Description

[Technical Field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to a resource restriction indication method, device, and storage medium. [Background technology]

[0002] In new radio technology (NR), for example, when the communication frequency band is frequency range 2, high-frequency channel attenuation is rapid, so beam-based transmission and reception is required to ensure coverage range.

[0003] In related technologies, in order to improve the quality of communication services, it is necessary to perform resource restriction indication, such as codebook subset restriction (CBSR) and / or amplitude subset restriction. Codebook subset restriction is used to inform a terminal which codebook cannot be used, i.e., which beam cannot be used, because it may cause interference to neighboring cells. Amplitude subset restriction plays a similar role to codebook subset restriction, for example, a specific beam is not restricted as being completely unusable, but the maximum amplitude value of this beam is restricted, thereby avoiding large interference.

[0004] The above resource restriction indication method mainly targets communication transmission from one Transmission Reception Point (TRP). However, to improve edge coverage and provide equal service quality to each user within a service area, if a network device (e.g., a base station) has multiple Transmission Reception Points (TRPs), it can provide service to terminals using multiple TRPs (mTRPs) / panels. If a network device configures one Channel Measurement Resource (CMR) to include N channel state information reference signal (CSI-RS) resources, this means that the network device indicates N TRPs, where N is a positive integer.

[0005] When a CMR including N CSI-RSs is configured in a terminal, how to configure a resource restriction indication method for the N CSI-RSs is an issue that needs to be resolved. Summary of the Invention [Problem to be solved by the invention]

[0018] Illustrative embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present disclosure.

[0019] The resource restriction indication method of the embodiment of the present disclosure can be applied to the wireless communication system shown in Figure 1. Referring to Figure 1, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device via wireless resources and performs data transmission.

[0020] 1 is only a schematic illustration, and the wireless communication system may further include other network devices not shown in FIG 1, such as a core network device, a wireless relay device, and a wireless backhaul device. The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

[0021] Furthermore, the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system may employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance (CSMA). Based on factors such as different network capacities, speeds, and delays, networks can be divided into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks such as 5G networks, which may also be referred to as new radio networks (NR). For ease of explanation, this disclosure may refer to a wireless communication network as a network.

[0022] Furthermore, a network device according to the present disclosure may also be referred to as a radio access network device. This radio access network device may be a base station, an evolved node B (base station), a femtocell, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc., or may be a gNB in ​​an NR system, or may be a component or part of a device constituting a base station. Note that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device. In the present disclosure, a network device provides communication coverage for a specific geographical area and can communicate with terminals located within this coverage area (cell). Furthermore, in the case of a vehicle-to-everything (V2X) communication system, the network device may be an in-vehicle device.

[0023] Furthermore, the terminal according to the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device for providing voice and / or data communication to a user. For example, the terminal may be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include a mobile phone, customer premises equipment (CPE), pocket personal computer (PPC), handheld computer, personal digital assistant (PDA), laptop computer, tablet PC, wearable device, or in-vehicle device. Furthermore, in the case of a vehicle-to-everything (V2X) communication system, the terminal device may be an in-vehicle device. The embodiments of the present disclosure do not limit the specific technology and device form adopted by the terminal.

[0024] In related technologies, in order to improve the quality of communication services, it is necessary to perform resource restriction indication, such as codebook subset restriction (CBSR) and / or amplitude subset restriction. Codebook subset restriction is used to inform a terminal which codebook cannot be used, i.e., which beam cannot be used, because it may cause interference to neighboring cells. Amplitude subset restriction plays a similar role to codebook subset restriction, for example, a specific beam is not restricted as being completely unusable, but the maximum amplitude value of this beam is restricted, thereby avoiding large interference.

[0025] In addition, Coordinated Multiple Point transmission (CoMP) technology will be introduced to provide more balanced service quality within the service area.

[0026] Multipoint coordinated transmission technologies are generally classified into two types: coherent joint transmission (CJT) and non-coherent joint transmission (NCJT). CJT refers to mapping each data stream to an m-TRP / Panel participating in coordination via a weighting vector. CJT is equivalent to splicing multiple subarrays to form a higher-dimensional virtual array, thereby achieving high beamforming or precoding gain.

[0027] The 3rd Generation Partnership Project (3GPP) working group has been discussing whether a base station can provide CJT services on the physical downlink shared channel (PDSCH) for a terminal using up to four TRPs. Currently, it is agreed that if a base station sets a CMR that includes N CSI-RS resources, this means that the base station has instructed N TRPs.

