If the network device needs to support dynamic adjustment of the number of antenna ports, it needs to obtain CSI reports corresponding to different numbers of antenna ports, and the network device also needs to configure CSI-RS measurement resources for different numbers of antenna ports for the terminal device.

Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.
[0086] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:
[0087] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and / or other components.

The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive and execute commands sent by the processor 110.

In the existing protocol, the channel state information is obtained by the terminal device measuring the measurement resources of CSI-RS and then reported to the network device. Therefore, in order to achieve the purpose of dynamically adjusting the number of PDSCH transmission antenna ports by the network device, it is necessary to consider how to configure the measurement resources of CSI-RS with different numbers of ports for the terminal device.

[0133] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, the density (density) and / or code division multiplexing type (cdm-Type) and / or frequency domain range (freqBand) in the high-level parameters of the channel state information reference signals with different numbers of ports are the same.
[0134] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero-power channel state information reference signal resource identifier, the number of ports of the channel state information reference signal to be measured may be determined through downlink control information.

[0136] Optionally, the downlink control information includes a Y-bit maximum port number indication bit. Optionally, the Y-bit code point is used to indicate the maximum number of ports in a measurement set consisting of the number of channels state information reference signal ports to be measured. After obtaining the maximum number of ports, the number of all channels state information reference signal ports to be measured needs to be determined based on the resource pool in which the number of channels state information reference signal ports to be measured is located.
[0137] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, the number of ports of the channel state information reference signals to be measured must be located in the same resource pool, such as the number of ports of the channel state information reference signals to be measured corresponding to the positions set to 1 in the X bit must be located in the same resource pool; similarly, the number of ports of the channel state information reference signals to be measured, such as those determined by the Y bit, must also be located in the same resource pool.
[0138] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the first frequency domain resource allocation (frequencyDomainAllocation) in the high-layer parameters of the channel state information reference signals with different numbers of ports is a subset of the first frequency domain resource allocation (frequencyDomainAllocation) in the high-layer parameters of the channel state information reference signal with the maximum number of ports in the resource pool where the number of ports of the channel state information reference signal to be measured is located.

[0140] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource set identifiers, the first frequency domain resource allocation (frequencyDomainAllocation) in the higher-layer parameters of the channel state information reference signals with different numbers of ports is a subset of the first frequency domain resource (frequencyDomainAllocation) allocation in the higher-layer parameters of the channel state information reference signal with the largest number of ports in the resource pool where the number of ports of the channel state information reference signal to be measured is located.
[0141] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resources or resource set identifiers, the number of ports of the channel state information reference signal to be measured can be determined through wireless resource control information and / or downlink control information.
[0142] Optionally, the number of CSI reference signal ports to be measured is statically configured via radio resource control information. For example, if two numbers of antenna ports need to be measured, the radio resource control information sequentially configures only the CSI reference signal measurement resources corresponding to the two numbers of antenna ports. Alternatively, if the two numbers of antenna ports are 16 and 32, respectively, only the CSI reference signal measurement resources for 16 and 32 ports need to be sequentially configured via radio resource control information. The terminal then obtains the number of CSI reference signal ports to be measured based on the radio resource control information.
[0143] Optionally, the measurement resources of the channel state information reference signals of all antenna ports in the resource pool where the number of ports of the channel state information reference signals to be measured is located can be configured in the wireless resource control information; and then the number of ports of the channel state information reference signals to be measured is determined through the downlink control information.

[0153] Optionally, satisfying a preset rule includes at least one of the following:
[0154] At least one of the first frequency domain resource allocation (frequencyDomainAllocation), the first symbol in the first time domain (firstOFDMSymbolInTimeDomain), and the first symbol in the second time domain (firstOFDMSymbolInTimeDomain2) in the higher layer parameters of the channel state information reference signals with different numbers of ports is the same;
[0155] The first frequency domain resource allocation in the higher layer parameters of the channel state information reference signal with different port numbers is a subset of the first frequency domain resource allocation in the higher layer parameters of the channel state information reference signal with the maximum port number in the resource pool where the port number is located.
[0156] Optionally, channel state information reference signals with different numbers of ports are located in the same code division multiplexing group and / or the same resource pool.
[0157] Optionally, channel state information reference signals with different numbers of ports may have the same non-zero power channel state information reference signal resource identifier.
