  • Patent number: 10813075
    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.

  • Patent number: 10813086
    Abstract: A wireless local area network (WLAN) point-to-point communications link between an evolved universal terrestrial radio access network node B (eNB) and a user equipment device (or simply UE) is identified by UE/eNB media access control (MAC) identifiers on a per UE or per data radio bearer (DRB) basis for offloading cellular data from a long term evolution (LTE) link to the WLAN point-to-point communications link. A wireless local area network tunneling protocol (WLTP) includes packet formats and network protocol stack arrangements to support functions facilitated by the WLAN point-to-point communications link, such as, for example, identification of control and data traffic messages, DRB identification for WLTP packets, quality of service (QoS) delay and packet loss measurement, support of bearer splitting, and support of a general framework for offloading cellular traffic at different depths of the 3rd Generation Partnership Project (3GPP) network protocol stack.

  • Publication number: 20200322756
    Abstract: Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.
