Description

Signal measurement method, device and network equipment

Technical Field

The present invention relates to the field of wireless technology, and in particular to a signal measurement method, device and network equipment.

Background Art

When ground base stations and non-ground base stations are networked at the same frequency, the terminals of the ground network and the terminals of the non-ground network will be strongly interfered by each other. Among them, non-ground base stations include: High Altitude Platform Station (HAPS) and satellites. The networking of ground base stations and non-ground base stations is sometimes also called space-ground networking or space-ground integrated network.

Considering the interference of non-ground base stations to ground UEs, since non-ground base stations are far away from the ground and have large transmission power, no matter the ground UE is in the center of the ground base station cell or at the edge of the ground base station cell, the interference signal strength received by it from non-ground base stations is similar and the interference is strong. Conversely, ground base stations will also generate strong interference to non-ground base station UEs.

Therefore, compared with the pure ground network co-frequency networking scenario, the cell interference problem between different networks will become more serious when the ground base station and the non-ground base station are co-frequency networked.

DETAILED DESCRIPTION

In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

In response to the serious cell interference problem between different networks when the same frequency is networked, an embodiment of the present invention provides a signal measurement method, which configures different terminals to work in different sub-bands of the bandwidth according to the terminal capabilities and the address locations of the terminals, so as to avoid the serious cell interference problem between different networks.

The working principle of the signal measurement method according to the embodiment of the present invention is as follows:

At present, more and more terminals will support multi-antenna transceiver capabilities. Based on the beamforming capability of multiple antennas, terminals can generate narrower antenna beams. Through the beamforming algorithm, the terminal can align the center of the narrow beam with the serving base station, and align the beam sidelobe or beam zero limit position with the interference signal, effectively improving the channel quality. Therefore, the above terminals can work normally in the same frequency networking scenario.

Considering that the antenna beam has a certain width, whether the terminal can effectively suppress interference from other cells depends not only on the generated beam width, but also on the direction of the useful signal of the serving cell and the interference signal of other cells.

Taking into account the different capabilities of terminals in the existing network, some terminals have a large number of antennas and can form very narrow receiving beams, while some terminals have a small number of antennas. Low-cost terminals are even only equipped with omnidirectional antennas. That is, UEs in the existing network have different beam widths.

Similarly, depending on the location of the UE, the angle between the directions of the useful signal from the serving cell and the interference signal from other cells received by it is also different. In some locations, the angle is large, and the interference suppression capability based on the UE antenna shaping is strong; in some locations, the angle is small, and the interference suppression capability based on the UE antenna shaping is weak.

In summary, for terminals with narrow beam receiving and transmitting capabilities and in a better geographical location (that is, the angle between the incoming wave directions of the useful signal from the service cell and the interference signal from other cells is larger), better interference suppression capabilities can be obtained in the same frequency networking scenario through the antenna shaping algorithm.

However, for a terminal with fewer antennas or a bad geographical location, it is not possible to suppress interference from other cells well.

To address the above issues, different cells can divide the working bandwidth into at least three parts, as shown in Figure 1. For example, taking the working bandwidth division of two cells as an example, the first dedicated subband is exclusive to the first cell (can be configured to the first terminal set), the second dedicated subband is exclusive to the second cell (can be configured to the second terminal set), and the mixed subband can be shared by the two cells (can be configured to the third terminal set and the fourth terminal set, respectively).

For example, in a ground-ground integrated scenario, all non-ground base stations may be configured with first dedicated subbands, all ground base stations may be configured with second dedicated subbands, and non-ground base stations and ground base stations may share hybrid subbands.

It should be noted that the above working bandwidth allocation method is not limited to being applied to the ground-ground integrated scenario, but can also be extended to other scenarios, such as a pure ground network. In this pure ground network, the above-mentioned first cell and second cell can also be on the ground. In this case, interference management may be performed between different private networks on the ground, or between access nodes of two fixed networks.

Therefore, the signal measurement method in the embodiment of the present invention can solve the serious cell interference problem between different networks during co-frequency networking, and is not limited to the application scenarios of different networks.

