Abstract
Methods, systems, and devices for wireless communications are described. Techniques described herein support encoding and transmitting of data carrying reference signals (DCRSs according to a lower modulation order and data according to a higher modulation order. A transmitting device may write data bits and DCRS bits into a bitstream according to an interleaving table (e.g., a systematic bit priority mapping (SBPM) interleaver or table). In some examples, the transmitting device may utilize a sub-constellation of the higher modulation order constellation for transmitting the DCRS bits via DCRS REs. In some examples, the transmitting device may skip (e.g., leave unoccupied) entries in the interleaving table corresponding to the LSBs of a DCRS column. In some examples, the transmitting device may write DCRS bits into the bitstream according to a first interleaving table, and may write data bits into the bitstream according to a second interleaving table.
