Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that indicates one or more parameters pertaining to reception of paging early indications (PEIs). The UE may receive a PEI from the base station in accordance with the one or more parameters. The UE may determine, based on the PEI, whether the UE is scheduled to receive a multicast paging message from the base station in a subsequent paging occasion (PO). If the UE is scheduled to receive a multicast paging message, the UE may monitor for the multicast paging message in the subsequent PO. Otherwise, the UE may enter a low-power state during the subsequent PO, which may result in greater power savings at the UE. Aspects of the present disclosure may provide for improved multicast paging operations between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A set of reference signal resources that are configured for sounding reference signal transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of reference signal resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel and transmit sounding reference signals over one of the shared reference signal resources that is associated with the set of channel state information determined by the UE. A base station that receives the sounding reference signal may transmit a subsequent multicast transmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied sounding reference signal resource.

Abstract: In an embodiment, a network component (e.g., eNB) of a terrestrial wireless communication subscriber network determines whether a drone-coupled user equipment (UE) is engaged in a flying state based upon one or more wireless signals transmitted by the drone-coupled UE. The determination can occur in a variety of ways, such as based on a message from the drone-coupled UE itself (e.g., an express flying-state notification from the drone-coupled UE, a request particular to a flying state, a measurement reporting message, an identifier used by the drone-coupled UE, uplink signal strength measurement(s) or uplink AoA measurements, whether any intervening base station(s) were skipped over in conjunction with a handoff of the drone-coupled UE, etc.).

Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: Certain aspects of the present disclosure relate to techniques for secondary cell (SCell) configuration signaling and activation procedures. For example, certain aspects provide a method for activating at a user equipment one or more secondary cells of a target base station. The method includes transmitting a measurement report for the one or more secondary cells. The method includes receiving secondary cell activation information for the user equipment from the target base station prior to completion of connection of the user equipment to the target base station, wherein the secondary cell activation information indicates the one or more secondary cells. The method includes activating the one or more secondary cells at the user equipment after completion of connection to the target base station.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.
