It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0039] The following, in conjunction with the accompanying drawings, describes in detail the port multiplexing method, apparatus, terminal, network-side equipment, and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0040] In NR systems, CSI-RS has a wide range of functions and can be used for channel state information (CSI) measurement, beam measurement, interference measurement, rate matching, and time / frequency tracking. Specifically, CSI-RS can be roughly divided into the following two categories:

[0041] 1. Non-Zero Power CSI-RS (NZP-CSI-RS), used for at least one of the following:

[0042] CSI measurement: measurement of pre-coding matrix indication (PMI), rank indication (RI), channel quality indication (CQI), layer indication (LI);

[0043] Beam measurement: measures Layer-1 Reference Signal Received Power (L1-RSRP) and Layer-1 Signal to Interference plus Noise Ratio (L1-SINR) (up to two ports).

[0044] Interference measurement: measuring intra-cell interference, for example, for Multi-User Multiple-Input Multiple-Output (MU-MIMO) scheduling.

[0045] 2. Zero Power CSI-RS (ZP-CSI-RS), which meets at least one of the following requirements:

[0046] To inform the terminal that a certain resource is occupied by the CSI-RS / CSI interference measurement (CSI-IM) of other terminals;

[0047] The terminal cannot assume that there is no transmit power on the resource element (RE) occupied by the ZP-CSI-RS;

[0048] The terminal only considers that the REs occupied by the ZP-CSI-RS cannot be occupied by the Physical Downlink Shared Channel (PDSCH);

[0049] It has the same structure as NZP-CSI-RS except that it has no actual transmission sequence.

[0050] Currently, the Radio Resource Control (RRC) parameter CSI-RS-ResourceMapping can be used to configure the number of ports, multiplexing mode, time-frequency resources, density and other information 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 the different number of ports, three orthogonal cover code (OCC) multiplexing modes are supported: FD-CDM2, CDM4 (FD2, TD2), and CDM8 (FD2, TD4).

[0051] In addition, the CSI-RS port index can be sorted in the code domain first, then the frequency domain, and finally the time domain. First, starting with the smallest subcarrier index and the smallest symbol index, the port index in the first CDM group is determined. The port index within the same CDM group is determined based on the OCC sequence used. Then, at the same symbol index, the CSI-RS port index in the CDM group on the larger subcarrier is determined. If there are no more CDM groups on the same symbol, the CDM group is determined at the larger symbol index, and the CSI-RS port index is determined.

[0052] The current NR CSI-RS supports a maximum of 32 ports, but resources with different port numbers are not fully compatible. In other words, in some cases, it is difficult to extract orthogonal ports from 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 a 32-port CSI-RS resource based on CDM8 (FD2, TD4); nor is it possible to separate orthogonal 1-port and 2-port CSI-RS from a 32-port CSI-RS resource based on CDM4 (FD2, TD2). This means that different CSI-RS resources need to occupy different time-frequency resources. Although the base station can configure the same CSI-RS resources for all terminals in the network configuration, due to different terminal capabilities, terminals with different capabilities may not support the same CSI-RS ports. In this case, the base station needs to configure different CSI-RS resources for terminals with different capabilities, resulting in a large overall CSI-RS resource overhead in the network. Especially for future larger Massive MIMO (i.e., large-scale multiple-input, multiple-output) scenarios, when introducing larger-port CSI-RS resources (for example, 256 or 512 ports), the number of base station antennas may increase several times, further worsening the CSI-RS resource overhead of the entire network.

[0053] In order to solve the above problems, the embodiment of the application provides a port multiplexing method, apparatus, terminal, network-side equipment and medium. In the port multiplexing method provided in the embodiment of the present application, the 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 port of the first CSI-RS is multiplexed on one or more basic resource sets. Through this solution, since the terminal can receive a first CSI-RS composed of one or more types of basic resource sets, and the port of the first CSI-RS is multiplexed on one or more basic resource sets, it is possible to multiplex a plurality of CSI-RSs 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.

[0054] The embodiment of the present application provides a port multiplexing method, and Figure 2 shows a flow chart of the port multiplexing method provided by the embodiment of the present application. As shown in Figure 2, the port multiplexing method provided by the embodiment of the present application may include the following step 201.

[0055] Step 201: A terminal receives a first reference signal.

[0056] The 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 (ie, REs), and the ports of the first reference signal are multiplexed on one or more basic resource sets.

[0057] Optionally, in an embodiment of the present application, the first reference signal may be used for measuring channel state information; for example, the first reference signal may be a CSI-RS.

[0058] Optionally, in an embodiment of the present application, any two types of basic resource sets among the above-mentioned multiple types of basic resource sets include different numbers of resource units.

[0059] Optionally, in an embodiment of the present application, when a basic resource set includes a resource unit, a port of the first reference signal may be mapped to the basic resource set.

[0060] Optionally, in an embodiment of the present application, when a basic resource set includes multiple resource units, one or more ports of the first reference signal may be mapped to the basic resource set.

