TIMING ALIGNMENT FOR INTER-UE CROSS-LINK INTERFERENCE MITIGATION IN SUB-BAND FULL-DUPLEX CELLULAR SYSTEMS

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a UE. In certain configurations, the UE receives, from a base station, a configuration instruction for enabling a subband full duplex (SBFD) timing alignment (TA) mechanism and a constant c. The UE enables the SBFD TA mechanism according to the configuration instruction. The UE receives, from the base station, a timing adjustment command, which includes a propagation delay δi for the UE. The UE determines whether an uplink (UL) transmission is to be performed in a SBFD slot. In response to determining the UL transmission to be performed in the SBFD slot, the UE applies a timing alignment delay to the UL transmission with respect to the SBFD slot start boundary. The timing alignment delay is determined by both the constant c and the propagation delay δi.
