摘要： The present invention uses user-specific resources, as allocated on the uplink, for conveying one or more antenna-specific sounding reference signals (SRSs). This technique advantageously permits, for example, a user equipment (UE) configured for uplink Multiple-Input-Multiple-Output (MIMO) operation to send antenna-specific SRSs within the granted resources allocated to the UE via one or more scheduled uplink grants. That is, within the granted resources allocated by a given uplink grant, a UE uses at least a portion of those resources for sending antenna-specific SRSs, rather than for sending uplink data (user traffic). Thus, in one or more embodiments, the present invention comprises a method at a UE of transmitting antenna-specific SRSs for two or more uplink transmit antennas. The method comprises transmitting an antenna-specific sounding reference signal for at least one of the uplink transmit antennas within a granted resource allocated to the user equipment for a scheduled uplink data transmission.
摘要翻译：本发明使用在上行链路上分配的用户特定资源来传送一个或多个天线特定的探测参考信号（SRS）。该技术有利地允许例如配置用于上行链路多输入多输出（MIMO）操作的用户设备（UE），以经由一个或多个调度的上行链路授权在分配给UE的授权资源内发送天线专用SRS。也就是说，在由给定的上行链路授权分配的授权资源内，UE使用这些资源的至少一部分来发送天线特定的SRS，而不是用于发送上行链路数据（用户业务）。因此，在一个或多个实施例中，本发明包括在UE处发射用于两个或更多个上行链路发射天线的天线专用SRS的方法。所述方法包括在分配给所述用户设备的授权资源中为所调度的上行链路数据传输发送用于所述上行链路发射天线中的至少一个的天线专用探测参考信号。

摘要： A method of selecting at least one communication link in a wireless communication network is proposed, comprising the steps of transmitting from at least one transmitting node in the network a pilot signal from each of at least two transmitter antennas of the transmitting node, receiving the pilot signals from the at least two transmitter antennas in a receiving terminal, estimating, in the terminal, a covariance matrix of the channel, based on the pilot signals received, determining the pathloss for each antenna based on the covariance matrix, selecting one of at least two possible links for the communication between the terminal and the transmitting nodes. The terminal is enabled to measure on each transmitter antenna individually, which provides a better tool for link selection and cell selection.

摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (20) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.
摘要翻译：根据本发明，电信网络（20）的接收节点（例如，上行链路中的无线电基站（20）或下行链路中的移动终端（24））向发送节点（例如，关于在发送节点和接收节点之间的多个频率聚合载波（分量载波）（10）上接收的信号，上行链路中的移动终端（24）或下行链路中的无线电基站（22）。如果所有信号在接收节点中被正确地解码，则肯定确认消息（ACK）被发送到发送节点; 如果不是全部信号被正确地解码，则发送否定确认消息（NACK），或者不发送确认消息。以这种方式，可以针对在多个载波上接收的信号发送单个确认消息。确认消息可以具有与传统标准相同的格式（例如，如3GPP规范的版本8中所规定），提供与现有设备的兼容性。与每个分量载波发送各个确认消息的简单方法相比，消息的数量也减少了。

摘要： The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

摘要： Method and arrangements for scheduling transmission resources in a first node in a cell comprised within a wireless communication network. The first node is arranged to communicate over a communication channel with at least one user equipment within the cell. The communication is made by using a frame comprising uplink resources and downlink resources with a switching point between the downlink resources and the uplink resources. The method comprises the step of obtaining a parameter referring to the expected transmission quality of the communication and/or the expected coherence properties of the communication channel. The method also comprises scheduling a transmission on an uplink or downlink resource. The resource is located on a time distance from the switching point. The time distance is based on the obtained parameter.

摘要： Method and apparatus in a communication unit (400) employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received RX sub-frames, in TX sub-frames available for transmission. An obtaining unit (402) in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit (404) in the communication unit then schedules feedback reports (FR) in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.
