Abstract:
Techniques are provided for utilizing notch filters to overcome narrowband jamming. An example method for determining a range to a satellite vehicle with a receiver includes receiving a signal from the satellite vehicle, determining one or more notch filter configurations, determining a pseudorandom noise code and a doppler frequency associated with the signal, determining a codephase correction value based at least on the one or more notch filter configurations, the pseudorandom noise code and the doppler frequency, and computing the range to the satellite vehicle based at least in part on the signal and the codephase correction value.
Abstract:
A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engages in a downlink positioning session, a sidelink positioning session, or both with one or more first network entities, and transmits at least one positioning capability report to one or more second network entities, the at least one positioning capability report including one or more parameters indicating joint downlink and sidelink capabilities of the UE to process both downlink positioning reference signals (DL-PRS) and sidelink positioning reference signals (SL-PRS).
Abstract:
A user equipment (UE) reports its own position using reference location information messages and relative location information messages. An example method performed by a first UE includes determining a first location of the first UE based on positioning measurements, transmitting a reference location information message indicating the first location, determining one or more subsequent locations of the first UE based on subsequent positioning measurements, and transmitting one or more relative location information messages, each of the one or more relative location information messages indicating a subsequent location for the UE based on relative information with respect to the first location.
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:
Various embodiments for conducting a public land mobile network (PLMN) search for a plurality of radio access technologies (RATs) on a mobile communication device may include profiling a frequency space to identify one or more frequency bands that may be utilized by one of the plurality of RATs and determining, according to a priority ordering of the plurality of RATs, a RAT that utilizes each identified frequency band. The mobile communication device may add, for each RAT in the plurality of RATs, the identified frequency bands utilized by each RAT to exclude lists associated with other RATs in the plurality of RATs. The mobile communication device may then conduct a PLMN search for each RAT in the plurality of RATs utilizing the exclude lists associated with each RAT.

Abstract:
Various embodiments include methods for scheduling reception activities on a wireless communication device having a first receive chain and a second receive chain. Various embodiments may include identifying a first reception activity and a second reception activity of a first subscription scheduled on the first receive chain, in which a duration of the second reception activity is longer than a duration of the first reception activity. The wireless communication device may determine whether the first reception activity and the second reception activity can be performed concurrently on the first receive chain, and schedule the second reception activity on the second receive chain in response to determining that the first reception activity and the second reception activity cannot be performed concurrently on the first receive chain.
