Extensive Summary of Agreements by Topic

Side Control Information

1. Beam Information:
• Beam information is recommended as side control information to improve NCR performance.
• Both fixed and adaptive beams can be considered for C-link and backhaul link.
• Beam correspondence is assumed for DL/UL of access link and backhaul link.
• For FR2, beam indication is beneficial for controlling NCR behavior; no evaluation results for FR1 yet.
2. ON-OFF Information:
• ON-OFF information is beneficial for energy efficiency and interference management.
• NCR-Fwd is expected to be "OFF" unless explicitly or implicitly indicated by gNB.
• For FR2, ON state is indicated implicitly via beam indication; for FR1, ON state is indicated via beam indication.
3. Timing Alignment:
• NCR-Fwd’s DL/UL timing aligns with NCR-MT’s DL/UL frame timing.
• Internal delay impacts timing relationships between DL/UL transmission and reception.
4. TDD UL/DL Configuration:
• Semi-static TDD UL/DL configuration is needed for C-link, backhaul link, and access link.
• Same TDD UL/DL configuration is assumed for all links if NCR-MT and NCR-Fwd operate in the same frequency band.
5. Power Control:
• Power control information is applicable for UL and DL forwarding links.
• Dynamic repeater gain/power control provides additional SINR gain over semi-static configurations.

Signaling for Side Control Information

1. L1/L2 Signaling:
• Dynamic and granular (symbol-level) side control information indication is supported.
• Both L1 (DCI-based) and L2/L3 (MAC-CE or RRC-based) signaling are considered for semi-static/periodic signals.
• Aperiodic beam indication is supported via DCI format 2_8.
2. Priority Handling:
• Priority order for beam indications: Aperiodic > Semi-persistent > Periodic.
• No conflict is expected between periodic or semi-persistent indications.
3. Beam Indication Granularity:
• Both slot-level and symbol-level granularity are recommended for time-domain resource indication.
• Semi-static and dynamic beam indications are supported.
4. Configuration Parameters:
• Maximum number of periodic beam indications: 32.
• Maximum supported number of beams: 64.
• Maximum number of symbols for time resource duration: 112.

NCR Behavior

1. Forwarding Behavior:
• NCR-Fwd does not perform forwarding in "OFF" state.
• Default behavior for flexible symbols is "OFF" unless dynamic DL/UL operation is supported.
2. Beam Failure Recovery:
• NCR-Fwd is OFF until beam failure recovery is completed in C-link.
3. Simultaneous Transmission:
• No specification impact for power sharing across NCR-MT and NCR-Fwd for simultaneous UL transmission.

Other Aspects

1. Control Plane Signaling:
• Legacy Rel-15 initial/random access procedures are supported for NCR-MTs in C-link.
• HARQ-ACK feedback for PDSCH carrying side control information is supported using legacy mechanisms.
2. Sounding Procedures:
• Legacy UE sounding procedures are supported for NCR-MT in C-link.
3. Beam Correspondence:
• Backhaul link beam follows the last MAC CE before BWP switching until a new MAC CE is received.
4. Abbreviations:
• NCR abbreviation added to specifications for clarity.
5. Cyclic Prefix:
• Time resource configuration for access link assumes the cyclic prefix of the active BWP.

Maintenance

1. Specification Alignment:
• Parameter names aligned across TS 38.213 and TS 38.306.
• Clarifications added for SCS and cyclic prefix assumptions.
2. Remaining Issues:
• No enhancement on DCI size for DCI 2_8; gNB ensures "DCI size budget."
• No conflict expected on AP-beam indication over overlapped time resources in a single DCI.
