Nodes and Methods Therein for Managing Time-Frequency Resources

摘要

Method in a first node for managing time-frequency resources. The first node is comprised in a wireless network. The first node serves at least one user equipment in the wireless network. The first node determines a blanking ratio of a low interference time-frequency resource pattern, and/or an amount of required protected time-frequency resources. The determining is based on one or more parameters related to the user equipment served by the first node. The determining is for recommending to a second node comprised in the wireless network, and using the low interference time-frequency resource pattern. The first node signals information to the second node. The information comprises at least one of: the determined blanking ratio, the determined required amount of protected time-frequency resources, and the one or more parameters. The at least one user equipment served by the first node receives interference from the second node.
