Where the following description relates to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0046] The communication method relating to this disclosure can be applied to the wireless communication system 100 shown in Figure 1. This network system may include a network device 110 and a terminal 120. The wireless communication system shown in Figure 1 is for illustrative purposes only, and the wireless communication system may include other network devices not shown in Figure 1, such as a core network device, a wireless relay device, and a wireless backhaul device. The embodiments of this disclosure do not limit the number of network devices and terminals included in this wireless communication system.

[0047] Furthermore, the wireless communication system of the embodiments of this disclosure is a network that provides wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), broadband 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), and carrier-sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency of different networks, networks can be divided into future evolutionary networks such as 2G (2G generation) networks, 3G networks, 4G networks, or the 5th generation wireless communication system (5G) networks, and 5G networks can also be referred to as NR. For the sake of clarity, this disclosure may refer to wireless communication networks as simply "networks."

[0048] Furthermore, the network device 110 relating to this disclosure may also be referred to as a wireless access network device. This wireless access network device may be a base station, an evolved node B (eNB), a femtocell, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a TRP, or it may be a gNB in ​​an NR system, or it may be a component or part of a base station. In the case of a vehicle-to-vehicle (V2X) communication system, the network device may be an in-vehicle device. It should be understood that the embodiments of this disclosure are not limited to the specific technology or specific device form employed in the network device.

[0049] Furthermore, the terminal 120 relating to this disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device for providing voice and / or data communication to a user. For example, the terminal may be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include smartphones (mobile phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), notebook computers, tablet computers, wearable devices, or in-vehicle devices. Also, in the case of a vehicle-to-vehicle (V2X) communication system, the terminal device may be an in-vehicle device. It should be understood that the embodiments of this disclosure are not limited to the specific technologies and specific device forms employed in the terminal.

[0050] In the embodiments disclosed herein, a network device 110 and a terminal 120 can transmit data to each other using any viable wireless communication technology. The transmission path corresponding to when the network device 110 transmits data to the terminal 120 is referred to as the downlink channel (downlink, DL), and the transmission path corresponding to when the terminal 120 transmits data to the network device 110 is referred to as the uplink channel (uplink, UL). The network device in the embodiments disclosed herein may be a base station. Of course, the network device may be any other possible network device, and the terminal may be any possible terminal, and this disclosure is not limited thereto.

[0051] In some schemes, a network device can serve a terminal using four TRPs. In some schemes, a network device can be configured to include K CSI-RS resources in one channel measurement resource (CMR), meaning that the network device directs K TRPs, where K is a positive integer. At the same time, the network device also needs to set the number of beams to be selected for each CSI-RS resource (i.e., for each TRP). These beams can be referred to as space domain basis vectors (SD basis). That is, the network device's radio resource control (RRC) signaling sets up multiple beam combinations, and each beam combination includes the number of beams corresponding to each CSI-RS resource.

[0052] The beam in this disclosure can be replaced with an equivalent SD basis.

[0053] In some embodiments, terms such as "up", "uplink", "physical uplink" are interchangeable with each other, terms such as "downlink", "downlink link", "physical downlink link" are interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct connection link", "direct connection communication", "direct connection link communication" are interchangeable with each other.

[0054] In some embodiments, terms such as "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI" are interchangeable with each other.

[0055] The above SD basis is related to the number of ports of CSI-RS resources 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 may be, for example, the horizontal dimension, and the second dimension may be, for example, the vertical dimension.

[0056] Embodiments of the present disclosure provide the following combination methods for some beams, as shown in Table 1. JPEG2026513606000002.jpg137170 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.

[0057] Table 1 shows that a terminal can maintain one, two, or four beam combinations simultaneously. That is, the terminal needs to select one beam combination from the one, two, or four available and report it to the network device. Of course, in some embodiments, if there is only one beam combination, the terminal does not need to report it.

[0058] Each element in Table 1 exists independently, and these elements are listed exemplarily in the same table; however, it can be understood that not all elements in the table should exist simultaneously as shown in the table. The value of each of these elements does not depend on the value of any other element in Table 1. Therefore, a person skilled in the art will understand that the values ​​of each element in Table 1 are independent embodiments.

[0059] At the same time, the number of parameters of the frequency domain basis vector (FD basis) is P v It can be expressed as such, and non-zero coefficient parameters can be expressed as β. SD basis number combinations and P v For combinations of β, you can refer to the ones shown in Table 2. JPEG2026513606000003.jpg158170

[0060] "w / restriction" indicates that only rank 2 can be supported at most. "N / A" can be understood as not applicable. As can be seen from Table 2, the number of combinations of SD basis and P v All combinations of β are empty, indicating that there is no conclusion at this time. At the same time, P in Table 2 v There are four P's in the combination v This exists. That is, it indicates that the rank is at most 4. When the rank is 4, there are 4 layers, and each layer has 1 P v This corresponds to P in different layers. vThis is used to determine the number of frequency domain basis vectors to select in the corresponding layer. The number of frequency domain basis vectors to select is P = the total number of frequency domain basis vectors. v It can be determined by multiplying by .

[0061] Each element in Table 2 exists independently, and these elements are listed illustratively in the same table, but it is understood that not all elements in the table should exist simultaneously as shown in the table. The value of each of these elements does not depend on the value of any other element in Table 2. Therefore, a person skilled in the art will understand that the values ​​of each element in Table 2 are independent embodiments.

[0062] However, in some schemes, one parameter combination identifier is one SD basis number combination, one P v It can simultaneously handle one β. Therefore, the network device only needs to set one parameter combination identifier.

