Problems solved by technology

For the Split bearer of EN-DC, when the LTE data has been sent to the base station, but the NR logical channel is not configured with SR resources, and the uplink transmission resources need to be obtained through random access, due to a certain delay in random access, the NR chain There is a delay in data transmission on the road, so the data received by the two links of the base station's LTE receiving link and NR receiving link are relatively large, resulting in the problem of data reception lag

Abstract

The present application provides a data transmission method and a terminal device, wherein the method includes: sending uplink data on the terminal device UE through a first link and a second link, and the first link is not configured with uplink scheduling request resources In the case where the UE does not acquire uplink transmission resources, the UE does not perform preprocessing of the uplink data, and sends the uplink data through the second link; when the UE acquires In the case of the uplink transmission resource, the UE determines whether to preprocess the uplink data according to the configured uplink transmission resource. Correspondingly, a corresponding terminal device is also provided. Implementing the present application can effectively reduce the discontinuity of data transmission.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data transmission method and terminal equipment. Background technique [0002] In the long term evolution (long term evolution, LTE) protocol, when a terminal device (user equipment, UE) needs to transmit data to a network device such as an evolved base station (evolution NodeB, eNB), the UE needs to first send a scheduling request to the eNB ( scheduling request, SR); after receiving the SR, the eNB returns an uplink scheduling grant (UL grant) to the UE; the UE sends a buffer status report (buffer status report, BSR) to the eNB, and the eNB can know the UE by receiving the BSR The size of the uplink data is sent; thus, the eNB sends an uplink scheduling grant to the UE, and the UE can know the allocated resource size through the uplink scheduling grant. The specific process can be as figure 1 shown, understandable, figure 1 The information sent by th...
