Primarily used in military communications in the past, code division multiple access (CDMA) has become attractive for personal communications. As a large number of mobile hosts are supported and a wide range of services are provided, one important issues in a CDMA personal communication network is the control of the uplink access to the wireless spectrum. In this paper, we address it in a realistic situation where the receiver-oriented transmission protocol is employed and multiple access interference (MAI) cannot be ignored. A medium access control protocol for voice and data integration is proposed. It solves the problems of code assignment and MAI control at the same time. A Markov chain model is used to analyze the protocol. Based on the modeling, the effectiveness of the protocol's MAI control is demonstrated and some system design issues are investigated.
