Embodiment 1

[0099] The method for determining the space isolation zone in this embodiment can be applied in the process of frequency re-cultivation, such as figure 2 shown, including the following steps:

[0100] Step 201: Obtain MR data of the first communication system in the first area; the utilization efficiency of the spectrum resources of the first communication system is lower than the utilization efficiency of the spectrum resources of the second communication system; the first area includes the second an area and a third area; the second area is adjacent to the third area;

[0101] Here, in actual application, the first communication system may be Global System for Mobile Communication (GSM, Global System for Mobile Communication); correspondingly, the second communication system may be Long Term Evolution (LTE, Long Term Evolution) frequency division Duplex (FDD, Frequency Division Duplexing) system or Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multi...

Embodiment 2

[0159] On the basis of Embodiment 1, this embodiment describes in detail how to determine the space isolation zone.

[0160] The application scenario of this embodiment is: Figure 4 As shown, operators need to release part of the spectrum resources used by GSM for the more efficient LTE FDD system. Among them, the rhythm of vacated frequencies between GSM regions (regions 1 and 2) or the frequency bands that can be vacated for LTE FDD systems are inconsistent, so that the LTE FDD center frequency point or bandwidth of frequencies vacated between GSM regions may appear. Inconsistent. Since the base stations and terminal receivers of the GSM and LTE FDD systems have different sensitivities and transmit powers, it is necessary to set guard bands between areas in this scenario to reduce inter-system interference. The frequency of the guard band is used as Figure 5 shown.

[0161] Such as Figure 4 As shown, in an actual scenario, a guard band between the two areas can be se...

Embodiment 3

[0192] The application scenario of this embodiment is: Figure 6 As shown, operators need to vacate part of the frequency spectrum used by GSM for the more efficient WCDMA system to use. Among them, the rhythm of vacated frequencies between the regions of the GSM system (regions 1 and 2) or the frequency bands that can be vacated for the WCDMA system are inconsistent, so that the WCDMA center frequency point or bandwidth of the frequencies vacated between the regions of the GSM system may appear. Inconsistent. Since GSM and WCDMA base stations and terminal receivers have different sensitivities and transmit powers, it is necessary to set guard bands between areas in this scenario to reduce inter-system interference. The frequency of the guard band is used as Figure 7 shown.

[0193] Such as Figure 6 As shown, in an actual scenario, a guard band between the two areas can be set in area 1 or area 2 according to the available frequencies in area 1 and area 2. In this embod...

Abstract

The invention discloses a method for determining a space isolation band. The method comprises the steps of acquiring data of a measurement report (MR) of a first communication system in a first area, wherein the service efficiency of spectrum resources of the first communication system is lower than that of the spectrum resources of the second communication system; and determining a protection band cell from cells of the first area according to the MR data. The invention also simultaneously discloses a device for determining the space isolation band.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for determining a space isolation zone. Background technique [0002] With the development of wireless technology, more and more operators re-cultivate the frequencies originally occupied by systems with lower spectral efficiency, and apply them to standards with higher spectral efficiency. During this process, due to the fact that the original system is still in use, only part of the frequency can be vacated for the new system, and there are objective reasons such as different loads of the original system in different regions of Tengfeng or frequency usage conditions, etc. The use of bandwidth or inconsistent central frequency points ( figure 1 Regions 1, 2 shown). In this scenario, the same frequency band may be occupied by the new system and the original system in two regions respectively (such as figure 1 shaded area shown). To avoid co-channel in...
