First Claim
Patent Images
1. A method of controlling a link margin between devices for supporting communication in at least one frequency band, the method comprising:
- receiving, from a second device, a link margin information comprising information about a link margin related to a communication link between a first device and the second device; and
performing, based on the received link margin information, at least one operation selected from among a plurality of selectable operations for controlling a link margin, the plurality of selectable operations comprising a change in transmission power, a change in a modulation and coding scheme (MCS), and a change of the communication link to another frequency band.