[0061] It should be noted that the embodiments of the present application are illustrated by taking one resource unit corresponding to one subcarrier and one symbol as an example. In actual implementation, one resource unit can correspond to any of the following items: one subcarrier and one symbol, multiple subcarriers and one symbol, one subcarrier and multiple symbols, multiple subcarriers and multiple symbols; the specific details can be determined according to actual needs, and the embodiments of the present application are not limited.

[0062] Optionally, in an embodiment of the present application, each type of basic resource set of the one or more types mentioned above includes multiple resource units.

[0063] The above-mentioned multiple resource units may include at least one of the following 1.1 to 1.4:

[0064] 1.1. Multiple resource units that are continuous or non-continuous in the frequency domain at the same time domain position;

[0065] 1.2. Multiple resource units that are continuous or non-continuous in the time domain at the same frequency domain position;

[0066] 1.3. Multiple resource units occupying at least one time domain location;

[0067] 1.4. Multiple frequency domain units occupying at least one frequency domain position.

[0068] Optionally, in an embodiment of the present application, when the above-mentioned multiple resource units include multiple non-continuous resource units at the same time domain position, the multiple resource units can be multiple resource units with an interval of X resource units (i.e., multiple resource units with equal frequency domain intervals), where X is a positive integer; or, the multiple resource units can be multiple continuous resource units of some resource units, and the continuous resource units can be a resource unit group, and there are intervals between different resource unit groups.

[0069] Optionally, in an embodiment of the present application, when the above-mentioned multiple resource units include multiple non-continuous resource units at the same frequency domain position, the multiple resource units can be multiple resource units with an interval of Y symbols (that is, multiple resource units with equal time domain intervals), where Y is a positive integer, or, the multiple resource units can be multiple continuous resource units of some resource units, and the continuous resource units can be a resource unit group, and there are intervals between different resource unit groups.

[0070] In an embodiment of the present application, since the multiple resource units included in each type of basic resource set mentioned above can be at least one item from 1.1 to 1.4 mentioned above, the composition pattern of each type of basic resource set can be enriched, thereby improving the flexibility of multiplexing the port of the first reference signal on the one or more basic resource sets mentioned above.

[0071] Optionally, in the embodiment of the present application, the port of the first reference signal may be multiplexed in at least one of the following manners 2.1 to 2.4:

[0072] 2.1. Multiplexing on a basic resource set through FD-OCC sequence;

[0073] 2.2. Multiplexing on a basic resource set through TD-OCC sequence;

[0074] 2.3. Multiplexing between multiple basic resource sets through TDM;

[0075] 2.4. Multiplexing between multiple basic resource sets through FDM.

[0076] Optionally, in an embodiment of the present application, when the above-mentioned multiple resource units include the above-mentioned 1.1 (i.e., multiple resource units that are continuous or non-continuous in the frequency domain at the same time domain position), the ports of the above-mentioned first reference signal can be multiplexed in the manner of the above-mentioned 2.1 (i.e., multiplexing through the FD-OCC sequence on a basic resource set); if the number of ports of the above-mentioned first reference signal is 1, the above-mentioned FD-OCC sequence can be understood as an all-1 sequence.

[0077] Optionally, in an embodiment of the present application, when the above-mentioned multiple resource units include the above-mentioned 1.2 (i.e., multiple resource units that are continuous or non-continuous in the time domain at the same frequency domain position), the ports of the above-mentioned first reference signal can be multiplexed in the manner of the above-mentioned 2.2 (i.e., multiplexing through the TD-OCC sequence on a basic resource set); if the number of ports of the above-mentioned first reference signal is 1, the above-mentioned TD-OCC sequence can be understood as an all-1 sequence.

[0078] Optionally, in an embodiment of the present application, when the multiple resource units include at least one of the following A to D, the above-mentioned 1.3 (i.e., multiple resource units occupying at least one time domain position), and the above-mentioned 1.4 (i.e., multiple frequency domain units occupying at least one frequency domain position), the port of the above-mentioned first reference signal may be multiplexed using at least one of the manner in the above-mentioned 2.1 (i.e., a manner of multiplexing using an FD-OCC sequence on a basic resource set) and the manner in the above-mentioned 2.2 (i.e., a manner of multiplexing using a TD-OCC sequence on a basic resource set):

[0079] A. Multiple resource units that are continuous in the frequency domain at the same time domain position, and multiple resource units that are continuous in the time domain at the same frequency domain position;

[0080] B. Multiple resource units that are continuous in the frequency domain at the same time domain position, and multiple resource units that are non-contiguous in the time domain at the same frequency domain position;

[0081] C. Multiple resource units that are non-contiguous in the frequency domain at the same time domain position, and multiple resource units that are continuous in the time domain at the same frequency domain position;

[0082] D. Multiple resource units that are non-contiguous in the frequency domain at the same time domain position, and multiple resource units that are non-contiguous in the time domain at the same frequency domain position.

