Abstract: Example random access methods and apparatus are described. In one example method, a terminal device receives a system message that is sent by a network device on a first downlink carrier. The system message includes first information for performing random access on a first uplink carrier and second information for performing random access on a second uplink carrier. A frequency of the first uplink carrier is higher than a frequency of the second uplink carrier, and a frequency of the first downlink carrier is the same as the frequency of the first uplink carrier. The terminal device sends a random access request message on the first uplink carrier or on the second uplink carrier, and receives a random access response message that is sent by the network device on the first downlink carrier.

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: Embodiments of this application provide a resource indication method and a communication device. The resource indication method includes: A first communication device receives first information sent by a second communication device, where the first information is used to indicate a first resource pattern and indicate a reserved resource determined by using the first resource pattern, the first resource pattern is used to determine a position corresponding to each of N resource sets, and N is a positive integer greater than or equal to 1. The first communication device determines reserved resource based on the positions corresponding to the N resource sets and indicated by the first resource pattern, where the reserved resource is a resource unavailable to the first communication device. The first communication device determines not to transmit a signal by using the reserved resource.

Abstract: A communication method and apparatus are provided. The method includes: 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 PUSCH, a PUCCH, or a 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.
