Embodiment 1

[0045] With the development of intelligent terminals and the enrichment of wireless data application services, the number of data users in wireless communication networks has increased significantly, and wireless data content is no longer limited to traditional text or images, and more and more high-definition Video, mobile TV and other multimedia business content, resulting in explosive growth of wireless communication network traffic. Mobile Internet and Internet of Things business will become the main driving force for the development of mobile communications.

[0046] For the Internet of Things, the 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) standard organization has formulated MTC (Machine Type Communication, Machine Type Communication) and NB-IoT (NarrowBand Internet of Things, Narrowband Internet of Things) two very Representative communication standard protocol. For the mobile Internet, the 3GPP standards organization has recently ...

The information receiving device 50 may be deployed on a terminal to implement the information receiving method in the foregoing embodiments.

[0175] In this embodiment, the function of the s...

Embodiment 3

[0202] In order to make those skilled in the art more aware of the advantages and details of the aforementioned information sending method and information receiving method, this embodiment will continue to introduce the information transmission scheme with examples:

[0203] In a wireless communication system, a base station sends uplink transmission configuration information to a terminal (referred to as UE), wherein the uplink channel configuration information includes:

[0204] Configuration information of uplink channel resources;

[0205] Configuration information of the downlink control channel search space;

[0206] In this embodiment, the uplink transmission configuration information may support data transmission of the UE in the RRC-IDLE state.

[0207] The configuration information of uplink channel resources indicates the location information of a group of uplink channel resources, such as Image 6 As shown, the configuration period of the uplink channel resource ...

Abstract

The embodiment of the invention provides an information sending method and device, an information receiving method and device, a base station, a terminal and a communication system. The base station sends uplink transmission configuration information to the terminal, the uplink transmission configuration information comprises configuration information of uplink channel resources and / or configuration information of a downlink control channel search space, and information carried by a downlink control channel in the downlink control channel search space comprises downlink control information DCI. Therefore, the terminal can detect the DCI sent by the base station and realize downlink transmission with the base station. Therefore, the configuration information is indicated through uplink transmission; whether the terminal is in an RRC connection state or an RRC space state is determined. Therefore, information transmission can be smoothly and naturally realized, when the terminal is in anRRC space state, data transmission can be completed without state switching, power consumption and resource consumption caused by state switching of the terminal are reduced, optimal configuration ofterminal resources is facilitated, and user experience of a terminal side is enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information sending and receiving method, device, base station, terminal and communication system. Background technique [0002] At present, before sending or receiving data, the terminal needs to enter the RRC-CONNECT (Radio Resource Control CONNECT, radio resource control connection) state from the RRC-IDLE (Radio Resource Control IDLE, radio resource control idle) state, and then send or receive data. . However, the terminal entering the RRC connection state from the RRC idle state will consume power consumption and system resources of the terminal. Therefore, a new data transmission method needs to be provided to solve this problem. Contents of the invention [0003] The information sending and receiving method, device, base station, terminal and communication system provided by the embodiments of the present invention mainly solve the technical problem of providing a...
