    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: 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.

    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. Aspects of the present disclosure describe a quick scanning method to reject global synchronization channel numbers (GSCNs) that do not include a synchronization signal block (SSB). The quick scanning method utilizes down-sampling techniques to reduce complexity associated with scanning many GSCNs for an SSB. For example, a user equipment (UE) may down-sample a signal to obtain a coarse signal subset (e.g., by using coarse bin sizes, sampling a portion of symbols). The UE may perform a fast Fourier Transform, along with one or more data processing techniques, to obtain a spectrogram corresponding to the signal. While the spectrogram may represent the signal in the frequency domain with reduced resolution, and may include energy information corresponding to different frequencies. The UE may utilize the spectrogram to examine frequencies corresponding to GSCNs to detect if an SSB is present.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for measurements for narrow-band (NB) Internet of Things (IoT) devices. A user equipment (UE) may receive a cell-specific reference signal (CRS) during a paging occasion and via a non-anchor carrier. The UE may process the CRS by determining and/or making quality measurements of the paging carrier. The quality measurements may be used to determine whether a paging occasion should be terminated early to conserve UE power and to prevent an extended “on” duration during the discontinuous receive cycle of the UE. In some examples, the UE may combine statistics and/or measurements based on processing of both the CRS and a narrow-band reference signal (NRS).
