Description

一种专用调度请求资源的分配方法及装置 技术领域
本发明涉及通信技术领域, 特别是指一种专用调度请求资源的分配方法 及装置。 背景技术
长期演进(LTE ) /先进的长期演进(LTE-A )系统是一个基于调度的通信 系统, 即: 如果终端(UE )的发送緩存中有数据需要发送, 那么 UE需要先 给基站发送一个緩存状态报告(buffer status report, BSR ), 通知基站 UE的 当前的发送緩存中需要发送的数据信息。 基站在收到该 UE发送的 BSR后 , 根据该 UE要发送的数据多少以及业务类型为该 UE分配相应的上行共享信道
( UL-SCH )资源, 并通知 UE在分配的 UL-SCH资源上发送数据。
UE向基站发送 BSR也需要使用上行共享信道(UL-SCH )资源, 如果有 BSR 需要上报, 但此时没有上行共享信道资源, 那么就会触发调度请求
( Scheduling Request, SR ), 请求基站为需要发送的 BSR分配上行共享信道 资源。
触发 SR后,发送 SR的方式有两种, 即:通过专用调度请求资源(D-SR ) 发送 SR和通过随机接入过程 ( RA-SR )来进行 SR。 当 UE和基站处于同步 状态下不一定有发送 D-SR的资源, 处于非同步状态下一定没有 D-SR资源。
D-SR由 RRC分配, 由 PUCCH承栽。
一般情况下, SR发送的基本原则是:只要有 D-SR资源,就不使用 RA-SR。 并且在收到基站为 UE分配的用于发送数据的上行共享信道资源之前,可以在 能够发送 SR的资源上重复发送 SR。
在 LTE 系统中, 上行专用调度请求在 PUCCH上发送, 采用 PUCCH formatl/la/lbo对于 PUCCH formatl/la/lb, 一个符号和长度为 12的循环移位 序列相乘进行频域扩展, 形成长度为 12的符号序列, 然后再和长度为 4的正 交序列相乘进行时域扩展, 并映射到一个时隙上对应物理资源块 (PRB, physical resource block )的 12 χ 4个时频位置上, 其中有 3个符号用于传输参 考符号(reference signal, RS ), 同一个 PRB上承载的不同用户通过使用对基 序列的不同的循环移位值进行区分。
系统在每个子帧都会预留一部分 PUCCH资源作为小区专用 SR资源, 小 区内 UE共享该 PUCCH资源, 基站通过一定的资源分配策略将该小区专用 SR资源分配给小区内的各个 UE, 并通过 RRC消息将 UE专用的 SR资源的 索引、 周期、 子帧偏移位置通知给 UE, 表 1所示为 RRC消息中各个参数含 义, 该 RRC消息包括: sr-PUCCH-Resourcelndex^ sr-Configurationlndex以及 dsr-TransMax. 其中, 每个参数的含义如表所示。

LTE-A ( LTE Advanced ) 的峰值速率较 LTE有很大的提高, 要求达到下 行 IGbps, 上行 500Mbps。 同时, LTE-A系统要求和 LTE系统有很好的兼容 性。基于提高峰值速率、与 LTE系统兼容以及充分利用频谱资源的需要, LTE-A 系统引入了栽波聚合(CA, Carrier Aggregation )技术。
载波聚合技术是指在一个小区内上下行各包含多个成员载波,而不是 LTE 系统以及之前的无线通信系统中只有一套载波的模式。 在载波聚合的系统中 各个成员栽波可以是连续或非连续的, 为了和 LTE系统兼容, 每个成员载波 的最大带宽为 20MHz, 各成员栽波间的带宽可以相同或不同。
主载波定义: LTE-A 系统中上行支持多个成员载波, 主载波的概念目前 没有明确定义, 可能是 cell-specific的, 也可能是 UE-specific的。 如果主载波 本发明实施例是在多载波聚合系统中, 根据设定的调度原则为终端选择 栽波资源作为该终端的专用调度请求资源, 并指定利用所选择上行成员载波 进行专用调度请求的时频资源; 将所述载波资源和所述时频资源通知所述终 端, 实现了在多栽波聚合系统中为终端配置专用调度请求的时域和频域资源。 附图说明

