Abstract
A method and apparatus for controlling a link margin are provided. The method includes: receiving, from a second device, a link margin frame including information about the link margin related to a communication link between a first device and the second device; and performing at least one operation selected from among a change in transmission power, a change in a modulation and coding scheme (MCS), beam forming, and a change of the communication link to another frequency band, based on the received link margin frame.
Claims20
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 frame comprising information about a link margin related to a communication link between a first device and the second device;
- and
- performing at least one operation selected from among a change in a modulation and coding scheme (MCS) and a change of the communication link to another frequency band, based on the received link margin frame.
An apparatus for controlling a link margin related to a communication link between a first device and a second device in a network comprising devices for supporting communications in at least one frequency band, the apparatus comprising:
- a receiver which receives, from the second device, a link margin frame comprising information about the link margin related to the communication link between the first device and the second device;
- and
- an operation performing unit which performs at least one operation selected from among a change in a modulation and coding scheme (MCS) and a change of the communication link to another frequency band, based on the received link margin frame.
