[0150] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0151] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit (Control Unit). The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0152] In some embodiments, the core network device may be a single device, or may be multiple devices or a group of devices. The core network may include at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0153] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0154] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are examples. The communication system may include all or part of the entities shown in FIG1A , or may include other entities outside of FIG1A . The number and form of the entities are arbitrary. The entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected. The connection may be in any manner, whether direct or indirect, and may be wired or wireless.

[0155] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0156] In some embodiments of the present disclosure, the antenna size can be expanded to 4 times the original size. For example, the number of antenna ports can be 64 or 128.

[0157] In some embodiments, when the number of antenna ports is 64 or 128, 64 or 128 CSI-RS ports are required to implement channel measurement for the antenna ports.

[0158] In some embodiments, when the number of antenna ports is greater than 1, CSI-RS resources may be obtained by aggregating multiple Code Domain Multiplex (CDM) groups.

[0159] In some embodiments, FIG1B is a schematic diagram of a CDM group according to an embodiment of the present disclosure. As shown in FIG1B , the CDM group may include CDM-2 (FD2), CDM-4 (FD2, TD2), and CDM-8 (FD2, TD4).

[0160] In some embodiments, the number of CSI-RS ports may include 1, 2, 4, 8, 12, 16, 24, and 32. When the number of antenna ports increases, the CSI-RS or CSI reporting needs to be expanded or enhanced to support larger antenna scale deployment.

[0161] In some embodiments, 64 or 128 CSI-RS ports can be redesigned, but this will significantly increase the workload.

[0162] Because CSI-RS resources are designed to include a variety of port counts, they can be expanded to accommodate channel measurements for more antenna ports. Therefore, how to expand CSI-RS resources to ensure higher channel measurement accuracy while supporting channel measurements for more antenna ports deployed on the network side has become a pressing issue.

[0163] FIG2A is an interactive schematic diagram of a resource configuration method according to an embodiment of the present disclosure. The method can be executed by the above-mentioned communication system. As shown in FIG2A , the method may include:

[0164] Step S2101: The network device sends first information to the terminal device.

[0165] In some embodiments, the terminal device may receive the first information. For example, the terminal device may receive the first information sent by a network device. For another example, the terminal device may also receive the first information sent by another entity.

[0166] In some embodiments, the first information may include first indication information, which is used to indicate the location of a first signal resource, where the first signal resource is at least one signal resource among multiple signal resources, and different signal resources are used to measure channels corresponding to different antenna ports.

[0167] In some embodiments, the multiple signal resources may belong to the same resource set or different resource sets.

[0168] In some embodiments, multiple signal resources belong to at least one resource set, and the resource information of different resource sets is different. The resource information includes at least one of the following: the number of ports, density, the starting position of the resource block, the number of resource blocks, and the CDM group type, wherein the same port index in different resource information has the same subcarrier position or orthogonal frequency division multiplexing (OFDM) symbol position.

[0169] For example, if multiple signal resources belong to the same resource set, the multiple signal resources may have the same number of ports, density, starting position of resource blocks, number of resource blocks or CDM group type; if multiple signal resources belong to different resource sets, the multiple signal resources may have different number of ports, density, starting position of resource blocks, number of resource blocks or CDM group types.

[0170] In some embodiments, the signal resource may be a CSI-RS resource.

[0171] In some embodiments, the name of the first indication information is not limited, and may be, for example, "location indication information", "signal resource location indication information", "reference signal resource location indication information", etc.

[0172] In some embodiments, the first signal resource may be any signal resource among a plurality of signal resources.

[0173] In some embodiments, the first signal resource may be any number of signal resources among the plurality of signal resources, and the number of signal resources included in the first signal resource is less than the total number of the plurality of signal resources. For example, if the plurality of signal resources includes six signal resources, the first signal resource may include any two of the six signal resources.

[0174] In some embodiments, the first signal resource may be within one or more adjacent time slots, or within one or more adjacent physical resource blocks (PRBs).

[0175] For example, if the first signal resource can be within one or more adjacent time slots, then other signal resources among the multiple signal resources can be adjacent to the first signal resource in the time domain; if the first signal resource can be within one or more adjacent PRBs, then other signal resources among the multiple signal resources can be adjacent to the first signal resource in the frequency domain.

[0176] In some embodiments, the signal resources other than the first signal resource among the plurality of signal resources are second signal resources.

[0177] In some embodiments, the second signal resource may include multiple CDM groups, and the first information may also include second indication information, which can be used to indicate the position of the first CDM group. The first CDM group is a CDM group among the multiple CDM groups except the second CDM group, and the second CDM group is any CDM group among the multiple CDM groups of the second signal resource.

[0178] In some embodiments, the second indication information may also include the time domain position and frequency domain position of the first CDM group.

[0179] In some embodiments, the second indication information may include the positional relationship between multiple CDM groups of the first signal resource.

[0180] In some embodiments, the name of the second indication information is not limited, for example, it can be "position indication information", "CDM group position indication information", "information indicating the position of the CDM group", etc.

[0181] In some embodiments, the position may include a time domain position and a frequency domain position.

[0182] In some embodiments, the position may be a starting position, for example, the position may include a time domain starting position and a frequency domain starting position.

