Large scale CSI required by PC algorithms.

PC scheme	Channel gain knowledge	Comment
LTE OFPC	,	OFPC is a simple one-shot suboptimal scheme that needs its own channel gain only
Utility maximizing PC	,	Iterative optimal scheme, where the Tx needs the current SINR level at the receiver
BPC	, , ,	One-shot optimal scheme: and are needed for estimating the SINR
