US 2017/0257185 A1 · APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM SUPPORTING HYBRID AUTOMATIC REPEAT REQUEST SCHEME

Abstract

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting a signal in transmitting apparatus in a wireless communication system supporting a hybrid automatic repeat request (HARQ) scheme is provided. The method includes transmitting a signal to a receiving apparatus; detecting there is a need for a retransmission operation for the signal; and performing the retransmission operation for the signal based on at least one of a reception scheme used in the receiving apparatus or an interference characteristic of an interference signal.

Dependent claims

A transmitting apparatus in a wireless communication system supporting a hybrid automatic repeat request (HARQ) scheme, the transmitting apparatus comprising:

a processor configured to:
transmit a signal to a receiving apparatus,
detect whether to perform a retransmission operation for the signal, and
perform the retransmission operation for the signal based on at least one of a reception scheme used in the receiving apparatus or an interference characteristic of an interference signal.

1 more element

A receiving apparatus in a wireless communication system supporting a hybrid automatic repeat request (HARQ) scheme, the receiving apparatus comprising:

a processor configured to:
receive a signal from a transmitting apparatus,
generate feedback information for the signal based on at least one of a reception scheme used in the receiving apparatus or an interference characteristic of an interference signal, and transmit the feedback information to the transmitting apparatus.

Dependencies are inferred from the claim text.
