可选的, 根据所述 MAC层配置参数, 进行独立的上行调度包括: 当 MAC 实体为一个时, 当进行新数据传输, 根据第一映射关系与第二 映射关系, 调度映射到上行授权资源对应的物理实体 /小区的逻辑信道的上行 数据; 或者,
当 MAC 实体为至少两个时, 当进行新数据传输, 根据第三映射关系与 第四映射关系, 调度映射到上行授权资源对应的物理实体 /小区的逻辑信道的 上行数据。
其中, 调度的具体方法可以包括:
首先, 根据逻辑信道优先级, 按照逻辑信道优先级从高到底的顺序为映 射到该上行授权资源对应的物理实体 /小区, 并且允许传输数据量大于零的逻 辑信道分配资源。
分配资源的方法为: UE将资源分配给最高优先级的逻辑信道的数据进行 上行传输。只有当更高优先级逻辑信道允许传输数据量小于等于零, UE才将 剩余的资源分配给低优先级的逻辑信道进行数据传输。
其次, UE从该逻辑信道的允许传输数据量中减去已传输数据量。
再次, 当全部映射到该上行曼权资源对应的物理实体 /小区的逻辑信道的 允许传输数据量都小于等于零, 并且, 上行传输资源仍有剩余, UE按照逻辑 信道优先级从高到底的顺序为映射到该上行授权资源对应的物理实体 /小区
分配上行资源。 UE将资源分配给最高优先级的逻辑信道的数据进行上行传 输。 只有当更高优先级逻辑信道全部传输完, UE才将剩余的资源分配给低优 先级的逻辑信道进行数据传输。 当 UE将全部逻辑信道数据传输完毕, 或者 将上行传输资源耗尽, UE结束上行调度。

另外, 可选的, 基站也可以根据 MAC层配置参数在基站侧执行相应的 MAC功能。 其中, 基站执行的 MAC层功能与 UE执行的 MAC层功能相对 应, 例如在上行数据传输时, UE将上行逻辑信道映射到上行传输信道, 将上 行传输信道映射到上行物理层信道, 并完成上行数据的调度, 基站将上行物 理层信道映射到上行传输信道, 将上行传输信道映射到上行逻辑信道, 并完 成下行数据的调度。

本实施例通过配置至少两组的映射关系, 根据不同组的映射关系就可以
将不同的逻辑信道 /RB映射到不同的传输信道 /MAC实体和 /或小区 /物理实体 上, 满足多流传输场景的需求, 提高 MAC层传输效率。
下面以 LTE场景, 且接入节点为 LPN为例, 对本发明实施例的方法进 行描述。
图 3为本发明多流传输的调度方法另一实施例的流程示意图, 本实施例 以配置多个 MAC实体为例, 参见图 3 , 包括:
步骤 31 : 基站根据分流策略为 UE配置至少两个的 MAC实体, 以及每 个 MAC实体对应的 MAC层配置参数。
其中, 分流策略可以是将用户面数据与控制面数据分离传输, 此时, 参 见图 4, 将 SRB数据放在宏小区 ( LTE eNB )传输, 将 DRB数据放在 LPN 小区中传输。
或者, 分流策略也可以是将数据量小和 /或服务质量( Quality of Service, QoS )要求高的 RB数据放在宏小区传输,将数据量大和 /或 QoS要求低的 RB 数据放在 LPN小区传输, 例如, 参见图 5 , 将 SRB0数据、 SRB1数据、 VoIP 数据放在宏小区传输, 将文件传输协议 ( File Transfer Protocol, FTP )数据放 在 LPN小区传输。
配置的 MAC实体的个数可以与分流的数据流数相同, 例如, 图 4或图 5 所示的分流在宏小区和 LPN小区中传输时, 则可以配置两个 MAC实体, 分 別用于映射到宏小区和 LPN小区。
具体的每个 MAC实体对应的 MAC层配置参数可以根据具体的分流策略 确定, 例如将 SRB0和 SRB1放在宏小区中传输, 将 SRB2放在 LPN小区中 传输时, 如果 SRB0、 SRB1、 SRB2对应的逻辑信道分别为 CCCH、 逻辑信道 标分别为 1和 2的 DCCH, 下文分别表示为 DCCH1和 DCCH2, 那么就可以 将 CCCH和 DCCH1映射到宏小区的传输信道, 而将 DCCH2映射到 LPN小 区的传输信道, 传输信道上行时为上行共享信道( Uplink Shared Channel, UL-SCH ) , 下行时为下行共享信道(Downlink Shared Channel, DL-SCH ) 。
