Description

用户设备覆盖增强资源的分配方法、 基站和用户设备 技术领域
本发明实施例涉及数据通讯技术, 尤其涉及一种用户设备覆盖增强资 源的分配方法、 基站和用户设备。 背景技术
物联网的发展,被誉为是继计算机和互联网之后信息产业的第三次浪潮, 简而言之, 物联网就是要实现人与物、 物与物的互联互通。 物联网的应用包 括智能电网、 智能农业、 智能交通、 以及环境检测等各个方面。 机器到机器 间的通信 (Machine to Machine, 简称 M2M ) 是第三代移动伙伴计划 (3rd Generation Partnership Project,简称 3GPP)为研究如何在移动通信网络上承载 物联网应用, 而提出的技术和标准化概念, 该研究针对机器类通信 (Machine-Type Communication, MTC) 设备的引入而需要对移动通信网络 进行的增强或优化。
目前 3GPP LTE项目针对 MTC设备的特殊应用场景提出了覆盖增强的针 对性研究课题: 针对处于地下室等路损较大的 MTC设备提供覆盖增强支持, 使得路损较大的 MTC设备能够接入网络。 覆盖增强技术主要包括信号重复, 功率借用(Power boosting)或者功率谱密度借用(PSD, Power Spectrum density boosting)等。 虽然路损较大的 MTC设备的路损远远大于传统用户设备(User Equipment, 简称 UE) 的路损, 但由于各 MTC设备离基站的距离不同、 所处 环境不同等原因, 导致上述各 MTC设备的路损也不同, 从而各 MTC所需要的 覆盖增强需求也就不一样。 比如, 有的 MTC设备不需要增强, 有的 MTC设备 需要增强 5dB, 有的 MTC设备则需要增强 10dB或者 15dB。 因而, 基站需要为 其服务范围内的不同覆盖增强需求的 MTC设备使用不同的覆盖增强技术, 配 置不同的覆盖增强资源。
现有技术中, 基站把覆盖增强需求分为几个等级, 并为不同的覆盖增 强等级的 MTC设备配置不同的资源, 覆盖增强等级越高, 覆盖增强程度 越高。 如为某个覆盖增强等级的 UE配置随机接入资源, 使用该等级对应 的覆盖增强技术发送物理广播信道 (Physical Broadcast Channel , 简称 PBCH) 信息和***信息块 (System Information Block, 简称 SIB ) , 为该 等级对应的用户设备配置数据传输资源等。 但是, 如果基站下面没有某个 覆盖增强等级的 MTC设备存在时,基站继续为该等级的 MTC设备配置覆 盖增强资源, 就会造成资源的浪费。

图 1为本发明用户设备覆盖增强的资源分配方法实施例一的流程图, 如图 1所示, 本实施例的方法可以包括:
步骤 101、 基站检测是否存在第一覆盖增强等级对应的用户设备 UE 的通信需求。
基站可以周期性的检测是否存在第一覆盖增强等级对应的 UE的通信 需求, 检测周期可根据实际的需要灵活配置。 基站把覆盖增强需求划分为 多个覆盖增强等级, 并为每个覆盖增强等级分配不同的覆盖增强资源, 该 覆盖增强资源可以为随机接入资源。 不同的覆盖增强等级可以使用不同的 覆盖增强技术, 以达到不同的覆盖增强程度来满足各覆盖增强等级对应的
UE 的通信需求。 一般情况下, 覆盖增强等级的级别越高, 覆盖增强等级 的增强程度也相应的越高, 本发明各实施例中, 如果不做特别说明, 覆盖 增强级别高的覆盖增强等级对应的覆盖增强程度也高。基站检测是否存在 第一覆盖增强等级对应的 UE的通信需求, 有以下两种情况:
第一种情况, 基站为第一覆盖增强等级预先分配了覆盖增强资源, 该 覆盖增强资源与第一覆盖增强等级的级别对应, 而不同级别的覆盖增强等 级对应的 UE的通信需求不同。 这种情况下, 基站检测是否存在第一覆盖 增强等级对应的 UE的通信需求具体为: 基站检测是否有第一覆盖增强等 级对应的 UE使用为第一覆盖增强等级分配的覆盖增强资源。 如果基站预 先为一覆盖增强等级分配了覆盖增强资源, 则第一覆盖增强对应的 UE可 以使用该覆盖增强资源与基站进行通信, 比如使用分配的随机接入资源发 起随机接入过程, 在分配的数据资源上发送数据等, 基站只需判断该覆盖 增强资源有没有被使用, 比如, 在预定义的检测周期内, 有没有第一覆盖 增强对应的 UE使用过该覆盖增强资源与基站通信。
