Abstract
Official abstract text for this publication.
A method and system for including a base station that configures a first user equipment (UE) that is in a radio resource control connected state with the base station. The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method comprising: receiving, by a user equipment (UE), a first radio resource control (RRC) signal from a base station serving the UE, the RRC signaling instructing the UE to transmit a first device-to-device synchronization signal (D2DSS); receiving, by the UE, a second RRC signal from the base station, the second RRC signal identifying a synchronization resource for transmitting the first D2DSS by the UE, wherein the first RRC signal is received independently from the second RRC signal; and transmitting, by the UE, the first D2DSS over the synchronization resource.
