Description

上行资源分配、 状态报告发送方法及装置 技术领域
本发明涉及无线通信技术领域， 尤其涉及上行资源分配、 状态报告发送 方法及装置。 背景技术
现有移动通信系统的上行调度过程主要包含两方面内容， 一是緩存状态 报告 BSR ( Buffer Status Report )机制， 二是上行资源分配过程。
现有 3GPP LTE R8的规范 3GPP TS 36.321 V8.3.0中定义了移动终端 UE ( User Equipment )发送给基站的 BSR报告的格式和内容。 其中， 具有 QoS
Group )进行 BSR报告，其中短 BSR只报告具有最高优先级 RBG的緩存数据 量 BS( Buffer Size )，其格式如图 1所示，而长 BSR可以报告四种 RBG的 BS， 其格式如图 2所示， 其中 LCG ID为逻辑信道组的标识号， Buffer Size为每个 RBG的緩存数据量， Oct表示一个字节。
对于上行资源分配过程（也可以称作上行速率控制过程）， 3GPP TS 36.321 V8.3.0和 3GPP TS 36.300 V8.6.0中还定义了当前 LTE规范中的上行资源分配 过程， UE侧的资源分配过程主要通过令牌桶机制来完成， 如图 3所示：
每个 RB对应一个令牌桶， 其中 BS为该 RB对应的緩存数据量， 优先级 比特速率 PBR ( Prioritized Bit Rate )为对应令牌桶每个周期内实际注入的速 率， 即每个周期内放入令牌桶中的令牌数， PBR可以理解为 RB的基本速率 要求或者基本保证速率要求， 该值是与 RB优先级相关的固定数值， Bj为令 牌桶中令牌数， R为当前发送周期实际发送的数据量。
UE侧通过令牌桶机制进行上行资源分配和上行速率控制方法如下： 步骤 1： 在上行数据发送周期到达时根据 PBR更新 Bj。
步骤 2: 按 RB优先级从高到底的顺序为所有 Bj>0的 RB分配资源， 并 根据资源分配结果更新 Bj ( Bj可以为负， 这样可以避免数据包的频繁分割和 組装 )；
步骤 3: 如果仍有上行资源剩余， 则按照优先级从高到低的顺序为每个 RB分配资源 （不管 Bj值的大小）， 直到该 RB的緩存数据发送完毕或者没有 剩余上行资源 （该步骤中 Bj不再更新）。
上述步骤 2中进行第一次上行资源分配， 通过对 Bj>0的 RB按照其对应 的 Bj、 对应的 BS和当前剩余上行资源的最小值分配上行资源， 以达到优先 满足优先级高的 RB的 PBR速率要求的目的。
上述步骤 3 中进行第二次上行资源分配， 将第一次上行资源分配后的剩 余上行资源分配给各 RB, 以达到充分利用上行资源的目的。
基站根据各 UE上报的 BSR为各 UE进行上行资源分配的理想情况应为， 使得 UE采用上述令牌桶机制分配上行资源给其各 RB时， UE获得的上行资 源足够完成上述步骤 1中的上行资源分配， 即满足其各 RB对应的 PBR速率 要求。 但由于上行资源有限， 基站可能无法合理分配上行资源给各 UE， 即可 能存在有的 UE获得的上行资源可以满足其各 RB对应的 PBR速率要求后， 上行资源还有剩余，而此时有的 UE获得的上行资源还无法满足其各 RB对应 的 PBR速率要求。 例如， 当一个 UE进行上行资源分配时， 满足其各 RB对 应的 PBR速率要求， 且将剩余上行资源分配给其各 RB后， 该 UE的 RBG的 緩存数据量仍然艮大时， UE将该緩存数据量上报基站后， 基站根据该緩存数 据量仍会分配较多上行资源给该 UE, 由于上行资源有限， 导致基站分配给其 他 UE的上行资源不足以满足其他 UE各 RB的 PBR速率要求，造成基站给各 UE分配上行资源不合理。
