    • Wireless channel interference information is determined (e.g., a background interference matrix BIM constructed from multiple user equipment measurements). Reliability of the interference information is classified and sent with the interference information to a neighbor network access node such as a HeNB. In various embodiments there are three layers of reliability, the above being the first. The second layer utilizes variability of a plurality of such reliability indications received from the same neighbor HeNB, which is updated as new interference information and reliability indications are received from that same neighbor HeNB. The third layer utilizes a peer review/update process on the neighbor HeNBs themselves, where each HeNB's performance is shared among all and updated by one another as different HeNBs utilize one another's BIM and assesses how reliably it reflected actual interference conditions. This addresses concerns for data/source reliability since communication interfaces among HeNB groups may not be controlled by a single network operator.
    • 确定无线信道干扰信息(例如,由多个用户设备测量构成的背景干扰矩阵BIM)。 干扰信息的可靠性被分类并与干扰信息一起发送到诸如HeNB的邻居网络接入节点。 在各种实施例中,存在三层可靠性,上述是第一层。 第二层利用从相同的相邻HeNB接收的多个这样的可靠性指示的可变性,其被更新为新的干扰信息,并且从相同的邻居HeNB接收可靠性指示。 第三层利用对邻居HeNB本身的对等审查/更新过程,其中每个HeNB的性能由所有HeNB彼此共享并且彼此更新,因为HeNB不同的BNB利用彼此的BIM并且评估它们如何可靠地反映实际的干扰条件。 这解决了数据/源可靠性的问题,因为HeNB组之间的通信接口可能不被单个网络运营商控制。
