Wireless communication method and device

A wireless communications method, comprising:

• receiving, by a terminal, first information sent by a network device, wherein the first information is used to instruct the terminal to switch an uplink transmit antenna, and the first information is determined based on a time interval threshold for switching an uplink transmit antenna by a terminal, a basic parameter set used when the terminal uses the uplink transmit antenna to send a signal, and a configuration of a slot or a mini slot;
• and
• determining, by the terminal in response to the first information, whether to switch the uplink transmit antenna.

A network device, comprising a processing unit and a communication unit, wherein:

• the processing unit is configured to determine a time interval threshold for performing frequency hopping by a terminal during transmission of a first signal, a basic parameter set used by the terminal to transmit first signal, and a configuration of a slot or a mini slot;
• and
• the communication unit is configured to send first information according to the time interval threshold, the basic parameter set, and the configuration of the slot or mini slot, wherein the first information is used to instruct the terminal to perform or not to perform frequency hopping during transmission of the first signal.
