Abstract: Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.

Abstract: Embodiments described herein provide a method for cross-channel scheduling of high efficiency (HE) multi-user (MU) frame transmission. In some embodiments, channel information and client station information may be obtained for data transmission. An MU frame containing a data field of a first type and two data fields of a second type may be configured to carry scheduling information relating to one or more channels for the data transmission. It may be determined that a current scheduling setting of the two data fields of the second type leads to unbalanced payload between the one or more channels. The two data fields of the second type may then be adjusted for a balanced channel mapping, and the data field of the first type may be adjusted to reflect the balanced channel mapping. Data based on the adjusted data field of the first type and the adjusted two data fields of the second type may be transmitted via the one or more channels.
