Abstract: The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.

Abstract: Embodiments of this application provide a scheduling request processing method and a terminal device. The scheduling request processing method includes: determining, by a terminal device, whether there is a regular BSR associated with a first logical channel that is triggered and has not been canceled; and if a regular BSR associated with the first logical channel is triggered and has not been canceled, and the terminal device has no uplink resource available to transmit data of the first logical channel, and a first timer of the terminal device is not running, triggering, by the terminal device, an SR, where the first timer is configured to delay transmission of the SR. According to the scheduling request processing method provided in the embodiments of this application, when the terminal device has no uplink resource available to transmit the data of the logical channel associated with the BSR, the SR is triggered to implement uplink resource scheduling, thereby satisfying a QoS requirement of the data carried on the logical channel.

Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. In one example, an embodiment technique includes polar encoding, with an encoder of the device, information bits and at least one parity bit using the polar code to obtain encoded data, and transmitting the encoded data to another device. The polar code comprises a plurality of sub-channels. The at least one parity bit being placed in at least one of the plurality of sub-channels. The at least one sub-channel is selected from the plurality of sub-channels based on a weight parameter.
