Abstract
A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.
Claims24
A method of identifying a time for transmitting user data on a forward link from a base station to a subscriber station, wherein the base station transmits and receives signals through a base station signal beam having a beam angle that changes over time, the method comprising:
- storing the user data in a transmit buffer;
- predicting an optimal transmit time for efficiently transmitting forward-link supplemental channel traffic to the subscriber station based on the beam angle;
- and
- transmitting the user data at the predicted optimal transmit time.
An apparatus comprising:
- a buffer configured to store user data and to provide the user data to a channel element module based on a data release signal;
- and
- a control processor configured to predict an optimal transmit time for efficiently transmitting forward-link traffic from a base station to a subscriber station, wherein the base station transmits and receives signals through a base station signal beam having a beam angle that changes over time, wherein the control processor is configured to predict the optimal transmit time based on the beam angle.
A method of identifying a time for transmitting user data on a reverse link from a subscriber station to a base station, wherein the base station sends and receives signals through a base station beam having a beam angle that changes over time, the method comprising:
- storing the user data in a transmit buffer;
- determining an efficiency of sending the user data immediately on the reverse link;
- and
- identifying the time to transmit the user data based on the efficiency.
An apparatus comprising:
- a transmit data buffer configured to store user data and to provide the user data to a channel element module based on a data release signal;
- and
- a control processor configured to predict an optimal transmit time for efficiently transmitting reverse-link traffic from a subscriber station to a base station, wherein the base station transmits and receives signals through a base station signal beam having a beam angle that changes over time, wherein the control processor is configured to predict the optimal transmit time based on the beam angle.
