Enhanced cellular connectivity via opportunistic extension of RRC connected mode
Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to an Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.
Mobile-assisted phase calibration method and system
Disclosed is a method of calibrating phase alignment of signals from multiple transmit antennas on multiple channels during OTA testing of a MIMO DUT, including generating a noisy test signal by adding noise to a signal pattern and transmitting the noisy test signal to the DUT on first and second channels OTA and sweeping a relative phase of the signal pattern, but not the added noise, in the first and second channels, while receiving from the DUT reports of a SNR for a received signal on at least one of the first channel and subsequently on the second channels. The method also includes analyzing variation in the SNR to determine phase alignment of the first and second channels, as received and processed by the DUT and using the determined phase alignment to perform OTA testing of the DUT. The method can also include receiving a RSRP and/or a RSSI.
DEVICE POSITION ACCURACY WITH NETWORK-BASED CROWDSOURCING
Techniques for calculating a location of a position consumer device is disclosed. In one example, a network server may create a fingerprint map from reference data points. Each of the reference data points may include a recorded geo-location of a position source device and signal measurements taken at that recorded geo-location. By initially estimating an initial position of the position consumer device, the network server may apply one or more threshold values to filter reference data points—candidates for interpolation. The network server may then perform an interpolation on one or more pairs of reference data points to find a pair of reference data points that is collinear with the estimated position of the position consumer device. The location of the position consumer device may then be calculated based upon geo-locations of position source devices that are associated with collinear reference data points.
