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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a narrowband Internet of thing (NB-IoT) user equipment (UE). Further, the apparatus may be configured to receive NB reference signals (NRS) on a NB channel during a gap between reception events, perform link quality measurements based on the NRS received during an evaluation time interval, the evaluation time interval being shorter than the gap between the reception events, determine whether a link quality is greater than or equal to a first threshold, during the evaluation time interval, based on the link quality measurements, and determine whether to enable an autonomous reception (RX) sleep mode for a remaining duration of the gap between the reception events based at least in part on determining whether the link quality is greater than or equal to the first threshold value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of master information blocks (MIBs) on a narrowband physical broadcast channel (NPBCH). The UE may determine an NPBCH signal power based at least in part on the plurality of MIBs. The UE may estimate a narrowband reference signal received power (NRSRP) parameter based at least in part on the NPBCH signal power. In some aspects, a base station may determine whether to enable or disable NPBCH-based estimates of an NRSRP parameter for a UE. The base station may transmit, to the UE, an indication of whether NPBCH-based estimates of the NRSRP parameter are enabled or disabled for the UE based at least in part on the determination. Numerous other aspects are provided.

Abstract: A method for authenticating a circuit switched (CS) call on a virtual subscriber identity module (VSIM) includes: authenticating the VSIM for a packet switched (PS) call connection using authentication information obtained from a remote server through a software subscriber identity module (soft-SIM) connection to the remote server; initiating a call connection on a CS radio access technology (RAT) between the VSIM and a first communication network; and authenticating the VSIM CS call connection to the first communication network through the VSIM PS connection in response to an authentication request for the call connection on the CS RAT.

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 communication are described. A user equipment (UE) may receive configuration information from a base station. The UE may determine, based at least in part on the configuration information, a number of subframes available within a random access response (RAR) time window for downlink control channel communications. The UE may modify a random access procedure based on the determined number of subframes available within the RAR time window for the downlink control channel communications. In one example, modifying the random access procedure may include skipping a decoding attempt using a decoding hypothesis. In another example, modifying the random access procedure may include aborting the random access procedure.
