Method and apparatus for allocating channels related to uplink bundling

摘要

A new PHICH channel and a new PDCCH channel are allocated when the location of a subframe to be used in transmission changes by the change in the configuration of the subframe caused by a dynamic uplink/downlink configuration in a subframe bundling transmission mode. In the event that a subframe is successfully transmitted in a subframe bundling mode, the location of the subframe that has been successfully transmitted is determined as a reference in determining the point of time of the response to the bundling transmission. In addition, the bundling transmission following the subframe that has been successfully transmitted can be omitted.

1. A method for transmitting uplink data using subframe bundling of transmitting an uplink signal in a predetermined number of subframes by a user equipment in a wireless communication system, the method comprising:
determining a first reception timing point of an uplink grant for the uplink data based on a subframe (hereinafter, a first subframe) for application of the subframe bundling according to an uplink-downlink configuration; changing the subframe for application of the subframe bundling according to an uplink-downlink reconfiguration; determining a second reception timing point of the uplink grant for the uplink data based on the changed subframe (hereinafter, a second subframe); and attempting to decode the uplink grant for the subframes at the first reception timing point and the second reception timing point, when the subframe for application of the subframe bundling is changed from the first subframe to the second subframe due to the uplink-downlink reconfiguration, when decoding of the uplink grant is successful at both the first reception timing point and the second reception timing point, the uplink data is transmitted based on the uplink grant of earlier one of the first reception timing point and the second reception timing point, using the subframe bundling.
