METHODS AND APPARATUS FOR PHYSICAL DOWNLINK SHARED CHANNEL (PDSCH) POWER SETTING Russian patent published in 2012 - IPC H04W52/04 

FIELD: information technology.

SUBSTANCE: plurality of methods for calculating traffic-to-pilot ratios (T2P) are established in a communication system. In addition, a mapping scheme between a plurality of overhead signals and a plurality of reference signal (RS) overhead ratios, η_RS, and the plurality of T2P calculation methods is established. A user-specific T2P ratio P_B,k/P_Rs for certain OFDM symbols, a RS overhead ratio η_RS and a calculation method selected from the plurality of T2P calculation methods are assigned to a wireless terminal. Then, an overhead signal corresponding to both of the assigned RS overhead ratio η_RS and the assigned T2P calculation method is selected in accordance with the mapping scheme and is transmitted to the wireless terminal.

EFFECT: invention discloses methods and apparatus for transmitting power setting information in a PDSCH in a communication system.
