Method to estimate the interference signal code power (ISCP) in a TD-CDMA system |
摘要 |
<p>A method to estimate the Interference Signal Code Power (ISCPm) in a cellular system of the TD-CDMA type, e.g.: TSM or any of the two 3GPP TDD modes: LCR TDD and HCR TDD respectively, is disclosed. The radio entity either the Mobile Station (MS) or Base Station (BS) which has to estimate the ISCPm firstly measures the Received Signal Code Power (RSCPm) by correlating the signal received from the physical channel of a selected midamble m<th> with the relevant sequence known in advance. In order to obtain the ISCPm value, the transmission power of the midamble m<th> scaled by the path-loss has to be substracted from the RSCPm. The ISCPm includes both the intra-cell and the inter-cell interferences plus AWGN noise; it is measured without the need for a spare midamble, avoiding restriction to the radio resource allocation. The intra-cell and inter-cell contributes to the ISCPm can be separated. <IMAGE></p> |
