  • Publication number: 20220386316
    Abstract: According to one configuration, a wireless network is shared amongst a hierarchal tier of users. The wireless network environment includes one or more allocation management resources (such as so-called spectrum access systems). Each of one or more wireless network service providers operating respective wireless equipment such as one or more wireless base stations relies on a respective allocation management resource to allocate wireless channels for use. If desired, a respective wireless network service provider operating respective equipment can select an appropriate channel notification mode suitable to provide notification of incumbent use and/or reassignment of wireless bandwidth to the wireless base stations. In such an instance, in the event of re-assignment due to incumbent use, the allocation management resources communicate amongst each other regarding the incumbent use/reassignment and provide protected use of newly assigned wireless bandwidth to the first wireless network service provider.

  • Publication number: 20220264287
    Abstract: In certain embodiments, a (CBSD) base station for a (CBRS) radio system transmits new information elements in an existing capability exchange message to a spectrum access system (SAS) informing the SAS as to whether the SAS should transmit a channel-change message to the base station either (i) directly (and despite of domain proxy being present in the communication path) or (ii) via a domain proxy. If and when the SAS subsequently receives notification of incumbent activity from an Environmental Sensing Capability system, the SAS transmits either a new channel-change message or includes new information elements in an existing heartbeat message to the base station either (i) directly or (ii) via the domain proxy per the capability exchange message.

  • Publication number: 20220256644
    Abstract: According to one configuration, multiple users in a tiered hierarchy share use of a wireless spectrum. For example, a spectrum access system receives a notification indicating that a first-priority tier 1 user in the hierarchy temporarily needs access to a first wireless spectrum assigned to a second-priority tier 2 user in the hierarchy. In response to the notification, the spectrum access system temporarily allocates the second-priority tier 2 user use of a second wireless spectrum. The spectrum access system protects use of the second wireless spectrum by the second-priority tier 2 user from a third-priority tier 3 user in the hierarchy. In certain instances, the one or more spectrum access systems receive the same notification of use of the first wireless spectrum by the first-priority tier 1 user. The multiple spectrum access systems not serving the second-priority tier 2 user protect the Tier 2 User from any Tier 3 Users in the hierarchy.

  • Publication number: 20210360627
    Abstract: A communication management resource receives input indicating presence of a pair of wireless stations including a first wireless station and a second wireless station in a network environment. Based on a determined amount of adjacent channel interference between the first wireless station and the second wireless station, the communication management resource generates an adjacent channel interference value. The communication management resource assigns the adjacent channel interference value to the pair of wireless stations. The adjacent channel interference value indicates an estimate of adjacent channel interference between the first wireless station and the second wireless station. In a network of wireless stations, the adjacent channel interference value is used as a basis to identify pairs of wireless stations that are susceptible to adjacent channel interference.
