As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0037] Next, with reference to the accompanying drawings, the port multiplexing method, apparatus, terminal, network-side device, and medium provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0038] In the NR system, the functions of CSI-RS are very extensive and can be used for channel state information (CSI) measurement, beam measurement, interference measurement, rate matching, and time / frequency tracking, etc. Specifically, CSI-RS can be roughly divided into the following two categories:

[0039] 1. Non Zero Power CSI-RS (NZP-CSI-RS), which is used for at least one of the following:

[0040] CSI measurement: measuring Pre-coding Matrix Indication (PMI), Rank Indication (RI), Channel Quality Indication (CQI), Layer Indicator (LI);

[0041] Beam measurement: Measure the Layer-1 Reference Signal Received Power (L1-RSRP) and the Layer-1 Signal to Interference plus Noise Ratio (L1-SINR) (up to 2 ports).

[0042] Interference measurement: Measure the in-cell interference, e.g., for Multi-User Multiple-Input Multiple-Output (MU-MIMO) scheduling.

[0043] 2. Zero Power CSI-RS (ZP-CSI-RS) satisfies at least one of the following:

[0044] To inform the terminal that a certain resource block is occupied by the CSI-RS / CSI Interference Measurement (CSI-IM) of other terminals;

[0045] The terminal cannot consider that there is no transmission power on the Resource Element (RE) occupied by the ZP-CSI-RS;

[0046] The terminal only considers that the RE occupied by the ZP-CSI-RS cannot be occupied by the Physical Downlink Shared Channel (PDSCH);

[0047] Except for having no substantial transmission sequence, it has the same structure as the NZP-CSI-RS.

[0048] Currently, the Radio Resource Control (RRC) parameter CSI-RS-ResourceMapping can be used to configure information such as the number of ports, multiplexing mode, time-frequency resources, density, etc. of CSI-RS resources. In the current NR system, CSI-RS supports a maximum of 32 ports. Among them, different ports can be multiplexed through Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or Code Division Multiplexing (CDM); for CDM, according to different numbers of ports, it also supports three Orthogonal Cover Code (OCC) multiplexing modes: FD-CDM2, CDM4 (FD2, TD2), and CDM8 (FD2, TD4).

[0049] In addition, the CSI-RS port index can be sorted in the order of code domain first, then frequency domain, and finally time domain. First, starting from the smallest subcarrier index and the smallest symbol index, the port index in the first CDM group is determined, and the port indexes within the same CDM group are determined according to the used OCC sequence. Then, the CSI-RS port indexes in the CDM groups on larger subcarriers are determined at the same symbol index; if there are no more CDM groups at the same symbol, then the CDM groups are determined at a larger symbol index, and the CSI-RS port indexes are determined.

[0050] Currently, the maximum number of ports supported by NR CSI-RS is 32. However, the resources with different numbers of ports are not fully compatible with each other. That is, in some cases, it is difficult to extract orthogonal partial ports from the CSI-RS resources with a larger number of ports. For example, it is impossible to separate orthogonal 1-port, 2-port, and 4-port CSI-RS from the 32-port CSI-RS resource based on CDM8 (FD2, TD4); nor can orthogonal 1-port and 2-port CSI-RS be separated from the 32-port CSI-RS resource based on CDM4 (FD2, TD2), etc. This makes different CSI-RS resources occupy different time-frequency resources. Although in the network-side configuration, the base station can configure the same CSI-RS resources for all terminals, due to the different capabilities of the terminals, terminals with different capabilities may not be able to support the same CSI-RS ports. At this time, the base station needs to configure different CSI-RS resources for terminals with different capabilities, resulting in a relatively large overall CSI-RS resource overhead in the network. Especially for future larger Massive MIMO (i.e., massive multiple-input multiple-output) scenarios, when introducing CSI-RS resources with a larger number of ports (such as 256 or 512 ports), the number of antennas of the base station may increase several times, further deteriorating the overall CSI-RS resource overhead of the entire network.

[0051] To solve the above problems, the application embodiments provide a port multiplexing method, apparatus, terminal, network-side device, and medium. In the port multiplexing method provided by the application embodiments, a terminal can receive a first CSI-RS; wherein, the first CSI-RS is composed of one or more types of basic resource sets, each type of basic resource set includes one or more resource units, and the ports of the first CSI-RS are multiplexed on one or more basic resource sets. Through this solution, since the terminal can receive the first CSI-RS composed of one or more types of basic resource sets, and the ports of the first CSI-RS are multiplexed on one or more basic resource sets, it is possible to multiplex multiple CSI-RS with different numbers of ports on the same time-frequency resources, thereby reducing the overall reference signal resource overhead in the network and improving the efficiency of data transmission.

[0052] The application embodiments provide a port multiplexing method. Figure 2 The flowchart of the port multiplexing method provided by the application embodiments is shown. As Figure 2 shown, the port multiplexing method provided by the application embodiments may include step 201 described below.

[0053] Step 201: The terminal receives a first reference signal.

[0054] Among them, the above first reference signal consists of one or more types of basic resource sets, and each type of basic resource set includes one or more resource elements (i.e., REs). The ports of the first reference signal are multiplexed on one or more basic resource sets.

[0055] Optionally, in the embodiments of the present application, the above first reference signal can be used for the measurement of channel state information; for example, the above first reference signal can be CSI-RS.

[0056] Optionally, in the embodiments of the present application, the number of resource elements included in any two types of basic resource sets among the above multiple types of basic resource sets is different.

[0057] Optionally, in the embodiments of the present application, when a basic resource set includes one resource element, one port of the above first reference signal can be mapped on the one basic resource set.

[0058] Optionally, in the embodiments of the present application, when a basic resource set includes multiple resource elements, one or more ports of the above first reference signal can be mapped on the one basic resource set.

[0059] It should be noted that in the embodiments of the present application, it is exemplified by one resource element corresponding to one subcarrier and one symbol. In actual implementation, one resource element can correspond to any one of the following: one subcarrier and one symbol, multiple subcarriers and one symbol, one subcarrier and multiple symbols, multiple subcarriers and multiple symbols; it can be specifically determined according to actual requirements, and the embodiments of the present application do not make limitations.

[0060] Optionally, in the embodiments of the present application, each type of basic resource set in the above one or more types includes multiple resource elements.

[0061] Among them, the above multiple resource elements can include at least one of the following 1.1 to 1.4:

[0062] 1.1. Multiple resource elements that are frequency-domain continuous or discontinuous at the same time-domain position;

[0063] 1.2. Multiple resource elements that are time-domain continuous or discontinuous at the same frequency-domain position;

[0064] 1.3. Multiple resource elements that occupy at least one time-domain position;

[0065] 1.4. Multiple frequency-domain units that occupy at least one frequency-domain position.

[0066] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include multiple resource units that are discontinuous at the same time domain position, the multiple resource units may be multiple resource units with an interval of X resource units (i.e., multiple resource units with an equal frequency domain interval), where X is a positive integer. Alternatively, the multiple resource units may be multiple resource units with some resource units being continuous, and the continuous resource units may form a resource unit group, with an interval between different resource unit groups.

[0067] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include multiple resource units that are discontinuous at the same frequency domain position, the multiple resource units may be multiple resource units with an interval of Y symbols (i.e., multiple resource units with an equal time domain interval), where Y is a positive integer. Alternatively, the multiple resource units may be multiple resource units with some resource units being continuous, and the continuous resource units may form a resource unit group, with an interval between different resource unit groups.

[0068] In the embodiments of the present application, since the multiple resource units included in each type of basic resource set described above may be at least one of 1.1 to 1.4 above

[0069] Therefore, the composition pattern of each type of basic resource set can be enriched, thereby improving the flexibility of multiplexing the ports of the first reference signal on the above one or more basic resource sets.

[0070] Optionally, in the embodiments of the present application, the ports of the first reference signal described above may be multiplexed by at least one of the following methods 2.1 to 2.4:

[0071] 2.1. On a basic resource set, the method of multiplexing through an FD-OCC sequence;

[0072] 2.2. On a basic resource set, the method of multiplexing through a TD-OCC sequence;

[0073] 2.3. Among multiple basic resource sets, the method of multiplexing through TDM;

[0074] 2.4. Among multiple basic resource sets, the method of multiplexing through FDM.

[0075] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include 1.1 above (i.e., multiple resource units that are frequency domain continuous or discontinuous at the same time domain position), the ports of the first reference signal described above may be multiplexed by the method in 2.1 above (i.e., on a basic resource set, the method of multiplexing through an FD-OCC sequence). If the number of ports of the first reference signal is 1, the above FD-OCC sequence may be understood as an all-1 sequence.

[0076] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include the above 1.2 (i.e., multiple resource units that are time-domain continuous or discontinuous at the same frequency-domain position), the ports of the above first reference signal can be multiplexed by the method in the above 2.2 (i.e., the method of multiplexing through TD-OCC sequences on a basic resource set); if the number of ports of the above first reference signal is 1, the above TD-OCC sequence can be understood as an all-1 sequence.

[0077] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include at least one of the following A to D, the above 1.3 (i.e., multiple resource units occupying at least one time-domain position), and the above 1.4 (i.e., multiple frequency-domain units occupying at least one frequency-domain position), the ports of the above first reference signal can be multiplexed by at least one of the methods in the above 2.1 (i.e., the method of multiplexing through FD-OCC sequences on a basic resource set) and the method in the above 2.2 (i.e., the method of multiplexing through TD-OCC sequences on a basic resource set):

[0078] A. Multiple resource units that are frequency-domain continuous at the same time-domain position and multiple resource units that are time-domain continuous at the same frequency-domain position;

[0079] B. Multiple resource units that are frequency-domain continuous at the same time-domain position and multiple resource units that are time-domain discontinuous at the same frequency-domain position;

[0080] C. Multiple resource units that are frequency-domain discontinuous at the same time-domain position and multiple resource units that are time-domain continuous at the same frequency-domain position;

[0081] D. Multiple resource units that are frequency-domain discontinuous at the same time-domain position and multiple resource units that are time-domain discontinuous at the same frequency-domain position.

[0082] Optionally, in the embodiments of the present application, when the above-mentioned multiple resource units include at least one of the above 1.3 (i.e., multiple resource units occupying at least one time-domain position) and the above 1.4 (i.e., multiple frequency-domain units occupying at least one frequency-domain position), the ports of the above first reference signal can also be multiplexed without relying on OCC sequences; at this time, one port of the first reference signal is mapped to multiple resource units in a basic resource set.

[0083] Optionally, in the embodiments of the present application, the above FD-OCC sequence or the above TD-OCC sequence may include at least one of the following: Walsh sequence (i.e., Walsh sequence), Discrete Fourier Transform (DFT) sequence, Grassmann sequence, and Computer Generate Sequence (CGS).

[0084] Optionally, in the embodiments of the present application, when the above multiple resource units include at least one of the above 1.1 to 1.4, the ports of the above first reference signal may also be multiplexed by at least one of TDM and FDM.

[0085] In the embodiments of the present application, since the ports of the above first reference signal can be multiplexed by at least one of the above 2.1 to 2.4, the ports of the first reference signal can be multiplexed in different ways, thereby improving the flexibility of reference signal port multiplexing.

[0086] Optionally, in the embodiments of the present application, each type of basic resource set includes multiple resource units, and the length of the first sequence may be related to the number of the first resource units.

[0087] Wherein, the above first sequence is the above FD-OCC sequence, and the above first resource unit is multiple resource units in the frequency domain; or, the first sequence is the above TD-OCC sequence, and the first resource unit is multiple resource units in the time domain.

[0088] Optionally, in the embodiments of the present application, the length of the above first sequence is related to the number of the above first resource units, which can be understood as: the length of the first sequence is equal to or has a multiple relationship with the number of multiple resource units included in the first resource unit, etc.

[0089] For example, if the above first resource unit includes K resource units, the length of the above first sequence is K or an integer multiple of K, and K is a positive integer.

[0090] In the embodiments of the present application, since the length of the above first sequence can be related to the number of the above first resource units, the ports of the above first reference signal can be multiplexed based on the first sequence whose length is related to the number of the first resource units, thereby improving the accuracy of reference signal port multiplexing.

[0091] Next, with reference to the accompanying drawings, the port multiplexing method provided in the embodiments of the present application will be exemplarily described.

[0092] Exemplarily, taking the above first reference signal as CSI-RS as an example, as Figure 3As shown, a basic resource set includes 1 RE. At this time, only one CSI-RS port is mapped to a basic resource set, but this does not mean that a CSI-RS port can only be mapped to one basic resource set. For example, for a CSI-RS port, the CSI-RS port can be mapped to (or occupy) multiple RBs, and multiple REs within one RB.

[0093] Exemplarily again, taking the above first reference signal as CSI-RS as an example, as Figure 4 shown, a basic resource set includes 2 REs.

[0094] Among them, for the basic resource set 2-1, it occupies 2 consecutive REs on the same symbol; this pattern is applicable to scenarios with relatively small frequency-domain time delay and is beneficial for channel measurement in the frequency domain. For the basic resource set 2-2, it occupies 2 non-consecutive REs on the same symbol, with a gap of 1 between the 2 REs; compared with the basic resource set 2-1, the advantage of this pattern is to obtain frequency-domain diversity gain by being more discrete in the frequency domain. For the basic resource set 2-3, it occupies 2 time-domain consecutive REs on the same subcarrier; this pattern is applicable to scenarios with relatively large delay spread but relatively small mobile speed (Doppler). For the basic resource set 2-4, it occupies 2 time-domain non-consecutive REs on the same subcarrier, with a gap of 1 between the two REs; compared with the basic resource set 2-3, the advantage of this pattern is to obtain time-domain diversity gain by being more discrete in the time domain, and it is also beneficial for the estimation and processing of time-domain characteristics such as frequency offset. For the basic resource set 2-5, it occupies 2 subcarriers and 2 symbols, that is, it occupies the first subcarrier on the first symbol and the second subcarrier on the second symbol; compared with the basic resource sets 2-1 to 2-4, this pattern can obtain diversity gains in both the frequency domain and the time domain, and can also be used to reduce the resource occupancy overhead of CSI-RS in the case of achieving similar measurement effects.

[0095] For the basic resource sets 2-1 and 2-2, when used to map 1 CSI-RS port, there is no need to use the OCC sequence (or it can be understood that the OCC sequence is all 1s, the same below) for CDM multiplexing of the port; when used to map 2 CSI-RS ports, the two CSI-RS ports can be CDM multiplexed through the OCC sequence of length 2 (i.e., FD-OCC). For the basic resource sets 2-3 and 2-4, when used to map 1 CSI-RS port, there is no need to use the OCC sequence for CDM multiplexing of the port; when used to map 2 CSI-RS ports, the two CSI-RS ports can be CDM multiplexed through the OCC sequence of length 2 (i.e., TD-OCC). For the basic resource set 2-5, when used to map 1 CSI-RS port, there is no need to use the OCC sequence for CDM multiplexing of the port; when used to map 2 CSI-RS ports, the two CSI-RS ports can still be multiplexed through the OCC sequence of length 2; at this time, the elements in the OCC sequence correspond one-to-one (or are mapped) to the two REs. Among them, the mapping rule of the OCC sequence can be to map first from the lowest frequency-domain index to the highest, and then from the lowest time-domain index to the highest, or first from the lowest time-domain index to the highest, and then from the lowest frequency-domain index to the highest.

[0096] Exemplarily, taking the above first reference signal as CSI-RS as an example, as Figure 5 shown, a basic resource set includes 4 REs.

[0097] Among them, for the basic resource set 4-1, it occupies 4 REs corresponding to two consecutive subcarriers on two consecutive symbols. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-1. When multiplexing 1 CSI-RS port, there is no need to use the OCC sequence; when multiplexing 2 CSI-RS ports, the FD-OCC of length 2 is used for multiplexing on the first subcarrier and the second subcarrier of the first symbol, and the FD-OCC of length 2 is used for multiplexing on the first subcarrier and the second subcarrier of the second symbol, or the TD-OCC of length 2 is used for multiplexing on the first symbol and the second symbol of the first subcarrier, and the TD-OCC of length 2 is used for multiplexing on the first symbol and the second symbol of the second subcarrier; when multiplexing 4 CSI-RS ports, the FD-OCC sequence of length 2 and the TD-OCC sequence of length 2 are simultaneously used for orthogonal multiplexing of the 4 ports.

