Description

提高用户设备上行覆盖能力的方法、 系统和装置 技术领域
本发明涉及通信技术领域, 特别涉及一种提高用户设备 ( UE )上行覆盖 能力的方法及装置。
背景技术
高速上行分组接入 ( HSUPA, high speed uplink packet access )是上行链路 方向 (从移动终端到无线接入网络的方向)针对分组业务的优化和演进。 HSUPA 利用自适应编码,物理层混合重传,基于基站(Node B )的快速调度和 2ms传 输时间间隔 ( TTI , Transmission Time Interval )短帧传输等机制, 实现了在最 高数据传输速率、 小区吞吐量以及延迟方面的增强。
在 UE总发射功率达到 UE最大发射功率时, 即可认为 UE处于功率受限 状态,此时,增强专用物理数据信道( E-DPDCH, E-DCH Dedicated Physical Data Channel )的功率增益因子会被降低到最小值, 该最小值可以是一个可配置值, 当 E-DPDCH功率增益因子被缩减到最小值后,会等比例的调整控制信道和数 据信道的功率。 由于 E-DPDCH功率增益因子的减小导致发送的数据包会在达 到混合自动重传请求(HARQ, Hybrid Automatic Repeat Request )最大重传次 数后解码失败。 当无线资源控制器(RNC, Radio Resource Controller )发现 UE处于功率受限时, 即便 Node B报告较高的 HARQ重传次数时, RNC也不 会提高目标信干比( SIR )值。
现有的提高 UE上行覆盖能力的方法是: UE向网络上报的相关信息中包 含 UE发射功率达到其最大允许发射功率信息时, RNC即判定该 UE上行发射 功率受限, 并发送信道重配消息给所述 UE; 所述 UE接收到信道重配置消息 后, 在确定的时刻执行该消息, 完成 2ms TTI到 10ms TTI的切换, 从而提高 UE上行覆盖能力。 发明内容

发明人通过分析,发现现有技术提供的方法虽然能够提高 UE的上行覆盖 能力, 但是, 由于需要由 RNC进行决策, 因而需要较长时间的时延才能完成 到 lOms TTI的切换, 因而容易造成数据丢失。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
参见图 1, 其是根据本发明实施例的提高 UE上行覆盖能力的流程图。 具 体包括:
步骤 101, Node B接收 UE上报的相关信息,该相关信息可以是 E-DPDCH 信道中调度信息( SI ) 内的表示 UE功率余量的信息;
步骤 102, 根据所述相关信息判定 UE上行发射功率受限后, 通知 UE采 用预设方案传输上行数据;
其中, 预设方案可以是更改 E-DPDCH信道编码的方式、 分时发送、 首次 盲传、 重传仅发送 E-DPDCH信道数据以及切换 TTI等等。
步骤 103,Node B采用与所述预设方案相对应的方式解码接收到的上行数 据。
应用本发明实施例, 由 Node B判断出 UE上行发射功率受限后 ,通知 UE 更改上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速 做出调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。 参见图 2,其是根据本发明实施例的另一种提 UE上行覆盖能力的流程图。 具体包括:
步骤 201 , UE上报表示自身功率余量的信息; 所述表示自身功率余量的 信息中包括上行发射功率受限的信息;
步骤 202, UE接收来自 Node B更改上行数据传输方式的通知, 该通知 中包括预设的方案;其中,更改上行数据传输方式的决定由所述 Node B作出; 其中, 预设方案可以是更改 E-DPDCH信道编码的方式、 分时发送、 首次 盲传、 重传仅发送 E-DPDCH信道数据以及切换 TTI等等。
步骤 203, UE采用所述通知中的预设方案传输上行数据。
应用本发明实施例, 在 UE接收到由 Node B作出决定的更改上行数据传 输方式的通知后,采用通知中所指出的预定方案传输上行数据, 缩短了决策时 延, 使得能够 UE在较短时延内迅速做出调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。
