  • Patent number: 11303397
    Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.

  • Patent number: 11296817
    Abstract: A method performed by a network node, for handling link adaption (LA) of a channel. The network node obtains a channel quality value for each Transmission Time Interval (TTI) in a set of TTIs. The network node estimates a probability that a specific channel quality will occur from the obtained channel quality values for the set of TTIs based on a distribution of channel quality values. The network node further determines a set of transmission parameters which optimizes a target function of LA, based on the estimated probability for the channel quality, wherein each set of transmission parameters is mapped to a channel quality which is required for a successful reception.

  • Patent number: 11297516
    Abstract: In order to maintain performance during wireless communication, a transmitting electronic device may concurrently and independently communicate redundant information to a receiving electronic device. In particular, information associated with a data stream may be communicated to the receiving electronic device using one or more channels by two radios using one or more wireless local area network communication protocols. The packets transmitted by the radios may preferentially include the same information. Moreover, the transmitting electronic device may attempt to maintain the redundant communication if a performance metric associated with the one or more channels degrades. For example, the transmitting electronic device may transfer communication to a different channel or may compress the information in the packets in the one or more channels if the throughput drops below a threshold value.

  • Patent number: 11271869
    Abstract: A method of multicasting packets by a forwarding element that includes several packet replicators and several egress pipelines. Each packet replicator receives a data structure associated with a multicast packet that identifies a multicast group. Each packet replicator identifies a first physical egress port of a first egress pipeline for sending the multicast packet to a member of the multicast group. The first physical egress port is a member of LAG. Each packet replicator determines that the first physical egress port is not operational and identifies a second physical port in the LAG for sending the multicast packet to the member of the multicast group. When a packet replicator is connected to the same egress pipeline as the second physical egress, the packet replicator provides the identification of the second physical egress port to the egress pipeline to send the packet to the multicast member. Otherwise the packet replicator drops the packet.
