Abstract: A data transmission method and an apparatus are provided. The method includes: A terminal device receives DCI from a network device, where the DCI is used to schedule downlink data and indicate a modulation scheme of the downlink data, the modulation scheme of the downlink data is a first modulation scheme or QPSK, and a modulation order corresponding to the first modulation scheme is greater than 2; and the terminal device receives the downlink data based on the modulation scheme. Based on the foregoing procedure, the network device indicates the modulation scheme of the downlink data by using the DCI, so that the terminal device receives the downlink data based on the modulation scheme indicated by the DCI. In this way, scheduling based on higher order modulation indicated by using the DCI is implemented.

Abstract: This application relates to the field of wireless communication technologies, and in particular, to a time control, an apparatus, and a system. This application provides a timer control method, including: When downlink control information indicates data transmission of N hybrid automatic repeat request HARQ processes and a terminal device is configured with the N HARQ processes, where N is an integer greater than or equal to 2, a discontinuous reception inactivity timer is not started or the discontinuous reception inactivity timer is stopped. This application reduces time required by the terminal device to monitor a downlink channel or downlink data through control by the timer, thereby reducing power consumption of the terminal device.

Abstract: A message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2a7+P·(nƒ mod k+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. 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.

Abstract: Example communication methods and apparatus are described. One example method includes determining a random access preamble by a terminal device, The random access preamble includes six symbol groups. The terminal device determines a frequency location of the random access preamble based on random access configuration information and a preset rule. A frequency hopping interval between a first symbol group and a second symbol group and a frequency hopping interval between a fifth symbol group and a sixth symbol group are equal and are first intervals. A frequency hopping interval between the second symbol group and a third symbol group and a frequency hopping interval between a fourth symbol group and the fifth symbol group are equal and are second intervals. A frequency hopping interval between the third symbol group and the fourth symbol group is a third interval. The random access preamble is sent based on the frequency location.
