Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, and device. Background Art

[0002] The performance of large-scale MIMO (Multiple Input Multiple Output) depends on the number of antennas. Larger antenna arrays and more radio frequency links can bring better performance. Currently, a CSI-RS (Channel State Information-Reference Signal) resource supports a maximum of only 32 antenna ports. As the number of antenna elements in the antenna array increases, CSI-RS resources supporting more than 32 ports will be required for channel measurement. Considering expanding the number of antenna ports of a CSI-RS resource to more than 32 ports will be beneficial to system performance.

[0835] First, the content related to the solution provided in the embodiments of the present application will be introduced below.

[0836] Currently, the number of ports supported by the NR (New Radio) system is: 1, 2, 4, 8, 12, 16, 24, 32.

[0837] Among them, NR defines three CDM (Code Division Multiplexing) patterns, namely CDM-2, CDM-4, and CDM-8. Specifically, as shown in Figure 2 where FD represents frequency division; TD represents time division.

[0838] Specifically, the Resource Elements (REs) occupied by a CDM pattern form a CDM group. Each CDM group can include 2, 4, or 8 ports. In this way, multiple ports of CSI-RS can be distributed into multiple CDM groups with the same pattern, that is, the port distribution of CSI-RS can be determined through CDM group aggregation. NR supports a variety of flexible aggregation schemes. For the same port configuration, multiple CDM group aggregation schemes are supported. NR flexibly supports CSI-RS with 2 to 32 ports by using CDM group aggregation of the three CDM patterns of CDM-2, CDM-4, and CDM-8. The following table shows the configuration relationship between the number of CSI-RS ports and CDM combinations:

[0839]

[0840] Among them, RE / RB / port in the above table means dividing all occupied REs by the number of RBs corresponding to all REs, and then dividing by the total number of ports port (i.e., X).

[0841] Based on the above, embodiments of the present application provide an information transmission method, apparatus, and device to solve the problem in the prior art that it is impossible to implement the transmission of relevant information corresponding to a CSI-RS pattern with more than 32 ports. Among them, the method, apparatus, and device are based on the same inventive concept. Since the principles of the method, apparatus, and device for solving problems are similar, the implementation of the method, apparatus, and device can be referred to each other, and the repeated parts will not be elaborated.

[0842] The information transmission method provided by the embodiments of the present application is applied to a network device, such as Figure 3 shown, and includes:

[0843] Step 31: Determine target configuration information according to the selected channel state information reference signal CSI-RS pattern;

[0844] Among them, the selected CSI-RS pattern can be determined by the network device according to the number of antenna ports, CSI-RS transmission power requirement information, and the resource occupancy of signals such as the synchronization signal block SSB signal, demodulation reference signal DMRS, and physical downlink control channel PDCCH signal, but it is not limited thereto. The target configuration information can include any information used to assist the terminal in determining the CSI-RS pattern, such as the number of antenna ports, etc.

[0845] Step 32: Send the target configuration information to the terminal; wherein, the number of ports corresponding to the CSI-RS is greater than 32; the CSI-RS pattern is a pattern within one or two time slots in the time domain and within one or two physical resource blocks PRBs in the frequency domain; the CSI-RS pattern is aggregated by at least one code division multiplexing CDM type pattern through time division multiplexing TDM and / or frequency division multiplexing FDM; the CDM type includes at least one of the following: 16-port pattern type, 32-port pattern type, 8-port pattern type, 4-port pattern type, and 2-port pattern type; the target configuration information includes: the number of antenna ports, density information, CDM type information, CDM group frequency domain position indication information, and CDM group time domain position indication information; one CDM group corresponds to one CDM type.

[0846] Among them, after step 32, the network device may send CSI-RS based on the selected CSI-RS pattern; the terminal may perform CSI-RS reception measurement based on the CSI-RS pattern determined according to the target configuration information; but this is not limited thereto. Regarding "sending the target configuration information to the terminal", it may be sent periodically or semi-persistently or aperiodically; the sub-information included in the target configuration information is sent together; the density information may specifically be 1 or 0.5, etc.; the CDM type information is used to indicate at least one of the 16-port pattern type, 32-port pattern type, 8-port pattern type, 4-port pattern type, and 2-port pattern type; the resource elements (REs) occupied by a pattern of one CDM type form a CDM group.

[0847] The information transmission method provided by the embodiments of this application determines the target configuration information according to the selected channel state information reference signal (CSI-RS) pattern; sends the target configuration information to the terminal; where the number of ports corresponding to the CSI-RS is greater than 32; the CSI-RS pattern is a pattern within one or two time slots in the time domain and within one or two physical resource blocks (PRBs) in the frequency domain; the CSI-RS pattern is obtained by aggregating at least one code division multiplexing (CDM) type pattern through time division multiplexing (TDM) and / or frequency division multiplexing (FDM); the CDM type includes at least one of the following: 16-port pattern type, 32-port pattern type, 8-port pattern type, 4-port pattern type, and 2-port pattern type; the target configuration information includes: the number of antenna ports, density information, CDM type information, CDM group frequency domain position indication information, and CDM group time domain position indication information; one CDM group corresponds to one CDM type; and it can support the implementation of relevant information transmission corresponding to a CSI-RS pattern with more than 32 ports.

[0848] Among them, determining the target configuration information according to the selected channel state information reference signal (CSI-RS) pattern includes: determining the target configuration information according to the pattern configuration information and the selected CSI-RS pattern; where the pattern configuration information includes: the number of antenna ports, density information, CDM type information, CDM group frequency domain position indication information, CDM group time domain position indication information, CDM group index, frequency domain index within the CDM group, and time domain index within the CDM group.

[0849] In this way, the target configuration information can be accurately obtained. Among them, the target configuration information can be partial information of the pattern configuration information. The pattern configuration information can be predefined, but it is not limited thereto. The pattern configuration information can be presented in the form of a table; the CDM group frequency-domain position indication information can indicate the starting position of the resources occupied by the CDM group in the frequency domain, etc.; the CDM group time-domain position indication information can indicate the starting position of the resources occupied by the CDM group in the time domain, etc.; the CDM group index can refer to the index of the CDM group in all CDM groups (i.e., the CDM group set) corresponding to the CSI-RS pattern. The numbering order of this index can correspond to the position numbering order in the position indication information combination (i.e., the combination formed by the CDM group frequency-domain position indication information and the CDM group time-domain position indication information). The position numbering order in this position indication information combination can be carried out in the way of increasing the frequency-domain number first and then increasing the time-domain number. For specific details, please refer to Among them, the CDM group index j corresponds to For example, when the CDM group index j takes the value 0, it corresponds to in (k 0 , l 0 ); the frequency-domain index inside the CDM group refers to the frequency-domain index inside the CDM group corresponding to each element in a CDM group, and the time-domain index inside the CDM group refers to the time-domain index inside the CDM group corresponding to each element in a CDM group.

