Abstract: A method in a UE for deciding whether to monitor a downlink control channel in a subframe is provided. The UE operates with discontinuous reception, DRX and dynamic time division duplex, TDD. The UE is in an active state of a DRX cycle. The UE determines (701) that the subframe is a fixed downlink subframe or that the subframe is a flexible subframe currently configured to operate as a downlink subframe. Upon determining that the subframe is a fixed downlink subframe, the UE updates (702) a first DRX timer. Upon determining that the subframe is a fixed downlink subframe or that the subframe is a flexible subframe currently configured to operate as a downlink subframe, the UE decides (704), to monitor the downlink control channel in the subframe.

Abstract: A method for performing link adaptation in association with scheduling a data channel for a cell in a base station of a cellular communication system, and an arrangement, suitable for performing such a method. The link adaptation method has link adaptation optimization purpose which is achieved by updating a link adaptation parameter on the basis of the load on the data channel and on the basis of the load of a control channel controlling the data channel in the cell. The method obtains a better trade-off between the spectral efficiency and the delay, due to re-transmissions.

Abstract: A method in a base station for selecting a set of transport format schemes for a cell is provided. The set of transport format schemes shall be used for a radio transmission from a communication device to the base station. The base station is serving the eel! comprising the communication device. The communication device is unsynchronized for transmission to the base station. The base station specifies (201) a plurality of sets of transport format schemes. Each set of transport format schemes is associated to a respective guard time, which guard time is a time margin required to compensate for the communication device being unsynchronized for transmission to the base station. After determining (203) a required guard time as the maximum timing advance value used in the cell the base station selects (204) one set of transport format schemes from the plurality of sets of transport format schemes to be available for the cell. The set is selected such that its associated guard time matches the determined required guard time in the cell.

Abstract: In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.

Abstract: A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.
