摘要： An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

摘要： This disclosure provides methods, devices and systems that support communicating using orthogonal frequency division multiple access (OFDMA) according to a tone plan that supports 20 MHz subchannel puncturing within a wireless channel. In some aspects, a non-legacy tone plan may define a set of tones for a resource unit (RU) such that the RU does not overlap a 20 MHz subchannel boundary of the wireless channel. The locations of the set of tones in the non-legacy tone plan may be shifted relative to corresponding tones associated with a corresponding RU according to a legacy tone plan. One or more of the disclosed tone plans may enable puncturing of subchannels while making use of some RUs that would otherwise partially overlap a punctured subchannel in the legacy tone plan.

摘要： Co-existence between an Orthogonal Time Frequency Space (OTFS) modulation system and a Long Term Evolution (LTE) system is achieved by generating a number of transmission beams for a first group of user equipment operating using LTE, and a second group of user equipment operating using the OTFS protocol, and transmitting a first group of data packets formatted according to the LTE protocol to the first group of user equipment and a second group of data packets formatted according to the OTFS protocol to the second group of user equipment. The transmissions are performed by precoding and modulating the first group of data packets according to an LTE modulation scheme, and precoding and modulating the second group of data packets according to an OTFS modulation scheme.
