[0139] Figure 1 is a communication system architecture diagram shown according to the embodiments of the present disclosure.

[0140] As shown in Figure 1 , the communication system 100 includes a terminal 101 and a network device 102.

[0141] In some embodiments, the network device 102 can include at least one of an access network device and a core network device.

[0142] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network, and the access network device can include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an Open RAN, a Cloud RAN, a base station in other communication systems, an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0143] In some embodiments, the technical solutions of the present disclosure can be applied to an Open RAN architecture, at this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized through software or programs.

[0144] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, with some protocol layer functions being controlled by the CU and the rest or all protocol layer functions being distributed in the DU and controlled by the CU, but is not limited thereto.

[0145] In some embodiments, the core network device can be one device including one or more network elements, or can be multiple devices or device groups including all or part of an evolved packet core (EPC), a 5G core network (5GCN), or a next generation core (NGC). The network element can be virtual or physical.

[0146] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, as the system architecture evolves and new business scenarios appear, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0147] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100 shown is an example, and the communication system can include Figure 1 The communication system can include all or part of the subjects shown in Figure 1 The communication system can include all or part of the subjects shown in Figure 1 In addition to the subjects shown, the communication system can include other subjects, and the number and form of the subjects are arbitrary. The connection relationship between the subjects is an example, and the subjects can be connected or not connected. The connection can be in any manner, can be direct or indirect, and can be wired or wireless.

[0148] 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 (Bluetooth (registered trademark)), public land mobile network (PLMN) network, device-to-device (D2D) system, machine to machine (M2M) system, internet of things (IoT) system, vehicle-to-everything (V2X), system using other communication methods, next-generation system expanded based on them, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0149] In the embodiments of the present disclosure, the network device can provide services for the terminal using 4 TRPs, and the network device can configure N CSI-RS resources in one channel measurement resource (CMR). That is, the network device indicates N TRPs. At the same time, the network device also needs to configure the number of beams to be selected for each CSI-RS resource (that is, for each TRP). It can be understood that the beam can be referred to as a space domain basis (SD basis). That is, M beam combinations are configured by the RRC signaling of the network device, and each beam combination includes the number of beams corresponding to each CSI-RS resource.

[0150] It should be understood that the beam in the present disclosure can be equivalent to the SD basis.

[0151] The above SD basis is related to the number of ports of the CSI-RS resource, such as N1, N2, O1 and O2. N1 represents the number of ports in the first dimension; N2 represents the number of ports in the second dimension; O1 represents the number of oversampling (or oversampling rate) in the first dimension; and O2 represents the number of oversampling (or oversampling rate) in the second dimension. The first dimension may, for example, be the horizontal dimension, and the second dimension may, for example, be the vertical dimension.

[0152] In the embodiments of the present disclosure, the following partial beam combination modes are provided. As shown in Table 1,

[0153]

[0154]

[0155] Table 1

[0156] Wherein, N TRP represents the number of TRPs, and can also represent the number of CSI-RS resources included in one CMR. L n represents the number of beams corresponding to each TRP or CSI-RS resource.

[0157] As can be seen from Table 1, when N TRP is greater than 2, the number of beams of at least one TRP is not currently supported. At the same time, the number of beam combinations that the terminal can maintain at the same time can be 1, 2 or 4. That is, the terminal needs to select one beam combination from 1, 2 or 4 beam combinations and report it to the network device. Based on Table 1, when N TRPWhen the number of beam combinations is 3, the number of configurable beam combinations is already greater than 4. If the number of beams supporting at least one TRP is 6, the number of configurable beam combinations supported is even greater. Therefore, how to configure the beam combinations that the terminal needs to maintain simultaneously is a problem that needs to be solved.

[0158] Of course, it is understandable that in some embodiments, when the number of beam combinations is 1, the terminal may not report.

[0159] Figure 2a FIG. 1 is an interactive diagram of a beam combination determination method according to an embodiment of the present disclosure. Figure 2a As shown, the embodiment of the present disclosure relates to a beam combination determination method, which is used in a communication system 100. The method includes:

[0160] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0161] In some embodiments, terminal 101 receives first information sent by network device 102 .

[0162] In some embodiments, the first information is, for example, “instruction information”, “configuration information”, etc. The present disclosure does not limit the name of the first information.

[0163] In some embodiments, the first information may be RRC signaling.

[0164] In some embodiments, the first information is used to indicate a first number of beam combinations.

[0165] In some embodiments, the beam combination in the present disclosure may also be referred to as a spatial basis vector combination, a beam quantity combination, a spatial basis vector quantity combination, etc. The present disclosure does not limit the name of the beam combination.

[0166] It is understood that in the subsequent embodiments of the present disclosure, the term "beam combination" will be used to describe the subsequent embodiments. However, it should be understood that beam combination can also be replaced by any of the above names.

