摘要： This application provides a channel transmission method, apparatus, and system for NB-IoT. An NB-IoT base station determines, based on the frequency hopping information, a time-frequency resource location of the channel after frequency hopping, and performs channel transmission with an NB-IoT terminal on a time-frequency resource corresponding to the time-frequency resource location, so that the frequency hopping is introduced into the NB-IoT, thereby increasing a gain of frequency diversity through the frequency hopping.

摘要： This application provides an information processing method and a communications device. This implements monitoring on a first time window by a first communications device, and avoids a problem that a time window cannot be monitored. An information processing method includes: A first communications device receives first information from a second communications device. The first communications device determines, based on the first information, that a start location of a first time window is a K1 th time unit after a start location of a first resource or the start location of the first time window is a K2 th time unit after an end location of the first resource. The first resource is a resource used by the first communications device to transmit data, and K1 and K2 are positive integers. The first communications device monitors, based on the determined start location of the first time window, control information sent by the second communications device.
