摘要： Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques.

摘要： Mobile user equipment (MUE) can be enabled to search for and camp on a preferred node, such as a home base node (HBN), in a battery-efficient manner even when currently camped on another node, such as a macro base node (MBN). When the MBN provides good channel quality, slow rate background intra- and inter-frequency searches can discover the preferred HBN that would otherwise not be discovered or would consume excessive power with continual searching. When channel quality is fair, slow rate background inter-frequency searches can result in timely switching to the preferred HBN. Location hints that indicate proximity of the preferred HBN can be used to trigger slow rate background searches. Neighboring cell searching of neighbor cell listing (NCL) when in channel quality is fair or poor are maintained to prepare for call reselections to available node.

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： Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

摘要： A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.

摘要： Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.

摘要： Downlink codes may be chosen autonomously for femtocells in a wireless communication environment. Downlink transmissions are received from Home NodeBs that are neighbors of the femtocell and macrocell base stations near the femtocell. The downlink transmissions are evaluated to recognize a first set of detected downlink codes that each have a pilot energy above a predetermined detection threshold. An optimal downlink code is selected for use in connection with serving user equipment of the femtocell. The optimal downlink code is based upon the first set of detected downlink codes and selected as a downlink code from a set of downlink codes reserved for the femtocell. The optimal downlink code may be an available downlink code with a smallest amount of detected energy or a randomly selected downlink code from the available downlink codes.

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.
