Description

设备到设备通信的信息上报方法、 用户设备以及基站 技术领域
本发明涉及一种通信领域, 特别涉及一种设备到设备通信的信息上 报方法、 用户设备以及基站。 背景技术
设备到设备 (D2D, Device to Device) 通信指的是用户设备 (UE, User Equipment) 之间的直接通信, 可以有效提高无线系统的频谱效率以 及降低控制信令开销。 随着无线业务的不断扩展, 利用 D2D通信方式为 UE提供服务已经成为无线通信未来发展的必然趋势。
由于 UE的业务随着时间不断变化,而不同业务特性对 UE的功率消 耗有着很大影响。如果网络侧可以获取关于 UE的业务特性信息, 就可以 为 UE提供合适的配置, 从而降低 UE的功率消耗。 UE向网络侧提供关 于业务特性的辅助信息是一种非常有效的方法。
在 LTE Rel-11的标准化过程中, 针对 UE业务特性的多样性, 弓 1入 了 lbit的 UE辅助信息——功率偏好指示, 以实现 UE的节能。功率偏好 指示使得 UE可以根据当前业务特性来反应其是否需要节能。
但是, 发明人发现在现有方案中, 功率偏好指示只是针对 UE 的蜂 窝链路而提出, 如果 UE同时支持 D2D链路和蜂窝链路, 那么网络侧仅 根据 lbit的功率偏好指示,很难区分是 D2D链路还是蜂窝链路需要节能, 从而无法有效地为 UE提供合适的配置。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容

具体实施方式
参照附图, 通过下面的说明书, 本发明的前述以及其它特征将变得 明显。 在说明书和附图中, 具体公开了本发明的特定实施方式, 其表明 了其中可以采用本发明的原则的部分实施方式, 应了解的是, 本发明不 限于所描述的实施方式, 相反, 本发明包括落入所附权利要求的范围内 的全部修改、 变型以及等同物。
图 1是在蜂窝网络下的用户设备之间进行 D2D 通信的示意图, 如图 1所示, 小区用户除可以通过基站服务进行通信外, 它们之间还 可以通过 D2D 链路直接进行通信。
如图 1所示, 用户设备 102 ( UE1 ) 和配对用户设备 103 ( UE2) 由基站 lOK eNBl )服务, UE1与 UE2之间的数据传输无需通过 eNBl 以及核心网, 而控制信令可以仍由 eNBl发送。
为了对 UE提供合适的配置, UE需要向网络提供关于业务特性的辅 助信息——功率偏好指示, 以指示当前的通信链路是否需要节能。 由此, 网络侧可以获取关于 UE的业务特性信息,然后可以为 UE提供合适的配 置, 从而降低 UE的功率消耗。
以下以图 1 所示的场景为例对本发明进行详细说明, 但本发明不限 于此。 例如, 还可以具有多个 D2D通信链路, UE1可以同时与其他多个 用户设备进行 D2D通信。 实施例 1
本发明实施例提供一种 D2D通信的信息上报方法, 从 UE侧对本发 明进行说明。 图 2是本发明实施例的信息上报方法的一流程示意图, 如 图 2所示, 该信息上报方法包括:
歩骤 S201 , 用户设备向基站发送用于指示不同通信链路的功率偏好 的指示信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D 通信链路, 和 /或用户设备与基站之间的蜂窝通信链路。
在本实施例中, 其他用户设备可以是一个或者多个, 相应的, 通信 链路可以包括一个或者多个 D2D通信链路。即 D2D通信链路可以是一个, 也可以是多个。 指示信息对于不同的通信链路可以指示不同的功率偏好, 因此可以区分是 D2D通信链路还是蜂窝通信链路需要节能。 该指示信息 可以通过 RRC层或者 MAC层的专用消息传送。
在一个实施方式中, 指示信息可以至少包括功率偏好信息以及控制 信息, 该控制信息可以指示通信链路是 D2D通信链路或蜂窝通信链路。
在具体实施时, 功率偏好信息可以通过 lbit来实现, 可以用于指示 通信链路的功率偏好是 "低功耗"或是 "正常功耗"; 例如采用 "0"表 示正常功耗, 采用 " 1 "表示低功耗。
