Abstract
Logic circuitry (409) constantly monitors a transmitter (410) to determine if the transmitter (410) is idle. Logic circuitry (409) suppresses all NAKs until data and other channel information is not being transmitted by the transmitter (410) and RF resources are not scarce. Additionally, logic circuitry (409) suppresses all NAKs until a predetermined number of NAKs has been buffered by the logic circuitry (409). More particularly, logic circuitry (409) determines when a number of NAKs will sufficiently fill an over-the-air frame. Once the predetermined number of NAKs has been collected, the logic circuitry (409) will generate the appropriate NAKs.
Claims9
A method of negative acknowledgment (NAK) suppression, the method comprising the steps of:
- determining that a NAK needs to be transmitted;
- determining if data or other channel information currently needs to be transmitted over a channel;
- and
- transmitting the NAK if data and other channel information does not need to be transmitted over the channel, otherwise buffering the NAK.
A method comprising the steps of:
- determining that a NAK needs to be transmitted over a channel;
- determining a number of NAKs currently buffered;
- and
- transmitting the NAKs currently buffered along with the NAK if the predetermined number of NAKs have been buffered, otherwise buffering the NAK.
An apparatus comprising:
- a buffer storing NAKs;
- and
- logic circuitry coupled to the buffer, the logic circuitry having a transmission status of a transmitter as an input and outputting instructions for a NAK generator to generator to generate NAKs based on the transmission status of the transmitter.
