Abstract: A system and method to substantially prevent Denial of Service (DoS) attacks due to Random Access Channel (RACH) overload in cellular wireless networks. Once a mobile handset is identified to cause or contribute significantly to a RACH overload of the cell, the system sends a special System Information Block (SIB) message targeted to that mobile handset and instructing it to redirect its RACH signaling to a separate RACH/PRACH (Physical Random Access Channel) resource or to a small part of the current RACH/PRACH resource. This allows most or all of the regular RACH/PRACH resource from being overloaded by a single user or a group of users. The use of a separate RACH/PRACH resource such as frequency, preamble sequence, and/or radio subframe access slot to “absorb” high volume RACH signaling traffic from a small number of malicious/defective mobile handsets substantially prevents the signaling DoS attacks in the wireless network and makes it more robust to such attacks.

Abstract: Compressive sampling is used to generate pilot symbols to be transmitted over an array of antennas in a MIMO wireless communications device. A pilot symbol is transmitted over the array of antennas according to a spatially randomized antenna transmission function that randomly changes across the array of antennas. The randomized antenna transmission function may randomly select/deselect antennas and/or randomly change amplitude and/or phase of the pilot symbol transmission. Channel estimates can be constructed at a receiver based on the spatially randomized pilot symbols that were transmitted.

Abstract: Multi-antenna transmission control presented herein involves generating a set of virtual channel realizations at the transmitter that shares the same second-order statistics as the actual channel realizations observed for a targeted receiver. By making the control-related quantities of interest at the transmitter depend on the long-term statistics of the channel, the actual channel realizations are not needed for transmission control, e.g., for accurate Multiple-Input-Multiple-Output (MIMO) preceding. As such, the use of virtual channel realizations enables transmission control that approaches the “closed-loop” channel capacity that would be provided by full feedback of the (instantaneous) actual channel realizations, without requiring the overhead signaling burden that attends full feedback.

Abstract translation: 本文提出的多天线传输控制涉及在发射机处生成一组虚拟信道实现，其共享与针对目标接收机观察到的实际信道实现相同的二阶统计。 通过使发射机处的控制相关数量取决于信道的长期统计，例如对于精确的多输入多输出（MIMO）预编码，传输控制不需要实际的信道实现。 因此，虚拟信道实现的使用使得接近将通过（瞬时）实际信道实现的完全反馈提供的“闭环”信道容量的传输控制，而不需要出现完全反馈的开销信令负担。

Abstract: Systems and methods are disclosed for efficient operation of wireless access nodes in a dense deployment of wireless access nodes in a cellular communication network. In general, the dense deployment of wireless access nodes includes multiple wireless access nodes in a service area. The service area is preferably, but not necessarily, a low-load service area. As used herein, a low-load service area is an area within an overall service area of the dense deployment of wireless access nodes in which all wireless access nodes are not needed to provide a desired data capacity. Overlapping radio coverage areas of the wireless access nodes in, or serving, the service area are leveraged to enable efficient operation of the wireless access nodes in the service area.
