Embodiment 1

[0350] This embodiment proposes an interference measurement method, which mainly includes:

[0351] The network side configures a demodulation interference measurement resource (DM-IMR) for the target data channel of the terminal, and indicates configuration information of the demodulation interference measurement resource to the terminal;

[0352] The terminal receives the configuration information of receiving interference measurement resources, determines the demodulation interference measurement resources corresponding to its target data channel, and uses the demodulation interference measurement resources to measure the interference received during the transmission of the target data channel.

[0353] Wherein, the position of the demodulation interference measurement resource in the frequency domain is determined according to the PRB carrying the target data channel. Preferably, the demodulation interference measurement resource is only allowed to exist in the PRB resourc...

Embodiment 2

[0458] The network side configures the demodulation interference measurement resource DM-IMR for the terminal, wherein the resource element RE configured as the demodulation interference measurement resource is the RE corresponding to the ZP-CSI-RS. Specifically, the demodulation interference measurement resource configured for the terminal by the network side consists of one or more ZP-CSI-RS resources. Figure 8(a) / 8(b) shows all REs that can be configured as ZP-CSI-RS in a subframe in the case of a conventional CP, where each sequence number represents a resource that can be configured as ZP-CSI-RS. Figure 9(a) / 9(b) shows all the RE resources that can be configured as ZP-CSI-RS in a subframe in the case of extended CP, where each sequence number represents a RE resource that can be configured as ZP-CSI-RS resource.

[0459] The network side indicates the demodulation interference measurement resource to the terminal in one of the following ways:

Embodiment 3

[0475] The network side configures the demodulation interference measurement resource DM-IMR for the terminal, wherein the resource element RE configured as the demodulation interference measurement resource is the RE corresponding to the ZP-CSI-RS. Specifically, the network side configures one or more sets of demodulation and interference measurement resources for the terminal, where each set of demodulation and interference measurement resources consists of one or more ZP-CSI-RS resources. Figure 8(a) / 8(b) shows all REs that can be configured as ZP-CSI-RS in a subframe in the case of a conventional CP, where each sequence number represents a resource that can be configured as ZP-CSI-RS. Figure 9(a) / 9(b) shows all the RE resources that can be configured as ZP-CSI-RS in a subframe in the case of extended CP, where each sequence number represents a RE resource that can be configured as ZP-CSI-RS resource.

Abstract

The present invention discloses an interference measurement method, system and related equipment. The method includes: the network side configures a demodulation interference measurement resource DM-IMR for the target data channel of the terminal, and the position of the DM-IMR in the frequency domain is based on The physical resource block PRB carrying the target data channel is determined; the network side indicates the configuration information of the DM‑IMR to the terminal, so that the terminal can perform transmission interference measurement of the target data channel. Adopting the scheme of the present invention can improve the accuracy of the target data channel transmission interference measurement, thereby helping to improve the demodulation / decoding performance of the target data channel at the receiving side, and further improving the receiving performance of the target data channel.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to an interference measurement method, system and related equipment. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) system is an important plan of the 3rd Generation Partnership Project (3GPP, 3rdGeneration Partnership Project). When the LTE system uses a conventional cyclic prefix (CP, CyclicPrefix), a time slot contains downlink symbols of 7 lengths; when the LTE system uses an extended CP, a time slot contains downlink symbols of 6 lengths. [0003] figure 1 It is a schematic diagram of a physical resource block (PRB, Physical Resource Block) of an LTE system according to related technologies. like figure 1 As shown, a resource element (RE, Resource Element) is a subcarrier in an OFDM symbol, and a downlink RB consists of 12 consecutive subcarriers and 7 consecutive (6 when extending the cyclic prefix) orthogonal frequency Division...
