Description

一种传输广播消息的方法和装置 技术领域
本发明涉及通信领域， 特别涉及一种传输广播消息的方法和装置。 背景技术
LTE(Long Term Evolution, 长期演进)是 3G ( 3rd-generation , 第三代移动 技术通信） 的演进， 它改进并增强了 3G的空中接入技术， 改善了小区边缘用 户的性能， 在 LTE8、 9、 10 或 11 系统中， 基站可以通过 PBCH ( Physical Broadcasting Channel,物理广播信道 )来传输广播消息给 UE ( User Equipment, 用户设备）。
其中， 在 LTE8、 9、 10或 11系统中， 所有载波均为后向兼容载波， 后向 兼容载波上 PBCH通过 CRS ( Cell-specific Reference Signal, 小区特定参考信 号）来进行解调，而在 LTE版本 12以后的版本中引入了 NCT( New Carrier Type, 新载波类型）， NCT仅在部分子帧和或部分频带发送单天线口 CRS, 且该单天 线口 CRS不用作解调， 因此不能继续使用后向兼容载波上 PBCH来传输广播 消息， 需重新设计 NCT上广播消息的传输机制。 另一方面， 即使 NCT中的单 天线口 CRS用于 PBCH的解调， 由于该 CRS的密度较低， 在使用 PBCH来传 输广播消息时， 也会降低广播消息传输性能。 发明内容

如图 3所示，本发明实施例提供了一种传输广播消息的方法，该方法包括： 步骤 301: 基站确定广播信道的传输资源；
其中， 广播信道的传输资源可以包含广播信道的参考信号、 承载广播信道 的子帧、 承载广播信道的符号、 承载广播信道的物理资源块集合和承载广播信 道的资源单元中的一种或多种。
其中， 基站确定广播信道的传输资源包含的广播信道的参考信号， 可以包 括： 基站确定广播信道的参考信号为 DMRS。
其中， 基站确定广播信道的传输资源包含的承载广播信道的子帧， 可以包 括：基站确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧，或者 确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下一个子帧。
其中，当基站确定承载广播信道的子帧为承载同步信号和 /或发现信号的子 帧时，基站可以在承载同步信号和 /或发现信号的子帧的中心的 6个物理资源块 上的 4个连续的符号上承载物理广播信道。
其中，当基站确定承载广播信道的子帧为承载同步信号和 /或发现信号的子 帧的下一个子帧时，基站可以在承载广播信道的子帧为承载同步信号和 /或发现 信号的子帧的下一个子帧中心的 6个物理资源块上的 4个连续的符号上承载物 理广播信道。
其中，确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下 一个子帧，可以指确定承载广播信道的子帧为所有承载同步信号和 /或发现信号 的子帧的下一子帧， 也可以指确定承载广播信道的子帧为部分承载同步信号和 /或发现信号的子帧的下一子帧。
其中，确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下 一个子帧，也可以指确定承载广播信道的子帧为承载同步信号和 /或发现信号的 子帧的下一子帧中的部分子帧，当承载广播信道的子帧为承载同步信号和 /或发 现信号的子帧的下一子帧中的部分子帧时，承载同步信号和 /或发现信号的子帧 的子帧编号为偶数。
其中， 基站确定广播信道的传输资源包含的广播信道的符号， 可以包括以 下两种方式：
方式一： 基站确定承载广播信道的符号为与承载 DMRS 的符号相邻的符 号中的部分符号或全部符号。
其中， 承载广播信道的符号与承载 DMRS 的符号相邻， 承载广播信道的 符号可以为承载 DMRS的符号的下一个符号。 如图 4所示， 以承载广播信号 的符号在一个子帧内有四个符号为例， 承载 DMRS 的符号为第一时隙中的符 号 2和符号 3, 以及第二时隙中的符号 2和符号 3, 承载广播信道的符号为第 一时隙中的符号 1和符号 4, 以及第二时隙中的符号 1和符号 4, 可以看出， 承载广播信道的符号与承载 DMRS的符号相邻。
其中， 承载广播信道的符号可以为与承载 DMRS 的符号相邻的符号中的 部分符号， 承载广播信道的符号也可以为与承载 DMRS 的符号相邻的符号中 的全部符号。
其中， 当基站确定承载广播信道的符号为与承载 DMRS 的符号相邻的符 号中的部分信号或者全部符号时， 承载广播信道的符号与承载 DMRS 的符号 相邻， 由于 UE基于 DMRS进行广播信道的信道估计， 而承载广播信道的符号 与承载 DMRS的符号相邻， 使得基站进行信道估计得到更准确的信道估计值， 进而 UE基于该估计值能够更准确进行广播信道译码， 从而能够提高广播信道 的传输性能。
方式二： 基站根据承载广播信道的载波的小区标识确定承载广播信道的符 号。
其中， 在该方式二下， 基站根据承载广播信道的载波的小区标识确定承载 广播信道的符号， 可以为： 基站根据承载广播信道的载波对应的物理小区的物 理小区标识确定承载广播信道的符号。
其中， 载波对应的物理小区可以为部署该载波的小区。
其中， 载波的物理小区标识可以为高层配置的。
其中， 基站根据承载广播信道的载波的小区标识确定承载广播信道的符 号， 还可以为： 基站根据承载广播信道的载波的虚拟小区标识确定承载广播信 道的符号。
其中， 其中虚拟小区标识是高层配置的， 不同物理小区可对应相同的虚拟 小区标识。
