Abstract

Provided are a user equipment, base station and wireless communication methods related to uplink control information mapping in physical uplink resources in NR (New Radio access technology). A user equipment comprises: circuitry operative to map, in physical resource blocks (PRBs) for Physical Uplink Shared Channel (PUSCH), Uplink Control Information (UCI) to one or more available resource elements according to their distances with resource elements where reference signals are mapped in one or more of time domain, frequency domain and spatial domain; and a transmitter operative to transmit the UCI and the reference signals in PUSCH on the PRBs to a base station.

Claims19

Dependent claims

An integrated circuit, comprising:

reception circuitry, which, in operation, controls receiving Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) bits, Channel State Information (CSI) bits and data in a Physical Uplink Shared Channel (PUSCH) by using Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) in 14 OFDM symbols;
and
demodulation circuitry, which, in operation, controls demodulating the HARQ-ACK bits;
wherein the HARQ-ACK bits are mapped to two non-consecutive first OFDM symbols in the 14 OFDM symbols which are different from two non-consecutive second OFDM symbols,
wherein demodulation reference signals (DMRSs) are mapped to a part of assigned subcarriers of the two non-consecutive second OFDM symbols,
wherein one of the two non-consecutive first OFDM symbols is adjacent to and later than one of the two non-consecutive second OFDM symbols, and another one of the two non-consecutive first OFDM symbols is adjacent to and later than another one of the two non-consecutive second OFDM symbols,
wherein the CSI bits are mapped to a third OFDM symbol which is different from the two non-consecutive first OFDM symbols, and
wherein the HARQ-ACK bits are mapped to distributed resource elements in a frequency domain within allocated resource blocks.
