Description
一种数据传输的方法及用户设备 技术领域
本申请涉及通信技术领域, 尤其涉及一种数据传输的方法及用户设备。 皆景技术
高级长期演进 ( Long Term Evolution -Advanced; LTE-A )是第三代伙伴 计划 ( 3rd Generation Partnership Project; 3GPP ) LTE系统的进一步演进和增 强系统。在 LTE-A系统中, 为了满足国际电信联盟对于第四代通信技术的峰值 数据速率要求引入了载波聚合 (CA ) 技术, 也称频谱聚合 ( Spectrum Aggregation )技术或者带宽扩展 ( Bandwidth Extension )技术。 载波聚合中, 两个或更多的成员载波( Component Carrier )的频谱被聚合在一起以得到更宽 的传输带宽, 各成员载波的频谱可以是相邻的连续频谱、 也可以是同一频带
LTE Rel-8/9协议版本中规 定, 用户设备(UE ) 只能接入其中一个成员载波进行数据收发, 而 LTE-A用 户设备根据其能力和业务需求可以同时接入多个成员载波进行数据收发。
为了支持动态调度及下行的多输入多输出( MIMO )传输及混合自动重传 等技术, UE需通过物理上行控制信道( PUCCH )及物理上行共享信道( PUSCH ) 向基站 eNB反馈多种上行控制信息 (Uplink Control Information; UCI ), 包括 信道状态信息( CSI )、混合自动重传确认信息( HARQ-ACK )和调度请求( SR ) 等, 其中混合自动重传确认信息也可筒单称为 ACK ( Acknowledgment; 确认 应答信息) /NACK ( Negative Acknowledgement; 否认应答信息)。
现有载波聚合系统都是同一个基站下的载波进行聚合, 或者有理想回传 (Backhaul)的宏小区和微小区下的载波聚合, 比如宏小区和微小区通过光纤连 接(此时微小区也可以是无线射频头), 这样多个载波间可以采用联合调度, 即基站在调度聚合载波中的一个载波时, 也知道另一个载波上的调度情况。 此时, UE向微基站反馈 HARQ-ACK时, 一般通过宏基站对应的上行主载波上
的 PUCCH将 HARQ-ACK发送至宏基站,再由宏基站将 HARQ-ACK转发至微基 站。 由于宏基站和微基站之间是理想回传的, 因此, 宏基站和微基站都可以 实时获得 UE反馈的 HARQ-ACK。
在后续演进的 LTE系统中,会引入基站间的载波聚合, 此时基站间是非理 想回传, 即基站间无法实时传送数据, 这样导致的结果是隶属于不同基站的 多个载波间的调度是独立进行的, 也就是说, 一个基站在调度聚合载波中的 一个载波时, 并不清楚另一个基站在另一个载波上的调度情况。 如图 1所示的 宏微小区耦合的场景下,部署在频率 fl的宏小区主要提供系统信息,无线链路 监测和移动性管理, 以保证业务的连续性; 部署在频率 f2的在宏小区的覆盖范 围内的多个微小区主要提供高数据速率业务的传输, 上述宏小区和微小区, 还有微小区之间都是非理想回传。
在上述基站间的 CA 统中, 由于多个下行载波的数据调度是每个基站独 立进行的, 比如在 fl的宏基站和在 f2的微基站独立调度, 例如各载波的 UCI也 分别反馈给各自的基站, 即 UE端会出现多个载波上都传输 UCI的情况, 例如, 会出现多个 PUCCH同时传输的情况,或出现多个带 UCI的 PUSCH传输的情况。 而且, 每个基站对 UE的上行发射功率调度也是独立进行的, 无法考虑其它基 站对该 UE的调度情况。 从 UE端来说, 当所有待传输上行信道和 /或信号的发 射功率之和超过 UE的最大发射功率时, 有的情况下可以执行功率缩减, 即将 向其中一个或多个基站发送的信号功率降低, 使得 UE的总发射功率满足不超 过 UE的最大发射功率的要求。
然而, 将向其中一个或多个基站发送的信号功率降低可能导致相应的信 号占用了传输的资源但却不能被基站正确解调, 造成系统整体性能的下降。 而且, 当 UE端发送到多个载波对应的多个基站的上行信号发送及时性要求都 较高的情况下, 例如如果 UE需要向两个基站同时反馈 HARQ-ACK信号时, 降 低其中一个或多个基站发送的信号功率的有可能导致该一个或多个基站向该 UE发送的下行数据的 HARQ-ACK长期无法正确接收而造成数据传输的无效