并且, 可以设定蜂窝通信链路的功率偏好指示, 将蜂窝链路标识包 含于控制信息中;可以设定 D2D通信链路的功率偏好指示,将 D2D链路 标识包含于控制信息中。 由此, 可以区分 D2D通信链路和蜂窝通信链路 的功率偏好。
其中, 指示蜂窝通信链路和 D2D通信链路的实施方式可以有两种: ( 1 ) lbit信息显式地标识是蜂窝通信链路还是 D2D通信链路, 例如采用 "0"表示蜂窝通信链路, 采用 " 1 "表示 D2D通信链路。 (2) 隐式地标 识是蜂窝通信链路还是 D2D通信链路,例如如果指示信息包含 D2D通信 链路标识, 则属于 D2D通信链路的功率偏好, 否则, 属于蜂窝通信链路 的功率偏好。
在另一个实施方式中, 指示信息至少可以包括功率偏好信息; 或者 该指示信息至少可以包括功率偏好信息和 D2D通信链路的标识信息。 并 且, 通过承载该指示信息的消息来指示通信链路是 D2D通信链路或蜂窝 通信链路。
更具体而言, 该消息可以是 D2D通信的专用消息, 例如 RRC层或 者 MAC层的消息。 因而该消息可以用来指示通信链路是 D2D通信链路 或蜂窝通信链路。
在具体实施时, 可以设定 D2D通信链路的功率偏好指示, 将 D2D 链路标识包含于控制信息中。 而对于蜂窝通信链路, 可以仍然采用现有 技术。
值得注意的是, 以上仅对用于指示不同通信链路的功率偏好的指示 信息进行了示意性说明, 但本发明不限于此, 还可以根据实际情况确定 具体的实施方式。
由上述实施例可知, 指示信息不仅可以指示具体的通信链路, 并且 还可以指示相应通信链路的功率偏好; 因此, 网络侧可以根据该指示信 息, 针对不同通信链路的业务特性提供相对应的配置, 从而更有效地控 制 UE的功率消耗。 实施例 2
在实施例 1的基础上, 本发明实施例还提供一种 D2D通信的信息上 报方法, 与实施例 1相同的内容不再赘述。 图 3是本发明实施例的信息上报方法的一流程示意图, 如图 3所示, 该信息上报方法包括:
歩骤 S301 , 用户设备判断是否已经发送过用于指示不同通信链路的 功率偏好的指示信息; 在判断没有发送时执行歩骤 S302, 在判断已经发 送过时执行歩骤 S303。
歩骤 S302, 用户设备向基站发送用于指示不同通信链路的功率偏好 的指示信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D 通信链路, 和 /或用户设备与基站之间的蜂窝通信链路。
在本实施例中, 只有在用户设备判断没有发送指示信息的情况下, 用户设备才向基站发送指示不同通信链路的功率偏好的指示信息。 在用 户设备判断已经发送指示信息 (即不是第一次发送) 的情况下, 用户设 备进一歩进行判断。
歩骤 S303 , 用户设备判断通信链路的功率偏好是否发生改变; 在判 断结果为发生改变的情况下执行歩骤 S304, 在判断结果没有发生改变的 情况下, 用户设备不再重复发送用于指示功率偏好的指示信息。
在本实施例中, 判断结果为发生改变可以指: 一个或多个通信链路 的功率偏好发生改变。 判断结果没有发生改变可以指: 所有通信链路的 功率偏好都没有改变。 但本发明不限于此, 可以根据实际情况确定具体 的实施方式。
歩骤 S304: 用户设备发送用于指示改变后功率偏好的指示信息。 在本实施例中, 例如, 用户设备对于某一 D2D通信链路, 已经向基 站发送功率偏好指示, 例如 "0"来指示采用正常功耗。 如果该功率偏好 不变, 则用户设备不再向该基站发送指示信息; 如果该功率偏好发生改 变, 则用户设备向该基站发送指示信息, 例如包含功率偏好指示 " 1 "来 指示采用低功耗。
由此, 在已经发送过指示信息的情况下, 当通信链路的功率偏好发 生改变时, 用户设备发送用于指示改变后功率偏好的指示信息, 可以实 现指示信息随着通信链路功率偏好的改变而动态更新, 从而使得用户设 备得到及时有效的配置。
