摘要： A method for wireless communications where a control packet is not transmitted for all transmissions of a new data packet. A control packet is only sent with a retransmission of a data packet where the previously transmitted data packet is not completely received. The control packet contains information related to a previously transmitted data packet. The previously transmitted data packet and the retransmission data packet are derived from common data. The common data is derived based on the information related to the previously transmitted data packet, wherein the previously transmitted data packet and the retransmission data packet are associated with a series of data packets.

摘要： Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference.

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： 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： Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

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 cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e.g., Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.
