1  ScopeWord‑p. 6

The present document is an introduction to the TSG RAN TS 25.43x series of UMTS Technical Specifications that define the Iub Interface. The Iub interface is a logical interface for the interconnection of Node B and Radio Network Controller (RNC) components of the UMTS Terrestrial Radio Access Network (UTRAN) for the UMTS system.

3  Definitions and abbreviations

3.1  Definitions

For the purposes of the present document, the following terms and definitions apply:
Propagation delay (PD):
it is the round trip propagation delay of the radio signal from the Node B to the UE and back to the BS in one chip resolution.
Timing Advance (TA):
it is the amount of time, expressed in number of chips, by which the transmission of an uplink burst is anticipated by the UE in order to be received by the cell inside the corresponding time slot.
