A system and method in various embodiments implements a virtual spectrum band stacking technique facilitating spectrum sharing by converting and combining spectrum bands consisting of several different RF channels, common air interfaces, and radio channel protocols in the radio frequency channel domain to form IP Virtual Radio Channels (IP-VRCs) in the packet data domain. This virtual spectrum stacking technique combines the transmissions of contiguous and non-contiguous RF channels with differing physical layers into IP-VRCs. This technique enables simultaneous parallel high-speed wireless transmission; virtual radio channel hopping for enhanced security; and customized security schemes for different IP-VRC Groups. The deployment of the combination of IP-VRC Groups; Universal “Small Cell” Base Stations; and Universal Wireless End-Point Devices allows the aggregation of all available spectrum bands for use within a building environment. Some benefits of this deployment include expansion of spectrum utilization, service quality, security, applications and transmission throughput for wireless end-point devices.

A method and apparatus is disclosed whereby the scheduling of network transmissions in a wireless backhaul network is determined using a cross-layer optimization algorithm. In a first embodiment, the algorithm assumes a good MAC layer transmit schedule has been provided and computes optimal network layer routes as well as transmit beam patterns and transmit powers in a semi-distributed manner. According to this embodiment, the optimization goal is the throughput from each access point, or node in the network, to the core network. In another embodiment, an independent set of transmitting nodes is determined at the MAC layer in a way such that no link in the set interferes with another link and no link is scheduled to transmit and receive at the same time. According to this embodiment, a column generation algorithm is used to find a maximal weighted independent set and to achieve optimal network transmission throughput.

This invention relates to reception and transmission of data over a network. More specifically, this invention relates to Transmission Control Protocol's delayed acknowledgment and improving transmission throughput by adaptively adjusting the use of delayed acknowledgment.

A method and an apparatus select an access point (AP) in a wireless LAN to associate or reassociate, based on considerations that take into account the quality-of-service (QoS) status of the stations (STAs) and the potential hidden terminal effect. The method utilizes advertised or requested information obtained from an AP which includes the QoS status in each basic service set (BSS) and estimates the potential hidden terminal (HT) effect based on local channel sensing by the STA. The method selects the AP in a manner that reduces the possibility of collision from equal and higher priority HTs, thus providing greater transmission throughput and improving performance.

Wireless communication system and wireless communication method using a wireless channel. A transmitting device changes one of a data bitrate of a video signal and an actual transmission rate of the video signal based on a determination of a maximum transmission throughput of the wireless channel and transmits the video signal over the wireless channel according to the change in the data bitrate or the change in the actual transmission rate. A receiving device receives, temporarily stores, and decodes the video signal transmitted over the wireless channel. Thus, the wireless communication system is capable of maintaining a continuous video display when a discontinuous video signal is transmitted over the wireless channel.