本实施例中, 配置了多个 MAC实体, 每个 MAC实体对应一组 MAC层 配置参数。 其中的每组 MAC层配置参数可以包括如下项中的至少一项:
(1) MAC实体标识( MAC-Entity-identity ),用于标识一个 UE的 MAC实体, 方便 MAC实体增加 /删除 /重配置。 该标识可以是整数 ( INTEGER )类型。 例
如,
MAC-Entity-identity INTEGER(O..X),
(2) MAC实体 /传输信道与小区 /物理( PHY ) 实体的映射关系。 该映射 关系表示 MAC传输信道映射到该小区 /PHY实体的物理层信道,用于表征传输 信道与物理层信道的映射关系。 例如:
以 MAC实体为例, 与小区或物理实体的映射关系可以分别表示如下: MAC-Entity-mapping-with-cell Cell-identity
或者 , MAC-Entity-mapping-with-PHY-entity PHY-entity-identity 以 "MAC-Entity-mapping-with-cell Cell-identity" 为例, 通常信息单元 由名称和类型组成, 前面的 "MAC-Entity-mapping-with-ceir 表示名称, 后 面的 "Cell-identity"表示类型, 也就是该 MAC实体(可以用前面的 MAC实体 标识表示)映射到的具体的 cell的标识。 后续类似表达的具体含义可以参照此 处的描述。
其中 Cell-identity可以是任何一种小区标识, 例如物理小区标识( Physical Cell Identity, PCI )、 公共陆地移动网 ( Public Land Mobile Network, PLMN ) 范围内唯一的小区标识、 演进的 UMTS 陆地无线接入 ( Evolved-UMTS Terrestrial Radio Access , EUTRA ) 小区全局标 ·ί只 ( Evolved Cell Global Identifier, ECGI )、 物理小区标识与载波频点信息或者小区索引号等。 其中, 小区索引号可以是当前已配置小区的索引 (cellindex )。 该索引信息可以把全 部配置小区进行索引。 PHY实体标识 ( PHY-entity-identity ) 为唯一标识 PHY 实体的标识, 该标识可以是 INTEGER类型。
(3) MAC实体 /传输信道与逻辑信道 /RB映射关系。该映射关系表示逻辑信 道 /RB映射到该 MAC实体, 用于表征传输信道与逻辑信道的映射关系。 例如:
Logical-and-transport-mappingList:: = SEQUENCE SIZE ( 1..maxLogicalChannelNum)) OF Logical-and-transport-mapping
Logical-and-transport-mapping ::= SEQUENCE { logicalChannelldentity logicalChannelldentity
}
上述内容也是用于表述逻辑信道与传输信道映射关系的具体表达方式, 例如, 映射到上述的 MAC实体标识指示的 MAC实体的逻辑信道包括
maxLogicalChannelNum个, 每个逻辑信道可以具体可以表示为 " logicalChannelldentity logicalChannelldentity,, , 其 中 , 前 面 的 " logicalChannelldentity " 为名 称, 即要描述的是什么 ; 后面的 "logicalChannelldentity" 为类型, 即具体的逻辑信道的标识。 后续类似表达 的具体含义可以参照此处的描述。
还可以用 RB标识( srb-Identity/drb-identity )代替逻辑信道标识来表示映 射关系。
Logical-and-RB-mappmgList:- SEQUENCE SIZE (L.maxRBNum)) OF Logical-and- RB-mapping
