Problems solved by technology

The main system information in every 40ms remains unchanged, and the system frame number (SFN) in the next main system information will change, so that the data of the broadcast channel cannot improve the coverage performance through long time domain repetition
Although smart meter reading MTC devices deployed in low-coverage environments can tolerate large delays, so that control signaling such as resource configuration and data transmission can ensure transmission performance through multiple repeated transmissions in the time domain, however, due to The poor information transmission performance of the main system will cause such MTC equipment to fail to communicate with the base station system normally
In order to reduce the cost of fixed-installed smart meter reading MTC terminal equipment, such MTC terminal equipment only supports 1.4MHz system bandwidth

Embodiment 1

[0138] In this embodiment, under the frequency division duplex (FDD, Frequency Division Duplexing) or time division duplex (TDD, Time Division Duplexing) system, it is mainly aimed at the cycle period whose interval is the system frame number, and repeats the transmission on the subframe of a single wireless frame. The system frame number indicates the scene of the information.

[0139] The specific processing steps on the base station side are as follows: figure 2 shown, including:

[0140] Step 201: the base station sets X resource positions for carrying system frame number indication information in a cycle period of system frame number information;

[0141] Here, each resource location consists of a single radio frame, such as Figure 5 , Image 6 As shown, in a cycle period of a system frame number, the base station sets a resource position for carrying the system frame number indication information, and in two adjacent system frame number cycle periods, the resource p...

Embodiment 2

[0153] For the FDD or TDD system, this embodiment is mainly aimed at the scenario where the system frame number indication information is repeatedly sent on each radio frame in the cycle period of the system frame number.

[0154] The specific processing steps on the base station side are as follows: figure 2 shown, including:

[0155] Step 201: the base station sets X resource positions for carrying system frame number indication information in a cycle period of system frame number information;

[0156] Here, each resource location consists of a single radio frame, such as Figure 7 As shown, in a cycle period of system frame number information, the base station sets 1024 resource positions 701 for carrying system frame number indication information, that is, each resource position 701 is on each radio frame in the system frame number cycle period.

Embodiment 3

[0165] In this embodiment, under the FDD or TDD system, the interval is mainly 2 10-Y A scenario in which system frame sequence number indication information is repeatedly sent on a single radio frame of (0<Y<10) radio frames.

[0166] The specific processing steps on the base station side are as follows: figure 2 shown, including:

[0167] Step 201: the base station sets X resource positions for carrying system frame number indication information in a cycle period of system frame number information;

[0168] Here, each resource location consists of a single radio frame, such as Figure 8 , 9 Shown, X=2 Y =16, 16 resource positions for carrying system frame number indication information are distributed at equal intervals within the cycle period of the system frame number, and the interval of the resource positions is a preset fixed wireless frame interval P=2 10-Y = 64 radio frame lengths.

[0169] Step 202: In the cycle period of each system frame number information, t...

Abstract

The invention discloses a method for transmitting system frame number information. In a cycle period of system frame number information, a base station sets X resource positions for carrying system frame number indication information; In the above, the base station transmits the system frame number indication information on at least one resource position; the terminal detects the system frame number indication information transmitted on each resource position within the cycle period of the system frame number information, obtains the system frame number of the current frame, and calculates The system frame number of the subsequent wireless frame; the present invention also discloses a device and system for transmitting system frame number information at the same time. Through the scheme of the present invention, the MTC terminal equipment of the intelligent meter reading class deployed in a low-coverage environment can be improved. Coverage performance, on the premise of not adding additional sites and relay station deployment, to ensure the normal communication requirements of MTC terminal equipment.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, device and system for transmitting system frame number information. Background technique [0002] MTC User Equipment (MTC UE, MTC User Equipment), also known as M2M user communication equipment, is the main application form of the Internet of Things at the present stage. Low power consumption and low cost are important guarantees for its large-scale application. Smart metering (smart metering) devices are one of the most typical applications of MTC devices. Most smart meter reading MTC devices are fixedly installed in low-coverage performance environments such as basements. In order to ensure that such MTC equipment can maintain normal communication with the base station system, it is usually necessary to deploy additional sites, relays and other equipment, which will undoubtedly greatly increase the deployment cost of operators. For this reason, companies...
