Multi-carrier radio link protocol supervision in a radio communication system
First Claim
1. An apparatus configured to receive packet-formatted data in a plurality of instances, the packet-formatted data in each instance having an overall sequence and including a plurality of portions each of which has a respective link sequence, the apparatus comprising:
- a processor; and
a memory including computer program code, the memory and computer program code configured to, with the processor, cause the apparatus in at least one of the plurality of instances to at least;
receive portions of the packet-formatted data over respective subchannels of a radio communication system;
detect that a portion of the packet-formatted data is missing based upon the overall sequence;
time a time period; and
generate a request for retransmission of the missing portion of the packet-formatted data when the apparatus fails to receive the missing portion of the packet-formatted data before the time period times out.

Abstract
A method is provided for facilitating efficient usage of radio capacity in a radio communication system including a communication station operable to receive, over a plurality of subchannels of the radio communication system. In this regard, the packet-formatted data has an overall sequence, and is divided into a plurality of portions receivable by the communication station over respective subchannels, where each portion has a respective link sequence. The method includes detecting missing packet-formatted data at the communication station based upon the overall sequence or at least one of the link sequences. Then, when the missing packet-formatted data is detected based upon the overall sequence, a time period is timed, and when the communication station fails to receive the missing packet-formatted data before the step of timing times out, retransmission of the missing packet-formatted data is requested.

7. A first apparatus comprising:
-
a processor; and a memory including computer program code, the memory and computer program code configured to, with the processor, cause the first apparatus in at least one of a plurality of instances to at least; receive a request for retransmission of a missing portion of packet-formatted data from a second apparatus configured to receive packet-formatted data in the plurality of instances, the packet-formatted data in each instance having an overall sequence and including a plurality of portions each of which has a respective link sequence, wherein in the respective at least one of the plurality of instances, the second apparatus is configured to; receive portions of the packet-formatted data over respective subchannels of a radio communication system; detect that a portion of the packet-formatted data is missing based upon the overall sequence; time a time period; and generate the request for retransmission when the second apparatus fails to receive the missing portion of the packet-formatted data before the time period times out; and retransmit the missing portion of the packet-formatted data to the second apparatus in response to the request for retransmission. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for receiving packet-formatted data at an apparatus configured to receive packet-formatted data in a plurality of instances, the packet-formatted data in each instance having an overall sequence and including a plurality of portions each of which has a respective link sequence, the method comprising in at least one of the plurality of instances:
-
receive portions of the packet formatted data over respective subchannels of a radio communication system; detecting that a portion of the packet-formatted data is missing based upon the overall sequence or at least one of the link sequences; timing a time period; and generating a request for retransmission of the missing portion of the packet-formatted data when the apparatus fails to receive the missing portion of the packet-formatted data before the time period times out. - View Dependent Claims (14, 15, 16, 17, 18)
