Publication number: 20240276528Abstract: This application relates to a communication method and device. A first terminal device receives at least one message for reserving a resource, and the first terminal device determines, from S resources based on the at least one message, M resources whose signal strengths do not meet a first signal strength threshold. The first terminal device adjusts the first signal strength threshold if M does not meet a first resource quantity or S-M does not meet a first resource quantity. The first terminal device sends a first message to a second terminal device, where the first message indicates a resource determined based on an adjusted signal strength threshold, and the adjusted signal strength threshold enables M or S-M to meet the first resource quantity.Type: ApplicationFiled: April 24, 2024Publication date: August 15, 2024Inventors: Yun Liu, Lixia Xue, Yu Cai
