上行子载波间隔指示方法、基站及终端技术

本发明专利技术实施例提供一种上行子载波间隔指示方法、基站及终端，基站确定用于指示自身支持的第一上行子载波间隔的指示信息，并根据指示信息与终端通信。通信过程中，向终端指示自身支持的第一上行子载波间隔，使得终端后续根据该第一上行子载波间隔确定自身支持的第二上行子载波间隔；或者，接收终端发送的携带第二上行子载波间隔的信息，即接收终端的指示，从而获知终端发送上行信号将要采用或终端支持的第二上行子载波间隔，使得终端在后续发送上行信号的过程中，采用合适的上行子载波间隔并发送上行信号，进而使得基站能够正确解调终端发送的上行信号。

Uplink subcarrier spacing indication method, base station and terminal

The embodiment of the invention provides an uplink subcarrier interval indication method, a base station and a terminal, which determine the indication information for indicating the first uplink subcarrier interval supported by itself and communicate with the terminal according to the indication information. In the communication process, the terminal is instructed to support a first uplink subcarrier interval of its own, so that the terminal determines a second uplink subcarrier interval of its own support according to the first uplink subcarrier interval subsequently; or, the information transmitted by the receiving terminal carrying the second uplink subcarrier interval, i.e. the indication of the receiving terminal, is received so as to be informed. The terminal transmits the uplink signal by adopting or supporting the second uplink subcarrier interval, so that the terminal adopts the appropriate uplink subcarrier interval and transmits the uplink signal during the subsequent transmission of the uplink signal, thereby enabling the base station to correctly demodulate the uplink signal transmitted by the terminal.
