Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a first message from a first wireless communication device and a second message from a second wireless communication device, obtains information associated with a first processing delay with respect to the first message and a second processing delay with respect to the second message, and transmits a third message comprising an indication of the information associated with the first and second processing delays.
Claims54
A method of wireless communication comprising:
- receiving a first message from a first wireless communication device and a second message from a second wireless communication device;
- obtaining information associated with a first processing delay with respect to the first message and a second processing delay with respect to the second message;
- and
- transmitting a third message comprising:
- an indication of the information associated with the first and second processing delays, and
- an accuracy associated with the first and second processing delays.
