具体实施方式
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。
本发明实施例提供一种上行接入方法， 应用于终端， 如图 1 所 示， 包括：
步骤 101、 获取上行业务数据。
所述上行业务可以是语音业务或者数据业务， 则该终端可以获 取到语音上行业务数据或数据上行业务数据。
需要说明的是， 在终端获取上行业务数据之前， 首先， 向基站 发送随机接入信息， 所述随机接入信息可以包括所述终端的上行时 钟信息， 以便于所述基站根据所述上行时钟信息生成上行时钟调整 信息， 然后， 接收所述基站发送的所述上行时钟调整信息， 根据所 述上行时钟调整信, I,调整所述终端的时钟信息。
步骤 102、 从预设的码本集中获取第一码本。
当终端判断上行业务数据的数据量小于预设数据量阈值时， 从 自身预设的码本集中获取第一码本。 需要说明的是， 所述第一码本 可以为该终端从预设的码本集中随机选择获取的码本， 且该终端预 设的码本集与基站预设的码本集相同。 当上行业务是语音业务时， 所述上行业务数据为语音上行业务数据， 所述预设数据量阈值为所 述终端预先设置的语音业务的最大上行业务数据的相应的数据量阈 值； 当上行业务是数据业务时， 所述上行业务数据为数据上行业务 数据， 所述预设数据量阈值为所述终端预先设置的数据业务的最大 上行业务数据的相应的数据量阈值。
步骤 103、 根据所述第一码本， 以及码本与导频序列的映射关 系， 获取所述第一码本对应的第一导频序列。
所述码本与导频序列的映射关系可以直接为码本与导频序列的 映射关系， 也可以为码本与导频序列子集合的映射关系； 其中， 每 个码本对应一个导频序列子集合， 每个所述导频序列子集合包括至 少一个导频序列， 任意两个码本对应的导频序列子集合中不存在相 同的导频序列。
步骤 104、 根据所述第一码本及所述上行业务数据生成上行数 据信号。
该终端根据所述第一码本将所述上行业务数据映射成数据调制 符号， 再将所述数据调制符号通过乘以载波信号生成上行数据信 号， 变换到高频用于射频发送。
步骤 105、 生成所述第一导频序列对应的导频信号。 将所述第一导频序列进行调制生成导频信号。 所述调制
( modulation )就是对信号源的信息进行处理加到载波上， 使其变为 适合于信道传输的形式的过程， 就是使载波随信号而改变的技术。
步骤 106、 向基站发送所述上行数据信号和所述导频信号。 该终端根据所述第一码本及所述上行业务数据生成上行数据信 号， 生成所述第一导频序列对应的导频信号后， 在上行数据资源块 的位置向基站发送所述上行数据信号， 所述导频信号可以插入上行 数据资源块的位置随所述上行数据信号一起向基站发送。
这样一来， 终端可以直接从自身预设的码本集中获取第一码 本， 并根据所述第一码本， 以及码本与导频序列的映射关系来获取 该第一码本对应的第一导频序列， 并相应生成上行数据信号和导频 信号， 在向基站发送所述上行数据信号和所述导频信号之前， 无需 与基站进行交互以生成上行数据信号和导频信号， 因此减少了终端 与基站之间信息的交互过程， 特别在上行业务数据的数据量较小 时， 有效解决了因需要和基站进行交互以生成上行数据信号和导频 信号而造成资源浪费的问题。
与上一实施例对应， 本发明实施例提供一种上行接入方法， 应 用于基站， 包括：
步骤 201、 接收终端发送的上行数据信号和导频信号。
所述导频信号为终端根据第一导频序列对应生成的， 所述第一 导频序列是所述终端根据从自身预设的码本集中获取的第一码本， 以及码本与导频序列的映射关系， 获取的与所述第一码本对应的导 频序列。 所述上行数据信号为所述终端根据所述第一码本及所述终 端获取的上行业务数据生成的。
