Abstract
A wireless communication network includes numerous mobile terminals and numerous transceivers (“base stations”). In this wireless communication network, messages sent from the base stations to the mobile terminals are transmitted at a higher data rate than the messages sent from the mobile terminals to the base stations. In one embodiment, a “half-duplex” protocol assigns separate times slots for base stations and mobile terminal transmissions. In another embodiment, a modified “full-duplex” protocol provides “half-duplex” operation in the mobile terminals and “full-duplex”operation in the base stations.
