Methods of signaling directional and omni COT for frequencies between 52.6 GHz and 71 GHz
A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.
1. A method for a User Equipment (UE), the method comprising:
receiving a system information block (SIB) via radio resource control (RRC) signaling, the SIB comprising a listen before talk (LBT) configuration element;
decoding the SIB to determine the LBT configuration element;
sensing a channel for availability for transmissions based on the LBT configuration element in the SIB; and
sending a transmission when the channel is available.
2. The method of claim 1 , wherein the LBT configuration element comprises a parameter that indicates that the UE is to apply LBT.
3. The method of claim 1 , wherein the LBT configuration element is for a frequency range comprising 52.6 gigahertz (GHz) to 71 GHz.
4. The method of claim 1 , further comprising receiving a Downlink Control Information (DCI) message, the DCI message indicating a LBT procedure type.
5. The method of claim 4 , wherein sensing the channel for the availability comprises performing a procedure associated with the LBT procedure type.
6. The method of claim 1 , wherein the LBT configuration element is configured if LBT applies.
7. A user equipment (UE) comprising:
a baseband processor;
a memory storing instructions that, when executed by the baseband processor, configure the UE to:
receive a system information block (SIB) via radio resource control (RRC) signaling, the SIB comprising a listen before talk (LBT) configuration element;
decode the SIB to determine the LBT configuration element;
sense a channel for availability for transmissions based on the LBT configuration element in the SIB; and
send a transmission when the channel is available.
8. The UE of claim 7 , wherein the LBT configuration element comprises a parameter that indicates that the baseband processor for the UE is to apply LBT.
9. The UE of claim 7 , wherein the LBT configuration element is for a frequency range comprising 52.6 gigahertz (GHz) to 71 GHz.
10. The UE of claim 7 , wherein the instructions further configure the UE to receive a Downlink Control Information (DCI) message, the DCI message indicating a LBT procedure type.
11. The UE of claim 10 , wherein the instructions further configure the UE to sense the channel for the availability by performing a procedure associated with the LBT procedure type.
12. The UE of claim 10 , wherein the LBT configuration element is configured if LBT applies.
13. A method for a network node, the method comprising:
configuring a system information block (SIB), the SIB comprising a listen before talk (LBT) configuration element;
sending the SIB, to a User Equipment (UE), via radio resource control (RRC) signaling;
receiving a transmission from the UE when a channel is available based on the LBT configuration element in the SIB.
14. The method of claim 13 , wherein the LBT configuration element comprises a parameter that indicates that the UE is to apply LBT.
15. The method of claim 13 , wherein the LBT configuration element is for a frequency range comprising 52.6 gigahertz (GHz) to 71 GHz.
16. The method of claim 13 , further comprising sending a Downlink Control Information (DCI) message, the DCI message indicating a LBT procedure type.
17. The method of claim 16 , wherein the LBT configuration element is configured if LBT applies.
