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, acquiring the number of online user equipments;

[0055] Step S304, judging whether the quantity is more than a preset value;

[0056] Step S306, if it is not more than the preset value, then only set the control channel format indication information in the transmission information; if it is more than the predetermined value, set the control channel format indication information and the extended control channel format indication information in the transmission information contro...

Abstract

The invention provides a control channel self-adaptive transmission method and a device thereof. The method comprises: obtaining the quantity of equipment of online users; judging whether the quantity is more than a preset value; if the quantity is no more than the preset value, only indicating information of a control channel format is arranged in the transmission information; if the quantity ismore than the preset value, the indicating information of the control channel format is arranged in transmission information and extended control information in the control channel format indication is increased. The method of the control channel self-adaptive transmission and the device thereof reach the self-adaptive transmission of two structures of CCFI and E-CCFI, thus solving the problem ofthe system compatibility forwardly and the backwardly.

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.
