Large scale CSI required by RA algorithms.

RA scheme	Channel gain knowledge	Complexity	Comment
MinInterf	, , , ,		All cross-channel gains are needed to minimize the sum interference
Balanced random allocation (BRA)	, ,		and are needed for MS
Cellular protection allocation (CPA)	, ,		and are needed for MS
Matching	, , ,	where	and are needed for generating the weight matrix
