Data symbol transmission method and wireless device

A data symbol transmission method, comprising:

• determining, by a first wireless device, a location at which hardware switching needs to be performed in a current subframe and switching time of the hardware switching;
• configuring, by the first wireless device according to the switching time, a first guard period for a first data symbol corresponding to the location, wherein a length of the first guard period is greater than or equal to that of the switching time;
• using, by the first wireless device as a second data symbol, a data symbol in the subframe other than the first data symbol, and configuring a second guard period for the second data symbol, and in response to determining that the length of the first guard period is shorter than a length of a second guard period, configure the length of the first guard period to be identical to the second guard period;
• and
• sending, by the first wireless device, the subframe to a second wireless device;
• wherein the first wireless device is a base station, and the second wireless device is a terminal;
• or, the first wireless device is a terminal, and the second wireless device is a base station.

A non-transitory computer storage medium, comprising instructions, which, when executed by a computer, cause the computer to perform operations, the operations comprising:

• determining, a location at which hardware switching needs to be performed in a current subframe and switching time of the hardware switching;
• configuring, according to the switching time, a first guard period for a first data symbol corresponding to the location, wherein a length of the first guard period is greater than or equal to that of the switching time;
• using, as a second data symbol, a data symbol in the subframe other than the first data symbol, and configuring a second guard period for the second data symbol, and in response to determining that the length of the first guard period is shorter than a length of a second guard period, configure the length of the first guard period to be identical to the second guard period;
• and
• sending the subframe to a second wireless device.
