Abstract:
1. A method for base station (eNB) to relay node (RN) (eNB-RN) transmissions in accordance with an orthogonal frequency division multiple access (OFDMA) technique, the method comprising: configuring sub-frames in accordance with an uplink-downlink configuration and a subframe configuration for an eNB to RN transmission, each sub-frame comprising slots for transmitting signals within resource blocks, wherein a cyclic prefix (CP) having a predetermined length is appended to each symbol of the sub-frames; transmitting symbols of the sub-frames that are pre-designated for downlink transmission based on the uplink-downlink configuration and the subframe configuration; and configuring the subframes in accordance with a slot configuration, the slot configuration to restrict transmissions to a subset of symbols in a slot, wherein the slot configuration indicates a start symbol index and an end symbol index for at least one of a first slot and a second slot of a resource block, and wherein the uplink-downlink configuration and the subframe configuration define a frame structure that indicates which sub-frames of a frame are downlink subframes pre-designated for eNB-RN transmissions and which subframes are uplink subframes pre-designated for RN-eNB transmissions.
