Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a wakeup signal (WUS) from a network node, such as a base station, before listening for a paging message. The UE may assume a maximum duration (Wmax) for the WUS based on a dependency on variables associated with the base station and WUS. In some cases, the UE may determine not to monitor a WUS for the Wmax and may engage in an early termination based on the determination. That is, the UE may monitor the WUS for a time shorter than Wmax. The UE may assume the shorter time has a dependency on variables associated with the base station and WUS. The base station may indicate this dependency to the UE either implicitly or explicitly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for identifying narrowband reference signal (NRS) tones that are to be received in association with a scheduled paging occasion, wherein the NRS tones are configured to be received via a non-anchor carrier regardless of whether a page is to be received in connection with the scheduled paging occasion; and receive the NRS tones via the non-anchor carrier based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

Abstract: Some techniques and apparatuses described herein provide synchronization signal numerology, coverage extension/repetition schemes, and synchronization signal burst set periodicities for 5G IoT user equipment (UEs). For example, some techniques and apparatuses described herein provide a sequence of slots and/or particular symbols within a slot for transmission of a synchronization signal and/or a broadcast channel. Furthermore, some techniques and apparatuses described herein define minimum bandwidths of IoT UEs in relation to non-IoT UEs, and define synchronization signal burst set periodicities that may be different for IoT UEs than for non-IoT UEs.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.

Abstract: Aspects described herein relate to communicating with one or more cells for receiving a multicast and/or broadcast service (MBS), and providing MBS continuity in device mobility scenarios. In an aspect, one or more cells for reselection from a current cell can be detected, where the current cell supports a UE interested MBS. The one or more cells can be evaluated for reselection based at least in part on whether the one or more cells support the UE interested MBS to determine a target cell for reselection. Cell reselection can be performed to the target cell.
