Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARM) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.

Abstract: Methods, systems, and devices for wireless communications are described. In some non-terrestrial networks, the movement of satellites may result in the movement of cell coverage. A user equipment (UE) may experience changing cell coverage due to the movement of cell coverage, even if the UE is stationary. A UE may be configured to determine a cell is serving two or more earth-fixed tracking areas, determine whether to monitor paging resources of a first earth-fixed tracking area or a second earth-fixed tracking area, and monitor the selected paging resources. In some aspects, the UE may determine that a cell serves two or more earth-fixed tracking areas based on a received control message including multiple tracking area indicators. In some aspects, the UE may determine which paging resources to monitor based on a geographic position of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) configured as a drone-coupled wireless device may be configured to transmit a message indicating information relating to the drone-coupled wireless device (e.g., aerial state, non-aerial state, airborne status, drone capability, quality of service (QoS) requirements of a drone service) to a base station. The message may also carry a session connectivity request, which the base station may use to determine that the UE is a drone-coupled wireless device, establish a bearer appropriate for a subscription service of the UE (e.g., as indicated by the drone capability), and apply appropriate protocols for the UE.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites and base stations or gateways in a non-terrestrial network (NTN). Due to the large distances between transmitting devices and receiving devices in a NTN, timing adjustments to account for propagation delay communications links via a satellite may include a propagation delay between a UE and a satellite, a propagation delay between a base station and a satellite, as well as a variation in the propagation delays due to movement of the satellite. In accordance with various techniques discussed herein, a UE may account for variation in propagation delay, in addition to determined propagation delay, when determining an uplink timing for uplink communications via a satellite.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.

Abstract: Certain aspects of the present disclosure relate generally to communication systems, and more particularly, to enhanced reporting by user equipment (UE). An example method generally includes receiving an information request from a network node and in response, sending a message to the network node, wherein the message comprises information that allows the network node to determine a starting coverage enhancement (CE) level of the UE.

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 wireless device, such as a user equipment (UE), may receive a configuration of a wake-up signal periodicity and perform discontinuous monitoring for a plurality of wake-up signals based at least in part on the wake-up signal periodicity. In some cases, the UE may perform a radio resource management (RRM) measurement according to an RRM measurement periodicity that corresponds to the wake-up signal periodicity. In such cases, the UE may monitor for paging messages to receive paging information, or updates to system information, during one or more wake-up signal occasions that correspond to the RRM measurement periodicity. For instance, paging information may be received while the UE is performing RRM measurements, where paging message may be monitored for based on the wake-up signal periodicity.

Abstract: Methods, systems, and devices for wireless communications are described. More specifically, the methods, systems, and devices support extending capability signaling to support higher modulation order baseband capability, such as higher order quadrature amplitude modulation (QAM), for example, 1024QAM. By way of example, a user equipment (UE) may transmit UE capability information to a base station (e.g., eNodeB (eNB), next-generation NodeB ((gNB)) in a connection establishment procedure. The UE capability information may include a UE category identifier and a baseband capability parameter. The baseband capability parameter may indicate a scaling factor for a first modulation order of a plurality of available modulation orders. The UE may communicate with the base station over multiple layers using corresponding modulation orders for the multiple layers.