[0083] Optionally, in an embodiment of the present application, when the above-mentioned multiple resource units include at least one of the above-mentioned 1.3 (i.e., multiple resource units occupying at least one time domain position) and the above-mentioned 1.4 (i.e., multiple frequency domain units occupying at least one frequency domain position), the port of the above-mentioned first reference signal may also not be multiplexed based on the OCC sequence; at this time, one port of the first reference signal is mapped to multiple resource units in a basic resource set.

[0084] Optionally, in an embodiment of the present application, the above-mentioned FD-OCC sequence or the above-mentioned TD-OCC sequence may include at least one of the following: a Walsh sequence (i.e., a Walsh sequence), a discrete Fourier transform (DFT) sequence, a Grassmann sequence, and a computer generated sequence (CGS).

[0085] Optionally, in an embodiment of the present application, when the multiple resource units include at least one of 1.1 to 1.4, the port of the first reference signal may also be multiplexed in at least one of TDM and FDM.

[0086] In the embodiment of the present application, since the port of the above-mentioned first reference signal can be multiplexed through at least one of the above-mentioned methods 2.1 to 2.4, the port of the first reference signal can be multiplexed in different ways, thereby improving the flexibility of reference signal port multiplexing.

[0087] Optionally, in an embodiment of the present application, each type of basic resource set mentioned above includes multiple resource units, and the length of the first sequence may be related to the number of first resource units.

[0088] The first sequence is the FD-OCC sequence, and the first resource unit is a plurality of resource units in the frequency domain; or the first sequence is the TD-OCC sequence, and the first resource unit is a plurality of resource units in the time domain.

[0089] Optionally, in an embodiment of the present application, the length of the first sequence is related to the number of the first resource units, which can be understood as: the length of the first sequence is equal to or a multiple of the number of resource units included in the first resource unit.

[0090] For example, the first resource unit includes K resource units, and the length of the first sequence is K or an integer multiple of K, where K is a positive integer.

[0091] In an embodiment of the present application, since the length of the above-mentioned first sequence can be related to the number of the above-mentioned first resource units, the ports of the above-mentioned 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 the reference signal port multiplexing.

[0092] The port multiplexing method provided in the embodiment of the present application is exemplarily described below with reference to the accompanying drawings.

[0093] For example, taking the first reference signal as CSI-RS, as shown in Figure 3, a basic resource set includes one RE. In this case, 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 mapped to (or occupy) multiple REs within one RB.

[0094] As another example, taking the first reference signal as CSI-RS, as shown in FIG4 , a basic resource set includes 2 REs.

[0095] Among them, for basic resource set 2-1, it occupies 2 consecutive REs on the same symbol; this pattern is suitable for scenarios with small frequency domain delay and is conducive to channel measurement in the frequency domain. For basic resource set 2-2, it occupies 2 non-continuous REs on the same symbol, where the interval between the 2 REs is 1; compared with basic resource set 2-1, the advantage of this pattern is that it obtains frequency domain diversity gain by being more discrete in the frequency domain. For basic resource set 2-3, it occupies 2 continuous REs in the time domain on the same subcarrier; this pattern is suitable for scenarios with large delay spread but low mobile speed (Doppler). For basic resource set 2-4, it occupies 2 non-continuous REs in the time domain on the same subcarrier, where the interval between the two REs is 1; compared with basic resource set 2-3, the advantage of this pattern is that it obtains time domain diversity gain by being more discrete in the time domain, and is also conducive to the estimation and processing of time domain characteristics such as frequency offset. For 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 basic resource sets 2-1 to 2-4, this pattern can simultaneously obtain diversity gain in the frequency domain and time domain, and can also be used to achieve close measurement effects while reducing the resource occupancy overhead of CSI-RS.

[0096] For basic resource sets 2-1 and 2-2, when used to map one CSI-RS port, there is no need to use an OCC sequence (or it is understood that the OCC sequence is all 1s, the same below) for CDM multiplexing of the port; when used to map two CSI-RS ports, the two CSI-RS ports can be CDM multiplexed using an OCC sequence of length 2 (i.e., FD-OCC). For basic resource sets 2-3 and 2-4, when used to map one CSI-RS port, there is no need to use an OCC sequence for CDM multiplexing of the port; when used to map two CSI-RS ports, the two CSI-RS ports can be CDM multiplexed using an OCC sequence of length 2 (i.e., TD-OCC). For basic resource sets 2-5, when used to map one CSI-RS port, there is no need to use an OCC sequence for CDM multiplexing of the port; when used to map two CSI-RS ports, the two CSI-RS ports can still be multiplexed using an OCC sequence of length 2; in this case, the elements in the OCC sequence correspond (or map) one-to-one to the two REs. The mapping rule of the OCC sequence can be to first map from low to high in the frequency domain index and then from low to high in the time domain index, or first map from low to high in the time domain index and then from low to high in the frequency domain index.