[0063] However, if the number of TRPs is constant, the number of SD basis combinations that a network device can configure may be one, two, or four. P corresponding to each combination v It is not determined whether β is set independently or all set to the same value. Assuming the TRP number is 3, the network device can set the SD basis number combination to, for example, {4,4,4}. The network device has a corresponding P for {4,4,4}. v β is set. However, the terminal can choose two or one of the three TRPs to provide service to the terminal. In this case, if the SD basis number combination is {4,4} or {4}, the network device will set the corresponding P v Similarly, no conclusion has been reached regarding whether or not it is necessary to add β.

[0064] Accordingly, this disclosure provides a method, apparatus, device, and storage medium for determining communication parameters. By receiving first information, a first number of first beam number combinations and at least one corresponding first parameter combination are determined. This allows a terminal to report a CSI based on the determined first beam number combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0065] Figure 2 is a flowchart illustrating a method for determining communication parameters, as shown in an exemplary example. As shown in Figure 2, the method is performed by a terminal and may include the following steps S11 to S12.

[0066] In step S11, the first piece of information is received.

[0067] In some embodiments, the terminal can receive the first information.

[0068] For example, a terminal can receive first information transmitted from a network device, and the first information can indicate a first beam number combination of a first number. For example, the first information indicates an SD basis number combination of a first number.

[0069] Furthermore, for example, a terminal receives first information transmitted from a network device, and the first information can indicate at least one first parameter combination corresponding to a first number of beam number combinations. The first parameter combination is P v It can include β.

[0070] Furthermore, for example, a terminal may receive first information transmitted from a network device, the first information may indicate a first number of first beam number combinations, and the first information may also indicate at least one first parameter combination corresponding to the first number of beam number combinations.

[0071] For example, if the TRP is 2 and the first number is 1, the first beam count combination for the first number may be {2,2}, {2,4}, {4,2}, or {4,4}. If the first number is 2, the first beam count combination for the first number may be any two of {2,2}, {2,4}, {4,2}, and {4,4}. If the first number is 4, the first beam count combination for the first number may be {2,2}, {2,4}, {4,2}, and {4,4}. Note that one or more digits in each beam count combination are used to represent one or more beam counts in that beam count combination. Each beam count can be understood as the number of beams to be selected for the corresponding CSI-RS resource (or TRP).

[0072] Note P v A larger value indicates a greater number of frequency-domain basis vectors to choose from. A larger value of β indicates a greater number of non-zero coefficients.

[0073] In step S12, a first number of first beam number combinations and at least one first parameter combination corresponding to the first number of first beam number combinations are determined based on the first information.

[0074] In some embodiments, the terminal can determine a first number of first beam number combinations and at least one first parameter combination corresponding to the first number of first beam number combinations based on the first information received in S12.

[0075] For example, the first piece of information may include parameters that specify a first beam number combination for a first number. The terminal can determine the first beam number combination for a first number based on these parameters.

[0076] Furthermore, for example, the first information may include parameters for indicating at least one first parameter combination corresponding to a first number of first beam number combinations. Based on these parameters, the terminal can determine at least one first parameter combination corresponding to a first number of first beam number combinations.

[0077] Furthermore, for example, the first information may include parameters for indicating a first beam number combination of a first number, and parameters for indicating at least one first parameter combination corresponding to the first beam number combination of a first number. Based on the above-mentioned parameters, the terminal can determine a first beam number combination of a first number, and at least one first parameter combination corresponding to the first beam number combination of a first number.

[0078] Furthermore, this disclosure determines a first beam number combination and at least one corresponding first parameter combination based on the first information, and thereby, when the terminal determines the first beam number combination, which P v This avoids uncertainty about whether to adopt β. This avoids the need to set at least one first parameter combination corresponding to one or more first beam count combinations by additional signaling between the network device and the terminal. This reduces additional signaling overhead.

[0079] The disclosure provides a method for determining a first number of first beamnumber combinations and at least one corresponding first parameter combination by receiving first information, thereby enabling the terminal to report CSI based on the determined first beamnumber combinations and corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0080] In the method for determining communication parameters provided by the embodiments disclosed herein, the first information includes a first link identifier, and the first link identifier and a first beamnumber combination and / or a first parameter combination have a first correspondence. The first correspondence includes at least one of the following: the first link identifier corresponds to one first beamnumber combination; the first link identifier corresponds to a plurality of first beamnumber combinations; or the first link identifier corresponds to one first parameter combination.

[0081] In some embodiments, the first information may include a first link identifier, the first link identifier having a first beam number combination and a first correspondence.

[0082] For example, the first information received by the terminal includes a first link identifier, and this first link identifier has a first correspondence with a first beam number combination. Based on the first link identifier, the terminal can determine a first beam number combination. For example, it can determine a first beam number combination of a first number.

[0083] In some embodiments, the first information may include a first link identifier, the first link identifier having a first correspondence with a first parameter combination.

[0084] For example, the first information received by the terminal includes a first link identifier, and this first link identifier has a first correspondence with a first parameter combination.

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}.

[0089] In some embodiments, the first correspondence includes the first link identifier corresponding to a plurality of first beam number combinations.

[0090] 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}. If the first information includes 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}.

[0091] In some embodiments, the first correspondence includes the first link identifier corresponding to a first parameter combination.

[0092] For example, a first link identifier 1 corresponds to a first parameter combination 1: {{1 / 4,1 / 4, 1 / 8,1 / 8},1 / 2}, and a first link identifier 2 corresponds to a first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}. If the first information includes 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 includes the first link identifier 2, the terminal can determine the first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0093] In some embodiments, the first correspondence includes the first link identifier corresponding to a first beamnumber combination and the first link identifier corresponding to a first parameter combination. That is, each first beamnumber combination corresponds to a first parameter combination.

