Abstract

Methods are disclosed for communication devices capable of simultaneous transmission and reception, wherein a first method is for reception of a packet comprising a header and a payload and a second method is for transmission of a packet comprising a header and a payload. The second method comprises transmitting at least a part of the header. The first method comprises receiving at least a part of the header, attempting to decode the part of the header, and (when the part of the header is successfully decoded) transmitting a header acknowledgement signal. The second method comprises monitoring receipt of a header acknowledgement signal, and (when absence of the header acknowledgement signal is detected) interrupting the transmission of the packet and scheduling the packet for retransmission. Corresponding apparatuses, transceivers, communication devices and computer program products are also disclosed.

First claim

The invention claimed is:

1. A method for a communication device capable of simultaneous transmission and reception, wherein the method is for transmission of a packet comprising a header and a payload, the method comprising the communication device:
transmitting at least a part of the header;
monitoring receipt of a header acknowledgement signal;
when absence of the header acknowledgement signal is detected, interrupting the transmission of the packet and scheduling the packet for retransmission; and
when a header acknowledgement signal is received and includes an indication of a recommended packet modulation and coding scheme, using the recommended packet modulation and coding scheme for transmission of a subsequent packet.

2. The method of claim 1 , further comprising:
transmitting the header in entirety;
monitoring receipt of a premature packet acknowledgment signal; and
when the premature packet acknowledgement signal is detected, interrupting the transmission of the packet.

3. The method of claim 1 , further comprising:
transmitting the payload;
monitoring receipt of a packet acknowledgement signal; and
when absence of the packet acknowledgement signal is detected, scheduling the packet for retransmission.

4. The method of claim 1 , wherein the part of the header comprises a header field indicative of a packet recipient address.

5. A non-transitory computer readable recording medium storing a computer program product for controlling a communication device for transmission of a packet comprising a header and a payload, the computer program product comprising program instructions which, when run on processing circuitry of the communication device, causes the communication device to:
transmit at least a part of the header;
monitor receipt of a header acknowledgement signal;
when absence of the header acknowledgement signal is detected, interrupt the transmission of the packet and schedule the packet for retransmission; and
when a header acknowledgement signal is received and includes an indication of a recommended packet modulation and coding scheme, using the recommended packet modulation and coding scheme for transmission of a subsequent packet.

6. An apparatus for a communication device capable of simultaneous transmission and reception, wherein the apparatus is for transmission of a packet comprising a header and a payload, the apparatus comprising controlling circuitry configured to cause:
processing circuitry;
memory containing instructions executable by the processing circuitry whereby the apparatus is operative to function as controlling circuitry configured to cause:
transmission of at least a part of the header;
monitoring of receipt of a header acknowledgement signal; and
responsive to detection of absence of the header acknowledgement signal, interruption of the transmission of the packet and scheduling of the packet for retransmission; and
when a header acknowledgement signal is received and includes an indication of a recommended packet modulation and coding scheme, using the recommended packet modulation and coding scheme for transmission of a subsequent packet.

7. The apparatus of claim 6 , wherein the controlling circuitry is further configured to cause:
transmission of the header in entirety;
monitoring of receipt of a premature packet acknowledgment signal; and
responsive to detection of the premature packet acknowledgement signal, interruption of the transmission of the packet.

8. The apparatus of claim 6 , wherein the controlling circuitry is further configured to cause:
transmission of the payload;
monitoring of receipt of a packet acknowledgement signal; and
responsive to detection of absence of the packet acknowledgement signal, scheduling of the packet for retransmission.

9. The apparatus of claim 6 , wherein the controlling circuitry is further configured to cause reception of an indication of a recommended packet modulation and coding scheme together with the header acknowledgement signal, and use of the recommended packet modulation and coding scheme for transmission of an immediately subsequent packet.
