在 LTE版本 12及以后的版本中,会引入新载波类型( New Carrier Type, 筒称 NCT ) 。 该 NCT可以为非后向兼容载波, 该非后向兼容载波上需依赖 DMRS进行解调,因而如果采用后向兼容载波上的方法不在携带 PSS/SSS的 PRB上发送 DMRS, 则会大大降低频谱使用效率。 因而 NCT载波上需解决 PSS/SSS与 DMRS碰撞问题。 目前的解决方法是设计新的 PSS/SSS时域位 置, 使其不与 DMRS沖突。 但是这样会引起如下问题: 对版本 12 的用户设 备而言,其在初始接入时不知道接入的载波是后向兼容载波还是非后向兼容 载波, 因而其需盲检多套 PSS/SSS的位置, 使得用户设备的实现复杂。 类似 地, 在其它一些与载波属性相关的应用上, 也会由于用户设备无法合适地得 到载波属性而使得用户设备的实现复杂度较高。 发明内容

为了更清楚地说明本发明实施例的技术方案, 下面将对实施例或现有技 术描述中所需要使用的附图作筒单地介绍, 显而易见地, 下面描述中的附图 仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造 性劳动的前提下, 还可以根据这些附图获得其他的附图。

图 8是根据本发明另一例的基站的示意性框图。 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做出创 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。
应理解, 当本发明提及"第一"、 "第二,,、 "第三,,、 "第四,,、 第五和第六 等序数词时, 除非根据上下文其确实表达顺序之意, 应当理解为仅仅是起区 分之用。
本发明实施例中的载波也可称为服务小区( serving cell ),但此处的服务 小区与传统意义上的物理小区稍有差别, 不同的载波可以属于一个物理小 区。
除了上述用户设备实现复杂的问题, 对版本 12 的用户设备而言, 初始 接入时, 如果新的 PSS/SSS的位置只是时域符号上平移, 则还需要确定小区 特定参考信号 (Cell-specific Reference Signal, 筒称 "CRS" )和 PSS/SSS的 相对位置, 而使用户设备实现复杂化, 且检测性能不一定能保障, 不能阻拦 版本 11以前的老用户设备的尝试接入。
图 1是根据本发明实施例的信息传输方法 100的示意性流程图。 图 1的 实施例由用户设备执行。 如图 1所示, 该方法 100可以包括:
S110, 检测同步信号, 确定该同步信号使用的序列;
S120,根据该同步信号使用的序列确定承载该同步信号的载波的载波属 性。
具体地说,在小区搜索过程中, 或者进行无线资源管理(Radio Resource Management, 筒称 RRM )测量时, 用户设备可以检测基站发送的同步信号, 并确定该同步信号使用的序列, 然后, 可以根据该同步信号使用的序列而确 定承载该同步信号的载波的载波属性, 从而, 可以根据确定的载波属性进行 后续处理, 例如, 确定 PSS/SSS位置等。 其中, 用户设备可以通过检测主同 步信号, 确定该主同步信号使用的序列, 并根据该主同步信号使用的序列确 定承载该主同步信号的载波的载波属性; 用户设备也可以通过检测辅同步信 号, 确定该辅同步信号使用的序列, 并根据该辅同步信号使用的序列确定承 载该辅同步信号的载波的载波属性; 当然, 用户设备也可以通过检测主同步 信号和辅同步信号, 并确定该主同步信号使用的序列以及该辅同步信号使用 的序列, 并根据该主同步信号使用的序列以及该辅同步信号使用的序列共同 确定承载该主同步信号和辅同步信号的载波的载波属性。
在本发明实施例中, 可以通过非相干检测来检测主同步信号, 即可以做 最大似然检测来检测主同步信号; 可以通过相干检测和非相干检测来检测辅 同步信号, 若采用相干检测来检测辅同步信号, 则用户设备需要先通过检测 主同步信号来获得信道信息, 再利用信道信息对辅同步信号进行检测。
因此, 在本发明实施例中, 通过检测同步信号, 确定该同步信号使用的 序列, 根据该同步信号使用的序列确定承载该同步信号的载波的载波属性, 从而筒化了用户设备的实现复杂度。
