Patents by Inventor Kari Juhani Rikkinen

Kari Juhani Rikkinen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9591673
    Abstract: A method and apparatus are therefore provided that may enable the provision of M2M communication in a wireless network environment. In this regard, for example, relatively low power devices (specifically referencing low transmission power) such as sensors or other machines in an M2M system may be enabled to initiate communication with a network through a mobile terminal in a more reliable and robust manner. The machine may transmit a busy-signal to request a reservation of a machine access slot on a machine access control channel to reserve the slot before transmitting any machine information or data to reduce the likelihood of collisions with other machines. Once the machine has reserved the machine access slot, the machine may transmit identification information via randomly selected frequency division multiplexed or code division multiplexed resources to further reduce the likelihood of collisions with other machines. Thus, delays in establishing connections may be reduced or eliminated.

  • Patent number: 9338820
    Abstract: An apparatus for providing machine-to-machine communication in a wireless network may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least providing wireless network resources to enable direct downlink communication from a wireless network access point to a relatively low power communication device, allocating wireless network resources to enable uplink data to be provided from the relatively low power communication device to a mobile gateway device within communication range of the relatively low power communication device and utilizing wireless network resources to receive the uplink data from the mobile gateway device at the wireless network access point. A corresponding method and computer program product are also provided.

  • Patent number: 9049666
    Abstract: A method and apparatus are provided that may enable the provision of machine to machine (M2M) communication in a wireless network environment. In this regard, for example, relatively low power devices (specifically referencing low transmission power) such as sensors or other machines in an M2M system may be enabled to communicate with a mobile terminal via a first carrier when the power ratio between the average received machine power and the average downlink received cellular power is below a threshold value and communicate with the mobile terminal via a second carrier if the power ratio exceeds the threshold value. Thus, only one carrier may be needed by devices in such an environment in order to perform M2M communication.

  • Publication number: 20150131491
    Abstract: The present invention relates to methods, apparatuses and computer program products for use in bi-directional channel tracking. The invention includes allocating, at a first network entity, a sub-carrier in a frequency domain for transmitting a tone to a second network entity, prohibiting, at the first network entity, receiving signals on the sub-carrier allocated for transmitting the tone, estimating, at the first network entity, a channel of residual self-interference based on the transmitted tone.

  • Publication number: 20150043456
    Abstract: A wireless communications method comprises: acquiring, by a radio apparatus, information indicating a frequency hopping pattern for control data in order to perform communication of the control data on at least one frequency resource unit hopping in frequency, wherein the frequency hopping pattern defines a control data band within the shared spectrum; acquiring knowledge of a user data band defined as a function of the control data band according to a predetermined criterion in order to per-form communication of user data on at least one free frequency resource unit within the user data band, wherein the user data band is within the shared spectrum and at least partly overlapping with the control data band; acquiring knowledge of a total frequency band comprising the control data band and the user data band; and causing communication of both the control data and the user data on the total frequency band.
