Link establishment procedures for ultra wideband sidelinks

A method for wireless communications at an extended reality device, comprising:

• performing an initial pairing procedure with an extended reality device via a narrow band, wherein the initial pairing procedure establishes an ultra wideband sidelink connection between a user equipment (UE) and the extended reality device;
• receiving control signaling via the narrow band indicating one or more sidelink resources of the ultra wideband sidelink connection for the extended reality device, wherein a local timeline for sidelink communications between the UE and the extended reality device associated with the one or more sidelink resources is translated from cellular timeline corresponding to the ultra wideband sidelink connection;
• and
• receiving a triggering signal, via the narrow band, initiating sidelink communications between the UE and the extended reality device via the one or more sidelink resources of the ultra wideband sidelink connection, the sidelink communications satisfying the local timeline according to the translation from the cellular timeline.

A user equipment (UE), comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
• perform an initial pairing procedure with an extended reality device via a narrow band, wherein the initial pairing procedure establishes an ultra wideband sidelink connection between the UE and the extended reality device;
• transmit control signaling via the narrow band indicating one or more sidelink resources of the ultra wideband sidelink connection for the extended reality device, wherein a local timeline for sidelink communications between the UE and the extended reality device associated with the one or more sidelink resources is translated from cellular timeline corresponding to the ultra wideband sidelink connection;
• and
• transmit a triggering signal, via the narrow band, initiating sidelink communications between the UE and the extended reality device via the one or more sidelink resources of the ultra wideband sidelink connection, the sidelink communications satisfying the local timeline according to the translation from the cellular timeline.