UE按上述令牌桶机制对其各 RB进行上行资源分配， 在执行第一次上行 资源分配， 满足各 RB对应的 PBR速率要求后， 如还有上行资源剩余， 则执 行第二次上行资源分配， 即按优先级从高到低的顺序将剩余上行资源分配给 各 RB, 假定某一个 RB获得了剩余上行资源， 但此时不再更新该 RB对应的 Bj, 如果在下一个发送周期内， UE获得的上行资源不足以满足所有 RB对应 的 PBR速率要求时， 但 UE仍可能将优先分配上行资源给该 RB, 因此， 导致 在满足该 RB对应的 PBR速率要求后， 该 RB获得了更多的上行资源同时， 还存在没有满足 PBR速率要求的 RB， 造成上行资源分配不合理。 发明内容

更新单元， 用于在上行数据发送周期到达时， 更新各无线承载对应的令 牌桶中的令牌数；
第一分配更新单元， 用于按所述各无线承栽优先级从高到低的顺序， 对 令牌数大于零的第一无线承栽进行第一次上行资源分配， 并根据第一次分配 的上行资源更新所述第一无线承栽对应的令牌桶中的令牌数；
第二分配更新单元， 用于当存在剩余的上行资源时， 确定出第二无线承 栽进行第二次上行资源分配， 并根据第二次分配的上行资源更新所述第二无 线承栽对应的令牌桶中的令牌数。

计算单元， 用于对各无线承载组， 计算出包含的各无线承载对应的所述 较小值的和值；
发送单元， 用于发送所述和值给基站； 或者当满足设置条件时发送所述 和值给基站。 本发明实施例提供了一种上行资源分配方法， 用于移动终端分配上行资 源给其各无线承载， 该方法中在第一次和第二次分配上行资源给无线承载时， 均根据分配的上行资源更新无线承载对应令牌桶中的令牌数， 因此， 该令牌 数可以更准确表示其对应的长期统计的 PBR速率的满足情况， 例如， 在第二 次上行资源分配中获得上行资源的无线承栽， 其对应的令牌数在更新后为负 值， 该负值越小， 在下一个上行数据发送周期开始时， 才艮据该无线承栽对应 的 PBR更新后的其对应的令牌数越小， 相应的， 在下一个上行数据发送周期 第一次上行资源分配中， 该无线承栽获得的上行资源越少， 如果更新后的令 牌数仍为负值， 则在第一次上行资源分配中不分配上行资源给该无线承载， 因此， 可以减少对已满足 PBR速率要求的无线承载分配的上行资源， 进而避 免出现满足 PBR速率要求的无线承栽获得更多上行资源的同时， 还存在没有 满足 PBR速率要求的无线承载的情况， 达到 UE更合理的分配上行资源给其 各无线承载的目的。
本发明实施例还提供了一种状态报告发送方法， 移动终端确定出当前上 行数据发送周期内在第二次上行资源分配中获得上行资源或获得的上行资源 数量大于设定阈值的第一无线承栽； 以及对各无线承载组， 计算出除第一无 线承栽外的其余各无线承栽对应的緩存数据量的和值； 并发送该和值给基站。 上述第一无线承栽获得满足其 PBR速率要求的上行资源后再次获得了上行资 源， 表示该 UE获得了满足其各无线承栽对应的 PBR速率要求外更多的上行 资源， 当出现该情况时， 与发送组成该无线承栽组的所有无线承载的緩存数 据量的和值给基站相比， 该方法发送的和值更小， 因此， 相应的， 基站根据 接收的该和值分配给该 UE的上行资源较少，进而可以将减少的上行资源分配 给其他 UE，避免出现已满足各 RB对应的 PBR速率要求的 UE获得更多上行 资源的同时， 还存在没有满足各 RB对应的 PBR速率要求的 UE的情况， 达 到基站更合理的分配上行资源给各 UE的目的。

RB1 0 150 - 170 当前周期第
RB2 20 150 - 50 0 二次分配后

RB1 180 150 - 20 下一周期第
RB2 20 150 0 50 一次分配后
