USER EQUIPMENT, BASE STATIONS, AND METHODS FOR CONFIGURABLE DOWNLINK CONTROL INFORMATION FORMAT Russian patent published in 2023 - IPC H04W72/04 H04W72/231 H04W72/232 

FIELD: communication systems.

SUBSTANCE: user equipment (UE) comprises a receiving unit configured to receive a radio resource control (RRC) configuration containing a first parameter used to determine the bit field size of the antenna ports field in the first downlink control information (DCI) format, the second parameter, used to determine the bit field size of the carrier indicator field in the first DCI format, and a third parameter indicating the first allocation table used to determine the bit field size of the time domain resource assignment in the first DCI format. The transmission block is configured to transmit data on the uplink (PUSCH) based on the definition of the first DCI format, in accordance with the first parameter, the second parameter, and the third parameter, of the first transmission of the physical shared channel. The receiving unit is also configured to receive an RRC configuration comprising a fourth parameter used to determine the bit field size of the antenna ports field in the second DCI format, a fifth parameter used to determine the bit field size of the carrier indicator field in the second DCI format, a sixth parameter used to determine the bit field size of the priority indicator field in the second DCI format; and a seventh parameter indicating a second allocation table used to determine the bit field size of the time domain resource assignment in the second DCI format. The transmission unit is configured to transmit data based on the definition of the second DCI format, in accordance with the fourth parameter, the fifth parameter, the sixth parameter, and the seventh parameter, of the second PUSCH transmission.

EFFECT: increase in the flexibility and efficiency of data exchange.
