Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine information indicating an association between the UE and a preconfigured uplink resource (PUR). The UE may transmit a message including the information indicating the association between the UE and the PUR. A base station may receive the message including the information indicating the association between the UE and the PUR. The base station may identify the UE associated with the PUR based at least in part on the information indicating the association between the UE and the PUR. Numerous other aspects are provided.

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: Disclosed embodiments facilitate UE location determination in systems with dense PRS configurations, reduced PRS periodicity, frequency hopping, and involving UE inter-frequency measurements. The techniques may be applied to Bandwidth reduced-Low complexity (BL) UEs, or enhanced Machine Type Communication (eMTC) UEs or Further enhanced MTC (FeMTC) UEs and/or in LTE-M systems. A method on a UE may comprise: receiving a Reference Signal Time Difference (RSTD) measurement request; transmitting, in response to the RSTD measurement request, a dedicated gap request comprising a requested configuration of dedicated gaps; and receiving, in response to the dedicated gap request, a message comprising a dedicated gap configuration. The dedicated gap request may comprise a request for dedicated measurement gaps and the message may comprise a dedicated measurement gap configuration. In some embodiments, the dedicated gap request may comprise a request for dedicated autonomous gaps and the message may comprise a dedicated autonomous gap configuration.

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: A wakeup signal (WUS) group that may be divided into WUS sub-groups, criteria or metrics for dividing the WUS group into a set of WUS sub-groups, and signaling or messaging to support the division of the WUS group into the set of WUS sub-groups are provided. For example, a set of UEs may be divided into WUS sub-groups based at least in part on respective frequencies of occurrence of paging occasions for the set of UEs (e.g., based at least in part on traffic type, observations regarding past paging occasions, predictions regarding future paging occasions, and/or the like) and/or based at least in part on other considerations. Furthermore, some techniques and apparatuses described herein provide for the mapping of network device-level WUS sub-groups (e.g., supported by a network device such as an MME) to base station-level WUS sub-groups (e.g., supported by a base station).

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to adjusting how certain types of devices wake up and/or stay awake for broadcast service. A method for wireless communications is provided that may be performed by a user equipment (UE). The method includes receiving a power savings configuration indicating sleep periods during which the UE is scheduled to be unreachable. The method includes determining at least one time, during at least a portion of one of the indicated sleep periods, for the UE to be awake in order to at least one of: receive or discover Multimedia Broadcast Multicast Services (MBMS) user services.

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.
