- Abstract
- We consider a case where K closely located users communicate with a base station in the uplink of a wireless communication system. Each user has a certain number of assigned time-frequency slots at its disposal. At a small cost, which we in this paper consider as negliable, the users can communicate with each other and share their data. Thus, they can cooperate in the uplink in order to save transmit power. When many single-antenna users cooperate tightly to enhance their communication using maximum-ratio transmission, they essentially form a massive MIMO array. We investigate the case with a single receiving base station antenna, but the same general principle applies with multiple receiving antennas. We formulate a game theoretic model... (More)

We investigate the case with a single receiving base station antenna, but the same general principle applies with multiple receiving antennas. We formulate a game theoretic model for this, and study what savings are possible, and to what extent users are willing to take part in the cooperation. Our findings are that large gains are possible, and that all users cooperate. Further, users are able to establish their transmit powers without any moderator. (Less)
