In S202, an interference measurement resource configuration and an interference measurement receiving mode configuration are obtained.

It should be noted that a selection of an interference measurement resource is generally determined by a network-side device on a zero-power measurement pilot. In order to better measure the interference measurement resources, in the present embodiment, it is default that a serving cell that is working does not send any signal, and measured signals are interference signals from other non-serving cells. Table 2 is an interference resource measurement table according to an embodiment of the present disclosure. Table 2 is shown as follows.

Therefore, it is understandable that the interference measurement resources described in the present disclosure actually corresponds to interferences of different non-working cells.

Optionally, the interference measurement resource configuration includes: an interference intensity and an interference characteristic of the interference cell. In addition, interference information generated among a plurality of interference cells may be superimposed. Therefore, the interference measurement resource configuration in the present embodiment should actually further include superimposed interference intensity and interference characteristic.

It should be noted that each interference measurement resource may flexibly correspond to different interference measurement resource configurations. For example, Table 3 is a corresponding table between the interference measurement resources and their configurations according to the present embodiment. Table 3 is shown as follows.

Optionally, the interference measurement resource configuration may be obtained from configuration signaling of the network-side device; the network-side device may pre-define some patterns for resource locations, and the corresponding interference measurement resource configurations may be determined according to the above mentioned patterns.

It should be noted that the interference measurement resource may be a periodic resource or a resource transmitted in a multi-shot manner. The interference measurement resource may also be a once-transmitted resource, which exists only in one sub-frame.

Optionally, the interference measurement receiving mode configuration includes at least one of followings: a configuration of receiving antenna, a configuration of receiving beam, a configuration of a range of receiving direction, a configuration of a polarization manner of receiving and a configuration of receiving weight.

It should be noted that it may also be the receiving weight that corresponds to the index of the receiving beam.

Optionally, the interference measurement receiving mode may be determined according to configuration signaling of a network-side device. For example, the network-side device sends a receiving mode corresponding to a receiving beam to user equipment via high-layer signaling. After receiving the receiving mode corresponding to the receiving beam in the high-layer signaling, the user equipment performs corresponding receiving according to the receiving modes of Table 6.

Specifically, when there are a plurality of interference measurement resource groups, receiving modes corresponding to the plurality of interference measurement resources are respectively determined according to configuration signaling corresponding to the plurality of interference measurement resources.

Optionally, the above-mentioned configuration signaling includes: signaling in an explicit manner and signaling in an implicit manner.

Specifically, if signaling in an explicit manner is used to perform indication, then it may be understood that corresponding receiving modes are determined according to a predetermined corresponding relationship between the interference measurement resources and the receiving modes.

Specifically, if signaling in an implicit manner is used to perform indication, then it required to find a bundling relationship or correlated signal corresponding to the receiving modes.

Optionally, an interference measurement receiving mode may be determined according to a receiving mode of a configured first type of signals.

It should be noted that the first type of signals at least includes: a downlink measurement pilot, a downlink demodulation pilot, an uplink demodulation pilot, an uplink measurement pilot and an uplink random access signal.

Optionally, a resource location of the first type of signal associated with the interference measurement receiving mode is determined according to a convention or indication information.

Optionally, the resource location of the first type of signal includes: a port, a time domain location.

After acquiring an interference measurement receiving mode configuration according to the convention, the user equipment may determine the port, the time domain location or other resource locations associated with the interference measurement receiving mode.

It should be noted that the above-mentioned indication information refers to configured information by the network-side device. After acquiring an interference measurement receiving mode configuration according to the indication information, the user equipment may determine the port, the time domain location or other resource locations associated with the interference measurement receiving mode.

It should be noted that the explicit manner of feedback is to feed back a size of feedback interference, interference correlation matrix or other information that can directly reflect the interference measurement result. And the implicit manner of feedback is that a determined CQI is sent to the network-side device after being combined with a signal measurement part.

Through the steps above, the problem in the related art that since increasing of the number of receiving antennas leads to different interference measurement criteria among UEs, the UE cannot objectively reflect the actual interference, and it is difficult for the network-side device to control interference measurement on the UE, is solved, and effects that the UE better predicts true interference during transmission and provides more dimensions for interference coordination for the network-side device, are achieved.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the foregoing embodiment can be implemented by means of software with a necessary general hardware platform, and can also be implemented by means of hardware, but in many cases the former is a better implementation.
