Patent number: 8891455Abstract: A system and method for synchronous spectrum sharing for a dedicated network in a wireless communication system based on orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signaling is disclosed. The system and method includes detecting a frame of a broadcast waveform and extracting idle spectrum information associated with the dedicated subchannel to the secondary user node. The system allows transmitting data from the secondary user node in unused symbol slots identified in the idle spectrum information thereby making efficient use of unused or idle spectrum. Accordingly, secondary users of the wireless communication system can dynamically form ad-hoc mesh network communications in fixed or mobile scenarios.Type: GrantFiled: May 22, 2007Date of Patent: November 18, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Joseph R.

Patent number: 7773997Abstract: A system and method for controlling Quality of Service (QoS) in a wireless network on a per-user basis. According to the preferred embodiment, each user will have a QoS profile, listing the levels of service he is authorized to receive. The RAN assigns radio and network resources for the user, based on the applications that the user is running and the user's profile. A QoS server in the base station controller manages user QoS. When the base station controller receives a packet data call from a mobile station, the QoS profile and the application type that the mobile station is executing will be used to determine QoS parameters for the user's call.Type: GrantFiled: July 16, 2003Date of Patent: August 10, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: William J.

Patent number: 7379739Abstract: An apparatus and method is disclosed for selecting a handoff target base station in a wireless network. The apparatus comprises a handoff controller within a wireless mobile station that selects an optimal target base station for handoff based on pilot signal strength measurements of at least two candidate base stations and one of: a location of the wireless mobile station, a velocity of the wireless mobile station, and a direction of motion of the wireless mobile station. The present invention uses more than just pilot strength measurements to select an optimal target base station for handoff. Incorporating position location information in the handoff decision causes the handoff decision to be more reliable. This reduces the number of unnecessary handoffs and results in better system performance.Type: GrantFiled: November 14, 2002Date of Patent: May 27, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Purva R.
