|+||Limited feedback systems have been increasingly used in 3G wireless standardization efforts and beyond to facilitate opportunistic communications that take advantage of favorable channel fading conditions. Initial efforts in this direction adopt the point-to-point paradigm where each user decides the best signalling direction from an apriori designed codebook of signalling direction(s) to optimize its own chosen metric. Such a selfish design is often not optimal from a network perspective. In this talk, we will revisit the limited feedback design problem from a network viewpoint and show that significant benefits can be realized by a codebook design and codeword selection that is altruistic rather than selfish. |
