SIMPLIFIED SIGNALING FOR SMALL DATA TRANSMISSIONS |
摘要 |
A signaling procedure for establishing and terminating connections for small data transmissions (SDTs) by wireless devices. A wireless device sends an access request message to a serving wireless access node on a random access channel (RACH). The access request message includes an indication that the access is for a SDT. The access request message includes the amount of data that will be transmitted as part of the SDT. The wireless access node sends an assignment message to immediately assign radio resources to the wireless device without further signaling needed for the SDT to begin. When the wireless device begins the SDT, the first data block is coded and transmitted according to a first predetermined coding scheme. If there are any subsequent data blocks, the wireless device includes an information element in the header of the first data block to indicate the coding scheme for the subsequent data blocks.
