METHOD AND APPARATUS FOR TRANSMITTING SIGNAL VIA RELAY BACKHAUL LINK |
| 摘要 |
A method and a base station (BS) for transmitting a signal, and method and a relay for receiving a signal in a wireless communication system are discussed. The method for transmitting a signal according to an embodiment includes mapping a reference signal to a subframe comprising a first slot and a second slot. Each of the first and second slots includes a plurality of resource elements over which the reference signal is allowed to be mapped. When a last orthogonal frequency division multiplexing (OFDM) symbol of the subframe is not available for a BS-to-relay transmission, the reference signal is not mapped to the second slot and a data signal is mapped to the resource elements of a penultimate OFDM symbol of the second slot. The method further includes transmitting the reference signal to a relay. |

1. A method for transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:
mapping, by the BS, a reference signal to a subframe comprising a first slot and a second slot, wherein each of the first and second slots includes a plurality of resource elements over which the reference signal is allowed to be mapped, and wherein, when a last orthogonal frequency division multiplexing (OFDM) symbol of the subframe is not available for a BS-to-relay transmission, the reference signal is not mapped to the second slot and a data signal is mapped to the resource elements of a penultimate OFDM symbol of the second slot; and transmitting, by the BS, the reference signal to a relay. |
