Method of operating a media access controller having pseudo-static guaranteed time slots
First Claim
1. A method of controlling a transmitter and a receiver to adjust transmitting and receiving times in superframes having a plurality of active time slots and one or more unused time intervals, the transmitter and the receiver both being initially assigned to a starting time slot chosen from the plurality of active time slots, comprising:
- sending instructions from a controller to both the transmitter and the receiver during a first superframe, the instructions instructing the transmitter to transmit signals during an ending time slot formed in the one or more unused time intervals;
receiving the instructions at the receiver during the first superframe; and
listening for the signals at the receiver during both the starting active time slot and the ending active time slot during n consecutive superframes after the first superframe, wherein n is an integer greater than zero.

Abstract
A transmitter and a receiver are both initially assigned a starting time slot from a plurality of active time slots in a superframe structure. A controller sends instructions to the transmitter and receiver during a first superframe. These instruct the transmitter to transmit signals during an ending time slot in one or more unused time intervals in the superframes. If the transmitter receives these instructions, it immediately begins transmitting in the ending time slot. If the receiver receives the instructions, it listens for the signals during both the starting active time slot and the ending active time slot for a set number of consecutive superframes after the first superframe. If the receiver does not receive the instructions, it listens for the signals during the entire superframe until it hears instructions in a new superframe. If the transmitter misses more than the set number of superframes, it stops transmitting.

15. A method of controlling a receiver in a wireless network using superframes having a plurality of active time slots and one or more unused time intervals, the receiver being initially assigned to a starting time slot chosen from the plurality of active time slots, comprising:
-
receiving instructions from a controller at the receiver in a first superframe, the instructions instructing the receiver to receive signals during an ending time slot formed in the one or more unused time intervals; and

18. A method of controlling a transmitter in a wireless network using superframes having a plurality of active time slots and one or more unused time intervals, the transmitter being initially assigned to a starting time slot chosen from the plurality of active time slots, comprising:
-
determining whether the transmitter received instructions from a controller in a first superframe, the instructions instructing the transmitter to transmit signals during an ending time slot;
transmitting the signals during the ending time slot if the transmitter did receive the instructions in the first superframe; and
transmitting the signals during the starting time slot if the transmitter did not receive the instructions in the first superframe, and if the transmitter has not missed receiving previous instructions in m consecutive immediately previous superframes, wherein m is an integer greater than or equal to zero. - View Dependent Claims (19, 20, 21, 22, 23)
