Abstract
A method comprises listening (151) for transmission of a preamble by a transmitting device to a recipient and receiving (153) data in a second time interval upon receiving the preamble in a first time interval. The second time interval succeeds the first time interval. The method further comprises listening (155) for transmission by the recipient of a message, e.g. a NACK, indicating that data transmitted in the second time interval was not successfully received by the recipient and retransmitting (157) the data in a fourth time interval upon receiving the message in a third time interval.
Claims13
A system for receiving a preamble, data and a message, comprising:
- at least one receiver;
- at least one transmitter;
- and
- at least one processor configured to:
- use said at least one receiver to listen for transmission of a preamble by a transmitting device to a recipient,
- use said at least one receiver to receive data in a second time interval upon receiving said preamble in a first time interval, said second time interval succeeding said first time interval,
- use said at least one receiver to listen for transmission by said recipient of a message indicating that data transmitted in said second time interval was not successfully received by said recipient, and
- use said at least one transmitter to retransmit said data in a fourth time interval upon receiving said message in a third time interval.
A device for transmitting a preamble and data,
- at least one transmitter;
- and
- at least one processor configured to:
- use said at least one transmitter to transmit a preamble in a first time interval, said preamble indicating that data transmitted in a second time interval succeeding said first time interval requires reliable reception by a recipient of said data, and
- use said at least one transmitter to transmit data in said second time interval.
A method of receiving a preamble, data and a message, comprising:
- listening for transmission of a preamble by a transmitting device to a recipient;
- receiving data in a second time interval upon receiving said preamble in a first time interval, said second time interval succeeding said first time interval;
- listening for transmission by said recipient of a message indicating that data transmitted in said second time interval was not successfully received by said recipient;
- and
- retransmitting said data in a fourth time interval upon receiving said message in a third time interval.
A method of transmitting a preamble and data, comprising:
- transmitting a preamble in a first time interval, said preamble indicating that data transmitted in a second time interval succeeding said first time interval requires reliable reception by a recipient of said data;
- and
- transmitting data in said second time interval.
