TECHNIQUES FOR TRANSMITTING AND RECEIVING SYNCHRONIZATION SIGNALS OVER AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND |
摘要 |
Techniques are described for wireless communication. A first method may include receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal, and monitoring the unlicensed radio frequency spectrum band during the time window to receive a synchronization signal from a base station. A second method may include transmitting an indication of a time window associated with a transmission of a synchronization signal; performing a plurality of clear channel assessments (CCAs) on an unlicensed radio frequency spectrum band during the time window; and transmitting the synchronization signal over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based at least in part on a result of at least one of the CCAs. |

1. A method for wireless communication, comprising:
receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal; and monitoring the unlicensed radio frequency spectrum band during the time window to receive the synchronization signal from a base station. |
