However, in the uplink positioning operation, the SRS transmitted by the ue needs to reach different base stations, and the distances between the different base stations and the ue are different, and more importantly, when the SRS signal reaches the base station receiver, the base station needs to be able to accurately listen and detect the SRS signal, so as to further perform the estimation of the time delay and the angle. In the process of interception and detection, a key condition is that the interference suffered by the SRS signal is low, and meanwhile, the received signal-to-noise ratio is high, so that the accuracy and precision of positioning can be ensured. Therefore, how to configure the SRS signal to achieve more accurate uplink positioning becomes a problem to be solved.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a method for configuring a positioning sounding reference signal according to an embodiment of the present invention is applied to a user equipment, and includes:

step 101, receiving first configuration information of a positioning detection reference signal; wherein the content of the first and second substances,

Through this step, the UE receives first configuration information of a positioning sounding reference signal SRS, so as to transmit the SRS signal based on the first configuration information. If the first configuration information includes a first resource set for transmitting SRS signals and a transmission power adjustment factor corresponding to the first resource set, the SRS signals may be transmitted after the transmission power is adjusted based on the transmission power adjustment factor, and different power adjustment factors may correspond to different target receiving base stations, so that more applicable transmission power is used; if the first allocation information includes a second resource set for transmitting the SRS signal, the second resource set belongs to a preset allocation resource pool, and resources in the allocation resource pool are orthogonal to each other, and resources used for transmitting the SRS signal are orthogonal to other resources, so that interference can be reduced. In this way, the SRS signal is transmitted based on the first configuration information, and more accurate uplink positioning can be achieved.

It should be noted that, the specific implementation of the resource set configured on the network side for transmitting the SRS signal may be a resource set, where each resource corresponds to a receiving end, e.g., { resource 1, resource 2, resource 3}, where the high-level signaling configures resource 1 corresponding to base station 1, resource 2 corresponding to base station 2, and resource 3 corresponding to base station 3 in advance; the UE may be a plurality of resource sets, each resource set corresponds to a receiving end, such as resource set a and resource set B, the resource set a corresponds to the base station 1 in advance configured by the high-level signaling, and the resource set B corresponds to the base station 2, where the resource in the resource set corresponding to the receiving end may be used for the UE to send the SRS signal to the receiving end. The number of the first and second electrodes, therefore,

the first resource sets correspond to the transmission power adjustment factors one by one; alternatively, the first and second electrodes may be,

In this way, for a specific implementation form of the resource set, the transmit power adjustment factor in the first configuration information may be in one-to-one correspondence with the resource set, or in one-to-one correspondence with each resource in the resource set. Of course, it is preferable that the transmission power adjustment factor corresponding to the serving base station of the UE is equal to 0.

In this embodiment, the first configuration information may be implemented by radio resource control RRC configuration signaling. For the implementation manner that the transmission power adjustment factor corresponds to the resource set one to one, a transmission power adjustment factor field is added in the RRC configuration signaling, and the new RRC configuration signaling specifically includes:

wherein the added transmission power adjustment factor field is "power _ offset inter (-10, -5,0,5, 10)". (-10, -5,0,5,10) are candidate values for the power adjustment factor in dB, indicating that subtracting this power adjustment factor from the configured transmit power equals the final transmit power. In the actual RRC signaling sent by the base station, only one of the candidate values is indicated. At this time, a resource set is configured to the UE and sent to a target base station, and a common transmit power adjustment factor is used in one resource set.

For the implementation manner that the transmission power adjustment factor corresponds to the resource in the resource set one to one, a transmission power adjustment factor field is added in the RRC configuration signaling, and the new RRC configuration signaling specifically includes:

wherein the added transmission power adjustment factor field is "power _ offset inter (-10, -5,0,5, 10)". In this case, the UE uses multiple resources, each resource faces one target base station, different resources may use different beams, and different beams use different transmit power adjustment factors. I.e. one SRS transmission, occupies one resource set, where each resource faces a different cell.

However, the sending of the positioning SRS may be on-demand, and the first configuration information may also be implemented by a physical layer control element MAC CE signaling or a downlink control information DCI signaling, where the MAC CE or the DCI signaling may carry a sending power adjustment factor.