[0097] As another example, taking the first reference signal as CSI-RS, as shown in FIG5 , a basic resource set includes 4 REs.

[0098] Among them, for 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 basic resource set 4-1. When 1 CSI-RS port is multiplexed, no OCC sequence is required; when 2 CSI-RS ports are multiplexed, a FD-OCC with a length of 2 is used for multiplexing on the first subcarrier and the second subcarrier of the first symbol, and a FD-OCC with a length of 2 is used for multiplexing on the first subcarrier and the second subcarrier of the second symbol, or a TD-OCC with a length of 2 is used for multiplexing on the first symbol and the second symbol of the first subcarrier, and a TD-OCC with a length of 2 is used for multiplexing on the first symbol and the second symbol of the second subcarrier; when 4 CSI-RS ports are multiplexed, a FD-OCC sequence with a length of 2 and a TD-OCC sequence with a length of 2 are used simultaneously for orthogonal multiplexing of the 4 ports.

[0099] For the basic resource set 4-2, it occupies 2 consecutive symbols, and occupies the first subcarrier and the second subcarrier on the first symbol, and occupies the second subcarrier and the third subcarrier on the second symbol. This pattern is conducive to obtaining frequency domain diversity gain, and is also used to measure and process time domain characteristics such as frequency offset. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-2. When 1 CSI-RS port is multiplexed, there is no need to use the OCC sequence; when 2 CSI-RS ports are multiplexed, the first subcarrier and the second subcarrier on the first symbol can use a FD-OCC sequence of length 2 to multiplex the 2 ports. At the same time, the second subcarrier and the third subcarrier on the second symbol also use a FD-OCC sequence of length 2 to multiplex the 2 ports. At this time, the two REs on the second symbol can also be regarded as repetitions or frequency hopping of the RE on the first symbol; when 4 CSI-RS ports are multiplexed , the first subcarrier and the second subcarrier of the first symbol, and the second subcarrier and the third subcarrier of the second symbol can use a FD-OCC sequence of length 4 to multiplex 4 ports, or, the first subcarrier and the second subcarrier on the first symbol use a FD-OCC sequence of length 2 to multiplex 4 ports, and the second subcarrier and the third subcarrier on the second symbol also use a FD-OCC sequence of length 2 to multiplex 4 ports, and at the same time, a TD-OCC sequence of length 2 is mapped on the second subcarrier of the first symbol and the second symbol, thereby realizing orthogonal multiplexing of 4 ports.

[0100] For basic resource set 4-3, it occupies 2 consecutive symbols, and occupies the first subcarrier and the second subcarrier on the first symbol, and occupies the third subcarrier and the fourth subcarrier on the second symbol. This pattern is conducive to obtaining frequency domain or time domain diversity gain, and can also be used to reduce the resource occupancy overhead of CSI-RS while achieving a close measurement effect. 1 to 4 CSI-RS ports can be multiplexed on the basic resource set 4-3. When 1 CSI-RS port is multiplexed, there is no need to use the OCC sequence; when 2 CSI-RS ports are multiplexed, the first subcarrier and the second subcarrier on the first symbol can use a FD-OCC sequence of length 2 to multiplex the 2 ports, and at the same time, the third subcarrier and the fourth subcarrier on the second symbol can also use a FD-OCC sequence of length 2 to multiplex the 2 ports. At this time, the two REs on the second symbol can also be regarded as repetitions or frequency hopping of the RE on the first symbol; when 4 CSI-RS ports are multiplexed, the first An FD-OCC sequence with a length of 4 can be used on the first subcarrier and the second subcarrier of the symbol, and the third subcarrier and the fourth subcarrier of the second symbol to multiplex four ports. Alternatively, an FD-OCC sequence with a length of 2 can be used on the first subcarrier and the second subcarrier of the first symbol to multiplex four ports, and an FD-OCC sequence with a length of 2 can also be used on the third subcarrier and the fourth subcarrier of the second symbol to multiplex four ports. At the same time, a TD-OCC sequence with a length of 2 can be mapped on the second subcarrier of the first symbol and the third subcarrier of the second symbol, thereby realizing orthogonal multiplexing of four ports.

[0101] For basic resource set 4-4, it occupies 4 consecutive REs on the same symbol. This pattern is suitable for scenarios with small frequency domain delay and is conducive to channel measurement in the frequency domain. 1 to 4 CSI-RS ports can be multiplexed on basic resource set 4-4. When 1 CSI-RS port is multiplexed, there is no need to use the OCC sequence; when 2 CSI-RS ports are multiplexed, 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 4 CSI-RS ports are multiplexed, a FD-OCC sequence with a length of 4 is used to multiplex the 4 ports.

