摘要： Systems and methods for enhanced link adaptation are provided. In some embodiments, a method of operation of a network node includes calculating an actual RE efficiency based at least in part on an actual TBS obtained from a specification. The TBS may be obtained from a specification based on LA result and actual buffer data volume. The method also includes determining a real BLER from a searchable repository, based on the actual RE efficiency and an actual BLER. The method may further include calculating an actual outer-loop adjustment (OLA) step based on the actual BLER. The method may further include a dynamic outer-loop up/down step adjustment based on the actual OLA step.

摘要： Methods and devices in a wireless communication system are provided, in which a first portion and a second portion of signals are transmitted on a physical channel to a first transceiver from a second transceiver. A method for controlling transmission parameters in the wireless communication system comprises the steps of: transmitting an indication indicating that the first and the second receiver processing algorithms are used in the first transceiver to process the first and second portions, respectively, of signals received on the physical channel; receiving the indication at the second transceiver; and adjusting, at the second transceiver in response to the indication, a transmission parameter for at least one of the first and second portions of signals to be transmitted on the physical channel to the first transceiver. The indication could be transmitted from the first transceiver, or it could be determined through evaluations carried out at the second transceiver.

摘要： Microwave switch (MS) comprising an antenna branch (AB), a receive branch (RB), and a transmit branch (TB). According to one embodiment, the switch comprises a protection circuit (CPL, DTC, CTRL), which upon a high power signal (Dtc_h) being present on the antenna branch effectuates a biasing of semiconductors on both the receive branch (RB) and the transmit branch (TB). According to one embodiment PIN diodes are provided for controlling switching between the transmit and the receiv branch as well as enabling a protective mode, the control being accomplished by selectively biasing respective diodes.

摘要： In a method and a device for partial encryption and progressive transmission of images, a first section of the image file is compressed at reduced quality without decryption, and a second section of the image file is encrypted. Users having access to appropriate decryption keywords can decrypt this second section. The first section together with the decrypted second section can then be viewed as a full quality image. The storage space required for storing the first and section together is essentially the same as the storage space required for storing the unencrypted full quality image. By using the method and device as described herein storage and bandwidth requirements for partially encrypted images is reduced. Furthermore, object based composition and processing of encrypted objects are facilitated, and ROIs can be encrypted. Also, the shape of a ROI can be encrypted and the original object can be decrypted and restored in the compressed domain.
摘要翻译： 在用于部分加密和逐行传输图像的方法和装置中，图像文件的第一部分以降低的质量被压缩而不进行解密，图像文件的第二部分被加密。 访问适当解密关键字的用户可以解密第二部分。 第一部分与解密的第二部分可以被看作是一个完整的质量图像。 将第一部分和部分一起存储所需的存储空间与存储未加密的全质量图像所需的存储空间基本相同。 通过使用如本文所述的方法和设备，部分加密的图像的存储和带宽要求降低。 此外，加密对象的基于对象的组合和处理变得容易，并且可以对ROI进行加密。 此外，ROI的形状可以被加密，并且可以在压缩域中解密和恢复原始对象。