[0098] For the basic resource set 4-2, it occupies two consecutive symbols. On the first symbol, it occupies the first and second subcarriers, and on the second symbol, it occupies the second and third subcarriers. This pattern is beneficial for obtaining frequency-domain diversity gain and is also used for measuring and processing time-domain characteristics such as frequency offset. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-2. When multiplexing 1 CSI-RS port, there is no need to use an OCC sequence; when multiplexing 2 CSI-RS ports, a FD-OCC sequence with a length of 2 can be used on the first and second subcarriers of the first symbol for multiplexing of 2 ports. At the same time, a FD-OCC sequence with a length of 2 is also used on the second and third subcarriers of the second symbol for multiplexing of 2 ports. At this time, the two REs on the second symbol can also be regarded as a repetition or frequency hopping of the REs on the first symbol; when multiplexing 4 CSI-RS ports, a FD-OCC sequence with a length of 4 can be used on the first and second subcarriers of the first symbol and the second and third subcarriers of the second symbol for multiplexing of 4 ports. Or, a FD-OCC sequence with a length of 2 is used on the first and second subcarriers of the first symbol for multiplexing of 4 ports, and a FD-OCC sequence with a length of 2 is also used on the second and third subcarriers of the second symbol for multiplexing of 4 ports. At the same time, a TD-OCC sequence with a length of 2 is mapped on the second subcarriers of the first and second symbols, so as to achieve orthogonal multiplexing of 4 ports.

[0099] For the basic resource set 4-3, it occupies two consecutive symbols. On the first symbol, it occupies the first subcarrier and the second subcarrier, and on the second symbol, it occupies the third subcarrier and the fourth subcarrier. This pattern is beneficial for obtaining frequency-domain or time-domain diversity gain, and can also be used to reduce the resource occupancy overhead of CSI-RS when achieving similar measurement effects. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-3. When multiplexing 1 CSI-RS port, no OCC sequence needs to be used; when multiplexing 2 CSI-RS ports, a FD-OCC sequence with a length of 2 can be used on the first subcarrier and the second subcarrier of the first symbol for multiplexing of 2 ports, and at the same time, a FD-OCC sequence with a length of 2 is also used on the third subcarrier and the fourth subcarrier of the second symbol for multiplexing of 2 ports. At this time, the two REs on the second symbol can also be regarded as the repetition or frequency hopping of the REs on the first symbol; when multiplexing 4 CSI-RS ports, a FD-OCC sequence with a length of 4 can be used on the first subcarrier and the second subcarrier of the first symbol, and the third subcarrier and the fourth subcarrier of the second symbol for multiplexing of 4 ports, or a FD-OCC sequence with a length of 2 can be used on the first subcarrier and the second subcarrier of the first symbol for multiplexing of 4 ports, and a FD-OCC sequence with a length of 2 is also used on the third subcarrier and the fourth subcarrier of the second symbol for multiplexing of 4 ports. At the same time, a TD-OCC sequence with a length of 2 is mapped on the second subcarrier of the first symbol and the third subcarrier of the second symbol, so as to achieve orthogonal multiplexing of 4 ports.

[0100] For the basic resource set 4-4, it occupies 4 consecutive REs on the same symbol. This pattern is applicable to scenarios with small frequency-domain time delay and is beneficial for channel measurement in the frequency domain. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-4. When multiplexing 1 CSI-RS port, no OCC sequence needs to be used; when multiplexing 2 CSI-RS ports, a FD-OCC with a length of 2 is used for multiplexing on the first subcarrier and the second subcarrier, and a FD-OCC with a length of 2 is used for multiplexing on the third subcarrier and the fourth subcarrier, or a FD-OCC with a length of 2 is used for multiplexing on the first subcarrier and the third subcarrier, and a FD-OCC with a length of 2 is used for multiplexing on the second subcarrier and the fourth subcarrier; when multiplexing 4 CSI-RS ports, a FD-OCC sequence with a length of 4 is used for multiplexing of 4 ports.

[0101] For the basic resource sets 4-5, they occupy 4 consecutive REs in the time domain on the same subcarrier. This pattern is applicable to scenarios with a relatively large delay spread but a relatively small mobile speed (Doppler). 1 to 4 CSI-RS ports can be multiplexed on the basic resource sets 4-5. When multiplexing 1 CSI-RS port, no OCC sequence is required; when multiplexing 2 CSI-RS ports, TD-OCC with a length of 2 is used for multiplexing on the first and second symbols, and TD-OCC with a length of 2 is also used for multiplexing on the third and fourth symbols, or TD-OCC with a length of 2 is used for multiplexing on the first and third symbols, and TD-OCC with a length of 2 is used for multiplexing on the second and fourth symbols; when multiplexing 4 CSI-RS ports, a TD-OCC sequence with a length of 4 is used for multiplexing the 4 ports.

[0102] Among them, the mapping rule of the above OCC sequence can be to map first from the lowest frequency-domain index to the highest, and then from the lowest time-domain index to the highest; or first from the lowest time-domain index to the highest, and then from the lowest frequency-domain index to the highest.

