Abstract: The invention relates to a radio base station (102) and method in a radio base station of a cellular communications system (100) for controlling self-interference. The radio base station (102) supports communication with a user equipment (101) using multiple uplink and multiple downlink carriers (104a, 104b, 105a, 105b). The method comprises detecting a degraded downlink performance on a downlink carrier (105a) due to self-interference by determining that a set of predefined conditions applies. The method further comprises executing, in response to detection of the degraded downlink performance, an action to reduce self-interference between the uplink and downlink carriers (104a, 104b, 105a, 105b). The action is one of: uplink scheduling to reduce self-interference, deactivation of a secondary uplink carrier (14a, 104b), deactivation of a secondary downlink carrier (105a, 105b), and initiation of carrier reconfiguration to reduce self-interference.

Abstract: The present invention relates to frequency hopping in wireless communication systems utilizing single-carriers with varying bandwidth. Frequency hopping is made possible by dividing the available bandwidth, associated to the available frequency spectrum, in a leveled structure, a bandwidth tree. By the use of a frequency hopping tree, which has the same structure as the bandwidth tree and wherein each leaf represent a hopping sequence, a frequency hopping scheme is determined. Orthogonality in-between the frequency hopping schemes for different users is ensured by letting a users hopping sequence value at a level n, be dependent on the hopping sequence value associated to the same branch structure on the adjacent level closer to the root of the tree, n?1, and an input sequence associated with the level n.
