摘要： A method performed by a network node of a wireless communication network is provided for communicating an enhanced Physical Downlink Control Channel, ePDCCH, to a user equipment, UE. , The method comprises transmitting (606) a configuration message to the UE. The configuration message comprises an indication of a first mapping of the ePDCCH to resource elements belonging to a first ePDCCH set, where the resource elements of the first ePDCCH set are different from resource elements used for a first type of signal. The method further comprises an indication of a second mapping of the ePDCCH to resource elements belonging to a second ePDCCH set, where the resource elements of the second ePDCCH set are different from resource elements used for a second type of signal, thereby enabling dynamically mapping ePDCCH to the resource elements of the first ePDCCH set or the second ePDCCH set. Further methods, UEs and computer programs are provided for communicating an ePDCCH between a network node and a UE.

摘要： Method performed by a network node (210) to indicate a first and a second set of antenna ports. The network node (210) indicates (803) to a wireless device (250) at least one of: a) a first indication of a first set (M′) of antenna ports for first measurements on first radio signals, the first measurements associated with periodic reporting, and b) a second indication of a second set (M) of antenna ports for second measurements on second radio signals, the second measurements associated with aperiodic reporting. The first set is different than the second set. The periodic and the aperiodic reporting are by the wireless device (250) and correspond to a same Channel State Information, CSI, process. The network node (210) also transmits (804), to the wireless device (250), the first radio signals, periodically, over the first set and the second radio signals over the second set.

摘要： The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.

摘要： The teachings herein present a method (700, 900) and apparatus (10, 12) that implement and use a factorized precoder structure that is advantageous in terms of performance and efficiency. In particular, the teachings presented herein disclose an underlying precoder structure that allows for certain codebook reuse across different transmission scenarios, including for transmission from a single Uniform Linear Array (ULA) of transmit antennas (14) and transmission from cross-polarized subgroups of such antennas (14). According to this structure, an overall precoder (36) is constructed from a conversion precoder (32) and a tuning precoder (34). The conversion precoder (32) includes antenna-subgroup precoders (38) of size N T /2, where N T represents the number of overall antenna ports (98) considered. Correspondingly, the tuning precoder (34) controls the offset of beam phases between the antenna-subgroup precoders (38), allowing the conversion precoder (32) to be used with cross-polarized arrays of N T /2 antenna elements and with co-polarized arrays of N T antenna elements.
摘要翻译：这里的教导提出了实现和使用在性能和效率方面有利的分解预编码器结构的方法和设备。特别地，本文给出的教导公开了一种潜在的预编码器结构，其允许在不同的传输情况下的某些码本重用，包括用于从发射天线的单个均匀线性阵列（ULA）进行发射以及来自这种天线的交叉极化子组的发射。根据这种结构，整个预编码器由一个转换预编码器和一个调谐预编码器构成。转换预编码器包括尺寸为NT / 2的天线子组预编码器，其中NT表示所考虑的整个天线端口的数量。相应地，调谐预编码器控制天线子组预编码器之间的波束相位的偏移，允许转换预编码器与NT / 2天线元件的交叉极化阵列以及NT个天线元件的共极化阵列一起使用。

摘要： Data is transmitted over multiple input multiple output (MIMO) channels. Plural bit streams are modulated into multiple data symbol vectors. Each vector has a transmission rank with one vector for each MIMO channel. Transmission rank is the number of elements in a data symbol vector corresponding to the number of data streams being transmitted in parallel over each MIMO channel. The multiple data symbol vectors are precoded into multiple precoded symbol vectors using a plurality of precoder cycling sets, one set for each transmission rank including multiple different precoders. The precoders in each precoder cycling set are well-separated with respect to a plurality of distance measures. The precoding includes precoding each data symbol vector of a transmission rank with a precoder belonging to the precoder cycling set of that transmission rank. The precoded symbol vectors are then transmitted over the MIMO channels.
