SYSTEMS AND METHODS FOR COMMUNICATION BETWEEN MAC LAYER AND PHYSICAL LAYER FOR TRANSMISSIONS Russian patent published in 2021 - IPC H04L5/00 

FIELD: wireless communication.

SUBSTANCE: group of inventions relates to wireless communication systems. Proposed are a wireless communication apparatus (UE) (300, 400), a network node (eNB) with a medium access control (MAC) layer (410) and a physical (PHY) layer (430), configured to send/resend a transmission. The MAC layer (410) sends transmissions to the PHY layer (430) for transmission by the PHY layer (430) to the remote wireless communication apparatus (300, 400). The PHY layer (430) receives the transmission from the MAC layer (410) and attempts to send the transmission. The PHY layer (430) additionally indicates to the MAC layer (410) whether the attempt to send the transmission by the PHY layer (430) was successful. In response to the indication, the MAC layer (410) determines whether the attempt to send the transmission by the PHY layer (430) was successful. The MAC layer (410) then selectively indicates to the PHY layer (430) whether an attempt to resend the transmission should be made in response to said indication.

EFFECT: increasing the throughput and conserving the electrical power.