[0158] Optionally, channel state information reference signals with different numbers of ports may also have different non-zero power channel state information reference signal resource identifiers.
[0159] Optionally, channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource set identifiers.
[0160] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, the RRC configuration of their CSI-RS resource mapping is as follows:
[0161] Optionally, when channel state information reference signals of different port numbers have the same non-zero power channel state information reference signal resource identifier, the resource pool of the number of ports to be measured is determined according to at least one of the high-level parameters code division multiplexing type (cdm-Type) and the number of ports (nrofPorts).
[0162] Optionally, the code division multiplexing type is fd-CDM2. If the resource pool classification method in Table 1 is adopted, there are two resource pools for the number of ports to be measured. If nrofPorts=32, the resource pool for the number of ports to be measured is {p32, p24, p16, p8, p4, p2}; if nrofPorts=24, the resource pool for the number of ports to be measured is 24, 8, 4, 2}.
[0163] Optionally, Table 1 is defined as follows:
[0164] Table 1. Example of port number resource pool
[0165] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero-power channel state information reference signal resource identifier, the number of channels state information reference signals to be measured may be determined according to downlink control information.
[0166] Optionally, the downlink control information includes X bits of port number indication bits, where each bit in the X bits represents the number of antenna ports to be measured. Optionally, the number of channels of the reference signal state information to be measured indicated by the X bits is located in the same resource pool. For example, Table 1 gives an example of a resource pool grouped according to the code division multiplexing type. Taking the code division multiplexing type of fd-CDM2 as an example, if nrofPorts=32, then according to Table 1, the resource pool is {p32, p24, p16, p8, p4, p2}. Optionally, X=8, that is, the port indication bit contains 8 bits, and from the highest bit to the lowest bit, it corresponds to the number of antenna ports p32, p24, p16, p12, p8, p4, p2, and p1 respectively. Then, the bits 00101110 represent that the set of the number of antenna ports to be measured is {p16, p8, p4, p2}.
[0167] Optionally, when channel state information reference signals with different port numbers have the same non-zero power channel state information reference signal resource identifier, another method for determining the port number of the channel state information reference signal to be measured through downlink control information is: optionally, the downlink control information contains Y bits of maximum port number indication bits, and the code point consisting of Y bits is used to indicate the maximum number of antenna ports to be measured. Similarly, taking the resource pools grouped by code division multiplexing type in Table 1 as an example, optionally, the code division multiplexing type is cdm4-FD2-TD2 and nrofPorts = 32. According to Table 1, the resource pool in which the number of antenna ports to be measured is located is {p32, p24, p16, p12, p8}. Optionally, Y is 3 bits, and each 3-bit code point corresponds to an index in the antenna port set {p32, p24, p16, p12, p8, p4, p2, p1}. For example, bits 001 correspond to a maximum number of antenna ports to be measured of 2 ports, 010 corresponds to a maximum number of antenna ports to be measured of 4 ports, and so on. Optionally, the maximum port number indication bit in the downlink control information is 110. Since the number of antenna ports to be measured obtained based on the Y bits is located in the same resource pool, the set of antenna port numbers to be measured is {p12, p8}.
[0168] It should be noted that if the code division multiplexing type is fd-CDM2 and the frequency domain resource allocation configuration is row4, dynamic switching is not performed.
[0169] Optionally, the time-frequency domain mapping resources of the channel state information reference signal corresponding to each number of antenna ports in the resource pool are all subsets of the time-frequency domain mapping resources of the channel state information reference signal corresponding to the maximum number of ports in the resource pool.
[0170] Optionally, the downlink control information may be specific to the terminal device; may be shared by the terminal devices in a preset group; or may be shared by the terminal devices in a preset cell.
[0171] Optionally, when channel state information reference signals of different port numbers have the same non-zero power channel state information reference signal resource identifier, the high-level parameters of each port number, the first frequency domain resource allocation (frequencyDomainAllocation) and / or the first symbol of the first time domain (firstOFDMSymbolInTimeDomain) and / or the first symbol of the second time domain (firstOFDMSymbolInTimeDomain 2) and / or density (density) and / or code division multiplexing type (cdm-type) and / or frequency domain range (freqBand) are configured the same.
[0172] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, the terminal device needs to extract the valid bits in the high-level parameters firstOFDMSymbolInTimeDomain2, firstOFDMSymbolInTimeDomain, and frequencyDomainAllocation of the channel state information reference signal corresponding to the number of antenna ports according to the second preset rule.
