Abstract:
1. A method performed in a wireless network by a device that is communicatively coupled to another device, and where channel reciprocity exists, the method comprising: receiving signals within a downlink frequency domain to enable channel estimation; measuring two or more of the signals only for two or more frequency bands of the downlink frequency domain that correspond to two or more uplink frequency bands associated with a scheduling grant for the device or two or more uplink frequency bands associated with a channel allocation that correspond to physical uplink control channel or physical uplink shared channel frequency bands; estimating path losses based on the measured two or more signals by calculating path loss values for each of the frequency bands; calculating a total power based on the path loss values corresponding to the frequency bands; determining a power allocation per frequency band based on the calculated total power to be applied to an uplink transmission; and allocating the total power according to one of:
