Problems solved by technology

[0008] However, in the same time period, the times of CCA and IDP appearing in radio frames of different lengths are not equal, and the number of times that different eNBs occupy the channel according to the detection of CCA in the same time is bound to be different, which leads to different channel resource occupancy. fair

Abstract

Disclosed are a data transmission method for a wireless network and a network node, which are used for the network node to configure the time domain length of a wireless frame on an unlicensed spectrum, so that different network nodes can occupy a channel, so as to achieve the fairness of network resource occupancy. The method of the embodiments of the present invention comprises: a network sending node determines the time domain length of the next one or more wireless frames of a current wireless frame on an unlicensed spectrum; the network sending node configures, according to the time domain length of the next one or more wireless frames, the next one or more wireless frames; and when an idle channel is detected via a CCA, the network sending node sends the configured next one or more wireless frames to a network receiving node.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless network data transmission method and a network node. Background technique [0002] The Long Term Evolution (LTE) system and the Long Term Evolution-Advanced (LTE-A) system adopt Orthogonal Frequency Division Multiplexing (OFDM) technology, and the minimum resource unit for data transmission is A resource element (Resource Element, RE) corresponds to one OFDM symbol in the time domain and one subcarrier in the frequency domain; on this basis, a resource block (Resource Block, RB) consists of multiple consecutive OFDM symbols in the time domain and frequency domain Consecutive subcarriers on the domain are the basic unit of resource scheduling. [0003] Further expanding the bandwidth is a direct and effective way to increase the network capacity. However, the existing LTE and LTE-A systems both work on the licensed spectrum. On the one hand, the available licensed spectrum re...
