Problems solved by technology

At the same time, in the WorkItem of MTC in the R13 stage, UE power saving is a key consideration. Since MTC UE does not need to send data in most cases, it can save power by sleeping. When MTC UE wakes up from the sleep state, it performs uplink When data is sent, it is likely that there is no TA (Timing Advance, timing advance) or the previously stored TA has expired. At this time, the MTC UE directly sends on the PUSCH without random access, which will cause strong interference to other users

Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0020] In this embodiment, the MTC UE bandwidth is 1.4M and the dual-tone signal length is configured as 0.125ms as an example to illustrate the specific process of the MTC UE sending uplink data. The steps are as follows figure 1 As shown, the specific description is as follows:

[0021] 1. When the base station needs to trigger the device to report user data, it sends a paging message to the device. The message contains the information of the MTC UE being paged, and the MTC UE receives the paging message.

[0022] 2. The MTC UE acquires downlink ...

Abstract

The present invention provides an MTC uplink data transmission method. The method comprises: an eNB is configured to distribute uplink resource for an MTC UE, the MTC UE sends uplink data on the uplink source specialized by itself, the uplink data employs double-tone signals to perform transmission, and the frequency combination of the line frequency and column frequency of the double-tone signals is used for representing the bit information of the uplink data; and the eNB detects the double-tone signals of the uplink data sent by the MTC UE, and the frequency combination of the line frequency and column frequency of the double-tone signals is used for determining the bit information of the uplink data sent by the MTC UE. When the double-tone signals TA have deviation, own signals cannot be influenced, and other users' interferences are located in the controllable range.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an MTC uplink data transmission method. Background technique [0002] Machine Type Communication (MTC, Machine Type Communication) is a general term for a series of technologies and technology combinations that apply various communication networks and information perception and processing to realize data communication and interaction between machines and machines and between machines and humans. The existing MTC communication mechanism can be divided into Push and Pull. The so-called Push mechanism is that the MTC UE actively initiates communication to the network side and reports data; while the Pull mechanism is that the network side actively initiates communication and requires the MTC UE to report data. The two types of communication Among the methods, the Pull mechanism can allow the network side to control the communication flow, avoiding congestion caused by a large n...
