Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an SRS configuration method, a first network device and a local management function entity. Background Art

[0002] The NR (New Radio) standard supports obtaining the terminal's positioning information by sending and receiving reference signals. For example, the OTDOA (Observed Time Difference of Arrival) positioning technology is that the terminal receives downlink reference signals sent by multiple network devices, and calculates the terminal's location information using the arrival time difference of reference signals from different network devices. The UTDOA (Uplink Time Difference of Arrival) positioning technology is that multiple network devices receive uplink reference signals sent by the terminal, and calculates the terminal's location information using the time difference when the uplink reference signals arrive at different network devices. The UL SRS (Uplink Sounding Reference Signal) in R16 can be used for air interface positioning of UE (User Equipment).

[0003] Currently, in the SRS configuration process for positioning, each network device configures an SRS for positioning for the corresponding UE and reports it to the LMF (Location Management Function). When the UE positioning is triggered, the LMF will send the configuration information of the SRS for positioning configured by the network device (serving gNB) to the serving gNB and the neighboring gNBs (neighboring base stations) / TRPs (Transmission Receive Points) selected for positioning measurement. The serving gNB and the neighboring gNBs / TRPs receive the SRS according to the configuration information. In this way, it is easy for the SRS configuration information to conflict with other uplink reference signal configuration information of the network device, that is, the SRS configuration information for positioning configured by the above-mentioned network devices for the corresponding UE is easy to cause SRS configuration information conflict.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In an embodiment of the present invention, an SRS configuration method, a repeated transmission control method and related equipment are proposed to solve the problem that in the existing repeated transmission scheme, the transmitting end cannot distinguish the number of times the target receiving end correctly demodulates the physical channel, making it difficult to reasonably adjust the number of repeated transmissions of subsequent physical channels, which easily causes a waste of physical resources.

[0053] See also Figure 1 , Figure 1 is a flowchart of an SRS configuration method provided by an embodiment of the present invention, which is used for a first terminal device, such as Figure 1 As shown, the method comprises the following steps:

[0054] Step 101: receiving a first activation signaling sent by a first network device;

[0055] Step 102: In response to the first activation signaling, activate first SRS configuration information in a sounding reference signal SRS resource pool of the first terminal device.

[0056] It can be understood that in the first terminal device, there is a corresponding SRS resource pool, and the first activation signaling is used to activate the first SRS configuration information in the SRS resource pool of the first terminal device. After receiving the first activation signaling, the first terminal device responds to the first activation signaling to activate the first SRS configuration information in the SRS resource pool of the first terminal device in the first terminal device. Each terminal device has its own corresponding SRS resource pool.

[0057] As an example, the SRS resource pool of the first terminal device may include N (N is a positive integer) SRS configuration information, and each SRS configuration information may include at least one of the following: configuration identifier (i.e., configuration ID), time domain information, frequency domain information, and code domain information. Among them, for each SRS configuration information, there is a corresponding configuration identifier, which can distinguish different SRS configuration information. The first activation signaling may include the configuration identifier of the first SRS configuration information.

[0058] In the SRS configuration method of 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, thereby reducing SRS configuration information conflicts.

[0059] 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.

[0060] That is, 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 the SRS resource pool of the first terminal device. It can be understood that the SRS resource pool of the first terminal device is 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 the available (i.e., usable) SRS configuration information configured by the first network device for the first terminal device, etc. As an example, the SRS configuration method can be applied to a positioning scenario, then the SRS resource pool of the first terminal device mentioned above is a resource pool for positioning, the second SRS configuration information is the second SRS configuration information for positioning, and the first SRS configuration information is the first SRS configuration information for positioning.

[0061] 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 based on the second SRS configuration information of the first terminal device. In this way, the conflict of SRS configuration information in the SRS resource pool can be reduced, and activating the first SRS configuration information therein can reduce the conflict of SRS configuration information.

[0062] Optionally, receiving a first activation signaling sent by a first network device includes:

[0063] The first activation signaling sent by the first network device is received after the second activation signaling sent by the local management function entity is received.

[0064] The first network device first receives a second activation signaling sent by a local management function (Location Management Function, LMF), and the second activation signaling can be used to activate the first SRS configuration information in the SRS resource pool of the first terminal device. After receiving the first activation signaling, the first network device sends the first activation signaling to the first terminal device to enable the first terminal device to activate the first SRS configuration information in the SRS resource pool of the first terminal device.

[0065] Optionally, before receiving the first activation signaling sent by the first network device, the method further includes:

[0066] Receive the SRS resource pool of the first terminal device sent by the first network device.

