A method of reducing interference to reception of streams of television content received at a television receiver in which each of the streams of television content are transmitted on one of a plurality of frequency channels in accordance with a channel map which defines on which of the plurality of frequency channels each stream of television content is transmitted and the interference being caused by a base station transmitting data to or receiving data from one or more mobile devices via radio communication signals in a vicinity of the television receiver. The method includes identifying the channel map and adapting a transmission of the radio communication signals between the base station and the one or more of mobile devices in accordance with the identified channel map to reduce interference at the television receiver.

A method is disclosed of a network node of a cellular communication system for configuring a first cell of the cellular communication system in relation to a second cell of the cellular communication system. A coverage area of the first cell and a coverage area of the second cell overlap, at least partly. The first cell is to be provided by a first base station of the cellular communication system and has a first bandwidth and the second cell is provided by a second base station of the cellular communication system and has a second bandwidth which is larger than the first bandwidth. The method comprises determining an offset between a first carrier frequency of the first cell and a second carrier frequency of the second cell and configuring the first base station to provide the first cell based on the first carrier frequency. A first spectrum range defined by the first carrier frequency and the first bandwidth is comprised within a second spectrum range defined by the second carrier frequency and the second bandwidth. The offset is determined such that control signaling of the second cell is aligned with control signaling of the first cell to reduce an impact of interference between the control signaling of the first cell and the control signaling of the second cell. Corresponding computer program product, arrangement and network node are also disclosed.

A communication management resource such as a domain proxy receives a request transmitted from a wireless base station. The wireless station generates the request to register the wireless base station for subsequent allocation of wireless channels. In response to receiving the request, the communication management resource maps an identity of the wireless base station to a geographical location in which the wireless base station resides and forwards the request and notification of the geographical location to a channel allocation resource (a.k.a., allocation management resource) that allocates use of the wireless channels in a region in which the geographical location resides.

Systems and methods to reduce control data traffic between a hub radio device (e.g., a master white space device) and spoke radio devices (e.g., slave white space devices). Reduced are the number of control messages and/or the amount of data transmitted in control data messages. The hub radio device stores data regarding the spoke radio devices that register for white space access (e.g., specific spectrum access credentials) with a spectrum management server via the hub radio device. As long as conditions regarding a spoke radio device remain relatively unchanged, the stored data for the spoke radio device may be used to maintain the white space access through periodic renewal of the corresponding channel authorization with the spectrum management server.