Logical-and-RB-mapping:: = SEQUENCE {
RB-identity RB-identity
}
(4) MAC相关参数
该 MAC参数可以包含全部或部分 MAC层配置参数。例如, DRX机制参数、 HARQ最大重传次数(maxHARQ-Tx )、 SPS配置参数等。
步驟 32: 基站向 UE发送专用信令, 该专用信令中包含对 MAC实体的 处理方式以及该 MAC实体对应的 MAC层配置参数。
其中, 处理方式可以是增加、 删除或者重配置一个或多个 MAC 实体, 增加、删除或修改的 MAC实体对应的 MAC层配置参数就是专用信令中包含 的 MAC层配置参数。
特别的, 对于用于删除 MAC层配置参数的专用信令中可以只包括删除 MAC实体标识(MAC-Entity-identity )。
步骤 33: UE根据专用信令, 对相应的 MAC实体进行处理。
其中, 根据专用信令的指示, 可以增加、 删除或重配置 MAC 实体, 在 具体配置时可以才艮据每个 MAC实体对应的 MAC层配置参数完成。
步驟 34: UE根据每个处理后的 MAC实体对应的 MAC层配置参数, 分 别执行 MAC功能。
其中, 当配置了多个 MAC实体后, 这些 MAC实体之间是相互独立的执 行 MAC层功能, 每个 MAC实体执行的 MAC功能可以包括如下项中的至少 一项:
(1)上行传输信道映射
参见图 6, MAC实体根据自身对应的 MAC层配置参数中的 MAC实体 /传输 信道与 i2_辑信道 /RB映射关 系 ( Logical-and-transport-mappingList/ Logical-and-RB-mappingList ), 将上行逻辑信道映射到对应的上行传输信道。
(2)下行传输信道映射
参见图 7, MAC实体根据自身对应的 MAC层配置参数中的 MAC实体 /传输 信道与 i£辑信道 /RB映射关 系 ( Logical-and-transport-mappingList/ Logical-and- B-mappmgList ), 将下行逻辑信道映射到对应的下行传榆信道。
(3)上行物理层信道映射
MAC实体根据自身对应的 MAC层配置参数中的 MAC实体 /传输信道与小 区 /PHY实体的映射关系, 将上行传输信道映射到上行物理层信道。 特别的, 一个 MAC实体可以映射到一个或多个小区 /物理实体。 例如, 将 MAC实体 1
(即, MAC-Entity-identity为 1 )映射到小区索引 1与小区索引 2的小区。 此时, MAC实体 1对应的 UL-SCH可以映射到索引为 1的小区的物理上行控制信道
( hysical Uplink Control Channel, PUCCH ) 与物理上行共享信道(physical Uplink Shared Channel, PUSCH )。 MAC实体 1对应的 DL-SCH可以映射到索引 为 1的小区的物理下行控制信道( Physical Downlink Control Channel, PDCCH ) 与物理上行共享信道(Physical Downlink Shared Channel, PDSCH )。 (4)下行 物理层信道映射
MAC实体根据自身对应的 MAC层配置参数中的 MAC实体 /传输信道与小 区 /PHY实体的映射关系 , 将下行传输信道映射到下行物理层信道。 特别的, 一个 MAC实体可以映射到一个或多个小区 /物理实体。 例如, 将 MAC实体 1 (即, MAC-Entity-identity为 1 )映射到小区索引 1与小区索引 2的小区。 此时, MAC实体 1对应的 DL-SCH可以映射到索引为 1的小区的物理下行控制信道 ( Physical Downlink Control Channel, PDCCH )与物理上行共享信道( Physical Downlink Shared Channel, PDSCH )。
(5)基于逻辑信道优先级的上行调度
现有技术中, 由于所有的逻辑信道都映射到同一个 MAC 实体上, 那么 在调度时是对所有的逻辑信道进行优先级排序以及调度。 而本实施例中, 由 于逻辑信道映射到不同的 MAC实体上,对于每个 MAC实体其只对映射到自
