[0044] The terminal receives first information sent by a network device, where the first information is used to configure N channel state information reference signal CSI-RS resources, where the N CSI-RS resources are used by the terminal to receive the CSI-RS;

[0045] The terminal determines the codebook subset constraint CBSR information corresponding to M first CSI-RS resources, where the first CSI-RS resource is a CSI-RS resource configured with CBSR information among the N CSI-RS resources, where M is less than or equal to N, and N is an integer greater than or equal to 1.

[0046] In the above embodiment, the terminal can determine the CBSR information corresponding to each first CSI-RS resource, and then reliably configure the CBSR of the CSI-RS resource, and constrain the spatial basis vector based on the CBSR, thereby improving communication reliability.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal determines the CBSR information corresponding to the first CSI-RS resource, including:

[0048] The terminal receives second information sent by the network device, where the second information includes M CBSR information;

[0049] The terminal determines, according to the second information, CBSR information corresponding to the M first CSI-RS resources.

[0050] In the above embodiment, the second information may carry M pieces of CBSR information, thereby enabling the terminal to determine the CBSR information of each first CSI-RS resource configuration based on the second information.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the M first CSI-RS resources correspond to the M CBSR information in sequence according to the size of the resource identifier.

[0052] In the above embodiment, each first CSI-RS resource can correspond to the CBSR information in sequence based on the size of the resource identifier. The terminal can determine the CBSR information corresponding to each first CSI-RS resource more accurately and quickly based on the size of the resource identifier, thereby effectively improving the efficiency and accuracy of the CBSR configuration.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the second information further includes third information, or the method includes: the terminal receiving the third information sent by the network device;

[0054] The third information is used to indicate the first CSI-RS resource. In the above embodiment, the terminal can accurately and reliably know which of the CSI-RS resources are first CSI-RS resources configured with CBSR and which are other CSI-RS resources not configured with CBSR based on the third information, thereby achieving more accurate CBSR configuration and effectively improving the reliability of CBSR configuration.

[0055] In combination with some embodiments of the first aspect, in some embodiments, the third information includes N bits, where the N bits correspond to the N CSI-RS resources respectively, and each bit in the third information is used to indicate whether the corresponding CSI-RS resource is configured with CBSR information.

[0056] In the above embodiment, each bit in the third information may indicate the CBSR configuration status of the corresponding CSI-RS resource, which can effectively ensure the reliability of the indication.

[0057] In combination with some embodiments of the first aspect, in some embodiments, the N CSI-RS resources correspond to the N bits in the third information in sequence according to the size of the resource identifier.

[0058] In the above embodiment, the arrangement of each bit in the third information can be constrained based on the size of the resource identifier of the CSI-RS resource, so that the terminal can more accurately and quickly determine whether each CSI-RS resource is configured with a CBSR based on the arrangement of each bit.

[0059] In combination with some embodiments of the first aspect, in some embodiments, each of the CBSR information includes a first information field, where the first information field is used to indicate the CSI-RS resource corresponding to the CBSR information.

[0065] In the above embodiment, a placeholder may be used to indicate that the corresponding CSI-RS resource is not configured with a CBSR, which can effectively enable the terminal to know which CSI-RS resources are not configured with a CBSR.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the N CSI-RS resources correspond to the M pieces of CBSR information and the NM placeholders, in sequence, according to the size of the resource identifier. In the above embodiment, the arrangement of the placeholders and the CBSR information can be constrained based on the resource identifier of the CSI-RS resource, thereby enabling the terminal to determine whether each CSI-RS resource is configured with a CBSR, as well as the configured CBSR information, based on the arrangement of the placeholders and the CBSR information, and the resource identifier of the CSI-RS resource.

[0128] In some embodiments, in a scenario where multiple TRPs perform coherent joint transmission (CJT), the network device may configure N TRP>1 CSI-RS resource is used to measure the downlink channel information of different TRPs to the terminal. In order to reduce beam interference between cells or terminals, the network device can configure a corresponding codebook subset restriction (CBSR) for each CSI-RS resource. The CBSR is used to constrain the terminal's selection of the spatial basis vector (SD basis). In some embodiments, the network side may not configure a CBSR for each CSI-RS resource, that is, some CSI-RS resources may not be configured with a corresponding CBSR. If a CSI-RS resource is not configured with a corresponding CBSR, the terminal can arbitrarily select the SD basis.