其中， 需要说明的是， 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同一个物理小 区。
该方式二可以使得部署相同载波的不同小区在不同的符号上传输广播信 道， 从而减少小区间干扰， 提高广播消息的传输性能。
需要说明的是， 方式一和方式二是基站确定广播信道的传输资源包含的广 播信道的符号的两种实现方式， 即本发明实施例提供的两种可能的方法， 实际 系统中， 可以单独采用方式一或方式二来实现， 也可以采用方式一和方式二相 结合的方式实现， 但基站侧和 UE侧需要按照统一的规则来进行确定承载广播 信道的符号。
其中，基站确定广播信道的传输资源包含的承载广播信道的物理资源块集 合， 可以包括： 基站确定承载广播信道的物理资源块集合为承载同步信号和 / 或发现信号的物理资源块集合， 或者，
基站确定承载广播信道的物理资源块集合为频域起始位置与承载同步信 号和 /或发现信号的物理资源块集合的频域起始位置存在预定偏移的物理资源 块集合。
其中， 频域起始位置指物理资源块集合中物理资源块编号最小的物理资源 块的物理资源块编号。
如图 5所示，承载广播信道的物理资源块集合和承载同步信号和 /或发现信 号的物理资源块集合均为第一物理资源块集合。
如图 6所示， 承载广播信道的物理资源块集合为第二物理资源块集合， 承 载同步信号和 /或发现信号的物理资源块集合为第一物理资源块集合,且第二物 理资源块集合的频域起始位置与第一物理资源块集合的频域起始位置存在 6个 物理资源块的预定偏移。
其中，当基站确定承载广播信道的物理资源块集合为承载同步信号和 /或发 现信号的物理资源块集合， 或者， 承载广播信道的物理资源块集合为频域起始 位置与承载同步信号和 /或发现信号的物理资源块集合的频域起始位置存在预 定偏移的物理资源块集合时，承载广播信道的物理资源块集合与承载同步信号 和 /或发现信号的物理资源块集合具有固定的位置关系， UE在检测到同步信号 和 /或发现信号后，就可以根据承载广播信道的物理资源块集合与承载同步信号 和 /或发现信号的物理资源块集合的固定的位置关系确定承载广播信道的物理 资源块集合， 从而可以避免 UE在多个可能的位置上盲检承载广播信道的物理 资源块集合， 节省了 UE的功率消耗， 并能够快速获取广播信道上承载的广播 消息， 减少了 UE完成时频同步的时间。
其中， 基站确定广播信道的传输资源包含的承载广播信道的资源单元， 可 以包括： 根据预设的假设条件确定承载广播信道的资源单元， 假设条件用于假 设存在单天线口的 CRS发送。
其中， 在基站已经确定出承载广播信道的子帧， 以及该承载广播信道的子 帧上的符号后， 基站假设存在单天线口的 CRS发送， 则扣除该承载广播信道 的子帧的符号中用于承载单天线口的 CRS 的资源单元， 扣除该承载广播信道 的子帧的符号中用于承载单天线口的 CRS 的资源单元后， 剩下的资源单元中 的全部资源单元或者部分资源单元为承载广播信道的资源单元。
需要说明的是， 该步骤中广播信道的传输资源可以包含广播信道的参考信 号、 承载广播信道的子帧、 承载广播信道的符号、 承载广播信道的物理资源块 集合和承载广播信道的资源单元中的一种或多种， 即该步骤可以包括基站确定 广播信道的传输资源包含的广播信道的参考信号、基站确定广播信道的传输资 源包含的承载广播信道的子帧、基站确定广播信道的传输资源包含的广播信道 的符号、基站确定广播信道的传输资源包含的承载广播信道的物理资源块集合 和基站确定广播信道的传输资源包含的承载广播信道的资源单元中的一种或 多种， 举例来说， 该步骤可以包括所有以上动作， 此时基站先确定承载广播信 道的子帧， 然后确定该承载广播信道的子帧中用于承载广播信道的符号， 然后 确定该用于承载广播信道的符号上用于承载广播信道的资源单元， 并确定广播 信道的参考信号以使得步骤 302中基站能采用该基于该广播信道的参考信号的 传输方案在承载广播信道的资源单元上将广播消息发送给用户设备。
步骤 302: 基站基于广播信道的传输资源， 发送广播消息给 UE;
该步骤中， 基站基于步骤 301确定的广播信道的传输资源， 发送广播消息 给 UE。
例如，基站可以采用基于步骤 301确定的广播信道的参考信号的传输方案 发送广播消息给 UE。其中，当广播信道的参考信号为 DMRS时，该基于 DMRS 的传输方案可以为基于 DMRS的随机波束成行 (Random beamforming)或为基于 DMRS 的发射分集。 例如， 当步骤 301 中基站确定广播信道的参考信号为 DMRS, 且该 DMRS在天线口 7和天线口 9上传输时， 该步骤 302基站可采用 基于天线口 7和天线口 9的随机波束成行传输方案发送广播消息给 UE, 具体 可以为基站交替使用天线口 7和天线口 9传输承载广播信道的符号上用于传输 广播信道的资源单元上承载的信号。 由于天线口 7 和天线口 9是采用 FDM ( Frequency-division multiplexing, 频分多路复用）的方式， 因而能使得该广播 信道对应的 DMRS 的频域密度较高， 从而提高该物理广播信道的传输性能。 采用类似使传输 DMRS 的天线口中至少有两个天线口是频分复用的思想， 该 步骤也可以采用基于天线口 8和天线口 9的随机波束成行传输方案发送广播消 息给 UE、或采用基于天线口 8和天线口 10的随机波束成行传输方案发送广播 消息给 UE、或基于天线口 7和天线口 10的随机波束成行传输方案发送广播消 息给 UE。 当广播信道的参考信号为 4天线 DMRS时， 该步骤可以为基于天线 口 7、 天线口 9、 天线口 11和天线口 13发送广播消息给用户设备， 也可以为 基于天线口 8、 天线口 10、 天线口 12和天线口 14发送广播消息给用户设备。 以基于天线口 7、 天线口 9、 天线口 11和天线口 13发送广播消息给用户设备 为例， 此时该步骤可以依次循环使用天线口 7、 天线口 9、 天线口 11和天线口 13传输承载广播信道的符号上用于传输广播信道的资源单元上承载的信号。
