Determining a reference timing for a discovery procedure

A method of wireless communication performed by a host device, comprising:

• determining, based at least in part on a worst case difference between internal timings of the host device and a client device that receives a discovery signal from the host device, whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing as a reference timing to be used to monitor for a response to the discovery signal;
• determining the reference timing to be used to monitor for the response to the discovery signal based at least in part on the determination of whether to use the receive timing, the internal timing of the client device that receives the discovery signal, or the combination of the receive timing and the internal timing;
• transmitting the discovery signal;
• and
• monitoring a set of resources for the response based at least in part on the reference timing.

A client device for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• receive, from a host device, a discovery signal;
• determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing based at least in part on a worst case difference between internal timings of the client device and the host device;
• configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing;
• and
• transmit the response to the host device using the configured reference timing.