为了解决上述技术问题, 在上述基站间的 CA系统中, 可能存在一类能力 较低的 UE, 该类 UE的上行发送不能同时工作在多个基站对应的载波上, 每个 时刻只能工作在一个基站对应的上行载波上。该类 UE工作在上述基站间的 CA 系统中时, 可以通过限制两个基站对该 UE的调度, 或者修改 UE对基站下行数 据的 HARQ-ARQ反馈时序, 或者其他方法使得该种能力的用户设备也能在基 站间的 CA系统中进行工作。 同时, 对于这种类型的 UE不会出现 UE端发送到 多个载波对应的多个基站的上行信号总功率超过 UE的最大发射功率的现象。
然而, 本申请人在实现本申请实施例中的技术方案的过程中发现, 现有 技术中的方法虽然使得上行发送不能同时工作在多个基站对应的上行载波上 的 UE可以在基站间的 CA 统中工作, 且不会出现 UE端发送到多个载波对应 的多个基站的上行信号总功率超过 UE的最大发射功率。但是如果 UE具备同时 工作在多个基站对应的上行载波上的能力, 使用相同的方法会造成 UE的能力 利用不充分以及可能的下行数据调度受限的问题。

下面结合附图对本申请优选的实施方式进行详细说明。
实施例一
本实施例提供一种数据传输的方法, 请参考图 2所示, 为本实施例中的 数据传输的方法的流程图, 该方法包括:
步骤 101: 用户设备 UE向第一部分或所有的网络侧设备发送辅助调度信 息,指示第一部分或所有的网络侧设备根据辅助调度信息确定 UE的上行发射 状态,并根据 UE的上行发射状态确定能够触发 UE发射数据的网络侧设备为 所有的网络侧设备或者为第二部分的网络侧设备;
步骤 102: UE根据第二部分或所有的网络侧设备发送的调度信息发射数 据。
其中, 在本实施例中, 上行发射状态是能够同时在所有的网络侧设备对 应的上行载波上传输上行数据的第一上行发射状态, 或是同时在第二部分的 网络侧设备对应的上行载波上传输上行数据的第二上行发射状态, 网络侧设 备是能够与 UE进行通信的网络侧设备。
在一实施例中, 关于当上行发射状态为第二上行发射状态时, 同时在第 二部分的网络侧设备对应的上行载波上传输上行数据, 这里的第二部分的网 络侧设备可以是距离 UE较近的设备, 因为较近, 所以 UE到这些网络侧设备 的总功率不会超过 UE的最大发射功率。 当然, 在其他实施例中, 这里的第二 部分的网络侧设备还可以是其他的网络侧设备,例如距离 UE较远的设备, 只 要 UE的实际发射功率不超过最大发射功率即可。
图 2中所示的方法是从用户设备侧进行描述的, 请再参考图 3所示, 为 本实施例中的数据传输的方法的在网络侧设备侧, 例如基站、 基站控制器、 中继的方法流程图, 请参考图 3所示, 该方法包括:
步骤 201 : 网络侧设备接收用户设备 UE发送的辅助调度信息;
步骤 202: 网络侧设备根据辅助调度信息确定 UE的上行发射状态; 步骤 203: 网络侧设备根据确定的上行发射状态, 确定能够触发 UE发射 数据的网络侧设备为所有的网络侧设备或者为部分的网络侧设备。
便于描述, 这里特别说明一下, 在图 3中, 网络侧设备侧的流程描述中, "部分的网络侧设备" 与图 2 中用户设备侧的流程描述中 "第二部分的网络 侧设备" 为相同的概念, 以下统一称为 "第二部分的网络侧设备"。
以下将结合图 2和图 3对本实施例中的数据传输的方法进行详细描述。
其中, 请先参考图 2所示, 用户设备(UE )先执行步骤 101 , 即 UE向 第一部分或所有的网络侧设备发送辅助调度信息, 以使第一部分或所有的网 络侧设备根据辅助调度信息确定 UE的上行发射状态,并根据 UE的上行发射 状态确定能够触发 UE发射数据的网络侧设备为所有的网络侧设备或者为第 二部分的网络侧设备。 而对应网络侧设备, 就会执行步骤 201 , 即接收 UE发 送的辅助调度信息, 然后网络侧设备就执行步骤 202, 即网络侧设备根据 UE 发送的辅助调度信息确定 UE的上行发射状态, 然后执行步骤 203 , 网络侧设 备根据确定的上行发射状态,确定能够触发 UE发射数据的网络侧设备为所有 的网络侧设备或者为第二部分的网络侧设备; 然后所有的网络侧设备或者为 第二部分的网络侧设备可以发送调度信息给 UE, 以触发 UE发射数据, 即对 UE进行调度。 最后, UE则执行步骤 102, 根据第二部分或所有的网络侧设 备发送的调度信息发射数据。
首先举例说明辅助调度信息可以是什么样的信息, 在一实施例中, 辅助 调度信息具体为: 用于指示 UE建议的上行发射状态的指示信息、 或者 UE需 要做上行发射状态的转移的指示信息, 还可以是功率信息。
