Abstract: An information transmission method and a device, where the method includes sending, by a first device, a first signal to a second device, where the first signal enables the second device to determine, according to the first signal, a resource location at which the first device sends a second signal or a control signal of the second signal, and send a first signal of the second device at a resource location different from the determined resource location, and sending, by the first device, the second signal or the control signal of the second signal to the second device at the resource location. Therefore, a conflict between the first signal sent by the second device and the second signal sent by the first device can be avoided, so that the second device can quickly and accurately receive the second signal sent by the first device.

Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.
