Description

参数获取方法、 基站和终端设备 技术领域
本发明涉及一种通信领域, 特别涉及一种进行随机接入优化的参数 获取方法、 基站和终端设备。 背景技术
在无线通信系统中, 为了实现上行链路同步, 终端设备需要进行上 行随机接入过程。 只有上行链路实现了同步之后, 终端设备才能与基站 进行上下行数据和消息的传输。
为了提高随机接入过程的成功率且减少延时, 需要进行随机接入信 道 (RACH: Random Access Channel) 优化。 在 Rel.9的增强的长期演进 (LTE-A: long term evaluation Advanced) 系统 (非载波聚合系统) 中, 为了进行优化, 基站要求终端设备报告与随机接入过程相关的一些参数, 其中, 这些参数只有通过终端才能获得, 基站无法直接获取。
图 1是现有技术中基站获取终端报告的参数的流程图。如图 1所示, 基站 (eNB ) 首先向该用户设备(UE: User Equipment)发送报告随机接 入过程相关参数的请求, 其中可通过 UE Information Request消息发送; 该用户设备 UE接收到该请求后,通过 UE Information Response消息将与 随机接入过程相关的参数提供给该基站; 其中, 主要包括两个参数:
1 )发送随机接入前导的数量: 是指最后一次成功完成的随机接入过 程中被介质访问控制 (MAC: Media Access Control) 层发射的随机接入 前导的数量;
2)是否检测到竞争: 若该最后一次成功完成的随机接入过程中, 至 少有一个被发射的随机接入前导被检测到存在竞争, 则设置 "true "; 否 则设置 "false"。
该基站在接收到小区中该终端设备关于上述两个参数的报告之后, 该基站或网络侧的某些实体可通过优化算法, 对接入信道的某些参数进 行重配置, 进行相关优化, 以提高终端接入的成功率或减少时延。
由上述可知, Rel.9的 LTE-A系统是一个非载波聚合系统, 即服务小 区中对某个终端设备来讲, 只有一个载波, 显然随机接入过程只发生在 唯一的载波上。
图 2是载波聚合示意图。 在载波聚合 (CA: Carrier Aggregation) 系 统中, 如图 2所示, 终端可以工作在最多 100MHz的带宽内, 即可以聚 合 5个载波。 对于多载波系统, 可分为单带(intra-band) CA系统和多带 ( inter-band ) C A系统。
其中, 在单带 CA系统中, 随机接入过程在主载波上进行, 不在辅 载波上进行, 这样, 对于某个终端来讲, 随机接入过程只发生在一个载 波上。
另外, 在多带 CA系统中, 随机接入过程不仅仅发生在主载波上, 还会发生在其他波带的辅载波上, 因此, 对于某个终端来讲, 随机接入 过程发生的位置 (哪个载波) 不唯一。
因此, 发明人在实现本发明的过程中发现现有技术的缺陷在于: 在 一个多带 CA系统中, 随机接入信道在每个波带中是相对独立, 若网络侧 对随机接入信道进行优化时, 如仍然采用如图 1 所示的过程, 则基站无 法获知终端设备上报的参数所涉及的随机接入过程发生在哪个波带上, 因此, 网络侧无法进行相应的优化; 另外, 在现有技术中也没有提供解 决上述问题的办法。

(LTE-A: long term evaluation advanced) 系统中的多带的 CA系统为例 进行介绍, 但是应该理解, 本发明不限于该系统, 可用于任何涉及随机 接入过程发生的位置不唯一的系统。
图 3是本发明实施例 1的参数获取方法流程图。 如图 3所示, 该方 法包括:
步骤 301,终端设备接收基站发送的上报在至少一个载波上发生的随 机接入过程的相关参数的请求消息, 该请求消息包括载波标识信息; 步骤 302,该终端设备根据请求消息将至少一个载波上发生的随机接 入过程的相关参数向基站发送, 使得网络侧利用相关参数进行相应的随 机接入优化;