[0183] In some embodiments, the position may also be an end position. For example, the position may include a time domain end position and a frequency domain end position.

[0184] It should be noted that the location may also be other predefined information that can represent the location, and the embodiments of the present disclosure are not limited to this.

[0185] Step S2102: The terminal device determines a first position and a second position of a second signal resource based on the position of the first signal resource and the adjacent relationship between multiple signal resources.

[0186] In some embodiments, the first position may be a time domain position or a frequency domain position, and the second position may be a position different from the first position in the time domain position or the frequency domain position.

[0187] For example, if the first position is a time domain position, the second position is a frequency domain position; if the first position is a frequency domain position, the second position is a time domain position.

[0188] In some embodiments, the neighbor relationship between the plurality of signal resources may include a neighbor relationship between a first signal resource and a second signal resource, and a neighbor relationship between the second signal resources.

[0189] For example, if the network device configures three signal resources for the terminal device, the signal resources are identified as 0, 1, and 2 respectively, signal resource 0 is the first signal resource, signal resource 1 and signal resource 2 are the second signal resources, then the adjacent relationship between the three signal resources can be that signal resource 1 is adjacent to signal resource 0, and signal resource 2 is adjacent to signal resource 1.

[0190] In some embodiments, the neighbor relationship between the plurality of signal resources may be predefined.

[0191] In one implementation, the adjacent relationship between multiple signal resources may be predefined according to the identifiers of the signal resources, for example, signal resource 0 is adjacent to signal resource 1, and signal resource 2 is adjacent to signal resource 1.

[0192] In some embodiments, the neighbor relationship between the plurality of signal resources may be indicated by a network device.

[0193] In one implementation, the first information may include third indication information, and the third indication information may be used to indicate a neighbor relationship between multiple signal resources.

[0194] In some embodiments, the second signal resource may include a CDM group, and the terminal device may use the first position of the first signal resource as the first position of the second signal resource; determine the adjacent position of the second position of the first signal resource; and determine the second position of the second signal resource based on the adjacent relationship between the adjacent position and multiple signal resources.

[0195] For example, if the first position is a time domain position, the time domain position of the first signal resource can be used as the time domain position of the second signal resource; if the first position is a frequency domain position, the frequency domain position of the first signal resource can be used as the frequency domain position of the second signal resource.

[0196] For another example, if the first position is the time domain starting position, the time domain starting position of the first signal resource can be used as the time domain starting position of the second signal resource; if the first position is the frequency domain starting position, the frequency domain starting position of the first signal resource can be used as the frequency domain starting position of the second signal resource.

[0197] In some embodiments, the adjacent positions may include adjacent time domain positions or adjacent frequency domain positions.

[0198] For example, if the second position is a time domain position, the adjacent position can be the adjacent time domain position of the time domain position of the first signal resource; if the second position is a frequency domain position, the adjacent position can be the adjacent frequency domain position of the frequency domain position of the first signal resource.

[0199] Figure 2B is a schematic diagram of a first signal resource according to an embodiment of the present disclosure. As shown in Figure 2B, if the second position is a time domain position, the adjacent time domain position can be located to the left of the second position or to the right of the second position; if the second position is a frequency domain position, the adjacent frequency domain position can be located above the second position.

[0200] It should be noted that the position of the first signal resource shown in FIG2B is for exemplary purposes only and is not limited in this disclosure.

[0201] In some embodiments, after the terminal device determines the adjacent position of the second position of the first signal resource, it can determine the second position of each second signal resource separately according to the adjacent relationship between the adjacent position and multiple signal resources.

[0202] For example, if the network device configures two signal resources for the terminal device, the signal resource identifiers are 0 and 1 respectively, signal resource 0 is the first signal resource, signal resource 1 is the second signal resource, and the first position is the time domain position, then the time domain position of signal resource 0 can be used as the time domain position of signal resource 1, and the adjacent position of the frequency domain position of signal resource 0 can be used as the frequency domain position of signal resource 1.

[0203] Figure 2C is a schematic diagram of a signal resource position according to an embodiment of the present disclosure. As shown in Figure 2C, the time domain position of signal resource 1 is the same as the time domain position of signal resource 0, that is, the OFDM symbol position of signal resource 1 is the same as the OFDM symbol position of signal resource 0, and the frequency domain position of signal resource 1 is adjacent to the frequency domain position of signal resource 0.

[0204] For another example, if the network device configures three signal resources for the terminal device, the signal resources are identified as 0, 1, and 2 respectively, signal resource 0 is the first signal resource, signal resource 1 and signal resource 2 are the second signal resources, and the first position is the time domain position, then the time domain position of signal resource 0 can be used as the time domain position of signal resource 1 and signal resource 2, and the adjacent position of the frequency domain position of signal resource 0 can be used as the frequency domain position of signal resource 1 and signal resource 2.

[0205] Figure 2D is a schematic diagram of a signal resource position according to an embodiment of the present disclosure. As shown in Figure 2D, the time domain position of signal resource 1 and signal resource 2 is the same as the time domain position of signal resource 0, that is, the OFDM symbol position of signal resource 1 and signal resource 2 is the same as the OFDM symbol position of signal resource 0, and the frequency domain position of signal resource 1 and signal resource 2 is adjacent to the frequency domain position of signal resource 0.

