    Abstract:New demand in future wireless networks requires the capability of efficiently handling concurrent connection requests of a massive number of potential users, each with possibly low duty cycle and short message to send. Conventional multiuser information theory focuses on the regime of a fixed number of users and long messages, and thus usually falls short of characterizing the behavior of communication systems under such a “many-access” scenario. In this talk, we present our preliminary results of many-access over an OR channel, which implements an OR logic upon all the active users’ channel inputs. Our results include capacity analysis and coding schemes.
