Patent ID: 8917652

Claim:
A method for processing backhaul Uplink Control Information (UCI), comprising: a Relay Node (RN) determining Q′ which is the number of coded modulation symbols of the backhaul UCI according to the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols occupied by a Guard Period (GP), wherein the GP comprises a RN state switch time ΔT and/or a time interval Δt which is reserved for avoiding the interference caused by RN uplink transmission, and the ΔT is the switch time that the RN requires 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 coding the backhaul UCI into a Q=Q′×Q m bits sequence, wherein Q m is the number of bits comprised in each coded modulation symbol in a modulation order of a backhaul uplink subframe.