[0129] It can be understood that the CSI-RS resource is configured with a corresponding CBSR may mean that the network device configures corresponding CBSR information or a CBSR sequence for the CSI-RS resource.

[0130] In some embodiments, when the number of configured CSI-RS resources N TRP When >1, each CSI-RS resource may or may not be configured with a CBSR, resulting in the terminal being unable to accurately select the spatial basis vector of each CSI-RS resource, thereby reducing the reliability of communication.

[0131] In some embodiments, the correspondence between the configured CBSR and the configured CSI-RS resources can be indicated by means of CBSR information, indication parameters, placeholders, etc. configured by the network device, so that the terminal determines the mapping relationship between the configured CBSR and the configured CSI-RS resources to solve the problems that may exist in the above embodiments.

[0132] Among them, the number of CSI-RS resources N TRP It may be described as N in some embodiments described below.

[0133] FIG2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information processing method, which includes:

[0134] Step S2101: The network device sends first information to the terminal.

[0135] In some embodiments, the first information is used to configure N CSI-RS resources. Optionally, the CSI-RS resources can be used by a terminal to receive CSI-RS. Optionally, the third information is used to indicate one or more of the following information: the time domain location, the frequency domain location, and the CSI-RS resource identifier of the N CSI-RS resources.

[0136] In some embodiments, the network device configures N CSI-RS resources for the terminal using the first information. Optionally, the network device configures corresponding CBSR information for some or all of the N CSI-RS resources. Optionally, the number M of CSI-RS resources configured with corresponding CBSR information is less than or equal to N.

[0137] In some embodiments, the value of N may be a positive integer greater than or equal to 1. For example, the network device may configure four CSI-RS resources for the terminal, and the resource identifiers of the four CSI-RS resources may be 1, 2, 3, and 4, respectively.

[0138] The value of N may be determined by the network device itself, for example, according to a protocol, and the present disclosure does not limit the value of N. Furthermore, the number of ports per CSI-RS resource may be, for example, 2, 4, or 8, and the present disclosure does not limit this.

[0139] In some embodiments, the terminal receives first information sent by the network device. Optionally, the terminal determines N CSI-RS resources based on the first information.

[0140] It can be understood that after the network device configures N CSI-RS resources, it can send CSI-RS to the terminal at the time-frequency domain positions corresponding to these resources. After receiving the first information, the terminal can receive the CSI-RS at the time-frequency domain positions corresponding to these resources according to the first information, or expect to receive CSI-RS at these time-frequency domain positions.

[0141] In some embodiments, the first information may be, for example, a CSI-RS resource mapping information element (CSI-RS-ResourceMapping IE) or one or more fields in the CSI-RS resource mapping information element.

[0142] In some embodiments, the first information may be, for example, “resource configuration information”, “resource indication information”, etc. The embodiment of the present disclosure does not limit the name of the first information.

[0143] Step S2103: The network device sends third information to the terminal.

[0144] In some embodiments, the third information is used to indicate the first CSI-RS resource. Optionally, the third information is used to indicate whether each CSI-RS resource in the CSI-RS resources is configured with CBSR information. Optionally, the third information is used to indicate CSI-RS resources configured with CBSR and / or CSI-RS resources not configured with CBSR. Optionally, the second information is used to indicate whether a certain CSI-RS resource or each CSI RS resource is configured with CBSR information. Optionally, the second information is used to indicate a resource identifier corresponding to the first CSI-RS resource.

[0145] In some embodiments, the first CSI-RS resource is a CSI-RS resource configured with a corresponding CBSR among the N CSI-RS resources. Optionally, the number of first CSI-RS resources is M. Optionally, the number of first CSI-RS resources may be less than or equal to N, that is, the value of M may be less than or equal to N.

[0146] That is, among the N CSI-RS resources, some CSI-RS resources may be configured with CBSR, and some CSI-RS resources may not be configured with CBSR; or, all CSI-RS resources may be configured with corresponding CBSR.

