However, in high-band communication, it is usually necessary to shorten the length of the symbol significantly, so that the length of the CP is also shortened accordingly, that is, in high-band communication, the above-mentioned transmission delay difference is much larger than that of the CP In this case, when transmitting data based on multiple beam pairs corresponding to the above two channels at the same time, the resulting transmission delay difference cannot be eliminated by the system, resulting in the data transmitted by multiple beam pairs cannot be reached at the receiving end sync request

An embodiment of the invention provides a data transmission synchronization method and a data transmission synchronization device, wherein the method and the device relate to the field of communication technology. According to the method and the device, information of a plurality of target wave beam pairs is determined from information of a plurality of wave beam pairs. The receiving power of each target wave beam pair is larger than or equal with a preset receiving power. Each wave beam pair comprises a first wave beam and a second wave beam. The first wave beam is generated by an antenna array at the base station side. The second wave beam is generated by an antenna array at a terminal side. Based on the information of the plurality of target wave beam pairs, the wave beam set to which each target wave beam pair belongs is determined. According to the wave beam set to which each target wave beam pair belongs, data are transmitted based on the plurality of target wave beam pairs. Namely in data transmission, data transmission is performed based on the plurality of target wave beam pairs according to the condition of the wave beam set to which each target wave beam pair that can be used for data transmission. A transmission time delay difference among the plurality of target wave beam pairs for data transmission can be eliminated by a system, thereby realizing a fact that the transmitted data satisfy the synchronization requirement at the receiving end.
Description
Technical field [0001] The present disclosure relates to the field of communication technology, and in particular, to a data transmission synchronization method and device. Background technique [0002] With the rapid development of communication technology, the spectrum resources of mobile communication networks are facing an increasingly scarce dilemma. With the increase of carrier frequency, high-frequency spectrum resources are becoming more and more abundant, and the communication technology field is introducing high-frequency spectrum resources into mobile communication networks. However, since the path loss increases with the increase of the carrier frequency, in the process of introducing high-frequency spectrum resources into the mobile communication network, beamforming technology of large-scale antennas is usually used to solve the problem of path loss. [0003] At present, in order to obtain the maximum system throughput, it is necessary to use beamforming technology a...
