE只与其中一个小区连接； 这里， 网络节点是指 eNB, 且 eNB 之间的时延不可以忽略； 如： 宏基站作为网络节点称为 MeNB , 小小区基 站作为网络节点成为 SeNB, 两个网络节点对 UE实时调度， 一个网络节点 并不能及时获知另一个网络节点对 UE的调度情况； 因此，在某个时刻或某 些时刻， 会由于 UE超出自身能力而导致数据发送失败、 数据丟失等问题， 降低用户体验。 发明内容

具体的， UE向第一 eNB和第二 eNB上报第一 eNB和第二 eNB的 BSR, 通知 UE在第一 eNB上需要发送的数据是 1000, UE在第二 eNB上需要发 送的数据是 2000,即： UE在第一 eNB和第二 eNB上发送数据的比例是 1:2。
步骤 403 ,第一 eNB和第二 eNB根据收到的 BSR以及依据 UE能力范 围协商的 UE能力分配规则， 为各个 UE配置上行授权；
第一 eNB获知 UE在第一 eNB和第二 eNB发送的数据比例为 1: 2, 即 UE用三分之一的功率发送第一 eNB的数据， UE用三分之二的功率发送 第二 eNB的数据， 第一 eNB和第二 eNB以此为 UE配置上行授权。
在步骤 403之后， 在小区的信号质量发生变化、 或小区的负荷发生变 化、 或某一 eNB的数据量突增的情况下， eNB可以提出重新协商 UE能力 分配规则； UE用于发送第一 eNB数据的能力与 UE用于发送第二 eNB数 据的能力分配比例并不完全等同于 UE在第一 eNB上的緩沖区数据与 UE 在第二 eNB上的緩沖区数据比例。
以第一 eNB是 MeNB, MeNB下有第一小区，第二 eNB是 SeNB, SeNB 下有第三小区和第四小区为例， MeNB和 SeNB均只有一个 LCGO, UE与 第一小区建立连接， 随着业务量增加， MeNB根据测量报告， 给 UE增加第 三小区， 并配置第一数据无线承载和第二数据无线承载， 两个数据无线承 载均归属于 LCG0; 其中， 第一数据无线承载是 MeNB上的承载， 第二数 据无线承载是 SeNB上的承载；相应的，本实施例中一种控制终端能力的方 法的详细实现流程如图 5所示， 包括以下步骤：
步骤 501 , MeNB和 SeNB依据 UE能力范围协商 UE能力分配规则； 具体的， MeNB和 SeNB根据两个基站的緩沖区数据大小比例和 UE能 力范围， 分配 UE在 MeNB和 SeNB可以使用的能力。
步骤 502, UE向 MeNB和 SeNB上报内容相同的 BSR; 具体的， 预先约定先上报 MeNB的 BSR, 再上报 SeNB的 BSR;
上报的 BSR内容如图 6所示， BSR中包含 LCG0上的緩沖数据信息； 由于 MeNB和 SeNB均只有一个 LCG0 , 因此， 上报短 BSR。
步骤 503 , MeNB和 SeNB根据收到的 BSR以及依据 UE能力范围协商 的 UE能力分配规则 , 为各 UE配置上行授权；
具体的， MeNB和 SeNB可以根据收到的 BSR以及步骤 501中协商的 UE能力分配规则 , 为 UE配置上行授权； MeNB和 SeNB也可以根据收到 的 BSR, 决定再次协商 UE能力分配规则； 协商完成后， MeNB和 SeNB按 照新的 UE能力分配规则为 UE配置上行授权。
以第一基站是 MeNB , MeNB下有第一小区， 第二基站是 SeNB , SeNB 下有第三小区和第四小区为例， MeNB和 SeNB均只有一个 LCGO, UE与 第一小区建立连接， 随着业务量增加， MeNB根据测量报告， 给 UE增加第 三小区， 并配置第一数据无线承载和第二数据无线承载， 两个数据无线承 载均归属于 LCG0; 其中， 第一数据无线承载是 MeNB的承载， 第二数据 无线承载是 SeNB上的承载， 第二无线承载可以通过 MeNB和 SeNB分别 发送； 相应的， 本实施例中另一种控制终端能力的方法的详细实现流程如 图 7所示， 包括以下步骤：