该步骤中， 当基站基于步骤 301确定的广播信道的参考信号的传输方案发 送广播消息给 UE时， 不同小区可以基于不同的 DMRS天线口进行传输。
例如， 小区 1和小区 2为相邻的两个小区， 小区 1采用天线口 7和天线口 9传输广播信道， 小区 2采用天线口 8和天线口 10传输广播信道。 由于不同天 线口之间相互正交，可以减小小区间干扰，对密集小区布网的场景尤其有好处。
其中， 当不同小区采用不同的天线口时，基站可以在同步信号和 /或发现信 号上承载指示本小区使用的天线口的信息， 以使得 UE在检测到同步信号和 / 或发现信号后，根据同步信号和 /或发现信号上承载的指示本小区使用的天线口 的信息， 获取传输广播信道的天线口， 从而避免 UE做盲检， 节省 UE检测广 播信道的时间， 提高广播信道的传输性能。 另外， 基站也可以将广播信道的参 考信号的 DMRS 天线口信息加扰在广播信道的循环冗余校验 CRC ( Cyclic Redundancy Check, 循环冗余码校验）上。
该步骤中， 基站还可以先采用雷德密勒 RM码对广播消息进行信道编码， 然后将编码后的广播消息映射到承载物理广播信道的资源单元上并发送给 UE。 需要说明的是，本发明实施例中的广播消息可以包含下行系统带宽和 /或系 统帧号和 /或载波属性和 /或增强的公共搜索空间位置。 其中， 载波属性可用于 指示该载波为新载波类型， 增强的公共搜索空间的位置可以指增强的公共搜索 空间的频域位置， 即所占用的物理资源块。
步骤 303: UE确定广播信道的传输资源；
其中， 广播信道的传输资源包含广播信道的参考信号、 承载广播信道的子 帧、 承载广播信道的符号、 承载广播信道的物理资源块集合和承载广播信道的 资源单元中的一种或多种。
其中， UE确定广播信道的传输资源包含的广播信道的参考信号， 可以包 括： UE确定广播信道的参考信号为 DMRS。
其中， UE确定广播信道的传输资源包含的承载广播信道的子帧， 可以包 括：， UE确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧， 或 者确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下一个子 帧。
其中， 当 UE确定承载广播信道的子帧为承载同步信号和 /或发现信号的子 帧时，可以进一步确定该广播信道 载在同步信号和 /或发现信号的子帧的中心 的 6个物理资源块上的 4个连续的符号上。
其中， 当 UE确定承载广播信道的子帧为承载同步信号和 /或发现信号的子 帧的下一个子帧时， 可以进一步确定该广播信道承载在承载广播信道的子帧为 承载同步信号和 /或发现信号的子帧的下一个子帧中心的 6个物理资源块上的 4 个连续的符号上。
其中，确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下 一个子帧，可以指确定承载广播信道的子帧为所有承载同步信号和 /或发现信号 的子帧的下一子帧， 也可以指确定承载广播信道的子帧为部分承载同步信号和 /或发现信号的子帧的下一子帧。
其中，确定承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下 一个子帧，也可以指确定承载广播信道的子帧为承载同步信号和 /或发现信号的 子帧的下一子帧中的部分子帧，当承载广播信道的子帧为承载同步信号和 /或发 现信号的子帧的下一子帧中的部分子帧时，承载同步信号和 /或发现信号的子帧 的子帧编号为偶数。 其中， UE确定广播信道的传输资源包含的广播信道的符号， 可以包括以 下两种方式：
方式一： UE确定承载广播信道的符号为与承载 DMRS的符号相邻的符号 中的部分符号或全部符号。
其中， 承载广播信道的符号与承载 DMRS 的符号相邻， 承载广播信道的 符号可以为承载 DMRS的符号的下一个符号。 如图 4所示， 以承载广播信号 的符号在一个子帧内有四个符号为例， 承载 DMRS 的符号为第一时隙中的符 号 2和符号 3, 以及第二时隙中的符号 2和符号 3, 承载广播信道的符号为第 一时隙中的符号 1和符号 4, 以及第二时隙中的符号 1和符号 4, 可以看出， 承载广播信道的符号与承载 DMRS的符号相邻。
其中， 承载广播信道的符号可以为与承载 DMRS 的符号相邻的符号中的 部分符号， 承载广播信道的符号也可以为与承载 DMRS 的符号相邻的符号中 的全部符号。
其中，当 UE确定承载广播信道的符号为与承载 DMRS的符号相邻的符号 中的部分信号或者全部符号时， 承载广播信道的符号与承载 DMRS 的符号相 邻， 由于 UE基于 DMRS进行广播信道的信道估计， 而承载广播信道的符号与 承载 DMRS 的符号相邻， 使得基站进行信道估计得到更准确的信道估计值， 进而 UE基于该估计值能够更准确进行广播信道译码， 从而能够提高广播信道 的传输性能。
方式二： UE根据承载广播信道的载波的小区标识确定承载广播信道的符 号。
其中， UE根据承载广播信道的载波的小区标识确定承载广播信道的符号 的方法和步骤 301中基站根据承载广播信道的载波的小区标识确定承载广播信 道的符号的方法相同， 此处不再赘述。
