Description

Remote interference management method, base station, electronic device, and readable storage medium

technical field

The present application relates to the field of wireless communication technologies, and in particular, the present application relates to a remote interference management method, a base station, an electronic device, and a readable storage medium.

Background technique

Wireless communication systems that use the same frequency resource for uplink and downlink communication, including Time Division Duplex (TDD) systems and simultaneous full-duplex systems at the same frequency, will have atmospheric ducting (Atmosphericducting) leading to remote base station interference (Remote Interference) The phenomenon. Atmospheric ducting is a physical phenomenon that usually occurs in certain weather conditions when the Earth's atmosphere is highly thinned and causes a reduction in the refraction factor, which bends the signal toward the Earth's surface. Atmospheric ducting often occurs during seasonal changes, for example, or during winter in coastal areas. In such an environment, the wireless signal may face a small attenuation, and thus propagate to a farther place than the normal radiation propagation range, which will lead to the generation of transmission between the base stations that are far apart in the system using the same frequency for uplink and downlink communication. Strong interference will seriously affect network performance. Then, an effective remote interference management (Remote Interference Management, RIM) method is required to assist the network to reduce or avoid remote interference and ensure network performance.

Usually in a TDD communication system, such as the TDD system protocol formulated by the 3rd Generation Partnership Project (3GPP), there will be a blank time interval (Gap) to avoid the downlink transmission of the base station from seriously interfering with the Upstream reception. But when atmospheric ducting occurs, a very large gap will need to be configured to achieve the above. If a larger gap is always configured, the spectrum usage rate will be too low, while configuring a smaller gap will cause serious remote base station interference when atmospheric ducts occur. In response to this phenomenon, 3GPP has initiated corresponding research and proposed a variety of remote interference management frameworks. As described in 3GPP technical report TS38.866, one of the core issues of remote interference management is how to detect the interfering base station (Aggressor gNB), and implement measures that can reduce the interference to the interfered base station (Victim gNB), and how to restore the base station to the normal network operation without the atmospheric duct when the remote interference phenomenon of the atmospheric duct is found to disappear, so as to improve the network performance and efficiency.

Therefore, in order to solve the above-mentioned core problems and provide enough flexibility for remote interference management to ensure the performance and effectiveness of remote interference management, a flexible management mechanism is urgently needed to configure various remote interference management references in remote interference management. Signal (Remote Interference Management Reference Symbol, RIM-RS) communication resource.

In view of the problems existing in the prior art, the present application proposes a flexible and unified configuration of a remote interference management reference signal and a corresponding remote interference management configuration indication method, which can be applied to the above-mentioned remote interference management architecture, which is 3GPP One of the interference management architectures in the technical report TS38.866, this application proposes a flexible and unified remote interference management reference signal configuration and the corresponding remote interference management configuration indication method, which can also be applied to other 3GPP technical report TS38.866. Disruption Management Architecture. The solution of the present application can simplify the configuration of signaling exchange information, and provide flexibility in the configuration/communication indication of the remote interference management reference signal with multiple functions.

The embodiment of the present application provides a remote interference management method, as shown in FIG. 2 , the method includes:

Step S201: the base station determines the mapping relationship between the base station set identifier and the remote interference management reference signal according to the received configuration information;

Step S202: the base station sends the remote interference management reference signal according to the assigned base station set identifier and according to the mapping relationship;

Step S203: The base station detects the remote interference management reference signal, determines the base station set identification information through the detected remote interference management reference signal according to the mapping relationship, and reports the determined base station set identification information.

In this embodiment of the present application, the base station may receive configuration information configured by an Operation Administration and Maintenance (OAM) unit of the network, and then in step S201, determine the relationship between the base station set identifier and the remote interference management reference signal according to the configuration information to simplify the signaling interaction. In this way, the network can effectively configure the RIM-RS resources through the gNB ID/gNB set ID, and the base station can obtain the corresponding gNB ID/gNB set ID information through the detected RIM-RS to facilitate interference management.

Among them, the base station set ID specifically includes the base station ID (gNB ID) and the base station set ID (gNB set ID). When there is only one base station in the base station set, the gNB set ID is the gNB ID, that is, the gNB ID is the gNB set ID. When there is only one base station For the convenience of description, in the embodiment of this application, the gNB set ID of the base station set is uniformly used for description.

Further, the base station performs step S202 and/or step S203 according to the above mapping relationship;

It should be noted that the sequence of step S202 and step S203 can be changed, for example, the RIM-RS1 is detected first and then the RIM-RS2 is sent. In practical applications, for different base stations, each base station may perform step S202 and/or step S203 for interaction to complete remote interference management.

