Abstract: Embodiments of this application disclose a path fault detection method and apparatus, a related device, and a storage medium, and belong to the field of communication technologies. In embodiments of this application, a return path is determined according to a forward path. In a path fault detection process, the return path through which a fault detection packet fed back by a tail node to a head node passes includes the forward path. In this way, if the head node receives the fault detection packet fed back by the tail node, it indicates that the forward path is not faulty.

Abstract: A method and an apparatus is provided for sending and receiving uplink control information, including: receiving, by a terminal, a first PDCCH and a second PDCCH that are sent by a network device, where the first PDCCH and the second PDCCH are transmitted in a same time unit, the first PDCCH indicates a first PUCCH resource and is used to schedule a first downlink TB, and the second PDCCH indicates a second PUCCH resource and is used to schedule a second downlink TB; and sending, by the terminal on the first PUCCH resource, response information of the first downlink TB and response information of the second downlink TB to the network device. When one PUCCH fails to be received, the network device may obtain the response information of the two downlink TBs from the other PUCCH, thereby ensuring that HARQ feedback information of the downlink TBs is correctly received.

Abstract: Various embodiments provide a method for receiving reference signal and a method for sending a reference signal. In those embodiments, a terminal device can determine a location of a resource element to which a reference signal is mapped. The terminal device can determine a reference signal sequence corresponding to the resource element. The index of each element in the reference signal sequence is determined based on a resource block index of a resource block corresponding to the resource element, a quantity of resource elements that carry the reference signal in the resource block, a resource block offset, or an inter-symbol offset. The terminal device can receive the reference signal by using the resource element, and performing channel estimation or channel sounding based on the received reference signal and the reference signal sequence. Therefore, the terminal device can complete channel estimation without learning of a system bandwidth.
