RADIO STATION SYSTEM, RADIO TERMINAL AND METHODS THEREIN Russian patent published in 2021 - IPC H04W4/00 H04L29/04 H04W16/32 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to communication. For this purpose, radio station (2) transmits configuration information (501) to radio terminal (1). Configuration information (501) indicates, based on the cell-by-cell, at least one specific cell through which radio terminal (1) is allowed to perform at least one of the data transmission and receiving data on a radio carrier used for uplink transmission or downlink transmission or for both types through a packet data convergence protocol (PDCP) common layer (402). In this way, in the radio communication architecture, tight interaction of two different Radio Access Technologies (RAT) is provided, which ensures the said result.

EFFECT: technical result consists in simplification of indication to a radio terminal (UE) of a specific cell, through which UE should perform uplink (UL) transmission.
