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.
Claims34
An apparatus for wireless communications by a user equipment (UE), comprising:
- a memory;
- and
- a processor coupled with the memory, the memory and the processor configured to:
- obtain payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
- determine a group of the RBs available to the UE;
- and
- transmit the payload bits using the determined group of the RBs, wherein the transmitting comprises modulating different RBs of the group of the RBs by different payload bits.
A method for wireless communications by a user equipment (UE), comprising:
- obtaining payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
- determining a group of the RBs available to the UE;
- and
- transmitting the payload bits using the determined group of the RBs, wherein the transmitting comprises:
- modulating different RBs of the group of the RBs by different payload bits.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for obtaining payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
- means for determining a group of the RBs available to the UE;
- and
- means for transmitting the payload bits using the determined group of the RBs, wherein the means for transmitting comprises:
- means for modulating different RBs of the group by different payload bits,
- means for transmitting at least a first bit of the payload bits using a first set of RBs of the group of the RBs and a first cyclic shift;
- and
- means for transmitting at least a second bit of the payload bits using a second set of RBs of the group of the RBs and a second cyclic shift.
A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by a processor of a user equipment (UE), cause the UE to perform a method of wireless communications, comprising:
- obtaining payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
- determining a group of the RBs available to the UE;
- and
- transmitting the payload bits using the determined group of the RBs, wherein the transmitting comprises:
- modulating different RBs of the group by different payload bits,
- transmitting at least a first bit of the payload bits using a first set of RBs of the group of the RBs and a first cyclic shift;
- and
- transmitting at least a second bit of the payload bits using a second set of RBs of the group of the RBs and a second cyclic shift.
