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.

Abstract: Example communication methods and apparatus are described. One example method includes receiving configuration information of a first control resource set by a terminal device, where the configuration information of the first control resource set includes mapping manner information of the first control resource set. The terminal device determines a mapping manner between a control channel element (CCE) and resource element groups (REGs) in the first control resource set based on the mapping manner information of the first control resource set, wherein a REG in the first control resource set occupies one symbol in time domain and occupies one resource block RB in frequency domain.

Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.
