Abstract: A communications method and apparatus to implement radio frequency link sharing, improve radio frequency link utilization, and increase an uplink transmission rate. The method includes a terminal that receives first configuration information and second configuration information from a first network device. The first configuration information is used to indicate a first reference signal resource of a first antenna port, and the second configuration information is used to indicate a second reference signal resource of a second antenna port; or the first configuration information is used to indicate a third reference signal resource of a first quantity of antenna ports, and the second configuration information is used to indicate a fourth reference signal resource of a second quantity of antenna ports. The terminal sends a first reference signal based on the first configuration information and sends a second reference signal based on the second configuration information.

Abstract: This application relates to the field of wireless communications technologies, and provides an indication method, an indication determining method, a sending device, and a receiving device, to resolve a problem existing in a transmission technology solution in which a slot format is indicated by using single indication information. The indication determining method includes: receiving, by a receiving device in a first slot, first indication information and second indication information that are sent by a sending device; and determining, by the receiving device, that the first indication information indicates a slot format of the first slot, and that the second indication information indicates a slot format of a second slot, where the second slot is a slot after the first slot. This application is applicable to a scenario in which a slot format is configured for a slot.

Abstract: A control information processing method and system includes: receiving, by a first device, first control information sent by a network device; determining, by the first device based on first information, that the first control information is used to schedule a target device, where the target device is one of the first device and at least one second device. The first information is related to the first control information. When the target device is at least one second device, determining, by the first device, second control information based on resource information that is used for data transmission and that is included in the first control information, and sending the second control information to the target device, so that the target device transmits data based on the second control information. When the target device is the first device, transmitting, by the first device, data based on the first control information.

Abstract: A slot scheduling method and apparatus are provided. A determined slot includes a first slot, the first slot includes a first idle time, and a time interval between a start moment of the first idle time and a start moment of the first slot is less than or equal to a preset time interval threshold, or a time interval between a start moment of the first idle time and an end moment of at least one OFDM symbol that is in the first slot and that is used to transmit control signaling is less than or equal to a preset time interval threshold. No first service is scheduled in the first idle time, thereby providing a transmission opportunity for a second service. In addition, time-domain locations of uplink transmission and downlink transmission of the first service and the second service do not overlap.

Abstract: Embodiments of the present invention provide a paging determining method. The method includes: determining, by a network device, a first group to which a first terminal device paged on a first paging occasion belongs, where the first group belongs to the M groups; and sending, by the network device, control information based on the first group, where the control information is used to indicate paging information, and the paging information includes a device identifier of the first terminal device. Therefore, reduction of terminal device power consumption can be effectively supported.

Abstract: A method for power control during service transmission includes sending, by a user equipment (UE), a first signal on a first symbol set on a first carrier using a first transmit power, and sending, by the UE, a second signal on a second symbol set on a second carrier using a second transmit power. A time resource on the first symbol set overlaps with a time resource on the second symbol set. The first transmit power is a transmit power configured by a first base station. The second transmit power is less than or equal to a transmit power configured or indicated by a second base station.
