Patent number: 11963248Abstract: A computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for small data transmission (SDT) in a 5G NR network and cause the UE to perform operations comprising detecting while in an RRC_Inactive state, a radio link failure during a first SDT of UL data to a base station. A secure key for a second SDT is generated based on the radio link failure. A configuration message including an indication of the second SDT is transmitted to the base station. A response message including a UL grant is received from the base station. The UL data is encoded for the second SDT using the secure key. The second SDT is performed using the UL grant while the UE is in the RRC_Inactive state.Type: GrantFiled: October 18, 2021Date of Patent: April 16, 2024Assignee: Intel CorporationInventors: Sudeep K.

Patent number: 11963036Abstract: An apparatus and system to enable dynamic offloading and execution of compute tasks are described. In split CU-DU RAN architectures, the CU-CP is connected with multiple compute control functions (CF) and service functions (SF) that have different computing hardware/software capabilities. Different architectures depend on whether the SF is collocated with the CU-UP, the CU-UP and SF only serve compute messages, a compute message is supplied directly to the CU-UP or also traverses the CU-CP. In response to reception from a UE of a compute message containing data for computation being sent to the CU-CP through the DU, the CU-CP sends the data to the SF with identifiers and sends the result to the UE.Type: GrantFiled: August 18, 2021Date of Patent: April 16, 2024Assignee: Intel CorporationInventors: Sangeetha L.

Publication number: 20240048967Abstract: Systems and methods of providing UE capability are described. A capability ID is associated with the same Radio Capability information for multiple UEs. If the capability ID is validated at a network node, the UE provides the capability ID to a RAN node, which obtains the capability information from the network node after providing the received capability ID to the RAN node. The capability ID is received in an RRC Setup Complete. Security Mode Complete or Reconfiguration Complete message. The network node, if the Radio Capability information is not available, requests and receives the Radio Capability information and associates it with the capability ID, and marks that the capability ID as not validated until a threshold number of the UEs have provided the same Radio Capability information. The capability ID is based on a UE device type, manufacturer and software version.Type: ApplicationFiled: September 14, 2023Publication date: February 8, 2024Inventors: Sudeep K.

Publication number: 20240015698Abstract: Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PD SCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.Type: ApplicationFiled: September 22, 2023Publication date: January 11, 2024Inventors: Anthony LEE, Seau S.
