Method and device for transmitting response information, and resource allocation for response information transmission according to transmission conditions in a wireless communication system

摘要

A method for allocating a resource for response information transmission and transmitting according to transmission conditions in a wireless communication system according to the present invention comprises the steps of: setting a specific field value of a control channel depending on the allocation method by determining a transmission method or transmission quantity of data to be transmitted to a user's terminal from a data channel, a method of generating response information of the data according to the transmission quantity or transmission method, and an allocation method for indicating the response information resource; transmitting the data channel including the transmitting data and the control channel to the user's terminal; confirming the response information, which is transmitted from a resource allocated by the allocation method, for the data transmitted from the user's terminal; and determining whether the transmitted data area retransmitted according to the confirmed response information.

1. A method of allocating a resource for response information transmission based on a transmission environment in a wireless communication system, the method comprising:
determining a transmission scheme or an amount of data to be transmitted from a data channel to a user equipment, determining, based on the transmission scheme or the amount of data to be transmitted, a scheme of generating response information with respect to the data and an allocation scheme indicating a response information resource, and setting a value of a predetermined field of a control channel based on the allocation scheme; transmitting, to the user equipment, the control channel and the data channel including the data to be transmitted; determining response information transmitted from the user equipment with respect to the transmitted data in the resource allocated based on the allocation scheme; and determining whether to retransmit the transmitted data based on the determined response information, wherein the allocation scheme corresponds to one of an implicit allocation scheme that implicitly performs calculation in a first field of the control channel and an explicit allocation scheme that explicitly performs calculation in a second field of the control channel.