第二种情况, 基站没有为第一覆盖增强等级预先分配覆盖增强资源, 则基站检测是否存在第一覆盖增强等级对应的 UE的通信需求具体为: 基 站检测在预留资源上是否接收到第一覆盖增强等级对应的 UE发送的第一 序列。 该预留资源为基站为第一覆盖增强等级对应的 UE预留的, 以便第 一覆盖增强等级对应的 UE在基站没有为其分配覆盖增强资源时, 通过该 预留资源和第一序列通知基站自己的通信需求, 基站根据第一覆盖增强等 级对应的 UE的通信需求为该 UE分配覆盖增强资源。
需要说明的是, 这里基站没有为第一覆盖增强等级预先分配覆盖增强 资源, 是指基站没有为第一覆盖增强等级分配除该预留资源和该第一序列 之外的资源。相应的,基站为第一覆盖增强等级预先分配了覆盖增强资源, 是指基站为第一覆盖增强等级分配了除该预留资源和该第一序列之外的 资源。 预先分配的覆盖增强资源, 用于向第一覆盖增强等级对应的 UE发 送广播信道, 比如物理广播信道, ***消息块等; 还可以用于第一覆盖增 强等级对应的 UE发起随机接入过程; 还可以用于第一覆盖增强等级对应 的 UE与基站之间的数据通信。
步骤 102、 基站根据检测结果, 调整为第一覆盖增强等级分配的覆盖 增强资源。
当基站为第一覆盖增强等级预先分配了覆盖增强资源, 且检测出有第 一覆盖增强等级对应的 UE使用为第一覆盖增强等级分配的覆盖增强资源 时, 基站根据检测结果, 调整为第一覆盖增强等级分配的覆盖增强资源具 体为: 基站保持或增加为第一覆盖增强等级分配的覆盖增强资源, 比如基 站继续使用原有发送周期以第一覆盖增强等级对应的覆盖增强技术发送 广播信道, 或者使用较短的发送周期以第一覆盖增强等级对应的覆盖增强 技术发送广播信道, 包括物理广播信道, ***消息块等; 或者, 基站继续 在为第一覆盖增强等级分配的随机接入资源上接收第一覆盖增强等级对 应的 UE发起的随机接入过程, 或者为第一覆盖增强等级分配更多的随机 接入资源; 或者, 基站继续在为第一覆盖增强等级对应的 UE分配的数据 资源上与第一覆盖增强等级对应的 UE通信等, 或者为第一覆盖增强等级 对应的用户设备分配更多的数据资源等。
当基站为第一覆盖增强等级预先分配了覆盖增强资源, 但检测出没有 第一覆盖增强等级对应的 UE使用为第一覆盖增强等级分配的覆盖增强资 源时, 说明为该第一覆盖增强等级分配的覆盖增强资源空闲, 则基站根据 检测结果, 调整为第一覆盖增强等级分配的覆盖增强资源具体为: 基站取 消或者减少为第一覆盖增强等级分配的覆盖增强资源, 比如停止以第一覆 盖增强等级对应的覆盖增强技术发送广播信道, 或者使用较大的发送周期 以第一覆盖增强等级对应的覆盖增强技术发送广播信道, 包括物理广播信 道, ***消息块等; 取消或者减少为第一覆盖增强等级分配的随机接入资 源; 取消或者减少为第一覆盖增强等级对应的 UE分配的数据资源等。
当基站没有为第一覆盖增强等级预先分配覆盖增强资源, 且在预留资 源上检测到第一覆盖增强等级对应的 UE发送的第一序列时, 基站根据检 测结果, 调整为第一覆盖增强等级分配的覆盖增强资源具体为: 基站根据 预留资源和 /或第一序列为第一覆盖增强等级分配覆盖增强资源。比如基站 定义一个发送周期, 并开始以第一覆盖增强等级对应的覆盖增强技术, 使 用上述定义的发送周期发送广播信道,包括物理广播信道,***消息块等; 基站开始为第一覆盖增强等级分配随机接入资源, 并在分配的随机接入资 源上接收第一覆盖增强等级对应的 UE发起的随机接入过程; 基站开始为 第一覆盖增强等级对应的 UE分配数据资源, 并在所分配的数据资源上与 第一覆盖增强等级对应的 UE通信等。
基站可以使用本实施例提供的方法, 检测其服务范围内是否存在有覆 盖增强需求的 UE。 比如, 基站检测到有任何覆盖增强等级的 UE的通信 需求, 则认为其服务范围内存在有覆盖增强需求的 UE; 否则, 基站没有 检测到任何覆盖增强等级的 UE的通信需求, 则认为其服务范围内不存在 有覆盖增强需求的 UE。 举例来说, 基站把覆盖增强等级简单的分为需要 覆盖增强的覆盖增强等级 1 和不需要覆盖增强的覆盖增强等级 0 两个等 级, 如果基站检测到覆盖增强等级 1的 UE的通信需求, 则认为其服务范 围内存在有覆盖增强需求的 UE。
