    Abstract: Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity. The UE may then prioritize the channel state processes and/or may transmit one or more non-current reports.

    Abstract: Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which PAPR for an input of an AGC in a wireless receiver is generated. The AGC may provide a gain-controlled signal to a correlator when the PAPR of the input does not exceed the threshold ratio and may clamp the gain of the gain-controlled signal when PAPR of the input is large. A large PAPR may cause termination of search for a signal of interest in a current channel. The search may be resumed in a non-adjacent channel.
