Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify one or more user equipments (UEs) subscribed to receive broadcast transmissions. The base station may determine a first subset of the UEs is to receive broadcast transmissions via a direct link and a second subset of the UEs is to receive the packets from the broadcast transmission via a sidelink connection based on selection criteria. The base station may transmit an indication that the broadcast transmissions are to be received via either the direct link or sidelink connection to at least one of the first subset of UEs or the second subset of UEs. The base station may transmit the broadcast transmissions to the first subset of UEs via direct links, and the first subset of UEs may transmit the broadcast transmissions to one or more other UEs via sidelink connections.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a periodic reference signal from a base station and may measure the periodic reference signal as part of a beam failure detection (BFD) procedure. To detect a beam failure, the UE may autonomously select a beam failure indicator (BFI) counting scheme from a set of BFI counting schemes and may increment a BFI count in accordance with the selected BFI counting scheme and based on measuring the reference signal. The different BFI counting schemes of the set of BFI counting schemes may feature different techniques or methods for incrementing the BFI count per one or more BFI reports. As such, the UE may selectively choose how to weight different sets of one or more BFI reports in terms of contribution to the BFI count, which may improve BFD detection at the UE.

Abstract: Methods, systems, and devices for wireless communications are described that provide for interference-aware beam failure detection procedures. One or more beam failure parameters may be adjusted based on a likelihood of temporary interference being present for a communications beam. The beam failure parameters may include beam failure indication (BFI) counts or count thresholds that may be adjusted based on a likelihood of BFIs being the result of temporary interference. Additionally or alternatively, one or more measurement thresholds that trigger a BFI may be adjusted based on a likelihood of a presence of temporary interference.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, a configuration indicating a channel quality threshold that the UE may use to identify an interference-based beam failure indicator type. The UE may receive a reference signal for performing one or more signal measurements in accordance with the configuration. Based on the one or more signal measurements and the channel quality threshold, the UE may report an indication of the type of beam failure indicator to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may identify a set of one or more packets for broadcast to a set of one or more user equipments (UEs) and transmit a set of one or more network encoded packets based on the set of one or more packets. The UEs may each rebroadcast one or more successfully received network encoded packets via sidelink communications. Each UE may report to the original transmitter via feedback indicating the one or more successfully received packets at each UE. The transmitter may generate an updated set of one or more network encoded packets based on the feedback from the UEs. The transmitter may continue to update and transmit the updated set of one or more network encoded packets based on feedback until the transmitter determines that each UE has recovered the set of one or more packets.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit sets of network coding encoded packets user equipments (UEs), and each set of network coding encoded packets may be associated with a redundancy overhead. The base station may dynamically identify the redundancy overhead for transmitting sets of network coding encoded packets to each UE based on a failure rate associated with a previous transmission of network coding encoded packets to that UE. For example, the base station may determine a failure rate associated with a transmission of a first set of network coding encoded packets and may identify a redundancy overhead associated with one or more second sets of network coding encoded packets based on the determined failure rate. In some cases, the base station may identify different redundancy overheads for transmissions of network coding encoded packets to different UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may perform a first encoding operation on source packets that generates a first set of network coding encoded packets and may broadcast the first set of network coding encoded packets for reception by a plurality of receivers. The transmitter may receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that a first subset of network coding encoded packets were received by at least one of the plurality of receivers, the feedback information further indicating that one or more receivers of the plurality of receivers did not successfully recover all of the plurality of source packets. The transmitter may broadcast a second set of network coding encoded packets that does not include any of the first subset of network coding encoded packets. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate with a second UE using a sidelink channel and a first beam. The UE may transmit a sidelink beam report associated with the first beam to a network entity. The UE may receive sidelink configuration information from the network entity that indicates to change from using the sidelink channel and the first beam to using the sidelink channel and a second beam. The UE may communicate with the second UE using the sidelink channel and the second beam. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may identify a set of packets (e.g., from a packet pool) that are scheduled for broadcast to a plurality of user equipments (UEs) and transmit a set of network encoded packets based on the set of packets. The network node may receive feedback from one or more of the plurality of UEs, and the feedback may indicate successfully decoded packets by each of the one or more UEs. Based on the feedback, the network node may identify an updated set of packets and transmit the updated set. The transmitter may continue to update and transmit based on feedback until the feedback indicates that updated set of packets is empty.
