摘要： Methods and apparatuses for enabling frequency selective repetition of signals in a telecommunication system in which aggregation of component carriers is applied. Information signals are received 1102 in a first set of frequency bands, which is defined to cover anchor carriers, which can be used by both legacy and non-legacy terminals. Further, information is received 1104 in a second set of frequency bands, which is defined to cover non-anchor carriers, which only can be used by non-legacy terminals. Instructions concerning which frequency band(s) that should be repeated by the repeater node, are also received 1106. Thereafter, the frequency bands indicated in the instructions are filtered out 1110, after which these frequency bands or parts are repeated by the repeater node. This results in enabling frequency selective repetition in a system which may comprise legacy mobile, which limits the interference in the system, which enables higher bitrates and saves energy.

摘要： In a cellular, broadband radio access network, such as a High Performance Local Area Network Type 2 (HIPERLAN/2), which employs multiple antennas per base station, the process of identifying and selecting the most appropriate base station antenna to support a given mobile terminal may be accomplished more effectively by allowing the mobile terminal to initiate antenna selection and, thereafter, to identify the most appropriate one of the multiple base station antennas. By utilizing the mobile terminal in this capacity, the process of antenna selection can be accomplished more effectively even if there is relatively little uplink communication between the mobile terminal and its corresponding base station.

摘要： In a wireless telecommunications network, transporting identification information, such as access point identifier (AP ID) and wireless terminal identifier (WT ID) information, in each uplink and each downlink protocol data unit (PDU) being transmitted between a sender and a receiver, without increasing bandwidth requirements. This is accomplished by modifying each PDU as a function of a first identification vector, prior to transmission, wherein the first identification vector reflects, for example, the AP ID and the corresponding WT ID. At the receiver, the PDU is re-modified as a function of a second identification vector, wherein the second identification vector reflects an expected AP ID and WT ID. If the receiver is the intended recipient of the PDU, the first and second identification vectors will be the same, and the process of re-modifying the PDU merely serves to restore the original value of the PDU. The receiver can detect whether the original value of the PDU has been restored through a data integrity check, for example, one which employs a cyclic redundancy code (CRC). The result can then be used to determine whether the receiver is, in fact, the intended receiver, and whether the receiver should decode the PDU or discard it.

摘要： The present invention relates to methods and arrangements in a wireless communication system supporting cyclic-prefix insertion, using a symbol sequence comprising a number of samples for transmission over a radio channel that enables the handling of very large signal delay spreads. The symbol sequence is built up by a first symbol with CP and a second symbol with CP. The second symbol is a copy of the first symbol with the samples shifted in a way that makes the two adjacent symbols with CP match in regards to the sample order. The symbol sequence may also comprise a third symbol with CP or more, where the third symbol is a copy of the second symbol and with the samples shifted in analogy with the symbol shift described above. The resulting symbol sequence will thus appear as an extended continuous symbol thanks to the precise cyclic shift that matches adjacent symbols. This allows the receiver to place its FFT window anywhere during the extended symbol, e.g. at the end of the symbol sequence thus making it possible to handle a delay spread longer than the CP duration. It also allows to place e.g. two FFT windows and to combine the extracted signal into one SNR improved signal, while still handling a longer delay spread.
摘要翻译：本发明涉及支持循环前缀插入的无线通信系统中的方法和装置，其使用包括用于在无线电信道上传输的多个样本的符号序列，其使得能够处理非常大的信号延迟扩展。符号序列由CP的第一个符号和CP的第二个符号组成。第二个符号是第一个符号的副本，样本的移动方式使得两个相邻符号与CP相对于样本顺序匹配。符号序列还可以包括具有CP或更多CP的第三符号，其中第三符号是第二符号的副本并且样本与上述符号移位类似地移位。由于与相邻符号匹配的精确循环移位，所得到的符号序列因此将显示为扩展的连续符号。这允许接收机在扩展符号期间的任何位置放置它的FFT窗口，例如，在符号序列的末尾，从而可以处理比CP持续时间更长的延迟扩展。它还允许放置例如两个FFT窗口并且将提取的信号组合成一个SNR改善的信号，同时仍然处理较长的延迟扩展。

摘要： The present application discloses systems and methods for reducing output-to- input feedback signal interference caused by a forwarding node that is configured to forward information received from a transmitter. In some embodiments, this output-to- input feedback signal interference is compensated for by the transmitter. For example, the transmitter is configured such that the signal that is transmitted by transmitter to the forwarding node includes both (1) a primary signal or 'desired' signal (e.g., the signal that is intended for a receiving device) and (2) a filtered version of the primary signal. The filter that produces the filtered version of the primary signal is configured (e.g., the filter's filter weights are adapted) such that the filtered version of the primary signal cancels or reduces the undesired output-to-input feedback signal.

摘要： For uplink cooperation of a serving access node (100-1) one or more supporting access nodes (100-2) are selected. The selection is based on a characteristic of a link between a terminal (200) served by the serving access node (100-1) and the supporting access node (100-2), or is based on a characteristic of a link between a further terminal (200′) served by the supporting access node (100-2) and the serving access node (100-1). The characteristics of the links may comprise a signal quality, e.g. a path gain, a signal strength, or a latency. The characteristics of the links may also comprise scheduling information, e.g. time resources and/or frequency resources used on the link.

摘要： Network coding may be performed with encoding and/or decoding that involves a multiplication operation. In an example embodiment, a communication node is adapted to perform multiplicative network coding. The communication node includes an encoder and a decoder. The encoder is arranged to perform an encoding operation by multiplying two or more signals that bear information to form a composite signal. The decoder is arranged to perform a decoding operation by multiplying a received composite signal with one or more complex-conjugated signals, with the decoder yielding a decoded signal that bears information. With the encoding operation, the communication node is adapted to at least partially perform multiplicative-network-coding encoding for a sending communication mode. With the decoding operation, the communication node is adapted to at least partially perform multiplicative-network-coding decoding for a receiving communication mode.

摘要： In order to transmit a data message in a multi-hop environment, a first station broadcasts or multicasts a transmission to other stations or receivers nearby. After one or more of the stations replies to the first station, the first station selects one of the stations that replied and transmits a command message to the selected station to assume responsibility for forwarding the data message. The data message can accompany the first transmission from the first station, or can accompany the command message. In addition, the replies to the first station can include information regarding costs of routing the data message to its destination. In another variation, the first transmission can include both the data message and a command message designating one of the nearby stations, so that when the designated station receives the first transmission it can immediately forward the data message and then later reply to the first station. This variation also includes a backup mechanism so that if the designated station does not receive the first transmission, one or more of the other nearby stations that did receive the first transmission can reply to the first station, which can then evaluate the replies, select one of the stations that replied, and transmit a command message to the selected station.
