Embodiment Construction

[0087] Embodiments of the present invention provide a method and device for timing maintenance under a coverage enhancement mechanism. Before describing the embodiments of the present invention in detail, the application fields and some technical features of the embodiments of the present invention will be described.

[0088] The embodiment of the present invention is applicable to a terminal (such as an MTC terminal) that has enabled the coverage enhancement function, and is also applicable to a network side device (such as eNB, NB, etc.) that supports the coverage enhancement function. Of course, it is also applicable to other physical or logical entities that need to maintain timing related to physical layer channels.

[0089] In the embodiment of the present invention, the timing-related physical layer channel means that the start time and effective time of the timing are related to the transmission of the physical layer channel.

[0090] In the embodiment of the present ...

Abstract

Disclosed in the present application are a method and apparatus for timing maintenance under a coverage enhancement mechanism. The method comprises: determining a time domain position for the last repeated transmission of a timing-related physical layer channel; and determining the start time of the timing according to the determined time domain position. According to the embodiment provided in the present application, the start time of the timing is determined according to the time domain position for the last repeated transmission of the timing-related physical layer channel. The invention avoids performing maintenance of said timing in a way as prescribed by the existing standards, and thereby solves the problem of how to perform physical layer channel-related timing maintenance under a coverage enhancement mechanism.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a timing maintenance method and device under a coverage enhancement mechanism. Background technique [0002] Machine to Machine (M2M) communication is a trend in the development of intelligent communication in the future. In the third generation mobile communication system and its Long Term Evolution (Long Term Evolution, LTE) system, it is necessary to support a Machine Type Communications (Machine Type Communications, MTC) function. An MTC device (MTC terminal) may have some characteristics of various M2M communication characteristics, such as low mobility, small amount of transmitted data, insensitive to communication delay, and requiring extremely low power consumption. In the existing M2M network based on the General System for Mobile Communications (GSM) technology, operators find that MTC terminals working in some scenarios, such as MTC terminals working in...
