Abstract
Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.
Claims14
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one memory comprising computer-executable instructions;
- and
- one or more processors configured to execute the computer-executable instructions and cause the apparatus to:
- obtain payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
- determine a long sequence allocated to the UE, wherein the long sequence has a length greater than a number of tones in each RB, the long sequence is selected from a set of long sequences that allow for multiplexing with other UEs using the same interlace of the RBs, and each of the long sequences exhibits local orthogonality with other long sequences in the set;
- and
- transmit the payload bits using a set of tones of the RBs and the long sequence allocated to the UE.
