Each RN can determine a slot format of a link under the RN and signal the slot format.
To support this, each RN can provide the following information to a donor NB (gNB or RN).
-
- Information about a neighbor node that interferes when each RN performs UL operation
The corresponding information may be for each link because interferers may be different for links. For example, an interferer for an access link, an interferer for a donor-RN link and an interferer for an RN-relay node link may be different.
A measurement result through RSRP with respect to each neighboring node can be signaled.
-
- Resource configuration for measurement between neighboring cells (e.g., CSI-RS configuration)
- SR resource information or periodic uplink resource information (period & offset) configured for UE
- Periodic downlink resources (e.g., SSB period & offset) configured for UE
- Information about a UE may be configured by each RN according to determined SFI.
- Backhaul links are necessary to transmit such information, and information may be transmitted at a predetermined timing or such timing may be set by a donor gNB.
- Alternatively, when SFI for an access link differs from that of the donor, SFI information can be transmitted. The corresponding SFI can be limited to semi-statically configured SFI.