当通信链路的功率偏好没有发生改变时, 可以不对用户设备的配置 进行调整, 因此, 用户设备无需再次发送相同的功率偏好的指示信息, 从而降低由于发送动作而产生的功耗。 但本发明不限于此, 基站也可能 根据其它的条件更改用户设备的配置。
在一个实施方式中, 当通信链路是 D2D通信链路时, 可以由同一条 D2D通信链路上的用户设备分别向基站上报指示信息。
例如, 参考图 1, 在用户设备 102和用户设备 103之间构成 D2D通 信链路的情况下, 可以由用户设备 102和用户设备 103分别向基站 101 发送指示信息。
在另一个实施方式中, 为了节省信息上报的功率消耗, 还可以由同 一条 D2D通信链路上的用户设备进行协商, 确定由一个用户设备进行发 送指示信息的动作。
例如, 参考图 1, 在用户设备 102和用户设备 103之间构成 D2D通 信链路的情况下, 可以由用户设备 102和用户设备 103进行协商, 从而 确定由用户设备 102或用户设备 103之一 (例如用户设备 102), 向基站 101发送指示信息。
由上述实施例可知, 指示信息不仅可以指示具体的通信链路, 并且 还可以指示相应通信链路的功率偏好, 因此, 网络侧可以根据该指示信 息, 针对不同通信链路的业务特性提供相对应的配置, 从而更有效地控 制 UE的功率消耗。 实施例 3
在实施例 1和 2的基础上, 本发明实施例还提供一种 D2D通信的信 息上报方法, 对用户设备从源基站向目标基站切换时的情况进行说明。 其中, 与实施例 1和 2相同的内容不再赘述。
图 4是本发明实施例的信息上报方法的一流程示意图, 如图 4所示, 该信息上报方法包括:
歩骤 S401 , 用户设备向基站发送用于指示不同通信链路的功率偏好 的指示信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D 通信链路, 和 /或用户设备与基站之间的蜂窝通信链路。
歩骤 S402, 用户设备从源基站向目标基站切换完成之后, 向目标基 站发送该指示信息。
在本实施例中, 用户设备可能会在不同基站之间发生切换。 如果在 收到切换命令之前的一段时间内, 用户设备向源基站发送过该指示信息, 则可以允许该用户设备向目标基站再次发送该指示信息。
例如, 在发生切换之前, 用户设备可能已经向源基站发送了用于指 示不同通信链路的功率偏好的指示信息, 但源基站并没能及时将此指示 信息发送给目标基站。 在切换完成之后, 用户设备可以再次向目标基站 发送该指示信息。
如实施例 2所述, 在通常情况下, 用户设备不会向基站发送相同的 功率偏好指示。 但在本实施例中, 与通常情况不同的是, 在发生切换的 情况下, 用户设备可以向目标基站发送相同的功率偏好指示。
由上述实施例可知, 通过用于指示不同通信链路的功率偏好的指示 信息, 网络侧可以根据该指示信息, 针对不同通信链路的业务特性提供 相对应的配置, 从而更有效地控制用户设备的功率消耗。 实施例 4
本发明实施例提供一种 D2D通信的信息上报方法, 从基站侧对本发 明进行说明。 其中, 与实施例 1和 2相同的内容不再赘述。
图 5是本发明实施例的信息上报方法的又一流程示意图, 如图 5所 示, 该信息上报方法包括:
歩骤 501 : 基站接收用于指示不同通信链路的功率偏好的指示信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D通信链路, 和 / 或用户设备与基站之间的蜂窝通信链路;
歩骤 502: 基站根据指示信息对用户设备进行配置。
在本实施例中, 用于指示不同通信链路的功率偏好的指示信息可以 由用户设备发送, 也可以由其他基站发送。
在一个实施方式中, 指示信息由用户设备发送, 该方法还包括: 该 基站接收其他用户设备发送的指示信息; 并且, 基站根据用户设备发送 的指示信息以及其他用户设备发送的指示信息, 对用户设备和其他用户 设备进行配置。 在具体实施时, 基站不仅可以接收某个用户设备发送的指示信息, 还可以接收与该用户设备构成一条 D2D通信链路的其他用户设备所发送 的指示信息。
