Abstract
A method for use in a broadband wireless access protocol (such as IEEE 802.16 or Long Term Evolution (LTE)) includes scheduling by a base station a stand-by subscriber station for each subscriber station with uplink (UL) transmission opportunities, transmitting by the base station and over the network, a list of each of the stand-by subscriber stations, determining by the stand-by subscriber stations if there is unused bandwidth reserved for the corresponding subscriber station, communicating to the base station that there is the unused bandwidth, and releasing the unused bandwidth for use by the stand-by subscriber station.
Claims15
A method for use in a broadband wireless access protocol in a network to provide bandwidth recycling, the method comprising:
- scheduling by a base station a stand-by subscriber station for each subscriber station with uplink (UL) transmission opportunities;
- transmitting by the base station and over the network, a list of each of the stand-by subscriber stations;
- determining by the stand-by subscriber stations if there is unused bandwidth reserved for the corresponding subscriber station;
- communicating to the base station that there is the unused bandwidth;
- and
- releasing the unused bandwidth for use by the stand-by subscriber station.
A system for communication over a network which provides for bandwidth recycling, the system comprising:
- a base station;
- a plurality of subscriber stations;
- a plurality of complementary subscriber station;
- wherein the base station is configured for scheduling a complementary subscriber station for each of the plurality of subscriber stations and communicating a list containing the complementary subscriber stations;
- wherein each of the subscriber stations is configured for sending a stuff byte value to the base station if the subscriber station has unused bandwidth;
- wherein each of the subscriber stations is configured for sending a releasing message to a corresponding complementary subscriber station to inform the corresponding complementary subscriber station to recycle the unused bandwidth.
