<p>Power control for wireless communication may involve determining the tran smit power to be used by a wireless device. A wireless device using open loo p power control may select a transmit power based on an open loop power equa tion where a parameter of the power equation may be based on one or more pow er control messages received from another wireless device. In some aspects, path loss may be estimated for open loop power control and a value for Offse t_BSperSS may be obtained from information provided by a base station for cl osed loop power control. To facilitate a stable combined open-closed loop al gorithm, open loop power control may be used to compensate channel changes b ased on reciprocity, and closed loop power control may be used to compensate interference variations (e.g., as compared to NI provided by a DCD message) .</p> |
