Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

Abstract: In 802.11ax networks with access points, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access points. To make more effective the usage of the network, the access point may design the trigger frame to force the nodes to send some categories of data. Resource units may be defined in trigger frames to be dedicated to small packets or to some access category data. Adjusting the time length of the resource units helps restricting the type of data that can be conveyed by the resource units. Also, using various frequency widths for resource units in the same trigger frame helps reducing padding in the resource units when various traffic types coexist.

Abstract: For more efficient use of the limited bandwidth in 5G and 6G communications, and to enable longer battery life in remote user devices, the user device can request that unnecessary downlink control messages be withheld. Instead, a custom search-space can be assigned to the user device, such that all downlink data messages will begin in one of the resource elements of the custom search-space, thereby greatly simplifying the user device's task of detecting its incoming messages in a stream of unrelated transmissions. In addition, the user device can request that the user device's identification code, and optionally the length of the data message, be prepended to the data message, for further assistance to low-cost reduced-capability user devices that do not require low latency.

A minimum bit rate can be decreased when it produces a relatively higher impact on network performance, and the minimum bit rate can be increased when it produces a relatively lower impact on network performance.