The signal measurement method described in the embodiment of the present invention can configure different terminals to work in different sub-bands in consideration of the differences in terminal capabilities and address locations of the terminals.

In order to clearly illustrate the technical solution of the method described in the present invention, the method described in the embodiment of the present invention is illustrated below by taking the space-ground networking scenario as an example.

For example, for a ground network, the dedicated bandwidth is the first dedicated sub-band. Then, the ground base station may consider scheduling terminals of the ground network with a small number of antennas or a bad geographical location to work in the first dedicated sub-band. The terminals scheduled to work in the first dedicated sub-band may be referred to as a first terminal set.

For the terminals of the ground network with narrow beam transceiver capability and in a better geographical location, they can be scheduled to work in the hybrid sub-band. The terminals scheduled to work in the hybrid sub-band can be called the third terminal set.

Similarly, for non-terrestrial networks, the dedicated bandwidth is the second dedicated sub-band. Then, the non-terrestrial base station can consider scheduling the terminals of the non-terrestrial network with a small number of antennas or a bad geographical location to work in the second dedicated sub-band. The terminals scheduled to work in the second dedicated sub-band are called the second terminal set.

The terminals of non-terrestrial networks that have narrow beam transceiver capability and are in a relatively advantageous geographical location are scheduled to work in the hybrid sub-band. The terminals scheduled to work in the hybrid sub-band are referred to as a fourth terminal set.

With the above configuration, the terminals working in the first dedicated sub-band and the second dedicated sub-band are protected from interference from other networks because the base station uses frequency division multiplexing technology. The terminals working in the hybrid sub-band are protected from interference from other networks because of their own antenna shaping capabilities. Obviously, compared with pure frequency multiplexing technology, the use of hybrid sub-bands will significantly save network spectrum resource overhead.

According to the above principles, it is obvious that if the base station can distinguish different terminals and configure different terminals to work in different subbands in dedicated subbands and hybrid subbands according to the capabilities and locations of the terminals, serious cell interference problems between different networks can be avoided.

Note that there are two implementation methods for scheduling the terminal to a specific subband mentioned above.

The terminal is configured with a bandwidth part (Bandwidth Part, BWP) including dedicated subbands and hybrid subbands. The base station schedules the terminal through downlink control information (Downlink Control Information, DCI) to indicate which subband the terminal works in;

A plurality of different BWPs are configured for the terminal, and some BWPs work in dedicated subbands, while some BWPs work in hybrid subbands. When the base station intends to instruct the terminal to work in the dedicated subband, the UE is instructed to use the first BWP through at least one of Radio Resource Control (RRC) signaling, Media Access Control (MAC) control element (CE) and DCI, wherein the first BWP works in the dedicated subband; and/or, when the base station intends to instruct the terminal to work in the hybrid subband, the UE is instructed to use the second BWP through at least one of RRC signaling, MAC CE and DCI, wherein the second BWP works in the dedicated subband.

In an embodiment of the present invention, the base station configures the terminal to use the same spatial filter (or spatial relationship) to receive the service signal and the interference signal, and reports the measurement results. The base station can determine the transmission parameters for the service provided by the base station to the terminal based on the measurement results, so as to configure the terminal to operate in a dedicated subband or a hybrid subband, thereby avoiding serious cell interference problems between different networks.

The signal measurement method described in the embodiment of the present invention, in one implementation manner, is applied to a terminal, as shown in FIG2 , and the method includes:

S210, determining a first reference signal and a second reference signal; wherein the second reference signal is sent by a serving cell of the terminal;

S220, determining a spatial relationship of the first reference signal according to the second reference signal;

S230, measuring the first reference signal and/or the second reference signal according to the spatial relationship to obtain measurement information;

S240: Report the measurement information.

Using the signal measurement method described in the embodiment of the present invention, the terminal uses the same spatial relationship (or spatial filter) to measure the first reference signal and/or the second reference signal, and reports the measurement results, so that the base station can determine the transmission parameters for the service provided by the base station to the terminal based on the measurement results, configure the terminal to operate in a dedicated subband or a hybrid subband, and avoid serious cell interference problems between different networks.

In the embodiment of the present invention, optionally, the first reference signal is an interference signal sent by a non-serving cell of the terminal, and the second reference signal is a signal sent by a serving cell of the terminal.

