摘要

Methods, apparatuses, and computer readable media for dynamic resource unit allocation for wireless local-area networks (WLANs) include an apparatus of an access point (AP) including processing circuitry configured to determine a group of stations (STAs) and first RUs for uplink (UL) multi-user (MU) orthogonal frequency division multiple-access (OFDMA) transmissions. The processing circuitry is further configured to transmit a trigger frame (TF) including indications of the determined first RUs for the group of STAs to transmit trigger-based (TB) physical layer (PHY) protocol data unit (PPDUs) (TB PPDUs) in response to the TF. The processing circuitry may be further configured to in response to a STA not responding to the TF, determine the STA as being inactive, and reallocate to active STAs RUs of inactive STAs, and transmit a second TF to the group of STAs that are active.

說明書

The method 1500 may be performed by an EHT/HE AP, e.g., EHT AP 502, and/or by an apparatus of an EHT/HE AP. The operations of method 1500 may be performed in a different order, in accordance with some embodiments. The method 1500 may include one or more additional operations in accordance with some embodiments. One or more of the operations of method 1500 may be optional, in accordance with some embodiments.

FIGS. 16-20 illustrate an example of dynamic RU allocation, in accordance with some embodiments. FIGS. 16-20 illustrate an example of an AP or apparatus of an AP performing a method of dynamic RU allocation. In some embodiments, FIGS. 16-20 illustrate the method 1200 being performed by an apparatus of an AP or an AP. The UL group of STAs consists of eight (8) STAs and each STA occupies a 10 MHz RU initially. The RU sizes are 10 MHz, 20 MHz, 40 MHz, and 80 MHz, although different RU sizes may be used.
