LOW-DELAY HYBRID AUTOMATIC REQUEST FOR REPETITION OF UPLINK TRANSMISSION Russian patent published in 2022 - IPC H04L1/18 

FIELD: wireless communication.

SUBSTANCE: said technical result is achieved by that user equipment (UE) comprises a receiving circuit, configured to receive a radio resource control message containing first information used to configure the number of repetitions and periodicity, wherein the number of repetitions is configured for transport block (TB) transfers; receiving circuitry receives a radio resource control message containing second information used to configure traceability of a symbol, and monitors a first physical downlink control channel (PDCCH) with cyclic redundancy check (CRC), scrambled using a temporary cell radio network identifier (C-RNTI). Receiving circuit tracks a second PDCCH with a CRC scrambled using a second RNTI different from the C-RNTI. UE also comprises a transmission circuit, configured to perform TB transmissions on a physical uplink shared data channel (PUSCH) based on the first information.

EFFECT: high efficiency of data exchange.