[0147] In some embodiments, the third information may be determined by the network device based on the CBSR configuration of the N CSI-RS resources. For example, after determining to configure the CBSR for M first CSI-RS resources among the N CSI-RS resources, the network device generates the third information based on the resource identifiers of the M first CSI-RS resources.

[0148] In some embodiments, the third information may be, for example, a bitmap. The bitmap (i.e., the third information) may include N bits. Optionally, each bit in the bitmap may correspond to a CSI-RS resource. Optionally, each bit in the bitmap is used to indicate whether the corresponding CSI-RS resource is configured with a corresponding CBSR.

[0149] For example, the value of the bit in the third information can be 0 or 1. When the value of the bit is 1, the bit can be used to indicate that the corresponding CSI-RS resource is configured with the corresponding CBSR, that is, the CSI-RS resource corresponding to the bit is the first CSI-RS resource. When the value of the bit is 0, the bit can be used to indicate that the corresponding CSI-RS resource is not configured with the corresponding CBSR.

[0150] In some embodiments, the N CSI-RS resources correspond to the N bits in the third information in sequence according to the size of the resource identifier. Optionally, the bits in the third information are arranged according to the size of the resource identifier of the corresponding CSI-RS resource. The N CSI-RS resources may correspond to the N bits in the third information in ascending order, or may correspond to the N bits in the third information in descending order, which is not limited in the embodiments of the present disclosure.

[0151] Taking the order from small to large as an example, the CSI-RS resource with the smallest resource identifier value corresponds to the least significant bit (LSB) in the third information, and the CSI-RS resource with the largest resource identifier corresponds to the most significant bit (MSB) in the third information.

[0152] For example, the network device is configured with four CSI-RS resources, with resource identifiers 1, 2, 3, and 4, respectively. The CSI-RS resource with resource identifier 1 and index identifier 3 is configured with a CBSR. The third information may be a 4-bit bitmap, wherein the 4 bits correspond to the CSI-RS resources with resource identifiers 1, 2, 3, and 4, respectively. The values ​​of the first and third bits in the bitmap may be 1, and the values ​​of the second and fourth bits may be 0. For example, the bitmap may be as shown in Table 1 below:

[0153] Table 1

[0154] In some embodiments, the terminal receives the third information. Optionally, the terminal determines the first CSI-RS resource based on the third information. Optionally, the terminal determines the resource identifier corresponding to the first CSI-RS resource based on the third information.

[0155] For example, following the example corresponding to Table 1 above, after receiving the third information, the terminal can determine, based on the order of the resource identifiers of each CSI-RS resource, that the CSI-RS resources with resource identifiers 1 and 3 are configured with a CBSR, and that the CSI-RS resources with resource identifiers 2 and 4 are not configured with a CBSR. Furthermore, it can be determined that the number M of first CSI-RS resources is equal to 2, and that they are the CSI-RS resource with resource identifier 1 and the CSI-RS resource with resource identifier 3, respectively.

[0156] In some embodiments, the third information may be "CBSR configuration information", "bitmap information", etc., which is not limited in the embodiments of the present disclosure.

[0157] Step S2102: The network device sends second information to the terminal.

[0158] In some embodiments, the second information includes M CBSR information. Optionally, the second information is used to indicate the CBSR information corresponding to the first CSI-RS resource. Optionally, the second information is used to indicate the CBSR information corresponding to the first CSI-RS resource and that the second CSI-RS resource is not configured with CBSR information.

[0159] Optionally, the CBSR information may be a bit string. Optionally, the CBSR information may include a CBSR sequence, which may be a bit string. Optionally, different numbers of bits in the CBSR information or CBSR sequence may correspond to different CBSR constraints.

[0160] For example, the CBSR information may include any number of bit strings, such as 16, 43, 32, 59, or 48. The number of bits and the value of each bit in each CBSR information may be configured by the network device, and the embodiments of the present disclosure do not limit the specific values.

[0161] Optionally, the M CBSR information may form a linked list according to the order of the CBSR information, for example, the “codebookSubsetRestrictionList” in the related art, wherein the number of bits of the linked list may be the sum of the number of bits of the M bit strings in the M CBSR information.

[0162] In some embodiments, the second information may be determined by the network device based on the CBSR configuration of the N CSI-RS resources. For example, after determining to configure CBSR for M first CSI-RS resources among the N CSI-RS resources, the network device determines M pieces of CBSR information for the M first CSI-RS resources and generates the second information based on the correspondence between the CSI-RS resources and the CBSR information.