步骤 601 , MeNB和 SeNB依据 UE能力范围协商 UE能力分配规则； 具体的， MeNB和 SeNB根据两个基站的緩沖区数据大小比例和 UE能 力范围， 分配 UE在 MeNB和 SeNB可以使用的能力。
步骤 602, UE向 MeNB和 SeNB上艮内容不同的 BSR;
具体的， UE按约定向 MeNB先上报 MeNB的 BSR, 再上报 SeNB的 BSR; 或 UE按约定向 SeNB先上报 SeNB的 BSR, 再上报 MeNB的 BSR。
UE向 MeNB上报的 BSR内容如图 8所示， UE向 SeNB上报的 BSR 内容如图 9所示， BSR中包含 LCG0上的緩沖数据信息；由于 MeNB和 SeNB 均只有一个 LCGO, 因此， 上报短 BSR。
步骤 603 , MeNB和 SeNB根据收到的 BSR以及依据 UE能力范围协商 的 UE能力分配规则 , 为各 UE配置上行授权；
具体的， MeNB和 SeNB可以根据收到的 BSR以及步骤 601中协商的 UE能力分配规则 , 为 UE配置上行授权； MeNB和 SeNB也可以根据收到 的 BSR, 决定再次协商 UE能力分配规则； 协商完成后， MeNB和 SeNB按 照新的 UE能力分配规则为 UE配置上行授权。
以第一基站是 MeNB , MeNB下有第一小区， 第二基站是 SeNB , SeNB 下有第三小区和第四小区为例， MeNB有两个 LCG,分别为 LCG0和 LCG1 , SeNB有一个 LCG, UE与第一小区建立连接， 随着业务量增加， MeNB根 据测量报告，给 UE增加第三小区，并配置第一数据无线承载和第二数据无 线承载； 其中， 第一数据无线承载： 第一数据无线承载归属 LCG0, 第二数 据无线承载归属 LCG1 ; 其中， 第二数据无线承载可以通过 MeNB和 SeNB 分别发送。 相应的， 本实施例中又一种控制终端能力的方法的详细实现流 程如图 10所示， 包括以下步骤：
步骤 701 , MeNB与 SeNB依据 UE能力范围协商 UE能力分配规则； 具体的， MeNB与 SeNB根据两个基站的緩沖区数据大小比例和 UE能 力范围， 分配 UE在 MeNB和 SeNB可以使用的能力。
步骤 702, UE向 MeNB上报长 BSR, 向 SeNB上报短 BSR;
具体的， 由于 MeNB有两个 LCG, 因此， 上报长 BSR; 长 BSR中包 含 LCG0和 LCG1上緩沖区数据信息；
由于 SeNB有一个 LCG, 因此， 上报短 BSR; 短 BSR中包含 LCG0上 緩沖区数据信息；
如图 11所示， 在上艮的 BSR前增加基站标识信息； 其中， MeNB标识 和 SeNB标识可以是包含 28比特的全局标识， 也可以是相对标识； 其中， 基站 ID小的基站用 0表示， 基站 ID大的基站用 1表示； 或基站 ID小的基 站用 1表示， 基站 ID大的基站用 0表示.
本步骤中， 若存在多个基站， 可以按照实际基站标识发送 BSR, 也可 以按照基站 ID从大到小或从小到大的顺序发送 BSR。
步骤 703 , MeNB和 SeNB根据收到的 BSR以及依据 UE能力范围协商 的 UE能力分配规则 , 为各 UE配置上行授权。
本实施例中， 若基站还为终端配置 LCG2和 LCG3上的数据无线承载， 那么终端需按照步骤 702所述技术方案对所有 LCG进行上报。
