[0001] This invention relates to the field of communication technology, and in particular to cell parameter configuration methods, apparatus, devices, storage media, and products. Background Technology

[0002] With the development of communication technology, most base stations nowadays adopt the 5G supercell architecture, which consists of multiple transmission and reception points (TRPs) distributed in different locations. Each TRP can send a dedicated tracking reference signal (TRS). By receiving the corresponding TRS, the terminal device can achieve time and frequency tracking, thereby realizing the communication connection between the terminal device and the base station.

[0003] However, 5G supercell architectures contain a large number of TRPs, requiring maintenance personnel to configure corresponding TRS parameters for each TRP individually. This configuration process is cumbersome and prone to errors. Therefore, an automatic configuration method is urgently needed to bind TRPs and TRS resources. Summary of the Invention

[0006] According to another aspect of the present invention, a cell parameter configuration apparatus is provided, comprising: The basic configuration parameter acquisition module is used to acquire basic configuration parameters and determine the TRS transmission period corresponding to the tracking reference signal TRS based on the basic configuration parameters. The TRS parameter allocation module is used to allocate corresponding TRS parameters to each transmission and reception point (TRP) to be configured based on a preset mapping rule and with the TRS transmission period as the time domain constraint boundary.

[0010] The technical solution of this invention obtains basic configuration parameters and determines the TRS transmission period corresponding to the Tracking Reference Signal (TRS) based on the basic configuration parameters. Based on a preset mapping rule, and using the TRS transmission period as the time-domain constraint boundary, corresponding TRS parameters are allocated to each Transmission Receiving Point (TRP) to be configured.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0016] Example 1 Figure 1 This document provides a flowchart of a cell parameter configuration method according to Embodiment 1 of the present invention. This embodiment is applicable to situations involving cell parameter configuration, such as in a 5G multi-TRP collaborative scenario within a 5G supercell architecture. It describes the configuration of TRS parameters for a TRP deployed in the Frequency Range 1 (FR1) band. The configuration process conforms to the 3rd Generation Partnership Project (3GPP) standard. This method can be executed by a cell parameter configuration device, which can be implemented in hardware and / or software and can be configured within an electronic device. Figure 1 As shown, the method includes: S101. Obtain the basic configuration parameters and determine the TRS transmission period corresponding to the tracking reference signal TRS based on the basic configuration parameters.

[0017] In this embodiment, the basic configuration parameters may include TRP-related parameters and TRS-related parameters. For example, TRP-related parameters may include the total number of TRPs to be configured and the TRP index corresponding to each TRP. TRS-related parameters may include parameters used to determine the resource boundaries corresponding to the TRS parameters, such as the duplex mode corresponding to the TRP, the starting position of the resource block (RB) corresponding to the TRS resource, and the number of RBs. The duplex mode can be used to determine the time-domain boundaries corresponding to the TRS parameters, such as the TRS transmission period. The starting position and number of RBs can be used to determine the frequency-domain boundaries corresponding to the TRS parameters. The basic configuration parameters can be input by relevant maintenance personnel or a third-party system.

[0018] In this embodiment, the TRS transmission period can be understood as the time interval during which the base station periodically transmits a set of TRS signals; for example, the interval between transmitting the complete TRS signal corresponding to each TRP to be configured once. Determining the TRS transmission period corresponding to the tracking reference signal TRS based on the basic configuration parameters can specifically involve extracting the total number of TRPs to be configured and the duplex mode from the basic configuration parameters, determining the number of downlink time slot pairs required to cover the TRS resource set corresponding to each TRP based on the duplex mode, and determining the TRS transmission period based on the number of downlink time slot pairs.

[0019] S102. Based on the preset mapping rules, with the TRS transmission period as the time domain constraint boundary, assign corresponding TRS parameters to each transmission receiving point (TRP) to be configured; wherein, the preset mapping rules are constructed based on the mapping relationship between TRP and TRS resource set, the mapping relationship between TRP and downlink time slot pair, the mapping relationship between TRP and frequency domain subcarrier, and the mapping relationship between TRP and orthogonal frequency division multiplexing (OFDM) symbol pair.

