摘要： Systems and methodologies are described herein that facilitate generation and processing of control signaling to support uplink network multiple-in-multiple-out (N-MIMO) communication in a wireless communication system. As described herein, respective network nodes associated with an uplink N-MIMO framework can generate channel state information (CSI) corresponding to an uplink channel from a designated network user to the respective nodes. Generated CSI can subsequently be communicated to an uplink anchor node for the network user in order to facilitate rate assignment, scheduling, and/or other operations with respect to the network user. As described herein, CSI generated and reported by respective cells can include channel profiles, carrier/interference profiles, estimated supported uplink rates, or the like. As additionally described herein, supplemental information such as observed interference levels, demodulation indicators, or the like can be communicated to an anchor node and utilized in rate assignment and/or scheduling.

摘要： Techniques for supporting Coordinated MultiPoint (CoMP) transmission are described. For CoMP transmission, multiple cells may simultaneously send one or more data streams to one or more UEs on the same time-frequency resources based on short-term channel feedback from at least one UE to at least two cells. In an aspect, a semi-static configuration may be used by a set of cells for CoMP transmission to a UE. The semi-static configuration may indicate resource elements available to the set of cells to send CoMP transmission to the UE. The available resource elements may be determined based on a maximum number of TDM control symbols for all cells in the set and resource elements used for cell-specific reference signals by the cells in the set. A cell in the set may send data on the available resource elements to the UE for the CoMP transmission.

摘要： Techniques for transmitting and receiving data with spatial interference mitigation in a wireless communication network are described. In one design, a cell may receive precoding information from a first user equipment (UE) communicating with the cell and spatial feedback information (SFI) from a second UE not communicating with the cell. The cell may select a precoding matrix based on the precoding information and the SFI. The precoding matrix may steer a transmission toward the first UE and away from the second UE. The cell may send a reference signal based on the precoding matrix, send a resource quality information (RQI) request to the first UE, receive RQI determined by the first UE based on the reference signal, and determine a modulation and coding scheme (MCS) based on the RQI. The cell may then send a data transmission to the first UE with the precoding matrix and in accordance with the MCS.

摘要： Techniques for synchronizing devices in a wireless network are described. In an aspect, a device determines a receive time for a base station, obtains a time offset for the base station from a network entity, and sets its transmit time based on the receive time and the time offset for the base station. The time offset compensates for the degree by which the base station is asynchronous with respect to a reference time, e.g., UTC time. In another aspect, a device determines and sends time difference information (e.g., a time offset or a TDOA measurement) for at least one base station to support synchronization of other devices. In yet another aspect, a network entity supports synchronization of devices, receives time difference information for at least one base station, and determines at least one time offset for the at least one base station based on the time difference information.

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.
摘要翻译：描述了用于支持无线通信系统中的中继站操作的技术。在一个方面，可以由基站和/或中继站发送位图以识别多个无线电帧中的至少两种类型的子帧。例如，位图可以指示位图覆盖的每个子帧是第一类型还是第二类型。 UE可以使用该位图来控制其操作。例如，UE可以针对第一类型的子帧执行信道估计或测量，并且可以跳过针对第二类型的子帧的信道估计和测量。另一方面，基站可以在没有被中继站用来传输参考信号的资源上传输数据和/或控制信息。这可以避免对来自中继站的参考信号的干扰，这可以提高与中继站通信的UE的性能。

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.

摘要： Collisions in a wireless network are detected and resolved through the use of transmissions by access points in the network. In some aspects, each access point may select a resource from a set of resources and transmit an indication of a unique identifier (e.g., a long identifier) of that access point on the selected resource. In some aspects, each access point may select a bit and append that bit to a reused identifier (e.g., a short identifier) of that access point to provide a channelization parameter that is used to channelize signals transmitted by the access point. The selection by a given access point may be based on a unique identifier assigned to that access point. The selection by a given access point may be a pseudorandom selection (e.g., based on a corresponding unique identifier). Another node (e.g., an access terminal) in the network may identify a collision based on the transmissions by the access points. In this case, the node may transmit an indication of the collision to cause one of the access points to cease transmitting. The node may then inform one colliding access point of the existence and identity of the other colliding access point to enable the access points to resolve the collision.
摘要翻译：通过使用网络中接入点的传输来检测和解决无线网络中的冲突。在一些方面，每个接入点可以从一组资源中选择一个资源，并且在所选择的资源上发送该接入点的唯一标识符（例如，长标识符）的指示。在一些方面，每个接入点可以选择一个比特并将该比特附加到该接入点的重用标识符（例如，短标识符），以提供用于对由接入点发送的信号进行信道化的信道化参数。给定接入点的选择可以基于分配给该接入点的唯一标识符。给定接入点的选择可以是伪随机选择（例如，基于对应的唯一标识符）。网络中的另一节点（例如，接入终端）可以基于接入点的传输来识别冲突。在这种情况下，节点可以发送冲突的指示，使接入点之一停止发送。然后，节点可以向一个冲突接入点通知其他冲突接入点的存在和身份，以使接入点能够解决冲突。

摘要： Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.

摘要： Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell- specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning sub frames. Resource elements within the positioning sub frame can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.
