Abstract: The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

Abstract: 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).

Abstract: In a cellular radio system, the number of TDM users per cell is limited. The cellular radio system can be a WCDMA system and in particular a WCDMA system employing an Enhanced Uplink (EUL). Other users in the cell are scheduled using CDM scheduling.

Abstract: 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.

Abstract: 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.
