Embodiment 1

[0024] refer to figure 1 , shows a flow chart of steps of a method for processing MTC information according to Embodiment 1 of the present invention.

[0025] This embodiment describes the MTC information processing method of the present invention from the MTC terminal side.

[0026] Step S102: the MTC terminal determines the length of the original information to be transmitted.

[0027] Step S104: The MTC terminal determines the number of times to repeat the original information according to a set rule according to the length of the original information and the length of a TB (Transmission Block, data transmission block) carrying the original information.

[0028] The original information is carried in a TB, and the number of repetitions of the original information is limited by the length of the TB. Therefore, it is necessary to consider the length of the original information and the length of the TB to determine the number of repetitions of the original information. The a...

Embodiment 2

[0037] Referring to FIG. 2 , it shows a flowchart of steps of a method for processing MTC information according to Embodiment 2 of the present invention.

[0038] This embodiment further optimizes the solution of the first embodiment, and still describes the MTC information processing method of the present invention from the side of the MTC terminal.

[0039] The MTC information processing method of this embodiment includes the following steps:

[0040] Step S202: the MTC terminal determines the length of the original information to be transmitted.

[0041] Step S204: The MTC terminal determines the value of repeating the original information according to the length of the original information and the length of the TB carrying the original information, according to the value indicated by the CQI (Channel Quality Indicator, Channel Quality Indicator) of the MTC, or the indication signaling sent by the base station. repeat times.

[0042] Wherein, the indication signaling sent...

Embodiment 3

[0050] refer to Figure 4 , shows a flow chart of steps of a method for processing MTC information according to Embodiment 3 of the present invention.

[0051] This embodiment describes the MTC information processing method of the present invention from the base station side.

[0052] The MTC information processing method of this embodiment includes the following steps:

[0053] Step S302: the base station receives the TB carrying the target information sent by the MTC terminal through the PDSCH.

[0054] Among them, the target information is generated by repeating the original information according to the number of repetitions; the number of repetitions is determined according to the length of the original information and the length of the TB carrying the original information, and according to the set rules.

[0055] Step S304: The base station performs de-repetition encoding and recovery on the target information to obtain the original information.

[0056] The base stati...

Abstract

The invention provides an information processing method and a terminal for MTC, a base station and a communication system. The information processing method for MTC comprises determining the length of raw information to be transmitted at an MTC terminal; according to the length of the raw information and the length of a data transmission block carrying the raw information, determining repetition times of the raw information according to a set rule; repeating the raw information according to the repetition times to generate target information; carrying the target information in the data transmission block; and using a physical downlink shared channel to transmit the data transmission block carrying the target information. By means of the information processing method and the terminal for MTC, the base station and the communication system, the error rate of data transmission of MTC terminals located at edges of cells during MTC communication is reduced, performances of MTC terminals located at edges of cells are improved, and the coverage of cells is enlarged.

Description

technical field [0001] The present invention relates to the technical field of MTC (Machine Type Communication, machine type communication), in particular to an MTC information processing method, an MTC terminal, a base station, and a communication system. Background technique [0002] 3GPP names M2M (Machine to Machine, machine-to-machine communication) as machine type communication, ie, MTC. MTC is a form of data communication in which one or more network entities do not require human participation. Compared with everyone's communication, MTC has the following communication characteristics: 1. Different market environments; 2. Not mainly voice services, but digital services , M2M business requirements are diverse; 3. Lower communication costs; 4. Compared with voice terminals, MTC communication terminals have a very large potential number, and the number of M2M devices is large; 5. Each terminal occupies very few network resources. However, the peak load of the M2M servic...