在本发明实施例中, 载波属性可以包括载波类型、 双工方式、 系统带宽 和小区类型中的至少一种。
在本发明实施例中, 不同的载波属性对应于不同的序列。 即, 对于载波 类型而言, 不同的载波类型可以对应于不同的序列, 也就是说, 通过同步信 号使用的序列, 就可以直接确定载波的具体类型, 例如, 新载波类型或者后 向兼容载波;对于双工方式而言,不同的双工方式可以对应于的不同的序列, 也就是说,通过同步信号使用的序列,就可以直接确定载波的具体双工方式, 例如, 频分双工或时分双工; 对于系统带宽而言, 不同的系统带宽对应于不 同的序列, 也就是说, 通过同步信号使用的序列, 就可以直接确定载波对应 的具体系统带宽; 对于小区类型而言, 不同的小区类型对应于不同的序列, 也就是说,通过同步信号使用的序列,就可以直接确定载波对应的小区类型。 应理解, 在本发明实施例中, 通过同步信号使用的序列, 也可以直接确定载 波类型、 双工方式、 系统带宽和小区类型中的至少两种。 从而, 本发明实施 例中,可以根据该同步信号使用的序列直接确定承载该同步信号的载波的载 波属性。
在本发明实施例中, 载波类型可以包括新载波类型和后向兼容载波类型 两种类型,也可也包括非独立新载波类型和独立新载波类型两种类型。其中, 新载波类型和后向兼容载波类型的某些预设特征不一致, 例如支持的传输模 式可以不同。 本发明所有实施例中, 载波的载波类型为新载波类型, 可以指 该载波支持第一传输模式, 该第一传输模式为除传输模式 1 到传输模式 10 之外的一种传输模式, 后向兼容载波不支持该第一传输模式。 本发明所有实 施例中, 载波的载波类型为后向兼容载波类型, 可以指该载波至少支持传输 模式 1到传输模式 10。
在本发明实施例中, 小区类型指承载该同步信号的载波对应的小区的小 区类型,承载该同步信号的载波对应的小区可以指部署承载该同步信号的载 波的小区, 或^载该同步信号的载波对应的小区可以指该载波所属的小区, 此处的小区可以是物理小区, 此处的小区类型可以包括宏小区 (Macro cell), 小小区 (Small cell)、 部属后向兼容载波的小区和微小区 (Pico cell)等。 在本发 明实施例中, 不同的小区类型可以对应于不同的序列, 也就是说, 通过同步 信号使用的序列, 就可以直接确定小区的具体类型, 例如, 宏小区或者小小 区。 此时本发明实施例中步骤 S120, 根据该同步信号使用的序列确定承载 该同步信号的载波的载波属性, 可以为根据该同步信号使用的序列确定承载 该同步信号的载波的小区类型。
在本发明实施例中, 在 S120中, 上述确定承载该同步信号的载波的载 波属性, 可以包括:
确定该同步信号使用的序列所属的序列集合;
根据序列集合与载波属性的对应关系, 以及该同步信号使用的序列所属 的序列集合, 确定承载该同步信号的载波的载波属性, 其中, 不同的序列集 合包括不同的序列。
具体地说, 用户设备在确定同步信号使用的序列之后, 可以确定该序列 所属的序列集合, 并根据序列集合与载波属性的对应关系、 以及该序列所属 的序列集合而确定承载该同步信号的载波的载波属性, 例如, 确定承载该同 步信号的载波的类型、 双工方式、 系统带宽、 小区类型、 类型和双工方式、 双工方式和系统带宽、 类型和系统带宽、 或者载波的类型和双工方式和系统 带宽等。 其中, 不同的序列集合可以包括不同的序列。
应理解, 本发明实施例所述的序列集合可以包括多个序列, 也可以只包 括一个序列。
还应理解, 在本发明实施例中, 序列集合与载波属性的对应关系可以为 主同步序列集合与载波属性的对应关系,也可以是辅同步序列集合与载波属 性的对应关系; 当然, 也可以是(主同步序列 +辅同步序列) 集合与载波属 性的对应关系, 此时, 则需要主同步信号序列与辅同步信号序列共同确定载 波属性。
在本发明实施例中, 上述载波属性可以为载波类型, 序列集合与载波属 性的对应关系可以为序列集合与载波类型的对应关系, 该序列集合与载波类 型的对应关系可以包括: 第一序列集合对应后向兼容载波类型和第二序列集 合对应新载波类型; 上述根据序列集合与载波属性的对应关系, 以及该同步 信号使用的序列所属的序列集合, 确定承载该同步信号的载波的载波属性, 可以包括:
