[0056] The example embodiments will be described in detail herein with reference to the accompanying drawings. The following description is presented with reference to the accompanying drawings, in which a similar reference number is used throughout different drawings to refer to similar, but not necessarily identical, elements. The embodiments described in the following example embodiments are not meant to represent all embodiments consistent with the present disclosure.

[0057] The communication method consistent with the present disclosure can be applied in a wireless communication system 100 as shown in FIG. 1. The network system can include a network device 110 and a terminal 120. It can be understood that the wireless communication system shown in FIG. 1 is only illustrative, and other network devices can also be included in the wireless communication system, such as core network devices, wireless relay devices, and wireless backhaul devices, etc., which are not shown in FIG. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

[0058] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier-frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance, and the like. Depending on the capacity, rate, latency, and the like of different networks, the networks can be classified into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks, such as the 5th generation wireless communication system (5G) network. The 5G network can also be referred to as NR. For the convenience of description, the wireless communication network can be referred to as a network in the present disclosure.

[0059] Further, the network device 110 involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or TRP, and the like. It can also be a gNB in an NR system, or it can also be a component or part of a device that constitutes a base station, and the like. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form of the network device are not limited in the embodiments of the present disclosure.

[0060] Further, the terminal 120 involved in the present disclosure, which can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users, for example, the terminal can be a handheld device having wireless connection function, a vehicle-mounted device, etc. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the present disclosure does not limit the specific technology and specific device form of the terminal.

[0061] In the embodiments of the present disclosure, the network device 110 and the terminal 120 can use any feasible wireless communication technology to realize mutual transmission of data. Wherein, the transmission channel corresponding to the data transmitted by the network device 110 to the terminal 120 is called downlink (DL), and the transmission channel corresponding to the data transmitted by the terminal 120 to the network device 110 is called uplink (UL). It can be understood that the network device involved in the embodiments of the present disclosure can be a base station. Of course, the network device can also be any other possible network device, and the terminal can be any possible terminal, which is not limited by the present disclosure.

[0062] In some schemes, the network device can use 4 TRPs to provide services for the terminal. In some schemes, the network device can configure K CSI-RS resources in one channel measurement resource (CMR), that is, the network device indicates K TRPs, K is a positive integer. At the same time, the network device also needs to configure the number of beams to be selected for each CSI-RS resource (i.e., for each TRP). It can be understood that the beam can be referred to as a space domain basis (SD basis). That is, a plurality of beam combinations are configured by radio resource control (RRC) signaling of the network device, and each beam combination contains the number of beams corresponding to each CSI-RS resource.

[0063] It should be understood that the beam in the present disclosure can be replaced by SD basis.

[0064] In some embodiments, the terms “uplink,” “uplink,” “physical uplink,” and the like can be replaced with each other, the terms “downlink,” “downlink,” “physical downlink,” and the like can be replaced with each other, and the terms “side,” “sidelink,” “sidelink communication,” “sidelink communication,” “direct connection,” “direct connection link,” “direct connection communication,” “direct connection link communication,” and the like can be replaced with each other.

[0065] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” “UL DCI,” and the like can be replaced with each other.

[0066] wherein the SD basis above 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 oversampling number (or oversampling rate) in the first dimension; and O2 represents the oversampling number (or oversampling rate) in the second dimension. The first dimension can be, for example, the horizontal dimension, and the second dimension can be, for example, the vertical dimension.

[0067] In the embodiments of the present disclosure, the following partial beam combination modes are provided. As shown in Table 1,

[0068] Table 1

[0069] 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.

[0070] As can be seen from Table 1, 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. Of course, it can be understood that in some embodiments, when the number of beam combinations is 1, the terminal can not report.

[0071] It can be understood that each element in Table 1 exists independently, and the elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 is an independent embodiment.

[0072] Meanwhile, the number of frequency domain basis (FD basis) parameters can be denoted as P v , and the non-zero coefficient parameter can be denoted as β. For the combination of SD basis and the combination of P v and β, reference can be made to Table 2.

[0073] Table 2

[0074] wherein, "w / restriction" means that the rank can be at most 2. "N / A" can be understood as not applicable. It can be seen that the combination of SD basis and the combination of P v and β in Table 2 are all empty, indicating that there is no conclusion at present. Meanwhile, there are four P v in the combination of P v in Table 2. That is, the maximum rank is 4. In the case of rank 4, there are four layers, and each layer corresponds to a P v . The P v on different layers is used to determine the number of frequency domain basis vectors to be selected on the corresponding layer. The number of frequency domain basis vectors to be selected can be determined by multiplying the total number of frequency domain basis vectors by P v .

[0075] It can be understood that each element in Table 2 exists independently, and the elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in Table 2. Therefore, those skilled in the art can understand that the value of each element in Table 2 is an independent embodiment.

[0076] However, in some schemes, one parameter combination identifier can correspond to one SD basis combination, one P v and one β at the same time. Therefore, the network device only needs to configure one parameter combination identifier.

[0077] However, for a certain number of TRPs, the network device can configure the SD basis combination as 1, 2, or 4. Each combination corresponds to P v , β. And assuming that the number of TRPs is 3, the network device can configure the SD basis combination as {4, 4, 4}, for example. The network device configures the corresponding P v , β for {4, 4, 4}. However, since the terminal can select 2 or 1 of the 3 TRPs to provide services for the terminal, the network device needs to additionally configure the corresponding P v , β for the SD basis combination {4, 4} or {4}, which has not been determined.

[0078] Therefore, the present disclosure provides a communication parameter determination method, apparatus, device, and storage medium. By receiving first information, a first number of first beam combination and at least one first parameter combination corresponding thereto are determined. The terminal performs CSI reporting based on the determined first beam combination and the corresponding first parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0079] FIG. 2 is a flow chart of a communication parameter determination method according to an exemplary embodiment. As shown in FIG. 2, the method is performed by a terminal and can include the following steps:

[0080] In step S11, first information is received.