[0067] Before the first terminal device receives 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 is necessary to obtain the SRS resource pool of the first terminal device. In this embodiment, the first terminal device receives the SRS resource pool of the first terminal device from the first network device. It should be noted that the SRS resource pool of the first terminal device is determined based on the second SRS configuration resource of the first terminal device by the local management function entity, and the first network device can receive the SRS resource pool of the first terminal device from the local management function entity.

[0068] 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.

[0069] In the process of the local management function entity determining the SRS resource pool of the first terminal device based on the second SRS configuration resources of the first terminal device, the SRS resource pools of multiple other second terminal devices also need to be considered. The local management function entity can not only determine the SRS resource pool of the first terminal device, but also determine the SRS resource pools of multiple 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 multiple second terminal devices. In this way, it is ensured that the SRS resource pool of the first terminal device is at least partially orthogonal to the SRS resource pools of the multiple second terminal devices, thereby reducing the conflict of SRS configuration information in the SRS resource pool. It should be noted that the SRS resource pool of the second terminal device is pre-configured, 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. The difference is that the terminal devices are different and the second SRS configuration resources of the terminal devices are different.

[0070] Optionally, the first SRS configuration information is orthogonal to currently activated SRS configuration information of multiple second terminal devices.

[0071] Since the subsequent first terminal device needs to transmit SRS through the activated first SRS configuration information to improve the performance of the transmitted SRS, it is necessary to reduce the conflict of the activated first SRS configuration as much as possible. Therefore, in this embodiment, the first SRS configuration information is required to be orthogonal to the currently activated SRS configuration information of multiple second terminal devices, so as to avoid the conflict between the first SRS configuration information and the currently activated SRS configuration information of multiple second terminal devices, thereby improving the reliability of the subsequent transmission of the corresponding SRS.

[0072] See also Figure 2 , Figure 2 is a flowchart of an SRS configuration method provided by an embodiment of the present invention, which is used for a first network device, such as Figure 2 As shown, the method comprises the following steps:

[0073] Step 201: receiving a second activation signaling sent by a local management function entity;

[0074] The second activation signaling is used to activate the first sounding reference signal SRS configuration information, where the first SRS configuration information is SRS configuration information in an SRS resource pool of the first terminal device;

[0075] Step 202: In response to the second activation signaling, a first activation signaling is sent to the first terminal device.

[0076] The first activation signaling is used to activate the first SRS configuration information in the SRS resource pool of the first terminal device.

[0077] The first network device first receives the second activation signaling sent by 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.

[0078] In the SRS configuration method of 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 to activate the first SRS configuration information in the SRS resource pool of the first terminal device. Subsequently, the first terminal device can transmit SRS based on the activated first SRS configuration information, thereby reducing SRS configuration information conflicts.

[0079] 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.

[0080] 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 to activate the first SRS configuration information in the SRS resource pool of the first terminal device. Subsequently, the first terminal device can transmit SRS based on the activated first SRS configuration information, and the SRS resource pool of the first terminal device is SRS configuration information determined according to the second SRS configuration information of the first terminal device. In this way, the conflict of SRS configuration information in the SRS resource pool can be reduced, and the first SRS configuration information therein can be activated to reduce the conflict of SRS configuration information.

[0081] As an example, the first network device may send the first activation signaling to the first terminal device via MAC CE (Media Access Control Control Element) signaling.

[0082] Optionally, before receiving the second activation signaling sent by the local management function entity, the method further includes:

[0083] Receiving a first request sent by a local management function entity;

[0084] In response to the first request, second SRS configuration information is sent to the local management function entity.

[0085] That is, the second SRS configuration information of the first terminal device is configured by the first network device. The second SRS configuration information can be understood as the available SRS configuration information configured by the first network device for the first terminal device. First, the first network device needs to receive a first request sent by the local management function entity, that is, the local management function entity needs to send a first request to the first network device to request the SRS configuration information of the first terminal device. After the first network device is configured to receive the first request, it can determine the second SRS configuration information and send it to the local management function entity. Subsequently, the local management function entity can determine the SRS resource pool of the first terminal device based on the second SRS configuration information.

[0086] Optionally, the first request includes third SRS configuration information;

[0087] In response to the first request, sending second SRS configuration information to the first network device includes:

[0088] Determine second SRS configuration information based on the third SRS configuration information;

[0089] Send the second SRS configuration information to the local management function entity.

