A method to control cell selection and/or re-selection in a communication system comprising a plurality of cells with which terminal devices may communicate, the method including the steps of: determining that a terminal device is to start a session for a certain service, the service using a reception frequency; based on that determination, changing at least one cell selection and/or re-selection parameter in respect of the terminal device with the effect that a subsequent cell selection and/or re-selection performed by the device would favor cells that use the reception frequency used in the service session over other cells.

Frequency layer convergence method for MBMS

A method, apparatus, system, network element, and software product are used to provide a traffic signal, such as a voice over internet protocol (VoIP) signal, via high speed packet access. The traffic signal is prepared and provided via a high speed transmission, and a control signal is gated to produce a discontinuous transmission. This reduces interference, and therefore increases traffic capacity.

Method, system, apparatus and software product for combination of uplink dedicated physical control channel gating and enhanced uplink dedicated channel to improve capacity

A communication method and system are provided that include providing synchronization information about a co-sited downlink carrier. This information may be transmitted to from a base station to a mobile device. The mobile device may receive this information and perform handover or measurements based on the received synchronization information.

Method and apparatus for utilizing synchronization information

Methods, computer-readable media, and devices are provided that support antenna diversity in a communication system. In an exemplary method, a signal is received from a first device at a second device in a first channel. A determination is made concerning whether or not transmit diversity is applied to the first channel. If transmit diversity is applied to the first channel; a first channel estimate is determined based on a first pilot signal received from the first device and a second channel estimate is determined based on a second pilot signal received from the first device. The received signal is decoded based on the first channel estimate and the second channel estimate.

Method to enable open loop antenna transmit diversity on channels having dedicated pilots

The use of the STTD is enabled in a network so that the common channels (CPICH etc.) do not need to be transmitted using transmit diversity, but the STTD can be enabled only for channels having dedicated pilots and which are intended for the UEs supporting this functionality. Other UEs not supporting transmit diversity can use the common channels as usual. In normal transmit diversity operation the UE will use the CPICH transmitted from both antennas as a phase reference. In the proposed method some of the common channels including CPICH are transmitted without transmit diversity even though the STTD is used on channels having dedicated pilots and which are intended for the UEs supporting this functionality.

This invention addresses the problem of latency of response regarding information relying on an IMEISV from a CN. This is possible by defining the early RRC connection bits' indication to determine the supported signalling schemes and providing the IMEISV information from the terminal to the network. After this point the CN is able providing this mapping information to the radio access network before actual radio links are utilized. The idea here is for early RRC message information to be used for indicating what version of bitmap correction terminal capabilities refers to and what procedures can be utilized while waiting for this bit map information from the CN. Using this approach the length of the early RRC message can be kept short, the content of corrections can be well defined saving signalling bits, and the concern of a fast available indication on the connection set-up phase can still be addressed.

Method for controlling terminal fault corrections in cellular system

A method is described for providing a discontinuous radio link for user equipment in a telecommunication network in a physical radio transmission layer while receiving packets during a packet service mode (i.e. maintaining the logical connection in higher protocol layers). The user equipment enters into a discontinuous reception mode receiving either a) two or more slots of each radio frame, or b) one or more frames; and powers down its receiver circuitry for either a) the remaining slots of the radio frame or b) one or more predefined periods, signaled by the telecommunication network. The two or more slots may be consecutive or non-consecutive slots in the radio frame.

Method and apparatus for discontinuous reception scheme and power saving mode for user equipment in packet access mode

A method and device for avoiding adjacent channel interference and reducing disconnections caused thereby, during communication between a mobile device and a base station in a wireless telecommunications network. The mobile device measures the strength of a received signal before the signal enters one or more selected filters, and compares the strength of the signal after the filtering, in order to estimate a power ratio of the adjacent channel interference to communication channel power. If the power ratio is greater than a threshold, then a handover is requested to an alternative communication channel available between the mobile device and either the base station or another base station.

Measurement method and device for activating interfrequency handover in a wireless telecommunication network

The invention pertains in general to the testing of the operation of radio and other data transmission apparatus. In particular the invention pertains to the testing of the operation of a digital radio apparatus on the basis of error statistics. In order to test functions relating to data transmission, a simulation system produces a pseudorandom bit sequence or some other test sequence which is packed into downlink frames and sent to the data transmission apparatus tested. In accordance with the invention, a known number of errors are generated in the test sequence. As the data transmission apparatus tested compares the received test sequence to the sequence it has produced, it detects the errors in the received sequence and compiles various error statistics, e.g., in the form of bit error ratio (BER) or frame erasure ratio (FER). An uplink connection is used to send these statistical data to the simulation system which examines whether the information produced by the data transmission apparatus tested matches the simulation system's information about the erroneousness of the sequence sent downlink.

Method and apparatus for measuring and optimising the quality of data transmission

A method for a mobile station and a base station to which the mobile is being handed over, and corresponding apparatuses for use by the mobile and the base station. The method for use by the mobile station is for determining whether dynamic configurations are in use by the base station to which the mobile is being handed over, and the method for use by the base station is for determining whether to use a dynamic configuration (if the base station uses dynamic configurations) or to switch to a static preconfiguration in communicating with the mobile. The base station to which the mobile is being handed over is of one wireless communication system (such as the UTRA wireless communication system) and the base station doing the handing over is of another type (such as GSM). Both base stations are assumed to broadcast control signals on a respective broadcast control channel.
