  • Publication number: 20240073779
    Abstract: A method performed by a first network node for handling communication in a wireless communications network. The first network node receives a data packet with a header including an indicated destination, with a BAP address, and one or more values interpreted by the first network node as reserved or unknown. The first network node checks whether the first network node is an intended destination of the data packet based on the indicated destination in the header. With the proviso that the first network node is not the intended destination of the data packet and the BAP address is not included in the configured backhaul, BH, routing configuration, the first network node discards the data packet; and else, processes the data packet.

  • Patent number: 11902966
    Abstract: The embodiments herein relate to methods for SL SR/BSR handling. In one embodiment, there proposes a method in a wireless device, comprising: triggering a Sidelink (SL) Buffer Status Report (BSR) in response to data to be sent over the SL; triggering a Sidelink (SL) Scheduling Request (SR) for transmitting the SL BSR, wherein the SL BSR is intended to be transmitted by using a first uplink (UL) grant triggered by the SL SR; and cancelling the SL SR transmission if the SL BSR has been transmitted by using a second UL grant triggered by other sources. With embodiments herein, the LCP can be adapted based on QoS requirement and unsuitable cancel of sidelink BSR can be avoided, which improves performance of both UL and sidelink.

    Abstract: Embodiments herein relate to a method implemented by a wireless communication device. The wireless communication device transmits data to a radio node of a wireless communication network. The wireless communication device monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node. The wireless communication device retransmits the data to the radio node when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device refrains from retransmitting the data to the radio node when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device also refrains from retransmitting the data to the radio node when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.
