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.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for maximizing the potential of resources dedicated to aerial user equipment (UEs). In one example, a UE may receive signaling indicating that a cell supports communications exclusively with aerial UEs. The signaling may be used to bar non-aerial UEs from accessing the cell and reserve resources for communications with aerial UEs. In another example, a UE may receive signaling identifying one or more frequency bands dedicated to aerial UEs. The UE may then communicate on the one or more frequency bands. In yet another example, a UE may receive signaling indicating a set of aerial access categories supported by a cell. The signaling may be used to reserve resources for high-priority aerial UEs (e.g., aerial UEs used for law enforcement purposes).

Abstract: Methods, systems, and devices for wireless communications are described in which random access preambles may be designed to provide for relatively low inter-carrier interference (ICI) of adjacent available frequency resources in a non-terrestrial network (NTN). Random access preambles for NTN random access requests may be selected from a first set of random access preambles that are different from a second set of random access preambles for terrestrial random access requests. The first set of random access preambles may be a subset of the second set of random access preambles. The first set of random access preambles may be provided for contention-based random access (CBRA) and contention-free random access (CFRA) preambles may be configured by a base station from random access preambles that correspond to or are different from the second set of random access preambles.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for measuring, filtering, and reporting cross-link interference (CLI) in cases where not all aggressor user equipments (UEs) are transmitting signals that can be measured by a victim UE. A UE may obtain a set of CLI measurements by performing CLI measurements during a set of CLI measurement occasions. The UE may determine a first subset of the set of CLI measurements that satisfy a CLI measurement threshold and a second subset of the set of CLI measurements that do not satisfy the CLI measurement threshold. The UE may apply a filter to the first subset of the set of CLI measurements, and suppress the filter for the second subset of the set of CLI measurements, to obtain a filtered CLI measurement value. The UE may transmit the filtered CLI measurement value to a base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information indicating whether measurement is permitted on a non-anchor carrier; and selectively perform a measurement on at least one of the non-anchor carrier or an anchor carrier, based at least in part on the information indicating whether the measurement is permitted on the non-anchor carrier. Numerous other aspects are provided.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting user equipment (UE)-shared multicast feedback. In some systems, a UE and a base station may support multicast communications. The base station may configure a set of physical uplink control channel (PUCCH) resources that the UE may use for multicast feedback messages. The base station may transmit an indication of the set of PUCCH resources to the UE, and the UE may determine to use a PUCCH resource of the set of PUCCH resources based on one or more indications from the base station. The UE may fail to receive a multicast message from the base station and may transmit a UE-shared negative acknowledgment (NACK) feedback message. The base station may re-transmit the multicast message according to a set of transmission parameters that is based on which PUCCH resource was used by one or more UEs for multicast NACK feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.
