    Abstract: Methods, systems, and devices for wireless communications are described. A first network entity may establish a sidelink connection with a first user equipment (UE). The first network entity may detect sidelink communications including sidelink data from the first UE, and may forward the detected sidelink data to a second network entity via a sidelink interface or a backhaul link. The second network entity may transmit the sidelink data to a second UE via a sidelink connection between the second network entity and the second UE.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and multiple network coding devices may communicate to reduce multiple network coding devices accepting a same take over request message from the UE for a given data packet. In some examples, the multiple network coding devices may determine respective backoff periods to wait before accepting the take over request message such that each backoff period is different for each network coding device. In some examples, the UE may receive respective broadcast messages from each of the multiple network coding devices that indicate a network coding capability parameter, and the UE may select a network coding device based on the received capability parameter. In some examples, a network coding device may transmit an indication of packet overload and refrain from accepting a take over request message.

    Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure relate to an in-coverage user equipment (UE) relaying broadcast messages to out-of-coverage UEs using one or more messaging techniques over a sidelink channel. The in-coverage UE may monitor for broadcast messages to relay the broadcast messages to out-of-coverage UEs. In some cases, the in-coverage UE may determine to relay broadcast messages to the out-of-coverage UEs based on one or more metrics. Additionally, the in-coverage UE may determine whether the broadcast message is to be included in a groupcast, broadcast, or unicast signaling. Based on the determination to relay broadcast messages, as well as whether the alert message is to be included in a groupcast, broadcast, or unicast signaling, the in-coverage UE may leverage sidelink communications to relay broadcast messages to the out-of-coverage UEs.

    Abstract: The techniques described herein provide procedures at user equipment (UEs) for performing channel state information (CSI) reporting and sounding reference signal (SRS) transmissions based on an ultra-reliable low latency communication (URLLC) block error rate (BLER) target and for reliably receiving PDCCH transmissions. For CSI reporting, a UE may be configured to generate a CSI report based on a BLER target and on received CSI reference signals (CSI-RSs), where the CSI-RSs may be transmitted on one or more groups of quasi co-located antenna ports. For SRS transmissions, a UE may be configured to transmit SRS based on an SRS configuration determined based on a BLER target. For receiving PDCCH transmissions, a UE may be configured to receive and combine DCI received from multiple base stations.

    Abstract: Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) to be scheduled by a scheduler UE in a sidelink system may transmit a first scheduling request (SR) to request sidelink resources. The UE may transmit the first SR via a set of feedback resources. The scheduler UE may transmit, to the UE, a sidelink control message to schedule a sidelink transmission. The sidelink control message may indicate a set of feedback resources mapped to the sidelink transmission. The UE may transmit the scheduled sidelink transmission based on the sidelink control message and may request additional sidelink resources. The UE may transmit a second SR, where the second SR is transmitted via the set of feedback resources mapped to the sidelink transmission.
