Patent number: 8830965Abstract: This radio communication method is used to perform spatial multiplexing communication between cells in the overlap cell environment. In the MU-MIMO overlap cell environment, when a null is formed between a radio base station and a radio terminal station belonging to different cells, a first set of a “call signal” and a “response signal” is used to perform mutual detection with the radio base station and the radio terminal station belonging to different cells, and then a null is formed so as not to cause interference of radio waves between the radio base station and the radio terminal station belonging to different cells. At this time, the addresses of the radio base station and the radio terminal station are used to discriminate whether the radio base station and the radio terminal station belong to the same cell or different cells.Type: GrantFiled: July 8, 2010Date of Patent: September 9, 2014Assignee: Nippon Telegraph and Telephone CorporationInventors: Tomoki Murakami, Takeo Ichikawa, Riichi Kudo, Yasushi Takatori, Masato Mizoguchi, Takefumi Hiraguri, Kentaro Nishimori

Patent number: 8825044Abstract: A wireless communication device (WCD) may be able to acquire wireless service from preferred wireless coverage areas that are managed by the WCD's service provider. In some cases, the WCD may instead use wireless service from non-preferred wireless coverage areas of the service provider's roaming partners. In order to save roaming fees, the service provider's RAN may determine when the WCD is likely to roam to a non-preferred wireless coverage area. In response to this determination, the RAN may transmit a redirect message to the WCD, causing the WCD to switch from one preferred wireless coverage area to another preferred wireless coverage area. In some situations, the RAN may transmit such a redirect message because the WCD has reported that it has a low remaining battery life.Type: GrantFiled: March 10, 2011Date of Patent: September 2, 2014Assignee: Sprint Spectrum L.P.Inventors: Siddharth S.

Patent number: 8805381Abstract: Triggering device scanning and efficient femtocell detection in areas dominated by macro cells can be facilitated. In particular, a jamming component generates a small and measured amount of interference to user equipment or user equipments (UEs) camping on nearby macro carriers. Moreover, the power utilized to introduce the interference can be enough to cause macro signal quality around the femtocell access point (AP) to fall below a scan trigger level. The UE(s) can detect the macro signal quality decline below the scan trigger level and scan other frequency bands, including the femtocell, on which to camp. Additionally, femto pilot gating can be performed, such that the jamming component can scan the radio environment surrounding the femto AP during an off state, to determine information that facilitates jamming of a macro pilot.Type: GrantFiled: July 29, 2013Date of Patent: August 12, 2014Assignee: AT&T Mobility II LLCInventors: Arthur Brisebois, Giuseppe De Rosa

Patent number: 8744362Abstract: A cellular radio communication system includes a first mobile terminal, a base station that performs radio communication with first mobile terminals, a second mobile terminal, and a second base station that performs radio communication with second mobile terminals. In the downlink communication, the base station selects a high data rate mode when the radio interference from the base station to the second mobile terminals that are located close to an edge of a communication area of the second base station is small. The base station selects an interference mitigation mode in the downlink communication when the radio interference from the base station to the second mobile terminals that are located close to the edge of the communication area of the second base station is large. Thus, inter-cell interference control can be performed in collaboration with base stations in the radio communication system without having communication interface between the base stations.Type: GrantFiled: June 2, 2011Date of Patent: June 3, 2014Assignee: Hitachi, Ltd.Inventors: Takuji Kawahatsu, Rintaro Katayama, Satoshi Tamaki, Tomonori Yamamoto

Patent number: 8744452Abstract: A basestation for a cellular communications network is intended to provide coverage over a small area, which may be within an area that already has cellular coverage from one or more existing basestations. The basestation is therefore able to detect signals transmitted from the other basestations, in order to make measurements of the radio environment. In particular, the basestation may be able to receive signals periodically on the system downlink frequencies.Type: GrantFiled: May 8, 2007Date of Patent: June 3, 2014Assignee: Ubiquisys LimitedInventors: Alan Carter, Stephen Whittaker, Aminu Wada Maida

Patent number: 8744451Abstract: Handover of a call to a dual-mode phone from cellular to Wi-Fi. When handing over a call mediated by a mobility controller to a dual-mode phone and switching the call from a cellular to a Wi-Fi call, the mobility controller initiates a Wi-Fi connection to the dual mode phone. When the Wi-Fi connection is established, and with the cellular connection through the mobility controller still in place, the mobility controller starts a timer with a predetermined value and the dual-mode phone initiates release of the cellular connection. When the timer expires, the mobility controller switches the call from the cellular connection to the Wi-Fi connection.Type: GrantFiled: December 12, 2007Date of Patent: June 3, 2014Assignee: Aruba Networks, Inc.Inventor: Rajneesh Bajpai
