摘要： Provided are a method and device for acquiring pre-coding information, the method comprising: a network device uses N sub-codebooks to respectively pre-code a pilot frequency group containing K pilot frequencies to obtain N pre-coded pilot frequency groups, wherein the sub-codebooks are subsets of a pre-coding codebook, the pre-coding codebook comprises M pre-coding vectors, and each of the sub-codebooks comprises K pre-coding vectors; the network device sends a pre-coded pilot frequency group to a terminal device on each RB group among W RB groups; and the network device receives pre-coding information fed back by the terminal device with regard to any pre-coded pilot frequency group among W pre-coded pilot frequency groups. By means of the method and device for acquiring pre-coding information, a network device divides a pre-coding codebook into multiple sub-codebooks, the number of pre-coding vectors in each of the sub-codebooks is relatively small, and thus the number of pilot signals sent by the network device on various RB groups is reduced, and pilot frequency overheads on the various RB groups are reduced.

摘要： An apparatus for assigning transmission symbols to a media data stream of information symbols is described, said media data stream encompassing a first partial stream for representing a media content at a basic quality and a second partial stream including additional data for representing the media content along with the first partial stream at an improved quality. The apparatus comprises a first device for assigning first transmission symbols to the information symbols of the first partial stream and a second device for assigning second transmission symbols to the information symbols of the second partial stream, the first transmission symbols being transmissible via a transmission channel having a lower error probability than the transmission channel via which the second transmission symbols can be transmitted.

摘要： The invention relates to a method to determine a transmission mode to be used at a MIMO-transmitter. The determination of an optimum transmission mode is done at the side of a MIMO-receiver. The receiver calculates for each stream of a maximum number of received streams an effective SINR-value for a given first linear dispersion code LDC. The SINR value of each stream is used to select, according to a desired BER target, a suitable modulation alphabet for each stream. A sum-rate is calculated over all streams and a first stream with a minimum effective SINR value is separated and is not considered furthermore. A linear dispersion code LDC with a smaller code rate than the first linear dispersion code LDC is selected and SINR-values for the remaining N-1 streams are calculated. A new sum-rate is obtained accordingly. In case that the new sum rate of the remaining N-1 streams is smaller than the sum rate of N streams, the sum-rate calculation is terminated. In all other cases, the step of separation of a stream with smallest effective SINR, the step of selection of a linear dispersion code LDC with a smaller code rate than the linear dispersion code LDC before and the step of calculation of SINR value for remaining streams are repeated accordingly. The most suitable code rate of the linear dispersion code LDC is selected after the termination and the code rate is reported to the transmitter, together with assigned quantized effective SINR value of each stream, to allow a final decision about a optimum transmission mode at the transmitter.

摘要： A receiver receives and processes a data signal having at least one data signal block. The data signal block has a number of symbols in the time domain and a number of sub-carriers in the frequency domain. The data signal block includes a control region to provide control data to the receiver and a payload region to provide payload data to the receiver. Payload data is allocated to the control region of the data signal block.

摘要： An apparatus comprising a processor unit configured to provide a first high-definition map, a sensor unit configured for providing sensor data representing an environmental condition in a periphery of the apparatus and a receiver unit configured to receive data representing a second high-definition map. The processor unit is configured to fuse the second high-definition map and the sensor data so as to provide the first high-definition map. The apparatus further comprises a transmitter unit configured for transmitting a result of fusing the second high-definition map and the sensor data, and comprises a command generator unit configured to generate a command signal representing a vehicle control command for a vehicle carrying the apparatus based on the first high-definition map.