[0020] In this embodiment, the TRS parameters may include a TRS resource set and various resource parameters used to carry the TRS resource set, such as downlink time slot pairs, frequency domain subcarriers, and orthogonal frequency division multiplexing (OFDM) symbol pairs; wherein, the TRS resource set may include Channel State Information Reference Signal (CSI-RS) resources.

[0021] The preset mapping rules can be pre-built based on the TRP index; specifically, the mapping relationship between TRP and TRS resource set can be determined according to the mapping rule between TRP index and TRS resource set index; the mapping relationship between TRP and downlink time slot pair can be determined according to the mapping rule between TRP index and downlink time slot pair index; the mapping relationship between TRP and frequency domain subcarrier can be determined according to the mapping rule between TRP index and frequency domain subcarrier index; and the mapping relationship between TRP and Orthogonal Frequency Division Multiplexing (OFDM) symbol pair can be determined according to the mapping rule between TRP index and OFDM symbol pair index.

[0022] For example, the corresponding TRS resource set can be determined based on the mapping rules between the TRP index and the TRS resource set index; the TRS transmission period is used to constrain the maximum number of time slot pairs that can be deployed to transmit TRS. Each TRP corresponds to a periodically transmitted TRS. The larger the TRS transmission period, the more time slot pairs can be used for orchestration. Therefore, the time domain constraint boundary can be determined based on the TRS transmission period; the downlink time slot pairs carrying the TRS resource set can be determined based on the mapping rules between the TRP index and the downlink time slot pair index; the frequency domain subcarriers carrying the TRS resource set can be determined based on the mapping rules between the TRP index and the frequency domain subcarrier index; and the OFDM symbol pairs carrying the TRS resource set can be determined based on the mapping rules between the TRP index and the OFDM symbol pair index.

[0023] This invention provides a cell parameter configuration method. The method involves obtaining basic configuration parameters and determining the TRS transmission period corresponding to the Tracking Reference Signal (TRS) based on these parameters. Based on a preset mapping rule, and using the TRS transmission period as a time-domain constraint boundary, corresponding TRS parameters are assigned to each Transmitter Receiving Point (TRP) to be configured. The preset mapping rule is constructed based on the mapping relationships between TRPs and TRS resource sets, between TRPs and downlink time slot pairs, between TRPs and frequency-domain subcarriers, and between TRPs and Orthogonal Frequency Division Multiplexing (OFDM) symbol pairs. This technical solution achieves automated binding of TRPs and TRS parameters, improving the efficiency of TRP parameter configuration. Furthermore, using the TRS transmission period as a time-domain constraint boundary constrains the distribution range of TRS parameters corresponding to each TRP, ensuring the timing consistency of the configured TRS parameters and improving the reliability of the TRP parameter configuration process.

[0024] Example 2 Figure 2 This is a flowchart of a cell parameter configuration method provided in Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. The basic configuration parameters in this embodiment include the total number of TRPs corresponding to the TRP to be configured, the number of resource blocks (RBs) corresponding to the TRS resources, and the duplex mode corresponding to the TRP; such as Figure 2 As shown, the method includes: S201. Obtain the total number of TRPs corresponding to the TRP to be configured, the number of resource blocks (RBs) corresponding to the TRS resource, and the duplex mode corresponding to the TRP.

[0025] For example, the total number of TRPs corresponding to the TRP to be configured, the number of resource blocks (RBs) corresponding to the TRS resource, and the duplex mode corresponding to the TRP can be read from the configuration file. The configuration file can be pre-entered by the operations and maintenance personnel.

[0026] The number of RBs can be understood as the number of consecutive RBs occupied by the TRS signal. In this embodiment, in order to avoid the terminal device exceeding its measurement capability when tracking and measuring the TRS signal, if the input number of RBs exceeds the preset maximum number of RBs, the number of RBs can be determined as the preset maximum number of RBs. The preset maximum number of RBs can be 52, which can be set based on the 3GPP protocol.

[0027] Duplex modes can include frequency division duplex (FDD) mode and time division duplex (TDD) mode.

[0028] S202. Based on the total number of TRPs and the maximum number of bearers, determine the minimum number of downlink time slot pairs required to send the TRS resource sets corresponding to each TRP; wherein, the maximum number of bearers is the maximum number of TRS resource sets that can be configured in a single RB of a single downlink time slot.

