User terminal, base station apparatus, and radio communication method
To appropriately communicate a control channel even when communication is performed by applying a configuration of the control channel different from those of legacy LTE systems, a user terminal according to the present invention includes: a reception section that receives a downlink control channel transmitted by each of a plurality of control resource sets; and a control section that controls monitoring of a downlink control channel candidate, and the control section controls allocation of a number of downlink control channel candidates to each of the control resource sets assuming that the number of downlink control channel candidates configured to a combination of the control resource sets in a given time unit does not exceed terminal capability.
1. A terminal comprising:
a processor that, by selecting a UE specific search space set after initially selecting a UE common search space set, determines downlink control channel candidates to be monitored, such that a number of the determined downlink control channel candidates does not exceed a maximum value of a number of downlink control channel candidates monitored per slot; and
a receiver that monitors the determined downlink control channel candidates.
2. A terminal according to claim 1 , wherein, when selecting the UE specific search space set, the processor controls to select a UE specific search space set having a smallest index among a plurality of UE specific search space sets in ascending order.
3. A terminal according to claim 1 , wherein the maximum value is based on a subcarrier spacing.
4. A radio communication method for a terminal, comprising:
by selecting a UE specific search space set after initially selecting a UE common search space set, determining downlink control channel candidates to be monitored, such that a number of the determined downlink control channel candidates does not exceed a maximum value of a number of downlink control channel candidates monitored per slot; and
monitoring the determined downlink control channel candidates.
5. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a processor that, by selecting a UE specific search space set after initially selecting a UE common search space set, determines downlink control channel candidates to be monitored, such that a number of the determined downlink control channel candidates does not exceed a maximum value of a number of downlink control channel candidates monitored per slot; and
a receiver that monitors the determined downlink control channel candidates; and
the base station comprises:
a transmitter that transmits the downlink control channel candidates.
