Problems solved by technology

In this process, the server uses the first downlink transmission weight of the first transmission point to determine the second downlink transmission weight of the second transmission point, so that when the electronic device receives the data stream sent by each transmission point in the coordination set, different data streams The receiving direction is orthogonal or approximately orthogonal, which solves the problem of excessive data flow interference between different transmission points when the electronic device receives the data stream, and realizes the purpose of the electronic device receiving data correctly

Embodiment Construction

[0077] The core of the CoMP technology is that when an electronic device is located in a cell boundary area, the electronic device can simultaneously receive signals from multiple transmission points. At the same time, the signal sent by the electronic device can also be simultaneously received by multiple transmission points. The CoMP technology can effectively improve the experience rate of users in the overlapping area of ​​cells. CoMP technology includes CJT technology and NCJT technology. In the NCJT technology, the transmission points in the cooperative set all send a physical downlink shared channel (PDSCH) to the electronic equipment in the cell boundary area, so that the electronic equipment obtains power gain and array gain. The transmission points in the cooperating set include a serving transmission point and at least one cooperating transmission point.

[0078] The further enhancement of CoMP (FeCoMP) technology is an NCJT technology. The basic idea of ​​the FeC...

Abstract

The embodiment of the invention provides a data sending method and device, equipment and a readable storage medium. The server determines a first transmission point from the cooperative set and determines a first downlink sending weight of the first transmission point; and then, the server determines a second downlink sending weight of the second transmission point based on the first downlink sending weight and sends the second downlink sending weight to the second transmission point. And when the second transmission point sends the data stream to the electronic equipment, the downlink sending weight corresponding to the data stream is determined from the matrix, and the data stream is weighted and then sent to the electronic equipment. In the process, the server determines the second downlink sending weight of the second transmission point by using the first downlink sending weight of the first transmission point, so that the receiving directions of different data streams are orthogonal or approximately orthogonal when the electronic equipment receives the data streams sent by the transmission points in the cooperation set; the problem that data flow interference between different transmission points is too large when the electronic equipment receives the data flow is solved, and the purpose that the electronic equipment correctly receives data is achieved.

Description

technical field [0001] The embodiments of the present application relate to the field of communications technologies, and in particular, to a data sending method, apparatus, device, and readable storage medium. Background technique [0002] The coordinated multiple point transmission / reception (CoMP) technology refers to a technology in which multiple transmission points separated geographically cooperate to transmit and serve one or more electronic devices. [0003] The joint transmission (JT) technology is a CoMP technology, and the JT technology is divided into a coherent joint transmission (CJT) technology and a non-coherent joint transmission (NCJT) technology. In the NCJT technology, the transmission points in the cooperative set all send downlink data to the electronic device, and the transmission points in the cooperative set include a serving transmission point and at least one cooperative transmission point. In the process of downlink data transmission, each trans...