其中， UE确定广播信道的传输资源包含的承载广播信道的物理资源块集 合， 可以包括： UE确定承载广播信道的物理资源块集合为承载同步信号和 /或 发现信号的物理资源块集合， 或者，
UE确定承载广播信道的物理资源块集合为频域起始位置与承载同步信号 和 /或发现信号的物理资源块集合的频域起始位置存在预定偏移的物理资源块 集合。 其中， 频域起始位置指物理资源块集合中物理资源块编号最小的物理资源 块的物理资源块编号。
如图 5所示，承载广播信道的物理资源块集合和承载同步信号和 /或发现信 号的物理资源块集合均为第一物理资源块集合。
如图 6所示， 承载广播信道的物理资源块集合为第二物理资源块集合， 承 载同步信号和 /或发现信号的物理资源块集合为第一物理资源块集合,且第二物 理资源块集合的频域起始位置与第一物理资源块集合的频域起始位置存在 6个 物理资源块的预定偏移。
其中， 当 UE确定承载广播信道的物理资源块集合为承载同步信号和 /或发 现信号的物理资源块集合， 或者， 承载广播信道的物理资源块集合为频域起始 位置与承载同步信号和 /或发现信号的物理资源块集合的频域起始位置存在预 定偏移的物理资源块集合时， 由于承载广播信道的物理资源块集合与承载同步 信号和 /或发现信号的物理资源块集合具有固定的位置关系， UE在检测到同步 信号和 /或发现信号后，就可以根据承载广播信道的物理资源块集合与承载同步 信号和 /或发现信号的物理资源块集合的固定的位置关系确定承载广播信道的 物理资源块集合， 从而可以避免 UE在多个可能的位置上盲检承载广播信道的 物理资源块集合， 节省了 UE的功率消耗， 并能够快速获取广播信道上承载的 广播消息， 减少了 UE完成时频同步的时间。
其中， UE确定广播信道的传输资源包含的承载广播信道的资源单元， 可 以包括： 根据预设的假设条件确定承载广播信道的资源单元， 假设条件用于假 设存在单天线口的 CRS发送。
其中， 在 UE已经确定出承载广播信道的子帧， 以及该承载广播信道的子 帧上的符号后， UE假设存在单天线口的 CRS发送， 则扣除该承载广播信道的 子帧的符号中用于承载单天线口的 CRS 的资源单元， 扣除该承载广播信道的 子帧的符号中用于承载单天线口的 CRS 的资源单元后， 剩下的资源单元中的 全部资源单元或者部分资源单元为承载广播信道的资源单元。
需要说明的是， 该步骤中广播信道的传输资源可以包含广播信道的参考信 号、 承载广播信道的子帧、 承载广播信道的符号、 承载广播信道的物理资源块 集合和承载广播信道的资源单元中的一种或多种， 即该步骤可以包括 UE确定 广播信道的传输资源包含的广播信道的参考信号、 UE确定广播信道的传输资 源包含的承载广播信道的子帧、 UE确定广播信道的传输资源包含的广播信道 的符号、 UE确定广播信道的传输资源包含的承载广播信道的物理资源块集合 和 UE确定广播信道的传输资源包含的承载广播信道的资源单元中的一种或多 种， 举例来说， 该步骤可以包括所有以上动作， 此时 UE先确定承载广播信道 的子帧， 然后确定该承载广播信道的子帧中用于承载广播信道的符号， 然后确 定该用于承载广播信道的符号上用于承载广播信道的资源单元， 并确定广播信 道的参考信号以使得步骤 304中 UE能采用该基于该广播信道的参考信号的传 输方案对广播信道进行译码。
步骤 304: UE基于广播信道的传输资源， 获取广播信道承载的广播消息。 该步骤中， UE基于步骤 303确定的广播信道的传输资源， 获取广播信道 承载的广播消息。
例如， UE可以采用基于步骤 303确定的广播信道的参考信号对广播信道 进行译码， 获取广播信道承载的广播消息。
其中， 当广播信道的参考信号为 DMRS时， 该基于 DMRS的传输方案可 以为基于 DMRS的随机波束成行 (Random beamforming)或为基于 DMRS的发 射分集。 例如， 当步骤 303 中 UE确定广播信道的参考信号为 DMRS, 且该 DMRS在天线口 7和天线口 9上传输时， 该步骤 304中， UE可采用基于天线 口 7和天线口 9的随机波束成行传输方案对广播信道进行译码， 获取广播信道 承载的广播消息， 具体可以为交替使用天线口 7和天线口 9对承载广播信道的 符号上用于传输广播信道的资源单元上承载的信号进行译码。 由于天线口 7和 天线口 9是采用 FDM的方式， 因而能使得该广播信道对应的 DMRS的频域密 度较高， 从而提高该物理广播信道的传输性能。 采用类似使传输 DMRS 的天 线口中至少有两个天线口是频分复用的思想， 该步骤也可以采用基于天线口 8 和天线口 9的随机波束成行传输方案对广播信道进行译码获取广播信道承载的 广播消息、 或采用基于天线口 8和天线口 10的随机波束成行传输方案对广播 信道进行译码获取广播信道承载的广播消息、 或基于天线口 7和天线口 10的 随机波束成行传输方案对广播信道进行译码获取广播信道承载的广播消息。 当 广播信道的参考信号为 4天线 DMRS时， 该步骤可以为基于天线口 7、 天线口 9、 天线口 11和天线口 13发对广播信道进行译码获取广播信道承载的广播消 息， 也可以为基于天线口 8、 天线口 10、 天线口 12和天线口 14对广播信道进 行译码获取广播信道承载的广播消息。 以基于天线口 7、 天线口 9、 天线口 11 和天线口 13发送广播消息给用户设备为例， 此时该步骤可以依次循环使用天 线口 7、 天线口 9、 天线口 11和天线口 13对承载广播信道的符号上用于传输 广播信道的资源单元上承载的信号进行译码。
该步骤中， 当 UE基于步骤 303确定的广播信道的参考信号的传输方案对广播 信道进行译码， 获取广播信道承载的广播消息时， 不同小区可以对应不同的 DMRS天线口。