Optionally, the first reference signal and the second reference signal may be downlink reference signals, such as a channel state information-reference signal (CSI-RS), or a synchronization signal and a physical broadcast channel (PBCH) block (Synchronization Signal and PBCH block, SSB).

Optionally, in step S240, the reported measurement information may include at least one of a signal strength of a first reference signal, a signal strength of a second reference signal, and a signal to interference plus noise ratio (SINR).

Among them, the signal to interference plus noise ratio SINR can be calculated and determined by the following method:

SINR = S/(I+N);

Wherein, S represents the signal strength of the second reference signal, I represents the interference signal strength, and I at least includes the signal strength of the first reference signal, and N represents the noise strength.

Optionally, the terminal may report the signal strength of the first reference signal and the signal strength of the second reference signal simultaneously in one measurement report; may also report the signal strength of the first reference signal and the signal strength of the second reference signal respectively in different measurement reports; or may only report SINR.

That is, in step S240, when reporting measurement information, the terminal may report only one of the signal strength of the first reference signal, the signal strength of the second reference signal, and the SINR; or may report the signal strength of the first reference signal, the signal strength of the second reference signal, and the SINR separately in multiple times.

The serving base station of the terminal determines whether to schedule the terminal to a dedicated subband or a mixed subband based on the measurement information reported by the terminal.

For example, when the terminal feeds back the signal strength of the second reference signal and the signal strength of the first reference signal, if the signal strength of the second reference signal is higher than the signal strength of the first reference signal by a certain threshold, the terminal is allowed to be scheduled to the hybrid subband; otherwise, the terminal is only scheduled to the dedicated subband.

When the terminal feeds back the SINR, if the SINR is greater than a certain threshold, the terminal is allowed to be scheduled to the hybrid subband; otherwise, the terminal is only scheduled to the dedicated subband.

By adopting the signal measurement method described in the embodiment of the present invention, no matter how the interfering base station performs service scheduling on the hybrid subband, it will not cause significant interference to the terminal on the serving base station. Therefore, the method has the advantage of high reliability.

The signal measurement method described in the embodiment of the present invention may, optionally, be applied in a space-ground networking scenario, including ground base stations and non-ground base stations.

Among them, non-ground base stations include high altitude platforms (HAPS) and satellites. Since the non-ground platform is higher than the ground, the coverage radius is very large (hundreds to thousands of km). When the projections of the ground base station and the non-ground base station on the ground are far apart, the distances from the ground terminal (which may be the UE of the ground network or the UE of the non-ground network) to the two base stations are significantly different. Even in the case of timing synchronization between the ground network and the non-ground network, due to the influence of space propagation delay, the distance between the terminal on the ground and the ground base station may be only a few hundred meters, but the distance to the non-ground base station may be hundreds to thousands of kilometers. Therefore, the signal measurement method described in the embodiment of the present invention needs to ensure that within one OFDM symbol, the signals sent by the ground base station and the non-ground base station can be fully received at the same time.

To implement the signal measurement method described in the embodiment of the present invention, optionally, in one implementation mode, the terminal uses the same receiving beam and different timing relationships to respectively receive signals from different networks.

Taking the space-ground network as an example, the signals from the ground base station and the non-ground base station are received respectively with the same receiving beam and different timing relationships.

For example, taking the terminal of the ground network in the space-ground network as an example, the terminal listens to the reference signal sent by the non-ground network within the configured measurement window. That is, the terminal listens to the SSB sent by the non-ground base station within the configured measurement window to obtain the timing relationship of the non-ground base station. According to the configuration of the ground service base station, the terminal can directly report the signal strength of the SSB sent by the non-ground base station, or report other reference signals sent by the non-ground base station, such as the signal strength of the CSI-RS.

It should be noted that: within the measurement window, the terminal needs to use the first spatial filter to receive the signal strength of the interfering cell, wherein the terminal uses the first spatial filter to receive the reference signal for measuring the channel quality of the serving cell, such as SSB and/or CSI-RS.

The “spatial filter” is also the “spatial relationship” in the present invention, or the “quasi co-location (QCL) relationship”, or the “QCL type A relationship”.

