Cooperation Strategies for Two Co-located receivers, with no CSI at the transmitter
— We study the case of a single transmitter, which communicates to two co-located users, through an independent block Rayleigh fading channel. The co-location nature of the users allows cooperation, which increases the overall achievable rate, from the transmitter to both users. The transmitter is ignorant of the fading coefficients, while receivers have access to perfect channel state information (CSI). This gives rise to the broadcast approach used by the transmitter. The broadcast approach facilitates reliable transmission rates adapted to the actual channel conditions, designed to maximize average throughput. With the broadcast approach, users can decode partly the total message, with almost any fading realization. The better the channel quality, the more layers that can be decoded. Such an approach is useful when considering average rates, rather than outage vs. rate (outage never occurs). The cooperation between the users is performed over the co-location channel, modeled as s...