[0206] In some embodiments, Figure 2D can also be interpreted as taking the time domain starting position of signal resource 0 as the time domain starting position of signal resource 1, taking the adjacent position of the frequency domain ending position of signal resource 0 as the frequency domain starting position of signal resource 1, taking the time domain ending position of signal resource 1 as the time domain starting position of signal resource 2, and taking the frequency domain position of signal resource 1 as the frequency domain position of signal resource 2.

[0207] For another example, if the network device configures two signal resources for the terminal device, the signal resource identifiers are 0 and 1 respectively, signal resource 0 is the first signal resource, signal resource 1 is the second signal resource, and the first position is the frequency domain position, then the frequency domain position of signal resource 0 can be used as the frequency domain position of signal resource 1, and the adjacent position of the time domain position of signal resource 0 can be used as the time domain position of signal resource 1.

[0208] Figure 2E is a schematic diagram of a signal resource position according to an embodiment of the present disclosure. As shown in Figure 2E, the frequency domain position of signal resource 1 is the same as the frequency domain position of signal resource 0, and the time domain position of signal resource 1 is adjacent to the time domain position of signal resource 0.

[0209] For another example, if the network device configures three signal resources for the terminal device, the signal resources are identified as 0, 1, and 2 respectively, signal resource 0 is the first signal resource, signal resource 1 and signal resource 2 are the second signal resources, and the first position is the frequency domain position, then the frequency domain position of signal resource 0 can be used as the frequency domain position of signal resource 1 and signal resource 2, and the adjacent position of the time domain position of signal resource 0 can be used as the time domain position of signal resource 1 and signal resource 2.

[0210] Figure 2F is a schematic diagram of a signal resource position according to an embodiment of the present disclosure. As shown in Figure 2F, the frequency domain position of signal resource 1 and signal resource 2 is the same as the frequency domain position of signal resource 0, that is, the subcarrier position of signal resource 1 and signal resource 2 is the same as the subcarrier position of signal resource 0, and the time domain position of signal resource 1 and signal resource 2 is adjacent to the time domain position of signal resource 0.

[0211] In some embodiments, Figure 2F can also be interpreted as taking the frequency domain starting position of signal resource 0 as the frequency domain starting position of signal resource 1, taking the adjacent position of the time domain ending position of signal resource 0 as the time domain starting position of signal resource 1, taking the time domain ending position of signal resource 1 as the time domain starting position of signal resource 2, and taking the frequency domain ending position of signal resource 1 as the frequency domain starting position of signal resource 2.

[0212] In some embodiments, the position of the second signal resource may be determined according to the position of the first signal resource, the neighboring relationship between multiple signal resources, and the CDM group type of each signal resource.

[0213] For example, if the CDM group type of the second signal resource is the same as the CDM group type of the first signal resource, the time domain position of the first signal resource can be used as the time domain position of the second signal resource, and the adjacent position of the frequency domain position of the first signal resource can be used as the frequency domain position of the second signal resource; if the CDM group type of the second signal resource is different from the CDM group type of the first signal resource, the frequency domain position of the first signal resource can be used as the frequency domain position of the second signal resource, and the adjacent position of the time domain position of the first signal resource can be used as the time domain position of the second signal resource.

[0214] In some embodiments, the second signal resource may include multiple CDM groups, and the terminal device may use the first position of the first signal resource as the first position of the second CDM group of the second signal resource; determine the adjacent position of the second position of the first signal resource; determine the second position of the second CDM based on the adjacent relationship between the adjacent position and multiple signal resources; and determine the first position and second position of the first CDM group based on the second indication information.

[0215] In some embodiments, if the first position is a time domain position, the time domain position of the first signal resource can be used as the time domain position of the second CDM group of the second signal resource; if the first position is a frequency domain position, the frequency domain position of the first signal resource can be used as the frequency domain position of the second CDM group of the second signal resource.

[0216] In some embodiments, if the first position is the time domain starting position, the time domain starting position of the first signal resource can be used as the time domain starting position of the second CDM group of the second signal resource; if the first position is the frequency domain starting position, the frequency domain starting position of the first signal resource can be used as the frequency domain starting position of the second CDM group of the second signal resource.

[0217] It should be noted that the method for determining the first position and the second position of the second CDM can refer to the above-mentioned method for determining the first position and the second position of the second signal resource, which will not be repeated here.

[0218] In some embodiments, if the second indication information includes the positional relationship between multiple CDM groups of the first signal resource, the terminal device can determine the positional relationship between multiple CDMs in the first CDM group based on the positional relationship between multiple CDM groups of the first signal resource; and determine the first position and second position of each CDM group in the first CDM group based on the positional relationship between multiple CDM groups in the first CDM group.

[0219] In some embodiments, the positional relationship between the multiple CDM groups of the first signal resource may include a position type and / or a position offset between the multiple CDM groups, and the position type may include at least one of FDM, TDM, and CDM.

