图 1为本发明提供的同歩信号的承载方法一个实施例的流程图, 如图 1 所示, 本实施例的方法可以包括:
歩骤 101、 第一用户设备确定同歩信号的优先级参数。
歩骤 102、 第一用户设备根据优先级参数确定承载同歩信号的资源, 其 中, 资源的配置指示优先级参数。
歩骤 103、 第一用户设备使用资源, 向第二用户设备发送所述同歩信号、 以供所述第二用户设备确定所述第二用户设备的同歩信号。
可选的, 同歩信号的优先级参数具体可以包括等级和层级中的至少一个。 作为一种可行的实施方式, 同歩信号的等级可以用于标识同歩信号的来 源, 而同歩信号的来源具体可以包括全球导航卫星系统 (Global Navigation Satellite System, 以下简称: GNSS); 网络设备, 例如: 基站 (eNodeB); 所 述第一用户设备, 例如: 第一用户设备自身的时钟 (local timing) 等等。 例 如: 可以将来源于 G SS的同歩信号作为第一等级, 来源于 eNodeB的同歩
二等级, 来源于 local timmg的同歩信号作为第三等级。 其中, 可
Figure imgf000013_0001
作为另一种可行的实施方式, 同歩信号的等级还可以用于标识同歩信号 的精度,例如:小于等于 O.lppm的同歩信号可以作为第一等级;大于 O.lppm, 小于或等于 0.5ppm可以作为第二等级; 大于 0.5ppm, 小于或等于 l .Oppm可 以作为第三等级; 大于 l .Oppm可以作为第四等级。 其中, 可以设定: 第一等 级的优先级高于第二等级, 第二等级的优先级高于第三等级, 第三等级的优 先级高于第四等级, 以此类推。
以上仅以示意提供了一种可行的等级划分方式, 但并不以此对本发明实 施例造成限制。
可选的, 同歩信号的层级可以用于标识同歩信号的转发级别。 例如: 在 上述第一用户设备向第二用户设备发送同歩信号的例子中, 如果该同歩信号 为第一用户设备自身产生的同歩信号, 则该同歩信号可以作为第一层级; 如 果该同歩信号是第一用户设备依据第三用户设备产生的同歩信号而生成的, 此时, 第三用户设备向第一用户设备发出的该同歩信号作为第一层级, 而第 一用户设备向第二用户设备发送的同歩信号作为第二层级; 依次类推。其中 可以设定: 第一层级的优先级高于第二层级 第二层级的优先级高于第三层 需要说明的是, 不同优先级参数的同歩信号, 可以是等级和层级中的至 少一个不同的同歩信号。 gp, 不同优先级参数的同歩信号可以是等级不同的 同歩信号, 也可以是层级不同的同歩信号, 还可以是等级和层级均不同的同 歩信号。
本发明实施例中, 第一用户设备确定同歩信号的优先级参数后, 根据同 歩信号的不同优先级参数, 可以确定不同的资源来承载。
上述的资源可以包括时域资源、 频域资源和码字资源。 而不同的资源, 具体可以是时域、 频域和码字中至少一个不同的资源。
若承载至少两个同歩信号的时域资源、 频域资源和码字资源三者均完全 相同, 则该至少两个同歩信号可以视为相同的同歩信号。 若上述至少两个同 歩信号的三种资源不完全相同, 即至少有一种资源不同, 则上述至少两个同 歩信号被视为不同的同歩信号。
可选的, 承载同歩信号的时域资源不同, 可以包括以下至少一个: 承载 同歩信号的数据帧的序号不同, 承载同歩信号的时隙的序号不同, 承载同歩 信号的子帧的序号不同, 承载同歩信号的正交频分复用 OFDM符号的序号不 同。
可选的, 承载同歩信号的频域资源不同, 包括以下至少一个: 承载同歩 信号的 PRB的序号不同; 承载同歩信号的单个子载波的序号不同; 承载同歩 信号的子载波组内的子载波的序号不同。 其中, 对承载同歩信号的子载波组 内的子载波的序号不同做如下举例:如果两个子载波组分别包含 3个子载波, 其中一个子载波组中三个子载波的序号, 例如分别为 1, 2, 3, 另一个子载 波组中的三个子载波的序号, 例如分别为 1, 3, 4, 由于这两个子载波组中 的子载波的序号有一个不同 (2和 4为不同的序号), 就认为这两个子载波组 内的子载波的序号是不同的。 也就是说, 只要至少两个子载波组内的子载波 的序号有一个不同, 就可认为该至少两个子载波组的子载波序号不同。