In addition, in this embodiment, optionally, before step 101, further including:

Here, the UE receives the second configuration information, and transmits an uplink signal to a neighboring base station of the UE using the first transmission power according to the second configuration information (including resource configuration information and a power configuration parameter (i.e., the first transmission power) of the uplink signal, where the power configuration parameter is set based on a path loss from the UE-owned base station to the UE), so that the neighboring base station can determine a corresponding transmission power adjustment factor based on the uplink signal, so that when transmitting an SRS signal, the UE uses the transmission power adjusted based on the determined transmission power adjustment factor to achieve more accurate uplink positioning. The uplink signal is not limited to the SRS signal, but may be other uplink signals, such as a physical random access PRACH signal.

The base station receiving the uplink signal can obtain the signal-to-noise ratio of the uplink signal, and then according to the signal-to-noise ratio and a preset signal-to-noise ratio threshold, the base station can calculate the transmission power adjustment factor meeting the signal-to-noise ratio threshold.

If the base station receiving the uplink signal is an adjacent base station of the UE, after the transmission power adjustment factor is determined, the base station will inform the home base station of the UE so as to inform the UE through the first configuration information; or, the sending power adjustment factor is informed to the positioning server, and the positioning server forwards the sending power adjustment factor to the home base station of the UE.

And the UE receives the first configuration information comprising the transmission power adjustment factor, so that the transmission power can be adjusted and the transmission can be optimized. Optionally, after step 101, the method further includes:

Here, when the transmission power adjustment factor is used, an offset value corresponding to the transmission power adjustment factor is increased or decreased based on the first transmission power according to a preset strategy to obtain a second transmission power, and then the SRS signal is transmitted to the neighboring base station of the UE through the second transmission power. Wherein, the relation between the transmission power adjustment factor and the offset value is as follows: the transmit power adjustment factor is an offset value, or the power adjustment factor in the signaling indication is an indication of an offset value; the product of the first transmit power and the transmit power adjustment factor is an offset value. Of course, the relation between the transmission power adjustment factor and the offset value is not limited to the above implementation and is not listed here.

Furthermore, in this embodiment, optionally, the configured resource pool is configured by the positioning server for the home base station and the neighboring base station group of the user equipment, or is generated by coordinating the home base station and the neighboring base station group, and the time domain, the frequency domain, and the cyclic shift of each resource in the configured resource pool are orthogonal to each other in the configured resource pool.

Here, the configured resource pool is common to different cell users. The configured resource pool configured by the location server LMF or the configured resource pool generated after the home base station of the UE and the adjacent base station group are coordinated, the time domain, the frequency domain and the cyclic shift of each resource in the configured resource pool are orthogonal to each other, so that the mutual interference when the resources are used is reduced. For the configured resource pool, the LMF may also configure an identity sequence ID, or the home base station and the neighboring base station group generate a sequence ID after coordination.

Preferably, the base station reserves resources in the configured resource pool by the positioning resource reservation information based on the configured resource pool, for example, performs silent muting on SRS time-frequency positions in the common resource set to reserve resources for SRS signals. The LMF sends the positioning resource reservation information to inform the base stations, or the base stations carry out the positioning resource reservation information interaction through an Xn interface.

The specific application of the method of the embodiment of the present invention is described below with reference to fig. 2:

first, the LMF informs the home base station gNB1 of the UE1 about the SRS resource configuration of the UE1 to obtain an applicable transmit power adjustment factor through testing. Then, the gNB1 notifies the UE to transmit SRS signals (uplink signals), wherein if the UE is in the beam scanning transmission mode, multiple SRS signals such as SRS1, SRS2, and SRS3 need to be transmitted; the power setting for transmitting the SRS signal is based on the path loss from the gNB1 to the UE 1. The neighboring base stations of the UE1, the gNB2 and the gNB3, estimate the transmission power adjustment factor to be used for adjustment from the received SRS signal, and the gNB2 and the gNB3 transmit the transmission power adjustment factor to the positioning server or the gNB 1. Information can be transmitted between base stations through an Xn interface. When there is a new positioning requirement, when configuring an SRS signal for a user UE, the gNB1 sends first configuration information including a first resource set and a transmission power adjustment factor corresponding to the first resource set to the UE1, and the UE1 performs SRS power adjustment based on the obtained transmission power adjustment factor, and sends the SRS signal with the adjusted power setting for positioning.