[0220] In one implementation, if the position type between multiple CDM groups of the first signal resource is FDM, that is, the time domain starting positions of the multiple CDM groups are the same but the frequency domain positions are different, the first position and the second position of the first CDM group can be determined using the FDM method. For example, the time domain starting position of the first CDM group can be the same as the time domain starting position of the second CDM group, and the frequency domain position of the first CDM group is adjacent to the frequency domain position of the second CDM group. That is, for each CDM group in the first CDM group, the time domain position is the same as the time domain starting position of the second CDM group, and the frequency domain positions are adjacent to each other. For example, if the first CDM group includes CDM group 1, CDM group 2, and CDM group 3, the time domain starting positions of CDM group 1, CDM group 2, and CDM group 3 are all the same as the second CDM group, the frequency domain position of CDM group 1 is adjacent to the second CDM group, the frequency domain position of CDM group 2 is adjacent to CDM group 1, and the frequency domain position of CDM group 3 is adjacent to CDM group 2.

[0221] In another implementation, if the position type between the multiple CDM groups of the first signal resource is FDM, that is, the time domain starting positions of the multiple CDM groups are the same but the frequency domain positions are different, the first position and the second position of the first CDM group can be determined using the FDM method based on the position offsets between the multiple CDMs of the first signal resource. For example, the time domain starting position of the first CDM group can be the same as the time domain starting position of the second CDM group, and the frequency domain position of each CDM group in the first CDM group can be determined based on the position offsets between the multiple CDMs of the first CDM group.

[0222] In some embodiments, the position offsets corresponding to CDM groups with the same index in different signal resources may be the same. For example, if the first signal resource includes three CDM groups with indexes of 1, 2, and 3, and the second signal resource includes three CDM groups with indexes of 1, 2, and 3, respectively, CDM group 1 of the second signal resource is the second CDM group, and CDM groups 2 and CDM groups 3 of the second signal resource are the first CDM group, then the position offset of CDM group 2 of the first CDM group can be determined based on the position offset of CDM group 2 of the first signal resource, and the position offset of CDM group 3 of the first CDM group can be determined based on the position offset of CDM group 3 of the first signal resource.

[0223] In some embodiments, if the first CDM group may include multiple ones, the positions of some first CDM groups may be the same as the position of the first signal resource, and the positions of some first CDM groups may be other positions different from the position of the first signal resource.

[0224] It should be noted that the network device may not send the second indication information to the terminal device, the second indication information is predefined, or the second indication information is default information.

[0225] It should also be noted that the above is to determine the position of the first CDM group and the second CDM group of a second signal resource. The position of the first CDM group and the second CDM group of each second signal resource can be determined in the above manner, which will not be repeated here.

[0226] In some embodiments, the first signal resource may include multiple CDM groups, and the terminal device may use the first position of the third CDM group of the first signal resource as the first position of the second signal resource, where the third CDM group is any CDM group among the multiple CDM groups of the first signal resource; determine the adjacent position of the second position of the third CDM group of the first signal resource; and determine the second position of the second signal resource based on the adjacent relationship between the adjacent positions and multiple signal resources.

[0227] In some embodiments, the third CDM group may be the CDM group with the largest index or the CDM group with the smallest index in the first signal resource.

[0228] It should be noted that, the implementation method of determining the first position of the second signal resource according to the first position of the third CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the first position of the second signal resource according to the first position of the first signal resource, the implementation method of determining the adjacent position of the second position of the third CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the adjacent position of the second position of the first signal resource, and the implementation method of determining the second position of the second signal resource according to the second position of the third CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the second position of the second signal resource according to the second position of the first signal resource, which will not be repeated here.

[0229] In some embodiments, if the second signal resource includes multiple CDM groups, the positions of some of the second signal resources can be determined based on the position of the third CDM group of the first signal resource, and the positions of some of the second signal resources can be determined based on the position of the fourth CDM group of the first signal resource. The fourth CDM group can be a CDM group other than the third CDM group among the multiple CDM groups of the first signal resource.

[0230] For example, if the first signal resource includes signal resource 0, which includes CDM group 1 and CDM group 2, and the second signal resource includes signal resource 1 and signal resource 2, the position of signal resource 1 can be determined based on the position of CDM group 1 of signal resource 0, and the position of signal resource 2 can be determined based on the CDM group 2 of signal resource 0.

[0231] It should also be noted that the implementation method of determining the first position of the second signal resource based on the first position of the fourth CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the first position of the second signal resource based on the first position of the first signal resource; the implementation method of determining the adjacent position of the second position of the fourth CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the adjacent position of the second position of the first signal resource; the implementation method of determining the second position of the second signal resource based on the second position of the fourth CDM group of the first signal resource can refer to the above-mentioned implementation method of determining the second position of the second signal resource based on the second position of the first signal resource, and will not be repeated here.

[0232] Using the above method, a terminal device can determine the location of a second signal resource based on the location of the first signal resource indicated by the network device. This allows the network device to only specify the location of the first signal resource, thereby reducing signaling indication overhead. Furthermore, the location of the second signal resource includes a location adjacent to the location of the first signal resource. This ensures time-frequency correlation between multiple channels corresponding to multiple signal resources, thereby improving channel measurement accuracy.