[0102] For basic resource set 4-5, it occupies 4 REs that are continuous in the time domain on the same subcarrier. This pattern is suitable for scenarios with large delay spread but low mobile speed (Doppler). 1 to 4 CSI-RS ports can be multiplexed on basic resource set 4-5. When 1 CSI-RS port is multiplexed, there is no need to use an OCC sequence; when 2 CSI-RS ports are multiplexed, a TD-OCC with a length of 2 is used for multiplexing on the first symbol and the second symbol, and a TD-OCC with a length of 2 is used for multiplexing on the third symbol and the fourth symbol, or a TD-OCC with a length of 2 is used for multiplexing on the first symbol and the third symbol, and a TD-OCC with a length of 2 is used for multiplexing on the second symbol and the fourth symbol; when 4 CSI-RS ports are used, a TD-OCC sequence with a length of 4 is used to multiplex the 4 ports.

[0103] The mapping rule of the above OCC sequence can be to first map from low to high according to the frequency domain index and then from low to high according to the time domain index; or to first map from low to high according to the time domain index and then from low to high according to the frequency domain index.

[0104] Furthermore, a CSI-RS resource can be constructed using one or more types of basic resource sets. For example, the basic resource set 2-1 and the basic resource set 2-3 can be combined to construct a four-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 described in detail here.

[0105] Optionally, in an embodiment of the present application, the first reference signal may be determined by the terminal according to first information sent by the network side device.

[0106] The first information may include at least one of the following 3.1 to 3.6:

[0107] 3.1. The number of ports for the first reference signal;

[0108] 3.2. At least one basic resource set corresponding to the first reference signal;

[0109] 3.3. The type of the above basic resource collection;

[0110] 3.4. Information about the ports reused in the above basic resource set;

[0111] 3.5. Information about an OCC sequence corresponding to the port of the first reference signal, where the OCC sequence includes at least one of an FD-OCC sequence and a TD-OCC sequence;

[0112] 3.6. Transmission power of the first reference signal.

[0113] In the embodiment of the present application, since the above-mentioned first reference signal can be determined by the terminal according to at least one of the above-mentioned 3.1 to 3.6 sent by the network side device, the terminal can determine the first reference signal according to different information, thereby improving the flexibility of the terminal in determining the first reference signal.

[0114] Optionally, in an embodiment of the present application, the at least one basic resource set includes at least two basic resource sets.

[0115] The at least two basic resource sets may correspond to any of the following:

[0116] Multiple repetitions of a basic resource set (i.e., repetition);

[0117] A first basic resource set binding, wherein the first basic resource set binding includes a plurality of basic resource sets mapped on a plurality of consecutive symbols;

[0118] The second basic resource set bundle includes a plurality of basic resource sets mapped on a plurality of consecutive physical resource blocks (PRBs).

[0119] For example, taking the first reference signal as CSI-RS and the basic resource set as basic resource set 2-1 in FIG4 , two CSI-RS ports are multiplexed on each basic resource set 2-1 based on an FD-OCC sequence of length 2. As shown in FIG6 , the network side configures one CSI-RS resource #1 for 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 one CSI-RS resource #2 for UE2, which occupies four basic resource sets in one RB, and the number of ports of this CSI-RS resource is 8; and configures one CSI-RS resource #3 for UE3, which occupies three basic resource sets in one RB, and the number of ports of this CSI-RS resource is 6; and configures one CSI-RS resource #4 for UE4, which occupies one 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 resources of UE1. At the time-frequency multiplexing location, multiple CSI-RS resources are transmitted simultaneously, and different UEs only need to receive the CSI-RS at their corresponding time-frequency locations. Because all CSI-RS resources use the same basic resource set, multiple CSI-RS resources reuse the same time-frequency resources, reducing the overall CSI-RS occupancy overhead of the network.

[0120] It should be noted that FIG6 only shows a schematic diagram of time-frequency resource occupancy in one RB, and CSI-RS resources can be mapped on multiple RBs, depending on the number of RBs occupied by the CSI-RS resources and their frequency domain density.

[0121] Furthermore, if the default convention is that one basic resource set 2-1 corresponds to two CSI-RS ports, the number of CSI-RS resource ports can be determined based solely on the number of basic resource sets 2-1. If A basic resource sets 2-1 are occupied, the number of CSI-RS resource ports is 2*A.

[0122] In an embodiment of the present application, since the above-mentioned at least two basic resource sets can correspond to: multiple repetitions of the basic resource set, first basic resource set binding or second basic resource set binding, the composition of the above-mentioned first information can be further enriched, thereby further improving the flexibility of determining the first reference signal based on the first information.

[0123] Optionally, in the embodiment of the present application, the number of ports of the first reference signal may be determined according to at least one of the following:

[0124] The number of ports reused in the above basic resource set;

[0125] The number of the above basic resource collections.

[0126] For example, taking the above-mentioned first reference signal as CSI-RS, and the number of ports of the first reference signal is determined according to the number of ports multiplexed in the above-mentioned basic resource set, assuming that two basic resource sets are indicated, one of which multiplexes X CSI-RS ports and indicates M basic resource sets; the other basic resource set multiplexes Y CSI-RS ports and indicates L basic resource sets, then the number of CSI-RS ports is X*M+Y*L; wherein X, M, Y and L are all positive integers.

