Abstract: Embodiments of fast steering timing and resource allocation are generally described herein. In some embodiments, a non-access point station (STA) decodes a fast steering timing signaling element (STSE) at a Narrow Band Control sub-Channel (NB-C-CH) and from an allocator device, the STSE indicating at least fast steering timing information, an identified Narrow Band Service sub-Channel (NB-S-CH), resource allocation information for the identified NB-S-CH, and connectivity information for the identified NB-S-CH, the identified NB-S-CH being selected from a plurality of NB-S-CHs. The STA exchanges packets in the NB-S-CH according to the resource allocation information and the connectivity information and based on the fast steering timing information. The STA encodes or decodes data associated with the exchanged packets.

Abstract: 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.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of determining one or more link adaptation parameters. For example, an apparatus may be configured to process a first message from a wireless station, the first message including location information corresponding to a location of the wireless station, and an Access Point (AP) identifier to identify an AP; to query a Location-Based Link Status (LB-LS) database (DB) for radio link information corresponding to the AP and to the location; to determine, based on the radio link information, one or more link adaptation parameters corresponding to a wireless link between the AP and the wireless station at the location; and to send to the wireless station a second message comprising the one or more link adaptation parameters.
