The present invention relates to a method for monitoring network performance in a wireless communication network comprising multiple cells that communicate with wireless devices. Each cell provides coverage in a geographical area and the wireless communication network has a cell coverage plan with a calculated performance. The method comprising: a) retrieving geospatially located measurements from wireless devices; b) connecting each geospatially located measurement to a cell; c) arranging measurements into at least one cluster per cell; d) identifying deviations from the cell coverage plan; and e) initiating actions to reduce deviations.

In some aspects, a method of wireless communication by a user equipment (UE) includes receiving, by the UE on a component carrier (CC), a downlink (DL) control information (DCI) that triggers transmission, by the UE on another CC, of an uplink (UL) reference signal (RS) for positioning. The method additionally includes transmitting, by the UE in response to the DCI, the UL RS for positioning on the other CC. In other aspects, a method of wireless communication by a base station includes transmitting, by the base station to a UE on a CC, a DCI that triggers transmission, by the UE on another CC, of an UL RS for positioning. The method additionally includes receiving, by the base station from the UE in response to the DCI, the UL RS for positioning on the other CC.

A user equipment (UE) periodically obtains its location using UE based Observed Time Difference of Arrival (OTDOA). The location is based on Reference Signal Time Differences (RSTDs) measured by the UE for downlink (DL) signals transmitted by each of a plurality of base stations, and the most current Real Time Differences (RTDs) for pairs of base stations. The RTDs may be determined by the UE using the RSTD measurements and Round Trip Time (RTT) measurements determined by a network entity or by the UE. The RTDs may be determined less frequently than the UE location to reduce network and UE load. Location of the UE may be improved based on testing a rate of change for each of the RTDs. The RTD determination may be improved using measurements from a plurality of UEs.

An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.

Disclosed are various embodiments for managing location-based service zones being monitored by a client device. The location-based service zones within a geographic region can be organized in location-based service zone clusters. In response to receiving an active zone from a computing device, a client device can begin monitoring the geographic parameters for the top-level location-based service zone clusters. When the client device detects an entry into a particular location-based service zone cluster, the client device stops monitoring the top-level location-based service zone clusters and begins monitoring the location-based service zones that are within the particular location-based service zone cluster.

Wireless communication equipment (12, 16) detects a targeted signature over time in a Doppler spread and/or an angular spread associated with a wireless communication device (12). Based on detecting the targeted signature, the wireless communication equipment (12, 16) detects a transition (14) by the wireless communication device (12) between an indoor environment (8) and an outdoor environment (6). In some embodiments, based on detecting the transition (14), the wireless communication equipment (12, 16) adapts one or more communication parameters, adjusts resources allocated to the wireless communication device (12), and/or initiates handover of the wireless communication device (12).
