Uplink power control in a TDD communication system

摘要

A method performed in a wireless network includes receiving signals within a downlink frequency domain to enable channel estimation and measuring two or more 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 or channel allocation that correspond to physical uplink channel frequency bands. The method also includes calculating path loss values for each of the frequency bands and calculating a total power based on the path loss values corresponding to the frequency bands. The method further includes 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.
