Overcoming Neighbor Relation Table Conflicts Among Terrestrial and Aerial Cells in Mobile Telecommunications Networks
An enhanced automatic neighbor relation (“ANR”) function can estimate a plurality of terrestrial cells within a coverage area of an aerial cell. The enhanced ANR function can monitor an exchange of a serving cell unique identifier sent to a target cell and a target cell unique identifier associated sent to a serving cell. The enhanced ANR function can determine a serving cell type and a target cell type, wherein the serving cell type and the target cell type identify the serving cell and the target cell, respectively, as either a terrestrial cell type or an aerial cell type. The enhanced ANR function can then determine whether a serving cell neighbor relation table (“NRT”) associated with the serving cell, a target cell NRT associated with the target cell, or both would be compromised if a corresponding NR is added into the serving cell NRT and the target cell NRT.

Cell handover method and device
A cell handover method and a device are provided, so that a target eNB uses a current serving small node as a user plane serving node after a UE is handed over. The UE and uses the target eNB as a control plane serving node after the handover. The method includes receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. According to the application, a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great is avoided, because the current serving small node forwards a large amount of data to the target eNB.

Mobility-aware access control
Certain aspects of the present disclosure provide techniques for mobility-aware access control. A method that may be performed by a first wireless device generally includes receiving one or more signals from a second wireless device in the network, wherein the one or more signals provide an indication of a mobility state corresponding to the second wireless device; determining whether to establish a connection with the second wireless device based, at least in part, on the indication of the mobility state corresponding to the second wireless device; and taking one or more actions based on the determination. Other aspects, embodiments, and features are also claimed and described.

Method of performing cell selection or reselection and related device
A method of performing cell selection or reselection by a user equipment (UE) in a radio resource control (RRC) idle mode or an RRC inactive mode is disclosed. The method comprises determining whether a white list is received from a serving cell, wherein the white list includes at least one cell identity, each of the at least one cell identity identifying a cell on at least one of an intra-frequency and an inter-frequency corresponding to a frequency that the serving cell is on, in response to the UE determining that the white list is received from the serving cell, performing a measurement on at least one cell associated with the at least one cell identity according to the white list, and selecting or reselecting a cell according to the measurement, the cell indicated only by the at least one cell identity in the white list.

SYSTEMS AND METHODS FOR UE OPERATION IN PRESENCE OF CCA
Systems and methods for User Equipment (UE) operation in presence of Clear Channel Assessment (CCA) are provided. In some embodiments, a method performed by a wireless device for cell selection accounting for requirements includes: determining a measurement period in a serving cell for the cell selection or cell re-selection (T1), wherein the measurement period is determined based on a number of consecutive Discontinuous Reception (DRX) cycles; determining a number of measurement occasions configured with a Discovery Reference Signal (DRS) in the serving cell during T1; determining availability of the DRS at the measurement occasions; and performing measurement based on availability of the DRS at the measurement occasions during T1. In this way, a wireless device may operate in NR RRC_IDLE/RRC_INACTIVE in the presence of CCA, e.g., Listen-Before-Talk (LBT).
Directing client devices between co-located macro and micro wireless cells
Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.
