摘要： A PDSCH resource element mapping method is used for joint transmissions. The method solves a problem of colliding resource elements in joint transmissions, due to interference caused when PDSCH resource elements are transmitted in the resource block of one cell and cell-specific reference signals (CRSs) are transmitted in the same location of the resource block of an adjacent cell. The method is particularly beneficial for coordinated multipoint (CoMP) transmissions. The PDSCH resource element mapping method employs one of three schemes for transmitting the collided resource elements, with minimal interference. In the first scheme, one PDSCH symbol is transmitted over three consecutive CRS-collided PDSCH resource elements. In the second scheme, two PDSCH symbols are transmitted over three consecutive CRS-collided PDSCH resource elements. In a third scheme, CRS-collided resource elements are transmitted using a lower modulation order than is specified by the modulation and coding scheme.
摘要翻译：用于联合传输的PDSCH资源元素映射方法。该方法解决了由于在一个小区的资源块中发送PDSCH资源元素时引起的干扰，在联合传输中冲突资源元素的问题，并且在资源块的相同位置发送小区特定参考信号（CRS）相邻单元格。该方法对协同多点（CoMP）传输特别有利。 PDSCH资源元素映射方法采用三种方案之一，以最小的干扰来发送冲突的资源元素。在第一方案中，通过三个连续的CRS冲突的PDSCH资源元素发送一个PDSCH符号。在第二方案中，通过三个连续的CRS冲突的PDSCH资源元素发送两个PDSCH符号。在第三方案中，CRS冲突的资源元素使用比由调制和编码方案指定的更低的调制阶数来发送。

摘要： Technology is discussed for increasing the spectral efficiency of an Orthogonal Frequency-Division Multiplexing (OFDM) symbol. Spectral efficiency can be increased by adding information to a band edge of the OFDM symbol in connection with measures taken to reduce OOB spectral leakage from the OFDM symbol. Spectral leakage reduction measures can include application of a tapering window to at least a portion of OFDM data in the time domain to reduce power in side-lobes in the frequency domain. In some examples, such measures can comprise reducing transmission power at certain frequencies for a set of adjacent sub-carriers within the OFDM symbol at or near the band edge of the OFDM symbol. The additional bandwidth at the OFDM symbol can be used for many different applications, such as, without limitation, Device-to-Device (D2D) communication and/or Machine-to-Machine (M2M) communication.
