name: SBFD
full_form: Subband non-overlapping Full Duplex
context: SBFD operation at gNB for UEs was studied under the following assumptions, - SBFD operation within a TDD carrier. - SBFD scheme within a single configured DL and UL BWP pair with aligned center frequencies, and - Up to one UL subband for SBFD operation in an SBFD symbol (excluding legacy UL symbol) within a TDD carrier. RAN1 concluded SBFD operation Option 4 is feasible for RRC_CONNECTED state from the RAN1 specification perspective, where SBFD operation Option 4 assumes - Both time and frequency locations of subbands for SBFD operation are known to SBFD aware UEs. - UE behaviors for non-SBFD aware UEs follow existing specifications. - From RAN1 perspective, new UE behaviors can be introduced for SBFD aware UEs based on the time and frequency locations of subbands for SBFD operation. Non-SBFD aware UEs, including legacy UEs, and SBFD aware UEs can coexist in cells with SBFD operation at gNB side from RAN1 specification point of view. To support SBFD operation Option 4 for RRC_CONNECTED
description: Subband non-overlapping Full Duplex (SBFD) is a technology used in 5G networks to enable full duplex communication within a single frequency band, allowing for simultaneous transmission and reception of data. It operates by dividing the frequency band into subbands that do not overlap with each other.
explanation: The context describes SBFD as a specific operational scheme studied for its feasibility in 5G networks. This indicates it's a technological approach or standard used in telecommunications, thus falling under the 'Technology' category.
