Abstract: Systems, methods, and apparatuses for user equipment (UE) autonomous radio resource configuration extension are provided. As disclosed herein, a UE may operate in dual connectivity with two (or more) base stations, each providing a set of carriers (e.g., cell groups) for wireless communication.

In some examples, the UE autonomously adjusts a measurement gap operation or adjusts a discontinuous reception (DRX) operation to account for a determined timing difference between carriers. The autonomous UE timing adjustments may include extending or offsetting a time duration or adjusting one or more subframes in which the operation is performed.

Abstract: The present technology pertains to unilaterally interleaving individual data packets of long bursts of multi-packet messages in various sequence patterns to be sent to one or more receivers over a network. Before determining a pattern, the sending device attempts to reduce the transmission length of the long bursts of the data packets into multiple chunks. Subsequently, the sending device generates a sequence pattern of the individual data packets and consecutively transmits these packets to their respective receivers. The determined sequence pattern may be based upon outbound limits at the sender, inbound limits at the one or more receivers, and various transmission priorities. Moreover, the sender may limit the data flow of any message transmission. The present technology does not require feedback from the network's components or from the network itself to micro flow control the individual data packets.

Abstract: Systems and methods are described for an automatically deployed wireless network. According to one embodiment, an access point controller (AC) determines the existence of a network anomaly at a position of a wireless network that is managed by the AC. Responsive thereto, the AC causes an unmanned vehicle that carries a movable access point (AP) to carry the movable AP to the position or proximate thereto and causes the movable AP to provide wireless network service to an area encompassing the position by sending a dispatch command to the unmanned vehicle. The dispatch command instructs the unmanned vehicle to move to the position or proximate thereto.

Abstract: A method and system to control WCD handover. A first base station will request load information from a second base station, and, based at least in part on a result of that request, the first base station will control handover of the WCD. The first base station may decline to hand over the WCD to the second base station in response to determining that the first base station did not responsively receive load information from the second base station. Further, the first base station may determine a level of confidence in load information of the second base station based on whether the first base station received load information of the second base station and based on whether the first and second base stations are provided by the same vendor, and the first base station may then use that level of confidence as a basis to control handover of the WCD.

Abstract: Adaptation of measurement procedures for cell detection and association provide more accurate and frequent reports for use by the network, to enhance cell association. A user equipment receives, within a configured measurement bandwidth, orthogonal frequency division multiplexing symbols comprising discovery reference signals (DRS). For subframes in which the DRS are transmitted, a discovery reference signal received quality (D-RSRQ) is determined from the DRS within the received symbols as a ratio of discovery reference signal received power (D-RSRP) to carrier discovery received signal strength indicator (D-RSSI), where the D-RSRP is measured in symbols containing DRS resource elements and the D-RSSI is measured in all symbols in subframes containing the DRS. For a UE configured to also measure common reference signals, non-DRS measurements are suspended upon deactivation of a secondary cell, and measurement timing of the DRS during a deactivation period is based on a measurement timing parameter.

Abstract: Methods, systems, and devices are described for wireless communication at a device. A device may distinguish a preamble sent from a device configured for a first RAT (e.g., WLAN, Wi-Fi, etc.) from a preamble sent from a device configured for a second RAT (e.g., LTE, LTE-A, LTE-U, etc.). A wireless device associated with a second RAT may transmit a dual-use preamble over a contention-based frequency channel. The dual-use preamble may function as a valid preamble for a first RAT and may be received and decoded by devices associated with the first RAT in addition to devices associated with the second RAT. The dual-use preamble may also include a signature associated with the second RAT. The signature may be embedded with the preamble such that it minimizes interference with the valid preamble and be detected by devices associated with the second RAT.