相应的, 如果基站使用本实施例提供的方法检测其服务范围内是否有 覆盖增强需求的 UE存在时, 若有, 且基站为有覆盖增强需求的用户设备 UE 预先分配了覆盖增强资源, 则调整为第一覆盖增强等级分配的覆盖增 强资源具体为: 基站保持或者增加为覆盖增强需求 UE分配的覆盖增强资 源, 比如, 继续使用原有发送周期以覆盖增强的方式发送广播信道, 或者 使用较短的发送周期以覆盖增强的方式发送广播信道, 包括物理广播信 道, ***消息块等; 继续在为有覆盖增强需求的 UE分配的随机接入资源 上接收有覆盖增强需求的 UE发起的随机接入过程, 或者为有覆盖增强需 求的 UE分配更多的随机接入资源; 继续在为有覆盖增强需求的 UE分配 的数据资源上与有覆盖增强需求的 UE通信等, 或者为有覆盖增强需求的 UE 分配更多的数据资源等; 若基站检测到其服务范围内有覆盖增强需求 的 UE存在, 且基站没有为有覆盖增强需求的 UE预先分配资源, 基站为 由有覆盖增强需求的 UE分配覆盖增强资源, 比如, 定义一个发送周期, 并开始以覆盖增强的方式使用上述定义的发送周期发送广播信道, 包括物 理广播信道, ***消息块等; 开始为有覆盖增强需求的 UE分配随机接入 资源, 并在分配的随机接入资源上接收有覆盖增强需求的 UE发起的随机 接入过程; 开始为有覆盖增强需求的 UE分配数据资源, 并在所分配的数 据资源上与有覆盖增强需求的 UE通信等; 若无, 且基站为有覆盖增强需 求的 UE预先分配了资源, 基站取消或者减少为有覆盖增强需求的 UE分 配的覆盖增强资源, 比如停止以覆盖增强的方式发送广播信道, 或者使用 较短的发送周期以覆盖增强的方式发送广播信道, 包括物理广播信道, 系 统消息块等;取消或者减少为有覆盖增强需求的 UE分配的随机接入资源; 取消或者减少为有覆盖增强需求的 UE分配的数据资源上等。
基站可以使用本实施例提供的方法, 检测基站当前的提供的覆盖增强 等级是否足够。 比如, 基站检测到高于当前支持的最高覆盖增强等级的任 何覆盖增强等级对应的 UE发送的通信需求, 基站即认为当前提供的覆盖 增强等级不够, 基站可以提高支持的覆盖增强等级, 并使用调整后的覆盖 增强等级与相应的 UE通信。 比如使用提高后的覆盖增强等级对应的发送 周期和覆盖增强技术发送广播信道, 包括物理广播信道, ***消息块等; 为提高后的覆盖增强等级对应的 UE分配随机接入资源, 并在分配的资源 上接收提高后的覆盖增强等级对应的 UE发起的随机接入过程; 为提高后 的覆盖增强等级对应的 UE分配数据资源, 并在分配的资源上与提高后的 覆盖增强等级对应的 UE通信。
本实施例提供的方法, 基站通过检测是否存在第一覆盖增强等级对应 的 UE的通信需求, 根据检测结果, 调整为第一覆盖增强等级分配的覆盖 增强资源。 使得基站可以根据第一覆盖增强等级对应的 UE的覆盖增强需 求, 及时灵活的调整覆盖增强资源配置, 减少覆盖增强资源的浪费。
图 2为本发明用户设备覆盖增强资源的分配方法实施例二的流程图, 本实施例对图 1所示的方法进行详细说明, 本实施例主要针对基站没有为 第一覆盖增强等级分配覆盖增强资源的情况下, 基站如何检测该第一覆盖 增强等级对应的 UE的通信需求, 并为该第一覆盖增强等级对应的 UE分 配覆盖增强资源。 如图 2所示, 本实施例的方法可以包括以下步骤: 步骤 201 : 基站通过预定义的方式确定预留资源和第一序列。
该预留资源可以为第二覆盖增强等级对应的时频资源中的预留时频 资源。 该第一序列可以为第二覆盖增强等级对应的预留序列中的第二序列 中, 该第一序列还可以为第二覆盖增强等级对应的预留序列中的第二序列 经过变换后的序列。 该预留资源具体可以为随机接入资源, 第一序列具体 可以为 preamble资源。一种实现方式中, 该预留资源和第一序列专用于在 基站没有为第一覆盖增强等级分配覆盖增强资源时, 第一覆盖增强等级对 应的 UE通知基站自己的通信需求。 另一种实现方式中, 该预留资源和第 一序列不仅用于 UE向基站通知自己的通信需求, 而且 UE可以使用该预 留资源和第一序列继续完成随机接入过程。
