Abstract

The invention provides a method for transmitting synchronous hybrid automatic repeat request feedback data, which comprises the step that: when resources, on a downlink subframe, used for transmitting the synchronous hybrid automatic repeat request feedback data are occupied by other configured services, a base station transmits the synchronous hybrid automatic repeat request feedback data on the later downlink subframe which has no conflict with the other services. By adopting the technical scheme of the invention, the problem that the base station has conflict with the other services when transmitting the synchronous hybrid automatic repeat request feedback data is avoided; and the method is easy to implement, and particularly has no need of additional signaling cost or resource cost when a terminal has known the configuration situation of other services.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for transmitting synchronous Hybrid Automatic Repeat reQuest (HARQ) feedback data. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services have emerged, and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertising, online education, interactive games, etc. On the one hand, it meets the ever-increasing business demands of mobile users, and at the same time brings new business growth points for mobile operators. These mobile multimedia services require multiple users to receive the same data at the same time. Compared with general data, they have the characteristics of large data volume, long duration, and delay sensitivity. [0003] In order to effect...