[0081] In some embodiments, the terminal can receive the first information.

[0082] For example, the terminal can receive the first information sent by the network device, and the first information can indicate a first number of first beam combinations. For example, the first information indicates a first number of SD basis combinations.

[0083] For another example, the terminal receives the first information sent by the network device, and the first information can indicate at least one first parameter combination corresponding to the first number of beam combinations. The first parameter combination can include P v and β.

[0084] For another example, the terminal receives the first information sent by the network device, and the first information can indicate a first number of first beam combinations, and the first information can also indicate at least one first parameter combination corresponding to the first number of beam combinations.

[0085] For example, in the case of TRP being 2, if the first number is 1, the first beam array combination of the first number can be {2, 2}, {2, 4}, {4, 2} or {4, 4}. If the first number is 2, the first beam array combination of the first number can be any two of {2, 2}, {2, 4}, {4, 2} and {4, 4}. If the first number is 4, the first beam array combination of the first number can be {2, 2}, {2, 4}, {4, 2} and {4, 4}. It can be understood that one or more numbers in each beam array combination are used to represent one or more beam numbers in the beam array combination. Each beam number can be understood as the number of beams that need to be selected for the corresponding CSI-RS resource (or TRP).

[0086] It can be understood that P v The larger the is, the more frequency domain basis vectors that need to be selected. The larger the is, the more non-zero coefficients.

[0087] In step S12, a first beam array combination of a first number is determined based on the first information, and at least one first parameter combination corresponding to the first beam array combination of the first number is determined.

[0088] In some embodiments, the terminal can determine the first beam array combination of the first number and the at least one first parameter combination corresponding to the first beam array combination of the first number according to the first information received in S12.

[0089] For example, the first information can include a parameter indicating the first beam array combination of the first number. The terminal can determine the first beam array combination of the first number based on the parameter.

[0090] For another example, the first information can include a parameter indicating the at least one first parameter combination corresponding to the first beam array combination of the first number. The terminal can determine the at least one first parameter combination corresponding to the first beam array combination of the first number based on the parameter.

[0091] For another example, the first information can include a parameter indicating the first beam array combination of the first number, and a parameter indicating the at least one first parameter combination corresponding to the first beam array combination of the first number. The terminal can determine the first beam array combination of the first number and the at least one first parameter combination corresponding to the first beam array combination of the first number based on the above parameters.

[0092] It can be understood that the present disclosure determines the first beam array combination and the at least one first parameter combination corresponding thereto through the first information, avoiding the terminal from being unclear about which P vand β. Thus, the at least one first parameter combination corresponding to the one or more first beam combination can be avoided to be configured between the network device and the terminal through additional signaling. In turn, the additional signaling overhead is reduced.

[0093] The present disclosure receives the first information to determine the first quantity of first beam combinations and the at least one first parameter combination corresponding thereto, so that the terminal reports the CSI based on the determined first beam combinations and the first parameter combinations corresponding thereto, thereby reducing the signaling overhead and improving the CJT performance.

[0094] The communication parameter determination method provided by the embodiments of the present disclosure, the first information includes a first link identifier, the first link identifier has a first correspondence relationship with the first beam combination and / or the first parameter combination. The first correspondence relationship includes at least one of the following: the first link identifier corresponds to one first beam combination; the first link identifier corresponds to multiple first beam combinations; and the first link identifier corresponds to one first parameter combination.

[0095] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with the first beam combination.

[0096] For example, the first information received by the terminal includes a first link identifier, and the first link identifier has a first correspondence relationship with the first beam combination. The terminal can determine the first beam combination according to the first link identifier. For example, the terminal determines the first quantity of first beam combinations.

[0097] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with the first parameter combination.

[0098] For example, the first information received by the terminal includes a first link identifier, and the first link identifier has a first correspondence relationship with the first parameter combination. The terminal can determine the first parameter combination according to the first link identifier. For example, the terminal determines the at least one first parameter combination corresponding to the first quantity of first beam combinations.

[0099] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with the first beam combination and the first parameter combination.

[0100] For example, the first information received by the terminal includes a first link identifier, and the first link identifier has a first correspondence relationship with the first beam combination and the first parameter combination. The terminal can determine the first beam combination and the first parameter combination according to the first link identifier. For example, the terminal determines the first quantity of first beam combinations and the at least one first parameter combination corresponding to the first quantity of first beam combinations.

[0101] In some embodiments, the first correspondence comprises that a first link identifier corresponds to one first beam combination.

[0102] For example, the first link identifier 1 corresponds to the first beam combination 1: {2, 2, 2}, and the first link identifier 2 corresponds to the first beam combination 2: {4, 4, 4}. Then, if the first information contains the first link identifier 1, the terminal can determine the first beam combination 1: {2, 2, 2}; or, if the first information contains the first link identifier 2, the terminal can determine the first beam combination 2: {4, 4, 4}.

[0103] In some embodiments, the first correspondence comprises that a first link identifier corresponds to a plurality of first beam combinations.

[0104] For example, the first link identifier 1 corresponds to the first beam combination 1: {2, 2, 2} and the first beam combination 2: {4, 4, 4}. Then, if the first information contains the first link identifier 1, the terminal can determine the first beam combination 1: {2, 2, 2} and the first beam combination 2: {4, 4, 4}.

[0105] In some embodiments, the first correspondence comprises that a first link identifier corresponds to one first parameter combination.

[0106] For example, the first link identifier 1 corresponds to the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}, and the first link identifier 2 corresponds to the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can determine the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can determine the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0107] In some embodiments, the first correspondence comprises that a first link identifier corresponds to one first beam combination, and the first link identifier corresponds to one first parameter combination. That is, each first beam combination corresponds to one first parameter combination.

