For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and, a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

  • Patent number: 10484876
    Abstract: An access point (AP) may use historical Dynamic Frequency Selection (DFS) monitoring information to make a decision of whether to perform a DFS procedure on a particular channel. The historical information can be obtained from other APs, such as from other nearby APs. In this manner, historical DFS monitoring information, which was previously measured by the AP or by a nearby AP, can be used to improve the likelihood that a decision to perform the DFS procedure will result in a determination that a particular channel is useable.

  • Patent number: 10356789
    Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). A wireless communications system may improve UE discovery latency by dynamically selecting and switching beam forming codebooks at the millimeter wave base station and the wireless device. Selecting an optimal beam forming codebook may allow the wireless communication system to improve link margins between the base station without compromising resources. In some examples, a wireless device may determine whether the received signals from the millimeter wave base station satisfy established signal to noise (SNR) thresholds, and select an optimal beam codebook to establish communication. Additionally or alternately, the wireless device may further signal the selected beam codebook to the millimeter wave base station and direct the millimeter wave base station to adjust its codebook based on the selection.

    Abstract: Techniques for managing congestion in a computer network are described. In some examples a network node uses a dynamic moving average to determine a level of network congestion a computer network. The dynamic moving average uses a window that is dynamically resized based on the contents of the window. For example, when the contents of the half of the window containing older samples are sufficiently different from the contents of the half of the window containing newer samples, the older samples are discarded and an average is calculated using just the newer samples.
