Abstract: This application provides a communication method and a communication apparatus. In the method, M amplitude shift keying modulation symbols included in a first signal sent by a signal sending device are the same as M amplitude shift keying modulation symbols included in a second signal. In addition, bandwidth occupied by a first frequency domain signal of the first signal in frequency domain is half of that occupied by a second frequency domain signal of the second signal in frequency domain. In addition, the first signal is one OFDM symbol in time domain, and duration of the M amplitude shift keying modulation symbols carried by the first signal is the same as that of the M amplitude shift keying modulation symbols carried by the second signal.

Abstract: A method and an apparatus for receiving a wake-up signal sequence are disclosed. The method includes: determining a first parameter corresponding to a first wake-up signal (WUS) resource, and the first WUS resource is associated with a paging occasion (PO), generating a first WUS sequence based on the first parameter, monitoring the first WUS sequence on the first WUS resource, and detecting a physical downlink control channel at the PO in response to detection of the first WUS sequence on the first WUS resource.

Abstract: A message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2α7+P·(nfmodk+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

Abstract: A channel quality measurement method and apparatus are described. The method can include a network device sending configuration information to a terminal device. The configuration information configures a downlink carrier set. The terminal device determines a first downlink carrier from the downlink carrier set. The terminal device sends a random access process message 3 (Msg3) to the network device. The random access process message 3 includes first information. The first information includes information indicating channel quality of the first downlink carrier. The channel quality provides information about a first repetition level to the network device. The first repetition level is a minimum repetition level required when transmission performed on a downlink channel based on a preset transmission parameter meets a preset block error rate.

Abstract: Embodiments provide for a channel quality reporting method, an apparatus, and a system. A terminal device determines a first index corresponding to the channel quality, and sends the first index and indication information to a network device. The first index occupies a first field, the first index is an index in an index set corresponding to a case in which a repetition number of a physical downlink control channel and/or a physical downlink data channel is a first repetition number, and the indication information indicates that the first field is occupied by an index corresponding to the first repetition number.

Abstract: This application provides a communication method and apparatus, to resolve a problem of receiving and sending an SSB in a bandwidth-limited network such as a dedicated network. The method includes: generating a sequence corresponding to a first synchronization signal/physical broadcast channel block (SSB), and determining a first SSB frequency location; and sending, based on the determined first SSB frequency location, the sequence corresponding to the first SSB. The first SSB frequency location is associated with bandwidth of a network in which the first SSB is located, or the first SSB frequency location is related to at least one of a lowest frequency of a network or a highest frequency of the network.
