Method, system, and device for confirming uplink-downlink configuration

摘要

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.

1. A method of determining an uplink-downlink configuration, comprising:
determining, by a network-side apparatus, 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 first RSRP value is measured and reported by a NodeB serving the first cell to the network-side apparatus; and comparing, by the network-side apparatus, the first RSRP value with a power threshold corresponding to the first cell, and determining from the comparison result whether or not the first cell autonomously selects uplink-downlink configuration, the uplink-downlink configuration being allocation of subframes in each radio frame for uplink transmission and for downlink transmission, wherein the determining, by the network-side apparatus, whether or not the first cell autonomously selects the uplink-downlink configuration comprises:
comparing, by the network-side apparatus, the first RSRP value with the power threshold corresponding to the first cell and determining whether the first RSRP value is below the power threshold, and if so, then determining that the first cell selects the uplink-downlink configuration autonomously; otherwise, determining that the first cell does not select the uplink-downlink configuration autonomously.
