    摘要： A radio access network node and method of allocating cell downlink power to a set of channels (e.g., DPCH channels) and to a high-speed shared channel such as a high-speed downlink shared channel (HS-DSCH) or a high-speed shared control channel (HS_SCCH). After allocating part of the cell downlink power to the set of channels, the node allocates only a portion of the remainder of the cell downlink power to the high-speed shared channel. The node reserves a power margin for possible use during a future timeslot of a channel of the set.

    摘要： An uplink signal-to-interference ratio for each of multiple mobile radio terminal connections supported in a cell in a cellular communications system is estimated. A signal-to-interference ratio error is determined for selected ones of the estimated uplink signal-to-interference ratios. One or more signal-to-interference ratio errors are identified that exceed a signal-to-interference ratio error threshold. An instability indicator associated with the cell is determined based on the one or more identified signal-to-interference ratio errors. A load control decision and/or a decision for scheduling one or more uplink mobile radio transmissions in the cell may then be made based on the instability indicator, e.g., to prevent a transmission power rush in the uplink in the cell and/or to efficiently use available resources for uplink transmissions.

    摘要： The invention relates to a method in a radio base station (110) of a radio telecommunications network (100), wherein the radio base station (110) comprises at least two different types of receivers; a first type of receivers and a second type of receivers. The first type of receivers comprises a different receiving sensitivity than the second type of receivers. The method is for scheduling a first type of receiver to a user equipment (120) within a radio cell (115) served by the radio base station (110). The radio base station determines a distance (125) between the user equipment (120) and a radio cell boundary (127) of the radio cell (115), and schedules the first type of receiver to the user equipment (120) when the distance is determined to be within a distance range.

    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.