所述终端从自身预设的码本集中获取的第一码本是在所述上行 业务数据的数据量小于预设数据量阈值时， 从所述预设的码本集中 获取的。 所述码本与导频序列的映射关系可以直接为码本与导频序 列的映射关系， 也可以为码本与导频序列子集合的映射关系， 其 中， 每个码本对应一个导频序列子集合， 每个所述导频序列子集合 包括至少一个导频序列， 任意两个码本对应的导频序列子集合中不 存在相同的导频序列。
需要说明的是， 在接收终端发送的上行数据信号和导频信号之 前， 先接收终端发送的随机接入信息， 所述随机接入信息包括终端 的上行时钟信息， 根据所述上行时钟信息生成上行时钟调整信息， 向所述终端发送所述上行时钟调整信息， 以便于所述终端根据所述 上行时钟调整信, I.调整所述终端的时钟信息。
这样一来， 基站接收终端发送的上行数据信号和导频信号， 所 述上行数据信号为所述终端根据所述第一码本及所述终端获取的上 行业务数据生成的， 所述导频信号为所述终端根据所述第一码本对 应的第一导频序列对应生成的， 相对于现有技术， 在接收终端发送 的上行数据信号和导频信号之前， 终端无需与基站进行交互以生成 上行数据信号和导频信号， 因此减少了终端与基站之间信息的交互 过程， 特别在上行业务数据的数据量较小时， 有效解决了因需要和 基站进行交互以生成上行数据信号和导频信号而造成资源浪费的问 题。
本发明实施例提供一种上行接入方法， 应用于终端和基站， 如 图 2所示， 包括：
步骤 301、 终端进行上行接入初始化。
如图 3所示， 步骤 301具体包括以下步骤：
步骤 301 1、 基站向终端广播广播消息。
终端向基站发送上行数据信号之前， 首先需要进行上行接入初 始化。 具体的， 基站向终端广播广播消息， 所述广播消息包括终端 进行小区驻留和上行业务通信时所使用的小区的小区地址、 根序列 编号、 进行上行数据信号传输时所用的时频资源、 上行数据资源块 的位置、 随机接入资源块的位置等信息。
步骤 3012、 终端根据广播消息建立码本与导频序列的映射关 系。
终端在接收到基站发送的广播消息之后， 根据广播消息中的小 区地址和根序列编号等生成至少一个导频序列， 组成一个导频序列 子集合， 该终端可以根据所述导频序列占用时频资源的资源单元位 置和循环位移参数将所述导频序列进行分组得到导频序列子集合， 使得该终端预设的码本集中的码本与导频序列形成映射关系， 所述 码本与导频序列的映射关系也可以为码本与导频序列子集合的映射 关系， 其中， 每个码本对应一个导频序列子集合， 每个所述导频序 列子集合包括至少一个导频序列， 任意两个码本对应的导频序列子 集合中不存在相同的导频序列。
步骤 3013、 终端向基站发送随机接入信息。
终端建立码本与导频序列的映射关系之后， 该终端在基站分配 的所述随机接入资源块的位置向该基站发送随机接入信息， 所述随 机接入信息包括所述终端的上行时钟信息。
需要说明的是， 所述上行时钟信息用于终端与基站之间保持时 间同步， 由于不同终端的上行业务数据调制成上行数据信号到达基 站时需要时间对齐， 以确保基站之间上行数据信号的正交性， 有助 于消除小区内的干扰。 但是， 上行数据信号在空间传输时存在延迟 的现象， 如果终端在呼叫期间向远离基站的方向移动， 则所述基站 向终端发送的下行数据信号将会越来越迟的到达该终端， 同时， 该 终端的上行数据信号也会越来越迟的到达该基站， 若上行数据信号 或下行数据信号延迟过长会导致基站收到的该终端在本时隙上的上 行数据信号与基站收下一个终端的上行数据信号的时隙相互重叠， 引起码间干扰。 因此， 该终端需要向基站发送上行时钟信息， 再根 据基站向该终端发送的上行时钟调整信息调整该终端的上行时钟， 以便于该终端发送上行数据时该终端与基站之间保持同步。 步骤 3014、 基站根据所述随机接入信息生成上行时钟调整信 息。
