    Abstract: Systems, apparatuses, and methods for early termination of paging search in CSS. A user equipment (UE) may search a common search space (CSS) for a paging indication that may be repeated, up to and including, a maximal number of times in the CSS. A receive power of a reference signal (RS) may be measured for a paging candidate for a number of repetitions, which may be associated with a partial time-frequency region of the CSS. The UE may terminate the paging search based at least on the receive power of the RS and may declare no paging is present without monitoring or searching the full CSS associated with the maximal number of repetitions.

    Abstract: A user equipment (UE) performs wireless communication by starting a scan of an absolute radio frequency channel number (ARFCN) configured for performing a narrowband communication. The UE determines, based on a spectral characteristic of a phase of a signal in the ARFCN, whether a cellular communication is deployed in the ARFCN. The UE may then terminate the scan of the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is deployed in the ARFCN. Alternatively, the UE may proceed with a synchronization signal search on the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is not deployed in the ARFCN.

    Abstract: Aspects of the disclosure relate to a user equipment (UE) for wireless communication. The UE wakes to monitor for a wakeup signal (WUS) having a maximum WUS duration and configured to indicate an upcoming transmission of a paging signal corresponding to the WUS. The UE detects a reference signal tone energy from tones carrying reference signals, detects a WUS tone energy from tones designated for carrying the WUS, and determines whether the WUS is present or absent based on the WUS tone energy and the reference signal tone energy. The UE then transitions to a sleep state prior to an end of the maximum WUS duration when the WUS is determined to be absent. Alternatively, the UE remains awake when the WUS is determined to be present and receives the paging signal corresponding to the WUS. Other aspects, features, and embodiments are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is to scan one or more frequency bands during a cell acquisition procedure. The UE may receive one or more over-the-air signals, each of the one or more over-the-air signals having a respective bandwidth that includes a corresponding plurality of channels from a frequency band of the one or more frequency bands. The UE may process individual ones of the one or more over-the-air signals. The UE may evaluate, in corresponding batches for each of the individual ones of the one or more over-the-air signals, each of the corresponding pluralities of channels for cell acquisition. The UE may acquire a cell via batch-wise evaluation of the corresponding pluralities of channels.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a device, such as an internet of things (IoT) device, may include a configuration or software (e.g., in baseband) that is common for multiple applications of the device. In some aspects, the device may select a setting for at least some if not each of a set of parameters associated with or defining a device profile of the device based on an application of the device. The device may perform a mapping procedure to map the settings for the parameters associated with the device profile to one or more baseband configurations or baseband handles and the device may customize the baseband of the device using the one or more baseband configurations. As such, the device may operate or communicate using the baseband that is customized based on the device profile and application of the device.