[0173] Optionally, when different numbers of channel state information reference signals have different non-zero power channel state information reference signal resource identifiers, each RRC parameter nzp-CSI-RS-ResourceId corresponds to the resource configuration of non-zero power channel state information reference signals for one antenna port number. The RRC parameter nzp-CSI-RS-ResourceId is configured as follows:
[0174] Optionally, the numbers of antenna ports corresponding to channel state information reference signals with different non-zero power channel state information reference signal resource identifiers are located in the same resource pool. For an example of the resource pool, see Table 1.
[0175] It should be noted that Table 1 is only an example of resource pool classification, and other resource pool classification methods are not excluded.
[0176] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the high-level parameters code division multiplexing type (cdm-Type) and / or density (density) and / or the first symbol of the first time domain (firstOFDMSymbolInTimeDomain) and / or the first symbol of the second time domain (firstOFDMSymbolInTimeDomain 2) and / or the frequency domain range (freqBand) of each number of ports are configured the same.
[0177] Optionally, when channel state information reference signals with different port numbers have different non-zero power channel state information reference signal resource identifiers, the value of the high-level parameter first frequency domain resource allocation (frequencyDomainAllocation) of the channel state information reference signal corresponding to each nzp-CSI-RS-ResourceId satisfies a preset rule: the positions set to 1 in the first frequency domain resource allocation (frequencyDomainAllocation) of each port number are all subsets of the positions set to 1 in the first frequency domain resource allocation (frequencyDomainAllocation) of the maximum port number in the resource pool where the port number is located.
[0178] Optionally, the code division multiplexing type (cdm-Type) for each number of antenna ports is configured as fd-CDM2, the maximum number of ports in the resource pool is 32, and the channel state information reference signal resource identifier nzp-CSI-RS-ResourceId for the 32-port channel state information reference signal is 0, frequencyDomainAllocation is other, and the bits are 011110. Then, the higher-layer parameter frequencyDomainAllocation for the 24-port channel state information reference signal is other, and the bit value of frequencyDomainAllocation is a subset of the bit 011110 of the higher-layer parameter frequencyDomainAllocation for the 32-port channel state information reference signal. Optionally, the bit value of frequencyDomainAllocation for the 24-port channel state information reference signal is 011100. Because channel state information reference signals with different numbers of antenna ports have different non-zero-power channel state information reference signal resource identifiers, optionally, the resource identifier nzp-CSI-RS-ResourceId for the 24-port channel state information reference signal is 1. Optionally, the bit value of the frequencyDomainAllocation of port 24 may also be 010110 or 001110, etc., that is, it is sufficient to ensure that the position where the frequencyDomainAllocation of port 24 is set to 1 is a subset of the position where the frequencyDomainAllocation of the maximum number of ports in the resource pool (for example, 32 ports) is set to 1.
[0179] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the time-frequency domain resources of the channel state information reference signals determined according to the frequencyDomainAllocation of each number of ports are multiplexed in the time-frequency domain resource position of the channel state information reference signal with the maximum number of ports in the resource pool to which each number of ports belongs. Optionally, see Figures 7, 8, and 9. Figure 7 is a first example schematic diagram of the processing method according to the second embodiment, showing the time-frequency domain resources occupied by 32 ports; Figure 8 is a second example schematic diagram of the processing method according to the second embodiment, showing the time-frequency domain resources occupied by 24 ports; Figure 9 is a third example schematic diagram of the processing method according to the second embodiment, showing the time-frequency domain resources occupied by 8 ports. As can be seen from the figure, the time-frequency domain resources occupied by 24 ports and 8 ports are both part of the time-frequency domain resources occupied by 32 ports, that is, the channel state information reference signals of 24 ports, 8 ports, and 32 ports reuse the same time-frequency domain resources.
[0180] Optionally, when different numbers of channel state information reference signals have different non-zero power channel state information reference signal resource set identifiers, each RRC parameter nzp-CSI-ResourceSetId corresponds to the resource configuration of non-zero power channel state information reference signals for one antenna port number. The RRC parameter nzp-CSI-ResourceSetId is configured as follows:
[0181] Optionally, the numbers of antenna ports corresponding to channel state information reference signals with different non-zero power channel state information reference signal resource set identifiers are located in the same resource pool. For an example of the resource pool, see Table 1.
