Description

Interference processing method, base station and terminal

Technical Field

The present invention relates to the field of communication technology, and in particular to an interference processing method, a base station and a terminal.

Background technique

In a dynamic time division duplexing (TDD) system, if adjacent cells perform transmissions in different directions at the same time, it is easy to cause cross-link interference (CLI) between cells. For example, as shown in Figure 1, gNB2 performs downlink transmission to UE2, and gNB1 schedules UE1 to perform uplink transmission, causing UE1's transmission to interfere with UE2's reception, which is called end-to-end cross-link interference (UE-to-UE CLI).

Generally, in order to identify the severity of the aforementioned end-to-end cross-link interference, interference measurement is required. For example, UE1 performs PUSCH transmission based on the scheduling of gNB1, and UE2 performs interference measurement based on the triggering of gNB2. However, in the prior art, there is no relevant solution for how to configure interference measurement resources between base stations.

The target interference measurement result may be an interference measurement result measured by the second terminal on an interference measurement resource, and the interference measurement resource may be determined by the second base station according to the first indication information.

In this embodiment, the interference measurement resource may be determined by the second base station according to the first indication information. For example, the interference measurement resource may be part or all of the first uplink resource indicated by the first indication information.

The above-mentioned target interference measurement result may be part or all of the interference measurement result directly measured by the second terminal on the interference measurement resource, or may be the interference measurement result obtained by calculating the interference measurement result directly measured by the second terminal on the interference measurement resource, which is not limited in this embodiment.

Optionally, the target interference measurement result may be received from the second base station via an interface between the first base station and the second base station. For example, the target interference measurement result may be received via one of an X2 interface, an Xn interface, an S1 interface, and an NG interface.

In an optional implementation, the first base station may receive a target interference measurement result from the second base station after sending the first message to the second base station.

For example, scheduling the first terminal with relatively large interference to send uplink signals may be avoided, scheduling the first terminal with relatively large interference to send uplink signals may be reduced, or an interference coordination request may be sent to the second base station; and so on.

In an optional implementation, after receiving the target interference measurement result from the second base station, the first base station may perform interference reduction processing according to the target interference measurement result.

In this embodiment, the first base station may perform interference reduction processing according to the target interference measurement result, so as to reduce cross-link interference.

Based on the set of terminals, an interference reduction process is performed.

In this embodiment, the target interference measurement result may include one or at least two interference measurement quantities. The preset condition may be set corresponding to the type of interference measurement quantity. For example, for RSRP, the preset condition may be that the RSRP value is less than the first threshold, or the RSRP value is ranked in the top N in descending order; for SINR, the preset condition may be that the SINR value is greater than the second threshold, or the SINR value is ranked in the top M in descending order. Among them, the first threshold and the second threshold may be reasonably set according to the actual situation, and N and M are positive integers.

In practical applications, the interference measurement resources corresponding to the interference measurement quantity representing the larger interference, that is, the target interference measurement resources, can be obtained, and then the terminal set that has been scheduled on the target interference measurement resources can be determined according to the historical scheduling information of the first base station, so that interference reduction processing can be performed based on the terminals in the scheduled terminal set.

Optionally, the performing interference reduction processing based on the terminal set may include:

Optionally, the performing interference reduction processing based on the terminal set may include:

During a time period when the second base station performs downlink transmission, interference reduction processing is performed based on the terminal set.

For example, during the time period when the second base station performs downlink transmission, processing to avoid scheduling terminals in the terminal set to send uplink signals can be performed; or during the time period when the second base station performs downlink transmission, processing to reduce scheduling terminals in the terminal set to send uplink signals can be performed.

It should be noted that, during the time period when the second base station does not perform downlink transmission, the first base station may not perform interference reduction processing, for example, perform uplink transmission scheduling in an existing manner.

In this embodiment, during the time period when the second base station performs downlink transmission, interference reduction processing is performed based on the terminal set, which can not only reduce cross-link interference but also improve the accuracy of uplink transmission scheduling.
