METHOD, SYSTEM, AND DEVICE FOR CONFIRMING UPLINK-DOWNLINK CONFIGURATION
First Claim
1. A method of determining an uplink and downlink configuration, comprising:
- a network-side apparatus determining a first Reference Signal Received Power, RSRP, value of a reference signal of a second cell received by a first cell, wherein the second cell is an adjacent cell to the first cell; and
the network-side apparatus determining from the first RSRP value whether the first cell can select an uplink and downlink configuration autonomously.

Abstract
Embodiments of the present invention relate to the technical field of wireless communication, and relate particularly to a method, a system, and a device for confirming an uplink-downlink configuration, for use in confirming via interference detection whether or not a cell is capable of conducting independently the uplink-downlink configuration. The method of the embodiments of the present invention comprises: a network side device confirming the receipt of a first RSRP value of a reference signal from a second cell by a first cell, the second cell being an adjacent cell of the first cell (201); on the basis of the first RSRP value, the network side device confirming whether or not the first cell is capable of conducting autonomously the uplink-downlink configuration (202). Measuring the RSRP value to determine whether or not the cell is capable of conducting independently the uplink-downlink configuration allows for the normal operation of a dynamic uplink-downlink configuration, reduced interference between adjacent cells in a dynamic uplink-downlink configuration environment, and improved system efficiency.
