Abstract
Official abstract text for this publication.
To appropriately control UL transmission such as a CSI reporting when communication is performed by applying a different configuration from those of legacy LTE systems, one aspect of a user terminal according to the present invention includes: a transmitting section that transmits first Channel State Information (CSI) and second CSI of different information types to be reported, by using an uplink control channel and/or an uplink shared channel based on timings respectively configured by a base station; and a control section that, when transmission timings of the first CSI and the second CSI overlap, performs control to transmit both or one of the first CSI and the second CSI.
First claim
Opening claim text (preview).
The invention claimed is: 1. A terminal comprising: a processor that, if transmissions of multiple channel state information (CSI) overlap, determines a resource for an uplink control channel based on a number of bits of the multiple overlapping CSI; and a transmitter that transmits at least one of the multiple overlapping CSI by using the uplink control channel, wherein the processor selects a specific uplink control channel format among a plurality of uplink control channel formats configured based on the number of bits of the multiple overlapping CSI. 2. The terminal according to claim 1 , wherein the multiple overlapping CSI include a type I CSI and a type II CSI of different codebooks. 3. The terminal according to claim 1 , wherein the multiple overlapping CSI include periodic CSI and semi-persistent CSI. 4. A radio communication method for a terminal, comprising: if transmissions of multiple channel state information (CSI) overlap, determining a resource for an uplink control channel based on a number of bits of the multiple overlapping CSI; and transmitting at least one of the multiple overlapping CSI by using the uplink control channel, wherein the terminal selects a specific uplink control channel format among a plurality of uplink control channel formats configured based on the number of bits of the multiple overlapping CSI. 5. A system comprising a terminal and base station, wherein: the terminal comprises: a processor that, if transmissions of multiple channel state information (CSI) overlap, determines a resource for an uplink control channel based on a number of bits of the multiple overlapping CSI; and a transmitter that transmits at least one of the multiple overlapping CSI by using the uplink control channel, the base station comprises: a receiver that receives at least one of the multiple overlapping CSI by using the uplink control channel, wherein the processor selects a specific uplink control channel format among a plurality of uplink control channel formats configured based on the number of bits of the multiple overlapping CSI.
