Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A first device for wireless communications, comprising:
a memory; and
at least one processor coupled to the memory, wherein the first device is configured to:
select a first index modulation scheme or a second index modulation scheme to encode a set of reference signal resources to include a second subset of information bits based on values associated with a first subset of information bits, wherein the first index modulation scheme and the second index modulation scheme are different types of multi-mode reference signal index modulation schemes, and wherein the set of reference signal resources convey a set of information bits to a second device via one or more reference signals, and wherein the set of information bits comprises the first subset of information bits and the second subset of information bits;
encode the set of information bits by application of, to a set of reference signals to be transmitted using the set of reference signal resources, the first index modulation scheme for a first value of the first subset of information bits and the second index modulation scheme for a second value of the first subset of information bits, wherein a respective bit value associated with the second subset of information bits is encoded based on a respective bit value associated with the first subset of information bits; and
transmit, to the second device, the encoded set of information bits via the set of reference signals.
