Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit, to a set of user equipment (UE), a set of network encoded packets generated using a set of packets. A UE of the set of UEs may receive subsets of network encoded packets from the network node and from UEs of the set of UEs forwarding network encoded packets. The UE may decode the subsets of network encoded packets and may determine a set of successfully decoded packets. The UE may transmit feedback to the network node that indicates successfully received or decoded packets. 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 generate an updated set of network encoded packets and may transmit the updated set to the set of UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, at least one reference signal associated with at least one beam. The UE may generate a beam failure indicator (BFI) based at least in part on one or more measurements of the at least one reference signal at the UE. The BFI may be selected (e.g., by the UE or by the base station) from two or more types of BFI based at least in part on one or more measurements associated with the at least one beam at the base station. Numerous other aspects are described.

Abstract: Techniques and apparatus for using downlink control information (DCI) to avoid hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One example technique involves a user equipment (UE) receiving an indication of a plurality of SPS configurations, each SPS configuration allocating the UE with a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. Information for resolving a conflict between a first HARQ process ID associated with a first SPS occasion of a first of the plurality of SPS configurations and a second HARQ process ID associated with a second SPS occasion of a second of the plurality of SPS configurations is received. The first SPS occasion occurs prior to the second SPS occasion. The conflict is resolved based on the information.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives “candidate” Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.

Abstract: Methods, systems, and devices for wireless communications are described for scheduled communications in which multiple different communication instances are scheduled between a user equipment (UE) and a base station. Different communication parameters for different communication instances may be selected based on reported channel conditions between the UE and the base station. Subsequent to a report of channel conditions results in chanced communication parameters, the UE may blind decode a one or more scheduled communications using multiple candidate sets of decoding hypotheses to identify a first candidate set of decoding parameters that is used for the first scheduled communication. Such techniques provide that communication parameters may be adjusted based on channel conditions, and a UE may decode a communication in the event that the base station does not successfully receive a measurement report and continues transmissions using a prior set of parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information specifying similarity data to be provided in a Layer 1 (L1) report. The UE may transmit, to the base station and based at least in part on receiving the configuration information, the L1 report. The L1 report indicates a measure of similarity between a current condition of the UE and a past condition of the UE associated with a past event associated with the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and user equipment (UE) may support network coded communications on a sidelink connection. The base station may configure UEs with network coding configurations. The network coding configuration may include one or more sets of network coding parameters. The base station may configure a first UE to send network coded information on the sidelink to a second UE. The network coded information may be generated based on data packets which were unsuccessfully decoded by the second UE. By transmitting network coded information on a sidelink, the second UE may efficiently obtain data packets which were unsuccessfully decoded from the base station.

Abstract: This disclosure provides systems, methods and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a broadcast sidelink communication that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the broadcast sidelink communication to the second UE.
