持久资源的处理方法、 终端以及基站 技术领域
本发明涉及通信领域, 具体而言, 涉及一种持久资源的处理方法、 终 端以及基站。 背景技术
在通信***中, 基站(Base Station, BS )是指给终端提供服务的设备, 基站通过上下行链路与终端进行通信, 下行(前向)是指基站到终端的方 向, 上行(反向)是指终端到基站的方向。 多个终端可同时通过上行链路 向基站发送数据, 也可以通过下行链路同时从基站接收数据。
在通信标准的制定过程中, 如何有效地降低通信***控制开销以增加 整个***的吞吐量受到越来越多公司的关注。 对于周期性且数据包大小及 调制编码速率( MCS )相对不变的业务, 通常采用一种持久分配( Persistent Allocation, PA ) 的方法来管理资源。 在周期性业务开始时, 基站分配固定 的资源给终端, 并且发送相应的包含 PA分配内容的控制消息给终端, 此资 源分配消息仅在开始时发送一次, 之后终端利用分配给其的固定资源来接 收或发送数据, 直到资源释放、 或者资源改变、 或者信道状况发生变化等 情况出现时才终止本次的 PA分配, 由此可见, PA分配的方法能够大大减 少资源分配的控制消息的开销。
在电气和电子工程师十办会 ( Institute for Electrical and Electronic Engineers , IEEE ) 802 系列标准的制定过程中, 对资源持久分配技术做了 相关的描述, 该技术的设计初衷是节省对具有特定传输周期且数据包长相 对固定的终端资源分配描述开销来改善***的性能, 包括消息定义、 空洞 填补、 资源去分配、 资源分配等内容。 但是, 由于资源持久分配消息 (PA MAP )发送的周期比较长, 所以终端能否正确接收到该消息至关重要, 终 端需要向基站反馈确认 MAP消息的接收情况。 当终端接收到新的 PA分配 时, 向基站发送正反馈确认(ACK )消息(也可以称为正确应答消息); 当 终端解码 MAP消息出现错误时, 向基站发送负反馈(NACK )消息(也可 以称为错误反馈消息)。 基站根据终端的反馈情况来确定如何调整持久资源 的分配。
图 1 是根据相关技术的终端接收下行或上行资源持久分配时的资源使 用示意图, 其中图 1中的 (a )是基站向终端分配下行持久资源的过程, 如 图 1中的 (a )所示, 基站在第 (k - 4 ) 帧发送资源持久分配消息, 为终端 MS1、 MS2、 MS3分配下行持久资源, 由于 MS3没有成功接收到该 MAP 消息, 则 MS3不会去解码基站在第 (k - 4 )帧的下行持久资源上发送的数 据, 造成下行资源的浪费, 图 1 中的 (b)是基站向终端分配上行持久资源的 过程, 基站在第 (k - 4 ) 帧发送资源持久分配消息, 为终端 MS1、 MS2、 MS3分配上行持久资源, 由于 MS1没有成功接收到该 MAP消息, 则 MS1 不会在第 (k - 4 ) 帧的上行持久资源上发送上行数据, 造成上行资源的浪 费。
图 2是根据相关技术的在终端接收映射消息失败的情况下资源块移动 的示意图, 图 2描述了填补资源空洞的处理过程。 如图 2所示, BS在第 K 帧( Frame K )发送 MAP消息来指示 MS1释放资源以及具体的资源块位置 和大小, 并且 BS指明需要填补空洞, 此时 BS和 MS就按照空洞填补后的 资源位置来收发数据。具体来看,就是 MS2和 MS3移动其资源块位置来填 补 MS1释放资源后造成的空洞。 如图 2所示, MS2在 frame K解码 MAP 消息出错, 于是 MS2立即停止数据收发, 并在两帧后发送 NACK给 BS , BS将发送新的 MAP消息来指示 PA恢复(在 frame K+4时刻 )。在 PA恢复 之前, MS2的数据就丟失了。 如果 MS2解析 MAP消息出错而不停止收发 数据, 那么 MS3移动其资源块位置后将与 MS2的资源块位置冲突, MS2 和 MS3都不能正常收发数据。 在填补空洞而移动资源位置的处理当中, 在 没有得到 MS接收 MAP消息反馈确认的情况下就已经开始应用新的 PA, 因此, 一旦 MAP消息解码错误就会导致数据丟失或出错。
针对相关技术中导致数据丟失或出错的问题, 目前尚未提出有效的解 决方案。 发明内容

考虑到相关技术中的数据丟失或出错的问题, 本发明提出一种数据通 信***中资源持久分配异常情况的处理方案, 采用了资源持久分配延迟生 效的方案, 终端接收来自基站的资源持久分配消息之后, 在资源持久分配 消息的生效时间到达时, 终端根据该资源持久分配消息处理持久资源, 可 以解决***频谱效率下降的问题。
