USER EQUIPMENT, BASE STATIONS AND METHODS Russian patent published in 2021 - IPC G06F15/16 H04L1/18 

FIELD: wireless communication systems.

SUBSTANCE: invention relates to wireless communication systems. The user equipment (UE) has a higher-level processor configured to configure a short processing time; a physical downlink control channel (PDCCH) receiver configured to receive the PDCCH in subframe n; a physical downlink shared data channel (PDSCH) receiver configured to receive, in subframe n, a PDSCH corresponding to the PDCCH; and an uplink receiver configured to send back, in subframe n + k, a hybrid automatic repeat request (HARQ-ACK) acknowledgment corresponding to the PDSCH, where if the PDCCH is a PDCCH in the common search space, k is k1, in in case the PDCCH is a PDCCH in a UE-specific search space, k is equal to k2 and k2 is less than k1.

EFFECT: invention increases flexibility and efficiency of wireless communication systems.
