Description

触发非周期的测量参考信号的方法、 基站和用户设备 技术领域
本发明涉及一种通信领域， 特别涉及一种触发非周期的测量参考信 号的方法、 基站和用户设备。 背景技术
测量参考信号 （SRS: Sounding Reference Symbol) 是一种用户设备 (UE: User Equipment) 与基站 （eNB: e-NodeB) 之间用来测量上行链 路无线信道状态信息 (CSI: Channel State Information)的信号。
在长期演进***（LTE: Long-term Evolution)***中， 用户设备 UE 按照基站 eNB指示的发送带宽、 频域起始位置、 序列循环移位、 周期和 子帧偏置等参数， 定时在发送子帧的最后一个数据符号上发送上行测量 参考信号 SRS。基站 eNB根据接收到的测量参考信号 SRS判断该用户设 备 UE上行的信道状态信息 CSI,并根据得到的信道状态信息 CSI进行频 域选择调度、 闭环功率控制等操作。
在增强的长期演进*** LTE-A (Long-term Evolution-Advanced )中， 为了改善测量参考信号 SRS资源的利用率， 提高资源调度的灵活性， 还 引入了非周期的测量参考信号 SRS机制。 此处为了描述方便， 将周期地 发送的测量参考信号 SRS称为周期的测量参考信号 SRS, 将非周期地发 送的测量参考信号 SRS称为非周期的测量参考信号 SRS。 目前， 通过基 站发送的用于上行传输的下行控制信令 （DCI : Downlink Control Information)进行触发， 即通过 DCI format 0和 DCI format 4通知用户设 备是否发送非周期的测量参考信号 SRS。 其中， 基站 eNB可通过无线资 源控制 （RRC: Radio Resource Control) 层信令为用户设备 UE配置发送 非周期 SRS所使用的资源集合。
在 LTE和 LTE-A***中， 在以下两种情况下， 为了进行上行数据传 输， 用户设备 UE首先需要进行随机接入， 1 ) 用户设备 UE的上行时间 提前计时器 （TAT ： Time Advance Timer) 超时后； 2) 在用户设备 UE 在物理上行控制信道（PUCCH: Physical Uplink Control Channel)上向基 站发送调度请求 （SR: Scheduling Request) 到达最大传输次数后。 随机 接入成功后，基站 eNB会为用户设备 UE调度上行资源来发送上行数据。
为了能有效地调度用户设备 UE进行上行数据传输所需要的上行物 理资源， 基站 eNB需要首先获得用户设备 UE的上行信道状态信息 CSI。 目前， 为了获得用户设备 UE的上行信道状态信息 CSI, 基站只能通过用 户设备 UE发送的周期的 SRS来做信道估计。 然而， 在上述两种情况发 生后， 用户设备 UE会释放掉周期的 SRS资源。 因此， 目前可行的方法 是：基站 eNB需要通过无线资源控制 RRC层信令为该用户设备 UE配置 发送周期的测量参考信号 SRS的资源。 然后， 该用户设备 UE并非立即 发送周期的测量参考信号 SRS, 而是等待发送时刻的到来， 在预先配置 的发送时刻向基站 eNB发送该周期的测量参考信号 SRS;基站 eNB在接 收到该周期的测量参考信号 SRS后， 根据该测量参考信号 SRS来获得上 行的信道状态信息 CSI, 从而根据该信道状态信息 CSI进行资源调度。
发明人在实现本发明的过程中发现现有技术的缺陷在于： 由于基站 首先需要通过无线资源控制 RRC层信令为用户设备 UE配置发送周期的 SRS的资源， 同时用户设备 UE需要等待发送时刻到来时向基站 eNB发 送测量参考信号 SRS, 因此， 基站 eNB获得上行信道状态信息 CSI的时 延较大， 导致基站 eNB无法在有上行数据需要发送的情况下快速对用户 设备 UE进行调度； 此外， 在 LTE-A***中， 在上述情况下， 没有有效 地利用非周期的测量参考信号 SRS来获得信道状态信息的方法。