RB3 30 100 0 比较上述表 1和表 2中的数据可见： 采用现有上行资源分配方法， 当前 周期第二次分配后，在第二次分配中获得上行资源的 RB1和 RB2对应的令牌 数没有更新，所以在下一周期第一次分配前 RB1和 RB2对应的令牌数分别更 新为 150和 150， 进而在下一周期第一次分配中 RB1和 RB2分别获得 150字 节和 100字节的上行资源后，剩余上行资源为零，即在已满足 RB1对应的 PBR 速率要求后又分配给其更多的上行资源， 而 RB3获得的上行资源还没有满足 其对应的 PBR速率要求；而采用上述实施例一和实施例二提供的方法和装置， 当前周期第二次分配后，在第二次分配中获得上行资源的 RB1和 RB2对应的 令牌数分别更新为 - 170和- 50, 所以在下一周期第一次分配前 RB1和 RB2 对应的令牌数分别更新为- 20和 100， 进而在， 下一周期第一次分配中不分 配上行资源给 RB1 , 分配 100字节的上行资源给 RB2, 因此还可以分配 100 字节的上行资源给 RB3, 满足了 RB3对应的 PBR速率要求。 因此， 采用本发 明实施例一和实施例二提供的上行资源分配方法和装置， 使得移动终端更合 理的分配上行资源给其各无线承载。 实施例三：
本发明实施例三提供一种状态报告发送方法， 如图 8所示， 包括： 步骤 S801、 移动终端确定出当前上行数据发送周期内在第二次上行资源 分配中获得上行资源或获得的上行资源数量大于设定阈值的第一无线承栽。
步骤 S802、 对各无线承载组， 计算出除第一无线承载外的其余各无线承 载对应的緩存数据量的和值。
步骤 S803、发送该和值给基站； 或者满足设置条件时发送该和值给基站。 下面对本发明实施例三提供的状态报告发送方法进行详细阐述。
本发明实施例三中， UE側通过令牌桶机制， 将其获得的上行资源分配给 其包含的各 RB， 包括：
步骤 1: 在上行数据发送周期到达时根据优先级比特速率 PBR更新令牌 数 Bj。
步骤 2: 按照 RB优先级从高到低的顺序为所有 Bj>0的 RB分配资源， 并根据资源分配结果更新 Bj ( Bj可以为负， 这样可以避免数据包的频繁分割 和组装）。
步骤 3: 如果仍有上行资源剩余， 则按照优先级从高到低的顺序为每个 RB分配资源 （不管 Bj值的大小）， 直到该 RB的緩存数据发送完毕或者没有 剩余上行资源。
上述步骤 1中， 对每个 RB在其对应的原 Bj上加上其对应的 PBR数量， 结杲作为更新后其对应的 Bj。
上述步骤 2中进行第一次上行资源分配， 对于当前待处理的 RB, UE根 据该 RB对应的緩存数据量 BS、 该 RB对应的 Bj和剩余上行资源数量， 确定 分配给该 RB的上行资源。 当分配上行资源给该 RB后， 相应的更新该 RB对 应的 Bj， 具体为： 在原 Bj中减去分配给该 RB的上行资源数量， 结果作为更 新后的 Bj; 相应的还更新该 RB对应的 BS, 具体为： 在原 BS中减去分配给 该 RB的上行资源数量， 结果作为更新后的 BS; 相应的还更新剩余上行资源 数量， 具体为： 在原剩余资源数量中减去分给该 RB的上行资源数量， 结果作 为更新后的剩余上行资源数量。 完成该步骤后， 如不存在避免数据包分割和 组装的情况， Bj等于零， 如存在， 则 Bj小于零。
上述步骤 3为完成步骤 2后， 如果仍有上行资源剩余时执行的步驟。 步 驟 3中进行第二次上行资源分配， 即再次分配上行资源给若干个 RB, 对于再 次获得上行资源的 RB, 相应的更新该 RB对应的 BS, 具体为 , 在原 BS中减 去分配给该 RB的上行资源数量， 结果作为更新后的 BS; 相应的还更新剩余 上行资源数量，具体为：在原剩余资源数量中减去分给该 RB的上行资源数量， 结果作为更新后的剩余上行资源数量。 但对于各 RB对应的 Bj， 执行步骤 3 时， 各 RB对应的 Bj均小于等于零， 则即使 RB又获得上行资源， 也不更新 Bj。
因此， 上述步骤 S801中， 第一无线承载即为： 上述步骤 3中获得上行资 源的 RB或获得的上行资源大于设定阈值的 RB。
步骤 S802中计算各 RBG对应的緩存数据量时， 不考虑第一无线承载对 应的緩存数据量，即只计算出除第一无线承载外的其余各 RB的緩存数据量的 和值。
上述步骤 S803具体可以为：
每个上行数据发送周期都发送该和值给基站； 或者
