摘要： A communication device includes a donor receiver that receives a first beam of input radio frequency (RF) signals from a base station or a network node. The communication device further includes a service transmitter that transmits a second beam of RF signals in a first radiation pattern to a user equipment (UE). The communication device further includes control circuitry that detects an amount and a direction of echo signals at the donor receiver. The control circuitry applies polarization to the second beam of RF signals transmitted to the UE and calibrates the polarization to minimize the echo signals at the donor receiver. A second radiation pattern is generated for the second beam of RF signals and communicated to the UE based on the calibrated polarization. The communication of the second beam of RF signals in the generated second radiation pattern further reduces the echo signals at the donor receiver.

摘要： Embodiments provide a method for reducing a self-interference signal in a communications system, and an apparatus. The method includes: sending a sounding signal; receiving an echo signal, where the echo signal includes a near-field reflected signal corresponding to the sounding signal. The method also includes separating the near-field reflected signal corresponding to the sounding signal from the echo signal, and determining a near-field reflection channel parameter according to the near-field reflected signal. The method also includes determining a reconstructed near-field reflected self-interference signal based on the near-field reflection channel parameter, and subtracting the reconstructed near-field reflected self-interference signal from a received second communication signal.

摘要： Embodiments of this invention describe a method to reduce the effective inter carrier spacing between the sub-carriers of wireless, wired or optical transmissions and thereby increase the spectral efficiency of the communication system. Signal transmitted from multiple transmit chains are shifted in frequency at the transmitter. At the receiver a plurality of receive chains is used, the received signals are similarly shifted in frequency and used to reduce the inter carrier interference. Embodiments also describe a method for Full Duplex communication where the transmitters transmit using different frequency shifts. The receiver receives the transmitted signal and an echo of it's transmission. As the received transmission is shifted in frequency from it's transmission, it can cancel out the echo and receive the intended signal.

摘要： An apparatus in a mobile communication system for providing a multimedia broadcast/multicast service (MBMS) and a method for giving notification of an MBMS service while considering transmission mode are provided. A controlling radio network controller (CRNC) sends, to a serving radio network controller (SRNC), transmission mode information indicating point-to-point (PTP), point-to-multipoint (PTM), or “Not provide” cell by cell. The SRNC determines service notification on the basis of the transmission mode information. The CRNC minimizes a signaling load on an Iur interface when sending, to the SRNC, the transmission mode information suitable for each cell.

摘要： An echo canceller used in a vocal information exchange system operates in such a circumstance that a sound wave released by a speaker is picked up by a microphone unintentionally and works to suppress an echo signal included in the audio signal produced by the microphone by using a pseudo echo signal which is produced based on the incoming audio signal to be fed to the speaker and produce a subtracted audio signal which becomes the outgoing audio signal, with the echo signal being suppressed based on the accurately-calculated degree of echo suppression achieved by use of the pseudo echo signal.

摘要： The present invention relates to broadcast and/or multicast services in mobile communication networks. Control (105) and user (107′, 107″) planes for services directed to a user (50A-C) in a multicast group (60) are allowed to be separated from each other. At least two user equipments (50A-C) (belonging to the same multicast group) receives service data over a common user plane (107′) over an Iu interface (17) In cases where user equipment (50C) is controlled by a SRNC (22B) different from the CRNC (22A), a radio network subsystem application protocol is extended by procedures communicating service information from the SRNC (22B) to the CRNC (22A). The control plane (105) of such a user equipment (50C) can thus have a separate path compared with a common user plane (107′). Preferably, the user plane (107′) is arranged directly over the Iu interface (17) between a serving support node (12) and the CRNC (22A), while control planes (105) may have a path over the Iur interface (14).
摘要翻译：本发明涉及移动通信网络中的广播和/或多播服务。允许针对多播组（60）中的用户（50A-C）的服务的控制（105）和用户（107'，107“）平面彼此分离。属于相同组播组的至少两个用户设备（50AC）通过Iu接口（17）在公共用户平面（107'）上接收业务数据。在用户设备（50C）由SRNC （22B），不同于CRNC（22A）的无线电网络子系统应用协议通过将服务信息从SRNC（22B）传送到CRNC（22A）的过程被扩展。因此，这样的用户设备（50C）的控制平面（105）可以与普通用户平面（107'）相比具有单独的路径。优选地，用户平面（107'）直接布置在服务支持节点（12）和CRNC（22A）之间的Iu接口（17）上方，而控制平面（105）可以具有在Iur接口 14）。
