Measurement signals for sensing

A method of a receiver configured to operate as a sensing device, the method comprising:

• transmitting a precoding setting request for a plurality of measurement signals for channel estimation, the precoding setting request being indicative of one or more precoding settings prioritized for sensing by indicating one or more spatial directions associated with emission caused by the one or more precoding settings prioritized for sensing;
• receiving one or more physical layer packet comprising the plurality of measurement signals for channel estimation, precoding settings being used based on the precoding setting request;
• receiving a precoding setting announcement indicative of configured precoding settings of the one or more precoding settings;
• and
• performing channel estimation based on the plurality of measurement signals for channel estimation.

A non-transitory computer storage medium, having thereon a computer program comprising program instructions, the computer program being loadable into a data processing unit and configured to cause execution of a method when the computer program is run by the data processing unit, the method comprising:

• receiving, from a sensing device, a precoding setting request for measurement signals for channel estimation, the precoding setting request being indicative of one or more precoding settings prioritized for sensing by indicating one or more spatial directions associated with emission caused by the one or more precoding settings prioritized for sensing;
• configuring a transmitter to use precoding settings for the plurality of measurement signals for channel estimation based on the precoding setting request;
• and
• transmitting the one or more physical layer packets and a precoding setting announcement indicative of configured precoding settings of the one or more precoding settings.

An apparatus for a transmitter configured to transmit one or more physical layer packets, which together comprise a plurality of measurement signals for channel estimation, the apparatus comprising controlling circuitry configured to cause:

• reception, from a sensing device, of a precoding setting request for the measurement signals for channel estimation, the precoding setting request being indicative of one or more precoding settings prioritized for sensing by indicating one or more spatial directions associated with emission caused by the one or more precoding settings prioritized for sensing;
• configuration of the transmitter to use precoding settings for the plurality of measurement signals for channel estimation based on the precoding setting request;
• and
• transmission of the one or more physical layer packets and a precoding setting announcement indicative of configured precoding settings of the one or more precoding settings.