[0233] The method involved in the embodiments of the present disclosure may include at least one of the above steps S2101 and S2102. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments.

[0234] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

[0235] FIG2G is an interactive diagram illustrating a resource configuration method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system. As shown in FIG2G , the method may include:

[0236] Step S2701: The network device sends first information to the terminal device.

[0237] The optional implementation of step S2701 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0238] In some embodiments, the first information may include first indication information, which is used to indicate the location of a first signal resource, where the first signal resource is at least one signal resource among multiple signal resources, and different signal resources are used to measure channels corresponding to different antenna ports.

[0239] Step S2702: The terminal device determines that the first signal resource and the second signal resource belong to the same resource set.

[0240] In some embodiments, if the terminal device determines that the resource information of the first signal resource is the same as the resource information of the second signal resource, it can be determined that the first signal resource and the second signal resource belong to the same resource set.

[0241] In some embodiments, the resource information may include at least one of the following: number of ports, density, starting position of resource blocks, number of resource blocks, CDM group type, wherein the same port index in different resource information has the same subcarrier position or orthogonal frequency division multiplexing OFDM symbol position.

[0242] In some embodiments, the network device may also indicate to the terminal device the identifier of the resource set to which each signal resource belongs, and the terminal device may determine whether the first signal resource and the second signal resource belong to the same resource set based on the identifier of the resource set.

[0243] Step S2703: The terminal device determines, for each second signal resource, a third signal resource corresponding to the second signal resource from the first signal resources according to a specified association relationship, and uses the position of the third signal resource as the position of the second signal resource.

[0244] In some embodiments, the designated association relationship may include a correspondence between different second signal resources and first signal resources.

[0245] For example, if the first signal resource includes signal resource 0 and signal resource 1, and the second signal resource includes signal resource 2 and signal resource 3, the designated association relationship may be that signal resource 0 corresponds to signal resource 2, and signal resource 1 corresponds to signal resource 3.

[0246] In some embodiments, the specified association relationship may be predefined.

[0247] In some embodiments, the designated association relationship may be indicated by a network device.

[0248] In one implementation, the first information may further include fourth indication information, and the fourth indication information may be used to indicate the designated association relationship.

[0249] In some embodiments, if the second signal resource includes one signal resource, the position of any first signal resource may be used as the position of the second signal resource.

[0250] In some embodiments, if the second signal resource includes multiple signal resources, for each second signal resource, the third signal resource corresponding to the second signal resource can be determined from the first signal resource according to the specified association relationship, and the position of the third signal resource can be used as the position of the second signal resource.

[0251] For example, if the designated association relationship is that signal resource 0 corresponds to signal resource 2, and signal resource 1 corresponds to signal resource 3, then for signal resource 2, signal resource 0 can be determined as the third signal resource corresponding to signal resource 2, and the position of signal resource 0 can be used as the position of signal resource 2, signal resource 1 can be determined as the third signal resource corresponding to signal resource 3, and the position of signal resource 0 can be used as the position of signal resource 2.

[0252] In some embodiments, taking the position of the third signal resource as the position of the second signal resource can be interpreted as taking the time domain position of the third signal resource as the time domain position of the second signal resource, and taking the frequency domain position of the third signal resource as the frequency domain position of the second signal resource.

[0253] Using the above method, a terminal device can determine the location of a second signal resource based on the location of the first signal resource indicated by the network device. This allows the network device to only specify the location of the first signal resource, thereby reducing signaling indication overhead. Furthermore, the location of the second signal resource includes the same location as the first signal resource. This ensures time-frequency correlation between multiple channels corresponding to multiple signal resources, thereby improving channel measurement accuracy.

[0254] The method involved in the embodiments of the present disclosure may include at least one of steps S2701 to S2703. For example, step S2701 may be implemented as an independent embodiment, step S2702 may be implemented as an independent embodiment, step S2703 may be implemented as an independent embodiment, and steps S2702+S2703 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0255] In some embodiments, steps S2701 to S2703 are all optional steps. For example, steps S2701 and S2702 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0256] FIG2H is an interactive diagram illustrating a resource configuration method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system. As shown in FIG2H , the method may include:

[0257] Step S2801: The network device sends first information to the terminal device.

[0258] The optional implementation of step S2801 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0259] In some embodiments, the first information may include first indication information, which is used to indicate the location of a first signal resource, where the first signal resource is at least one signal resource among multiple signal resources, and different signal resources are used to measure channels corresponding to different antenna ports.

[0260] Step S2802: The terminal device determines the location of the fourth signal resource by the first method according to the location of the first signal resource.

[0261] In some embodiments, the first mode may be any of the specified modes.

[0262] In some embodiments, the designated method includes at least one of the following: a time domain multiplexing (TDM) method, a frequency domain multiplexing (FDM) method, and a code domain multiplexing (CDM) method.

[0263] In some embodiments, the fourth signal resource may be a portion of the second signal resource.

[0264] In some embodiments, the fourth signal resource may be predefined.

[0265] In some embodiments, the network device may also indicate the fourth signal resource.

[0266] In some embodiments, if the first mode is a TDM mode, the position of the fourth signal resource can be determined by the TDM mode according to the position of the first signal resource.