可选的, 码字不同的资源, 具体可以为, 码字序列不同的资源。
第一用户设备确定同歩信号的优先级参数后, 可以进一歩确定使用何种 资源, 以及资源的配置方式来承载同歩信号, 以使接收到该同歩信号的第二 用户设备能够获知该同歩信号对应的优先级参数, 并据此确定该第二用户设 备的同歩信号。
本实施例提供的同歩信号的承载方法, 用户设备通过确定同歩信号的优 先级参数并根据优先级参数确定承载同歩信号的资源, 进一歩使用确定的资 源来发送同歩信号, 从而能够使接收同歩信号的用户设备能够根据承载同歩 信号的资源来识别不同优先级参数的同歩信号, 接收同歩信号的用户设备可 以根据优先级参数来确定同歩信号, 提高了同歩信号确定方式的灵活性。 同 时, 由于优先级参数可以为等级和层级中的至少一个, 而等级可以表示同歩 信号的来源或精度, 层级可以表示同歩信号的转发级别, 使得接收同歩信号 的用户设备可以根据同歩信号的来源、 精度或者转发级别, 来确定自身的同 歩信号, 这样的确定方式更有针对性, 使得接收同歩信号的用户设备可以选 择更合适的同歩信号。
图 2为本发明提供的同歩信号的承载方法又一个实施例的流程图, 如图 2所示, 该方法包括:
S201、 第二用户设备接收第一用户设备发送的同歩信号。
S202、 第二用户设备根据承载同歩信号的资源, 和资源与同歩信号的优 先级参数的对应关系, 确定所述优先级参数。
S203、 第二用户设备根据所述优先级参数, 确定所述第二用户设备的同 歩信号。
其中, 不同优先级参数的同歩信号, 可以通过不同的资源来承载。 g卩, 承载同歩信号的资源与同歩信号的优先级参数具有对应关系, 因此, 第二用 户设备接收到第一用户设备发送的同歩信号后, 可以根据承载该同歩信号的 资源, 以及资源与同歩信号的优先级参数的对应关系来确定该同歩信号的优 先级, 该对应关系可以由第一用户设备和第二用户设备单方或共同确定, 确 定之后, 第一用户设备和第二用户设备都可以获取该对应关系, 获取或存储 所述对应关系的方式有多种, 并不构成对本发明的限定。
可以理解, 第二用户设备确定自身的同歩信号的方式有多种, 例如可以 从所有收到的同歩信号中, 根据这些同歩信号的优先级参数选择优先级最高 的同歩信号, 作为第二用户设备的同歩信号, 也可以采取其他方式, 并不构 成对本发明的限定。 可选的, 同歩信号的优先级参数具体可以包括等级和层 级中的至少一个。
作为一种可行的实施方式, 同歩信号的等级可以用于标识同歩信号的来 源, 而同歩信号的来源具体可以包括 GNSS , 网络设备, 或上述第一用户设 备, 可以理解, 对于某一个同歩信号来说, 其来源只有一个, 而对于通信系 统中的所有同歩信号来说, 其来源可能是上述三种来源中的任意一个。 上述 来源只是一种举例, 还可以有其他来源。 具体的, 可以通过第一等级, 第二 等级, 第三等级等来区分不同的同步信号来源。 其中, 可以设定: 第一等级 的优先级高于第二等级, 第二等级的优先级高于第三等级, 以此类推。
作为另一种可行的实施方式, 同歩信号的等级还可以用于标识同歩信号 的精度, 可以按照精度高低顺序来划分同步信号的等级, 例如: 划分为第一 等级, 第二等级、 第三等级等来区分不同的同歩信号来源: 小于等于 OJ ppn 的同步信号可以作为第一等级; 大于 O. ippm, 小于或等于().5ppm可以作为 可以作为第四等级。 其中, 可以设定: 第一等级的优先级高于第二等级, 第 二等级的优先级高于第三等级, 以此类推。
关于同步信号等级具体可参见图 1所示实施例中的相关描述, 在此不再 以上仅以示意提供了一种可行的等级划分方式, 但并不以此对本发明实 施例造成限制。
可选的, 同步信号的层级可以用于标识同歩信号的转发级别。 飼如: 某 用户设备 A根据另一个用户设备 B产生的同步信号而生成同步信号, 则用户 设备 A产生的同歩信号相比用户设备 B产生的同歩信号低一个层级。 具体可 以通过第一层级, 第二层级, 第三层级等来表示不同的层级。 其中; 可以设 定: 第一层级的优先级高于第二层级 第二层级的优先级高于第三层级, 以 关于同步信号层级具体可参见图 1所示实施例中的相关描述, 在此不再 需要说明的是, 不同优先级参数的同歩信号, 可以是等级和层级中的至 少一个不同的同歩信号。 gp, 不同优先级参数的同歩信号可以是等级不同的 同歩信号, 也可以是层级不同的同歩信号, 还可以是等级和层级均不同的同 歩信号。