[0029] For example, the total number of TRPs can be divided by the maximum number of bearers, and the result can be rounded up to obtain the minimum number of downlink time slot pairs required to transmit the TRS resource set corresponding to each TRP. The maximum number of bearers can be determined by three factors: a first number of frequency domain subcarriers in a single RB (which can be 12), a second number of frequency domain subcarriers occupied by a single CSI-RS resource on a single RB (which can be 3), and a third number of OFDM symbol pairs for carrying TRS in each downlink time slot (which can be 3). For example, the first and second numbers can be divided, and the result can be multiplied by the third number to obtain the maximum number of bearers. In this embodiment, the maximum number of bearers can be 12.

[0030] S203. Based on the duplex mode, calculate the temporary minimum TRS period according to the required minimum number of downlink time slot pairs.

[0031] In this embodiment, due to the different uplink and downlink time slot distributions under different duplex modes, the calculation method for downlink time slot pairs differs. Therefore, different calculation methods are needed to determine the temporary minimum TRS period. The temporary minimum TRS period can be understood as the duration required to carry the minimum number of downlink time slot pairs. When calculating this temporary minimum TRS period, only time-domain parameters (e.g., the minimum number of downlink time slot pairs) are considered, and other parameters (e.g., the number of subsequent RBs) are not considered.

[0032] Specifically, this step may include at least one of the following A1 to A2: A1. If the duplex mode is Frequency Division Duplex (FDD) mode, then twice the number of the required minimum downlink time slot pairs shall be determined as the temporary minimum TRS period.

[0033] In FDD mode, uplink and downlink time slots are continuously distributed, and two consecutive downlink time slots constitute a downlink time slot pair. The temporary minimum TRS period can be determined by doubling the minimum number of downlink time slot pairs.

[0034] A2. If the duplex mode is Time Division Duplex (TDD), then the temporary minimum TRS period is determined based on the required minimum number of downlink time slot pairs, the total number of downlink time slot pairs corresponding to each TDD period, and the total number of time slots corresponding to each TDD period.

[0035] For example, the minimum number of downlink time slot pairs can be divided by the total number of downlink time slot pairs corresponding to each TDD cycle, the result of the division operation can be rounded up, and the rounded result can be multiplied by the total number of time slots corresponding to each TDD cycle to obtain the temporary minimum TRS cycle.

[0036] In this embodiment, under TDD mode, uplink and downlink time slots share the same spectrum, which includes uplink time slots, downlink time slots, and special time slots; the special time slots contain both uplink OFDM symbols and downlink OFDM symbols. Optionally, the total number of downlink time slot pairs corresponding to each TDD cycle can be determined by the following steps: Special time slots that can be used as downlink time slots are selected based on preset time slot selection criteria. The preset time slot selection criteria can be that the total number of downlink OFDM symbols in the special time slots is greater than a preset downlink OFDM symbol count threshold, which can be 10. The total number of downlink time slot pairs corresponding to each TDD cycle is determined based on the selected special time slots and downlink time slots.

[0037] The above steps are based on the differential calculation of the temporary minimum TRS period in duplex mode. The calculation process is adapted to the time slot distribution characteristics of FDD mode and TDD mode. In TDD mode, the total number of downlink time slot pairs and the total number of time slots corresponding to each TDD period are introduced. The distribution characteristics of mixed uplink time slots and special time slots in TDD mode are taken into account, which realizes accurate statistics of downlink time slots. This avoids the prediction deviation of the number of downlink time slot pairs caused by using the same set of calculation logic, and reduces the risk of conflict in the allocation of downlink time slot pairs.

[0038] S204. Determine the minimum TRS period based on the temporary minimum TRS period, the number of RBs, and the preset subcarrier spacing parameters.

[0039] In this embodiment, the preset subcarrier spacing parameter can be set based on the 3GPP protocol. For example, in the FR1 band, the preset subcarrier spacing parameter has a value range of [0,1].

[0040] Specifically, the minimum TRS period can be determined using different calculation methods based on the number of RBs. For example, if the number of RBs is less than or equal to the preset maximum number of RBs (e.g., 52), the minimum TRS period is determined based on the following expression: ; in, Represents the minimum TRS period; This represents the preset subcarrier spacing parameter; This represents the four numbers Xp∈{10,20,40,80} that can make the candidate periodicity... The minimum Xp, which is greater than or equal to the temporary minimum TRS period, can be determined based on the temporary minimum TRS period. For example, it can be determined using the following expression. : ; in, Represents the temporary minimum TRS period; This represents the preset subcarrier spacing parameter; One of the factors representing the calculation of the TRS period as specified in the current 3GPP standard, its value range can be... ; parameters The minimum value in the set that satisfies the above expression is taken as .