[0127] For another example, taking the above-mentioned first reference signal as CSI-RS, and the number of ports of the first reference signal is determined according to the number of the above-mentioned basic resource sets, assuming that it is agreed by default that a 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.

[0128] In an embodiment of the present application, since the number of ports of the above-mentioned first reference signal can be determined based on the number of multiplexed ports in the above-mentioned basic resource set and at least one of the number of the above-mentioned basic resource sets, the number of ports of the first reference signal can be determined based on different information, thereby improving the flexibility of determining the number of ports of the first reference signal.

[0129] Optionally, in an embodiment of the present application, the time-frequency resource position corresponding to the first reference signal may be indicated by a bitmap.

[0130] In the embodiment of the present application, since the time-frequency resource position corresponding to the above-mentioned 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.

[0131] Optionally, in the embodiment of the present application, the above bitmap may satisfy at least one of the following 4.1 to 4.3:

[0132] 4.1. The indication range of the bitmap includes at least one frequency domain unit and at least one time domain unit;

[0133] Optionally, in an embodiment of the present application, the at least one frequency domain unit may be at least one PRB.

[0134] Optionally, in an embodiment of the present application, the at least one time domain unit may be at least one time slot.

[0135] 4.2. Each bit in the bitmap corresponds to at least one basic resource set;

[0136] 4.3. The number of the first values ​​in the bitmap is the same as the number of ports of the first reference signal.

[0137] Optionally, in an embodiment of the present application, the first value may be 1.

[0138] In an embodiment of the present application, since the above-mentioned bitmap can satisfy at least one of the above-mentioned 4.1 to 4.3, the time-frequency resource position corresponding to the above-mentioned first reference signal can be indicated by a bitmap that satisfies different conditions, thereby improving the flexibility of indicating the time-frequency resource position corresponding to the first reference signal.

[0139] For example, taking the first reference signal as CSI-RS and the basic resource set as basic resource set 2-1 in FIG. 4 , two CSI-RS ports are multiplexed based on an FD-OCC sequence of length 2 on each basic resource set 2-1. The method for indicating the time-frequency resource position of the CSI-RS resource includes:

[0140] Instruction method 1

[0141] Indicated in the form of a bitmap (the actual occupied basic resource set is represented by 1, and the unoccupied one is represented by 0). The range of the bitmap corresponds to at least one of the default predetermined at least one frequency domain unit and at least one time domain unit. Take the bitmap range of one RB and one time slot as an example, where one RB occupies 12 subcarriers and one time slot contains 14 symbols. As shown in Figure 7, the time-frequency resource position of the CSI-RS resource corresponding to UE1 can be represented by a 6*14 two-dimensional matrix, which is:

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

[0143] Instruction Method 2

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

[0145] As can be seen, indication method 2 can effectively reduce bitmap overhead in the time domain, but the degree of bitmap overhead reduction is proportional to the number of symbols actually occupied by the CSI-RS resource, and a relationship between the actual occupied symbols and the bitmap needs to be established. 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 represent the time-frequency resource position of the CSI-RS resource, where the first row of the matrix corresponds to the first symbol and the second row of the matrix corresponds to the second symbol.

[0146] Indication method 3: Indication is performed in the form of a bitmap, and the range of the bitmap is related to the frequency domain position actually occupied by the CSI-RS resource. When the frequency domain position actually occupied by the CSI-RS resource is determined, its bitmap overhead in the frequency domain can be effectively reduced. When the frequency domain position actually occupied by the CSI-RS resource is the bandwidth of a basic resource set, the range of the bitmap is the bandwidth of a basic resource set and 14 symbols. As shown in Figure 7, the time-frequency resource position of the CSI-RS resource corresponding to UE3 can be represented by a 1*14 one-dimensional vector, and the one-dimensional vector is: [0 0 0 0 0 0 0 0 0 1 1 1 0 0];

[0147] It can be seen that indication method 3 can effectively reduce the bitmap overhead in the frequency domain. The degree of bitmap overhead reduction is related to the actual bandwidth occupied by the CSI-RS resource, and a relationship between the actual occupied bandwidth and the bitmap needs to be established.

[0148] Instruction Method 4

[0149] The indication is performed in the form of a bitmap. The range of the bitmap is related to the frequency domain position and time domain position actually occupied by the CSI-RS resource, that is, a combination of indication methods 2 and 3. Assuming that the range of the bitmap is from the 5th symbol to the 9th symbol and from the 1st subcarrier to the 8th subcarrier, as shown in Figure 7, the time-frequency resource position of the CSI-RS resource corresponding to UE4 can be represented by a 4*5 two-dimensional matrix:

[0150] In addition, a bit in the bitmap can also represent a set of basic resource sets (i.e., including multiple basic resource sets). For example, as shown in Figure 7, the two basic resource sets occupied by UE2 can be bitmapped as a set, and only three bits are needed in the frequency domain to indicate them, which can further reduce the bitmap overhead.

