For the cooperative perception mode, the uplink channel configuration of a receiving node has an impact on the downlink channel configuration of a sending node. The receiving node receives not only the signals sent by the uplink communication user, but also the perception signals of the adjacent node, which causes mutual interference between the communication function and the perception function, leading to a conflict between the perception resource and the communication resource, and further affecting the performance of perception and communication.

[0030] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0031] Please refer to FIG. 1, which is a flow schematic diagram of a downlink channel configuration method provided by the present disclosure. The downlink channel configuration method comprises steps S1 and S2.

[0032] S1, when a first network device and a second network device are in a cooperative sensing mode, obtaining uplink communication resource configuration information of the second network device;

[0033] S2, configuring downlink sensing resources of the first network device according to the uplink communication resource configuration information.

[0034] It should be noted that the communication and sensing integrated system includes two working modes: independent sensing and cooperative sensing. Please refer to FIG. 2 and FIG. 3, FIG. 2 is a schematic diagram of an independent sensing mode in a downlink channel configuration method provided by the present disclosure, and FIG. 3 is a schematic diagram of a cooperative sensing mode in a downlink channel configuration method provided by the present disclosure. Independent sensing is similar to a radar system. A sensing node first transmits a sensing signal to a non-network / in-network target, then receives a corresponding echo signal of the sensing signal by using a sensing receiver, and realizes sensing functions such as target detection, positioning, imaging, identification, and tracking through extraction and processing of the echo information. Relying on the large-scale deployment of mobile communication networks, a cooperative sensing network is constructed, which has advantages such as cooperative reception and fusion processing gain, no need for self-interference deletion, no need for hardware modification, low-cost and rapid technology landing, etc.

[0035] However, in actual networking, the cooperative sensing mode of A-to-B reception needs to change the uplink and downlink configuration of the transmitting and receiving nodes, breaking the traditional uplink and downlink configuration mode. For cooperative sensing, node B receives the uplink communication signals sent by the user while also receiving the sensing signals of the adjacent nodes. For example, refer to FIG. 4, which is a schematic diagram of network cooperative sensing in a downlink channel configuration method provided by the present disclosure. In the coverage area of node B, node B receives the uplink communication signals sent by communication users 1 to 3 and the sensing signals sent by node A and reflected by target 1. At this time, communication users 1 to 3 send uplink communication signals, and the sensing signals sent by node A include PDCCH / PDSCH transmission resources, causing mutual interference between the communication function and the sensing function. Therefore, the downlink channel of node A needs to be configured to avoid interference of the sensing signals with the uplink user communication signals of node B.

[0036] Specifically, the embodiment of the present disclosure provides a downlink channel configuration method. When a first network device and a second network device are in a cooperative sensing mode, the uplink communication resource configuration information of the second network device is obtained. The first network device serves as a transmitting node (i.e., node A), the second network device serves as a receiving node (i.e., node B), and the first network device and the second network device form a cooperative node cluster. After obtaining the uplink communication resource configuration information of the second network device, the downlink sensing resource of the first network device is configured according to the uplink communication resource configuration information of the second network device. In this way, the present disclosure avoids interference of the sensing signals with the user communication signals by constructing a unified uplink and downlink channel throughout the network, thereby ensuring normal communication of the communication users and effective detection of the sensing signals.

[0037] It should be noted that the form of communication between the first network device and the second network device in the embodiment of the present disclosure includes but is not limited to transmission forms such as XN interface and air interface.

[0038] In another embodiment, the uplink communication resource configuration information is communication user resource information pre-configured by a higher layer according to different granularities, and the uplink communication resource configuration information includes first communication resource configuration information and second communication resource configuration information.

[0039] Specifically, in the embodiment of the present disclosure, the uplink communication resource configuration information is communication user resource information pre-configured by a higher layer according to different granularities, and the uplink communication resource configuration information includes first communication resource configuration information and second communication resource configuration information. The granularity refers to the smallest unit or precision of the resources allocated to the user. These resources can be frequency, time, space, etc. The size of the granularity determines the flexibility and precision of the resource allocation that the system can provide to the user.