[0041] If the number of RBs is greater than the preset maximum number of RBs (e.g., 52), and the parameters are calculated through the above steps... The set satisfies the expression of If the value is 10, then the minimum TRS period can be determined using the following expression: ; in, Represents the minimum TRS period; This represents the preset subcarrier spacing parameter. The reason for using the above expression for calculation is... This is because, according to the 3GPP protocol, if the number of RBs exceeds the preset maximum number of RBs (e.g., 52), then in this case... It cannot have a value of 10, that is... The only feasible solution is from Among these values, the selection is based on the fact that... Represents the minimum TRS period, therefore, the minimum Right now Only 20 can be selected.

[0042] S205. Multiply the minimum TRS period by a preset multiple to obtain the first transmission period. Determine the smaller value between the first transmission period and the preset maximum TRS period as the TRS transmission period corresponding to the TRS.

[0043] In this embodiment, the preset maximum TRS period can be the upper limit of the TRS transmission period specified in the 3GPP protocol, for example, it can be... ;in, This represents the preset subcarrier spacing parameter. The preset multiple can be set in advance; in this embodiment, the preset multiple can be twice. In practical applications, if the preset multiple is 1, it may lead to excessive time-frequency resource overhead for the TRS, thereby affecting the transmission of higher-layer signaling during initial access and the service data throughput after access. If the preset multiple is greater than twice, it may cause wireless link failure for some terminals whose channels are changing rapidly, due to the inability to synchronize downlink with the base station in time, resulting in the terminal losing connection with the base station. Therefore, for performance considerations, the preset multiple can be set to twice.

[0044] S206. Based on the preset mapping rules, with the TRS transmission period as the time domain constraint boundary, assign corresponding TRS parameters to each transmission receiving point (TRP) to be configured; wherein, the preset mapping rules are constructed based on the mapping relationship between TRP and TRS resource set, the mapping relationship between TRP and downlink time slot pair, the mapping relationship between TRP and frequency domain subcarrier, and the mapping relationship between TRP and orthogonal frequency division multiplexing (OFDM) symbol pair.

[0045] This invention determines the minimum number of downlink time slot pairs required to transmit the TRS resource set corresponding to each TRP based on the total number of TRPs and the maximum number of bearers. The maximum number of bearers is the maximum number of TRS resource sets that can be configured in a single RB of a single downlink time slot. Based on duplex mode, a temporary minimum TRS period is calculated according to the required minimum number of downlink time slot pairs. A minimum TRS period is determined based on the temporary minimum TRS period, the number of RBs, and a preset subcarrier spacing parameter. The minimum TRS period is multiplied by a preset multiple to obtain a first transmission period. The smaller value between the first transmission period and the preset maximum TRS period is determined as the TRS transmission period corresponding to the TRS. This technical solution automates the calculation of the TRS transmission period, simplifies the tedious manual configuration steps, and improves the accuracy of the TRS transmission period calculation. Specifically, based on the duplex mode, the temporary minimum TRS period is calculated according to the required minimum number of downlink time slot pairs. This ensures that the obtained temporary minimum TRS period can fully adapt to the time slot distribution characteristics of different duplex modes. By determining the minimum TRS period based on the temporary minimum TRS period, the number of RBs, and the preset subcarrier spacing parameters, the temporary minimum TRS period can be corrected, ensuring that the obtained minimum TRS period is more reliable. This avoids the subsequent configuration of TRS resources crowding out other resources (e.g., the time-frequency resources used by the Physical Downlink Shared Channel (PDSCH), which could lead to demodulation anomalies in the terminal equipment. When the preset multiple is 2, the smaller value between twice the minimum TRS period and the preset maximum TRS period can be determined as the TRS transmission period corresponding to the TRS. This setting achieves a balance between reducing TRS resource overhead and ensuring the tracking quality of the TRS signal by the subsequent terminal equipment, ensuring that the obtained TRS transmission period is more reliable.

