METHODS AND NETWORK NODES FOR USE IN A COMMUNICATION NETWORK EMPLOYING FLEXIBLE SUBFRAMES

摘要

According to an aspect, there is provided a method of operating a network node in a communication network. The method comprises determining (121) a preferred configuration for one or more flexible subframes in a frame, the frame comprising one or more subframes allocated to uplink transmissions, one or more subframes allocated to downlink transmissions and one or more flexible subframes that can each be dynamically allocated to either uplink transmissions or downlink transmissions; and transmitting (125) a message to a neighbouring network node in the communication network through an inter node interface, the message indicating the preferred configuration for the one or more flexible subframes.