[0094] For example, a first link identifier 1 corresponds to a first beam combination 1: {2,2,2} and a first parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, and a first link identifier 2 corresponds to a first beam combination 2: {4,4,4} and a first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0095] In some embodiments, the first correspondence includes the first link identifier corresponding to a plurality of first beam number combinations, and the first link identifier corresponding to a single first parameter combination. That is, the plurality of first beam number combinations correspond to a single first parameter combination.

[0096] 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}, and 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}.

[0097] Furthermore, a correspondence can be established between the first beam number combination and the first parameter combination using a link identifier. In this case, the terminal can determine the first beam number combination and the first parameter combination based on the first link identifier, simply by having the first link identifier carried along with the first information.

[0098] In some embodiments, the identifier may be an identity (ID) or an index.

[0099] This disclosure determines a first number of first beamnumber combinations and at least one corresponding first parameter combination based on a link identifier. This allows the terminal to report CSI based on the determined first beamnumber combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0100] In the method for determining communication parameters provided by the embodiments disclosed herein, the first information includes a first beam number combination identifier and a first parameter combination identifier.

[0101] In some embodiments, the first information may include a first beam number combination identifier and a first parameter combination identifier.

[0102] For example, the first information includes at least one first beamnumber 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 beamnumber combination indicated by the first beamnumber combination identifier.

[0103] The terminal can determine a first beam number combination based on a first beam number combination identifier and a first parameter combination based on a first parameter combination identifier.

[0104] In this case, it is not necessary to establish a link for the first beamnumber combination and the first parameter combination. Each terminal can determine the first beamnumber combination by the first beamnumber combination identifier and the first parameter combination by the first parameter combination identifier.

[0105] For example, the first information may include one first beamnumber combination identifier and one first parameter combination identifier. Based on the first beamnumber combination identifier contained in the first information, the terminal can determine a first beamnumber combination indicated by this first beamnumber combination identifier, and based on the first parameter combination identifier contained in the first information, the terminal can determine a first parameter combination indicated by this first parameter combination identifier.

[0106] Furthermore, for example, the first information may include multiple first beamnumber combination identifiers and one first parameter combination identifier. For example, the first information may include a first beamnumber combination identifier 1, a first beamnumber combination identifier 2, and a first parameter combination identifier 1. The terminal can determine the first beamnumber combination 1 based on the first beamnumber combination identifier 1 included in the first information, the terminal can determine the first beamnumber combination 2 based on the first beamnumber combination identifier 2 included in the first information, and the terminal can determine the first parameter combination 1 based on the first parameter combination identifier 1 included in the first information. The first beamnumber combination 1 corresponds to the first parameter combination 1, and the first beamnumber combination 2 corresponds to the first parameter combination 1.

[0107] Furthermore, for example, the first information may include a plurality of first beamnumber combination identifiers and a plurality of first parameter combination identifiers. For example, the first information may include a first beamnumber combination identifier 1, a first beamnumber combination identifier 2, a first parameter combination identifier 1, and a first parameter combination identifier 2. The terminal can determine the first beamnumber combination 1 based on the first beamnumber combination identifier 1 included in the first information, the terminal can determine the first beamnumber combination 2 based on the first beamnumber combination identifier 2 included in the first information, the terminal can determine the first parameter combination 1 based on the first parameter combination identifier 1 included in the first information, and the terminal can determine the first parameter combination 2 based on the first parameter combination identifier 2 included in the first information. The first beamnumber combination 1 corresponds to the first parameter combination 1, and the first beamnumber combination 2 corresponds to the first parameter combination 2.

[0108] This disclosure determines a first number of first beamnumber combinations and at least one corresponding first parameter combination using a first beamnumber combination identifier and a first parameter combination identifier, respectively. This allows the terminal to report CSI based on the determined first beamnumber combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0109] In the method for determining communication parameters provided by the embodiments disclosed herein, the value of the first number includes at least one of 1, 2, and 4.

[0110] In some embodiments, the first number may be one.

[0111] For example, the device determines one first SD basis number combination based on the first piece of information.

[0112] In some embodiments, the first number may be two.

[0113] For example, the terminal determines two first SD basis number combinations based on the first piece of information.

[0114] In some embodiments, the first number may be four.

[0115] For example, the device determines four combinations of first SD basis numbers based on the first piece of information.

[0116] The first number may also be the number of SD basis combinations that the device can support maintaining simultaneously.

[0117] This disclosure provides a plurality of possible cases of a first number, thereby determining a first beamnumber combination of a first number and at least one corresponding first parameter combination by receiving first information. This allows the terminal to report a CSI based on the determined first beamnumber combination and the corresponding first parameter combination, further reducing signaling overhead and improving CJT performance.

[0118] In the method for determining communication parameters provided in the embodiments disclosed herein, Figure 3 is a flowchart of another method for determining communication parameters as shown in the exemplary embodiment. As shown in Figure 3, the method may further include the following step S21.

[0119] In step S21, a second number of second beam number combinations and at least one second parameter combination corresponding to the second number of second beam number combinations are determined.

[0120] In some embodiments, the terminal can determine a second number of second beamnumber combinations and at least one second parameter combination corresponding to this second number of second beamnumber combinations. The second beamnumber combination is a subset of the first beamnumber combination. The second parameter combination is P v It includes and β.