具体实施方式
下面结合附图对本发明的各种实施方式进行说明。 这些实施方式只 是示例性的， 不是对本发明的限制。 为了使本领域的技术人员能够容易 地理解本发明的原理和实施方式， 本发明的实施方式以增强的长期演进
(LTE-A: Long Term Evaluation Advanced) ***中的非周期的测量参考 信号 SRS的触发为例进行介绍， 但是应该理解， 本发明不限于该***， 可用于任何涉及触发非周期的测量参考信号 SRS的***。
图 1是本发明实施例 1的触发非周期的测量参考信号的方法流程图。 如图 1所示， 该方法包括：
歩骤 101， 若用户设备 UE失同歩或者用户设备 UE向基站发送调度 请求 SR失败， 则该用户设备 UE不释放基站为该用户设备 UE配置的发 送非周期的测量参考信号 SRS所使用的资源；
歩骤 102， 该用户设备 UE执行随机接入过程；
歩骤 103， 若随机接入成功， 则该用户设备 UE根据该基站下发的指 示用户设备 UE发送非周期的测量参考信号 SRS的指示信息，在未释放的 该基站为该用户设备 UE配置的发送非周期的测量参考信号 SRS所使用 的资源上发送非周期的测量参考信号 SRS。
在本实施例中， 在歩骤 101 中， 当用户设备 UE的用于维持上行同 歩的时间提前计时器 TAT超时， 可确定该用户设备 UE失同歩； 在用户 设备 UE保持上行同歩且需要传输上行数据时，向基站发送调度请求请求 传输该上行数据的上行资源，若发送该调度请求 SR的次数超过预设值还 未获得基站为其分配的上行资源，则确定该用户设备 UE发送调度请求失败。
在歩骤 101 中， 当发生上述情况时， 用户设备 UE不释放发送非周 期的 SRS所使用的资源，以便在接收到基站发送的指示发送非周期的 SRS 指示信息时， 利用该资源传输非周期的 SRS , 使得该基站快速地获得用 户设备 UE的上行信道状态信息 CSI, 从而快速地调度用户设备 UE的上 行数据的传输。
在本实施例中， 当歩骤 101 中用户设备 UE失同歩， 并且当用户设 备 UE需要向基站传输上行数据时，需要执行随机接入过程以获得上行同 歩以及通知基站其有传输上行数据的需求； 当歩骤 101 中， 保持上行同 歩的用户设备 UE向基站发送调度请求 SR失败， 需要发送随机接入过程 以通知基站其有传输上行数据的需求。
这样， 当在歩骤 101中出现上述情况时， 在歩骤 102中， 用户设备 UE执行随机接入过程， 其中该随机接入过程可以是非竞争的随机接入也 可以是竞争的随机接入， 过程与现有技术类似， 以下参照附图 2A 和图 2B对基于竞争和非竞争的随机接入过程进行简要说明。
图 2A是本发明实施例 1中基于竞争的随机接入过程流程图。在基于 竞争的随机接入过程中， 由用户设备 UE发起或者由基站触发随机接入， 此处以用户设备 UE发起随机接入为例进行说明。
如图 2A所示， 包括：
歩骤 201， 用户设备 UE向该基站发送随机接入前导 Preamble。
歩骤 202， 该基站接收该随机接入前导 Preamble, 向该用户设备 UE 返回随机接入响应 （RAR: Random Access Response ) 消息；
其中， 该 RAR消息中可包括用于上行同歩的时间调整信息、 初始的 上行资源分配 （用户发送随后的 Msg3 )、 以及临时无线网络临时标识 C-RNTI等信息。
歩骤 203， 该用户设备 UE接收到该 RAR消息后， 获得上行的时间同 歩和上行资源； 但是， 由于此时并不能确定该 RAR消息是发送给该用户 设备 UE还是发送给其他用户设备， 因此， 该用户设备 UE向该基站发送 Msg3消息， 以解决上述随机接入冲突； 并且该用户设备 UE同时开启竞争 消除定时器 (mac-Contention Resolution Timer);
其中， 在该 Msg3消息中携带用户设备 UE的标识信息， 以区分不同 的用户设备。
