摘要： A method and base station for forming an OFDM signal from a baseband signal includes a partitioning unit configured to partition a block of baseband signal samples into sub-blocks. A sub-carrier mapper maps the sub-blocks onto adjacent sub-carrier blocks of an OFDM multi-carrier to form corresponding unprefixed OFDM symbols. A cyclic prefix adder adds a cyclic prefix to each mapped sub-block to form prefixed OFDM symbols. Phase compensations force the unprefixed OFDM symbol part of all subsequently up-converted prefixed OFDM symbols to start at the same phase. Up-converters up-convert the phase compensated prefixed OFDM symbols to respective radio frequency bands having center frequencies and bandwidths that preserve the OFDM multi-carrier structure. A combiner combines the up-converted phase compensated prefixed OFDM symbols into an OFDM signal.

摘要： A transmitting node uses different reference signal sequences for different types of enhanced control channels. An example method begins with generating (1410) a first reference signal sequence, from a first initialization value, and generating (1420) a second reference signal sequence, from a second initialization value. These reference signal sequences are associated with two corresponding enhanced control transmissions. A first enhanced control channel and reference symbols taken from the first reference signal sequence are transmitted (1430), using first time-frequency resources and a first set of transmission points or a first set of antenna ports or both, and a second enhanced control channel and reference symbols taken from the second reference signal sequence are also transmitted (1440), using a differing second set of transmission points and/or a differing second set of antenna ports and/or a differing second set of time-frequency resources, in the same subframe or group of subframes.

摘要： A communication system includes a transmitting communication device (310) and a receiving communication device (320). The transmitting communication device (310) determines a control element, e.g., a control element of a Media Access Control protocol, associated with one of the carriers and provides the control element with an identifier specifying the carrier the control element is associated with. The transmitting communication device (310) sends the control element with the identifier on one of the carriers to the receiving communication device (320). The receiving communication device (320) receives the control element and determines, from the identifier received with the control element, the carrier the control element is associated with. Further, the receiving communication device (320) determines, on the basis of parameters indicated by the control element, a data transmission property of the carrier the control element is associated with.

摘要： A coupler head for a coupling arrangement is shown, which coupler head includes a coupler head housing (6) extending in a longitudinal direction from a first end (6a), attachable to a drawbar, to a second end (6b), which is arranged to carry a coupling interface between coupled rail vehicles, which coupler head housing houses mechanical coupling components (8,9) effective for automatic coupling to the corresponding components of a connecting coupling arrangement. The coupler head is characterized in that the coupler head housing has at least one notch (11, 11′) for a predetermined and primarily axial compression thereof with absorption of energy from a deforming compressive force that is applied to the coupler head in the longitudinal direction thereof. The coupler head has preferably at least one notch (11, 11′) for a predetermined folding of the coupler head housing.

摘要： Methods, for use in a communications system, for transmitting information that applies a method for channel coding the CQI/PMI information, wherein a turbo coding method is applied when the size of the CQI/PMI information is above a first threshold value. The methods further include setting, based on the method applied for the channel coding, an offset value indicative of the difference in code rate between the code rate of the CQI/PMI information and the assigned code rate of the UL-SCH data information on the PUSCH. The methods also include determining, based on the offset value, the number of coded bits to be used for transmission of the CQI/PMI information, and transmitting the CQI/PMI information to a radio access network node on resources assigned based on the determined number of coded bits.