基站在与终端对应的随机接入资源块的位置接收所述随机接入 信息之后， 根据所述随机接入信息生成上行时钟调整信息， 所述随 机接入信息包括所述终端的上行时钟信息。
步骤 3015、 基站向该终端发送所述上行时钟调整信息。
步骤 3016、 终端根据上行时钟调整信息调整终端的时钟信 息。
该终端在基站分配的所述随机接入资源块的位置接收所述上行 时钟调整信息， 根据所述上行时钟调整信息调整该终端的时钟与基 站建立同步， 使得该终端与基站之间进行上行数据信号传输。
步骤 302、 终端获取上行业务数据。
用户可以对终端进行操作来实现语音业务或者数据业务。 具体 的， 用户可以触发该终端的用户界面显示的键盘， 输入被叫用户信 息， 触发拨号键， 该终端接收该触发信号， 获取到语音上行业务数 据， 向基站发送呼叫请求； 用户还可以用该终端上网浏览网页等， 则该终端获取到数据上行业务数据， 向基站发出数据请求。
步骤 303、 终端进行所述上行业务数据的传输。
当上行业务数据的数据量小于预设数据量阈值， 终端从自身预 设的码本集中获取第一码本， 并根据所述第一码本， 以及码本与导 频序列的映射关系来获取该第一码本对应的第一导频序列， 并相应 生成上行数据信号和导频信号， 向基站发送该上行数据信号和导频 信号。 上行业务可以是语音业务或数据业务， 当上行业务是语音业 务时， 所述上行业务数据为语音上行业务数据， 所述预设数据量阈 值为所述终端预先设置的语音业务的最大上行业务数据的相应的数 据量阈值， 当上行业务为数据业务时， 所述上行业务数据为数据上 行业务数据， 所述预设数据量阈值为所述终端预先设置的数据业务 的最大上行业务数据的相应的数据量阈值。
如图 4所示， 步骤 303具体包括以下步骤：
步骤 303 1、 当上行业务数据的数据量小于预设数据量阈值时， 终端从自身预设的码本集中获取第一码本。
终端从预设的码本集中可以随机选择获取第一码本， 且与基站 预设的码本集相同。 所述码本集中的码本可以用 比特进行编 码， 所述 K为存在的终端数量， 所述 K为大于或等于 1 的整数。
步骤 3032、 终端根据所述第一码本， 以及码本与导频序列的 映射关系， 获取所述第一码本对应的第一导频序列。
所述码本与导频序列的映射关系可以直接为码本与导频序列的 映射关系， 也可以为码本与导频序列子集合的映射关系， 其中， 每 个码本对应一个导频序列子集合， 每个所述导频序列子集合包括至 少一个导频序列， 任意两个码本对应的导频序列子集合中不存在相 同的导频序列。 具体的， 所述终端预设的码本集包括至少一个码 本， 每个所述码本对应一个导频序列子集合， 每个所述导频序列子 集合包括至少一个导频序列， 任意两个码本对应的导频序列子集合 中不存在相同的导频序列， 不同的导频序列两两正交。 该终端根据 所述第一码本以及码本与导频序列的映射关系， 获取所述第一码本 对应的第一导频序列。 所述导频序列子集合中的导频序列可以用 g ^ 特进行编码， 所述 M为所述码本集中每个所述码本对应的导 频序列子集合中导频序列的个数， 为大于或等于 1 的整数。
步骤 3033、 终端根据第一码本将上行业务数据映射成数据调 制符号。
该终端利用随机选择获得的所述第一码本将该终端向基站发送 的上行业务数据根据调制技术映射成数据调制符号， 所述调制技术 可以是 QAM ( Quadrature Amplitude Modulation , 正交振幅调制）等 调制技术， 所述数据调制符号对应基带信号的幅度和相位， 所述基 带信号为终端发出的没有经过调制的原始电信号， 即原始电信号没 有进行频谱搬移和变换等调制的直接表达了要传输的信息的信号， 例如说话的声波就是基带信号。
