Abstract
Official abstract text for this publication.
A user terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating start of report of semi-persistent channel state information (SP-CSI (Semi-Persistent Channel State Information) report), and a control section that determines timing of the SP-CSI report, based on whether or not there is relation between timing of a feedback report for reception of the information and the timing of the SP-CSI report. According to one aspect of the present disclosure, SP-CSI report and/or detection can be appropriately controlled even when SP-CSI report activation is indicated by using MAC CEs (Medium Access Control Control Elements).
First claim
Opening claim text (preview).
What is claimed is: 1. A terminal comprising: a receiving section that receives information indicating start of Semi-Persistent Channel State Information (SP-CSI) report; and a control section that control to transmit the SP-CSI report on Physical Uplink Control Channel (PUCCH) resource after a transmission of Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) for reception of the information. 2. The terminal according to claim 1 , wherein the control section assumes that there is no relation between the timing of the feedback report and the timing of the SP-CSI report, and determines the timing of the SP-CSI report, regardless of the timing of the feedback report. 3. A radio communication method for a terminal, the radio communication method comprising: receiving information indicating start of Semi-Persistent Channel State Information (SP-CSI) report; and controlling to transmit the SP-CSI report on Physical Uplink Control Channel (PUCCH) resource after a transmission of Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) for reception of the information. 4. A base station comprising: a transmitting section that transmits information indicating start of Semi-Persistent Channel State Information (SP-CSI) report; and a control section that control to receive the SP-CSI report on Physical Uplink Control Channel (PUCCH) resource after a transmission, from the terminal, of Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) for reception of the information.
