Time division multiplexed access method of operating a near field communication system and a near field communication system operating the same

摘要

A TDMA method of operating a near-field communication system, in which the same synchronous slot is allocated to more than one, non-interfering, transmitters, is disclosed. The power level may be adjusted to minimize interference from unwanted transmitted signals at respective receivers. A near-field communication system operating such a method is also disclosed.

1. A method of operating a near-field communication system comprising a first transmitter, a second transmitter and a binaural hearing aid system comprising a left receiver and a right receiver, according to a time division multiplexed access arrangement wherein a time division multiplexed access frame comprises at least a first synchronous channel slot, wherein a distance between each of the first transmitter and the second transmitter and an opposite receiver is greater than a distance between the left receiver and the right receiver, the method comprising:
transmitting a left signal from the first transmitter during the first synchronous channel slot, transmitting a right signal from the second transmitter during the first synchronous channel slot, receiving the left signal by the left receiver, and receiving the right signal by the right receiver, wherein the time division multiplexed access frame further comprises a random channel slot for concurrent transmission from the first and second transmitters, the method further comprising transmitting a control signal from one of the first and second transmitters during the random channel slot.