[0108] For example, the first link identifier 1 corresponds to the first beam combination 1 : {2, 2, 2} and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}, and the first link identifier 2 corresponds to the first beam combination 2: {4, 4, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can determine the first beam combination 1 : {2, 2, 2} and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can determine the first beam combination 2: {4, 4, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0109] In some embodiments, the first correspondence relationship includes that the first link identifier corresponds to a plurality of first beam combinations, and the first link identifier corresponds to one first parameter combination. That is, the plurality of first beam combinations correspond to one first parameter combination.

[0110] For example, the first link identifier 1 corresponds to the first beam combination 1 : {2, 2, 2}, the first beam combination 2: {4, 4, 4} and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; the first link identifier 2 corresponds to the first beam combination 3: {2, 4, 2}, the first beam combination 4: {2, 2, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can determine the first beam combination 1 : {2, 2, 2}, the first beam combination 2: {4, 4, 4} and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can determine the first beam combination 3: {2, 4, 2}, the first beam combination 4: {2, 2, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0111] It can be understood that the first beam combination and the first parameter combination can be corresponded by the link identifier. In this case, the first information only needs to carry the first link identifier, and the terminal can determine the first beam combination and the first parameter combination according to the first link identifier.

[0112] In some embodiments, the identifier can be an identity (ID) or an index.

[0113] The disclosure determines a first quantity of first beam array combinations and corresponding at least one first parameter combination through linkage identification. The terminal reports CSI based on the determined first beam array combination and corresponding first parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0114] The communication parameter determination method provided in the embodiments of the disclosure includes first information. The first information includes a first beam array combination identifier and a first parameter combination identifier.

[0115] In some embodiments, the first information can include a first beam array combination identifier and a first parameter combination identifier.

[0116] For example, the first information includes at least one first beam array combination identifier and at least one first parameter combination identifier. The first parameter combination indicated by the first parameter combination identifier corresponds to the first beam array combination indicated by the first beam array combination identifier.

[0117] The terminal can determine the first beam array combination based on the first beam array combination identifier, and determine the first parameter combination based on the first parameter combination identifier.

[0118] In this case, it can be unnecessary to establish linkage for the first beam array combination and the first parameter combination. The terminal can determine the first beam array combination through the first beam array combination identifier, and determine the first parameter combination through the first parameter combination identifier.

[0119] For example, the first information can include one first beam array combination identifier and one first parameter combination identifier. The terminal can determine the first beam array combination indicated by the one first beam array combination identifier based on the one first beam array combination identifier included in the first information; and the terminal can determine the first parameter combination indicated by the one first parameter combination identifier based on the one first parameter combination identifier included in the first information.

[0120] For another example, the first information can include multiple first beam array combination identifiers and one first parameter combination identifier. For example, the first information can include a first beam array combination identifier 1, a first beam array combination identifier 2, and a first parameter combination identifier 1. The terminal can determine a first beam array combination 1 based on the first beam array combination identifier 1 included in the first information; the terminal can determine a first beam array combination 2 based on the first beam array combination identifier 2 included in the first information; and the terminal can determine a first parameter combination 1 based on the first parameter combination identifier 1 included in the first information. The first beam array combination 1 corresponds to the first parameter combination 1, and the first beam array combination 2 corresponds to the first parameter combination 1.

[0121] For another example, the first information can comprise a plurality of first beam combination identification and a plurality of first parameter combination identification. For example, the first information can comprise first beam combination identification 1, first beam combination identification 2, first parameter combination identification 1 and first parameter combination identification 2. The terminal can determine the first beam combination 1 based on the first beam combination identification 1 comprised in the first information; and the terminal can determine the first beam combination 2 based on the first beam combination identification 2 comprised in the first information; and the terminal can determine the first parameter combination 1 based on the first parameter combination identification 1 comprised in the first information; and the terminal can determine the first parameter combination 2 based on the first parameter combination identification 2 comprised in the first information. Wherein, the first beam combination 1 corresponds to the first parameter combination 1, and the first beam combination 2 corresponds to the first parameter combination 2.

[0122] The present disclosure determines the first number of first beam combinations and the corresponding at least one first parameter combination through the first beam combination identification and the first parameter combination identification respectively. The terminal reports the CSI based on the determined first beam combination and the corresponding first parameter combination, thereby reducing the signaling overhead and improving the CJT performance.

[0123] In the communication parameter determination method provided by the embodiments of the present disclosure, the first number of values comprises at least one of the following: 1; 2; 4.

[0124] In some embodiments, the first number can be 1.

[0125] For example, the terminal determines one first SD basis combination based on the first information.

[0126] In some embodiments, the first number can be 2.

[0127] For example, the terminal determines two first SD basis combinations based on the first information.

[0128] In some embodiments, the first number can be 4.

[0129] For example, the terminal determines four first SD basis combinations based on the first information.

[0130] It can be understood that the first number can be the number of SD basis combinations that the terminal can support to maintain simultaneously.

[0131] The present disclosure provides a plurality of possible cases of the first number. In order to determine the first number of first beam combinations and the corresponding at least one first parameter combination by receiving the first information. The terminal reports the CSI based on the determined first beam combination and the corresponding first parameter combination, thereby reducing the signaling overhead and improving the CJT performance.

[0132] The communication parameter determination method provided in the embodiments of the present disclosure can further include the following steps.

[0133] In step S21, a second number of second beam array combinations and at least one second parameter combination corresponding to the second number of second beam array combinations are determined.

[0134] In some embodiments, the terminal can determine a second number of second beam array combinations and at least one second parameter combination corresponding to the second number of second beam array combinations. The second beam array combination is a subset of the first beam array combination. The second parameter combination includes P v and β.

[0135] For example, the terminal can determine a second number of second beam array combinations. The second beam array combination can be a subset of the first beam array combination. For example, the first beam array combination is {2, 4, 2}. The second beam array combination can be {4, 2}, {2, 4}, {2, 2}, {4} and / or {2}.