满足设置条件时发送该和值给基站。 例如， 当该 RBG对应的该和值大于 设定阈值时发送该和值给基站； 或者周期地发送该 RBG的该和值给基站， 该 周期为上述上行数据发送周期的整数倍。
较佳地， 该 RBG的该和值可以通过移动终端发送给基站的媒体接入控制 层协议数据单元 MAC PDU中与 RBG对应的 MAC控制单元 MAC Control element字段发送。 MAC PDU的格式如图 9所示。
其中， 每个无线承载的业务数据填充在媒体接入控制层服务数据单元 MAC SDU ( MAC Service Data Unit )字段， 每个 MAC SDU字段在 MAC报 文头 MAC header字段中都有一个子报文头 sub-header与之相对应，其中， "R" 字段内容为预留比特， "E" 字段表示扩展字段， 以表示是否在 MAC header 有更多字段定义； "L" 字段标明对应 MAC SDU或者 MAC control element的 长度， "L" 的长度由 "F" 字段标识； "LCID"字段表示 MAC SDU字段或者 MAC Control element字段或者 padding字段对应的逻辑信道标识。
其他实施例中， 上述步骤 2中， 第一次为第一无线承载分配上行资源时， 可以根据前一个上行数据发送周期内该 RB在第二次上行资源分配中获得的 上行资源数量和该 RB对应的 PBR数量进行上行资源分配。 例如， 当前一个 上行数据发送周期内该 RB在第二次上行资源分配中获得的上行资源数量小 于该 RB对应的 PBR时， 分配给该 RB的上行资源数量为该 RB对应的 PBR 数量与前一个上行数据发送周期内该 RB 在第二次上行资源分配中获得的上 行资源数量的差值；当前一个上行数据发送周期内该 RB在第二次上行资源分 配中获得的上行资源数量大于该 RB对应的 PBR时， 则本次不再分配上行资 源给该 RB。
基于同一发明构思， 根据本发明上述实施例三提供的状态报告发送方法， 相应地， 本发明实施例四提供了一种移动终端， 其结构示意图如图 10所示， 具体包括：
确定单元 1001 , 用于确定出当前上行数据发送周期内在第二次上行资源 分配中获得上行资源或获得的上行资源数量大于设定阈值的第一无线承栽； 计算单元 1002, 用于对各无线承载组， 计算出除第一无线承载外的其余 各无线承栽对应的緩存数据量的和值；
发送单元 1003, 用于发送该和值给基站； 或者当满足设置条件时发送该 和值给基站。
较佳地， 该和值通过移动终端发送给基站的 MAC PDU中与该无线承栽 组对应的 MAC Control element字段发送。
采用实施例三和实施例四提供的方法及装置， 上述第一无线承栽获得满 足其 PBR速率要求的上行资源后再次获得了上行资源， 表示该 UE获得了满 足其各无线承载对应的 PBR速率要求外更多的上行资源， 当出现该情况时， 与发送组成该无线承载组的所有无线承载的緩存数据量的和值给基站相比， 该方法发送的和值更小， 因此， 相应的， 基站根据接收的该和值分配给该 UE 的上行资源较少， 进而可以将减少的上行资源分配给其他 UE, 避免出现已满 足各 RB对应的 PBR速率要求的 UE获得更多上行资源的同时， 还存在没有 满足各 RB对应的 PBR速率要求的 UE的情况， 达到基站更合理的分配上行 资源给各 UE的目的。
实施例五：
本发明实施例五还提供一种状态报告发送方法， 如图 11所示， 包括： 步骤 S1101、 当前上行数据发送周期内执行上行资源分配后， 移动终端确 定出无线承载对应的令牌桶中的令牌数与其对应的緩存数据量的较小值； 步骤 S1102、对各无线承载组， 计算出包含的各无线承载对应的该较小值 的和值；
步骤 S1103、发送该和值给基站； 或者当满足设置条件时发送该和值给基 站。
下面对本发明实施例五提供的状态报告发送方法进行详细阐述。
本发明实施例五中， UE側通过令牌桶机制， 将其获得的上行资源分配给 其包含的各 RB， 包括：
