Abstract: Embodiments of this application provide a random access response method and an apparatus. The method includes: RARs associated with one RO are transmitted based on groups, so that a transport block size of RAR data transmitted each time is reduced, and N bits in DCI format 1_0 of CRC are scrambled by using a RA-RNTI to indicate scheduling information of N RAR groups in a PDSCH. Alternatively, DCI format 1_0 of CRC is scrambled by using identifiers of RAR groups, to correspondingly schedule the RAR groups in the PDSCH. According to this application, a problem of a large transport block caused by a large quantity of RARs being transmitted in a PDSCH can be avoided, so that a modulation order or a bit rate is reduced, and demodulation performance of a terminal device is improved.

Abstract: A random access method and an apparatus. In one example: A terminal device receives a first wake-up signal, and then determines N random access channel occasions based on a correspondence between the first wake-up signal and the N random access channel occasions. The terminal device determines a first random access channel occasion in the N random access channel occasions, and sends a random access preamble on the first random access channel occasion. A network device uses, as a reception beam, a beam used to send the first wake-up signal, to receive the random access preamble sent by the terminal device.

Abstract: This application provides an uplink signal sending method, an apparatus, and a system, and generally relates to the field of communications technologies. The uplink signal sending method includes obtaining first indication information, and determining, based on the first indication information, whether to send an uplink signal on a supplementary uplink (SUL) or an uplink (UL). The first indication information is used to indicate a SUL available time, and the SUL available time is a time in which an uplink signal can be sent on an SUL carrier in a preset period. The method is applied to a procedure in which an uplink signal is sent by using an uplink carrier, to improve flexibility in an uplink signal sending process.

Abstract: This application relates to the field of communications technologies, and discloses a method and an apparatus for indicating a number of repetitions, so that a configuration of a number of repetitions of an SRS and/or a PUSCH is more adaptive to a channel change. The method includes: A network device sends DCI to a terminal device, where the DCI includes first indication information, and the first indication information indicates a number of repetitions of an SRS and/or a PUSCH. Because the DCI has a faster update process than RRC signaling, and overheads are smaller than those of the RRC signaling, the network side device may flexibly configure the number of repetitions of the SRS and/or the PUSCH by using the DCI, to better adapt to the channel change, and further improve a channel estimation capability and signal demodulation performance.

Abstract: A reference signal sending method, a reference signal receiving method, and an apparatus are provided. A first network device determines a first resource. The first network device generates a reference signal corresponding to the first resource. The reference signal includes M parts, and all of the M parts are the same. The first resource does not carry a cyclic postfix of the reference signal. Alternatively, the first resource carries a cyclic prefix of the reference signal and the cyclic prefix corresponding to the reference signal is located only at the start of the 1st part in the M parts. M is a positive integer. The first network device sends the reference signal to a second network device on the first resource.

Abstract: This application provides a switching method, it is determined that a switching delay of a first terminal device switching from a first bandwidth unit to a second bandwidth unit is a first delay, where the first delay is less than a second delay, and the second delay is a switching delay supported by a second terminal device. Alternatively, it is determined that a switching delay of a first terminal device switching from a first bandwidth unit to a second bandwidth unit is one of N delays, where the N delays are switching delays supported by the first terminal device, N is an integer greater than or equal to 2, and the N delays include a first delay. Therefore, switching between bandwidth units may be performed more quickly. In this case, the first terminal device may quickly perform dynamic data transmission within a large system bandwidth.
