Description

Configuration method, device and storage medium of transmission receiving node

Technical Field

The present application relates to the field of communications, and in particular, to a method and apparatus for configuring a transmitting and receiving node, and a storage medium.

Background

In a communication system, a base station covers a plurality of cells (also called cells), and in order to improve communication quality, a terminal can be handed over from one cell to another cell with higher signal quality.

When switching cells for a terminal, the handover is typically initiated by the source cell. Specifically, the source cell determines that the terminal needs to be switched to the target cell based on a measurement result reported by the terminal, and sends a radio resource control (Radio Resource Control, RRC) reconfiguration message to the terminal; and the terminal is switched from the source cell to the target cell after receiving the RRC reconfiguration message. However, the process of switching cells may cause service interruption of the terminal and a decrease in data transmission rate, which may further cause poor communication effect of the terminal.

step 1, switching measurement and report are carried out between a terminal and a source cell; step 2, the source cell makes a switching decision based on the measurement result; step 3, the source cell sends a handover request to the target cell; step 4, the target cell performs admission control (Admission Control) based on the handover request of the source cell; step 5, after the target cell prepares for the cell switching of the terminal, the target cell can return a confirmation message of the handover request to the source cell; step 6, the source cell can respond to the switching message and instruct the terminal to switch cells; step 7, the source cell transmits cached or data from UPF related to the terminal to the target cell; step 8, the terminal releases the dependence (i.e. the detachment) of the source cell and performs the synchronization with the target cell; and 9, the cell switching is successful, namely the terminal is successfully switched from the source cell to the target cell.

In step 6, the source cell needs to send an RRC reconfiguration message to the terminal. The RRC reconfiguration message includes: the related information of the target cell and the related information (such as random access parameters) for the terminal to access the target cell. Step 9 comprises the following two processes: a random access process between the terminal and the target cell and a process of the terminal sending an RRC reconfiguration complete message corresponding to the RRC reconfiguration message to the target cell. After the terminal receives the RRC reconfiguration message and determines to switch to the target cell (step 6), the terminal disconnects from the source cell and initiates synchronization to the target cell. It can be seen that, in the cell handover process of the terminal, the data transmission of the terminal is interrupted, resulting in poor communication effect of the terminal.

In summary, cell switching of the terminal may bring service interruption and a decrease in data transmission rate, and a manner that the cells are fixedly disposed and are generally disposed under one DU may further cause frequent cell switching when the terminal moves in position and changes in service, which further results in poor communication effect of the terminal.

In order to solve the above-mentioned problems, embodiments of the present application provide a method, an apparatus and a storage medium for configuring a transmission receiving node, wherein one or more TRPs are dynamically organized by DUs based on reporting information of a terminal to provide data transmission services for the terminal, the one or more TRPs of the dynamic organization form a virtual cell for the terminal, wherein the one or more TRPs of the dynamic organization (i.e., TRPs in the virtual cell) may belong to one or more DUs. Therefore, compared with the scheme that the cells are fixedly deployed and can only be deployed under one DU, the embodiment of the application can dynamically deploy the cells for the terminal under one or more DUs, particularly can provide transmission services for the terminal among different DUs, reduces the cell switching of the terminal and improves the communication effect of the terminal.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Based on the technical conception, the application scene of the embodiment of the application is as follows:

fig. 3 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 3, the present embodiment provides a communication system including a network device 110 and terminals 120 (fig. 3 illustrates 2 terminals 120), wherein the network device 110 includes CUs, DUs, and TRPs, and wherein one CU can control a plurality of DUs (fig. 3 illustrates CU control DUs 1 and DUs 2), and one DU can control a plurality of TRPs. One or more TRPs may be flexibly organized under one or more DUs as the location movement and/or traffic demand of the terminal 120 changes, with the one or more TRPs dynamically forming a virtual cell for the terminal 120, the TRPs in the virtual cell providing a transmission service for the terminal 120. The TRP in the virtual cell may be located in the same DU, or may span the DU, and fig. 3 illustrates that the virtual cell spans DU1 and DU 2. Therefore, the TRP is dynamically configured by adapting to the position movement and/or service demand change of the terminal, so that the dynamic and flexible deployment of the cell is realized, and the communication effect of the terminal is improved.

The following describes a configuration method of a transmission receiving node according to an embodiment of the present application with reference to fig. 4 to fig. 9 in conjunction with the application scenario of fig. 3. It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present application, and the embodiment of the present application may also be applied to any scenario where applicable.

In order to facilitate the understanding of the following examples, some terms related to the embodiments of the present application will be explained in detail as follows:

virtual cell: also referred to as a flexible cell, is a cell formed by dynamically configuring TRPs under one or more DUs. Wherein, the TRP in the virtual cell is not fixed, and is adapted to the change of the reported information of the terminal, and the TRP in the virtual cell also changes.

