Radio communication apparatus and radio communication system

A CQI control unit 401 inputs, to a subchannel selecting unit 402, subchannel estimation values for report bands which are based on control information received from a control information separating unit 221, at report timings based on the control information. The subchannel selecting unit 402 selects a predetermined number (M) of subchannels on the basis of the received subchannel estimation values, and inputs information indicating the selected subchannels and the qualities of the selected channels to a CQI constructing unit 403. Based on a predetermined format, the CQI constructing unit 403 constructs CQIs by using the qualities of the selected channels and the information indicating the selected channels, and inputs the CQIs to the coding unit 210. Here, as the channel quality, an average value of each of SNR, SINR, and CINR of subcarriers belonging to the subchannel is used. Alternatively, the poorest quality among the subcarriers included in the subchannel may be used as the channel quality of the subchannel, or information indicating the MCS required by the receiver may be used as the channel quality. In this way, it is possible to provide a method that enables the transmission of CQIs at their optimum intervals even in a case of a system using multiple discontinuous bands.

Uplink signaling of direct current (DC) tone location in new radio (NR)

Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.