步骤 1 : 在上行数据发送周期到达时根据优先级比特速率 PBR更新令牌 数 Bj。
步骤 2: 按照 RB优先级从高到低的顺序为所有 Bj>0的 RB分配资源， 并根据资源分配结果更新 Bj ( Bj可以为负， 这样可以避免数据包的频繁分割 和组装）。
步骤 3: 如果仍有上行资源剩余， 则按照优先级从高到低的顺序为每个 RB分配资源 （不管 Bj值的大小）， 直到该 RB的緩存数据发送完毕或者没有 剩余上行资源。
上述步骤 1中， 对每个 RB在其对应的原 Bj上加上其对应的 PBR数量， 结杲作为更新后其对应的 Bj。
上述步骤 2中进行第一次上行资源分配， 对于当前待处理的 RB， UE根 据该 RB对应的緩存数据量 BS、 该 RB对应的 Bj和剩余上行资源数量， 确定 分配给该 RB的上行资源。 当分配上行资源给该 RB后， 相应的更新该 RB对 应的 Bj， 具体为： 在原 Bj中减去分配给该 RB的上行资源数量， 结果作为更 新后的 Bj; 相应的还更新该 RB对应的 BS， 具体为： 在原 BS中减去分配给 该 RB的上行资源数量， 结果作为更新后的 BS; 相应的还更新剩余上行资源 数量， 具体为： 在原剩余资源数量中减去分给该 RB的上行资源数量， 结果作 为更新后的剩余上行资源数量。 完成该步骤后， 如不存在避免数据包分割和 组装的情况， Bj等于零， 如存在， 则 Bj小于零。
上述步骤 3为完成步骤 2后， 如果仍有上行资源剩余时执行的步骤。 步 骤 3中进行第二次上行资源分配， 即再次分配上行资源给若干个 RB， 对于再 次获得上行资源的 RB, 相应的更新该 RB对应的 BS， 具体为， 在原 BS中减 去分配给该 RB的上行资源数量， 结果作为更新后的 BS; 相应的还更新剩余 上行资源数量，具体为：在原剩余资源数量中减去分给该 RB的上行资源数量， 结果作为更新后的剩余上行资源数量。 但对于各 RB对应的 Bj， 执行步骤 3 时， 各 RB对应的 Bj均小于等于零， 则即使 RB又获得上行资源， 也不更新 Bj。
因此， 上述步骤 S1101 中， 在当前上行数据发送周期内执行上行资源分 配后，无线承栽对应的令牌桶中的令牌数即为 UE完成上行资源分配更新后的 令牌数。 该步骤具体可以为： 获取各 RB对应的令牌数及各 RB对应的緩存数 据量， 对于每个 RB, 比较其对应的令牌数和其对应的緩存数据量的大小， 并 选取其中的最小值。
当移动终端确定出无线承载对应的令牌桶中的令牌数与其对应的緩存数 据量的较小值小于零时， 为了便于计算， 该较小值可以设置为零。
上述步骤 S1102具体可以为： 对各 RBG, 计算出包含的各 RB对应的上 述步骤 S1101中确定出的较小值的和值。
上述过程中， 对于无线承载对应的令牌桶中的令牌数与其对应的緩存数 据量的较小值小于零时，将该较小值设置为零， 则计算各 RB对应的上述步骤 S1101中确定出的较小值的和值时， 该和值为大于等于零的数值。
当无线承栽对应的令牌桶中的令牌数与其对应的緩存数据量的较小值小 于零， 该较小值按照其实际数值进行计算时， 则可能出现计算出的各无线承 栽对应的所述较小值的和值小于零的情况， 当该和值小于零时， 可以将该和 值设置为零。
上述步骤 S1103具体可以为：
每个上行数据发送周期都发送该和值给基站； 或者
满足设置条件时发送该和值给基站。 例如， 当该 RBG对应的该和值大于 设定阄值时发送该和值给基站； 或者周期地发送该 RBG的该和值给基站， 该 周期为上述发送周期的整数倍。
较佳地， 该 RBG的该和值可以通过移动终端发送给基站的媒体接入控制 层协议数据单元 MAC PDU中与 RBG对应的 MAC控制单元 MAC Control element字段发送。 MAC PDU的格式如图 9所示。
