  • Patent number: 9510356
    Abstract: There is proposed a mechanism for controlling communications conducted in multiple frequency bands, in particular for controlling interference caused by intermodulation distortion. When the UE obtains information that an interference caused by an intermodulation distortion produced by a set of first communications performed on at least a first and a second frequency and a second communication performed on a third frequency is present, an indication to the eNB for indicating that an interference situation caused by intermodulation distortion exists. The eNB receiving this indication is enabled to acquire parameters related to the interference situation caused by the intermodulation distortion, and to control, on the basis of the acquired parameters, a communication with the UE by changing communication properties for reducing the interference caused by intermodulation distortion.

  • Publication number: 20150282047
    Abstract: In a multi-RAT user equipment autonomous denials are used to stop LTE transmission to free frames or subframes for the transmission of e.g Bluetooth or WLAN signals. The use of the autonomous denials is limited per defined time period. The start of this time window may not be synchronised between UE and eNB. To avoid any synchronisation problems, a system frame number associated with the network entity is used as the basis for generating an indicator for the start of the time period. The indicator is then transmitted to the user equipment, which is adapted to respond to receipt of the indicator by configuring the user equipment to perform no more than a predetermined number of autonomous denials during the time period. The number of unsuccessful transmissions during the time period is then monitored by the network entity, and resource usage within the wireless communications network is selectively adapted on the basis of the monitoring.

  • Patent number: 8837321
    Abstract: A network sends downlink a neighbor frequency list for redirection (with at least one neighbor frequency) for measurement, for example event-triggered measurement. For each frequency in the list which a user equipment UE finds to satisfy one or more criteria, for example event-triggering criteria, the idle-state or semi-idle-state UE then takes a measurement of the neighbor frequency and checks whether the measurement satisfies reporting criteria. The UE sends to its serving cell an indication of the neighbor frequency or frequencies whose measurement meets the reporting criteria, without reporting the measurement, such as in a RRC Connection Request message. The serving cell then redirects the UE to establish a connection on a target frequency selected from the indicated neighbor frequencies, and this redirect may be in a RRC Connection Reject message.

  • Patent number: 8385361
    Abstract: The present invention relates to a method and system for performing a multicast transmission in a cellular network, wherein an identification information, which indicates terminal devices and/or areas in which authorized terminal devices are assumed to be located, is transmitted from a core network (100) to a radio access network of the cellular network by using a control information transmission protocol. Then, a signalling connection of a control and user data transmission protocol is establishing based on said identification information and used for transmitting multicast related data and corresponding control information between the core network (100) and the radio access network. Thereby, already defined protocol layers can be used for implementing multicast transmission, while modifications are minimized.

  • Patent number: 7869414
    Abstract: The area of the invention belongs to the transport technologies in UTRAN. This invention concerns a method for multiplexing a data stream onto a transport bearer between an originating network node and a receiving network node in a telecommunications network. This is done in order to ensure the effective usage of transport resources over the two interfaces, i.e. Iub/Iur. To accomplish this the RNC and/or Node B/RNC should check if the there already exists a transport bearer, which can be utilized for HS-DSCH transport over Iub/Iur interface. Because of this a transport bearer identification code or transport bearer id is needed to identify this bearer between RNC and Node B/RNC.

  • Patent number: RE43108
    Abstract: In packet data transmission method, a packet data connection is indicated with a connection identifier and the destination of the packet data connection is indicated with a destination identifier. A destination identifier is involved in the initialization of a transmission queue, at least one connection identifier is related to each transmission queue, and a set of proper connection identifiers is the union of the connection identifiers related to the initialized transmission queues. A data packet having a proper connection identifier is placed (504, 505) to the corresponding transmission queue. The method is characterized in that the initialization of a new transmission queue is triggered (506, 508) by a data packet not having a proper connection identifier and having a destination identifier and after a successful initialization of a new transmission queue the data packet that triggered the initialization is placed (509) to the new transmission queue.
