摘要： Systems and methods are described that facilitate evaluating conditions of nodes (e.g., access points, access terminals, etc.) in a wireless communication environment to determine a level of disadvantage for a given node relative to other nodes. A first node may receive a resource utilization message (RxRUM) and may determine a level of disadvantage for a node that sent the RxRUM. The first node may then compare its own level of disadvantage to the sending node in order to permit a determination of an appropriate course of action in response to the RxRUM.

摘要： Aspects describe conveying unicast information and broadcast information in a resource set for a transmission request. The unicast information and broadcast information can be transmitted at substantially the same time. Power control can be applied separately to the unicast information and the broadcast information for reliable decoding. A null request can be indicated by "00" bits in a unicast portion and a zero power level in the broadcast portion.

摘要： Systems and methodologies are described that facilitate transmitting beacon symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified with carriers. In this regard, a coding scheme can be applied to a beacon message; the coding scheme can produce a plurality of beacon symbols to transmit on given subcarriers. A receiving device of the beacon symbols can decode a beacon message by receiving less than the total number of symbols in a beacon message and determining the remaining symbol subcarriers based on the linear constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy linear constraints for the symbols, and resolving time and frequency shift by detecting an offset that would result in satisfaction of the linear constraint.
摘要翻译：描述了便于发送信标消息的信标符号的系统和方法，使得符号序列可以满足可以用载波识别场元素的场的线性约束。在这方面，可以将编码方案应用于信标消息; 编码方案可以产生多个信标符号以在给定子载波上进行传输。信标符号的接收设备可以通过接收小于信标消息中的总符号数量来解码信标消息，并且基于线性约束确定剩余的符号子载波。因此，通过找出哪些符号满足符号的线性约束来解决信标的更有效的解码以及解析信标模糊度，以及通过检测将导致满足线性约束的偏移来解决时间和频率偏移。

摘要： Devices and methods are provided for adapting to interference in a spectrum shared by a WAN macro cell and a femto cell. In particular, described herein are techniques for adapting to the presence of a jamming WAN access terminal (AT) by avoiding or selectively utilizing those bandwidth portions jammed by the WAN AT/AP. For example, the technique may involve intercepting a control message from the WAN AP to the WAN AT, and determining a spectrum resource that the WAN AT will use to communicate with the WAN AP based at least in part on information (e.g., a Cell Radio Network Temporary Identifier, a Media Access Control Identifier, etc.) in the control message.

摘要： Tones within a channel can be selected randomly and/or based on orthogonal tone selection. Random selection can include selecting tones randomly from a fixed set, which is referred to as channelized tone selection. Channelized tone selection can be chosen if a critical tone exists. Random selection can also include selecting resources randomly from the total number of resources available, which is referred to as non-channelized tone selection. Orthogonal tone selection can be chosen to mitigate the probability of receiver desensitization and/or to attempt to mitigate interference.

摘要： Systems and methodologies are described for detecting impulsive interference of pilot signals in wireless communications networks and accounting for such interference in estimating data channels to decode the pilot signals. Portions of a received pilot signal can be compared to other portions to create correlated subsets of similar portions. The number of portions in a subset can indicate a high likelihood of non-interference, and portions that are not in the subsets can be disregarded or weighted less in estimating channels for decoding. In cases of ambiguous subsets or portions, one or more subsets/portions can each be used to estimate the channel and data can be decoded multiple times. The decoding that results in a higher decoding metric can be selected. Additionally, systems and methodologies for inserting pilot signals within data are described.

摘要： Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

摘要： A method, an apparatus, and a computer program product are provided. The apparatus determines a channel gain to a second wireless device with which the first wireless device is communicating. In addition, the apparatus determines interferer backoff information that ensures an interference level at the first wireless device such that a signal received from the second wireless device can be decoded reliably.

摘要： Chase combining gains for receiving a scrambled broadcast channel can be achieved even when a portion of each received channel coded transmission contains a portion that varies. A set of possible difference values for this varying portion, such as for a system frame number, provides hypotheses, each having a corresponding probability. One or more of the hypotheses are selected by rank order for adjusting a corresponding received coded transmission so that two or more channel coded transmissions can be combined and blind decoded until one of the hypotheses are confirmed.

摘要： Systems and methods are described to supply positioning reference signal (PRS) in a telecommunication system. A base station supplies a PRS sequence according at least to a time-frequency pattern of modulation symbols, wherein the time-frequency pattern assigns a modulation symbol to each frequency tone in a block of time-frequency resources allocated to transmit PRS. The base station associates a modulation symbol in the time-frequency pattern with a reference symbol in the PRS sequence through a mapping that represents the time-frequency pattern. The PRS sequence is conveyed to user equipment through delivery of a set of modulation symbols established through the mapping. Different time-frequency patterns can be exploited based on time-structure of a radio sub-frame. The user equipment receives the PRS sequence according to at least the time-frequency pattern of modulation symbols and utilizes at least the PRS sequence as part of a process to produce a location estimate.
