Abstract: Some techniques and apparatuses described herein allocate and/or transmit a narrower bandwidth value for LTE MTC UEs, such as UEs that operate in a small bandwidth mode using LTE procedures, and allocate and/or transmit a wider bandwidth value for 5G MTC UEs, such as UEs that can perform hopping and/or be allocated resources outside of a legacy bandwidth. For example, the wider bandwidth value may be associated with a non-LTE carrier (e.g., a 5G carrier in a 5G bandwidth) with the same center frequency as an LTE carrier associated with the narrower bandwidth value. Some techniques and apparatuses described herein provide for initial access, signaling, paging, random access, unicast communications, frequency hopping, cell-specific reference signaling, narrowband alignment, and/or other coexistence considerations for LTE MTC UEs operating on an LTE carrier and 5G MTC UEs operating on a non-LTE carrier with a bandwidth that includes the LTE carrier.

Abstract: Aspects are provided which allow coverage enhancement and support in NTNs for repetition, frequency hopping, and antenna switching during msgA transmissions based on a preamble-to-PO mapping. In one aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with at least one PO for two-step random access, where the PO spans a time interval greater than one slot. In another aspect, the base station provides and the UE obtains a RACH configuration associating a preamble with a plurality of POs for two-step random access. In a further aspect, the base station provides the UE a plurality of configurations each indicating a PO for two-step random access. In an additional aspect, the base station provides the UE a configuration indicating a guard band for a PO for two-step random access, where the guard band is indicated in units of subcarriers spanning less than one PRB.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may communicate with a user equipment (UE) or multiple UEs using multicast transmissions, and each of the multiple UEs may use shared resources to transmit feedback. A UE may receive a power control configuration associated with multicast communications and indicating one or more control parameters or weighting factors for uplink feedback. The UE may monitor a set of downlink resources for the multicast message from the base station, and may determine a decoding failure for the multicast message. The UE may determine whether to transmit uplink feedback to the base station based on the received power control parameters, such as adjusting UE transmit power using a weighting factor or other power control parameters. The UE may determine whether to transmit the uplink feedback message indicating the decoding failure based on the power control configuration.

Abstract: In an embodiment, a drone-coupled UE transmits a message to a network component (e.g., eNB) of a terrestrial wireless communication subscriber network that identifies a drone-coupled capability information of the drone-coupled UE, the drone-coupled capability information being configured to indicate, to the network component, that the drone-coupled UE is capable of engaging in a flying state. The network component receives the message and determines that the drone-coupled UE is capable of engaging in a flying state based on the received message.

Abstract: Methods, systems, and devices for wireless device are described. A wireless device may receive a configuration for a data radio bearer associated with voice traffic in a wireless communications network. In some examples, the configuration may indicate one or more parameters associated with the voice traffic. Additionally, or alternatively, the wireless device may receive a configuration for a data radio bearer and a configured grant associated with voice traffic. The wireless device may identify a mapping between a configured grant identifier and the data radio bearer based on the configuration In some examples, the wireless device may generate a transport block including the voice traffic based on the one or more parameters associated with the voice traffic or the mapping between the configured grant identifier and the data radio bearer. The wireless device may then transmit the generated transport block including the voice traffic.

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. 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.

Abstract: Improvements are provided to the paging process for an eMTC UE by allowing a base station and the UE to apply a UE-specific DRX cycle for paging, from one set of DRX cycles, when the UE is operating in non-CE mode and apply another UE-specific DRX cycle, from a more restricted set of UE-specific DRX cycles, when the UE is operating in a CE mode. A UE may report and apply certain UE-specific DRX cycles under non-CE mode, and may change a UE-specific DRX cycle to one from a more restricted set when operating in CE mode. Similarly, base stations may receive the reported UE-specific DRX cycle and apply that UE-specific DRX cycle for paging the UE in non-CE mode, while applying a different UE-specific DRX cycle from the more restrictive set for paging the UE in CE mode.

Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.
