摘要： A method and network node (400) for supporting evaluation of usage of a radio network feature in radio communication between wireless devices (402) and the network node. The network node (400) retrieves (4:1) statistical information regarding the usage of the radio network feature, and reports (4:5) the statistical information to an Operation and Maintenance, O&M, node (404). The O&M node then uses (4:6) the statistical information for evaluating how measured performance (4:3) of the radio network is related to the usage of the radio network feature.

摘要： 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.

摘要： The present invention relates to methods and arrangements in a radio base station and in a user equipment for controlling the uplink transmit power 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 radio base station defines at least one TPC command for adjustment of the transmit power of the N uplink carriers (203), the number of TPC commands being equal to or lower than N1 and transmits the TPC command(s) on at least one of the M downlink carriers (201, 202, 205, 206). The user equipment receives the TPC command(s) on the M downlink carriers from at least one radio base station, and adjusts the transmit power of the N uplink carriers based on the received TPC command(s).

摘要： A method and network node (400) for supporting evaluation of performance of a radio network. The network node employs carrier aggregation with multiple carriers used in corresponding multiple cells (Cell 1, Cell2, Cell 3). The network node retrieves (4:1) statistical information regarding utilization of radio resources, wherein the statistical information indicates secondary cell use of radio resources in a particular cell. The network node reports (4:5) the statistical information to an Operation and Maintenance, O&M, node (404), thereby enabling the O&M node to use the statistical information for evaluating (4:6) how a measured performance of the radio network is related to secondary cell usage.

摘要： 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 (15) 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.

摘要： 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.

摘要： The present disclosure concerns movements, such as handovers, of user equipments (UEs) 120a-e from one radio cell 130a to another radio cell 130b. Disclosed herein are methods as well radio network nodes 110a, 110b. A radio network node 110a, 110b may, for example, select the most suitable UE(s) 20a-e to move from a source radio cell 130a to a target radio cell 130b in case the traffic load in the source radio cell 130a is below or equal to the traffic load of the target radio cell 130b. Hereby it is made possible to improve the resource utilization.
