All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the invention, an SRS configuration method, a repeated transmission control method and related equipment are provided to solve the problem that a sending end cannot distinguish the times of correctly demodulating a physical channel by a target receiving end in the existing repeated transmission scheme, so that the repeated transmission times of subsequent physical channels are difficult to reasonably adjust, and further physical resources are easily wasted.

Referring to fig. 1, fig. 1 is a flowchart of an SRS configuration method provided in an embodiment of the present invention, where the SRS configuration method is used for a first terminal device, and as shown in fig. 1, the method includes the following steps:

step 101: receiving a first activation signaling sent by first network equipment;

step 102: and responding to the first activation signaling, and activating first SRS configuration information in a sounding reference signal SRS resource pool of the first terminal equipment.

It can be understood that, in the first terminal device, the SRS resource pool corresponding to the first terminal device is provided, the first activation signaling is used to activate the first SRS configuration information in the SRS resource pool of the first terminal device, and after receiving the first activation signaling, the first terminal device responds to the first activation signaling, so that the first SRS configuration information in the SRS resource pool of the first terminal device in the first terminal device can be activated. Each terminal device has a corresponding SRS resource pool.

As an example, N (N is a positive integer) SRS configuration information may be included in the SRS resource pool of the first terminal device, and each SRS configuration information may include at least one of: configuration identification (i.e., configuration ID), time domain information, frequency domain information, code domain information. And for each SRS configuration information, corresponding configuration identification is respectively provided, and different SRS configuration information can be distinguished. The first activation signaling may include a configuration identifier of the first SRS configuration information.

Optionally, the SRS resource pool of the first terminal device is SRS configuration information determined based on the second SRS configuration information of the first terminal device.

I.e. the SRS resource pool of the first terminal device may be configuration information determined by the second SRS configuration information of the first terminal device. It should be noted that the second SRS configuration information of the first terminal device includes an SRS resource pool of the first terminal device, and it can be understood that the SRS resource pool of the first terminal device is a part or all of the second SRS configuration information of the first terminal device. The second SRS configuration information of the first terminal device may be available (i.e. usable) SRS configuration information or the like configured by the first network device for the first terminal device. As an example, the SRS configuration method may be applied to a positioning scenario, where the SRS resource pool of the first terminal device is a resource pool for positioning, the second SRS configuration information is second SRS configuration information for positioning, and the first SRS configuration information is first SRS configuration information for positioning.

In this embodiment, after receiving the first activation signaling sent by the first network device, the first terminal device activates the first SRS configuration information from the SRS resource pool of the first terminal device, and the SRS resource pool of the first terminal device is the SRS configuration information determined according to the second SRS configuration information of the first terminal device, so that the SRS configuration information collision in the SRS resource pool can be reduced, and the first SRS configuration information is activated, so that the SRS configuration information collision can be reduced.

Optionally, receiving the first activation signaling sent by the first network device includes:

and receiving a first activation signaling sent by the first network equipment after receiving a second activation signaling sent by the local management function entity.

The first network device first receives a second activation signaling sent by a Local Management Function (LMF), where the second activation signaling may be used to activate first SRS configuration information in an SRS resource pool of the first terminal device, and after receiving the first activation signaling, the first network device sends the first activation signaling to the first terminal device, so that the first terminal device activates the first SRS configuration information in the SRS resource pool of the first terminal device.

Optionally, before receiving the first activation signaling sent by the first network device, the method further includes:

and receiving the SRS resource pool of the first terminal equipment sent by the first network equipment.

In this embodiment, the first terminal device receives the SRS resource pool of the first terminal device from the first network device before receiving the first activation signaling sent by the first network device to activate the first SRS configuration information in the SRS resource pool of the first terminal device. It should be noted that, by determining, by the local management function entity, the SRS resource pool of the first terminal device based on the second SRS configuration resource of the first terminal device, the first network device may receive the SRS resource pool of the first terminal device from the local management function entity.

Optionally, the SRS resource pool of the first terminal device is at least partially orthogonal to the SRS resource pools of the plurality of second terminal devices.

