FEEDBACK IN FORM OF SEMI-PERSISTENT INFORMATION CSI OVER PUSCH CHANNEL Russian patent published in 2020 - IPC H04L5/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. To enable transmission of semi-persistent channel state information (SP-CSI) over a physical uplink shared channel (PUSCH), a user device (UE) receives a control signaling message, which configures at least one SP CSI report configuration on the PUSCH and identifies reporting interval SP CSI. UE also receives physical layer control signalling for identifying and activating said at least one SP CSI report configuration and transmitting multiple SP CSI reports, wherein the reports are transmitted with periodicity and in accordance with the physical layer control signalling and the control signalling message.

EFFECT: enabling CSI feedback for all possible transmission schemes, providing dynamic switching of transmission schemes for adaptation to a channel.