其中, 第二覆盖增强等级的级别高于第一覆盖增强等级, 当第一覆盖 增强等级没有分配覆盖增强资源, 而比该第一覆盖增强等级级别高的第二 覆盖增强等级分配了覆盖增强资源, 则基站可以从第二覆盖增强等级的覆 盖增强资源中预留一部分时频资源给第一覆盖增强等级使用, 并从分配给 第二覆盖增强等级的序列中预留一个或者多个第一序列给第一覆盖增强 等级使用, 需要说明的是, 该第二覆盖增强等级对应的 UE不能继续在预 留给第一覆盖增强等级的该预留时频资源上使用第一序列。
本实施例中, 基站通过预定义的方式确定预留资源具体为: 基站根据 预定的周期和帧号确定预留资源, 其中, 帧号是无线帧号或者子帧号。
步骤 202、 基站向第一覆盖增强等级对应的 UE发送预留资源的配置 信息和 /或第一序列的配置信息, 以使第一覆盖增强等级对应的 UE使用预 留资源向基站发送第一序列。
基站通过预定义的方式确定预留资源和第一序列后, 还可以将该预留 资源的配置信息和 /或第一序列的配置信息发送给第一覆盖增强等级对应 的 UE。 一种方式中, 基站可以只向第一覆盖增强等级对应的 UE发送预 留资源的配置信息, 而不发送该第一序列的配置信息, 基站和第一覆盖增 强等级对应的 UE之间预先约定好该第一序列, 该 UE通过预定义的方式 确定该第一序列。 另一种方式中, 基站可以只向第一覆盖增强等级对应的 UE发送该第一序列的配置信息, 而不发送该预留资源的配置信息, 基站 和第一覆盖增强等级对应的 UE之间预先约定该预留资源, 该 UE通过预 定义的方法确定该预留资源。 当然, 该预留资源的配置信息和第一序列的 配置信息都可以由基站向该第一覆盖增强等级对应的 UE发送。
具体地, 基站可以通过物理广播信道(Physical Broadcast Channel, 简 称 PBCH)信息、 ***消息块(System Information Block, 简称 SIB )或者 媒体接入控制元素(Media Access Control Control Element,简称 MAC CE) 中的任意一种或其组合, 向第一覆盖增强等级对应的 UE发送预留资源的 配置信息和 /或第一序列的配置信息, PBCH和 SIB也可以为增强型的 ePBCH和 eSIB。
以下将通过一个具体的例子来说明, 图 3为覆盖增强等级的覆盖增强 资源的配置示意图, 如图 3所示, 基站根据各 UE的覆盖增强需求, 比如 路损范围,将覆盖增强等级划分为四个等级,分别为 CI_leVelO、 CIJevel CI_level2、 CI_level3, 其中, CI_le velO对应的 UE的覆盖增强需求最小, 相应的 CLlevdO覆盖增强等级的级别最低, 覆盖增强程度最小, 而
CI_level3覆盖增强等级对应的 UE的覆盖增强需求最大,相应的 CI_level3 覆盖增强等级的级别最高, 覆盖增强程度也最大。 图 3中, CUevdl和 CI_level3对应的 UE没有通信需求, 或者, 基站下面没有 CUevell和 CI_level3对应的 UE存在, 基站没有为这两个覆盖增强等级分配覆盖增强 资源。 以下将第一覆盖增强等级对应的 UE划分为三种类型, 若第一覆盖 增强等级对应的 UE能够接收 PBCH和 SIB , 则将第一覆盖增强等级对应 的 UE确定为类型 1用户设备, 若第一覆盖增强等级对应的 UE只能正确 接收 PBCH, 而不能正确接收 SIB , 则将第一覆盖增强等级对应的 UE确 定为类型 2用户设备, 若第一覆盖增强等级对应的 UE即不能接收 PBCH 也不能接收 SIB , 则将第一覆盖增强等级对应的 UE确定为类型 3用户设 备。
针对上述不同类型的用户设备, 基站可以采用不同的方式向用户设备 发送步骤 201确定的预留资源的配置信息和 /或第一序列的配置信息,以下 具体说明:
( 1 ) 类型 1用户设备第一覆盖增强等级对应的 UE能够接收 PBCH 和 SIB , 那么, 基站可以通过 PBCH和 /或 SIB向第一覆盖增强等级对应的 UE发送通过步骤 201中确定的预留资源和 /或第一序列。 比如, 在 SIB中 发送基站预留资源和第一序列。 如图 3中, 对于 CUevell来说, 基站支 持更高级别的覆盖增强等级的 CI_level2, Cljevell对应的 UE能够正确接 收 PBCH和 SIB , 所以, CI_levell对应的 UE能够获得基站的一些配置信 息, 比如可以获得 CI_leve2覆盖增强等级对应的覆盖增强资源。对于类型 1用户设备,基站配置给类型 1用户设备对应的覆盖增强等级 CUevell的 预留资源, 可以是比 CLlevdl更高级别的覆盖增强等级对应的随机接入 时频资源中的预设时频资源, 基站配置给类型 1用户设备对应的覆盖增强 等级 CUevdl的第一序列, 可以是比 CUevdl更高级别的覆盖增强等级 对应的随机接入 preamble序列中的预设 preamble序列。 比如, 预留 CI_level2对应的预设周期的时频资源,以及预留 CI_le vel2对应的 preamble 资源中的一个或者多个 preamble,以便 Cljevell对应的 UE出现在***中 时, 使用该预留的 preamble在该预设的时频资源上发起随机接入过程, 通 知基站 Cljevell等级的 UE出现, 使得基站为 CUevell等级的 UE配置 覆盖增强资源。 但是, CI_level2对应的 UE不能在上述预设的时频资源上 使用预设的 preamble发起随机接入过程, 由于基站可以判断是 CI_levell 对应的 UE发起的随机接入过程,从而能够根据 Cljevell对应的 UE的通 信需求, 为 CUevell分配合适的覆盖增强资源。
一种方式中, 通过定义一个变换 f, 使得 CUevell等级对应的 UE出 现在***中时, UE使用 f对 CI_leVe12中的预留序列中的第二序列的进行 处理, p=f(p), P为处理后序列, p为处理之前的第二序列, 并在 CI_level2 的预留时频资源上发送处理后的序列 P, 发起随机接入过程。 基站接收到 该变换后的序列 P通过逆变换得到 =?* ),如果检测到对应的预留序列, 则确定 CI_levell 对应的 UE有通信需求, 并根据 CUevell对应的 UE的 通信需求, 为 CUevell分配合适的覆盖增强资源。
需要说明的是, 第一覆盖增强等级使用第二个覆盖增强等级中的预留 时频资源和预留第一序列, 除发送通信需求之外, 还可以继续完成随机接 入过程。
( 2) 类型 2用户设备
当第一覆盖增强等级对应的 UE不存在时, 基站向该第一覆盖增强等 级对应的 UE只发送 PBCH而不发送 SIB ,该第一覆盖增强等级对应的 UE 只能正确接收 PBCH而不能正确接收 SIB。 那么, 基站可以通过 PBCH向 第一覆盖增强等级对应的 UE发送通过步骤 201中确定的预留资源和 /或第 一序列。如图 3所示, CI_leVe13是基站所能支持的最高级别的覆盖增强等 级, 如果基站检测到没有该最高覆盖增强等级对应的 UE存在, 基站选择 以该最高覆盖增强等级对应的覆盖增强技术向***中各覆盖增强等级的 UE发送 PBCH, 但是不向各覆盖增强等级对应的 UE发送 SIB , 那么, 各 覆盖增强等级对应的 UE可以完成 PBCH的正确接收, 而不能正确接收 SIB。
基站按照预定义的周期,向类型 2用户设备发送 PBCH,并且在 PBCH 中携带一个物理随机接入信道 (Physical Random Access Channel, 简称 PRACH)资源配置信息, PRACH资源配置信息包括 PRACH资源的周期, preamble信息和时频资源信息等, 则预留资源为以配置的 PRACH资源周 期出现的时频资源信息, 第一序列为配置的 preamble信息指示的序列; 或 者, PRACH资源的配置信息是预定义的, 只是与帧号相关, 周期性出现, 则预留资源是按照预定义的方式, 与帧号相关, 周期性出现的时频资源, 第一序列是按照预定义的方式, 与帧号相关, 周期性出现的一个或者多个 preamble序列。当 CI_level3对应的 UE有通信需求, UE就获取上述 PRACH 配置信息, 发送 preamble, 通知基站当前自己的有通信需求, 基站根据 UE的通信需求为 CI_level3对应的 UE分配覆盖增强资源。 