(1) 用于指示 UE建议的上行发射状态的指示信息。 UE可以预先通过以 下步骤确定建议的上行发射状态: UE确定在每个网络侧设备的要发送的上行 信道的发射功率,根据确定的所有发射功率之和以及 UE的最大发射功率,确 定建议的上行发射状态。 在本实施例中, 上行信道包括 PUCCH, PUSCH, PRACH等, 但是这些信道不一定是同时要发送的, 比如在第 n个子帧 UE对 这个网络侧设备发 PUCCH但没有 PUSCH, 第 n+1子帧对这个网络侧设备可 能发射 PUCCH和 PUSCH, 对于每个网络侧设备都是类似的情况, 所以在本 实施例中, UE确定在每个网络侧设备的要发送的上行信道的发射功率, 例如 在某个时刻, UE在每个网络侧设备的要发送的上行信道的功率之和, 即有可 能是到第一个网络侧设备的 PUCCH+到第二个网络侧设备的 PUSCH+到第三 个网络侧设备的 PUCCH+ , ……的功率之和。
在实际运用中, UE确定在每个网络侧设备的要发送的上行信道的发射功
率具体有且不限于以下两种实施方式。
第一实施方式, 是一个粗略的估算, UE根据收到的至少两个网络侧设备 的下行参考信号, 确定路径损耗, 根据确定的路径损耗确定在每个网络侧设 备的要发送的上行信道的发射功率。 例如, UE通过测量至少两个基站的下行 参考信号获得了基站到 UE之间的路径传输损耗。那么 UE的上行发送需要至 少去掉路径损耗后到达基站时可以达到基站对该信道信息的正确解调门限, 如此便可粗略获得 UE在每个网络侧设备的每个上行信道的发射功率之和为 第二实施方式, 是一个较精确的估算, UE根据收到的至少两个网络侧设 备的上行发射功率调整命令和 UE在每个网络侧设备的要发送的上行信道的 功率调整方案, 确定在每个网络侧设备的要发送的上行信道的发射功率。
在一实施例中,当计算的结果是 UE在每个网络侧设备的要发送的上行信 道的功率之和超过 UE的最大发射功率,那么就确定建议的上行发射状态为第 二上行发射状态,
当计算的结果是 UE在每个网络侧设备的要发送的上行信道的功率之和 未超过 UE的最大发射功率,那么就确定建议的上行发射状态为第一上行发射 状态。
在另一实施例中,当计算的结果是 UE在每个网络侧设备的要发送的上行 信道的功率之和在一个预定的时间范围内超过 UE 的最大发射功率的次数小 于预设的第一门限值时, 确定建议的上行发射状态为第一上行发射状态; 当计算的结果是 UE在每个网络侧设备的要发送的上行信道的功率之和 超过 UE的最大发射功率,那么就确定建议的上行发射状态为第二上行发射状 态,或者, 当计算的结果是 UE在每个网络侧设备的要发送的上行信道的功率 之和在一个预定的时间范围内超过 UE 的最大发射功率的次数大于预设的第 二门限值时, 确定建议的上行发射状态为第二上行发射状态。
进一步地, 当 UE确定建议的上行发射状态为第二上行发射状态时,还确 定第二部分的网络侧设备是哪些网络侧设备。 在实际运用中, 第二部分网络
侧设备可以分为几组。 例如, 和 UE通信的网络侧设备为 Celll、 Cell2、 Cell3、 Cell4 , UE确定建议的上行发射状态为第二上行发射状态, UE可以同时在 Celll 和 Cell3的载波上传输上行数据或者同时在 Cell2和 Cell4的载波上传输数据。
Celll和 Cell3对应的基站为第一组网络侧设备, Cell2和 Cell4对应的基站为 第二组网络侧设备。
然后基于上述建议的上行发射状态生成辅助调度信息。 如果所建议的上 行发射状态为第二上行发射状态, 所述的辅助调度信息还可以进一步包括第 二部分的网络侧设备的标识信息, 并且第二部分的网络侧设备的标识信息中 包括至少一组网络侧设备的标识信息。
(2) UE需要做上行发射状态的转移的指示信息。 如上述辅助调度信息是 用于指示 UE建议的上行发射状态的信息的方法所述, 只是在本实施例中, UE可以不给出建议的上行发射状态, 而是只是根据计算结果生成 UE是否需 要做上行发射状态的转移的指示信息。
(3)功率信息。 功率信息包括下列信息中的部分或全部: UE从所有的网络 侧设备接收的下行参考信号接收功率;所有的网络侧设备到 UE的路径传输损 耗值; 根据比较所有发射功率之和与最大发射功率得到的功率余量。 可以是 UE主动发送给网络侧设备, 例如周期性发送, 还可以是网络侧设备发送触发 指令给 UE, 然后 UE发送功率信息给特定的网络侧设备。
