Embodiment Construction
[0019] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Aiming at the problem of waste of uplink resources in the prior art, the inventors of the present invention found that when the quality of the uplink channel of the first terminal using TTI bundling is good, it usually only needs to use the redundant version of less than 4 subframes in one TTI bundling. Translate out the transpor...

The invention discloses a data transmission method. The data transmission method is applicable to base stations and includes: responding to a first terminal in a TTI (transmission time interval) bundling mode to transmit a redundancy version of a same transmission block in consecutive uplink sub-frames in a preset quantity, and if the fact that the transmission block can be decoded according to the consecutive uplink sub-frames in a quantity smaller than the preset quantity can be determined, instructing a second terminal not in the TTI bundling mode to perform uplink transmission on a same PRB (physical resource block) in the rest sub-frames along with the first terminal, and working out corresponding signals when the transmission block of the first terminal performs uplink transmission in the rest sub-frames; after uplink mixed signals transmitted on the same PRB by the first terminal and the second terminal are received, removing the signals corresponding to the transmission block of the first terminal from the uplink mixed signals to obtain uplink signals transmitted in the rest sub-frames by the second terminal. In addition, the invention further discloses a data transmission device and a data transmission system.
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] In the physical layer of the new generation TD-LTE mobile communication system, OFDMA technology (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) is used in the downlink direction, and SC-FDMA technology (Single-Carrier Frequency Division Multiple Access) is used in the uplink direction. Multiple Access, single carrier frequency division multiple access). In this way, allocating resources for terminals connected to the system can be performed in two dimensions of time domain and frequency domain. In the time domain, the largest unit of resource division is a radio frame with a length of 10ms, and each radio frame includes 10 subframes with a length of 1ms. In the frequency domain, each physical cell uses a carrier, and its frequency band is divided into mu...
