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： A method in a radio network node (140) for handling hand over of a user equipment (150) to a target cell. The target cells hares a physical cell identity(PCI) with at least a second cell in a cellular communications network. When the target cells hares the PCI with the at least second cell, the radio network node (140) sends (204) a message to the respective at least two cells requesting to set up a radio link to the user equipment(150) and comprising an indication to measure a characteristic of an up link synchronization and comprising an indication to send a report comprising a result of the indicated measurement to the radio network node (140). The radio network node (140) receives from the at least two cells a respective report, which respective report comprises a result of the indicated up ink measurement. The radio network node (140) selects (209) the target cell for hand over of the user equipment (150), based on the result in the report. Publ.

摘要： A method performed by a network node (110) for determining amounts of downlink transmission power for a downlink shared channel to be used in a Transmission Time Interval, TTI, by cells (201, 202) served by the network node (110) in a wireless telecommunications network (100) is provided. The network node determines downlink transmission power available to the cells (201, 202) for physical channels associated with the downlink shared channel based on the downlink transmission power allocated in the cells (201, 202) to physical channels associated with other downlink channels. Further, the network node determines an additional amount of downlink transmission power available to at least one first cell (201) based on the difference between the determined downlink transmission power available to at least one second cell (202) and a downlink transmission power that is required for the amount of data that is to be transmitted in the at least one second cell (202). A network node (110) for determining amounts of downlink transmission power for a downlink shared channel to be used in a Transmission Time Interval, TTI, by cells (201, 202) served by the network node (110) in a wireless telecommunications network (100) is also provided.