由此可以看出, 可以在 UE的总发射功率超过 UE的最大发射功率时, 通 过调整 UE的上行发射状态来解决, 例如在第一上行发射状态下, 如果 UE的 总发射功率超过 UE的最大发射功率, 那么就可以调整为第二上行发射状态, 而不是降低向一个或多个网络侧设备发送的信号功率; 同时, 在第二上行发 射状态下, 如果 UE的总发射功率和 UE的最大发射功率之间有足够的余量, 那么就可以调整为第一上行发射状态或者调整第二上行发射状态中部分网络 侧设备的集合,避免了部分网络侧设备对 UE的数据调度传输无效性问题,提 高了系统的整体性能。
其次, 举例说明用户设备 ( UE ) 向第一部分或所有的网络侧设备发送辅
助调度信息,以使第一部分或所有的网络侧设备根据辅助调度信息确定 UE的 上行发射状态, 并根据 UE的上行发射状态, 确定能够触发 UE发射数据的网 络侧设备为所有的网络侧设备或者为第二部分的网络侧设备,以及对 UE进行 调度的实施方式。 在一实施例中, 针对不同的场景和情况, 具体有很多种实 施方式, 以下进行举例说明:
其中, 请先参考图 2所示, 用户设备(UE )先执行步骤 101 , 即 UE向 第一部分或所有的网络侧设备发送辅助调度信息, 以使第一部分或所有的网 络侧设备根据辅助调度信息确定 UE的上行发射状态,并根据 UE的上行发射 状态确定能够触发 UE发射数据的网络侧设备为所有的网络侧设备或者为第 二部分的网络侧设备。 而对应网络侧设备, 就会执行步骤 201 , 即接收 UE发 送的辅助调度信息, 然后执行步骤 202 , 即网络侧设备根据 UE发送的辅助调 度信息确定 UE的上行发射状态, 再然后执行步骤 203 , 网络侧设备根据确定 的上行发射状态,确定能够触发 UE发射数据的网络侧设备为所有的网络侧设 备或者为第二部分的网络侧设备; 然后所有的网络侧设备或者为第二部分的 网络侧设备可以发送调度信息给 UE, 以触发 UE发射数据, 即对 UE进行调 度。 最后, UE则执行步骤 102, 根据第二部分或所有的网络侧设备发送的调 度信息发射数据。
在第一种场景下, 第一部分的网络侧设备能够控制其他的网络侧设备的 调度。 例如宏基站( Macro eNodeB )和微基站( Pico eNodeB )布网的场景下, 微基站上可以本身没有数据包, 而在微基站下传输的数据包是宏基站发送给 微基站的, 并且宏基站可以控制微基站对具体数据包的物理层调度。 假设当 前和 UE通信的所有的网络测设备包括宏基站下的 Cell A, 第一微基站下的 Cell B和第二微基站下的 Cell C。 此时可能有两种情况:
( 1 ) 第一种情况: UE处于第一上行发射状态
当前 UE处于第一上行发射状态, 即 UE能够同时在所有的网络侧设备对 应的上行载波上传输上行数据, 即 Cell A、 Cell B和 Cell C的上行载波上传输 数据。此时,如果 UE决定在相同时刻只可以在部分基站的上行载波发射数据
而不适合同时在所有基站的上行载波上发射数据。 那么 UE就只向 Macro基 站发送辅助调度信息即可, 那么 Macro基站即为第一部分的网络侧设备。 如 上所述,该辅助调度信息的内容可以是指示该 UE建议上行发射状态为第二上 行发射状态。进一步地,该辅助调度信息的内容还可以包括该 UE可以在 CellA 的上行载波发射数据或者同时在 CellB和 CellC的上行载波发射数据,如此便 于网络侧设备确定第二部分的网络侧设备具体为哪些网络侧设备。
宏基站接收到该辅助调度信息之后,可以确定该 UE的上行发射状态为第 二上行发射状态,并确定能够触发 UE发射数据的网络侧设备为第二部分的网 络侧设备。 并且决定对该 UE的调度方式, 对该 UE的调度方式可以为保证 UE不需要同时向所有网络侧设备的上行载波发射上行数据的方式对该 UE进 只有部分网络侧设备能够进行调度, 或者只有其中第二部分网络侧设备对 UE 做数据调度等方式, 即固定的部分网络侧设备。 需要说明的是, 所列举的网 络侧设备对 UE的数据调度方式只是举例说明, 实际的调度方式不限于此。进 一步地, 可以根据接收的辅助调度信息中的第二部分的网络侧设备的标识信 调度信息中的第二部分的网络侧设备的标识信息表示的意思为 "该 UE可以在 CellA的上行载波发射数据或者同时在 CellB和 CellC的上行载波发射数据", 那么对该 UE的调度方式可以为 CellA或者 CellB+CellC以时分的方式对 UE 做数据调度、 或者只有 CellA对该 UE做数据调度、 或者只有 CellB+CellC对 该 UE做数据调度。宏基站可以将确定的该 UE的数据调度方式通知其它相关 基站, 例如第一微基站和第二微基站, 以便第一微基站和第二微基站用该种 方式对 UE进行数据调度 , UE则根据各网络侧设备发送的调度信息发射数据。
