Claim of US Patent No. 10,893,519

1. A terminal device, comprising:a processor and non-transitory machine-readable storage medium containing instructions that, when executed on the processor, are capable of causing the terminal device to perform:
determining at least one set of downlink control channel candidates from sets of downlink control channel candidates including:
a first set of downlink control channel candidates that is to target Quality of Service (QoS) requirements of Ultra-Reliable and Low-Latency Communication (URLLC) communication including a first target block error rate (BLER) threshold, that maps to a first set of aggregation levels, and that uses a first number of control information bits, and
a second set that is to target QoS requirements of enhanced Mobile BroadBand (eMBB) including a second target BLER threshold higher than the first target BLER threshold, that maps to a second set of aggregation levels, and that uses a second number of control information bits more than the first number of control information bits; and
detecting a downlink control channel in the determined at least one set of downlink control channel candidates, wherein the determined at least one set of downlink control channel candidates is mapped to the QoS requirements of URLLC communication.
