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.

Abstract: A wireless system is shared amongst a hierarchal tier of entities. A communication management resource receives notification that a second-tier priority entity has been allocated use of a second wireless spectrum as a replacement to first wireless spectrum. In one embodiment, the first wireless spectrum is revoked from the second-tier priority entity based on use of the first wireless spectrum by a first-tier priority entity (such as incumbent entity). The communication management resource controls a wireless transmit power level of a third-tier priority entity in the hierarchy to provide protected use of the second wireless spectrum by the second-tier priority entity. According to one configuration, the communication management resource controls a power level of wireless communications transmitted by a wireless base station operated by the third-tier priority entity.

Abstract: Methods and apparatus for implementing a spectrum access controller (SAC) which protects a protected entity from excessive interference are described. A spectrum access controller (SAC) divides the coverage contour of the entity to be protected into geospatial zones called protection zones. Each protection zone is protected against interference from a neighboring area called an interference neighborhood. Each interference neighborhood is divided into interference zones based on their interference potential or distance from the protection zone. Potential interferers are grouped based on their location in the interference zones or interference potential. The interference quota for the protection zone is divided among the potential interferers in each group/zone. The quota may be divided unequally among groups/zones, e.g., based on their overall interference potential or proximity to the protection zone, or number of interferers.

Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus configured to enable wireless stations to use their shared spectrum grants proximate a priority/incumbent user of the shared spectrum by generating a propagation model of the priority/incumbent user, determining a potential interference therewith by each of at least one group of similarly located wireless stations proximate the priority user, determining a modification to a spectrum grant for each wireless station group that would avoid interference with the priority/incumbent user by the respective wireless stations of the group, and updating the spectrum grants of each wireless station in a wireless station group using the determined spectrum grant modification associated with the wireless station group.

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.

Abstract: Various embodiments disclosed herein provide for a closed loop Listen Before Talk (LBT) which is a coexistence mechanism used by wireless technologies such as Wi-Fi, to access unlicensed shared spectrum, such as the ISM UNII bands (5 GHz). The embodiments disclosed herein enable a base station to coordinate the LBT process at both the base station and a receiver in order to avoid hidden node interference where the interfering nodes are outside the sensing range of the transmitting node. The base station device can send an LBT trigger to the receiver to synchronize the clear channel assessments that are performed at each device to determine if there is any activity on the channel. The receiving device can send back a report to the base station device, and if no activity on the channel is detected, the base station device can schedule a transmission on the channel.

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.