[0850] In the embodiments of the present application, the 16-port pattern types include: cdm16-FD4-TD4 pattern type and / or cdm16-FD2-TD8 pattern type; and / or, the 32-port pattern types include cdm32-FD4-TD8 pattern type; and / or, the 8-port pattern types include cdm8-FD2-TD4 pattern type; and / or, the 4-port pattern types include cdm4-FD2-TD2 pattern type; and / or, the 2-port pattern types include fd-CDM2 pattern type; where (1) the cdm16-FD4-TD4 pattern type means that the pattern occupies 4 consecutive resource elements (REs) in the frequency domain and 4 consecutive REs in the time domain; each port occupies 16 REs, and each port corresponds to a different orthogonal cover code (OCC); (2) the cdm16-FD2-TD8 pattern type means that the pattern occupies 2 consecutive REs in the frequency domain and 8 consecutive REs in the time domain; each port occupies 16 REs, and each port corresponds to a different OCC; (3) the cdm32-FD4-TD8 pattern type means that the pattern occupies 4 consecutive REs in the frequency domain and 8 consecutive REs in the time domain; each port occupies 32 REs, and each port corresponds to a different OCC; (4) the cdm8-FD2-TD4 pattern type means that the pattern occupies 2 consecutive REs in the frequency domain and 4 consecutive REs in the time domain; each port occupies 8 REs, and each port corresponds to a different OCC; (5) the cdm4-FD2-TD2 pattern type means that the pattern occupies 2 consecutive REs in the frequency domain and 2 consecutive REs in the time domain; each port occupies 4 REs, and each port corresponds to a different OCC; (6) the fd-CDM2 pattern type means that the pattern occupies 2 consecutive REs in the frequency domain and 1 consecutive RE in the time domain; each port occupies 2 REs, and each port corresponds to a different OCC.

[0851] In this way, the specific information of each port pattern type can be clarified. The above port pattern types are only examples and are not limited thereto. For example, the 16-port pattern type can also include the cdm16-FD8-TD2 pattern type, etc.; "different orthogonal cover codes OCC" means that at least part of the content included in the OCC is different.

[0852] Wherein, when the CSI-RS pattern is aggregated from the cdm16-FD4-TD4 pattern type and / or the cdm32-FD4-TD8 pattern type, the position of the CDM group included in the CSI-RS pattern within a PRB is indicated by a high-level parameter through a 3-bit bitmap, and the bitmap is composed of setting value b 2 、setting value b 1 and setting value b 0 constitutes, and the starting position k i-1= 4f(i), where f(i) is the subscript index x of the i-th set value of 1 in the bitmap, and i ∈ {1, 2, 3}. x of the b

[0853] In this way, the frequency-domain indication of the CSI-RS pattern in the above case can be specifically implemented. For example, if the 3-bit bitmap is 110, starting from the least significant bit (i.e., the rightmost 0) in the bitmap, the first (i = 1) set value of 1 is b 1 (x = 1), so f(1) = x = 1. Therefore, when i = 1, k 0 = 4 × f(1) = 4 × 1. Similarly, when i = 2, k 1 = 4 × f(2) = 4 × 2. Among them, the high-layer parameter can be radio resource control (RRC) information, but is not limited thereto.

[0854] In the embodiments of the present application, the CDM group frequency-domain position indication information is indicated by at least one of the following methods: Method 1, one CSI-RS pattern corresponds to only one CDM group frequency-domain position indication information, and the subcarrier positions occupied by the CSI-RS pattern in a PRB are indicated by high-layer parameters through a set of bitmaps, and all PRBs occupied by the CSI-RS pattern have the same frequency-domain position; Method 2, one CSI-RS pattern corresponds to two CDM group frequency-domain position indication information, and the two CDM group frequency-domain position indication information are indicated by high-layer parameters through two sets of bitmaps, and each set of bitmaps respectively indicates the subcarrier positions occupied by the CSI-RS pattern in a PRB.

[0855] In this way, the CDM group frequency-domain position indication information can be indicated in multiple ways. Among them, in Method 2, "the two CDM group frequency-domain position indication information are indicated by high-layer parameters through two sets of bitmaps, and each set of bitmaps respectively indicates the subcarrier positions occupied by the CSI-RS pattern in a PRB" can be understood as: the subcarrier positions occupied by the first pattern in two consecutive PRBs are indicated by high-layer parameters through two sets of bitmaps, and different PRBs correspond to different bitmaps (for example, the subcarrier positions occupied by the first pattern in the frequency domain corresponding to subcarrier indices 0-11 in PRB1 and the subcarrier positions corresponding to subcarrier indices 0-3 in PRB2; then the subcarrier indices 0-11 in PRB1 can be indicated by bits Figure 1 (for example, all the included values are 1), and the subcarrier indices 0-3 in PRB2 can be indicated by bits Figure 2 (for example, the lower 4 bits of the included values are all 1)), but is not limited thereto. Each CDM group frequency-domain position indication information can only include one high-layer parameter. Among them, the high-layer parameter can be radio resource control (RRC) information, but is not limited thereto.

[0856] Among them, the first method corresponds to at least one of the following settings: (1) Pre-define that the minimum frequency-domain resource occupied by all ports of the CSI-RS pattern is one or two consecutive PRBs; (2) Configure a first new parameter through a high-layer parameter to indicate that the minimum frequency-domain resource occupied by all ports of the CSI-RS pattern is one or two PRBs; (3) Determine that the minimum frequency-domain resource occupied by the CSI-RS pattern is X / (J×L) PRBs according to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information; the number of CDM groups J is obtained according to the CDM group frequency-domain position indication information and the CDM group time-domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, X / (J×L) PRBs are consecutive.

[0857] This can support the specific implementation of frequency-domain indication in combination with the first method above. For example, the first method above indicates that the subcarrier positions of the PRBs occupied in the frequency domain correspond to subcarrier indices 0 to 11. Combining the above setting (1), if the pre-defined minimum frequency-domain resource is one PRB, then the subcarrier positions of the CSI-RS pattern occupying PRB1 in the frequency domain correspond to subcarrier indices 0 to 11; if the pre-defined minimum frequency-domain resource is two PRBs, then the subcarrier positions of the CSI-RS pattern occupying PRB1 in the frequency domain correspond to subcarrier indices 0 to 11 and the subcarrier positions of the CSI-RS pattern occupying PRB2 in the frequency domain correspond to subcarrier indices 0 to 11; the above setting (2) is similar. In addition, the above setting (3) can support the implementation scheme in the case where the number of antenna ports X does not exist in the pattern configuration information. Such a situation is, for example: the network side configures a CSI-RS pattern with X = 64 ports (there is no configuration information for 64 ports in the pattern configuration information), but 32 ports can be placed in each corresponding PRB, and these 32 ports in each PRB are configured according to the pattern configuration information, which is not limited here. Among them, "the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information" may specifically include: the number of CDM groups J corresponding to the CDM group frequency-domain position indication information, the group size L of the CDM group corresponding to the CDM group type (information), and the number of antenna ports X included in the target configuration information, but is not limited thereto.

[0858] In the embodiments of the present application, the CDM group time-domain position indication information is indicated by at least one of the following methods: Method 1, one CSI-RS pattern corresponds to only one set of CDM group time-domain position indication information, and all time slots occupied by one CSI-RS pattern have the same time-domain position; Method 2, one CSI-RS pattern corresponds to two sets of CDM group time-domain position indication information, and each set of CDM group time-domain position indication information respectively indicates the orthogonal frequency division multiplexing (OFDM) symbol positions occupied by the CSI-RS pattern within one time slot.

