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 a number of control vector symbols (124) to allocate to control information during the subframe. The number of control vector symbols (124) is calculated based at feast in part on the number of bits in the one or more user data codewords ( 122) to be transmitted during the subframe and an estimate of the number of vector symbols (124) onto which the one or more user data codewords (122) will be mapped. The estimate of the number of vector symbols (124) depends, at least in part, on the number of control vector symbols (124) to be allocated to control, information. The method also includes mapping one or more control codewords (120) to the calculated number of control vector symbols (124) and transmitting the user data vector symbols (124) and the control vector symbols (124) over a plurality of transmission layers during the subframe.

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 (12), so that precoder selections made by the remote receiver (12) are restricted to permitted subsets (50) of overall precoders (28) within a defined set (26) of overall precoders (28), or to permitted subsets (84) within larger sets (80, 86) of conversion precoders (74) and tuning precoders (76), for the case where the overall precoders (28) are represented in factorized form by conversion and tuning precoders (74, 76). 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：本文的教导的一个方面涉及信令码本限制，以限制从远程收发器（12）反馈的预编码器建议，使得由远程接收器（12）进行的预编码器选择被限制为整体的允许子集（50）在整个预编码器（28）的限定集合（26）内的预编码器（28）或转换预编码器（74）和调谐预编码器（76）的更大组（80,86）内的允许子集（84）整个预编码器（28）由转换和调谐预编码器（74,76）以分解形式表示。作为非限制性示例，这些教导有利地提供LTE或LTE-Advanced网络中的预编码器限制，其中正在进行的开发旨在使用更大，更丰富的预编码器集合，并且其中所公开的用于确定，发信号和响应子集的机制限制提供了显着的操作优势。

摘要： A receiving unit or a transmitting unit of a wireless network for facilitating noise and interference measurements on an air interface. The receiving unit includes a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid. The receiving unit includes an electronic memory having code in communication with the network interface which stores the information. The receiving unit includes a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel. In the transmitting unit, the processing unit takes the presence of a silent RE grid into account in the transmission of a control or a data channel. A method in the receiving unit or a transmitting unit of a wireless network, for facilitating noise and interference measurements on an air interface. The method includes the steps of obtaining information relating to a time-varying layout of a silent resource element (RE) grid. There is the step of taking a presence of a silent RE grid into account in the reception of a control or a data channel.