[0121] For example, a terminal can determine a second beam number combination of a second number. The second beam number combination may be a subset of the first beam number combination. For example, if the first beam number combination is {2,4,2}, the second beam number combination may be {4,2}, {2,4}, {2,2}, {4} and / or {2}.

[0122] Furthermore, for example, the terminal can determine at least one second parameter combination corresponding to a second number of second beam number combinations. For example, P corresponding to multiple second beam number combinations vAnd β can be determined, or one P corresponding to multiple second beam number combinations v And β can be determined, that is, P corresponding to multiple second beam number combinations v And β are the same.

[0123] The first beam count combination may be a beam count combination corresponding to N TRPs, and the second beam count combination may be a beam count combination corresponding to the selected TRPs after the terminal has selected some or all of the N TRPs. The terminal may not select some of the TRPs. That is, the number of beams in the first beam count combination is N beams, where N represents the number of non-zero power (NZP) CSI-RS resources included in one CMR configured by the network device, and can also be understood as the number of TRPs. The number of beams in the second beam count combination may be M beams, where M is less than or equal to N.

[0124] For example, if N is 3, the first beam number combination that the network device can configure by the first information may be {2,4,2}, as shown in Table 1 as an example. The network device simultaneously configures P corresponding to this {2,4,2} by the first information. v And β can be set. In the case of a terminal, two or one of the three TRPs can be selected to provide service to the terminal. In this case, the second beam number combination may be {4,2}, {2,4}, {2,2}, {4} and / or {2}. It can be seen that the first beam number combination can correspond to multiple second beam number combinations.

[0125] In some embodiments, the determination of a second number of second beamnumber combinations and at least one second parameter combination corresponding to this second number of second beamnumber combinations can be determined and obtained based on information transmitted from a network device for setting the second number of second beamnumber combinations and at least one second parameter combination corresponding to this second number of second beamnumber combinations, or can be determined and obtained based on a first number of first beamnumber combinations and at least one first parameter combination corresponding to this first number of first beamnumber combinations, and the Disclosure shall not be limited thereto.

[0126] For example, the terminal receives information for setting a second beam number combination of a second number, and at least one second parameter combination corresponding to this second beam number combination of a second number. Based on this information, the terminal determines a second beam number combination of a second number, and at least one second parameter combination corresponding to this second beam number combination of a second number.

[0127] Furthermore, for example, the terminal determines a second number of beam number combinations based on the TRP it has selected and a first number of beam number combinations. The terminal can then determine at least one second parameter combination corresponding to the second beam number combination based on at least one first parameter combination corresponding to the first beam combination.

[0128] Of course, in some cases, the terminal can determine a second beamnumber combination of a second number based on the TRP it has selected and a first beamnumber combination of a first number. It receives information to set at least one second parameter combination corresponding to the second beamnumber combination of a second number. Based on this information, it determines at least one second parameter combination corresponding to the second beamnumber combination of a second number.

[0129] This disclosure allows for the determination of a second beamnumber combination belonging to a subset of a first beamnumber combination, and at least one corresponding second parameter combination. This enables the terminal to report CSI based on the determined second beamnumber combination and the corresponding second parameter combination, further reducing signaling overhead and improving CJT performance.

[0130] In the method for determining communication parameters provided by the embodiments disclosed herein, Figure 4 is a flowchart of another method for determining communication parameters as shown in the exemplary embodiment. As shown in Figure 4, the method may further include the following steps S31 to S32.

[0131] In step S31, the second piece of information is received.

[0132] In some embodiments, the terminal can receive second information.

[0133] For example, a terminal receives second information transmitted from a network device. This second information can be used to set at least one second parameter combination corresponding to a second number of beam number combinations.

[0134] The second information may be referred to as second setting information, second instruction information, and second parameter combination setting information, and this disclosure does not limit the names of the second information.

[0135] In some embodiments, the second information may be the same as or different from the first information.

[0136] For example, the second piece of information and the first piece of information are included in the same RRC signaling. Also, for example, the second piece of information and the first piece of information are included in different RRC signaling.

[0137] In step S32, based on the second information, at least one second parameter combination corresponding to a second number of second beam number combinations is determined.

[0138] In some embodiments, the terminal can determine at least one second parameter combination corresponding to a second number of second beam number combinations based on the second information received in S31.

[0139] For example, the terminal receives second information, which includes corresponding parameters for indicating at least one second parameter combination corresponding to a second number of second beam number combinations. Based on these parameters, the terminal determines at least one second parameter combination corresponding to a second number of second beam number combinations.

[0140] This disclosure determines at least one second parameter combination corresponding to a second number of second beamnumber combinations. This allows the terminal to report CSI based on the determined second beamnumber combination and the corresponding second parameter combination, further reducing signaling overhead and improving CJT performance.

[0141] In the method for determining communication parameters provided by the embodiments disclosed herein, the second information includes a second link identifier, the second link identifier having a second correspondence with a second beamnumber combination and / or a second parameter combination, the second correspondence including at least one of the following: the second link identifier corresponding to one second beamnumber combination; the second link identifier corresponding to multiple second beamnumber combinations; and the second link identifier corresponding to one second parameter combination.

[0142] In some embodiments, the second information may include a second link identifier. The second link identifier has a second correspondence with a second beam number combination.

[0143] For example, the second piece of information received by the terminal includes a second link identifier, and this second link identifier has a second correspondence with a second beam number combination. Based on the second link identifier, the terminal can determine a second beam number combination. For example, it can determine a second beam number combination of a second number.

[0144] In some embodiments, the second information may include a second link identifier. The second link identifier has a second correspondence with a second parameter combination.