[0046] Example 3 Figure 3 This is a flowchart of a cell parameter configuration method provided in Embodiment 3 of the present invention. This embodiment further refines the above embodiments. In this embodiment, the basic configuration parameters include the TRP index corresponding to each TRP to be configured; the TRS parameters include the TRS resource set, downlink time slot pairs for transmitting the TRS resource set, frequency domain subcarriers, and OFDM symbol pairs. Figure 3 As shown, the method includes: S301. Obtain the basic configuration parameters and determine the TRS transmission period corresponding to the tracking reference signal TRS based on the basic configuration parameters.

[0047] In this embodiment, the basic configuration parameters may further include the TRP index corresponding to each TRP to be configured, so as to facilitate the subsequent configuration of the corresponding TRS parameters for each TRP based on the TRP index. The TRS parameters may include a TRS resource set, downlink time slot pairs for transmitting the TRS resource set, frequency domain subcarriers, and OFDM symbol pairs.

[0048] S302. For each TRP to be configured, the TRP index corresponding to the current TRP is determined as the first index value, and the TRS resource set corresponding to the first index value in the preset resource table is determined as the TRS resource set corresponding to the current TRP; wherein, the preset resource table is used to record the mapping relationship between the TRP index and the TRS resource set.

[0049] In this embodiment, each TRP can correspond to one TRS resource set. According to the 3GPP protocol, each TRS resource set can include 4 CSI-RS resources. An index can be set for each TRS resource set based on the TRP index. For example, the index of the TRS resource set can be mapped one-to-one with the TRP index. A preset resource table can be used to record the mapping relationship between the TRP index and the TRS resource set index.

[0050] Furthermore, indexes can be set for CSI-RS resources in each TRS resource set based on the TRP index. For example, the indexes for the CSI-RS resources can be set to... , , ,as well as ;in, The above steps ensure that the index of each CSI-RS resource is unique. Based on the relationship between the index of the CSI-RS resource and the TRP index, the corresponding CSI-RS resource is allocated to the TRP, which can avoid problems such as misallocation and overallocation during the allocation process.

[0051] S303. For each TRP to be configured, the result of dividing the TRP index corresponding to the current TRP by the first preset value is rounded down to obtain the second index value. The downlink time slot pair corresponding to the second index value in the time domain resource pool is determined as the downlink time slot pair of the transmission TRS resource set corresponding to the current TRP. Wherein, the first preset value is the maximum number of TRS resource sets corresponding to a single RB in a single downlink time slot pair. The time domain resource pool is constructed based on the downlink time slot pairs within the TRS transmission period.

[0052] In this embodiment, the first preset value can be set based on the 3GPP protocol. It can be the maximum number of TRS resource sets corresponding to a single RB in a single downlink time slot pair. The first preset value can be determined by multiplying the maximum number of TRS resource sets that a single RB (i.e., 12 subcarriers) can carry in the frequency domain (e.g., 12 / 3=4) with the number of OFDM symbol pairs for carrying TRS contained in a single downlink time slot (according to the 3GPP protocol, the OFDM symbol pairs for carrying TRS in a single downlink time slot can be configured as {4,8}, {5,9}, {6,10}, so the value is 3). For example, the first preset value can be 12.

[0053] The time-domain resource pool can be a set of downlink time slot pairs that can carry the transmission of TRS resource sets within the TRS transmission period, with the TRS transmission period as the time-domain boundary. Each downlink time slot pair in the time-domain resource pool carries an index value. In step S303, for each TRP to be configured, the TRP index corresponding to the current TRP is divided by a first preset value and the result is rounded down (e.g., rounded down) to obtain a second index value. The downlink time slot pair corresponding to the second index value in the time-domain resource pool is determined as the downlink time slot pair for transmitting the TRS resource set corresponding to the current TRP.

[0054] The two downlink time slots in each downlink time slot pair can also be associated with corresponding time slot offsets. This allows the time slot offsets corresponding to the two downlink time slots in the pair to be obtained after determining the downlink time slot pair using the second index value. This setting can further improve the binding efficiency of TRP and TRS parameters, enabling the corresponding time slot offsets to be determined without any further operations after determining the downlink time slot pair.

