Abstract: The present invention discloses a pilot sequence transmission method and apparatus. A terminal device determines a first pilot number, determines a first pilot sequence and a second pilot sequence according to the first pilot number, respectively maps the first pilot sequence and the second pilot sequence to a first OFDM symbol and a second OFDM symbol of a grant free transmission resource, and sends the first pilot sequence and the second pilot sequence by using the first OFDM symbol and the second OFDM symbol. Therefore, a network device can determine activeness of the terminal device by detecting the first pilot sequence, and can detect only the second pilot sequence corresponding to the first pilot sequence, and does not need to detect all possible second pilot sequences, so that a quantity of detected pilots can be significantly reduced, and pilot detection complexity is reduced.

Abstract: This application provides a random access method and an apparatus. The random access method includes: User equipment sends a random access message of a first-type random access procedure to a network device. The random access message of the first-type random access procedure includes a random access preamble and uplink data. The user equipment starts a first time window after the end of the transmission of the random access preamble, and detects first downlink control information (DCI) and second DCI within the first time window. The first DCI is used to schedule a first physical downlink shared channel PDSCH for carrying a first response message to the random access preamble, and the second DCI is used to schedule a second PDSCH for carrying a second response message to the random access message.

Abstract: A reference signal indication method includes receiving a plurality of reference signals, and sending at least one codeword on a first time-frequency resource. The at least one codeword includes a first codeword. The first codeword corresponds to a first reference signal in N reference signals of the plurality of reference signals. The first reference signal is a selected reference signal. The N reference signals are a subset of the plurality of reference signals, and N is a positive integer.

CPC classification number: H04W52/146 , H04W52/367
Abstract: This application provides example uplink transmit power determining methods and example terminal devices. One example method includes receiving, by a terminal device, a broadcast message that is sent by an access network device and that carries first power control information, where the first power control information is used to determine a modulation and coding scheme (MCS) compensation factor. The terminal device can then determine the MCS compensation factor based on the first power control information. The terminal device can then determine a first candidate uplink transmit power based on the MCS compensation factor. The terminal device can then determine a smaller value in the first candidate uplink transmit power and a second candidate uplink transmit power as a physical uplink shared channel (PUSCH) transmit power. The terminal device can then send PUSCH information in a random access message based on the PUSCH transmit power.