[0028] The number of ports corresponding to each CSI-RS is the same. The number of ports that can be configured for each CSI-RS is shown in Table 1.

[0029] [Table 1]

[0030] P CSI-RSis the number of ports corresponding to the CSI-RS, N1 represents the number of antenna ports in the first dimension, N2 represents the number of antenna ports in the second dimension, O1 represents the oversampling rate in the first dimension, and O2 represents the oversampling rate in the second dimension.

[0031] In the conventional case, when considering the transmission of one TRP, the codebook restrictions of the Rel-16 Type II codebook and the Rel-17 port selection codebook are as follows:

[0032] [Table 2] TIFF2025540464000004.tif212170TIFF2025540464000005.tif62170

[0033] SEQUENCE represents the codebook sequence, codebookSubsetRestriction represents the codebook subset restriction, BIT STRING represents a bit string, CodebookConfig represents the codebook configuration parameter, codebookType represents the codebook type, typeI-SinglePanel represents single panel type I, and nrOfAntennaPorts represents the number of ports of the CSI-RS. The above codebook restriction indicates that when a single panel serves a terminal, codebook subset restriction bit strings with different sizes can be set for cases where the CSI-RS has different numbers of ports.

[0034] When a CMR including N CSI-RSs is configured in a terminal, how to configure a resource restriction indication method for the N CSI-RSs is an issue that needs to be resolved.

[0035] In view of this, the present disclosure provides a resource restriction indication method, which configures at least one channel measurement resource including N channel state information reference signal (CSI-RS) resources based on first configuration information received by a terminal, obtains a resource restriction indication corresponding to the N CSI-RS resources based on second configuration information received by the terminal, and provides resource restriction indication for multiple CSI-RS resources in a scenario in which a network device serves a terminal using multiple TRPs, such as when one CMR configured for the terminal by the network device includes N CSI-RSs, thereby improving the CJT capability of a PDSCH.

[0036] FIG. 2 is a flowchart of a resource restriction indication method according to an exemplary embodiment, which is applied to a terminal. As shown in FIG. 2, the resource restriction indication method includes the following steps S21 to S22.

[0037] In step S21, first configuration information is received, and the first configuration information is used to configure at least one channel measurement resource, where the at least one channel measurement resource includes N channel state information reference signal (CSI-RS) resources.

[0038] N is a positive integer.

[0039] In step S22, second configuration information is received, and the second configuration information is used to indicate a resource restriction indication corresponding to the N CSI-RS resources.

[0040] In an embodiment of the present disclosure, a terminal receives first configuration information, and the first configuration information can be used to configure at least one CMR, where the at least one CMR can include N channel state information reference signal (CSI-RS) resources. In one example, each CMR in the at least one CMR may include N CSI-RS resources, where N is a positive integer.

[0041] In an embodiment of the present disclosure, the terminal may further receive second configuration information, which may be used to indicate a resource restriction indication corresponding to the N CSI-RS resources. The resource restriction indication may include at least one of a Codebook Subset Restriction (CBSR) indication, an amplitude subset restriction indication, and a rank restriction indication.

[0042] By adopting the technical solution of the embodiments of the present disclosure, in a scenario in which a network device uses multiple TRPs to serve a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a resource restriction indication including a CBSR indication, an amplitude subset restriction indication, and / or a rank restriction indication for multiple CSI-RS resources is provided, thereby improving the CJT capability of the PDSCH.

[0043] In an embodiment of the present disclosure, the resource restriction indication may include a CBSR indication, and the CBSR indication may be set by a CBSR indication bit string, where the second setting information may include a CBSR indication bit string.

[0044] The CBSR indication bit string is used to set the CBSR indication corresponding to the N CSI-RS resources.

[0045] The N CSI-RS resources can correspond to one or N CBSR indications. A bitmap corresponding to the CBSR indication bit string can include multiple bits, each corresponding to a codebook subset indication, and used to indicate whether each codebook subset is restricted or not.

[0046] FIG. 3 is a flowchart of a CBSR indication method according to an exemplary embodiment. As shown in FIG. 3, the CBSR indication method includes the following step S31.

[0047] In step S31, in response to the CBSR indication bit string including a single CBSR indication bit string, the single CBSR indication bit string is set to be used to indicate that N CSI-RS resources correspond to the same CBSR indication.

