8 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the DL reception through the first resource without performing the UL transmission through the second resource if the first indication is a dynamic scheduled DCI and the second indication is a higher layer configuration.
9 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the DL reception through the first resource without performing the UL transmission through the second resource if a first priority indicated by the first indication is higher than a second priority indicated by the second indication, the first indication is a dynamic scheduled DCI and the second indication is another dynamic scheduled DCI.
10 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the DL reception through the first resource without performing the UL transmission through the second resource if a receiving time of the first indication is later than a receiving time of the second indication, the first indication is a dynamic scheduled DCI, the second indication is another dynamic scheduled DCI, and a first priority indicated by the first indication is identical with a second priority indicated by the second indication.
11 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the UL transmission through the second resource without performing the DL reception through the first resource if the UL transmission is a Message 1 (Msg 1 ) or a Message 3 (Msg 3 ) of random access (RA) procedure.
12 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the UL transmission through the second resource without performing the DL reception through the first resource if a second priority indicated by the second indication is higher than a first priority indicated by the first indication, the first indication is a dynamic scheduled DCI and the second indication is another dynamic scheduled DCI.
13 . The method according to claim 1 , wherein the step of performing the DL reception through the first resource or the UL transmission through the second resource according to the rule comprises:
performing the UL transmission through the second resource without performing the DL reception through the first resource if a receiving time of the second indication is later than a receiving time of the first indication, the first indication is a dynamic scheduled DCI, the second indication is another dynamic scheduled DCI, and a first priority indicated by the first indication is identical with a second priority indicated by the second indication.
14 . He method according to claim 1 , wherein the first indication is a higher layer configuration or a dynamic scheduled DCI.
15 . The method according to claim 1 , wherein the second indication is a higher layer configuration or a dynamic scheduled DCI.
16 . He method according to claim 1 , wherein the first resource is a DL resource and the second resource is a flexible resource.
17 . He method according to claim 1 , wherein the first resource is a flexible resource and the second resource is a UL resource.
18 . He method according to claim 1 , wherein the first resource is a flexible resource and the second resource is another flexible resource.
19 . The method according to claim 1 , wherein the first resource is a DL resource and the second resource is a UL resource.
20 . A method for duplex operation used by a user equipment (UE), the method comprising:
