  • Patent number: 10292125
    Abstract: Methods of location tracking and location resolution are discussed for network architectures which allow devices, such as User Equipment, to communicate with different networks (e.g., different network operators) without roaming. A hierarchical Connectivity Management (CM) is provided which allows for location tracking and location resolution as devices move within and between different network boundaries. Such a hierarchy includes a Global CM which provides inter network CM, and domain CM which provides intra network CM. Some embodiments utilize virtual user CMs within the domain. In some embodiments the global CM is implemented by a third party. In other embodiments different networks inter operate by utilizing virtual network slices over non-owned infrastructure to provide what appears to be a global network by each operator.

  • Patent number: 10284322
    Abstract: In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

  • Patent number: 10277374
    Abstract: Aspects of the invention include methods and devices for inserting data and pilot symbols into Orthogonal Frequency Division Multiplexing (OFDM) frames having a time domain and a frequency domain. A method involves inserting in at least one zone of a first type a two dimensional array of data and pilot symbols in time and frequency and inserting in at least one zone of a second type a two dimensional array of data and pilot symbols in time and frequency. In some implementations the zone of the first type comprises common pilot symbols that can be detected by all receivers receiving the OFDM frame. In some implementations the zone of the second type comprises dedicated pilot symbols that are only detectable by a receiver that is aware of pre-processing used to encode the dedicated pilot symbols.

  • Patent number: 10263677
    Abstract: Aspects of the present invention provide additional MAC functionality to support the PHY features of a wireless communication system framework. The additional MAC functionality aids in enabling feedback from wireless terminals to base stations. In some aspects of the invention the feedback is provided on an allocated feedback channel. In other aspects of the invention the feedback is provided by MAC protocol data units (PDU) in a header, mini-header, or subheader. The feedback may be transmitted from the wireless terminal to the base station autonomously by the wireless terminal or in response to an indication from the base station that feedback is requested. Aspects of the invention also provide for allocating feedback resources to form a dedicated feedback channel. One or more of these enhancements is included in a given implementation. Base stations and wireless terminals are also described upon which methods described herein can be implemented.

  • Publication number: 20190109252
    Abstract: Devices converting light to electricity (such as solar cells or photodetectors) including a heavily-doped p-type a-SiCy:H and an i-MgxCd1?xTe/n-CdTe/N—Mg0.24Cd0.76Te double heterostructure (DH), with power conversion efficiency of as high as 17%, Voc as high as 1.096 V, and all operational characteristics being substantially better than those of monocrystalline solar cells known to-date. The a-SiCy:H layer is configured to enable high built-in potential while, at the same time, allowing the doped absorber to maintain a very long carry lifetime. In comparison, similar undoped CdTe/MgxCd1?xTe DH designs reveal a long carrier lifetime of 3.6 ?s and an interface recommendation velocity of 1.2 cm/s, which are lower than the record values reported for GaAs/Al0.5Ga0.5As (18 cm/s) and GaAs/Ga0.5In0.5P (1.5 cm/s) DHs.

  • Patent number: 10257762
    Abstract: Embodiments are provided for a location-based network discovery and connection establishment, which take advantage of location/positioning technology of user equipment (UE) and resolve issues above of the blind search approaches. The location-based network discovery and connection establishment schemes use UE location information and a network access MAP to speed up network discovery, and remove the need for continuous search and measurement by the UE. The schemes also reduce the search space. A wireless network access map (MAP) is provided to the UE. The UE uses the MAP information with UE current location information to reduce the search space and speed up network discovery and radio connection establishment with the network. Network operators can use this network access MAP to control the network access and manage the network load distribution. The network access MAP can be customized for each UE.

  • Patent number: 10237106
    Abstract: Methods and systems are provided that enable an OFDM transmitter to be used for transmitting conventional OFDM or a form of transformed OFDM. A technique is provided for transforming a coded and modulated sequence of samples prior to an IFFT that enables the transformed sequence of samples to be transmitted using conventional OFDM or transformed OFDM. The selection of a transform function for transforming the coded and modulated sequence of samples may be based on optimizing the transform function for particular operating conditions between the transmitter and receiver. In some embodiments of the invention OFDM and time transformed OFDM are multiplexed in time and/or frequency in a transmission frame. In some embodiments of the invention a pilot pattern is provided in which the pilot are sent using OFDM and data is sent using OFDM and/or transformed OFDM.

  • Patent number: 10212017
    Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-1 and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

  • Patent number: 10212585
    Abstract: Wireless network specific (WN-specific) key can be used to provide access protection over the radio access link. A WN-specific key may be associated with (or assigned to) a wireless network, and distributed to access points of the wireless network, as well as to user equipments (UEs) following UE authentication. The WN-specific key is then used to encrypt/decrypt data transported over the radio access link. The WN-specific key can be used in conjunction with the UE-specific keys to provide multi-level access protection. In some embodiments, WN-specific keys are shared between neighboring wireless networks to reduce the frequency of key exchanges during handovers. Service-specific keys may be used to provide access protection to machine to machine (M2M) services. Group-specific keys may be used to provide access protection to traffic communicated between members of a private social network.