身的逻辑信道进行优先级排序以及调度。 各 MAC 实体之间是独立执行的关 系。 也就是, 当收到上行授权(UL Grant )进行新传数据, UE将根据映射到 该发送上行授权小区 /物理实体对应 MAC实体的逻辑信道的优先级, 根据令 牌桶算法进行上行调度。
具体的, 针对每个 MAC实体, 当执行新传数据时, UE将根据映射到该 MAC实体的逻辑信道按照优先级, 采用令牌桶算法分配上行传输资源。令牌 桶算法是经典的数学算法,令牌桶算法具体内容包括: UE按照逻辑信道优先 级从高到低的顺序调度映射到该 MAC 实体的当前允许传输数据量的大小 ( Bj ) >0的逻辑信道数据; 当全部映射到该 MAC实体的逻辑信道的 Bj<=0, 但仍有上行资源剩余时, UE按照逻辑信道优先级从高到低的顺序调度映射到 该 MAC实体的逻辑信道数据。
本实施例通过为 UE配置多个 MAC实体,每个 MAC实体对应一组映射 关系, 那么就可以配置多组映射关系, 冲艮据该多组映射关系可以将不同的逻 辑信道映射到不同的传输信道和 /或物理层信道, 满足多流传输时的需求, 提 高 MAC层效率。
图 8为本发明多流传输的调度方法另一实施例的流程示意图, 本实施例 以配置一个 MAC实体但配置多组映射关系为例, 参见图 8, 包括:
步骤 81 :基站根据分流策略为 UE配置一个 MAC实体以及该 MAC实体 对应的 MAC层配置参数, 该 MAC层配置参数中包括一个映射关系列表, 该 映射关系列表中包括至少两组的映射关系参数, 每組映射关系参数至少包括 一组映射关系。
类似上一实施例, 根据分流策略, 假设要传输的数据可以分为第一数据 和第二数据, 第一数据在第一小区中传输, 第二数据在第二小区中传输, 那 么配置的映射关系可以包括: 将第一数据对应的逻辑信道映射到第一小区对 应的传输信道和 /或物理层信道上, 将第二数据对应的逻辑信道映射到第二小 区对应的传输信道和 /或物理层信道上。
上述的每组映射关系参数可以包括如下项中的至少一项:
(1) 映射关系标识( Channd-Mappmg-identity ), 用于标识一个映射关系, 方便映射关系增加 /删除 /修改。 该标识可以是 INTEGER类型。 例如,
Channel-Mapping-identity INTEGER(0..X),
(2)传输信道标识(Transport-Channel -identity ),用于标识一个传输信道。 该标识可以是 INTEGER类型。 例如,
Transport-Channel-identity INTEGER(0..X),
(3)传输信道与小区 /PHY实体的映射关系。 该映射关系表示 MAC传输信 道映射到该小区 /PHY实体的物理层信道。 例如:
Transport-channel-mapping- with-cell Cell-identity 还可以,
Transport-channel-mapping-with-PHY-entity PHY-entity-identity 其中 Cell-identity可以是任何一种小区标识, 例如物理小区标识( Physical Cell Identity, PCI )、 公共陆地移动网 ( Public Land Mobile Network, PLMN ) 范围内唯一的小区标识、 演进的 UMTS 陆地无线接入 ( Evolved-UMTS Terrestrial Radio Access , EUTRA ) 小区全局标识 ( Evolved Cell Global Identifier, ECGI )、 物理小区标识与栽波频点信息、 小区索引号等。 其中, 小 区索引号可以是当前已配置小区的索引 (cellindex )。 该索引信息可以把全部 配置小区进行索引。 PHY实体标识(PHY-entity-identity ) 为唯一标识 PHY实 体的标识, 该标识可以是 INTEGER类型。
(4)传输信道与逻辑信道 /RB映射关系。 该映射关系表示逻辑信道 /RB映 射到该 MAC实体。 例如:
