Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] In one embodiment, such as figure 1 As shown, a method for narrowband wireless digital communication to reduce reverse signaling misjudgment in a preferred embodiment of the present invention includes the following steps:

[0025] Step S100, receiving and obtaining first reverse signaling in a downlink time slot.

[0026] Step S200, receiving second reverse signaling in several downlink time slots after the first reverse signaling.

[0027] Ste...

Abstract

The invention relates to a method and a device for reducing reverse signaling misjudgment in narrow-band wireless digital communication, and the method comprises the steps: a first reverse signaling is received and obtained in a downlink time slot; a second reverse signaling is received and obtained in a plurality of downlink time slots after the first reverse signaling; comparison is performed between the first reverse signaling and the preset quantity second reverse signalings according to the receiving sequence successively, if the first reverse signaling is same with one of the second reverse signaling, the first reverse signaling is effective is determined, if the first reverse signaling is different with the preset quantity of second reverse signalings, the current first reverse signaling is ineffective is determined, and a first second reverse signaling acquired after the current first reverse signaling serves as the first reverse signaling. According to the invention, if the reverse signaling is effective is determined through comparing reverse signalings received by a plurality of downlink time slots, after the ineffective reverse signaling is judged, the comparison between following reverse signalings is performed, the misjudgment rate of the reverse signalings can be effectively reduced, and the judgment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of narrowband wireless digital communication, in particular to a method and device for reducing reverse signaling misjudgment in narrowband wireless digital communication. Background technique [0002] In DMR (Digital Mobile Radio, digital mobile radio) / PDT (Professional Digital Trunking, digital trunking) digital mobile communication system, in order to implement some control on the source sender, such as power control and transmission control, the base station and the mobile station need to send The transmitting source sends reverse channel RC signaling. [0003] Among them, there are three kinds of reverse channel signaling: embedded reverse channel signaling, dedicated reverse channel signaling and independent reverse channel signaling. The embedded reverse channel signaling and dedicated reverse channel signaling are used for the downlink channel, and the independent reverse channel signaling is used f...
