Abstract:
Certain aspects of the present disclosure relate to a method and apparatus for communicating on an uplink between a user equipment and a gNB. In one example, the method and apparatus may include a UE waiting for an NPRACH occasion to transmit an NPRACH preamble, the UE monitoring the search space for (C-RNTI) NPDCCP candidates which carry UL grants, the UE aborting the opportunity to send the NPRACH preamble ifthe physical layer UE receives a UL grant, the UE sending UL data to the gNB, and the UE continuing to monitor the search space for valid C-RNTI NPDCCH candidates for DCI grants. Also, in another example, the UE calculates an NPDCCH search space start timing, monitors a RAR window start timing, and receives the RAR ifthe RAR window starts before the next NPDCCH search space.
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. The UE may be a multi-sim. When both SIMs are associated to the same RAT and/or PLMN, by using the parameter(s) acquired for the first subscription, the time of acquisition of the second subscription (e.g., on power up) becomes shorter. The parameter(s) may include a PSC, SSC, system information, frequency, frame timing and cell selection in WCDMA networks.
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:
Methods and apparatus for selection of a Wireless Local Area Network (WLAN) Access Point (AP) for Long Term Evolution (LTE) WLAN aggregation (LWA) is provided. A Station (STA) receives information from at least one WLAN AP of a plurality of WLAN APs in the STA's vicinity, the information being indicative of a capability of the at least one WLAN AP to support LWA. The STA selects one of the plurality of WLAN APs for connection with the STA in LWA configuration, based at least on the received information.
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.

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:
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 interfrequency 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:
Aspects of managing background public mobile network (BPLMN) searches are described. For example, in an aspect, a user equipment (UE) may determine whether one or more segments of a frequency acquisition from a prior discontinuous reception (DRX) cycle remain to be completed and whether the one or more segments of the frequency acquisition may be performed in a remaining portion of the current DRX cycle. If so, the UE may be configured to perform the one or more segments of the frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time.