上述配置的 PRACH信息中包含的 preamble资源和时频资源, 可以是按照最大覆盖增 强等级需求配置的, 比如配置支持最大的 preamble重复次数的时频资源, 当然, UE可以按照自己的实际需求选择 preamble的重复次数, 不一定按 照最大的重复次数去发送 preamble, 也可以对 preamble资源进行分组, 以 支持不同调整需求的 UE,比如等级 A的 UE有通信需求时,发送 preamble 分组 A对应的 preamble, 基站通过检查上述 preamble, 为等级 A分配满 足需求的覆盖增强资源。 需要说明的是, 对于类型 2用户设备和类型 3用户设备, 基站不仅可 以采用通知的方式告知第一覆盖增强等级对应的 UE的预留资源和第一序 歹 U , 也可以不通知 UE, UE采用预定义的方式确定预留资源和第一序列。
( 3 ) 类型 3用户设备
如图 3所示, CI_leVe13是基站所能支持的最高覆盖增强等级。如果基 站下没有该最高覆盖等级对应的用户设备存在, 基站可以选择既不以该最 该覆盖增强等级对应的覆盖增强技术发送 PBCH, 也不发送 SIB。 那么, 各覆盖增强等级对应的 UE既收不到 PBCH也收不到 SIB , 得不到***的 任何配置信息。 基站只能通过约定的方式确定预留资源和第一序列, 并不 能把所确定的预留资源和第一序列通知给 UE。 那么, 预留资源为周期性 出现的预留时频资源, 第一序列为周期性出现的预留序列。 UE通知基站 自己有通信需求的方法可以是, 在上述预留时频资源上发送第一序列。 系 统中各覆盖增强等级的所有 UE可以使用同一个序列, 也可以随机的从一 个序列组中选择一个序列。 第一序列也可以分成几个不同的组, 以发送序 列所在的组代表 UE的覆盖增强需求等级; 预留的时频资源可以是, UE 以下行同步信号为参考, 上行子帧中相对于下行同步信号时频位置的一个 偏移位置。 预留的时频资源也可以分成几个不同的组, 以使用的时频资源 所在的组代表 UE的覆盖增强需求等级; 发送的序列的次数也可以是几个 等级, 以发送序列的次数代表 UE的覆盖增强需求等级。
比如, UE通知基站的方法具体为, UE在每个子帧 (或者奇 /偶子帧) 都发送一个 preamble序列。 或者, 为了留足保护时间 (Guard Time, 简称 GT) , UE每半个无线帧的前面几个子帧发送 preamble序列, 剩余子帧留 作 GT。 基站在约定的时频位置去检测 UE发送的序列, 约定的时频位置 可以理解为, 在频域上的固定位置, 或者根据一定图样跳频的频域位置, 在时间上与 UE发送的时刻相对应。 采取和 UE发送方式对应的接收方式 去检测序列, 可以使用多个子帧联合接收。 由于基站可能改变上行载频的 位置, 所以, 基站需要根据自己是否发送了上行载频更新指示, 来判断自 己是否需要在上述约定的时频位置去检测接收 UE发送的序列。 在约定时 间上可以假定 UE和基站有一个大概的时间同步, 在约定的时间点 UE才 启动序列发送, 以减少 UE的能量消耗。 比如, 约定零点以后, UE才会 在该预留资源上发送该第一序列。 基站也在零点以后, 才开始在该预留资 源上检测该第一序列。
步骤 203、 基站检测在预留资源上是否接收到第一覆盖增强等级对应 的 UE发送的第一序列。
当基站没有为第一覆盖增强等级对应的 UE分配的覆盖增强资源时, 若该第一覆盖增强等级对应的 UE有了通信需求, 可以使用基站为该第一 覆盖增强等级对应的 UE预留的预留资源向基站发送第一序列, 通知基站 自己的通信需求。 然后, 基站周期性的检测是否存在第一覆盖增强等级对 应的 UE的通信需求, 若是, 即基站检测到在预留资源上是接收到第一覆 盖增强等级对应的 UE发送的第一序列, 则基站执行步骤 204, 为第一覆 盖增强等级分配覆盖增强资源。
步骤 204、基站根据预留资源和 /或第一序列为第一覆盖增强等级分配 覆盖增强资源。
