摘要:
The invention relates to an apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: convey a set of changeable sharing profiles to a node being a secondary user of the shared spectrum, the set of changeable sharing profiles including changeable spectrum sharing conditions; change at least one sharing profile of the set of changeable sharing profiles during shared spectrum usage, and indicate the change of the at least one sharing profile to the node being the secondary user of the shared spectrum.
摘要:
A method for controlling radio resource usage in a communications system is described. The method includes defining in a network apparatus, a muting pattern regarding uplink signals that are to be temporarily muted, wherein said uplink signals include higher layer configured uplink signals that are outside the control of a dynamic scheduler of the network apparatus. The defined muting pattern or a part of it is signalled from the network apparatus to one or more user equipment in order to control the user equipment to mute the respective uplink signals according to the signalled muting pattern.

The invention relates to apparatuses, a method, computer program and computer-readable medium for resource allocation (selection of channel and maximum allowed transmission power) in a coexisting secondary communications system, overlapping with a primary system. Allocation is performed based on an interference table indicating measured interference per cell of the primary system from other cells of the primary and secondary system.

Apparatus and method for communication are provided. The apparatus includes a controller for controlling the transmission and reception of data on one or more carriers utilizing Time Division Duplexing and frames including sub frames, where multiple carriers utilized by different apparatuses are synchronized with each other and a predetermined number of sub frames of each frame are reserved for predetermined transmission directions and a scheduler for allocating the rest of the sub frames carrier specifically either in downlink or uplink direction.

Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.
