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: A communication method includes determining, by a network device, a first signal. The first signal includes a primary synchronization signal PSS, a secondary synchronization signal SSS, and a first physical broadcast channel PBCH. A frequency domain bandwidth occupied by the PSS, the SSS, and the first PBCH is less than 240 subcarriers. The PSS, the SSS, and the first PBCH are mapped to different time-domain symbols. The method also includes sending, by the network device, the first signal.

Abstract: A communication method and apparatus are provided. A terminal device determines a first transmission time period and a second transmission time period, where the first transmission time period includes X1 time units, the second transmission time period includes X2 time units, and the first transmission time period does not overlap the second transmission time period. The terminal device sends a first reference signal in the first transmission time period and a first uplink signal in the second transmission time period, where the first uplink signal includes at least one of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), or a demodulation reference signal (DMRS). Therefore, the terminal device may additionally send the first reference signal, to improve uplink channel estimation performance of a network device. This improves coverage performance of a communication system.

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: Various embodiments provide a communication method, a communications apparatus, and a computer-readable storage medium. In those embodiments, a first transmit power can be determined for transmitting first information in a first time unit on a first carrier and a second transmit power can be determined for transmitting second information in a second time unit on a second carrier. A third transmit power can be determined for transmitting the second information in a first time period and transmitting the second information in a second time period using the second transmit power or the third transmit power. The second information can be sent in the first time period using the third transmit power. In those embodiments, a sum of powers used by a terminal device to transmit two uplink carriers in a same time period does not exceed a maximum transmit power of the terminal device.
