METHOD AND APPARATUS FOR HANDLING CONTENTION BASED DATA TRANSMISSION IN A WIRELESS COMMUNICATION NETWORK

WIPO Patent Application WO/2023/027434

A1

A method for handling contention based data transmission (CBDT) in a wireless communication network is disclosed. The method includes: allocating CBDT resource blocks to a plurality of user equipment (UEs); receiving data bits and control bits on one or more resource blocks among the allocated CBDT resource blocks from a group of UEs among the plurality of UEs; determining whether each of the received data bits and control bits is decoded successfully; transmitting a negative acknowledgment message to each UE in the group of UEs based on determining that the received control bits are decoded successfully, and the received data-bits are not decoded successfully; and storing the decoded data bits which are not received successfully in a hybrid　automatic repeat request (HARQ) buffer.