若该同步信号使用的序列所属的序列集合为第一序列集合, 则承载该同 步信号的载波的载波类型为后向兼容载波类型, 若该同步信号使用的序列所 属的序列集合为第二序列集合, 则承载该同步信号的载波的载波类型为新载 波类型。
在本发明实施例中, 上述同步信号可以为主同步信号, 第一序列集合包 括的序列和第二序列集合包括的序列可以都为 ZC ( Zadoff-Chu )序列。其中,
ZC序列可以根据根序列索引 u 通过公式 _ w = 0,l,...,30
Figure imgf000013_0001
[i}63 w = 31,32,一,61 定, 即序列集合中所包括的序列 可以根据该序列的根索引确定。
其中, 上述第一序列集合可以包括三个 ZC序列, 该三个 ZC序列的根 序列索引可以分别为 25、 29和 34; 该第二序列集合可以包括三个 ZC序歹 ij , 该三个 ZC序列中的一个序列的根序列索引可以为 38,其他两个序列的根序 列索引之和为 63, 例如, 其他两个序列的根序列索引也可以为 20和 43。
其中, 上述根序列索引的值只是一种实现方式, 本发明实施例中的根序 列索引也可以有其他的取值, 本发明实施例并不对此进行限定。
其中, 上述第一序列集合包括的三个 ZC序列可以分别对应物理层小区 标识组内的三个物理层小区标识, 且所述第二序列集合包括的三个 ZC序列 可以分别对应物理层小区标识组内的三个物理层小区标识。用户设备可以根 据该同步信号使用的序列确定承载该同步信号的载波的物理层小区标识。 即 用户设备根据该同步信号使用的序列确定承载该同步信号的载波的载波类 型的同时, 还可以根据该同步信号使用的序列确定该载波的物理小区标识。
由于不同的载波类型对应于不同的主同步信号序列,用户设备可以根据 该主同步信号使用的序列确定载波类型, 当用户设备获知了载波类型后, 就 能获知辅同步信号的位置,从而无需对不同载波类型的辅同步信号的位置进 行盲检(仅需根据不同循环前缀(cyclic prefix, 筒称 CP )长度进行辅同步 信号的盲检), 从而节省用户设备的电量, 并且减少盲检假设从而提高检测 性能。另外,由于新载波类型和后向兼容载波类型使用的主同步序列不一致, 使得仅支持后向兼容载波的用户设备无法检测到新载波类型上发送的主同 步信号, 从而不会尝试接入该新载波类型, 节省了用户设备的电量, 使得用 户设备能及时得到服务。 若载波类型为非独立新载波类型, 则用户设备就不 会尝试驻留在该载波上, 从而节省了用户设备的电量。
在本发明实施例中, 上述同步信号可以为辅同步信号, 第一序列集合所 包括的序列和第二序列集合所包括的序列可以都为由两个 31 的二进制序列 构成的序列。 该第一序列集合和该第二序列集合均可包括 168 x 2个序列, 其中, 用户设备可以通过以下几种方式确定每个序列集合所包括的序列。 方式 1

从而, 由于不同的载波类型对应于不同的辅同步信号序列, 用户设备可 以根据该辅同步信号使用的序列确定载波类型, 当用户设备获知了载波类型 后, 若为非独立新载波类型, 则用户设备就不会尝试驻留在该载波上, 从而 节省了用户设备的耗电。 另外, 由于新载波类型和后向兼容载波类型使用的 辅同步序列不一致,使得仅支持后向兼容载波的用户设备无法检测到新载波 类型上发送的辅同步信号, 从而不会尝试接入该新载波类型, 减少了用户设 备的耗电, 使得用户设备能及时得到服务。
在本发明实施例中, 该序列集合与载波属性的对应关系可以为序列集合 与双工方式的对应关系, 该序列集合与载波类型的对应关系可以包括: 第三 序列集合对应频分双工, 第四序列集合对应时分双工; 则该根据该同步信号 使用的序列确定承载该同步信号的载波的载波属性, 可以包括:
若该同步信号使用的序列属于第三序列集合, 则承载该同步信号的载波 的双工方式为频分双工, 若该同步信号使用的序列属于第四序列集合, 则承 载该同步信号的载波的双工方式为时分双工。
