摘要： A high-power point (110) and one or more low-power points (120) transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).

摘要： A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords (122) to be transmitted during a subframe and calculating, for each of M control signals to be transmitted during the subframe, a value (Q') based at least in part, on the number of bits in the one or more user data codewords (122), and an estimated number of user data vector symbols (124) onto which the one or more user data codewords (122) will be mapped. The estimate of the number of user data vector symbols (124) for a particular one of the M control signals depends, at least in part, on a number of control vector symbols (124) to be allocated to one or more others of the M control signals. The method also includes determining a number of control vector symbols (124) onto which to map each of the M control signals based on a respective value Q' calculated for that control signal, mapping the control signals for that control signal, and transmitting the control vector symbols.

摘要： Downlink control information (DCI) extensions to support 3GPP Rel-10 functionalities comprise minimal extensions of DCI format 2B. In some embodiments, only two extra bits (20) are introduced to signal rank up to eight, by reusing the Scrambling Identity bit (16) while at the same time supporting different MU-MIMO dimensioning for the important cases of rank-1 and rank-2. This new DCI format can potentially support not only single cell downlink transmission but also some other Rel-10 functionalities, e.g. CoMP or relaying/HetNet.
摘要翻译：用于支持3GPP Rel-10功能的下行链路控制信息（DCI）扩展包括DCI格式2B的最小扩展。在一些实施例中，通过重新使用加扰标识位（16），同时支持秩-1和重要情况的不同的MU-MIMO尺寸标注，仅引入两个额外的比特（20）来信号等级达到八个 -2。这种新的DCI格式不仅可以支持单小区下行链路传输，还可以支持一些其他Rel-10功能，例如， CoMP或中继/ HetNet。

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 Λ/ τ /2, where NT 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 Λ/ τ /2 antenna elements and with co-polarized arrays of Λ/ τ antenna elements.

摘要： One aspect of the teachings presented herein provides advantages for sending precoder selection feedback (44) from a transceiver (12) to another transceiver (10), for use by the other transceiver (10) as precoding recommendations. The transceiver (12) generates two types of precoder selection feedback (44), where one type uses a smaller signaling payload than the other and therefore provides a distinct reduction in the signaling overhead associated with reporting precoding recommendations. The transceiver (12) uses the reduced-overhead type of reporting when reporting at certain times, or on certain channels, or in response to control signaling (48). In one example, a UE (86) in an LTE network (80) sends precoder information to an eNodeB (84) on the PUCCH by sending smaller-range index values (56) that index only a subset (54) of precoders (28), but sends full-range index values (52) when reporting on the PUSCH, which index a larger set (50) of precoders (28).
摘要翻译：本文给出的教导的一个方面提供了用于将预编码器选择反馈（44）从收发器（12）发送到另一个收发器（10）的优点，供其他收发器（10）用作预编码建议。收发器（12）产生两种类型的预编码器选择反馈（44），其中一种类型使用比另一种更小的信令有效载荷，因此提供与报告预编码建议相关联的信令开销的明显减少。收发器（12）在某些时间或某些信道上或响应于控制信令（48）报告时使用降低开销类型的报告。在一个示例中，LTE网络（80）中的UE（86）通过发送仅索引预编码器（28）的子集（54）的较小范围索引值（56）向PUCCH上的eNodeB（84）发送预编码器信息），但是当在PUSCH上报告时，发送全范围索引值（52），其对较大的预编码器集合（50）进行索引。

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.