可选地, 第一覆盖增强等级的预留资源与其他覆盖增强等级的预留资源 不同,则基站根据预留资源或第一序列为第一覆盖增强等级分配覆盖增强资 源具体为:基站根据第一覆盖增强等级的预留资源,确定第一覆盖增强等级 对应的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信需求 为第一覆盖增强等级分配覆盖增强资源。
可选地, 第一覆盖增强等级的第一序列与其他覆盖增强等级的序列不 同,则基站根据预留资源或第一序列为第一覆盖增强等级分配覆盖增强资源 具体为: 基站根据第一覆盖增强等级对应的 UE发送的第一序列, 确定第 一覆盖增强等级对应的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信需求为第一覆盖增强等级分配覆盖增强资源。
可选地, 第一覆盖增强等级对应的 UE的发送的第一序列的次数与其 他覆盖增强等级对应的 UE发送的序列次数不同; 则基站根据预留资源或 第一序列为第一覆盖增强等级分配覆盖增强资源具体为:基站根据第一覆盖 增强等级对应的 UE发送的第一序列的次数, 确定第一覆盖增强等级对应 的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信需求为第 一覆盖增强等级分配覆盖增强资源。
本实施例提供的方法, 当基站没有为第一覆盖增强等级对应的 UE分 配覆盖增强资源时, 基站通过检测在预留资源上是否有第一覆盖增强等级 对应的 UE发送的第一序列检测 UE是否有通信需求, 若是, 则根据预留 资源和 /或第一序列确定 UE的通信需求, 并根据 UE的通信需求为第一覆 盖增强等级分配覆盖增强资源。 本实施例提供的方法, 能够根据第一覆盖 增强等级对应的 UE的实际通信需求, 为第一覆盖增强等级分配覆盖增强 资源, 提高了资源的利用率。
本实施例中, 基站能够根据第一覆盖增强等级对应的 UE使用的预留 资源和 /或第一序列确定发送通信需求的 UE的第一覆盖增强等级的级别, 如确定出发送通信需求的 UE的覆盖增强级别为 CI_level3,则为 CI_level3 分配对应覆盖增强资源和使用相应的覆盖增强技术。在本发明一种可能的 实现方式中, 如果各覆盖增强等级对应的 UE都使用相同的预留资源和第 一序列, 则基站无法根据 UE的预留资源和第一序列判断出该 UE对应的 覆盖增强等级, 基站只能确定出该 UE有通信需求, 但无法确定 UE对应 的覆盖增强等级, 则基站按照覆盖增强等级的级别由低到高依次调整, 例 如对于 CI_level3对应的 UE, 由于基站无法确定出该 UE对应的覆盖增强 等级的级别, 则可先将当前支持的最高覆盖增强等级调高一个等级, 如果 不能满足 UE的通信需求, 则再调高一个等级, 仍不能满足要求, 继续调 整直到满足 UE的通信需求或者达到基站所能支持的最高覆盖增强等级。 当然, 基站也可以一次调高两个等级等, 或者基站选择直接把所支持的覆 盖增强等级调整到所能支持的最高覆盖增强等级, 本发明不做限制

若基站为第一覆盖增强等级预先分配了覆盖增强资源, 则第一覆盖增 强等级对应的 UE向基站反馈自身的通信需求具体为: 第一覆盖增强等级 对应的 UE 使用为第一覆盖增强等级分配的覆盖增强资源与基站进行通 信。 若基站在检测周期内检测到第一覆盖增强等级对应的 UE在使用该覆 盖增强资源, 则基站保持或增加为第一覆盖增强等级分配的覆盖增强资 源, 若第一覆盖增强等级对应的 UE在检测周期内没有使用该覆盖增强资 源, 则基站取消或减少为第一覆盖增强等级分配的覆盖增强资源。 其中, 基站为第一覆盖增强等级分配的覆盖增强资源包括随机接入资源, 第一覆 盖增强等级对应的 UE使用为第一覆盖增强等级分配的覆盖增强资源进行 通信, 具体为第一覆盖增强等级对应的 UE使用为第一覆盖增强等级分配 的随机接入资源发起随机接入过程。
若基站没有为第一覆盖增强等级预先分配覆盖增强资源, 则第一覆盖 增强等级对应的 UE向基站反馈自身的通信需求, 具体为: 第一覆盖增强 等级对应的 UE使用预留资源向基站发送第一序列, 其中, 预留资源和第 一序列为基站预留给第一覆盖增强等级的, 一种实现方式中, 该预留资源 和第一序列可以专用于 UE向基站通知自己的通信需求; 另一种实现方式 中, 该预留资源和第一序列不仅用于 UE向基站通知自己的通信需求, 而 且 UE可以使用该预留资源和第一序列继续完成随机接入过程。
