    Abstract: A method and apparatus for initiating a telecommunications uplink from a mobile terminal to a telecommunications network. A preamble signal is transmitted from the mobile terminal to the network in accordance with a transmission parameter of the mobile terminal. The parameter is changed and the preamble retransmitted until successful receipt in the network is confirmed. Changing the transmission parameter alters the signal diversity of one or more preambles as received by the base station.

    Abstract: A method for allocating downlink transmission power of coordinated transmission devices in coordinated multi-point transmission system includes the coordinated transmission devices receiving feedback of channel state information of sub-channels occupied by a terminal from the terminal. The channel state information includes channel phase information and channel amplitude information. Each of the coordinated transmission devices adjusts phases of their sending signals over its sub-channels respectively so as to make phase difference of the sending signals, which are received by the terminal from the coordinated transmission devices via a same sub-channel, to be minimal. Each of the coordinated transmission devices determines its power allocation proportions for the sub-channels on the basis of feedback of channel amplitude information from the terminal and the adjusted phases of the sending signals. By adapting coordinate Iterative Water filling Power Allocation Algorithm with low complexity, the capacity of the system is increased.

    Abstract: A solution to overcome synchronization problems related to a scenario where multiple radio access networks utilize a shared frequency band in a radio communication environment is provided. The radio access networks are synchronized to a common synchronization source which may be a synchronization signal broadcasted by another radio system. The synchronization source is selected from a predetermined set of synchronization signals according to the availability of the synchronization signals for transmitters of the radio access networks.

    Abstract: A communication system that comprises a base station and a substation connected to the base station. The base station maintains a set of identifiers, each identifier of the set being at least temporarily allocatable to a user equipment for identifying the user equipment when it resides in a cell of the base station. From the set of identifiers of the base station at least one subset of identifiers is extracted, and assigned to the substation. The substation may then respond to a connection establishment request of user equipment by providing it with an identifier from the subset of identifiers assigned to it. The substation also transmits to the base station information on the connection establishment request and on the identifier provided to the user equipment.