[0048] In an embodiment of the present disclosure, the CBSR indication bit string may include a single CBSR indication bit string, which is used to indicate that N CSI-RS resources correspond to the same CBSR indication, where the CBSRs corresponding to the N CSI-RSs are the same. One CBSR indication bit string is used to configure the CBSRs corresponding to the N CSI-RSs.

[0049] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one CBSR indication bit string may be used to indicate CBSR indications corresponding to the N CSI-RS resources. In this case, the CBSR indication bit strings corresponding to the N CSI-RS resources are the same. Note that the CBSRs of the N CSI-RSs are all indicated by this one CBSR indication bit string, i.e., the CBSR bit strings of the N CSI-RSs are the same. In other words, the restricted codebook subsets for the N CSI-RS resources are the same.

[0050] In an embodiment of the present disclosure, since the number of ports of each CSI-RS does not exceed 32, the size of the CBSR indication bit string configured using this method of indicating that N CSI-RS resources correspond to the same CBSR indication using a single CBSR indication bit string can reuse the size of the conventional bit string. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and Rel-17 port selection codebook described above, and CBSR indication bit strings of different sizes can be selected when the CSI-RS has a different number of ports.

[0051] FIG. 4 is a flowchart of a CBSR indication method according to an exemplary embodiment. As shown in FIG. 4, the CBSR indication method includes the following step S41.

[0052] In step S41, in response to the CBSR indication bit string including a single CBSR indication bit string, the single CBSR indication bit string is configured to include N sub-bit strings, and the N sub-bit strings are configured to be used to indicate CBSR indications corresponding to the N CSI-RS resources, respectively.

[0053] In an embodiment of the present disclosure, the CBSR indication bit string may include a single CBSR indication bit string, which may include N sub-bit strings, where the N sub-bit strings are used to indicate codebook subset restriction indications corresponding to the N CSI-RS resources, respectively. Note that the CBSRs corresponding to the N CSI-RS are configured individually, and different bits in one CBSR indication bit string are used to configure the CBSRs corresponding to the N CSI-RS, and the CBSR of each CSI-RS among the N CSI-RS corresponds to some bits in this one CBSR indication bit string.

[0054] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one CBSR indication bit string can be used to indicate CBSR indications corresponding to the N CSI-RS resources. This one CBSR indication bit string can include N sub-bit strings, for example, CBSR indication sub-bit string #0, CBSR indication sub-bit string #1, ... CBSR indication sub-bit string #(N-1). In this case, the CBSR indications corresponding to the N CSI-RS resources can be indicated by the CBSR indication sub-bit string #0, CBSR indication sub-bit string #1, ... CBSR indication sub-bit string #(N-1), respectively. Each CBSR indication sub-bit string corresponds to a CBSR indication corresponding to one CSI-RS resource, and the number of bits corresponding to the CBSR indications corresponding to the N CSI-RS resources is the same, i.e., among the N CBSR indication sub-bit strings, each CBSR indication sub-bit string has the same number of bits. Furthermore, among the above N CBSR indication sub-bit strings, each CBSR indication sub-bit string may be a contiguous portion of bits in the one CBSR indication bit string, or may be a non-contiguous portion of bits in the one CBSR indication bit string. That is, the constrained codebook subsets are individually configured for the N CSI-RS resources, and the constrained codebook subsets for the N CSI-RS resources may be the same or different.

[0055] When a CBSR indication bit string is configured using such a method of indicating CBSR indications corresponding to N CSI-RS resources using different bits in a single CBSR indication bit string, if the total number of ports of the N CSI-RSs is greater than 32, the size of the conventional CBSR indication bit string cannot be reused and a new bit string length must be determined. When the length of the new bit string is determined again, the CBSR indication bit strings corresponding to the CSI-RS resources may be the same or different. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and Rel-17 port selection codebook. CBSR indication bit strings of different sizes can be selected when the CSI-RSs have different numbers of ports.

[0056] FIG. 5 is a flowchart of a CBSR indication method according to an exemplary embodiment. As shown in FIG. 5, the CBSR indication method includes the following step S51.

[0057] In step S51, in response to the CBSR indication bit string including N CBSR indication bit strings, the N CBSR indication bit strings are set to be used to indicate CBSR indications corresponding to the N CSI-RS resources, respectively.