其中, 该相关参数包括: 在该至少一个载波上, 最后一次成功完成 的随机接入过程中发射的随机接入前导的数量、 以及在最后一次成功完 成的随机接入过程中是否至少一个随机接入前导被检测到存在竞争的信息。
在本实施例中, 在步骤 301 中, 该请求消息可采用 UE Information Request消息; 在步骤 302中, 该终端设备接收到该请求消息后,通过 UE Information Response消息返回相关参数。
在本实施例中, 在步骤 301 中, 该基站可在请求消息中携带指示终 端需要报告的随机接入过程的相关参数所在的载波, 即需要携带载波标 识信息; 这样, 在步骤 302 中, 该终端设备接收到请求消息后, 可根据 该请求消息中携带的载波标识信息上报该相关参数, 并且在返回相关参 数时, 不需要再上报该载波标识信息。
其中, 若基站在步骤 301 的请求消息中指示需要上报在一个载波上 进行随机接入过程的相关参数, 如载波 Cj, 则终端设备在步骤 302中直 接将在载波 Cj上进行随机接入过程的相关参数发送至该基站; 若基站在 步骤 301 中指示需要上报在多个载波上进行随机接入过程的相关参数, 则终端设备可以在步骤 302 中按照预设的规则上报在多个载波上进行随 机接入过程的相关参数, 而不需要再上报载波标识信息。 例如, 按照请 求消息中载波标识信息的排列顺序, 对上报的随机接入过程的相关参数 进行排序, 并依序向基站发送。 这样, 该基站可依序接收到与发送的载 波标识信息对应的相关参数。
在本实施例中, 该相关参数中包括的 "在最后一次成功完成的随机 接入过程中是否至少一个随机接入前导被检测到存在竞争的信息"可以 采用 " 0 "或 " 1 "表示, 例如, " 0 "表示存在竞争, " 1 "表示不存在, 反之亦然; 此外, 还可用 " true "或 " false ", 如背景技术所述, 此处 不再赘述。 但不限于上述表示方式, 还可采用其他任何符号表示。
在本实施例中, 可根据系统配置、 或者根据每个波带上进行随机接 入过程的载波的数量来确定载波标识信息。 其中,
1 ) 当系统为每个载波顺序分配载波识别信息, 如载波识别符, 该载 波识别符可唯一识别载波, 这时, 该载波标识信息可为该载波识别符, 例如, 在 Rel. 10中, 对于每个终端来讲, 其主载波和辅载波都有唯一的 编号, 为 ServCel l lndex, 这时候, 就可以用 ServCel llndex来作为在该 至少一个载波上的载波识别符;
这样, 该终端设备可根据该载波识别符将相应载波上发生的随机接 入过程的相关参数向基站发送。
2 )在每个波带中只有一个载波能够进行随机接入时, 该载波标识信 息可采用波带识别信息, 如波带识别符来表示; 例如, 该终端设备有三 个波带, 其波带识别符为: band0、 bandl和 band2。 同时, bandO中有两 个载波: carrierO禾口 carrierl。 bandl中有三个载波: carrier0、 carrierl 禾口 carrier2。 band2中有两个载波: carrierO禾口 carrier 1。 在该三个波 带中, 若都是在一个载波, 如 carrierO上进行随机接入, 则可以采用波 带识别符, 如 band0、 bandl或 band2来作为载波标识符。
这样, 该终端设备可根据请求消息中的波带识别符将相应载波上发 生的随机接入过程的相关参数向基站发送。
3 )在每个波带中有一个以上载波能够进行随机接入, 并且载波标识 信息在同一波带内部唯一, 但在不同波带之间不唯一时, 该载波标识信 息需要同时包括波带识别信息和载波识别信息; 例如, 该终端设备有三 个波带, 其波带识别信息, 如波带识别符为: band0、 bandl 和 band2。 同时, bandO中有两个载波: carrierO禾卩 carrierl。 bandl 中有三个载 波: carrierO^ carrier 1禾口 carrier2。 band2中有两个载波: carrierO 和 carrier 1。 在波带 bandO中, 在 carrierO上进行随机接入; 在波带 bandl禾口 band2中, 在 carrierO 禾口 carrierl上进行随机接人。 这样, 就需要同时采用波带识别信息如波带识别符、 以及波带内部的载波识别 信息, 如载波识别符作为请求消息中的载波标识信息。