[0859] In this way, the CDM group time-domain position indication information can be indicated in multiple ways. Among them, one set of CDM group time-domain position indication information may include 2 parameters, and each parameter represents an OFDM symbol position (for example, the starting position of the OFDM symbols occupied by the first pattern in time slot 1 corresponds to OFDM symbol indices 4 and 10, and the starting position of the OFDM symbols occupied by the first pattern in time slot 2 corresponds to OFDM symbol indices 2 and 8; then the OFDM symbol indices of time slot 1 can be indicated by l 0 = 4 and l 1 = 10, and the OFDM symbol indices of time slot 2 can be indicated by l 0 ' = 2 and l 1 ' = 8, but not limited thereto. Among them, the high-layer parameter may be radio resource control (RRC) information, but not limited thereto.

[0860] Among them, Method 1 (under the CDM group time-domain position indication information) corresponds to at least one of the following settings: (1) It is predefined that the minimum time-domain resource occupied by all ports of one CSI-RS pattern is one or two consecutive time slots; (2) A second new parameter is configured through a high-layer parameter to indicate that the minimum time-domain resource occupied by all ports of the CSI-RS pattern is one or two time slots; (3) According to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information, it is determined that the minimum time-domain resource occupied by the CSI-RS pattern is X / (J×L) time slots; the number of CDM groups J is obtained according to the CDM group frequency-domain position indication information and the CDM group time-domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, X / (J×L) time slots are consecutive.

[0861] This can support the specific implementation of time domain indication in combination with the corresponding Method 1. For example, in the above Method 1 indication (under the CDM group time domain position indication information), the starting positions of the OFDM symbols occupied in the time domain correspond to OFDM symbol indices 4 and 10. Combining the above setting (1), if the predefined minimum time domain resource is one time slot, then the starting positions of the OFDM symbols occupied by the CSI-RS pattern in the time domain correspond to OFDM symbol indices 4 and 10 of time slot 1; if the predefined minimum time domain resource is two time slots, then the starting positions of the OFDM symbols occupied by the CSI-RS pattern in the time domain correspond to OFDM symbol indices 4 and 10 of time slot 1 and the starting positions of the OFDM symbols occupied by time slot 2 correspond to OFDM symbol indices 4 and 10 of time slot 2; the above setting (2) is similar. In addition, the above setting (3) can support the implementation solution in the case where the number of antenna ports X does not exist in the pattern configuration information. Such a situation is, for example: the network side configures a CSI-RS pattern with X = 64 ports (there is no configuration information for 64 ports in the pattern configuration information), but 32 ports can be placed in each corresponding time slot, and these 32 ports in each time slot are configured according to the pattern configuration information, which is not limited here. Among them, "the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information" can specifically include: the number of CDM groups J corresponding to the CDM group time domain position indication information, the group size L of the CDM group corresponding to the CDM group type (information), and the number of antenna ports X included in the target configuration information, but is not limited thereto.

[0862] In the embodiment of the present application, when the number of ports corresponding to the CSI-RS is 48, the CSI-RS pattern is obtained by using at least one of the following: aggregating 3 patterns of the cdm16-FD4-TD4 pattern type by FDM; aggregating 3 patterns of the cdm16-FD2-TD8 pattern type by FDM; aggregating 24-port patterns of 2 cdm8-FD2-TD4 pattern types by FDM; aggregating 24-port patterns of 2 cdm8-FD2-TD4 pattern types by TDM; aggregating 24-port patterns of 2 cdm4-FD2-TD2 pattern types by FDM; aggregating 24-port patterns of 2 cdm4-FD2-TD2 pattern types by TDM; aggregating 24-port patterns of 2 fd-CDM2 pattern types by FDM; aggregating 24-port patterns of 2 fd-CDM2 pattern types by TDM.

[0863] This can clarify the manner of obtaining the CSI-RS pattern corresponding to 48 ports. Among them, for the case of "aggregating 24-port patterns of 2 cdm4-FD2-TD2 pattern types through the TDM method", optionally, all the OFDM symbols occupied in the time domain must be continuous; for the case of "aggregating 24-port patterns of 2 fd-CDM2 pattern types through the TDM method", optionally, all the OFDM symbols occupied in the time domain must be continuous; this is not limited herein. Among them, the 24-port pattern of the cdm8-FD2-TD4 pattern type can specifically be obtained by aggregating 3 patterns of the cdm8-FD2-TD4 pattern type through the FDM method; the 24-port pattern of the cdm4-FD2-TD2 pattern type can specifically be obtained by aggregating 6 patterns of the cdm4-FD2-TD2 pattern type through the TDM method and / or the FDM method; the 24-port pattern of the fd-CDM2 pattern type can specifically be obtained by aggregating 12 patterns of the fd-CDM2 pattern type through the TDM method and / or the FDM method, but this is not limited thereto.

[0864] Among them, when the number of ports corresponding to the CSI-RS is 64, the CSI-RS pattern is obtained by using at least one of the following: aggregating 4 patterns of the cdm16-FD4-TD4 pattern type through the FDM method; aggregating 4 patterns of the cdm16-FD2-TD8 pattern type through the FDM method; aggregating 2 patterns of the cdm32-FD4-TD8 pattern type through the FDM method; aggregating 2 32-port patterns of the cdm8-FD2-TD4 pattern type through the TDM method; aggregating 2 32-port patterns of the cdm4-FD2-TD2 pattern type through the TDM method; aggregating 2 32-port patterns of the fd-CDM2 pattern type through the TDM method.

[0865] This can clarify the manner of obtaining the CSI-RS pattern corresponding to port 64. Among them, for the case of "aggregating 32-port patterns of 2 cdm4-FD2-TD2 pattern types through the TDM method", optionally, all OFDM symbols occupied in the time domain must be continuous; for the case of "aggregating 32-port patterns of 2 fd-CDM2 pattern types through the TDM method", optionally, all OFDM symbols occupied in the time domain must be continuous; this is not limited herein.

[0878] The embodiment of this application also provides an information transmission method, which is applied to a terminal, such as Figure 4 shown, including:

[0879] Step 41: Receive the target configuration information sent by the network device;

[0883] Among them, the determining the selected CSI-RS pattern according to the target configuration information includes: determining the selected CSI-RS pattern according to the pattern configuration information and the target configuration information, where the pattern configuration information includes: the number of antenna ports, density information, CDM type information, CDM group frequency domain position indication information, CDM group time domain position indication information, CDM group index, frequency domain index inside the CDM group, and time domain index inside the CDM group.

[0884] In this way, the target configuration information can be accurately obtained. Among them, the target configuration information can be partial information of the pattern configuration information, and the pattern configuration information can be predefined, but not limited thereto.