[0267] In some embodiments, if the first mode is an FDM mode, the position of the fourth signal resource can be determined by the FDM mode according to the position of the first signal resource.

[0268] It should be noted that when determining the position of the fourth signal resource by TDM, the position of the second signal resource can be determined by referring to the first position in step S2102 when it is a frequency domain position. When determining the position of the fourth signal resource by FDM, the position of the second signal resource can be determined by referring to the first position in step S2102 when it is a time domain position.

[0269] In some embodiments, if the first method is a CDM method, the location of the fourth signal resource can be determined by the CDM method according to the location of the first signal resource.

[0270] It should also be noted that, when determining the position of the fourth signal resource by means of CDM, reference can be made to step S2703 for determining the position of the second signal resource.

[0271] Step S2803: The terminal device determines the position of the fifth signal resource by the second method according to the position of the first signal resource and the position of the fourth signal resource.

[0272] In some embodiments, the second mode may be at least one of the designated modes except the first mode.

[0273] For example, if the first mode is the FDM mode, the second mode may be the TDM mode and / or the CDM mode; if the first mode is the TDM mode, the second mode may be the FDM mode and / or the CDM mode; if the first mode is the CDM mode, the second mode may be the TDM mode and / or the FDM mode.

[0274] In some embodiments, the fifth signal resource may be a signal resource in the second signal resource excluding the fourth signal resource.

[0275] In some embodiments, after the terminal device determines the location of the fourth signal resource by the first method, it can determine the location of the fifth signal resource by the second method based on the location of the first signal resource and the location of the fourth signal resource.

[0276] Figure 2I is a schematic diagram illustrating signal resource locations according to an embodiment of the present disclosure. As shown in Figure 2I , signal resource 0 is the first signal resource, signal resource 1 is the fourth signal resource, and signal resources 2 and 3 are the fifth signal resources. A terminal device can determine the location of signal resource 1 using TDM based on the location of signal resource 0, and can determine the locations of signal resources 2 and 3 using FDM based on the locations of signal resources 0 and 1.

[0277] In some embodiments, the terminal device may determine the location of the sixth signal resource by the third method and determine the location of the seventh signal resource by the fourth method based on the location of the first signal resource and the location of the fourth signal resource.

[0278] In some embodiments, the third mode may be any mode in the second mode, and the fourth mode may be a mode in the second mode that is different from the third mode.

[0279] In some embodiments, the sixth signal resource may be a portion of the fifth signal resource, and the seventh signal resource may be a signal resource in the fifth signal resource excluding the sixth signal resource.

[0280] For example, if the second mode is FDM and TDM, the third mode may be FDM, the fourth mode may be TDM, the position of the sixth signal resource may be determined by FDM, and the position of the seventh signal resource may be determined by TDM.

[0281] FIG2J is a schematic diagram illustrating a signal resource location according to an embodiment of the present disclosure. As shown in FIG2J , signal resource 0 is the first signal resource, signal resource 1 is the fourth signal resource, signal resources 2 and signal resources 3 are the sixth signal resources, and signal resource 4 is the seventh signal resource. The terminal device may determine the location of signal resource 1 by TDM based on the location of signal resource 0, determine the locations of signal resources 2 and signal resources 3 by FDM based on the locations of signal resources 0 and signal resource 1, and determine the location of signal resource 4 by CDM based on the location of signal resource 0 (the location of signal resource 4 is the same as that of signal resource 0, and optionally, the location of signal resource 4 may be the same as that of the RE of signal resource 0).

[0282] Using the above method, a terminal device can determine the location of a second signal resource based on the location of the first signal resource indicated by the network device. In this way, the network device only needs to specify the location of the first signal resource, thereby reducing signaling indication overhead. Furthermore, the location of the second signal resource includes a location that is the same as and / or adjacent to the location of the first signal resource. This ensures time-frequency correlation between multiple channels corresponding to multiple signal resources, thereby improving channel measurement accuracy.

As shown in Figure 5, the embodiment of the present disclosure relates to a resource configuration method, which can be executed by a communication system. The method may include:

[0397] The second signal resource is a signal resource other than the first signal resource among the multiple signal resources, and the position of the second signal resource includes a position that is the same as and / or adjacent to the position of the first signal resource.

[0398] In some embodiments, the above method may include the method described in the embodiments of the above communication system, terminal equipment, network equipment, etc., which will not be repeated here.

[0399] In some embodiments, by combining FDM / TDM / CDM, N (N>1) CSI-RS resources are configured in an aggregated manner in the time domain, frequency domain and / or code domain to support channel measurement of larger antenna ports while ensuring channel measurement accuracy.

[0400] In some embodiments, N (N>1) CSI-RS resources with the same or different number of ports are configured, and the N CSI-RS resources use the same or different CDM groups. These N CSI-RS resources come from M (M≥1) CSI-RS resource sets. If M=1, then for the N CSI-RS resources from the M CSI-RS resource sets, the N CSI-RS resources have the same number of ports, density, resource block (RB) starting position, number of RBs, and CDM pattern type; if M>1, then for the N CSI-RS resources from the M CSI-RS resource sets, the number of ports, density, RB starting position, number of RBs, and CDM pattern type of the N CSI-RS resources may be different.

