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.
摘要翻译：能够消除来自CRS，PDSCH，PDCCH或PCFICH的干扰的UE可以在不向服务eNB明确地发送能力的情况下这样做。服务eNB可以向UE发送多个小区标识符，以指示哪个小区应该取消干扰。 UE从服务eNB接收CRS，PDSCH，PDCCH或PCFICH，并分别从eNB接收的信号中取消CRS，PDSCH，PDCCH或PCFICH干扰。 UE消除来自对应于小区标识符的小区的干扰。然后，UE可以在没有干扰的情况下以质量测量方式向eNB发送报告。

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： Systems and methodologies are described that facilitate employing downlink precoding based on uplink sounding channel measurement and channel reciprocity in time division duplex or time division multiplex systems. In particular, mechanism are provided that enable downlink precoding in situations where user equipment antenna configuration includes an unequal number of transmit chains and receive chains. A mobile device transmits modulated sounding reference signals on each antenna during a calibration stage. The mobile device then transmits non-modulated sounding reference signals during a normal mode. A base station utilizes the modulated and non-modulated sounding reference signals to restore a downlink channel estimate employed in downlink precoding.

摘要： When there are different power classes of base stations (BSs), there may be a need to coordinate transmission from the different BSs to reduce interference to a user equipment (UE) on both control channels and data channels. There are different ways of coordination. For some embodiments, time division multiplex (TDM) resource partitioning may be performed across BSs on a subframe level. TDM resource partitioning may avoid control channel interference since resource mapping on time and frequency for control channels may span the whole frequency domain. However, the data rate for the UE may be limited due to the TDM partitioning of subframes. In other words, a limitation may derive from control channel interference coordination. For some embodiments, a UE may transmit and/or receive in subframes other than the ones partitioned for the UE.
摘要翻译：当存在基站（BS）的不同功率等级时，可能需要协调来自不同BS的传输，以减少对控制信道和数据信道上的用户设备（UE）的干扰。有不同的协调方式。对于一些实施例，可以在子帧级别上跨越BS执行时分复用（TDM）资源划分。 TDM资源分配可以避免控制信道干扰，因为控制信道的时间和频率上的资源映射可能跨越整个频域。然而，由于子帧的TDM划分，UE的数据速率可能受到限制。换句话说，限制可以来自控制信道干扰协调。对于一些实施例，UE可以在除了为UE分配的子帧之外的子帧中发送和/或接收。

摘要： Techniques for supporting communication with user equipment (UEs) of different types on a plurality of system bandwidths are described. UEs of each type may operate on one or more available system bandwidths. Resources assigned to a UE may be conveyed by a resource allocation field of a control message sent to the UE. The resource allocation field may have different configurations (e.g., different sizes and/or interpretations) for different system bandwidths. In one design, the resource allocation field and the control message sent to the UE have different sizes for the plurality of system bandwidths. A base station may determine the size of the resource allocation field based on a system bandwidth selected for the UE. In another design, the resource allocation field may have a same size but different interpretations (e.g., different resource mappings) for the plurality of system bandwidths.

摘要： In a Time Division Duplex (TDD) system, downlink and uplink communications share the same bandwidth but occupy different subframes. When the downlink has more subframes than the uplink, special treatment on user equipment (UE) ACK/NACK feedback is needed. One uplink may need to ACK multiple downlink subframes. A downlink association without unnecessary ACK/NACK resources sets accounts for subframes for which ACK feedback is not desired. Examples of such subframes include: a blank subframe; an almost blank subframe where only a cell specific Reference Signal (RS) is transmitted; a Time Division Multiplex (TDM) partition in which an evolved NodeB (eNB) only transmits a Physical Downlink Shared Channel (PDSCH) or a Physical Downlink Control Channel (PDCCH) indicating Semi-persistent scheduling (SPS) at certain downlink subframes; a Downlink Pilot Timeslot (DwPTS) with a certain special subframe configuration where an eNB does not send the PDSCH and the UE is not in SPS active mode in the DwPTS; and a Multi-Media Broadcast over a Single Frequency Network (MBSFN) subframe when the UE is not in SPS active mode in the MBSFN subframe.
摘要翻译：在时分双工（TDD）系统中，下行链路和上行链路通信共享相同的带宽，但占用不同的子帧。当下行链路具有比上行链路更多的子帧时，需要对用户设备（UE）ACK / NACK反馈进行特殊处理。一个上行链路可能需要ACK多个下行链路子帧。没有不必要的ACK / NACK资源的下行链路关联集合对不希望ACK反馈的子帧进行计费。这样的子帧的示例包括：空白子帧; 几乎空白的子帧，其中仅发送小区特定参考信号（RS）; 时分复用（TDM）分区，其中演进的节点B（eNB）仅在某些下行链路子帧处发送指示半静态调度（SPS）的物理下行链路共享信道（PDSCH）或物理下行链路控制信道（PDCCH）具有特定子帧配置的下行链路导频时隙（DwPTS），其中eNB不发送PDSCH，并且UE在DwPTS中不处于SPS活动模式; 以及当MBSFN子帧中的UE不处于SPS活动模式时，通过单频网络（MBSFN）子帧进行多媒体广播。

摘要： Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.
