Embodiment Construction

[0062] In the 5G system, broadcast-type signals and channels, such as synchronization signals and physical broadcast channels (NRPhysical Broadcast Channel, NR-PBCH), have been redesigned. However, the redesign of the system also brought a series of problems.

[0063] For example, in an LTE system, system information mainly including a Main Information Block (Main Information Block, MIB) and a System Information Block (System Information Block, SIB) are sent to user equipment (User Equipment, UE) in a broadcast manner. Due to the frequent transmission of system information, large inter-cell interference may be caused, especially in an ultra-dense network (Ultra Dense Network, UDN). Therefore, in the 5G system, system information is divided into two categories, one is Minimum System Information (MSI), and the other is Other System Information (OSI). The minimum system information is still sent to the user equipment by broadcasting, while other system information is sent to the...

Abstract

A transmission method, reception method, base station, and user equipment of a common control message, the transmission method comprising: configuring a common control channel, and transmitting scheduling information of the common control message to the user equipment on the common control channel; wherein The common control channel is carried by preset resources; the common control message is transmitted on the physical downlink data channel corresponding to the scheduling information. The transmission of public control messages can be realized by adopting the above solution.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a method for transmitting and receiving a common control message, a base station and a user equipment. Background technique [0002] In the 5G communication system, broadcast-type signals and channels, such as synchronization signals and physical broadcast channels (NRPhysical Broadcast Channel, NR-PBCH), have been redesigned. However, the redesign of the system also brought a series of problems. [0003] For example, for the redesigned 5G communication system, how to realize the transmission of public control messages has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] The problem solved by the present invention is how to transmit common control messages. [0005] In order to solve the above problem, the present invention provides a method for transmitting a common control message, the method comprising: configuring a common control...
