摘要： A radio communication system has a plurality of transmission formats available for transmitting data signals, and a pilot signal is transmitted during the transmission of data to enable channel estimation. The transmit power of the pilot signal is varied depending on the current transmission format of the data, and is reduced in the periods between data transmissions.

摘要： When a radio station terminates a first service on a first radio frequency channel and selects a second radio frequency channel for engaging in a second service, a time delay is inserted after the termination of the first service and before selecting the second radio frequency channel or before engaging in the second service. The time delay is dependent on the state of the radio station and/or a characteristic of the second service.

摘要： A receiver (13) of user equipment, UE, (10) of a Universal Mobile Telecommunications System, UMTS, network receives a digitally encoded radio signal over a downlink (11) from a base station (12). A Digital Signal Processor, DSP, (14) of the UE (10) estimates BER of data bits of power control commands received in the signal during an out of synchronisation procedure. More specifically, the DSP (14) samples the amplitude with which the data bits are received and determines a ratio of functions of one or more moments of the sampled amplitudes. The DSP (14) then compares the determined ratio to one or more values of BER for different ratios in a look-up table to estimate BER.

摘要： A communication system comprises a downlink data channel for the transmission of data packets from a primary station to a secondary station and uplink and downlink control channels. The secondary station measures one or more characteristics of the data channel and issues a report to the primary station, which determines an operational parameter of the data channel in response to the report. The secondary station determines average channel characteristics over a measurement period. The length of the measurement period may be signalled by the primary station or determined directly by the secondary station. In one embodiment the selected period depends on the speed (V) of the secondary station. This is determined (604) by either station and tested to determine (606) whether it is outside the range for the current measurement period: if it is the period is reset (608).

摘要： A method and apparatus for transferring information over a communications link includes transmitting information at a first power level, monitoring for correct reception of the transmitted information and transmitting further information at a second, power level other than that used for the original transmission if correct reception did not occur. The further information allows the content of the originally transmitted information to be established and in one embodiment constitutes a retransmission of the originally transmitted information. By retransmitting at a different power level the probability of correct reception may be enhanced, especially when the communications link is wireless. The first and second transmission power levels are governed using closed loop power control such that transmission power level is controlled to achieve a required quality of reception parameter at the receiving end of the link. In one arrangement the quality or reception parameter is the signal-to-interference ratio.

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： 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。
