Patent ID: 8780768

Claim:
A wireless communication method comprising steps of: receiving a signal comprising frames, each of the frames comprising subframes; configuring a plurality of M×N automatic gain control (AGC) loops, each AGC loop of the plurality of AGC loops being configured for modulo M×N tasks operation, each task having a predetermined task duration, M of the tasks per subframe, M being an integer greater than one, N being periodicity of guaranteed downlink (DL) subframes within the frames, wherein said each AGC loop includes a predetermined task delay in front of an input of an accumulator of said each AGC loop, the predetermined task delay being equal to an integer number of tasks; operating said each AGC loop; correlating the received signal with a known synchronization signal to detect a pattern of the known synchronization signal within the received signal; and determining, in response to detection of the pattern of the known synchronization signal within the received signal, subframe timing of the received signal.
