Patent number: 11627636Abstract: A wireless communication network exchanges data communication over Session Communication Proxies (SCPs). In the wireless network, the SCPs determine and transfer location information and status data to a Network Repository Function (NRF). The NRF receives the location information and status data and prioritizes the SCPs based on the location information and the status data. A requesting Network Function (NF) transfers an NF request to the NRF. The NRF receives the NF request from the requesting NF. In response, the NRF generates and transfers a list that prioritizes the SCPs based on the location information and the status data to the requesting NF. The requesting NF selects one of the SCPs based on the location information and the status data and transfers NF data to the selected one of the SCPs. The selected one of the SCPs forwards the NF data to a target NF.Type: GrantFiled: April 23, 2021Date of Patent: April 11, 2023Assignee: T-MOBILE INNOVATIONS LLCInventor: Rajil Malhotra

Patent number: 11589417Abstract: Systems and methods are described for indicating a range for which HARQ feedback is to be transmitted for sidelink V2X communications. A TX UE receives from a gNB an RRC message with an IE that describes a communication range. The communication range is used by a RX UE when the TX UE transmits a groupcast PSSCH and PSCCH to the RX UE to determine whether or not to send HARQ feedback in response to the TX UE transmission. The RX UE receives the communication range from the gNB or the TX UE signals the communication range in the SCI of the PSCCH. If the TX UE sends a TB in which multiple DRBs with different communication ranges are used for the PDU, the SCI indicates that either the maximum or minimum communication range is to be used.Type: GrantFiled: June 23, 2020Date of Patent: February 21, 2023Assignee: Intel CorporationInventor: Honglei Miao
