Abstract: Method and apparatus for processing hybrid automatic repeat request process in communication system are disclosed. An operation method of a communication node comprises configuring one or more hybrid automatic repeat request (HARQ) groups; and deploying at least one HARQ process identifier (ID) in each of the one or more HARQ groups, wherein each of the one or more HARQ groups includes a HARQ memory group, a memory controller group controlling the HARQ memory group, and a decoder group performing a decoding based on data stored in the HARQ memory group by accessing the HARQ memory group through the memory controller group. Therefore, performance of the communication system may be enhanced.

Abstract: An operation method of a relay base station in a communication network including a central base station, the relay base station, and a terminal may comprise receiving a request message for requesting a low latency service from the terminal; in response to the request message, measuring a signal quality of a radio link between the central base station and the relay station and a signal quality of a radio link between the relay base station and the terminal; determining whether to support the low latency service based on the signal qualities; and when the low latency service is determined to be supported, transmitting downlink data received from the central base station to the terminal without performing modulation and demodulation operations, or transmitting uplink data received from the terminal to the central base station without performing modulation and demodulation operations.

Abstract: Provided are an uplink frequency control method and a terminal apparatus using the same. The uplink frequency control method includes measuring a frequency offset with respect to a downlink, deriving a frequency offset component with respect to an uplink through the measured frequency offset, and correcting an uplink frequency offset using the derived frequency offset component. Therefore, by controlling an uplink frequency through a simple operation in a terminal, baseband design of a base station can be simplified, and uplink SNR performance can be improved.
