Abstract: A signal transmission method and an apparatus are provided. The method includes: A sending device generates a sequence of a demodulation reference signal, and maps the sequence of the demodulation reference signal to a time-frequency resource of the demodulation reference signal for sending. The demodulation reference signal is used to estimate a channel state of a first channel, and the first channel carries uplink data. The time-frequency resource includes frequency-domain resources corresponding to a first CDM group, and the frequency-domain resources corresponding to the first CDM group are non-contiguous and equally spaced.

Abstract: Embodiments of this application provide an information tranmission method, a communications apparatus, and a storage medium. A network device configures, for a terminal device by using higher layer signaling, a frequency domain resource size set that includes some frequency domain resource sizes supported by system bandwidth, so that the network device may allocate, to the terminal device, a frequency domain resource corresponding to a frequency domain resource size in the frequency domain resource size set. An RIV corresponding to the frequency domain resource is used to indicate the frequency domain resource. A quantity of bits occupied by the RIV is positively correlated with a quantity of schemes for the frequency domain resource that can be allocated by the network device to the terminal device.

Abstract: Example communication methods and apparatus are described. One example communication method includes generating a synchronization signal block (SSB) by an access network device, where the SSB includes a first physical broadcast channel (PBCH) and a second PBCH. The first PBCH carries time-frequency resource position information of first synchronization information, the second PBCH carries time-frequency resource position information of second synchronization information, and a time-frequency resource position of the first synchronization information is different from a time-frequency resource position of the second synchronization information. The access network device broadcasts the SSB. In embodiments of this application, the SSB may carry PBCHs corresponding to terminal devices of different bandwidth types and/or synchronization information of the terminal devices of different bandwidth types to satisfy processing requirements of the terminal devices of a plurality of bandwidth types.

Abstract: In a control information receiving method, a second device receives m control channels from a first device. Control information carried on the m control channels corresponds to a same hybrid automatic repeat request (HARQ) process and is consecutive control information of the HARQ process, control information carried on each of the m control channels includes false alarm indication information, and m is a positive integer greater than or equal to 2. The second device determines, based on a combined state of false alarm indication information carried on the m control channels, whether there is a false alarm in control information carried on at least one of the m control channels.

Abstract: A physical downlink control channel PDCCH transmission method and apparatus is provided. 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.
