Resource mapping to handle bursty interference

摘要

Resource mapping and coding schemes to handle bursty interference are disclosed that provide for spreading the modulated symbols for one or more transmission code words over more symbols in the time-frequency transmission stream. Certain aspects allow for the modulated symbols to be based on bits from more than one code word. Other aspects also provide for re-mapping code word transmission sequences for re-transmissions based on the number of re-transmissions requested by the receiver. Additional aspects provide for layered coding that uses a lower fixed-size constellation to encode/decode transmissions in a layered manner in order to achieve a larger-size constellation encoding. The layered encoding process allows the transmitter and receiver to use different coding rates for each coding layer. The layered encoding process also allows interference from neighboring cells to be canceled without knowledge of the actual constellation used to code the interfering neighboring signal.

主权项

1. A method of wireless communication, comprising:
encoding, at a transmitter, a plurality of bits for one or more code blocks of a transmission; interleaving, by the transmitter, the plurality of bits of each of the one or more code blocks across two or more symbols in a time-frequency transmission stream, wherein the interleaving includes interleaving the plurality of bits of each of the one or more code blocks across two or more subframes of the time-frequency transmission stream; and transmitting, by the transmitter to a receiver, the time-frequency transmission stream.
