Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments of the present disclosure provide a communication method, an electronic device and a computer-readable storage medium. For an uplink service, the method comprises steps of: by a user equipment, determining a remaining PDB of a data packet in a buffer, and reporting related information of the remaining PDB to a base station, so as to assist the base station to perform proper uplink scheduling for the User Equipment according to the related information of the remaining PDB. Accordingly, the packet loss rate of data packets is reduced, and the transmission efficiency is improved.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method includes receiving configuration information of a first SSB by a UE and receiving, based on the configuration information, the first SSB for use in synchronization and/or measurement. The first SSB comprises fewer signals than a second SSB. In other words, the first SSB is simpler than the second SSB, so the first SSB is more energy-saving than the second SSB, so that the purpose of saving power on the base station side can be achieved.
