Methods, systems, and apparatus, including computer program products, in which access allocations to a spectrum band and transmit rights to the access allocations are defined. Real-time auction bids for the transmit rights to the access allocations to the spectrum band are sent from a participating device, and the participating device iteratively increments the bids until a maximum bid is reached or a transmit right is awarded to the participating device.
摘要:
The present invention provides efficient and effective quality of service for information that is time sensitive (e.g., real time data). An intermediate network communication system and method (e.g., a router) of the present invention performs cut through switching to reduce latency problems for time sensitive information. In one embodiment of the present invention, communication packet header information is encoded with a time sensitive identifier that identifies the information as time sensitive. In one exemplary transfer control protocol/internet protocol TCP/IP implementation of the present invention, time sensitive indication is provided in the link layer information. In one embodiment of the present invention, time sensitive information is dropped if the intermediate network device can not communicate the information within specified timing constraints. In one embodiment of the present invention time sensitive information is cut through routed on a virtual channel and pre-empts non time sensitive information. In one embodiment a communication path probe is cut through routed via intermediate network devices to establish a communication path before other information is communicated from a originating source to a final destination. In one embodiment the present invention leverages previously collected information to establish a communication path. In one embodiment the present invention, an intermediate network device establishes a second communication link if a first communication link is unavailable.

A method can include receiving, at an electronic transmitter device, for communication to an electronic receiver device, a first data value corresponding to one of a plurality of predetermined data values; identifying, from a matrix of data bits having the form of a 2N×2N Hadamard matrix whose rows have been randomly or pseudo-randomly shuffled, a column of data bits that is associated with the first data value; and transmitting to the electronic receiver device, in place of the first data value, the identified column of data bits. The method can further include receiving data at the electronic receiver; correlating the received data to the identified column of data bits; and providing the first data value for further processing by the electronic receiver.
摘要:
A method of improving bandwidth of wireless CDMA systems by shuffling the rows of a Hadamard function in a pseudo-random manner. A Hadamard function is used to provide orthogonality between users. The orthogonal waveforms are used to prevent interference from different users sharing the same cell as well as multiple channels from the same user. The rows of the Hadamard function are shuffled in a pseudo-random manner. This effectively maximally spreads the spectral density of the transmitted signal out across the available spectrum. These codes are pre-computed and stored in lookup tables of mobile wireless devices. The data signals are modulated by one set of codes. Thereby, one data bit can be transmitted per chip.
摘要:
Methods, systems, and apparatus, including computer program products, for implementing interference cancellation across base stations. Communications information for transmitting to a receiving device is received from a first base station at a second base station. At the second base station, second communications information is generated for transmission to the receiving device from the second base station. The second communications information comprises data to reduce interference with the first communications information.

A computer-implemented method may include receiving, at the base station, an identification and request for transmission access from a wireless computing device, determining a level of efficiency for data communications between the base station and the wireless computing device, selecting a descriptor for the level of efficiency, from among a plurality of predetermined descriptors that identify discrete efficiency classifications across a range of efficiencies, determining a share of bandwidth for communication between the base station and the wireless computing device based on the selected descriptor, and communicating electronically with the wireless computing device using the selected share of bandwidth. A higher share of bandwidth may be selected for a wireless computing device having a higher determined level of efficiency.
摘要:
A computer-implemented method may include receiving at a wireless device one or more beacon packets sent by a communication base station, determining a delay period at the wireless device, wherein the delay period is determined so that a delay for the wireless device is different than a delay for another wireless device, sending a first association request from the wireless device after waiting for the delay period, and establishing communication with the base station if an association response is received from the base station within a determined time period. The first association request may include information identifying the wireless device and an association code.
