TRANSMISSION BLOCK SIZE DETERMINATION METHOD AND DEVICE, AND SYNCHRONIZATION METHOD, DEVICE, AND SYSTEM

摘要

Disclosed are a transmission block size determination method and device, and synchronization method, device, and system, the synchronization method comprising: an eNB obtaining the number of frequency domain physical resource blocks (PRBs) and the modulation and coding scheme (MCS) index of an UE; determining the size of a temporary transmission block according to the number of frequency domain PRBs and the MCS index; determining, according to the size of the temporary transmission block and/or the size of the transmission time interval (TTI) bundling, the scale factor for the size of the TTI bundling; determining, according to the scale factor and the size of the temporary transmission block, the size of a TTI bundling transmission block; notifying the UE the scale factor of the size of the TTI bundling transmission block, the number of the frequency domain PRBs, and the MCS index, or notifying the UE the number of the frequency domain PRBs and the MCS index, and triggering the UE to synchronize the transmission block size. The present invention solves the synchronization problem of the size of TTI bundling transmission blocks, thereby enhancing uplink coverage.
