摘要： A method of controlling operation of a communication device arranged to operate in a cellular communication network employing a paging signal to allow discontinuous reception for communication devices is disclosed. The communication device is arranged for three main communication states: detached state where the communication device is not registered to the cellular communication network; idle state where the communication device is registered to the cellular communication network, and receives paging signals through discontinuous reception; and active state where the communication device is registered to the cellular communication network and performs communication with the cellular communication network essentially continuously. The method comprises i) connecting to the cellular communication network such that a transition from the detached state to any of idle state or active state is made; ii) performing scheduled operations in the active state or idle state; iii) determining, when a transition from the active state to the idle state occurs, time instant for next operation in the active state; iv) disconnecting from the cellular communication network such that a transition to the detached state is made; and v) when the time for next operation in the active state is approaching, returning the procedure to step i). A transceiver and a computer program are also disclosed.

摘要： The invention proposes a way of inserting an analog test signal during normal reception into analog blocks of an OFDM receiver in such a way that the reception is either not corrupted at all, or only very little. This is achieved either by inserting the analog test signal in time or frequency where it does not corrupt the received signal, or by accounting for the interfering analog test signal in the decoding process.

摘要： A method of a network node of a cellular communication system adapted to communicate with a wireless communication device is disclosed. The method comprises acquiring a signal processing capability of the wireless communication device, scheduling one or more first time-frequency resources of a first occasion of communication for transmission to the wireless communication device based on the acquired signal processing capability, and determining a length of a time interval between the first and a second occasion of communication between the network node and the wireless communication device based on the acquired signal processing capability. The method further comprises transmitting data to the wireless communication device during the first occasion using the scheduled first time-frequency resources, and performing an operation of communication between the network node and the wireless communication device during the second occasion of communication. Scheduling the one or more first time-frequency resources and determining the length of the time interval based on the acquired signal processing capability comprises, if the acquired signal processing capability does not fulfill a signal processing capability requirement, determining the length of the time interval such that a first length is selected if the scheduled one or more first time-frequency resources have a first frequency span and a second length is selected if the scheduled one or more first time-frequency resources have a second frequency span, where the first length exceeds the second length and the first frequency span exceeds the second frequency span.