[0058] In an embodiment of the present disclosure, the CBSR indication bit string may include N CBSR indication bit strings, which are used to indicate CBSR indications corresponding to N CSI-RS resources, respectively, where the CBSRs corresponding to the N CSI-RS are configured individually, the N CBSR indication bit strings are used to configure the CBSRs corresponding to the N CSI-RS, respectively, and the CBSR of each CSI-RS among the N CSI-RS corresponds to one CBSR indication bit string.

[0059] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N CBSR indication bit strings can be used to indicate CBSR indications corresponding to the N CSI-RS resources. For example, CBSR indication bit string #0, CBSR indication bit string #1, ... CBSR indication bit string #(N-1) can be used to indicate CBSR indications corresponding to the N CSI-RS resources, respectively. Each CBSR indication bit string corresponds to a CBSR indication corresponding to one CSI-RS resource, and the number of bits corresponding to the CBSR indications corresponding to the N CSI-RS resources is the same, i.e., among the N CBSR indication bit strings, each CBSR indication bit string has the same number of bits. Furthermore, there is a one-to-one correspondence between the N CSI-RS resources and the N CBSR indication bit strings, i.e., each CBSR indication bit string corresponds to one CSI-RS resource. That is, the restricted codebook subsets are individually configured for the N CSI-RS resources, and the restricted codebook subsets for the N CSI-RS resources may be the same or different.

[0060] The CBSR indication bit strings configured using the method of respectively indicating CBSR indications corresponding to N CSI-RS resources using N CBSR indication bit strings may reuse the size of the conventional bit string for each bit string size. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and the Rel-17 port selection codebook, and CBSR indication bit strings of different sizes may be selected when the CSI-RS has a different number of ports.

[0061] In an embodiment of the present disclosure, the second configuration information may be carried in Radio Resource Control (RRC) signaling and / or Medium Access Control (MAC CE) element signaling.

[0062] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as one CMR configured by a network device for a terminal including N CSI-RSs, a CBSR indication for common configuration or individual configuration for multiple CSI-RS resources can be provided, thereby further improving the CJT capability of the PDSCH.

[0063] In an embodiment of the present disclosure, the resource restriction indication may include an amplitude subset restriction indication, and the amplitude subset restriction may be set by first indication information, and in this case, the second setting information may include the first indication information.

[0064] The first indication information is used to indicate amplitude coefficient information that is supported or not supported by the N CSI-RS resources.

[0065] N CSI-RS resources may correspond to one or N amplitude subset restriction indications. The N amplitude subset restriction indications may be indicated by N pieces of first indication information or may be indicated by N bits included in one piece of first indication information.

[0066] FIG. 6 is a flowchart of an amplitude subset restriction indication method according to an exemplary embodiment. As shown in FIG. 6, the amplitude subset restriction indication method includes the following step S61.

[0067] In step S61, in response to the second configuration information including a single first indication information, the single first indication information is configured to be used to indicate that N CSI-RS resources correspond to the same amplitude subset restriction indication.

[0068] In an embodiment of the present disclosure, the second configuration information may include a single first indication information, and the single first indication information is used to indicate that N CSI-RS resources correspond to the same amplitude subset restriction indication, where one first indication information is used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, and the amplitude subset restriction indications corresponding to the N CSI-RS resources are the same.

[0069] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one first indication information may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, where the amplitude subset restriction indications corresponding to the N CSI-RS resources are the same, i.e., if the first indication information indicates support, all of the N CSI-RS resources support amplitude subset restriction, and if the first indication information indicates no support, none of the N CSI-RS resources support amplitude subset restriction.

[0070] FIG. 7 is a flowchart of an amplitude subset restriction indication method according to an exemplary embodiment. As shown in FIG. 7, the amplitude subset restriction indication method includes the following step S71.

[0071] In step S71, in response to the second configuration information including a single piece of first indication information, the single piece of first indication information is configured to include N bits, and the N bits are used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively.

[0072] In an embodiment of the present disclosure, the second configuration information may include a single first indication information, which may include N bits to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. Note that the amplitude subset restriction indications corresponding to the N CSI-RS resources are configured individually. One first indication information may be used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, and this one first indication information may be a bit string, which includes at least N bits, and the N bits in this bit string are used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, with each CSI-RS resource corresponding to one bit in the bit string.

