US 9,432,136 B2 · Method for supporting a dynamic-time division duplex (D-TDD) downlink-uplink configuration in a wireless communication system, and apparatus therefor

Abstract

Disclosed is a method for supporting a dynamic-time division duplex (D-TDD) downlink-uplink configuration in a wireless communication system and to an apparatus therefor. A method in which a first network node supports a dynamic-time division duplex (D-TDD) downlink-uplink configuration according to one embodiment of the present invention comprises a step of selecting two or more TDD downlink-uplink configurations from among a plurality of predefined TDD downlink-uplink configurations based on a predetermined rule so as to establish a set of TDD downlink-uplink configurations, wherein the predetermined rule may enable the selection of two or more TDD downlink-uplink configurations from a number of downlink subframe durations constituted by subframes other than a downlink subframe, or from a number of uplink subframe durations constituted by subframes other than an uplink subframe.

A method of supporting a dynamic-time division duplex (D-TDD) downlink-uplink configuration by a base station in a wireless communication system, the method comprising:

receiving at least one TDD downlink-uplink configuration set from a network node,
wherein the at least one TDD downlink-uplink configuration set is configured by selecting a plurality of TDD downlink-uplink configurations according to a predetermined rule among a plurality of predefined TDD downlink-uplink configurations,
wherein the at least one TDD downlink-uplink configuration set comprises the plurality of TDD downlink-uplink configurations,
wherein, according to the predetermined rule, the at least one TDD downlink-uplink configuration set including the plurality of TDD downlink-uplink configurations is configured based on a number of subframes having a different subframe type per subframe index between the plurality of the TDD downlink-uplink configurations, and
wherein subframe types of the TDD downlink-uplink configurations comprise a downlink subframe type, an uplink subframe type, and a special subframe type;
and
when a neighbor base station uses the D-TDD downlink-uplink configuration, using one of only the at least one TDD downlink-uplink configuration set of the predefined TDD downlink-uplink configurations.
