    摘要: A method and apparatus for determining the content in bursts to be transmitted from a base station in a mobile network on a broadcast frequency in specific timeslots of a broadcast frequency frame structure. A current state of the logical channel allocated to the forthcoming burst is checked, and the content in the forthcoming burst is determined depending on the current channel state. A dummy burst with a base station specific training sequence is transmitted if there is no data to transmit, and if the dummy burst cannot be confused with a regular traffic burst according to the current channel state. The dummy burst contains no intelligible information to mobile terminals.

    摘要: A method (600) for use in a wireless communications system (100) in which there is at least a first node (110) which controls the traffic to and from user terminals (130, 140) in a cell (120) within the system, so that there is downlink traffic in the system. The first node (110) transmits downlink traffic in radio frames, each of which comprises sub-frames. The first node (110) performs measurements on pre-defined system indicators in at least said first cell (120), and based on the results of said measurements, the first node is allowed to autonomously decide (615) to vary the number of available down link sub-frames used for down link traffic in said down link radio frames and also to vary (620) the content of the down link sub frames which are used, said decision being valid (625) for a time which is specified by the first node (110).

    摘要: The present invention relates to radio communication in a cellular network and in particular to the sharing of a frequency spectrum with another network. The object is to enable robust communication in the shared band. The solution is to allocate a third band for communication in a cell. A L1/L2 control channel may be transmitted in the third band only, whereas data can be transmitted in the shared band. The L1/L2 control channel support the data communication in the shared band. The invention relates to a method and a radio base station.

    摘要: The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

    摘要: Inter-layer inter-symbol interference is avoided using diagonally layered, Multi-antenna transmissions. Known symbols are inserted at the borders between different layers to avoid inter-layer inter-symbol interference. Multiple data-streams (layers). are transmitted over multiple antennas in an effective and smart way so that inter-layer inter-symbol interference between different data-streams is avoided when changing transmit antenna for the data-streams.
