Problems solved by technology

[0005] However, in the prior art, it is the network side that indicates to the UE through signaling how many logical channels to be used at the sender end are used to send the duplicated PDCP data packets, and which logical channels to be used at the sender end are used for data transmission. , leading to a relatively large signaling overhead in order to achieve a more flexible activation / deactivation control

Embodiment Construction

[0028] In the prior art, an activation / deactivation mechanism of two wireless data link duplication (Two-legs duplication) mode is supported. Specifically, for each RB configured with the replication function, a bit (bit) is used to indicate activation or deactivation of the replication function of the RB. The activation of the copy function can be used to instruct the PDCP to perform a copy operation, and both wireless data links perform data transmission; the deactivation of the copy function can be used to instruct the PDCP not to perform a copy operation, and only through the primary wireless data link (Primary leg) for data transmission.

[0029]However, for Multi-connectivity duplication, the radio bearer (Radio Bearer, RB) configured with the duplication function can be configured with more than two wireless data links (legs), then for one RB, how many It is unclear to use one bit to indicate the to-be-used logical channel of the sender to send the copied PDCP data pac...

Abstract

The invention discloses a method and device for uploading data by a user terminal, storage equipment and a user terminal. The method comprises the following steps: determining a measured value of a transmission quality parameter of each wireless data link of each RB configured with a PDCP replication function through a test; arranging the wireless data link of each RB according to the measured value of the transmission quality parameter of each wireless data link obtained by testing; selecting a preset number of wireless data links as standby wireless data links according to the arrangement sequence; and copying the preset number of PDCP data packets by the PDCP entity at the UE side, and sending the PDCP data packets through the standby wireless data link. According to the scheme of the invention, the signaling overhead is saved, and the transmission quality is improved, and the utilization efficiency of transmission resources is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for uploading data by a user terminal, a storage device, and a user terminal. Background technique [0002] With the continuous development of wireless technology, 3GPP introduced a new wireless technology (New Radio accesstechnology, NR) to cope with the demand for larger data volume and the demand for smaller transmission delay. This technology is also called the fifth generation of mobile communication. Technology 5G. [0003] In 5G, two new technologies are introduced, Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP) duplication (Duplication) function and sub-band (Band Width Part, BWP), wherein the sub-band is also called sub-bandwidth. [0004] In a specific implementation, the introduction of the PDCP replication function can improve the reliability of ultra-reliable low latency communication (UltraReliable Low...
