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： 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.

摘要： In release 8 of the LTE standard ("Rel-8"), a control channel and its associated data channel for downlink may be found in the same subframe. However, decoding of the control channel may be difficult if there is strong interference from different cells (e.g., due to interference from strong/dominant interfering cells). Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). For example, cells may partition subframes to avoid interference. For some embodiments, allocating resources for a downlink data channel on one subframe may come from a PDCCH on a different subframe, which can be referred to as a cross-subframe assignment. Certain aspects of the present disclosure provide subframe-specific search spaces that may be used when there is at least one cross-subframe assignment in a subframe.
摘要翻译：在LTE标准（“Rel-8”）的版本8中，可以在同一子帧中找到用于下行链路的控制信道及其相关联的数据信道。然而，如果存在来自不同小区的强干扰（例如，由于来自强/主导干扰小区的干扰），则控制信道的解码可能是困难的。可以通过执行小区间干扰协调（ICIC）来支持主要干扰场景中的通信。例如，单元可以分割子帧以避免干扰。对于一些实施例，在一个子帧上为下行链路数据信道分配资源可以来自不同子帧上的PDCCH，其可以被称为跨子帧分配。本公开的某些方面提供了子帧专用的搜索空间，其可以在子帧中存在至少一个跨子帧分配时使用。

摘要： Systems and methods for facilitating inter-cell interference coordination using resource partitioning are described. A UE may receive or determine information related to received interference and/or future scheduling. The information may be communicated to a serving base station, which may use the information to allocate uplink or downlink resources between cells. The uplink and/or downlink resource may be partitioned in subbands to mitigate interference from adjacent network nodes. The eNBs may communicate, such as directly, via a backhaul connection, and/or between UEs to configure interference coordination and signaling.

摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

摘要： In a wireless network (100) with HSDPA-enabled user equipment devices (130), the base transceiver station (120) transmits to each HSDPA-enabled UE information regarding allocation of HSDPA codes and associated modulation techniques for other HSDPA-enabled UEs. Using this additional control information, each UE configures decision feedback filter of its equalizer to reduce inter-user interference. The additional control information may be transmitted in a packet (300) that includes a CRC portion (310) with the packet's CRC masked by a common ID, which is known to the HSDPA-enabled UEs. To reduce the number of bits needed to transmit the additional control information, the HSDPA codes used with a particular modulation technique are allocated consecutively. For each modulation technique, only the beginning code and the total number of codes need be known to the UEs. The number of codes used with each modulation technique may be allowed to change once in several TTIs.
摘要翻译：在具有支持HSDPA的用户设备（130）的无线网络（100）中，基站收发器（120）向支持HSDPA的每个UE发送关于其他支持HSDPA的UE的HSDPA代码分配和相关调制技术的信息。使用该附加控制信息，每个UE配置其均衡器的判决反馈滤波器以减少用户间干扰。附加控制信息可以在包括CRC部分（310）的分组（300）中发送，其中分组的CRC由公共ID掩蔽，这是启用HSDPA的UE已知的。为了减少发送附加控制信息所需的比特数，与特定调制技术一起使用的HSDPA码被连续分配。对于每个调制技术，只有起始码和代码总数需要为UE所知。可以允许每个调制技术使用的代码数量在几个TTI中改变一次。

摘要： Techniques for transmitting data in a manner to facilitate equalization at a receiver are described. Guard intervals are appended to data blocks such that each data block has a guard interval at the beginning of the data block and a guard interval at the end of the data block. Each guard interval may be discontinuous transmission (DTX), a polyphase sequence, or some other known sequence. Pilot is appended to each set of at least one data block. The data blocks, pilot, and guard intervals may be sent using various slot structures and are processed for transmission. The processing may include mapping the data blocks to at least one physical channel, channelizing the data blocks for each physical channel with a channelization code, combining all physical channels, and scrambling the combined data, pilot, and guard intervals with a scrambling code.
