Existence of periodic/semi-static signals and channels outside of channel occupancy time (COT)
View Patent ↗A method of a user equipment (UE) in a wireless communication network and a UE are provided. The method includes receiving, from the network, a downlink (DL) transmission, determining, by the UE, whether to cancel at least a portion of the DL transmission, and cancelling, by the UE, at least the portion of the DL transmission when the UE determines that the portion of the DL transmission is to be cancelled.
1. A method of a user equipment (UE) in a wireless communication network, the method comprising:
receiving, from the network, a downlink (DL) transmission, a first portion of the DL transmission overlapping at least a portion of a channel status information (CSI)-reference signal (RS);
determining, by the UE, that a second portion of the DL transmission does not overlap with the CSI-RS; and
allowing, by the UE, the first and second portions of the DL transmission in response to the determination that the second portion of the DL transmission does not overlap with the CSI-RS.
2. The method of claim 1 , wherein the first and second portions of the DL transmission are cancelled when a part of the DL transmission is not within a channel occupancy time (COT).
3. The method of claim 2 , further comprising monitoring, by the UE, downlink control information (DCI),
wherein the COT is indicated in the DCI.
4. The method of claim 1 , further comprising configuring a timer for a predetermined duration,
wherein the first and second portions of the DL transmission are cancelled when a part of the DL transmission occasion is not within the predetermined duration.
5. The method of claim 4 , wherein the timer comprises a timer introduced for switching groups of search space sets.
6. The method of claim 1 , wherein the first and second portions of the DL transmission are cancelled when the DL transmission does not overlap with a set of DL transmissions with a gap.
7. The method of claim 1 , wherein the first and second portions of the DL transmission is determined to be cancelled when the DL transmission is not between a detected downlink control information (DCI) and a scheduled physical downlink shared channel (PDSCH).
8. The method of claim 1 , wherein the first and second portions of the DL transmission are cancelled when any part of the DL transmission is not within a transmission duration.
9. The method of claim 8 , wherein the UE comprises a frame based equipment (FBE).
10. The method of claim 1 , further comprising monitoring, by the UE, for a slot format indicator (SFI),
wherein the first and second portions of the DL transmission are cancelled when no SFI is detected.
11. A user equipment (UE), comprising:
a transceiver;
a memory; and
a processor configured to:
receive, from a network, a downlink (DL) transmission, a first portion of the DL transmission overlapping at least a portion of a channel status information (CSI)-reference signal (RS);
determine that a second portion of the DL transmission does not overlap with the CSI-RS; and
allowing the first and second portion of the DL transmission in response to the determination that the second portion of the DL transmission does not overlap with the CSI-RS.
12. The UE of claim 11 , wherein the first and second portions of the DL transmission are cancelled when a part of the DL transmission is not within a channel occupancy time (COT).
13. The UE of claim 12 , wherein the processor is further configured to monitor downlink control information (DCI),
wherein the COT is indicated in the DCI.
14. The UE of claim 11 , wherein the processor is further configured to set a timer for a predetermined duration,
wherein the first and second portions of the DL transmission are cancelled when a part of the DL transmission occasion is not within the predetermined duration.
15. The UE of claim 14 , wherein the timer comprises a timer introduced for switching groups of search space sets.
16. The UE of claim 11 , wherein the first and second portions of the DL transmission are cancelled when the DL transmission does not overlap with a set of DL transmissions with a gap.
17. The UE of claim 11 , wherein the first and second portions of the DL transmission are cancelled when the DL transmission is not between a detected downlink control information (DCI) and a scheduled physical downlink shared channel (PDSCH).
18. The UE of claim 11 , wherein the first and second portions of the DL transmission are cancelled when any part of the DL transmission is not within a transmission duration.
19. The UE of claim 18 , wherein the UE comprises a frame based equipment (FBE).
20. The UE of claim 11 , wherein the processor is further configured to monitor for a slot format indicator (SFI),
wherein the first and second portions of the DL transmission are cancelled when no SFI is detected.
