INFORMATION TRANSMISSION METHOD, TERMINAL DEVICE, NETWORK DEVICE AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/145664

Kind Code:

A1

Abstract:

Disclosed are an information transmission method, terminal device, network device and device. The method comprises: modulating, by a terminal device, encoded hybrid automatic repeat request (HARQ) information according to a codebook to generate a HARQ modulation symbol, the HARQ modulation symbol comprising at least one non-zero HARQ modulation symbol and a zero HARQ modulation symbol, the codebook comprising at least two codewords, and the codewords being multi-dimensional complex vectors and being used to indicate a mapping relationship between a bit and the at least two modulation symbols; and transmitting the HARQ modulation symbol to a network device. In an embodiment of the present invention, the encoded HARQ information is modulated according to the codebook, such that a plurality of terminal devices decode correctly at a network device side when using the same time-frequency resource to transmit the HARQ information. Therefore, the embodiment of the present invention can transmit the HARQ information in a system in which the plurality of terminal devices use the same time-frequency resource, thus improving reliability of information transmission.
