Embodiment approach
[0046] 1. Configure the entire extended Pitocell as a cell, such as image 3 shown.
[0047] 2. An eCPRI link is used between the host (BBU) and the extension unit (RHUB). The BBU deploys the high PHY function, and the low PHY function is deployed to the extension unit, that is, each extension unit deploys the low PHY function.
[0048] 3. Configure the number of SSB resources in the cell (the number of SSB transmissions within 5ms) equal to the number of extension units connected to the cell (in the example above, the number of SSB transmissions within 5ms is 4).
[0049] 4. The host configures specific SSB resources and corresponding ssb index for each expansion unit, as shown in the above figure, ssbindex is 0~3;
[0050] 5. Each extension unit sends an SSB signal at a corresponding timing according to the configured SSB resources, carrying the corresponding ssbindex. The SSB data sent by the expansion unit is finally sent SSB signal through the connected RF unit;