[0885] In the embodiment of the present application, the 16-port pattern type includes: cdm16-FD4-TD4 pattern type and / or cdm16-FD2-TD8 pattern type; and / or, the 32-port pattern type includes cdm32-FD4-TD8 pattern type; and / or, the 8-port pattern type includes cdm8-FD2-TD4 pattern type; and / or, the 4-port pattern type includes cdm4-FD2-TD2 pattern type; and / or, the 2-port pattern type includes fd-CDM2 pattern type; wherein, (1) the cdm16-FD4-TD4 pattern type indicates that the pattern occupies 4 consecutive resource elements RE in the frequency domain and 4 consecutive RE in the time domain; each port occupies 16 REs, and each port corresponds to a different orthogonal cover code OCC; (2) the cdm16-FD2-TD8 pattern type indicates that the pattern occupies 2 consecutive REs in the frequency domain and 8 consecutive REs in the time domain. RE; each port occupies 16 REs, and each port corresponds to a different OCC; (3) the cdm32-FD4-TD8 pattern type indicates that the pattern occupies 4 consecutive REs in the frequency domain and 8 consecutive REs in the time domain; each port occupies 32 REs, and each port corresponds to a different OCC; (4) the cdm8-FD2-TD4 pattern type indicates that the pattern occupies 2 consecutive REs in the frequency domain and 4 consecutive REs in the time domain; each port occupies 8 REs, and each port corresponds to a different OCC; (5) the cdm4-FD2-TD2 pattern type indicates that the pattern occupies 2 consecutive REs in the frequency domain and 2 consecutive REs in the time domain; each port occupies 4 REs, and each port corresponds to a different OCC; (6) the fd-CDM2 pattern type indicates that the pattern occupies 2 consecutive REs in the frequency domain and 1 consecutive RE in the time domain; each port occupies 2 REs, and each port corresponds to a different OCC.

[0886] Wherein, when the CSI-RS pattern is obtained by aggregating patterns of cdm16-FD4-TD4 pattern type and / or cdm32-FD4-TD8 pattern type, the position of the CDM group contained in the CSI-RS pattern within a PRB is indicated by a high-level parameter through a 3-bit bitmap, and the bitmap is set by a value b 2 、Set value b 1 and set value b 0 Composition, the starting position k of the CDM group in the frequency domain i-1 =4f(i), where f(i) is the i-th b set to 1 in the bitmap x The subscript index x, i∈{1,2,3}.

[0887] This can specifically implement the frequency-domain indication of the CSI-RS pattern in the above case. Specifically, for example, if the 3-bit bitmap is 110, starting from the least significant bit (i.e., the rightmost 0) in the bitmap, the first (i = 1) bit set to 1 is b 1 (x = 1), so f(1) = x = 1. Therefore, when i = 1, k 0 = 4 × f(1) = 4 × 1. Similarly, when i = 2, k 1 = 4 × f(2) = 4 × 2.

[0888] In the embodiments of the present application, the CDM group frequency-domain position indication information is indicated by at least one of the following methods: Method 1, one CSI-RS pattern corresponds to only one CDM group frequency-domain position indication information, and the subcarrier positions occupied by the CSI-RS pattern in a PRB are indicated by a set of bitmaps by high-layer parameters, and all PRBs occupied by the CSI-RS pattern have the same frequency-domain position; Method 2, one CSI-RS pattern corresponds to two CDM group frequency-domain position indication information, and the two CDM group frequency-domain position indication information are indicated by high-layer parameters through two sets of bitmaps, and each set of bitmaps respectively indicates the subcarrier positions occupied by the CSI-RS pattern in a PRB.

[0889] This can indicate the CDM group frequency-domain position indication information in multiple ways. Among them, in Method 2, "the two CDM group frequency-domain position indication information are indicated by high-layer parameters through two sets of bitmaps, and each set of bitmaps respectively indicates the subcarrier positions occupied by the CSI-RS pattern in a PRB" can be understood as: the subcarrier positions occupied by the first pattern in two consecutive PRBs are indicated by high-layer parameters through two sets of bitmaps, and different PRBs correspond to different bitmaps, but it is not limited thereto. Each CDM group frequency-domain position indication information may only include one high-layer parameter.

[0890] Among them, the first method corresponds to at least one of the following settings: (1) Pre-define that the minimum frequency-domain resource occupied by all ports of the CSI-RS pattern is one or two consecutive PRBs; (2) Configure a first new parameter through a high-layer parameter to indicate that the minimum frequency-domain resource occupied by all ports of the CSI-RS pattern is one or two PRBs; (3) Determine that the minimum frequency-domain resource occupied by the CSI-RS pattern is X / (J×L) PRBs according to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information; the number of CDM groups J is obtained according to the CDM group frequency-domain position indication information and the CDM group time-domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, X / (J×L) PRBs are consecutive.

[0891] This can support the realization of frequency-domain indication in combination with the first method above. The above setting (3) can support the implementation of the solution when the number of antenna ports X does not exist in the pattern configuration information. For example, the network side configures a CSI-RS pattern with X = 64 ports (there is no configuration information for 64 ports in the pattern configuration information), but 32 ports can be placed in each corresponding PRB, and these 32 ports in each PRB are configured according to the pattern configuration information, which is not limited here. Among them, "the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information" can specifically include: the number of CDM groups J corresponding to the CDM group frequency-domain position indication information, the group size L of the CDM group corresponding to the CDM group type (information), and the number of antenna ports X included in the target configuration information, but is not limited thereto.

[0892] In the embodiments of the present application, the CDM group time-domain position indication information is indicated by at least one of the following methods: Method 1, one CSI-RS pattern corresponds to only one set of CDM group time-domain position indication information, and all time slots occupied by one CSI-RS pattern have the same time-domain position; Method 2, one CSI-RS pattern corresponds to two sets of CDM group time-domain position indication information, and each set of CDM group time-domain position indication information respectively indicates the OFDM symbol positions occupied by the CSI-RS pattern in one time slot.

[0893] This can indicate the CDM group time-domain position indication information in multiple ways. Among them, one set of CDM group time-domain position indication information may include 2 parameters, and each parameter represents an OFDM symbol position, but is not limited thereto.

[0894] Among them, the first method corresponds to at least one of the following settings: (1) Pre-define that the minimum time-domain resource occupied by all ports of the CSI-RS pattern is one or two consecutive time slots; (2) Configure a second new parameter through a high-layer parameter to indicate that the minimum time-domain resource occupied by all ports of the CSI-RS pattern is one or two time slots; (3) Determine that the minimum time-domain resource occupied by the CSI-RS pattern is X / (J×L) time slots according to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information; the number of CDM groups J is obtained according to the CDM group frequency-domain position indication information and the CDM group time-domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, the X / (J×L) time slots are consecutive.

[0895] This can support the specific implementation of time-domain indication in combination with the corresponding first method. The above setting (3) can support the implementation scheme when the number of antenna ports X does not exist in the pattern configuration information. For example, the network side configures a CSI-RS pattern with X = 64 ports (there is no configuration information for 64 ports in the pattern configuration information), but 32 ports can be placed in each corresponding time slot, and these 32 ports in each time slot are configured according to the pattern configuration information, which is not limited here. Among them, "the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information" can specifically include: the number of CDM groups J corresponding to the CDM group time-domain position indication information, the group size L of the CDM group corresponding to the CDM group type (information), and the number of antenna ports X included in the target configuration information, but is not limited thereto.

