Abstract

The embodiment of the invention discloses a method for transmitting a wireless frame. The method comprises the following steps: determining configuration information of the wireless frame; and performing uplink transmission of the wireless frame according to the configuration information of the wireless frame, wherein the wireless frame comprises at least three special sub-frames. Correspondingly, the embodiment of the invention further discloses a wireless network device. By adoption of the method disclosed by the invention, the number of the sub-frames applied to uplink transmission in the wireless frame can be increased, and then the number of the sub-frames used for sending detection signals is increased, thereby improving the timeliness of obtaining a downlink channel state.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless frame transmission method and wireless network equipment. Background technique [0002] With the evolution of wireless communication technology, in the future 5G (the 5th Generation, fifth generation mobile communication technology) system, an important feature is to introduce more transmission antennas, such as distributed MIMO (Multiple -Input Multiple-Output, multiple input multiple output) system, or a Massive MIMO system based on a large-scale antenna group. In downlink data transmission, the performance of MIMO transmission depends on the acquisition of the downlink channel state, that is, the more time-sensitive the acquisition of the downlink channel state is, the better the performance of MIMO transmission will be. [0003] In a TDD (Time Division Duplexing) system, since the uplink and downlink channels use the same frequency, that is,...