其中， 每个无线承栽的业务数据填充在媒体接入控制层服务数据单元 MAC SDU ( MAC Service Data Unit )字段， 每个 MAC SDU字段在 MAC报 文头 MAC header字段中都有一个子报文头 sub-header与之相对应，其中， "R" 字段内容为预留比特， "E" 字段表示扩展字段， 以表示是否在 MAC header 有更多字段定义； "L" 字段标明对应 MAC SDU或者 MAC control element的 长度， "L" 的长度由 "F" 字段标识； "LCID"字段表示 MAC SDU字段或者 MAC Control element字段或者 padding字段对应的逻辑信道标识。
对于各无线承载组， 当计算出包含各无线承栽对应的该较小值的和值小 于零时， 为了便于与当前规范定义的 BSR的发送格式相匹配， 可以将该和值 在与所述无线承载对应的 MAC控制单元的 BSR的内容设置为和值的绝对值， 通过该 MAC控制单元对应的 MAC 子报文头 （MAC subheader ) 中的预留比 特指示该值为负， 即采用置位的方式指示该值为负。 同样， 由于存在预留比 特位， 当计算出包含各无线承载对应的该较小值的和值大于零时， 将该和值 在与所述无线承载对应的 MAC控制单元的 BSR的内容设置为该和值， 该控 制单元对应的 MAC subheader中的预留比特指示该值为正。
基于同一发明构思， 根据本发明上述实施例五提供的状态报告发送方法， 相应地，本发明实施例六还提供了一种移动终端，其结构示意图如图 12所示， 具体包括：
确定单元 1201 , 用于当前上行发送周期内执行上行资源分配后， 确定出 无线承栽对应的令牌桶中的令牌数与其对应的緩存数据量的较小值；
计算单元 1202, 用于对各无线承载组， 计算出包含的各无线承载对应的 该较小值的和值；
发送单元 1203， 用于发送该和值给基站； 或者当满足设置条件时发送该 和值给基站。
其中， 确定单元 1201在确定无线承载对应的令牌桶中的令牌数与其对应 的緩存数据量的较小值小于零时， 将所述较小值设置为零。
计算单元 1202在包含的各无线承载对应的所述较小值的和值小于零时， 将所述和值设置为零。
较佳地， 该和值通过移动终端发送给基站的 MAC PDU中与该无线承栽 组对应的 MAC Control element字段发送。
所述发送单元 1203发送的所述各无线承载对应的所述较小值的和值小于 零时， 所述发送单元 1203将所述和值在所述无线承载组对应的 MAC控制单 元的 BSR 的内容设置为该和值的绝对值， 并在所述控制单元 MAC对应的 MAC subheader中的预留比特指示该值为负。 所述发送单元 1203发送的所述 各无线承载对应的所述较小值的和值大于零时， 将该和值在与所述无线承载 对应的 MAC控制单元的 BSR的内容设置为该和值， 所述控制单元 MAC对 应的 MAC subheader中的预留比特指示该值为正。
采用实施例五和实施例六提供的方法及装置， 发送状态报告时， 当无线 承载对应的令牌桶中的令牌数小于其对应的緩存数据量时， 分配该令牌数数 量的上行资源给该无线承载即可满足其对应的 PBR速率要求， 而当其对应的 令牌桶中的令牌数大于其对应的緩存数据量时， 分配该緩存数据量数量的上 行资源给该无线承栽即可发送该无线承栽的全部緩存数据， 若实际分配给该 无线承载的上行资源大于上述分配的上行资源， 则表示该无线承载获得了更 多的剩余上行资源， 当出现该情况时， 与发送组成该无线承载组的所有无线 承栽的緩存数据量的和值给基站相比， 该方法发送的和值更小， 因此， 相应 的 ,基站根据接收的该和值分配给该 UE的上行资源较少，进而可以将减少的 上行资源分配给其他 UE, 避免出现已满足各 RB对应的 PBR速率要求的 UE 获得更多上行资源的同时，还存在没有满足各 RB对应的 PBR速率要求的 UE 的情况， 达到基站更合理的分配上行资源给各 UE的目的。 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
