Problems solved by technology

The out-of-synchronization of resources between these base stations and terminals will cause waste of system resources, and even cause the services of multiple terminals to interfere with each other and fail to transmit. The characteristics of semi-static resource allocation also make it a waste of resources or between users. Mutual interference can last for a long time

Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] In the LTE public network, the PCFICH channel is an indication of the number of OFDM symbols occupied by the PDCCH grant channel, with a total of 2 bits. Since the LTE public network is a broadband system, there is only one PCFICH channel under one base station. For a discrete narrowband system, due to the limited receiving and transmitting bandwidth of the terminal, the authorization and transmission of each discrete resource are limited to a single discrete resource, so each discrete resource has an independent set of control channels and traffic channels, that is, each discrete A resource may have a separate PCFICH channel used to indicate information about the ...

Abstract

The invention relates to the technical field of wireless communication, and discloses a half-static resource synchronization method, a base station and a terminal of a discrete narrow-band system. The method comprises the following steps: physical control format indicator channel PCFICH indication information corresponding to a current frequency resource is set to information used for indicating the use state of the current frequency resource; the PCFICH indication information is updated according to the use state of the current frequency resource; and the updated PCFICH indication information is sent to a current terminal in real time, and if the use state of the current frequency resource is not synchronized with the state of the base station resource, the terminal adjusts the use state of the frequency resource according to the PCFICH indication information to keep resource synchronization. According to the invention, a terminal can quickly identify whether there is resource non-synchronization between a base station and the terminal or resource collision between the terminal and other terminals, and corresponding measures can be taken as soon as possible to recover resource synchronization between the base station and the terminal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for synchronizing semi-static resources of a discrete narrowband system, a base station and a terminal. Background technique [0002] The design of discrete narrowband systems in wireless communications is limited by the available frequency bands. Unlike systems that allocate continuous and wide-ranging bandwidth, various types of large-bandwidth control channels and traffic channels can be designed more easily. Because it is a discrete narrowband system, considering the power-saving characteristics of the terminal and the bandwidth capability of the RF filter, and considering the cost of the terminal in the actual product, there are a large number of terminals that only support the monitoring of control channels within a narrowband range, especially authorized channels. and reception, and one scheduling of a single terminal only supports service transmiss...
