Abstract: A message transmission method and a device are used to accelerate a random access procedure. The method includes: receiving, by a terminal device, a repetition quantity of an uplink message from a network device, in response to determining that a reference signal receive power (RSRP) range of the terminal device is within an RSRP range corresponding to a signal coverage enhancement level 0, wherein the uplink message comprises a third message of a sequence of messages comprised in a random access attempt; calculating, by the terminal device, transmit power based on a power control parameter for the repetition quantity; and sending, by the terminal device, the uplink message to the network device based on the calculated transmit power.

Abstract: Embodiments of this application provide a method for receiving and sending a reference signal, an apparatus, and a system, so that a network device can correctly demodulate uplink data of different terminal devices of a same cell. This solution is applicable to a wireless communications system including a first cell. The first cell includes a plurality of terminal devices that can transmit uplink data on a same time-frequency resource. A first terminal device in the plurality of terminal devices determines an index of a first sequence based on a first parameter value, and generates a first reference signal based on the first sequence indicated by the index of the first sequence. Then, the first terminal device sends the first reference signal to the network device. The first parameter value is different from a parameter value corresponding to another terminal device in the plurality of terminal devices.

Abstract: Example reference signal sending methods and apparatus are described. In one example method, a terminal device detects whether a paging scheduling message exists in a PDCCH search space whose starting subframe is a subframe corresponding to a paging occasion (PO), and/or detects whether a wake-up signal (WUS) exists before a PO. A network device determines a time domain resource in first duration based on a quantity of paging occasions in a discontinuous reception period, where the time domain resource is a time domain resource in a time-frequency resource used to transmit a reference signal. The network device sends the reference signal to a terminal device on the time domain resource.
