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 discloses a signal sending method, a signal receiving method, and a communication apparatus. The method includes: A network device determines a first SSB and a second SSB, sends the first SSB in a first BWP, and sends the second SSB in a second BWP. Transmit power of the first SSB is different from transmit power of the second SSB. The first BWP may be considered as a BWP of a first-type terminal device, and the second BWP may be considered as a BWP of a second-type terminal device. The network device may send the first SSB in the first BWP, and send the second SSB in the second BWP. The second-type terminal device obtains an SSB from the network device without switching from the second BWP to the first BWP, to reduce a quantity of BWP switching times, so as to reduce power consumption.

Abstract: An apparatus includes one or more processors and a memory having instructions stored thereon that, when executed by the one or more processors, cause the apparatus to receive a first wake-up signal. The first wake-up signal is one of K wake-up signals, K is an integer greater than or equal to 1, and the K wake-up signals are quasi co-located with K synchronization signal blocks (SSBs), K channel state information-reference signals (CSI-RSs), or K demodulation reference signals (DMRSs). The apparatus is also caused to determine M paging occasions. There is a correspondence between the K wake-up signals and the M paging occasions, and M is an integer greater than or equal to 1. The apparatus is further caused to receive, on the M paging occasions, downlink control information (DCI) used for paging.

Abstract: This application provides a physical downlink control channel PDCCH transmission method and an apparatus. The method includes: A network device sends first indication information to a terminal device, where the first indication information may include configuration information of a PDCCH, the configuration information of the PDCCH is used to indicate at least one repeated transmission configuration manner, which includes a first repeated transmission configuration manner. The repeated transmission configuration manner includes at least one of a quantity of repetitions of the PDCCH and an aggregation level that is of the PDCCH and that corresponds to the quantity of repetitions. The network device may send the PDCCH to the terminal device based on the first repeated transmission configuration manner. According to this method, a sending effect of a PDCCH at a higher aggregation level can be implemented through repeated sending of a plurality of PDCCHs at lower aggregation levels.
