Abstract: 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.

Abstract: Embodiments of the present disclosure disclose a method for determining a frequency resource, and an apparatus. The method includes: first determining, by user equipment (UE), a power headroom report; and subsequently sending, by the UE, the power headroom report (PHR) to a base station in a random access process, where the power headroom report may be carried by a related information segment of message 3 (Message 3) sent by the UE to the base station. According to the solutions provided in the present disclosure, a base station can obtain, in a timely manner, a basis for performing scheduling configuration when UE performs current uplink data transmission, and can more accurately configure power control and scheduling information for the UE. This avoids allocating the UE a channel that exceeds an uplink transmission capability of the UE, and thereby avoids an uplink bandwidth waste.

Abstract: Embodiments of the present invention disclose a downlink control information (DCI) transmission method, a network device, and user equipment. The method includes the following steps: A network device transmits DCI in a first DCI format; when the DCI is used to schedule a physical downlink shared channel (PDSCH) carrying a multicast traffic channel, the network device indicates, by using a first radio network temporary identifier (RNTI), that the DCI is used to schedule the PDSCH carrying the multicast traffic channel, and that first information is indicated in the DCI and second information is not indicated in the DCI; and when the DCI is used to schedule a user equipment-specific (UE-specific) PDSCH, the network device indicates, by using a second RNTI, that the DCI is used to schedule the UE-specific PDSCH, and that the first information is not indicated in the DCI and the second information is indicated in the DCI.