Specifically, the base station can receive the gNB set ID(s) with a predetermined bit length allocated by the OAM (for convenience of description, the following is described in terms of L bit length), and then in step S202, the base station, according to the gNB set ID, according to the gNB set ID (s) The mapping relationship between the ID and the RIM-RS, when the transmission trigger condition is satisfied, the RIM-RS is transmitted until the transmission stop information is received.

In practical applications, the OAM may be configured with one or more detection time windows, and the base station may report the detected gNB set ID information after performing RIM-RS detection within the detection time window.

The remote interference management method provided by the embodiment of the present application determines the mapping relationship between the base station set identifier and the remote interference management reference signal according to the received configuration information, and then transmits and/or transmits the remote interference management reference signal based on the mapping relationship. The detection simplifies the signaling exchange information, and improves the flexibility of the configuration/communication indication of the remote interference management reference signal with multiple functions.

In the embodiment of the present application, in order to better cope with the remote interference caused by atmospheric waveguides, the TDD network can be configured with the following types of remote interference management reference signals for remote interference management:

(2) Remote Interference Management Reference Signal for Near-Base Station Interference Detection (also known as RIM-RS1 for "Near-Base Station Interference Detection")

Among them, the RIM-RS1 of "near base station interference detection" and the RIM-RS1 of "far base station interference detection" are respectively used for the interference detection of near/far (near/far) base stations; specifically, the RIM-RS1 of "far base station interference detection" RS1 and RIM-RS1 of "near base station interference detection" correspond to the relative distances of the two RIM-RSs relative to a certain time reference point. The larger relative distance is used for far base station interference detection, and the smaller relative distance is used for near base station interference. In the actual configuration, the near/far attribute of the RIM-RS can be implicitly judged by the relative distance, without indicating it explicitly.

(3) Remote interference management reference signal for indicating whether remote interference still exists (also called RIM-RS2 for "detecting whether remote interference still exists")

The RIM-RS2 is used by the Aggressor gNB (interfering base station) to inform the Victim gNB (interfered base station) whether the long-range interference caused by the atmospheric waveguide still exists.

In addition, the following two types of remote interference management reference signals can be configured:

(1) Remote Interference Management Reference Signal indicating Not enough mitigation (also referred to as RIM-RS1 indicating "Insufficient Interference Mitigation")

This RIM-RS1 is used by the Victim gNB to transmit when it suffers from interference characteristic of atmospheric duct interference.

(2) Remote Interference Management Reference Signal indicating Enough Mitigation (also referred to as RIM-RS1 indicating "Enough Mitigation")

This RIM-RS1 is used by the Victim gNB to send when the interference is found to be reduced to an acceptable level.

The embodiment of the present application provides a feasible implementation manner, and the configuration information of the OAM configuration includes but is not limited to at least one of the following:

(1) Down and Up Pattern Period P

Specifically, it is a single downlink uplink pattern periodicity (DL-UL pattern periodicity) or a cascade downlink uplink pattern periodicity (concatenated DL-UL pattern periodicity).

Among them, the single downlink and uplink period _P includes MP = 1 downlink and uplink switching point (DL-UL switching point), and the single downlink and uplink pattern period P is the one downlink and uplink pattern switching period (DL-UL switching period, also called DL-UL switching point). is the cycle length of the down and up conversion cycle).

The cascade down and up pattern period P is formed by the cascade of M _P ≥ 2 down and up patterns, including M _P down and up conversion points, and the cascade down and up pattern period P is the conversion period corresponding to the M _P down and up patterns respectively The sum of p _n , i.e.

个RIM-RS发送时机，T₂时间段包含

个RIM-RS发送时机，时间段的划分是以P为单位，即时间段是P的整数倍。As an example, the time period allocation information may include: dividing the transmission period T into two time periods, the former time period being the RIM-RS1 time period, and the latter time period being the RIM-RS2 time period. Then, the time period allocation information can be configured according to T ₁ =N ₁ ×P and T ₂ =N ₂ ×P, respectively. Among them, the _T1 time period includes

RIM _- RS transmission occasions, the T2 time period includes

For each RIM-RS transmission opportunity, the time period is divided in units of P, that is, the time period is an integer multiple of P.

