摘要： A method for generating a training sequence code (TSC) in a communication system. The method includes obtaining a full set of training sequence code candidates through joint channel estimation with consideration of a symbol delay of an interfering signal; optimizing cross-correlation properties for the full set; obtaining a subset for necessary training sequence codes among the training sequence code candidates; defining each of training sequence codes in the obtained subset as a reference sequence; and generating optimized training sequence codes by copying symbols of a predetermined number of bits located in the front of the reference sequence, arranging the copied symbols in Most Significant Positions (MSPs) as a guard sequence, copying symbols of a predetermined number of bits located in the rear of the reference sequence, and arranging the copied symbols in Least Significant Positions (LSPs) as a guard sequence.

摘要： Systems and methods for generating a control signal for automatic wireless network version detection of a transmission. The control signal enables a receiver to detect the wireless network version detection of the transmission, so that the proper wireless network version is used for interpreting signaling information and decoding of the payload of the transmission. In some examples, the control signal is within a preamble of the transmission. The wireless network version can be an IEEE 802.11 version, such as proposed IEEE 802.11be. The control signal is compatible with legacy systems and can indicate the legacy signaling information by way of a Legacy Signal (SIG) (L-SIG) symbol. In some examples, the control signal can indicate the wireless network version by using an identifier symbol which is generated from at least part of, but is not identical to, the L-SIG symbol.

摘要： Methods and systems for outputting data for transmission in a wireless local area network (WLAN) are disclosed. The method comprises generating a trigger frame for a first wireless communication device, the trigger frame comprising one or more subfields of bits at predefined bit locations within the trigger frame that are populated with values for a second wireless communication device to copy into a trigger based frame for transmission to the first wireless communication device.

摘要： Methods, devices and systems for allocating spectrum in a wireless local area network. A bit representation of the availability or unavailability of a plurality of sub-bands of a portion of frequency spectrum is generated and included in a physical layer protocol data unit, which is transmitted to a target station to allocate resource units within the portion of frequency spectrum for use by the target station. The sub-bands may be 20 MHz spectrum sub-bands for large-size resource units, or the portion of frequency spectrum may be a single 20 MHz band sub-divided into multiple sub-bands for allocating small-size resource units. A station that receives the data unit may decode the bit representation and use the allocated resource units to communicate over the wireless local area network.
