摘要： Prior to a change in a configuration, such as a change to the carrier frequency, bandwidth, base station type, and so forth of the base station, the base station can inform a subscriber station to prepare for the reconfiguration by sending a message to the subscriber station. The message informs the subscriber station regarding the change in configuration and a timing regarding the change. The base station can command the subscriber station to handover to the serving base station with the new configuration or the subscriber station can choose to handover to the serving base station with the new configuration. The subscriber station can perform network reentry to the serving base station with the new configuration at the time of or after the new configuration is effective. A communication context between the stations can be maintained and the network reentry can be optimized by omitting one or more operation procedures.

摘要： When a subscriber station (SS) encounters interference caused an interfering base station (BS), the interference can be mitigated regardless of whether the interfering base station is a CSG-Closed BS or whether the SS is connected to a serving BS. If the SS is not connected to a serving BS and cannot access the interfering BS, the SS will signal the interfering BS directly to request the interfering BS to perform IM. If the SS is a legal user, and conditions to initiate IM are met, the interfering BS will perform IM until conditions to terminate IM are met. If the SS is connected to a serving BS, the serving BS will request the interfering BS to perform or terminate interference mitigation (IM) on behalf of the SS if certain conditions are satisfied.
摘要翻译：当用户站（SS）遇到造成干扰基站（BS）的干扰时，可以减轻干扰，而不管干扰基站是否为CSG封闭BS，或SS是否连接到服务BS。如果SS未连接到服务BS并且不能访问干扰BS，则SS将直接通知干扰BS以请求干扰BS执行IM。如果SS是合法用户，并且满足启动IM的条件，则干扰BS将执行IM直到满足终止IM的条件。如果SS连接到服务BS，则如果满足某些条件，服务BS将请求干扰BS代表SS执行或终止干扰减轻（IM）。
