摘要： Multipath components of transmitted data symbols are received with individual delays and processed by a RAKE having a number of fingers. A delay profile (31 ) indicating magnitudes for a first number of delay values is provided. Estimated magnitudes for a second number of delay values located between the first number of delay values are calculated by interpolation, and a combined delay profile (32) is provided by combining the magnitudes for the first and second number of delay values. Delay values for peaks in the combined delay profile are determined, and a number of peak delay values (P 1 , P 2 , P) comprising the largest peak are selected from the combined delay profile. At least some of the selected peak delay values are provided to the RAKE and assigned to the fingers. This allows a reduction of current consumption and dye area, while still providing delay values with sufficient resolution for the RAKE.

摘要： In third generation mobile communications networks, e.g. CDMA systems, a mobile station intending to access a base station transmits a request for access to a base station and waits for a response in the form of an indicator signal. Both detecting a signal as an acknowledgement message without one being sent from the base station and failing to detect such an acknowledgement message can give rise to noise and interference in the whole cell. The invention provides a method and a user equipment for determining the received signal strength in an access slot in a downlink channel and for asserting whether detection of an indicator signal from the base station in the access slot in the downlink channel is reliable. Hereby, a more secure reception of indicator signals can be obtained, which leads to reduced interference and noise in the whole cell.
摘要翻译：在第三代移动通信网络中，例如， CDMA系统，旨在接入基站的移动台发送对基站的接入请求，并以指示符信号的形式等待响应。检测到信号作为确认消息而没有从基站发送并且未能检测到这样的确认消息可能会在整个小区中产生噪声和干扰。本发明提供一种用于确定下行链路信道中的接入时隙中的接收信号强度的方法和用户设备，并且用于断言来自下行链路信道中的接入时隙中的来自基站的指示符信号的检测是否可靠。因此，可以获得更安全的指示符信号的接收，这导致整个小区中的干扰和噪声的降低。
