The invention relates to a scheduling of data transmissions in multi-carrier data transmission systems, e.g. multi-carrier W-CDMA systems. A method embodiment of performing one or more data transmissions in a multi-carrier data transmission network (100) comprises, in a transmitting device (102), the steps of requesting transmission resources from a resource granting device (106); receiving, in response to the request (120), one or more transmission grants (gr1-gr3) from the resource granting device (106), wherein each transmission grant (gr1) indicates a data rate (dr1) and a data class (CI1) granted for a specific transmission carrier (Cr1); and initiating one or more transmissions (122-126) of data associated with one or more of the granted data classes on one or more of the granted transmission carriers.

The present invention relates to a method for allocating communication bandwidth between a first terminal of a plurality of terminals and a network device. Wireless communication between the first plurality of terminals and the network device is carried out using a plurality of carrier channels. The communication defines a first bandwidth. The method comprises the steps of receiving the request for change of bandwidth from the first terminal, evaluating current load on carrier channels in use by the first terminal, evaluating priority between all terminals using the carrier channels currently in use by the first terminal, evaluating capacity of all carrier channels available to the first terminal, and allocating a second bandwidth between the network device and the first terminal by allocating a new number of carrier channels. The present invention further relates to a network device and a device for communication.

The invention relates to a method for reducing interference between users in a mobile communications network (1) in which uplink transmissions from user equipment, UE (3), to a radio base station, RBS (5A, 5B), can be performed on at least two different carriers (C1, C2). The UE (3) support dynamic switching between CDM and TDM transmission mode and the RBS (5A, 5B) is arranged to dynamically set the mode of transmission for the UE (3). The method comprises the steps of: —identifying (S200) at least a first UE as a high data rate, HDR, UE currently requiring high data transmission rate; dedicating (S201) at least one of said at least two carriers (C1, C2) to said HDR UE for at least a first period of time (T), said at least one carrier (C1, C2) hereinafter being named clean carrier, and—allocating (S202) said at least first HDR UE to said clean carrier (C1, C2) during said at least first period of time (T). This method ensures that no UE operating in CDM mode is transmitting on the same carrier at the same time as the HDR UE.

The present invent ion relates to a mobile advertisement system (100), a method and an application server (40) used to prevent user equipments (10) hosting a forged client 5 application or client software to get access and to hold an external data network connection. According to the present invention, an application server (40) is adapted to receive from the core network (20) of the advertisement system (100) a message comprising an end user identification number (e.g. MSISDN). The application server is further configured to trigger an advertisement confirmation timer which expects to receive an advertisement display confirmation message from the client of the user equipment (10). Upon the timer expiring, the application server (40) request the core network (20) to disconnect the user equipment thereby preventing the user equipment hosting a forged client application to get access and to hold a external data network connection.

A radio base station (1) for use in a wireless communication system comprises—a scheduling unit (9) arranged to schedule at least one user terminal to which to transmit in each subframe and—a power allocation unit (11) arranged to allocate a first amount of power to be used for the at least one user terminal in each subframe, a transmitter (5) arranged to transmit a transport block in a subframe to a number of user terminals (3) in the wireless communication system in accordance with said scheduling and power allocation. The radio base station further comprises—a correction unit (5) arranged to determine, after scheduling has been performed for a chosen subframe, if there is excess power in the chosen subframe that has not been allocated to any user terminal and if so allocate at least a first part of the excess power to at least one user terminal scheduled in the subframe. The excess power is used when transmitting in the subframe.

The present invention relates to methods and arrangements in a radio base station and in a user equipment for controlling the downlink transmit power of the F-DPCH in a multi-carrier HSPA system, by using the concept of TPC commands (used in single-carrier systems), adapted to support different kinds of multi-carrier scenarios. The UE defines at least one TPC command for adjustment of the transmit power of the N downlink carriers' (203) F-DPCH, the number of TPC commands being equal to or lower than N, and transmits the TPC command(s) on at least one of the M uplink carriers (201, 202). The radio base station receives the TPC command(s) on the M uplink carriers from the user equipment, and adjusts the transmit power of the N downlink carriers' F-DPCH based on 10 the received TPC command(s).
