Existence of periodic/semi-static signals and channels outside of channel occupancy time (cot)

Abstract

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 channel status information (CSI)-reference signal (RS); determining, by the UE, whether to cancel the CSI-RS; and cancelling, by the UE, the CSI-RS if it is determined that the CSI-RS 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 channel status information (CSI)-reference signal (RS);   determining, by the UE, whether to cancel the CSI-RS; and   cancelling, by the UE, the CSI-RS if it is determined that the CSI-RS is to be cancelled.   
     
     
         2 . The method of  claim 1 , wherein the portion of the CSI-RS is determined to be cancelled when a part of the CSI-RS 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 reception of a portion of a downlink (DL) transmission configured by a higher layer is determined to be cancelled when a part of the DL transmission 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 a downlink (DL) transmission is determined to be configured by a higher layer if the DL transmission is fully overlapped with a set of DL transmissions. 
     
     
         7 . The method of  claim 1 , wherein the CSI-RS is determined to be cancelled when the CSI-RS is not between a detected downlink control information (DCI) and a scheduled physical downlink shared channel (PDSCH). 
     
     
         8 . The method of  claim 1 , wherein reception of a DL transmission configured by a higher layer is 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 CSI-RS is determined to be cancelled when no SFI is detected.   
     
     
         11 . A user equipment (UE), comprising:
 a transceiver;   a memory; and   a processor configured to:
 receive, from the network, a channel status information (CSI)-reference signal (RS); 
 determine whether to cancel the CSI-RS; and 
 cancel the CSI-RS if it is determined that the CSI-RS is to be cancelled. 
   
     
     
         12 . The UE of  claim 11 , wherein the portion of the CSI-RS is determined to be cancelled when a part of the CSI-RS 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), and
 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, and
 wherein reception of a portion of a downlink (DL) transmission configured by a higher layer is determined to be cancelled when a part of the DL transmission 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 a DL transmission is determined to be configured by a higher layer if the DL transmission is fully overlapped with a set of DL transmissions. 
     
     
         17 . The UE of  claim 11 , wherein the CSI-RS is determined to be cancelled when the CSI-RS is not between a detected downlink control information (DCI) and a scheduled physical downlink shared channel (PDSCH). 
     
     
         18 . The UE of  claim 11 , wherein reception of a DL transmission configured by a higher layer is 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), and
 wherein the CSI-RS is determined to be cancelled when no SFI is detected.