可选地, 在该场景的这种情况下, UE也可以向宏基站、 第一微基站和第 二微基站都发送辅助调度信息,或者 UE可以向宏基站发送辅助调度信息后由 宏基站将此辅助调度信息转发给第一微基站和第二微基站。 如上所述, 该辅 助调度信息的内容可以是指示该 UE建议上行发射状态为第二上行发射状态。
进一步地,该辅助调度信息的内容还可以包括该 UE可以在 CellA的上行载波 发射数据或者同时在 CellB和 CellC的上行载波发射数据。 宏基站、 第一微基 站和第二微基站将以此 UE建议的上行发射状态作为 UE的上行发射状态。并 按照该 UE的上行发射状态对 UE做数据调度, 对 UE做数据调度方式如上所 述, 这里不再重复。 UE则根据各网络侧设备发送的调度信息发射数据。
可选地, 宏基站、 第一微基站和第二微基站也可以通过协商确定 UE的 上行发送状态以及对 UE的调度方式。并按照协商的结果对该 UE做数据调度, UE则根据各网络侧设备发送的调度信息发射数据。
( 2 ) 第二种情况: UE处于第二上行发射状态
有两种可能性:
a) 第一种可能性: 当前 UE处于第二上行发射状态, 即 UE只能够同时 在部分网络侧设备对应的上行载波上传输上行数据,当前网络侧设备对 UE的 调度方式可以保证该 UE 不需要同时向所有网络侧设备的上行载波发射上行 数据的方式对该 UE进行数据调度。 此时, 如果 UE判断其上行发射功率和最 大发射功率之间的余量足够,如 UE上行发射功率和未超过最大发射功率或者 UE上行发射功率在一个预定的时间范围内超过 UE的最大发射功率的次数小 于预设的第一门限值, 则可以认为自己可以同时在所有的网络侧设备对应的 上行载波上传输上行数据。那么 UE就向宏基站发送辅助调度信息。该辅助调 度信息的内容可以是指示该 UE建议上行发射状态为第一上行发射状态。
宏基站接收到该辅助调度信息之后,可以确定该 UE的上行发射状态为第 一上行发射状态,并确定能够触发 UE发射数据的网络侧设备为所有的网络侧 设备。 并且决定对该 UE的调度方式, 对该 UE的调度方式可以为所有网络侧 设备对该 UE进行数据调度没有限制。例如,所有网络侧设备可以在任何时刻 对 UE做数据调度。宏基站可以将确定的该 UE的数据调度方式通知其它相关 基站, 例如第一微基站和第二微基站, 以便第一微基站和第二微基站用该种 方式对 UE进行数据调度 , UE则根据各网络侧设备发送的调度信息发射数据。
可选地, 在该场景这种情况的这种可能性下, UE也可以向宏基站、 第一
微基站和第二微基站都发送辅助调度信息,或者 UE可以向宏基站发送辅助调 度信息后由宏基站将此辅助调度信息转发给第一微基站和第二微基站。 如上 所述, 该辅助调度信息的内容可以是该辅助调度信息的内容可以是指示该 UE 建议上行发射状态为第一上行发射状态。 宏基站、 第一微基站和第二微基站 将以此 UE建议的上行发射状态作为 UE的上行发射状态。 并按照该 UE的上 行发射状态对 UE做数据调度, 对 UE做数据调度方式如上所述, 这里不再重 复。 UE则根据各网络侧设备发送的调度信息发射数据。
可选地,宏基站、第一微基站和第二微基站也可以通过协商确定 UE的上 行发送状态以及对 UE的调度方式。 并按照协商的结果对该 UE做数据调度, UE则根据各网络侧设备发送的调度信息发射数据。
b)第二种可能性: 当前 UE处于第二上行发射状态, 即 UE只能够同时在 部分网络侧设备对应的上行载波上传输上行数据,当前网络侧设备对 UE的调 度方式可以保证该 UE 不需要同时向所有网络侧设备的上行载波发射上行数 据的方式对该 UE进行数据调度。 此时, 如果 UE根据其上行发射功率和最大 发射功率之间的比较判断认为自己可以同时在 CellB和 CellC对应的上行载波 上传输上行数据, 但不能同时在 CellA、 CellB和 CellC对应的上行载波上传 输上行数据。那么 UE向宏基站发送辅助调度信息,该辅助调度信息的内容可 以是指示该 UE 建议上行发射状态为第二上行发射状态并且该 UE 可以在 CellA的上行载波发射数据或者同时在 CellB和 CellC的上行载波发射数据。
