Bidirectional sidelink communications enhancement

A method for sidelink wireless communications comprising:

• receiving, by a first user equipment (UE), configuration parameters, of a cell for sidelink communications with a second UE, the configuration parameters comprising:
• first configuration parameters of a first bandwidth part (BWP) of the cell for transmission of one or more first sidelink signals and channels by the first UE to the second UE;
• and
• second configuration parameters of a second BWP of the cell for reception of one or more second sidelink signals and channels by the first UE from the second UE,
• wherein:
• the first configuration parameters indicate first radio resources of the cell and a first numerology for the first BWP of the cell for the transmission of the one or more first sidelink signals;
• and
• the second configuration parameters indicate second radio resources of the cell and a second numerology for the second BWP of the cell for the transmission of the one or more second sidelink signals;
• transmitting, by the first UE, the one or more first sidelink signals and channels via the first BWP and based on the first configuration parameters;
• and
• receiving, by the first UE, the one or more second sidelink signals and channels via the second BWP and based on the second configuration parameters.
