  • Publication number: 20230396477
    Abstract: A wireless communication device and a communication method for header repetition are described. The device and method receive and decode a wireless packet through a communication channel. Formats of the wireless packet includes a first packet format and a second packet format. In this regard, the first packet format comprises a first header field carried by a first orthogonal frequency division multiplexing (OFDM) symbol while the second packet format comprises both the first header field carried by the first OFDM symbol and a second header field carried by a second OFDM symbol which follows the first OFDM symbol. The second header field is a repetition of the first header field. According to an exemplary embodiment, the second packet format is distinguished from the first packet format by detecting, from the received wireless packet, the second header field which repeats the first header field.

  • Patent number: 11646927
    Abstract: An OFDM communication system is described that allows different values of D in a single domain where nodes are operating in different portions of frequency bands. For the power-line medium, G.9960 has defined two overlapped baseband bandplans, 50 MHz-PB and 100 MHz-PB. In this exemplary scenario, the level of frequency diversity is different depending on the bandplan, hence providing different header decodibility if D is fixed to 1. If D is fixed to 2, then it increases reliability for the narrowband devices, but may also unnecessarily increase overhead for the wide-band devices. An exemplary aspect is therefore directed to techniques to accommodate different repetitions schemes (D=1, . . . , DMAX and H=1, . . . , HMAX) in a single domain, and still allow devices to communicate with one another where DMAX and HMAX can be larger than 2.

  • Publication number: 20210360525
    Abstract: A method for transmitting a physical layer protocol data unit (PPDU) and a device using the same are provided. The device receives a trigger frame for requesting a transmission of a high efficiency (HE) trigger-based (TB) PPDU and transmits the HE TB PPDU. A duration of the HE TB PPDU is calculated based on a duration of the trigger frame.
