ethods and apparatus for reducing conflicts in radio communication networks // 2598035
FIELD: communication.SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. For this purpose, logic module is designed to reduce conflicts between transmissions of radio transmitters and radio receivers operating in different bands.