[0163] In some embodiments, the second information may include M pieces of CBSR information. Optionally, the M pieces of CBSR information correspond to M first CSI-RS resources. For example, if the value of N is 4 and there are two CSI-RS resources configured with CBSRs, the second information may include two pieces of CBSR information. These two pieces of CBSR information may correspond to the CSI-RS resource with a resource identifier of 1 and the CSI-RS resource with a resource identifier of 3, respectively. That is, the CSI-RS resources with resource identifiers 1 and 3 are first CSI-RS resources.

[0164] In some embodiments, the M first CSI-RS resources correspond to the M CBSR information in sequence according to the size of the resource identifier. Optionally, the M CBSR information are arranged in sequence according to the size of the resource identifier of the first CSI-RS resource corresponding to each CBSR information.

[0165] The M first CSI-RS resources may correspond to the M CBSR information in ascending order according to the size of the resource identifier, and accordingly, the M CBSR information is arranged in ascending order according to the size of the resource identifier of the corresponding CSI-RS resource. Alternatively, the M first CSI-RS resources may correspond to the M CBSR information in descending order according to the size of the resource identifier, and accordingly, the M CBSR information is arranged in descending order according to the size of the resource identifier of the corresponding CSI-RS resource. This is not limited in the embodiments of the present disclosure.

[0166] Taking the small to large scheme as an example, if the second information includes two CBSR information, namely CBSR-1 and CBSR-2, and the first CSI-RS resource includes CSI-RS resources with resource identifiers 1 and 4, then the CSI-RS resource with resource identifier 1 can correspond to CBSR-1, and the CSI-RS resource with resource identifier 4 can correspond to CBSR-2.

[0167] Optionally, the M first CSI-RS resources may be determined by the terminal based on the third information. Optionally, the resource identifiers of the M first CSI-RS resources may be determined based on the third information. For example, the terminal may determine, based on the third information, which CSI-RS resources corresponding to the resource identifiers are CSI-RS resources configured with CBSR. Referring to Table 1 above, the terminal may determine that the resource identifiers of the first CSI-RS resources include 1 and 3.

[0168] For example, the network device configures 4 CSI-RS resources for the terminal. The terminal determines, based on the third information, that the first CSI-RS resource among the 4 CSI-RS resources includes CSI-RS resources with resource identifiers 1 and 3, and the second information includes CBSR information 1 and CBSR information 2 in sequence. In this way, the terminal can determine that the CSI-RS resource with resource identifier 1 corresponds to CBSR information 1, and the CSI-RS resource with resource identifier 3 corresponds to CBSR information 2.

[0169] In some embodiments, the number of first CSI-RS resources is equal to N (i.e., the value of N is equal to the value of M), and the N CBSR information are arranged according to the size of the resource identifier of the corresponding CSI-RS resource, and the N CSI-RS resources correspond to the N CBSR information in sequence according to the size of the resource identifier.

[0170] In this embodiment, each of the N CSI-RS resources is configured with a corresponding CBSR, and the second information may include CBSR information corresponding to each CSI-RS resource.

[0171] The CBSR information may be arranged from small to large based on the resource identifiers of the corresponding CSI-RS resources. Accordingly, the CSI-RS resources correspond to the respective CBSR information in ascending order based on the size of the resource identifiers. Alternatively, the CBSR information may be arranged from large to small based on the resource identifiers of the corresponding CSI-RS resources. Accordingly, the CSI-RS resources correspond to the respective CBSR information in descending order based on the size of the resource identifiers. This disclosure is not limited to this.

[0172] For example, taking the small to large scheme as an example, if the network device is configured with 4 CSI-RS resources, the resource identifiers are 1, 2, 3, and 4 respectively, the second information can include 4 CBSR information, where the first CBSR information corresponds to the CSI-RS resource with a resource identifier of 1, and the last CBSR information corresponds to the CSI-RS resource with a resource identifier of 4. Accordingly, the terminal can determine the CBSR information corresponding to each CSI-RS resource based on the size order of the resource identifiers of the CSI-RS resources.