[0167] In some embodiments, the network device 102 sends RRC signaling. The RRC signaling includes the first information. Optionally, the terminal 101 receives the RRC signaling.

[0168] In some embodiments, the terminal may determine the number of CSI-RS resources in a CMR.

[0169] In some embodiments, the first information is used to indicate the number of CSI-RS resources. The first information is also used to indicate a first number of beam combinations.

[0170] For example, the terminal receives RRC signaling, the RRC signaling indicates the first quantity of beam combinations, and indicates the quantity of CSI-RS resources.

[0171] In some embodiments, the terminal can receive eighth information for indicating the quantity of CSI-RS resources. The eighth information is different from the first information.

[0172] It can be understood that in various embodiments of the present disclosure, the CSI-RS resources involved can be CSI-RS resources in a CMR. In various embodiments of the present disclosure, the quantity of CSI-RS resources involved can refer to the quantity of CSI-RS resources in a CMR.

[0173] In some embodiments, the beam combination includes one or more beam quantities. Each beam quantity can correspond to a CSI-RS resource.

[0174] In some embodiments, the quantity of CSI-RS resources is different, and the maximum value of the first quantity is the same.

[0175] Optionally, when the quantity of CSI-RS resources is different, the maximum value of the first quantity is the same.

[0176] Optionally, when the quantity of CSI-RS resources is different, the maximum value of the first quantity is the same.

[0177] Optionally, in response to the quantity of CSI-RS resources being different, the maximum value of the first quantity is the same.

[0178] For example, when the CSI-RS resource is 1, the maximum value of the first quantity can be 4. When the CSI-RS resource is greater than 1, the maximum value of the first quantity can also be 4.

[0179] In some embodiments, the quantity of CSI-RS resources is different, and the maximum value of the first quantity is different.

[0180] Optionally, when the quantity of CSI-RS resources is different, the maximum value of the first quantity is different.

[0181] Optionally, when the quantity of CSI-RS resources is different, the maximum value of the first quantity is different.

[0182] Optionally, in response to the quantity of CSI-RS resources being different, the maximum value of the first quantity is different.

[0183] For example, when the CSI-RS resource is 1, the maximum value of the first quantity can be 2. When the CSI-RS resource is greater than 1, the maximum value of the first quantity can be 4.

[0184] In some embodiments, the beam combination includes one or more beam quantities, wherein each beam quantity may correspond to a TRP.

[0185] In some embodiments, the number of TRPs is different and the maximum value of the first number is the same.

[0186] Optionally, when the number of TRPs is different, the maximum value of the first number is the same.

[0187] Optionally, when the number of TRPs is different, the maximum value of the first number is the same.

[0188] Optionally, in response to different numbers of TRPs, the maximum value of the first number is the same.

[0189] For example, when the number of TRPs is 1, the maximum value of the first number may be 4. When the number of TRPs is greater than 1, the maximum value of the first number may also be 4.

[0190] In some embodiments, the number of TRPs is different and the maximum value of the first number is different.

[0191] Optionally, when the number of TRPs is different, the maximum value of the first number is different.

[0192] Optionally, when the number of TRPs is different, the maximum value of the first number is different.

[0193] Optionally, in response to different numbers of TRPs, the maximum value of the first number is different.

[0194] For example, when the number of TRPs is 1, the maximum value of the first number may be 2. When the number of TRPs is greater than 1, the maximum value of the first number may be 4.

[0195] In some embodiments, the number of CSI-RS resources is greater than one, and the beam combination includes multiple beam quantities. The multiple beam quantities in the beam combination are associated with the multiple CSI-RS resources in a preset order.

[0196] Optionally, when the number of CSI-RS resources is greater than one, the beam combination includes multiple beam quantities. The multiple beam quantities in the beam combination are associated with the multiple CSI-RS resources in a preset order.

[0197] Optionally, when the number of CSI-RS resources is greater than one, the beam combination includes multiple beam quantities. The multiple beam quantities in the beam combination are associated with the multiple CSI-RS resources according to a preset order.

[0198] Optionally, in response to the CSI-RS resource being greater than one, the beam combination includes multiple beam quantities. The multiple beam quantities in the beam combination are associated with the multiple CSI-RS resources in a preset order.

[0199] For example, in Table 1, when there are four CSI-RS resources, there are multiple beam combinations. For example, consider the beam combination of {2, 2, 2, 4}. This means that one CSI-RS resource corresponds to four beams, while the remaining CSI-RS resources correspond to two beams. How do the numbers of beams in each beam combination correspond to the four CSI-RS resources in a CMR? The corresponding number of beams in the beam combination can be determined based on a preset order to determine which of the four CSI-RS resources corresponds to each CSI-RS resource.

