Multi-channel time-division multiplexing access methods and systems

A wireless communication system, comprising:

• a transmitter;
• a first receiver coupled to the transmitter over a wireless medium comprising a plurality of logical channels, wherein each of the plurality of logical channels corresponds to a distinct transmission resource, wherein the wireless medium is characterized by a maximum propagation delay, and wherein a distance between the transmitter and the first receiver corresponds to a first propagation delay that is less than the maximum propagation delay;
• and
• a second receiver coupled to the transmitter over the wireless medium, wherein a distance between the transmitter and the second receiver corresponds to a second propagation delay that is less than the first propagation delay,
• wherein the transmitter is configured to:
• perform, in a first time interval of a time-division multiple access (TDMA) slot, a transmission of a first data unit over a first logical channel of the plurality of logical channels to the first receiver and the second receiver,
• refrain from transmitting, subsequent to a completion of the transmission of the first data unit, for a second time interval immediately after the first time interval, and
• perform (N−1) transmissions in (N−1) time intervals for each data unit of (N−1) subsequent data units in the TDMA slot, such that a transmission of an nth data unit of the (N−1) subsequent data units is performed over an nth logical channel of the plurality of logical channels,
• wherein the second receiver is configured to receive and decode, within the TDMA slot, at least one of N subsequent data units, wherein the first receiver is unable to receive and decode each of the N subsequent data units, wherein a duration of the TDMA slot is greater than the first propagation delay, wherein n and N are positive integers and 2≤n≤N, and wherein the second time interval is greater than or equal to a sum of a time required to perform a switching operation between two of the plurality of logical channel, a maximum delay spread of the first logical channel, and a processing latency of the first data unit.
