Techniques for switching orthogonal and non-orthogonal sequence based noncoherent uplink control transmissions

A method for wireless communications at a transmitter, comprising:

• identifying a payload to include in a noncoherent transmission to a receiver;
• determining to transmit the noncoherent transmission using an orthogonal sequence codebook a non-orthogonal sequence codebook based on a size of the payload, wherein the orthogonal sequence codebook is used based on the size of the payload being less than or equal to a threshold, and wherein the non-orthogonal sequence codebook is used based on the size of the payload being greater than the threshold;
• and
• transmitting the noncoherent transmission to the receiver based on whether the noncoherent transmission is to use the orthogonal sequence codebook or the non-orthogonal sequence codebook, wherein the orthogonal sequence codebook and the non-orthogonal sequence codebook are associated with the noncoherent transmission.

An apparatus for wireless communications at a transmitter, comprising:

• means for identifying a payload to include in a noncoherent transmission to a receiver;
• means for determining to transmit the noncoherent transmission using an orthogonal sequence codebook or a non-orthogonal sequence codebook based on a size of the payload, wherein the orthogonal sequence codebook is used based on the size of the payload being less than or equal to a threshold, and wherein the non-orthogonal sequence codebook is used based on the size of the payload being greater than the threshold;
• and
• means for transmitting the noncoherent transmission to the receiver based on whether the noncoherent transmission is to use the orthogonal sequence codebook or the non-orthogonal sequence codebook, wherein the orthogonal sequence codebook and the non-orthogonal sequence codebook are associated with the noncoherent transmission.

A non-transitory computer-readable medium having code for wireless communications stored thereon that, when executed by a transmitter, causes the transmitter to:

• identify a payload to include in a noncoherent transmission to a receiver;
• determine to transmit the noncoherent transmission using an orthogonal sequence codebook or a non-orthogonal sequence codebook based on a size of the payload, wherein the orthogonal sequence codebook is used based on the size of the payload being less than or equal to a threshold, and wherein the non-orthogonal sequence codebook is used based on the size of the payload being greater than the threshold;
• and
• transmit the noncoherent transmission to the receiver based on whether the noncoherent transmission is to use the orthogonal sequence codebook or the non-orthogonal sequence codebook, wherein the orthogonal sequence codebook and the non-orthogonal sequence codebook are associated with the noncoherent transmission.
