Abstract
Support for multicast and broadcast data transmissions and acknowledgement feedback for the transmissions are being considered in 5G new radio (NR). Resource allocation techniques are provided to allocate uplink control channel resources for acknowledgement of downlink multicast/broadcast (MC/BC) data transmissions. An apparatus, such as a user equipment, receives a multicast/broadcast (MC/BC) configuration indicating a first physical uplink control channel (PUCCH) resource set for transmitting MC/BC acknowledgment (ACK)/negative acknowledgment (NACK), and a unicast configuration indicating a second PUCCH resource set for transmitting unicast ACK/NACK feedback. The apparatus also receives MC/BC data from a base station. The apparatus determines a first PUCCH resource from the first PUCCH resource set for transmitting MC/BC ACK/NACK feedback in response to the received MC/BC data and based on the received MC/BC configuration. The apparatus transmits the MC/BC ACK/NACK feedback to the base station in the determined first PUCCH resource.
