Summary of Agreements by Topic

Reduced Maximum UE Bandwidth

1. Initial DL BWP Configuration:
• RedCap UEs can operate in a separate initial DL BWP that includes CD-SSB and the entire CORESET#0.
• For FR1 and FR2, RedCap UEs in connected mode can operate in a separate initial DL BWP without CD-SSB if they support FG 28-1a.
• NCD-SSB periodicity is not required to match CD-SSB periodicity, but periodicity of NCD-SSB must be no less than CD-SSB.
2. PUCCH Resource Configuration:
• When frequency hopping for common PUCCH resources is deactivated, all PUCCH resources are mapped to one side of the UL BWP, configurable via SIB.
• Additional PRB offset values are defined for PUCCH resource mapping.
3. SSB Handling:
• RedCap UEs in idle/inactive mode do not expect the initial DL BWP to include SS/PBCH blocks unless monitoring Type2-PDCCH CSS set.
• In connected mode, RedCap UEs can operate in active DL BWPs without receiving SS/PBCH blocks if they indicate capability to do so.

Reduced Number of Rx Branches

1. Capability Indication:
• The number of Rx branches for RedCap UEs is implicitly indicated via the maxNumberMIMO-LayersPDSCH parameter in the existing UE capability framework.

Duplex Operation

1. HD-FDD Handling:
• HD-FDD RedCap UEs prioritize SSB over dynamically scheduled UL transmissions, including Msg3 retransmissions and PUCCH for Msg4/MsgB.
• DL-UL collision handling for HD-FDD operation is applied after intra-UE multiplexing/prioritization.
2. Collision Handling:
• HD-FDD RedCap UEs do not support partial cancellation in Rel-17.
• For unpaired spectrum, RedCap UEs do not expect configurations where the center frequency for initial DL BWP differs from initial UL BWP.

Small Data Transmission (SDT)

1. SDT in BWP Without SSB:
• RedCap UEs performing random access in idle/inactive state in a RedCap-specific initial DL BWP without CD-SSB or NCD-SSB should apply CD-SSB for PRACH occasion validation.
2. CG-SDT:
• CG-SDT in a RedCap-specific separate initial BWP without CD-SSB but with NCD-SSB can be revisited in future discussions.

NCD-SSB Handling

1. QCL Relationship:
• SS/PBCH blocks provided by NonCellDefiningSSB and those used to obtain SIB1 have the same QCL properties if they share the same index.
2. Collision Handling:
• Collision handling between uplink transmissions and SS/PBCH blocks provided by NonCellDefiningSSB is the same as for SS/PBCH blocks indicated by ssb-PositionsInBurst.

Msg1/MsgA Retransmission Timeline

1. Timeline Clarification:
• No specification change is made to the Msg1/MsgA retransmission timeline in Rel-17. Existing timelines do not account for time required to measure SS/PBCH blocks outside the active DL BWP.

General Agreements

1. Layer-1 UE Features:
• RedCap UEs support all mandatory Layer-1 UE features without capability signaling unless stated otherwise.
2. Procedures for HD-UE:
• Procedures for HD-UE are the same as described for other UEs unless stated otherwise.
3. Validation of PRACH/PUSCH Occasions:
• PRACH occasion validation for RedCap UEs in TDD without any SSB should apply CD-SSB.

This summary captures the key agreements across various topics related to the support and maintenance of Reduced Capability NR Devices (RedCap).
