Abstract
An electronic device, a method applied to an electronic device, and a data processing device. The electronic device includes: a processing circuit configured to allow a cell to implement data transmission by using at least a portion of a time resource corresponding to an unused channel state information reference signal (CSI-RS) port, wherein the CSI-RS port is from a CSR-RS configuration different from a CSI-RS configuration of the cell.
Claims9
An electronic device operating in a first cell in accordance with a first channel state information-reference signal (CSI-RS) configuration, comprising:
- processing circuitry, configured to:
- determine a usage status of CSI-RS ports of at least one cell adjacent to the first cell;
- determine, based on the usage status, time-frequency resources corresponding to one or more idle CSI-RS ports of a CSI-RS configuration of the at least one cell adjacent to the first cell, the CSI-RS configuration of the at least one cell adjacent to the first cell being different from the first CSI-RS configuration;
- and
- enable the first cell to use at least a portion of the time-frequency resources corresponding to the one or more idle CSI-RS ports of the CSI-RS configuration of the at least one cell adjacent to the first cell,
- wherein the processing circuitry is further configured to enable the first cell to use at least the portion of the time-frequency resources corresponding to the one or more idle CSI-RS ports of the CSI-RS configuration of the at least one cell adjacent to the first cell when a first predetermined condition is met,
- wherein the first predetermined condition is that a total number of time-frequency resources of the portion of the time-frequency resources corresponding to the one or more idle CSI-RS ports of the CSI-RS configuration of the at least one cell adjacent to the first cell is greater than a first predetermined threshold,
- wherein the first predetermined threshold is set based on at least one of an overhead of signaling bits, a data throughput increase to be obtained by using at least the portion of the time-frequency resources corresponding to the one or more idle CSI-RS ports of the CSI-RS configuration of the at least one cell adjacent to the first cell, or an expected maximum increase in the data throughput to be obtained by using at least the portion of the time-frequency resources corresponding to the one or more idle CSI-RS ports of the CSI-RS configuration of the at least one cell adjacent to the first cell.
