摘要： Transmitter(s) (34), radio base station nodes (38) comprising transmitter(s), and methods of operating transmitter(s)/radio base station(s) involve handling discontinuous transmission indication bits, particularly when transmitting using a 16 QAM signal point constellation having an I-branch and a Q-branch (for a quadruple of bits comprising two I-branch bits, i1 and i2, and two Q-branch bits q1 and q2). The transmitter(s) (34) and the radio base station nodes (28) comprised thereof are operated to perform a Multimedia Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission wherein the MBSFN transmission comprises mapping data to a Secondary Common Control Physical Channel (S-CCPCH). For the Secondary Common Control Physical Channel (S-CCPCH) the methods include operating a 16 Quadrature Amplitude Modulation (QAM) transmitter (34) according to a predetermined strategy. The predetermined strategy is configured whereby one or more discontinuous transmission indication bits input to the transmitter (34) result in unambiguous determination of output values from an Inphase (I) output and a Quadrature (Q) output.

摘要： A pilot channel signal for time-division multiplexing with one or more traffic channel signals in a broadcast/multi-cast signal and for code-division multiplexing with a continuously transmitted pilot channel signal is described. In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames.

摘要： The present invention is directed toward an automatic frequency control system for compensating for frequency offset of received data signals in a radio frequency communication system. A reference sample index for the data to be compensated is first determined as a function of the transmission channel and known training data. A scaled phase error estimate is calculated along with a time-varying filter parameter. From the scaled phase error estimate and the filter parameter, a frequency offset estimate and a phase drift estimate are calculated. The system proceeds through the time-indexed, received data signals until the entire received batch of data signals has been processed, and the corresponding compensated soft data has been output.

摘要： Inter-cell interference coordination across layers of a communication network can be implemented by configuring a cell to transmit one or more downlink transmission resources having variably reduced transmission activity. A transmitting node, such as a macro cell, can transmit transmission resources, such as resource elements, resource blocks, subframes, and frames, having reduced transmission activity at varying predictable times according to a selected cell activity pattern. A receiving node, such as a user equipment, can decide to make received signal measurements according to the cell activity pattern.

摘要： Physical downlink channels PPHY1, PHY2 are summed in a summation unit 10. The output of summation unit 10 is forwarded to another summation unit 12, where it is combined with the primary and secondary synchronization channels P-SCH, S-SCH. The secondary synchronization channel S-SCH is formed as in WCDMA. The primary synchronization channel P-SCH is formed by connecting a switch SW either to a code generator 14 generating the conventional code PSCWCDMA or a code generator 18 generating the code PSCNEW. The selection is controlled by a PSC controller 18. This controller can be adapted to produce a P-SCH in accordance with one of several formats. PSCNEW has the properties that it is a hierarchical Golay sequence constructed by a plurality of constituent sequences with at least one of the constituent sequences being the Golay sequence, and that it is orthogonal to the primary and secondary synchronization codes used in non-MBSFN capable WCDMA.

摘要： The present invention relates to methods and arrangements for assisting a User Equipment (UE) to determine transmit power to be used on a first uplink component carrier y, wherein the base station is configured to communicate with the UE over a plurality of uplink and downlink component carriers x,y. The UE is aware of path loss parameters associated with a second downlink component carrier x. The method in a base station comprises determining cell specific path loss parameters associated with the component carriers of the base station. The cell specific path loss parameters at least comprises path loss parameters associated with the first uplink component carrier y and a second uplink component carrier x which is paired to the second downlink component carrier x, wherein the second uplink component carrier and second downlink component carrier are within one frequency band. The method comprises the further steps of calculating a pathloss offset, deltaPL(y,x), for the first uplink component carrier y, wherein the pathloss offset deltaPL(y,x) is the pathloss power offset for the first uplink component carrier y with respect to the second uplink component carrier x, and sending the calculated pathloss offset, deltaPL(y,x) to the UE.

摘要： The present invention provides, inter alia, a method of operation of a radio base station in a wireless telecommunications system, in which system information is transmitted on a broadcast control channel. The method comprises the steps of transmitting the broadcast control channel continuously on a first carrier; and also transmitting the broadcast control channel non-continuously and periodically at regular intervals. This prevents or at least minimizes, for example, MBMS data loss when a UE with a single receiver listens to a dedicated MBMS carrier.
