Method for indicating mobile terminal to control channel information and method for controlling channel bland detection

Abstract

The invention discloses a method for indicating a mobile terminal to control channel information and a method for controlling channel blind detection. The method for controlling channel bland detection comprises the steps: ensuring a modulating method of a next time slot mobile terminal service channel by a node B; numbering a control channel unit CCE which corresponds to the mobile terminal service channel; numbering the corresponding control channel unit with the same modulating method of the mobile terminal service channel into the same continuous control channel unit range; indicating control channel unit ranges and corresponding modulating methods of the service channel; and carrying out the blind detection sequentially in the control channel unit ranges by the mobile terminal according to the indication. The method can decrease the blind detection time, the blind diction time and the control signaling overhead of the mobile terminal and reduce the treating processes and the power consumption of the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for indicating control channel information of a mobile terminal and a control channel blind detection method. Background technique [0002] LTE (Long Term Evolution, long-term evolution) system and IMT-Advanced (Advanced International Mobile Telecommunications, advanced international mobile communication) 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 on the user equipment (UE), the control channel usually adopts TDM (Time Division Multiplex, time division multiplexing) mode, that is to say, the control channel and the traffic channel 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 sym...

Problems solved by technology

The above-mentioned method of using a fixed CCE combination structure to indicate UE control channel information can reduce the number of blind detection times of some UEs to a certain extent, but the effect of reducing blind detection time is not ideal, and it cannot take into account other performances of the system (such as reducing control signaling overhead)