[0182] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource set identifiers, the value of the high-layer parameter frequencyDomainAllocation of the channel state information reference signal corresponding to each nzp-CSI-ResourceSetId satisfies a preset rule: the positions set to 1 in the frequencyDomainAllocation of each number of ports are a subset of the positions set to 1 in the frequencyDomainAllocation of the maximum number of ports in the resource pool where the port number is located.
[0183] Optionally, the code division multiplexing type cdm-Type for each number of antenna ports is configured as fd-CDM2, the maximum number of ports in the resource pool is 32, and the channel state information reference signal resource identifier nzp-CSI-ResourceSetId for the 32-port channel state information reference signal is 0, frequencyDomainAllocation is other, and the bits are 011110. Then, the higher-layer parameter frequencyDomainAllocation for the 24-port channel state information reference signal is other, and the value of the frequencyDomainAllocation bits is a subset of the bits 011110 of the higher-layer parameter frequencyDomainAllocation for the 32-port channel state information reference signal. Optionally, the value of the frequencyDomainAllocation bits for the 24-port channel state information reference signal is 011100. Because channel state information reference signals with different numbers of antenna ports have different non-zero-power channel state information reference signal resource set identifiers, optionally, the resource set identifier nzp-CSI-ResourceSetId for the 24-port channel state information reference signal is 1. Optionally, the bit value of the frequencyDomainAllocation of port 24 may also be 010110 or 001110, etc., that is, it is sufficient to ensure that the position where the frequencyDomainAllocation of port 24 is set to 1 is a subset of the position where the frequencyDomainAllocation of the maximum number of ports in the resource pool (for example, 32 ports) is set to 1.
[0184] This embodiment, through the above-mentioned scheme, specifically selects or determines the number of ports of the channel state information reference signal to be measured based on downlink information; selects or determines high-level parameters that meet preset rules for at least one group of channel state information reference signals with a certain number of ports based on downlink information; and selects or determines the time domain resource position and / or frequency domain resource position occupied by the channel state information reference signal in the time slot in which it is located based on the said high-level parameters. Furthermore, the number of ports of the channel state information reference signal to be measured can be dynamically adjusted based on the downlink information to meet the requirements of dynamic antenna port adjustment of network equipment under different energy-saving requirements; and / or, by multiplexing the same time domain resources and / or frequency domain resources between channel state information reference signals with different numbers of antenna ports, interference between channel state information reference signals with different numbers of ports can be reduced.

[0192] Optionally, the code division multiplexing type cdm-Type = fd-CDM2. If the resource pool classification method of Table 1 is adopted, there are two resource pools for the number of antenna ports. If nrofPorts = 32, the resource pool used is {p32, p24, p16, p8, p4, p2}, and / or, if nrofPorts = 24, the resource pool used is {p24, p8, p4, p2}.

For the time domain high-level parameters firstOFDMSymbolInTimeDomain and / or firstOFDMSymbolInTimeDomain2, according to Table 2,
[0196] The operation of the high-level parameter firstOFDMSymbolInTimeDomain or firstOFDMSymbolInTimeDomain2 of port 24 meeting the second preset rule is: firstOFDMSymbolInTimeDomain2=9 and firstOFDMSymbolInTimeDomain=3 can be used at the same time;
[0197] The operation of the high-level parameter firstOFDMSymbolInTimeDomain or firstOFDMSymbolInTimeDomain2 of port 16 that meets the second preset rule is: only the high-level parameter firstOFDMSymbolInTimeDomain=3 is used, and the high-level parameter firstOFDMSymbolInTimeDomain2 does not participate in the configuration of the CSI-RS resource of port 16;
[0198] Similarly, the operation of the 8-port high-level parameters firstOFDMSymbolInTimeDomain and / or firstOFDMSymbolInTimeDomain2 complying with the second preset rule is: only using the high-level parameter firstOFDMSymbolInTimeDomain=3, and the high-level parameter firstOFDMSymbolInTimeDomain2 does not participate in configuring the 8-port CSI-RS resources.

[0200] Alternatively, an example of Table 2 extracted from Table 7.4.1.5.3-1 of 38.211 is as follows:
[0201] Table 2. Example of second rule definition for high-level parameters with different numbers of ports
[0202] This embodiment, through the above-mentioned solution, specifically by having channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, does not increase RRC parameters, does not increase time-frequency domain resources, and can dynamically adjust the number of channel state information reference signal ports to be measured through downlink information (such as downlink control information) to meet the needs of dynamic antenna port adjustment of network devices under different energy-saving requirements. In addition, channel state information reference signals with different numbers of antenna ports reuse the same time-frequency domain resources, which can reduce interference between channel state information reference signals with different numbers of ports.
