Abstract:
Apparatuses and methods of power save for wireless access point and multi-hop relays are disclosed. In one innovation, an apparatus comprises a memory unit configured to store latency information received from the at least one communication device and a processor operationally coupled to the memory unit and configured to retrieve the latency information from the memory unit and determine a sleep-cycle for the apparatus based on the latency information, the sleep-cycle indicating a time period when the apparatus will not receive signals and will not send signals.
Abstract:
Methods, devices, and computer program products for transmitting and receiving discovery and paging messages in a wireless communication device are described herein. In one aspect, a wireless apparatus operable in a wireless communication system comprises a processor configured to obfuscate a medium access control address of a frame by generating a random number and a transient address obfuscation key including a first transient key, wherein the transient address obfuscation key is a function of an address obfuscation key and the random number; including the random number in an address obfuscation header field of the frame; and replacing an original first address in an address field of the frame with a new first address that is a function of the original first address and the first transient key. The processor is further configured to include an indication of the obfuscation in a first field of the frame. The wireless apparatus further comprises a transmitter configured to transmit the frame to a receiving device.
Abstract:
Methods, devices, and computer program products for transmitting and receiving discovery and paging messages in a wireless communication device are described herein. In one aspect, a wireless apparatus operable in a wireless communication system comprises a transmitter configured to transmit a medium access control change request message to an access terminal to initiate a change in a medium access control address of the wireless apparatus and a receiver configured to receive a medium access control change response message from the access terminal. The wireless apparatus further comprises a processor configured to change the medium access control address of the wireless apparatus in response to receiving the medium access control change response, wherein the transmitter is configured to transmit a medium access control change confirm message to the access terminal.
Abstract:
Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a MAC header with a frame control field. The sub-fields included in a particular frame control field may be based on the type of information to be communicated to the receiving device.
Abstract:
A particular method includes generating, at a mobile station, a probe request frame and a service discovery request. At least a first portion of the service discovery request may be encapsulated within the probe request frame to form a modified probe request frame. The modified probe request frame may be wirelessly transmitted, for example, to a particular access point or to all access points with range of the mobile station.
Abstract:
Systems, methods, and devices for securely communicating data are described herein. In some aspects, a station is configured to communicate with an access point. A relay includes an uncontrolled port and a controlled port. The relay is configured to forward association, authentication, and secure relay setup frames between the station and the access point through the uncontrolled port. The relay is configured to forward data packets between the station and the access point through the uncontrolled port once the station establishes a relay relationship with the relay.
Abstract:
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, an access point is configured to receive a request for relay connection and to transmit a message to at least one relay based on the received request for relay connection. The message comprises an instruction to transmit a setup response frame. A station is configured to transmit the request for relay connection to the access point and to select one of the at least one relay based on at least one setup response frame received from at least one of the at least one relay. The selected one of the at least one relay is configured to relay data packets between the station and the access point.
Abstract:
A method for wireless communications is disclosed that includes receiving a plurality of requests to transmit data from a plurality of apparatuses; determining resource allocation for a set of apparatuses in the plurality of apparatuses, wherein the determination is based on the plurality of requests; and transmitting a message comprising the resource allocation to the set of apparatuses to permit data transmission. Another method for wireless communications is disclosed that includes contending for access to a medium based on a request, by an apparatus, with a plurality of other apparatuses; receiving a message, the message comprising a resource allocation based on requests from the apparatus and the other apparatuses, wherein the resource allocation permits data transmission from the apparatus and some of the other apparatuses; and transmitting data by the apparatus based on the message. Apparatuses for performing the methods are also disclosed.
Abstract:
Systems, methods, and devices for compressing block acknowledgment (ACK) frames/packets are described herein. In some aspects, a method of communicating in a wireless network includes a compressed block acknowledgment frame including a bitmap, the bitmap indicating receipt of a plurality of fragments of a single data unit. The method further includes transmitting the compressed block acknowledgment frame.
Abstract:
Systems, methods, and devices for communicating short control frames are described herein. In some aspects, a method of wireless communication includes generating a control frame comprising a physical layer preamble having a signal field, the signal field including an indicator indicating the control frame is a control frame type of frame. The method further includes transmitting the control frame.
