Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, informing and/or requesting the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: The exemplary embodiments relate to a user equipment (UE) delivering an indication of one or more uplink listen-before-talk (LBT) failures to a network. The UE may identify a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell). The UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition. Next, the UE may determine a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network. The UE may transmit the type of message including the indication of uplink LBT failure associated with the SpCell to the network. Subsequently, the UE may determine that the network received the indication of uplink LBT failure associated with the SpCell.

Abstract: Systems and methods are provided for public land mobile network (PLMN) selection for disaster roaming. A user equipment (UE) determines a disaster condition at a first PLMN, where the UE is a subscriber of the first PLMN. The UE determines an availability of a second PLMN for disaster roaming. The UE selects the second PLMN and attempts registration on the second PLMN for disaster roaming. In response to attempting the registration on the second PLMN for disaster roaming, the UE receives a registration reject message including a cause value corresponding to a registration failure for disaster roaming on the second PLMN due to the disaster condition on the first PLMN. The UE waits for a first period of time before again attempting to register for disaster roaming on the second PLMN for the first PLMN with the disaster condition.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: generating a registration request comprising a capability of the UE to serve as a gateway for a personal Internet-of-things network (PIN); sending the registration request to a base station serving the UE; receiving, from the base station, a registration accept message comprising a PIN gateway authorization; and initiating establishment of the PIN with at least one other device, wherein the UE serves as the gateway of the PIN to the base station.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).

Abstract: Some aspects include an apparatus, method, and computer program product for facilitating control messaging for multi-beam communications in 5G wireless communication systems. Nodes of a 5G network may be generate Medium Access Control Control Elements (MAC CEs) to update User Equipment (UE) with different Component Carrier (CC) settings. The MAC CEs may update a list of CCs to reduce messaging overhead and latency. For example, a MAC CE may indicate an update for a Transmission Configuration Indication (TCI) state for a list of CCs. Similarly, a MAC CE may be used to update a spatial relation for a Sounding Reference Signal (SRS) resource set and/or a SRS resource corresponding to a list of CCs. A MAC CE may also be used to update multiple TCI codepoints having one or two TCI states in a multi-Transmission Reception Point (multi-TRP) scenario.

Abstract: Techniques, described herein, include solutions for enabling a user equipment (UEs) to operate in a power saving mode (PSM) by performing radio link monitoring (RLM), beam failure detection (BFD), and radio resource management (RRM) based on one or more reference signals with a decreased periodicity. The reference signals may include system synchronizations blocks (SSBs), a channel state information (CSI) m signal (CSI-RSs), or a combination thereof. A base station may be configured to operate as a master cell group (MCG) node or a secondary cell group (SCG) node and may transmit reference signals with an increased periodicity to UEs in an active mode of operation while also transmitting reference signals with a decreased periodicity to UEs in a PSM.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.