[0145] For example, the second information received by the terminal includes a second link identifier, which has a second correspondence with a second parameter combination. Based on the second link identifier, the terminal can determine a second parameter combination. For example, it can determine at least one second parameter combination corresponding to a second number of second beam number combinations.

[0146] In some embodiments, the second information may include a second link identifier. The second link identifier has a second beam number combination, a second parameter combination, and a second correspondence.

[0147] For example, the second information received by the terminal includes a second link identifier, which has a second correspondence with a second beamnumber combination, a second parameter combination. Based on the second link identifier, the terminal can determine a second beamnumber combination and a second parameter combination. For example, it can determine a second number of second beamnumber combinations and at least one second parameter combination corresponding to the second number of second beamnumber combinations.

[0148] In some embodiments, the second correspondence includes the second link identifier corresponding to one second beam number combination.

[0149] For example, a second link identifier 1 corresponds to a second beam combination 1:{2,2}, and a second link identifier 2 corresponds to a second beam combination 2:{2,4}. If the second information includes a second link identifier 1, the terminal can determine the second beam combination 1:{2,2}, or if the second information includes a second link identifier 2, the terminal can determine the second beam combination 2:{2,4}.

[0150] In some embodiments, the second correspondence includes the second link identifier corresponding to a plurality of second beam number combinations.

[0151] 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 includes the second link identifier 1, the terminal can determine the second beam combination 1:{2,2} and the second beam combination 2:{2,4}.

[0152] In some embodiments, the second correspondence includes the second link identifier corresponding to a single second parameter combination.

[0153] For example, a second link identifier 1 corresponds to a second parameter combination 1: {{1 / 4,1 / 4, 1 / 8,1 / 8},1 / 2}, and a second link identifier 2 corresponds to a second parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}. If the second information includes a second link identifier 1, the terminal can determine a second parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, or if the second information includes a second link identifier 2, the terminal can determine a second parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0154] In some embodiments, the second correspondence includes the second link identifier corresponding to one second beam number combination and the second link identifier corresponding to one second parameter combination. That is, each second beam number combination corresponds to one second parameter combination.

[0155] 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}. If the second information includes 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 includes 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}.

[0156] In some embodiments, the second correspondence includes the second link identifier corresponding to a plurality of second beam number combinations, and the second link identifier corresponding to a single second parameter combination. That is, the plurality of second beam number combinations correspond to a single second parameter combination.

[0157] For example, the second link identifier 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}, and the second link identifier 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}. If the second information includes the second link identifier 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 includes the second link identifier 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}.

[0158] Furthermore, a correspondence can be established between the second beam number combination and the second parameter combination using a link identifier. In this case, the terminal can determine the second beam number combination and the second parameter combination based on the second link identifier, simply by having the second link identifier carried to the second information.

[0159] In some embodiments, the identifier may be an ID or an index.

[0160] This disclosure determines a second number of second beamnumber combinations and at least one corresponding second parameter combination based on a link identifier. This allows the terminal to report CSI based on the determined second beamnumber combinations and the corresponding second parameter combinations, further reducing signaling overhead and improving CJT performance.

[0161] In the method for determining communication parameters provided by the embodiments disclosed herein, the second information includes a second beam number combination identifier and a second parameter combination identifier, or the second information includes a second parameter combination identifier.

[0162] In some embodiments, the second information may include a second parameter combination identifier.

[0163] For example, a terminal can determine a second parameter combination based on a second parameter combination identifier in the second information. For example, it may determine one second parameter combination. In this case, this one second parameter combination determined by the terminal can be considered to be used for one or more second beam number combinations. That is, one or more second beam number combinations determined by the terminal can be considered to correspond to the same one second parameter combination, i.e., to the second parameter combination indicated by the second parameter combination identifier.

[0164] In some embodiments, the second information may include a second beam number combination identifier and a second parameter combination identifier.

[0165] For example, the second information includes at least one second beam number 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 number combination indicated by the second beam number combination identifier.

[0166] The terminal can determine a second beam number combination based on a second beam number combination identifier and a second parameter combination based on a second parameter combination identifier.

[0167] In this case, it is not necessary to establish a link for the second beamnumber combination and the second parameter combination. Each terminal can determine the second beamnumber combination by the second beamnumber combination identifier and the second parameter combination by the second parameter combination identifier.

[0168] This disclosure determines a second number of second beamnumber combinations and at least one corresponding second parameter combination using a second beamnumber combination identifier and a second parameter combination identifier, respectively. This allows the terminal to report CSI based on the determined second beamnumber combinations and the corresponding second parameter combinations, further reducing signaling overhead and improving CJT performance.

[0169] In the method for determining communication parameters provided by the embodiments disclosed herein, the second parameter combination and the first parameter combination are the same.

[0170] In some embodiments, the second parameter combination corresponding to the second beam number combination may be the same as the first parameter combination corresponding to the first beam number combination.

[0171] For example, P corresponding to the second beam number combination v and β, and P corresponding to the first beam number combination v And β is the same. In other words, the terminal corresponds to P in the first beam number combination. v And β corresponds to P in the second beam number combination v It can also be used as β.

[0172] This disclosure provides a method for determining a second parameter combination, thereby enabling the terminal to report CSI based on the determined second beam number combination and the corresponding second parameter combination, further reducing signaling overhead and improving CJT performance.

[0173] Based on the same concept, this disclosure further provides a method for determining communication parameters performed by a network device.

[0174] Figure 5 is a flowchart of another method for determining communication parameters as shown in an exemplary embodiment, and as shown in Figure 5, the method is performed by a network device and may include the following step S41.

[0175] In step S41, the first piece of information is transmitted.

[0176] In some embodiments, a network device can transmit first information.

