Segmented transmission in NTN IoT
Methods and apparatuses for segmented transmission in NTN IoT are disclosed. A method comprises transmitting uplink data on a physical resource, wherein, at least a gap with a first length duration is inserted in the physical resource so that the uplink data is postponed to be transmitted after the gap, or at least a data segment of the uplink data with a second length duration is punctured.
1 . A method performed by a user equipment (UE), the method comprising:
transmitting uplink data on a physical resource, wherein after a first length duration of continuous uplink data transmission, a data segment of the uplink data with a second length duration is punctured or not transmitted in the physical resource, and wherein the first length duration is configured by a higher layer with a time slot unit or a physical resource unit, and wherein the second length duration is configured as a unit of a symbol, a time slot, or a mini-second.
2 . The method of claim 1 , further comprising:
inserting a gap with a third length duration in the physical resource so that the uplink data is postponed for transmission after the gap, wherein the gap is inserted after a length duration determined by a slot unit duration and a fourth length duration.
3 . The method of claim 2 , wherein the length duration determined by the slot unit duration and the fourth length duration is minimum integer times of the slot unit duration no smaller than the fourth length duration.
4 . The method of claim 2 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on the whole slot unit of the uplink data would be segmented by the gap.
5 . The method of claim 2 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on starting transmission of the whole slot unit of the uplink data is in a last uplink subframe before the gap.
6 . The method of claim 2 , wherein a gap timer is associated with the third length duration, the gap timer restarts when the uplink data restarts after any uplink data transmission suspending or after the gap.
7 . The method of claim 2 , wherein at least one of the third length duration, or the second length duration is determined by at least one of:
a time offset drift rate;
an identical repetition number of the uplink data;
a non-terrestrial network (NTN) deployment scenario; or
at least one of a frequency hopping interval or a scaling factor.
8 . The method of claim 2 , wherein both time adjustment and frequency adjustment are performed in the gap.
9 . The method of claim 1 , wherein time adjustment is performed in the data segment of the uplink data with the second length duration being punctured.
10 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
transmit uplink data on a physical resource, wherein, after a first length duration of continuous uplink data transmission, a data segment of the uplink data with a second length duration is punctured or not transmitted in the physical resource, and wherein the first length duration is configured by a higher layer with a time slot unit or a physical resource unit, and wherein the second length duration is configured as a unit of a symbol, a time slot, or a mini-second.
11 . The UE of claim 10 , wherein the at least one processor is configured to cause the UE to insert a gap with a third length duration in the physical resource, and postpone transmission of the uplink data after the gap.
12 . The UE of claim 11 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on the whole slot unit of the uplink data would be segmented by the gap.
13 . The UE of claim 11 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on starting transmission of the whole slot unit of the uplink data is in a last uplink subframe before the gap.
14 . The UE of claim 11 , wherein a gap timer is associated with the third length duration, the gap timer restarts when the uplink data restarts after any uplink data transmission suspending or after the gap.
15 . The UE of claim 11 , wherein time adjustment and frequency adjustment are performed in the gap.
16 . A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
transmit uplink data on a physical resource, wherein, after a first length duration of continuous uplink data transmission, a data segment of the uplink data with a second length duration is punctured or not transmitted in the physical resource, and wherein the first length duration is configured by a higher layer with a time slot unit or a physical resource unit, and wherein the second length duration is configured as a unit of a symbol, a time slot, or a mini-second.
17 . The processor of claim 16 , wherein the at least one controller is configured to cause the processor to insert a gap with a third length duration in the physical resource, and postpone transmission of the uplink data after the gap.
18 . The processor of claim 17 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on the whole slot unit of the uplink data would be segmented by the gap.
19 . The processor of claim 17 , wherein a whole slot unit of the uplink data is postponed for transmission after the gap based on starting transmission of the whole slot unit of the uplink data is in a last uplink subframe before the gap.
20 . The processor of claim 17 , wherein a gap timer is associated with the third length duration, the gap timer restarts when the uplink data restarts after any uplink data transmission suspending or after the gap.