Another specific application of the method of the embodiment of the present invention is described below with reference to fig. 3:

and the LMF determines a common SRS configuration resource pool according to the number of the UE, and the SRS resources are mutually orthogonal in the configuration resource pool. The LMF notifies the managed base station groups gNB1, gNB2, and gNB3 of information on the common SRS configuration resource pool. After receiving the information of the common configuration resource pool, the base station groups gNB1, gNB2 and gNB3 will reserve these resources, and will not transmit uplink signals on the reserved resources in the base station. When the user UE1/UE2/UE3 has a positioning requirement, the LMF configures corresponding SRS resource information to respective base stations, and then the base stations transmit first configuration information including the second resource set to corresponding UEs. The UE can transmit SRS signals according to the configured SRS resources to perform positioning operation.

In summary, the method according to the embodiment of the present invention receives the first configuration information of the SRS signal, and transmits the SRS signal based on the first configuration information. If the first configuration information includes a first resource set for transmitting the SRS signal and a transmission power adjustment factor corresponding to the first resource set, the SRS signal may be transmitted by using a more suitable transmission power after the transmission power is adjusted based on the transmission power adjustment factor; if the first allocation information includes a second resource set for transmitting the SRS signal, the second resource set belongs to a preset allocation resource pool, and resources in the allocation resource pool are orthogonal to each other, and resources used for transmitting the SRS signal are orthogonal to other resources, so that interference can be reduced. In this way, the SRS signal is transmitted based on the first configuration information, and more accurate uplink positioning can be achieved.

As shown in fig. 4, a method for configuring a positioning sounding reference signal according to an embodiment of the present invention is applied to a base station, and includes:

step 401, sending first configuration information of a positioning sounding reference signal to user equipment; wherein the content of the first and second substances,

Through this step, for example, the home base station of the UE transmits the first configuration information of the SRS, so that the UE transmits the SRS signal based on the first configuration information. If the first configuration information includes a first resource set for transmitting the SRS signal and a transmission power adjustment factor corresponding to the first resource set, the SRS signal may be transmitted by using a more suitable transmission power after the transmission power is adjusted based on the transmission power adjustment factor; if the first allocation information includes a second resource set for transmitting the SRS signal, the second resource set belongs to a preset allocation resource pool, and resources in the allocation resource pool are orthogonal to each other, and resources used for transmitting the SRS signal are orthogonal to other resources, so that interference can be reduced. In this way, the SRS signal is transmitted based on the first configuration information, and more accurate uplink positioning can be achieved.

Before step 401, the method further includes:

In this way, the UE can receive the second configuration information, and transmit the uplink signal to the neighboring base station of the UE using the first transmission power based on the resource configuration information and the power configuration parameter of the uplink signal in the second configuration information, so that the neighboring base station can determine the corresponding transmission power adjustment factor based on the uplink signal, so that when transmitting the SRS signal, the UE uses the transmission power adjusted based on the determined transmission power adjustment factor to achieve more accurate uplink positioning. The uplink signal is not limited to the SRS signal, but may be other uplink signals, such as a physical random access PRACH signal.

Wherein, for a case that the first configuration information includes the second resource set, the method further comprises:

Here, after receiving the positioning resource reservation information transmitted by the positioning server or the neighboring base station of the serving UE (UE served by the base station), the base station stops transmitting the uplink signal on the resource of the configured resource pool, so as to reserve the resource for the SRS.

Optionally, the configured resource pool is configured by the positioning server for the home base station and the adjacent base station group of the user equipment, or is generated by coordinating the home base station and the adjacent base station group, and the time domain, the frequency domain, and the cyclic shift of each resource in the configured resource pool are orthogonal to each other in the configured resource pool.

It should be noted that, the method is applied to the base station, and is matched with the above-mentioned method for configuring the positioning sounding reference signal applied to the user equipment to implement the SRS configuration, and the implementation manner of the embodiment of the method for configuring the positioning sounding reference signal applied to the user equipment is applicable to the method, and can also achieve the same technical effect, and is not described herein again.

