Problems solved by technology

However, due to the uneven distribution of interference in the time slot, the traditional method of measuring ISCP can only obtain the ISCP of the training code position, and cannot obtain the ISCP of other positions (data segments). Therefore, the traditional method of measuring ISCP obtains The ISCP cannot correctly and objectively reflect the interference situation of the entire time slot

Embodiment Construction

[0014] Firstly, the first method for measuring the code power of the interference signal in the present invention will be described. like figure 1 shown, including:

[0015] Step S101: Determine the power of the received signal of the data segment to be measured and the power of the useful signal at the position of the training code.

[0016] The data segment to be measured can refer to the data segment to be measured in a time slot, and a plurality of data segments to be measured can be included in a time slot, and the data segment to be measured corresponds to a plurality of chips (chips), for ease of description, The data segment to be measured can also be referred to as a measurement point. The received signal power of the data segment to be measured may refer to a received signal strength indication (RSSI, Received Signal Strength Indication) of the data segment to be measured. Here, the useful signal power at the training code position may refer to the sum of received...

Abstract

The invention provides a method for measuring interference signal code power (ISCP). The method comprises the following steps: confirming the power of a receiving signal of a data segment to be measured and the power of a usable signal of a training code position to be measured; and obtaining the ISCP of the data segment to be measured according to the power of the receiving signal of the data segment to be measured and the power of the usable signal of the training code position to be measured. The invention also provides another method for measuring ISCP and two devices for measuring ISCP. The invention can obtain the ISCP of each data segment to be measured, instead of only the ISCP of the training code position. Accordingly, the methods and the devices can be utilized to obtain ISCP which is as correct as possible and objectively reflects the interference conditions of the whole time slot.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to the measurement technology of Interference Signal Code Power (ISCP, Interference Signal Code Power). Background technique [0002] With the gradual construction of the 3rd generation (3G, The Third Generation) mobile communication network, the coverage of the mobile communication network is getting wider and wider. A Time Division Duplex (TDD, Time Division Duplex) system is a typical 3G system. In a TDD system, the frequency of the transmitted signal is the same as the frequency of the received signal. Once the transmitted signal of one base station falls into the receiving time slot of another base station, it will inevitably cause interference to the other base station. At the same time, due to the coexistence of various networks, for a Time Division Synchronization Code Division Multiple Access (TD-SCDMA, Time Division Synchronization Code Division Multiple Access...
