阅读说明：本技术 一种时分双工通信方法和装置 (Time division duplex communication method and device ) 是由 刘鹏 蔡志龙 于 2019-05-16 设计创作，主要内容包括：本申请实施例公开了一种时分双工通信方法和装置,涉及通信技术领域,解决了现有技术中TDD切换的速度较慢,无法支持5G场景下的多种子载波间隔类型共存和切换,导致数据的传输效率较低等问题。具体方案为：射频设备获取基带设备发送的第一图谱索引和第一子载波间隔类型；第一图谱索引用于索引一个时隙内的每个正交频分复用OFDM符号对应的第一图谱类型；射频设备基于第一图谱索引和第一子载波间隔类型,配置第一时隙；其中,第一时隙为第一子载波间隔类型对应的时隙,第一时隙内的上下行指示是以第一时隙内的正交频分复用OFDM符号为转换点进行切换的；射频设备基于第一时隙进行数据传输。(The embodiment of the application discloses a time division duplex communication method and device, relates to the technical field of communication, and solves the problems that in the prior art, the TDD switching speed is low, coexistence and switching of multiple subcarrier interval types under a 5G scene cannot be supported, the data transmission efficiency is low, and the like. The specific scheme is as follows: the radio frequency equipment acquires a first map index and a first subcarrier interval type sent by the baseband equipment; the first map index is used for indexing a first map type corresponding to each Orthogonal Frequency Division Multiplexing (OFDM) symbol in one time slot; configuring, by the radio frequency device, a first time slot based on the first map index and the first subcarrier interval type; the first time slot is a time slot corresponding to the first subcarrier interval type, and uplink and downlink indications in the first time slot are switched by using an Orthogonal Frequency Division Multiplexing (OFDM) symbol in the first time slot as a switching point; the radio frequency device performs data transmission based on the first time slot.)
