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

Embodiments of the present disclosure relate to the technical field of communications. Provided are a method and apparatus for synchronously transmitting data. The present disclosure comprises: determining information about multiple target wave beam pairs from information about multiple wave beam pairs, the reception power of each target wave beam pair being greater than or equal to a preset reception power, each wave beam pair comprising a first wave beam and a second wave beam, the first wave beam being generated by an antenna array on a base station side, and the second wave beam being generated by an antenna array on a terminal side; determining, according to the information about the multiple target wave beam pairs, wave beam sets to which the target wave beam pairs belong; and transmitting data according to the multiple target wave beam pairs and the wave beam sets to which the target wave beam pairs belong. That is, in data transmission, data is transmitted according to the multiple target wave beam pairs and the condition of the wave beam sets to which the target wave beam pairs capable of being used for data transmission belong. A transmission time delay difference among the multiple target wave beam pairs used for data transmission can be eliminated by a system, and accordingly the transmitted data satisfies synchronization requirements at the reception end.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, 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 the carrier frequency, the spectrum resources of the high frequency band become more and more abundant, and the spectrum resources of the high frequency band are being introduced into the mobile communication network in the field of communication technology. 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, the 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 th...
