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 having K bits, wherein the output bit sequence is determined by performing a polar transform with H components and a pre-transform; wherein the polar transform is based on H polar matrices G(N0), G(N1), . . . , G(NH−0), wherein E, K, H are integers greater than 1, wherein a polar matrix G(N0) is of size Ni. The method also includes transmitting, by the first node, a signal including the output bit sequence to a second node.

Abstract: This disclosure relates to methods and devices for configuring guard subcarriers in transmission subbands to reduce interband interference in a wireless communication network. In one implementation, the method may include determining that a first subcarrier spacing for a first radio frequency transmission band is less than a second subcarrier spacing for a second radio frequency transmission band, and the first radio frequency transmission band is close to the second radio frequency transmission band in frequency spectrum. The method may further include configuring a subcarrier of the first radio frequency transmission band as a guard subcarrier carrying dummy data when the first radio frequency transmission band and the second radio frequency transmission band are simultaneously used to transmit data loads.