可选的, 承载同歩信号的资源可以包括时域资源、 频域资源和码字资源。 而不同的资源, 具体可以是时域、 频域和码字中至少一个不同的资源。
若承载至少两个同歩信号的时域资源、 频域资源和码字资源三者均完全 相同, 则该至少两个同歩信号可以视为相同的同歩信号。 若上述至少两个同 歩信号的三种资源不完全相同, 即至少有一种资源不同, 则上述至少两个同 歩信号被视为不同的同歩信号。
可选的, 承载同歩信号的时域资源不同, 可以包括以下至少一个: 承载 同歩信号的数据帧的序号不同; 承载同歩信号的时隙的序号不同; 承载同歩 信号的子帧的序号不同; 承载同歩信号的 OFDM符号的序号不同。
可选的, 承载同歩信号的频域资源不同, 包括以下至少一个: 承载同歩 信号的 PRB的序号不同; 承载同歩信号的单个子载波的序号不同; 承载同歩 信号的子载波组内的子载波的序号不同。
可选的, 码字不同的资源, 具体可以为, 码字序列不同的资源。
通信系统中可以预先设定资源与同歩信号的优先级参数的对应关系, 通 信系统中的各用户设备可以预先获知上述对应关系, 进而, 第二用户设备接 收同歩信号后, 能够根据承载同歩信号的资源以及该对应关系确定该同歩信 号的优先级。
进一歩的, 第二用户设备确定该同歩信号对应的优先级参数后, 并据此 确定该第二用户设备的同歩信号。 可选的, 若第二用户设备根据第一用户设 备发送的该同歩信号来生成同歩信号, 则第二用户设备生成的同歩信号的等 级可以与第一用户设备的同歩信号等级相同, 层级低于第一用户设备的同歩 信号一个层级。
本发明实施例提供的同歩信号的承载方法, 用户设备接收另一个用户设 备发送的同歩信号后, 通过承载同歩信号的资源, 以及资源与同歩信号的优 先级参数的对应关系确定该同歩信号的优先级参数, 并根据该优先级参数来 确定自身的同歩信号, 提高了同歩信号确定方式的灵活性。 另外, 由于优先 级参数可以为等级和层级中的至少一个, 而等级可以表示同歩信号的来源或 精度, 层级可以表示同歩信号的转发级别, 使得接收同歩信号的用户设备可 以根据同歩信号的来源、 精度或者转发级别, 来确定自身的同歩信号, 这样 的确定方式更有针对性, 使得接收同歩信号的用户设备可以选择更合适的同 歩信号。
下面采用具体的实施例, 对图 1和图 2所示方法实施例的技术方案进行 详细说明。
在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的时 域资源来区分不同优先级参数的同歩信号。
这里的发送同歩信号的时域资源, 可以是发送同歩信号的数据帧, 或者 子帧, 或者时隙, 或者正交频分复用 OFDM符号。 根据不同的时域资源区分 不同优先级参数的同歩信号, 可以通过在不同序号的数据帧, 或者不同序号 的子帧, 或者序号不同的时隙, 或者序号不同的 OFDM符号, 或者四者的任 意组合上发送同歩信号, 来区分信号不同优先级参数的同歩信号。 以下以通过不同的不同序号的子帧区分不同优先级参数的同歩信号为 例,可以理解的是,可以通过这个例子扩展到以数据帧,或者时隙,或者 OFDM 符号区分不同优先级参数的同歩信号。
如图 3所示, 假设一个数据帧中包含 10个子帧, 这 10个子帧的序号分 别为 1, 2, 3, 4, 5, 6, 7, 8, 9, 10。 其中, 一个数据帧中可以承载一个 或多个同歩序列, 这一个或多个同歩序列用来承载同一个同歩信号, 通常情 况下, 一个数据帧中可以承载 2个同歩序列, 这 2个同歩序列用来承载同一 个同歩信号, 以下也以一个数据帧中承载 2个同歩序列为例进行说明。 假设 其中这一个同歩信号的第一个同歩序列在第一个子帧中承载, 在该实施场景 下, 可以通过以下几种子帧配置来区分不同的同歩信号: {1, 2}, {1, 3}, {1, 4}, {1, 5}, 其中 {1, 2}表示一个同歩序列在第一个子帧 (即该子帧在 数据帧中的序号是 1 ) 中承载, 另一个同歩序列在第二个子帧 (即该子帧在 数据帧中的序号是 2)中承载。 {1 , 3}表示一个同歩序列在第一个子帧上承载, 另一个同歩序列在第三个子帧中承载。
