A paging message transmission method and device

Abstract

Disclosed are a paging message transmission method and an apparatus. The method comprises: determining a total number of repeated transmission times M of a paging message in a paging cycle T and a number of repeated transmission times n on each radio frame; determining a start reference radio frame time difference configuration parameter in a start reference radio frame calculation formula and notifying a UE of the determined start reference radio frame time difference configuration parameter, wherein a start reference radio frame time difference D corresponding to the determined start reference radio frame time difference configuration parameter is not smaller than ┌M / n┐ radio frames; determining a start reference radio frame of the paging message based on the determined start reference radio frame time difference configuration parameter; determining a subframe where paging message transmission is located based on the determined start reference radio frame, M and n; and sending the paging message on each determined subframe position through repeated physical downlink shared channels (PDSCH). The present invention can solve a repeated paging message transmission problem of coverage enhancement and can also simplify a system scheduling problem.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging message transmission method and device. Background technique [0002] 1) M2M [0003] Machine-to-machine (M2M, Machine-to-machine) communication is a new type of communication concept, its purpose is to combine many different types of communication technologies, such as: machine-to-machine communication, machine control communication, human-computer interaction Mobile Internet communication, thus promoting the development of social production and lifestyle. It is estimated that the business of human-to-human communication may only account for 1 / 3 of the entire terminal market in the future, and a larger amount of communication is the communication business between machines (small bandwidth systems). [0004] The current mobile communication network is designed for communication between people, such as the determination of network capacity and so ...

AI Technical Summary

Problems solved by technology

However, using the existing paging message transmission mechanism, in each paging cycle, the UE only monitors the paging information at a corresponding subframe position, and there is no repeated transmission mechanism for paging messages, so it is impossible for terminals that need coverage enhancement Paging messages transmitted based on existing mechanisms are correctly received
