  • Patent number: 11496208
    Abstract: Techniques for improving the efficiency of transmitting data between devices are described. In an example, a first device transmits first data to a second device during a first time interval, whereby the second device is configured to communicate with the first device in a half-duplex mode. During a second time interval, the first device receives second data from the second device. The first device then determines that the second device transmitted the second data during a third time interval that is between the first time and the second time, and during which a reception of the first data by the second device is expected. The first device then retransmits the first data based at least in part on determining that the second device transmitted the second data during the third time interval.

  • Patent number: 10826637
    Abstract: A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.