这样, 终端设备根据请求消息中的波带识别符和载波识别符将相应 载波上发生的随机接入过程的相关参数向基站发送。

由上述实施例可知, 在多带载波系统中, 基站可指示终端设备上报 相关载波上发生的随机接入过程的相关参数, 使得网络侧能够利用该相 关参数对相应载波上的随机接入信道进行优化, 从而减少延时且提高随 机接入的成功率, 解决了现有技术中在多带载波系统中存在的问题。
图 4是本发明实施例 2的参数获取方法流程图。 如图 4所示, 该方 法包括:
步骤 401,基站向终端设备发送上报在至少一个载波上发生的随机接 入过程的相关参数的请求消息, 该请求消息中包括载波识别信息;
步骤 402,该基站接收终端设备根据该请求消息返回的至少一个载波 上发生的随机接入过程的相关参数, 以使该基站利用该相关参数进行相 应的随机接入优化; 其中, 该相关参数包括: 在该至少一个载波上, 最 后一次成功完成的随机接入过程中发射的随机接入前导的数量、 以及在 最后一次成功完成的随机接入过程中是否至少一个随机接入前导被检测 到存在竞争的信息。
在本实施例中, 该基站可指示终端设备上报相关载波上发生的随机 接入过程的相关参数, 这样, 该终端设备上报相关参数时, 可不上报载 波标识信息。 其中, 该载波标识信息可为一个或一个以上。 在本实施例中, 该基站发送的载波标识信息与实施例 1类似, 此处 不再赘述。
此外, 在本实施例中, 该方法还可包括: 该基站将相关参数向网络 侧其他功能实体发送, 使得网络侧其他功能实体利用相关参数进行相应 的随机接入优化。 例如, 该基站可通过核心网将该相关参数向网络管理 系统发送, 使得该网络管理系统根据相关参数进行相应的随机接入优化。
由上述实施例可知, 在多带载波系统中, 基站可指示终端设备上报 相关载波上发生的随机接入过程的相关参数, 使得网络侧能够对相应载 波上的随机接入信道进行优化, 从而减少延时且提高随机接入的成功率, 解决了现有技术中在多带载波系统中存在的问题。
以下以在多带 CA系统中, 基站指示终端设备上报在至少一个载波 上发生的随机接入过程的相关参数为例, 对该方法进行详细说明。
图 5是本发明实施例 3的参数获取方法流程图。 如图 3所示, 该方 法包括:
步骤 501,基站根据随机接入优化算法的需要,判断是否需要终端设 备上报随机接入过程的相关参数; 若判断结果为是, 则执行步骤 502, 否 则继续进行判断。
步骤 502, 在步骤 501中, 若判断结果为需要, 则发起请求; 其中, 该基站可通过随机接入信息请求消息, 如 UE Information Request消息发送该请求, 并在该随机接入信息请求消息中指示该终端设 备需要上报的载波 q上的随机接入过程的相关参数;
其中, 在该消息中包括载波标识信息, 且载波标识信息如实施例 1 和 2所述, 此处不再赘述;
该相关参数包括: 在载波 Cj上, 最后一次成功完成的随机接入过程 中发射的随机接入前导的数量、 以及在最后一次成功完成的随机接入过 程中是否至少一个随机接入前导被检测到存在竞争的信息。
步骤 503, 该终端设备接收到该请求消息。
步骤 504, 该终端设备根据该请求消息中的载波标识信息将载波 Cj 上发生的随机接入过程的相关参数通过响应消息向该基站发送;
其中, 该响应消息可为随机接入信息响应消息, 如 UE Information Response消息, 此时, 由于基站明确指示上报载波 Cj上的随机接入过程 的相关参数, 因此, 在该响应消息中可以不包括载波标识信息。
步骤 505,该基站判断是否接收到终端设备根据该请求消息返回的响 应消息; 若判断结果为接收到, 则执行步骤 506, 否则执行步骤 508。