[0103] In addition, for a CSI-RS resource, it can be constructed through one or more types of basic resource sets. For example, the above basic resource set 2-1 and the above basic resource set 2-3 can be combined to construct a 4-port CSI-RS resource; other basic resource sets can also be combined to construct CSI-RS resources with different numbers of ports, which will not be elaborated here.

[0104] Optionally, in the embodiments of the present application, the above first reference signal can be determined by the terminal according to the first information sent by the network-side device.

[0105] Among them, the above first information may include at least one of the following 3.1 to 3.6:

[0106] 3.1. The number of ports of the above first reference signal;

[0107] 3.2. At least one basic resource set corresponding to the above first reference signal;

[0108] 3.3. The type of the above basic resource set;

[0109] 3.4. Information about the ports multiplexed in the above basic resource set;

[0110] 3.5. Information about the OCC sequence corresponding to the port of the above first reference signal, and the OCC sequence includes at least one of the FD-OCC sequence and the TD-OCC sequence;

[0111] 3.6. The transmission power of the above first reference signal.

[0112] In the embodiments of the present application, since the above first reference signal can be determined by the terminal according to at least one of the above 3.1 to 3.6 sent by the network device, the terminal can determine the first reference signal according to different information, thereby improving the flexibility of the terminal to determine the first reference signal.

[0113] Optionally, in the embodiments of the present application, the above at least one basic resource set includes at least two basic resource sets.

[0114] Among them, the above at least two basic resource sets can correspond to any one of the following:

[0115] Multiple repetitions (i.e., repetition) of the basic resource set;

[0116] Binding of the first basic resource set, which includes multiple basic resource sets mapped on multiple consecutive symbols;

[0117] Binding of the second basic resource set, which includes multiple basic resource sets mapped on multiple consecutive Physical Resource Blocks (PRBs).

[0118] Exemplarily, taking the above first reference signal as CSI-RS and the basic resource set as the basic resource set 2-1 in the above Figure 4 as an example, two CSI-RS ports are multiplexed on each basic resource set 2-1 based on the FD-OCC sequence with a length of 2. As Figure 6As shown in the figure, the network side configures a CSI-RS resource #1 for a User Equipment (UE) 1, which occupies 32 basic resource sets in one RB, and the number of ports of this CSI-RS resource is 64; and configures a CSI-RS resource #2 for UE2, which occupies 4 basic resource sets in one RB, and the number of ports of this CSI-RS resource is 8; and configures a CSI-RS resource #3 for UE3, which occupies 3 basic resource sets in one RB, and the number of ports of this CSI-RS resource is 6; and configures a CSI-RS resource #4 for UE4, which occupies 1 basic resource set in one RB, and the number of ports of this CSI-RS resource is 2. The time-frequency resources occupied by the CSI-RS resources of UE2, UE3, and UE4 are located within the CSI-RS resource of UE1. At the time-frequency multiplexing position, multiple CSI-RS resources are all transmitted, and different UEs only need to perform CSI-RS reception at their corresponding time-frequency positions. Since all CSI-RS resources use the same basic resource set, multiple CSI-RS resources are multiplexed on the same time-frequency resources, thereby reducing the overall CSI-RS occupancy overhead of the network.

[0119] It should be noted that Figure 6 Only the schematic diagram of the time-frequency resource occupancy in one RB is shown in the figure, and the CSI-RS resource can be mapped on multiple RBs, specifically depending on the number of RBs occupied by the CSI-RS resource and its frequency-domain density.

[0120] In addition, if it is defaultly agreed that one basic resource set 2-1 corresponds to 2 CSI-RS ports, then the number of ports of the CSI-RS resource is determined only according to the number of basic resource sets 2-1. When A basic resource sets 2-1 are occupied, the number of ports of this CSI-RS resource is 2*A.

[0121] In the embodiment of the present application, since the above at least two basic resource sets can correspond to: multiple repetitions of the basic resource set, binding of the first basic resource set, or binding of the second basic resource set, the composition of the above first information can be further enriched, thereby further improving the flexibility of determining the first reference signal according to the first information.

[0122] Optionally, in the embodiment of the present application, the number of ports of the above first reference signal can be determined according to at least one of the following:

[0123] The number of ports multiplexed in the above basic resource set;

[0124] The number of the above basic resource sets.

[0125] For example, taking the above first reference signal as CSI-RS, and the number of ports of the first reference signal being determined according to the number of ports multiplexed in the above basic resource set as an example, assuming that two basic resource sets are indicated in total, where one basic resource set multiplexes X CSI-RS ports and M such basic resource sets are indicated; the other basic resource set multiplexes Y CSI-RS ports and L such basic resource sets are indicated, then the number of CSI-RS ports is X * M + Y * L; where X, M, Y, and L are all positive integers.

[0126] For another example, taking the above first reference signal as CSI-RS, and the number of ports of the first reference signal being determined according to the number of the above basic resource sets as an example, assuming that by default, one basic resource set multiplexes A CSI-RS ports, then when B basic resource sets are indicated, the number of CSI-RS ports can be determined as A * B according to the number of basic resource sets; where A and B are both positive integers.

[0127] In the embodiments of the present application, since the number of ports of the above first reference signal can be determined according to at least one of the number of ports multiplexed in the above basic resource set and the number of the above basic resource sets, the number of ports of the first reference signal can be determined according to different information, thereby improving the flexibility of determining the number of ports of the first reference signal.

[0128] Optionally, in the embodiments of the present application, the time-frequency resource position corresponding to the above first reference signal may be indicated by a bitmap (i.e., bitmap).

