1. A method for improving early data transmission, EDT, the method comprising:
transmitting, during a first period, first transport block size, TBS, information indicating a first set of one or more EDT TBSs, the first set of EDT TBSs comprising a maximum EDT TBS;
after transmitting the first TBS information, obtaining EDT usage information;
based on the obtained EDT usage information, determining whether to transmit, during a second period, the first TBS information or second TBS information indicating a second set of one or more EDT TBSs, wherein the first set of EDT TBSs and the second set of EDT TBSs are different; and
transmitting, during the second period, the first TBS information or the second TBS information based on the determination, wherein
the EDT usage information comprises i) information indicating a number of EDTs performed during a time period and ii) for each EDT performed during the time period, information indicating the TBS used for the EDT.
