Abstract

The present invention relates to a method and device for narrowband wireless digital communication to reduce misjudgment of reverse signaling. The method includes: receiving and obtaining the first reverse signaling in a downlink time slot; Receive the second reverse signaling in the downlink time slot; compare the first reverse signaling with the preset number of second reverse signaling in order of reception, when the first reverse signaling is compared with one of the second reverse signaling When the reverse signaling is the same, it is determined that the first reverse signaling is valid, and when the first reverse signaling is different from the preset number of second reverse signaling, it is determined that the current first reverse signaling is invalid, and The first second reverse signaling obtained after the current first reverse signaling is used as the first reverse signaling, and the previous step is continued. By comparing the reverse signaling received by multiple downlink time slots, it is judged whether the reverse signaling is valid, and after the judgment is invalid, the subsequent reverse signaling is compared to effectively reduce the misjudgment rate of reverse signaling and improve Judgment efficiency.

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...
