Patent Searching and Data


Title:
RETRANSMISSION PROCESSING METHOD AND EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/171711
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a retransmission processing method and equipment, comprising: a terminal device receives first transmission information sent by a network device, the first transmission information comprising an identifier of at least one piece of transmission data, and the transmission data being a code block or a code block group; and the terminal device instructs a physical layer of the terminal device to generate first feedback information by means of a media access control (MAC) layer, wherein the first feedback information indicates whether it is necessary to retransmit at least one piece of transmission data in the transmission block corresponding to the transmission data. When downlink retransmission is needed, the terminal device may instruct the physical layer of the terminal device, by means of the MAC layer, to generate each piece of feedback information for the decoding result of each piece of transmission data, and the network device may thus learn whether the decoding result of each code block or code block group in one TB is successful, thus allowing the network device to subsequently retransmit each code block or code block group.