[0173] In some embodiments, each CBSR information includes a first information field. Optionally, each of the M CBSR information includes M first information fields. Optionally, the first information field is used to indicate the CSI-RS resource corresponding to the CBSR information.

[0174] For example, if the first information field in a CBSR information can be used to indicate that the resource identifier of the CSI-RS resource corresponding to the CBSR information is 3, it can be determined that the CSI-RS resource with the resource identifier 3 is configured with a CBSR and corresponds to the CBSR information.

[0175] Optionally, the first information field includes at least Optionally, the first information field may be located at a high bit of the CBSR information, or at a low bit of the CBSR information, or at any preset position, which is not limited in the embodiment of the present disclosure.

[0176] For example, taking the low bit of the first information field in the CBSR information as an example, if the network device is configured with 4 CSI-RS resources, that is, the value of N is 4, then 2 bits can be added to each CBSR information in the second information to indicate the CSI-RS resource corresponding to each CBSR information. For example, the second information includes CBSR information 1 and CBSR information 2, the values ​​of the first two bits in CBSR information 1 are 01, and the values ​​of the first two bits in CBSR information 2 are 11. It can be determined that CBSR information 1 corresponds to a CSI-RS resource with a resource identifier of 2, and CBSR information 2 corresponds to a CSI-RS resource with a resource identifier of 4.

[0177] Or, in another example, if is the first information field in the CBSR information, let is LSB, is the MSB, then Indicates the first CSI-RS resource, that is, the CSI-RS resource with the smallest resource identifier; Indicates the third CSI-RS resource, that is, the CSI-RS resource with resource identifier 3.

[0178] In some embodiments, the second information further includes NM placeholders, where the value of NM may be K. Optionally, the NM placeholders correspond to NM second CSI-RS resources, respectively. The second CSI-RS resource is different from the first CSI-RS resource. Optionally, the second CSI-RS resource is a CSI-RS resource not configured with CBSR information. Optionally, the placeholder is used to indicate that the corresponding CSI-RS resource is not configured with a CBSR.

[0179] It can be understood that the sum of the number of CSI-RS resources not configured with CBSR and the number of CSI-RS resources configured with CBSR may be the same as the number of CSI-RS resources.

[0180] For example, if the second information includes three placeholders and one CBSR information, the network device is configured with four CSI-RS resources, namely CSI-RS resource 1 to CSI-RS resource 4, where the three placeholders correspond to CSI-RS resource 1, CSI-RS resource 2 and CSI-RS resource 3, respectively. It can be determined that CSI-RS resource 1, CSI-RS resource 2 and CSI-RS resource 3 are not configured with corresponding CBSR information, and the above-mentioned one CBSR information corresponds to CSI-RS resource 4.

[0181] Optionally, the N CSI-RS resources correspond to the M CBSR information and the NM placeholders in sequence according to the size of the resource identifier. Optionally, the NM placeholders and the M CBSR information are arranged according to the size of the resource identifier of the corresponding CSI-RS resources.

[0182] Among them, the NM placeholders and the M CBSR information can be arranged from small to large according to the resource identifiers of the corresponding CSI-RS resources. Accordingly, the N CSI-RS resources correspond to the M CBSR information and the NM placeholders in order from small to large according to the size of the resource identifier. Alternatively, the NM placeholders and the M CBSR information can be arranged from large to small according to the resource identifiers of the corresponding CSI-RS resources. Accordingly, the N CSI-RS resources correspond to the M CBSR information and the NM placeholders in order from large to small according to the size of the resource identifier. This is not limited in the present embodiment.

[0183] For example, if the network device is configured with four CSI-RS resources, whose resource identifiers are, from smallest to largest, CSI-RS resource 1 to CSI-RS resource 4, where CSI-RS resource 1 and CSI-RS resource 3 are not configured with a CBSR, and CSI-RS resource 2 and CSI-RS resource 4 are configured with a CBSR, then the second information may include two placeholders and two CBSR information pieces, arranged in the order of placeholder 1 / CBSR information 1 / placeholder 2 / CBSR information 2, where placeholder 1 corresponds to CSI-RS resource 1, CBSR information 1 corresponds to CSI-RS resource 2, placeholder 2 corresponds to CSI-RS resource 3, and CBSR information 2 corresponds to CSI-RS resource 4. In this way, the terminal can determine, based on the second information and the order of the resource identifiers of the respective CSI-RS resources, that CSI-RS resource 1 and CSI-RS resource 3 are not configured with a CBSR, and that CSI-RS resource 2 and CSI-RS resource 4 correspond to CBSR information 1 and CBSR information 2, respectively.