[0129] In the embodiments of the present application, since the time-frequency resource position corresponding to the above first reference signal can be indicated by a bitmap, that is, the time-frequency resource position can be indicated by 0 and 1 in the bitmap, it is convenient to flexibly indicate the time-frequency resource position.

[0130] Optionally, in the embodiments of the present application, the above bitmap may satisfy at least one of the following 4.1 to 4.3:

[0131] 4.1. The indication range of the bitmap includes at least one frequency domain unit and at least one time domain unit;

[0132] Optionally, in the embodiments of the present application, the above at least one frequency domain unit may be at least one PRB.

[0133] Optionally, in the embodiments of the present application, the above at least one time domain unit may be at least one time slot.

[0134] 4.2. Each bit in the bitmap corresponds to at least one basic resource set;

[0135] 4.3. The number of the first values in the bitmap is the same as the number of ports of the above first reference signal.

[0136] Optionally, in the embodiments of the present application, the above first value may be 1.

[0137] In the embodiments of the present application, since the above bitmap can satisfy at least one of the above 4.1 to 4.3, the time-frequency resource position corresponding to the above first reference signal can be indicated by bitmaps that meet different conditions, thereby improving the flexibility of indicating the time-frequency resource position corresponding to the first reference signal.

[0138] Exemplarily, taking the above first reference signal as CSI-RS and the basic resource set as the basic resource set 2-1 in the above Figure 4 as an example, two CSI-RS ports are multiplexed on each basic resource set 2-1 based on an FD-OCC sequence with a length of 2. The indication method for the time-frequency resource position of the CSI-RS resource includes:

[0139] Indication method 1

[0140] Indication is made in the form of a bitmap (the actually occupied basic resource set is represented by 1, and the unoccupied one is represented by 0), and the range of the bitmap corresponds to at least one of at least one frequency-domain unit and at least one time-domain unit in the default predetermined. Taking the range of the bitmap as one RB and one time slot as an example, where one RB occupies 12 subcarriers and one time slot contains 14 symbols. As Figure 7 shown in the time-frequency resource position of the CSI-RS resource corresponding to UE1, the time-frequency resource position of the CSI-RS resource corresponding to UE1 can be represented by a 6*14 two-dimensional matrix, and this two-dimensional matrix is:

[0141]

[0142] It can be seen that indication method 1 can flexibly indicate any time-frequency resource position, but the overall bitmap overhead is large.

[0143] Indication method 2

[0144] Indication is made in the form of a bitmap, and the range of the bitmap is related to the actually occupied time-domain position of the CSI-RS resource. When the actually occupied time-domain position of the CSI-RS resource is determined, its bitmap overhead in the time domain can be effectively reduced. When the actually occupied time-domain position of the CSI-RS resource is one symbol, the range of the bitmap is one RB and one symbol. As Figure 7The time-frequency resource location of the CSI-RS resource corresponding to UE2 shown in []. The time-frequency resource location of the CSI-RS resource corresponding to UE2 can be characterized by a 6*1 one-dimensional vector, and this one-dimensional vector is:

[0145]

[0146] It can be seen that indication method 2 can effectively reduce the bitmap overhead in the time domain. However, the degree of reduction of the bitmap overhead is related to the number of symbols actually occupied by the CSI-RS resource, and it is necessary to establish the relationship between the symbols actually occupied and the bitmap. For example, when the number of symbols actually occupied by the CSI-RS resource is 2, a 6*2 two-dimensional matrix is required to characterize the time-frequency resource location of the CSI-RS resource. Among them, the first row of the matrix corresponds to the first symbol, and the second row of the matrix corresponds to the second symbol.

[0147] Indication method 3: Indicate in the form of a bitmap. The range of this bitmap is related to the frequency-domain location actually occupied by the CSI-RS resource. When the frequency-domain location actually occupied by the CSI-RS resource is determined, its bitmap overhead in the frequency domain can be effectively reduced. When the frequency-domain location actually occupied by the CSI-RS resource is the bandwidth of a basic resource set, the range of the bitmap at this time is the bandwidth of a basic resource set and 14 symbols. As Figure 7 the time-frequency resource location of the CSI-RS resource corresponding to UE3 shown in []. The time-frequency resource location of the CSI-RS resource corresponding to UE3 can be characterized by a 1*14 one-dimensional vector, and this one-dimensional vector is: [00000000011100];

[0149] It can be seen that indication method 3 can effectively reduce the bitmap overhead in the frequency domain. The degree of reduction of the bitmap overhead is related to the bandwidth actually occupied by the CSI-RS resource, and it is necessary to establish the relationship between the actually occupied bandwidth and the bitmap.

[0150] Indication method 4

[0151] Indicate in the form of a bitmap. The range of this bitmap is related to the frequency-domain location and time-domain location actually occupied by the CSI-RS resource, that is, the combination of indication methods 2 and 3. Assume that the range of this bitmap is from the 5th symbol to the 9th symbol, and from the 1st subcarrier to the 8th subcarrier. As Figure 7 the time-frequency resource location of the CSI-RS resource corresponding to UE4 shown in []. The time-frequency resource location of the CSI-RS resource corresponding to UE4 can be characterized by a 4*5 two-dimensional matrix:

[0152]

[0153] In addition, one bit in the bitmap can also represent a set of basic resource sets (i.e., containing multiple basic resource sets). For example, as Figure 7 shown, the two basic resource sets occupied by UE2 can be bitmapped as a set, and only 3 bits are needed for indication in the frequency domain, thereby further reducing the overhead of the bitmap.

