摘要： A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

摘要： Certain aspects of the present disclosure relate to a method for uplink wireless communications. In one aspect, a diversity scheme may be selectively and adaptively applied to an uplink transmission based on a determination of whether the uplink transmission comprises one or more orphan symbols. According to an aspect, the determination is made based on whether a sounding reference signal is received in the uplink subframe and whether the uplink subframe is configured with a normal or extended cyclic prefix.

摘要： Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.

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 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.