[0136] For another example, the terminal can determine at least one second parameter combination corresponding to the second number of second beam array combinations. For example, a plurality of second beam array combinations can correspond to P v and β, respectively; or, a plurality of second beam array combinations can correspond to one P v and β, that is, the P v and β corresponding to the plurality of second beam array combinations are the same.

[0137] It can be understood that the first beam array combination can be a beam array combination corresponding to N TRPs, and the second beam array combination can be a beam array combination corresponding to the selected TRPs after the terminal selects part or all of the N TRPs. In other words, the number of beams in the first beam array combination is N, and N represents the number of non-zero power (NZP) CSI-RS resources included in a CMR configured by the network device, which can also be understood as the number of TRPs. The number of beams in the second beam array combination can be M, and M is less than or equal to N.

[0138] For example, in the case of N=3, the network device can configure the first beam array combination {2, 4, 2} through the first information, as shown in Table 1. The network device can also configure the P vAnd β. For the terminal, 2 or 1 of the 3 TRPs can be selected to provide services for the terminal. In this case, the second beam array combination can be {4, 2}, {2, 4}, {2, 2}, {4} and / or {2}. It can be seen that the first beam array combination can correspond to multiple second beam array combinations.

[0139] In some embodiments, the terminal determines the second quantity of second beam array combinations and the at least one second parameter combination corresponding to the second quantity of second beam array combinations based on information sent by the network device for configuring the second quantity of second beam array combinations and the at least one second parameter combination corresponding to the second quantity of second beam array combinations, or based on the first quantity of first beam array combinations and the at least one first parameter combination corresponding to the first quantity of first beam array combinations, which is not limited by the present disclosure.

[0140] For example, the terminal receives information for configuring the second quantity of second beam array combinations and the at least one second parameter combination corresponding to the second quantity of second beam array combinations. The terminal determines the second quantity of second beam array combinations and the at least one second parameter combination corresponding to the second quantity of second beam array combinations based on the information.

[0141] For another example, the terminal determines the second quantity of second beam array combinations based on the TRP selected by itself and based on the first quantity of first beam array combinations. The terminal can also determine the at least one second parameter combination corresponding to the second beam array combination based on the at least one first parameter combination corresponding to the first beam combination.

[0142] Of course, in some cases, the terminal can determine the second quantity of second beam array combinations based on the TRP selected by itself and based on the first quantity of first beam array combinations. And receive information for configuring the at least one second parameter combination corresponding to the second quantity of second beam array combinations. And determine the at least one second parameter combination corresponding to the second quantity of second beam array combinations based on the information.

[0143] The present disclosure can determine the second beam array combination belonging to the subset of the first beam array combination and the at least one second parameter combination corresponding thereto. So that the terminal reports CSI based on the determined second beam array combination and the second parameter combination corresponding thereto, thereby reducing signaling overhead and improving CJT performance.

[0144] The communication parameter determination method provided by the embodiments of the present disclosure can further include the following steps:

[0145] In step S31, the second information is received.

[0146] In some embodiments, the terminal can receive the second information.

[0147] For example, the terminal receives the second information sent by the network device. The second information can be used to configure at least one second parameter combination corresponding to the second number of second beam array combinations.

[0148] The second information can be referred to as second configuration information, second indication information, second parameter combination configuration information, etc., and the disclosure does not limit the name of the second information.

[0149] In some embodiments, the second information and the first information can be the same information or different information.

[0150] For example, the second information and the first information are included in the same RRC signaling. For another example, the second information and the first information are included in different RRC signaling respectively.

[0151] In step S32, at least one second parameter combination corresponding to the second number of second beam array combinations is determined based on the second information.

[0152] In some embodiments, based on the second information received in S31, the terminal can determine at least one second parameter combination corresponding to the second number of second beam array combinations.

[0153] For example, the terminal receives the second information, which includes parameters for indicating at least one second parameter combination corresponding to the second number of second beam array combinations. The terminal determines at least one second parameter combination corresponding to the second number of second beam array combinations based on the parameters.

[0154] The disclosure determines at least one second parameter combination corresponding to the second number of second beam array combinations. The terminal reports CSI based on the determined second beam array combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0155] In the communication parameter determination method provided by the embodiments of the disclosure, the second information includes a second link identifier, the second link identifier has a second correspondence relationship with the second beam array combination and / or the second parameter combination; and the second correspondence relationship includes at least one of the following: the second link identifier corresponds to one second beam array combination; the second link identifier corresponds to a plurality of second beam array combinations; and the second link identifier corresponds to one second parameter combination.

[0156] In some embodiments, the second information can include a second link identifier. The second link identifier has a second correspondence relationship with the second beam array combination.

[0157] For example, the second information received by the terminal comprises a second link identifier, and the second link identifier has a second correspondence relationship with the second beam combination. The terminal can determine the second beam combination according to the second link identifier. For example, the terminal determines the second quantity of second beam combinations.

[0158] In some embodiments, the second information can comprise a second link identifier. The second link identifier has a second correspondence relationship with the second parameter combination.

[0159] For example, the second information received by the terminal comprises a second link identifier, and the second link identifier has a second correspondence relationship with the second parameter combination. The terminal can determine the second parameter combination according to the second link identifier. For example, the terminal determines the second quantity of second beam combinations corresponding to at least one second parameter combination.

[0160] In some embodiments, the second information can comprise a second link identifier. The second link identifier has a second correspondence relationship with the second beam combination and the second parameter combination.

[0161] For example, the second information received by the terminal comprises a second link identifier, and the second link identifier has a second correspondence relationship with the second beam combination and the second parameter combination. The terminal can determine the second beam combination and the second parameter combination according to the second link identifier. For example, the terminal determines the second quantity of second beam combinations and at least one second parameter combination corresponding to the second quantity of second beam combinations.

