Resource determination for sub-band group

A method of wireless sensing performed by a sensing node, comprising:

• receiving:
• a bitmap for determining a frequency domain resource allocation of a sub-band group (SBG), the SBG comprising a plurality of non-contiguous sub-bands (SBs) separated by one or more inter-sub-band frequency apertures (ISFAs);
• and
• one or more granularity parameters for the SBG, indicating a first number of frequency units associated with the plurality of non-contiguous SBs and a second number of frequency units associated with the one or more ISFAs;
• and
• transmitting or receiving one or more sensing signals via one or more frequency resources within the plurality of non-contiguous SBs, wherein the one or more frequency resources are identified based on the bitmap and the one or more granularity parameters.

A sensing node comprising:

• one or more memories;
• one or more transceivers;
• and
• one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
• receive, via the one or more transceivers a message comprising a resource indicator value (RIV) field, wherein:
• based on n_k being less-than-or-equal-to (n_SBG/2)+1, the RIV field indicates n_SBG*(n_k−1)+SB_start,k;
• based on n_k being greater-than (n_SBG/2)+1, the RIV field indicates n_SBG*(n_SBG−n_k+1)+(n_SBG−1−SB_start,k);
• n_SBG multiplied by a granularity parameter is equal to a total bandwidth of a sub-band group (SBG), the SBG comprising a plurality of non-contiguous sub-bands (SBs) separated by one or more inter-sub-band frequency apertures (ISFAs);
• n_k multiplied by the granularity parameter is equal to a bandwidth of a sub-band k of the plurality of non-contiguous SBs;
• and
• SB_start,k is a start frequency of the sub-band k;
• select, based on the RIV field, one or more frequency resources within the plurality of non-contiguous SBs;
• and
• transmit or receive, via the one or more transceivers, a sensing signal via the one or more frequency resources.
