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： Embodiments of a station (STA), access point (AP) and method for aggregation of data packets are generally described herein. The AP may transmit a trigger frame (TF) to an STA that indicates an access class (AC) constraint parameter and a traffic identifier (TID) aggregation limit parameter. The STA may select a group of aggregate TIDs from which medium access control (MAC) protocol data units (MPDUs) may be aggregated into an aggregated MPDU (A-MPDU). The AC constraint parameter may indicate a recommended AC from which at least a portion of the aggregate TIDs are to be selected. The TID aggregation limit parameter may indicate a number of TIDs to be selected for the group of aggregate TIDs.