First DU, second DU: the first DU refers to a DU located in a cell in which the terminal is currently located, in other words, the first DU is a DU to which the terminal is currently connected, so the first DU may also be referred to as a source DU or a main DU. Conversely, the second DU refers to a DU not located in the cell where the terminal is currently located. Wherein, an interface can be established between the first DU and the second DU, in other words, the information coordination can be performed between the first DU and the second DU through the established interface. The interface between the first DU and the second DU may be pre-established, or may be established when the first DU and the second DU need to cooperate with each other.

Optionally, the first DU and the second DU are subordinate to the same CU. Thus, a virtual cell dynamically configured for a terminal between different DUs under the same CU can be implemented.

Fig. 4 is a schematic flow chart of a configuration method of a transmitting and receiving node according to an embodiment of the present application, where the method is applied to DUs, and the DUs may be a first DU and/or a second DU. As shown in fig. 4, the configuration method of the transmission receiving node of the present embodiment may include:

s401, the DU acquires first configuration information of the TRP group, and the first configuration information is generated when it is determined that the terminal forms the TRP group of the virtual cell based on the reported information of the terminal.

The reported information of the terminal comprises the terminal position and/or the terminal service requirement. The terminal position can be obtained by the terminal through a positioning system, and the terminal service requirement such as the high reliability and low delay requirement of the ultra-reliable low delay communication service on the communication signal is met. Therefore, the method is suitable for the terminal position and/or the terminal service requirement, and a proper TRP group is dynamically configured for the terminal, namely a proper virtual cell is dynamically configured for the terminal, so that the virtual cell can meet the communication requirement of the terminal after the position is moved and/or after the requirement is changed.

Wherein the TRP group comprises one or more TRPs, which may be subordinate to one or more DUs. In particular, the TRP group may comprise TRPs connected to the first DU (i.e. TRPs subordinate to the first DU) and/or TRPs connected to the second DU (i.e. TRPs subordinate to the second DU).

Wherein the first configuration information may include configuration information related to the first DU and/or configuration information related to the second DU. Further, the configuration information associated with the first DU may include at least one of: an identification of a TRP in the TRP group that is connected to the first DU, one or more resources associated with the TRP in the TRP group that is connected to the first DU; the configuration information associated with the second DU may be at least one of: the identification of the TRP in the TRP group to which the second DU is connected, one or more resources associated with the second DU, one or more resources associated with the TRP in the TRP group to which the second DU is connected. Thus, TRP is accurately and flexibly activated with these contents based on the first configuration information, thereby improving flexibility and accuracy of the virtual cell.

In this embodiment, the TRP group forming the virtual cell for the terminal may be determined on any network device of the DU, the CU connected to the DU, and the other DU that establishes an interface with the DU, in response to the report information of the terminal, and the first configuration information of the TRP group may be determined. Therefore, the DU may determine TRP groups forming a virtual cell for the terminal in response to the reported information of the terminal and determine first configuration information of the TRP groups, or the DU may receive the first configuration information from the CU and/or other DUs.

Optionally, if the DU determines that the terminal forms the TRP group of the virtual cell based on the reported information of the terminal, the terminal may periodically send the reported information to the DU; or, the terminal may send reporting information to the DU when the location changes and/or the service requirements change; alternatively, the terminal may send the report information to the DU when receiving a request for the DU to acquire the report information.

Optionally, if the TRP group forming the virtual cell for the terminal is determined on the DU based on the reported information of the terminal, the DU may autonomously monitor or receive the reported information of the terminal. Further, the MAC layer or the physical layer of the DU may autonomously monitor or receive the report information of the terminal.

S402, the DU activates the TRP connected with the DU in the TRP group according to the first configuration information.

Wherein, activating the TRP refers to configuring the TRP to an active state (or referred to as an operating state) in which the TRP can provide a communication service for the terminal.

In this embodiment, in the case that the TRP group includes the TRP connected to the DU, the DU may activate the TRP connected to the DU in the TRP group according to the configuration information related to the DU in the first configuration information. Specifically, in the case that the TRP group only includes the TRP connected to the first DU, the first DU may activate the TRP connected to the first DU in the TRP group according to the configuration information (such as the identification of the TRP connected to the first DU) related to the first DU by the first configuration information; alternatively, in the case where the TRP group includes a TRP connected to the first DU and a TRP connected to the second DU, the first DU may activate the TRP connected to the first DU in the TRP group according to configuration information related to the first DU in the first configuration information, and the second DU may activate the TRP connected to the second DU in the TRP group according to configuration information related to the second DU in the first configuration information; alternatively, in case the TRP group contains only TRPs connected to the second DU, the second DU may activate TRPs connected to the second DU in the TRP group according to configuration information related to the second DU in the first configuration information. After the TRP in the TRP group is activated, the virtual cell formed by the TRP group performs air interface transmission with the terminal.

