Abstract
According to an embodiment of the invention, a method of operating a control node for communication with at least one receiving node is provided. The communication is structured in frames comprising several subframes (1) which may be divided into subbands in the frequency domain. The method comprises transmitting a control channel in a search area (8) of one of the subframes (1). The search area (8) comprises a configurable time span and may span one or more of the subbands.

A method of operating a control node for communication with at feast one user equipment, the communication being structured in frames comprising several subframes, the method comprising:
- transmitting a control channel in a search area in only a subset of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
A method of operating a user equipment for communication with at least one control node, the communication being structured in frames comprising several subframes, the method comprising:
- searching for a control channel in a search area in only a subset of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
A control node configured to communicate with at least one user equipment with the communication being structured in frames comprising several subframes, the control node configured to:
- transmit a control channel in a search area in only a subset of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
A user equipment configured to communicate with at least one control node, the communication being structured in frames comprising several subframes, the user equipment configured to:
- search for a control channel in a search area in only a subset of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
A control node, comprising;
- a transmitter for communication with at least one receiving node, the communication being structured in frames comprising several subframes and
- a controller configured to control the transmitter to transmit a control channel in a search area in only a subset of one of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
A user equipment, comprising:
- a receiver for communication with a control node, the communication being structured in frames comprising several subframes;
- and
- a controller configured to search for a control channel in a search area in only a subset of the subframes, the search area comprising a configurable time span and the subset of the subframes in which the control channel is transmitted being indicated by a bit map.
