SYNCHRONIZATION OF A DEVICE IN COMMUNICATIONS |
| 摘要 |
A method for synchronizing communication devices comprises receiving, in a communication device (102), a first synchronization signal transmitted from a network apparatus (101). Based on the first synchronization signal, communication device (102) performs a coarse synchronization process. Based on the coarse synchronization process, the communications device (102) transmits a synchronization scheduling request message to the network apparatus (101). The communication device (102) receives (306), from the network apparatus (101), a second synchronization signal, together with a scheduling grant, at a predetermined time window with reference to the scheduling request, and transmits (307) data from the communication device (102) to the network apparatus (101), based on the scheduling grant. |

1. A method for synchronizing communication devices in a communications system, the method comprising
receiving, in a communication device, a first synchronization signal transmitted from a network apparatus; based on the first synchronization signal, performing a coarse synchronization process in the communications device; transmitting a scheduling request message from the communication device to the network apparatus, based on the coarse synchronization process performed in the communications device; receiving, in the communication device from the network apparatus or a further communication device, a second synchronization signal; transmitting data from the communication device to the network apparatus, based on a scheduling grant. |
