METHOD AND DEVICE FOR INFORMATION PROCESSING Russian patent published in 2023 - IPC H04W72/12 

FIELD: wireless communication.

SUBSTANCE: downlink control information (DCI) is transmitted, which contains a first indication field, which is used to carry hybrid automatic repeat request (HARQ) response information. Here, if the DCI also contains a second indication field, then the second indication field is used to carry a trigger notification to perform random access or early data transmission (EDT). By transferring the second indication field and trigger notification to the DCI, the terminal does not need to blindly search the entire PDCCH search space for a long time, thereby saving the power consumption of the terminal.

EFFECT: increased flexibility in the data exchange mode between the terminal and the base station due to the fact that the PDCCH control signalling supports not only the contention-free access mode, but also contention-based random access.
