Investigation of radio resource scheduling in WLANs coupled with 3G cellular network

Abstract: In this article, based on the overview of network coupling structure between radio access technologies, the concept of joint radio resource management built onto the reference structure is introduced. In order to optimize usage of radio resource and jointly designed from the user perspective, a joint scheduling mechanism allowing traffic to be split over a tightly coupled radio network supported by an adaptive radio multihoming approach is deliberately discussed. With respect to the time-division access scheme in HIPERLAN/2, which is selected as one example of WLAN, algorithms and performance of traffic scheduling in such a radio access technology are given. The required synchronization scheme supporting traffic splitting is also introduced.

Dynamic inter-operator spectrum sharing for UMTS FDD with displaced cellular networks

Abstract: The paper investigates the possibility for competing network operators to cooperate partially without operational information exchange and to share a block of UMTS carriers simultaneously to provide services The performance of spectrum sharing in the worst case for sharing (equal capacity demands) is investigated for the downlink of the UMTS FDD system This work continues from earlier work (Pereirasamy, MK et al, Proc 5th World Wireless Congress, 2004; Proc 15th IEEE Int Symp On Personal Indoor and Mobile Radio Commun - PIMRC, 2004), extending the initial concept to take into account that operators would realistically deploy operating networks composed of separate network equipment and infrastructure The possible gain that is offered through spectrum sharing compared to conventional systems, with only proprietary carriers for operators, is studied for speech type traffic It is found that the relative displacement of cooperating networks has a negative impact on the trunking gain given by the spectrum sharing mechanism Considering only speech service type, a maximum allowed network displacement is given for a spectrum shared environment with the cellular network parameters chosen for this investigation

Method for the transmission of information in a cellular radio communication system with radio sectors

Abstract: The invention relates to a method for the transmission of information in a cellular radio communication system for several user stations, whereby each radio cell (1, 2, 3, 4, 5, 6, 7) in the radio communication system comprises a base station (NB1, NB2, NB3, NB4, NB5, NB6, NB7), by means of which the information is transmitted to user stations using broadcast and/or point to multipoint connections. According to the invention, at least two radio cells (1, 2, 3, 4, 5, 6, 7) in the cellular radio communication system are each divided into n radio sectors (SXa, SXb, SXc with X = 1 to 7) with n ≥ 2 and the information is transmitted in each of the n radio sectors of a radio cell with a temporal displacement. The invention serves to improve the interference situation. The information is advantageously transmitted in n radio sectors without any temporal overlap. Radio sectors can particularly advantageously be collected in a group, alternately comprising the lowest coupling factors with regard to radio transmission and the transmission of information carried out for each group at a different time.

Transmit power control method in a multi-carrier radio system

Abstract: The method involves associating a connection (C) with different frequency carriers (f1-f8), sending signals via the carriers from the transmitter station to a receiver station, dividing the carriers into groups (G1,G2), each with at least two carriers, sending a transmission power control signal (CTR1,..) to the transmitter station for each group and using the control signals to control transmission power for each carrier of the relevant group. Independent claims are also included for the following: (a) a radio system (b) a transmitter station (c) and a receiver station.

Mobile subscriber logging-on method for cellular mobile communications system

Abstract: The logging-on method uses the measured power level, transmission quality or timing-advance for selection of the base station, with the position coordinates of the mobile subscriber station determined for incorporation in the base station selection decision, to prevent selection of a base station which will soon be left by the mobile subscriber. The base station selection decision may be weighted in dependence on the travel velocity and travel direction of the mobile subscriber. The position coordinates of the mobile subscriber station may be provided via a GPS system.

OPTIMIZED Fc VARIANTS AND METHODS FOR THEIR GENERATION

Abstract: The present invention relates to optimized Fc variants, methods for their generation, and antibodies and Fc fusions comprising optimized Fc variants.

Secure data parser method and system

Abstract: A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Optimized Fc Variants

Abstract: The present invention relates to Fc variants having decreased affinity for FcγRIIb, methods for their generation, Fc polypeptides comprising optimized Fc variants, and methods for using optimized Fc variants.

FC variants with altered binding to FCRN

Abstract: The present application relates to optimized IgG immunoglobulin variants, engineering methods for their generation, and their application, particularly for therapeutic purposes.

Exposure apparatus, and device manufacturing method

Abstract: An exposure apparatus for emitting exposure light onto a substrate via a projection optical system and a liquid to expose the substrate includes a supply pipe which supplies the liquid; a recovery pipe which recovers the liquid; a connection pipe which connects the supply pipe and the recovery pipe; and a switching device which switches a flow path of the liquid so that when liquid supply is stopped, the liquid that has flowed into the supply pipe flows to the recovery pipe via the connection pipe. The apparatus may further include a temperature regulation apparatus connected to the supply pipe, which performs temperature regulation of the liquid supplied to the supply pipe, and has a rough temperature regulator which roughly regulates the temperature of the liquid, and a fine temperature regulator which is arranged between the rough temperature regulator and the supply pipe and performs fine regulation of this temperature.
