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

Radio IC circuitry 106 as shown may include WLAN radio IC circuitry 106A and BT radio IC circuitry 106B. The WLAN radio IC circuitry 106A may include a receive signal path which may include circuitry to down-convert WLAN RF signals received from the FEM circuitry 104A and provide baseband signals to WI AN baseband processing circuitry 108A. BT radio IC circuitry 106B may in turn include a receive signal path which may include circuitry to down-convert BT RF signals received from the FEM circuitry 104B and provide baseband signals to BT baseband processing circuitry 108B. WLAN radio IC circuitry 106A may also include a transmit signal path which may include circuitry to up-convert WLAN baseband signals provided by the WLAN baseband processing circuitry 108A and provide WLAN RF output signals to the FEM circuitry 104A for subsequent wireless transmission by the one or more antennas 101. BT radio IC circuitry 106B may also include a transmit signal path which may include circuitry to up-convert BT baseband signals provided by the BT baseband processing circuitry 108B and provide BT RF output signals to the FEM circuitry 104B for subsequent wireless transmission by the one or more antennas 101. In the embodiment of FIG. 1, although radio IC circuitries 106A and 106B are shown as being distinct from one another, embodiments are not so limited, and include within their scope the use of a radio IC circuitry (not shown) that includes a transmit signal path and/or a receive signal path for both WLAN and BT signals, or the use of one or more radio IC circuitries where at least some of the radio IC circuitries share transmit and/or receive signal paths for both WLAN and BT signals.
