Abstract
Description
technical field
[0001] The present invention relates to the communication field, in particular to a data transmission method, device and system. Background technique
[0002] The LTE (Long Term Evolution, Long Term Evolution) system supports Time Division Duplexing (Time Division Duplexing, TDD) mode, in which the uplink (UL, Uplink) and downlink (DL, Downlink) use different frequency carriers of the same frequency same time slot. The LTE TDD system can semi-statically adjust the uplink-downlink configuration (Uplink-Downlink Configuration) according to different service types to meet the asymmetric uplink-downlink service requirements.
[0003] In the existing LTE technology, which uplink-downlink ratio is used is semi-statically configured, and the configured uplink-downlink ratio may not match the instantaneous service type, so resources cannot be effectively utilized. In order to match the actual uplink and downlink ratio with the type of instantaneous service and make...
