CPC Class H04W

Detecting and mitigating the effects of interference in a positioning system. A received signal is divided into a plurality of receive signal time/frequency (RSTF) values. A plurality of threshold values are determined based on expected energy values for the received signal. In one implementation, if a predetermined number of the RSTF values are above the threshold, the received signal is determined to be corrupt.

Systems and methods for determining a location of one or more user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of at least one UE among the one or more UE. Embodiments include multichannel synchronization with a standard deviation of less than or equal 10 ns. Embodiments can include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.

A mobile station (MS), a base station subsystem (BSS), and various methods are described herein that enable the MS to receive acknowledgement of an access attempt for performing a multilateration timing advance (MTA) procedure using an Access Burst method without also being assigned resources.