例如， 小区 1和小区 2为相邻的两个小区， 小区 1采用天线口 7和天线口 9传输广播信道， 小区 2采用天线口 8和天线口 10传输广播信道。 由于不同天 线口之间相互正交，可以减小小区间干扰，对密集小区布网的场景尤其有好处。
其中， 当不同小区采用不同的天线口时，基站可以在同步信号和 /或发现信 号上承载指示本小区使用的天线口的信息， UE在检测到同步信号和 /或发现信 号后， 根据同步信号和 /或发现信号上承载的指示本小区使用的天线口的信息， 获取传输广播信道的天线口， 从而避免 UE做盲检， 节省 UE检测广播信道的 时间， 提高广播信道的传输性能。 另外， UE也可以通过广播信道的 CRC获取 广播信道的参考信号的 DMRS天线口信息。
该步骤中， UE还可以采用雷德密勒 RM码对广播信道承载的广播消息进 行译码， 获取广播信道承载的广播消息。
需要说明的是，本发明实施例中的广播消息可以包含下行系统带宽和 /或系 统帧号和 /或载波类型和 /或增强的公共搜索空间位置。 其中， 载波属性可用于 指示该载波为新载波类型， 增强的公共搜索空间的位置可以指增强的公共搜索 空间的频域位置， 即所占用的物理资源块。
其中， 在本发明实施例中， 广播信道可以为物理广播信道或增强的物理广 播信道。
需要说明的是， 本发明实施例中步骤 301和步骤 302为基站侧的步骤， 步 骤 303和步骤 304为 UE侧的步骤， 基站侧的步骤和 UE侧的步骤可以独立存 在， 也可以相互依赖存在。
通常， 基站侧按照广播信道的传输机制发送广播信道， UE侧按照相同的 广播信道的传输机制对广播信道进行接收， 由于基站和 UE采用的广播信道的 传输机制是相同的传输机制， 因而， 基站侧的步骤与 UE侧的步骤通常是对应 的。
例如， 当基站确定广播信道的参考信号为 DMRS 和承载广播信道的子帧 为承载同步信号和 /或发现信号的子帧时， 相应的， UE也确定广播信道的参考 信号为 DMRS和承载广播信道的子帧为承载同步信号和 /或发现信号的子帧； 当基站确定广播信道的参考信号为 DMRS、承载广播信道的子帧为承载同步信 号和 /或发现信号的子帧的下一个子帧， 以及承载广播信道的符号为与承载 DMRS 的符号相邻的符号时， 相应的， UE 也确定广播信道的参考信号为 DMRS,承载广播信道的子帧为承载同步信号和 /或发现信号的子帧的下一个子 帧， 以及承载广播信道的符号为与承载 DMRS 的符号相邻的符号； 当基站确 定承载广播信道的符号为与承载 DMRS 的符号相邻的符号中的全部符号时， UE确定承载广播信道的符号为与承载 DMRS 的符号相邻的符号中的全部符 号； 当基站根据承载广播信道的载波对应的物理小区的物理小区标识确定承载 广播信道的符号时， UE根据承载广播信道的载波对应的物理小区的物理小区 标识确定承载广播信道的符号； 当基站确定承载广播信道的物理资源块集合为 承载同步信号和 /或发现信号的物理资源块集合时， UE确定承载广播信道的物 理资源块集合为承载同步信号和 /或发现信号的物理资源块集合；当基站确定承 载广播信道的物理资源块集合为频域起始位置与承载同步信号和 /或发现信号 的物理资源块集合的频域起始位置存在预定偏移的物理资源块集合时， UE确 定承载广播信道的第二物理资源块集合为频域起始位置与承载同步信号和 /或 发现信号的第一物理资源块集合的频域起始位置存在预定偏移的物理资源块 集合； 当基站确定广播信道的参考信号为 DMRS, 且该 DMRS在天线口 7和 天线口 9上传输时， UE确定广播信道的参考信号为 DMRS, 且该 DMRS在天 线口 7和天线口 9上传输； 当基站采用雷德密勒 RM码对广播消息进行信道编 码时， UE采用雷德密勒 RM码对广播信道承载的广播消息进行译码， 获取广 播信道承载的广播消息。
在本发明实施例中， 基站确定广播信道的传输资源， 广播信道的传输资源 包含广播信道的参考信号、 承载广播信道的子帧、 承载广播信道的符号、 承载 广播信道的物理资源块集合和承载广播信道的资源单元中的一种或多种，基站 根据确定的广播信道的传输资源，发送广播消息给 UE, UE确定广播信道的传 输资源， 基于广播信道的传输资源， 获取广播信道承载的广播消息。 由于基站 以 DMRS 为参考信号， 解决了 NCT上如何传输广播消息的问题， 通过基于 DMRS的波束成形方案等提高广播消息的传输性能。 实施例 4

如图 6所示， 承载广播信道的物理资源块集合为第二物理资源块集合， 承 载同步信号和 /或发现信号的物理资源块集合为第一物理资源块集合,且第二物 理资源块集合的频域起始位置与第一物理资源块集合的频域起始位置存在 6个 物理资源块的预定偏移。
其中， 当 UE确定承载广播信道的物理资源块集合为承载同步信号和 /或发 现信号的物理资源块集合， 或者， 承载广播信道的物理资源块集合为频域起始 位置与承载同步信号和 /或发现信号的物理资源块集合的频域起始位置存在预 定偏移的物理资源块集合时，承载广播信道的物理资源块集合与承载同步信号 和 /或发现信号的物理资源块集合具有固定的位置关系， UE在检测到同步信号 和 /或发现信号后，就可以根据承载广播信道的物理资源块集合与承载同步信号 和 /或发现信号的物理资源块集合的固定的位置关系确定承载广播信道的物理 资源块集合， 从而可以避免 UE在多个可能的位置上盲检承载广播信道的物理 资源块集合， 节省了 UE的功率消耗， 并能够快速获取广播信道上承载的广播 消息， 减少了 UE完成时频同步的时间。
