Problems solved by technology

[0004] One problem with this solution is that since the logical channel is bound to the carrier to which it is mapped, if the carrier bound to the logical channel is congested or has a link problem, the logical channel will not be able to transmit data

Abstract

The invention relates to a data transmission method which comprises the following steps: receiving first information sent by a base station; creating a bearing separation; and the buffer status report comprising the buffer information of the first logical channel and the second logical channel is transmitted to the base station., receiving second information returned by the base station; acquiring first information and or the constraint information in the second information, and generating a constraint relation according to the constraint information, wherein, the constraint relation is used for limiting the first logical channel and the second logical channel to be mapped to different carriers respectively; and the resources of different carriers are respectively distributed for the first logical channel and the second logical channel according to the distribution information and the constraint relation. According to embodiments of the present disclosure, due to unbound logical channels and carriers for which resources are allocated, only the second logical channel allocation resources are defined for the first logical channel through different carriers., and therefore when it is detected that a certain carrier has congestion or a link and the like, logical channels mapped to the carriers can be adjusted to be mapped to other carriers.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method, a data transmission device, a data receiving method, a data receiving device and electronic equipment. Background technique [0002] At present, in order to solve the reliability problem of data packet and signaling packet transmission, a scheme of duplicating data packets and signaling packets at the PDCP (packet data convergence protocol, data packet convergence protocol) layer on the user equipment side is mainly adopted. However, since the PDCP layer is located at the top layer of the protocol stack on the side of the wireless device, the replicated packet of the PDCP layer cannot be guaranteed to be sent through two carriers at the bottom layer, which may cause the signal quality on the same carrier to be poor, and the replicated If the packet is still sent on the carrier, the probability of its successful delivery will be v...
