Abstract
Systems are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, the energy used to transmit an acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK. The energy used to transmit an ACK is set to be significantly less than the energy used to transmit a NACK. Preferably, the energy used to transmit the acknowledgement message is negligible if the acknowledgement message is an ACK compared to if the acknowledgement message is a NACK. In one embodiment, the energy used to transmit an ACK is set near zero and the energy used to transmit a NACK is set approximately four times the energy of an acknowledgement message if the energy required to transmit a NACK and an ACK were equal.
Claims23
A communication system, comprising:
- at least one terminal;
- and
- at least one network infrastructure in wireless communication with the at least one terminal;
- wherein the at least one terminal is configured to communicate with the at least one network infrastructure by sending a message to the at least one network infrastructure;
- wherein upon receiving the message from the at least one terminal, the at least one network infrastructure is configured to determine the success or failure in reception of the message and, in response, send an acknowledgement message to the at least one terminal, the acknowledgement message consisting of either an ACK indicating successful reception of the message or a NACK indicating failure of reception of the message, wherein energy used to transmit the acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK;
- and
- wherein the energy used to transmit an ACK is set near zero and the energy used to transmit a NACK is set approximately four times the energy of an acknowledgement message in a system where the energy required to transmit a NACK and an ACK are equal.
Network infrastructure suitable for use in a communication system having at least one terminal in wireless communication with the network infrastructure, the terminal being configured to send a message to the network infrastructure, the network infrastructure comprising:
- a transceiver configured to receive message from the terminal and send messages to the terminal;
- and
- a processor operably connected to the transceiver, the processor configured to control operation of the network infrastructure;
- wherein, upon receiving a message from the terminal, the processor is configured to determine the success or failure in reception of the message and, in response, instruct the transceiver to send an acknowledgement message to the terminal, the acknowledgement message consisting of either an ACK indicating successful reception of the message or a NACK indicating failure of reception of the message, wherein energy used to transmit the acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK;
- and
- wherein the processor sets the energy used to transmit an ACK to be near zero and the processor sets the energy used to transmit a NACK to be approximately four times the energy of an acknowledgement message in a system where the energy required to transmit a NACK and an ACK are equal.
A method for communication in a communication system having at least one terminal in wireless communication with at least one network infrastructure, the method comprising:
- the at least one terminal sending a message to the at least one network infrastructure;
- receiving the message at the at least one network infrastructure;
- after receiving the message, the at least one network infrastructure determines the success or failure in reception of the message and, in response, sends an acknowledgement message to the at least one terminal, the acknowledgement message consisting of either an ACK indicating successful reception of the message or a NACK indicating failure of reception of the message, wherein energy used to transmit the acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK;
- and
- wherein the energy used to transmit an ACK is set near zero and the energy used to transmit a NACK is set approximately four times the energy of an acknowledgement message in a system where the energy required to transmit a NACK and an ACK are equal.