[0090] The third SRS configuration information can be understood as the SRS configuration information recommended by the local management function entity to the first network device for the first terminal device. The first network device can 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 can be the recommended SRS configuration information determined by the local management function entity based on the positioning accuracy requirement of the first terminal device. The second SRS configuration information can include part or all of the third SRS configuration information, or may not include the third SRS configuration information.

[0091] Optionally, after sending the second SRS configuration information to the local management function entity, the method further includes:

[0092] Receive an SRS resource pool of a first terminal device sent by a local management function entity;

[0093] Send the SRS resource pool of the first terminal device to the first terminal device.

[0094] That is, the first network device receives the SRS resource pool of the first terminal device sent by the local management function entity, and sends it to the first terminal device. In this way, the first terminal device can obtain the SRS resource pool of the first terminal device, so that after subsequently receiving the first activation signaling, it can activate the first SRS configuration information from the SRS resource pool of the first terminal device, so as to subsequently transmit the SRS.

[0095] As an example, the first network device may send the SRS resource pool of the first terminal device to the first terminal device via RRC (Radio Resource Control) signaling.

[0096] 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.

[0097] Optionally, the first SRS configuration information is orthogonal to currently activated SRS configuration information of multiple second terminal devices.

[0098] See also Figure 3 , Figure 3 is a flowchart of an SRS configuration method provided by an embodiment of the present invention, which is used for local management function entities, such as Figure 3 As shown, the method comprises the following steps:

[0099] Step 301: receiving a positioning request for a first terminal device;

[0100] Step 302: In response to the positioning request, send a second activation signaling to the first network device, where the second activation signaling is used to activate the first sounding reference signal SRS configuration information;

[0101] The first SRS configuration information is SRS configuration information in the SRS resource pool of the first terminal device.

[0102] There are many ways to trigger a positioning request, which are not limited in this embodiment. For example, it can be triggered by the first terminal device, triggered by a network element in the core network, or triggered by the core network. These three triggering methods all involve sending a positioning request for the device on the first terminal to the local management function entity through the core network (that is, the positioning request is used to request the positioning of the first terminal device). The local management function entity can receive the positioning request sent by the core network. After receiving the positioning request for the first terminal device, the local management function entity can send a second activation signaling to the first network device. In response to the second activation signaling, the first network device sends a 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 after receiving the first activation signaling.

[0103] In the SRS configuration method of this embodiment, after the local management function entity receives the positioning request for the first terminal device, it sends a second activation signaling to the first network device to activate the first SRS configuration information in the SRS resource pool of the first terminal device, thereby reducing SRS configuration information conflicts.

[0104] 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.

[0105] In this embodiment, after the local management function entity receives the positioning request for the first terminal device, it sends a second activation signaling to the first network device, which can activate the first SRS configuration information in the SRS resource pool of the first terminal device. Moreover, the SRS resource pool of the first terminal device is the SRS configuration information determined based on the second SRS configuration information of the first terminal device. In this way, the conflict of SRS configuration information in the SRS resource pool can be reduced, and activating the first SRS configuration information therein can reduce the conflict of SRS configuration information.

[0106] Optionally, before sending the second activation signaling to the first network device in response to the positioning request, the method further includes:

[0107] Sending a first request to a first network device;

[0108] Receiving second SRS configuration information sent by the first network device in response to the first request;

[0109] Based on the second SRS configuration information, an SRS resource pool of the first terminal device is determined.

[0110] Optionally, after determining the SRS resource pool of the first terminal device, the method further includes:

[0111] The SRS resource pool of the first terminal device is sent to the first network device.

[0112] Optionally, after receiving the positioning request for the first terminal device, the method further includes:

[0113] In response to the positioning request, first SRS configuration information is sent to a plurality of second network devices.

[0114] That is, the local management function entity can not only 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 to realize the activation of the first SRS configuration information in the SRS resource pool of the first terminal device, but also send the first SRS configuration information to multiple second network devices to notify multiple second network devices that the first terminal device activates the first SRS configuration information, and subsequently the first terminal device transmits SRS based on the activated first SRS configuration information. Based on the activated first SRS configuration information, multiple second network devices can configure the corresponding SRS configuration information for other terminal devices (within the coverage of the second network device) based on the activated first SRS configuration information to reduce SRS configuration conflicts. It should be noted that the above-mentioned multiple second network devices are multiple network devices adjacent to the first network device.

[0115] 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.

[0116] Optionally, the first SRS configuration information is orthogonal to currently activated SRS configuration information of multiple second terminal devices.