歩骤 204， 该用户设备 UE在竞争消除定时器未超时的情况下， 接收 到基站返回的冲突解决 （Contention Resolution) 消息， 则该用户设备 UE可确定此次的随机接入成功； 否则随机接入过程失败。
图 2B是本发明实施例 1中基于非竞争的随机接入过程流程图。其中， 非竞争随机接入过程由基站触发。 基站预先通知用户设备 UE使用特定无 冲突的随机接入前导序列和资源来进行接入， 这样就可以避免可能发生 的冲突， 减少随机接入的时间延迟。 由于不需要解决冲突的问题， 因此， 非竞争的随机接入过程相对简单。 如图 2B所示， 包括：
歩骤 20Γ ， 基站通知用户设备 UE使用特定的无冲突的随机接入前 导序列和资源。
歩骤 202 ' ，该用户设备 UE根据该基站通知的特定的随机接入前导 序列向该基站发送特定的无冲突的随机接入前导 Pr eamb 1 e。
歩骤 202， 该基站接收该随机接入前导 Preamble, 可根据该前导标 识确定该用户设备 UE发起的非竞争随机接入， 向该用户设备 UE返回随 机接入响应 (RAR: Random Access Response) 消息；
其中， 该 RAR消息中可包括用于上行同歩的时间调整信息、 为用户 设备 UE 分配上行数据传输所需要的资源、 以及临时无线网络临时标识
C-RNTI等信息。
在本实施例中， 在歩骤 102中用户设备 UE执行随机接入成功时， 在歩骤 103中，在该用户设备 UE接收到基站下发的指示用户设备 UE发 送非周期的测量参考信号 SRS 的指示信息时， 在未释放的资源上发送非 周期的测量参考信号 SRS。 这样， 可使基站快速获得用户设备 UE的上行 信道状态信息 CSI, 从而快速地调度用户设备 UE的上行数据的传输。
在本实施例中，在需要用户设备 UE发送非周期的测量参考信号 SRS 时， 基站可利用物理下行控制信息 （DCI: Downlink Control Information) 发送指示用户设备 UE发送非周期的 SRS的指示信息， 并且该物理下行 控制信息 DCI 通过物理下行控制信道 （PDCCH ： Physical Downlink Control Channel)进行传输。 此外， 物理下行控制信令 DCI在 PDCCH上 的承载格式称为下行控制信息格式 （DCI format ： Downlink Control Information format)。 在 LTE***中， DCI format共分为 DCI format 0， format 1 , formatlA, formatlB , formatlC , format ID, format2 , format2A, format3， format3A等 10种。 在 LTE-A***中， 除了包含上述 10种 DCI format， 还包括 DCI format 4。
在本实施例中，基站可以通过 DCI format 0或 DCI format 4来触发用 户设备 UE发送非周期的 SRS。
在通过 DCI format 0来触发用户设备 UE发送非周期的 SRS时， 在
DCI format 0中加入一个新的 bit。 基站可以通过该新加入的 bit来触发用 户设备 UE发送非周期的 SRS。例如， 在该 bit为 1时， 指示用户设备 UE 发送非周期的 SRS。 发送该非周期的 SRS需要的资源集合预先通过高层 信令， 即无线资源控制 （RRC: Radio Resource Control) 协议进行配置。 并且只有一个资源集合可供选择。 在该 bit为 0时， 指示用户设备 UE不 发送非周期的 SRS。

其中， 基站下发指示信息可由 DCI format 0或 DIC format 4或 DCI format 1A承载， 但不限于此， 还可由其他任何信息承载， 如实施例 1 所述， 此处不再赘述。