[0896] In the embodiment of the present application, when the number of ports corresponding to the CSI-RS is 48, the CSI-RS pattern is obtained by using at least one of the following: aggregating 3 patterns of the cdm16-FD4-TD4 pattern type through the FDM method; aggregating 3 patterns of the cdm16-FD2-TD8 pattern type through the FDM method; aggregating 2 24-port patterns of the cdm8-FD2-TD4 pattern type through the FDM method; aggregating 2 24-port patterns of the cdm8-FD2-TD4 pattern type through the TDM method; aggregating 2 24-port patterns of the cdm4-FD2-TD2 pattern type through the FDM method; aggregating 2 24-port patterns of the cdm4-FD2-TD2 pattern type through the TDM method; aggregating 2 24-port patterns of the fd-CDM2 pattern type through the FDM method; aggregating 2 24-port patterns of the fd-CDM2 pattern type through the TDM method.

[0897] This can clarify the obtaining method of the CSI-RS pattern corresponding to the 48 ports. Among them, for the case of "aggregating 24-port patterns of 2 cdm4-FD2-TD2 pattern types through the TDM method", optionally, all the OFDM symbols occupied in the time domain must be continuous; for the case of "aggregating 24-port patterns of 2 fd-CDM2 pattern types through the TDM method", optionally, all the OFDM symbols occupied in the time domain must be continuous; no limitation is made here. Among them, the 24-port pattern of the cdm8-FD2-TD4 pattern type can specifically be obtained by aggregating 3 patterns of the cdm8-FD2-TD4 pattern type through the FDM method; the 24-port pattern of the cdm4-FD2-TD2 pattern type can specifically be obtained by aggregating 6 patterns of the cdm4-FD2-TD2 pattern type through the TDM method and / or the FDM method; the 24-port pattern of the fd-CDM2 pattern type can specifically be obtained by aggregating 12 patterns of the fd-CDM2 pattern type through the TDM method and / or the FDM method, but not limited thereto.

[0899] This can clarify the obtaining method of the CSI-RS pattern corresponding to port 64. Among them, for the case of "aggregating 32-port patterns of 2 cdm4-FD2-TD2 pattern types through the TDM method", optionally, all OFDM symbols occupied in the time domain must be continuous; for the case of "aggregating 32-port patterns of 2 fd-CDM2 pattern types through the TDM method", optionally, all OFDM symbols occupied in the time domain must be continuous; this is not limited herein. Among them, the 32-port pattern of the cdm8-FD2-TD4 pattern type can specifically be obtained by aggregating 4 patterns of the cdm8-FD2-TD4 pattern type through the FDM method; the 32-port pattern of the cdm4-FD2-TD2 pattern type can specifically be obtained by aggregating 8 patterns of the cdm4-FD2-TD2 pattern type through the TDM method and / or the FDM method; the 32-port pattern of the fd-CDM2 pattern type can specifically be obtained by aggregating 16 patterns of the fd-CDM2 pattern type through the TDM method and / or the FDM method, but not limited thereto.

[0900] In the embodiment of the present application, when the number of ports corresponding to the CSI-RS is 96, the CSI-RS pattern is obtained by using at least one of the following: aggregating 6 patterns of the cdm16-FD2-TD8 pattern type through the FDM method; aggregating 6 patterns of the cdm16-FD4-TD4 pattern type through the FDM method; aggregating 6 patterns of the cdm16-FD4-TD4 pattern type through the FDM and TDM methods; aggregating 3 patterns of the cdm32-FD4-TD8 pattern type through the FDM method; aggregating 2 48-port patterns of the cdm8-FD2-TD4 pattern type through the FDM or TDM method; aggregating 4 24-port patterns of the cdm8-FD2-TD4 pattern type through the FDM and TDM methods; aggregating 2 48-port patterns of the cdm4-FD2-TD2 pattern type through the FDM or TDM method; aggregating 4 24-port patterns of the cdm4-FD2-TD2 pattern type through the FDM and TDM methods; aggregating 2 48-port patterns of the fd-CDM2 pattern type through the FDM or TDM method; aggregating 4 24-port patterns of the fd-CDM2 pattern type through the FDM and TDM methods.

[0901] This can clarify the obtaining method of the CSI-RS pattern corresponding to 96 ports. Among them, for the case of "aggregating 48-port patterns of 2 cdm4-FD2-TD2 pattern types through FDM or TDM", and / or, "aggregating 24-port patterns of 4 cdm4-FD2-TD2 pattern types through FDM and TDM", and / or, "aggregating 48-port patterns of 2 fd-CDM2 pattern types through FDM or TDM", and / or, "aggregating 24-port patterns of 4 fd-CDM2 pattern types through FDM and TDM", optionally, all OFDM symbols occupied in the time domain must be continuous; this is not limited here.

[0902] Among them, when the number of ports corresponding to the CSI-RS is 128, the CSI-RS pattern is obtained by using at least one of the following: aggregating patterns of 4 cdm32-FD4-TD8 pattern types through FDM; aggregating patterns of 8 cdm16-FD4-TD4 pattern types through FDM and TDM; aggregating 32-port patterns of 4 cdm8-FD2-TD4 pattern types through FDM and TDM; aggregating 32-port patterns of 4 cdm8-FD2-TD4 pattern types through TDM.

[0903] This can clarify the obtaining method of the CSI-RS pattern corresponding to 128 ports. Among them, "aggregating through FDM" can be specifically understood as multiplexing in the frequency domain; "aggregating through FDM and TDM" can be specifically understood as multiplexing in both the frequency domain and the time domain; "aggregating through TDM" can be specifically understood as multiplexing in the time domain, but not limited thereto.

[0911] In this way, the combinations of FD-4OCC and TD-8OCC can be clarified. The index number order of the above combinations of each FD-4OCC and TD-8OCC can be arranged arbitrarily and is not limited here.

[0912] It should be noted here that the above solutions on the network device side and the terminal side can be referred to each other, and the repeated parts will not be elaborated.

[0913] Next, an example is given to illustrate the information transmission method provided in the embodiments of the present application.

[0914] In view of the above technical problems, the embodiments of the present application provide an information transmission method, which can be specifically implemented as a transmission scheme of CSI-RS, involving:

[0915] (1) The network side selects a CSI-RS pattern from the CSI-RS pattern set (corresponding to the above selected CSI-RS pattern). The network side sends the configuration information of the selected CSI-RS pattern (corresponding to the above target configuration information) to the terminal side.

[0916] (2) The terminal side receives the configuration information of the CSI-RS pattern, and determines the CSI-RS pattern according to the configuration information (corresponding to receiving the target configuration information sent by the network device above; according to the target configuration information, determining the selected CSI-RS pattern).

[0917] Among them, the CSI-RS pattern set and configuration information with more than 32 ports can be predefined, and the following is a specific introduction to the relevant content part.

