    摘要: Methods, systems, and devices are described for intercepting socket calls from applications installed on a mobile device while a first wireless interface is active. The first wireless interface is a cellular interface. Upon determining to release the intercepted socket calls to the socket layer, a second wireless interface is activated. The second wireless interface is a Wireless Local Area Network (WLAN) interface. The sockets calls are released to the socket layer and transmitted using the activated second wireless interface. Upon substantially completing the socket calls, the second wireless interface is deactivated. The intercepting of the socket calls and the activation of the second wireless interface occurs while the mobile device is in an idle mode.

    摘要: The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is too performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.

    摘要: Methods, systems, and devices are described for discovering and associating with WLAN using Request to Send (RTS) and Clear to Send (CTS) frames. A mobile device may identify a WLAN access point associated with a location of the mobile device. The mobile device may transmit a Request to Send (RTS) frame to the access point and receive a CTS frame from the access point. The mobile device may determine that the access point is within range of the mobile device based on the received CTS frame. Some embodiments may provide for transmitting an association request frame to the access point in response to the received CTS frame. The association request frame may be transmitted to the access point in a time period associated with the CTS frame.

    摘要: Systems and methods are provided for a learning-based determination of semi-persistent scheduling of data-packet flow wireless communication. A packetized data flow served to a wireless terminal is fully scheduled for an initial period of time in order to collect statistics associated with scheduled packet sizes (Ss) and inter-packet times (Ts). Analysis of a cumulative distribution of {S, T} pairs indicate whether a characteristic packet size (S0) and size dispersion (D0) are associated with the cumulative distribution. Inter-time intervals associated with the characteristic size and dispersion complete a transport format. Semi-persistent scheduling is utilized for a packetized flow when a characteristic transport format can be extracted, or learned, from the accumulated statistics. Extracted transport formats can be employed to optimize scheduling efficiency upon handover.

    摘要: Techniques for selecting rates for data transmission on eigenmodes of a MIMO channel are described. An access point transmits an unsteered MIMO pilot via the downlink. A user terminal estimates the downlink channel quality based on the downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality and obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for the eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information. The access point processes data based on the selected rates and transmits steered data and a steered MIMO pilot on the eigenmodes with the eigenvectors.

    摘要: Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.
