Title
(EN) Data transmission method and device and storage medium
(ZH) 一种数据传输方法、装置及存储介质
Abstract
(EN) The embodiment of the invention provides a data transmission method and device and a storage medium; the method comprises the steps: determining a target RO, a target leader sequence and a target PO group according to the data size of to-be-transmitted data and the mapping relation among the RO, the leader sequence and the PO group; transmitting the target leader sequence on a target RO, and transmitting data to be transmitted on a resource block in a target PO group, the number of bits for bearing the data in the target PO group satisfying the data volume of the data to be transmitted. In the embodiment of the invention, the network equipment can support multiple transmission blocks to be in a non-connection state at the same time in a random access process, and the terminal can flexibly select uplink transmission resources in the MSGA according to the size of own data service and channel conditions; according to the method, more flexibility is provided for random access resource allocation of the network equipment, and the utilization efficiency of network resources is improved. Meanwhile, various data transmission quantities of the terminal equipment are supported in the non-connection state, and different service requirements of the terminal are met.
(ZH) 本发明实施例提供一种数据传输方法、装置及存储介质,该方法包括根据待传输数据的数据量,以及RO、前导序列和PO组之间的映射关系,确定目标RO、目标前导序列和目标PO组;在目标RO上传输所述目标前导序列,在目标PO组中的资源块上传输待传输数据;目标PO组中用于承载数据的比特的数量满足待传输数据的数据量。本发明实施例中,网络设备可以实现在随机接入过程中支持多种传输块同时在非连接状态,终端可以根据自身数据业务大小以及信道条件灵活的选择MSGA中上行发送资源;为网络设备随机接入资源分配提供了更多的灵活性,同时提升网络资源利用效率同时在非连接态,支持终端设备多种数据传输量,满足终端不同业务需求。