方法实施例一
需要说明的是, 在附图的流程图示出的步骤可以在诸如一组计算机可 执行指令的计算机***中执行, 并且, 虽然在流程图中示出了逻辑顺序, 但是在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤。
本发明实施例提供了一种持久资源的处理方法, 图 10是根据本发明实 施例的持久资源的处理方法的流程图, 如图 10所示, 该流程包括如下的步 骤 S102至步骤 S104:
步骤 S102, 终端接收来自基站的资源持久分配消息, 其中, 该资源持 久分配消息用于指示基站预分配或去分配给终端的持久资源。
步骤 S104, 如果终端接收到来自基站的资源持久分配消息, 则在资源 持久分配消息的生效时间到达时, 终端根据该资源持久分配消息处理持久 资源, 其中, 生效时间用于指示对持久资源进行处理的开始时间。
在步骤 S104中, 终端根据资源持久分配消息处理持久资源包括: 如果 该资源持久分配消息用于指示基站预分配给终端的持久资源, 则终端通过 该持久资源进行数据的接收和 /或发送; 如果该资源持久分配消息用于指示 基站去分配给终端的持久资源, 接收到资源持久分配消息的多个终端中符 合条件的终端根据资源持久分配消息进行资源移位, 上述符合条件的终端 包括: 持久资源索引大于、 或小于被取消的已分配持久资源索引的终端。

需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中的 特征可以相互组合。 下面将参考附图并结合实施例来详细说明本发明。
该实施例可以通过以下方式实现, 其中, 方式一对应实施例一和实施 例二, 方式二对应实施例三和实施例四, 方式三对应实施例五。
方式一
方式一与实施例一和实施例二相对应, 该方式一是: 基站通过资源持 久分配消息给终端分配持久资源, 终端根据其缺省配置的资源持久分配消 息的生效时间到达时通过持久资源进行数据的接收或发送(即, 资源持久 分配延迟生效)。 基站可以通过单播、 组播、 或广播方式发送资源持久分配 消息。 需要说明的是, 终端和 /或基站的缺省配置中可以包括上述的生效时 间。
其中, 缺省配置的生效时间可以在终端反馈成功接收资源持久分配消 息的信息的时间之后, 也可以在基站接收终端反馈成功接收资源持久分配 消息的信息的时间之后。
在时分双工***中, 如果基站为终端分配下行持久资源, 缺省配置的 生效时间不会位于和基站发送资源持久分配消息的下行子帧相连续的下行 子帧之内, 即, 生效时间位于和基站发送资源持久分配消息的下行子帧相 连续的下行子帧之外。
下面结合图 3说明该方式一, 图 3为是根据本发明实施例的资源持久 分配延迟生效的流程图 (默认生效时间), 如图 3所示, 该流程包括如下的 步骤 S302至步骤 S304:
步骤 S302, 基站通过资源持久分配消息给终端分配持久资源; 步骤 S304 , 终端接收到基站发送的资源持久分配消息后, 根据缺省配 置的资源持久分配消息的生效时间, 当该生效时间到达时利用持久资源进 行数据的接收或发送。
下面结合实施例一、 实施例二进一步说明图 3所示的流程。
实施例一
图 4是根据本发明实施例的终端接收下行或上行资源持久分配时的资 源延迟使用示意图, 在图 4中 (a )所示的时分双工***中, 基站在第 k帧 ( frame k ) 中通过控制消息 ( Persistent Allocation Advanced-MAP , PA Α-ΜΑΡ )向终端 MSI、 MS2、 MS3分配下行持久资源, 为了防止 MSI、 和 /或 MS2、 和 /或 MS3不能成功获得 PA A -MAP消息造成 frame k中分配的 持久资源的浪费, 因此, 基站延迟使用为上述终端分配的持久资源, 假设 标准缺省配置的时间为 3个 frame,则 frame k分配的下行持久资源在 frame ( k+3 ) 中生效, 如果基站在 frame k中的上行反馈信道(反馈信道也可以 位于其它后续帧上 )上收到 MSI、 MS2反馈的成功接收 PAA-MAP的信息, 而没有得到 MS3反馈的成功接收 PAA-MAP的信息, 则在 frame ( k+3 )中 只保留为 MS1、 MS2分配的下行持久资源,之前预分配给 MS3的下行持久 资源可以分配给其它终端使用。
