The base station may also transmit, via the plurality of resources, one or more PDSCHs based on the at least one parameter of the one or more parameters of the PDSCH group. The UE may receive the indication of at least one parameter of the PDSCH group including multiple PDSCHs for each beam in a plurality of beams, and receive, from the base station, one or more PDSCHs based on the indication.

Abstract: Systems and methods are provided for efficient handling of user requests to access shared resources in a distributed system, which handling may include throttling access to resources on a per-resource basis. A distributed load-balancing system can be logically represented as a hierarchical token bucket cache, where a global cache contains token buckets corresponding to individual resources whose tokens can be dispensed to service hosts each maintaining a local cache with token buckets that limit the servicing of requests to access those resources. Local and global caches can be implemented with a variant of a lazy token bucket algorithm to enable limiting the amount of communication required to manage cache state. High granularity of resource management can thus enable increased throttle limits on user accounts without risking overutilization of individual resources.

Abstract: Embodiments relate to a system, program product, and method for employing feature engineering to improve classifier performance. A first machine learning (ML) model with a first learning program is selected. The first selected ML model is operatively associated with a first structured dataset. First features in the first dataset directed at performance of the selected ML model are identified. A second structured dataset is assessed with respect to the identified features in the first dataset, and new features in the second dataset are identified, where the new features are semantically related to the identified features in the first dataset. The first dataset is dynamically augmented with the identified new features in the second dataset. The dynamically augmented first dataset is applied to the selected ML model to subject an embedded learning algorithm of the selected ML model to training using the augmented first dataset.

Abstract: A method performed by a source Radio Network Controller (RNC) for handling a relocation of a User Equipment (UE) connection from the source RNC to a target RNC to serve the UE in an ongoing wireless communication is provided. An interface between the source RNC and the target RNC is available. When all radio links in the ongoing wireless communication are controlled by the target RNC and a triggering condition is fulfilled for relocation of the UE connection from the source RNC to the target RNC, the source RNC decides (202) to discontinue to use said interface. Then a core network is used for sending (204) to the target RNC, a triggering of the relocation procedure for relocating the source RNC to the target RNC to serve the UE. A Radio Resource Control (RRC) configuration defined by the target RNC to be used after the relocation to the target RNC is then obtained (205) via the core network.

Abstract: Apparatuses, methods, and systems are disclosed for selecting a base unit in response to a handover condition being triggered. One method (1000) includes selecting (1002) a base unit of multiple base units for handover in response to at least one base unit of the multiple base units triggering a handover condition. The method (1000) includes transmitting (1004) a random access preamble to the base unit. The method (1000) includes performing (1006) a reestablishment procedure to establish communication with one base unit of the multiple base units in response to determining an inability to access each base unit of the multiple base units that meets the handover condition.

Abstract: A device allocates buffer space for storing data received from another device. The other device has a credit balance corresponding to the amount of buffer space. A sending device reduces its number of credits by a cost of a packet and sends the packet. To ensure that the buffer does not overflow, the sending device spends a credit for each entry in the buffer that could be consumed by the sent data packet. When received data is added to the buffer without consuming a new entry, a response packet that returns a credit is sent to the sending device before the data is read from the buffer. Thus, the sending device is enabled to continue sending data without waiting for the buffer to be read, enabling the communication between the two devices to make more efficient use of the buffer.

Abstract: The present technology is directed to routing a user equipment (UE) to a network node, for example, a gNB or ng-eNB that supports a slice requirement of the UE. A first network node can receive a Radio Resource Control (RCC) connection request from a UE, and can determine that a slice requirement of the UE is not supported by the first network node. The first network node can further select a second network node that supports the slice requirement of the UE, and route the UE to connect to the second network node.

Abstract: Disclosed is a system for tracking and dynamically allocating wireless capacity within a wireless telecommunications network. The system has a plurality of processor levels: a layer of baseband-level capacity processors that are deployed within each baseband processor; a layer of client-level capacity processors that are deployed within each wireless base station; a layer of server-level capacity processors, each of which orchestrate allocation of wireless capacity over a unique domain of wireless base stations; and a master level capacity processor. Wireless capacity is allocated in terms of active connections to wireless devices, and the active connections are quantized and allocated as logical connections, or connection tokens. The system dynamically allocates wireless capacity so that resources are devoted to venues and environments where demand is greatest at any given time.

Abstract: Aspects relate to wireless communication on multiple component carriers. In some examples, a user equipment (UE) may selectively apply transmission configuration indicator (TCI) information and/or spatial relation information received via a medium access control—control element (MAC-CE) to component carriers. In some examples, a UE may apply the TCI information and/or spatial relation information included in a MAC-CE to multiple component carriers if the UE has been configured with a list that includes the component carriers (and, optionally, if a component carrier identified by the MAC-CE is a member of the list of component carriers). If the above condition is (or conditions are) not met, the UE applies the TCI information and/or spatial relation information included in the MAC-CE to the component carrier identified by the MAC-CE.

Abstract: The disclosure relates to a method and apparatus for reporting a radio link failure (RLF) in a mobile communication system. According to an embodiment of the disclosure, a method, performed by a user equipment, of reporting an RLF includes detecting a first RLF during use of a first radio access technology (RAT), accessing a base station by using a second RAT different from the first RAT, and transmitting a report on the first RLF to the base station by using the second RAT.

Abstract: Provided are a data transmission method and apparatus and a computer storage medium. The method may include: a source Distributed Unit (DU) reports a packet data convergence protocol (PDCP) transmission state report to a source Centralized Unit (CU), where the PDCP transmission state report enables the CU to determine which PDCP protocol data unit (PDU) data is not successfully received by a UE; and the PDCP PDU data which is not successfully received by the UE are retransmitted to the UE via a target DU.

Abstract: Indication of transmission priority class is disclosed for sharing a base station's maximum channel occupancy time (MCOT) for use in autonomous uplink (AUL). Aspects of the disclosure provide for implicitly sharing the MCOT by providing an indication of transmission opportunity (TxOP) length. A serving base station sends an indication of a current TxOP length in control signals to a user equipment (UE). The UE may then infer a set of potential transmission priorities used by the serving base station according to the TxOP length, as TxOP length may relate to the MCOT, which itself may be associated with a particular transmission priority class. The UE may then, conservatively, select the highest transmission priority of the set of potential transmission priorities for autonomously transmitting any uplink data having at least the selected highest transmission priority within configured AUL resource of the current TxOP.