因此, 由于不同的双工方式对应于不同的同步信号序列, 从而使得用户 设备能够根据检测的同步信号确定载波的双工方式,从而避免用户设备接入 载波时需盲检多套 PSS/SSS的位置, 从而筒化了用户设备的实现复杂度, 减 少用户设备的耗电。
以上已通过序列集合与载波属性的对应关系为序列集合与载波类型的 对应关系, 或为序列集合与双工方式的对应关系为例进行了说明, 本发明实 施例中的序列集合与载波属性的对应关系还可以为序列集合与系统带宽的 对应关系。
从而, 由于不同的系统带宽对应于不同的序列, 用户设备可以直接通过 同步信号使用的序列确定系统带宽, 从而能根据该系统带宽检测广播信息。
在本发明实施例中,序列集合与载波属性的对应关系可以为序列集合与 小区类型的对应关系, 该序列集合与小区类型的对应关系可以包括: 第五序 列集合对应宏小区, 第六序列集合对应小小区; 则根据序列集合与载波属性 的对应关系, 以及该同步信号使用的序列所属的序列集合, 确定承载该同步 信号的载波的载波属性, 可以包括:
若该同步信号使用的序列所属的序列集合为第五序列集合, 则承载该同 步信号的载波的小区类型为宏小区,若该同步信号使用的序列所属的序列集 合为第六序列集合, 则承载该同步信号的载波的小区类型为小小区。
从而, 由于不同的小区类型对应于不同的序列, 用于设备可以通过同步 信号使用的序列确定小区类型,从而能够根据小区类型对应的数据传输机制 进行数据的收发。
应理解, 本发明实施例中的序列集合与载波属性的对应关系还可以为序 列集合与载波类型、 双工方式、 小区类型和系统带宽中的至少两种的对应关 系, 从而, 用户设备在确定了同步信号使用的序列之后, 可以根据该同步信 号使用的序列, 确定承载该同步信号的载波属性、 系统带宽、 小区类型和双 工方式中的至少两种。
例如,在序列集合与载波属性的对应关系中,新载波类型和频分双工下, 对应的序列集合为 (A, B, C ); 新载波类型和时分双工下, 对应的序列集 合为 (D, E, F ); 后向兼容载波和频分双工下, 对应的载波类型为(G, H, I ); 后向兼容载波和时分双工下, 对应的序列集合为 (K, M, N ); 则如果 用户设备检测到的同步信号使用的序列为 D, 则可以确定承载该同步信号的 载波的类型为新载波类型, 对应的双工方式为时分双工。 其中, 若序列集合 中的每一个序列对应于物理层小区标识,则可以将 D对应的物理层小区标识 确定为承载该同步信号的载波的物理层小区标识。
因此, 在本发明实施例中, 通过检测同步信号, 确定该同步信号使用的 序列, 根据该同步信号使用的序列确定承载该同步信号的载波的载波属性, 从而筒化了用户设备的实现复杂度。

从而, 由于不同的载波类型对应于不同的主同步信号序列, 基站可以根 据确定的载波类型确定主同步信号使用的序列,将该主同步信号使用的序列 映射到该载波上发送给用户设备, 用户设备可以根据该主同步信号使用的序 列确定载波类型, 当用户设备获知了载波类型后, 就能获知辅同步信号的位 置, 从而无需对不同载波类型的辅同步信号的位置进行盲检(仅需根据不同 CP长度进行辅同步信号的盲检), 从而节省用户的耗电, 并且减少盲检假设 从而提高检测性能。 另外, 由于新载波类型和后向兼容载波类型使用的主同 步序列不一致,使得仅支持后向兼容载波的用户设备无法检测到新载波类型 上发送的主同步信号, 从而不会尝试接入该新载波类型, 减少了用户设备的 耗电, 使得用户设备能及时得到服务。 若载波类型为非独立新载波类型, 则 用户设备就不会尝试驻留在该载波上, 从而节省了用户设备的电量。

(n) = z((n + im^ mod 8)) mod 31)
此时 , mQ 和 如表 1 所示 , 且 ·) = 1_2 (0 , 0<
(7+5) = ( (7+4)+ (7 +2)+ (7 +l)+ (7)) mod 2, 0<Τ<25 x(0) = 0, χ(ί) = 0, x(2) = 0, x(3) = 0, (4) = l。
方式二
第二序列集合中的序列按照公式 2 生成, 但此时 和 ^ t)对应 χ(ι +5) = (χ(ι +4) + x(J + 2) + x(T +l) +x(i )) mod 2, 0<7<25 , (η)和 z^ in)对应 χ(Γ + 5) = (χ(Γ + 2) + x(T)) mod 2, 0 < ί < 25 , 其他同方式 1。
