摘要： A wireless communication system (14) comprises points that have time division duplex, TDD, configurations. Information is obtained indicating the TDD configuration of each of multiple points to which a particular wireless communication device (6) is simultaneously connected. Based on this obtained information, it is determined that one or more time-domain radio resources used by the multiple points are conflicting resources defined by the TDD configuration of one or more of the multiple points as being uplink resources and defined by the TDD configuration of one or more others of the multiple points as being downlink resources. For the device (6), each of the one or more conflicting resources are resolved as either an uplink resource to be used by the device (6), a downlink resource to be used by the device (6), or a resource not to be used by the device (6), based on one or more rules for optimizing use of conflicting resources.

摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node and a receiving node. When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： For data transmission in a wireless communication network, a radio channel divided into subframes in the time domain is used. A network system (100) assigns resource elements in a first subframe (20) and at least one subsequent subframe (21, 22) to a user equipment (200). By downlink control information transmitted in the first subframe (20), the network system (100) sends a multi-subframe assignment (503) to the user equipment (200). The multi-subframe assignment (503) indicates the assigned resource elements to the user equipment (200). In at least a part of the assigned resource elements in the first subframe (20) and at least a part of the assigned resource elements in the at least one subsequent subframe (21, 22), the network system (100) transmits precoded reference symbols (504, 06, 508) to the user equipment (200). Further, the network system (100) sends an indication (501) to the user equipment (200) that the user equipment (200) is allowed to assume that precoding of the reference symbols (504, 506, 508) is static over the first subframe (20) and the at least one subsequent subframe (20, 21). The user equipment (200) may utilize the precoded reference symbols (504, 506, 508) for channel estimation.

摘要： According to one aspect of this disclosure, the configuration of which Interference Measurement Resources, “IMRs”, a given user equipment, “UE”, should measure for Channel State Information, “CSI”, reporting is made more or less invariant to dynamic traffic variations affecting the set of Coordinated Multi-Point, “CoMP”, transmission points used for serving the UE, or to the use of dynamic blanking for those transmission points. These goals are achieved at least in part by configuring one or more of the transmission points to follow a first rule embodying a negative logic. According to the first rule, the transmission point transmits on a given IMR if it has been deemed as being not likely to transmit data at a time relevant to the IMR, and, conversely, to not transmit the IMR if it has been deemed as being likely to transmit data at a time relevant to the IMR.
摘要翻译：根据本公开的一个方面，给定用户设备“UE”的干扰测量资源“IMR”的配置应该针对信道状态信息“CSI”来测量，报告或多或少对动态业务不变影响协调多点，“CoMP”集合，用于服务于UE的传输点，或者对于这些传输点使用动态消隐的变化。这些目标至少部分地通过配置一个或多个传输点遵循体现负逻辑的第一规则来实现。根据第一规则，如果在与IMR相关的时间被认为不可能发送数据，则传输点在给定的IMR上发送，并且相反地，如果被认为是可能在与IMR相关的时间传输数据。

摘要： According to one or more aspects, the teachings herein improve user equipment (UE) Channel State Information (CSI) feedback, by letting the precoder part of a CSI feedback report comprise factorized precoder feedback. In one or more such embodiments, the factorized precoder feedback corresponds to at least two precoder matrices, including a recommended “conversion” precoder matrix and a recommended “tuning” precoder matrix. The recommended conversion precoder matrix restricts the number of channel dimensions considered by the recommended tuning precoder matrix and, in turn, the recommended tuning precoder matrix matches the recommended precoder matrix to an effective channel that is defined in part by said recommended conversion precoder matrix.

摘要： One aspect of the teachings herein relates to signaling codebook restrictions, to restrict the precoder recommendations being fed back from a remote transceiver, so that precoder selections made by the remote receiver are restricted to permitted subsets of overall precoders within a defined set of overall precoders, or to permitted subsets within larger sets of conversion precoders and tuning precoders, for the case where the overall precoders are represented in factorized form by conversion and tuning precoders. As a non-limiting example, these teachings advantageously provide for precoder restrictions in LTE or LTE-Advanced networks, where ongoing development targets the use of larger, richer sets of precoders, and where the disclosed mechanisms for determining, signaling, and responding to subset restrictions provide significant operational advantages.

摘要翻译：根据一个或多个方面，本文的教导通过使CSI反馈报告的预编码器部分包含分解预编码器反馈来改善用户设备（UE）信道状态信息（CSI）反馈。在一个或多个这样的实施例中，分解预编码器反馈对应于至少两个预编码器矩阵，包括推荐的“转换”预编码器矩阵和推荐的“调谐”预编码器矩阵。推荐的转换预编码器矩阵限制了推荐的调谐预编码器矩阵考虑的通道尺寸数量，反过来，推荐的调谐预编码器矩阵将推荐的预编码器矩阵与由所述推荐的转换预编码器矩阵部分定义的有效通道相匹配。
