Abstract: An apparatus and method are provided to re-configure an existing low-jitter phase locked loop (PLL) circuit for fast start-up during system wake-up. During system start-up, a feed-back path of the PLL is disconnected to independently control the VCO frequency. This independently controlled VCO then injects energy into a resonator (e.g., a crustal oscillator) for its fast start-up. Once a resonance frequency of the resonator is detected and an oscillation builds up in the resonator, a VCO control voltage is stored. The PLL feedback is then restored and the stored VCO control voltage is applied to perform phase-locking operation. Since the PLL control voltage is already set to the desired operating point, the PLL lock time is very small.

Abstract: Methods, systems, and devices are described for low latency communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system and may send triggers to initiate communications using a dedicated resource in a wireless communications network that supports transmissions having a first subframe type and a second subframe type, the first subframe type comprising symbols of a first duration and the second subframe type comprising symbols of a second duration that is shorter than the first duration. Communications may be initiated by transmitting a trigger from the UE or eNB using the dedicated resource, and initiating communications following the trigger. The duration of time between the trigger and initiating communications can be significantly shorter than the time to initiate communications using legacy LTE communications.