[0177] For example, a network device can transmit a first piece of information to a terminal, and this first piece of information can indicate a first beam number combination of a first number. For example, the first piece of information can indicate an SD basis number combination of a first number.

[0178] Furthermore, for example, a network device can transmit first information to a terminal, and the first information can indicate at least one first parameter combination corresponding to a first number of beam number combinations. The first parameter combination is P v It can include β.

[0179] Furthermore, for example, a network device can transmit first information to a terminal, the first information can indicate a first number of first beam number combinations, and the first information can also indicate at least one first parameter combination corresponding to the first number of beam number combinations.

[0180] For example, if the TRP is 2 and the first number is 1, the first beam count combination for the first number may be {2,2}, {2,4}, {4,2}, or {4,4}. If the first number is 2, the first beam count combination for the first number may be any two of {2,2}, {2,4}, {4,2}, and {4,4}. If the first number is 4, the first beam count combination for the first number may be {2,2}, {2,4}, {4,2}, and {4,4}. Note that one or more digits in each beam count combination are used to represent one or more beam counts in that beam count combination. Each beam count can be understood as the number of beams to be selected for the corresponding CSI-RS resource (or TRP).

[0181] Note P v A larger value indicates a greater number of frequency-domain basis vectors to choose from. A larger value of β indicates a greater number of non-zero coefficients.

[0182] Furthermore, this disclosure determines a first beam number combination and at least one corresponding first parameter combination based on the first information, thereby determining which P when the terminal determines the first beam number combination is the corresponding first parameter combination. v This avoids uncertainty about whether to adopt β. This avoids the need to set at least one first parameter combination corresponding to one or more first beam count combinations by additional signaling between the network device and the terminal. This reduces additional signaling overhead.

[0183] The disclosure determines a first number of first beamnumber combinations and at least one corresponding first parameter combination by receiving first information. This allows the terminal to report CSI based on the determined first beamnumber combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0184] In the method for determining communication parameters provided by the embodiments disclosed herein, the first information includes a first link identifier, the first link identifier having a first correspondence with a first beamnumber combination and / or a first parameter combination. The first correspondence includes at least one of the following: the first link identifier corresponds to one first beamnumber combination; the first link identifier corresponds to a plurality of first beamnumber combinations; or the first link identifier corresponds to one first parameter combination.

[0185] In some embodiments, the first information may include a first link identifier, the first link identifier having a first beam number combination and a first correspondence.

[0186] For example, the first piece of information transmitted from a network device includes a first link identifier, and this first link identifier has a first correspondence with a first beam number combination.

[0187] In some embodiments, the first information may include a first link identifier, the first link identifier having a first correspondence with a first parameter combination.

[0188] For example, the first piece of information transmitted from a network device includes a first link identifier, and this first link identifier has a first correspondence with a first parameter combination.

[0189] In some embodiments, the first information may include a first link identifier, the first link identifier having a first beam number combination and a first parameter combination and a first correspondence.

[0190] For example, the first information transmitted from a network device includes a first link identifier, and this first link identifier has a first correspondence with a first beam number combination and a first parameter combination.

[0191] In some embodiments, the first correspondence includes the first link identifier corresponding to one first beam number combination.

[0192] 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}.

[0193] In some embodiments, the first correspondence includes the first link identifier corresponding to a plurality of first beam number combinations.

[0194] 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}. If the first information includes 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}.

[0195] In some embodiments, the first correspondence includes the first link identifier corresponding to a first parameter combination.

[0196] For example, a first link identifier 1 corresponds to a first parameter combination 1: {{1 / 4,1 / 4, 1 / 8,1 / 8},1 / 2}, and a first link identifier 2 corresponds to a first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}. If the first information includes 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 includes the first link identifier 2, the terminal can determine the first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0197] In some embodiments, the first correspondence includes the first link identifier corresponding to a first beamnumber combination and the first link identifier corresponding to a first parameter combination. That is, each first beamnumber combination corresponds to a first parameter combination.

[0198] For example, a first link identifier 1 corresponds to a first beam combination 1: {2,2,2} and a first parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, and a first link identifier 2 corresponds to a first beam combination 2: {4,4,4} and a first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}. If the first information includes a first link identifier 1, the terminal can determine a first beam combination 1: {2,2,2} and a first parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, or if the first information includes a first link identifier 2, the terminal can determine a first beam combination 2: {4,4,4} and a first parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0199] In some embodiments, the first correspondence includes the first link identifier corresponding to a plurality of first beam number combinations, and the first link identifier corresponding to a single first parameter combination. That is, the plurality of first beam number combinations correspond to a single first parameter combination.

[0200] 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}, and 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}. If the first information includes 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 includes 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}.

[0201] Furthermore, a correspondence can be established between the first beam number combination and the first parameter combination using a link identifier. In this case, only the first link identifier is carried along with the first information, and the terminal determines the first beam number combination and the first parameter combination based on the first link identifier.

[0202] In some embodiments, the identifier may be an ID or an index.

[0203] This disclosure determines a first number of first beamnumber combinations and at least one corresponding first parameter combination based on a link identifier. This allows the terminal to report CSI based on the determined first beamnumber combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0204] In the method for determining communication parameters provided by the embodiments disclosed herein, the first information includes a first beam number combination identifier and a first parameter combination identifier.

[0205] In some embodiments, the first information may include a first beam number combination identifier and a first parameter combination identifier.

[0206] For example, the first information includes at least one first beamnumber 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 beamnumber combination indicated by the first beamnumber combination identifier.