宏基站接收到该辅助调度信息之后,可以确定该 UE的上行发射状态为第 二上行发射状态,并确定能够触发 UE发射数据的网络侧设备为第二部分的网 络侧设备。 并且决定对该 UE的调度方式。 对该 UE的调度方式可以为 CellA 或者 CellB+CellC以时分的方式对 UE做数据调度、 或者只有 CellA对该 UE 做数据调度、 或者 CellB+CellC对该 UE做数据调度。 宏基站可以将确定的该 UE的数据调度方式通知其它相关基站, 例如第一微基站和第二微基站, 以便 第一微基站和第二微基站用该种方式对 UE进行数据调度。
可选地, 在该场景这种情况的这种可能性下, UE也可以向宏基站、 第一
微基站和第二微基站都发送辅助调度信息,或者 UE可以向宏基站发送辅助调 度信息后由宏基站将此辅助调度信息转发给第一微基站和第二微基站。 如上 所述,该辅助调度信息的内容可以是指示指示该 UE建议上行发射状态为第二 上行发射状态并且该 UE可以在 CellA的上行载波发射数据或者同时在 CellB 和 CellC的上行载波发射数据。 宏基站、 第一微基站和第二微基站将以此 UE 建议的上行发射状态作为 UE的上行发射状态。并按照该 UE的上行发射状态 对 UE做数据调度, 对 UE做数据调度方式如上所述, 这里不再重复, UE则 根据各网络侧设备发送的调度信息发射数据。
可选地,宏基站、第一微基站和第二微基站也可以通过协商确定 UE的上 行发送状态以及对 UE的调度方式。 并按照协商的结果对该 UE做数据调度, UE则根据各网络侧设备发送的调度信息发射数据。
在第二种场景下, 每个网络侧设备主控自己的调度。 例如宏基站(Macro eNodeB )和微基站( Pico eNodeB )布网的场景下, 微基站自己有自己要发送 的数据包, 也可以自主决定对数据包的物理层调度而不完全依赖于宏基站的 指示。 假设当前和 UE通信的所有的网络测设备包括宏基站下的 Cell A, 第一 微基站下的 Cell B和第二微基站下的 Cell C。 此时有两种情况:
( 1 ) 第一种情况: UE处于第一上行发射状态
当前 UE处于第一上行发射状态, 即 UE能够同时在所有的网络侧设备对 应的上行载波上传输上行数据, 即 Cell A、 Cell B和 Cell C的上行载波上传输 数据。此时,如果 UE决定在相同时刻只可以在部分基站的上行载波放射数据 而不适合同时在所有基站的上行载波上发射数据。那么 UE向宏基站、第一微 基站和第二微基站都发送辅助调度信息。 如上所述, 该辅助调度信息的内容 可以是指示该 UE建议上行发射状态为第二上行发射状态。进一步地,该辅助 调度信息的内容还可以包括该 UE可以在 CellA的上行载波发射数据或者同时 在 CellB和 CellC的上行载波发射数据。
宏基站、 第一微基站和第二微基站将以此 UE建议的上行发射状态作为 UE的上行发射状态。 并确定能够触发 UE发射数据的网络侧设备为第二部分
的网络侧设备。 并且决定对该 UE的调度方式, 对该 UE的调度方式可以为保 证 UE不需要同时向所有网络侧设备的上行载波发射上行数据的方式对该 UE 进行数据调度, 即同时只有第二部分的网络侧设备可以进行数据调度。 例如, 侧设备对 UE做数据调度等方式, 即固定的第二部分的网络侧设备。需要说明 的是,所列举的网络侧设备对 UE的数据调度方式只是举例说明, 实际的调度 方式不限于此。 进一步地, 可以根据接收的辅助调度信息中的第二部分的网 络侧设备的标识信息确定第二部分的网络侧设备具体是哪些网络侧设备以及 对该 UE的具体的调度方式。例如如果辅助调度信息中的第二部分的网络侧设 备的标识信息为 "该 UE可以在 CellA的上行载波发射数据或者同时在 CellB 和 CellC的上行载波发射数据", 则根据该信息对该 UE调度。 对该 UE的调 度方式可以为 CellA或者 CellB+CellC以时分的方式对 UE做数据调度、 或者 只有 CellA对该 UE做数据调度、 或者 CellB+CellC对该 UE做数据调度, UE 则根据各网络侧设备的调度发射数据。
可选地,宏基站、第一微基站和第二微基站接收到 UE发送的辅助调度信 照协商的结果对该 UE做数据调度 , UE则根据各网络侧设备的调度发射数据。
( 2 ) 第二种情况: UE处于第二上行发射状态
有两种可能性:
a) 第一种可能性: 当前 UE处于第二上行发射状态, 即 UE只能够同时 在部分网络侧设备对应的上行载波上传输上行数据,当前网络侧设备对 UE的 调度方式可以保证该 UE 不需要同时向所有网络侧设备的上行载波发射上行 数据的方式对该 UE进行数据调度。 此时, 如果 UE判断其上行发射功率和最 大发射功率之间的余量足够, 则可以认为自己可以同时在所有的网络侧设备 对应的上行载波上传输上行数据。那么 UE向宏基站、第一微基站和第二微基 站都发送辅助调度信息。该辅助调度信息的内容可以是指示该 UE建议上行发 射状态为第一上行发射状态。
