1. A computer readable storage medium comprising a set of instructions, wherein the set of instructions when executed by a processor of a user equipment (UE) causes the processor to perform operations, comprising:
receiving a signal broadcast by a cell of a network over a channel in the unlicensed spectrum, wherein the signal includes a set of channel state information reference signals (CSI-RS) each corresponding to a set of synchronization signal blocks (SSB) and is transmitted during a discovery reference signal (DRS) window;
determining a location of the set of CSI-RS within the DRS window;
performing an operation based on the set of CSI-RS;
determining that a first CSI-RS is quasi co-located (QCLed) with one or more further CSI-RS; and
determining that the one or more CSI-RS are not transmitted by the cell based on determining that the presence of the first CSI-RS that is QCLed with the one or more further CSI-RS in the DRS window, wherein the first CSI-RS transmissions is assumed to be QCLed based on NCSI-RS mod NCSI-RSQCL, wherein NCSI-RS(0≤NCSI-RS<M) represents a CSI-RS index within the DRS window and NCSI-RSQCL represents a number of non-QCLed NCSI-RS and is provided by the network in a system information block 1 (SIB1) or a physical broadcast channel (PBCH), wherein M represents a predetermined number of CSI-RS.