[0918] Part 1, a CSI-RS with more than 32 ports, the pattern within one slot or two slots in the time domain and one PRB or two PRBs in the frequency domain (corresponding to the above CSI-RS pattern being within one or two time slots in the time domain and within one or two physical resource blocks PRBs in the frequency domain), is aggregated by at least one fd-CDM2 and / or cdm4-FD2-TD2 and / or cdm8-FD2-TD4 and / or cdm16-FD4-TD4 and / or cdm16-FD2-TD8 and / or cdm32-FD4-TD8 pattern, through the way of TDM and / or FDM (corresponding to the above CSI-RS pattern being aggregated by at least one code division multiplexing CDM type pattern through the way of time division multiplexing TDM and / or frequency division multiplexing FDM; the CDM type includes at least one of the following: 16-port pattern type, 32-port pattern type, 8-port pattern type, 4-port pattern type, and 2-port pattern type). Among them, different CDM types can be applied to different scenarios respectively. For example, FD2 can be selected for scenarios sensitive to frequency domain selectivity, and TD4 can be selected for scenarios sensitive to time domain selectivity, but it is not limited to this.

[0919] Among them, the explanations of each CDM type are as follows:

[0920] cdm16-FD4-TD4 means that it occupies 4 consecutive REs in the frequency domain and 4 consecutive REs in the time domain (corresponding to the above cdm16-FD4-TD4 pattern type, indicating that the pattern occupies 4 consecutive resource elements REs in the frequency domain and 4 consecutive REs in the time domain). 16 ports use the CDM method based on FD-4OCC+TD-4OCC to occupy the same RE position for transmission, that is, each port occupies 16 REs, and different OCCs are used to distinguish 16 ports (corresponding to each port occupying 16 REs, and each port corresponds to a different orthogonal cover code OCC).

[0921] cdm16-FD2-TD8 means that it occupies 2 consecutive REs in the frequency domain and 8 consecutive REs in the time domain (corresponding to the above cdm16-FD2-TD8 pattern type, indicating that the pattern occupies 2 consecutive REs in the frequency domain and 8 consecutive REs in the time domain). 16 ports use the CDM method based on FD-2OCC+TD-8OCC to occupy the same RE position for transmission, that is, each port occupies 16 REs, and different OCCs are used to distinguish 16 ports (corresponding to each port occupying 16 REs, and each port corresponds to a different OCC).

[0922] cdm32-FD4-TD8 means that it occupies 4 consecutive REs in the frequency domain and 8 consecutive REs in the time domain (corresponding to the above cdm32-FD4-TD8 pattern type, indicating that the pattern occupies 4 consecutive REs in the frequency domain and 8 consecutive REs in the time domain). 32 ports use the CDM method based on FD-4OCC+TD-8OCC to occupy the same RE positions for transmission, that is, each port occupies 32 REs, and different OCCs are used to distinguish 32 ports (corresponding to each port occupying 32 REs above, and each port corresponding to a different OCC).

[0923] cdm8-FD2-TD4 means that it occupies 2 consecutive REs in the frequency domain and 4 consecutive REs in the time domain (corresponding to the above cdm8-FD2-TD4 pattern type, indicating that the pattern occupies 2 consecutive REs in the frequency domain and 4 consecutive REs in the time domain). 8 ports use the CDM method based on FD-2OCC+TD-4OCC to occupy the same RE positions for transmission, that is, each port occupies 8 REs, and different OCCs are used to distinguish 8 ports (corresponding to each port occupying 8 REs above, and each port corresponding to a different OCC).

[0924] cdm4-FD2-TD2 means that it occupies 2 consecutive REs in the frequency domain and 2 consecutive REs in the time domain (corresponding to the above cdm4-FD2-TD2 pattern type, indicating that the pattern occupies 2 consecutive REs in the frequency domain and 2 consecutive REs in the time domain). 4 ports use the CDM method based on FD-2OCC+TD-2OCC to occupy the same RE positions for transmission, that is, each port occupies 4 REs, and different OCCs are used to distinguish 4 ports (corresponding to each port occupying 4 REs above, and each port corresponding to a different OCC).

[0925] fd-CDM2 means that it occupies 2 consecutive REs in the frequency domain and 1 consecutive RE in the time domain (corresponding to the above fd-CDM2 pattern type, indicating that the pattern occupies 2 consecutive REs in the frequency domain and 1 consecutive RE in the time domain). 2 ports use the CDM method based on FD-2OCC to occupy the same RE positions for transmission, that is, each port occupies 2 REs, and different OCCs are used to distinguish 2 ports (corresponding to each port occupying 2 REs above, and each port corresponding to a different OCC).

[0926] Part Two, the frequency domain position indication of a CSI-RS resource with more than 32 ports supports at least one of the following methods:

[0927] Option1: When a CSI-RS with more than 32 ports is aggregated by cdm16-FD4-TD4 and / or cdm32-FD4-TD8, the position of (the CDM groups included in the CSI-RS pattern) within a PRB is indicated by a 3-bit bitmap [b 2 b 1 b 0 through higher layer parameters (such as RRC (Radio Resource Control)). The starting position k i-1 in the frequency domain of the CDM group = 4f(i), where f(i) is the subscript index x of the i-th b x with a set value of 1 in the bitmap. i ∈ {1, 2, 3}. Specifically, for example, if the bitmap is 110, starting from the least significant bit (i.e., the rightmost 0), the first (i = 1) b 1 with a set value of 1 is (x = 1), so f(1) = x = 1. Therefore, when i = 1, k 0 = 4 × f(1) = 4 × 1. Similarly, when i = 2, k 1 = 4 × f(2) = 4 × 2. This Option corresponds to the case where the above CSI-RS pattern is obtained by aggregating the cdm16-FD4-TD4 pattern type and / or the cdm32-FD4-TD8 pattern type. The position of the CDM groups included in the CSI-RS pattern within a PRB is indicated by a higher layer parameter through a 3-bit bitmap, and the bitmap is composed of the set value b 2 , the set value b 1 and the set value b 0 . The starting position k i-1 in the frequency domain of the CDM group = 4f(i), where f(i) is the subscript index x of the i-th b x with a set value of 1 in the bitmap, and i ∈ {1, 2, 3}.

[0928] Option2: A CSI-RS resource has only one frequency domain position indication. The subcarrier positions it occupies within a PRB are provided by a set of bitmaps through higher layer parameters. All the PRBs occupied by the CSI-RS resource have the same frequency domain position. This Option corresponds to the case where the above CSI-RS pattern corresponds to only one CDM group frequency domain position indication information. The subcarrier positions occupied by the CSI-RS pattern within a PRB are indicated by a higher layer parameter through a set of bitmaps, and all the PRBs occupied by the CSI-RS pattern have the same frequency domain position.

[0929] (1) It is predefined that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is one or two consecutive PRBs, corresponding to that the minimum frequency-domain resource occupied by all ports of the predefined CSI-RS pattern is one or two consecutive PRBs;

[0930] (2) A new parameter is added to indicate that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is F PRBs (F ∈ {1, 2}), which is configured by a higher-layer parameter; corresponding to the first newly added parameter configured by the higher-layer parameter above, it is used to indicate that the minimum frequency-domain resource occupied by all ports of the CSI-RS pattern is one or two PRBs.