In some embodiments, the terminal will perform layer 3 filtering on the measurement results.

Therefore, in the embodiment of the present invention, optionally, in step S210, the first reference signal and the second reference signal are determined according to that the first reference signal is an interference signal sent by a non-serving cell and the second reference signal is a signal sent by a serving cell of the terminal.

In this embodiment, optionally, the method further comprises:

Determine the measurement interval based on high-level configuration;

Wherein, in step S230, measuring the first reference signal according to the spatial relationship to obtain measurement information includes:

In the measurement interval, the first reference signal is measured according to the spatial relationship of the first reference signal to obtain the measurement information.

Optionally, the second reference signal is determined according to a preset rule or configured by a higher layer.

Optionally, the first reference signal is configured by a higher layer.

In an embodiment of the present invention, optionally, the first reference signal includes at least one of a synchronization signal block SSB, a channel state information reference signal CSI-RS and a mobility CSI-RS.

The second reference signal includes at least one of the following: an SSB sent by a serving cell, a CSI-RS sent by a serving cell, a tracking reference signal (TRS) sent by a serving cell, a DMRS, etc.

In one embodiment, the second reference signal is determined according to a preset rule. For example, the second reference signal includes at least one of the following:

The SSB with the best channel measurement quality sent by the serving cell;

The CSI-RS with the best channel measurement quality sent by the serving cell;

The demodulation reference signal (DMRS) included in the most recent physical downlink shared channel (PDSCH) transmission sent by the serving cell;

A reference signal determined by a transmission configuration indication (TCI) field indicated in the downlink control information (DCI) of the most recent physical downlink shared channel (PDSCH) transmission scheduled by the serving cell;

Reference signal determined according to the default TCI.

In another embodiment, the second reference signal is configured by a higher layer, that is, the base station explicitly configures the second reference signal used by the UE through higher layer signaling.

Optionally, measuring the first reference signal according to the spatial relationship includes:

The first reference signal is measured using the same spatial filter or quasi-co-site QCL relationship as the second reference signal.

Optionally, the QCL relationship includes at least a QCL type D relationship. In an embodiment of the present invention, optionally, the second reference signal is configured by a high layer, including:

The correspondence between the first reference signal and the second reference signal is indicated through high-layer signaling.

Optionally, a description of the QCL relationship with the RS (second reference signal) of the serving cell may be added to the RS configuration used for radio resource management (RRM) measurement, such as adding a QCL-related reference signal index: RS index to the RS configuration.

The RS index may be a CSI-RS index or an SSB index, and the terminal determines the RS used for RRM measurement, which has a QCL type-D relationship with the SSB or CSI-RS with the RS index in the serving cell.

The QCL type-D relationship can also be described as the terminal using the same spatial domain filter to receive the above two types of layer signals.

It should be noted that the second reference signal is determined according to the TCI field indicated in the DCI sent by the serving cell for the most recent scheduling of PDSCH transmission; including: including the TCI field in the DCI. The terminal determines the associated reference signal based on the TCI field, such as the SSB or CSI-RS with the indicated number.

In another embodiment of the present invention, optionally, the first reference signal is a reference signal having a time domain cyclic shift structure.

Taking the Remote Interference Management-ReferenceSignal (RIM-RS) as an example, as shown in Figure 3, the reference signal occupies 2 OFDM symbol lengths and has a time domain cyclic shift structure, so that the receiving end can always receive an RS time domain component in a normal uplink symbol, and the time domain component has a complete and phase-continuous time domain sequence in the uplink symbol, and the receiving end can detect it normally.

By adopting this implementation mode, when applied in a space-ground networking scenario, the ground network and/or the non-ground network sends a reference signal having a time domain cyclic shift structure.

In one embodiment, the reference signal sent by the non-terrestrial network has a time domain cyclic shift structure, and the duration is greater than the time domain length of two orthogonal frequency division multiplexing (OFDM) symbols of the terrestrial network. In this way, the terminal of the terrestrial network can normally receive the reference signal sent by the non-terrestrial network in the uplink symbol according to the uplink timing of the terrestrial network, and measure its signal quality (i.e., interference signal strength).

