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 is disclosed of providing dynamic Physical Downlink Control Chanel (PDCCH) power allocation, comprising: dividing a transmit power over all resource elements (REs) in a subframe at a first symbol time; determining how many REs will be in use at a second symbol time; determining how much additional power will be available at the second symbol time; and dividing and allocating at least a portion of the determined additional power over REs assigned for PDCCH resources for use during the second symbol time.
