Title: Inter Node B serving HS-DSCH cell change mechanism in a high speed wireless communication system
Brief Description: This patent application discloses a method for changing the serving high-speed downlink shared channel (HS-DSCH) cell for a user equipment (UE) from a source Node B to a target Node B. It describes a mechanism where the change is initiated and controlled by the radio network controller (RNC) to ensure a seamless handover.
Potential Anticipation of Claims: This reference is highly relevant to the core concepts of US 10,764,803, which deals with managing communication cells during handover. Specifically, it appears to describe a system with a controlling entity (the RNC) that manages the handover process between different base stations (Node Bs) and their respective cells. This could potentially anticipate the novelty of claims in the '803 patent that relate to the designation of primary and non-primary cells and the coordination of data transmission during a handover. For example, claim 1 of the '803 patent, which describes a WTRU receiving configuration information for a primary and non-primary cell and then receiving a message on the primary cell indicating a downlink transmission from the non-primary cell, appears to be taught by the concepts in this prior art. The RNC in US20030147370A1 performs a similar role to the "wireless network node" in the '803 patent's claims.

Title: Switching from dedicated to common channels when radio resources are controlled by drift radio network
Brief Description: This patent describes a method for switching a mobile station's connection from a dedicated channel to a common channel in a cellular system where radio resources are controlled by a drift radio network controller. This is relevant in situations like soft handover where a mobile station is in communication with multiple base stations.
Potential Anticipation of Claims: The teachings of this patent could be seen as anticipating certain aspects of the claims in US 10,764,803. The concept of managing different types of channels (dedicated vs. common) and coordinating communication across multiple cells during a handover scenario is central to both. The claims in the '803 patent that deal with receiving messages on a primary cell that provide instructions for receiving transmissions on a non-primary cell could be interpreted as a specific implementation of the broader channel switching and resource management concepts described in US 6,829,482 B2. The '482 patent discusses the role of a controlling network entity in managing these transitions, which is analogous to the function of the "wireless network node" in the '803 patent.