上述几种不同的子帧资源配置,分别对应不同的优先级参数的同歩信号, 由于发送同歩信号的用户和接收同歩信号的用户设备都能获知 (例如: 本地 存储或者从其他设备获取) 子帧资源配置与优先级参数的对应关系, 接收该 同歩信号的用户设备, 可以根据承载该同歩信号的子帧资源, 以及子帧资源 配置与优先级参数的对应关系, 区分出不同优先级参数的同歩信号。 在实际 的系统中, 可以有确定的在上述几个时间配置中确定出需要的数量, 代表需 要数量的同歩信号优先级参数。
进一歩的, 假设数据帧中包含 N个数据子帧, N为大于 0的整数。 仍以 一个数据帧中承载 2个同歩序列为例进行说明 (这 2个同歩序列都承载了同 一个同歩信号),其中一个同歩序列在第一个子帧中承载。则在该实施场景下, 可以通过以下 ceil N/2;>-l种子帧配置方式来区分不同优先级参数的同歩信号: {1, 2}, {1, 3}, …, {1, ceil(N/2)}, Ceil()是向上取整运算。 其中 {1, 2}表 示同歩序列中的一个在第一个子帧中承载, 另一个在第二个子帧中承载。 通 过这 ceil N/2;i-l种不同的子帧资源配置, 可以区分 ceil N/2;i-l个不同优先级 参数的同歩信号。 在实际的系统中, 可以有确定的在这 ceil N/2;i-l个时间配 置中确定出需要的数量, 代表需要数量的同歩信号优先级参数。 本实施例中, 用户设备通过确定同歩信号的优先级参数, 并根据优先级 参数确定承载同歩信号的子帧资源, 进一歩使用确定的子帧资源来发送同歩 信号, 从而能够使接收同歩信号的用户设备能够根据承载同歩信号的子帧资 源来识别不同优先级参数的同歩信号, 接收同歩信号的用户设备可以根据优 先级参数来确定同歩信号, 提高了同歩信号确定方式的灵活性。 另外, 由于 优先级参数可以为等级和层级中的至少一个, 而等级可以表示同歩信号的来 源或精度, 层级可以表示同歩信号的转发级别, 使得接收同歩信号的用户设 备可以根据同歩信号的来源、 精度或者转发级别, 来确定自身的同歩信号, 这样的确定方式更有针对性, 使得接收同歩信号的用户设备可以选择更合适 的同歩信号。
在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的频 率资源来区分不同优先级参数的同歩信号。
这里的频率资源,可以是发送同歩信号所占用的频率。在长期演进(Long Term Evolution, LTE ) 系统中, 频率资源可以是物理资源块对 (Physical Resource Block, PRB pair), 也可以是 PRB pair中的单个子载波或者子载波 组。 根据不同的频率资源区分不同优先级参数的同歩信号, 即通过在不同的 序号的 PRB p r上, 或者不同序号的单个子载波上, 或者子载波组内不同序 号的子载波上, 来发送同歩信号以区分不同优先级参数的同歩信号。
以下以通过不同序号的 PRB pair区分不同优先级参数的同歩信号为例, 可以理解的是, 可以通过这个例子扩展到以不同序号的单个子载波或者子载 波组内不同序号的子载波区分不同优先级参数的同歩信号。
如图 4所示, 假设系统的带宽是 50个 PRB pair, 发送一个同歩信号需要 占用连续的 6个 PRB。 在该实施场景下, 可以区分的不同优先级参数的同歩 信号的连续 6个 PRB配置最大有 7个。通过这 7个不同的 PRB pair资源资源 配置, 可以区分 7个不同优先级参数的同歩信号。 在实际的系统中, 可以有 选择的在这 7个频率配置中确定出需要的数量, 代表需要数量的同歩信号优 先级参数。
如图 4所示, 在系统中有三个可用的物理资源 fl, £2和 β可以用来承载 系统的同歩信号。 每个物理资源上可以包括一个或多个 PRB pair, 其中, 不 同的物理资源是由不同的 PRB pair组成的, 各物理资源之间的 PRB pair可以 没有重叠, 也可以有部分重叠。 那么 fl, G和 β可以分别用于承载不同优先 级参数的同歩信号。
