    Abstract: Methods and apparatuses are described herein for network discovery. A wireless transmit/receive unit (WTRU) may transmit, to a first access point (AP), via a Primary Connectivity Radio (PCR), a request indicating that on a condition that the WTRU is disassociated from the first AP, the WTRU will enter a wake-up radio (WUR) only discovery mode. The WTRU may receive, from the first AP, via the PCR, a management frame that has WUR discovery elements including an indication of at least one channel used by a second AP. The WTRU may perform disassociation from the first AP. The WTRU may activate a WUR and deactivate the PCR. On a condition that the WTRU is disassociated from the first AP, the WTRU may receive, from the second AP, via the WUR, a WUR frame over the at least one channel to enable the WTRU to activate the PCR to initiate association.

    Abstract: Methods and apparatuses are described herein for feedback based midamble adaptation. For example, a first station (STA) may transmit, to a second STA, a request frame that includes an indicator indicating a request for midamble information. The first STA may receive, from the second STA, a response frame that includes the midamble information determined by the second STA based on one or more channel measurements associated with the second STA. The midamble information may include a midamble report, a Doppler measurement report, or the like. The midamble report or the Doppler measurement report may include at least one of a midamble periodicity, a mobility/Doppler level, or the like. Based on the midamble information, the first STA may generate a physical layer convergence procedure (PLCP) protocol data unit (PPDU) that includes at least one midamble within a data portion of the PPDU.

    Abstract: A method for use in a wireless transmit/receive unit (WTRU) is disclosed. The method comprises: generating, by a Station Management Entity (SME), a request primitive enabling a wake-up radio (WUR) scanning process for WUR discovery frames transmitted by one or more access points (APs), the request primitive comprising a plurality of first parameters; conducting the WUR scanning process using WUR based on the plurality of the first parameters; generating, at a MAC layer, at least one confirm primitive based on a result of the WUR scanning process and at least a part of the plurality of first parameters; and communicating, from the MAC layer to the SME, the at least one confirm primitive.

    Abstract: A method for active scanning in a wireless network may include two transmitters. In such a method, the following steps may take place: initiating active scanning on at least one of a plurality of channels; waiting to transmit a first probe request on a first channel of the plurality of channels based on a delay timer; receiving at the first STA, while the delay timer is not expired, a probe request from a second STA; and skipping the first probe request on the first channel of the plurality of channels based on information contained in the received probe request from the second STA.

    Abstract translation: 在无线网络中主动扫描的方法可以包括两个发射机。 在这种方法中，可以进行以下步骤：在多个通道中的至少一个上启动主动扫描; 等待基于延迟定时器在所述多个信道的第一信道上发送第一探测请求; 在所述延迟定时器未到期的情况下，在所述第一STA处接收来自第二STA的探测请求; 并且基于来自所述第二STA的所接收的探测请求中包含的信息，跳过所述多个信道的所述第一信道上的所述第一探测请求。
