Description

一种系统信息发送方法和装置 技术领域
本申请涉及但不限于移动通信技术领域。
背景技术
在LTE(Long Term Evolution，长期演进)系统中，UE(User Equipment，用户设备)在接入某小区前，需要先获取到该小区的系统信息，才能知道该小区是如何配置的，以便在该小区内正确的工作。小区是通过逻辑信道BCCH(Broadcast Control Channel，广播控制信道)向该小区内的所有UE发送系统信息的，逻辑信道BCCH会映射到传输信道BCH(Broadcast Channel，广播信道)和DL-SCH(Downlink share channel，下行共享信道)，其中，BCH只用于传输MIB(Master Information Block，主信息块)信息，并映射到物理信道PBCH(Physical Broadcast Channel，物理广播信道)，DL-SCH用于传输各种SIB(System Information Block，系统信息块)信息，并映射到物理信道PDSCH(Physical Downlink Shared Channel，物理下行共享信道)。LTE的PBCH信道每10毫秒(ms)发送一次，开销比较大，灵活性差。
UE通过检测PBCH，能得到以下信息：
(1)通过接收到的MIB可以知道小区的下行系统带宽、PHICH(Physical Hybrid Automatic Repeat Request Indicator Channel，物理混合自动重传指示信道)配置、系统帧号(System Frame Number，SFN)；
(2)小区特定的天线端口(cell-specific antenna port)的数目：1或2或4；
(3)用于L1/L2控制信号(control signal)，包括PCFICH(Physical Control Format Indicator Channel，物理控制格式指示信道)、PHICH、PDCCH(Physical Downlink Control Channel，物理下行控制信道)的传输分集模式(transmit-diversity scheme)：PBCH和L1/L2control signal都只能使用单天线传输或传输分集，如果使用传输分集，PBCH和L1/L2 control signal会使用相同的多天线传输分集模式。
随着智能终端的兴起及无线数据应用业务的丰富，无线通信系统中的数据用户数大幅增加，数据内容不再限于相关技术中的文字或者图像，未来用户对高清晰度视频、手机电视等多媒体业务的需求越来越多，导致无线网络流量呈现出爆炸式增长的态势。根据市场机构预测，未来10年，无线数据业务将增长500～1000倍，平均每年增长1.6～2倍，这对无线通信系统的网络容量提出了更高的要求。
面向2020年及未来，移动互联网和物联网业务将成为移动通信发展的主要驱动力。5G(5-Generation，第五代移动通信)将满足人们在居住、工作、休闲和交通等各种区域的多样化业务需求，即便在密集住宅区、办公室、体育场、露天集会、地铁、快速路、高铁和广域覆盖等具有超高流量密度、超高连接数密度、超高移动性特征的场景，也可以为用户提供超高清视频、虚拟现实、增强现实、云桌面、在线游戏等极致业务体验。与此同时，5G还将渗透到物联网及各种行业领域，与工业设施、医疗仪器、交通工具等深度融合，有效满足工业、医疗、交通等垂直行业的多样化业务需求，实现真正的“万物互联”。
5G将解决多样化应用场景下差异化性能指标带来的挑战，不同应用场景面临的性能挑战有所不同，用户体验速率、流量密度、时延、能效和连接数都可能成为不同场景的挑战性指标。从移动互联网和物联网主要应用场景、业务需求及挑战出发，可归纳出连续广域覆盖、热点高容量、低功耗大连接和低时延高可靠四个5G主要技术场景。
满足5G需求的方法有多种，主要包括：提升频谱效率、提高网络密度、增加系统带宽、智能业务分流、降低系统广播控制开销等，其中，降低系统广播控制开销需要灵活地适应5G中不同业务需求，满足系统设计“前向兼容性”的考虑，如果继续采用LTE相关的机制，无法满足要求。