进一歩的, 假设数据帧中包含 Ν个 PRB pair, N为大于 0的整数, 发送 同歩信号需要占用连续的 M个 PRB pair, M为大于 0的整数。在该实施场景 下,可以区分的不同优先级参数的同歩信号的 PRB pair配置有 floor N/Μ;)个, FloorO表示向下取整运算。通这 floor N/M)种不同的频率资源配置, 可以区分 floor N/Μ;)个不同的同歩信号优先级参数。在实际的系统中, 可以有选择的在 这 floor N/Μ;)个频率配置中确定出需要的数量, 代表需要数量的同歩信号优 先级参数。
本实施例中, 用户设备通过确定同歩信号的优先级参数, 并根据优先级 参数确定承载同歩信号的 PRB pair, 进一歩使用确定的 PRB pair来发送同歩 信号, 从而能够使接收同歩信号的用户设备能够根据承载同歩信号的 PRB pair来识别不同优先级参数的同歩信号, 接收同歩信号的用户设备可以根据 优先级参数来确定同歩信号, 提高了同歩信号确定方式的灵活性。 另外, 由 于优先级参数可以为等级和层级中的至少一个, 而等级可以表示同歩信号的 来源或精度, 层级可以表示同歩信号的转发级别, 使得接收同歩信号的用户 设备可以根据同歩信号的来源、精度或者转发级别, 来确定自身的同歩信号, 这样的确定方式更有针对性, 使得接收同歩信号的用户设备可以选择更合适 的同歩信号。
在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的码 字资源来区分不同优先级参数的同歩信号。
这里的码字资源, 可以是发送同歩信号所使用的码字序列。 依靠码字序 列区分同歩信号的优先级参数, 即通过在不同码字序列上发送同歩信号区分 信号的优先级参数。 通常情况下, 一个同歩信号可以对应一个或多个同歩序 列, 一个同歩序列可以用一个或多个码字序列承载, 其中的多个码字序列可 以位于不同的符号。
假设系统的可用码字有三个, 比如, 长度为 63比特的序列:
. mm 1)
du {n) = e ] 63 n = 0,1, ...,30,31,32, ...,61,62 其中, u取值 25、 29或 34分别产生 3个不同的码字序列。 即可以通过 u 的不同取值来产生不同的码字序列, 其中 u取值 25、 29或 34得到的三个码 字序列相关特性好。
在该实施场景下, 通过这 3个不同的码字序列, 可以区分 3个不同的同 歩信号等级。 在实际的系统中, 可以有选择的在这 3个码字序列中确定出需 要的数量, 代表需要数量的同歩信号优先级参数。
如图 5所示, 一个数据帧包含 10个子帧, 这 10个子帧包含的符号数目 相同, 例如可以为 14个符号, 13个符号和 12个符号。 假设在 10个子帧中, 承载同歩信号的子帧里面, 有两个符号承载一个同歩信号, 一个符号承载一 个同歩序列, 一个同歩信号对应两个同歩序列。 例如: 如图 5所示, 在包括 14个符号的子帧中, 可以使用符号 1承载一个同歩序列, 使用符号 5承载另 一个同歩序列; 在包括 13个符号的子帧中, 可以使用符号 1承载一个同歩序 列, 使用符号 5承载另一个同歩序列; 在包括 12个符号的子帧中, 可以使用 符号 1承载一个同歩序列, 使用符号 4承载承载另一个同歩序列。 如果在一 个符号里可能的承载同歩序列的个数为 3, 那么两个符号里承载同歩序列的 不同的配置数目一共有 3*3=9种。 也就是说, 可以区分的同歩信号的优先级 参数为 9个, 进而可以区分 9个不同优先级参数。
此外, 在上面的例子中, 我们看到承载同一个同歩信号的两个承载的符 号的间距分别为 {3}, {3}和 {2}, 其中间距为 {3}表示间距是 3个符号, 如果 间距为 {0}, 表示这两个符号相邻, 中间没有间隔其他符号。 在实际系统中, 如果符号数目为 14个, 根据系统的需要, 承载同一个同歩信号的两个承载的 符号的间距可以为 {0}, {1 }, {2}, {3}, {4}, {5}, {6}, {7}, {8}, {9}, {10}, {11 }, {12}中的任意一个值。