[0931] (3) According to the number of CDM groups J corresponding to the frequency-domain position indication, the CDM group size L corresponding to the CDM group type, and the number of antenna ports X, it is determined that the minimum frequency-domain resource occupied by the CSI-RS resource is X / (J×L) PRBs; when the occupied minimum frequency-domain resource is greater than one PRB, these multiple PRBs must be consecutive (corresponding to that according to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information, it is determined that the minimum frequency-domain resource occupied by the CSI-RS pattern is X / (J×L) PRBs; the number of CDM groups J is obtained according to the CDM group frequency-domain position indication information and CDM group time-domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, X / (J×L) PRBs are consecutive). Where L ∈ {2, 4, 8, 16, 32} respectively corresponds to fd-CDM2, cdm4-FD2-TD2, cdm8-FD2-TD4, cdm16-FD4-TD4 or cdm16-FD2-TD8, cdm32-FD4-TD8.

[0932] Option 3: A CSI-RS resource has two frequency-domain position indicators, which are provided by two sets of bitmaps through higher-layer parameters. Each set of bitmaps indicates the subcarrier positions occupied within a PRB respectively; corresponding to the above-mentioned one CSI-RS pattern, there are two CDM group frequency-domain position indication information, and the two CDM group frequency-domain position indication information is indicated by higher-layer parameters through two sets of bitmaps. Each set of bitmaps indicates the subcarrier positions occupied by the CSI-RS pattern within a PRB respectively. When a CSI-RS resource uses only one frequency-domain position indicator, it means that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is one PRB; when a CSI-RS resource uses two frequency-domain position indicators, it means that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is two PRBs; the two frequency-domain positions respectively indicate the frequency-domain positions within each of the two PRBs; it can be understood that: if the bitmap of one frequency-domain position indicator is all 0 and the bitmap of the other frequency-domain position indicator has bits with value 1, then it means that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is one PRB. If the bitmaps of both frequency-domain position indicators have bits with value 1, then it means that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is two PRBs.

[0933] Option 4:

[0934] (1) It is predefined that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is one PRB or multiple consecutive subcarriers within two PRBs, and the starting frequency-domain index of the CSI-RS resource is configured by higher-layer parameters;

[0935] (2) It is predefined that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is one PRB or multiple consecutive subcarriers within two PRBs, and the starting position of the CSI-RS resource is the first subcarrier of the PRB with the smallest index value;

[0936] (3) It is predefined that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is all subcarriers of one PRB or two PRBs.

[0937] Part Three, the time-domain position of a CSI-RS resource with more than 32 ports is configured by higher-layer parameters, supporting at least one of the following methods:

[0938] Option 1: A CSI-RS resource has only one set of time-domain position indicators. That is, by l 0 and / or l 1to indicate the starting index of two sets of consecutive OFDM symbols occupied within a time slot. All time slots occupied by a CSI-RS resource have the same time domain position. This Option corresponds to the above situation where one CSI-RS pattern corresponds to only one set of CDM group time domain position indication information, and all time slots occupied by one CSI-RS pattern have the same time domain position.

[0939] (1) It is predefined that the minimum time domain resource occupied by all ports of a CSI-RS resource is one or two consecutive slots, corresponding to the minimum time domain resource occupied by all ports of the above predefined one CSI-RS pattern being one or two consecutive time slots;

[0940] (2) Optionally, a new parameter is added to indicate that the minimum time domain resource occupied by all ports of a CSI-RS resource is T slots (T ∈ {1, 2}), configured through a higher layer parameter; corresponding to the above, a second new parameter is configured through a higher layer parameter to indicate that the minimum time domain resource occupied by all ports of the CSI-RS pattern is one or two time slots.

[0941] (3) According to the number of CDM groups J corresponding to the time domain position indication, the group size L of the CDM group corresponding to the CDM group type, and the number of antenna ports X, it is determined that the minimum time domain resource occupied by the CSI-RS resource is X / (J×L) slots; when the occupied minimum time domain resource is greater than one slot, these multiple slots must be consecutive (corresponding to the above, according to the number of CDM groups J, the group size L of the CDM group, and the number of antenna ports X corresponding to the target configuration information, it is determined that the minimum time domain resource occupied by the CSI-RS pattern is X / (J×L) time slots; the number of CDM groups J is obtained according to the CDM group frequency domain position indication information and CDM group time domain position indication information included in the target configuration information, the group size L of the CDM group is obtained according to the CDM type information included in the target configuration information, and when X / (J×L) is greater than 1, X / (J×L) time slots are consecutive). Where L ∈ {2, 4, 8, 16, 32} corresponds to fd-CDM2, cdm4-FD2-TD2, cdm8-FD2-TD4, cdm16-FD4-TD4, or cdm16-FD2-TD8, cdm32-FD4-TD8 respectively.

[0942] Option 2: A CSI-RS resource has two sets of time domain position indications, that is, indicated by l 0 and / or l 1 to indicate the starting index of two sets of consecutive OFDM symbols occupied within a time slot, and indicated by l 2 and / or l 3to indicate the starting indices of two sets of consecutive OFDM symbols occupied in another consecutive time slot; corresponding to the above-mentioned one CSI-RS pattern, there are two sets of CDM group time-domain position indication information, and each set of CDM group time-domain position indication information respectively indicates the OFDM symbol positions occupied by the CSI-RS pattern in one time slot. When a CSI-RS resource uses only one set of time-domain position indication, it means that the minimum time-domain resource occupied by all ports of a CSI-RS resource is one slot; when a CSI-RS resource uses two sets of time-domain position indication, it means that the minimum time-domain resource occupied by all ports of a CSI-RS resource is two slots; the two sets of time-domain position indication respectively indicate the frequency-domain positions within each of the two slots; it can be understood that: if only one set of time-domain position indication is valid and the other set of time-domain position indication is invalid, then it means that the minimum time-domain resource occupied by all ports of a CSI-RS resource is one slot; if both sets of time-domain position indication are valid, then it means that the minimum time-domain resource occupied by all ports of a CSI-RS resource is two slots.

[0943] where l 0 ∈ {0, 1, …, 13} and l 1 ∈ {2, 3, …, 12}; l 2 ∈ {0, 1, …, 13} and l 3 ∈ {2, 3, …, 12}.

[1007] 1. Within a cdm16 - FD4 - TD4 group, 16 antenna ports use the CDM method based on FD - 4OCC + TD - 4OCC to occupy the same RE positions for transmission. Table 5 below gives one type of FD - 4OCC and TD - 4OCC. Each OCC index in the table corresponds to a CSI - RS port (corresponding to the above - mentioned cdm16 - FD4 - TD4 pattern type, the OCC includes frequency - division FD - 4OCC and time - division TD - 4OCC, and different OCC indices correspond to different FD - 4OCC and / or TD - 4OCC). This solution does not rule out the use of other orthogonal cover codes with a length of 4.

[1018]

[1019]

[1020] The above Tables 5 - 7 can be referred to each other, and the repeated parts will not be elaborated. The following is a specific example of this solution.

[1021] Example 1:

[1022] 1) The base station selects a CSI-RS pattern from the CSI-RS configuration set.

