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(shuō)明書(shū)

In some embodiments, the radio-architecture 100 may include other radio cards, such as a cellular radio card configured for cellular (e.g., 3GPP such as LTE, LTE-Advanced or 5G communications).

In some IEEE 802.11 embodiments, the radio architecture 100 may be configured for communication over various channel bandwidths including bandwidths having center frequencies of about 900 MHz, 2.4 GHz, 5 GHz, and bandwidths of about 1 MHz, 2 MHz, 2.5 MHz, 4 MHz, 5 MHz, 8 MHz, 10 MHz, 16 MHz, 20 MHz, 40 MHz, 80 MHz (with contiguous bandwidths) or 80+80 MHz (160 MHz) (with non-contiguous bandwidths). In some embodiments, a 320 MHz channel bandwidth may be used. The scope of the embodiments is not limited with respect to the above center frequencies however.

FIG. 2 illustrates FEM circuitry 200 in accordance with some embodiments. The FEM circuitry 200 is one example of circuitry that may be suitable for use as the WLAN and/or BT FEM circuitry 104A/104B (FIG. 1), although other circuitry configurations may also be suitable.
