wherein the second DCI includes indicator on activation or release SPS for the LTE sidelink.
6. The method of claim 1 , wherein the first sidelink signal comprising a sidelink control information or data corresponding the sidelink control information.
7. A method performed by a base station (BS) for sidelink communication, the method comprising:
transmitting, to a user equipment (UE), system information on a plurality of sidelink resource pools,
wherein, in case that the UE transmits a first sidelink signal, the first sidelink signal is, by the UE, transmitted using one sidelink resource pool among the plurality of the sidelink resource pools,
wherein, in case that the UE receives a second sidelink signal, the second sidelink signal is, by the UE, received using the plurality of the sidelink resource pools, and
wherein the plurality of the sidelink resource pools includes a first resource pool including a feedback channel and a second resource pool which does not include the feedback channel.
8. The method of claim 7 , wherein the plurality of the sidelink resource pools are configured within equal bandwidth parts (BWPs).
9. The method of claim 7 , further comprising:
transmitting, to the UE, a downlink control information (DCI),
wherein the DCI is identified as a first DCI or a second DCI based on a radio network temporary identifier (RNTI),
wherein the DCI is one of:
the first DCI used for a new radio (NR) sidelink, and
the second DCI used for a long term evaluation (LTE) sidelink, and wherein the RNTI is one of:
a first RNTI for the NR sidelink, and
a second RNTI for the LTE sidelink.
10. The method of claim 9 , further comprising:
if the DCI is the second DCI, obtaining timing offset information from the DCI,
wherein the timing offset information comprises information between a NR slot receiving the DCI and an LTE subframe to be applying the DCI.
11. The method of claim 9 ,
wherein the first DCI includes indicator on activation or release semi-persistent scheduling (SPS) for the NR sidelink, and
wherein the second DCI includes indicator on activation or release semi-persistent scheduling (SPS) for the LTE sidelink.
12. The method of claim 7 , wherein the first sidelink signal comprising a sidelink control information or data corresponding the sidelink control information.
13. A user equipment (UE) for sidelink communication, the UE comprising:
at least one transceiver; and
at least one processor, operably connected to the at least one transceiver, and configured to:
receive, from a base station (BS), system information on a plurality of sidelink resource pools, and
identify the plurality of the sidelink resource pools based on the system information,
