摘要： A radio node (12, 14) is configured to transmit or receive reference symbols (18) of a reference signal (16) on respective radio resources, including first and second sets (S1, S2) of radio resources that differ in at least one radio resource. The reference signal (16) may be for instance a tracking reference signal (16) configured for time or frequency tracking. The first set (S1) of radio resources includes a first pair of radio resources that are separated from one another in a radio resource domain by a first separation distance (D1). The second set (S2) of radio resources includes a second pair of radio resources that are separated from one another in the radio resource domain by a second separation distance (D2). The radio resource domain may be a time domain or a frequency domain. In one or more embodiments, the second separation distance (D2) is at least twice as large as the first separation distance (D1).

摘要： P72243 WO1 34 ABSTRACT A radio node (14) is configured to perform frequency offset estimation. The radio node (14) in this regard receives a first set (22-1) of reference symbols of a reference signal during respective time resources, and determines a first frequency offset estimate (26-1) using the first set (22-1) of reference symbols. The radio node (14) also receives a second set (22-2) of 5 reference symbols of the reference signal during respective time resources, e.g., using the same local oscillator frequency for down conversion as with the first set (22-1). The radio node (14) further determines, based on the first frequency offset estimate (26-1), a second frequency offset estimate (26-2) using the second set (22-2) of reference symbols. In some embodiments, the radio node (14) determines a third frequency offset estimate as a sum of the first and 10 second frequency offset estimates, and tunes a local oscillator frequency, or performs frequency offset compensation, based on the third frequency offset estimate.

摘要： The present invention relates to methods and arrangements for distributing UE transmit power between multiple UL component carriers, e.g. in situations where the UL component carriers reside in different bands or where data with different importance are scheduled onto the different component carriers and between the PUSCH and the PUCCH when those channels are transmitted simultaneou sly. To be able to control the distribution of the available transmit power of a UE between multiple UL component carriers and/or between PUCCH and PUSCH, individual power weighting factors to be used by the UE are configured by the eNB according to embodiments of the present invention. The power weighting factors are signaled to the UE accordingly and used by the UE to weight PUCCH and PUSCH and/ or different component carriers.

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： Physical downlink channels PPHYl, 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 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.
