摘要： In a method for receiving control information, a transceiver decodes at least one set of decoding candidates, and then detects whether control information is present on the control channel based on the decoded at least one set of decoding candidates. In a method for transmitting control information, a transceiver selects a decoding candidate from a set of decoding candidates for transmitting control information on a control channel; and transmits to another transceiver, control information using at least one time-frequency control channel resource element corresponding to the selected decoding candidate.

摘要： A packet data transmission system comprises primary stations (PS) having signal transmitting and receiving means and antennas (PA1 to PA4) for propagating downlink signals and receiving uplink signals and a plurality of secondary stations (SS) able to roam within the coverage areas of the primary stations. Each secondary station (SS1) has signal transmitting and receiving means, a predetermined number of antennas (SA1 to SA4), and means for monitoring its radio environment. Information about the radio environment is relayed as an uplink signal to the respective primary station which modifies its mode of transmission of packet data signals. The secondary station in response to the modified mode of transmission of the downlink signals adapts its receiver resources to process the packet data signals and effect cancellation of any interference.

摘要： A radio communication system comprises a communication channel for the transmission of data packets (302) from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement (304) or a negative acknowledgement (306)) to the primary station for each of the plurality of packets. The signaling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.

摘要： The invention provides a method for efficiently defining E-RACH resources at least partly with reference to R99 RACH resources. This is achieved such that very little additional signaling is required on the BCH. E-RACH resources may be efficiently defined by signaled or predetermined differences from the R99 RACH resources. Resources for each PRACH are broadcast using the BCH. However, some UEs are configured to use E-RACH, for example by means of higher-layer signaling. In one embodiment, the resources available for each E-RACH for the configured UEs are given by the same set of signatures but the scrambling code and sub-channels are different. In another embodiment, the resources available for each E-RACH for the configured UEs are given by the same set of scrambling codes, but the signatures and sub-channels are different. In a typical, but not exclusive embodiment, the invention is applied in UMTS WCDMA.
摘要翻译：本发明提供了一种用于至少部分地参考R99RACH资源有效地定义E-RACH资源的方法。实现这一点，使得在BCH上需要非常少的附加信令。可以通过与R99RACH资源的信号或预定的差异有效地定义E-RACH资源。使用BCH广播每个PRACH的资源。然而，一些UE被配置为使用E-RACH，例如通过更高层的信令。在一个实施例中，针对配置的UE的每个E-RACH可用的资源由同一组签名给出，但是扰码和子信道是不同的。在另一实施例中，用于配置的UE的每个E-RACH可用的资源由同一组扰码给出，但是签名和子信道是不同的。在一个典型但非排他性的实施例中，本发明应用于UMTS WCDMA。

摘要： A method for transmission of control information from a primary station to at least one secondary station, includes transmitting with a first set of control information parameters control information corresponding to data transmission with a first set of data parameters, and transmitting with a second set of control information parameters control information corresponding to data transmission with a second set of data parameters. At least one control information parameter has a difference in value between the two sets of control information parameters, where the difference in value has a dependency on the difference between the value of a data parameter in the first set of data parameters and the value of the data parameter in the second set of data parameters. The data parameter is a different parameter from the at least one control information parameter.

摘要： A communication system includes a downlink indicator channel for the transmission of an indicator signal indicating that a data packet is scheduled to be transmitted on a downlink data channel from a primary station to a secondary station. In response to detection of the indicator signal, the secondary station transmits a status signal, for example a negative acknowledgement signal, on an uplink channel to the primary station immediately before transmission of a positive or negative acknowledgement signal to indicate the status of the received data packet. By providing the primary station with two chances to detect the case where the secondary station fails to detect the indicator signal, peak power requirements of the uplink channel can be reduced, thereby reducing system interference levels.

摘要： A secondary station has a receiver capable of resolving signals received as a plurality of multipath signals from a plurality of base stations during a soft handover process. This capability may, for example, be provided by a Rake receiver. In order to decode and act upon the received signals in a very short period of time, signals arriving after a predetermined time are not processed by the receiver which is able instead to process weaker signals which arrived before the time. Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification. The predetermined time may be the time after which signals are received too late for use in determining the next power control change.
摘要翻译：次级站具有能够在软切换过程期间从多个基站解析作为多个多路径信号接收的信号的接收机。该功能可以例如由Rake接收机提供。为了在非常短的时间段内对接收的信号进行解码和动作，在预定时间之后到达的信号不被接收机处理，接收机可以代替处理在时间之前到达的较弱的信号。这样的次站特别适合于对UMTS系统中的接收信号中包括的功率控制命令进行解码和作用，UMTS系统提供非常有限的时间段。预定时间可以是接收太迟的信号以用于确定下一个功率控制变化的时间。