[0162] In some embodiments, the second correspondence relationship comprises that one second link identifier corresponds to one second beam combination.

[0163] For example, the second link identifier 1 corresponds to the second beam combination 1: {2, 2}, and the second link identifier 2 corresponds to the second beam combination 2: {2, 4}. If the second information contains the second link identifier 1, the terminal can determine the second beam combination 1: {2, 2}. If the second information contains the second link identifier 2, the terminal can determine the second beam combination 2: {2, 4}.

[0164] In some embodiments, the second correspondence relationship comprises that one second link identifier corresponds to multiple second beam combinations.

[0165] For example, the second link identifier 1 corresponds to the second beam combination 1: {2, 2} and the second beam combination 2: {2, 4}. If the second information contains the second link identifier 1, the terminal can determine the second beam combination 1: {2, 2} and the second beam combination 2: {2, 4}.

[0166] In some embodiments, the second correspondence relationship comprises that one second link identifier corresponds to one second parameter combination.

[0167] For example, the second link identifier 1 corresponds to the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2} and the second link identifier 2 corresponds to the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identifier 1, the terminal can determine the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identifier 2, the terminal can determine the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0168] In some embodiments, the second correspondence relationship includes that the second link identifier corresponds to a second beam combination and the second link identifier corresponds to a second parameter combination. That is, each second beam combination corresponds to a second parameter combination.

[0169] For example, the second link identifier 1 corresponds to the second beam combination 1: {2, 2} and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2} and the second link identifier 2 corresponds to the second beam combination 2: {2, 4} and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identifier 1, the terminal can determine the second beam combination 1: {2, 2} and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identifier 2, the terminal can determine the second beam combination 2: {2, 4} and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0170] In some embodiments, the second correspondence relationship includes that the second link identifier corresponds to a plurality of second beam combinations and the second link identifier corresponds to a second parameter combination. That is, the plurality of second beam combinations corresponds to a second parameter combination.

[0171] For example, the second link identity 1 corresponds to the second beam combination 1: {2, 2}, the second beam combination 2: {2, 4}, and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; the second link identity 2 corresponds to the second beam combination 3: {2}, the second beam combination 4: {4}, and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identity 1, the terminal can determine the second beam combination 1: {2, 2}, the second beam combination 2: {2, 4}, and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identity 2, the terminal can determine the second beam combination 3: {2}, the second beam combination 4: {4}, and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0172] It can be understood that the second beam combination and the second parameter combination can establish a corresponding relationship through the link identity. In this case, the second information only needs to carry the second link identity, and the terminal can determine the second beam combination and the second parameter combination according to the second link identity.

[0173] In some embodiments, the identifier can be an ID or an index.

[0174] The present disclosure determines a second number of second beam combinations and at least one second parameter combination corresponding thereto through a link identity. The terminal reports CSI based on the determined second beam combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0175] In the communication parameter determination method provided by the embodiments of the present disclosure, the second information includes a second beam combination identifier and a second parameter combination identifier; or the second information includes a second parameter combination identifier.

[0176] In some embodiments, the second information can include a second parameter combination identifier.

[0177] For example, the terminal can determine a second parameter combination according to the second parameter combination identifier in the second information. For example, determine one second parameter combination. In this case, it can be considered that the one second parameter combination determined by the terminal is used for one or more second beam combinations. That is, it can be considered that the one or more second beam combinations determined by the terminal correspond to the same one second parameter combination, that is, the second parameter combination indicated by the second parameter combination identifier.

[0178] In some embodiments, the second information can include a second beam combination identifier and a second parameter combination identifier.

[0179] For example, the second information includes at least one second beam array combination identifier, and at least one second parameter combination identifier. The second parameter combination indicated by the second parameter combination identifier corresponds to the second beam array combination indicated by the second beam array combination identifier.

[0180] The terminal can determine the second beam array combination based on the second beam array combination identifier, and determine the second parameter combination based on the second parameter combination identifier.

[0181] In this case, the second beam array combination and the second parameter combination can be linked without establishing a link. The terminal can determine the second beam array combination through the second beam array combination identifier, and determine the second parameter combination through the second parameter combination identifier.

[0182] The present disclosure determines a second number of second beam array combinations and at least one second parameter combination corresponding thereto through the second beam array combination identifier and the second parameter combination identifier, respectively. The terminal reports CSI based on the determined second beam array combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0183] The communication parameter determination method provided in the embodiments of the present disclosure can be used to determine the second parameter combination to be the same as the first parameter combination.

[0184] In some embodiments, the second parameter combination corresponding to the second beam array combination can be the same as the first parameter combination corresponding to the first beam array combination.

[0185] For example, the P v and β corresponding to the second beam array combination are the same as the P v and β corresponding to the first beam array combination. In other words, the terminal can use the P v and β corresponding to the first beam array combination as the P v and β corresponding to the second beam array combination.

[0186] The present disclosure provides a determination method of the second parameter combination, so that the terminal reports CSI based on the determined second beam array combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0187] Based on the same concept, the present disclosure also provides a communication parameter determination method performed by a network device.

[0188] FIG. 5 is a flowchart of another communication parameter determination method according to an exemplary embodiment. As shown in FIG. 5, the method performed by the network device can include the following steps:

[0189] In step S41, the first information is transmitted.

[0190] In some embodiments, the network device can send the first information.

[0191] For example, the network device can send the first information to the terminal, and the first information can indicate the first quantity of first beam array combinations. As the first information indicates the first quantity of SD basis array combinations.

[0192] For another example, the network device can send the first information to the terminal, and the first information can indicate at least one first parameter combination corresponding to the first quantity of beam array combinations. Wherein, the first parameter combination can include P v and β.

[0193] For another example, the network device can send the first information to the terminal, and the first information can indicate the first quantity of first beam array combinations, and the first information can also indicate at least one first parameter combination corresponding to the first quantity of beam array combinations.

