Claim of US Patent No. 10,716,099

1. A communication system including a host computer comprising:processing circuitry configured to provide user data; and
a communication interface configured to forward user data to a cellular network for transmission to a user equipment, UE,
wherein the UE comprises a radio interface and processing circuitry, the UE's processing circuitry configured to:
be configured with at least two physical uplink control channel opportunities, PUCCH opportunities, by semi-static signaling, each of the at least two PUCCH opportunities identifying uplink, UL, resources to be used for transmitting control information to a communication network;
receive an assignment of radio resources to be used for receiving a downlink, DL, transmission from a network node of the communication network;
receive an acknowledgement resource indication, ARI, indicating one of the configured at least two PUCCH opportunities to be used for transmitting control information associated with the DL transmission; and
transmit the control information associated with the DL transmission to the network node on at least a subset of the UL resources identified by the indicated PUCCH opportunity,
wherein the indicated PUCCH opportunity includes one or more of a PUCCH format, a PUCCH duration, a PUCCH payload size, or a PUCCH bandwidth,
wherein the at least two PUCCH opportunities identify one or more of different PUCCH formats, different PUCCH durations, different PUCCH payload sizes, or different PUCCH bandwidths.