[0151] Optionally, in an embodiment of the present application, the information of the multiplexed ports in the above basic resource set may include at least one of the following:

[0152] The number of ports reused in the above basic resource set;

[0153] The index of the reused port in the above basic resource collection.

[0154] Optionally, in an embodiment of the present application, if there are multiple basic resource sets, the number of ports of the first reference signal actually multiplexed in any two basic resource sets among the multiple basic resource sets may be the same or different.

[0155] For example, taking the first reference signal as CSI-RS and the basic resource set as basic resource set 4-4 in FIG5 , each basic resource set 4-4 can multiplex a maximum of 4 CSI-RS ports based on an FD-OCC sequence of length 4. As shown in FIG8 , the network side configures one 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 one CSI-RS resource #2 for UE2, which occupies one basic resource set in one RB, and the number of ports of this CSI-RS resource is 1; and configures one CSI-RS resource #3 for UE3, which occupies one basic resource set in one RB, and the number of ports of this CSI-RS resource is 2; and configures one CSI-RS resource #4 for UE4, which occupies one basic resource set in one RB, and the number of ports of this CSI-RS resource is 4. So although UE2 (CSI-RS resource #2), UE3 (CSI-RS resource #2), and UE4 (CSI-RS resource #4) all occupy a basic resource set, the number of CSI-RS ports corresponding to a basic resource set in different CSI-RS resources may be different (the network side can configure the number of CSI-RS ports corresponding to a basic resource set, or the protocol defaults to it).

[0156] Among them, for UE1 (CSI-RS resource #1), 4 CSI-RS ports are multiplexed based on the FD-OCC sequence of length 4 on each corresponding basic resource set; for UE2 (CSI-RS resource #2), 1 CSI-RS port is multiplexed based on the FD-OCC sequence of length 4 on each corresponding basic resource set, and UE2 receives CSI-RS based on the corresponding FD-OCC sequence of length 4; for UE3 (CSI-RS resource #3), 2 CSI-RS ports are multiplexed based on the FD-OCC sequence of length 4 on each corresponding basic resource set, and UE3 receives CSI-RS based on the corresponding two FD-OCC sequences of length 4; for UE4 (CSI-RS resource #4), 4 CSI-RS ports are multiplexed based on the FD-OCC sequence of length 4 on each corresponding basic resource set, and UE4 receives CSI-RS based on the corresponding 4 FD-OCC sequences of length 4.

[0157] 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 to the actual number of ports mapped to the basic resource set or the FD-OCC sequence (including the number). Even if the same time-frequency resources are occupied, the number of CSI-RS ports corresponding to different CSI-RS resources can be different, thereby achieving flexible CSI-RS resource configuration and occupancy, reducing the overall occupancy overhead of CSI-RS resources. Different CSI-RS resources only need to perform CSI-RS reception on the corresponding time-frequency resources according to their corresponding FD-OCC sequences.

[0158] It should be noted that Figure 8 only shows a schematic diagram of the time-frequency resource occupancy in one RB, and the CSI-RS resources can be mapped on multiple RBs. For example, when the CSI-RS resources are mapped on multiple RBs, the time domain resources mapped in each RB are shown in Figure 8; the specific situation depends on the number of RBs occupied by the CSI-RS resources and their frequency domain density.

[0159] In the embodiment of the present application, since the information of the multiplexed ports in the above basic resource set may include at least one of the number and index of the multiplexed ports in the above basic resource set, the multiplexed ports can be flexibly determined by at least one of the number and the index.

[0160] Optionally, in this embodiment of the present application, the information of the OCC sequence corresponding to the port of the first reference signal may include at least one of the following 5.1 to 5.3:

[0161] 5.1. The OCC sequence corresponding to the port multiplexed in the basic resource set corresponding to the first reference signal;

[0162] 5.2. The length assumed for the demodulated OCC sequence (i.e., the despreading length);

[0163] 5.3. Length of the OCC sequence.

[0164] Optionally, in an embodiment of the present application, if there are multiple basic resource sets corresponding to the above-mentioned first reference signal, then in any two basic resource sets of the multiple basic resource sets, the OCC sequences or sequence numbers corresponding to the ports of the first reference signal actually multiplexed may be the same or different.

[0165] For example, taking the information of the OCC sequence corresponding to the port of the above-mentioned first reference signal including the above-mentioned 5.2 as an example, when a maximum of 4 ports are multiplexed on a basic resource set, and 4 ports are multiplexed based on an OCC sequence of length 4, if the network side device indicates to the terminal that the number of ports is 2, the terminal can demodulate the OCC sequence based on the assumption that the length is 2 (i.e., the demodulation length).

[0166] In the embodiment of the present application, since the information of the OCC sequence corresponding to the port of the above-mentioned first reference signal can include at least one of the above-mentioned 5.1 to 5.3, the composition of the above-mentioned first information can be further enriched, thereby further improving the flexibility of determining the first reference signal based on the first information.