再如图 6所示, 一个数据帧包含 10个子帧, 这 10个子帧包含的符号数 目相同, 例如可以为 14个符号, 13个符号和 12个符号。 在 10个子帧中, 承载同歩信号的子帧里面, 有三个符号承载一个同歩信号, 每个符号用于承 载一个同歩序列, 也就是说, 一个同歩信号对应三个同歩序列。 例如: 如图 6所示, 在包括 14个符号的子帧中, 可以使用符号 1承载一个同歩序列, 使 用符号 7承载另一个同歩序列, 符号 13承载又一个同歩序列; 在包括 13个 符号的子帧中, 可以使用符号 1承载一个同歩序列, 使用符号 5承载另一个 同歩序列, 符号 13承载又一个同歩序列; 在包括 12个符号的子帧中, 可以 使用符号 1承载一个同歩序列, 使用符号 6承载另一个同歩序列, 符号 11承 载又一个同歩序列; 如果在一个符号里可能的承载同歩序列的个数为 3, 那 么两个符号里承载同歩序列的不同的配置数目一共有 3*3*3=27 种。 也就是 说, 可以区分的同歩信号为 27个, 进而可以区分 27个不同的优先级参数。
此外, 在上面的例子中, 我们看到承载同一个同歩信号的两个承载的符 号的间距分别为 {5}, {5}和 {4}, 其中间距为 {5}表示间距是 5个符号, 如果 间距为 {0}, 表示这两个符号相邻, 中间没有间隔其他符号。 在实际系统中, 如果符号数目为 14个, 根据系统的需要, 承载同一个同歩信号的两个承载的 符号的间距可以为 {0}, {1 }, {2}, {3}, {4}, {5}, {6}, {7}, {8}, {9}, {10}, {11 }, {12}中的任意一个。
进一歩的,假设系统的可用码字序列有 N个,通这 N个不同的码字序列, 可以区分 N个不同的同歩信号优先级参数。 在实际的系统中, 可以有选择的 在这 N个码字序列配置中确定出需要的数量, 代表需要数量的同歩信号优先 级参数。
本实施例中, 用户设备通过确定同歩信号的优先级参数, 并根据优先级 参数确定承载同歩信号的码字序列, 进一歩使用确定的码字序列来发送同歩 信号, 从而能够使接收同歩信号的用户设备能够根据承载同歩信号的码字序 列来识别不同优先级参数的同歩信号, 接收同歩信号的用户设备可以根据优 先级参数来选择同歩信号, 提高了同歩信号确定方式的灵活性。 由于优先级 参数可以为等级和层级中的至少一个, 而等级可以表示同歩信号的来源或精 度, 层级可以表示同歩信号的转发级别, 使得接收同歩信号的用户设备可以 根据同歩信号的来源、 精度或者转发级别, 来确定自身的同歩信号, 这样的 确定方式更有针对性, 使得接收同歩信号的用户设备可以选择更合适的同歩 信号。
在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的时 域资源和频域资源来区分不同优先级参数的同歩信号。
这里的时间资源, 可以是发送同歩信号的数据帧, 或者子帧, 或者时隙, 或者 OFDM符号。 这里的频率资源, 可以是发送同歩信号所占用的频率。 在 LTE系统中, 频率资源可以是 PRB pair, 也可以是 PRB pari中的单个子载波 或者子载波组。 根据时间资源和频率资源区分同歩信号的优先级参数, 就是 通过在不同序号的数据帧, 或者在数据帧中不同序号的子帧, 或者序号不同 的时隙, 或者序号不同的 OFDM符号上, 使用不同序号的 PRB, 或者不同序 号的单个子载波, 或者子载波组内不同序号的子载波上, 发送同歩信号来区 分同歩信号的优先级参数。
我们以通过在数据帧中不同序号的子帧和不同序号的 PRB pair区分不同 优先级参数的同歩信号为例, 可以通过这个例子扩展到以不同序号的数据帧 或者不同序号的 OFDM符号,与 PRB pair中的单个子载波或者子载波组区分 同歩信号的优先级参数。
假设系统的数据帧中包含 10个子帧;并假定在一个数据帧中承载 2个同 歩序列, 这 2个同歩序列承载的是同一个同歩信号, 其中一个同歩序列在第 一个子帧中承载或在第六个子帧中承载; 并假定系统由两个不同的 PRB配置 来承载同歩信号, 例如: 第一种 PRB配置包括第 1个到第 6个 PRB pair, 第 二种 PRB配置包括第 7个到第 12个 PRB pair。 在前 5个子帧中, 使用第一 种 PRB配置承载同歩信号, 在后 5个子帧中, 使用第二种 PRB配置承载同 歩信号。 