Title:
METHOD FOR SENDING DATA, METHOD FOR RECEIVING DATA, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/247847
Kind Code:
A1
Abstract:
The present application provides a method for sending data, a method for receiving data, and a communication device. According to the sending method, a data segment is generated by a sending terminal, the data segment comprises header information and data portions of a plurality of CBs obtained by partitioning a TB, the data portions of the plurality of CBs and N sub-PDUs comprised in an MAC PDU have positional mapping relationship, and the header information of each CB is used for indicating the positional mapping relationship between the CB and the corresponding sub-PDU thereof. The sending terminal sends the TB carrying the data segment. Thus, at a receiving terminal, if the TB is wrong upon CRC, the receiving terminal obtains a correct CB by obtaining the position of each CB and performing CRC decision at the CB granularity. By parsing the header information of the correct CB, the receiving terminal learns the positional mapping relationship between the correct CB and a sub-PDU, and acquires the complete sub-PDU from the correct CB, so as to achieve data transfer at the sub-PDU granularity, thereby facilitating improving the performance of a wireless communication system.
