  • Patent number: 11134361
    Abstract: A Location Management Component (LMC) may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU receives location related messages from any of (i) a UE via a gNB Distributed Units (gNB-DU), (ii) another gNB via an Xn interface, or (iii) a core network entity (e.g. AMF) via an NG interface. These messages can be transported in container messages (e.g., an RRC container for LPP messages sent to or received from a UE; an NGAP container for messages sent to or received from an AMF, or an XnAP container for messages sent to or received from another gNB). The gNB-CU removes the location related messages from the container messages and forwards them to an LMC using F1-AP container messages. Location related messages sent from an LMC to other entities are transported in a reverse manner through a gNB-CU using corresponding container messages.

  • Publication number: 20210259031
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may truncate or remove a number of bits from its UE identity based on identity truncating information to generate a truncated UE identity. The truncated UE identity can be transmitted by eMTC devices to a base station in an RRC connection request, and can be used by the base station to determine which core network entity stores the UE's capabilities. In some implementations, the UE may truncate or remove a number of bits from the 48-bit 5G-S-TMSI based on the identity truncating information to generate a 40-bit truncated 5G-S-TMSI that can be transmitted by an eMTC device to the base station in the RRC connection request and yet still provide the base station with enough information to determine which AMF stores the UE context.

  • Publication number: 20210250825
    Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.
