    Abstract: Systems and methodologies are described that facilitate providing power control for intermediary access points in wireless networks, such as relay nodes. Parameters related to intermediary access point communications can be provided to a serving access point, and the serving access point can generate power adjustment values and related commands based at least in part on the parameters. The parameters can include load on the intermediary access point, signal-to-interference-and-noise ratio (SINR) and/or similar parameters related to communications between the intermediary access points and/or one or more UEs, etc. In addition, end-to-end power control can be provided where intermediary access points report SINR to serving access points allowing serving access points to adjust downlink transmission power.

    Abstract: Techniques for supporting communication by a relay station are described. In an aspect, the relay station may support NACK Type 1 when operating in an amplify-and-forward (AF) mode. The relay station may receive a first transmission of a packet from an upstream station, determine PAPR of the first transmission, and send NACK Type 1 to the upstream station if high PAPR is detected. In another aspect, the relay station may support NACK Type 1 and NACK Type 2 when operating in a decode-and-forward (DF) mode. The relay station may perform PAPR decoding for the first transmission, send NACK Type 1 if PAPR decoding fails, perform channel decoding if PAPR decoding passes, and send NACK Type 2 to the upstream station if channel decoding fails. In yet another aspect, the relay station may operate in the AF mode or the DF mode.

    Abstract translation: 描述了用于支持中继站通信的技术。 在一方面,当以放大转发(AF)模式操作时,中继站可以支持NACK类型1。 中继站可以接收来自上游站的分组的第一次传输,确定第一传输的PAPR,并且如果检测到高PAPR,则将NACK类型1发送到上游站。 在另一方面,当以解码转发(DF)模式工作时,中继站可以支持NACK类型1和NACK类型2。 如果PAPR解码失败,则中继站可以执行PAPR解码,如果PAPR解码失败,则发送NACK类型1,如果PAPR解码通过则执行信道解码,如果信道解码失败,则将NACK类型2发送到上游站。 在另一方面,中继站可以在AF模式或DF模式下操作。

    Abstract: Methods, apparatus, and computer program products are herein described that provide for an identity-based cryptosystem using a highly secure biometric model through which both access and data transmission are effectively made very secure. Through implementation of generating and securely storing biometric data as syndrome vectors tolerance is provided for the inherent variability of biometric data. In addition, to insure that the biometric data is not duplicated by adversaries who might gain access to the syndrome generation algorithm and the biometric data, present aspects, provide for keeping the private key more secure and making the cryptosystem user-identity dependent. As such the systems, apparatus and computer program products herein disclosed provide end-to-end authentication of end users using secure biometry, which constitute the symmetric and/or asymmetric identity-based cryptosystem.
