    摘要: A method, apparatus and system for downlink pilot transmission solve the problem of power differences among OFDM symbols caused by Walsh Codes. The transmission method is that dedicated pilots are transmitted in the manner of code division multiplexing (CDM) or hybrid of CDM and frequency division multiplexing (FDM), wherein the dedicated pilots are configured with orthogonal sequence sets according to a preset frequency-domain granularity and rules on the resources for transmitting the dedicated pilots, and the same orthogonal sequence set is employed for the dedicated pilots in each frequency-domain granularity.

    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.
