摘要： Communications by base stations in wireless communication networks may be coordinated in a manner to improve performance by mobile devices experiencing interference from non-serving base stations. In particular, base station communications may be coordinated to improve the performance of interference cancellation by mobile devices. If a user equipment (UE) experiencing interference is capable of interference cancellation, then the base stations may coordinate to increase interference to that user equipment so as to improve that UE's ability to perform interference cancellation. Base stations may also coordinate to reduce interference for a UE, regardless of the UE's ability to perform interference cancellation. Mobile device performance improvements may also be achieved by coordinating scheduling of resources by the non-serving base stations, by using communication formats compatible with interference cancellation, by spatial coordination.

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： A coax network unit (CNU) receives downstream bursts from a coax line terminal (CLT) and transmits upstream bursts to the CLT. The downstream bursts include start markers that indicate the beginnings of the downstream bursts and may also include pilot symbols. The downstream bursts are continuous across available resource elements in a matrix of subcarriers and orthogonal frequency-division multiplexing (OFDM) symbols. The available resource elements exclude resource elements in the matrix that carry the pilot symbols. The upstream bursts may include start markers indicating the beginnings of the upstream bursts and end markers indicating the ends of the upstream bursts. Respective upstream bursts are transmitted in respective groups of one or more resource blocks allocated to the CNU.

摘要： A coax network unit (CNU) receives a first plurality of orthogonal frequency-division multiplexing (OFDM) symbols from a coax line terminal (CLT). The first plurality of OFDM symbols includes continual pilot symbols on one or more subcarriers. The CNU also receives a grant from the CLT allocating a set of subcarriers within a second plurality of OFDM symbols to the CNU. The CNU transmits upstream to the CLT using the allocated set of subcarriers within the second plurality of OFDM symbols. When transmitting, the CNU places non-continual pilot symbols on regularly spaced subcarriers of the allocated set of subcarriers and does not place continual pilot symbols within the allocated set of subcarriers.

摘要： Certain aspects of the present disclosure relate to a hybrid approach for Physical Downlink Shared Channel (PDSCH) Interference Cancellation (IC). In certain aspects, if the PDSCH information is known for a serving cell but not be known for interfering cell(s), a hybrid approach that involves using Codeword-level IC (CWIC) for the serving cell and using Symbol-level IC (SLIC) for the interfering cells may be used for better IC performance. The hybrid IC approach may start with a UE attempting to decode the serving cell PDSCH. If the decode is unsuccessful, the UE may perform CWIC for the serving cell followed by SLIC using the results of the CWIC stage. After the SLIC stage, the UE may attempt to decode the serving cell PDSCH again. The UE may perform multiple operations of this method until the serving cell PDSCH is successfully decoded or a maximum number of iterations is reached.
摘要翻译：本公开的某些方面涉及物理下行链路共享信道（PDSCH）干扰消除（IC）的混合方法。在某些方面，如果PDSCH信息对于服务小区而言是已知的，但对于干扰小区而言是不知道的，则涉及使用码流级IC（CWIC）用于服务小区并使用符号级IC（SLIC ）可用于更好的IC性能。混合IC方法可以从尝试对服务小区PDSCH进行解码的UE开始。如果解码不成功，则UE可以使用CWIC级的结果为服务小区后跟SLIC执行CWIC。在SLIC阶段之后，UE可以尝试再次对服务小区PDSCH进行解码。 UE可以执行该方法的多个操作，直到服务小区PDSCH成功解码或达到最大次数。

摘要： A method of performing channel estimation includes receiving a frame that includes, for each subcarrier of a subset of subcarriers in the frame, a pair of pilot symbols in the subcarrier. The subcarriers of the subset are regularly spaced apart from one another in the frequency domain. Time-averaged channel estimates for each subcarrier of the subset are generated based on the pairs of pilot symbols. Frequency-averaged channel estimates for respective subcarriers are generated based on the time-averaged channel estimates. Interpolation is performed between respective frequency-averaged channel estimates to generate interpolated channel estimates for subcarriers between the respective subcarriers.

摘要： A receiver circuit, including a multi-stage QAM de-mapper, for receiving a QAM data signal is disclosed. A first de-mapper circuit recovers a set of encoded data bits from the QAM data signal by calculating a plurality of distances between a received QAM symbol and each of a plurality of possible constellation points. A second de-mapper circuit then generates a set of un-encoded data bits for the received QAM symbol based, at least in part, on the plurality of distances calculated by the first de-mapper circuit. The receiver circuit may further include a decoder circuit to decode the set of encoded data bits recovered by the first de-mapper circuit. The second de-mapper circuit may identify a subset of the plurality of possible constellation points based on a result of the decoding and select a constellation point that is associated with the shortest distance of the plurality of distances.
