METHOD AND APPARATUS FOR EFFICIENT USAGE OF DAI BITS FOR eIMTA IN LTE

An apparatus for wireless communications in a time division duplex (TDD) based network, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine at least one of a parameter for a hybrid automatic repeat request (HARQ) message bundling or a HARQ message codebook, wherein the parameter for the HARQ message bundling is determined based on a size of a downlink association set of subframes detected by a user equipment, and the HARQ message codebook is determined based on at least one of the size of the downlink association set of subframes or a size of a dynamic set of subframes excluding one or more flexible uplink subframes;
• and
• transmit one or more HARQ messages based on at least one of the parameter or the HARQ message codebook.

A computer program product, comprising:

• a computer-readable medium comprising code for:
• determining at least one of a parameter for a hybrid automatic repeat request (HARQ) message bundling or a HARQ message codebook, wherein the parameter for the HARQ message bundling is determined based on a size of a downlink association set of subframes detected by a user equipment, and the HARQ message codebook is determined based on at least one of the size of the downlink association set of subframes or a size of a dynamic set of subframes excluding one or more flexible uplink subframes;
• and
• transmitting one or more HARQ messages based on at least one of the parameter or the HARQ message codebook.