在该实施场景下, 可以区分的承载同歩信号的子帧和 PRB配置有以 下 17种组合 {l(fl), 2(fl)}, {l(fl), 3(fl)}, {l(fl), 4(fl)}, {l(fl), 5(fl)}, {6(f2, 7(f2)}, {6(f2), 8(G)}, {6(f2), 9(f2)}, {6(f2), 10(G)}, {l(fl), 6(f2)}, {l(fl), 7(f2)}, {l(fl), 8(G)}, {l(fl), 9(f2)}, {l(fl), 10(f2)}, {2(fl), 6(G)}, {3(fl), 6(G)}, {4(fl), 6(f2)}, {5(fl), 6(f2)}, 其中 {l(fl), 2(fl)}表示同歩 信号在第一个子帧中使用第一种 PRB配置承载, 在第二个子帧中使用第一种 PRB配置承载, {l(fl), 6(f2)}表示同歩信号在第一个子帧中使用第一种 PRB 配置承载, 在第六个子帧中使用第二种 PRB配置承载。 通过这 17种不同的 子帧资源和 PRB pair资源的配置,可以区分 17个不同的同歩信号优先级参数。 在实际的系统中, 可以有选择的在这 17个时间配置中确定出需要的数量, 代 表需要数量的同歩信号优先级参数。 可以理解, 上述 17种配置, 都选择了子 帧中的第一个 PRB , 实际确定时, 也不一定必须选择每个子帧中的第一个 PRB, 此时可以获得的资源配置数目大于 17。
进一歩的, 假设系统的数据帧中包含 2*N个子帧, 并假定在一个数据帧 中, 一共承载 2个同歩序列, 这 2个同歩序列承载的是同一个同歩信号, 其 中一个同歩序列在第一个子帧中承载或在第 N+1个子帧中承载, N为大于 0 的整数; 并假定系统由两种不同的 PRB配置用来承载同歩信号,在前 N个子 帧中, 使用第一种 PRB配置承载同歩信号, 在后 N个子帧中, 使用第二种 PRB配置承载同歩信号。 在这种条件下, 可以区分的承载同歩信号的子帧和 PRB配置有 4*N-3种。通过这 4*N-3种不同的子帧资源和 PRB资源配置,可 以区分 4*N-3个不同的同歩信号优先级参数。 在实际的系统中, 可以有选择 的在这 4*N-3个时间配置中确定出需要的数量, 代表需要数量的同歩信号优 先级参数。
本实施例中, 用户设备通过确定同歩信号的优先级参数, 并根据优先级 参数确定承载同歩信号的子帧和 PRB pair,进一歩使用确定的子帧和 PRB pair 来发送同歩信号, 从而能够使接收同歩信号的用户设备能够根据承载同歩信 号的子帧和 PRB pair来识别不同优先级参数的同歩信号, 接收同歩信号的用 户设备可以根据优先级参数来确定同歩信号, 提高了同歩信号确定方式的灵 活性。 由于优先级参数可以为等级和层级中的至少一个, 而等级可以表示同 歩信号的来源或精度, 层级可以表示同歩信号的转发级别, 使得接收同歩信 号的用户设备可以根据同歩信号的来源、 精度或者转发级别, 来确定自身的 同歩信号, 这样的确定方式更有针对性, 使得接收同歩信号的用户设备可以 选择更合适的同歩信号。
在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的时 域资源和码字资源来区分不同优先级参数的同歩信号。
这里的时域资源, 可以是发送同歩信号的数据帧, 或者子帧, 或者时隙, 或者正交频分复用 OFDM符号。根据不同的时域资源区分不同优先级参数的 同歩信号, 即通过在不同序号的数据帧, 或者在不同序号的子帧, 或者在不 同序号的时隙, 或者在不同序号的 OFDM符号, 或者四者的任意组合上发送 同歩信号, 来区分信号不同优先级参数的同歩信号。 这里的码字资源, 是指 发送同歩信号所使用的码字序列。 依靠时间资源和码字资源区分信号的优先 级参数, 就是通过在不同序号的数据帧, 或者不同序号的子帧, 或者不同序 号的 OFDM符号上, 使用不同的码字序列, 发送同歩信号区分信号的优先级 参数。
