Claim Text:
1. A method for determining power for uplink transmission to a base station by a user equipment for simultaneously transmitting signals to a plurality of nodes, the method comprising: receiving uplink power control information from the base station; and determining an uplink transmit power P based on the uplink power control information, wherein the uplink power control information includes a cell-specific weight and a user equipment-specific weight applied to downlink pathloss of the plurality of nodes, and wherein the uplink transmit power P is determined based on a following Equation 1 or Equation 2: wherein, in Equation 1, A is a value determined based on one or more power control parameters provided by the base station, PL is the downlink pathloss measured by the user equipment, α is the cell-specific weight, and α′ is the user equipment-specific weight and, in Equation 2, P is a transmit power of an uplink data channel, L corresponds to downlink propagation loss including the downlink pathloss, calculated by the user equipment, α′ is the user equipment-specific weight, and B is a value determined based on one or more power control parameters provided by the base station.
