Problems solved by technology

If the same synchronization information block transmission mechanism is adopted according to related technologies to meet the coverage of all user equipment, the transmission power of the scanning beam must be increased, resulting in an increase in the transmission power consumption of the base station and a decrease in the overall efficiency of the wireless system, affecting 5G User Experience of Network Devices

Abstract

This invention provides a method and a device for sending and acquiring synchronization information block. The method for sending the synchronization information block comprises the steps that a synchronization information block is sent to the user equipment within a first preset region through a first beam in the beam scanning mode, the synchronization information block comprises a main auxiliary synchronization signal, and necessary system information; the synchronization information block is sent to the target user equipment within a second preset region outside the first preset region through a second beam in the beam scanning mode; wherein the transmitted power of the second beam is greater than the transmitted power of the first beam; the interval of the second beam scanning cycle is greater than the interval of the first beam scanning cycle. Through the adoption of the method for sending the synchronization information block, under the condition that less time resources are taken up, the performance of the terminal coverage of a system can be improved, and the system power consumption and wireless resources are saved.

Description

technical field [0001] The present disclosure relates to the technical field of computer communication, in particular to a method and device for sending and acquiring synchronization information blocks. Background technique [0002] 5G or NR (New Radio) network related standardization is being carried out in 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project). One of the key technologies of the 5G network communication system is: beamforming (beamforming) technology. When broadcasting downlink synchronization signals and necessary system information, the 5G high-frequency system adopts the method of beam scanning, and quickly scans the covered cells through concentrated power. [0003] Because the 5G network communication system needs to serve both ultra-low-latency users and machine IoT users who are extremely insensitive to delay, in some application scenarios, if the area far away from the base station is only distributed, the delay is not sensi...
