METHOD, SYSTEM AND RELAY NODE FOR PROCESSING UPLINK CONTROL INFORMATION ON BACKHAUL LINK

摘要

The disclosure discloses a method, system and RN for processing UCI on a backhaul link. The method comprises that: the RN determines Q′ which is the number of the coded modulation symbols of the backhaul UCI according to the number of SC-FDMA symbols occupied by a GP, wherein the GP comprises RN state switch time deltaT and/or the time interval deltat which is reserved for avoiding the interference caused by RN uplink transmission, and deltaT is the switch time required by the RN to switch from an uplink reception state to an uplink transmission state and/or from the uplink transmission state to the uplink reception state; and the RN codes the backhaul UCI into a Q=Q′×Qm bits sequence, wherein Qm is the number of bits comprised in each coded modulation symbol in the modulation order of the backhaul uplink subframe. The disclosure improves the performance of the system.
