Abstract: The disclosed embodiments are directed toward improvements in dynamic spectrum sharing (DSS) between cellular network technologies. In one embodiment, a method is disclosed comprising initiating scheduling for a resource in a slot and determining a neighboring base station associated with user equipment (UE). The method then determines a type of interference associated with the neighboring base station and the slot and identifies an outer loop link adaptation (OLLA) value associated with the type of interference. An effective data rate is calculated based on the OLLA value and the method completes scheduling using the effective data rate.

Abstract: The present invention provides a method of locating a mobile unit. The method may include storing, at a location outside of a mobile unit, information indicative of a last known location of the mobile unit and the associated time stamp. The method may also include transmitting, from a mobile unit, information indicative of the last known location of the mobile unit. The last known location is determined using global positioning system satellite signals.

Abstract: The per sector or per cell downlink capacity in a spread spectrum wireless network is determined using a single test mobile that is operating within a background of simulated co-channel interference being broadcast in each sector by all cell sites in the network whose capacity is of interest. From all sectors, an Orthogonal Channel Noise Simulator (OCNS) generates a multiple number of calibrated test signals, which are aggregated and broadcast downlink, where each transmitted test signal simulates the downlink power transmitted to a live mobile. Each component test signal in the aggregated OCNS output transmitted in each sector is a sample of a stochastic process with a set mean and standard deviation that are determined from the mean and standard deviation of the power of a real signal transmitted downlink to the test mobile as it is moved around the network's coverage area.

Abstract: To take advantage of hierarchical cell layers, an inter-layer handoff system determines a cell layer for servicing a wireless unit at least as a function of the duration that the wireless unit is in a cell or set of cells of a cell layer. For example, as a function of the duration that the wireless unit is in the cell or set of cells for a first cell layer, a determination is made as to whether the wireless unit should be serviced by a cell or set of cells of a second cell layer. As such, wireless units moving at higher speeds which will be handed off frequently in a smaller cell layer(s) are serviced by a larger cell layer(s). Thus, the hierarchical cellular communications system can have the increased capacity provided by the smaller cell layer(s) while reducing the number of handoffs which would occur of the faster moving wireless units in the smaller cell layer(s).
