Physical (PHY) layer solutions to support use of mixed numerologies in the same channel

摘要

A wireless transmit/receive unit (WTRU), using mixed numerologies, may, in a first codeword, map a first set of bits to a higher order modulation scheme and a second set of bits to a lower order scheme, and transmit the first codeword. The WTRU may determine that data of the first codeword is to be re-transmitted on a second codeword, containing the same number of bits as the first codeword. In the second codeword, the WTRU may map a first set of bits to the lower order scheme and a second set of bits to the higher order scheme. The first set of bits of the second codeword may contain the same number of bits as the second set of bits of the first codeword and may contain at least a subset of data in the first set of bits of the first codeword. The WTRU may transmit the second codeword.
