摘要： An approach for providing interference measurements for device-to-device communication is disclosed. A logic generates a control signal to instruct a plurality of stations to perform measurement relating to interference or path loss by the stations. The logic then receives measurement information from the stations and determines, based on the measurement information, whether resources are to be scheduled to provide direct communication between two of the stations.

摘要： A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.

摘要： An aspect of this invention is a definition of a set of reused channel state information reference signal (CSI-RS) resources among transmission points, which can be lower power nodes, for intra-cell coordinated multi-point (CoMP) operation. Separate CSI-RS resources are defined for each transmission point for sporadic separate measurements to be made by user equipment. The sporadic measurements may be implemented with low additional overhead, and are used for generating potentially simplified CSI feedback to an evolved NodeB that enables adapting shared channel reuse and also potentially making related channel quality indicator (CQI) compensation.
摘要翻译：本发明的一个方面是用于小区内协调多点（CoMP）操作的传输点之间的一组重用信道状态信息参考信号（CSI-RS）资源的定义，其可以是较低功率节点。为每个传输点定义单独的CSI-RS资源，用于由用户设备进行的零星分离测量。零散测量可以用低附加开销来实现，并且用于向演进的节点B生成潜在的简化的CSI反馈，这使得能够适应共享信道重用并且还潜在地产生相关的信道质量指示符（CQI）补偿。

摘要： A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.

摘要： Pilot sequences (for aiding a receiver in estimating a channel) are disposed in a frame structure that has subframes of sub-carriers and symbol positions. Locations of common pilot sequences are predetermined, and includes 1) in each subframe, a pilot sequence is disposed in a first symbol position for each of at least two staggered sub-carriers, and 2) in at least one subframe, at least one pilot sequence is disposed in other than the first symbol position and in a sub-carrier other than any of the at least two staggered sub-carriers. Dedicated pilot sequences, whose locations in the frame are not predetermined, are disposed in response to an indication of channel quality received over a wireless link. Common pilot sequences may relate to one or two transmit antennas, and dedicated pilot sequences may enable addition of third and fourth transmit antennas.
