Embodiment
Scheme of the prior art is solved in the case of dynamic TDD, it is impossible to the problem of normal transmission control information, this hair Bright embodiment provides the sending, receiving method and relevant apparatus of a kind of control information.Pass through side provided in an embodiment of the present invention Case, allows control information and business datum to be transmitted respectively in the subframe determined, ascending control information only it is determined that It is transmitted on the sub-frame of uplink gone out, and Downlink Control Information is also only passed on the descending sub frame or special subframe determined It is defeated, improve the efficiency of transmission of up-downgoing control information, it is to avoid in the case of dynamic TDD, up-downgoing control information can not be just Situation about often transmitting, while the complexity of the HARQ sequential in the case of design dynamic TDD can also be reduced.
The basic thought of the scheme provided in the embodiment of the present invention is：
For up-link, the sub-frame of uplink in TDD-LTE system is divided into two groups：Upload control subframe and upstream data Subframe, wherein, upload control subframe can be to be both configured to up son in specified ascending-descending subframes configuration mode set The subframe of frame, it includes control zone and data field, or only control zone.Upstream data subframe can be above and below currently employed Other sub-frame of uplink in row sub-frame configuration mode in addition to upload control subframe, it only includes data field.Specifically, upload control The data field that control zone in subframe is used in transmitting uplink control information, upload control subframe or upstream data subframe is used for passing Defeated uplink business data.
For downlink, the descending sub frame in TDD-LTE system is divided into two groups：Descending control subframe and downlink data Subframe, wherein, descending control subframe can be to be both configured to descending son in specified ascending-descending subframes configuration mode set The subframe of frame or special subframe, it includes control zone and data field, or only control zone.Down data subframes can be current Other descending sub frames in the ascending-descending subframes configuration mode of use in addition to descending control subframe, it only includes data field.Wherein, DwPTS parts in special subframe can also be used as descending sub frame.Specifically, the control zone in descending control subframe is used for transmitting Data field in Downlink Control Information, descending control subframe or down data subframes is used for transmission services data.
It is former to the main realization of technical scheme of the embodiment of the present invention with reference to each accompanying drawing based on above-mentioned basic thought Reason, embodiment and its beneficial effect that should be able to be reached is explained in detail.
Embodiment one：
