Ultra Mobile Broadband of 3GPP2

Abstract

Ultra Mobile Broadband (UMB) of Third Generation Partnership Project 2 (3GPP2) considers OFDMA and all-IP-based network to fulfill the ITU vision for next generation services in order to enable the convergence of IP-based voice, broadband data, multimedia, information technology, entertainment, and consumer electronic services. The UMB is being designed to offer economical support for a large variety of services that require extremely low latency, low jitter, and high spectral efficiencies to address a large cross section of advanced mobile broadband services.

3GPP2’s convergence to UMB follows an evolutionary path in the family of CDMA2000 standards with recent Flash-OFDM (see Sect. 5.7) input as seen in Fig. 12.1. UMB is therefore a candidate for existing or new spectrum allocations with its scalable bandwidth feature up to 20 MHz. UMB enhances the performance and capabilities by combining the best aspects of CDMA, TDM, OFDM, and OFDMA with Multiple Input Multiple Output (MIMO) and Space Division Multiple Access (SDMA) advanced antenna techniques.