In the process of determining the SRS resource pool of the first terminal device by the local management function entity based on the second SRS configuration resource of the first terminal device, the SRS resource pools of other second terminal devices need to be considered, the local management function entity can determine not only the SRS resource pool of the first terminal device but also the SRS resource pools of the second terminal devices, and the SRS resource pool of the first terminal device is at least partially orthogonal to the SRS resource pools of the second terminal devices, so as to ensure that the SRS resource pool of the first terminal device is at least partially orthogonal to the SRS resource pools of the second terminal devices, thereby reducing the SRS configuration information collision in the SRS resource pools. It should be noted that the SRS resource pool of the second terminal device is configured in advance, and the process of configuring the SRS resource pool of the second terminal device is similar to the process of determining the SRS resource pool of the first terminal device, but the difference is that the terminal devices are different, and the second SRS configuration resource of the terminal device is different.

Optionally, the first SRS configuration information is orthogonal to currently activated SRS configuration information of the plurality of second terminal devices.

Since the subsequent first terminal device needs to transmit the SRS through the activated first SRS configuration information to improve the performance of transmitting the SRS, and the collision of the activated first SRS configuration needs to be reduced as much as possible, in this embodiment, the first SRS configuration information is required to be orthogonal to the currently activated SRS configuration information of the plurality of second terminal devices, so that the collision of the first SRS configuration information and the currently activated SRS configuration information of the plurality of second terminal devices can be avoided, and the reliability of the subsequent transmission of the corresponding SRS can be improved.

Referring to fig. 2, fig. 2 is a flowchart of an SRS configuration method provided in an embodiment of the present invention, where the SRS configuration method is used for a first network device, and as shown in fig. 2, the method includes the following steps:

step 202: and responding to the second activation signaling, and sending the first activation signaling to the first terminal equipment.

The first activation signaling is used for activating first SRS configuration information in an SRS resource pool of the first terminal device.

The first network device firstly receives the second activation signaling from the local management function entity, and then sends the first activation signaling to the first terminal device, so that the first terminal device activates the first SRS configuration information in the SRS resource pool of the first terminal device.

Optionally, the SRS resource pool of the first terminal device is SRS configuration information determined based on the second SRS configuration information of the first terminal device. The first network device may receive the SRS resource pool of the first terminal device from the local management function entity.

In this embodiment, after receiving the second activation signaling sent by the local management function entity, the first network device sends the first activation signaling to the first terminal device, so as to activate the first SRS configuration information in the SRS resource pool of the first terminal device, and the subsequent first terminal device may transmit the SRS based on the activated first SRS configuration information, and the SRS resource pool of the first terminal device is the SRS configuration information determined according to the second SRS configuration information of the first terminal device, so that the SRS configuration information collision in the SRS resource pool can be reduced, the first SRS configuration information in the SRS configuration pool is activated, and the SRS configuration information collision can be reduced.

As an example, the first network device may send the first activation signaling to the first terminal device through a MAC CE (Media Access Control Element) signaling.

Optionally, before receiving the second activation signaling sent by the local management function entity, the method further includes:

receiving a first request sent by a local management function entity;

and responding to the first request, and transmitting second SRS configuration information to the local management function entity.

That is, the first network device configures the second SRS configuration information of the first terminal device, and the second SRS configuration information may be understood as available SRS configuration information configured for the first terminal device by the first network device. First, a first network device needs to receive a first request sent by the first network device from a local management function entity, that is, the local management function entity needs to send the first request to the first network device for requesting SRS configuration information of a first terminal device, after the first network device receives the first request by configuration, second SRS configuration information can be determined and sent to the local management function entity, and a subsequent local management function entity can determine an SRS resource pool of the first terminal device based on the second SRS configuration information.

Optionally, the first request includes third SRS configuration information;

in response to the first request, transmitting second SRS configuration information to the first network device, including:

determining second SRS configuration information based on the third SRS configuration information;

and sending the second SRS configuration information to the local management function entity.

The third SRS configuration information may be understood as SRS configuration information recommended by the local management function entity to the first network device for the first terminal device, and the first network device may refer to the SRS configuration information recommended by the local management function entity and report the second SRS configuration information to the local management function entity. As an example, the third SRS configuration information may be recommended SRS configuration information determined by the local management function entity according to the positioning accuracy requirement of the first terminal device, and the second SRS configuration information may include part or all of the third SRS configuration information, or may not include the third SRS configuration information.