[0194] For example, in the case of TRP being 2, if the first quantity is 1, the first quantity of first beam array combinations can be {2, 2}, {2, 4}, {4, 2} or {4, 4}. If the first quantity is 2, the first quantity of first beam array combinations can be any two of {2, 2}, {2, 4}, {4, 2} and {4, 4}. If the first quantity is 4, the first quantity of first beam array combinations can be {2, 2}, {2, 4}, {4, 2} and {4, 4}. It can be understood that one or more numbers in each beam array combination are used to represent one or more beam numbers in the beam array combination. Each beam number can be understood as the number of beams that need to be selected corresponding to the CSI-RS resource (or TRP).

[0195] It can be understood that P v The larger P

[0196] It can be understood that the present disclosure determines the first beam array combination and its corresponding at least one first parameter combination through the first information, which avoids the terminal from being unclear about which P v and β to use in determining the first beam array combination. Thus, it can be avoided that the network device and the terminal configure at least one first parameter combination corresponding to one or more first beam array combinations through additional signaling. Further, the additional signaling overhead is reduced.

[0197] The present disclosure determines the first quantity of first beam array combinations and its corresponding at least one first parameter combination by receiving the first information. This makes the terminal perform CSI reporting based on the determined first beam array combination and its corresponding first parameter combination, thereby reducing the signaling overhead and improving the CJT performance.

[0198] In the method for determining a communication parameter provided by the embodiments of the present disclosure, the first information includes a first link identifier, and the first link identifier has a first correspondence relationship with a first beam array combination and / or a first parameter combination. The first correspondence relationship includes at least one of the following: the first link identifier corresponds to one first beam array combination; the first link identifier corresponds to a plurality of first beam array combinations; and the first link identifier corresponds to one first parameter combination.

[0199] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with a first beam array combination.

[0200] For example, the first information sent by the network device includes a first link identifier, and the first link identifier has a first correspondence relationship with a first beam array combination.

[0201] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with a first parameter combination.

[0202] For example, the first information sent by the network device includes a first link identifier, and the first link identifier has a first correspondence relationship with a first parameter combination.

[0203] In some embodiments, the first information can include a first link identifier. The first link identifier has a first correspondence relationship with a first beam array combination and a first parameter combination.

[0204] For example, the first information sent by the network device includes a first link identifier, and the first link identifier has a first correspondence relationship with a first beam array combination and a first parameter combination.

[0205] In some embodiments, the first correspondence relationship includes that the first link identifier corresponds to one first beam array combination.

[0206] For example, the first link identifier 1 corresponds to the first beam combination 1: {2, 2, 2}, and the first link identifier 2 corresponds to the first beam combination 2: {4, 4, 4}. If the first information includes the first link identifier 1, the terminal can determine the first beam combination 1: {2, 2, 2}; or if the first information includes the first link identifier 2, the terminal can determine the first beam combination 2: {4, 4, 4}.

[0207] In some embodiments, the first correspondence relationship includes that the first link identifier corresponds to a plurality of first beam array combinations.

[0208] For example, the first link identifier 1 corresponds to the first beam combination 1: {2, 2, 2} and the first beam combination 2: {4, 4, 4}. Then, if the first information contains the first link identifier 1, the terminal can be caused to determine the first beam combination 1: {2, 2, 2} and the first beam combination 2: {4, 4, 4}.

[0209] In some embodiments, the first correspondence relationship includes that a first link identifier corresponds to a first parameter combination.

[0210] For example, the first link identifier 1 corresponds to the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2} and the first link identifier 2 corresponds to the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can be caused to determine the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can be caused to determine the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0211] In some embodiments, the first correspondence relationship includes that a first link identifier corresponds to a first beam combination and the first link identifier corresponds to a first parameter combination. That is, each first beam combination corresponds to a first parameter combination.

[0212] For example, the first link identifier 1 corresponds to the first beam combination 1: {2, 2, 2} and the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2} and the first link identifier 2 corresponds to the first beam combination 2: {4, 4, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can be caused to determine the first beam combination 1: {2, 2, 2} and the first parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can be caused to determine the first beam combination 2: {4, 4, 4} and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0213] In some embodiments, the first correspondence relationship includes that a first link identifier corresponds to a plurality of first beam combinations and the first link identifier corresponds to a first parameter combination. That is, the plurality of first beam combinations correspond to a first parameter combination.

[0214] For example, the first link identifier 1 corresponds to the first beam combination 1 : {2, 2, 2}, the first beam combination 2: {4, 4, 4}, and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; the first link identifier 2 corresponds to the first beam combination 3: {2, 4, 2}, the first beam combination 4: {2, 2, 4}, and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the first information contains the first link identifier 1, the terminal can be caused to determine the first beam combination 1 : {2, 2, 2}, the first beam combination 2: {4, 4, 4}, and the first parameter combination 1 : {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the first information contains the first link identifier 2, the terminal can be caused to determine the first beam combination 3: {2, 4, 2}, the first beam combination 4: {2, 2, 4}, and the first parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0215] It can be understood that the first beam combination and the first parameter combination can establish a corresponding relationship through the link identifier. In this case, the first information only needs to carry the first link identifier, so that the terminal determines the first beam combination and the first parameter combination according to the first link identifier.

[0216] In some embodiments, the identifier can be an ID or an index.

[0217] The present disclosure determines a first number of first beam combinations and at least one first parameter combination corresponding thereto through a link identifier. The terminal reports CSI based on the determined first beam combination and the first parameter combination corresponding thereto, thereby reducing signaling overhead and improving CJT performance.

[0218] In the communication parameter determination method provided by the embodiments of the present disclosure, the first information includes a first beam combination identifier and a first parameter combination identifier.

[0219] In some embodiments, the first information can include a first beam combination identifier and a first parameter combination identifier.

