Abstract

We present a simple design of a packet relay protocol that can be used for the reverse channel data traffic in CDMA TDD cellular systems. We name it synchronous Location Dependent Packet Relay (synchronous-LDPR) protocol. Mobile users in this scheme can relay its data packets via several mobile stations to the base station. By doing so, the total required power to deliver a data packet can be reduced, and the system capacity can be increased due to the reduction of the other cell interference. The synchronous-LDPR scheme utilizes a mobile´s uplink time slot not in use for transmitting its own traffic. This scheme can be superimposed on the current CDMA TDD systems.