UE 还可以利用本实施例提供的方法, 告知基站其通信需求, 以使基 站检测服务范围内有覆盖增强需求的 UE存在, 具体地, 基站如何检测其 服务范围内是否存在有覆盖增强需求的 UE, 可参照实施例一的描述, 这 里不在赘述。

步骤 402、 第一覆盖增强等级对应的 UE使用预留资源向基站发送第 一序列, 以使基站根据预留资源和 /或第一序列确定 UE的通信需求, 并为 第一覆盖增强等级分配覆盖增强资源。
其中, 预留资源和第一序列为基站预留给第一覆盖增强等级的, 当基 站没有为第一覆盖增强等级分配覆盖增强资源, 且第一覆盖增强等级对应 的 UE有通信需求的时候, UE使用该预留资源向基站发送第一序列, 通 知基站自己的通信需求, 其中, 各覆盖增强等级对应的 UE的预留资源或 者第一序列不同, 基站根据预留资源或第一序列确定 UE的通信需求, 为 UE分配相应的覆盖增强资源。

当第一覆盖增强等级对应的用户设备 UE有通信需求时, 向基站反馈 用户设备的通信需求, 以使基站根据第一覆盖增强等级对应的 UE的通信 需求调整为第一覆盖增强等级分配的覆盖增强资源; 并根据基站为第一覆 盖增强等级分配覆盖增强资源与基站通信。
若基站为第一覆盖增强等级预先分配了覆盖增强资源, 则处理器 21 具体用于: 使用为第一覆盖增强等级分配的覆盖增强资源与基站进行通 信。 其中, 基站为第一覆盖增强等级分配的覆盖增强资源包括随机接入资 源, 处理器 21 具体用于: 使用为第一覆盖增强等级分配的随机接入资源 发起随机接入过程。
本实施例提供的用户设备 200还包括发射器 23,若基站没有为第一覆 盖增强等级预先分配覆盖增强资源, 则处理器 21控制发射器 23使用预留 资源向基站发送第一序列,以使基站根据预留资源和 /或第一序列确定第一 覆盖增强等级对应的 UE的通信需求, 并为第一覆盖增强等级分配覆盖增 强资源。
本实施例中, 处理器 21 还用于确定分配给第一覆盖增强等级的预留 资源和第一序列。 具体地, 处理器 21 通过预定义的方式确定分配给第一 覆盖增强等级的预留资源。 进一步地, 本实施例提供的用户设备 200还包 括接收器 24, 用户设备可通过接收器 24接收基站发送的预留资源的配置 信息, 然后, 处理器 21 根据预留资源的配置信息确定预留资源。 当处理 器 21通过预定义的方式确定预留资源时, 具体地, 处理器 21根据预定的 周期和帧号确定预留资源, 其中, 帧号是无线帧号或者子帧号。
本实施例中, 处理器 21 还用于通过预定义的方式确定分配给第一覆 盖增强等级的第一序列。 或者, 接收器 24接收基站发送的第一序列的配 置信息, 然后, 处理器 21根据第一序列的配置信息确定第一序列。
本实施例中, 预留资源为第二覆盖增强等级对应的时频资源中的预留 时频资源。 第一序列为第二覆盖增强等级对应的预留序列中的第二序列。 或者, 第一序列为第二覆盖增强等级对应的预留序列中的第二序列经过变 换后的序列。 其中, 第二覆盖增强等级的级别高于第一覆盖增强等级。
可选地, 第一覆盖增强等级的预留资源与其他覆盖增强等级的预留资 源不同, 以使基站根据第一覆盖增强等级的预留资源, 确定第一覆盖增强 等级对应的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信 需求为第一覆盖增强等级分配覆盖增强资源。
可选地, 第一覆盖增强等级的第一序列与其他覆盖增强等级的序列不 同, 以使基站根据第一覆盖增强等级对应的 UE发送的第一序列, 确定第 一覆盖增强等级对应的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信需求为第一覆盖增强等级分配覆盖增强资源。
可选地, 第一覆盖增强等级对应的 UE的发送的第一序列的个数与其 他覆盖增强等级对应的 UE发送的序列个数不同, 以使基站根据第一覆盖 增强等级对应的 UE发送的第一序列的个数, 确定第一覆盖增强等级对应 的 UE的通信需求, 并根据第一覆盖增强等级对应的 UE的通信需求为第 一覆盖增强等级分配覆盖增强资源。
