Abstract: This disclosure above describes a method, a device, and a system for encrypting/decrypting physical channels in a wireless communication network. Among various embodiments are: pre-allocating a key, dynamically granting a key, encrypting the physical channel based on key in various levels, dividing the spectrum into two categories, or dividing a network into an initial access network and a private network. In one embodiment, a method for physical channel encryption is disclosed. Performed by a UE, the method may include obtaining a first key for decrypting a first physical channel, the first physical channel being encrypted; and decrypting the first physical channel based on the first key to obtain a signal or data transmitted by a first network element, the signal or the data being carried in the first physical channel.

Abstract: Bidirectional circularly polarized antenna element and bidirectional circularly polarized array antenna are provided, and comprising a dielectric substrate, a feeder, a radiation patch, a first plane, a second plane, a first coupling assembly and a second coupling assembly which are embedded in the surface of the dielectric substrate. The first plane and the second plane of the antenna element are kept at different heights, and compared with the solution that two planes at the same height can only generate linear polarization radiation in the prior art, the circular polarization radiation can be generated, which solves the problem of linear polarization mismatch. Furthermore, two coupling assemblies are introduced into two sides of the radiation patch to enable the coupling effect with the radiation patch, such that the frequency bandwidth of the circularly polarized antenna can be greatly improved without increasing the size of the antenna.
