Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may detect a beam failure on an access link. The relay UE may transmit, to a network entity and responsive to the beam failure, information indicating that a UE, that uses the relay UE for relaying communications with the network entity, is to use a different relay UE. Numerous other aspects are described.

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 for detection of beam failure and beam failure recovery. A user equipment (UE) may perform measurements on one or more reference signals for one or more beams. In the event that one of the beams has a measurement that indicates a potential beam failure, the UE may increment a beam failure count (BFC) at a physical layer of the UE, and start a BFC timer. In the event that the BFC reaches a threshold value prior to expiration of the BFC timer, the UE may trigger a switch to a different active beam, provide a beam failure indication (BFI) to a higher layer of the UE, or both. A higher layer at the UE may autonomously adjust a BFI threshold for a number of BFIs that are needed to trigger a beam failure declaration to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a transmitting device may support receiver-specific network coding redundancy techniques. For example, a transmitting device may select a receiver-specific redundancy configuration for transmission to a particular receiver based on a quality of a link between the transmitting device and the receiving device. The transmitting device may select or calculate a user-specific redundancy for the link based on a received packet loss probability report, or may select the preferred redundancy configuration as indicated in a request received from the receiving device, or may network encode and transmit one or more initial transmissions according to a default redundancy configuration and increment or decrement the default redundancy based on feedback from the receiving device.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for signaling mechanisms associated with reporting information associated with multiple beam failure indicator (BFI) types via a beam failure detection (BFD) report. In some aspects, a user equipment (UE) may measure a periodic reference signal as part of a BFD procedure and may report a BFI if the UE measures that the reference signal fails to satisfy a threshold signal strength or quality. The UE may further detect or classify each reported BFI as one of multiple BFI types and may store information associated with respective numbers of the multiple BFI types in accordance with the detection or classification. In scenarios in which the UE declares beam failure, the UE may transmit a BFD report including the information associated with the respective numbers of the multipole BFI types.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit, to a plurality of user equipment (UE), a set of network encoded packets generated using a set of packets. A UE of the plurality of UEs may receive a subset of the set of encoded packets and may decode the subset to determine a first set of decoded packets. The UE may receive a second set of decoded packets from the plurality of UEs. The UE may transmit feedback to the network node that indicates the successfully decoded packets of the first and second sets. The network node may receive the feedback and may determine a subset of the set of packets that was successfully decoded for each UE providing the feedback. The network node may transmit an updated set of network encoded packets to the plurality of UEs.

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: Certain aspects of the present disclosure provide techniques for enhancing beam failure indications and detections. In particular, the present disclosure provides techniques for identifying and indicating reasons associated with beam failures. For example, in aspects, a user equipment (UE) may evaluate multiple beam failure indicator (BFI) trigger conditions based on beam failure detection (BFD) reference signal (RS) measurements. The UE logs different types of BFIs based on the evaluating. If a logged number of BFIs exceeds a threshold value within a measurement period, the UE declares a beam failure and transmits, to a network entity, an indication of the beam failure and a reason for the beam failure based on the different types of BFIs detected.

Abstract: Aspects relate to beam management reports that enable selection of best antenna panel and beam combinations for uplink transmissions from a user equipment (UE) when one or more antenna panels of the UE are subject to a maximum permissible exposure (MPE) limit. The UE receives a reference signal at a plurality of antenna panels, wherein the reference signal is received in different beams on each of the plurality of antenna panels. The UE determines N beams providing highest measured strengths of the reference signal on at least one of the plurality of antenna panels, wherein the MPE limit is to be applied to the at least one of the plurality of antenna panels for uplink transmissions. The UE transmits a beam management report including reduced highest measured strengths of the reference signal in the N beams to account for the MPE limit.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a control signal that indicates one or more parameters for a beam failure reporting procedure. The beam failure reporting procedure may be associated with a multi-path wireless connection for the first UE, which may include a first link between the first UE and a network entity and a second link between the first UE and a second UE. The first UE may monitor, as part of a multi-path beam failure recovery procedure, the first link for one or more signals associated with beam failure detection based on receiving the control signal. The first UE may transmit, via the first link or the second link, one or more messages in accordance with the beam failure reporting procedure based on monitoring. The one or more messages may include information associated with the one or more parameters.
