Abstract:
High resolution angle of arrival (AoA) estimation and dynamic beam nulling may be provided. A beam direction with a highest received interference power may be determined, for example, by sweeping a beam. The beam may be a generic fixed beam. The generic fixed beam may have a predefined shape with a larger main lobe and narrow nulls. A null may be directed in the determined beam direction. A request for scheduling information may be sent to one or more transmit nodes. Scheduling information feedback may be received from the one or more transmit nodes. Beam shaping may be employed with nulling. The beam shaping may be employed based on the determined beam direction and/or the scheduling information feedback. A beam shape may be optimized and/or one or more nulls may be allocated based on the scheduling information feedback.
Abstract:
Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers. Packets targeted for FF may be divided into independently decodable CWs that may be transmitted in the next hop, for example, as soon as the destination is determined without waiting for an entire packet's arrival and/or for CRC verification. Low latency (e.g. FF) traffic may be indicated. CW-based FF may be extensible for an e2e RAN path from a WTRU to the last access node in a RAN. Intermediate metrics, a packet CRC and/or a per-CW CRC may be utilized for data integrity. HARQ and/or CW retransmission procedures may be implemented between network nodes for error handling.
