Abstract:
Techniques for determining a position of a mobile device are provided. A method according to these techniques includes obtaining assistance data comprising information for cells associated with a plurality of wireless transmitters of a wireless communications network based on the coarse location of the mobile device, selecting a plurality of the cells from the assistance data, wherein selecting the plurality of cells includes identifying sets of colocated cells and selecting one cell from each of the colocated sets of cells; measuring signals from the plurality of cells to generate positioning signal measurements; and sending the positioning signal measurements to a location server. A colocated set of cells may include a narrowband cell and a non-narrowband cell, and the narrowband wireless cell may comprise a narrowband Internet of Things (NB-IoT) cell and a non-narrowband cell colocated with the NB-IoT cell at an Evolved Node B (eNodeB).
Abstract:
A method for performing one or more measurements by a mobile communication device having a first radio-frequency (RF) chain associated with a first subscription and a second RF chain associated with a second subscription includes: determining that the mobile communication device is in a connected mode on the first subscription; determining whether the second RF chain associated with the second subscription is available; and in response to determining that the second RF chain associated with the second subscription is available, utilizing the second RF chain associated with the second subscription to perform at least one of an inter-frequency measurement and an inter-radio access technology measurement on the first subscription.
Abstract:
Efficient RAT frequency scanning based on false alarms is described. A first RAT associated with multiple frequency bands, and a first frequency band among the multiple frequency bands, may be selected. A first signal scan associated with the first RAT may be performed in the first frequency band to identify a candidate signal in the first frequency band. Determining that the candidate signal is not associated with the first RAT may signal a false alarm, and information related to the candidate signal may be stored as false alarm information. A second RAT associated with at least one of the multiple frequency bands, and a second frequency band among the at least one of the multiple frequency bands, may be selected based on the stored false alarm information. A second signal scan associated with the second RAT in the second frequency band may be performed.
Abstract:
Techniques and apparatus for early termination of decoding of communication channels for power saving in narrowband devices are provided. One technique includes monitoring for one or more first repetitions of at least one communication channel from a base station. The device determines, based on the monitoring, whether to refrain from monitoring for one or more second repetitions of the at least one communication channel. The device enters a low power mode if the determination is to refrain from monitoring for the one or more second repetitions of the at least one communication channel.
Abstract:
A method for performing a cell search that includes: identifying a first frequency used by a first base station (BS) on which a mobile communication device is camped on a first subscription; receiving one or more messages from the first BS on the first frequency; identifying a second frequency used by a second BS that is an inter-frequency neighbor of the first BS based at least in part on the one or more messages; and determining to exclude from the cell search on a second subscription at least one of the first frequency and the second frequency.
Abstract:
According to various embodiments, there is provided a method for a wireless communication device having at least one Subscriber Identity Module (SIM) associated with a subscription to manage communications over the subscription. The method may include determining a value of a computer processing unit (CPU) load of the wireless communication device, the CPU load based on data operations of the at least one SIM and contributing to a thermal state of the wireless communication device. The method may further include determining whether the value of the CPU load is greater than a load threshold. The method may further include, in response to determining that the value of the CPU load is greater than the load threshold, performing a variable tuneaway at the at least one SIM during which the at least one SIM is configured to halt the data operations, a length of the variable tuneaway based on the value of the CPU load.
Abstract:
Systems and methods are described herein for managing acquisitions including, but not limited to, executing a first portion of a first acquisition process for acquiring service for a first subscription of a user equipment (UE); obtaining at least one parameter as a result of executing the first portion of the first acquisition process; and executing a second portion of a second acquisition process for acquiring service for a second subscription of the UE using the at least one parameter.
Abstract:
Disclosed are systems and methods for continuous inter-frequency measurement reconfigurations in a DC-HSUPA User Equipment (UE). In one aspect, the system may configure the UE to perform intra-frequency measurements on a frequency f1 and inter-frequency measurements on a frequency f2 in a dual carrier (DC) downlink (DL) mode and a single carrier (SC) uplink (UL) mode. The system may then reconfigure the UE to operate in a DC UL mode and continuing to perform inter-frequency measurements on the frequency f2 in the DC UL mode. The system may then reconfigure the UE to operate in the SC UL mode and continuing to perform inter-frequency measurements on frequency f2 in the SC UL mode.
Abstract:
Embodiments include systems and methods for managing power resources of an Internet of Everything (IoE) device. A processor of the IoE device may monitor an uplink interference over time. The device processor may calculate wireless communication parameters based on the monitored uplink interference over time, and may store in a memory the calculated wireless communication parameters. The device processor may calculate a transmit power based on one or more stored wireless communication parameters associated with a transmit time, and may transmit to a communication network a request to establish a communication link using the calculated transmit power.
