Title:
METHOD FOR USER EQUIPMENT TO SEND SIGNAL, AND USER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2017/015785
Kind Code:
A1
Abstract:
The present invention provides a method for a user equipment to send a signal, and a user equipment, the method comprising: in an acquired channel detection period, detecting a first interference strength in a system bandwidth and a second interference strength of each sub-band of the system bandwidth, comparing the first interference strength with a first interference threshold value, and if the first interference strength is less than the first interference threshold value, then according to the second interference strengths affecting each sub-band in the system bandwidth, selecting N first sub-bands having small interferences from the system bandwidth, and sending a signal on the N first sub-bands. By taking into account the entire bandwidth interference and the interference of each sub-band, transmission collisions are avoided when the entire system interference is small, and by selecting a sub-band with a small interference and performing signal transmission therewith, the invention further decreases transmission interference, thereby effectively improving data transmission reliability.
