Abstract: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.

Abstract: One or more methods of using simultaneous connectivity and conditional handover together. At least one of the methods includes transmitting, by a target base station, a reserved resource release command to a source; transmitting, by the source, a new handover (HO) command to update a list of conditional HO (CHO) candidate cells; and releasing, by the target base station, a reserved resource for the UE.

Abstract: 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.

Abstract: The techniques, described herein, may enable a wireless telecommunication network to manage Mobility Management Entity (MME) overload scenarios by causing a Radio Access Network (RAN) node to temporarily bar certain User Equipment (UEs) from connecting to the RAN node. In some embodiments, UEs may be barred from connecting to the RAN node based on which UEs are operating in an enhanced coverage mode, Coverage Enhancement (CE) levels of each UE, and/or a measured Reference Signal Received Power (RSRP) of each UE.

Abstract: Provided herein is design of early data transmission in wireless communication system. An apparatus for a user equipment (UE) includes a processor configured to: encode a physical random access channel (PRACH) sequence from a plurality of PRACH sequence for transmission via a PRACH to perform a random access procedure, wherein indication of support of early data transmission (EDT) that is transmitted during the random access procedure is based on at least one of the plurality of PRACH sequences, higher layer signaling, PRACH resources, PRACH formats, and a payload from the UE; and send the PRACH sequence to a radio frequency (RF) interface; and the RF interface to receive the PRACH sequence from the processor. Design of random access response (RAR) is also disclosed herein.

Abstract: An approach is described for a user equipment (UE) for enhanced machine-type communication (eMTC) in a connected mode, where the UE includes processor circuitry and radio front end circuitry. The processor circuitry is configured to perform a downlink (DL) quality measurement, and to generate a DL quality report based on the DL quality measurement, wherein a definition of the DL quality report matches a definition of quality report in Msg3. The radio front end circuitry is configured to transmit the DL quality report to a next generation base station (gNB).

Abstract: Technology for an Integrated Access and Backhaul (IAB) node in an IAB network is disclosed. The IAB node can decode, at a distributed unit (DU) of the IAB node, a first resource request received from one of a user equipment (UE) or a child IAB node, wherein the first resource request is associated with the UE. The IAB node can encode, at a mobile terminal (MT) of the IAB node, a second resource request for transmission to the parent IAB node or the IAB donor triggered by receipt of the first resource request, wherein the second resource request is transmitted prior to a receipt of a protocol data unit (PDU) at the DU of the IAB node.

Abstract: 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.