本发明实施例是在多载波聚合系统中, 根据设定的调度原则为终端配置 载波资源, 并在配置的载波资源上分配对应的时频资源, 将所述载波资源和 所述时频资源作为专用调度请求资源;
将所述载波资源和 /或所述时频资源通知所述终端。
参见图 1所示, 本发明实施例的方法包括以下步骤: 步骤 101: 在多载波聚合系统中,根据设定的调度原则为终端配置载波资 源, 并在配置的栽波资源上分配对应的时频资源, 将所述载波资源和 /或所述 时频资源作为专用调度请求资源。
这里, 根据设定的调度原则为终端选择载波资源可以这样实现: 可以根 据终端的能力信息随机选择载波资源, 可以根据负荷均衡原则选择载波资源, 也可以选择当前主载波作为该终端的专用调度请求资源。 选择的载波资源可 以包括一个或多个上行成员栽波。
所述专用调度请求资源可以是: 为所述终端在任意时刻分配一个上行成 员栽波的时频资源信息, 也可以是在设置的任意时刻分配多个上行成员栽波 的时频资源信息。
当选择多个上行成员载波时, 可以配置终端在每个上行成员载波都可以 进行专用调度请求, 也可以配置终端在一个子帧中只能利用一个上行成员载 波进行专用调度请求, 并且终端不同的子帧在每个上行成员载波上进行跳频。
步骤 102: 将所述栽波资源和所述时频资源通知所述终端。
下面举具体实施例详细说明本发明的实现方案。
参见图 2所示, 本实施例是以基站根据终端的能力来选择上行成员载波 的实现方案, 具体如下:
步骤 201: 基站根据终端上报的能力信息,确定该终端支持的上行成员载 波。 终端上报的能力信息中包括该终端支持的上行成员载波信息。
步骤 202:从该终端支持的上行栽波成员中随机选取一个上行成员载波作 为该终端的专用调度请求的栽波资源。
步骤 203: 在所选上行成员载波上为终端分配用于承栽专用调度请求的 PUCCH资源编号;
步骤 204: 为终端确定其专用调度请求发送的周期和偏移量。 步骤 203和 204分配的 PUCCH资源编号和确定的周期和偏移量即为该终端配置的时频资 源信息。
步骤 205: 通过扩展后的 RRC消息将选择的上行成员载波和 /或配置的时 ,
频资源信息通知给该终端。
对现有 RRC消息需要增加成员栽波指示域, 扩展后的 RRC消息包括: 频域资源指示域和时频资源指示域, 其中, 所述频域资源指示域用于保存专 用调度请求资源载波信息, 所述时频资源指示域: 用于保存专用调度请求的 时频信息。 所述时频资源信息包括: 专用调度请求使用的 PUCCH资源编号、 周期以及偏移量。 所述载波信息包括: 进行专用调度请求的载波编号或进行 上行成员栽波的频点信息。 进一步, 所述 RRC消息还可以包括专用调度请求 最大传输次数。
例如: 表 2所示为扩展后的 RRC消息。 参见表 2所示, 在本发明实施例 中, 相对于 LTE R8版本的协议 SR配置信息单元, 增加了一个参数, 即 UE 专用 D-SR资源的编号(sr-Componetcarrier ), 扩展后的 RRC消息至少包括: UE 专用 D-SR 资源的编号 ( sr-Configurationlndex )、 周期和偏移 ( sr-Componetcarrier )。 sr-Componetcarrier表示指定 SR使用的成员载波编号。 sr-Configurationlndex表示 D-SR传输的周期和子帧偏移, 根据该参数以及 D-SR资源配置的起始子帧可以确定 UE传输 D-SR使用的具体子帧。
进一步还可以包括: dsr-TransMax, 用于表示 D-SR的最大传输次数, 该 参数的目的是增加 D-SR的可靠性。
需要注意如果选择的载波资源是主载波, 那么 RRC信令中可以不携带该 载波指示信息。
Figure imgf000007_0001
表 2
参见图 3 所示, 本实施例是以配置主载波为终端专用调度请求资源的例 子, 具体如下:
步骤 301: 基站将主载波配置为该终端的专用调度请求的载波资源。
如果上行主载波采用终端专用 (UE-specific )形式, 则基站可以根据 UE 确定使用该终端的专用主载波作为专用调度请求资源的发送栽波。 如果上行 主载波采用小区专用(cell-specific )形式,则基站可以指定使用该 cell-specific 主载波作为该终端的专用调度清求资源。
