On the downlink, UE 110 may receive downlink signals transmitted by base station 120 and/or 130. A receiver (RCVR) 1126 may condition (e.g., filter, amplify, frequency downconvert, and digitize) the received signal and provide input samples. A demodulator (Demod) 1116 may process (e.g., descramble, channelize, and demodulate) the input samples and provide symbol estimates. A decoder 1118 may process (e.g., deinterleave and decode) the symbol estimates and provide decoded data and signaling sent to UE 110. Encoder 1112, modulator 1114, demodulator 1116, and decoder 1118 may be implemented by a modem processor 1110. These units may perform processing in accordance with a radio technology (e.g., LTE) used by the cellular network. A controller/processor 1130 may direct the operation of various units at UE 110.
