摘要: A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

摘要: A wireless device that automatically forms a connection to a remote device in accordance with a peer-to-peer protocol. The remote device may be designated as an auto-connect device for the wireless device such that, when the wireless device determines that it is in the vicinity of the auto-connect device, it can re-form a connection to the remote device based on stored information for re-establishing connections among a persistent group of devices, but without any express user input. When a user requests that the wireless device perform a function that involves interaction with an auto-connect device, that function may be performed with the delay associated with forming a connection. Any of multiple techniques may be employed for identifying devices designated as auto-connect devices and for determining when the wireless device and a remote, auto-connect devices are in close proximity.

摘要: The concepts relate to radio white space utilization. One example can measure a potential radio white space frequency. The example can also communicate results of the measuring for other devices and receive other results from the other devices relating to the potential radio white space frequency. The method can further determine whether the potential radio white space frequency is actually an available radio white space frequency based upon the results and the other results.

摘要: The concepts relate to broadcasting white space utilization. One example can function as a client relative to a wireless access point that is configured to obtain authorization to utilize a radio white space frequency according to a set of constraints. The example can function as a Wi-Fi direct group owner to establish a Wi-Fi connection with a device that is not the wireless access point. This example can also transmit data over the radio white space frequency to the device in compliance with the set of constraints.

摘要: The concepts relate to broadcasting white space utilization. One example can interact with a wireless device that is configured to obtain authorization to use a set of radio white space frequencies in accordance with one or more constraints. The example can obtain an individual radio white space frequency and associated individual constraints. This example can also utilize the individual radio white space frequency for network access independent from the wireless device that is configured to obtain the authorization.

摘要: Methods and apparatus for improving the efficient use of a wireless channel. Flows of compatible packets to be transmitted are processed in separate queues based on characteristics of the packets, destination and quality of service (QoS) requirements. Aggregation parameters selected for each flow define when packets aggregated on a flow are to be sent. The aggregation parameters may reflect packet type, such as QoS requirements, an application type and/or wireless channel conditions. In some embodiments, the aggregation parameters indicate a threshold frame size or include a threshold time to buffer a packet while waiting for other packets on that flow to fill a frame. When an aggregation parameter for a queue is met, the aggregated packets are transmitted as a frame. The queue is cleared and subsequent packets may begin aggregating. Some types of packets, such as acknowledgment packets, may be sent without aggregation.

摘要: Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, UWB or any other suitable wireless technology. As one example, particular services may be requested. As another example, services that are provided by a device may be advertised.

摘要: A computing device including an indicator predicting use of a network resource. The indicator may provide an indication that a threshold associated with a budget for the network resource has or will be reached. When a user requests a network operation that will consume the network resource, an amount of the network resource to be consumed by the operation is predicted, if possible. If the prior use of the network resource and the amount to be used to complete the network operation exceeds a threshold the user may be warned and given an opportunity to cancel the operation or adjust the way in which the operation will be performed. If the amount of network resource a network operation will consume is unknown, a rate of use of the network resource is determined and a time until the budget is reached is estimated. An administrative tool is provided for managing network resources and setting budgets for resource consumption by users, devices, or applications.
