Abstract

To appropriately control a plurality of CSI reports of different types, a user terminal according to one aspect of the present disclosure includes: a transmitting section that transmits channel state information (CSI) reports of different types; and a control section that, when transmission durations of a plurality of the CSI reports overlap, drops a given CSI report according to priority or multiplexes a given CSI report on a given uplink channel, based on a type of each of the plurality of the CSI reports and a type of an uplink channel used for transmission of each of the plurality of the CSI reports.

Claims (21)

1. A terminal comprising:

a processor, wherein if transmission durations of a plurality of channel state information (CSI) reports overlap, then the processor determines whether the plurality of CSI reports are multiplexed based on a report type of each CSI report and an uplink channel type used in transmission of each CSI report; and

a transmitter that transmits at least one of the plurality of CSI reports,

wherein if the plurality of CSI reports are CSI reports of the same type that utilize a Physical Uplink Control Channel (PUCCH), and if a multi-CSI-PUCCH resource list is configured by a higher layer, then the processor multiplexes the plurality of CSI reports with a PUCCH resource configured by the multi-CSI-PUCCH resource list.

2. The terminal according to claim 1 , wherein the processor drops at least one CSI report based on a code rate of the plurality of CSI reports.

3. A radio communication method for a terminal comprising:

if transmission durations of a plurality of channel state information (CSI) reports overlap, then determining whether the plurality of CSI reports are multiplexed based on a report type of each CSI report and an uplink channel type used in transmission of each CSI report; and

transmitting at least one of the plurality of CSI reports,

wherein if the plurality of CSI reports are CSI reports of the same type that utilize a Physical Uplink Control Channel (PUCCH), and if a multi-CSI-PUCCH resource list is configured by a higher layer, the plurality of CSI reports is multiplexed with a PUCCH resource configured by the multi-CSI-PUCCH resource list.

4. A base station comprising:

a processor, wherein if transmission durations of a plurality of channel state information (CSI) reports overlap, the processor indicates, by configuring a multi-CSI-PUCCH resource list by a higher layer, to determine whether the plurality of CSI reports are multiplexed based on a report type of each CSI report and an uplink channel type used in transmission of each CSI report; and

a receiver that receives at least one of the plurality of CSI reports,

wherein if the plurality of CSI reports are CSI reports of the same type that utilize a Physical Uplink Control Channel (PUCCH), and if a multi-CSI-PUCCH resource list is configured by the higher layer, the processor indicates to multiplex the plurality of CSI reports with a PUCCH resource configured by the multi-CSI-PUCCH resource list.

5. A system comprising a terminal and a base station, wherein:

the terminal comprises:

a first processor, wherein if transmission durations of a plurality of channel state information (CSI) reports overlap, then the first processor determines whether the plurality of CSI reports are multiplexed based on a report type of each CSI report and an uplink channel type used in transmission of each CSI report; and

a transmitter that transmits at least one of the plurality of CSI reports,

wherein if the plurality of CSI reports are CSI reports of the same type that utilize a Physical Uplink Control Channel (PUCCH), and if a multi-CSI-PUCCH resource list is configured by a higher layer, then the first processor multiplexes the plurality of CSI reports with a PUCCH resource configured by the multi-CSI-PUCCH resource list; and

the base station comprises:

a second processor indicates, by configuring the multi-CSI-PUCCH resource list by the higher layer, to determine whether the plurality of CSI reports are multiplexed; and

a receiver that receives at least one of the plurality of CSI reports.
