SEMI-PERSISTENT SCHEDULING DESIGNS FOR RELAYING

Abstract:

Aspects relate to semi-persistent scheduling (SPS) designs for relay communication in sidelink networks. A scheduling entity, such as a base station and/or sidelink device, may configure an SPS configuration for relaying a packet from a source device to a destination device (e.g., the base station or destination sidelink device) via at least one relay device in a relay sidelink tunnel. SPS information associated with the SPS configuration may be provided to the source device and relay device(s). The SPS information may include, for example, periodic transmit occasions for the source device and the relay device(s). The periodic transmit occasions may include periodic uplink occasions and/or periodic sidelink occasions for groupcast and/or unicast relay transmission. Periodic feedback occasions may further be configured for providing feedback information (e.g., an acknowledgement or negative acknowledgement).
