摘要： The exemplary embodiments provide at least a method of receiving, by a node of a wireless communication network, more than one indication of data required to be sent from devices in the network, determining that provisioning resources to send the data in response to each of the more than one indication exceeds at least one threshold, and based on the determining, sending a probe message including a priority constraint to the devices. Further, receiving, at a device of a wireless communication network, a probe message from a network node of the network, the probe message identifying a priority constraint, sending, by the device, an acknowledgement to the probe message, the acknowledgment indicating that the device has data to send which meets or exceeds the priority constraint identified in the probe message, and in response to the acknowledgment, receiving from the network node a resource allocation to send the data.

摘要： Technologies are generally described for quiet period management in secondary opportunistic networks. Access Points (APs) in close proximity may form an ad hoc network (e.g., IEEE 802.11af) and instead of sensing and detecting idle channels in TV white spaces, listen to the broadcast messages from a co-existence manager, which broadcasts periodic intraframe sensing (IRFS) and interframe sensing (IFS) information in Medium Access Control (MAC) packets. The APs may extract information regarding the operating channels of the active cognitive base stations and their scheduled IRFS and IFSs on these channels. According to one scheme, short IRFS intervals over active channels may be allocated in a dedicated manner using a unique access request packet (ARP) by emergency network APs. According to another scheme, contention-based access may be provided to longer IFS intervals on multiple channels.

摘要： This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

摘要： Methods and devices are described in which an access point of a wireless network sends rendezvous time information to one or multiple associated stations. The rendezvous time information indicates a point in time at which the access point will try to access the wireless channel and schedule traffic for the stations. Based on that information, the stations will be able to decide if it is worth going into sleep mode until that rendezvous time or if it should stay awake.

摘要： Apparatuses, computer readable media, and methods for scheduling trigger frames in a high-efficiency wireless (HEW) local-area network are disclosed. An apparatus of a HEW master station is disclosed. The HEW master station includes transceiver circuitry and processing circuitry configured to transmit a random access trigger frame (TF-R) to a plurality of HEW stations, and receive resource requests from one or more of the plurality of HEW stations in response to the TF-R. The transceiver circuitry and processing circuitry is further configured to transmit an indication when a trigger frame is to be transmitted. The trigger frame is to comprise resource allocations in response to the resource requests. An apparatus of a HEW station may enter a power save mode until a time when a trigger frame is scheduled that includes resource allocations in response to resource requests transmitted to a master station from the HEW station.

摘要： Embodiments of a user station (STA), access point (AP), and method for random access contention in a wireless network are generally described herein. The STA may receive, from the AP, a beacon frame for a beacon interval. The STA may further receive a first random access Trigger Frame (TF) that indicates a first allocation of channel resources for random access contention by STAs during a first uplink transmission period of the beacon interval. The beacon frame may include a transmission timing for the first random access TF and a first TF cascade type for the first random access TF. The first TF cascade type may indicate whether a next TF is a random access TF or a scheduled access TF.
