MasterInformationBlock-SL field descriptions |
|---|
|
directFrameNumber Indicates the frame number in which SLSS and SL-BCH are transmitted. The subframe in the frame corresponding to directFrameNumber is indicated by directSubframeNumber. |
|
inCoverage Value TRUE indicates that the UE transmitting the MasterInformationBlock-SL is in E-UTRAN coverage. |
|
sl-Bandwidth Parameter: transmission bandwidth configuration. n6 corresponds to 6 resource blocks, n15 to 15 resource blocks and so on. |