[0203] Fourth embodiment
[0204] Based on any of the above embodiments of the present application, this embodiment further discloses a processing method.
[0205] Optionally, when channel state information reference signals with different numbers of ports have the same non-zero-power channel state information reference signal resource identifier, the set of antenna port numbers to be measured may be selected or determined according to downlink control information.
[0206] Optionally, the downlink control information includes an X-bit port number indication bit, where X = 8 bits. For example, from LSB (Least Significant Bit) to MSB (Most Significant Bit), the bits correspond to the numbers of antenna ports p1, p2, p4, p8, p12, p16, p24, and p32, respectively. For example, bits 00101110 represent that the number of CSI reference signal ports to be measured is 16, 8, 4, and 2, respectively.
[0207] Optionally, when channel state information reference signals with different port numbers have the same non-zero power channel state information reference signal resource identifier, the maximum number of ports in the set of antenna port numbers to be measured can also be selected or determined based on the downlink control information, and then the set of antenna port numbers to be measured can be selected or determined based on the definition of the resource pool.
[0208] Optionally, according to the high-level parameters code division multiplexing type (cdm-Type) = fd-CDM2 and number of ports (nrofPorts) = 32, and the resource pool shown in Table 1, it can be seen that the resource pool where the set of antenna port numbers to be measured is located is {p32, p24, p16, p8, p4, p2}.
[0209] Optionally, the downlink control information includes Y bits indicating the maximum number of ports, and each code point consisting of Y bits corresponds to an index in {p32, p24, p16, p12, p8, p4, p2, p1}. For example, 000 corresponds to p1, i.e., the maximum number of antenna ports in the set of antenna port numbers to be measured is 1, 001 corresponds to p2, i.e., the maximum number of antenna ports in the set of antenna port numbers to be measured is 2, 010 corresponds to p4, i.e., the maximum number of antenna ports in the set of antenna port numbers to be measured is 4, and so on. If the downlink control information includes Y bits indicating the maximum number of ports = 011, and the resource pool in which the set of antenna port numbers to be measured belongs is {p32, p24, p16, p8, p4, p2}, then the number of ports to be measured is 8 ports, 4 ports, and 2 ports.
[0210] This embodiment uses the above-mentioned scheme, specifically by using fewer bits to indicate the measurement resource configuration information of channel state reference signals with different numbers of ports when the channel state information reference signals with different numbers of ports have the same non-zero power channel state information reference signal resource identifier, thereby further saving the overhead of network equipment.
[0211] Fifth embodiment
[0212] Based on any of the above embodiments of the present application, this embodiment further discloses a processing method.
[0213] Optionally, channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, for example, the non-zero power channel state information reference signal resource identifier corresponding to 32 ports is 1, the non-zero power channel state information reference signal resource identifier corresponding to 24 ports is 3, and so on.
[0214] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, at least one of the high-level parameters of the channel state information reference signals with each number of ports, the first symbol of the first time domain (firstOFDMSymbolInTimeDomain), the first symbol of the second time domain (firstOFDMSymbolInTimeDomain 2), density (density), code division multiplexing type (cdm-type) and frequency domain range (freqBand) are the same.
[0215] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the positions set to 1 in the high-level parameter frequencyDomainAllocation of the channel state information reference signal with each number of ports need to be a subset of the positions set to 1 in the high-level parameter frequencyDomainAllocation of the maximum number of ports in the resource pool.
[0216] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the number of antenna ports to be measured may be directly specified by an RRC message.