[0154] Optionally, in the embodiments of the present application, the information of the ports multiplexed in the above basic resource sets may include at least one of the following:

[0155] The number of ports multiplexed in the above basic resource sets;

[0156] The index of the ports multiplexed in the above basic resource sets.

[0157] Optionally, in the embodiments of the present application, if the number of the above basic resource sets is multiple, the number of ports of the above first reference signal actually multiplexed in any two of the multiple basic resource sets may be the same or different.

[0158] Exemplarily, taking the above first reference signal as CSI-RS and the basic resource set as the basic resource set 4-4 in the above Figure 5 as an example, up to 4 CSI-RS ports can be multiplexed on each basic resource set 4-4 based on the FD-OCC sequence of length 4. As Figure 8 shown, the network side configures a CSI-RS resource #1 for UE1, which occupies 16 basic resource sets in one RB, and the number of ports of this CSI-RS resource is 64; and configures a CSI-RS resource #2 for UE2, which occupies 1 basic resource set in one RB, and the number of ports of this CSI-RS resource is 1; and configures a CSI-RS resource #3 for UE3, which occupies 1 basic resource set in one RB, and the number of ports of this CSI-RS resource is 2; and configures a CSI-RS resource #4 for UE4, which occupies 1 basic resource set in one RB, and the number of ports of this CSI-RS resource is 4. Then, although UE2 (CSI-RS resource #2), UE3 (CSI-RS resource #2), and UE4 (CSI-RS resource #4) all occupy one basic resource set, the number of CSI-RS ports corresponding to one basic resource set in different CSI-RS resources can be different (the network side can configure the number of CSI-RS ports corresponding to one basic resource set, or it is default agreed by the protocol).

[0159] Among them, for UE1 (CSI-RS resource #1), 4 CSI-RS ports are multiplexed on each corresponding basic resource set based on the FD-OCC sequence with a length of 4; for UE2 (CSI-RS resource #2), 1 CSI-RS port is multiplexed on each corresponding basic resource set based on the FD-OCC sequence with a length of 4, and UE2 receives CSI-RS based on the corresponding FD-OCC sequence with a length of 4; for UE3 (CSI-RS resource #3), 2 CSI-RS ports are multiplexed on each corresponding basic resource set based on the FD-OCC sequence with a length of 4, and UE3 receives CSI-RS based on the corresponding two FD-OCC sequences with a length of 4; for UE4 (CSI-RS resource #4), 4 CSI-RS ports are multiplexed on each corresponding basic resource set based on the FD-OCC sequence with a length of 4, and UE4 receives CSI-RS based on the corresponding 4 FD-OCC sequences with a length of 4.

[0160] It can be seen that the number of ports of a CSI-RS resource is not only related to the number of basic resource sets, but also related to the actual number of ports or FD-OCC sequences (including the number) mapped on the basic resource sets. Even if the same time-frequency resources are occupied, the number of CSI-RS ports corresponding to different CSI-RS resources can be different, so as to achieve flexible CSI-RS resource configuration and occupancy, and reduce the overall occupancy overhead of CSI-RS resources. Different CSI-RS resources only need to receive CSI-RS on the corresponding time-frequency resources according to their corresponding FD-OCC sequences.

[0161] It should be noted that Figure 8 only the schematic diagram of time-frequency resource occupancy in one RB is shown, and the CSI-RS resource can be mapped on multiple RBs. For example, when the CSI-RS resource is mapped on multiple RBs, the time-domain resources mapped in each RB are as Figure 8 shown; it specifically depends on the number of RBs occupied by the CSI-RS resource and its frequency-domain density.

[0162] In the embodiment of the present application, since the information of the ports multiplexed in the above basic resource set may include at least one of the number and index of the ports multiplexed in the above basic resource set, the multiplexed ports can be flexibly determined by at least one of the number and the index.

[0163] Optionally, in the embodiment of the present application, the information of the OCC sequence corresponding to the port of the above first reference signal may include at least one of the following 5.1 to 5.3:

[0164] 5.1. The OCC sequence corresponding to the ports multiplexed in the basic resource set corresponding to the above first reference signal;

[0165] 5.2. The assumed length of the demodulated OCC sequence (i.e., the despreading length);

[0166] 5.3. The length of the OCC sequence.

[0167] Optionally, in the embodiments of the present application, if the number of basic resource sets corresponding to the above first reference signal is multiple, then in any two of the multiple basic resource sets, the OCC sequences or the number of sequences corresponding to the ports of the first reference signal actually multiplexed may be the same or different.

[0168] For example, taking the information of the OCC sequence corresponding to the port of the above first reference signal including the above 5.2 as an example, when a maximum of 4 ports are multiplexed on a certain basic resource set and 4 ports are multiplexed based on an OCC sequence with a length of 4, if the number of ports indicated by the network side device to the terminal is 2, then the terminal can demodulate the OCC sequence based on the assumption of a length of 2 (i.e., the despreading length).

[0169] In the embodiments of the present application, since the information of the OCC sequence corresponding to the port of the above first reference signal may include at least one of the above

[0170] 5.1 to 5.3, the composition of the above first information can be further enriched, thereby further improving the flexibility of determining the first reference signal according to the first information.