[0167] Optionally, in the embodiment of the present application, the transmission power may be associated with any one of the following 6.1 to 6.6:

[0168] 6.1. Transmit power of signals (or channels) other than the first reference signal;

[0169] 6.2. Default agreed reference power;

[0170] 6.3. Reference power configured for network-side equipment;

[0171] 6.4. Minimum power of the first basic resource set;

[0172] 6.5. Maximum power of the first basic resource set;

[0173] 6.6. Average power of the first basic resource set;

[0174] The first basic resource set is at least one basic resource set within a predetermined range.

[0175] Optionally, in an embodiment of the present application, the transmission powers on different basic resource sets may be the same or different.

[0176] 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.

[0177] 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.

[0178] 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 different associated information, thereby improving the flexibility of determining the transmission power.

[0179] Optionally, in an embodiment of the present application, the above-mentioned transmission power may correspond to one or more basic resource sets.

[0180] 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, where P is a positive integer.

[0181] Optionally, in an embodiment of the present application, when the above-mentioned transmission power corresponds to multiple basic resource sets, for example, corresponding 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.

[0182] 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.

[0183] Optionally, in an embodiment of the present application, the transmission power corresponding to the basic resource set may be determined by any of the following methods:

[0184] Bitmap-based approach;

[0185] A mapping method that follows a specific corresponding order.

[0186] 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.

[0187] 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.

[0188] In an embodiment of the present application, since the transmission power corresponding to the above-mentioned basic resource set can be determined based on a bitmap or by mapping in a specific corresponding order, the flexibility of determining the transmission power corresponding to the above-mentioned basic resource set can be improved.

[0189] For example, taking the first reference signal as CSI-RS and the basic resource set as basic resource set 2-1 in Figure 4 above as an example, two CSI-RS ports are multiplexed on each basic resource unit 2-1 based on an FD-OCC sequence of length 2. As shown in Figure 9, UE1 is configured with CSI-RS resource #1, which occupies 32 basic resource units in one RB, and the number of ports of this CSI-RS resource is 64; UE2 is configured with CSI-RS resource #2, which occupies 4 basic resource units in one RB, and the number of ports of this CSI-RS resource is 8; UE3 is configured with CSI-RS resource #3, which occupies 3 basic resource units in one RB, and the number of ports of this CSI-RS resource is 6; UE4 is configured with CSI-RS resource #4, which occupies 1 basic resource unit in one RB, and the number of ports of this CSI-RS resource is 2.

[0190] In this case, the transmission power of CSI-RS resources #2, #3, and #4 can be different. For example, the network side configures different transmission powers for CSI-RS resources #2, #3, and #4. The power can be configured directly or reflected through a power offset with other signals / channels. For CSI-RS resource #1, multiple different transmission powers will appear at its corresponding time-frequency locations. That is, at time-frequency locations that overlap with CSI-RS resources #2, #3, and #4, transmission needs to be performed based on the corresponding transmission power of CSI-RS resources #2, #3, and #4. This achieves time-frequency location and power multiplexing of multiple CSI-RS resources. For CSI-RS resource #1, UE1 needs to be informed of the transmission power at the time-frequency locations that overlap with CSI-RS resources #2, #3, and #4 so that UE1 can perform accurate measurements at the receiving end. In this case, the transmission power can be configured with one or more basic resource units as the granularity, allowing UE1 to know the transmission power at different time-frequency locations.

[0191] In the port multiplexing method provided in an embodiment of the present application, since the terminal can receive a first reference signal composed of one or more types of basic resource sets, and the port of the first reference signal is multiplexed on one or more basic resource sets, it is possible to multiplex multiple reference signals with different numbers of ports on the same time-frequency resources, thereby reducing the overall reference signal resource overhead in the network.

[0192] The present invention provides another method for port multiplexing, and Figure 10 shows a flow chart of the method for port multiplexing provided by the present invention. As shown in Figure 10, the method for port multiplexing provided by the present invention may include the following step 301.

[0193] Step 301: A network-side device sends a first reference signal.

[0194] The 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.

[0195] Optionally, in an embodiment of the present application, each type of basic resource set of the one or more types mentioned above includes multiple resource units.

[0196] The above-mentioned multiple resource units may include at least one of the following:

[0197] Multiple resource units that are continuous or non-continuous in the frequency domain at the same time domain position;

[0198] Multiple resource units that are continuous or non-continuous in the time domain at the same frequency domain position;

[0199] a plurality of resource units occupying at least one time domain location;

[0200] A plurality of frequency domain cells occupying at least one frequency domain location.

[0201] Optionally, in the embodiment of the present application, the port of the first reference signal may be multiplexed in at least one of the following ways:

[0202] Multiplexing on a basic resource set through FD-OCC sequence;

[0203] Multiplexing on a basic resource set through TD-OCC sequences;

[0204] Multiplexing between multiple basic resource sets through TDM;
