摘要： Embodiments of the present invention provide a resource scheduling method, a terminal device, and a network device. In the method, after receiving a configuration message of a network device, a terminal device obtains, based on the configuration message, first resource configuration information used to send a scheduling request, where the first resource configuration information includes information used to indicate a coverage enhancement level. Further, the terminal device sends a scheduling request to the network device on a first resource indicated by the first resource configuration information, where the scheduling request is used to request an uplink channel resource from the network device, and the terminal device performs no random access process when sending the scheduling request. In the method, the terminal device sends the scheduling request to the network device on the first resource indicated by the first resource configuration information that is in the configuration message, that is, notifies the network device that the terminal device needs to send data, and then directly sends uplink data without performing a random access process, thereby reducing power consumption and delay of the terminal device.

摘要： A message transmission method and device relating to the field of communications technologies is disclosed, so as to improve an anti-interference capability in message transmission. The method includes: generating, by a base station, a scrambling code according to a first time parameter; then scrambling a system message according to the scrambling code; and finally sending the scrambled system message to a terminal on a physical broadcast channel. In this technical solution, because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

摘要： Embodiments of this application disclose a communication method and apparatus. According to the method, a terminal device determines a random access resource, where a quantity of frequency domain resources of the random access resource is greater than a quantity of frequency domain resources of a maximum bandwidth of the terminal device, and sends a physical random access channel PRACH on the random access resource. Because the determined random access resource can meet a resource requirement for PRACH transmission, communication between the terminal device and an access network device can be ensured.