[0217] Optionally, if cdm-Type = fd-CDM2 and the resource pool partitioning method in Table 1 is used, the resource pool to which the number of antenna ports to be measured belongs is {p32, p24, p16, p8, p4, p2}. If the RRC message only configures the non-zero-power channel state information reference signal resource identifier for the 4-port channel state information reference signal as 3, the non-zero-power channel state information reference signal resource identifier for the 16-port channel state information reference signal as 5, and the non-zero-power channel state information reference signal resource identifier for the 8-port channel state information reference signal as 6, then the number of antenna ports to be measured is 24 ports, 16 ports, and 8 ports. Since the positions set to 1 in the high-level parameter frequencyDomainAllocation of the channel state information reference signal for each number of ports must be a subset of the positions set to 1 in the high-level parameter frequencyDomainAllocation of the maximum number of ports in the resource pool; and the frequencyDomainAllocation of the maximum number of ports in the resource pool is 32 ports, the high-level parameter frequencyDomainAllocation of the channel state information reference signal for 24 ports can be 010110, the high-level parameter frequencyDomainAllocation of the channel state information reference signal for 16 ports can be 011110, and the high-level parameter frequencyDomainAllocation of the channel state information reference signal for 8 ports can be 010010. Therefore, according to Table 7.4.1.5.3-1 of 38.211 and the rules of frequency domain mapping, the time-frequency domain resources occupied by 24 ports in one RB are shown in Figure 13; referring to Figure 14, Figure 14 is a second example schematic diagram of the processing method shown in the fifth embodiment. According to Table 7.4.1.5.3-1 of 38.211 and the rules of frequency domain mapping, the time-frequency domain resources occupied by 16 ports in one RB are shown in Figure 14; referring to Figure 15, Figure 15 is a third example schematic diagram of the processing method shown in the fifth embodiment, and the time-frequency domain resources occupied by 8 ports in one RB are shown in Figure 15.
[0218] Optionally, the value of the higher-layer parameter frequencyDomainAllocation for the channel state information reference signal of each antenna port is a subset of the higher-layer parameter frequencyDomainAllocation for the channel state information reference signal of the maximum number of ports in the resource pool. That is, taking the maximum number of ports in the resource pool as an example, and frequencyDomainAllocation for 32 ports = 011110, the higher-layer parameter frequencyDomainAllocation for each number of ports only needs to be set to a value in a limited number of bit positions that meet the requirements of Table 7.4.1.5.3-1 of 38.211. For example, according to Table 7.4.1.5.3-1 of 38.211, the channel state information reference signal of 24 ports must have three bit positions set to 1. Therefore, the higher-layer parameter frequencyDomainAllocation for the channel state information reference signal of 24 ports can be 010110, 011100, or 001110, etc.
[0219] This embodiment, through the above-mentioned scheme, specifically realizes the multiplexing of time domain and frequency domain resources of channel state information reference signals with different numbers of ports by having different non-zero power channel state information reference signal resource identifiers at the channel state information reference signals with different numbers of ports, thereby reducing the interference of time domain and frequency domain resources of channel state information reference signals with different numbers of ports; and / or, improves the flexibility of mapping time domain resources and / or frequency domain resources of channel state information reference signals with different numbers of ports.
[0220] Sixth embodiment
[0221] Based on any of the above embodiments of the present application, this embodiment further discloses a processing method.
[0222] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the number of antenna ports to be measured can be determined by the downlink control information, and the RRC message includes the time-frequency resource configuration information of the channel state information reference signals of all antenna ports in the resource pool.
[0223] Optionally, the code division multiplexing type (cdm-Type) = fd-CDM2. If the resource pool partitioning method in Table 1 is used and the resource pool is {p32, p24, p16, p8, p4, p2}, then the RRC message includes the time-frequency resource configuration information of the channel state information reference signal for all antenna ports in the resource pool. Optionally, since each antenna port number has a non-zero power channel state information reference signal resource identifier, the non-zero power channel state information reference signal resource identifier for each antenna port number can be as shown in Table 3:
[0224] Table 3. First example of RRC configuration of channel state information reference signals of different ports
[0225] Optionally, Table 3 is only an example of different numbers of antenna ports having different non-zero-power channel state information reference signal resource identifiers. The resource identifiers of channel state information reference signals with different numbers of ports can be configured by RRC according to specific circumstances.
[0226] Optionally, the resource pool to which each port number belongs is determined according to a code division multiplexing type (cdm-Type) and an RRC message.
[0227] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, the set of antenna port numbers to be measured may be selected or determined according to downlink control information.
[0228] Optionally, the downlink control information includes an X-bit port number indicator. Based on the code division multiplexing type (cdm-Type) and RRC configuration, the resource pools are {32, 24, 16, 8, 4, 2}. For example, if X = 8 bits, the LSB to MSB bits correspond to the antenna port numbers p1, p2, p4, p8, p12, p16, p24, and p32, respectively. For example, bits 00101110 indicate that the number of CSI reference signal ports to be measured is 16, 8, 4, and 2, respectively.
