    摘要: The present disclosure relates to Hybrid Automatic Repeat Request (HARQ) in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. One example transmitting device is configured to encapsulate a data unit in a container unit, and encode the container unit into a codeword set of one or more codewords. One example receiving device is configured to receive, from a transmitting device, at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. A bit-size of the container unit is equal to a bit-size of the codeword set in the transmitting device and the receiving device.

    摘要: A communication transmitter retransmits a Medium Access Control (MAC) Protocol Data unit (MPDU) to a communication receiver over a communication channel using a Hybrid Automatic Repeat reQuest (HARQ) retransmission scheme. The MPDU includes a plurality of information bits. The communication transmitter includes a processor configured to determine the MPDU to be retransmitted based on a Block ACK frame received from the communication receiver, the Block ACK frame indicating previously correctly decoded MPDUs at the communication receiver, and to generate a bit sequence to be transmitted to the communication receiver, wherein the bit sequence comprises the plurality of information bits. The communication transmitter further comprises a communication interface configured to transmit the bit sequence to the communication receiver for retransmitting the MPDU to the communication receiver.

    摘要: A positioning method and apparatus, a WLAN device, and a storage medium are disclosed, and relates to the field of positioning technologies. The positioning method includes: a WLAN device obtains an uplink scheduling parameter sent by another WLAN device to a plurality of to-be-positioned WLAN devices, where the uplink scheduling parameter is used to indicate radio resources allocated to the plurality of to-be-positioned WLAN devices; the WLAN device receives uplink signals; and the WLAN device measures respective positioning data of the plurality of to-be-positioned WLAN devices based on the radio resources of the plurality of to-be-positioned WLAN devices and the received uplink signals. The embodiments can improve positioning timeliness of the to-be-positioned WLAN devices.

    摘要: The present invention relates to HARQ, particularly for IEEE 802.11, i.e. Wi-Fi. The invention proposes a transmitting device for supporting such HARQ, in which the order of scrambling and encoding is changed compared to the conventional transmitter. Likewise the invention proposes a receiving device for supporting such HARQ, in which the order of descrambling and decoding is changed compared to the conventional receiver. In particular, the transmitting device is configured to encode at least one data unit using Forward Error Correction (FEC) coding, scramble the encoded data unit based on a scrambling seed, provide an indication of the scrambling seed that is separate from the scrambled and encoded data unit, and transmit the indication of the scrambling seed and then the scrambled and encoded data unit to a receiving device.