[0207] In this case, it is not necessary to establish a link for the first beamnumber combination and the first parameter combination. This allows each terminal to determine the first beamnumber combination by the first beamnumber combination identifier and the first parameter combination by the first parameter combination identifier.

[0208] For example, the first information may include one first beamnumber combination identifier and one first parameter combination identifier. This allows a terminal to determine a first beamnumber combination indicated by a first beamnumber combination identifier contained in the first information, and to determine a first parameter combination indicated by a first parameter combination identifier contained in the first information.

[0209] Furthermore, for example, the first information may include multiple first beamnumber combination identifiers and one first parameter combination identifier. For example, the first information may include a first beamnumber combination identifier 1, a first beamnumber combination identifier 2, and a first parameter combination identifier 1. This allows a terminal to determine the first beamnumber combination 1 based on the first beamnumber combination identifier 1 included in the first information, the terminal to determine the first beamnumber combination 2 based on the first beamnumber combination identifier 2 included in the first information, and the terminal to determine the first parameter combination 1 based on the first parameter combination identifier 1 included in the first information. The first beamnumber combination 1 corresponds to the first parameter combination 1, and the first beamnumber combination 2 corresponds to the first parameter combination 1.

[0210] Furthermore, for example, the first information may include a plurality of first beamnumber combination identifiers and a plurality of first parameter combination identifiers. For example, the first information may include a first beamnumber combination identifier 1, a first beamnumber combination identifier 2, a first parameter combination identifier 1, and a first parameter combination identifier 2. This allows a terminal to determine a first beamnumber combination 1 based on a first beamnumber combination identifier 1 included in the first information, a first beamnumber combination 2 based on a first beamnumber combination identifier 2 included in the first information, a first parameter combination 1 based on a first parameter combination identifier 1 included in the first information, and a first parameter combination 2 based on a first parameter combination identifier 2 included in the first information. The first beamnumber combination 1 corresponds to a first parameter combination 1, and the first beamnumber combination 2 corresponds to a first parameter combination 2.

[0211] This disclosure determines a first number of first beamnumber combinations and at least one corresponding first parameter combination using a first beamnumber combination identifier and a first parameter combination identifier, respectively. This allows the terminal to report CSI based on the determined first beamnumber combinations and the corresponding first parameter combinations, further reducing signaling overhead and improving CJT performance.

[0212] In the method for determining communication parameters provided by the embodiments disclosed herein, the value of the first number includes at least one of 1, 2, and 4.

[0213] In some embodiments, the first number may be one.

[0214] For example, a network device uses first information to specify one first SD basis number combination.

[0215] In some embodiments, the first number may be two.

[0216] For example, a network device uses first information to specify two first SD basis number combinations.

[0217] In some embodiments, the first number may be four.

[0218] For example, a network device uses the first piece of information to specify four first SD basis number combinations.

[0219] The first number may also be the number of SD basis combinations that the device can support maintaining simultaneously.

[0220] This disclosure provides a plurality of possible cases of a first number, thereby determining a first beamnumber combination of a first number and at least one corresponding first parameter combination by receiving first information. This allows the terminal to report a CSI based on the determined first beamnumber combination and the corresponding first parameter combination, further reducing signaling overhead and improving CJT performance.

[0221] In the method for determining communication parameters provided in the embodiments disclosed herein, Figure 6 is a flowchart of another method for determining communication parameters as shown in the exemplary embodiment. As shown in Figure 6, the method may further include the following step S51.

[0222] In step S51, the second piece of information is transmitted.

[0223] In some embodiments, the network device can transmit second information.

[0224] For example, a network device transmits second information to a terminal. This second information can be used to set at least one second parameter combination corresponding to a second beam number combination of a second number. The second beam number combination is a subset of the first beam number combination. The second parameter combination is P v It includes and β.

[0225] For example, the second beam count combination may be a subset of the first beam count combination. The first beam count combination may correspond to N TRPs, and the second beam count combination may correspond to the selected TRPs after the terminal has selected some or all of the N TRPs. The terminal may not select some TRPs. That is, the number of beams in the first beam count combination is N, where N represents the number of NZP CSI-RS resources included in a single CMR configured by the network device, and can be understood as the number of TRPs. The number of beams in the second beam count combination may be M, where M is less than or equal to N.

[0226] For example, if N is 3, the first beam number combination that the network device can configure by the first information may be {2,4,2}, as shown in Table 1 as an example. The network device simultaneously configures P corresponding to this {2,4,2} by the first information. v And β can be set. In the case of a terminal, two or one of the three TRPs can be selected to provide service to the terminal. In this case, the second beam number combination may be {4,2}, {2,4}, {2,2}, {4} and / or {2}. It can be seen that the first beam number combination can correspond to multiple second beam number combinations.

[0227] In some embodiments, the second information may be referred to as second setting information, second instruction information, and second parameter combination setting information, and this disclosure does not limit the names of the second information.

[0228] In some embodiments, the second information may be the same as or different from the first information.

[0229] For example, the second piece of information and the first piece of information are included in the same RRC signaling. Also, for example, the second piece of information and the first piece of information are included in different RRC signaling.

[0230] This disclosure determines at least one second parameter combination corresponding to a second number of second beamnumber combinations. This allows the terminal to report CSI based on the determined second beamnumber combination and the corresponding second parameter combination, further reducing signaling overhead and improving CJT performance.

[0231] In the method for determining communication parameters provided by the embodiments disclosed herein, the second information includes a second link identifier, the second link identifier having a second correspondence with a second beamnumber combination and / or a second parameter combination, the second correspondence including at least one of the following: the second link identifier corresponding to one second beamnumber combination; the second link identifier corresponding to multiple second beamnumber combinations; and the second link identifier corresponding to one second parameter combination.

