Abstract
A configuration for a device to interleave a codeword, where the codeword is based on an enhanced noncoherent error correction code. The apparatus encodes a set of bits based on a noncoherent error correction code to generate a first codeword. The apparatus interleaves the first codeword to permute coded bits of the first codeword into a second codeword. The apparatus transmits the second codeword to a second device.
Claims26
An apparatus for wireless communication at a first wireless device, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- encode a set of bits based on a noncoherent error correction code to generate a first codeword;
- receive, from a second device, a configuration indicating at least one interleaver;
- interleave the first codeword to permute coded bits of the first codeword into a second codeword based on the at least one interleaver;
- and
- transmit, to the second device in a transmission, a first portion and a second portion of the second codeword that is frequency division duplexed or time division duplexed, wherein the transmission does not include a pilot or a demodulation reference signal (DM-RS).
A method of wireless communication of a first device, comprising:
- encoding a set of bits based on a noncoherent error correction code to generate a first codeword;
- receiving, from a second device, a configuration indicating at least one interleaver;
- interleaving the first codeword to permute coded bits of the first codeword into a second codeword based on the at least one interleaver;
- and
- transmitting, to the second device in a transmission, a first portion and a second portion of the second codeword that is frequency division duplexed or time division duplexed, wherein the transmission does not include a pilot or a demodulation reference signal (DM-RS).
An apparatus for wireless communication at a second device, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a first device in a transmission, a first portion and a second portion of a first codeword that is frequency division duplexed or time division duplexed, wherein the transmission does not include a pilot or a demodulation reference signal (DM-RS);
- de-interleave the first codeword to permute coded bits of the first codeword into a second codeword;
- and
- decode, without a channel estimation, the second codeword into a set of bits based on a noncoherent error correction code.
A method of wireless communication of a second device, comprising:
- receiving, from a first device in a transmission, a first portion and a second portion of a first codeword that is frequency division duplexed or time division duplexed, wherein the transmission does not include a pilot or a demodulation reference signal (DM-RS);
- de-interleaving the first codeword to permute coded bits of the first codeword into a second codeword;
- and
- decoding, without a channel estimation, the second codeword into a set of bits based on a noncoherent error correction code.