[0220] For example, the first information includes at least one first beam combination identifier and at least one first parameter combination identifier. The first parameter combination indicated by the first parameter combination identifier corresponds to the first beam combination indicated by the first beam combination identifier.

[0221] In this case, it can be unnecessary to establish a link for the first beam combination and the first parameter combination. The terminal can determine the first beam combination through the first beam combination identifier and determine the first parameter combination through the first parameter combination identifier.

[0222] For example, the first information can include one first beam combination identifier and one first parameter combination identifier. So that the terminal can determine the first beam combination indicated by the one first beam combination identifier included in the first information based on the one first beam combination identifier; and so that the terminal can determine the first parameter combination indicated by the one first parameter combination identifier included in the first information based on the one first parameter combination identifier.

[0223] For another example, the first information can include multiple first beam combination identifiers and one first parameter combination identifier. For example, the first information can include first beam combination identifier 1, first beam combination identifier 2 and first parameter combination identifier 1. So that the terminal can determine first beam combination 1 based on the first beam combination identifier 1 included in the first information; and so that the terminal can determine first beam combination 2 based on the first beam combination identifier 2 included in the first information; and so that the terminal can determine the first parameter combination 1 based on the first parameter combination identifier 1 included in the first information. Wherein the first beam combination 1 corresponds to the first parameter combination 1, and the first beam combination 2 corresponds to the first parameter combination 1.

[0224] For another example, the first information can include multiple first beam combination identifiers and one first parameter combination identifier. For example, the first information can include first beam combination identifier 1, first beam combination identifier 2, first parameter combination identifier 1 and first parameter combination identifier 2. So that the terminal can determine first beam combination 1 based on the first beam combination identifier 1 included in the first information; and so that the terminal can determine first beam combination 2 based on the first beam combination identifier 2 included in the first information; and so that the terminal can determine the first parameter combination 1 based on the first parameter combination identifier 1 included in the first information; and so that the terminal can determine the first parameter combination 2 based on the first parameter combination identifier 2 included in the first information. Wherein the first beam combination 1 corresponds to the first parameter combination 1, and the first beam combination 2 corresponds to the first parameter combination 2.

[0225] The present disclosure determines a first number of first beam combinations and at least one corresponding first parameter combination through a first beam combination identifier and a first parameter combination identifier respectively. So that the terminal reports CSI based on the determined first beam combination and the corresponding first parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0226] In the communication parameter determination method provided by the embodiments of the present disclosure, the first number of values includes at least one of the following: 1; 2; 4.

[0227] In some embodiments, the first number can be 1.

[0228] For example, the network device indicates one first SD basis combination through the first information.

[0229] In some embodiments, the first number can be 2.

[0230] For example, the network device indicates two first SD basis combinations through the first information.

[0231] In some embodiments, the first number can be 4.

[0232] For example, the network device indicates four first SD basis combinations through the first information.

[0233] It can be understood that the first number can be the number of SD basis combinations that the terminal can support to maintain simultaneously.

[0234] The present disclosure provides a plurality of possible cases of the first number. In order to determine the first number of first beam combinations and their corresponding at least one first parameter combination by receiving the first information. So that the terminal reports CSI based on the determined first beam combination and its corresponding first parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0235] The communication parameter determination method provided by the embodiments of the present disclosure, Fig. 6 is another communication parameter determination method flow chart according to an exemplary embodiment. As shown in Fig. 6, the method can also include the following steps:

[0236] In step S51, the second information is sent.

[0237] In some embodiments, the network device can send the second information.

[0238] For example, the network device sends the second information to the terminal. The second information can be used to configure at least one second parameter combination corresponding to the second number of second beam combinations. Wherein the second beam combination is a subset of the first beam combination. The second parameter combination includes P v And β.

[0239] For example, the second beam array combination can be a subset of the first beam array combination. It can be understood that the first beam array combination can be a beam array combination corresponding to N TRPs, and the second beam array combination can be a beam array combination corresponding to the selected TRPs after the terminal selects part or all of the N TRPs. Wherein, there can be part of the TRPs not selected by the terminal. That is, the number of beams in the first beam array combination is N, and N represents the number of NZP CSI-RS resources included in a CMR configured by the network device, which can also be understood as the number of TRPs. The number of beams in the second beam array combination can be M. Wherein, M is less than or equal to N.

[0240] For example, when N is 3, the first beam array combination that the network device can configure through the first information can be {2, 4, 2} as shown in Table 1. The network device can also configure the P v And β. For the terminal, 2 or 1 of the 3 TRPs can be selected to provide services for the terminal. In this case, the second beam array combination can be {4, 2}, {2, 4}, {2, 2}, {4}, and / or {2}. It can be seen that the first beam array combination can correspond to multiple second beam array combinations.

[0241] In some embodiments, the second information can be referred to as second configuration information, second indication information, second parameter combination configuration information, etc., and the name of the second information is not limited in the present disclosure.

[0242] In some embodiments, the second information and the first information can be the same information or different information.

[0243] For example, the second information and the first information are included in the same RRC signaling. For example, the second information and the first information are included in different RRC signaling.

[0244] The present disclosure determines at least one second parameter combination corresponding to the second number of second beam array combinations, so that the terminal reports CSI based on the determined second beam array combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0245] In the communication parameter determination method provided by the embodiments of the present disclosure, the second information includes a second link identifier, and the second link identifier has a second correspondence relationship with the second beam array combination and / or the second parameter combination; wherein the second correspondence relationship includes at least one of the following: the second link identifier corresponds to one second beam array combination; the second link identifier corresponds to multiple second beam array combinations; and the second link identifier corresponds to one second parameter combination.

[0246] In some embodiments, the second information can comprise a second link identifier. Wherein the second link identifier has a second correspondence with the second parameter combination.

[0247] For example, the second information sent by the network device comprises a second link identifier, which has a second correspondence with the second parameter combination.

[0248] In some embodiments, the second information can comprise a second link identifier. Wherein the second link identifier has a second correspondence with the second parameter combination.

