摘要： Techniques for transmitting beacon signals to assist user equipments (UEs) perform cell search and techniques for detecting for beacon signals are described. In an aspect, cells may be assigned beacon patterns defined based on orthogonal grouping of subcarriers. U subcarriers usable for beacon may be arranged into G orthogonal groups, with each group including S subcarriers. different beacon patterns may be defined based on the G groups of S subcarriers. In another aspect, the cells may transmit their beacon signals at configurable transmit power levels, which may be determined based on target beacon detection performance. In yet another aspect, a UE may perform overlapping DFTs in order to capture more received power when symbol timing at the UE is not aligned with symbol timing of cells being detected. In yet another aspect, the UE may perform beacon detection with maximal likelihood decoding.

摘要： In order to cancel any interference due to the second cell signal (e.g., from a non-serving cell) from a signal received at a UE, without receiving additional control information, the UE blindly estimates parameters associated with decoding the second cell signal. This may include determining a metric based on sets of symbols associated with the cell signals in order to determine parameters for the second cell signal, e.g., the transmission mode, modulation format, and/or spatial scheme of the second cell signal. The parameters for the signal may be determined based on a comparison of the metric with a threshold. When a spatial scheme and a modulation format is unknown, the blind estimation may include determining a plurality of constellations of possible transmitted modulated symbols associated with a potential spatial scheme and modulation format combination. Interference cancellation can be performed using the constellations and a corresponding probability weight.
摘要翻译：为了从UE接收到的信号中消除由于第二小区信号（例如来自非服务小区）的任何干扰而不接收附加控制信息，UE盲目地估计与解码第二小区信号有关的参数。这可以包括基于与小区信号相关联的符号集来确定度量，以便确定第二小区信号的参数，例如第二小区信号的传输模式，调制格式和/或空间方案。可以基于度量与阈值的比较来确定信号的参数。当空间方案和调制格式未知时，盲估计可以包括确定与潜在的空间方案和调制格式组合相关联的可能传输的调制符号的多个星座。干扰消除可以使用星座和相应的概率权重进行。

摘要： Devices and methods are provided for implementing an over-the-air (OTA) broadcast of an overload indication to reduce interference levels at neighboring node(s). In one embodiment, the method involves receiving the OTA broadcast of the overload indication from a neighboring node. The method further involves performing transmit power control based upon the received overload indication to reduce Interference over Thermal (IoT) noise at the neighboring node (e.g., by adjusting the transmit power spectral density). Such a method may be performed, for example, by an access terminal or a small base node.

摘要： Systems and methodologies are described that facilitate sending a power control command in a wireless communication environment. A base station can send a power control command to a UE through resource elements reserved for at least one Physical Downlink Control Channel (PDCCH). Thus, the power control command can be punctured into a control channel element (CCE) reserved for the at least one PDCCH. Further, the base station can convey an indicator that specifies the resource elements reserved for the at least one PDCCH used for sending the power control command to the UE. Moreover, the base station can use a structure similar to a conventional (e.g., Release 8, ) PHICH structure for sending the power control command using the resource elements reserved for the at least one PDCCH. For example, the power control command can be spread using one or more Walsh codes assigned to the UE.
