TY - CONF ID - MMK06 L3 - citeulike-article-id:2923367 N2 - A new structure for multi-base systems is studied in which each user receives data from two nearby base stations, rather than only from the strongest one. This system can be considered as a combination of broadcast and multi-access channels. By taking advantages of both perspectives, an achievable rate region for a discrete memoryless channel modeled by Pr(y₁,y₂|x₁,x₂) is derived. In this model, x₁ and x₂ represent the transmitted signals by the transmitter one and two, respectively, and y₁ and y₂ denote the received signals by the receiver one and two, respectively. In this derivation, it is assumed that each transmitter is unaware of the data of the other transmitter, and therefore x₁ and x₂ are independent. To investigate the advantage of this scheme, an efficient signaling method which works at a corner point of the achievable region for multiple-antenna scenarios is developed. In the proposed scheme, each base station only requires the state information of the channels between the other base station and each user.
