Patent number: 9107136Abstract: Methods and apparatus for controlling access of a mobile device to a femtocell base station in a communications network are described. The method determines whether to allow access of the mobile device to the femtocell base station based on the femtocell-mobile device path loss for transmissions between the mobile device and the femtocell base station. Access may be allowed if the femtocell-mobile device pathloss is lower than a threshold amount. Additionally or alternatively access may be allowed only if the femtocell-mobile device pathloss is lower than the macrocell-mobile device pathloss for transmissions between the mobile device and a macrocell base station. The method is particularly applicable for hybrid access mode femtocells and additional conditions may be applied regarding the number of mobile device that are not part of the subscriber group that can access the femtocell. The method may be implemented by the femtocell, the macrocell or by any other suitable network device.Type: GrantFiled: February 15, 2013Date of Patent: August 11, 2015Assignee: Intel CorporationInventors: Nick Whinnett, Fiona Somerville

Publication number: 20070123267Abstract: A cellular communication system includes first and second base stations and a user equipment. A Radio Network Controller controls a handover of the user equipment between the base stations by either forwarding data of the communication to both the first and second base stations or to only one of the first and second base stations dependent on a Quality of Service (QoS) characteristic of the communication of the user equipment. The QoS characteristic can specifically be an indication of a delay constraint for the communication service such as an indication of whether the service is a real-time service or a non-real time service.Type: ApplicationFiled: November 29, 2005Publication date: May 31, 2007Inventors: Nick Whinnett, Amitava Ghosh, Weimin Xiao

Publication number: 20060135193Abstract: A method (400) and apparatus (501) provide for rapid power control based on a quality related value, e.g. channel quality indicator (CQI) value. A transmit power level can be derived from a CQI value received according to a time period, e.g. corresponding to 500 Hz. A first predicted value can be predicted based on the CQI value, at a first time within the time period and a power adjustment value can be determined based on the CQI value as well as the first predicted value at a rate that exceeds the rate of receiving the CQI values. Note that other predicted values for or corresponding to the CQI value can be predicted at other times within the time period and that power adjustment values can be determined through interpolation between predicted values for any time within the period.Type: ApplicationFiled: December 20, 2004Publication date: June 22, 2006Inventors: Rapeepat Ratasuk, Amitava Ghosh, Fan Wang, Weimin Xiao, Nick Whinnett

Publication number: 20060105798Abstract: Various embodiments are described to address the need for an apparatus and method of outer-loop power control for enhanced uplink communications that address some of the outstanding problems in the prior art. Generally expressed, a base site (131), while a first uplink channel is inactive, monitors packet retransmissions to generate an uplink quality indicator. Here, packet retransmissions refers to the number of packet retransmissions used by a remote unit (101) to send packets to a base transceiver station (111) via at least one other uplink channel. Also, while the first uplink channel is inactive, the base site adjusts a signal-to-interference ratio (SIR) target for the first uplink channel based on the uplink quality indicator. Then, when the first uplink channel becomes active, the base site begins power controlling the first uplink channel using the SIR target.Type: ApplicationFiled: November 8, 2005Publication date: May 18, 2006Inventors: Amitava Ghosh, Rapeepat Ratasuk, Nick Whinnett

Publication number: 20060099985Abstract: A base station (101) of a cellular communication system (100) comprises a receiver (105) and a channel quality processor (111) which receive channel quality indications from a communication unit (103). The base station (101) further comprises a transmitter (107) for transmitting signals to the communication unit (103). A first power control processor (115) controls the transmit power in response to a first power control mode of operation and a second power control processor (117) controls the transmit power in response to the second power control mode of operation. A rate processor (113) determines a rate of change indication for the channel quality indications and a selector (119) selects between the first power control mode and the second power control mode in response to the rate of change indication. The power control mode of operation may be modified to suit the current channel variations of the communication channel.Type: ApplicationFiled: November 9, 2004Publication date: May 11, 2006Inventors: Nick Whinnett, Amitava Ghosh, Rapeepat Ratasuk, Weimin Xiao
