Abstract: This application provides a transmission method and apparatus. The method includes: A terminal sends a random access preamble to a base station at a first transmit power, and sends a PUSCH to the base station at a second transmit power, where power deviation between the first transmit power and the second transmit power is indicated to the base station by indication information; and the terminal receives a random access response or a contention resolution message from the base station. Implementing this application can improve an existing random access procedure, so that the random access procedure is adapted to scenario requirements such as low delay, high reliability, and large-scale terminal access.

Abstract: This application relates to the mobile communications field, and in particular, to a technology for obtaining a reference signal in a wireless communications system. In one example method for obtaining a reference signal, a terminal device obtains position offset information. The terminal device obtains a first sequence based on the position offset information. The terminal device demodulates, by using the first sequence, a control channel signal carried in a control channel resource set to obtain downlink control information.

Abstract: Embodiments provide resource scheduling method, user equipment, and an access network device. The method includes: receiving, by user equipment over a first control channel, first indication information corresponding to a transport block, where time-frequency resources occupied by a data channel in which the transport block is located include a first resource set and a second resource set, and the first indication information is used to indicate the first resource set and a time-frequency resource of a second control channel; receiving, by the user equipment, second indication information over the second control channel, where the second indication information is used to indicate the second resource set; and determining, by the user equipment, the transport block based on the first resource set and the second resource set. This can reduce control signaling overheads and improve flexibility of control channel resource scheduling.
