receive, from a base station, a configuration of one or more reference signal (RS) resources of an RS resource set, the one or more RS resources being associated with an index modulation technique including a plurality of uplink (UL) or downlink (DL) information bits; and

transmit, to the base station, or receive, from the base station, the plurality of UL or DL information bits, the plurality of UL or DL information bits including at least one of one or more first bits or one or more second bits,

at least one of the one or more RS resources being selected based on at least one of the one or more first bits or the one or more second bits, wherein the configuration comprises a bit split within the plurality of UL or DL information bits of the at least one of the one or more first bits or the one or more second bits or wherein the at least one processor coupled to the memory is further configured to transmit a configuration recommendation comprising the bit split.