[0117] The process of the above SRS configuration method is specifically described below with a specific embodiment. The first network device is a serving gNB, the second network device is a base station adjacent to the serving gNB, i.e., a neighboring gNB or a transmission receiving point (TRP) adjacent to the serving gNB, the first terminal device is a first UE (User Equipment), and the second terminal device is a second UE.

[0118] The LMF requests the SRS configuration information of the first UE from the serving gNB, and carries the recommended SRS configuration information, i.e., the third SRS configuration information.

[0119] The specific content of the third SRS configuration information may include the content shown in Table 1.

[0120] Table 1

[0121]

[0122]

[0123] Number Of Transmissions / duration for which the UL-SRS is requested can be understood as the number of uplink transmission SRSs, Bandwidth is the bandwidth, Resource type is the resource type, for example, it can be periodic or semi-persistent, etc. Pathloss reference is the path loss reference information, which can include PCI, SSBindex and SSB configuration (time / frequency occupancy of SSBs), as well as DL-PRS ID, DL-PRS Resource Set ID, DL-PRS Resource ID. Spatial relation info is the spatial relationship information, which can also include PCI, SSBindex and SSB configuration (time / frequency occupancy of SSBs), as well as DL-PRS ID, DL-PRS Resource Set ID, DL-PRS Resource ID.

[0124] Among them, PCI is Physical Cell Identifier, and its Chinese name is physical cell identifier. 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), etc. DL-PRS ID is downlink positioning reference signal identifier, DL-PRS Resource Set ID is downlink positioning reference signal resource set identifier, and DL-PRSResource ID is downlink positioning reference signal resource identifier.

[0125] The serving gNB refers to the SRS configuration recommended by the LMF and reports the available SRS configuration information (second SRS configuration information) of the first UE to the LMF. The available SRS configuration information can be understood as the available SRS configuration information of the first UE.

[0126] LMF can configure an SRS resource pool for positioning for each UE it manages, and feed back the SRS resource pool to the serving gNB corresponding to the UE (i.e. the gNB to which the UE is connected). It should be noted that the principle of LMF configuring the SRS resource pool is to configure the corresponding SRS configuration information for the UE in the available SRS configuration reported by the serving gNB according to the positioning accuracy requirements of each UE (such as the density required by SRS in the time domain), and the SRS resource pools of each UE are as orthogonal as possible to avoid SRS configuration collisions affecting measurement accuracy.

[0127] The serving gNB sends the resource pool information of the first UE used for positioning configured by the LMF to the first UE (e.g., through RRC signaling).

[0128] When a positioning request for the first UE is triggered, the LMF sends a second activation signaling to the first network device. After receiving the second activation signaling, the first network device sends a first activation signaling to the first UE. After receiving the first activation signaling, the first UE activates an SRS configuration information from the resource pool of the first UE, that is, 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 devices, avoiding SRS pumping, so that the first UE can subsequently implement SRS uplink transmission based on the activated first SRS configuration information, thereby improving the uplink transmission performance.

[0129] For example, there are three cells, assuming that each cell has one UE, namely UE1, UE2, and UE3. The SRS resource pool of each UE includes two SRS configurations. The SRS resource pool of UE1 is configured as config1 and config2, the SRS resource pool of UE2 is configured as config3 and config4, and the SRS resource pool of UE3 is configured as config5 and config6. Among them, config1 and config3 are orthogonal, and config2 and config5 are orthogonal. When both UE1 and UE2 are triggered to request for positioning, config1 of UE1 and config3 of UE2 can be activated. When both UE1 and UE3 are triggered to request for positioning, config2 of UE1 and config5 of UE3 can be activated to ensure that the SRS configurations of the currently activated UEs are orthogonal to reduce SRS conflicts.

[0130] The embodiment of the present application provides an SRS configuration method that can reduce SRS configuration conflicts. Since the LMF has global SRS configuration information for positioning, the LMF can decide the SRS configuration of each base station to avoid conflicts as much as possible. The LMF can configure the SRS resource pool of the UE. When the positioning request is triggered, an SRS configuration that avoids conflicts as much as possible is activated from the SRS resource pool of the UE according to the uplink transmission of the UE's serving gNB and neighboring gNBs / TRPs.

[0131] like Figure 4 As shown, an embodiment of the present invention further provides a first terminal device 400, and the first terminal device 400 includes:

[0132] The first receiving module 401 is used to receive a first activation signaling sent by a first network device;

[0133] The activation module 402 is used to activate first SRS configuration information in a sounding reference signal SRS resource pool of a first terminal device in response to a first activation signaling, wherein the first SRS configuration information is a piece of SRS configuration information in the SRS resource pool.

[0134] 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.