[0229] Optionally, the downlink control information includes Y bits indicating the maximum number of ports. Each Y-bit code point corresponds to an index in {p32, p24, p16, p12, p8, p4, p2, p1}. Taking Y = 3 bits as an example, 000 corresponds to a maximum number of ports of p1, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 1. 001 corresponds to a maximum number of ports of p2, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 2. 010 corresponds to a maximum number of ports of p4, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 4. And so on. If the resource pool for the number of antenna ports to be measured is {p32, p24, p16, p8, p4, p2}, and the "maximum number of ports" bits in the DCI are 011, then the number of ports to be measured is 8, 4, and 2.
[0230] This embodiment, through the above scheme, specifically configures the time domain and frequency domain resources of the channel state information reference signal of all possible ports in the RRC message, and indicates the port set of the channel state information reference signal that currently needs to be measured through DCI, thereby further improving the flexibility of dynamically adjusting the number of ports of the channel state information reference signal.
[0231] Seventh embodiment
[0232] Based on any of the above embodiments of the present application, this embodiment further discloses a processing method.
[0233] Optionally, channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource set identifiers, for example, the non-zero power channel state information reference signal resource set identifier corresponding to 32 ports is 1, the non-zero power channel state information reference signal resource set identifier corresponding to 24 ports is 3, and so on.
[0234] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource identifiers, at least one of the high-level parameters of the channel state information reference signals with each number of ports, the first symbol of the first time domain (firstOFDMSymbolInTimeDomain), the first symbol of the second time domain (firstOFDMSymbolInTimeDomain 2), density (density), code division multiplexing type (cdm-type) and frequency domain range (freqBand) are the same.
[0235] Optionally, when channel state information reference signals with different numbers of ports have different non-zero power channel state information reference signal resource set identifiers, the positions set to 1 in the high-level parameter frequencyDomainAllocation of the channel state information reference signal with each number of ports need to be a subset of the positions set to 1 in the high-level parameter frequencyDomainAllocation of the maximum number of ports in the resource pool.
[0236] Optionally, if cdm-Type = fd-CDM2 and the resource pool partitioning method in Table 1 is used, the resource pool to which the number of antenna ports to be measured belongs is {p32, p24, p16, p8, p4, p2}. Optionally, since the position set to 1 in the higher-layer parameter frequencyDomainAllocation of the channel state information reference signal for each port is a subset of the higher-layer parameter frequencyDomainAllocation of the channel state information reference signal for the maximum number of ports in the resource pool, if the maximum number of ports in the resource pool is 32 and frequencyDomainAllocation for 32 ports = 011110, the higher-layer parameter frequencyDomainAllocation for each number of ports must be configured within the bit limit specified in Table 7.4.1.5.3-1 of 38.211 and the position set to 1 in frequencyDomainAllocation for 32 ports. Optionally, the number of antenna ports of the channel state information reference signal to be measured is 24, 16, and 8; and the non-zero power channel state information reference signal resource set identifier of the 24-port channel state information reference signal obtained according to the RRC message is 3, the non-zero power channel state information reference signal resource set identifier of the 16-port channel state information reference signal is 5, and the non-zero power channel state information reference signal resource set identifier of the 8-port channel state information reference signal is 6, then the value of frequencyDomainAllocation of the 24-port channel state information reference signal can be 010110, the value of frequencyDomainAllocation of the 16-port channel state information reference signal can be 011110, and the value of frequencyDomainAllocation of the 8-port channel state information reference signal can be 010010. According to Table 7.4.1.5.3-1 of 38.211 and the frequency domain mapping rules, the time-frequency domain resources occupied by the 24-port in one RB are shown in Figure 13; according to Table 38.211 According to 7.4.1.5.3-1 and the frequency domain mapping rules, the time-frequency domain resources occupied by 16 ports in one RB are shown in Figure 14; the time-frequency domain resources occupied by 8 ports in one RB are shown in Figure 15.Optionally, taking port 24 as an example, the higher-layer parameter frequencyDomainAllocation of the channel state information reference signal of port 24 may also be 010110, 011100, or 001110, etc. That is, according to Table 7.4.1.5.3-1 of 38.211, the channel state information reference signal of port 24 only needs to select the three bit positions set to 1 in the higher-layer parameter frequencyDomainAllocation of port 32.