下面结合各种具体实现方式对本发明做详细说明。
参见图 3, 其是根据本发明实施例的一个具体实现的流程图。 本发明实施 例中采用更改 E-DPDCH信道编码的方式。
步骤 301, UE上报相关信息, 该相关信息可以是 E-DPDCH信道中调度 信息(SI ) 内表示自身功率余量的信息;
步骤 302, Node B接收 UE上报的相关信息, 根据所述相关信息判定所述 UE上行发射功率受限后, 通知 UE采用更改 E-DPDCH信道编码的方式传输 上行数据。
步骤 303, UE接收到上述通知后, 采用更改 E-DPDCH信道编码的方式 传输上行数据, 具体操作如下:
UE在一个 TTI内同时在 E-DPCCH信道和 E-DPDCH信道向网络侧上传 送上行数据; 其中, E-DPDCH信道内采用卷积编码方式; E-DPCCH信道承载 信令数据, 包括 UE在 E-DPDCH信道使用的传输格式指示信息、 新传重传数 据指示和 happy bit指示; E-DPDCH信道上承载的业务数据;
步骤 304, Node B根据 E-DPCCH信道承载的信令数据指示信息解调 E-DPDCH信道上承载的业务数据, 其中, Node B采用卷积编码方式解码接收 到的上行数据, 并给 UE发送反馈信息; 如果 Node B侧成功解码 E-DPDCH 的数据, 则反馈确认(ACK )给 UE; 如果 Node B侧解码失败, 则反馈非确 认(NACK )给 UE;
步骤 305, 如果 UE接收到来自 Node B的未成功接收信息, 则重传上行 数据 , 具体为重传此 TTI内的 E-DPCCH信道和 E-DPDCH信道的上行数据 , 直到接收到 Node B反馈的成功接收信息或者达到最大重传次数为止。
本实施例中, 由 Node B判断出 UE上行发射功率受限后 , 通知 UE更改 上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速做出 调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。 此外, 由于 UE将 E-DPDCH信道的编码方式由 Turbo编码更改为卷积编码, 而在传输块长度较 小时, 卷积编码比 Turbo编码能获得更好的编码增益, 从而更进一步增强了 UE的上行覆盖范围。 图 4是根据本发明实施例的另一个具体实现的流程图。本发明实施例中采 用分时发送的方式。
步骤 401, UE上报相关信息, 该相关信息可以是 E-DPDCH信道中调度 信息(SI ) 内表示自身功率余量的信息;
步骤 402, Node B接收 UE上报的相关信息, 根据所述相关信息判定所述 UE上行发射功率受限后,通知 UE采用分时发送的方式传输上行数据, 即 UE 分时发送 E-DPCCH和 E-DPDCH信道上的数据。
步骤 403 , UE接收到上述通知后, 采用分时发送的方式传输上行数据, 具体操作如下:
UE在一个 TTI内单独发送 E-DPCCH信道上的数据, E-DPCCH信道承载 信令数据, 包括 UE在 E-DPDCH信道使用的传输格式指示信息、 新传重传数 据指示和 happy bit指示;
UE在 E-DPCCH信道数据传送后下一个 TTI内单独发送 E-DPDCH信道 上的数据, E-DPDCH信道上承载的业务数据;所述 E-DPDCH信道上采用 Turbo 编码方式或卷积编码方式;
步骤 404, Node B根据两个 TTI上接收到的 E-DPCCH和 E-DPDCH上行 数据联合进行解码, 并给 UE发送反馈信息。
步骤 405, 如果 UE接收到来自 Node B未成功接收信息, 则重传上行数 据, 具体为在下一次对应的传输时刻重传 E-DPCCH信道上的数据, 并在 E-DPCCH信道重传之后的下一个 TTI内重传 E-DPDCH信道上的数据, 直到 接收到 Node B反馈的成功接收信息或者达到最大重传次数为止。例如,若 UE 在 HARQ进程 2发送 E-DPCCH信道上的数据,在进程 3发送 E-DPDCH信道 上的数据。 若随后 UE接收到来自 Node B对上述两个进程数据的未成功接收 信息, 则 UE在下一个环路时间 (RTT, Round Trip Time ) 的进程 2上重传 E-DPCCH信道上的数据, 在进程 3上重传 E-DPDCH信道上的数据, 以此来 保证 E-DPCCH信道和 E-DPDCH信道中的数据——对应。
