a first transmitter configured to transmit a first signal to the first network node;
wherein the first signaling is used to indicate a first time window associated with a data radio bearer (DRB), and based on a radio resource control (RRC) state of the UE, used to determine a second time window in which time-frequency resources are allocated for communications associated with the DRB with a non-terrestrial network (NTN) node different than the first network node, wherein the first signal requests scheduling for the data radio bearer outside the first time window for communications associated with the DRB via the NTN node during the second time window.
2 . The UE according to claim 1 , wherein the first time window and the second time window are associated with a Protocol Data Unit (PDU) session.
3 . The UE according to claim 2 , wherein the UE automatically enters into a state other than a PDU session active state after the first and the second time windows.
4 . The UE according to claim 1 ,
wherein the first receiver is further configured to receive a second signaling;
indicating processing required by the UE after the first and the second time windows.
5 . The UE according to claim 1 , wherein the UE automatically enters into a state other than an RRC connected state after the first and the second time windows.
6 . The UE according to claim 1 , wherein resources employed by the UE are released by a serving cell of the UE after the first time window.
7 . The UE according to claim 1 , wherein the first signal is used for random access with the NTN node, the first signal comprises second information for indicating a cause of the random access for allocation of the time-frequency resources in the second time window.
8 . The UE according to claim 1 , wherein the second time window is related to a geographic position of the UE.
9 . The UE according to claim 1 , wherein the UE is prohibited to transmit scheduling request information in the first time window, and a Scheduling Request count of the UE is not increased in the first time window.
10 . The UE according to claim 1 ,
wherein the first receiver is further configured to receive, a third signaling; and
the first transmitter is configured to transmit, a third signal;
wherein the third signaling comprises a first time window set for determining whether the third signal is used for determining a second time window set, the first time window set and the second time window set comprise K1 time window(s), the K1 time window(s) is (are) associated with K1 time-frequency resource set(s), K1 being a positive integer.
11 . A base station for wireless communications, comprising:
a transmitter configured to transmit a first signaling to a user equipment (UE); and
a receiver configured to receive a first signal from the UE;
wherein whether the first signaling is used to indicate a first time window associated with a data radio bearer (DRB), and based on a radio resource control state of the UE, and used for determining a second time window in which time-frequency resources are allocated for communications associated with the DRB with a non-terrestrial (NTN) node different than the base station wherein the first signal requests scheduling for the data radio bearer outside the first time window for communications associated with the DRB via the NTN node during the second time window.
12 . A method for a user equipment (UE) for wireless communications, the method comprising:
receiving a first signaling from a first network node; and
transmitting a first signal to the network node responsive to the first signaling;
wherein the first signaling is used to indicate a first time window associated with a data radio bearer (DRB), and based on a radio resource control (RRC) state of the UE, for determining a second time window in which time-frequency resources are allocated for communications associated with the DRB with a non-terrestrial network (NTN) node different than the first network node, wherein the first signal requests scheduling for the data radio bearer outside the first time window for communications associated with the DRB via the NTN node during the second time window.
13 . The method according to claim 12 , wherein the first time window and the second time window are associated with a Protocol Data Unit (PDU) session.
14 . The method according to claim 13 , wherein the UE automatically enters into a state other than a PDU session active state after the first and the second time windows.
15 . The method according to claim 12 , comprising:
receiving a second signaling for indicating processing required by the UE after the first and the second time windows.
16 . The method according to claim 12 , wherein the UE automatically enters into a state other than an RRC connected state after the first and the second time windows.
17 . The method according to claim 12 , wherein resources employed by the UE are released by a serving cell of the UE after the first and the second time windows.
18 . The method according to claim 12 , wherein the first signal is used for random access with the NTN node, the first signal comprises second information for indicating a cause of the random access, and the second information is related to the second time window.
19 . The method according to claim 12 , wherein the second time window is related to a geographic position of the UE.
20 . The method according to claim 12 , wherein the UE is prohibited to transmit scheduling request information in the first time window, and a Scheduling Request count of the UE is not increased in the first time window.
