1. A method for wireless communications at a network device, the method comprising:
receiving a signal comprising a slot including at least one shared signal resource;
determining the slot is allocated for sensing and communications;
determining to demodulate the at least one shared signal resource using at least one sensing reference signal (RS) resource based on determining the slot is allocated for sensing and communications;
receiving at least one indication signal indicating a subset of ports of a number of sensing RS ports associated with the at least one sensing RS resource for demodulation of the at least one shared signal resource, wherein the number of sensing RS ports is larger than a rank of the at least one shared signal resource; and
demodulating the at least one shared signal resource using the at least one sensing RS resource and the subset of ports.
