Abstract: A network configures and transmits paging information. The network transmits configuration information to a user equipment (UE) operating in the network, wherein the configuration information comprises a value N based on a minimum gap between reception of a paging downlink control information (DCI) by the UE and fully processing the paging DCI by the UE, configures a paging DCI to be transmitted to the UE on a Physical Downlink Control Channel (PDCCH), wherein the paging DCI includes scheduling information for a Physical Downlink Shared Channel (PDSCH) and transmits the paging DCI to the UE on the PDCCH.

Abstract: A system for determining and reporting user equipment (UE) time gap requirement information for performing a measurement on a reference signal provided by a target base station. A UE receives a radio resource control (RRC) message from a current base station to modify a current RRC connection. The RRC configuration message may comprise sub carrier spacing (SCS) information of one or more target frequency bands of at least one target base station. The UE may then determine gap information based at least in part on the received SCS information of the one or more target frequency bands. The gap information may indicate whether a gap is needed in performing measurements on a reference signal transmitted at each of the one or more target frequency bands. The UE then transmits the gap information to the current base station.

Abstract: A method and apparatus for a wireless device of reduced capabilities to access a wireless communication network targeted to operate with wireless device having higher capabilities is disclosed. The device may receive from a base station of the wireless communication network an indication of whether the type of devices that includes the wireless device of reduced capabilities is allowed to access the wireless communication network. The device may transmit to the base station signaling associated with connecting to the base station if the base station indicates that the type of devices with reduced capabilities is allowed to access the wireless communication network. The signaling allows the device to connect to the base station. The device may transmit capability information of the device to the base station. The device may configure its features based on the capability information to communicate with the base station.

Abstract: One embodiment described herein takes the form of a user equipment (UE), such as a phone. The UE includes a transceiver and a processor. The processor is configured to establish a first radio resource control (RRC) connection with a base station via the transceiver. The processor is configured to associate with a secondary UE for collaboration of transmission of a data payload of one of the UE or the secondary UE to the base station, and transmit a first portion of the data payload to the base station via the transceiver.

IPC: H04L1/18

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

IPC: H04W72/04

Abstract: The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.

Abstract: Systems and methods for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality are disclosed herein. An IAB node includes a distributed unit (DU) having a local application instance of a MEC-enabled application. The local application instance is configured for communication with a first user equipment (UE) connected to the IAB node. A mobile termination functionality (MT) of the IAB node uses a packet data convergence protocol (PDCP) layer to transport data of the local application instance between the MT and an IAB donor. Further, data of the local application instance is transported between the UE and the IAB node via one of a variety of methods, including the use of a second PDCP layer at the DU (and optionally the use of service data adaptation protocol (SDAP) layers at each of the DU and the MT), and/or via sidelink.
