Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for identifying narrowband reference signal (NRS) tones that are to be received in association with a scheduled paging occasion, wherein the NRS tones are configured to be received via a non-anchor carrier regardless of whether a page is to be received in connection with the scheduled paging occasion; and receive the NRS tones via the non-anchor carrier based at least in part on the configuration. Numerous other aspects are provided.

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 configuration to enable a base station to adjust an error rate for paging and to advertise such error rate to UEs, in order to optimize or reduce network paging resources. The apparatus determines a target miss rate for paging on a downlink narrowband control channel. The apparatus transmits an indication of the target miss rate to one or more UEs. The indication is transmitted in system information or a dedicated downlink channel.

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 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: There is a need to support HARQ retransmission for narrow-band communications. The present disclosure provides a solution by supporting a HARQ retransmission timer for narrow-band communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method for wireless communication at a user equipment may include receiving, by a user equipment (UE), a hybrid automatic repeat request (HARQ) retransmission timer, the HARQ retransmission timer indicates a time interval, identifying, by the (UE), data for uplink transmission, and starting, by the UE and after expiration of the HARQ retransmission timer, a random access procedure to obtain an uplink grant for the data.

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.