由上述实施例可知， 用户设备 UE在时间提前计时器 TAT超时或者 在 PUCCH上发送调度请求 SR失败 （发送调度请求的次数达到最大值） 后， 不释放基站为其配置的发送非周期的测量参考信号 SRS的资源， 并 且在其随机接入成功， 且接收到基站发送的指示其发送非周期的 SRS的 指示信息后， 可根据该指示信息并利用未释放的资源向基站发送该非周 期的测量参考信号 SRS ,使得该基站快速地获得用户设备 UE的上行信道 状态信息 CSI, 从而快速地调度用户设备 UE的上行数据的传输。
图 4是本发明实施例 3的触发非周期的测量参考信号的方法流程图。 如图 4所示， 该方法包括：
歩骤 401， 若用户设备 UE失同歩或者用户设备 UE向基站发送调度 请求 SR失败， 则该用户设备 UE不释放基站为该用户设备 UE配置的发 送非周期的测量参考信号 SRS所使用的资源；
歩骤 402， 该用户设备 UE执行随机接入过程； 其中， 该用户设备 UE 可以执行竞争或非竞争的随机接入过程，其过程如实施例 1的图 2A和 2B 所述，该用户设备 UE自发或在基站触发的情况下向基站发送随机接入前导; 歩骤 403， 该用户设备 UE根据随机接入过程中该基站返回的随机接 入响应消息中包含的指示用户设备 UE是否发送非周期的测量参考信号的 指示信息的类型确定是否发送非周期的测量参考信号 SRS; 歩骤 404， 若该用户设备 UE确定发送非周期的测量参考信号 SRS, 则该用户设备 UE在未释放的该基站为该用户设备 UE配置的发送非周期 的测量参考信号 SRS所使用的资源上发送非周期的测量参考信号 SRS。
在本实施例中， 在当歩骤 401 中用户设备 UE失同歩， 并且当用户 设备 UE需要向基站传输上行数据时，需要执行随机接入过程以获得上行 同歩以及通知基站其有传输上行数据的需求； 当歩骤 401 中， 保持上行 同歩的用户设备 UE向基站发送调度请求 SR失败， 需要发送随机接入过 程以通知基站其有传输上行数据的需求。 这样， 当在歩骤 401 中出现上 述情况时， 在歩骤 402中， 用户设备 UE执行随机接入过程， 该用户设备 UE向基站发送随机接入前导。 当基站接收到该随机接入前导后， 可生成 并返回包含指示该用户设备 UE发送非周期的 SRS的指示信息的 RAR消 息， 过程在下述说明； 其中， 若基站确定需要该用户设备 UE发送非周期 的测量参考信号， 则该指示信息用于指示用户设备 UE 发送非周期的 SRS, 否则该指示信息用于指示用户设备 UE不发送非周期的 SRS。
这样， 在歩骤 403中， 该用户设备 UE接收到该 RAR消息时， 可读 取该指示信息， 并根据该指示信息的类型来确定是否发送非周期的 SRS, 具体的确定过程如下参照图 5和图 6进行说明。
在本实施例中， 该 RAR消息中包含的指示信息由该随机接入响应消 息中的预留比特 R来承载； 或者由新增的比特来承载， 在这种情况下， 可在上行带宽授予 （UL Grant ) 域中新增比特 bit 来承载该指示信息， 但在这种情况下保持该 RAR消息中总的 bit数不变。
其中， 比特数可为 1个， 例如， 若该 lbit对应的状态为 " 1 " 时， 表示指示用户设备 UE发送非周期的 SRS, 若该 lbit对应的状态为 "0" 时， 表示指示用户设备 UE不发送非周期的 SRS。 但不限于上述 bit , 还 可采用其他 bi t来承载该指示信息。
由上述可知， 由于采用不同的承载方式， 该 RAR消息可对应不同的 格式， 不同格式的 RAR消息对应不同的处理方式。 其中，
该 RAR消息的格式可由基站预先配置并通知用户设备 UE, 以使用户 设备 UE在接收到该 RAR消息时， 根据配置的格式进行相应的处理；
或者， 由基站预先根据随机接入类型来配置相应的 RAR消息的格式， 并通知该用户设备 UE， 以使该用户设备 UE在接收到该 RAR消息时， 根据 配置的与随机接入类型对应的格式作相应的处理。
在这种情况中， 考虑到与现有技术兼容的问题， 基站可仅配置非竞 争的随机接入过程对应的随机接入响应消息的格式并通知用户设备 UE , 以使用户设备 UE在非竞争随机接入的情况下采用预先配置的与非竞争的 随机接入过程对应的随机接入响应消息的格式对接收到的 RAR消息进行 处理； 对于竞争的随机接入过程对应的随机接入响应消息的格式可与用 户设备 UE约定采用默认的方式， 即原有的格式。