步骤 302: 在主载波上为终端分配用于承栽专用调度请求的具体的
PUCCH资源编号;
步驟 303: 为终端确定其专用调度请求发送的周期和偏移量。
这里,分配的 PUCCH资源编号和确定的周期和偏移量即为该终端配置的 时频资源信息。
步骤 304: 通过 RRC消息将配置的主栽波和 /或时频资源的信息通知给该 终端。
这里, 通过 RRC消息通知 UE专用 D-SR资源的编号、 周期和偏移, 因 为 UE在发送 SR之前已经知道哪个上行成员栽波为主载波, 所以可以采用现 有 RRC消息, 无需进行扩展。
参见图 4所示, 本实施例是以负荷均衡原则选择栽波资源为例说明本发 明的方案, 具体如下:
步骤 401: 基站根据终端上报的能力信息,确定该终端支持的上行成员载 波。
步骤 402: 根据该终端支持的上行成员载波上的负荷信息,按照负荷均衡 的原则, 从该终端支持的上行成员载波中选择一个上行成员载波作为作为该 终端的专用调度请求资源。
步驟 403:在所选上行成员载波上为终端分配用于承载专用调度请求的具 体的 PUCCH资源编号;
步骤 404: 为终端确定其专用调度请求发送的周期和偏移量, 即配置终端 在选取的上行成员载波上利用哪个子帧进行专用调度请求。 步骤 405: 通过 RRC消息将选择的上行成员载波和 /或配置的时频资源信 息通知给该终端。
这里, 可以对现有 RRC消息需要增加成员载波指示域, 与 2所示实施例 相同, 具体可以参见表 2所示。
参见图 5 所示, 本实施例是以分配跳频方式的专用调度资源为例说明本 发明的方案, 在本实施例中, 专用调度倚求可以按照子帧时序在部分上行成 员载波集合或者全部上行成员载波集合内跳频, 但是在一个子帧内只在一个 上行成员载波上分配专用调度请求资源。 具体如下:
步骤 501: 根据终端上报的能力信息, 确定该终端支持的上行成员载波。 步骤 502: 在该终端支持的上行成员载波中选择一个以上上行成员载波, 步骤 503:在所选上行成员载波上为终端分配用于承载专用调度请求的具 体的 PUCCH资源编号;
步骤 504: 为终端确定其专用调度请求发送的周期和偏移量。
步骤 503分配的 PUCCH资源编号和步骤 504确定的周期和偏移量即为该 终端配置的时频资源的信息。
比如: 基站在 UE支持的上行成员载波中选择 N个, 其中 N大于 1小于 等于 UE可以支持的上行成员载波的个数,并按照一个子帧内只使用一个成员 载波, 不同子帧内在各个成员载波之间做切换的原则确定各个子帧内分配专 用 SR资源的栽波;
参见图 6所示, 基站为终端选择了四个上行成员载波作为专用调度请求 资源, 比如: CC1、 CC2、 CC3和 CC4。 并且为 CC1配置对应的子帧为上行 子帧 1、 上行子帧 5以及上行子帧 9, 为 CC2配置对应的子帧为上行子帧 2、 上行子帧 6, 为 CC3配置对应的子帧为上行子帧 3、 上行子帧 7, 为 CC4配 置对应的子帧为上行子帧 4和上行子帧 8。
也就说, 终端按照上述配置, 可以在上行子帧 1、 5、 9上利用 CC1进行 专用调度请求, 在上行子帧 2和 6上利用 CC2进行专用调度请求, 在上行子 帧 3和 7上利用 CC3进行专用调度请求。 是 cell-specific的, 则所有支持 R10的 UE必须支持主载波; 如果主载波是 UE-specific的, 则该 UE—定支持自己的主载波。
引入 CA技术后, 由于上行同时支持多个成员载波,需要考虑在多个成员 载波的情况下如何配置 UE专用的 D-SR资源, 目前标准中尚无相关描述。 发明内容

参见表 3所示, 在本实施例中, 需要对现有的 RRC消息进行扩展, 扩展 后的 RRC消息需要增加跳频方式指示( hopping-mode )域和跳频成员载波集 合指示(cc-group )域, 其中, 所述跳频成员载波集合指示域用于保存该终端 的跳频成员集合, 所述跳频方式指示域用于保存在每个调频集合中的载波对 应的时频信息。 所述载波信息包括: 专用调度请求资源的编号或作为该终端 的专用调度请求资源的上行成员载波频点信息。 当然, 如果只有一种预定义 跳频模式, 则可以省略跳频方式指示域。