[0200] For example, the preset order can be based on the size of the CSI-RS resource identifier, in descending order. That is, 4 in the beam combination {2, 2, 2, 4} corresponds to the CSI-RS resource with the smallest CSI-RS resource identifier. For another example, the preset order can be based on the size of the CSI-RS resource identifier, in descending order. That is, 4 in the beam combination {2, 2, 2, 4} corresponds to the CSI-RS resource with the largest CSI-RS resource identifier. For another example, a suitable order can be predefined based on the CSI-RS resource identifier. The specific setting can be based on actual conditions and is not limited by this disclosure.

[0201] The identifier may be an identity (ID) or an index.

[0202] In step S2102, the terminal 101 determines a first number of beam combinations based on the first information.

[0203] In some embodiments, the terminal 101 receives the first information and determines the first number of beam combinations indicated by the first information.

[0204] In some embodiments, terminal 101 receives RRC signaling that configures one or more beam combinations. Terminal 101 uses the one or more beam combinations configured by the RRC signaling as the first number of beam combinations. It should be understood that in various embodiments of the present disclosure, "configure" and "indicate" can be used interchangeably.

[0205] For example, terminal 101 receives RRC signaling, and the RRC signaling is configured with 1 beam combination. Terminal 101 uses the 1 beam combination configured by the RRC signaling as the first number of beam combinations. For another example, terminal 101 receives RRC signaling, and the RRC signaling is configured with 2 beam combinations. Terminal 101 uses the 2 beam combinations configured by the RRC signaling as the first number of beam combinations. For another example, terminal 101 receives RRC signaling, and the RRC signaling is configured with 4 beam combinations. Terminal 101 uses the 4 beam combinations configured by the RRC signaling as the first number of beam combinations. It can be understood that terminal 101 can use all beam combinations configured in the RRC signaling as the first number of beam combinations.

[0206] In step S2103, the terminal 101 sends sixth information to the network device 102.

[0207] In some embodiments, the network device 102 receives the sixth information sent by the terminal 101.

[0208] In some embodiments, the sixth information is, for example, “uplink control information (UCI)”, “CSI report”, “CSI measurement report”, “measurement report”, “feedback information”, “report information”, etc.

[0209] In some embodiments, the sixth information can include a precoding matrix indicator (PMI).

[0210] In some embodiments, the sixth information can include a channel quality indicator (CQI).

[0211] In some embodiments, the sixth information can include a rank indicator (RI).

[0212] In some embodiments, the sixth information can include a layer indicator (LI).

[0213] In some embodiments, the sixth information can include at least one of the PMI, the CQI, the RI, and the LI.

[0214] In some embodiments, the sixth information is used to “indicate one beam combination in the first quantity of beam combinations”.

[0215] In some embodiments, the sixth information is used to “indicate multiple beam combinations in the first quantity of beam combinations”.

[0216] It can be understood that the beam combination indicated by the sixth information can be the beam combination corresponding to at least one of the PMI, the CQI, the RI, and the LI reported by the terminal 101. Of course, the name of the sixth information is not limited in the present disclosure.

[0217] In some embodiments, the sixth information generally indicates one beam combination.

[0218] In some embodiments, the terminal 101 sends UCI. The above-mentioned UCI includes the sixth information. Optionally, the network device 102 receives the above-mentioned UCI.

[0219] In some embodiments, the number of bits in the sixth information for indicating one of the first number of beam combinations can be determined according to the first number or a maximum value of the first number.

[0220] The number of bits can also be referred to as bit overhead, bit number, etc., and the name is not limited.

[0221] For example, if the first number is 4, the number of bits in the sixth information for indicating one of the first number of beam combinations can be 2 bits. For another example, if the maximum value of the first number is 4, the number of bits in the sixth information for indicating one of the first number of beam combinations can be 2 bits. For another example, if the first number is 2, the number of bits in the sixth information for indicating one of the first number of beam combinations can be 1 bit. For another example, if the maximum value of the first number is 2, the number of bits in the sixth information for indicating one of the first number of beam combinations can be 1 bit.

[0222] In some embodiments, X bits are included in the UCI. The X bits are used to indicate one of the first number of beam combinations. X can be determined based on the first number or a maximum value of the first number. For example, if the first number or the maximum value of the first number is 4, X can be 2. For another example, if the first number or the maximum value of the first number is 2, X can be 1.

[0223] For example, if the first number or the maximum value of the first number is 2, it means that there are two beam combinations or at most two beam combinations. Therefore, 1 bit can be used to indicate the two beam combinations. For example, the bit value of the 1 bit is 0 or 1. For another example, if the first number or the maximum value of the first number is 4, it means that there are 4 beam combinations or at most 4 beam combinations. Therefore, 2 bits can be used to indicate the 4 beam combinations. For example, the bit value of the 2 bits is 00, 01, 10 or 11.

