1. A transmission delay indication method, comprising:
determining, by a network device, a common transmission delay of at least one cell, wherein the common transmission delay is configured to determine a transmission timing between the network device and a terminal in the at least one cell; and
sending, by the network device, the common transmission delay to the terminal in the at least one cell;
further comprising:
receiving, by the network device, a timing advance (TA) of the terminal sent by the terminal; and
determining, by the network device, an offset according to the TA, and updating at least one of a first time interval and a second time interval configured to perform hybrid automatic retransmission reQuest (HARQ) transmission scheduling on the terminal,
wherein an updated first time interval is a sum of the first time interval configured to the terminal and the offset, and an updated second time interval is a sum of the second time interval configured to the terminal and the offset;
wherein the first time interval is a transmission time interval between a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH), and the second time interval is a transmission time interval between a physical downlink control channel (PDCCH) and a physical uplink shared channel (PUSCH).