[0055] S304. For each TRP to be configured, take the remainder of the TRP index corresponding to the current TRP with respect to the second preset value to obtain the third index value, and determine the frequency domain subcarrier corresponding to the third index value as the frequency domain subcarrier corresponding to the current TRP; wherein, the second preset value is the number of TRS resource sets corresponding to a single RB.

[0056] In this embodiment, the second preset value can be set based on the 3GPP protocol. It can be the number of TRS resource sets that a single RB can carry in the frequency domain. According to the 3GPP protocol, for the FR1 band, the same TRS resource set includes four co-frequency CSI-RS resources with a frequency domain density of three subcarriers (that is, four different CSI-RS resources included in one TRS resource set, whose frequency domain positions are exactly the same, only their time domain positions are different). Therefore, four different positions in the frequency domain correspond to four TRS resource sets (that is, different TRS resource sets have different positions in the frequency domain. Within one RB (i.e., 12 subcarriers), there can be a maximum of four different frequency domain positions, so from the perspective of the frequency domain, a maximum of four different TRS resource sets can be deployed). Therefore, the second preset value can be 4.

[0057] For each TRP to be configured, after determining its corresponding downlink time slot pair, the third index value can be obtained by taking the remainder of the second preset value based on the TRP index corresponding to the current TRP through S304, and the frequency domain subcarrier corresponding to the third index value is determined as the frequency domain subcarrier corresponding to the current TRP.

[0058] S305. For each TRP to be configured, the result of dividing the TRP index corresponding to the current TRP by the second preset value is rounded down to obtain a first result. Then, the first result is used to take the remainder of the third preset value to obtain a fourth index value. The OFDM symbol pair corresponding to the fourth index value in the downlink time slot pair corresponding to the current TRP is determined as the OFDM symbol pair corresponding to the current TRP. Wherein, the third preset value is the number of OFDM symbol pairs used to carry the TRS resource set in a single downlink time slot.

[0059] In this embodiment, the third preset value can be set based on the 3GPP protocol. It can be the number of OFDM symbol pairs included in a single downlink time slot for carrying TRS resource sets. For example, according to the 3GPP protocol, the OFDM symbol pairs that can be configured in a single downlink time slot are {4,8}, {5,9}, and {6,10}. Therefore, the third preset value can be 3.

[0060] For each TRP to be configured, after determining its corresponding downlink time slot pair, the result of dividing the TRP index corresponding to the current TRP by the second preset value can be rounded down (e.g., rounded down) to obtain the first result. Then, the first result is used to take the remainder of the third preset value to obtain the fourth index value. The OFDM symbol pair corresponding to the fourth index value in the downlink time slot pair corresponding to the current TRP is determined as the OFDM symbol pair corresponding to the current TRP.

[0061] This invention transforms the complex correspondence between TRP and TRS parameters into an index-based mapping relationship, enabling the allocation of TRS parameters by performing integer division and modulo operations on the TRP index. This simplifies the TRS parameter allocation process and improves the efficiency of parameter configuration.

[0062] In some embodiments, after binding TRPs with TRS parameters, based on the signal quality between the terminal device and the TRPs, and according to the capabilities of the terminal device, several TRPs for which the terminal device needs downlink synchronization can be determined. Then, for the terminal device, the CSI-RS resources in the TRS resource sets corresponding to these TRPs can be configured, thereby improving the time-frequency synchronization accuracy of the terminal device. Specifically, in this embodiment, the TRS parameters corresponding to the TRPs include a TRS resource set; the TRS resource set includes Channel State Information Reference Signal (CSI-RS) resources. After allocating corresponding TRS parameters to each Transmission Receiving Point (TRP) to be configured, the method further includes: sorting each TRP according to the signal quality between the TRP and the target terminal device; filtering a preset number of TRPs from the sorting results; determining a target TRP set based on the filtered TRPs; configuring the CSI-RS resources in the TRS resource set corresponding to each TRP in the target TRP set as non-zero power (NZP) CSI-RS resources for the target terminal device; and configuring the CSI-RS resources in the TRS resource set corresponding to each TRP not selected from the target TRP set as zero-power (ZP) CSI-RS resources for the target terminal device to perform rate matching of the Physical Downlink Shared Channel (PDSCH).

