16.22.2 Identification, access and camping restrictions

A UE capability indicates that the UE is a 2Rx XR UE. A 2Rx XR UE does not identify itself in Msg1 or Msg3 during RACH procedure.

Network indicates whether access to a cell by 2Rx XR UEs is barred via system information. For a cell that operates in a frequency band where 4Rx antenna ports are mandated, presence of this indication in its system information indicates that the cell does not allow 2Rx XR UEs. In addition, an IFRI specific for 2Rx XR UEs can be provided in system information. Information on which neighbour frequencies 2Rx XR UEs are allowed to access can be provided in system information.

NOTE: It is up to the E-UTRA network, if possible, to avoid handover attempts of a 2Rx XR UE to a target NR cell not allowing 2Rx XR UEs as specified in TS 36.300 [2]. It is up to UE implementation, if possible, to recover from handover attempts to a target NR cell not allowing 2Rx XR UEs.