Logical-and-transport-mappingList:: = SEQUENCE SIZE (L.maxLogicalC annelNum)) OF Logical-and-transport-mapping
Logical- and-transport-mapping : := SEQUENCE { logicalChannelldentity logicalChannelldentity
}
还可以用 RB标识( srb-Identity/drb-identity )代替逻辑信道标识来表示映 射关系。
Logical-and-RB-mappingList ::= SEQUENCE SIZE ( 1..maxRBNum)) OF Logical-and-RB-mapping
Logical-and-RB-mapping ::= SEQUENCE {
RB-identity RB-identity
}
特别的, 对于删除映射关系信息列表中可以只包括删除映射关系标识
( Channel-Mapping-identity )。
(4) MAC相关参数
映射关系中包含的 MAC参数可以是全部或部分 MAC层配置参数。例如, DRX机制参数、 HARQ最大重传次数(maxHARQ-Tx ) 、 SPS配置参数等。
步驟 82: 基站向 UE发送专用信令, 该专用信令中包含映射关系参数以 及对应的处理方式。
其中, 处理方式可以是增加、删除或者重配置一个或多个映射关系参数。 步驟 83: UE根据专用信令, 对相应的映射关系参数进行处理。
其中, 根据专用信令的指示, 可以增加、 删除或重配置映射关系参数。 处理后的映射关系参数就是专用信令中包含的映射关系参数。
步骤 84: UE根据每个处理后的映射关系参数, 执行 MAC功能。
其中, MAC实体执行的 MAC功能可以包括如下项中的至少一项: (1)上行传输信道映射
MAC 实 体根据传 输信 道与 逻辑信 道 /RB 的 映射 关 系 ( Logical-and-transport-mappingList ),将上行還辑信道映射到对应的上行传输 信道。 上行逻辑信道映射到上行传输信道的方式也可以参见图 6。
(2)下行传输信道映射
MAC 实 体根据传 输信 道与 逻辑信 道 /RB 的 映射 关 系 ( Logical-and-transport-mappingList ),将下行逻辑信道映射到对应的下行传输 信道。 下行逻辑信道映射到下行传输信道的方式也可以参见图 7。
(3)上行物理层信道映射
MAC实体根据传输信道与小区 /PHY实体的映射关系,将上行传输信道映 射到对应的小区 /物理实体的上行物理层信道。特别的, 一个 MAC实体可以映 射到一个或多个小区 /物理实体。
(4)下行物理层信道映射
MAC实体根据传输信道与小区 /PHY实体的映射关系,将下行传输信道映 射到对应的小区 /物理实体的下行物理层信道。特別的, 一个 MAC实体可以映 射到一个或多个小区 /物理实体。
(5)基于逻辑信道优先级的上行调度
现有技术中, 由于所有的逻辑信道都映射到同一个传输信道 /物理实体 / 小区上, 那么在调度时是对所有的逻辑信道进行优先级排序以及调度。
而本实施例中, 由于逻辑信道映射到不同的传输信道 /物理实体 /小区上, 对于每个传输信道 /物理实体 /小区其只对映射到自身的逻辑信道进行优先级 排序以及调度。
具体的, 针对每个传输信道 /物理实体 /小区, 当执行新传数据时, UE将 根据映射到该传输信道 /物理实体 /小区的逻辑信道按照优先级,采用令牌桶算 法分配上行传输资源。 即, UE按照逻辑信道优先级从高到低的顺序调度映射 到该传输信道 /物理实体 /小区的当前允许传输数据量的大小 (Bj ) >0 的逻辑 信道数据; 当全部映射到该传输信道 /物理实体 /小区的逻辑信道的 Bj<=0, 但 仍有上行资源剩余时, UE按照逻辑信道优先级从高到低的顺序调度映射到该 MAC实体的逻辑信道数据。
本实施例通过为 UE配置多组映射关系, 根据该多组映射关系可以将不 同的逻辑信道映射到不同的传输信道和 /或物理层信道, 满足多流传输时的需 求, 提高 MAC层效率。