在本实施例中， 该方法还包括以下准备过程： 接收该基站为该用户 设备 UE配置的发送非周期的测量参考信号 SRS所使用的资源信息。
或者还可包括：
该用户设备 UE接收基站为该用户设备 UE配置该随机接入响应消息 的格式； 或者接收该基站为该用户设备 UE配置的与随机接入过程的类型 对应的随机接入响应消息的格式。
图 5是本发明实施例 3中歩骤 403的实现流程图之一。其中，该 RAR 消息的格式由基站预先配置并通知用户设备 UE， 以使该用户设备 UE在接 收到该 RAR消息时， 根据配置的格式进行相应的处理。
如图 5所示， 包括如下歩骤：
歩骤 501，该用户设备 UE接收该基站根据该用户设备 UE发送的随机 接入前导所返回的 RAR消息；
其中， 该 RAR消息包含指示用户设备 UE是否发送非周期的测量参考 信号 SRS 的指示信息， 其中， 无论是竞争的随机接入过程还是非竞争的 随机接入过程， 基站在生成该 RAR消息时， 该 RAR消息的格式均采用基 站预先配置的格式；
例如， 该 RAR消息的格式可为该指示信息由该随机接入响应消息中 的预留比特 R或者新增的比特来承载的格式；
对于竞争的随机接入过程， 在该基站在生成 RAR消息时， 将该 RAR 消息中的指示信息设置为 " 0 "; 对于非竞争的随机接入过程， 在该基站 生成 RAR消息时， 若基站确定需要用户设备 UE发送非周期的 SRS时， 将 指示信息设置为 " 1 "， 否则将指示信息设置为 " 0 "。 歩骤 502，根据预先配置的 RAR消息的格式对该 RAR消息进行相应的 处理， 以获得该 RAR消息中包含的指示信息；
其中， 对该 RAR消息进行处理是指对该 RAR消息进行解码。
歩骤 503，判断该指示信息的类型是否为发送非周期的测量参考信号 SRS的指示信息； 若判断结果为是， 则执行歩骤 504， 否则执行歩骤 505 ; 其中， 例如， 若该指示信息为 " 1 "， 则表示发送非周期的 SRS; 若该 指示信息为 " 0 "， 则表示不发送非周期的 SRS;
但上述指示信息仅为本发明实施例， 此外也可采用其他任何标识来 歩骤 504，在歩骤 503中判断结果为是， 即该指示信息的类型为发送 非周期的测量参考信号 SRS的指示信息， 则该用户设备 UE可确定发送非 周期的测量参考信号 SRS。
歩骤 505， 在歩骤 503中， 判断结果为否， 即该指示信息的类型为不 发送非周期的测量参考信号 SRS的指示信息， 则该用户设备 UE确定不发 送非周期的 SRS。
由上述实施例可知， 在用户侧， 无论用户设备 UE执行非竞争的随机 接入还是竞争的随机接入过程， 基站根据预先配置的 RAR 的格式生成相 应的 RAR消息， 并且该用户设备 UE可根据预先配置的 RAR消息的格式对 接收到的 RAR消息进行处理， 以获得该 RAR消息中的指示信息； 其中， 若该指示信息的类型为 " 1 "， 则可确定发送非周期的 SRS; 若该指示信息 的类型为 " 0 "， 则可确定不发送非周期的 SRS。 在这种情况下， 该用户设 备 UE对接收到的 RAR消息进行处理时，不需要区分其随机接入过程的类型。
图 6是本发明实施例 3中歩骤 403的实现流程图之二。其中，该 RAR 消息的格式由基站预先配置并通知用户设备 UE, 并且该 RAR消息的格式 与随机接入类型相对应， 以使该用户设备 UE在接收到该 RAR消息时， 根 据与随机接入类型相应的 RAR消息的格式对接收到的 RAR消息进行相应 的处理。 具体地， 该基站可仅配置非竞争的随机接入过程对应的随机接 入响应消息的格式并通知用户设备 UE; 对于竞争的随机接入过程对应的 随机接入响应消息的格式可与用户设备 UE约定采用默认的方式。
如图 6所示， 包括如下歩骤： 歩骤 601，该用户设备 UE接收该基站根据该用户设备 UE发送的随机 接入前导所返回的 RAR消息；
其中， 该 RAR消息包含指示用户设备 UE是否发送非周期的测量参考 信号 SRS的指示信息；