假设第一码本为 SCMA(Sparse Code Multiple Access , 稀疏码 分多址）码本， 所述 SCMA是一种混合多址接入方式， 利用 SCMA 码本将该终端向基站发送的上行业务数据映射成数据调制符号， 即可以是才艮据 QAM 调制技术和 CDMA ( Code Division Multiple Access , 码分多址）技术的一种结合， 使得多个上行业务数据使用 同一个时频资源块， 每个时频资源块由若干资源单元组成。 具体 的， 首先将可用的时频资源分成若干正交的时频资源块， 每个时 频资源块含有 L个资源单元， 假设存在 k个终端， 当所述 K个终 端向基站发送上行业务数据时， 将所述上行业务数据分成 S 比特 大小的数据块， 通过查找 SCMA 码本 将每个所述数据块映射成 一组数据调制符号；^ = ^， χ^, - χ^ ) , 每个所述数据调制符号对应 时频资源块中一个资源单元。 所述 Κ为大于或等于 1 的整数， 所 述 L为大于或等于 1 的整数， 所述 X为大于或等于 1 的整数。 需要说明的是， SCMA码本通过符号 0所在位置的不同进行 区分不同的 SCMA码本。 对于 S 比特大小的数据块， 每个 SCMA 码本含有 个不同的调制符号组， 对应 种可能的数据块。 每个调 制符号组均有部分符号为 0, 同一 SCMA码本的不同调制符号组符 号 0 所在的资源单元位置相同， 且 SCMA码本满足稀疏性条件， 即调制符号组中符号 0 所占资源单元的数量大于或等于资源单元 总数的一半。 示例的， 将终端的上行业务数据划分为 2 比特大小的数据块， 则调制符号组长度为 4, 利用 QAM调制将一组数据块映射成一个数 据调制符号， 例如 4QAM将 2比特数据映射成 4星座点的数据调制 符号， 00映射成 1+i, 01映射成 1-i, 10映射成 -1+i, 11映射成 -1-i, 再根据 CDMA技术将一个数据调制符号扩展成多个数据调制符号， 例如扩频码 1001 将调制符号 1+i 扩展成 4 个调制符号， 即 l+i,-l-i,-l-i,l+i。 需要说明的是， SCMA 码本与调制符号组是对 应， 将数据块映射成多个数据调制符号。 且 SCMA码本并不是对同 一个数据调制符号的简单扩展， 而是一组预先确定的符号， 并且有 部分符号位置是 0。 不同上行业务数据使用不同的码本， 将相同的 数据块映射成不同的调制符号组。
步骤 3034、 终端根据数据调制符号生成上行数据信号。
该终端利用随机选择获得的所述第一码本将所述上行业务数据 根据调制技术映射成数据调制符号， 所述数据调制符号对应基带信 号的幅度和相位， 由于基带信号的频率较低， 本发明中该终端获取 到所述上行业务数据后向基站发送前没经过调制的信号为基带信 号， 则再通过乘以载波信号变换到高频， 生成上行数据信号， 用于 射频发送。 载波是指被调制以传输信号的波形， 通常为正弦波。 所 述载波信号是将普通信号调制到特定频率的高频信号上， 在没有加 载普通信号的高频信号时， 高频信号的波幅是固定的， 加载之后波 幅就随着普通信号的变化而变化， 即调幅， 还可以调相， 调频等。 所述普通信号为声音或图像等信号。
步骤 3035、 终端根据第一导频序列生成导频信号。
该终端根据步骤 3032 中获取到的所述第一码本对应的第一导 频序列， 生成所述第一导频序列对应的导频信号。
步骤 3036、 终端向基站发送上行数据信号和导频信号。