[0040] In yet another embodiment, the first communication resource configuration information is bandwidth segment information, the bandwidth segment information including semi-static segments; and the second communication resource configuration information is configuration mode indication information, the configuration mode indication information including semi-static or dynamic configuration mode sets.

[0041] In yet another embodiment, the configuration mode set includes at least one configuration mode; each configuration mode includes at least one resource block; and the second network device configures each communication user with any configuration mode in the configuration mode set through RRC semi-static configuration or RRC dynamic configuration; the semi-static configuration mode is fixedly effective according to a preset time slot and resource location, and the dynamic configuration mode is effective according to an activation instruction to select a corresponding configuration mode.

[0042] Specifically, the first communication resource configuration information is active BWP segment information, which indicates the resource block configured by the node B for communication, and can be expressed by locationAndBandwidth to indicate the frequency domain location and bandwidth of the active BWP, by subcarrierSpacing to indicate the subcarrier spacing, and by cyclicPrefix to indicate whether to use an extended cyclic prefix for the bandwidth part. For example, the active BWP segment information configured by the node B for communication is as follows: BWP::=SEQUENCE{ locationAndBandwidth INTEGER(0..37949), subcarrierSpacing SubcarrierSpacing, cyclicPrefix ENUMERATED{extended}OPTIONAL--Need R}

[0043] The second communication resource configuration information is configuration mode indication information, and the configuration mode indication information includes a semi-static or dynamic configuration mode set. The configuration mode set includes at least one Pattern configuration mode, and each configuration mode includes at least one resource block. Pattern information represents specific time-frequency resources configured for a communication user, and the information of the time-frequency resources includes but is not limited to a starting frame number, a time slot offset, a time slot number, a starting symbol number, a symbol number, a frequency domain starting PRB, and a PRB number. For example: PatternResource::=SEQUENCE{ Pattern-ResourceId Pattern-ResourceId, resourceMapping Pattern-ResourceMapping, periodicityAndOffset ResourcePeriodicityAndOffset OPTIONAL,} Pattern-ResourceId::=INTEGER(0..N-1) Pattern-ResourceMapping::=SEQUENCE{ startingPRB 2 nrofPRBs 8 startingSymbol 2 nrofSymbols 8} ResourcePeriodicityAndOffset::=CHOICE{ slots8 6,}

[0044] The second network device configures any configuration mode (i.e., a Pattern pattern) in the Pattern configuration mode set for each communication user through RRC semi-static configuration or RRC dynamic configuration. It should be noted that the time-frequency resource position indicated by the uplink DCI when scheduling the uplink PUSCH transmission needs to be limited within the configured Pattern resource range, and the position of the corresponding PUCCH resource configured for the UE for UCI reporting also needs to be limited within the Pattern resource range. The RRC can configure a periodic (semi-static) or aperiodic (dynamic) Pattern. If the Pattern is configured to be periodic, it is fixedly effective according to the configured time slot and resource position. If the Pattern is configured to be aperiodic, it is configured as a group of patterns, for example, four patterns. When the dynamic PUSCH or PUCCH transmission is performed, one of the four patterns is activated in the DCI to be effective.

[0045] For example, referring to FIG. 5, which is a schematic diagram of a reserved user frequency band of a node B in a downlink channel configuration method provided by the present disclosure. For two nodes, the uplink channel resource configured for the node B user can be an active BWP frequency band, as shown in FIG. 5. Referring to FIG. 6, which is a schematic diagram of a communication resource configuration mode set in a downlink channel configuration method provided by the present disclosure. For two nodes, the uplink channel resource configured for the node B user can be N Pattern sets, as shown in FIG. 6. The Pattern configuration mode indication information indicates the Pattern indication of the node B communication resource configuration, which can be represented by a variable CommunicationPattern, and is used to indicate the Pattern pattern configured by the node B for multiple communication users. For example, the Pattern indication is {1, 3} (indicating that the node B configures the communication resource as {Pattern 1, Pattern 3}).