[0401] In some embodiments, the network device may send N CSI-RS resources via FDM / TDM / CDM.

[0402] In some embodiments, a reference CSI-RS resource is defined within one or multiple adjacent PRBs, and N-1 CSI-RS resources and the reference CSI-RS resource are mapped on adjacent frequency domains.

[0403] In some embodiments, the position indication of the CSI-RS resource mapped to the resource element (RE) is as follows: only the time domain and frequency domain starting positions of the reference CSI-RS resource are indicated, the time domain starting position of the other N-1 CSI-RS resources is the same as the time domain starting position of the reference CSI-RS resource, and the frequency domain starting position of the N-1 CSI-RS resources is determined based on the indicated frequency domain starting position of the reference CSI-RS resource or the frequency domain starting position of a CDM pattern in the reference CSI-RS resource, the CDM type, and the adjacent relationship between the N-1 CSI-RS resources and the reference CSI-RS resource.

[0404] In some embodiments, a reference CSI-RS resource is defined in one or more adjacent time slots, and N-1 CSI-RS resources and the reference CSI-RS resource are mapped in adjacent time domains.

[0405] In some embodiments, the position indication of the CSI-RS resource mapped to the RE is: only the time domain and frequency domain starting positions of the reference CSI-RS resource are indicated, the frequency domain starting positions of the other N-1 CSI-RS resources are the same as the frequency domain starting position of the reference CSI-RS resource, and the time domain starting positions of the N-1 CSI-RS resources are determined based on the indicated time domain starting position of the reference CSI-RS resource or the time domain starting position of a CDM pattern in the reference CSI-RS resource, the CDM type and the adjacent relationship between the N-1 CSI-RS resources and the reference CSI-RS resource.

[0406] In some embodiments, N resources come from a CSI-RS resource set, a reference CSI-RS resource is defined, and the N-1 CSI-RS resources and the reference CSI-RS resource are mapped to the same time-frequency domain position.

[0407] In some embodiments, the position indication of the CSI-RS resource mapped to the RE is: only the time domain and frequency domain starting position of the reference CSI-RS resource is indicated, and the frequency domain and time domain starting positions of the other N-1 CSI-RS resources are the same as the frequency domain and time domain starting positions of the reference CSI-RS resource.

[0408] In some embodiments, N CSI-RS resources are sent by combining any two or three of FDM / TDM / CDM.

[0409] In one implementation, a reference CSI-RS resource is defined within one or multiple adjacent PRBs, or within one or more adjacent time slots. The time-frequency domain mapping position of the reference CSI-RS resource is used as a reference, and N CSI-RS resources are mapped in the order of first the frequency domain and then the time domain.

[0410] In another implementation, a reference CSI-RS resource is defined within one or multiple adjacent PRBs, or within one or more adjacent time slots, and N CSI-RS resources are mapped in the order of first the time domain and then the frequency domain, using the time-frequency domain mapping position of the reference CSI-RS resource as a reference.

[0411] In some embodiments, the position indication of the CSI-RS resource mapped to the RE is: indicating the time domain and frequency domain starting position of the reference CSI-RS resource, and the frequency domain and time domain starting positions of the other N-1 CSI-RS resources are determined based on the indicated reference CSI-RS time-frequency domain starting position or the time-frequency domain starting position of a CDM pattern in the reference CSI-RS resource, the CDM type of the N-1 resources and the mapping rules described in the above two implementation methods.

[0412] It should be noted that for FDM / TDM, or a combination of FDM and TDM, if the reference CSI-RS resource contains multiple CDM groups and the CDM groups are not adjacent in the time or frequency domain, then the other N-1 resources are adjacent in the frequency and / or time domain to the time-frequency domain location of a predefined CDM group in the reference CSI-RS resource. The predefined CDM group can be the first or last CDM group.

[0413] Example 1 (FDM method):

[0414] If N = 2 or 3, the gNB configures a CSI-RS resource set for the UE. This resource set contains two CSI-RS resources with the same number of ports, CSI-RS resource density, CDM type, RB starting position, and bandwidth. If the configured CSI-RS resource IDs are 0 and 1, respectively, the CSI-RS resource with ID = 0 (signal resource 0) is defined as the first CSI-RS resource, the CSI-RS resource with ID = 1 (signal resource 1) is defined as the second CSI-RS resource, and the CSI-RS resource with the smallest resource ID, ID = 0, is defined as the reference resource.

[0415] The two CSI-RS resources have the same time domain position and are adjacent in the frequency domain. As shown in Figure 2C , the gNB only configures the starting position of the time and frequency domain for the CSI-RS resource with ID = 0. The time and frequency domain position of the CSI-RS resource with ID = 1 can be determined based on the time and frequency domain position of the CSI-RS resource with ID = 0, without the need for additional signaling. If ID = 0 is composed of multiple CDM patterns that are not adjacent in the frequency domain, the time and frequency domain position of ID = 1 is determined based on the position of one of the CDM patterns. For example, the frequency domain position of ID = 1 is determined based on the frequency domain position of the CDM pattern with the largest index and the CDM type.