Optionally, after sending the second SRS configuration information to the local management function entity, the method further includes:

receiving an SRS resource pool of first terminal equipment sent by a local management function entity;

and sending the SRS resource pool of the first terminal equipment to the first terminal equipment.

That is, the first network device receives, from the local management function entity, the SRS resource pool of the first terminal device that is sent by the first network device, and sends the SRS resource pool of the first terminal device to the first terminal device, so that the first terminal device can obtain the SRS resource pool of the first terminal device, so as to activate, after receiving the first activation signaling, the first SRS configuration information from the SRS resource pool of the first terminal device, so as to transmit the SRS subsequently.

As an example, the first network device may send, to the first terminal device, an SRS Resource pool of the first terminal device through RRC (Radio Resource Control) signaling.

Referring to fig. 3, fig. 3 is a flowchart of an SRS configuration method provided in an embodiment of the present invention, where the SRS configuration method is used for a local management function entity, and as shown in fig. 3, the method includes the following steps:

step 301: receiving a positioning request aiming at a first terminal device;

step 302: responding to the positioning request, and sending a second activation signaling to the first network equipment, wherein the second activation signaling is used for activating the SRS configuration information of the first sounding reference signal;

There are various ways to trigger the location request, which is not limited in this embodiment, for example, the triggering may be triggering of the first terminal device, triggering of a network element in the core network, or triggering of the core network, where the three triggering ways are all that the core network sends a location request for a device on the first terminal to the local management functional entity (that is, the location request is used to request location of the first terminal device), and the local management functional entity may receive the location request sent by the core network. The local management function entity may send a second activation signaling to the first network device after receiving the positioning request for the first terminal device, and the first network device sends the first activation signaling to the first terminal device in response to the second activation signaling, so that the first terminal device activates the first SRS configuration information in the SRS resource pool of the first terminal device after receiving the first activation signaling.

In the SRS configuration method of this embodiment, after receiving the positioning request for the first terminal device, the local management function entity sends the second activation signaling to the first network device, and may activate the first SRS configuration information in the SRS resource pool of the first terminal device, so that SRS configuration information collision may be reduced.

Optionally, the SRS resource pool is SRS configuration information determined by the local management function entity based on the second SRS configuration information of the first terminal device.

In this embodiment, after receiving the positioning request for the first terminal device, the local management function entity sends a second activation signaling to the first network device, which may activate the first SRS configuration information in the SRS resource pool of the first terminal device, and the SRS resource pool of the first terminal device is the SRS configuration information determined according to the second SRS configuration information of the first terminal device, so that the SRS configuration information collision in the SRS resource pool may be reduced, the first SRS configuration information in the SRS resource pool is activated, and the SRS configuration information collision may be reduced.

Optionally, before sending the second activation signaling to the first network device in response to the positioning request, the method further includes:

sending a first request to a first network device;

receiving second SRS configuration information sent by the first network equipment in response to the first request;

and determining the SRS resource pool of the first terminal equipment based on the second SRS configuration information.

Optionally, after determining the SRS resource pool of the first terminal device, the method further includes:

and sending the SRS resource pool of the first terminal equipment to the first network equipment.

Optionally, after receiving the positioning request for the first terminal device, the method further includes:

in response to the positioning request, first SRS configuration information is transmitted to a plurality of second network devices.

That is, the local management function entity may send the resource pool of the first terminal device to the first terminal device through the first network device, and send the second activation signaling to the first network device, so as to implement activation of the first SRS configuration information in the SRS resource pool of the first terminal device, and may send the first SRS configuration information to the plurality of second network devices, so as to notify the plurality of second network devices, where the first SRS configuration information is activated by the first terminal device, the subsequent first terminal device transmits the SRS based on the activated first SRS configuration information, the plurality of second network devices configure the SRS configuration information of the response for the other terminal devices (in the coverage of the second network devices) based on the activated first SRS configuration information, so as to reduce SRS configuration conflicts. The plurality of second network devices are a plurality of network devices adjacent to the first network device.

The procedure of the SRS configuration method is described in detail below with an embodiment. The first network device is a serving base station (serving gbb), the second network device is a base station adjacent to the serving base station, that is, a neighbor base station (neighbor gbb), or a Transmission Receive Point (TRP) adjacent to the serving base station, the first terminal device is a first UE (User Equipment), and the second terminal device is a second UE.

