The C1 series specifies Um point for the 3G TD-SCDMA mobile system. This series defines the minimum level of specifications required for basic connections in terms of mutual connectivity patibility. 3 Scope This specification describes the documents being produced by the CWTS WG1and plete versions expected to be available by end of 1999. This specification gives also general description of the physical layer procedure of the UTRA TDD mode air interface. 4 References References may be made to: a) Specific versions of publications (identi