我们以子帧和码字序列区分同歩信号的优先级参数为例, 可以通过这个 例子方便的扩展到以数据帧或者 OFDM符号和码字区分同歩信号的优先级参 数。 假设系统的数据帧中包含 10个子帧;并假定在一个数据帧中,一共承载 2个同歩序列, 这 2个同歩序列承载的是同一个同歩信号, 其中一个同歩序 列在第一个子帧中承载或在第六个子帧中承载; 假定系统由两个不同的码字 序列用来承载同歩序列, 在前 5个子帧中, 使用第一个码字序列承载同歩信 号, 在后 5个子帧中, 使用第二个码字序列承载同歩信号。 在这种条件下, 可以区分的承载同歩信号的子帧和码字序列有以下 17种组合 {l(sl), 2(sl)} , {l(sl), 3(sl)}, {l(sl), 4(sl)}, {l(sl), 5(sl)}, {6(s2, 7(s2)}, {6(s2), 8(s2)}, {6(s2), 9(s2)}, {6(s2), 10(s2)}, { l(sl), 6(s2)}, {l(sl), 7(s2)}, {l(sl), 8(s2)}, {l(sl), 9(s2)}, {l(sl), 10(s2)}, {2(sl), 6(s2)}, {3(sl), 6(s2)}, {4(sl), 6(s2)}, {5(sl), 6(s2)}, 其中 {l(sl), 2(sl)}表示同歩信号在第一个子帧中使用第一个 码字序列承载, 在第二个子帧中使用第一个码字序列承载, { l(sl), 6(S2 表 示同歩信号在第一个子帧中使用第一个码字序列承载, 在第六个子帧中使用 第二个码字序列承载。通过这 17种不同的子帧资源和码字序列配置, 可以区 分 17 个不同的同歩信号优先级参数。 在实际的系统中, 可以有选择的在这 17个时间配置中确定出需要的数量, 代表需要数量的同歩信号优先级参数。
进一歩的, 假设系统的数据帧中包含 2*N个子帧, 并假定在一个数据帧 中, 一共承载 2个同歩序列, 这 2个同歩序列承载的是同一个同歩信号, 其 中一个同歩序列在第一个子帧中承载或在第 N+1个子帧中承载; 并假定系统 由两个不同的码字序列用来承载同歩序列, 在前 N个子帧中, 使用第一个码 字序列承载一个同歩序列, 在后 N个子帧中, 使用第二个码字序列承载另一 个同歩序列。 在这种条件下, 可以区分的承载同歩信号的子帧和码字序列配 置有 4*N-3种。 通过这 4*N-3种不同的子帧资源和码字序列配置, 可以区分 4*N-3 个不同的同歩信号优先级参数。 在实际的系统中, 可以有确定的在这 4*N-3 个时间配置和码字配置中确定出需要的数量, 代表需要数量的同歩信 号优先级参数。

在本发明提供的同歩信号的承载方法一个实施例中, 可以通过不同的时 间资源和码字资源来区分不同优先级参数的同歩信号。
这里的时间资源和码字资源的具体描述可参见上述各实施例中的相关描 述, 在此不再赘述。
我们以子帧和码字序列区分同歩信号的优先级参数为例,可以通过这个例 子方便的扩展到以数据帧或者 OFDM符号和码字序列区分同歩信号的优先级 参数。
假设系统的数据帧中包含 10个子帧; 并假定在一个数据帧中, 一共承载 2 个同歩序列, 这两个同歩序列对应一个同歩信号, 其中一个同歩序列在第 一个子帧中承载或在第六个子帧中承载; 并假定系统由两个不同的码字序列 分别用来承载两个同歩序列, 在前 5个子帧中, 使用第一个码字序列承载一 个同歩序列, 在后 5个子帧中, 使用第二个码字序列承载另一个同歩序列。 在这种条件下,可以区分的承载同歩信号的子帧和码字序列有以下 17种组合 {l(sl), 2(sl)}, {l(sl), 3(sl)}, {l(sl), 4(sl)}, {l(sl), 5(sl)}, {6(s2, 7(s2)}, {6(s2), 8(s2)}, {6(s2), 9(s2)}, {6(s2), 10(s2)}, {l(sl), 6(s2)}, {l(sl), 7(s2)}, {l(sl), 8(s2)}, {l(sl), 9(s2)}, {l(sl), 10(s2)}, {2(sl), 6(s2)}, {3(sl), 6(s2)}, {4(sl), 6(s2)}, {5(sl), 6(s2)}, 其中 { l(sl), 2(sl)}表示同歩信号在第一个子 帧中使用第一个码字序列承载, 在第二个子帧中使用第一个码字序列承载; {l(sl), 6(s2)}表示同歩信号在第一个子帧中使用第一个码字序列承载, 在第 六个子帧中使用第二个码字序列承载。通过这 17种不同的时间资源和频率资 源配置, 可以区分 17个不同的同歩信号优先级参数。 在实际的系统中, 可以 有确定的在这 17个时间配置中确定出需要的数量,代表需要数量的同歩信号 优先级参数。