本实施例中, 由 Node B判断出 UE上行发射功率受限后 , 通知 UE更改 上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速做出 调整, 因而在较短时间延迟下增加了 UE 的上行覆盖能力。 此外, 由于每个 制信道或数据信道的发送, 带来一定的增益, 从而更进一步增强了 UE的上行 覆盖范围。 图 5是根据本发明实施例的再一个具体实现的流程图。本发明实施例中采 用首次盲传的方式。
本实施例中, RNC预先在 NodeB和 UE内配置了增强专用传输信道传输
( E-TFC )子集, 该 E-TFC子集中包含不同传输块大小对应的索引号。
步骤 501, UE上报相关信息, 该相关信息可以是 E-DPDCH信道中 SI内 表示自身功率余量的信息;
步骤 502, Node B接收 UE上报的相关信息, 根据所述相关信息判定所述 UE上行发射功率受限后, 通知 UE采用首次盲传的方式传输上行数据。
步骤 503 , UE接收到上述通知后, 采用首次盲传的方式传输上行数据, 具体操作如下:
在进行新数据传输时, UE根据当前服务授权 ( Serving Grant )值允许的 数据量从已配置的 E-TFC子集中选择对应的传输块, 并在一个 TTI内发送已 选择的 E-DPDCH信道上的数据; E-DPDCH信道上采用 Turbo编码方式; 步骤 504,若 Node B接收到来自 UE的仅包括 E-DPDCH信道的上行数据 , 则将自身已配置的 E-TFC子集中所有传输块,依次与接收到的 E-DPDCH信道 数据中的传输块进行比较,使用与 E-DPDCH信道所采用的相匹配的传输块进 行解码, 即 Node B依据已配置的 E-TFC子集对接收到的 E-DPDCH信道数据 进行盲检测, 确定 UE所使用的传输块的大小并使用相应的传输块进行解码 , 并给 UE发送反馈信息; 若 Node B解码成功, 则向 UE返回 ACK; 若 Node B 解码失败, 则向 UE返回 NACK;
步骤 505, 如果 UE接收到来自 Node B未成功接收信息如 NACK, 则重 传传上行数据, 具体为在下一次对应的传输时刻重传 E-DPCCH 信道和 E-DPDCH信道的上行数据, E-DPCCH信道上携带 UE所选择的传输块的格式 指示信息。例如,若 UE收到来自 NACK信息后,在 HARQ进程 2发送 E-DPCCH 信道上的数据, 在进程 3发送 E-DPDCH信道上的数据。 若 UE随后又接收到 来自 Node B对上述两个进程数据的未成功接收信息, 则 UE在下一个环路时 间 (RTT, Round Trip Time ) 的进程 2上重传 E-DPCCH信道上的数据, 在进 程 3上重传 E-DPDCH信道上的数据,以此来保证 E-DPCCH信道和 E-DPDCH 信道中的数据——对应。
若 Node B接收到包含 E-DPCCH信道和 E-DPDCH信道的上行数据, 则 根据 E-DPCCH上所提供的传输格式指示解码 E-DPDCH信道的上行数据。
本实施例中, 由 Node B判断出 UE上行发射功率受限后 , 通知 UE更改 上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速做出 调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。 此外, 由于在进行 新数据传输时, UE从已配置的 E-TFC子集中选择预定义的传输块, 并在一个 TTI内只发送 E-DPDCH信道上的数据 , 并且不再需要传输 E-DPCCH信道数 据,由于每个 TTI内传递数据量的减少导致 UE在每个 TTI可将剩余全部发射 功率仅用于数据信道的发送, 增加了增益, 从而更进一步增强了 UE的上行覆 盖范围。 图 6是根据本发明实施例的又一个具体实现的流程图。本发明实施例中采 用重传仅发送 E-DPDCH信道数据的方式。
步骤 601, UE上报相关信息, 该相关信息可以是 E-DPDCH信道中 SI内 表示自身功率余量的信息。
步骤 602, Node B接收 UE上报的相关信息, 根据所述相关信息判定所述 UE上行发射功率受限后 , 通知 UE采用初传发送 E-DPCCH信道数据的方式 传输上行数据。
