Embodiment Construction

[0034] Referring now to the drawings, wherein like numerals indicate like parts throughout.

[0035] Exemplary embodiments are now described in detail. While these embodiments are primarily applicable to cellular networks (including but not limited to third generation (3G) Universal Mobile Telecommunications System (UMTS) wireless networks, Long Term Evolution (LTE) wireless networks, and other fourth generation (4G) or LTE-Advanced (LTE) -A) discussed in the context of a wireless network), but one of ordinary skill should recognize that the disclosed embodiments are not limited thereto. In fact, the various disclosed features are applicable and readily applicable to any wireless network that could benefit from the adaptive wake-up procedure described herein.

[0036] review

[0037]Existing cellular-enabled devices (eg, cell phones, smart phones, tablet computers, etc.) base so-called "wake-up" times on component tolerances. In general, these component tolerances represe...

Abstract

Methods and apparatus for adaptively adjusting temporal parameters such as e.g., wake-up times of digital tracking algorithms (such as timing, frequency and power control). In one exemplary embodiment, wake-up times for tracking loops are based on success / error metrics (e.g., Block Error Rate (BLER), Bit Error Rate (BER), Packet Error Rate (PER), Cyclic Redundancy Checks (CRC), etc.) of one or more previous discontinuous reception (DRX) cycles. In a second embodiment, wake-up times for tracking loops are based on residual frequency and timing errors, etc.
