Abstract: Embodiments of this application provide a sounding reference signal (SRS) transmission method, apparatus, and system, so as to implement sounding reference signal BP-based switching. The method includes: determining that a transmission conflict occurs between a sounding reference signal (SRS) on a first bandwidth part (BP) and an SRS on a second BP; and discarding the SRS on the first BP, where a priority of the SRS on the first BP is lower than a priority of the SRS on the second BP.

Abstract: An access network device sends, to a terminal device, indication information indicating to shut down one or more carrier groups, where each carrier group includes one or more carriers, so that the terminal device shuts down carriers in M carrier groups based on the indication information. This can reduce a quantity of operating carriers, thereby reducing power consumption.

Abstract: The present invention relates to the field of wireless communications technologies, and provides a method for transmitting a carrier, a base station, user equipment, and a system. The method discloses: sending, by a base station, a second carrier, where the second carrier at least partially shares a same resource area with a first carrier, the resource area includes a plurality of resource elements, and the first carrier and the second carrier occupy different resource elements; and sending, by the base station, blank resource element indication information to user equipment that receives the second carrier, where the blank resource element indication information is used to indicate a position of a resource element occupied by the first carrier in the shared resource area. According to the solutions provided in the embodiments, a resource utilization rate of a communications system is improved, and interference between carriers is avoided.

Abstract: Embodiments provide a communication method, a network device, and a terminal device. Under the method, a network device can send SRS configuration information of a first transmission resource and of a second transmission resource to a terminal device. The first transmission resource is a switching source carrier or bandwidth part. The second transmission resource is a switching destination carrier or bandwidth part. The SRS configuration information of the first and second transmission resource includes a first OFDM symbol set and a second OFDM symbol set respectively. Some and all symbols in the first set and second set may be used by the terminal device to send an SRS on the first and second transmission resource respectively. In various embodiments, the network device configures one or more symbols for the terminal device to transmit an SRS, so that high-frequency channel measurement can be better supported.

Abstract: Embodiments of the present application provide a data transmission method. The method includes: sending, by user equipment, uplink data to a base station by using an uplink user equipment relay; and receiving, by the user equipment, downlink data from the base station, or receiving, by the user equipment, downlink data from the base station by using a downlink user equipment relay. Uplink transmission and downlink transmission are separately performed in different transmission paths, so as to reduce impact of a fault of a user equipment relay on a network, and improve network reliability.