步骤 603, UE接收到上述通知后,采用初传发送 E-DPCCH信道数据的方 式传输上行数据, 具体操作如下:
在进行新数据传输时, UE 在一个 TTI 内同时在 E-DPCCH 信道和 E-DPDCH信道向网络侧上传送上行数据; 所述 E-DPDCH信道上采用 Turbo 编码方式或卷积编码方式;
步骤 604, Node B给 UE发送反馈信息。
步骤 605, 如果 UE未接收到来自 Node B的任何反馈信息, 则重传上行 数据 , 具体为重传此次传输的 E-DPCCH信道和 E-DPDCH信道的上行数据 , 直到接收到 Node B反馈的接收信息(成功 /失败)或者达到最大重传次数为止; 例如, 若 UE在 HARQ进程 2发送 E-DPCCH信道上的数据, 在进程 3发送 E-DPDCH信道上的数据。若随后 UE接收到来自 Node B对上述两个进程数据 的未成功接收信息, 则 UE在下一个环路时间 (RTT, Round Trip Time ) 的进 程 2上重传 E-DPCCH信道上的数据, 在进程 3上重传 E-DPDCH信道上的数 据 , 以此来保证 E-DPCCH信道和 E-DPDCH信道中的数据——对应。
如果 UE接收到来自 Node B的未成功接收信息, 则仅重传 E-DPDCH信 道的上行数据, 直到接收到 Node B反馈的成功接收信息或者达到最大重传次 数为止。
Node B首次接收到来自 UE的上行数据后,应用 E-DPCCH信道中指示的 格式指示对 E-DPDCH信道中的数据进行解码;
记录 E-DPCCH信道中指示的解码格式指示;
Node B再次接收到来自 UE的上行数据后, 应用已记录的解码格式指示, 对 E-DPDCH信道中的数据进行解码。
本实施例中 , 由 Node B判断出 UE上行发射功率受限后 , 通知 UE更改 上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速做出 调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。 此外, 由于在进行 新数据传输时, 只有首次在一个 TTI内同时传输 E-DPCCH信道和 E-DPDCH 信道的数据, 当首次传输失败且网络反馈未成功接收信息后,后续只需在一个 TTI内传输 E-DPDCH信道的数据, 由于在后续重传时每个 TTI内只传递的数 送, 增加了增益, 从而更进一步增强了 UE的上行覆盖范围。
图 7是根据本发明实施例的又一个具体实现的流程图。本发明实施例中采 用切换 TTI的方式。
步骤 701, UE上报相关信息, 该相关信息可以是 E-DPDCH信道中 SI内 表示自身功率余量的信息。
步骤 702, Node B根据 UE上报的相关信息判定所述 UE上行发射功率受 P艮后 , 通知 UE采用切换 TTI的方式传输上行数据。
步骤 703, UE接收到上述通知后, 采用切换 TTI的方式传输上行数据, 具体操作如下:
UE从当前长度的 TTK如 2mm TTI )切换为所述通知中所指定长度的 TTI, 如通知中指定 10mm TTI;
UE在指定长度的 TTK如 10mm TTI )内同时在 E-DPCCH信道和 E-DPDCH 信道向网络侧上传送上行数据; 其中, E-DPDCH信道上采用 Turbo编码方式; 步骤 704, Node B根据 E-DPCCH信道承载的信令数据指示信息解调
E-DPDCH信道上承载的业务数据, 其中, Node B采用 Turbo编码方式解码接 收到的上行数据, 并给 UE发送反馈信息; 如果 Node B侧成功解码 E-DPDCH 的数据, 则反馈 ACK给 UE; 如果 Node B侧解码失败, 则反馈 NACK给 UE; 步骤 705, 如果 UE接收到来自 Node B的未成功接收信息, 则重传上行 数据, 具体为在所述指定长度的 TTI (如 10mm TTI ) 内重传该 E-DPCCH信 道和 E-DPDCH信道的上行数据, 直到接收到 Node B反馈的成功接收信息或 者达到最大重传次数为止。
本实施例中, 由 Node B判断出 UE上行发射功率受限后 , 通知 UE更改 上行数据的传送方式, 缩短了决策时延, 使得能够 UE在较短时延内迅速做出 调整, 因而在较短时间延迟下增加了 UE的上行覆盖能力。 此外, 由于 TTI的 长度变长, 因而进一步增强了 UE的上行覆盖范围。
