Embodiment 1

[0082] image 3 It is a flowchart of a control channel transmission method according to an embodiment of the present invention. This method is applied to network side devices, such as image 3 shown, including:

[0083] Step S302, acquiring indication information for indicating the terminal type;

[0084] Step S304, when the terminal type indicated by the indication information is the first terminal type, sending a control channel to the terminal of the first terminal type in multiple subframes.

[0085] Through the above processing steps, since the terminal type indicated by the indication information indicating the terminal type is the first terminal type, the technical means of sending the control channel to the terminal on multiple subframes is adopted, therefore, the network side in a low coverage environment can It can distinguish terminals for control channel transmission to ensure that terminals that need coverage improvement can correctly receive the control inform...

Embodiment 2

[0151] This embodiment corresponds to Embodiment 1, and is described on the terminal side.

[0152] Figure 8 It is a flowchart of a control channel transmission processing method according to an embodiment of the present invention. This method is applied to terminals such as Figure 8 shown, including:

[0153] Step S802, acquiring indication information for indicating the terminal type;

[0154] Step S804, when the terminal type indicated by the indication information is the first terminal type, detect the control channel in multiple subframes.

[0155] In this embodiment, when the indication information indicates that the terminal type is the second terminal type, the control channel is detected on a single subframe. In this embodiment, 1 or 2 may be used to identify the terminal type, for example, "1" is used to indicate the first terminal type, and "2" is used to indicate the second terminal type.

[0156] In this embodiment, obtaining the indication information used...

Embodiment 3

[0220] In order to ensure the correct transmission of the control channel of the MTC device or other terminals in the low coverage environment, the present invention proposes a control channel transmission method and device, which mainly solves the problem that the base station in the low coverage environment can distinguish the terminal equipment for the transmission of the control channel , and the terminal that needs to improve the coverage can correctly receive the control information sent by the base station to ensure the data transmission of the terminal.

[0221] In this embodiment, under the FDD system, the control channel transmission adopts the bundling transmission method provided by the present invention in detail.

[0222] Specific processing steps on the base station side, such as Figure 10 shown, including:

[0223] Step S1002, the base station side judges whether the control channel transmission needs to be bundled and repeated. The base station judges that ...

Abstract

The invention provides a control channel transmitting method and device, a transmitting processing method and device, a network side device and a terminal, wherein the transmitting method is applied to the network side device. The method comprises the steps that indicating information for indicating the type of a terminal is obtained; when the terminal type indicated by the indicating information is a first terminal type, the control channel is sent to the terminal of the first terminal type on multiple subframes. By the adoption of the technical scheme, the technical problems that in the relevant technologies, a downlink control channel cannot be sent repeatedly and the like are solved, so that the network side can distinguish the terminal to conduct control channel sending under a low-covering environment so as to guarantee that the terminal which has the demand of covering improvement can receive correctly the control information sent by the base station, and data transmitting of the terminal can be guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control channel transmission, a transmission processing method and device, network side equipment, and a terminal. Background technique [0002] Machine Type Communication (MTC for short) User Equipment (User Equipment or Terminal for short), also known as Machine to Machine (M2M for short) user communication equipment, is currently the main application of the Internet of Things form. In recent years, more and more mobile operators Suppliers choose LTE / LTE-A as the evolution direction of broadband wireless communication systems. MTC multi-type data services based on LTE / LTE-A will also be more attractive. [0003] The existing LTE / LTE-A system is based on the dynamic scheduling of each subframe for transmission, and its frame structure is as follows figure 1 and figure 2 shown. [0004] figure 1 It is a schematic diagram of a frame structure of a frequency division du...
