HARQ PROCEDURE FOR UPLINK FOR MTS OPERATION Russian patent published in 2018 - IPC H04L1/08 H04L1/16 H04L1/18 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to the field of communication. Claimed solution introduces variable repetition levels for controlling and transmitting data on the physical control channel for the downlink for communication between the machines, for example, the M-PDDCH. When the wireless end device detects and correctly decodes a message contained in the physical control channel for the downlink for communication between machines that requests retransmissions, wireless end device performs adaptive retransmissions on the uplink according to the retransmission format that is determined by the message. Retransmission format determines at least one of the modulation and coding rate for retransmissions, the frequency resource for retransmissions, and the number of repetitions.

EFFECT: possibility of using different levels of repetition of control and data transmissions.