[0073] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N bits in one first indication information including at least N bits can be used, for example, these N bits, bit 0, bit 1 ... bit (N-1), in the first indication information indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. That is, amplitude subset restrictions corresponding to different CSI-RS resources are configured separately, and the amplitude subset restrictions corresponding to different CSI-RS resources may be the same or different.

[0074] FIG. 8 is a flowchart of an amplitude subset restriction instruction method according to an exemplary embodiment. As shown in FIG. 8, the amplitude subset restriction instruction method includes the following step S81.

[0075] In step S81, in response to the second configuration information including N pieces of first indication information, the N pieces of first indication information are configured to respectively indicate amplitude subset restriction instructions corresponding to the N CSI-RS resources.

[0076] In an embodiment of the present disclosure, the second configuration information may include N pieces of first indication information, where the N pieces of first indication information indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, and the amplitude subset restriction indications corresponding to the N CSI-RS resources are configured separately. The N pieces of first indication information are used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, and each CSI-RS resource corresponds to one piece of first indication information.

[0077] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N pieces of first indication information may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. For example, first indication information #0, first indication information #1, ... first indication information #(N-1) may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. That is, amplitude subset restrictions corresponding to different CSI-RS resources are configured separately, and the amplitude subset restrictions corresponding to different CSI-RS resources may be the same or different.

[0078] In an embodiment of the present disclosure, the second configuration information and the first indication information may be carried in the same or different RRC signaling and / or MAC CE element signaling.

[0079] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a common or individual amplitude subset restriction indication for multiple CSI-RS resources can be provided, thereby further improving the CJT capability of the PDSCH.

[0080] In an embodiment of the present disclosure, the resource restriction instruction may include a rank restriction instruction, and the rank restriction may be set by second instruction information, where the second setting information may include second instruction information.

[0081] The second indication information is used to indicate rank information that is supported or not supported by the N CSI-RS resources.

[0082] N CSI-RS resources may correspond to one or N rank restriction indications. The N rank restriction indications may be indicated by N pieces of second indication information or may be indicated by N bits included in the second indication information.

[0083] FIG. 9 is a flowchart of a rank restriction instruction method according to an exemplary embodiment. As shown in FIG. 9, the rank restriction instruction method includes the following step S91.

[0084] In step S91, in response to the second configuration information including a single second indication information, the single second indication information is configured to be used to indicate that N CSI-RS resources correspond to the same rank restriction indication.

[0085] In an embodiment of the present disclosure, the second configuration information may include a single second indication information, and the single second indication information is used to indicate that N CSI-RS resources correspond to the same rank restriction indication, where one second indication information is used to configure the rank restriction indications corresponding to the N CSI-RS resources, and the rank restriction indications corresponding to the N CSI-RS resources are the same.

[0086] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one second indication information may be used to indicate rank restriction indications corresponding to the N CSI-RS resources. In this case, the rank restriction indications corresponding to the N CSI-RS resources are the same, i.e., when the first indication information indicates supporting ranks of 1 and 2, all of the N CSI-RS resources only support ranks of 1 and 2; when the first indication information indicates supporting ranks of 1, 2, 3, and 4, all of the N CSI-RS resources support ranks of 1, 2, 3, and 4.

[0087] FIG. 10 is a flowchart of a rank restriction instruction method according to an exemplary embodiment. As shown in FIG. 10, the rank restriction instruction method includes the following step S101.

[0088] In step S101, in response to the second configuration information including a single piece of second instruction information, the single piece of second instruction information is configured to include N sub-bit strings, and the N sub-bit strings indicate rank restriction instructions corresponding to the N CSI-RS resources, respectively.

[0089] In an embodiment of the present disclosure, the second configuration information may include a single piece of second indication information, which may include N sub-bit strings, each indicating a rank restriction indication corresponding to the N CSI-RS resources. Note that the rank restriction indications corresponding to the N CSI-RS resources are configured individually. One piece of second indication information may be used to configure the rank restriction indications corresponding to the N CSI-RS resources, and this single piece of second indication information may be a bit string, which may include at least N sub-bit strings, which may be used to configure the rank restriction indications corresponding to the N CSI-RS resources, each CSI-RS resource corresponding to one sub-bit string in the bit string.

[0090] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N sub-bit strings in one second indication information including at least N bits can be used to indicate rank restriction indications corresponding to the N CSI-RS resources, for example, N sub-bit strings of sub-bit string 0, sub-bit string 1, ... sub-bit string (N-1) in the second indication information.

