摘要： In an LTE network (10) employing carrier aggregation, a cross-scheduled UE (16) may initiate a random access procedure on a secondary component carrier (SCC) by transmitting a random preamble on the UL SCC PRACH. Contrary to normal cross-scheduling procedure—in which the UE (16) reads PDCCH on PCC and PDSCH on SCC using a provisioned pdsch-Start parameter—the UE (16) reads PCFICH directly on the DL SCC to obtain the CFI. The UE (16) uses the DL SCC CFI to access the PDSCH to read a message from the network (10) specifying a timing advance value for the UE (16) to use on UL SCC. For other DL SCC traffic, the UE (16) reads the DL PCC PDCCH and uses the pdsch-Start parameter to locate PDSCH on SCC.

摘要： A method for determining a random access transmission power setting of a first communication device in a communications network includes receiving, at a first communication device, data from a second communication device indicating a random access reception power. The method also includes determining a desired random access reception power of the second communication device based on the received data and a parameter of random access configuration that influences a detection performance of the random access at the second communication device and determining a random access transmission power to use based on the desired random access reception power. The method additionally includes setting a random access transmission power setting of the first communication device in accordance with the determined random access transmission power.

摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (22) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.

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： Methods and apparatus for generating, transmitting, and processing error control information in a wireless communication system are disclosed. The error control information is designed so that the probability of a NACK-to-ACK error in transmission is lower than the probability for an ACK-to-NACK error. Multiple ACK/NACK bits are transmitted along with one or more side information bits that indicate the relative quantities of ACK values and NACK values among the ACK/NACK bits. In an exemplary method for generating error control information in a communication device, a plurality of ACK/NACK bits indicating whether corresponding transport blocks were successfully received are generated. One or more side information bits are formed as a function of the ACK/NACK bits, the side information bits indicating the relative quantities of ACK values and NACK values among the ACK/NACK bits, and transmitted along with the ACK/NACK bits to the remote communication node.