该 RAR消息的格式可采用基站预先配置的格式， 并且该 RAR消息的 格式与随机接入类型相对应； 例如， 竞争的随机接入过程对应默认的 RAR 消息的原来的格式； 非竞争的随机接入过程对应基站配置的包括指示信 息的 RAR消息的格式， 例如， 该格式可为使用 RAR消息中的预留比特 R 来承载指示信息的格式； 或者该格式可为使用 RAR消息中的新增的比特 来承载指示信息的格式；
这样， 该基站在接收到该用户设备 UE发送的随机接入前导， 生成该 RAR消息时，可根据预先配置的与该随机接入类型对应的随机接入响应消 息的格式来生成该 RAR消息； 其中， 对于竞争的随机接入过程， 采用默 认的原有格式， 其中不包含指示信息， 或者将原有格式中的预留比特 R 设置为 "0 "， 指示用户设备 UE不发送非周期的 SRS; 对于非竞争的随机 接入过程， 采用配置的与非竞争的随机接入过程对应的随机接入响应消 息的格式， 其中， 若基站确定需要用户设备 UE发送非周期的 SRS时， 将 指示信息设置为 " 1 "， 否则将指示信息设置为 " 0 "。
歩骤 602， 该用户设备 UE判断随机接入类型为非竞争的随机接入过 程还是竞争的随机接入过程； 若为非竞争的随机接入过程， 则执行歩骤 603， 否则执行歩骤 607。
歩骤 603，在歩骤 602中，若随机接入类型为非竞争的随机接入过程， 则该用户设备 UE根据预先配置的与该非竞争的随机接入过程对应的 RAR 消息的格式对该 RAR消息进行相应的处理， 以获得该 RAR消息中包含的 指示信息；
其中， 对该 RAR消息进行处理是指对该 RAR消息进行解码。
歩骤 604，判断该指示信息的类型是否为发送非周期的测量参考信号 SRS的指示信息； 若判断结果为是， 则执行歩骤 605， 否则执行歩骤 607; 其中， 若该指示信息为 " 1 "， 则表示发送非周期的 SRS; 若该指示信 息为 " 0 "， 则表示不发送非周期的 SRS。 歩骤 605， 在歩骤 604中， 判断结果为是， 即该指示信息的类型为发 送非周期的测量参考信号 SRS的指示信息， 则用户设备 UE确定发送非周 期的 SRS。
歩骤 607， 在歩骤 604中， 判断结果为否， 即该指示信息的类型为不 发送非周期的测量参考信号 SRS的指示信息， 则用户设备 UE确定不发送 非周期的 SRS。
歩骤 606， 在歩骤 602中， 若随机接入类型为竞争的随机接入过程， 则该用户设备 UE根据默认的 RAR消息的格式对该 RAR消息进行处理， 可 知该 RAR消息中不包括指示信息， 或该指示信息为 " 0 "， 则可确定不发 送非周期的 SRS。
由上述可知， 基站可通过随机接入过程的 RAR消息触发用户设备 UE发送非周期的测量参考信号 SRS , 在未释放的资源上发送该非周期的 SRS , 使得基站快速获得该用户设备的上行信道状态信息 CSI, 从而快速 调度用户设备 UE的上行数据的传输。
图 7是本发明实施例 4的触发非周期的测量参考信号的方法流程图。 其中， 由于随机接入过程可由用户设备 UE自发或者由基站触发， 因此， 该用户设备 UE可自发或者基于基站触发向基站发送随机接入前导；基站 在接收到用户设备 UE 发送的随机接入前导后， 若该基站需要用户设备 UE发送非周期的 SRS ,则在返回的 RAR消息中携带指示该用户设备 UE 发送非周期的 SRS的指示信息， 以触发该用户设备 UE的非周期的 SRS ; 否则在返回的 RAR消息中携带指示该用户设备不发送非周期的 SRS的指 示消息。
如图 7所示， 该方法包括：
歩骤 701， 基站接收用户设备 UE发送的随机接入前导；
歩骤 702，根据预先配置的随机接入响应消息的格式、或者根据预先 配置的与随机接入类型对应的随机接入响应消息的格式生成相应的随机 接入响应消息， 其中， 该随机响应消息中包含指示该用户设备 UE是否发 送非周期的测量参考信号的指示信息；