[0091] FIG. 11 is a flowchart of a rank restriction instruction method according to an exemplary embodiment. As shown in FIG. 11, the rank restriction instruction method includes the following step S111.

[0092] In step S111, in response to the second configuration information including N pieces of second instruction information, the N pieces of second instruction information are configured to respectively indicate rank restriction instructions corresponding to the N CSI-RS resources.

[0093] In an embodiment of the present disclosure, the second configuration information may include N pieces of second indication information, where the N pieces of second indication information indicate rank restriction indications corresponding to the N CSI-RS resources, respectively. Note that the rank restriction indications corresponding to the N CSI-RS resources are configured individually. The N pieces of second indication information are used to configure the rank restriction indications corresponding to the N CSI-RS resources, respectively, and each CSI-RS resource corresponds to one piece of second indication information.

[0094] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N second indication information may be used to indicate rank restriction indications corresponding to the N CSI-RS resources, respectively. For example, second indication information #0, second indication information #1, ... second indication information #(N-1) may be used to indicate rank restriction indications corresponding to the N CSI-RS resources. Each second indication information includes one bit string.

[0095] In an embodiment of the present disclosure, the second configuration information and the second indication information may be carried in the same or different RRC signaling and / or MAC CE element signaling.

[0096] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a rank restriction indication for common configuration or individual configuration for multiple CSI-RS resources is provided, thereby further improving the CJT capability of the PDSCH.

[0097] FIG. 12 is a flowchart of a resource restriction instruction method according to an exemplary embodiment, which is applied to a network device. As shown in FIG. 12, the resource restriction instruction method includes the following steps S121 to S122.

[0098] In step S121, first configuration information is sent, where the first configuration information is used to configure at least one channel measurement resource, and the at least one channel measurement resource includes N channel state information reference signal (CSI-RS) resources.

[0099] N is a positive integer.

[0100] In step S122, second configuration information is sent, where the second configuration information is used to indicate a resource restriction indication corresponding to the N CSI-RS resources.

[0101] In an embodiment of the present disclosure, the network device transmits first configuration information, and the first configuration information can be used to configure at least one CMR, where the at least one CMR can include N channel state information reference signal (CSI-RS) resources. In one example, each CMR of the at least one CMR may include N CSI-RS resources, where N is a positive integer.

[0102] In an embodiment of the present disclosure, the network device may further transmit second configuration information, where the second configuration information may be used to indicate a resource restriction indication corresponding to the N CSI-RS resources. The resource restriction indication may include at least one of a Codebook Subset Restriction (CBSR) indication, an amplitude subset restriction indication, and a rank restriction indication.

[0103] By adopting the technical solution of the embodiments of the present disclosure, in a scenario in which a network device uses multiple TRPs to serve a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a resource restriction indication including a CBSR indication, an amplitude subset restriction indication, and / or a rank restriction indication for multiple CSI-RS resources is provided, thereby improving the CJT capability of the PDSCH.

[0104] In an embodiment of the present disclosure, the resource restriction indication may include a CBSR indication, and the CBSR indication may be set by a CBSR indication bit string, where the second setting information may include a CBSR indication bit string.

[0105] The CBSR indication bit string is used to set the CBSR indication corresponding to the N CSI-RS resources.

[0106] The N CSI-RS resources can correspond to one or N CBSR indications. A bitmap corresponding to the CBSR indication bit string can include multiple bits, each corresponding to a codebook subset indication, and used to indicate whether each codebook subset is restricted or not.

[0107] In an embodiment of the present disclosure, the CBSR indication bit string may include a single CBSR indication bit string, which is used to indicate that N CSI-RS resources correspond to the same CBSR indication.

[0108] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one CBSR indication bit string may be used to indicate CBSR indications corresponding to the N CSI-RS resources. In this case, the CBSR indication bit strings corresponding to the N CSI-RS resources are the same. Note that the CBSRs of the N CSI-RSs are all indicated by this one CBSR indication bit string, i.e., the CBSR bit strings of the N CSI-RSs are the same. In other words, the restricted codebook subsets for the N CSI-RS resources are the same.

