摘要： International Mobile Telecommunications (IMT) Advanced technology, also known as 4th Generation (4G) targets to support up to 100 MHz BW. LTE currently supports single carrier bandwidths of up to 20 MHz. The present application describes a multi-carrier approach in which some embodiments of the invention provide a simple solution of aggregating multiple single carrier bandwidths to obtain a wider bandwidth (>20 MHz). Such an approach may extend Long Term Evolution (LTE) bandwidth to greater than that provided by a single carrier, yet maintain full backward compatibility with technologies that predate 4G technology and utilize smaller, single carrier bandwidths. More generally, embodiments of the invention can apply to other communication standards than only LTE.

摘要： Methods and apparatus are described for enabling downlink transparent relay in a wireless communication network. In a wireless communications network, a base station and a mobile station may communicate with each other via a relay station, as needed. Transparent relay may allow for relay communication between a base station and a mobile station although the mobile station is unaware of the relay station. However, non-contiguous transmission of a relay station may lead to channel quality measurement and channel estimation degradation during downlink transparent relay. According to some aspects, a base station may schedule a mobile station to a transmission mode that utilizes dedicated pilot signals for downlink transparent relay, and a relay station may transmit data and dedicated pilot signals over the same channel resources as the base station. According to some aspects, the relay station may null common pilot signals transmitted by the base station.
摘要翻译： 描述了用于在无线通信网络中启用下行链路透明中继的方法和装置。 在无线通信网络中，基站和移动台可以根据需要经由中继站进行通信。 尽管移动台不知道中继站，但是透明中继可以允许基站和移动台之间的中继通信。 然而，中继站的不连续传输可能导致下行链路透明中继期间的信道质量测量和信道估计恶化。 根据一些方面，基站可以将移动台调度为利用用于下行链路透明中继的专用导频信号的传输模式，并且中继站可以通过与基站相同的信道资源发送数据和专用导频信号。 根据一些方面，中继站可以丢弃由基站发送的公共导频信号。
