Flexible sidelink control information periodicity for sidelink semi-persistent scheduling

A transmitter user equipment (UE) comprising at least one processor and a memory configured to:

• establish a sidelink communication with a receiver UE;
• schedule with at least one semi-persistent scheduling (SPS) process at a first time interval;
• transmit one or more sidelink control information (SCI) messages to the receiver UE at a second time interval greater than the first time interval;
• and
• sense whether a resource is available for transmissions to the receiver UE based on decoding the one or more SCI messages.

A transmitter user equipment (UE) for wireless communications, comprising:

• means for establishing a sidelink communication with a receiver UE;
• means for scheduling with at least one semi-persistent scheduling (SPS) process at a first time interval;
• means for transmitting one or more sidelink control information (SCI) messages to the receiver UE at a second time interval greater than the first time interval;
• and
• means for sensing whether a resource is available for transmissions to the receiver UE based on decoding the one or more SCI messages.

A non-transitory computer readable medium storing instructions that when executed by a transmitter user equipment (UE) cause the transmitter UE to:

• establish a sidelink communication with a receiver UE;
• schedule with at least one semi-persistent scheduling (SPS) process at a first time interval;
• transmit one or more sidelink control information (SCI) messages to the receiver UE at a second time interval greater than the first time interval;
• and
• sense whether a resource is available for transmissions to the receiver UE based on decoding the one or more SCI messages.
