Apparatus, systems, methods, and computer products suitable for use in an advanced digital baseband processor

摘要

The present disclosure relates to an advanced digital baseband processor for a base station in a cellular communications network. In general, the advanced digital baseband processor integrates multiple Radio Access Technologies (RATs). As used herein, a RAT is a radio access technology as defined by a corresponding standard. For example, in one embodiment, RATs integrated by the advanced digital baseband processor include a Code Division Multiple Access (CDMA) voice RAT (e.g., 3GPP2 CDMA 1xRTT or 3GPP2 CDMA 1xAdvanced) as well as a CDMA Data Only, or Data Optimized, (DO) RAT (e.g., 3GPP2 CDMA EV-DO or 3GPP2 CDMA EV-DO Rev B). In another embodiment, the RATs integrated by the advanced digital baseband processor also include 3GPP Long Term Evolution (LTE). The RATs given above are only examples. The advanced digital baseband processor may integrate additional or alternative RATs.