As shown in fig. 5, the method for configuring a positioning sounding reference signal according to the embodiment of the present invention is applied to a base station, and includes:

step 501, receiving a third resource set and a fourth resource set sent by a positioning server or an adjacent base station; wherein the content of the first and second substances,

Through step 501, the base station receives a third resource set and a fourth resource set sent by an adjacent base station of the LMF or the serving UE, where the third resource set is a resource set for transmitting a positioning sounding reference signal and the fourth resource set is a resource set for transmitting an interference signal, so that SRS interference is eliminated when positioning is performed based on the third resource set and the fourth resource set in the following step, and the positioning accuracy is improved. The interference signal at least comprises a positioning sounding reference signal which is not intercepted by the base station, so that the interference of the SRS which is not intercepted by the base station to the SRS intercepted by the base station is eliminated.

Of course, the interfering signal is not limited to the positioning sounding reference signal that is not intercepted by the local base station, and may also be other signals interfering with the positioning sounding reference signal that is intercepted by the local base station, which are not listed here.

It should be appreciated that the third set of resources is a set of resources relative to the base station that transmit SRS and the fourth set of resources is a set of resources relative to the base station that transmit interfering signals.

The base station is also capable of transmitting sets of resources for transmitting SRS and sets of resources for transmitting interfering signals with respect to a receiving end, which is a neighboring base station serving the UE. The base stations can exchange SRS resource sets through an Xn interface, and the SRS resource sets comprise the SRS resource sets which need to be monitored and the SRS resource sets which can cause interference of the other side and are to be informed to the other side among the base stations.

Optionally, the method further comprises:

canceling the interfering signal according to the fourth set of resources.

Thus, when the UE sends the SRS to the base station, the base station can obtain the SRS signal according to the third resource set received in step 501, and eliminate the corresponding interference signal according to the fourth resource set received in step 501, thereby improving the signal-to-noise ratio of the SRS signal.

At this time, the SRS resource used by the UE does not need to be limited, and the problem that the public configuration resource pool is short and cannot meet the requirement can be avoided.

The specific application of the method of the embodiment of the present invention is described below with reference to fig. 6:

and the LMF configures SRS resource information according to the positioning requirement of the UE. The LMF may also inform the managed base station groups of gNB1, gNB2, and gNB3 of at least two resource sets, one being a resource set to be detected by the base station (third resource set) and the other being an interfering resource set (fourth resource set). The SRS resource to be detected can be used for the UE of the cell and can also be the UE of the adjacent cell. When positioning SRS signal detection is performed by the base station groups gNB1, gNB2, and gNB3, interference cancellation is performed after obtaining an interfering SRS resource set.

The specific application of the method of the embodiment of the present invention is described below with reference to fig. 7:

the LMF configures SRS resource information according to the positioning requirement of the UE, and the base stations gNB1 and gNB2 can exchange resource sets to be detected and interference resource sets of opposite terminals through an Xn interface.

As shown in fig. 8, a method for configuring a positioning sounding reference signal according to an embodiment of the present invention is applied to a positioning server, and includes:

step 801, sending the third resource set and the fourth resource set to a home base station and/or a neighboring base station of the user equipment; wherein the content of the first and second substances,

Therefore, the base station receives a third resource set and a fourth resource set sent by the LMF, the third resource set is a resource set for transmitting the positioning sounding reference signal, and the fourth resource set is a resource set for transmitting the interference signal, so that SRS interference elimination during subsequent positioning based on the third resource set and the fourth resource set is facilitated, and the positioning accuracy is improved.

It should be noted that the method is matched with the above-mentioned method for configuring the positioning sounding reference signal applied to the base station to achieve the elimination of the positioning interference, and the embodiment of the above-mentioned method for configuring the positioning sounding reference signal applied to the base station is applicable to the method and can achieve the same technical effect.

If the first configuration information includes a first resource set for transmitting SRS signals and a transmission power adjustment factor corresponding to the first resource set, the SRS signals may be transmitted after the transmission power is adjusted based on the transmission power adjustment factor, and different power adjustment factors may correspond to different target receiving base stations, so that more applicable transmission power is used; if the first allocation information includes a second resource set for transmitting the SRS signal, the second resource set belongs to a preset allocation resource pool, and resources in the allocation resource pool are orthogonal to each other, and resources used for transmitting the SRS signal are orthogonal to other resources, so that interference can be reduced.

In this way, the SRS signal is transmitted based on the first configuration information, and more accurate uplink positioning can be achieved.
