Embodiment Construction

[0053] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0054] method embodiment

[0055] 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:

[0056] Step S302, setting or not setting the extended control information in the E-CCFI in the transmission information including the control channel format indication information;

[0057] Step S304, creating indication information for indicating whether the extended control information in the E-CCFI is set in the transmission information;

[0058] Step S306, transmitting indication information and transmitting information.

[0059] This embodiment is applied to the transmitting end, and adopts ...

Abstract

The present invention provides a control channel self-adapting transmitting method and device, wherein, the method includes: setting or not setting the control information reinforcing extension in the control channel format indication in the transmitting information that includes the control channel format indication; creating the indication information for indicating whether the control information reinforcing extension in the control channel format indication is set up in the transmitting information; transmitting the indication information and transmitting information. The present invention reaches the good self-adapting transmission of two CCFI and E-CCEI structures, thereby resolving the forward and backward direction compatible problem of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a control channel adaptive transmission method and device. 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. [0003] In the ...