In another embodiment, the reference signal sent by the terrestrial network has a time domain cyclic shift structure, and the duration is greater than the time domain length of two OFDM symbols of the non-terrestrial network. In this way, the terminal of the non-terrestrial network can normally receive the reference signal sent by the terrestrial network in the UL symbol according to the uplink timing of the non-terrestrial network, and measure its signal quality.

In another embodiment, both the terrestrial network and the non-terrestrial network send reference signals with a time domain cyclic shift structure. Terminals of the terrestrial network and the non-terrestrial network can normally receive reference signals from other networks in uplink symbols based on their own uplink timing and measure their signal quality.

Specifically, regarding the reference signal type with a time domain cyclic shift structure, it may be selected to allow a terrestrial network and/or a non-terrestrial network to send a RIM-RS.

Alternatively, the reference signal can be required to have the following form:

At port p, the time domain continuous signal of the reference signal is defined as:

in

_Nu = X·2048κ·2 ^-μ

Δf = 15·2 ^μ kHz, where μ is the subcarrier configuration;

The parameter k ₁ is the frequency domain offset;

L is the length of the reference signal sequence;

l ₀ is the starting symbol.

in,

Determined according to the following formula, and in the following formula, let l = l ₀ ;

in Determined according to the following formula, and in the following formula, let l = l ₀ ;

Therefore, in this implementation of the embodiment of the present invention, in step S210, a first reference signal and a second reference signal are determined according to a high-level configuration, and the first reference signal and/or the second reference signal are reference signals with a time domain cyclic shift.

Optionally, in this implementation, the second reference signal is sent by a serving cell of the terminal, and the second reference signal is an SSB and/or a CSI-RS for channel measurement.

Wherein, in step S220, determining the spatial relationship of the first reference signal according to the second reference signal includes:

Receiving the first reference signal using the same spatial filter as used for receiving the second reference signal;

Alternatively, the first reference signal is received using the same QCL relationship as the second reference signal.

In step S230, the first reference signal and/or the second reference signal is measured according to the spatial relationship to obtain measurement information, including at least one of the following:

measuring the RSRP of the first reference signal;

measuring the RSSI of the first reference signal;

Measuring SINR according to the first reference signal and the second reference signal;

Among them, SINR=S/(I+N); S represents the signal strength of the second reference signal, I represents the signal strength of the interference signal, and I at least includes the signal strength of the first reference signal, and N represents the strength of the noise.

Optionally, RSRP, RSSI and SINR are all L1 measurement results, that is, only L1 filtering is performed.

In the signal measurement method described in the embodiment of the present invention, the terminal adopts the same spatial relationship to receive the service signal and the interference signal and reports the measurement results, so that the base station can determine the transmission parameters for providing services to the terminal based on the measurement results, so as to configure the terminal to work in a dedicated subband or a hybrid subband, thereby avoiding serious cell interference problems between different networks.

Another aspect of the present invention is to provide a signal measurement method, which is applied to a base station. As shown in FIG4 , the method includes:

S410, receiving measurement information of a first reference signal and/or a second reference signal reported by a terminal; wherein the second reference signal is sent by the base station, and the terminal can determine a spatial relationship of the first reference signal according to the second reference signal.

The base station is a serving base station of the terminal.

By adopting the signal measurement method described in the embodiment of the present invention, the base station provides the terminal with transmission parameters of the service based on the measurement results reported by the terminal when receiving the service signal and the interference signal using the same spatial filter (or spatial relationship), so as to configure the terminal to operate in a dedicated subband or a hybrid subband, thereby avoiding serious cell interference problems between different networks.

