摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

摘要： The present disclosure relates to a technique for transmitting modulation symbols on multiple frequency resources. A method aspect of this technique includes applying a Discrete Fourier Transform (DFT) coding per set of modulation symbols of two or more sets of modulation symbols, wherein a first set of modulation symbols from the two or more sets of modulation symbols is transmitted on a set of frequency resources handled by the same power amplifier. Then, Orthogonal Frequency Division Multiplexing (OFDM) modulation is applied to the sets of DFT coded modulation symbols to output a first set of OFDM symbols for transmission on the set of frequency resources, and output another set of OFDM symbols for transmission on at least one additional frequency resource distinct from the set of frequency resources. Power amplification is then applied per set of frequency resources at the power amplifier.

摘要： The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

摘要： A communication unit and a method for communicating at least one signal over a channel of a first channel type and at least one signal over a channel of a second channel type, which is different from the first channel type. The apparatus comprises a timer adapted to schedule a predetermined time period, during which interference due to simultaneous communication of signals over the channel of the first channel type and the channel of the second channel type is anticipated. Also, the apparatus comprises a processing unit adapted to apply, during the predetermined time period, an interference counteracting process for counteracting interference between any signal communicated over the channel of the first channel type and any signal communicated over the channel of the second channel type. The interference counteracting process comprises changing, during the predetermined time period, from a first to a second format for representing information transmitted over the channel of the first channel type, the second format being more robust than the first format.

摘要： The invention relates to a method for scheduling resources for uplink transmissions in a radio access network comprising access points which own pre-assigned resources. The invention also relates to an access point (5-7), a user terminal (1-4) and an access point controller 8. Characteristic features of the invention are that each AP places its resources to the disposition of other APs in the access network, and that an AP (7) transmits a blocking signal (BLOCK R3) if it does not allow a UT (3), which is served by an AP (5) in another cell, to use its resources (R3). A UT that detects a blocking signal from an AP that owns the resources on which the UT is transmitting immediately stops transmission on said resources. The signal quality of a detected blocking signal may be used for setting the transmission power on the resources the UT has borrowed from the AP which transmits the blocking signal. Based on statistics on the APs which transmit blocking signals long-term pre-allocation of resources among the APs is made.