宏基站、第一微基站和第二微基站接收到 UE发送的辅助调度信息后, 可 以确定该 UE的上行发射状态为第一上行发射状态,并确定能够触发 UE发射 数据的网络侧设备为所有的网络侧设备。 并且决定对该 UE的调度方式,对该 UE的调度方式可以为所有网络侧设备对该 UE进行数据调度没有限制。例如, 的调度发射数据。
可选地,宏基站、第一微基站和第二微基站接收到 UE发送的辅助调度信 照协商的结果对该 UE做数据调度 , UE则根据各网络侧设备的调度发射数据。
b)第二种可能性: 当前 UE处于第二上行发射状态, 即 UE只能够同时在 部分网络侧设备对应的上行载波上传输上行数据,当前网络侧设备对 UE的调 度方式可以保证该 UE 不需要同时向所有网络侧设备的上行载波发射上行数 据的方式对该 UE进行数据调度。 此时, 如果 UE根据其上行发射功率和最大 发射功率之间的比较判断认为自己可以同时 CellB和 CellC对应的上行载波上 传输上行数据, 但不能同时在 CellA、 CellB和 CellC对应的上行载波上传输 上行数据。该辅助调度信息的内容可以是指示该 UE建议上行发射状态为第二 上行发射状态并且该 UE可以在 CellA的上行载波发射数据或者同时在 CellB 和 CellC的上行载波发射数据。
宏基站、第一微基站和第二微基站接收到 UE发送的辅助调度信息后, 可 以确定该 UE的上行发射状态为第二上行发射状态,并确定能够触发 UE发射 数据的网络侧设备为第二部分的网络侧设备。 并且决定对该 UE的调度方式, 对该 UE的调度方式可以为 CellA或者 CellB+CellC以时分的方式对 UE做数 据调度、 或者只有 CellA对该 UE做数据调度、 或者 CellB+CellC对该 UE做 数据调度, UE则根据各网络侧设备的调度发射数据。
可选地,宏基站、第一微基站和第二微基站接收到 UE发送的辅助调度信 照协商的结果对该 UE做数据调度 , UE则根据各网络侧设备的调度发射数据。
需要说明的是, 以上实施例只是对上述各种场景各种情况的各种可能性 网络侧设备和用户设备可能的实施方式, 而上述各种场景各种情况的各种可 能性网络侧设备和用户设备可使用的实施方式不限于此。 在具体实施过程中, 当辅助调度信息为用于指示 UE建议的上行发射状态或者 UE需要做上行发射 状态的转移的指示信息时, 网络侧设备根据 UE发送的指示信息确定 UE的上 行发射状态,例如按照 UE建议的上行发射状态确定,或者根据指示信息要求 UE上报功率信息, 然后网络侧设备再根据功率信息确定。
当辅助调度信息为功率信息时,网络侧设备根据 UE发送的功率信息确定 UE的上行发射状态, 例如网络侧设备可以根据功率信息确定 UE在每个网络 侧设备的要发送的上行信道的发射功率之和是否会超过 UE的最大发射功率, 或者要发送的上行信道的发射功率之和在一个预定的时间范围内是否超过 UE 的最大发射功率的次数小于预设的第一门限值时或者大于预设的第二门 限值, 然后确定 UE的上行发射状态, 当 UE在每个网络侧设备的要发送的上 行信道的功率之和超过 UE的最大发射功率,那么就确定 UE的上行发射状态 为第二上行发射状态。进一步地, 网络侧可以根据 UE在每个网络侧设备的要 发送的上行信道的发射功率确定第二上行发射状态中第二部分的网络侧设备 是哪个或哪几个网络侧设备。当 UE在每个网络侧设备的要发送的上行信道的 功率之和未超过 UE的最大发射功率, 或者, 如果 UE当前的上行发射状态是 第二发射状态,当计算的结果是 UE在每个网络侧设备的要发送的上行信道的 功率之和在一个预定的时间范围内超过 UE 的最大发射功率的次数小于预设 的第一门限值时, 那么就确定 UE 的上行发射状态为第一上行发射状态。 当 UE在每个网络侧设备的要发送的上行信道的功率之和超过 UE的最大发射功 率, 或者, 如果 UE 当前的上行发射状态是第一发射状态, 当计算的结果是 UE在每个网络侧设备的要发送的上行信道的功率之和在一个预定的时间范 围内超过 UE的最大发射功率的次数大于预设的第二门限值时,确定建议的上 行发射状态为第二上行发射状态。
如上实施例所述,当 UE发送的辅助调度信息只发给相关的第一部分基站