例如, 参考图 1, 在用户设备 102和用户设备 103之间构成 D2D通 信链路的情况下, 基站 101可以接收用户设备 102所发送的指示信息和 用户设备 103所发送的指示信息, 并且基站根据用户设备 102所发送的 指示信息和用户设备 103所发送的指示信息, 对用户设备 102和用户设 备 103进行配置。
在另一个实施方式中, 指示信息由用户设备和其他用户设备的其中 之一发送, 该方法还包括: 基站根据该指示信息对用户设备和其他用户 设备进行配置。
在具体实施时, 同一 D2D链路中的用户设备之间可以进行功率偏好 的协商, 由其中一个用户设备发送指示信息, 在 D2D链路上传输协商信 令。 基站仅接收该用户设备发送的指示信息, 并且根据该指示信息对用 户设备和与之构成 D2D通信链路的其他用户设备进行配置。
例如, 参考图 1, 在用户设备 102和用户设备 103之间构成 D2D通 信链路的情况下, 用户设备 102和用户设备 103可以协商后由用户设备 102发送指示信息。 基站 101可以接收用户设备 102所发送的指示信息, 并且基站根据用户设备 102所发送的指示信息, 对用户设备 102和用户 设备 103进行配置。
在另一个实施方式中, 指示信息还可以由其他基站发送。 在该实施 方式中, 在用户设备从源基站向目标基站 (即歩骤 501 中的基站) 切换 时, 指示信息可以通过基站间的接口, 例如 X2接口或者其它的有线或者 无线接口, 由源基站向目标基站发送。
由此, 由源基站向目标基站发送指示信息, 该指示信息包括不同通 信链路的功率偏好, 其中通信链路是用户设备与其他用户设备之间的 D2D通信链路、 或者用户设备与基站之间的蜂窝通信链路。
由上述实施例可知, 通过用于指示不同通信链路的功率偏好的指示 信息, 网络侧可以根据该指示信息, 针对不同通信链路的业务特性提供 相对应的配置, 从而更有效地控制用户设备的功率消耗。 实施例 5
本发明实施例提供一种 D2D通信的信息上报方法, 从基站侧对本发 明进行说明。 其中, 与实施例 3相同的内容不再赘述。
图 6是本发明实施例的信息上报方法的又一流程示意图, 如图 6所 示, 该信息上报方法包括:
歩骤 S601 , 在用户设备从源基站向目标基站切换时, 源基站向目标 基站发送用于指示不同通信链路的功率偏好的指示信息; 所述通信链路 包括: 用户设备与其他用户设备之间的 D2D通信链路, 和 /或用户设备与 目标基站之间的蜂窝通信链路。
由此, 由源基站向当前的该基站发送指示信息, 从而可以向当前的 该基站指示不同通信链路的功率偏好, 以及通信链路是用户设备与其他 用户设备之间的 D2D通信链路、 或者用户设备与基站之间的蜂窝通信链 路。
由上述实施例可知, 通过用于指示不同通信链路的功率偏好的指示 信息, 网络侧可以根据该指示信息, 针对不同通信链路的业务特性提供 相对应的配置, 从而更有效地控制用户设备的功率消耗。 实施例 6
本发明实施例提供一种用户设备, 应用于 D2D通信。 本实施例对应 于实施例 1至 3所述的 D2D通信的信息上报方法, 与实施例 1至 3相同 的内容不再赘述。
图 7是本发明实施例的用户设备的一结构示意图。 如图 7所示, 用 户设备 700包括: 第一发送单元 701。用户设备 700的其他部分可以参考 现有技术。
其中, 第一发送单元 701 向基站发送用于指示不同通信链路的功率 偏好的指示信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D通信链路, 和 /或用户设备与基站之间的蜂窝通信链路。
在一个实施方式中, 指示信息可以包括功率偏好信息, 以及用于指 示通信链路是 D2D通信链路或蜂窝通信链路的控制信息。 在另一个实施方式中, 指示信息可以包括功率偏好信息; 或者还包 含用于指示设备到设备通信链路的标识信息; 并且通过承载指示信息的 消息来指示通信链路是 D2D通信链路或蜂窝通信链路。
具体地,该消息可以是 D2D通信的专用消息,例如 RRC层或者 MAC 层的消息。