方式三

从而, 由于不同的载波类型对应于不同的辅同步信号序列, 基站可以根 据确定的载波类型确定辅同步信号使用的序列,将该辅同步信号使用的序列 映射到该载波上发送给用户设备, 用户设备可以根据该辅同步信号使用的序 列确定载波类型, 当用户设备获知了载波类型后, 若为非独立新载波类型, 则用户设备就不会尝试驻留在该载波上,从而节省了用户设备的耗电。另夕卜, 由于新载波类型和后向兼容载波类型使用的辅同步序列不一致,使得仅支持 后向兼容载波的用户设备无法检测到新载波类型上发送的辅同步信号,从而 不会尝试接入该新载波类型, 减少了用户设备的耗电, 使得用户设备能及时 得到服务。
在本发明实施例中, 该载波属性可以为双工方式, 该序列集合与载波属 性的对应关系可以为序列集合与双工方式的对应关系, 第三序列集合对应频 分双工, 第四序列集合对应时分双工; 则该确定该同步信号使用的序列, 可 以包括:
若承载同步信号的载波的双工方式为频分双工, 则该同步信号使用的序 列属于该第三序列集合, 若承载同步信号的载波的双工方式为时分双工, 则 该同步信号使用的序列属于该第四序列集合。
因此, 由于不同的双工方式对应于不同的同步信号序列, 基站可以根据 确定的双工方式确定同步信号使用的序列,将该同步信号使用的序列映射到 该载波上发送给用户设备,从而使得用户设备能够根据检测的同步信号确定 载波的双工方式, 从而避免用户设备接入载波时需盲检多套 PSS/SSS 的位 置, 并避免用户设备需通过盲检 CRS 来进一步识别载波双工方式, 从而筒 化了用户设备的实现复杂度, 减少用户设备的耗电。
以上以序列集合与载波属性的对应关系为序列集合与载波类型的对应 关系, 或为序列集合与双工方式的对应关系为例进行了说明, 本发明实施例 中的序列集合与载波属性的对应关系还可以为序列集合与系统带宽的对应 关系。
从而, 由于不同的系统带宽对应于不同的序列, 基站可以根据确定的系 统带宽确定同步信号使用的序列,将该同步信号使用的序列映射到该载波上 发送给用户设备, 用户设备可以直接通过同步信号使用的序列确定系统带 宽, 从而能根据该系统带宽检测广播信息。
在本发明实施例中,序列集合与载波属性的对应关系可以为序列集合与 小区类型的对应关系, 该序列集合与小区类型的对应关系可以包括: 第五序 列集合对应宏小区, 第六序列集合对应小小区; 则该确定该同步信号使用的 序列所属的序列集合, 可以包括:
若该承载该同步信号的载波的小区类型为宏小区, 则该同步信号使用的 序列属于该第五序列集合, 若该承载该同步信号的载波的小区类型为小小 区, 则该同步信号使用的序列属于该第六序列集合。
从而, 由于不同的小区类型对应于不同的序列, 基站可以根据确定的小 区类型确定同步信号使用的序列,将该同步信号使用的序列映射到该载波上 发送给用户设备, 用户设备可以通过同步信号使用的序列确定小区类型, 从 而能够根据小区类型对应的数据传输机制进行数据的收发。
应理解, 本发明实施例中的序列集合与载波属性的对应关系还可以为序 列集合与载波类型、 双工方式、 小区类型和系统带宽中的至少两种的对应关 系, 从而, 基站在确定承载该同步信号的载波类型、 系统带宽、 小区类型和 双工方式中的至少两种之后, 可以 ^据已确定的载波属性, 确定该同步信号 使用的序列。
例如,在序列集合与载波属性的对应关系中,新载波类型和频分双工下, 对应的序列集合为(A );新载波类型和时分双工下,对应的序列集合为(D ); 后向兼容载波和频分双工下, 对应的序列集合为(G ); 后向兼容载波和时分 双工下, 对应的序列集合为(K ); 在基站确定承载该同步信号的载波为新载 波类型, 对应的双工方式为时分双工时, 则选择使用的序列可以为 D。
因此, 在本发明实施例中, 通过基于承载同步信号的载波的载波属性确 定该同步信号使用的序列,将该同步信号使用的序列映射到该载波上发送给 用户设备, 可以避免用户设备接入载波时需盲检多套 PSS/SSS的位置, 并避 免用户设备需通过盲检 CRS 来进一步确定载波属性, 从而筒化了用户设备 的实现复杂度, 减少用户设备的耗电。