[0184] In some embodiments, the second information may be, for example, "CodebookConfig-r18," or a field in that information element, or any other information element. Optionally, the second information and the second information may be the same or different information elements or signaling, for example, different fields in the same information element, or sent separately via two signalings. For example, the second information and the second information may be two fields in "CodebookConfig-r18," the second information may be, for example, the "n1-n2-codebookSubsetRestrictionList-r18" field under "CodebookConfig-r18," or another field under "CodebookConfig-r18."

[0185] In some embodiments, the second information may be "CBSR sequence information", "codebook indication information", "CBSR configuration information", etc. The embodiment of the present disclosure does not limit the name of the second information.

[0186] Step S2104: The terminal determines CBSR information corresponding to the M first CSI-RS resources.

[0187] In some embodiments, the terminal receives the second information and determines, based on the second information, the CBSR information corresponding to the M first CSI-RS resources. Optionally, the terminal determines the CSI-RS resources corresponding to the M CBSR information in the second information.

[0188] In some embodiments, referring to the description in step S2103, since the content included in the second information is different in different optional implementations, the terminal determines the CBSR information corresponding to the M first CSI-RS resources based on the second information, which may include multiple different optional implementations.

[0189] In order to enable those skilled in the art to better understand the various optional implementation schemes provided by the embodiments of the present disclosure, the embodiments of the present disclosure also provide the following optional embodiments:

[0190] Embodiment 1: A terminal receives second information sent by a network device, and determines CBSR information corresponding to N CSI-RS resources according to the second information.

[0191] The second information includes N pieces of CBSR information, which are arranged in ascending order according to the resource identifiers of the CSI-RS resources. The terminal determines the CBSR information corresponding to each CSI-RS resource according to the order of the sizes of the resource identifiers of the N CSI-RS resources.

[0192] Embodiment 2: The terminal receives the third information and the second information sent by the network device. The terminal determines M first CSI-RS resources based on the third information, for example, determines the resource identifier of each CSI-RS resource configured with CBSR, and determines the CSI-RS resources corresponding to the M CBSR information in the second information based on the size of the resource identifier of the M first CSI-RS resources.

[0193] Among them, the third information can be an N-bit bitmap, the second information includes M CBSR information, and the M CBSR information can be arranged in order from small to large according to the resource identifier of the first CSI RS resource. The terminal can determine the CBSR information corresponding to each first CSI-RS resource according to the order of the size of the resource identifier of the first CSI-RS resource.

[0194] Embodiment 3: The terminal receives the second information, and determines the CSI-RS resource corresponding to each CBSR information according to the first information field in the M CBSR information in the second information.

[0195] The second information includes M CBSR information, each CBSR information includes a bit number of The first information field.

[0196] Embodiment 4: The terminal receives the second information, and determines the CSI-RS resources corresponding to the M CBSR information and the NM placeholders in the second information according to the sizes of the resource identifiers of the N CSI-RS resources.

[0197] The second information may include M CBSR information and K placeholders, where the sum of M and K is equal to N. The terminal determines the CBSR information or placeholder corresponding to each CSI-RS resource according to the order of the size of the resource identifier of the CSI-RS resource.

[0198] The specific optional implementation methods of the above-mentioned embodiments 1 to 4 can be found in the relevant descriptions in steps S2101 to S2103, which will not be repeated here.

[0199] In some embodiments, M is equal to N, and the terminal determines the CBSR information corresponding to the M first CSI-RS resources according to a preset rule. Optionally, the N CSI-RS resources are all first CSI-RS resources. Optionally, the terminal does not expect to receive the second information, or the terminal does not receive the second information.

[0200] Optionally, the network device and the terminal may configure CBSR information for each CSI-RS resource by default, that is, the value of M is equal to the value of N. Alternatively, the network device may send an indication information to indicate that each CSI-RS resource is configured with a CBSR.