In the embodiment of the application, based on the reporting information of the terminal, the TRP connected with one or more DUs in the TRP group is activated for the terminal, and a virtual cell is formed for the terminal through the TRP group after the TRP activation. Therefore, the method is suitable for the terminal requirements (especially the terminal position and the terminal service requirements), aims at dynamically organizing one or more TRPs under DUs for the terminal to form a virtual cell for air interface transmission with the terminal, and can effectively reduce cell switching of the terminal and improve the communication effect of the terminal compared with a scheme of dynamically deploying the virtual cell under one or more DUs as compared with a scheme of fixedly deploying the cell under one DU.

Based on the foregoing embodiments, it can be seen that the formation of the virtual cells may be controlled by the DUs or by the CUs. In the case where the TRP group contains TRPs connecting the TRP of the first DU and the TRP of the second DU, the control by the DU includes control by the first DU or the second DU. In the following, respective embodiments are provided for control by DU and CU, respectively.

In some embodiments, where the TRPs in the TRP group are all connected to the same DU (such as both connected to a first DU or both connected to a second DU) and the DUs control the formation of the virtual cell:

the DU may determine the TRP group and configuration information (such as the first configuration information) of the TRP group according to the reporting information of the terminal in response to the reporting information from the terminal (for example, when the DU autonomously listens or receives the reporting information from the terminal), activate the TRP in the TRP group according to the configuration information of the TRP group, and provide air interface transmission for the terminal through the activated TRP.

In some embodiments, where the TRPs in the TRP group are all connected to the same DU (such as both connected to the first DU or both connected to the second DU) and the CU controls the formation of the virtual cell:

the DU responds to the report information from the terminal and sends the report information to the CU; and/or, the DU reports the candidate TRP participating in forming the virtual cell under the DU to the CU in response to the reporting information from the terminal. The CU determines the configuration information (such as first configuration information) of the TRP group and the TRP group according to the reported information and/or the candidate TRP under the DU, and sends the configuration information to the DU; the DU activates TRP in the TRP group according to the configuration information, and provides air interface transmission for the terminal through the activated TRP.

In still other embodiments, in the case where the TRPs in the TRP group are connected to different DUs, that is, the TRP group includes the TRP connected to the first DU and the TRP connected to the second DU, the process of controlling the formation of the virtual cell by the first DU may refer to the embodiments shown in fig. 5 to 6 specifically:

fig. 5 is a second flowchart of a configuration method of a transmitting and receiving node according to an embodiment of the present application. As shown in fig. 5, the configuration method of the transmission receiving node of the present embodiment may include:

In this embodiment, the terminal may periodically send reporting information to the first DU; or, the terminal may send reporting information to the first DU when the location changes and/or the service requirement changes; alternatively, the terminal may transmit the report information to the first DU when receiving a request for the first DU to acquire the report information. The first DU may autonomously monitor or receive the report information of the terminal. Further, the MAC layer or the physical layer of the first DU may autonomously monitor or receive the report information of the terminal.

In this way, the first configuration information including these contents is transmitted to the second DU through the first DU, so that the second DU can more clearly understand the TRP of the virtual cell participating in the formation of the terminal, and can also facilitate the second DU to participate in the formation of the virtual cell more accurately.

S504, the second DU activates TRP connected with the second DU in the TRP group according to the first configuration information so as to provide air interface transmission for the terminal through the activated TRP.

S505, the first DU activates TRP connected with the first DU in the TRP group according to the first configuration information so as to provide air interface transmission for the terminal through the activated TRP.

In this embodiment, the first DU may activate the TRP connected to the first DU in the TRP group according to the configuration information related to the first DU in the first configuration information of the TRP group, so as to provide air interface transmission for the terminal through the activated TRP. Here, S504 and S505 may be executed simultaneously, or S504 may be executed first or S505 may be executed first, which is not limited herein.

In the embodiment of the application, after the first DU determines the TRP group according to the report information of the terminal, the configuration information of participating in forming the virtual cell is informed to the second DU so as to inform the second DU to participate in the deployment of the virtual cell. Therefore, the TRP under the first DU and the TRP under the second DU are flexibly deployed through the reporting information suitable for the terminal, a virtual cell is dynamically formed for the terminal, cell switching of the terminal is reduced, signal quality of the terminal is improved, and communication experience of a user is improved.

S909, the first DU activates a TRP connected with the first DU in the TRP group according to the first configuration information, so as to provide air interface transmission for the terminal through the activated TRP.

The TRP under each DU receives the uplink transmission sent by the terminal (at this time, the resource allocation under each DU is independent, and the receiving time of the TRP under each DU is also independent), and then the higher layer of the DU processes the data from the TRP.

Optionally, a plurality of DUs cooperatively process transport blocks.

In this alternative, in downlink transmission, a transmission block formed by a first DU may be sent to a second DU through an interface established between DUs, where both TRP connected by the first DU and TRP connected by the second DU may transmit the transmission block. In uplink transmission, both the first DU and the second DU may receive uplink transmission of the terminal (the resource allocation under each DU may be the same or different, and the TRP reception time under each DU may also be the same or different), and the second DU sends the received transmission data (including the parsed transmission block and/or the received original data stream) to the first DU through an inter-DU interface message.
