Abstract:
Methods and apparatuses for communicating in a wireless network include receiving full and differential System Information Blocks (SIBs) and updating a parameter that has changed based on the differential SIB. Further apparatuses include control circuitry to generate a first SIB and second SIB, the second SIB indicating information that has changed. Further, a method includes generating a full SIB and generating a differential SIB based on updated parameters.
Abstract:
Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.
Abstract:
Systems and methods disclosed herein provide in-device co-existence interference avoidance for a wireless communication device in dual connectivity with a master node and a secondary node. Time-division multiplexing (TDM) assistance information sent by the wireless communication device is forwarded from the master node to the secondary node. The master node and/or the secondary node uses the TDM assistance information to determine a TDM solution for the in-device co-existence interference in the wireless communication device.
Abstract:
Technology for efficiently splitting a bearer at the packet data convergence protocol (PDCP) layer for uplink (UL) data transfers in wireless networks where dual connectivity is available is disclosed. A user equipment (UE) can send buffer status reports (BSRs) to a master evolved node B (MeNB) and a secondary evolved node B (SeNB). The BSRs can be formatted such that the amount of data in a radio link control (RLC) buffer at the UE and the amount of data in a packet data convergence protocol (PDCP) buffer at the UE are contained in different fields. The BSRs can also contain redundancy indicator (RI) values specifying a redundancy level between the PDCP buffer amounts included in the BSRS. The MeNB and the SeNB may then coordinate, via an X2 interface, an amount of uplink (UL) resources to allocate to the UE.
Abstract:
The present disclosure is related to connected vehicles, computer-assisted and/or autonomous driving vehicles, Internet of Vehicles (IoV), Intelligent Transportation Systems (ITS), and Vehicle-to-Everything (V2X) technologies, and in particular, to enhanced decentralized environment notification (DEN) services and safety metrics based pre-crash warning for DEN messages (DENMs). The enhanced DEN services include mechanisms to alert road users of detected dangerous events due to safety metric violations, which are calculated based on sensor data/measurements. Safety metric-specific attributes are included in the DENM á la-carte container to carry the safety metrics violation to the neighboring stations. Additionally, the DENM situation container is also enhanced/expanded such that event type values can incorporate the safety metric violations and/or related events. For each metric, there is a threshold for triggering a DENM warning message, and the triggering conditions and logic for message generation are also described.
Abstract:
In embodiments, apparatuses, methods, and storage media may be described for monitoring channel quality of a radio link between a secondary evolved NodeB (SeNB) and a user equipment (UE) in a wireless communication network configured for dual connectivity. In embodiments, the UE may generate one or more indications of a channel quality of the SeNB-UE radio link and forward the indication to the SeNB. Based on the indication, the UE may receive a radio resource control (RRC) message from a master eNB (MeNB) related to the SeNB-UE radio link. Other embodiments may be claimed.
Abstract:
In accordance with some embodiments, a user equipment or mobile station may provide assistance to the eNB or base station so that eNB or base station can more effectively provide settings to the user equipment. Because the user equipment may have more in depth knowledge about the conditions that exist at the user equipment, efficiencies may be achieved by providing information to the eNB from which the eNB can better set various settings on the user equipment, including those related to power saving and latency.
Abstract:
Methods and apparatus for communicating in a wireless network include mechanisms to facilitate concurrent use of periodic scheduling requests and a random access procedure for a UE to request uplink resources from an eNB.
Abstract:
Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connectivity mode on respective wireless cells provided by first and second eNBs. The UE may communicate with a first eNB in a first frequency band. The UE may communicate with a second eNB in a second frequency band. The first eNB may detect that the second frequency band is unavailable. Based on this detection, the first eNB may notify the UE that communication in the second frequency band is no longer available. In response, the UE may control a radio to cease communication in the second frequency band. Other embodiments may be described and/or claimed.
Abstract:
Embodiments of the present disclosure describe systems and methods for operation of an evolved node B to provide multiple coverage enhancement levels. Various embodiments may include an operational mode configured to provide a first coverage enhancement level associated with user equipments (UEs) that have established communication with the eNB. These embodiments may also include a discovery mode configured to operate at a second coverage enhancement level to discover UEs configured for a higher coverage enhancement level. Other embodiments may be described and/or claimed.
