摘要： Embodiments of the disclosure provide methods and apparatuses for scheduling radio resources in a communication system. According to the method, in response to receiving a request for accessing a target frequency band utilized by a Macro BS and a LPN from a frequency-shared system, a first notification is transmitted to the Macro BS, such that the Macro BS deactivates the target frequency band, and a second notification is transmitted to the LPN, such that the LPN extends its coverage. Then, information on the extended coverage is received from the LPN.

摘要： There is provided an interference mitigation or frequency channel collision mitigation scheme usable for a short range communication network where a network element of a cellular network is used as a coordinator or controller for the collision mitigation. Communication information regarding a communication in the short range communication network and concerning a frequency selection for a communication are processed so as to determine collision mitigation data for reducing interference in the communication in the short range communication network. The collision mitigation data regarding the communication in the short range communication network are sent to a communication network element such as a UE acting as a master node of the short range communication network.