上述示例过程中也可以以子帧 (subframe )或超帧 ( superframe ) 为单 位, 同样上述过程也适用于频分双工、 半频分双工***。
在时分双工***中, 当以 subframe 为单位时, 如果一段连续下行 subframe集合 (该集合中没有上行 subframe ) 中第一个 subframe上发送下 行资源持久分配消息,则分配的下行持久资源的生效时间不会在该 subframe 集合中。
实施例二
在图 4中( b )所示的时分双工***中,基站在 frame k中通过 PA A-MAP 向终端 MS1、 MS2、 MS3分配上行持久资源, 基站延迟使用为上述终端分 配的持久资源, 假设标准默认的时间为 1个 frame , 贝 frame k分配的上行 持久资源在 frame ( k+1 ) 中生效, 如果基站在 frame k中的上行反馈信道 上收到 MS2、 MS3反馈的成功接收 PA A-MAP的信息, 而没有得到 MS1 反馈的成功接收 PAA-MAP的信息, 此时基站可以认为 MS1没有成功接收 PA A-MAP信息, 则在 frame ( k+1 ) 中只保留为 MS2、 MS3分配的上行持 久资源, 之前预分配给 MS1的上行持久资源可以分配给其它终端使用。
上述过程中也可以以 subframe或 superframe为单位, 同样上述过程也 适用于频分双工、 半频分双工***。
方式二
方式二与实施例三和实施例四相对应, 该方式二是: 基站通过资源持 久分配消息给终端分配持久资源,资源持久分配消息包含生效时间字段(生 效时间字段也可以是分配周期字段, 此时基站或终端在持久资源上开始进 行数据发送或接收的时间与分配周期字段有关, 分配周期可写为 allocation period ), 终端根据生效时间字段确定的生效时间到达时利用持久资源进行 数据的接收或发送(即, 资源持久分配延迟生效)。 基站可以通过单播、 组 播、 或广播方式发送资源持久分配消息。
需要说明的是, 上述的生效时间字段可以直接或者间接的指示生效时 间。
其中, 生效时间可以在终端反馈成功接收资源持久分配消息的信息的 时间之后, 也可以在基站接收终端反馈成功接收资源持久分配消息的信息 的时间之后。
在时分双工***中, 如果基站为终端分配下行持久资源, 生效时间不 会位于和基站发送资源持久分配消息的下行子帧相连续的下行子帧之内。
下面结合图 5说明该方式二, 图 5是根据本发明实施例的资源持久分 配延迟生效的流程图 (消息中包含生效时间字段)如图 5所示, 该流程包 括如下的步骤 S502至步骤 S504:

步骤 S504, 终端接收到资源持久分配消息后, 根据该消息中的生效时 间字段确定的生效时间, 当该生效时间到达时利用持久资源进行数据的接 收或发送。
下面结合实施例三、 实施例四进一步说明图 5所示的流程。
实施例三
图 6是根据本发明实施例的终端接收下行或上行资源持久分配时的资 源延迟使用示意图, 在图 6中(a )所示的时分双工***中, 基站在 frame k 中通过控制消息 PAA-MAP向终端 MS1、 MS2、 MS3分配下行持久资源, 基站延迟使用为上述终端分配的持久资源, 假设 PA A-MAP中的生效时间 字段指示为本 frame分配的持久资源在 2个 frame后生效, 则 frame k分配 的下行持久资源在 frame ( k+3 ) 中生效, 如果基站在 frame k中的上行反 馈信道(反馈信道也可以位于其它后续帧上)上收到 MS1、 MS2反馈的成 功接收 PAA-MAP的信息, 而没有得到 MS3反馈的成功接收 PAA-MAP的 信息, 则在 frame ( k+3 ) 中只保留为 MSI、 MS2分配的下行持久资源, 之 前预分配给 MS3的下行持久资源可以分配给其它终端使用。
上述示例过程中也可以以 subframe或 superframe为单位, 同样上述过 程也适用于频分双工、 半频分双工***。
在时分双工***中, 当以 subframe 为单位时, 如果一段连续下行 subframe集合 (该集合中没有上行 subframe ) 中第一个 subframe上发送下 行资源持久分配消息,则分配的下行持久资源的生效时间不会在该 subframe 集合中。
