Description

一种消息处理的方法、基站及终端Message processing method, base station and terminal 技术领域Technical field
本申请涉及但不限于移动通信技术领域，尤其涉及一种消息处理的方法、基站及终端。The present application relates to, but is not limited to, the field of mobile communication technologies, and in particular, to a message processing method, a base station, and a terminal.
背景技术Background technique
为了实现5G(5th Generation Mobile Communication System，第五代移动通信系统)目标：每区域1000倍的移动数据流量增长，每用户10到100倍的吞吐量增长，连接设备数10到100倍的增长，低功率设备10倍的电池寿命的延长和端到端5倍延迟的下降，5G中必须提出一些新的无线技术解决方案。其中，在毫米波频段使用大带宽(500M到1GHz)是解决未来数据业务吞吐量指数增长的主要解决方案。虽然在10G到100G的毫米波范围内仍有大量的闲置频段可用于通信，但毫米波频段由于在空气中传播的路损大、反射和散射现象严重，为了保证站点一定的覆盖范围，必须使用新的技术方案。由于毫米波频段波长在厘米量级，大规模天线的尺寸可以控制在合适范围。同时使用大规模天线和波束赋形技术可以有效提高系统的增益，有效解决高频通信中传播路损大等不利因素带来的一系列问题。在5G部署场景中，由于毫米波频段传播路损大，6G以上频段主要用于构建微基站(Small Cell)，用于城区热点区域的覆盖。而3G到6G频段主要用于构建宏基站，用来解决覆盖问题。对于热点区域中的微基站，驻留的用户数会随着时间的不同发生巨大的变化。In order to achieve the 5G (5th Generation Mobile Communication System) target: 1000 times of mobile data traffic per area increases, the throughput of 10 to 100 times per user increases, and the number of connected devices increases by 10 to 100 times. With 10 times longer battery life and 5x end-to-end delay for low-power devices, some new wireless technology solutions must be proposed in 5G. Among them, the use of large bandwidth (500M to 1GHz) in the millimeter wave band is the main solution to solve the future data traffic throughput index growth. Although there are still a large number of idle frequency bands available for communication in the millimeter wave range of 10G to 100G, the millimeter wave band must be used in order to ensure a certain coverage of the site due to the large path loss and reflection and scattering in the air. New technical solutions. Since the wavelength of the millimeter wave band is on the order of centimeters, the size of the large-scale antenna can be controlled to an appropriate range. At the same time, the large-scale antenna and beamforming technology can effectively improve the gain of the system, and effectively solve a series of problems caused by unfavorable factors such as large path loss in high-frequency communication. In the 5G deployment scenario, due to the large path loss of the millimeter wave band, the frequency band above 6G is mainly used to construct a small cell (Small Cell) for coverage of urban hotspots. The 3G to 6G frequency band is mainly used to construct a macro base station to solve the coverage problem. For micro base stations in hotspots, the number of users residing varies greatly over time.