该终端根据所述第一码本及所述上行业务数据生成上行数据信 号， 生成所述第一导频序列对应的导频信号， 在第一接入资源块的 位置向基站发送所述上行数据信号和所述导频信号， 以便于所述基 站根据所述上行数据信号和所述导频信号获取上行业务数据。
基站接收到终端发送的上行数据信号和导频信号后， 可以进行 信道估计， 并解码得到终端的上行业务数据， 具体信号估计和解码 的过程不再详述。
当终端判断上行业务数据的数据量大于或等于预设数据量阈值 时， 终端的上行接入方式与现有方式一致， 所不同的是， 终端先向 基站发送上行资源请求消息， 基站接收到所述上行资源请求消息后， 基站从自身预设的码本集中获取第二码本； 根据所述第二码本， 以及码本 与导频序列的映射关系， 获取所述第二码本对应的第二导频序列； 并将所 述第二码本的序号及所述第二导频序列的序号发送给终端， 以便于终端根 据所述第二码本的序号从自身预设的码本集中获取第二码本， 根据所述第 二导频序列的序号获取所述第二码本对应的第二导频序列， 最后， 终端 根据所述第二码本以及所述第二导频序列， 并相应生成第二上行数 据信号和第二导频信号， 向基站发送该第二上行数据信号和第二导 频信号。 所述基站预设的码本集与终端预设的码本集相同， 所述基 站预设的导频序列子集合与所述终端预设的导频序列子集合相同。
需要说明的是， 本发明实施例提供的上行接入方法步骤的先后 顺序可以进行适当调整， 步骤也可以根据情况进行相应增减， 示例 的， 如步骤 3034和步骤 3035之间的前后顺序可以互换， 即可先生 成导频信号再生成上行数据信号， 或上行业务数据的数据量大于或 等于预设数据量阈值时， 终端向基站发送第二上行数据信号和第二 导频信号之前， 可先生成第二导频信号再生成第二上行数据信号， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻 易想到变化的方法， 都应涵盖在本发明的保护范围之内， 因此不再 赘述。
本发明实施例提供的上行接入方法， 在终端获取上行业务数据 后， 判断所述上行业务数据的数据量小于预设数据量阈值， 从所述 预设的码本集中获取第一码本， 根据所述第一码本， 以及码本与导 频序列的映射关系， 获取所述第一码本对应的第一导频序列， 根据 所述第一码本及上行业务数据生成上行数据信号， 生成所述第一导 频序列对应的导频信号， 该终端向基站发送所述上行数据信号和所 述导频信号， 然后， 基站接收到终端发送的上行数据信号和导频信 号后， 可以进行信道估计， 并解码得到终端的上行业务数据。 相对 于现有技术， 终端可以直接从自身预设的码本集中获取第一码本， 并根据所述第一码本， 以及码本与导频序列的映射关系来获取该第 一码本对应的第一导频序列， 并相应生成上行数据信号和导频信 号， 在向基站发送所述上行数据信号和所述导频信号之前， 无需与 基站进行交互以生成导频信号和上行数据信号， 因此减少了终端与 基站之间信息的交互过程， 特别在上行业务数据的数据量较小时， 有效解决了因需要和基站进行交互以生成上行数据信号和导频信号 而造成资源浪费的问题。 本发明实施例提供一种终端 70 , 如图 5所示， 包括：
第一获取单元 701 , 用于获取上行业务数据。
所述上行业务可以是语音业务或者数据业务， 则该终端可以获 取到语音上行业务数据或数据上行业务数据。 需要说明的是， 在终端获取上行业务数据之前， 首先， 向基站 发送随机接入信息， 所述随机接入信息可以包括所述终端的上行时 钟信息， 以便于所述基站根据所述上行时钟信息生成上行时钟调整 信息， 然后， 接收所述基站发送的所述上行时钟调整信息， 根据所 述上行时钟调整信, I,调整所述终端的时钟信息。
