Abstract
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.
Claims17
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.
A baseband processor for a user equipment (UE) configured to cause 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.
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), 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.