[0201] Optionally, each CSI-RS resource is configured with a corresponding CBSR, and the terminal determines the CBSR information corresponding to each CSI-RS resource according to a preset rule. Optionally, the network device does not send the second information, and the terminal determines the CBSR information corresponding to each CSI-RS resource according to a preset rule.

[0202] It can be understood that the preset rule adopted by the network device when configuring the corresponding CBSR information for each CSI-RS resource is the same as the preset rule adopted by the terminal to determine the CBSR information corresponding to each CSI-RS resource.

[0203] The preset rules may be, for example, rules pre-determined by a protocol, or rules indicated by a high layer, an instruction from a network device, or determined by the terminal itself, which is not limited in the embodiments of the present disclosure.

[0204] In some embodiments, the terminal determines, according to a preset rule, CBSR information corresponding to the M first CSI-RS resources, including: the terminal determines that the CBSR information corresponding to each first CSI-RS resource is first CBSR information. Optionally, the first CBSR information is pre-configured CBSR information, or is CBSR information pre-agreed upon in a protocol.

[0205] For example, the preset rule may be a rule that the CBSR information corresponding to each CSI-RS resource is the preset CBSR information, and the network device may configure the CBSR information for each CSI-RS resource according to the preset rule, and the configured CBSR information is the preset CBSR information (for example, the first CBSR information); the terminal may determine that the CBSR corresponding to each CSI-RS resource is the same according to the preset rule, and is the preset CBSR information, wherein the preset CBSR information may be indicated by the network device or determined by high-level signaling or protocol.

[0206] Alternatively, the preset rule may be a rule that the CBSR information corresponding to the CSI-RS resource whose resource identifier is less than X is the first CBSR information, and the CBSR information corresponding to the CSI-RS resource whose resource identifier is greater than or equal to X is the second CBSR information. The network device may configure the CBSR information corresponding to each CSI-RS resource based on the preset rule; the terminal may determine, according to the preset rule, that the CSI-RS resource whose resource identifier is less than X corresponds to the first CBSR information, and that the CSI-RS resource whose resource identifier is greater than or equal to X corresponds to the second CBSR information. X may be indicated by the network device or determined by the terminal itself.

[0207] By adopting the optional implementation mode in the embodiment of the present disclosure, the terminal can determine whether each CSI-RS resource configured by the network device is configured with a CBSR, and which CBSR information corresponds to the CSI-RS resource configured with the CBSR, based on the third information, the second information or the preset rule. This enables the terminal to more accurately select the corresponding spatial basis vectors in different CSI-RS resources for CSI-RS reception and CSI transmission.

[0333] FIG6A is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG6A , the embodiment of the present disclosure relates to an information processing method, which includes:

[0334] Step S6101: The network device configures corresponding CBSRs in sequence according to the order of CSI-RS resource IDs.

[0335] In some embodiments, each CSI-RS resource is independently configured with a CBSR.

[0336] In some embodiments, the network device configures the CBSR in ascending order of resource IDs, or in descending order of resource IDs.

[0337] In some embodiments, the CBSR sequence corresponding to the third CSI-RS resource is defined as being in the lowest order and then arranged sequentially according to resource ID. The third CSI-RS resource refers to the resource with the smallest CSI-RS resource ID or the resource with the largest CSI-RS resource ID. The arrangement of the lowest and highest bits in the CBSR sequence corresponding to each resource is the same as in the conventional method.

[0338] For example, it is assumed that the gNB in ​​the network device configures N for the terminal UE. TRP= 4 CSI-RS resources, with resource IDs 1, 2, 3, and 4, respectively. Each resource has 8 ports, with N1 being 2 horizontal ports and N2 being 2 vertical ports. Each CSI-RS resource is configured with a corresponding CBSR, resulting in 4 CBSR sequences of 43 bits. The sequence for each CBSR is still defined as B = B1B2, where B1 represents the K candidate beam groups and B2 indicates the amplitude constraint for each beam in each beam group.

[0339] As shown in Figure 6B, the CSI-RS ID 1 corresponding to the first CBSR sequence in the four CBSR sequences is defined. The network device can configure the second CBSR sequence, the third CBSR sequence, and the fourth CBSR sequence in order of CSI-RS ID size. The CBSR sequence corresponding to CSI-RS ID 1 is located in the lower order, and the sequence corresponding to CSI-RS ID 4 is located in the upper order.

