Method for prioritizing operation of relay node in a wireless communication system and apparatus for the same

摘要

Various methods and apparatuses for prioritizing operation of Relay Node are disclosed. A method for prioritizing the transmission and receipt of uplink signals in a relay node of a wireless communication system is presented. The method comprises determining radio resource requirements for receiving one or more access link signals and/or transmitting one or more backhaul link signal, determining the signal type of the one or more access link signals and/or determining the signal type of the one or more backhaul link signals, and selecting one of a transmitting mode operation and a receiving mode operation based on the radio resource requirements for receiving the one or more access link signals and/or transmitting the one or more backhaul link signals, and based on the signal type of the one or more access link signals and/or the signal type of the one or more backhaul link signals.

主权项

1. A method for transmitting a signal from a Relay Node (RN) to an eNodeB (eNB) in a wireless communication system, the method comprising:
receiving, by the RN from the eNB, configuration information about plural subframes for a transmission from the RN to the eNB; determining, by the RN, an uplink subframe for transmitting a Scheduling Request (SR) from the RN to the eNB from among the plural subframes, the plural subframes being different in time from a subframe that is configured by the RN for a reception from a User Equipment (UE) by the RN, the SR being a request to schedule uplink transmissions from the RN to eNB; transmitting, by the RN to the eNB, data in the plural subframes, wherein the SR is simultaneously transmitted with the data by the RN to the eNB only in the determined uplink subframe of the plural subframes.