[0232] In some embodiments, the second information may include a second link identifier. The second link identifier has a second correspondence with a second beam number combination.

[0233] For example, the second piece of information transmitted from the network device includes a second link identifier, and this second link identifier has a second correspondence with a second beam number combination.

[0234] In some embodiments, the second information may include a second link identifier. The second link identifier has a second correspondence with a second parameter combination.

[0235] For example, the second piece of information transmitted from the network device includes a second link identifier, and this second link identifier has a second correspondence with a second parameter combination.

[0236] In some embodiments, the second information may include a second link identifier. The second link identifier has a second beam number combination, a second parameter combination, and a second correspondence.

[0237] For example, the second piece of information transmitted from the network device includes a second link identifier, which has a second correspondence with a second beam number combination, a second parameter combination.

[0238] In some embodiments, the second correspondence includes the second link identifier corresponding to one second beam number combination.

[0239] For example, a second link identifier 1 corresponds to a second beam combination 1:{2,2}, and a second link identifier 2 corresponds to a second beam combination 2:{2,4}. If the second information includes a second link identifier 1, the terminal can determine the second beam combination 1:{2,2}, or if the second information includes a second link identifier 2, the terminal can determine the second beam combination 2:{2,4}.

[0240] In some embodiments, the second correspondence includes the second link identifier corresponding to a plurality of second beam number combinations.

[0241] 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 includes the second link identifier 1, the terminal can determine the second beam combination 1:{2,2} and the second beam combination 2:{2,4}.

[0242] In some embodiments, the second correspondence includes the second link identifier corresponding to a single second parameter combination.

[0243] For example, a second link identifier 1 corresponds to a second parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, and a second link identifier 2 corresponds to a second parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}. If the second information includes a second link identifier 1, the terminal can determine a second parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, or if the second information includes a second link identifier 2, the terminal can determine a second parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0244] In some embodiments, the second correspondence includes the second link identifier corresponding to one second beam number combination and the second link identifier corresponding to one second parameter combination. That is, each second beam number combination corresponds to one second parameter combination.

[0245] 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}. If the second information includes 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 includes 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}.

[0246] In some embodiments, the second correspondence includes the second link identifier corresponding to a plurality of second beam number combinations, and the second link identifier corresponding to a single second parameter combination. That is, the plurality of second beam number combinations correspond to a single second parameter combination.

[0247] For example, the second link identifier 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}, and the second link identifier 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}. If the second information includes a second link identifier 1, the terminal can determine a second beam combination 1: {2,2}, a second beam combination 2: {2,4}, and a second parameter combination 1: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 2}, or if the second information includes a second link identifier 2, the terminal can determine a second beam combination 3: {2}, a second beam combination 4: {4}, and a second parameter combination 2: {{1 / 4,1 / 4,1 / 8,1 / 8},1 / 4}.

[0248] Furthermore, a correspondence can be established between the second beam number combination and the second parameter combination using a link identifier. In this case, the terminal can determine the second beam number combination and the second parameter combination based on the second link identifier, simply by having the second link identifier carried in the second information.

[0249] In some embodiments, the identifier may be an ID or an index.

[0250] This disclosure determines a second number of second beamnumber combinations and at least one corresponding second parameter combination based on a link identifier. This allows the terminal to report CSI based on the determined second beamnumber combinations and the corresponding second parameter combinations, further reducing signaling overhead and improving CJT performance.

[0251] In the method for determining communication parameters provided by the embodiments disclosed herein, the second information includes a second beam number combination identifier and a second parameter combination identifier, or the second information includes a second parameter combination identifier.

[0252] In some embodiments, the second information may include a second parameter combination identifier.

[0253] For example, a second parameter combination identifier contained in the second information can be used by the terminal to determine a second parameter combination. For example, one second parameter combination is determined. In this case, this one second parameter combination determined by the terminal can be considered to be used for one or more second beam number combinations. That is, one or more second beam number combinations determined by the terminal can be considered to correspond to the same one second parameter combination, i.e., to the second parameter combination indicated by the second parameter combination identifier.

[0254] In some embodiments, the second information may include a second beam number combination identifier and a second parameter combination identifier.

[0255] For example, the second information includes at least one second beam number 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 number combination indicated by the second beam number combination identifier.

[0256] In this case, it is not necessary to establish a link for the second beamnumber combination and the second parameter combination. This allows each terminal to determine the second beamnumber combination by the second beamnumber combination identifier and the second parameter combination by the second parameter combination identifier.

[0257] This disclosure determines a second number of second beamnumber combinations and at least one corresponding second parameter combination using a second beamnumber combination identifier and a second parameter combination identifier, respectively. This allows the terminal to report CSI based on the determined second beamnumber combinations and the corresponding second parameter combinations, further reducing signaling overhead and improving CJT performance.

[0258] In the method for determining communication parameters provided by the embodiments disclosed herein, the second parameter combination and the first parameter combination are the same.

[0259] In some embodiments, the second parameter combination corresponding to the second beam number combination may be the same as the first parameter combination corresponding to the first beam number combination.

[0260] For example, P corresponding to the second beam number combination v and β, and P corresponding to the first beam number combination v And β is the same. In other words, the terminal corresponds to P in the first beam number combination. v And β corresponds to P in the second beam number combination v It can also be used as β.

[0261] This disclosure provides a method for determining a second parameter combination, thereby enabling the terminal to report CSI based on the determined second beam number combination and the corresponding second parameter combination, further reducing signaling overhead and improving CJT performance.
