Data scheduling method and device and computer readable storage medium

Abstract

The embodiment of the invention relates to the field of wireless communication, and discloses a data scheduling method and device and a computer readable storage medium, and the data scheduling method comprises the steps: obtaining the number of first feature signal ports and the number of second feature signal ports of a super cell; configuring a first channel state message reference signal and a second channel state message reference signal for user equipment accessing the super cell; and determining whether to activate the second channel state message reference signal according to the maximum configurable port number of a sub-cell to which the user equipment belongs, and when determining to activate the second channel state message reference signal, triggering the user equipment to report a second channel characteristic parameter through the second channel state message reference signal, and performing downlink PDSCH scheduling on the user equipment according to the second channel characteristic parameter. According to the data scheduling method and device and the computer readable storage medium provided by the invention, a base station side can perform accurate scheduling, so that the data throughput of the super cell is maximized.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and in particular, to a data scheduling method, device, and computer-readable storage medium. Background technique [0002] The super cell is composed of multiple CPs (Cell-Portions, regular cells), and each CP shares the resources of the super cell, including PCI (Physical-layer cell identities), time domain resources, frequency domain resources, and so on. In actual networking, there are often scenarios where CPs in a super cell have two antenna configurations and support different numbers of transmit antenna ports. That is, some CPs in a super cell have M antennas and support PM ports for downlink transmission, while some CPs in a super cell have M antennas and support PM ports for downlink transmission. There are N antennas and support the downlink transmission of PN ports, but the terminal cannot recognize this situation, so the base station usually only configures...

In actual networking, there are often scenarios where CPs in a super cell have two antenna configurations and support different numbers of transmit antenna ports. That is, some CPs in a super cell have M antennas and support PM ports for downlink transmission, while some CPs in a super cell have M antennas and support PM ports for downlink transmission. There are N antennas and support the downlink transmission of PN ports, but the terminal cannot recognize this situation, so the base station usually only configures a set of periodic CSI-RS (Channel-state information reference signal, channel state Message reference signal) is used for measurement feedback of user equipment's CQI (Channel quality indicator, channel quality indicator), PMI (Precodingmatrix indicator, precoding matrix indicator) and RI (Rank indicator, rank indicator)

[0003] The inventors have found that there are at least the following problems in the related art: if the number of configured CSI-RS ports is equal to the smaller value of PM and PN, the RI reported by the user equipment (User Equipment, user equipment) is limited by the PM and PN The smaller value of , the scheduling may lose the number of layers of user equipment, thereby losing the flow of user equipment; if the configured number of CSI-RS ports is equal to the larger value of PM and PN, then if the user equipment is in PM and PN When the CP with a smaller value is within the coverage area, the reported RI may be greater than the smaller value of PM and PN, then the reported value obtained by the base station side is inaccurate. Scheduling, thus losing the flow of user equipment
