Abstract

The embodiment of the present invention discloses a data symbol transmission method and a wireless network device, wherein the wireless network device includes: an information determination unit, configured to determine the position in the current subframe where hardware switching is required and the switching of the hardware switching time; a configuration unit configured to configure a first guard band for the first data symbol corresponding to the position according to the switching time, and the length of the first guard band is greater than or equal to the switching time; the configuration unit is also A data symbol other than the first data symbol in the subframe is used as a second data symbol, and a second guard band is configured for the second data symbol; a sending unit is used to send another wireless network device The subframe is sent. This solution can improve resource utilization and increase system capacity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data symbol transmission method and wireless network equipment. Background technique [0002] In a broadband communication system, when a receiver receives data, it generally performs frequency domain equalization to combat channel frequency domain selective fading caused by multipath. When the receiver performs frequency domain equalization, it must ensure that the received previous symbol has no intersymbol interference to the subsequent symbol, which requires a guard band to be reserved before each symbol to resist the intersymbol interference of the previous symbol. Common guardband design methods include a cyclic prefix (CP for short) method, a zero prefix (ZP for short) method, and a zero tail (ZT for short) method. In addition, in order to reduce the power consumption of the base station and user equipment (referred to as "UE"), beamforming (beamforming, referred...
