  • Patent number: 11825233
    Abstract: Disclosed is a data transmission system having a transmitter and a receiver. The transmitter encodes external input signals to acquire coded transmission data transmitted in multiple paths with different frequency band, and then transmits them to respective receiver; and the receiver performs data fusion on the received transmission signals to acquire coded received data, and decodes it to acquire and output the decoded data. In conclusion, since the received signals are split into a plurality of transmission signals of different frequency bands by the transmitter and the signals are fused in the receiver, the signals are not susceptible to the same frequency interference during transmission, improving the anti-interference of the data transmission system, realizing high-reliability transmission at low cost or in a complex wireless environment, also expanding the applications of the data transmission system.

  • Patent number: 11622379
    Abstract: Examples of triggered single user (SU) transmissions are described. In an example, an access point (AP) may send a SU trigger frame to a client device for initiating a data transmission by the client device. The AP may detect whether the data transmission is initiated within the Short Interframe Spacing (SIFS) after the SU trigger frame is sent. Responsive to detecting that the data transmission is not initiated within the SIFS, the AP waits for the client device to initiate the data transmission within a predefined time interval after the SIFS. Responsive to detecting that the data transmission is not initiated within the predefined time interval, the AP repurposes the channel access after the predefined time interval is elapsed. Responsive to detecting that the data transmission is initiated within the predefined time interval, the AP repurposes channel access after one of an expiration of a maximum transmission opportunity (TXOP) duration and a completion of the data transmission, whichever is earlier.

  • Patent number: 11129144
    Abstract: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3<R?2/3, one bit is set. On the other hand, in a case where R?1/3, zero bits is set.

  • Patent number: 11088786
    Abstract: The present application describes a data processing method used for implementing data transmission between multiple carriers and a HARQ entity. A terminal receives mapping relationship information sent from a base station, where the mapping relationship information is used to indicate a mapping relationship between a HARQ entity of the terminal and a frequency resource configured by the base station for the terminal. The terminal determines the frequency resource. The terminal determines a HARQ entity corresponding to the frequency resource according to the mapping relationship information and processes a HARQ data block transmitted on the frequency resource by using the HARQ entity. Therefore, carrier communication channels for real-time transmission between the base station and the terminal are increased, to improve transmission efficiency.

  • Patent number: 11082187
    Abstract: Certain aspects of the present disclosure provide techniques for rate-matching data on a per transmission reception point (TRP) basis for single downlink control information (DCI) multi-TRP transmissions. Transmitters operating according to the present disclosure use a per TRP rate matching technique in which the rate-matching order is to first rate-match across spatial layers transmitted by a TRP, then across frequency, then across time, and then to another TRP, where remaining data is rate-matched across the spatial layers of that other TRP, then across frequency, and then across time. The described per TRP rate-matching technique causes code blocks of a transport block to be transmitted by one TRP, instead of each code block being transmitted by a group of TRPs.
