This disclosure generally relates to cellular feedback transmission for the user equipments enabling D2D communications. In one embodiment, the cellular uplink feedback and the D2D signals may be multiplexed in the same D2D subframe. For example, the feedback may be transmitted using a symbol that is not used to carry the D2D signal. In one embodiment, the feedback may be transmitted in the symbol that is kept as gap in the D2D subframe. By multiplexing the cellular feedback with the D2D signals, the cellular feedback can be transmitted to the BS without breaking off the D2D transmission. |