Alternatively, the time period allocation information can be directly configured as: the N ₁ ×M _p RIM-RS transmission timings are the previous time period, which is used for RIM-RS1; and the N ₂ ×M _p RIM-RS transmission timings are the next time period The time period is used for RIM-RS2, and the division of the time period is based on the RIM-RS transmission timing, that is, the time period is an integer multiple of the RIM-RS transmission timing.

It can be understood that the case of M _p =1 is also applicable to the above two methods.

The RIM-RS transmission period T is segmented before and after, and the RIM-RS1 and the RIM-RS2 are sent respectively, so as to ensure the respective functions and reduce the waiting time, and at the same time, the configuration signaling can be simplified.

(4) The number of repetitions R _x of each type of remote interference management reference signal

That is, the number of repetitions Rx of RIM-RS1 for "near base station interference detection", RIM-RS1 and RIM-RS2 for "far base station interference detection", _x ={a, b, c}.

Specifically, the number of repetitions R _a of RIM-RS1 of "near base station interference detection", the number of repetitions of RIM-RS1 of "far base station interference detection" R _b and the number of repetitions of RIM-RS2 R _c can be configured separately or uniformly, That is, the repetition times of each type of remote interference management reference signal can be configured to be the same or different.

In a possible implementation manner, the number of repetitions of the remote interference management reference signal used for far base station interference detection is the same as the number of repetitions of the remote interference management reference signal used for near base station interference detection, that is, the RIM of "far base station interference detection". - The number of repetitions of RS1 and the number of repetitions of RIM-RS1 of "near base station interference detection" can be configured to be the same, then the number of repetitions of RIM-RS1 can be directly indicated as R=R _a +R _b .

In the embodiment of the present application, the configuration information of the OAM configuration may further include: the transmission symbol position of the remote interference management reference signal in the RIM-RS transmission occasion.

The OAM also configures a specific RIM-RS to be located at a specific symbol-level position within the uplink-downlink conversion period. That is, the RIM-RS transmission timing is the time domain location information of the downlink/uplink conversion cycle level. In this downlink/uplink conversion period, the OAM can configure a reference time point of the RIM-RS symbol-level transmission time.

For example, the reference time point is the downlink transmission boundary in the downlink and uplink pattern transition period. You can refer to the TDD-UL-DL-Config Common configuration information in the 3GPP TS38.331 document to configure the downlink transmission boundary, and then configure the RIM-RS symbol-level transmission The starting position is the symbol number relative to the reference time point.

For example, the RIM-RS occupies 2 OFDM symbols. If the downlink transmission boundary is configured as the boundary of the last downlink slot in the downlink and uplink pattern as the reference time point, and a slot has 14 symbols, then the RIM-RS The starting position of the RIM-RS can be configured as the 0-12th symbol of the time slot where the reference time point is located; if the downlink reference time point is configured as the last downlink symbol in the downlink and uplink pattern, then the position of the transmitted symbol of the RIM-RS It can be configured as the first two symbols of the downlink reference time point, and the boundary alignment of the reference time point is consistent with the boundary alignment of the reference time point. The above are only schematic configuration diagrams of symbol-level positions, and should not be construed as a limitation on the embodiments of the present application.

Further, the base station can determine the mapping relationship between the L-bit gNB set ID and the RIM-RS in the network according to the above configuration information, which can also be called a mapping rule (Mapping Rule) or a unified mapping rule.

This embodiment of the present application provides a feasible implementation manner for step S202, which specifically includes:

Step S2021: the base station obtains the remote interference management reference signal resource information in the transmission period corresponding to the base station set identifier according to the base station set identifier and the above mapping relationship;

That is, according to the determined mapping rule between the RIM-RS resource information of the RIM-RS in the transmission period T and the gNB set ID, the base station can obtain the corresponding RIM-RS resource information according to the configured gNB set ID, such as RIM _- Sequence domain information, time domain information and frequency domain information {If, _Io , _Is } of RS resource configuration.

In remote interference management, the base station can be notified to receive the L-bit gNB set ID configured by the OAM, and the base station can automatically obtain the corresponding RIM-RS resource information through the gNB set ID.

Step S2022: The base station sends the remote interference management reference signal on the resource corresponding to the resource information of the remote interference management reference signal according to the transmission period.

Specifically, when the transmission trigger condition is satisfied, the RIM-RS is transmitted on the corresponding resource with the transmission period T as a period until the transmission stop information is received, for example, the transmission is performed at the corresponding RIM-RS time and frequency domain position.

Similarly, in step S203 of the embodiment of the present application, the base station obtains the corresponding L-bit long _gNB set ID information through the detected RIM-RS information {If, _Io , _Is }, and reports it.
