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: Methods, systems, and devices for wireless communications are described. The described techniques may enhance coverage by supporting repetitions of a random access request. A user equipment (UE) may receive, from a network entity, a synchronization signal block (SSB) message. The UE may measure the SSB message in order to determine signal metric, such as reference signal received power (RSRP). Based on the RSRP of the SSB, the UE may determine to transmit a set of repetitions of a random access request. The UE may then monitor a resource of a downlink control channel for a random access response from the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may transmit a sidelink request to a second UE. The sidelink request may indicate a set or a segment of the data resources. A second UE may transmit a positive sidelink response indicating that the set or the segment of resources is available for reservation, or may refrain from transmitting a positive sidelink response if the set or the segment of the data resources is unavailable for reservation. A third UE may transmit a negative sidelink response indicating that the set or the segment of the data resources is unavailable for reservation, or may refrain from transmitting a negative sidelink response if the set or the segment of the data resources is available for reservation. If the requested data resources are available, then the first UE may transmit a sidelink confirmation reserving the requested data resources.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.

Abstract: Device and techniques for wireless communications are described. A user equipment (UE) may switch from a first bandwidth part (BWP) configuration to a second BWP configuration based on a trigger for transitioning from a first activity state to a second activity state with respect to a cell group. The trigger may be an expiration of a timer at the UE, or the UE may receive control signaling indicating the transition. The second BWP configuration may be based on a mode configured at the UE associated with the second activity state. The configured mode may indicate one or more measurements the UE is to perform while in the second activity state. In some examples, the BWP configuration may include configured BWPs based on the indicated measurements of the configured mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a connection with a base station based at least in part on a synchronization signal block from the base station, wherein the synchronization signal block comprises at least a first synchronization signal. The UE may identify a configuration for a transmission pattern for the first synchronization signal to be transmitted by the base station. The UE may receive one or more instances of the first synchronization signal according to the transmission pattern for the first synchronization signal. The UE may modify the established connection with the base station based at least in part on the received one or more instances of the first synchronization signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling including a set of parameters. The set of parameters may include one or more thresholds associated with initiating aperiodic beam failure detection (BFD) reference signals (RSs). The UE may receive a set of periodic BFD-RSs. In some examples, the UE or the base station may determine that a triggering threshold is satisfied. In some cases, the UE may determine that the set of periodic BFD-RSs satisfies a consecutive beam failure indication (BFI) threshold, a cumulative BFI threshold, or the like. In some cases, a base station may determine that the set of periodic BFD-RSs satisfies a channel quality threshold. The UE may receive a set of one or more aperiodic BFD-RSs based on whether the triggering threshold is satisfied.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, via a communication link between the first UE and a base station, radio resource control (RRC) signaling which configures a relay communication sidelink for communicating message traffic between the first UE and a second UE for relay to the base station. The first UE may receive a control message via layer one (L1) signaling or layer two (L2) signaling which activates the relay communication sidelink configured by the RRC signaling. The first UE may then communicate, via the relay communication sidelink, a message for relay to or from the base station by the first UE or the second UE based on the control message.

Abstract: Methods, systems, and devices for wireless communication are described related to timer-based sidelink discontinuous reception (DRX). A UE may receive configuration information for a sidelink DRX mode from a base station or another UE, which may indicate one or more parameters of the sidelink DRX mode. When operating in the sidelink DRX mode, a group of UEs may have shared active durations and inactive durations for coordinating sidelink communications. In a timer-based sidelink DRX mode, if a UE receives or transmits a sidelink communication, the UE may initiate an inactivity timer, and the UE may continue to monitor a sidelink channel for other sidelink communications while the timer is running. One or more rules may govern the operation of an inactivity timer with respect to the shared inactive durations.