Optionally, the signal measurement method further comprises:

When the measurement information includes the signal strength of the first reference signal and the signal strength of the second reference signal, if the signal strength of the second reference signal is greater than the signal strength of the first reference signal, and the difference between the signal strength of the second reference signal and the signal strength of the first reference signal is greater than or equal to a first preset threshold value, then scheduling the uplink data transmission service and/or the downlink data transmission service of the terminal on the first bandwidth; and/or, if the difference between the signal strength of the second reference signal and the signal strength of the first reference signal is less than the first preset threshold value, then scheduling the uplink data transmission service and/or the downlink data transmission service of the terminal on the second bandwidth;

or,

When the measurement information includes a measured signal to interference plus noise ratio SINR, if the SINR is greater than or equal to a second preset threshold value, scheduling the uplink data transmission service and/or the downlink data transmission service of the terminal on the first bandwidth, and/or, if the SINR is less than the second preset threshold value, scheduling the uplink data transmission service and/or the downlink data transmission service of the terminal on the second bandwidth;

The base station shares the first bandwidth with another base station.

Optionally, the signal measurement method further comprises:

When the measurement information includes the signal strength of the first reference signal and the signal strength of the second reference signal, if the signal strength of the second reference signal is greater than the signal strength of the first reference signal, and the difference between the signal strength of the second reference signal and the signal strength of the first reference signal is greater than or equal to a first preset threshold value, then the terminal is instructed to operate on a first bandwidth part BWP; and/or, if the difference between the signal strength of the second reference signal and the signal strength of the first reference signal is less than the first preset threshold value, then the terminal is instructed to operate on a second BWP;

or,

When the measurement information includes a measured signal to interference plus noise ratio SINR, if the SINR is greater than or equal to a second preset threshold value, instructing the terminal to operate on a first BWP, and/or, if the SINR is less than the second preset threshold value, instructing the terminal to operate on a second BWP;

The first BWP is located in a bandwidth shared by the base station and another base station.

Optionally, the signal measurement method further comprises:

Obtaining configuration of the first reference signal through at least one of network management configuration and interaction between base stations;

The configuration information of the first reference signal is indicated to the UE through at least one method of radio resource control RRC signaling, media access control layer control element (Media Access Control-Control Element, MAC CE), and downlink control information DCI.

Optionally, in the signal measurement method, the first reference signal includes at least one of a synchronization signal block SSB, a channel state information reference signal CSI-RS, a mobility CSI-RS and a remote interference management reference signal RIM-RS.

Optionally, in the signal measurement method, the second reference signal includes at least one of the following:

Tracking reference signal TRS;

The demodulation reference signal DMRS included in the most recent physical downlink shared channel PDSCH transmission;

The reference signal determined by the transmission configuration indication TCI field indicated in the downlink control information DCI for the most recent scheduled PDSCH transmission;

Reference signal determined according to the default TCI.

In one implementation of the signal measurement method described in the embodiment of the present invention, optionally, the base station determines the scheduling of the uplink channel based on the decision result of the downlink channel, that is, if the base station determines to schedule the downlink service of the UE on the hybrid subband, its uplink service will also be scheduled on the hybrid subband. Vice versa, that is, if the base station determines to schedule the downlink service of the UE on the dedicated subband, its uplink service will also be scheduled on the dedicated subband.

In another implementation, optionally, in a ground-to-ground networking scenario, base stations of the ground network and the non-ground network measure the uplink reference signal sent by the UE, and notify the other base stations of the measurement results through backhaul signaling. The serving base station determines whether to schedule the UE to a dedicated subband or a hybrid subband based on the information notified by the interfering base station through backhaul signaling.

Optionally, the uplink reference signal includes at least: a channel sounding reference signal (Sounding Reference Signal, SRS).

In one embodiment, the serving base station is a base station of a terrestrial network, and the interference signal comes from a non-terrestrial network. For example, the serving base station of the terrestrial network can configure the UE to send SRS with the best spatial relationship (i.e., let the UE point the antenna transmission beam to the serving base station when sending SRS), and notify the SRS configuration signal to the base station of the non-terrestrial network through backhaul signaling. The non-terrestrial base station detects the SRS sent by the UE to determine whether it will cause interference to its own UL service reception.

For example, a non-terrestrial base station uses the same spatial filter to receive the UL signal sent by the UE it serves and the SRS sent by the UE in other cells. If it is found that the SRS received signal sent by the UE in other cells is strong, it means that it will cause greater interference to its own UL service. The non-terrestrial base station will request the terrestrial network base station not to schedule the UE to the hybrid subband.

The reverse is also true. I will not go into details here.