其中， 在 UE已经确定出承载广播信道的子帧， 以及该承载广播信道的子 帧上的符号后， UE可以基于四天线口的 CRS确定出承载广播信道的资源单元， UE首先确定承载广播信道的子帧的符号中用于承载四天线口的 CRS的资源单 元， 进而扣除该承载广播信道的子帧的符号中用于承载四天线口的 CRS 的资 源单元， 扣除该承载广播信道的子帧的符号中用于承载四天线口的 CRS 的资 源单元后， 剩下的资源单元中的全部资源单元或者部分资源单元为承载广播信 道的资源单元。
步骤 404: UE基于广播信道的传输资源， 获取广播信道承载的广播消息。 该步骤中， UE基于步骤 403确定的广播信道的传输资源， 获取广播信道 承载的广播消息。
例如， UE可以采用基于步骤 403确定的广播信道的参考信号对广播信道 进行译码， 获取广播信道承载的广播消息。 其中， 当广播信道的参考信号为第 一参考信号时， UE采用基于该第一参考信道的发射分集对广播信道进行译码， 获取广播消息。
该步骤中， UE还可以采用雷德密勒 RM码对广播信道承载的广播消息进 行译码， 获取广播信道承载的广播消息。
其中， 在本发明实施例中， 广播信道可以为物理广播信道或增强的物理广 播信道。
需要说明的是，本发明实施例中的广播消息可以包含下行系统带宽和 /或系 统帧号和 /或载波类型和 /或增强的公共搜索空间位置。 其中， 载波属性可用于 指示该载波为新载波类型， 增强的公共搜索空间的位置可以指增强的公共搜索 空间的频域位置， 即所占用的物理资源块。
需要说明的是， 本发明实施例中步骤 401和步骤 402为基站侧的步骤， 步 骤 403和步骤 404为 UE侧的步骤， 基站侧的步骤和 UE侧的步骤可以独立存 在， 也可以相互依赖存在。
通常， 基站侧按照广播信道的传输机制发送广播信道， UE侧按照相同的 广播信道的传输机制对广播信道进行接收， 由于基站和 UE采用的广播信道的 传输机制是相同的， 因而， 基站侧的步骤与 UE侧的步骤通常是对应的。
例如， 当基站确定广播信道的参考信号为第一参考信号和承载广播信道的 子帧为承载同步信号和 /或发现信号的子帧时， 相应的， UE也确定广播信道的 参考信号为第一参考信号和承载广播信道的子帧为承载同步信号和 /或发现信 号的子帧；当基站确定承载广播信道的物理资源块集合为承载同步信号和 /或发 现信号的物理资源块集合时， UE确定承载广播信道的物理资源块集合为承载 同步信号和 /或发现信号的物理资源块集合等。
在本发明实施例中， 基站确定广播信道的传输资源， 广播信道的传输资源 包含广播信道的参考信号、 承载广播信道的子帧、 承载广播信道的符号、 承载 广播信道的物理资源块集合和承载广播信道的资源单元中的一种或多种，基站 根据确定的广播信道的传输资源， 以第一参考信号为参考信号采用发射分集传 输方案发送广播消息给 UE, UE确定广播信道的传输资源，基于广播信道的传 输资源， 获取广播信道承载的广播消息， 解决了 NCT上如何传输广播消息的 问题， 通过基于第一参考信号的发射分集方案等提高广播消息的传输性能。 实施例 5
如图 9所示，本发明实施例提供了一种传输广播消息的方法，该方法包括： 步骤 501 : 基站确定广播信道的传输资源， 广播信道的传输资源包含广播 信道的参考信号、 承载广播信道的符号；
其中， 基站确定广播信道的传输资源包含的承载广播信道的符号， 包括： 确定承载广播信道的符号的个数为 1或 2。
其中，承载广播信道的符号可以为载波中心 6个物理资源块上的一个或者 两个符号。
其中， 广播消息可以为下行系统带宽。
其中， 广播消息也可为下行系统带宽和载波属性， 该载波属性用于指示该 载波为新载波类型。
其中， 不同小区承载广播信道的符号都位于载波中心 6个资源块上， 但不 同小区对应载波中心 6个资源块上的不同符号， 对于每个小区对应的符号， 基 站可以采用同步信道和 /或发现信号指示承载广播信道的符号的符号索引，由于 不同的小区在不同符号上传输广播消息， 可以减小小区间干扰， 对密集小区布 网的场景尤其有好处。
如图 10所示， 以承载广播信道的符号的个数为 1为例， 小区 A承载广播 信道的符号对应载波中心 6个物理资源块上第二时隙的符号 0, 小区 B承载广 播信道的符号对应载波中心 6个资源块上的第二时隙符号 1 , 小区 C承载广播 信道的符号对应载波中心 6个资源块上第二时隙的符号 2, 小区 D承载广播信 道的符号对应载波中心 6个资源块上第二时隙的符号 3 , 由于每个小区在不同 的符号上传输广播消息， 可以减小小区间干扰， 对密集小区布网的场景尤其有 好处。
其中，基站可以根据承载广播信道的载波的小区标识确定承载广播信道的 符号。基站根据承载广播信道的载波的小区标识确定承载广播信道的符号可以 为： 基站根据承载广播信道的载波对应的物理小区的物理小区标识确定承载广 播信道的符号。
其中， 载波对应的物理小区可以为部署该载波的小区。
其中， 载波的物理小区标识可以为高层配置的。 其中，基站根据承载广播信道的载波的小区标识确定承载广播信道的符号 还可以为： 基站根据承载广播信道的载波的虚拟小区标识确定承载广播信道的 符号。
其中， 虚拟小区标识是高层配置的， 不同物理小区可对应相同的虚拟小区 标识。
其中， 需要说明的是， 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。
其中， 基站确定广播信道的传输资源包含的广播信道的参考信号可以为 DMRS, 也可以为第一参考信号。
其中，基站确定广播信道的传输资源包含的广播信道的参考信号为 DMRS 的方法和实施例 3中基站确定广播信道的传输资源包含的广播信道的参考信号 为 DMRS的方法相同， 此处不再赘述。
