Abstract
A mobile terminal sends rapidly changing information relating to the downlink transmission of packet data from a base station sector to the mobile terminal at a higher rate on a fast channel. This rapidly changing information may include, for example, a current data transmission rate and/or a current base station sector identification. Information that changes more slowly, such as the identification of a base station to handle the mobile terminal communication, is communicated to the base station at a lower rate on a slow channel. The information received from the mobile terminal at the higher rate is used by the base station to request a particular sector (and preferably also a sector antenna) to transmit data to the mobile terminal and/or to adjust the current maximum data transmission rate to the mobile terminal. A mobile terminal may also make similar sector/rate requests from plural sectors at the same time as well as from plural sector antennas.
