Abstract:
A key to configure a wireless device includes a non-volatile memory to store network configuration information including a unique network identifier. A circuit coupled to the non-volatile memory manages the network configuration information. An interface communicates data including the network configuration information with the wireless device.
Abstract:
Systems, devices, and techniques for V2X communications using multiple radio access technologies (RATs) are described herein. A communication associated with one or more of the multiple RATs may be received at a device. The device may include a transceiver interface with multiple connections to communicate with multiple transceiver chains. The multiple transceiver chains can be configured to support multiple RATs. Additionally, the multiple transceiver chains may be controlled via the multiple connections of the transceiver interface to coordinate the multiple RATs to complete the communication.
Abstract:
In a wireless network in which the base station has full duplex capability (can transmit on the downlink channel and simultaneously receive on the uplink channel), but the mobile stations have only half duplex capability (each can transmit on the uplink channel and receive on the downlink channel, but not simultaneously), the base station may transmit duplicate copies of multicast data in two or more frames. Some of the addressed mobile stations may be scheduled to receive the first frame and transmit during the second frame, while the other addressed mobile stations may be scheduled to transmit during the first frame and receive the second frame.
Abstract:
An embodiment of the present invention provides a method, comprising retransmitting Automatic Repeat request (ARQ) blocks from a subscriber station (SS) to a base station (BS) without waiting for a timer to expire or depending on an explicit NACK from the BS. An embodiment of the present invention may further comprise accomplishing the retransmission of ARQ blocks by performing ARQ acknowledgement state updates at the SS and BS that affect the other side at PHY frame boundary, keeping block transmission relationship to a PHY frame number at the SS, and positively deducing the outcome of a transmission at the sender by exploiting the temporal relationship between blocks transmitted in the same PHY frame.
Abstract:
Embodiments of wireless device and method for communicating in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, a wireless device establishes a link using a directional antenna in an initially selected direction with another wireless device. If the link in the initially selected direction deteriorates, the link may be reestablished in a previously identified alternate direction. In some embodiments, the initially selected direction and the alternate direction are jointly selected by both the first and second wireless devices.
Abstract:
Briefly, in accordance with one embodiment of the invention, an access point may preemptively broadcast an alternate channel to switch to, along with an indication of the beacon timing for the alternate channel, prior to any catastrophic interference. The access point may switch to the alternate channel in the event of interference on the original channel without attempting to broadcast the alternate channel during the interference event. A mobile user may then know in advance of the interference event which alternate channel the access point switched to and may switch to the alternate channel.
Abstract:
Briefly, in accordance with one embodiment of the invention, a client node transmits a wakeup notification message to a supporter node when the client node is in a higher power awake mode. The supporter node may transmit data, if any, to the client mode until there is no more data to be transmitted to the client node. The supporter node then transmits a done transmitting packet to the client mode when the buffer memory is empty to indicate there is no more data to be transmitted. Upon receiving a done transmitting packet, the client node may enter into a lower power sleep mode until a subsequent awake event. The wakeup notification message may be transmitted by the client node at a time or interval selected to provide a power savings to the client node.
Abstract:
A wireless local area network (WLAN) device transmits a header over an air interface, at a first modulation rate. The header may include an indication of a second modulation rate that will be used to transmit a consolidated payload. In one embodiment, the header includes information that enables a receiver to determine when an end of each of the multiple data units will occur. The device further transmits the consolidated payload at the second modulation rate. The consolidated payload includes multiple data units. In one embodiment, the consolidated payload includes information that enables the receiver to determine when an end of each of the multiple data units will occur.
Abstract:
A wireless local area network (WLAN) device transmits multiple data packets within a data burst. In various embodiments, after the first packet is transmitted, subsequent packets are transmitted before expiration of an Interframe Space (IFS). The subsequent packets may have a full-length preamble, a partial preamble or no preamble at all.
