Abstract

Embodiments of the invention disclose a data transmission method and device, a base station and user equipment. The method includes obtaining channel quality information, the channel quality information being downlink channel quality information or uplink channel quality information; determining the time intervals between the time obtaining the channel quality information and service data resourcescheduling time, wherein the service data is downlink service data if the channel quality information is the downlink channel quality information, and the service data is uplink service data if the channel quality information is the uplink channel quality information; determining a target modulation and coding scheme (MCS) used by the service data according to the channel quality information, thetime interval and channel coherence time; and sending the target MCS to the user equipment. The data transmission of unauthorized band channels can be realized through the embodiments, and the reliability of unauthorized band data transmission can be enhanced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data transmission method, device, base station and user equipment. Background technique [0002] With the rapid growth of smart devices and increasing data traffic, the demand for network capacity is increasing exponentially. On the one hand, the use of new technologies can increase the capacity of mobile networks; on the other hand, increasing spectrum resources can also improve network performance. However, the development of new technologies is difficult to meet the growing demand for mobile data; limited and non-renewable spectrum resources are even more precious. While the scarcity of spectrum resources is becoming increasingly prominent, the utilization efficiency of spectrum resources is relatively low. License-free frequency bands There are a large number of spectrum resources available. With the advantages of LTE system centralized scheduling, in...
