Embodiment Construction

[0070] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0071] Such as figure 1 As shown, an embodiment of the present invention provides a method for transmitting control information, including:

[0072] Step 11: Determine control information. The control information includes at least: a first characteristic domain and a second characteristic domain; and the bit value of the first characteristic domain is used to indicate the function and length of the second characteristic domain;

[0073] Step 12: Send the control information to the terminal device.

[0074] In the above-mentioned embodiment of the present invention, the format of the control information is modified, and the bit value of the first characteristic field is used to indicate the function and length of the second characteristic field...

Abstract

The invention provides a transmission method, a receiving method, a base station and a terminal of control information. The method comprises: determining control information, wherein the control information comprises at least a first feature field and a second feature field, and a bit value of the first feature field is used to indicate a function and a length of the second feature field; and transmitting the control information to the terminal device. The embodiments of the invention dynamically indicate the function and length of the second feature field by the bit value of the first featurefield of the control information, so that the control information can effectively support dynamic configurations of multiple transmission modes and transmission parameters.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method, receiving method, base station and terminal of control information. Background technique [0002] In the existing LTE (Long Term Evolution) system, the DCI (Downlink Control Information, downlink control information) sent by the base station to the user can be used to schedule downlink data transmission, uplink data transmission, and random access resource configuration of the user. Downlink control information includes multiple DCI formats, specifically: Format0 / 1 / 1A / 1B / 1C / 1D / 2A / 2B / 2C / 2D / 3 / 3A / 4, etc. Specifically, each DCI format corresponds to a transmission mode and a resource mapping mode that are not so-so, and the function of the fixed position bit field is also pre-configured, as shown in Table 1. [0003] Table 1 Summary of DCI format in LTE system [0004] DCI format Length (bit) DCI use Format 0 31Physical uplink shared channel PU...
