Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

Abstract: A user equipment (UE) is configured to deactivate/activate a point-to-multipoint (PTM) link of a multicast radio bearer (MRB). The UE receives, from a base station of a wireless network, a multicast radio bearer (MRB) configuration, wherein the MRB includes configuration of a split MRB including a point to multipoint (PTM) link and a point to point (PTP) link, deactivates or activates the PTM link based on the MRB configuration, reestablishes a radio link control (RLC) associated with the PTM link and recovers a packet data convergence protocol (PDCP).

Abstract: Systems, methods, and circuitries are provided for supporting blind retransmission. In one example, a method includes processing control information that indicates resources for communication of a physical downlink shared channel or a physical uplink shared channel (PDSCH/PUSCH) transmission and timing information for a retransmission of the PDSCH/PUSCH. The method includes configuring operation to: receive the PDSCH/PUSCH transmission based on the resources; and determine that a subsequent PDSCH/PUSCH received at a subsequent time corresponds to the retransmission of the PDSCH/PUSCH when the subsequent time coincides with the indicated timing information for the retransmission and, in response combine the PDSCH/PUSCH with the retransmission in a HARQ buffer for decoding purposes.

Abstract: A user equipment (UE) may establish a connection with a network for transmission of a plurality of data bursts further comprising a plurality of data segments. The UE may transmit, to the network, a first data segment corresponding to a first quality of service flow identifier (QFI) associated with a first quality of service (QoS) flow and a second data segment corresponding to a second QFI associated with a second QoS flow. The UE may be configured to map one or more data segments to one or more QFIs based on at least one of a slice type, a frame type, a modulo operation, and a sequence number. The plurality of data bursts may be transmitted according to at least one of one or more configured grants (CGs), one or more dynamic grants (DGs), and one or more instances of the one or more CGs or one or more DGs.

Abstract: This disclosure relates to techniques for performing paging forwarding for remote wireless devices in a wireless communication system. A relay wireless device and a remote wireless device may establish a relay link. The relay wireless device may provide an indication of the relay link between the relay wireless device and the remote wireless device to a cellular base station. The relay wireless device may receive paging information for the remote wireless device from the cellular base station. The relay wireless device may provide the paging information to the remote wireless device via the relay link between the relay wireless device and the remote wireless device.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for L2 resets. For example, a UE can be connected to a base station DU via a first cell and can be configured with information about a second cell. This information can indicate whether an LTM association exists between the first cell and the second cell (e.g., whether these two cells are provided by the same base station DU or not). Upon a command to establish a connection with the second cell (e.g., a MAC CE handover command), the UE can determine whether an L2 reset is to be performed or not based on the configuration information (e.g., the L2 reset can be foregone when the two cells are provided by the same base station DU; otherwise, the L2 reset can be performed).

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: The present application relates to improved methods of application instance registration in a Multi-access Edge Computing (MEC) system, comprising, e.g.: receiving, at a MEC platform device, a registration request for a first application instance; determining, by the MEC platform device, that the first application instance is not presently registered; in response to determining that the first application instance is not presently registered, allocating, by the MEC platform device, a first application instance registration identifier for the first application instance; transmitting, by the MEC platform device, the first application instance registration identifier to the first application instance; and causing, by the MEC platform device, a first application instance registration notification to be sent to a MEC system-level management device. According to some aspects, the MEC platform device may first send a permission request to a MEC system-level management device to request permission to be able to register the first application instance.

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: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving, from a network, configuration of a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource); and while in a radio resource control (RRC) INACTIVE state, without entering an RRC CONNECTED state, using a contention-free random access (CFRA) process to transmit uplink data to a base station using the dedicated PRACH/preamble resource.
