Method and apparatus for intermittent communication
When an intermittent communication mode is entered, a check period and intermittent reception mode period thereof are determined and the intermittent reception mode is reentered through an ignored process, that is, when the intermittent reception mode is entered, the check period and intermittent reception mode period are determined in overhead 101 thereof and data 102, 103 is transmitted/received thereafter through an ignored process.
1. An intermittent communication method performed by a communication terminal, comprising:
receiving, from an access point, a configuration signal to configure the communication terminal to operate in an intermittent communication mode comprising a sleep period; and
monitoring intermittently a control channel in accordance with a configuration of the intermittent communication mode, the configuration being set according to the configuration signal, wherein:
upon the communication terminal receiving, from the access point, a NACK signal relating to a new transmission in an automatic repeat request mode, regardless of whether the communication terminal is presently monitoring the control channel or not, the communication terminal receives an ACK/NACK signal from the access point for a retransmission of the new transmission, wherein:
the communication terminal secures an ACK/NACK frame for receiving the ACK/NACK signal for the retransmission.
2. The method according to claim 1 , wherein the configuration signal includes information for indicating a monitoring period in the intermittent communication mode.
3. The method according to claim 1 , wherein the control channel is a broadcast channel (BCH).
4. A communication terminal, comprising:
a radio reception section configured to receive from an access point a configuration signal to configure the communication terminal to operate in an intermittent communication mode comprising a sleep period; and
a control section configured to monitor intermittently a control channel in accordance with a configuration of the intermittent communication mode, the configuration being set according to the configuration signal,
wherein:
upon the communication terminal receiving from the access point, a NACK signal relating to a new transmission in an automatic repeat request mode, regardless of whether the communication terminal is presently monitoring the control channel or not the communication terminal receives an ACK/NACK signal from the access point for a retransmission of the new transmission, wherein:
the communication terminal secures an ACK/NACK frame for receiving the ACK/NACK signal for the retransmission.
5. The communication terminal according to claim 4 , wherein the configuration signal includes information for indicating a monitoring period in the intermittent communication mode.
6. The communication terminal according to claim 4 , wherein the control channel is a broadcast channel (BCH).
7. An access point, comprising:
a transmission section configured to:
transmit a configuration signal to a communication terminal to configure the communication terminal to operate in an intermittent communication mode in which the communication terminal monitors intermittently a control channel in accordance with a configuration of the intermittent communication mode, the configuration being set according to the configuration signal and the intermittent communication mode comprising a sleep period,
transmit a NACK signal to the communication terminal relating to a new transmission in an automatic repeat request mode, and
transmit an ACK/NACK signal to the communication terminal for a retransmission of the new transmission, wherein the ACK/NACK signal is received by the communication terminal regardless of whether the communication terminal is presently monitoring the control channel or not, wherein:
the communication terminal secures an ACK/NACK frame for receiving the ACK/NACK signal for the retransmission.
8. The access point according to claim 7 , wherein the configuration signal includes information for indicating a monitoring period in the intermittent communication mode.
9. The access point according to claim 7 , wherein the control channel is a broadcast channel (BCH).