[0237] This embodiment uses the above-mentioned scheme, specifically by having different non-zero power channel state information reference signal resource set identifiers for channel state information reference signals with different numbers of ports, to achieve multiplexing of time domain and frequency domain resources of channel state information reference signals with different numbers of ports, thereby reducing interference between time domain and frequency domain resources of channel state information reference signals with different numbers of ports; and / or, it can improve the flexibility of time domain and frequency domain resource mapping of channel state information reference signals with different numbers of ports.
[0238] Eighth embodiment
[0239] Based on any of the above embodiments of the present application, this embodiment further discloses a processing method.
[0240] Optionally, when channel state information reference signals with different numbers of ports have different non-zero-power channel state information reference signal resource set identifiers, the number of antenna ports to be measured may be directly specified by an RRC message.
[0241] Optionally, if cdm-Type = fd-CDM2 and the resource pool partitioning method in Table 1 is used, the resource pool to which the number of antenna ports to be measured belongs is {p32, p24, p16, p8, p4, p2}. If the RRC message only configures the non-zero-power channel state information reference signal resource set identifier 3 for the 4-port channel state information reference signal, the non-zero-power channel state information reference signal resource set identifier 5 for the 16-port channel state information reference signal, and the non-zero-power channel state information reference signal resource set identifier 6 for the 8-port channel state information reference signal, then the number of antenna ports to be measured is 24 ports, 16 ports, and 8 ports.
[0242] Optionally, when the non-zero power channel state information reference signal resource set identifiers of the channel state information reference signals of different ports are used, the number of antenna ports to be measured can be determined by the downlink control information, and the RRC message includes the time-frequency resource configuration information of the channel state information reference signals of all antenna ports in the resource pool.
[0243] Optionally, the code division multiplexing type (cdm-Type) = fd-CDM2. If the resource pool partitioning method in Table 1 is used and the resource pool is {p32, p24, p16, p8, p4, p2}, then the RRC message includes the time-frequency resource configuration information of the channel state information reference signal for all antenna ports in the resource pool. Optionally, since each antenna port number has a non-zero power channel state information reference signal resource set identifier, the non-zero power channel state information reference signal resource set identifier for each antenna port number can be as shown in Table 4:
[0244] Table 4. Second example table of RRC configuration of channel state information reference signals of different ports
[0245] Optionally, Table 4 is only an example of different numbers of antenna ports having different non-zero power channel state information reference signal resource set identifiers. The resource set identifiers of channel state information reference signals with different numbers of ports can be configured by RRC according to specific circumstances.
[0246] Optionally, when channel state information reference signals with different numbers of ports have different non-zero-power channel state information reference signal resource set identifiers, the set of antenna port numbers to be measured may be selected or determined according to downlink control information.
[0247] Optionally, the resource pool to which each port number belongs is determined according to a code division multiplexing type (cdm-Type) and an RRC message.
[0248] Optionally, the downlink control information includes an X-bit port number indicator. Based on the code division multiplexing type (cdm-Type) and RRC configuration, the resource pools are {p32, p24, p16, p8, p4, p2}. For example, if X = 8 bits, from the LSB bit to the MSB bit, they correspond to the number of antenna ports p1, p2, p4, p8, p12, p16, p24, and p32, respectively. For example, bits 00101110 indicate that the number of CSI reference signal ports to be measured is 16, 8, 4, and 2, respectively.
[0249] Optionally, the downlink control information includes Y bits indicating the maximum number of ports. Each Y-bit code point corresponds to an index in {p32, p24, p16, p12, p8, p4, p2, p1}. Taking Y = 3 bits as an example, 000 corresponds to a maximum number of ports of p1, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 1. 001 corresponds to a maximum number of ports of p2, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 2. 010 corresponds to a maximum number of ports of p4, i.e., the maximum number of antenna ports in the set of antenna ports to be measured is 4. And so on. If the resource pool for the number of antenna ports to be measured is {p32, p24, p16, p8, p4, p2}, and the "maximum number of ports" bits in the DCI are 011, then the number of ports to be measured is 8, 4, and 2.
[0250] This embodiment uses the above scheme, specifically by configuring the time domain resources and / or frequency domain resources of the channel state information reference signal of all possible ports at one time in the RRC message, and indicating the port set of the channel state information reference signal that currently needs to be measured through DCI, thereby further improving the flexibility of dynamically adjusting the number of ports of the channel state information reference signal.