步骤 506, 在步骤 505中, 若该基站接收到终端设备返回的响应消 息,则该基站将在载波 Cj上的相关参数与保存的载波 q的标识信息组合 在一起作为随机接入优化算法的输入参数;
步骤 507,该基站利用该输入参数采用预定的随机接入优化算法进行 随机接入优化;
其中, 该基站作为网络侧执行优化算法的实体, 该随机接入优化算 法可采用现有的任何一种优化算法此处不再赘述。
步骤 508, 在步骤 505中, 若判断结果为基站未接收到该响应消息, 则该基站判断计时器是否超时, 若未超时则回到步骤 505; 若超时, 则该 基站可确定未接收到响应消息, 过程结束。
此外, 除了将基站作为网络侧随机接入优化算法的实体, 还可将网 络侧其他功能实体作为执行随机接入优化算法的实体, 例如, 可以利用 网络管理系统执行随机接入优化算法。 这样, 在步骤 506之后, 还可包 括步骤 509。
步骤 509,该基站将在载波 Cj上的相关参数与保存的载波 Cj的标识 信息组合在一起后的参数通过网络发送到其他功能实体。
步骤 510,该其他功能实体根据组合在一起后的参数进行随机接入优化。 在上述实施例中, 在步骤 502中, 以基站指示上报一个载波 Cj上的 随机接入过程的相关参数为例进行了说明。 此外, 该基站还可指示上报 一个载波以上的随机接入过程的相关参数, 这样, 在步骤 502 中的随机 接入信息请求消息中包含的载波标识信息可为一个以上的载波标识信 息。 在这种情况下, 在步骤 504 中, 该终端设备可按照预设的规则上报 在多个载波上进行随机接入过程的相关参数, 而不需要再上报载波标识 信息。 例如, 按照随机接入信息请求消息中载波标识信息的排列顺序, 对上报的随机接入过程的相关参数进行排序, 并依序向基站发送。 这样, 该基站可依序接收到与发送的载波标识信息对应的相关参数。 在本实施例中, 进行随机接入优化包括: 对在随机接入过程中, 该 基站通知给该终端设备的、 与随机接入相关的参数进行优化, 其中, 需 要动态调整优化的参数包括: 随机接入信道的信道配置参数、 随机接入 信道的传输功率控制参数、 随机接入信道的后退参数和随机接入信道前 导集的分割参数等。
例如, 在随机接入信道的传输功率控制参数中有参数: 功率进阶。 该基站若在上次前导发送失败后, 则在下次发射前导时增加功率, 每次 增加的值为功率进阶。 该值若太小, 则即使该终端在达到了最大前导发 射次数之后, 发射功率值依然不足以克服传播损耗和干扰, 该基站不能 够成功接收到前导; 若该值太大, 该终端的前导发射功率很快就达到很 高, 则将会给其它终端造成不必要的干扰。 因此, 需要对功率进阶进行 优化。 在优化时, 该基站需要小区内的所有终端设备上报在一个或一个 以上的载波上成功完成的随机接入过程中发射的前导数量和在这次随机 接入过程中是否检测到竞争, 这样, 基站可利用每个终端设备上报的相 关参数进行优化。 即通过统计在某个载波上所有终端设备的上述两个参 数, 若该基站发现终端设备随机接入过程中发射的前导数量普遍较多, 这就意味着时延较长, 但是检测到竞争的终端又较少, 说明随机接入过 程的延迟主要是因为终端发射前导的功率不够, 而不是因为接入资源发 生竞争 (即多个终端在相同的接入信道同时发射相同的前导, 因此就会 发生碰撞, 产生竞争。 这通常是因为接入信道过少或终端可选的前导过 少) 引起的。 这时, 可以初步判断功率进阶有可能过小, 就需要进行调整。
在上述实施例中, 以功率进阶为例对参数优化进行说明, 此外, 对 上述其他参数的优化可采用现有的任何一种算法实现, 此处不再赘述。
由上述实施例可知, 在多带载波系统中, 基站可指示终端设备上报 相关载波上发生的随机接入过程的相关参数, 使得网络侧能够对相应载 波上的随机接入信道进行优化, 从而减少延时且提高随机接入的成功率, 解决了现有技术中在多带载波系统中存在的问题。

在本实施例中, 由于载波标识信息可包括所有载波或部分载波对应 的载波标识信息, 因此, 步骤 802 可具体包括: 该终端设备根据该请求 消息将在全部或部分载波上发生的随机接入过程的相关参数向该基站发 送。 其中,
