4.12 Macro-diversity procedure

25.2243GPPPhysical layer procedures (TDD)TS

When signalled by higher layers, the UE shall combine transmissions on signalled transport channels from multiple radio links. UTRAN shall only indicate that a transport channel on a radio link may be combined with a transport channel on another radio link when those transport channels do not occupy the same time slot. UTRAN shall transmit identical transport blocks on the multiple radio links on the transport channels that may be combined. UTRAN may multiplex onto a CCTrCH other transport channels with transport channels that can be combined. The TTIs of transmissions that may be combined shall start at the same SFN on each of the multiple radio links.
