摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radio frequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

摘要： A multi-branch OFDM receiver combines diversity signals received over different receiver branches using interference rejection combining. The receiver generates first channel estimates associated with a serving base station, second channel estimates associated with at least one non-serving base station, and a time offset between the serving base station and non-serving base station. The receiver computes a noise covariance matrix based on the second channel estimates and the time offset, and then combines the diversity signals received over different branches using the first channel estimates and the noise covariance matrix.

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 embodiments herein relate to a method in a relay node (110) for relaying data from a first network node (107) to a second network node (101) in a radio communication network (100). The relay node (110)receives the data from the first network node (107) and decodes the received data. The relay node (110) determines a delay constraint of the decoded data and recodes the decoded data. The relay node (110) relays the recoded data to the second network node (101) based on the determined delay constraint and according to a radio communication protocol. The communication between the relay node (110), the first network node (107) and the second network node (101) is based on the same radio communication protocol.

摘要： A method for initial scanning of frequencies at start-up of a multi-band cellular communication apparatus is disclosed. The method comprises determining (100) whether there is any interfering signal from any other communication system transmitting at a frequency in vicinity of frequencies of frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands. If the determination (100) gives a result of no interfering signal (102), a first scan procedure (104) is applied comprising plain scanning of the frequencies of the frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands, or if the determination gives a result of an interfering signal (102), a second scan procedure (106) is applied, taking into account the determined interfering signal. A frequency scanning apparatus (206) for initial scanning, and a radio access circuitry for such initial scanning is also disclosed.

摘要： Methods and arrangements, for supporting cell selection in a mobile terminal (UE1, 1101) associated with a set of serving cell candidates (Cell1, Cell2, Cell5, Cell7, Cell10). The method in the mobile terminal involves evaluating (804, 806) a first serving cell candidate (Cell5) from the set by estimating (804) the distance (d 5 ) from the mobile terminal to the first serving cell candidate and determining (806) whether the estimated distance exceeds a predetermined distance, based on a criterion. The method further involves refraining (810) from performing a call on the first serving cell candidate if the estimated distance exceeds the predetermined distance and instead evaluating (812, 814) a second serving cell candidate (Cell1) from the set. The methods and arrangements enable selection (808, 816) of a serving cell, from amongst the serving cell candidates in the set, within a predefined distance from the mobile terminal.
