Abstract:
1. A transmitter apparatus comprising: a transmitter configured to transmit a first data block having a sequence number using a first modulation and coding scheme utilizing a first plurality of orthogonal frequency division multiplexing (OFDM) subcarriers, the first modulation and coding scheme comprising a first modulation type and a first coding rate; a segmentation device configured to segment the first data block into a plurality of data segments, and to append additional segmentation information that comprises a plurality of segment identifiers (SIDs) that indicate a manner of segmentation of the first data block, wherein an SID is assigned to each of the plurality of data segments, wherein the segmentation device is configured to determine the additional segmentation information subsequent to a Hybrid Automatic Repeat reQuest (HARQ) message requesting retransmission of data in the first data block; and the transmitter further configured to transmit the segments with the plurality of SIDs using the second modulation and coding scheme utilizing a second plurality of OFDM subcarriers, the second modulation and coding scheme comprising a second modulation type and a second coding rate, wherein the first plurality of OFDM subcarriers is different than the second plurality of OFDM subcarriers, the first modulation type is different than the second modulation type, and the first coding rate is different than the second coding rate.