[0171] Optionally, in the embodiments of the present application, the above transmission power may be associated with any one of the following 6.1 to 6.6:

[0172] 6.1. The transmission power of other signals (or channels) other than the above first reference signal;

[0173] 6.2. The default reference power;

[0174] 6.3. The reference power configured by the network side device;

[0175] 6.4. The minimum power of the first basic resource set;

[0176] 6.5. The maximum power of the first basic resource set;

[0177] 6.6. The average power of the first basic resource set;

[0178] Among them, the above first basic resource set is at least one basic resource set within a predetermined range.

[0179] Optionally, in an embodiment of the present application, the transmission powers on different basic resource sets may be the same or different.

[0180] Optionally, in an embodiment of the present application, the transmission power may be an offset (ie, compensation) based on any one of the above 6.1 to 6.6.

[0181] Optionally, in an embodiment of the present application, the above-mentioned other signals (or channels) may be: a synchronization channel, a data channel or a control channel, etc.

[0182] In the embodiment of the present application, since the above-mentioned transmission power can be associated with any one of the above-mentioned 6.1 to 6.6, the transmission power can be determined by the associated different information, thereby improving the flexibility of determining the transmission power.

[0183] Optionally, in an embodiment of the present application, the above transmission power may correspond to one or more basic resource sets.

[0184] Optionally, in an embodiment of the present application, when the above-mentioned transmission power corresponds to a basic resource set, if the network indicates P power coefficients, it corresponds to P basic resource sets, and P is a positive integer.

[0185] Optionally, in an embodiment of the present application, when the above-mentioned transmission power corresponds to multiple basic resource sets, for example, corresponds to Q basic resource sets, Q is an integer greater than or equal to 2, if the network indicates P power coefficients, it corresponds to P*Q basic resource sets, where each power coefficient corresponds to Q basic resource sets.

[0186] In the embodiment of the present application, since the above-mentioned transmission power can correspond to one or more basic resource sets, a flexible correspondence between the transmission power and the number of basic resource sets can be achieved.

[0187] Optionally, in the embodiment of the present application, the transmission power corresponding to the above basic resource set may be determined by any of the following methods:

[0188] Bitmap-based approach;

[0189] A mapping method that follows a specific corresponding order.

[0190] Optionally, in an embodiment of the present application, the above-mentioned transmission power can be mapped to one or more basic resource sets based on the above-mentioned bitmap-based method.

[0191] Optionally, in an embodiment of the present application, the above-mentioned specific corresponding order can be the order of code domain first, then frequency domain, and then time domain, that is, the OCC sequence is from small to large, then the frequency domain position is from low to high, and then the time domain position is from low to high to map at least one power parameter to at least one basic resource set.

[0192] In the embodiments of the present application, since the transmission power corresponding to the above basic resource set can be determined by a bitmap-based method or a mapping method according to a specific corresponding order, the flexibility of determining the transmission power corresponding to the above basic resource set can be improved.

[0193] Exemplarily, taking the above first reference signal as CSI-RS and the basic resource set as the basic resource set 2-1 in the above Figure 4 as an example, two CSI-RS ports are multiplexed on each basic resource unit 2-1 based on an FD-OCC sequence with a length of 2. As Figure 9 shown, UE1 is configured with the corresponding CSI-RS resource #1, occupying 32 basic resource units in one RB, and the number of ports of this CSI-RS resource is 64; UE2 corresponds to the CSI-RS resource #2, occupying 4 basic resource units in one RB, and the number of ports of this CSI-RS resource is 8; UE3 corresponds to the CSI-RS resource #3, occupying 3 basic resource units in one RB, and the number of ports of this CSI-RS resource is 6; UE4 corresponds to the CSI-RS resource #4, occupying 1 basic resource unit in one RB, and the number of ports of this CSI-RS resource is 2.

[0194] At this time, the transmission powers of the CSI-RS resources #2, #3, and #4 can be different. For example, the network side configures different transmission powers for the CSI-RS resources #2, #3, and #4. The power can be directly configured, or it can also be reflected by the power offset with other signals / channels. For the CSI-RS resource #1, there will be multiple different transmission powers at its corresponding time-frequency positions, that is, at the time-frequency positions overlapping with the CSI-RS resources #2, #3, and #4, it needs to be transmitted according to the transmission powers corresponding to the CSI-RS resources #2, #3, and #4, thus realizing the multiplexing of the time-frequency positions and powers of multiple CSI-RS resources. For the CSI-RS resource #1, UE1 needs to be informed of the transmission power at the time-frequency positions overlapping with the CSI-RS resources #2, #3, and #4, so that UE1 can correctly measure at the receiving end. At this time, one or more basic resource units can be used as the granularity for configuring the transmission power, so that UE1 can know the transmission powers at different time-frequency positions.

[0195] In the port multiplexing method provided by the embodiments of the present application, since the terminal can receive the first reference signal composed of one or more types of basic resource sets, and the ports of the first reference signal are multiplexed on one or more basic resource sets, multiple reference signals with different numbers of ports can be multiplexed on the same time-frequency resource, thereby reducing the overall reference signal resource overhead in the network.

[0196] Another port multiplexing method is provided in an embodiment of the present application. Figure 10 The flowchart of the port multiplexing method provided in the embodiment of the present application is shown. As Figure 10 shown, the port multiplexing method provided in the embodiment of the present application may include step 301 below.

[0197] Step 301: The network side device sends a first reference signal.

[0198] Wherein, the above first reference signal is composed of one or more types of basic resource sets, each type of basic resource set includes one or more resource units, and the ports of the first reference signal are multiplexed on one or more basic resource sets.

[0199] Optionally, in the embodiment of the present application, each type of basic resource set in the above one or more types includes multiple resource units.