其中，基站确定广播信道的传输资源包含的广播信道的参考信号为第一参 考信号的的方法和实施例 4中基站确定广播信道的传输资源包含的广播信道的 参考信号为第一参考信号的的方法的方法相同， 此处不再赘述。
步骤 502: 基站基于广播信道的传输资源， 发送广播消息给 UE;
该步骤中， 基站基于步骤 501确定的广播信道的传输资源， 发送广播消息 给 UE。
例如，基站可以采用基于步骤 501确定的广播信道的参考信号的传输方案 发送广播消息给 UE。 其中， 当基站确定广播信道的参考信号为 DMRS时， 该 基于 DMRS 的传输方案可以为基于 DMRS 的随机波束成行（Random beamforming)或为基于 DMRS的发射分集。 例如， 当步骤 501中基站确定广播 信道的参考信号为 DMRS, 且该 DMRS在天线口 7和天线口 9上传输时， 该 步骤 502中，基站可采用基于天线口 7和天线口 9的随机波束成行传输方案发 送广播消息给 UE, 具体可以为基站交替使用天线口 7和天线口 9传输承载广 播信道的符号上用于传输广播信道的资源单元上承载的信号。 由于天线口 7和 天线口 9是采用 FDM的方式， 因而能使得该广播信道对应的 DMRS的频域密 度较高， 从而提高该物理广播信道的传输性能。 采用类似使传输 DMRS 的天 线口中至少有两个天线口是频分复用的思想， 该步骤也可以采用基于天线口 8 和天线口 9的随机波束成行传输方案发送广播消息给 UE、 或采用基于天线口 8和天线口 10的随机波束成行传输方案发送广播消息给 UE、 或基于天线口 7 和天线口 10的随机波束成行传输方案发送广播消息给 UE。 当广播信道的参考 信号为 4天线 DMRS时， 该步骤可以为基于天线口 7、 天线口 9、 天线口 11 和天线口 13发送广播消息给用户设备， 也可以为基于天线口 8、 天线口 10、 天线口 12和天线口 14发送广播消息给用户设备。 以基于天线口 7、 天线口 9、 天线口 11和天线口 13发送广播消息给用户设备为例， 此时该步骤可以依次循 环使用天线口 7、 天线口 9、 天线口 11和天线口 13传输承载广播信道的符号 上用于传输广播信道的资源单元上承载的信号。
该步骤中， 当基站基于步骤 501确定的广播信道的参考信号为 DMRS的 传输方案发送广播消息给 UE时，不同小区可以基于不同的 DMRS天线口进行 传输。
例如， 小区 1和小区 2为相邻的两个小区， 小区 1采用天线口 7和天线口 9传输广播信道， 小区 2采用天线口 8和天线口 10传输广播信道。 由于不同天 线口之间相互正交，可以减小小区间干扰，对密集小区布网的场景尤其有好处。
其中， 当不同小区采用不同的天线口时，基站可以在同步信号和 /或发现信 号上承载指示本小区使用的天线口的信息， 以使得 UE在检测到同步信号和 / 或发现信号后，根据同步信号和 /或发现信号上承载的指示本小区使用的天线口 的信息， 获取传输广播信道的天线口， 从而避免 UE做盲检， 节省 UE检测广 播信道的时间， 提高广播信道的传输性能。 另外， 基站也可以将广播信道的参 考信号的 DMRS天线口信息加扰在广播信道的 CRC上。
其中， 当基站基于步骤 501确定的广播信道的参考信号为第一参考信号的 传输方案发送广播消息给 UE时， 基站基于第一参考信号的发射分集传输方案 发送广播消息给 UE。
其中， 当基站确定广播信道的参考信号为第一参考信号时， 可以采用天线 口 0和天线口 1传输第一参考信号， 也可以采用天线口 0、 天线口 1、 天线口 2 和天线口 3传输第一参考信号。
其中， 采用第一参考信号的发射分集传输方案时， 可以提高广播信道的传 输性能。
该步骤中， 基站还可以先采用雷德密勒 RM码对广播消息进行信道编码， 然后将编码后的广播消息映射到承载物理广播信道的资源单元上并发送给
UE。
步骤 503: UE确定广播信道的传输资源， 广播信道的传输资源包含广播 信道的参考信号和承载广播信道的符号；
其中， UE确定广播信道的传输资源包含的承载广播信道的符号， 包括： 确定承载广播信道的符号的个数为 1或 2。
其中，承载广播信道的符号可以为载波中心 6个物理资源块对上的一个或 者两个符号。
其中， 广播消息可以为下行系统带宽。
其中， 广播消息也可以为下行系统带宽和载波属性， 该载波属性用于指示 该载波为新载波类型。
其中，不同小区承载广播信道的符号都位于载波中心 6个物理资源块对上， 但不同小区对应载波中心 6个物理资源块对上的不同符号，对于每个小区对应 的符号，基站可以采用同步信道和 /或发现信号指示承载广播信道的符号的符号 索引， 由于不同的小区在不同符号上传输广播消息， 可以减小小区间干扰， 对 密集小区布网的场景尤其有好处。
其中， UE可以根据承载广播信道的载波的小区标识确定承载广播信道的 符号。 UE根据承载广播信道的载波的小区标识确定承载广播信道的符号可以 为 UE根据承载广播信道的载波对应的物理小区的物理小区标识确定承载广播 信道的符号。
其中， 载波对应的物理小区可以为指部署该载波的小区。
其中， 载波的物理小区标识可以为高层配置的。
其中， UE根据承载广播信道的载波的小区标识确定承载广播信道的符号 还可以为： UE根据承载广播信道的载波的虚拟小区标识确定承载广播信道的 符号。
其中， 虚拟小区标识是高层配置的， 不同物理小区可对应相同的虚拟小区 标识。

其中， UE 确定广播信道的传输资源包含的广播信道的参考信号可以为 DMRS, 也可以为第一参考信号。
其中， UE确定广播信道的传输资源包含的广播信道的参考信号为 DMRS 的方法和实施例 3中 UE确定广播信道的传输资源包含的广播信道的参考信号 为 DMRS的方法相同， 此处不再赘述。
