Abstract:
1. A method, in a baseband unit that is associated with a set of cells configured by a radio network controller (RNC) for simultaneous multipoint transmission of possibly different data to the same User Equipment (UE), comprising: receiving signaling identifying the configured set of cells from the RNC, wherein said baseband unit comprises one or more entities that perform scheduling for the configured set of cells; determining a subset of cells from said configured set of cells that are to be used for actual data transmission to the UE, based on considering a set of information that is not known to the RNC, wherein determining the subset of cells comprises making dynamic decisions based on at least one of the following items of information in said information set for one or more of the cells in the configured set of cells: loading, variation in the loading over time, maximum available transmit power, and loading on different carriers; dynamically transmitting or controlling the transmission of data to the UE from the subset of cells; receiving signaling from the RNC updating the configured set of cells and correspondingly determining whether and in what manner to revise the subset of cells that are to be used for actual data transmission to the UE; and signaling to the UE, via a radio node serving the UE, to deactivate sending of reports from the UE to the RNC regarding addition/deletion of new cells in the configured set of cells, if the cells are characterized by high load conditions or if the RNC is experiencing congestion.
