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

Claim 13:
14. A transmitter device for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit, to a receiver device, an initial message associated with a communication using a first code rate that is an overestimated code rate that is greater t ha n a determined code rate associated with a channel,
wherein the first code rate is associated with a first spectral efficiency or a first modulation and coding scheme;
receive, from the receiver device, first feedback information indicating that the communication was not successfully decoded by the receiver device;
transmit, to the receiver device based at least in part on the reception of the first feedback information, one or more retransmissions associated with the communication including a first retransmission,
wherein the first retransmission includes a first number of bits, from a set of bits associated with the communication, the first number of bits being for a code block or a code block group associated with at least one code block or at least one code block group that was not successfully decoded by the receiver device,
wherein the first number of bits lowers an effective code rate of the communication to a second code rate that is associated with a second spectral efficiency or a second modulation and coding scheme, and
wherein the first number of bits lowers the effective code rate of the communication to a next lower modulation and coding scheme according to modulation and coding scheme indices defined by a wireless communication standard; and
receive, from the receiver device, second feedback information indicating that the communication was successfully decoded by the receiver device,
wherein the effective code rate for the communication is based at least in part on a second number of bits included in the initial message and the first number of bits included in the first retransmission.