[0046] In yet another embodiment, the configuring the downlink sensing resource of the first network device according to the uplink communication resource configuration information comprises: when the uplink communication resource configuration information is the first communication resource configuration information, removing the frequency band corresponding to the first communication resource configuration information from the resource block to obtain a first candidate resource block; and configuring the downlink sensing resource of the first network device according to the first candidate resource block.

[0047] Specifically, for the node A that transmits the sensing information, a high layer pre-configures a PDSCH / PDCCH resource set for sensing, i.e., the sensing signal PDSCH / PDCCH resource should avoid the time-frequency resource used by the uplink communication user of the node B, and the node A selects a sensing resource configuration scheme according to the different communication resource configurations of the node B. When the uplink communication resource configuration information of the node B is the first communication resource configuration information, the frequency band corresponding to the first communication resource configuration information is removed from the resource block to obtain a first candidate resource block, and then the downlink sensing resource of the first network device is configured according to the first candidate resource block. Since the node B configures the determined frequency domain resource block for the communication user, the node A can perform sensing resource configuration in the resource block for sensing, thereby avoiding the frequency domain resource of the uplink communication user of the node B.

[0048] In yet another embodiment, the configuring the downlink sensing resource of the first network device according to the uplink communication resource configuration information comprises: when the uplink communication resource configuration information is the second communication resource configuration information, removing the configuration mode set indicated by the second communication resource configuration information from the resource block to obtain a second candidate resource block; and configuring the downlink sensing resource of the first network device according to the second candidate resource block.

[0049] Specifically, when the uplink communication resource configuration information of the node B is the second communication resource configuration information, the set of configuration modes indicated by the second communication resource configuration information is removed from the resource blocks to obtain second candidate resource blocks, and then the downlink sensing resources of the first network device are configured according to the second candidate resource blocks. For example, the node B configures the communication user resource Pattern as Pattern 1, Pattern 2, …, Pattern N in FIG. 6, and when the high layer configures the set of PDSCH / PDCCH resources, the Pattern 1, Pattern 2, …, Pattern N corresponding to the communication user resource of the node B will not be configured to the sensing resources of the node A, that is, the sensing resources configured after the node A avoids the conflict resources, as shown in FIG. 7. FIG. 7 is a schematic diagram of the sensing resources configured after the conflict avoidance in the downlink channel configuration method provided by the present disclosure.

[0050] In some embodiments, the method further comprises: when the first network device and the second network device are in the non-cooperative sensing mode, restoring the initial downlink sensing resource configuration mode.

[0051] It should be noted that when the first network device and the second network device are in the non-cooperative sensing mode, the above downlink channel resource configuration constraint is invalid, and is restored to the initial downlink sensing resource configuration mode.

[0052] The downlink channel configuration method provided by the present disclosure is further described below in combination with FIG. 8 and FIG. 9. FIG. 8 is another schematic diagram of the set of communication resource configuration modes in the downlink channel configuration method provided by the present disclosure, and FIG. 9 is another schematic diagram of the sensing resources configured after the conflict avoidance in the downlink channel configuration method provided by the present disclosure.

[0053] The node B high layer pre-configures the communication user resource. For the two nodes, the resource configured to the communication user of the node B is the set of Pattern as shown in FIG. 8.

[0054] The node A obtains the uplink communication resource configuration information of the node B, that is, the node B sends the first parameter information to the node A. At this time, the first parameter information is the Pattern indication information, which is indicated as {1}, indicating that the Pattern pattern configured to the communication user of the node B is Pattern 1.

[0055] For the node A transmitting the sensing information, a high layer pre-configures a PDSCH / PDCCH resource set for sensing, and the sensing signal PDSCH / PDCCH resource should avoid the time-frequency resource used by the uplink communication user of the node B. The node A obtains the communication user resource Pattern configured by the node B, as shown in Pattern 1 in FIG. 8. Therefore, in the high layer pre-configured PDSCH / PDCCH resource set, the Pattern configured by the node B for the communication user is not configured for the node A sensing resource. That is, the node A configures the sensing resource after avoiding the conflict resource, as shown in FIG. 9.

[0056] Correspondingly, the disclosure also provides a downlink channel configuration device capable of implementing all processes of the downlink channel configuration method in the above embodiments.
