Abstract: A system and method of scheduling radio resources in a packet-switched wireless communications network. A plurality of data packets from a plurality of users are placed in a First-In-First-Out (FIFO) queue and are sequentially selected and analyzed for transmission. If a selected packet has an instantaneous radio channel quality (C/I) greater than a historical channel quality value, the packet is transmitted. If the instantaneous C/I is not greater than the historical value, it is determined whether the selected packet has been held for longer than a threshold time period. If so, the selected packet is transmitted. If neither condition is met, the selected packet is temporarily held in its position in the queue while analyzing the next packet for transmission. If no packets qualify for transmission, the packet in the first position is transmitted. After each transmission, the analysis starts again at the head of the queue.

Abstract: A system, method, and apparatus for assuring the availability of packet sequence numbers in an adaptive hybrid-ARQ coding scheme are presented. In a hybrid-ARQ coding scheme with multiple forward error correction (FEC) rates, a parameter is defined based on the highest data rate and the lowest data rate, whereby the parameter, N, is equivalent to the number of packets required to retransmit a packet which was initially transmitted at the highest FEC rate now at the lowest FEC rate. A header module which assembles the packet headers increments the packet number of packets in sequential increments which assure the availability of N sequence numbers. The availability of N sequence numbers permits the coding sequence to retransmit a packet using the lowest FEC rate without disrupting the sequential ordering of each packet.