其中， UE确定广播信道的传输资源包含的广播信道的参考信号为第一参 考信号的的方法和实施例 4中 UE确定广播信道的传输资源包含的广播信道的 参考信号为第一参考信号的的方法的方法相同， 此处不再赘述。
步骤 504: UE基于广播信道的传输资源， 获取广播信道承载的广播消息。 该步骤中， UE基于步骤 503确定的广播信道的传输资源， 获取广播信道 承载的广播消息。
例如， UE可以采用基于步骤 503确定的广播信道的参考信号对广播信道 进行译码， 获取广播信道承载的广播消息。 其中， 当广播信道的参考信号为 DMRS 时， 该基于 DMRS 的传输方案可以为基于 DMRS 的随机波束成行 (Random beamforming)或为基于 DMRS的发射分集。 例如， 当步骤 503中 UE 确定广播信道的参考信号为 DMRS, 且该 DMRS在天线口 7和天线口 9上传 输时， 该步骤 304UE可采用基于天线口 7和天线口 9的随机波束成行传输方 案对广播信道进行译码， 获取广播信道承载的广播消息， 具体可以为交替使用 天线口 7和天线口 9对承载广播信道的符号上用于传输广播信道的资源单元上 承载的信号进行译码。 由于天线口 7和天线口 9是采用 FDM的方式， 因而能 使得该广播信道对应的 DMRS 的频域密度较高， 从而提高该物理广播信道的 传输性能。 采用类似使传输 DMRS 的天线口中至少有两个天线口是频分复用 的思想， 该步骤也可以采用基于天线口 8和天线口 9的随机波束成行传输方案 对广播信道进行译码获取广播信道承载的广播消息、或采用基于天线口 8和天 线口 10的随机波束成行传输方案对广播信道进行译码获取广播信道承载的广 播消息、 或基于天线口 7和天线口 10的随机波束成行传输方案对广播信道进 行译码获取广播信道承载的广播消息。 当广播信道的参考信号为 4天线 DMRS 时， 该步骤可以为基于天线口 7、 天线口 9、 天线口 11和天线口 13发对广播 信道进行译码获取广播信道承载的广播消息， 也可以为基于天线口 8、 天线口 10、天线口 12和天线口 14对广播信道进行译码获取广播信道承载的广播消息。 以基于天线口 7、 天线口 9、 天线口 11和天线口 13发送广播消息给用户设备 为例， 此时该步骤可以依次循环使用天线口 7、 天线口 9、 天线口 11和天线口 13 对承载广播信道的符号上用于传输广播信道的资源单元上承载的信号进行 译码。
该步骤中， 当基站基于步骤 503确定的广播信道的参考信号的传输方案对广播 信道进行译码， 获取广播信道承载的广播消息时， 不同小区可以对应不同的 DMRS天线口。
其中， 当 UE确定广播信道的传输资源包含的广播信道的参考信号为第一 参考信号， UE采用基于该第一参考信道的发射分集对广播信道进行译码， 获 取广播消息。
该步骤中， UE还可以采用雷德密勒 RM码对广播信道承载的广播消息进 行译码， 获取广播信道承载的广播消息。 前提是广播信道上传输的广播信息也 采用 RM码进行编码。
其中， 广播消息可以为下行系统带宽。
其中， 广播消息也可为下行系统带宽和载波属性， 该载波属性用于指示该 载波为新载波类型。
其中， 在本发明实施例中， 广播信道可以为物理广播信道或增强的物理广 播信道。
需要说明的是， 本发明实施例中步骤 501和步骤 502为基站侧的步骤， 步 骤 503和步骤 504为 UE侧的步骤， 基站侧的步骤和 UE侧的步骤可以独立存 在， 也可以相互依赖存在。
通常， 基站侧按照广播信道的传输机制发送广播信道， UE侧按照相同的 广播信道的传输机制对广播信道进行接收， 由于基站和 UE采用的广播信道的 传输机制是相同的， 因而，基站侧的步骤与 UE侧的步骤通常是对应的。
例如， 当基站确定广播信道的参考信号为第一参考信号和承载广播信道的 符号为载波中心 6个物理资源块对上的一个符号时， 相应的， UE也确定广播 信道的参考信号为第一参考信号和承载广播信道的符号为载波中心 6个物理资 源块对上的一个符号； 当基站确定广播信道的参考信号为 DMRS 和承载广播 信道的符号为载波中心 6个物理资源块对上的两个符号时， 相应的， UE也确 定广播信道的参考信号为 DMRS和承载广播信道的符号为载波中心 6个物理 资源块对上的两个符号； 当基站确定承载广播信道的符号的个数为 1 时， UE 确定承载广播信道的符号的个数为 1; 当基站确定承载广播信道的符号的个数 为 2时， UE确定承载广播信道的符号的个数为 2。
在本发明实施例中，基站确定广播信道的传输资源为广播信道的参考信号 和承载广播信道的一个或者两个符号， 基站根据确定的广播信道的传输资源， 以第一参考信号为参考信号采用发射分集传输方案发送广播消息给 UE或者以 DMRS为参考信号采用随机波束成行传输方案发送广播消息给 UE, UE确定广 播信道的传输资源，基于广播信道的传输资源，获取广播信道承载的广播消息， 解决了 NCT上如何传输广播消息的问题； 另一方面， 由于所承载的广播消息 可以仅为下行系统带宽或下行系统带宽和载波属性， 减小了广播消息的信息比 特数， 降低了广播消息的编码比特， 从而提高了如下行系统带宽这类重要广播 消息的传输性能； 另一方面， 采用 RM码进行信道编码和译码， 也提高了广播 消息的编码性能， 从而提高广播消息的传输性能； 另一方面， 由于基站以第一 参考信号为参考信号采用发射分集传输方案发送广播消息， 或者以 DMRS 为 参考信号采用随机波束成行传输方案发送广播消息能够提高广播消息的传输 性能，同时由于不同的小区在不同符号上传输广播消息，可以减小小区间干扰， 提高广播消息的传输性能。 实施例 6