实施例四 在图 6中( b )所示的时分双工***中,基站在 frame k中通过 PA A-MAP 向终端 MS1、 MS2、 MS3分配上行持久资源, 基站延迟使用为上述终端分 配的持久资源,假设 PAA-MAP中的生效时间字段指示为本 frame分配的持 久资源在下一 frame中生效,则 frame k分配的上行持久资源在 frame ( k+1 ) 中生效, 如果基站在 frame k中的上行反馈信道上收到 MS2、 MS3反馈的 成功接收 PA A-MAP的信息, 而没有得到 MS1反馈的成功接收 PA A-MAP 的信息, 此时基站可认为 MS1没有成功接收 PA A-MAP信息, 则在 frame ( k+1 ) 中只保留为 MS2、 MS3分配的上行持久资源, 之前预分配给 MS 1 的上行持久资源可以分配给其它终端使用。
上述示例过程中也可以以 subframe或 superframe为单位, 同样上述过 程也适用于频分双工、 半频分双工***。
方式三
方式三与实施例五相对应, 该方式三是: H没终端已获得持久分配资 源和资源持久分配消息接收错误反馈信道, 以下是通信***中持久资源去 分配时资源移位延迟生效方法。
基站通过资源持久分配消息取消已分配的持久资源并要求进行资源移 位, 接收到资源持久分配消息的一个或多个终端中符合条件的终端根据缺 省配置的生效时间到达时进行资源移位。 其中, 符合条件的终端是指分配 的持久资源索引大于、 或小于被取消的已分配的持久资源索引的终端。 基 站可以通过单播、 组播、 或广播方式发送资源持久分配消息。 需要说明的 是, 终端和 /或基站的缺省配置中可以包括上述的生效时间。
需要说明的是, 也可以在资源持久分配消息中包含生效时间字段(生 效时间字段也可以是分配周期字段, 此时基站或终端在持久资源上开始进 行数据发送或接收的时间与分配周期字段有关, 分配周期可写为 allocation period ), 该生效时间字段用于指示生效时间。 其中, 缺省配置的生效时间可以在在终端反馈成功接收资源持久分配 消息的信息的时间之后, 也可以在终端反馈未成功接收资源持久分配消息 的信息的时间之后。
下面结合图 7说明该方式三, 图 7是根据本发明实施例的持续资源去 分配时空洞填补延迟生效的流程图, 图 7描述了资源持久分配延迟生效的 实现流程, 假设终端已获得持久分配资源和资源持久分配消息接收错误反 馈信道, 如图 7所示, 该流程包括如下的步骤 S702至步骤 S705:
步骤 S702, 基站通过资源持久分配消息取消已分配的持久资源并要求 进行资源移位;
步骤 S704, 终端接收到基站发送的资源持久分配消息后, 接收到资源 持久分配消息的一个或多个终端中符合条件的终端根据该校中缺省配置的 生效时间, 在该生效时间到达时进行资源移位。
下面结合实施例五进一步说明图 7所示的流程。
实施例五
图 8是根据本发明实施例的在终端接收映射消息失败的情况下资源块 延迟移动的示意图,如图 8所示, BS在第 k帧发送包含需要资源移位的 PA A-MAP, 指示释放 MS1的资源块以及资源块的位置和大小, 并指明其他符 合条件的 MS要移动其资源块位置来填补资源块释放造成的空洞。 假设标 准默认的延迟生效时间下一持续资源使用周期到达时刻, 即第 (k+4 ) 帧。
如图 8所示, MS1、 MS3成功接收到基站发送的 PA A-MAP, MS2没 有成功接收基站发送的 PA A-MAP, MS2将在第 ( k+2 ) 帧发送反馈消息 NACK以通知 BS。 第 k帧中, MS2、 MS3都按照原有的 PA分配来接收数 据, 相应的, BS也按照原有的 PA分配来发送数据。
MS3将在第 (k+4 ) 帧中移动资源块并启用新的资源位置来接收数据, 相应的, BS也在第 (k + 4 ) 帧启用新的资源位置来发送数据。 对于在第 (k + 4 ) 帧中获得 PA-MAP消息的 MS2而言, 可以在第 (k + 4 )帧移动资源块并启用新的资源位置来接收数据,相应的, BS也在第(k + 4 )帧启用新的资源位置来发送数据; 或者在第 (k + 4 )帧及以后停止使 用持续资源。
对于在第( k + 4 )帧中未获得 PA-MAP消息的 MS2而言, 在第( k + 4 ) 帧及以后停止使用持续资源。
图 9是根据本发明实施例的资源持久分配消息接收错误处理方法流程 图, 假设终端已获得持久分配资源和数据反馈信道, 如图 9所示, 该流程 包括如下的步骤 S902至步骤 S904:
步骤 S902, 基站通过资源持久分配消息给取消给上述终端已分配的下 行持久资源, 并暂不分配之前给上述终端分配的数据反馈信道给其它终端; 步骤 S904, 如果基站在数据反馈信道上成功获得数据接收成功、 或数 据接收失败的反馈信息, 则该基站可认为终端没有成功接收所述资源持久 分配消息。
