摘要： UE that are able to cancel interference from CRS, a PDSCH, a PDCCH, or a PCFICH may do so without explicitly signaling the capability to the serving eNB. The serving eNB may transmit to the UE a plurality of cell identifiers to indicate from which cells interference should be canceled. The UE receives CRS, PDSCH, PDCCH, or PCFICH from the serving eNB and cancels CRS, PDSCH, PDCCH, or PCFICH interference, respectively from the signal received from the eNB. The UE cancels the interference from the cells that correspond to the cell identifiers. The UE may then transmit a report to the eNB with a quality measurement without the interference.

摘要： When enabled with common reference signal interference cancelation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.
摘要翻译：当使用公共参考信号干扰消除时，用户设备（UE）仍可以考虑任何取消的干扰相邻信号来计算信道状态反馈值。当在正在计算信道状态反馈值的时间内确定相邻小区正在发送数据时，UE能够导出考虑到那些被消除的干扰信号的信道状态反馈值。 UE通过获得指示相邻小区的传输调度的信号或者通过基于相邻小区的功率等级来检测传输调度来确定在指定时间期间每个相邻小区是否正在发射。如果UE在该时间段期间确定相邻小区正在发送数据，则UE将计算包括考虑被消除的干扰信号的信道状态反馈值。

摘要： A method for ranking signals isolates and cancels neighboring cells using layering. Received signals from various cells are grouped into layers, with each layer comprised of received signals which are comparable within a particular metric (such as signal strength). The signals within a particular layer may also be ranked according to a desired metric. At the beginning of a cancellation cycle the UE may perform the layering and ranking. Once the layering and ranking has been performed the UE may continue to use the layering and ranking for later rounds of cancellation, freeing up processing resources that would otherwise be dedicated to repeated ranking of received signals. After a period of time, the cancellation cycle may repeat and the layering and ranking may be performed again.

摘要： Providing for access point assisted signal acquisition for heterogeneous access point wireless networks is described herein. By way of example, a closed subscriber group (CSG) base station, such as a home NodeB (HNB) can be configured to provide temporary, limited access to a UE that is not authorized to access the HNB. Upon receiving and rejecting an access probe, the HNB can negotiate with a surrounding macro network to provide service for the UE. Further, the HNB can forward signal acquisition data, to assist in proper decoding of pilot or synchronization signals of the macro network. In particular aspects, the HNB can reduce power or blank transmissions on reserved access resources to reduce interference for the UE. By these and other disclosed mechanisms, the HNB can assist a non-CSG subscriber to obtain network service, and mitigate interference effects due to proximity to the UE.

摘要： Techniques for performing time tracking in a communication system utilizing a cyclic prefix are described. In an aspect, a receiver may perform time tracking and determine an FFT window position based on a metric related to inter-symbol interference (ISI) and inter-carrier interference (ICI). The receiver may determine an early energy for signal paths earlier than the current FFT window position, determine a late energy for signal paths later than the current FFT window position, determine the metric based on the early and late energies, compute an update amount for the FFT window position based on the metric, and update the FFT window position based on the update amount with a time tracking loop (TTL). In yet another aspect, the receiver may compute the FFT window position based on a channel impulse response (CIR) estimate directly, without using a TTL.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.

摘要： Mobile communication devices may use too much power and/or take too much time when camping on a particular mobile communication network. An apparatus may implement functions that may decrease power usage and/or decrease time usage. The apparatus may be a UE configured to measure energy levels for each frequency channel of a set of frequency channels in a frequency band to determine measured energy levels. The apparatus may also be configured to determining whether a first cell that operates using a first RAT is detected on a frequency channel of the set of frequency channels based on the measured energy levels. Additionally, the apparatus may be configured to search for a second cell that operates using a second RAT, when no cell for the first RAT is detected on the set of frequency channels, wherein the UE searches for the second cell using the measured energy levels.

摘要： A low complexity List Viterbi algorithm (LVA) for decoding tail biting convolutional codes (TBCCs) has lower complexity than a solution of running the LVA algorithm for all states. In one aspect, a low complexity LVA-TBCC process includes finding a list of states from a single Viterbi algorithm and finding a list of potential codewords for each state in the state list using the LVA. A cyclic redundancy check may prune out false solutions. The disclosed method may be applied to many communication systems to improve error performance similar to LTE downlink PBCH decoding enhancements.