并由相关的第一部分基站确定 UE的上行发送状态以及并确定能够触发 UE发 射数据的网络侧设备为第二部分的网络侧设备或所有的网络侧设备, 以及对 UE的调度方式时, 可以由第一部分基站将确定的 UE的上行发送状态以及对 UE的调度方式传给其他基站, 以便其它基站确定 UE的上行发送状态并根据 确定的对 UE的调度方式对 UE调度。
进一步地, 当 UE发送的辅助调度信息只能发给相关的第一部分基站, 另 外一些基站有可能不知道该 UE的辅助调度信息,可以由接收到辅助调度信息 的基站将 UE的辅助调度信息传给其他基站。然后所有基站协商确定 UE的上 行发送状态以及对 UE的调度方式。
相应的, UE执行步骤 102时, 即根据第二部分或所有的网络侧设备的调 度信息发射数据。
在进一步的实施例中,在步骤 202之后, 网络侧设备还通知 UE进行上行 发射状态切换和 /或确定的对 UE的调度方式, 因为上行发射状态的切换, 有 可能影响 UE在接收或者发射数据以后的一些行为,例如 UE在获知上行发射 状态切换之后, 可能影响 UE给基站发送 ACK/NACK的一些机制。
举例来说,如果 UE处于第一上行发射状态, 当前需要将上行发射状态转 为第二发射状态。 UE处于第二发射状态时, 所有网络侧设备仍然可以同时为 该 UE调度下行数据, 而对这些网络侧设备发射的下行数据的 ACK/NACK反 馈信息, UE可以通过捆绑 (HARQ-ACK反馈信息做逻辑 and运算)或者将 一个上行时间单元分为多个时间组, 各个时间组内的资源分时对个网络侧设 备反馈 HARQ-ACK信息。 例如, LTE系统中, 有两个基站, 宏基站和微基站 和 UE通信, 当 UE处于第二发射状态时, 宏基站和微基站同时调度为该 UE 发送下行数据, UE可以将 LTE系统中 UE的一个上行子帧的两个时隙分别用 于向宏基站和微基站反馈 HARQ-ACK信息。 在这些情况下, UE需要获知网 络侧设备确定的 UE的上行发射状态。
由以上描述可以看出,在本申请实施例中, 首先因为 UE既可以工作在第 一上行发射状态, 即在所有的网络侧设备对应的上行载波上传输上行数据,
又可以工作在第二上行发射状态, 即在部分的网络侧设备对应的上行载波上 传输上行数据, 所以可以在 UE的总发射功率超过 UE的最大发射功率时, 通 过调整 UE的上行发射状态来解决, 例如在第一上行发射状态下, 如果 UE的 总发射功率超过 UE的最大发射功率, 那么就可以调整为第二上行发射状态, 而不是降低向一个或多个网络侧设备发送的信号功率; 同时, 在第二上行发 射状态下, 如果 UE的总发射功率和 UE的最大发射功率之间有足够的余量, 那么就可以调整为第一上行发射状态或者调整第二上行发射状态中部分网络 侧设备的集合,避免了部分网络侧设备对 UE的数据调度传输无效性问题,提 高了系统的整体性能; 其次, UE向网络侧设备发送辅助调度信息, 而网络侧 设备能够基于该辅助调度信息确定 UE的上行发射状态,并根据 UE的上行发 射状态对 UE进行调度, 所以能够根据 UE的状况及时调整 UE的上行发射状 态, 所以能够保证系统的整体性能。
接下来请参考图 4所示, 为本申请实施例中数据传输的方法的一个具体 的例子, 其中, 网络侧设备以基站为例, 该方法包括:
步骤 301 : UE确定辅助调度信息。 辅助调度信息可以是用于指示 UE建 议的上行发射状态的信息、 UE需要做上行发射状态的转移的指示信息、 或者 功率信息;
步骤 302: UE发送辅助调度信息给第一部分或全部基站;
步骤 303: 基站基于辅助调度信息确定 UE的上行发射状态, 并根据上行 发射状态确定能够触发 UE发射数据的基站为所有的基站或者为第二部分的 基站和对 UE的调度方式。可以是第一部分基站确定 UE的上行发射状态和对 UE的调度方式, 也可以是全部基站协商确定 UE的上行发射状态和对 UE的 调度方式;
步骤 304: 基站通知 UE确定的上行发射状态和 /或对 UE的调度方式; 对 应的, UE就执行步骤 305;
步骤 305: UE进行上行发射状态切换; 例如切换为第二上行发射状态; 步骤 306: 基站根据确定的 UE的上行发射状态和对 UE的调度方式, 对
UE进行调度;
步骤 307: 基站将确定的 UE的上行发射状态和 /或对 UE的调度方式, 发 给其他基站, 以使其他基站根据确定的上行发射状态对 UE进行调度; 例如转 发给其他相关的基站, 那么其他相关的基站也可以对 UE进行调度;
步骤 308: UE根据第二部分或所有的基站发送的调度信息发射数据。 其中, 步骤 304和步骤 307的执行顺序可以根据实际情况进行变化, 可 以同时执行, 也可以不是同时执行。
