Abstract: Provided are a capability information feedback method and apparatus, and a channel state information feedback method and apparatus. The capability information feedback method comprises: transmitting, by a first communication node, capability information to a second communication node, where the capability information is used for indicating a capability of the first communication node; and receiving, by the first communication node, parameter signaling which is transmitted by the second communication node and corresponds to the capability of the first communication node. Through the method, the first communication node feeds the capability information supported by the first communication node back to the second communication node so that the second communication node can perform scheduling based on the capability of the first communication node, thereby reducing the system overhead and improving the system performance.

Abstract: Techniques are described for performing timing-based positioning methods including measuring and/or reporting timing errors. An example technique includes, determining, by a communication node, measurement information that comprises a set of measurement results and a set of timing delays, wherein the set of measurement results include a first set of time values when positioning signals are sent or received by a processor of the communication node, and wherein the set of timing delays includes a second set of time values, each of the second set of time values is a difference between when a positioning signal is sent or received by the processor of the communication node and when the positioning signal is respectively transmitted or received by an antenna of the communication node; and transmitting, by the communication node, the set of measurement results and the set of timing delays to a second communication node.

Abstract: Provided are an information feedback method and device, an information receiving method and device, and a storage medium. The information feedback method includes the following. Configuration information from a first communication node is received. Precoding matrix information is determined according to the configuration information, where a target frequency band of the precoding matrix information is determined through indication information of a precoding matrix information subband, and the precoding matrix information subband is determined according to the configuration information. The precoding matrix information is fed back to the first communication node.
