Abstract: Various embodiments of a radio frequency front end (RFFE) are disclosed, in one embodiment comprising: a 2G Global System for Mobile telecommunications (GSM) transceiver; a 4G Long Term Evolution (LTE) transceiver; and a combiner coupled to the 2G GSM transceiver and to the 4G LTE transceiver and to a radio head, coupled to the radio head via at least one stream of IQ samples, the at least one stream carrying samples derived from the 2G GSM transceiver and samples derived from the 4G LTE transceiver. The RFFE may be configured to provide downlink for 2G and 4G. The combiner may be configured to upsample 2G signals from the 2G GSM transceiver to a 4G carrier frequency. The RFFE may be configured to transmit both 2G and 4G on a same frequency band.

Abstract: A method and computer readable media are described for providing hybrid functional splits for a system. In one example embodiment a method includes defining, for a system having a Radio Unit (RU) and a Distributed Unit (DU) a Centralized Unit (CU) and an interface protocol between the RU to the DU and to the CU, a plurality of split options for balancing computer power and spectral efficiency, the plurality of split options including a split option 6 in which users are served by a single cell; and a split option 7.x in which users are served by multi-cell joint processing.
