1. A method of initiating a sidelink operation between a first wireless electronic device and a second wireless electronic device in an unlicensed spectrum, comprising the steps of:
receiving, at the first wireless device, one or more first configuration parameters of a sidelink bandwidth part (BWP) for the sidelink operation, wherein the one or more first configuration parameters include at least one channel occupancy time (COT) signal for a first COT sharing;
obtaining, after the step of receiving, one or more second configuration parameters for a transmission sidelink resource pool, wherein the one or more second configuration parameters include at least one priority value for the first COT sharing;
determining (i) a first sidelink transmission of the sidelink operation from the one or more first configuration parameters, and (ii) a first priority level of the first sidelink transmission from the one or more second configuration parameters;
decoding a first sidelink control information (SCI) to indicate an offset value and a first COT duration for the first COT sharing; and
transmitting the first sidelink transmission and the first SCI to the second wireless electronic device.

5. A method of sharing a channel occupancy time (COT) between a first wireless electronic device and a second wireless electronic device, comprising the steps of:
receiving, by the first wireless electronic device from the second wireless electronic device at a first time, a first sidelink control information (SCI) including (i) a first COT sharing, and (ii) a first priority value of a channel access;
determining (i) a second priority value of the channel access for a sidelink transmission, and (ii) at least one sidelink resource for a sidelink transmission;
calculating a first channel access type based on the first COT sharing, the first time, the first priority value, and the second priority value;
executing the first channel access type; and
transmitting the sidelink transmission and the first SCI based on a successful execution of the first channel access type.

6. A method of selecting a listen-before-talk (LBT) category for a wireless electronic device, comprising the steps of:
receiving, by the wireless electronic device, (i) a first sidelink control information (SCI) indicating a sharing of channel occupancy time (COT) having a first time domain resource, and (ii) a second SCI indicating a sidelink feedback mode and a destination identity;
determining, from the second SCI (i) a receiving sidelink shared channel scheduled by the second SCI, and (ii) a sidelink feedback scheduling based on the sidelink feedback mode;
selecting at least one of a first LBT type and a second LBT type based on (i) the sidelink feedback scheduling, (ii) the sharing of the COT, (iii) a second time domain resource overlapping with the first time domain resource of the COT, and (iv) a feedback resource for a sidelink feedback of the sidelink feedback mode; and
transmitting the sidelink feedback based on the selected LBT type.

11. A method of configuring, by a wireless electronic device, one or more subchannels of a communication channel for interlacing, comprising the steps of:
receiving, by the wireless electronic device, configuration parameters of a sidelink operation in an unlicensed spectrum, the configuration parameters including (i) a starting frequency point of a common resource block (RB) determined to have a lowest index among one or more RBs of a first subchannel of the one or more subchannels, (ii) an enabling interlaced transmission parameter configured to enable determination of a resource for a sidelink transmission based on one or more interlace RBs, (iii) a starting RB index of the first subchannel determined to have a lowest RB index within a resource pool, (iv) a size of the first subchannel within the resource pool, and (v) a number of subchannels within the resource pool;
determining a first set of RBs for the first subchannel based on (i) the enabling interlaced transmission parameter, (ii) the starting frequency point, and (iii) the size of the first subchannel; and
transmitting a sidelink transmission using resources based on the determined first set of RBs for the first subchannel, wherein the sidelink transmission includes a sidelink control information (SCI) indicating the first subchannel.
