CELLULAR FEEDBACK TRANSMISSION FOR USER EQUIPMENTS ENABLING DEVICE-TO-DEVICE COMMUNICATIONS

摘要

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.

主权项

1. A method implemented at least in part by user equipment comprising:
responsive to receiving information from a base station in a cellular system, generating feedback associated with the received information; and multiplexing the feedback with a device-to-device (D2D) signal in a subframe for transmission.
