Title:
PUNCTURING AND RETRANSMISSION TECHNIQUES FOR ENCODED TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2018/076733
Kind Code:
A1
Abstract:
Various aspects of the disclosure relate to retransmission techniques for communication of information (e.g., for wireless communication). In some aspects, if a device's first transmission including punctured encoded data fails, the device's second transmission (e.g., in response to a NAK) may involve transmitting the punctured bits. In some aspects, the coding rate used for encoding the data for the first transmission is selected to meet an error rate (e.g., a block error rate) for the second transmission. The second transmission may also include at least some of the encoded data. In some aspects, the puncturing may be performed according to a puncture pattern that is generated based on bit error probabilities of bit positions for encoded data.
