Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resources, in a set of physical multicast channel symbols, for receiving a first type of reference signal and a second type of reference signal. The UE may receive one or more reference signal transmissions in accordance with the set of resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A network node and a user equipment (UE) may establish a connection between the UE and the network node of a non-terrestrial network. The UE may receive, from the network node and based on a type of orbit around Earth of the network node, a first value or the first value and a second value associated with a position or a velocity of the network node relative to a terrestrial-based reference. The UE and the network node may communicate based on the position or the velocity of the network node, or both. In some cases, the position or the velocity of the network node is based on an altitude of the network node, the first value, the second value, and a third value.

Abstract: Methods, systems, and devices for wireless communications are described that support multiplexing multicast and unicast feedback. A base station may provision different subsets of resources from a set of resources for multicast feedback message transmission based on channel metric(s) of a user equipment (UE). The set of resources may include a plurality of subsets of resources, with each subset of resources being associated with a corresponding channel metric or range of channel metrics associated with each UE receiving the multicast transmission. A UE may determine that a feedback indication is to be provided in response to the multicast transmission, and select a subset of resources from the plurality of subsets of resources based on its own channel metric. The UE may multiplex the multicast feedback, an indication of the selected subset, and unicast feedback in a multiplexed feedback transmission to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include establishing a connection between the UE and a network node of a non-terrestrial network, identifying, based on a synchronization failure event and while the UE is in a connected mode in accordance with establishing the connection, that a location failure condition has occurred for the connection, and performing, at least in part in response to the location failure condition, one or more actions of a location failure recovery procedure to restore a synchronization associated with the connection.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a mapping between downlink control information (DCI) codepoint values, multicast configurations, and unicast configurations. A DCI may then signal to the UE to apply one of a multicast configuration or a unicast configuration to receive a shared data channel transmission. For example, for a given DCI field of a group-common downlink control channel for multicast data, one or some DCI codepoint values may be associated with values configured for a multicast configuration, while remaining codepoints are associated with values configured for a unicast configuration. In some implementations, the UE may identify which multicast configuration or unicast configuration to apply based on the mapping, a type of data transmission scheduled by the DCI, specified values for the DCI codepoint values, whether the shared data channel transmission is a retransmission, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.
