Abstract: Methods, apparatus, processors and computer readable medium for inter-radio access technology (RAT) handover are provided that incorporate a soft-decision making process. By implementing configurable functions, soft-decision making allows for handover measurement limits to fall within a prescribed acceptable range and for the totality of the handover measurements to be used in making a final decision on inter-RAT handover. Thus, the currently described aspects provide for more flexible handover decision-making and better utilization of network radio resources. Further, in some instances, the currently described aspects may provide for the weighting of handover measurements, thereby allowing network administrators to place more or less emphasis on a selected handover measurement and, thus, better manage the handover process.

Abstract: A system and method are provided for mobile Internet Protocol (IP) addressing, in a multi-mode wireless communications access terminal (AT). The method provides an AT with an IP address (ATA), and a care-of-address (CoA) in each of a plurality of networks. In one aspect, the AT selects a first network for transmission, from the plurality of networks. The AT sends an IP packet to a correspondent node (CN) via a first mobile node (MN) external device. Regardless of the network selected, the AT is able to use the ATA as a source address. Sending the IP packet to the CN may include creating a tunnel between the first MN and the HA. The IP packet is sent to the HA using the first CoA as a tunnel source address, and the HA sends the IP packet to the CN using the ATA as the source address.

Abstract: Techniques for performing equalization of multiple signals received by a terminal in soft handoff with multiple base stations. The received signal at the terminal is conditioned and digitized to provide a stream of received samples, which is then equalized/filtered with multiple sets of coefficients to provide multiple streams of transmit chip estimates. One set of coefficients is provided for each base station and is used to provide a corresponding stream of transmit chip estimates. The multiple streams of transmit chip estimates are further processed to provide multiple streams of data symbol estimates, one stream of data symbol estimates for each base station. The multiple streams of data symbol estimates are then scaled with multiple scaling factors and combined to provide a stream of combined data symbol estimates. The processing for the multiple base stations may be performed by a single hardware unit in a time division multiplexed manner.

Abstract: A timing estimation system and methodology are provided. In particular, a first pilot is employed in conjunction with three acquisition stages. In the first stage, an attempt is made to observe the leading edge of the correlation curve associated with the first pilot symbol. In the second stage, a determination is made to confirm a leading edge was detected in the first stage by attempting to observe a trailing edge of the correlation curve. Furthermore, during this second stage, a frequency loop is updated to account for frequency offset. The third stage is for observing the trailing edge of the curve if it was not already observed in stage two. Upon detection of receipt of the first pilot, a second pilot can subsequently be employed to acquire fine symbol timing.
