摘要： Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

摘要： Systems, devices, and methods for adjusting a transmission power at a femto node are described herein. According to the systems, devices, and methods herein, a measurement of a signal transmitted from a transmitting node may be communicated to the femto node, for example from a user equipment or a neighboring femto node, for use in adjusting the power. The transmitting node may comprise the femto node, a macro node, or a neighboring femto node. In addition, statistics regarding such measurements may be communicated to the femto node for use in adjusting the power. The femto node may also adjust the power based on unsuccessful registration attempts or interference communications received at the femto node.

摘要： A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.

摘要： Techniques are provided for overcoming uplink (UL) interference at a femtocell or the like by modifying the estimated interference-plus-noise power in UL power control. In one example, the modification can be specified by a method, operable by a network entity, that may involve determining a level of excess received interference based at least in part on out-of-cell interference (Ioc). In another example, the modification can be specified by a method, operable by a network entity, that may involve determining a difference between the downlink transmit powers of the high-speed downlink packet access (HSDPA) serving and non-serving cells, with which the UE are in soft handover (SHO) in uplink and is served by the HSDPA serving cell in downlink.

摘要： A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

摘要： Grant channel resources are allocated based on the number of access terminals that use different types of transmission time intervals (TTIs) for data transmissions. For example, if the number of access terminals using a first type of TTI exceeds the number of access terminals using a second type of TTI, more grant channel resources are allocated to the access terminals that use the first type of TTI.

摘要： An access point transmits cell information via a physical layer channel. In some cases, the cell information sent on the physical layer channel comprises a physical layer identifier. For example, a physical layer channel may be modulated based on a cell identifier and/or a closed subscriber group identifier associated with the access point. Through the use of this cell information, an access point may be quickly identified for mobility and/or interference management operations. In addition, this cell information may be used for finger-printing operations.

摘要： A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.
