摘要： Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.

摘要： A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.

摘要： Transmit power for a user equipment (UE) is set by a Home NodeB (HNB) in response to interference at a nearby macrocell. The HNB monitors an interference level to the macrocell from a UE communicating with the HNB. An acceptable transmit power for the UE is determined by the HNB in response to the interference level. A power change indicator is transmitted from the HNB to the UE to adjust the transmit power of the UE. In some cases, the interference may be estimated from a busy indicator from the macrocell and the HNB sends a modified version of the busy indicator to the UE to adjust the transmit power of the UE. In other cases, the HNB estimates a path loss for the UE based on received signal power from the macrocell and signals a transmit power change to the UE, if needed, based on the estimated path loss.

摘要： Transmissions of beacons by a set of access points (e.g., femtocells) are synchronized to facilitate discovery of the access points by an access terminal moving through the coverage areas of the access points. In some embodiments, periodic beacon transmissions are synchronized across all of the femtocells of a set of femtocells such that each femtocell transmits a beacon signal according to a similar pattern and at the same time. In some embodiments, an opportunistic beacon control scheme involves commencing beacon transmissions by at least one femtocell of a set of femtocells upon determining that an access terminal has communicated with one or more of the femtocells.