[0224] Of course, the specific bit value corresponding to which beam combination can be set according to the actual situation, and the present disclosure is not limited.

[0225] In step S2104, the terminal 101 sends the seventh information to the network device 102.

[0226] In some embodiments, the network device 102 receives the seventh information sent by the terminal 101.

[0227] In some embodiments, the seventh information is, for example, "indication information", "feedback information", "reporting information", "capability information", "terminal capability information", "capability report", "terminal capability report", "capability reporting information", "terminal capability reporting information", "capability feedback information", "terminal capability feedback information", and the like.

[0228] In some embodiments, the seventh information can include the capability of the maximum value of the first number supported by the terminal.

[0229] In some embodiments, the seventh information is used to indicate the maximum value of the first number supported by the terminal.

[0230] In some embodiments, the seventh information can be information used to indicate the maximum value of the first number supported by the terminal.

[0231] In some embodiments, the seventh information can indicate the maximum value of the first number supported by the terminal.

[0232] For example, the terminal can support the same maximum value of the first number for different CSI-RS resource numbers. Therefore, this value can be taken as the maximum value of the first number supported by the terminal. For example, when the CSI-RS resource number is 1 or the CSI-RS resource number is greater than 1, the maximum value of the first number supported by the terminal can be 4. Wherein, the CSI-RS resource number can be the number of CSI-RS resources contained in a CMR.

[0233] For example, the terminal can support the same maximum value of the first number for different TRP numbers. Therefore, this value can be taken as the maximum value of the first number supported by the terminal. For example, when the TRP number is 1 or the TRP number is greater than 1, the maximum value of the first number supported by the terminal can be 4.

[0234] In some embodiments, the seventh information can indicate the maximum values of multiple first numbers supported by the terminal.

[0235] For example, the terminal can support different maximum values of the first number for different CSI-RS resource numbers, respectively. Therefore, the maximum values of the first number supported by the terminal in the case of different CSI-RS resource numbers can be indicated respectively. For example, when the CSI-RS resource number is 1, the maximum value of the first number supported by the terminal can be 2. When the CSI-RS resource number is greater than 1, the maximum value of the first number supported by the terminal can be 4. Wherein, the CSI-RS resource number can be the number of CSI-RS resources contained in a CMR.

[0236] For example, the terminal can support different maximum values of the first number for different TRP numbers. Therefore, the terminal can be respectively indicated to support the maximum values of the first number in the case of different TRP numbers. For example, when the TRP number is 1, the terminal can support a maximum value of the first number of 2. When the TRP number is greater than 1, the terminal can support a maximum value of the first number of 4.

[0237] In some embodiments, step S2104 can be performed before step S2101.

[0265] In some embodiments, the terminal may receive eighth information, where the eighth information is used to indicate the number of CSI-RS resources. The eighth information is different from the third information.

[0266] Step S2203: Terminal 101 determines the first information based on the second information and the third information.

[0267] Optional implementations of step S2203 can be found in Figure 2a Optional implementation of step S2102, and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

It can be understood that the RRC signaling configures the second number of beam combinations. The terminal 101 receives the MAC CE, and activates the first number of beam combinations from the second number of beam combinations through the MAC CE.

[0271] For example, the terminal 101 receives the RRC signaling, and the RRC signaling is configured with 5 beam combinations. The terminal 101 receives the MAC CE, and the MAC CE activates 4 beam combinations from the 5 beam combinations configured by the RRC signaling.

[0272] In some embodiments, the terminal 101 receives the RRC signaling, and the terminal 101 can determine the second number of beam combinations according to the RRC signaling.

The terminal 101 receives the DCI, and the first field of the DCI can indicate one code point from the plurality of code points. So that the terminal 101 can determine the first number of beam combinations corresponding to the code point indicated by the DCI.

Among the 4 beam combinations corresponding to the code point 1 and the 4 beam combinations corresponding to the code point 2, there can be 3 same beam combinations. The terminal 101 receives the DCI, and the first field of the DCI indicates one code point, for example, code point 2. Then the terminal can determine the 4 beam combinations corresponding to the code point 2 according to the code point 2 in the DCI.

[0276] In some embodiments, if the second number of beam combinations includes the first number of beam combinations corresponding to one code point in the first field, the DCI can not be needed for indication.

[0322] Optional implementation of step S2303 can refer to the optional implementation of step S2101 in the embodiments described in Figure 2b and the other parts of the embodiments described in Figure 2b which are relevant. Optional implementation of step S2303 can also refer to the optional implementation of step S2202 in the embodiments described in Figure 2a and the other parts of the embodiments described in Figure 2a which are relevant.