[0249] For example, the second information sent by the network device comprises a second link identifier, which has a second correspondence with the second parameter combination.

[0250] In some embodiments, the second information can comprise a second link identifier. Wherein the second link identifier has a second correspondence with the second parameter combination.

[0251] For example, the second information sent by the network device comprises a second link identifier, which has a second correspondence with the second parameter combination.

[0252] In some embodiments, the second correspondence comprises that the second link identifier corresponds to one second parameter combination.

[0253] For example, the second link identifier 1 corresponds to the second parameter combination 1: {2, 2}, and the second link identifier 2 corresponds to the second parameter combination 2: {2, 4}. If the second information contains the second link identifier 1, the terminal can determine the second parameter combination 1: {2, 2}; or if the second information contains the second link identifier 2, the terminal can determine the second parameter combination 2: {2, 4}.

[0254] In some embodiments, the second correspondence comprises that the second link identifier corresponds to multiple second parameter combinations.

[0255] For example, the second link identifier 1 corresponds to the second parameter combination 1: {2, 2} and the second parameter combination 2: {2, 4}. If the second information contains the second link identifier 1, the terminal can determine the second parameter combination 1: {2, 2} and the second parameter combination 2: {2, 4}.

[0256] In some embodiments, the second correspondence comprises that the second link identifier corresponds to one second parameter combination.

[0257] For example, the second link identifier 1 corresponds to the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}, and the second link identifier 2 corresponds to the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identifier 1, the terminal can be caused to determine the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identifier 2, the terminal can be caused to determine the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0258] In some embodiments, the second correspondence relationship includes that the second link identifier corresponds to a second beam combination, and the second link identifier corresponds to a second parameter combination. That is, each second beam combination corresponds to a second parameter combination.

[0259] For example, the second link identifier 1 corresponds to the second beam combination 1: {2, 2} and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}, and the second link identifier 2 corresponds to the second beam combination 2: {2, 4} and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identifier 1, the terminal can be caused to determine the second beam combination 1: {2, 2} and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identifier 2, the terminal can be caused to determine the second beam combination 2: {2, 4} and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0260] In some embodiments, the second correspondence relationship includes that the second link identifier corresponds to a plurality of second beam combinations, and the second link identifier corresponds to a second parameter combination. That is, the plurality of second beam combinations correspond to a second parameter combination.

[0261] For example, the second link identity 1 corresponds to the second beam combination 1: {2, 2}, the second beam combination 2: {2, 4}, and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; the second link identity 2 corresponds to the second beam combination 3: {2}, the second beam combination 4: {4}, and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}. Then, if the second information contains the second link identity 1, the terminal can be caused to determine the second beam combination 1: {2, 2}, the second beam combination 2: {2, 4}, and the second parameter combination 1: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 2}; or, if the second information contains the second link identity 2, the terminal can be caused to determine the second beam combination 3: {2}, the second beam combination 4: {4}, and the second parameter combination 2: {{1 / 4, 1 / 4, 1 / 8, 1 / 8}, 1 / 4}.

[0262] It can be understood that the second beam combination and the second parameter combination can establish a corresponding relationship through the link identity. In this case, the second information only needs to carry the second link identity, so that the terminal can determine the second beam combination and the second parameter combination according to the second link identity.

[0263] In some embodiments, the identifier can be an ID or an index.

[0264] The present disclosure determines a second number of second beam combinations and at least one second parameter combination corresponding thereto through a link identity. The terminal reports CSI based on the determined second beam combination and the corresponding second parameter combination, thereby reducing signaling overhead and improving CJT performance.

[0265] In the communication parameter determination method provided by the embodiments of the present disclosure, the second information includes a second beam combination identifier and a second parameter combination identifier; or the second information includes a second parameter combination identifier.

[0266] In some embodiments, the second information can include a second parameter combination identifier.

[0267] For example, the second parameter combination identifier in the second information can be used by the terminal to determine a second parameter combination. For example, to determine one second parameter combination. In this case, the one second parameter combination determined by the terminal can be considered to be used for one or more second beam combinations. That is, the one or more second beam combinations determined by the terminal can be considered to correspond to the same one second parameter combination, that is, the second parameter combination indicated by the second parameter combination identifier.

[0268] In some embodiments, the second information can include a second beam combination identifier and a second parameter combination identifier.

[0269] For example, the second information comprises at least one second beam array combination identifier and at least one second parameter combination identifier. The second parameter combination indicated by the second parameter combination identifier corresponds to the second beam array combination indicated by the second beam array combination identifier.

[0270] In this case, the second beam array combination and the second parameter combination can be linked without establishing a link. Thus, the terminal can determine the second beam array combination through the second beam array combination identifier and determine the second parameter combination through the second parameter combination identifier.

[0271] The disclosure determines a second number of second beam array combinations and at least one second parameter combination corresponding to the second beam array combinations through the second beam array combination identifier and the second parameter combination identifier, respectively. Thus, the terminal reports CSI based on the determined second beam array combination and the second parameter combination corresponding to the second beam array combination, thereby reducing signaling overhead and improving CJT performance.

[0272] The communication parameter determination method provided by the embodiments of the disclosure can be used to determine the second parameter combination to be the same as the first parameter combination.

[0273] In some embodiments, the second parameter combination corresponding to the second beam array combination can be the same as the first parameter combination corresponding to the first beam array combination.

[0274] For example, the P v and β corresponding to the second beam array combination are the same as the P v and β corresponding to the first beam array combination. In other words, the terminal can use the P v and β corresponding to the first beam array combination as the P v and β corresponding to the second beam array combination.

[0275] The disclosure provides a determination manner of the second parameter combination, so that the terminal reports CSI based on the determined second beam array combination and the second parameter combination corresponding to the second beam array combination, thereby reducing signaling overhead and improving CJT performance.
