    Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive system information comprising first information of first time domain resource assignment for a physical downlink shared channel (PDSCH). The receiving circuitry is also configured to receive a UE-specific radio resource control (RRC) signal comprising second information of second time domain resource assignment for a PDSCH. The receiving circuitry is also configured to perform, based on a detection of a physical downlink control channel (PDCCH), the PDSCH reception according to either the first information of the first time domain resource assignment or the second information of the second time domain resource assignment.

  • Patent number: 11641479
    Abstract: In conventional cases that different trees are used between luma and chroma and that luma chroma prediction including multiplication in chroma intra prediction is used, there is a problem in that a processing delay caused by the chroma intra prediction is increased in small blocks. In a case that two different trees are used between luma and chroma, in a case of an 8×8 block in a luma size, 0 is derived without decoding qt_split_cu_flag, and in a case of an 8×4/4×8 block in a luma size, 0 is derived without decoding mtt_split_cu_flag. In a case that the size of a target block is smaller than a prescribed size, a chroma intra mode is derived from any one of DC, leftward prediction, and upward prediction.

  • Patent number: 9178600
    Abstract: A packet data transmission system comprises primary stations (PS) having signal transmitting and receiving means and antennas (PA1 to PA4) for propagating downlink signals and receiving uplink signals and a plurality of secondary stations (SS) able to roam within the coverage areas of the primary stations. Each secondary station (SS1) has signal transmitting and receiving means, a predetermined number of antennas (SA1 to SA4), and means for monitoring its radio environment. Information about the radio environment is relayed as an uplink signal to the respective primary station which modifies its mode of transmission of packet data signals. The secondary station in response to the modified mode of transmission of the downlink signals adapts its receiver resources to process the packet data signals and effect cancellation of any interference.

  • Patent number: 9178577
    Abstract: A radio communication system comprises a communication channel for the transmission of data packets (302) from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement (304) or a negative acknowledgement (306)) to the primary station for each of the plurality of packets. The signaling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.

  • Patent number: 9161336
    Abstract: In order to improve efficiency for sub-carrier allocation in a TDM multi-carrier system, the invention provides a novel frame structure and corresponding method and apparatus. During a centralized short period, each terminal sends a probe message including a predefined sequence to a network device and the network device estimates the channel characteristics for each sub-carrier with respect to each terminal by estimating the received probe message. In this way, sub-carrier allocation can be improved and sub-carriers with good channel characteristics are allocated to appropriate terminals.

  • Patent number: 9154200
    Abstract: The present invention relates to the signaling of channel quality information in a multi-beam transmission system, wherein a plurality of beams are simultaneously transmitted and a plurality of sets of channel quality information are transmitted for controlling independently the transmission rate on the different beams. Determined are beams with a different quality resulting in different effects of errors in the transmissions of the channel quality information for the beams. Said different effects are exploited for reducing a signaling overhead of the channel quality information for the beams.

  • Patent number: 9025548
    Abstract: A communication system comprises a downlink indicator channel (DL1) for the transmission of a indicator signal (302) indicating that a data packet (202) is scheduled to be transmitted on a downlink data channel (DLz) from a primary station to a secondary station. In operation, on detection of the indicator signal, the secondary station transmits a status signal, for example a negative acknowledgement signal (204), on an uplink channel (UL) to the primary station immediately before transmission of a positive (206) or negative acknowledgement signal to indicate the status of the received data packet. By providing the primary station with two chances to detect the case where the secondary station fails to detect the indicator signal, peak power requirements of the uplink channel can be reduced, thereby reducing system interference levels.

  • Patent number: 8971458
    Abstract: The present invention relates to space-time or space-frequency coding in cellular systems. The same data is transmitted from different antennas with different coverage areas, corresponding to different cells. The different data streams have different parts of the space-time block codes applied. A mobile terminal can combine the different parts of the space-time block codes in different received signals. This provides better performance than the known techniques for single frequency networks. The invention can also be applied to antennas with different coverage areas from the same site, and different beams formed with antenna arrays.

  • Patent number: 8953519
    Abstract: A method of transmitting a data signal in a wireless communication system from a primary station to a secondary station, where the data signal includes a medium access control header (MAC-hs header) and a protocol data unit associated with the medium access control header. The medium access control header includes a set of fields (TSN, SEG, LI, LCid). The method includes determining a size allocated to at least one field of the set based at least in part on a length of the protocol data unit. For example, the size allocated to a segmentation indication field (SEG) determined for a first length of the protocol data unit is lower than the one determined for a second length of the protocol data unit, where the second length being higher than said first length, where the segmentation indication indicates in how many segments the protocol data unit is subdivided.

  • Patent number: 8798015
    Abstract: Due to NACK-to-ACK misinterpretations in base stations, packets are lost, and there may be gaps in a re-ordering buffer of a base station. According to the present invention, when the receiver decodes—possibly after some retransmissions—a first data packet without an error, which first data packet is sent along with an indicator indicating that the first data packet is a new data packet, after the receiver has sent a negative confirmation message (NACK) with respect to a second data packet, the receiver sends a Revert (REV) message to the transmitter. The REV message informs the base station that the first data packet was decoded error-free, and that the second data packet is still missing on the receiving side so that the base station may re-send this second data packet.