[0416] If the gNB configures N (N=3) CSI-RS resources for the UE, with CSI-RS resource IDs 0, 1, and 2, respectively, indexed in ascending order by ID value as 1, 2, and 3, these three resources come from two CSI-RS resource sets: CSI-RS resource ID 0 comes from CSI-RS resource set 1, while CSI-RS resources ID 1 and ID 2 come from CSI-RS resource set 2. When configuring CDM patterns for resources ID 1 and ID 2, in case 1, the CDM pattern is the same as the CDM pattern for ID 0; in case 2, the number of time-domain REs in the CDM pattern for ID 0 is twice the number of time-domain REs in the CDM pattern for ID 1 and ID 2. For case 1, the frequency domain positions of the CSI-RS resource with ID = 1 (signal resource 1) and the CSI-RS resource with ID = 0 (signal resource 0) are adjacent, while the frequency domain position of the CSI-RS resource with ID = 2 (signal resource 2) is adjacent to the frequency domain position of the CSI-RS resource with ID = 1. For case 2, the frequency domain positions of the CSI-RS resource with ID = 1 (signal resource 1) and the CSI-RS resource with ID = 2 (signal resource 2) are adjacent to the frequency domain position of the CSI-RS resource with ID = 0 (signal resource 0), as shown in Figure 2D.

[0417] Example 2 (TDM method):

[0418] Similar to Example 1, the gNB configures N (N = 2 or 3) CSI-RS resources for the UE. When N = 2, the two CSI-RS resources have the same frequency domain location but different time domain locations. If the CSI-RS resource with ID = 0 is used as the reference CSI-RS resource, the gNB indicates the time-frequency domain location of the CSI-RS resource with ID = 0 through RRC signaling. The time domain location of the CSI-RS resource with ID = 1 is adjacent to the time domain location of the CSI-RS resource with ID = 0, as shown in the left figure of Figure 3. Optionally, the time domain location of the CSI-RS resource with ID = 1 may be located to the left of the time domain location of the CSI-RS resource with ID = 0 and adjacent to it. If the CSI-RS resource with ID = 0 contains multiple CDM patterns, the time domain location of the CSI-RS resource with ID = 1 is adjacent to the time domain location of one of the CDM patterns in the CSI-RS resource with ID = 0. For example, the one CDM pattern is defined as the CDM pattern with the smallest index among the CDM patterns.

[0419] When N=3, similar to Example 1, the frequency domain positions of these three CSI-RS resources are the same, while the time domain position of the CSI-RS resource with ID=1 is adjacent to the position of the reference CSI-RS resource with ID=0, and the time domain position of the CSI-RS resource with ID=2 is adjacent to the time domain position of the CSI-RS resource with ID=1, as shown in Figure 2E. Optionally, the time domain position of the CSI-RS resource with ID=2 (signal resource 2) is adjacent to the time domain position of the CSI-RS resource with ID=0 (signal resource 0) and is located to the left of the time domain position of the CSI-RS resource with ID=0 (signal resource 0).

[0420] If the multiple CDM patterns of the CSI-RS resource with ID=0 are not adjacent in the time domain, the positions of the CSI-RS resources with ID=1 and ID=2 can be determined based on the time domain position of one of the CDM patterns of the CSI-RS resource with ID=0, for example, adjacent to the time domain position of the CDM pattern with the largest index. Optionally, the positions of the CSI-RS resources with ID=1 and ID=2 can be determined based on the time domain positions of multiple CDM patterns of the CSI-RS resource with ID=0, such as the time domain position of the CSI-RS resource with ID=1 is adjacent to the time domain position of the CDM pattern with the largest index in the CSI-RS resource with ID=0, and the time domain position of the CSI-RS resource with ID=2 is adjacent to the time domain position of the CDM pattern with the smallest index in the CSI-RS resource with ID=0.

[0421] Example 3 (combination of FDM and TDM):

[0422] If the gNB configures N (N=4) CSI-RS resources for the UE, with resource IDs 0, 1, 2, and 3, the four CSI-RS resources are sorted in ascending order of ID. These four resources come from the same CSI-RS resource set and have the same CDM pattern, frequency domain density, RB starting position, number of CSI-RS ports, and bandwidth. The configuration method of these four CSI-RS resources can be to first configure two CSI-RS resources in the time domain, such as configuring the CSI-RS resource with ID=0 (signal resource 0) and the CSI-RS resource with ID=1 (signal resource 1), and then using the time domain positions of the CSI-RS resource with ID=0 (signal resource 0) and the CSI-RS resource with ID=1 (signal resource 1) as a reference, configure the CSI-RS resource with ID=2 (signal resource 2) and the CSI-RS resource with ID=3 (signal resource 3) at frequency domain positions adjacent to the CSI-RS resource with ID=0 (signal resource 0) and the CSI-RS resource with ID=1 (signal resource 1), as shown in Figure 2I.

[0423] Define the CSI-RS resource with ID = 0 as the reference CSI-RS resource. According to the predefined rules above, the gNB only needs to indicate the time-frequency domain position of the CSI-RS resource with ID = 0. The time-frequency domain positions of the other three CSI-RS resources are determined based on this predefined rule.
