Embodiment Construction

[0061] In order to make the purpose, technical solution and advantages of this embodiment clearer, the technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiment is the embodiment of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0062] This embodiment firstly provides a link detection method for narrowband transmission, see figure 1 ,include:

[0063] Step 101: the base station judges whether a transmission failure event occurs in the terminal.

[0064] For example, in this embodiment, the base station's determination of whether the terminal has a transmission failure event may include: determining whether the terminal meets the first c...

Abstract

The invention provides link detection methods for narrow-band transmission, a communication device and a terminal. The method in one embodiment comprises the steps that a base station determines whether a failed transmission event occurs at the terminal; and when the base station determines that the failed transmission event occurs at the terminal, the base station enters a scheduling backoff status, and the base station schedules the terminal preferentially when exiting the scheduling backoff status. According to the method, the transmission quality of a downlink can be learned according to determination of the failed transmission event, so that the scheduling transmission manner of the base station is determined. Through adoption of the method, unnecessary data transmission cost can be reduced, the transmission quality can be improved, the channel recovery condition can be responded timely, and data transmission delay can be prevented.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a link detection method for narrowband transmission, a communication device and a terminal. Background technique [0002] The design of wireless communication networks is limited by the available frequency bands. For systems that have allocated continuous and large-scale bandwidth, various control channels and traffic channels can be designed more easily. However, for frequency band resources with discrete available frequency bands and each discrete available frequency band is relatively narrow, how to reasonably design various channels and how to make full use of discrete narrowband resources is more difficult than that of broadband systems. Limited by the amount of frequency domain resources that narrowband bandwidth can provide, considering factors such as transmission delay and control channel overhead, narrowband systems can provide less effective information transmissi...
