Abstract

The embodiment of the invention discloses an interleaving and subcarrier mapping method supporting unequal modulation and a related device, where interleavers comprise a first interleaver and a second interleaver, the interleavers are used for determining the sequence of information bits borne on subcarriers of a first RU and a second RU, and the modulation modes of the first RU and the second RU are different; the first interleaver is used for inputting information bits according to rows, the column number of the first interleaver is M1 + M2, and the row number of the first interleaver is the maximum value of N1 and N2; N1 and M1 are determined by the number of subcarriers of the first RU, and N2 and M2 are determined by the number of subcarriers of the second RU; and the second interleaver is used for receiving the information bits output by the first interleaver according to the column and carrying out staggered mapping on the information bits. According to the interleaver provided by the embodiment of the invention, the information bits of a plurality of RUs with different modulation and coding strategies can be interleaved, so that the hardware structure of the communication device is simplified.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to an interleaving and subcarrier mapping method supporting unequal modulation and a related device. Background technique [0002] The demands of modern wireless communication services on the channel capacity and communication performance of the communication system are always increasing. In order to improve the channel capacity and communication performance of the wireless communication system, in the Institute of Electrical and Electronics Engineers (IEEE) 802.11be protocol standard, the same user is allowed to be allocated multiple resource units (resource unit, RU) . In order to further improve the allocation flexibility and spectrum utilization of the wireless communication system, when a user can be allocated multiple RUs, multiple RUs of the same user can be configured with different modulation and coding schemes (Modulation and Coding Scheme, MCS), Tha...
