Abstract: An asymmetric handshaking design between an access point (AP) and a station (STA) is introduced. An access point is controlled to transmit packets in a first packet format. In response to packets transmitted from the access point in the first packet format, a station is switched to use a second packet format to transmit packets to form asymmetric handshaking with the access point when the station fails to use the first packet format to answer the access point.

Abstract: Embodiments of the present invention provide secure ranging measurements for wireless devices in multi-user (MU) mode. Specifically, a signaling procedure between an initiating wireless station (ISTA) and a responding wireless station (RSTA) is used to enable protection of randomized LTF sequences used in the secure ranging measurements. The signaling procedure may be performed in a HEz or VHTz mode and may include performing error recovery when operating in the HEz mode.

Abstract: A station (STA) for communicating with an Access Point (AP) in a wireless communication system is provided. The STA may include a wireless transceiver and a processor. The wireless transceiver may be configured to perform wireless transmission and reception to and from the AP. The processor may be configured to receive allocation information from the AP via the wireless transceiver, wherein the allocation information indicates at least one user block and at least one stream for the STA, wherein each resource unit (RU) in a Physical layer Protocol Data Unit (PPDU) comprises at least one user block, and send Uplink (UL) data or receive Downlink (DL) data in the at least one user block to or from the AP via the wireless transceiver according to the allocation information.

Abstract: Methods and apparatus for performing secure ranging measurements between wireless devices are disclosed herein according to embodiments of the present invention. The described embodiments use key values to indicate which LTF sequence (e.g., LTF measurement exchange) to use for performing wireless ranging measurements. A LTF sequence that is received by a wireless device that does not correspond with the associated key value is determined to be invalid. Invalid LTF sequences may be disregarded as signal noise.

Abstract: A device-centric discovery mechanism requiring very low power consumption to find out information about each other directly in a self-managed mobile environment is proposed. A mobile communications device joins a self-managed communications network, which does not have a centralized management entity. The mobile device receives a request from a peer communications device about publishing a service or subscribing to a service in accordance with a first schedule. The mobile device announce the request on behalf of the peer communications device in accordance with a second schedule. The service is then provided by a service advertiser to a service seeker in accordance with a third schedule.