The LMF requests SRS configuration information of the first UE from the serving gNB and carries recommended SRS configuration information, namely third SRS configuration information.

Specific contents of the third SRS configuration information may include contents as in table 1.

TABLE 1

The Number Of Transmissions/duration for the UL-SRS is requested may be understood as the Number Of uplink SRS transmission, Bandwidth, Resource type, for example, the Resource type may be periodic or semi-persistent. The Pathloss reference is the road loss reference information, which may include PCI, SSBindex and SSB configuration (time/frequency allocation of SSBs), and DL-PRS ID, DL-PRS Resource Set ID, DL-PRS Resource ID. The Spatial relationship information may also include PCI, SSBindex and SSB configuration (time/frequency allocation of SSBs), and DL-PRS ID, DL-PRS Resource Set ID, DL-PRS Resource ID.

The PCI is Physical Cell Identifier, the chinese name is Physical Cell Identifier, and the SSB index is SSB (Synchronization Signal and PBCH block) index. SSB configuration is SSB configuration information, which may include SSB time domain information (time)/frequency domain information (frequency), and the like. DL-PRS ID is the identification of the downlink positioning reference signal, DL-PRS Resource Set ID is the identification of the downlink positioning reference signal Resource Set, and DL-PRS Resource ID is the identification of the downlink positioning reference signal Resource.

The serving gbb refers to the SRS configuration recommended by the LMF, and reports available SRS configuration information (second SRS configuration information) of the first UE to the LMF, where the available SRS configuration information can be understood as available SRS configuration information of the first UE.

The LMF may configure an SRS resource pool for positioning for each UE it manages, and feed back the SRS resource pool to the UE's corresponding serving gbb (i.e., the gbb to which the UE is connected). It should be noted that, the principle of configuring the SRS resource pool by the LMF is to configure, in the available SRS configuration reported by the serving gbb, corresponding SRS configuration information for the UE according to the positioning accuracy requirement (e.g., the SRS required density in the time domain) of each UE, and the SRS resource pools of the UEs are orthogonal as much as possible, so as to avoid that the SRS configuration collision affects the measurement accuracy.

The serving gNB issues the resource pool information of the first UE configured by the LMF for positioning to the first UE (e.g., through RRC signaling).

When a positioning request for a first UE is triggered, an LMF sends a second activation signaling to the first network equipment, the first network equipment sends a first activation signaling to the first UE after receiving the second activation signaling, the first UE activates an SRS configuration information from a resource pool of the first UE, namely activates the first SRS configuration information, the activated first SRS configuration information is orthogonal to the SRS configuration information currently activated by other second terminal equipment, SRS pump installation is avoided, and therefore the subsequent first UE can realize uplink transmission of the SRS based on the activated first SRS configuration information, and uplink transmission performance can be improved.

For example, there are three cells (cells), and it is assumed that there are 1 UEs per cell, namely UE1, UE2, and UE 3. The SRS resource pool of each UE includes two SRS configurations. The SRS resource pool of the UE1 is configured as config1 and config2, the SRS resource pool of the UE2 is configured as config3 and config4, and the SRS resource pool of the UE3 is configured as config5 and config 6. Wherein config1 and config3 are orthogonal, and config2 and config5 are orthogonal. When both the UE1 and the UE2 are triggered to make positioning requests, the config1 of the UE1 and the config3 of the UE2 may be activated, and when both the UE1 and the UE3 are triggered to make positioning requests, the config2 of the UE1 and the config5 of the UE3 may be activated to ensure that the SRS configurations of currently activated UEs are orthogonal to reduce SRS collisions.

The embodiment of the application provides an SRS configuration mode capable of reducing SRS configuration conflicts. Because the LMF has global SRS configuration information for positioning, the LMF can decide the SRS configuration of each base station, and the occurrence of conflict is avoided as much as possible. The LMF can configure the SRS resource pool of the UE, and when a positioning request is triggered, one SRS configuration which avoids conflict as much as possible is activated from the SRS resource pool of the UE according to the uplink transmission conditions of the serving gNB and the neighbor gNBs/TRPs of the UE.
