    Abstract: Methods, apparatus, and systems that relate to rate matching scheme design for polar coding, PAC coding, or other pre-transformed polar coding are disclosed. In one example aspect, a method for digital communication includes determining, by a first node, an output bit sequence having E bits based on an input bit sequence c having K bits, wherein the output bit sequence is determined based on an output of a polar transform and an output of a repetition operation, and wherein the input of the repetition operation is a portion of a bit sequence before the polar transform. The method also includes transmitting, by the first node, a signal including the output bit sequence to a second node.

    Abstract: Methods, apparatus, and systems that relate to Polarization-Adjusted Convolutional (PAC) coding with variable lengths are disclosed. In one example aspect, a method for digital communication includes determining, by a first node, an output bit sequence having E bits based on an input bit sequence having K bits. The output bit sequence is determined based on a transform that is applied prior to applying a Polar transform having a size of N. The transform is based on at least one index set that is a subset of a set of bit indices. The set of bit indices comprises all non-negative integers that are less than N and wherein K

    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.
