  • Publication number: 20200162929
    Abstract: Methods and apparatus for protecting a dynamic protection area (DPA). In one embodiment, an electronic device detects that the DPA is activated in the vicinity of a location recorded within a geolocation database. The electronic device compares a threshold representing acceptable interference and an estimated aggregate interference by the set of CBSDs to a set of points within the DPA. The electronic device moderates transmission by one or more CBSDs within the set of CBSDs when the estimated aggregate interference is higher than what is acceptable to the DPA.

  • Publication number: 20190288894
    Abstract: Methods and systems for multi-protocol beacon operation in shared spectrum (unlicensed band) are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. In one application, an LTE transmitter (LTE-U) uses LTE subcarriers to generate an interpolated 802.11 (e.g. Wi-Fi) beacon transmission that can be understood by Wi-Fi receivers, for example to reserve the channel for a subsequent LTE transmission. For instance a W-LAN preamble is generated where STF and LTF fields consist in respectively 12 and 52 subcarriers mapped at their respective frequency locations among the 2048 LTE subcarriers with the remaining subcarriers set to 0. In some implementations, the use of beacons can be useful in implementations where it is desirable to gain prioritized access to reserve the channel.

    Abstract: Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to generate and/or transmit LTE information using LTE subcarriers located in unused portion(s) of the Wi-Fi system bandwidth independently of or in addition to transmitting Wi-Fi or LTE information using LTE subcarriers located in portions of the Wi-Fi system bandwidth normally occupied by Wi-Fi subcarriers.

  • Publication number: 20190245726
    Abstract: Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, multi-protocol transmissions as described herein may be performed sequentially (e.g. in a time division multiplexing fashion) or concurrently (e.g. during the same or an overlapping time interval). For concurrent transmissions, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to use different subsets of the LTE subcarriers for concurrent LTE and 802.11 transmissions that can respectively be decoded by LTE and 802.11 receivers.