歩骤 703， 向该用户设备 UE发送该随机接入响应消息， 以使该用户 设备 UE根据该随机接入响应消息中包含的指示信息的类型确定是否发送 非周期的测量参考信号 SRS。
其中， 若由基站触发随机接入过程， 则该方法还包括该基站触发用 户设备 UE发起随机接入过程， 与现有技术类似， 此处不再赘述。
其中， 若该基站需要用户设备 UE发送非周期的 SRS, 则在返回的 RAR消息中携带指示该用户设备 UE发送非周期的 SRS的指示信息， 以 触发该用户设备 UE的非周期的 SRS; 否则在返回的 RAR消息中携带指 示该用户设备不发送非周期的 SRS的指示消息； 此外， 该 RAR消息中除 了包含上述指示信息外， 还可包括随机接入过程的其他信息， 例如， 包 括用于上行同歩的时间调整信息、 为用户设备 UE分配上行数据传输所需 要的资源、 以及临时无线网络临时标识 C-RNTI等信息。
在本实施例中， 在歩骤 702中， 若基站根据预先配置的随机接入响 应消息的格式生成相应的 RAR消息时， 可具体包括： 当基站接收到用户 设备 UE发送的随机接入前导时，若根据该随机接入前导确定该用户设备 UE的随机接入过程为竞争的随机接入过程时， 在生成预先配置的格式的 RAR消息时， 将该指示信息设置为 "0"; 若确定该用户设备 UE的随机 接入过程为非竞争的随机接入过程， 则该基站可根据先确定是否需要该 用户设备 UE发送非周期的 SRS,若确定需要该用户设备 UE发送非周期 的 SRS 时， 可将该指示信息设置为 " 1 "， 若确定部需要该用户设备 UE 发送非周期的 SRS时， 可将该指示信息设置为 "0"。
在本实施例中， 在歩骤 702中， 若基站根据预先配置的与随机接入 类型对应的随机接入响应消息的格式生成相应的随机接入响应消息时， 可具体包括：
当基站接收到用户设备 UE发送的随机接入前导时， 若根据该随机 接入前导确定该用户设备 UE的随机接入过程为竞争的随机接入过程时， 可生成默认的原有格式的 RAR消息， 其中不包含指示信息， 或者将原有 格式中的预留比特 R设置为 "0 "， 指示用户设备 UE不发送非周期的 SRS; 若为非竞争的随机接入过程， 采用配置的与非竞争的随机接入过程对应 的随机接入响应消息的格式， 其中， 若基站确定需要用户设备 UE发送非 周期的 SRS时， 将指示信息设置为 " 1 "， 否则将指示信息设置为 " 0"。
在本实施例中， 该 RAR消息中包含的指示信息由该 RAR消息中的预 留比特来承载、或者由新增的比特来承载，如由上行带宽授予（UL Grant ) 域中新增比特 bit来承载。 以下举例说明。
图 8是现有技术中 RAR消息的格式示意图； 图 9是采用 RAR消息中 的预留的比特 "R"来承载该指示信息的 RAR消息的格式示意图， 其中， 表示该指示信息的比特用 " S "表示； 图 10是采用 RAR上行带宽授予（UL Grant ) 域中新增比特来承载指示信息的 RAR消息的格式示意图。

Figure imgf000021_0001
如图 9所示， 禾 1」用预留比特 R来承载该指示信息， 该预留比特 R为 lbito将 Rbit设置为触发非周期的 SRS的 bit "S" 。 例如， 若基站需要 触发用户设备 UE发送非周期的 SRS, 则可以将 S 设置为 " 1 "; 若基站不 需要触发用户设备 UE发送非周期的 SRS , 可以将 S设置为 "0 "。 这样， 当用户设备 UE接收到图 9所示的格式的 RAR消息时，可进行相应的解码， 以获得该 "S " bit承载的指示信息， 并根据指示信息的类型确定是否发 送非周期的 SRS。在这种情况下， 对原有的 RAR消息的格式的变动不是很 大， 便于实际应用。
如图 10所示， 利用新增的比特来承载该指示信息， 例如， 在上行带 宽授予 （UL grant) 域中新增一个 bit用于触发非周期的 SRS， 这样， 在 UL grant域中的比特数为 21bit。 包含的参数和 bit数如表 2所示。
表 2
Figure imgf000022_0001
