Abstract: A method of communication includes duplication of a first field of a first content channel into a third field in a third content channel and applying a modulation and coding scheme (MCS) to only one of the first field and the third field. The first content channel is a first portion of a frame and the third content channel is a third portion of the frame. Duplication of a second field of a second content channel into a fourth field in a fourth content channel and applying a modulation and coding scheme (MCS) to only one of the second field and the fourth field. The second content channel is a second portion of a frame and the fourth content channel is a fourth portion of the frame. The first content channel and the second content channel form a first group of content channels and the third content channel and the fourth content channel form a second group of content channels. The method then transmits the frame.

Abstract: In some embodiments disclosed herein a device 102 for network communication transmits an outbound WLAN frame to a remote device 104 via the network 100. The outbound frame includes a frame synchronization portion 802 followed by first ODFM. The device also receives an inbound WLAN frame 808 from the remote device. The inbound frame includes second OFDM symbols. One of: (a) the transmitted outbound frame and (b) the inbound frame, includes generation data 821 for generating the other of the outbound frame, by the device, and the inbound frame, by the remote device. The frame synchronization portion suspends transmission of the first OFDM symbols to be synchronized with the second OFDM symbols. Corresponding methods, computer programs and non-transient computer readable mediums are also disclosed.

Abstract: A method and system for providing utilization information for a basic service set (BSS) in a wireless local area network system, performed by an access point, including generating and transmitting a BSS load element including a capable STA count field, a plurality of frequency and/or spatial stream underutilization fields, and a plurality of delta observable secondary channel utilization fields. The capable STA count field indicates a total number of STAs currently associated with the BSS. Each of the frequency and/or spatial stream underutilization fields indicates underutilized frequency and/or spatial stream domain resources on Orthogonal Frequency Division Multiple Access resource units for each channel, and each of the frequency and/or spatial stream underutilization fields is calculated based on RU size. Each of the delta observable secondary channel utilization fields indicates a utilization for a subband within a secondary channel calculated based on observable utilization on the corresponding secondary channel.
