Systems and methods for controlling radio frequency communication receivers
A method of controlling a receiver of radio frequency communications includes intervals between the reception of a data packet header and an acknowledgement sent by the receiver being constant, and, once a packet has been correctly received, circuits of the receiver are put into standby for a duration corresponding to the interval after each reception of a header of same rank as that of the correctly received packet.
1 . A method of controlling a receiver of radio frequency communications, the method comprising:
sending acknowledgements at constant intervals after receiving respective data packet headers; and
in response to correctly receiving a packet, putting circuits of the receiver into standby for a duration corresponding to the interval after each reception of a header of same rank as that of the correctly received packet.
2 . The method according to claim 1 , further comprising, after each reception of a header having a rank different than that of the correctly received packet, keeping active the circuits of the receiver during at least part of the corresponding interval.
3 . The method according to claim 1 , further comprising arranging a data packet of each of the intervals in a protocol data unit.
4 . The method according to claim 3 , wherein the intervals have a size greater than a maximum predetermined size of protocol data units.
5 . The method according to claim 4 , wherein each of the intervals comprises a clock adjustment time between the protocol data unit and the respective acknowledgement sent by the receiver.
6 . The method according to claim 5 , further comprising putting the circuits of the receiver into standby during the clock adjustment time.
7 . The method according to claim 1 , further comprising activating the circuits of the receiver for the sending of the acknowledgements.
8 . A communication module configured for radio frequency communications, the communication module comprising:
a receiver configured to receive data packet headers; and
a transmitter communicatively coupled to the receiver and configured to send acknowledgements at constant intervals after the receiver receives the respective data packet headers;
the receiver further configured to, in response to correctly receiving a packet, put circuits of the receiver into standby for a duration corresponding to the interval after each reception of a header of same rank as that of the correctly received packet.
9 . The communication module according to claim 8 , wherein, after each reception of a header having a rank different than that of the correctly received packet, the circuits of the receiver remain active during at least part of the corresponding interval.
10 . The communication module according to claim 8 , wherein a data packet of each of the intervals is arranged in a protocol data unit.
11 . The communication module according to claim 10 , wherein the intervals have a size greater than a maximum predetermined size of protocol data units.
12 . The communication module according to claim 11 , wherein each of the intervals comprises a clock adjustment time between the protocol data unit and the respective acknowledgement sent by the receiver.
13 . The communication module according to claim 12 , wherein during the clock adjustment time, the circuits of the receiver are put into standby.
14 . The communication module according to claim 8 , wherein the circuits of the receiver are active for the sending of the acknowledgements.
15 . A radio frequency communication system comprising:
a first communication module configured to transmit data packets each having a data packet header indicating their respective rank; and
a second communication module comprising a receiver and configured to:
send acknowledgements at constant intervals after receiving respective data packet headers; and
in response to correctly receiving a packet, put circuits of the receiver into standby for a duration corresponding to the interval after each reception of a header of same rank as that of the correctly received packet.
16 . The radio frequency communication system according to claim 15 , wherein the first communication module comprises a second receiver, and is configured to:
send second acknowledgements at second constant intervals after receiving respective second data packet headers; and
in response to correctly receiving a second packet, put second circuits of the second receiver into standby for a second duration corresponding to the second interval after each reception of a second header of same rank as that of the correctly received second packet.
17 . The radio frequency communication system according to claim 15 , wherein the first communication module and the second communication module are identical.
18 . The radio frequency communication system according to claim 15 , wherein the first and/or the second communication modules comprise a radio frequency signal transmission block and a radio frequency signal reception block.
19 . The radio frequency communication system according to claim 18 , wherein the radio frequency signal transmission block and the radio frequency signal reception block, of the first and/or the second communication module, are coupled to a respective antenna via a switch coupling the respective antenna alternatingly to the radio frequency signal transmission block and the radio frequency signal reception block.
20 . The radio frequency communication system according to claim 15 , wherein the first and/or the second communication modules comprise a buffer data storage module configured to store the acknowledgements and/or the data packets.