[1023] For example, it selects Configuration 2 (the parameter settings of this row) from the predefined 64-port configuration set (Table 2), and for example: l 0 = 4, k 0 = 0, k 1 = 2, k 2 = 4, k 3 = 6, density = 1; This CSI-RS pattern can achieve full power utilization and has low time-frequency position indication overhead.

[1024] 2) The base station sends the configuration information of the selected CSI-RS pattern to the terminal; corresponding to sending the target configuration information to the terminal above. The configuration information includes the number of ports (64), CDM type (cdm16-FD2-TD8), density (1), time-domain position indication (l 0 = 4) and frequency-domain position indication (001111); corresponding to the target configuration information including: the number of antenna ports, density information, CDM type information, CDM group frequency-domain position indication information, and CDM group time-domain position indication information.

[1025] 3) The base station sends the CSI-RS to the terminal according to the selected CSI-RS pattern.

[1026] The selected CSI-RS pattern is aggregated by 4 CDM16-FD2-TD8 groups, such asFigure 5 As shown; 16 antenna ports can be orthogonally transmitted within a cdm16-FD2-TD8 group, and each antenna port occupies all the REs within a cdm16-FD2-TD8 group. The 16 antenna ports within a cdm16-FD2-TD8 group are distinguished by different OCCs in Table 6.

[1027] 4) The terminal receives the configuration information of the CSI-RS; corresponding to the above-mentioned target configuration information sent by the receiving network device.

[1028] The terminal determines which row in the configuration set according to the number of ports, CDM type, density, time-domain position indication, and frequency-domain position indication in the configuration information, in combination with the predefined configuration set (see Tables 1 to 4 above). In this embodiment, it is determined to be Configuration 2. The terminal can know the pattern of the CSI-RS according to Configuration 2. Subsequently, the terminal can determine the REs occupied by the CSI-RS within a PRB and a slot according to the time-domain position indication and frequency-domain position indication in the configuration information, in combination with the pattern of the CSI-RS. In this embodiment, it can be: the REs corresponding to OFDM symbol indices 4 to 11 in the time domain and subcarrier indices 0 to 7 in the frequency domain.

[1029] 5) After the terminal resolves the time-frequency position of the CSI-RS, it receives the CSI-RS on the corresponding time-frequency resources and performs channel measurement.

[1030] Embodiment 2:

[1031] 1) The base station selects a CSI-RS pattern from the CSI-RS configuration set.

[1032] For example, Configuration 1 is selected from the predefined 64-port configuration set (Table 2), and l 0 = 4 (k has no starting position limit), and the frequency domain occupies 16 consecutive subcarriers (starting from 0 or others); this CSI-RS pattern can achieve full power utilization.

The 16 antenna ports within a cdm16-FD4-TD4 group are distinguished by different OCCs in Table 5.

[1034] 2) The base station sends the configuration information of the selected CSI-RS pattern to the terminal; corresponding to the above sending the target configuration information to the terminal. The configuration information includes the number of ports (64), CDM type (cdm16-FD4-TD4), density (0.5), time-domain position indication (l 0 =4), and frequency-domain position indication (it is predefined that the minimum frequency-domain resource occupied by all ports of a CSI-RS resource is multiple consecutive subcarriers within two PRBs, and the starting position of the CSI-RS resource is the first subcarrier of the PRB with the smallest index value); corresponding to the above target configuration information including: the number of antenna ports, density information, CDM type information, CDM group frequency-domain position indication information, and CDM group time-domain position indication information.

[1035] 3) The base station sends the CSI-RS to the terminal according to the selected CSI-RS pattern.

[1036] 4) The terminal receives the configuration information of the CSI-RS; corresponding to the above receiving the target configuration information sent by the network device.

[1037] The terminal determines which row in the predefined configuration set (refer to Tables 1 to 4 above) according to the number of ports, CDM type, density, time-domain position indication, and frequency-domain position indication in the configuration information. In this embodiment, it is determined to be Configuration 1. The terminal knows the pattern of the CSI-RS according to Configuration 1. Subsequently, the terminal can determine the REs occupied by the CSI-RS within two adjacent PRBs and one slot according to the time-domain position indication and frequency-domain position indication in the configuration information and in combination with the pattern of the CSI-RS. In this embodiment, it can be: the REs corresponding to OFDM symbol indices 4 to 7 in the time domain and subcarrier indices 0 to 11 of PRB1 and subcarrier indices 0 to 3 of PRB2 in the frequency domain.

[1038] 5) After the terminal resolves the time-frequency position of the CSI-RS, it receives the CSI-RS on the corresponding time-frequency resources and performs channel measurement.

[1039] Embodiment 3:

In this embodiment, it is determined to be Configuration 4. The terminal can know the pattern of the CSI-RS according to Configuration 4 (specifically, it can be obtained by aggregating 24-port patterns of 2 cdm8-FD2-TD4 pattern types through the TDM method). Subsequently, the terminal can determine the REs occupied by the CSI-RS in one PRB and one slot according to the time-domain position indication and frequency-domain position indication in the configuration information, combined with the pattern of the CSI-RS. In this embodiment, it can be: the REs corresponding to OFDM symbol indices 4 to 7 and 10 to 13 in the time domain and subcarrier indices 6 to 11 in the frequency domain.

[1046] 5) After the terminal resolves the time-frequency position of the CSI-RS, it receives the CSI-RS on the corresponding time-frequency resources and performs channel measurement.

[1047] Embodiment 4:

[1048] 1) The base station selects a CSI-RS pattern from the CSI-RS configuration set.

[1050] 2) The base station sends the configuration information of the selected CSI-RS pattern to the terminal; corresponding to the above sending the target configuration information to the terminal. The configuration information includes the number of ports (96), CDM type (cdm4-FD2-TD4), density (1), time-domain position indication (l 0 = 4, l 1 = 10) and frequency-domain position indication (111111); corresponding to the above target configuration information including: the number of antenna ports, density information, CDM type information, CDM group frequency-domain position indication information, and CDM group time-domain position indication information.

[1051] 3) The base station sends the CSI-RS to the terminal according to the selected CSI-RS pattern.

[1052] 4) The terminal receives the configuration information of the CSI-RS; corresponding to the above receiving the target configuration information sent by the network device.

[1053] The terminal determines which row in the configuration set according to the number of ports, CDM type, density, time-domain position indication, and frequency-domain position indication in the configuration information, combined with the predefined configuration set (see Tables 1 to 4 above). In this embodiment, it is determined to be Configuration 6. The terminal can know the pattern of the CSI-RS according to Configuration 6 (specifically, it can be obtained by aggregating 48-port patterns of 2 cdm8-FD2-TD4 pattern types through the FDM method). Subsequently, the terminal can determine the REs occupied by the CSI-RS in one PRB and one slot according to the time-domain position indication and frequency-domain position indication in the configuration information, combined with the pattern of the CSI-RS. In this embodiment, it can be: the REs corresponding to OFDM symbol indices 4 to 7 and 10 to 13 in the time domain and subcarrier indices 0 to 11 in the frequency domain.

[1054] 5) After the terminal resolves the time-frequency position of the CSI-RS, it receives the CSI-RS on the corresponding time-frequency resources and performs channel measurement.

[1055] Embodiment 5:
