Methods, Devices, And Medium For Communication

Abstract: Example embodiments of the present disclosure relate to small data transmission. Although the present disclosure, the stored data is not taken into consideration when calculating data volume for small data transmission, and thus correct data volume value can be obtained thereby. Further, the terminal device may obtain information about volume of new data before calculating data volume for small data transmission. In addition, during small data transmission, the reported buffer status report may indicate an actual state of the remaining small data transmission data. Further, when the terminal device fails to transmit small data transmission data via 4-step random access procedure, the terminal device may fall back to 4-step random access small data transmission properly.
