摘要： Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for designing quality report for enhanced Machine Type Communication (EMTC) and Narrowband Internet of Things (NB-IOT). For example, some embodiments are directed to a user equipment (UE) including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to determine a downlink (DL) quality metric based on a DL quality metric type and identify a message 3 (Msg3) signal based on the determined DL quality metric. The processor circuitry can further be configured to transmit, using the radio front end circuitry, the identified Msg3 signal to a base station.

摘要： Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for the reduction of handover interruptions. Some embodiments include a user equipment (UE) that supports simultaneous connectivity with a source 5G Node B (gNB) and a target gNB during a handover. Some embodiments include the UE receiving source path data packets from the source gNB and target path data packets from a target gNB. The UE performs a first reorder of the one or more source path data packets and the one or more target path data packets by sequence number (SN), and the UE performs header decompression on the reordered source path data packets, separately from the reordered target path data packets. After the header decompressions the UE performs a second reorder of the source path data packets and the target path data packets together by SN, and discards any duplicate data packets based on SNs.

摘要： A telecommunication network may operate to enable a wake up signals (WUSs) within the telecommunication network. A mobility management entity (MME) may estimate a coverage enhancement (CE) level of a user equipment (UE), determine, based on the CE level, a number of repetitions for a wake up signal (WUS) for the UE, and cause a WUS for UE to be transmitted to a radio access network (RAN) node corresponding to the UE. The RAN node may inform the MME that the RAN node has disabled the WUS feature, and may cause system information to be broadcast to UEs in IDLE mode, indicating that the WUS feature of the RAN node has been disabled. A UE may determine a paging occasion (PO) determine a maximum WUS duration, minimum offset, and start location of the WUS.

摘要： Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

摘要： Technology is disclosed for an evolved node B (eNB) operable for early data transmission (EDT) in a user plane (UP) in a cellular internet of things (CIoT) evolved 5 packet system (EPS) network. The eNB can be configured to encode, at the eNB for transmission to a user equipment (UE), a message 4 (Msg4) including a resume identifier (ID) and a next-hop chaining count (NCC). The eNB can be configured to determine, at the eNB, a delivery status of the Msg4 to the UE. The eNB can be configured to encode, at the eNB for transmission to a previous eNB of the UE, one or more of an EDT failure 10 indicator or the resume ID.

摘要： Systems, devices, and techniques for handover and false base station detection in a wireless communication network are described. A described technique performed by a user equipment (UE) includes receiving, from a source base station of a wireless network, a handover command to indicate a handover to a target base station for communication in the wireless network; receiving information from the target base station; determining whether the target base station is a legitimate base station of the wireless network based on the information from the target base station and handover information included in the handover command; and performing a handover based on the handover command and a determination that the target base station is the legitimate base station.

摘要： This disclosure describes methods, systems, and devices for uplink data integrity protection in a communication system including a radio access network (RAN) serving a user equipment (UE) operating in an Early Data Transmission (EDT) configuration. In one example, a method involves generating a hash marker based on a packet data convergence protocol (PDCP) control protocol data unit (PDU) or service data unit (SDU). The method also involves transmitting a message including the hash marker to the RAN.