[0063] In this embodiment, the target terminal device refers to the terminal device that needs to perform TRP screening and specifically configure NZP CSI-RS and ZP CSI-RS resources. Signal quality can be determined based on the Reference Signal Received Power (RSRP) or Signal to Interference plus Noise Ratio (SINR) of a preset signal; wherein, the preset signal can be a Sounding Reference Signal (SRS) sent by the target terminal device or a Preamble signal sent by the target terminal device. The preset number can be determined based on the number of TRS resource sets supported by the target terminal device; for example, the smaller value between the number of TRS resource sets configured in the base station's TRP and the number of TRS resource sets supported by the target terminal device can be determined as the preset number. The target TRP set is the selected set of TRPs for the target terminal device.

[0064] For example, based on the RSRPs received by the TRP from the preset signals sent by the target terminal device, the TRPs can be sorted in descending order. A preset number of TRPs at the top of the sorting results are then selected to form a target TRP set for the target terminal device. Subsequently, the CSI-RS resources in the TRS resource sets corresponding to each TRP in the target TRP set are configured as NZP CSI-RS resources, and the Transmission Configuration Indicator State (TCI-state) corresponding to each TRP in the target TRP set is added to the TCI state lists of the Physical Downlink Control Channel (PDCCH) and PDSCH of the target terminal device. The CSI-RS resources in the TRS resource sets corresponding to each TRP not selected for the target TRP set are configured as ZP CSI-RS resources.

[0065] In some embodiments, if the signal quality between the target terminal device and the TRP changes, the TRPs are reordered according to the signal quality between the TRP and the target terminal device, a preset number of TRPs are selected from the sorting results, and a candidate TRP set is determined based on the selected TRPs. TRPs that exist in the target TRP set but not in the candidate TRP set are identified as target TRPs to be removed, and the CSI-RS resources corresponding to the target TRPs are changed from NZP CSI-RS resources to ZP CSI-RS resources. TRPs that do not exist in the target TRP set but exist in the candidate TRP set are identified as target TRPs to be selected, and the CSI-RS resources corresponding to the target TRPs are changed from ZP CSI-RS resources to NZP CSI-RS resources. The advantage of this setting is that if the signal quality between the terminal device and the TRP changes during the movement of the terminal device, the TRP can be reselected and the corresponding TRS resource set configuration can be switched. This allows the TRS resource set corresponding to the terminal device to be updated adaptively according to the signal quality during the movement, thereby improving the reliability of data transmission and reception between the terminal device and the TRP.

[0066] For example, a TRP can receive a preset signal (e.g., SRS or Preamble signal) sent by a target terminal device in real time and determine whether the RSRP variation range of the preset signal exceeds the corresponding threshold. If it does, it indicates that the signal quality has changed. In this case, the TRPs can be reordered in descending order based on the signal quality (e.g., the RSRP of the preset signal). A preset number of TRPs with the highest ranking can be selected from the sorting results, and these TRPs can be combined into a candidate TRP set. TRPs that exist in the target TRP set but not in the candidate TRP set are identified as target TRPs to be removed. The CSI-RS resource corresponding to the target TRP is changed from NZP CSI-RS resource to ZP CSI-RS resource, and the TCI-state corresponding to the target TRP is removed from the TCI state list of the configured PDCCH and PDSCH. In addition, TRPs that do not exist in the target TRP set but exist in the candidate TRP set are identified as target selected TRPs, and the CSI-RS resources corresponding to the target selected TRPs are changed from ZP CSI-RS resources to NZP CSI-RS resources. The TCI-state corresponding to the target selected TRPs is added to the TCI state list of the configured PDCCH and PDSCH.

[0067] For example, as the terminal device moves within the entire signal coverage area of ​​the 5G supercell, the received signal strength of each TRP to the terminal device will also change dynamically, thus changing the order of each TRP. Therefore, the configuration parameters of some TRPs that were not selected and some TRPs that were selected need to be swapped. Specifically, the base station needs to change the four CSI-RS resources in the TRS resource set corresponding to each TRP that will change from "selected" to "not selected" from NZP CSI-RS resources to ZP CSI-RS resources, and also needs to remove the TCI-state corresponding to the TRS resource set of this part of the TRP from the configured TCI state list (e.g., the TCI state list of PDCCH and PDSCH); while for the four CSI-RS resources in the TRS resource set corresponding to each TRP that will change from "not selected" to "selected", they need to change the four CSI-RS resources in the TRS resource set corresponding to each TRP from ZP CSI-RS resources to NZPCSI-RS resources, and also need to add the TCI-state corresponding to the TRS resource set of this part of the TRP to the TCI state list (e.g., the TCI state list of PDCCH and PDSCH).

