6.6 Beam correspondence
38.101-23GPPNRPart 2: Range 2 StandaloneRelease 17TSUser Equipment (UE) radio transmission and reception
6.6.1 General
Beam correspondence is the ability of the UE to select a suitable beam for UL transmission based on DL measurements with or without relying on UL beam sweeping. Unless explicitly addressed in subclauses below, the beam correspondence requirement is fulfilled if the UE meets the corresponding minimum peak EIRP and spherical coverage requirement for that power class with its autonomously chosen UL beams and without uplink beam sweeping.

6.6.4 Beam correspondence for power class 3
6.6.4.1 General
The beam correspondence requirement for power class 3 UEs consists of three components: UE minimum peak EIRP (as defined in Clause 6.2.1.3), UE spherical coverage (as defined in Clause 6.2.1.3), and beam correspondence tolerance (as defined in Clause 6.6.4.2). The beam correspondence requirement is fulfilled if the UE satisfies one of the following conditions, depending on the UE’s beam correspondence capability IE beamCorrespondenceWithoutUL-BeamSweeping, as defined in TS 38.306 [14]:
UEs supporting FR2-2 shall support beamCorrespondenceWithoutUL-BeamSweeping.

Such a UE is considered to have met the beam correspondence tolerance requirement.
– If beamCorrespondenceWithoutUL-BeamSweeping and beamCorrespondenceSSB-based-r16 are supported, the UE shall meet the minimum peak EIRP requirement according to Table 6.2.1.3-1 and spherical coverage requirement according to Table 6.2.1.3-3 using the side conditions for SSB based enhanced beam correspondence requirements as defined in Clause 6.6.4.3.2.

– If beamCorrespondenceWithoutUL-BeamSweeping is not present, the UE shall meet the minimum peak EIRP requirement according to Table 6.2.1.3-1 and spherical coverage requirement according to Table 6.2.1.3-3 with uplink beam sweeping. Such a UE shall meet the beam correspondence tolerance requirement defined in Clause 6.6.4.2 and shall support uplink beam management, as defined in TS 38.306 [14].
– If beamCorrespondenceWithoutUL-BeamSweeping is not present and beamCorrespondenceSSB-based-r16 is supported, the UE shall meet the minimum peak EIRP requirement according to Table 6.2.1.3-1 and spherical coverage requirement according to Table 6.2.1.3-3 with uplink beam sweeping using the side conditions for SSB based enhanced beam correspondence requirements as defined in Clause 6.6.4.3.2. Such a UE shall meet the beam correspondence tolerance requirement defined in Clause 6.6.4.2 and shall support uplink beam management, as defined in TS 38.306 [14].

Such a UE shall meet the beam correspondence tolerance requirement defined in Clause 6.6.4.2 and shall support uplink beam management, as defined in TS 38.306 [14].
6.6.4.2 Beam correspondence tolerance for power class 3
The beam correspondence tolerance requirement ∆EIRPBC for power class 3 UEs is defined based on a percentile of the distribution of ∆EIRPBC, defined as ∆EIRPBC = EIRP2 – EIRP1 over the link angles spanning a subset of the spherical coverage grid points, such that
– EIRP1 is the total EIRP in dBm calculated based on the beam the UE chooses autonomously (corresponding beam) to transmit in the direction of the incoming DL signal, which is based on beam correspondence without relying on UL beam sweeping.
– EIRP2 is the best total EIRP (beam yielding highest EIRP in a given direction) in dBm which is based on beam correspondence with relying on UL beam sweeping.
– The link angles are the ones corresponding to the top Nth percentile of the EIRP2 measurement over the whole sphere, where the value of N is according to the test point of EIRP spherical coverage requirement for power class 3, i.e. N = 50.
For power class 3 UEs, the requirement is fulfilled if the UE’s corresponding UL beams satisfy the maximum limit in Table 6.6.4.2-1.

6.6.8.3.3 Side Condition for CSI-RS based enhanced Beam Correspondence requirements
The beam correspondence requirements for beam correspondence based on CSI-RS are only applied under the following side conditions:
– The downlink reference signals including both SSB and CSI-RS are provided.
– The reference measurement channel for beam correspondence is fulfilled according to the CSI-RS configuration in Annex A.3.
– For beam correspondence, conditions for L1-RSRP measurements are fulfilled according to Table 6.6.8.3.1-2 and SSB signal is provided according to Table 6.6.8.3.3-1.

NOTE 1: For UEs that support multiple FR2 bands, the Minimum SSB_RP values for all angles are increased by MBS,n, the UE multi-band relaxation factor in dB specified in clause 6.2.1. NOTE 2: Values specified at the radiated requirements reference point to give minimum SSB Ês/Iot, with no applied noise. |

6.6.8.4 Applicability
For UEs supporting more than one type of beam correspondence, the following applicability rules apply:
– If a UE meets enhanced beam correspondence requirements either based on SSB or based on CSI-RS, it is considered to have met the beam correspondence requirements based on SSB and CSI-RS.
– For a UE supporting either SSB based or CSI-RS based enhanced beam correspondence, the UE shall meet the supported enhanced beam correspondence requirements.
– For a UE supporting both SSB based and CSI-RS based enhanced beam correspondence, the UE shall meet both SSB based and CSI-RS based enhanced beam correspondence requirements and the following applicability rules for verifying the requirements apply:
– The enhanced beam correspondence requirements shall be verified with the SSB based enhanced beam correspondence side conditions in clause 6.6.8.3.2. If UE meets the SSB based enhanced beam correspondence requirements using the side conditions in clause 6.6.8.3.2 and meets the minimum peak EIRP requirement as defined in clause 6.2.1.7 using the CSI-RS based side conditions in clause 6.6.8.3.3, where the link direction is determined in the SSB based enhanced beam correspondence test, the UE is considered to have met both the SSB based and CSI-RS based enhanced beam correspondence requirements.
– Otherwise, if UE does not meet the minimum peak EIRP requirement as defined in clasue 6.2.1.7 using the CSI-RS based side conditions in clause 6.6.8.3.3, the enhanced beam correspondence requirements shall be further verified for the UE with the CSI-RS based enhanced beam correspondence side conditions in clause 6.6.8.3.3.
