    摘要: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

    摘要: Disclosed are example embodiments of systems and methods for an interference imbalance manager (IIM). The method includes an outer loop that goes over the K subcarrier sets ki and an inner loop that goes over the M dominant intra-frequency cells that IC are performed on, for each subcarrier set ki the noise plus interference power estimate of that set is initialized by N by setting: N(ki)=N. The method includes, for each subcarrier set ki the IIM determine when the pilots of each cell m collide with that subcarrier set. When there is no collision, the interference plus noise of that set N(ki) is not adjusted. When there is a collision the interference plus noise of that set N(ki) is adjusted by removing the power contribution Em of that cell by applying the correction: N(ki)=N(ki)−Em. The method includes looping over all considered cells M and when all adjustments are complete to N(ki) for subcarrier set ki the program provides the adjusted N(ki) output and exits the m loop.

    摘要: An information handling system includes a transceiver and a processor. The processor detects a first RF signal of the RF signals received by the transceiver from a first access point (AP), and determines whether an energy level for the first RF signal is above a energy level threshold. If so, the processor determines whether basic service set (BSS) color of the first RF signal is the same as BSS color of a second RF signal from a second AP. If not, the RF signal is coming from a different network. The processor calculates distance to the second AP, determines and configures receive sensitivity energy level threshold based on the calculated distance. If the energy level of the first RF signal is less than the receive sensitivity energy level threshold, the processor continues to receive RF signals from the second AP, and continue to reject RF signals from the interfering network.

    摘要: Systems, methods, and computer-readable media for improving resource management in Citizens Broadband Radio Service (CBRS) networks include a Spectrum Access System (SAS) in coordination with one or more CBRS devices (CBSDs) and a Digital Network Architecture center (DNA-C). Resource allocation decisions can be based on one or more policies such as a priority, a preemption capability index and/or a preemption vulnerability index associated with the CBSDs. Resource allocation can also be based on inter-access point (AP) coordination between two or more CBSDs and comparative performance indicators of the two or more CBSDs. Managing interference between two or more groups of CBSDs can be based on the inter-AP coordination and group identifiers associated with the two or more groups. Bandwidth allocation can be modified to the two or more CBSDs and seamless transition can be implemented using timers.

    摘要: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to measure self-interference between multiple transmission reception points (TRPs) of the UE and initiate sidelink full duplex communications based on the measured self-interference. The UE may transmit a message to a base station to request resources for sidelink communications by the UE and indicate an intended self-interference measurement by the UE using the resources. The base station may transmit a grant scheduling the resources for the self-interference measurement by the UE. The UE may measure interference between a TRP of the UE that is configured for transmission and a TRP of the UE that is configured for reception using the scheduled resources. The UE may transmit a sidelink feedback message indicating resources that are available for sidelink full duplex communications by the UE based on the measured self-interference.
