  • Patent number: 10295647
    Abstract: Systems, methods, and devices are disclosed for enabling a mobile device with limited RF capability to obtain accurate directions for finding an object or asset via a multiple-antenna locator device. The mobile device generates a request to the locator device to obtain directions to find the asset. A request can also be made to obtain the mobile device's own location from the multiple-antenna locator device which has an antenna array and is in a fixed location that has good RF visibility. The locator device identifies the target asset and receives an RF signal from it using the antenna array. The signal is detected at each antenna and phase samples are recorded. The phase sample data is used in angle-related functions, such as angle of arrival and angle of departure algorithms to calculate the direction of the asset.

    Abstract: Techniques and devices are described for wireless communication. A base station may determine a parameter associated with a transmission such as hybrid automatic repeat request (HARQ) feedback, a signal-to-noise ratio, or a determination regarding whether the transmission was successfully decoded. The base station may then determine a contention window adjustment value based on the parameter. The base station may then apply weighting factor (e.g., based on the time of the transmission, a number of devices being served, aspects of the transmission parameter, etc.) to the contention window adjustment value may adjust a contention window size for a second transmission based on the weighted contention window adjustment value (and, in some cases, other weighted adjustments based on other transmissions).

  • Patent number: 10285059
    Abstract: After a failed association attempt by an electronic device, an access point may facilitate trouble shooting by determining information associated with the electronic device. For example, the access point may receive at least an instruction from a computer associated with a network administrator to create a personal WLAN having a user-specific SSID. This user-specific SSID may correspond to a user of the electronic device (such as the user's name) or may be independently provided to the user by the network administrator. Then, the electronic device may associate with the access point to join the personal WLAN. In response, the access point may determine the MAC address of the electronic device. Next, the access point may provide the MAC address to the computer, so that the network administrator can identify the electronic device in the WLAN and/or can obtain additional information that can be used to solve the association problem.

  • Patent number: 10211957
    Abstract: A simultaneous information and energy transfer method and system with a guard interval signal are provided. The method comprises the steps of generating, by a transmitting terminal, a controllable guard interval signal according to the current energy demand and environment conditions for channel transmission. The system comprises a transmitting terminal configured to generate a controllable guard interval signal. In the system and method, the guard interval time is fully utilized to transfer a guard interval signal with controllable amount of energy, which not only prevents intersymbol interference, but also provides controllable energy signals within the guard interval time at the same time, thus improving the energy transfer performance of the system and reducing the probability that the receiving terminal is unable to operate normally due to energy shortage. The present invention can be widely applied to a variety of simultaneous wireless information and energy transfer systems.

  • Patent number: 10212640
    Abstract: A Long Term Evolution (LTE) network connects wireless communication devices to an Internet. In the LTE network, a Packet Data Network Gateway (P-GW) exchanges user communications between the wireless communication devices and the Internet. The P-GW determines a number of additional wireless communication devices the P-GW can serve and transfers the number to a Mobility Management Entity (MME). The MME allocates a new wireless communication device to the P-GW based on the number of additional wireless communication devices reported by the P-GW. The MME may redirect one of the wireless communication devices to the P-GW based on the number.

    Abstract: A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group.

  • Patent number: 10193728
    Abstract: Technologies are generally provided to enable the peak-to-average power ratio (PAPR) in OFDM communication systems to be adjusted to a particular level. In some examples, an N-symbol transmission vector may be partitioned into k equal partitions, a Fast Fourier Transform (FFT) may be performed on each partition, and an interleaving union of FFT results may be generated. The results of the interleaving union may be used for transmission after mapping them to the M subcarriers and performing an M-point IFFT. On the receiver side, FFT may be performed on M subcarriers, where each of L end user devices may be assigned N subcarriers out of M=N*L available subcarriers. The N subcarriers of the FFT results may be de-mapped and subjected to an interleaving partition. Subsequently, an Inverse FFT (IFFT) may be performed on each partition and results of the IFFT operation employed for symbol detection.
