摘要： In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.
摘要翻译：在宏/ RRH设置中，信道状态信息参考信号（CSI-RS）和解调参考信号（DM-RS）可用于去耦合控制和数据传输。数据传输（例如，对于LTE Rel 10及其以外）可以基于CSI-RS和DM-RS，而可以经由CRS从不同的小区集合或TxP接收控制。本公开的某些方面引入了报告框架，其中可以基于CSI-RS来执行数据服务小区/ TxP的配置。在某些方面，CSI-RS组的新概念，即UE认为一组用于预编码矩阵指示符（PMI）/信道质量指示符（CQI）/秩指示符（RI）报告）的一组CSI-RS端口，可以被定义。

摘要： Techniques for receiving reference signals from multiple nodes and determining channel state information (CSI) for the nodes are disclosed. A user equipment (UE) may determine and report CSI for the multiple nodes to support data transmission to the UE. The nodes may transmit reference signals based on different configurations. The configuration for each node may indicate when, where, and how the node transmits its reference signal. The UE may determine CSI for different nodes and/or different combinations of nodes based on the reference signals transmitted by these nodes as well as an indication of which subframes to use to determine each CSI reported by the UE. The UE may report different CSIs for different subframes and may receive data transmission sent by a single node or a combination of nodes based on the reported CSIs.

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 enable serving cell selection in a wireless network with a multiple antenna repeater operable to support MIMO communications. In one example, a repeater using orthogonal frequency division multiplexing on the downlink can be equipped to receive, by one or more receive antennas, one or more signals using one or more radio frequency (RF) isolation schemes. The repeater can further be equipped to amplify and delay the one or more signals using one or more combination schemes. Moreover, the repeater can be equipped to transmit, by one or more transmit antennas, the amplified and delayed one or more signals, wherein at least one of the one or more receive antennas or the one or more transmit antennas includes two or more antennas.

摘要： Physical-Layer Cell Identifier (PCID) collisions may occur in a wireless network when two neighboring evolved Node Bs (eNBs) having different Global Cell Identifiers (GCID) select identical PCIDs. Evolved Node Bs may uniquely identify themselves by transmitting on a broadcast channel, such as a Physical Broadcast Channel (PBCH), a pattern of bits corresponding to the eNB's GCID. Individual User Equipments (UEs) may recognize the PCID collision by decoding the PBCH payload to identify different GCID-modulated payloads from two eNBs involved in the PCID collision. Alternatively, UEs may detect PCID collisions in the wireless network by monitoring Primary Synchronization Signals (PSS) and Secondary Synchronization Signals (SSS) on the PBCH for identical signals separated by a relatively large time offset. After detecting a PCID collision, the UEs may attempt by best effort to report the PCID collision, may report to a fallback eNB, or the UEs may use special resources on an uplink channel.
摘要翻译：当具有不同的全局小区标识符（GCID）的两个相邻演进节点B（eNB）选择相同的PCID时，物理层小区标识符（PCID）冲突可能发生在无线网络中。演进节点B可以通过在诸如物理广播信道（PBCH）的广播信道上发送与eNB的GCID相对应的比特模式来唯一地标识自身。个体用户设备（UE）可以通过解码PBCH有效载荷来识别来自涉及PCID冲突的两个eNB的不同GCID调制的有效载荷来识别PCID冲突。或者，UE可以通过监视PBCH上的主同步信号（PSS）和次同步信号（SSS）来检测无线网络中的PCID冲突，以用相对大的时间偏移分开的相同信号。在检测到PCID冲突之后，UE可以尽最大努力报告PCID冲突，可以向后退eNB报告，或者UE可以在上行链路信道上使用特殊资源。

摘要： Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.