[0340] In some embodiments, the bits from LSB to MSB in FIG. 6B may be the second information in the above embodiment.

[0341] FIG6C is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG6C , the embodiment of the present disclosure relates to an information processing method, which includes:

[0342] Step S6301: The network device configures a sequence length of N. TRP The bits indicate which CSI-RS resources are configured with CBSR and which CSI-RS resources are not configured with CBSR.

[0343] In some embodiments, the sequence N corresponding to the third CSI-RS resource is defined as TRP The least significant bit (LSB) of the bits is indicated one by one by the bits in the sequence, from LSB to MSB, in the order of the size of the CSI-RS resource ID. The third CSI-RS resource refers to the resource with the smallest CSI-RS resource ID or the resource with the largest CSI-RS resource ID.

[0344] For example, assume that the gNB configures N TRP = 4 CSI-RS resources, with resource IDs 1, 2, 3, and 4, respectively. The number of ports per resource is 8, where N1 = 2, N2 = 2, and the gNB only configures the corresponding CBSR sequence for CSI-RS ID 1 and CSI-RS ID 3.

[0345] The gNB configures a size of N for the UE. TRP=4 bits of bitmap sequence indicating which CSI-RS resources are configured with CBSR and which are not. Based on the above assumptions, the indication information configured by the gNB to the UE is shown in Table 1 of the embodiment corresponding to Figure 2.

[0346] 1 in Table 1 indicates that the corresponding CSI-RS resource is configured with a CBSR sequence, otherwise it is not configured. TRP =The LSB in the 4 bits corresponds to CSI-RS ID1, and is indicated in the order of the CSI-RS ID value. Then there is a sequence N TRP =The MSB of the 4 bits corresponds to CSI-RS ID4.

[0347] In some embodiments, the length is N TRP The sequence or bitmap of bits may be the third information in the above embodiment.

[0348] FIG6D is a flow chart of an information processing method according to an embodiment of the present disclosure. As shown in FIG6D , the embodiment of the present disclosure relates to an information processing method, which includes:

[0349] Step S6401: The network device adds an additional sequence length to each configured CBSR sequence. Indicates the corresponding CSI-RS resource.

[0350] Optionally, if the network device is configured with N TRP =1, the sequence length of B0 is empty, that is, 0 bit.

[0351] In some embodiments, the newly added bit sequence is defined to be located at the lower or upper bits of the original CBSR sequence. For example, the CBSR sequence is defined as B=B0B1B2, or B=B1B2B0. The sequence length of B0 is Definable is the least significant bit (LSB), is the most significant bit (MSB), The opposite is also possible.

[0352] For example, assume that the gNB configures N TRP = 4 CSI-RS resources, with resource IDs 1, 2, 3, and 4, respectively. The number of ports per resource is 8, where N1 = 2, N2 = 2, and the gNB only configures the corresponding CBSR sequence for CSI-RS ID 1 and CSI-RS ID 3.

[0353] Add in the configured CBSR sequence Independently indicate which CSI-RS resource the CBSR sequence corresponds to. Sequence B0 is added to the high or low bits of the original sequence B = B1B2. If B0 is added to the low bit, then B = B0B1B2. CSI-RS resources are sorted in ascending order of ID value, that is, the first CSI-RS resource, the second CSI-RS resource, the third CSI-RS resource, and the fourth CSI-RS resource are CSI-RS ID1, CSI-RS ID2, CSI-RS ID3, and CSI-RS ID4 respectively. Let is LSB, is the MSB, then Indicates the first CSI-RS resource, namely CSI-RS ID1; Indicates the third CSI-RS resource, namely CSI-RS ID3.

[0354] In some embodiments, the above-mentioned B0 may be the first information field in the above-mentioned embodiment.

[0355] In some embodiments, the sequence B=B0B1B2 may be a CBSR sequence in the first information in the above embodiment.

The number of ports per resource is 8, where N1 = 2, N2 = 2, and the gNB only configures the corresponding CBSR sequence for CSI-RS ID 1 and CSI-RS ID 3.
