Method for processing degradation of radio link quality in a wireless communication system supporting relays

摘要

A method and apparatus for processing degradation of radio link quality in a wireless communication system supporting relays are disclosed. The method includes determining quality of a radio link between the first node and the communication apparatus, recovering the radio link between the first node and the communication apparatus, when the quality of the radio link between the first node and the communication apparatus is decreased to or below a predetermined threshold, and transmitting to the second node a signaling to control communication on a radio link between the second node and the communication apparatus, when the quality of the radio link between the first node and the communication apparatus is decreased to or below the predetermined threshold.

1. A method for processing degradation of radio link quality in a Relay Node (RN) connected wirelessly to a Base Station (BS) and a User Equipment (UE), the method comprising:
determining, at the RN, quality of a radio link between the BS and the RN; recovering, at the RN, the radio link between the BS and the RN, when the quality of the radio link between the BS and the RN is decreased to or below a predetermined threshold; and transmitting, at the RN, to the UE a signaling to control communication on a radio link between the UE and the RN, when the quality of the radio link between the BS and the RN is decreased to or below the predetermined threshold.