由此, 通过该指示信息不仅可以指示具体的通信链路, 并且可以指 示相应通信链路的功率偏好。 因此, 网络侧可以根据该指示信息, 针对 不同通信链路的业务特性提供相对应的配置, 从而更有效地控制用户设 备的功率消耗。
图 8是本发明实施例的用户设备的又一结构示意图。 如图 8所示, 用户设备 800包括第一发送单元 701, 如上所述。
如图 8所示, 用户设备 800还可以包括: 第一判断单元 802。 该第一 判断单元 802用于判断是否已经发送指示信息; 并且, 第一发送单元 701 在第一判断单元 802 的判断结果为没有发送该指示信息时, 向基站发送 该指示信息。
如图 8所示, 用户设备 800还可以包括: 第二判断单元 803和第二 发送单元 804;
其中, 第二判断单元 803在第一判断单元 802的判断结果为已经发 送该指示信息时, 判断通信链路的功率偏好是否发生改变; 第二发送单 元 804在通信链路的功率偏好发生改变时, 发送用于指示改变后功率偏 好的指示信息, 该指示信息根据根据改变后的功率偏好而已经更新。
由此, 在已经发送过指示信息的情况下, 当通信链路的功率偏好发 生改变时, 用户设备发送用于指示改变后功率偏好的指示信息, 可以实 现指示信息随着通信链路功率偏好的改变而动态更新, 从而使得用户设 备得到及时有效的配置; 当通信链路的功率偏好没有发生改变时, 可以 不对用户设备的配置进行调整, 因此, 用户设备无需再次发送相同的功 率偏好的指示信息, 从而降低由于发送动作而产生的功耗。
如图 8所示, 用户设备 800还可以包括: 协商单元 805。 该协商单元 805与其他用户设备进行功率偏好的协商, 以确定由该用户设备和其他用 户设备中的其中之一发送指示信息。 在本实施例中,用户设备 800通过协商单元 805,可以与同一条 D2D 通信链路上的其他用户设备之间进行协商, 从而确定由用户设备 800进 行发送指示信息的动作, 由此, 可以降低发送动作产生的功率损耗。
在本实施例中, 用户设备 800还可以包括: 第三发送单元 806。 该第 三发送单元 806在用户设备从源基站向目标基站切换完成之后, 向目标 基站发送指示信息。
具体地, 如果在收到切换命令之前的一段时间内, 用户设备向源基 站发送过该指示信息, 第三发送单元被允许向目标基站再次发送相同的 或者不同的指示信息。
由上述实施例可知, 通过用于指示不同通信链路的功率偏好的指示 信息, 网络侧可以根据该指示信息, 针对不同通信链路的业务特性提供 相对应的配置, 从而更有效地控制用户设备的功率消耗。 实施例 7
本发明实施例提供一种基站, 应用于 D2D通信。 本实施例对应于实 施例 4所述的 D2D通信的信息上报方法, 与实施例 4相同的内容不再赘 述。
图 9是本发明实施例的基站的一结构示意图。如图 9所示,基站 900 包括: 接收单元 901和配置单元 902。基站 900的其他部分可以参考现有 技术。
其中, 接收单元 901 接收用于指示不同通信链路的功率偏好的指示 信息; 所述通信链路包括: 用户设备与其他用户设备之间的 D2D通信链 路, 和 /或用户设备与基站之间的蜂窝通信链路; 配置单元 902根据指示 信息对用户设备进行配置。
由此, 基站 900能够根据不同通信链路的功率偏好和通信链路的种 类 (例如, 通信链路是用户设备与其他用户设备之间的 D2D通信链路还 是用户设备与基站之间的蜂窝通信链路), 对相应的通信链路进行适当的 功率配置。
在一个实施方式中, 指示信息可以由一个用户设备发送, 该接受单 元 901 还可以接收其他用户设备发送的指示信息。 并且, 配置单元 902 还可以根据用户设备发送的指示信息以及其他用户设备发送的指示信 息, 对用户设备和其他用户设备进行配置。
在另一个实施方式中, 指示信息可以由用户设备和其他用户设备的 其中之一发送。 配置单元 902还可以根据指示信息对用户设备和其他用 户设备进行配置。
在另一个实施方式中, 在用户设备从源基站向该基站切换时, 该指 示信息可以由该源基站发送。
