Embodiment Construction

[0051] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0052] method embodiment

[0053] According to an embodiment of the present invention, a method for controlling channel adaptive transmission is provided. image 3 is a flowchart of a method for controlling channel adaptive transmission according to an embodiment of the present invention, such as image 3 As shown, the method includes:

[0054] Step S302, setting or not setting the extended control information in the enhanced control channel format indication in the transmission information including the control channel format indication information;

[0055] Step S304, when transmitting the above transmission information, implicitly indicate whether the transmission information sets the extended control information in the enhanced control channel format indication according to a predetermined implicit representation manner.

Abstract

The invention provides a method for controlling self-adaptive transmission of channels and a device thereof, wherein, the method includes the steps: extension control information in the format indication of an enhanced control channel is configured or not configured in the transmitting information including the format indicating information of a control channel; when the transmitting information is transmitted, whether the extension control information in the format indication of the enhanced control channel is configured in the transmitting information is implicitly represented according to a scheduled implicit expression mode. The method and the device of the invention realize good self-adaptive transmission of two structures of CCFI and E-CCFI, thus solving the forward-backward compatibility problem of the system.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for adaptive transmission of a control channel. Background technique [0002] LTE (Long-Term Evolution, long-term evolution) / LTE-Advanced system and IMT-Advanced (International Mobile Telecommunications, International Mobile Communications) system are based on OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology. In the OFDM system, it is a time-frequency two-dimensional data form. In order to save power at the UE (User Equipment, user equipment), the control channel usually adopts TDM (Time Division Multiplex, time division multiplexing) mode, that is, the control channel and the traffic channel are in the They are separated in time, for example, there are 14 OFDM symbols in a subframe, the first 3 OFDM symbols are used as control channels, and the last 11 OFDM symbols are used as traffic channels.
