Abstract

Official abstract text for this publication.

In order to suppress deterioration of the communication quality also in the case of transmitting uplink data and uplink control information using an uplink shared channel in the future radio communication system, one aspect of a user terminal of the present invention has a transmitting section that transmits uplink data and uplink control information, and a control section that controls so as to select one of puncturing processing and rate matching processing to apply to the uplink data, based on an indication from a base station and/or a predetermined condition, in the case of multiplexing the uplink data and the uplink control information into an uplink shared channel to transmit.

First claim

Opening claim text (preview).

The invention claimed is: 1. A terminal comprising: a transmitter that transmits uplink data and uplink control information using an uplink shared channel; and a processor that controls a resource amount to perform rate matching processing or puncturing processing, wherein the processor controls the resource amount, to perform the rate matching processing or the puncturing processing, based on a number of bits of the uplink control information and an amount of the uplink data scheduled on the uplink shared channel, and when the uplink control information is HARQ-ACK, the processor selects one of the rate matching processing and the puncturing processing based on whether a payload of the HARQ-ACK exceeds a non-zero fixed value or is the non-zero fixed value or less. 2. The terminal according to claim 1 , wherein the processor controls the resource amount, to perform the rate matching processing or the puncturing processing, based on the number of bits of the uplink control information, the amount of the uplink data, and a coding rate of the uplink control information. 3. A radio communication method for a terminal comprising: controlling a resource amount to perform rate matching processing or puncturing processing, wherein the controlling of the resource amount is performed based on a number of bits of uplink control information and an amount of uplink data scheduled on an uplink shared channel, and when the uplink control information is HARQ-ACK, selecting one of the rate matching processing and the puncturing processing based on whether a payload of the HARQ-ACK exceeds a non-zero fixed value or is the non-zero fixed value or less; and transmitting the uplink data and the uplink control information using the uplink shared channel. 4. A base station comprising: a processor that controls reception of an uplink shared channel in which a resource amount to perform rate matching processing or puncturing processing is controlled based on a number of bits of uplink control information and an amount of uplink data scheduled on the uplink shared channel, wherein, when the uplink control information is HARQ-ACK, the processor determines that one of the rate matching processing and the puncturing processing is to be selected based on whether a payload of the HARQ-ACK exceeds a non-zero fixed value or is the non-zero fixed value or less; and a receiver that receives the uplink data and the uplink control information transmitted using the uplink shared channel. 5. A system comprising a terminal and a base station, wherein the terminal comprises: a transmitter that transmits uplink data and uplink control information using an uplink shared channel; and a processor that controls a resource amount to perform rate matching processing or puncturing processing, wherein the processor controls the resource amount, to perform the rate matching processing or puncturing processing, based on a number of bits of the uplink control information and an amount of the uplink data scheduled on the uplink shared channel, and when the uplink control information is HARQ-ACK, the processor selects one of the rate matching processing and the puncturing processing based on whether a payload of the HARQ-ACK exceeds a non-zero fixed value or is the non-zero fixed value or less, and the base station comprises: a receiver that receives the uplink data and the uplink control information transmitted using the uplink shared channel.
