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).

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.
