Abstract: A short-range communication method and apparatus are applied to the field of short-range communication, particularly related to scenarios such as smart driving, smart manufacturing, and can establish time-frequency synchronization between nodes in an entire network. The method includes: A first node receives at least one piece of node information from at least one node; and the first node controls the first node to establish time-frequency synchronization with a second node that is in the at least one node and that belongs to a second synchronization area, where node information from the second node includes synchronization information of the second synchronization area, and the synchronization information indicates at least one of a node identifier, a synchronization status, or a synchronization direction between nodes in the second synchronization area. This solution may be further used to improve an autonomous driving or advanced driver assistance system ADAS capability.

Abstract: An information processing method, a terminal device, and a network device are provided. In one method, a first bit in downlink control information includes two bits, a bit status of the first bit may belong to a first state set or may be a second state, and a terminal device may perform multi-TB scheduling or single-TB scheduling based on the first bit. When the bit status of the first bit belongs to the first state set, the first state set is {01, 10, 11}, N=4, and the downlink control information includes a first field, the bit status of the first bit can be used to determine a quantity L of TBs scheduled by the downlink control information, and a bit status of five bits of the first field can be used to determine HARQ process numbers of the L TBs and NDI information of the L TBs.