如表 2所示， 若基站需要触发用户设备 UE发送非周期的 SRS , 则可 以将非周期 SRS请求 bit 设置为 " 1 "; 若基站不需要触发用户设备 UE发 送非周期的 SRS , 可以将非周期 SRS比特设置为 " 0 "。 这样， 当用户设备 UE接收到图 10所示的格式的 RAR消息时， 可进行相应的解码， 以获得非 周期 SRS请求所承载的指示信息， 并根据指示信息的类型确定是否发送 非周期的 SRS。 在这种情况下， 对原有的 RAR消息的格式变动较大。 如图 10所示， 该 RAR消息的总的 bit数不变， 其只是改变了该 RAR消息的格 式， 将原预留比特 R增设到 UL grant域中。
由上述可知， 由于采用不同的承载方式， 该 RAR消息可对应不同的 格式， 不同格式的 RAR消息对应不同的处理方式。 其中， 该 RAR消息的 格式可由基站预先配置并通知用户设备 UE，以使用户设备 UE在接收到该 RAR消息时， 根据配置的格式进行相应的处理； 或者由基站预先根据随机 接入过程的类型来配置相应的 RAR消息的格式， 即可针对非竞争的随机 接入过程配置图 9或图 10所示的格式， 针对竞争的随机接入配置图 8所 示的格式， 并通知该用户设备 UE， 以使该用户设备 UE在接收到该 RAR消 息时， 根据配置的与随机接入类型对应的格式作相应的处理。
这样， 该方法还可包括： 该基站为该用户设备 UE配置发送非周期的 测量参考信号 SRS所使用的资源信息； 将配置的该资源信息通过无线资 源控制（RRC: Radio Resource Control )信令通知该用户设备 UE。 其中， 该无线资源控制信令可为无线资源控制连接建立信令 （RRC Connection Setup ) , 或者无线资源控制连接重配置信令 （RRC Connection Reconfiguration ) , 或者无线资源控制连接重建信令 （RRC Connection Reestabl ishment ) 0 但不限于此， 还可根据需要采用其他信令来实现。
在本实施例中， 该方法还包括： 该基站为该用户设备 UE配置该 RAR 消息的格式； 将配置的 RAR消息的格式通知该用户设备 UE, 以使该用户 设备 UE根据该随机接入响应消息的格式对接收到的 RAR消息进行相应的 处理。 其中， 若预先配置 RAR消息的格式， 则在歩骤 701 中， 基站在接 收到该用户设备 UE发送的随机接入前导后， 根据预先配置的 RAR消息的 格式生成相应的 RAR消息， 使得用户设备 UE在接收到该 RAR消息后， 进 行相应的处理。 在这种情况下， 无论竞争的随机接入还是非竞争的随机 接入过程， 其 RAR消息的格式均为预先配置的格式。
在本实施例中， 该方法还包括： 该基站为该用户设备 UE配置与非竞 争的随机接入过程对应的 RAR消息的格式； 将配置的与随机接入过程对 应的 RAR消息的格式通知该用户设备 UE，以使该用户设备 UE根据随机接 入过程和与该随机接入过程对应的 RAR消息的格式对接收到的 RAR消息 进行相应的处理。 其中， 若随机接入过程为竞争的随机接入过程时， 可 预先配置 RAR消息的格式为图 8所示的格式； 若随机接入为非竞争的随 机接入， 则可预先配置 RAR消息的格式为图 9或图 10所示的格式， 在歩 骤 701中， 基站在接收到该用户设备 UE发送的随机接入前导后， 根据随 机接入竞争的类型生成相应的 RAR消息，使得用户设备 UE在接收到该 RAR 消息后， 根据随机接入竞争的类型进行相应的处理。
由上述实施例可知， 当基站接收到用户设备 UE发送的随机接入前 导时， 可根据预先配置返回相应格式的 RAR消息， 使得用户设备 UE接 收到基站发送的 RAR消息后， 根据预先配置的格式对该 RAR消息进行 处理， 以获得相应的指示信息，在该指示信息指示用户设备 UE发送非周 期的 SRS 时， 利用未释放的资源向基站发送该非周期的测量参考信号 SRS, 使得该基站快速地获得用户设备 UE的上行信道状态信息 CSI, 从 而快速地调度用户设备 UE的上行数据的传输。
