Problems solved by technology

For independent deployment, the disadvantage is that the design of the high-band system is complex, the cost is high, and the coverage of the high-band is limited, which cannot support mobility well
When the user moves, due to the small coverage radius, problems such as frequent switching will occur, which will affect the system performance

Abstract

The invention discloses an information transmission method and system and related equipment which realize cooperative transmission between a high frequency band and a low frequency band and improve the system performance. The information transmission method is applied to a wireless cell covering a high frequency band and a low frequency band simultaneously, and comprises the steps that network-side equipment determines a first reference value representing the network state of terminal equipment in the wireless cell; a control information transmission state of the terminal equipment is determined according to the first reference value, wherein the control information transmission state is used for representing bearing conditions of the high frequency band and the low frequency band for control information according to the control information type; and the determined control information transmission state is sent to the terminal equipment.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to an information transmission method, related devices and systems. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) Long Term Evolution (LTE) system and its enhanced Long Term Evolution (LTE-Advanced, LTE-A) system are fourth-generation communication systems and standards, and The current mainstream standard. In the future, facing the continuous expansion of Internet and Internet of Things business needs, the 5th Generation mobile communication (5G) network has great demands on delay, coverage, transmission rate, etc., especially for office areas In dense areas such as stadiums and stadiums, more frequency bandwidth is required to meet the rate requirements of a large number of users. The existing 4th Generation mobile communication (4G) network (such as LTE or LTE-A) cannot meet the demand due to l...
