Abstract: Embodiments of the present application relate to the communications field and disclose a calibration method and a communications device, capable of compensating for measured amplitude and phase results. The method includes determining a position error of each of the N antenna groups, and then determining an actual position of the antenna group based on a target position of the antenna group and the position error of the antenna group. A phase compensation value and/or an amplitude compensation value of the antenna group are determined for a target probe of the second device based on the actual position of the antenna group. Based on the phase compensation value and/or the amplitude compensation value of the antenna group, compensating is performed for a phase result and/or an amplitude result that are/is obtained by the target probe of the second device by measuring a signal transmitted by the antenna group.

Abstract: A channel state information measurement method and apparatus and a network side device are described. The measurement method includes configuring, by a network side device, channel state information reference signal (CSI-RS) transmit information of M access points. The CSI-RS transmit information is used to indicate the M access points to periodically send a CSI-RS to a first user equipment at a preset interval. The preset interval is a time interval and/or a subband interval, and M is an integer greater than 1. The network side device obtains channel state information (CSI) corresponding to each of the M access points. The CSI corresponding to the access point includes first CSI, and the first CSI is information that is measured based on the CSI-RS corresponding to the access point and fed back by the first user equipment.

Abstract: A path computation method and a related device are disclosed. The method includes: a second network device receives path requirement information and a recomputation condition that are sent by a first network device; the second network device first obtains by means of computation a path meeting a requirement according to the path requirement information, and sends description information of the path meeting the requirement to the first network device; then the second network device constantly determines whether the recomputation condition is met; and when the recomputation condition is met, the second network device performs path recomputation, and sends description information of a path obtained by means of recomputation to the first network device. Therefore sensitivity for triggering path recomputation can be improved and a quantity of communication messages between network devices can be reduced.