[0068] The specific reconfiguration method is as follows: Based on the latest measurement results of the received signal strength of each TRP to the terminal device, the top S TRPs are re-ranked and formed into TRP set A (i.e., the "to be selected" TRP set). Set A is compared with the original TRP set B (i.e., the "selected" TRP set) composed of the original S TRPs with configured NZP CSI-RS resources. If A != B, then the configuration is performed in the reconfiguration message corresponding to Radio Resource Control (RRC) according to the following steps B1-B6: B1. Add the four CSI-RS resources in the TRS resource set corresponding to each TRP that does not belong to set A but belongs to set B to the "Pending Release" NZP CSI-RS resource list; configure the four CSI-RS resources in the TRS resource set corresponding to each TRP that belongs to set A but does not belong to set B as NZP CSI-RS and add them to the "Pending Addition" NZP CSI-RS resource list.

[0069] B2. Release the configured periodic ZP CSI-RS resource set, and add the 4 CSI-RS resources in the TRS resource set corresponding to each TRP that does not belong to set A' (representing the complement of A) but belongs to set B' (representing the complement of B) to the list of ZP CSI-RS resources to be released; configure the 4 CSI-RS resources in the TRS resource set corresponding to each TRP that belongs to set A' but not to set B' as ZP CSI-RS resources, and add them to the list of ZP CSI-RS resources to be added.

[0070] B3. Re-establish the periodic ZP CSI-RS resource set, and add the 4 CSI-RS resources in the TRS resource set corresponding to each TRP in set A' to the ZP CSI-RS resource master table.

[0071] B4. Configure the quasi-co-location reference of the TCI status of the four CSI-RS resources in the TRS resource set corresponding to each newly selected TRP as a preset TCI status identifier; the preset TCI status identifier represents that these CSI-RS resources have a quasi-co-location relationship with the Synchronization Signal Block (SSB) indexed by the 5G supercell with Quasi-Co-Located Type C (QCL Type C).

[0072] B5. Add the TCI-states corresponding to TRPs that do not belong to set A but belong to set B to the list of TCI states to be released (e.g., the TCI state lists of PDCCH and PDSCH); add the TCI-states corresponding to TRPs that belong to set A but not to set B to the list of TCI states to be added, wherein each TCI-state has a quasi-co-located relationship of Quasi-Co-LocatedType A (QCL Type A) with the first CSI-RS resource in the TRS resource set corresponding to each of these newly selected TRPs.

[0073] B6. Form a TRS resource set by combining the four CSI-RS resources in the TRS resource set corresponding to each newly selected TRP, set the resource set ID to the index of the newly selected TRP, and set the TRS signal identifier parameter "trs-Info" to the enabled state, for example, set it to "true"; put these reconfigured CSI-RS resources into the CSI resource configuration table to be added; put the CSI-RS resources corresponding to the TRS resource sets of TRPs that do not belong to set A but belong to set B into the CSI resource configuration table to be released.

The TRS parameter allocation module is used to allocate corresponding TRS parameters to each transmission and reception point (TRP) to be configured based on a preset mapping rule and with the TRS transmission period as the time domain constraint boundary. The preset mapping rule is constructed based on the mapping relationship between TRP and TRS resource set, the mapping relationship between TRP and downlink time slot pair, the mapping relationship between TRP and frequency domain subcarrier, and the mapping relationship between TRP and orthogonal frequency division multiplexing (OFDM) symbol pair.

[0076] This invention provides a cell parameter configuration device that acquires basic configuration parameters and determines the TRS transmission period corresponding to the Tracking Reference Signal (TRS) based on the basic configuration parameters.

The OFDM symbol pair corresponding to the fourth index value in the downlink slot pair corresponding to the current TRP is determined as the OFDM symbol pair corresponding to the current TRP; wherein, the third preset value is the number of OFDM symbol pairs used to carry the TRS resource set in a single downlink slot.
