Abstract: A system and method for providing confidentiality against eavesdropping and authentication against impersonation attacks for advanced wireless communication systems are disclosed. The method exploits ARQ as a MAC layer mechanism and artificial noise as a physical layer mechanism with maximal ratio combining to achieve secrecy. An artificial noise, not requiring class space in the channel, is designed and added to the data package based on the QoS requirements and channel condition between legitimate parties. Basically, a special AN, which does not require null-space in the channel, is designed based on the QoS requirements and the channel condition between the legitimate parties and injected to the data packet. If the same packet is requested by the legitimate receiver (Bob), an AN cancelling signal is designed and added to the next packet. Then, an AN-free packet is obtained by using MRC process at Bob, while deteriorating the eavesdropper's performance.

Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

Abstract: Radio Frequency (RF) power back-off optimization techniques are described for specific absorption rate (SAR) compliance. A mobile device may be configured to intelligently modify antennas and radio device transmission levels to maintain compliance with SAR limits while minimally perturbing radio operations. The mobile device may implement a SAR optimization scheme that accounts for user presence and signal conditions to maintain compliance. Rather than setting a fixed back-off, user presence detectors may be employed along with information on current signal conditions to determine potential for excessive SAR exposure and selectively apply variable adjustments to RF transmission power (e.g., “back-offs”), accordingly. The mobile device may also be configured to report SAR conditions and/or mitigation actions to a base station to enable the base station to manage a connection to services based at least in part upon knowledge of SAR actions taken by the mobile computing device.
