Abstract: PROBLEM TO BE SOLVED: To provide more quick and accurate initial acquisition methods in communication systems and in particular time division duplex (TDD) systems such as those found in LTE.SOLUTION: A method includes: running a plurality of predetermined amplifier gain states for a low noise amplifier (LNA) 304a, 304b during initial acquisition in a time division duplex (TDD) system; and determining acquisition of a received signal on the basis of searching across the plurality of predetermined amplifier gain states.

Abstract: A METHOD FOR CORRECTING OPERATION OF THE SLEEP OSCILLATOR (116) OF A WIRELESS COMMUNICATIONS DEVICE (100). SLEEP OSCILLATOR FREQUENCY IS ESTIMATED (412) SO AS TO COMPENSATE FOR ESTIMATED TEMPERATURE INDUCED ERRORS. IN ESTIMATING TEMPERATURE INDUCED ERRORS, ERRORS (504) IN SLEEP OSCILLATOR FREQUENCY ARE TREATED AS BEING TEMPERATURE INDUCED ERRORS (522), BUT PROBABLE MULTIPATH ERRORS ARE BOUNDED (410, 520) TO PREDETERMINED SLEEP CLOCK ERROR MAXIMA (602) CORRESPONDING TO SLEEP DURATION OVER WHICH THE ERROR OCCURRED.