[0109] In an embodiment of the present disclosure, since the number of ports of each CSI-RS does not exceed 32, the size of the CBSR indication bit string configured using this method of indicating that N CSI-RS resources correspond to the same CBSR indication using a single CBSR indication bit string can reuse the size of the conventional bit string. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and Rel-17 port selection codebook described above, and CBSR indication bit strings of different sizes can be selected when the CSI-RS has a different number of ports.

[0110] In an embodiment of the present disclosure, the CBSR indication bit string may include a single CBSR indication bit string, which may include N sub-bit strings, where the N sub-bit strings are used to indicate codebook subset restriction indications corresponding to the N CSI-RS resources, respectively. Note that the CBSRs corresponding to the N CSI-RS are configured individually, and different bits in one CBSR indication bit string are used to configure the CBSRs corresponding to the N CSI-RS, and the CBSR of each CSI-RS among the N CSI-RS corresponds to some bits in this one CBSR indication bit string.

[0111] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one CBSR indication bit string can be used to indicate CBSR indications corresponding to the N CSI-RS resources. This one CBSR indication bit string can include N sub-bit strings, for example, CBSR indication sub-bit string #0, CBSR indication sub-bit string #1, ... CBSR indication sub-bit string #(N-1). In this case, the CBSR indications corresponding to the N CSI-RS resources can be indicated by the CBSR indication sub-bit string #0, CBSR indication sub-bit string #1, ... CBSR indication sub-bit string #(N-1), respectively. Each CBSR indication sub-bit string corresponds to a CBSR indication corresponding to one CSI-RS resource, and the number of bits corresponding to the CBSR indications corresponding to the N CSI-RS resources is the same, i.e., among the N CBSR indication sub-bit strings, each CBSR indication sub-bit string has the same number of bits. Furthermore, among the above N CBSR indication sub-bit strings, each CBSR indication sub-bit string may be a contiguous portion of bits in the one CBSR indication bit string, or may be a non-contiguous portion of bits in the one CBSR indication bit string. That is, the constrained codebook subsets are individually configured for the N CSI-RS resources, and the constrained codebook subsets for the N CSI-RS resources may be the same or different.

[0112] When a CBSR indication bit string is configured using such a method of indicating CBSR indications corresponding to N CSI-RS resources using different bits in a single CBSR indication bit string, if the total number of ports of the N CSI-RSs is greater than 32, the size of the conventional CBSR indication bit string cannot be reused and a new bit string length must be determined. When the length of the new bit string is determined again, the CBSR indication bit strings corresponding to the CSI-RS resources may be the same or different. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and Rel-17 port selection codebook. CBSR indication bit strings of different sizes can be selected when the CSI-RSs have different numbers of ports.

[0113] In an embodiment of the present disclosure, the CBSR indication bit string may include N CBSR indication bit strings, which are used to indicate CBSR indications corresponding to N CSI-RS resources, respectively, where the CBSRs corresponding to the N CSI-RS are configured individually, the N CBSR indication bit strings are used to configure the CBSRs corresponding to the N CSI-RS, respectively, and the CBSR of each CSI-RS among the N CSI-RS corresponds to one CBSR indication bit string.

[0114] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N CBSR indication bit strings can be used to indicate CBSR indications corresponding to the N CSI-RS resources. For example, CBSR indication bit string #0, CBSR indication bit string #1, ... CBSR indication bit string #(N-1) are used to indicate CBSR indications corresponding to the N CSI-RS resources, respectively. Each CBSR indication bit string corresponds to a CBSR indication corresponding to one CSI-RS resource, and the number of bits corresponding to the CBSR indications corresponding to the N CSI-RS resources is the same, i.e., among the N CBSR indication bit strings, each CBSR indication bit string has the same number of bits. Furthermore, there is a one-to-one correspondence between the N CSI-RS resources and the N CBSR indication bit strings, i.e., each CBSR indication bit string corresponds to one CSI-RS resource. That is, the restricted codebook subsets are individually configured for the N CSI-RS resources, and the restricted codebook subsets for the N CSI-RS resources may be the same or different.

[0115] The CBSR indication bit strings configured using the method of respectively indicating CBSR indications corresponding to N CSI-RS resources using N CBSR indication bit strings may reuse the size of the conventional bit string for each bit string size. The size of the conventional bit string may be the size of the bit string used in the codebook subset restriction indication of the Rel-16 Type II codebook and the Rel-17 port selection codebook, and CBSR indication bit strings of different sizes may be selected when the CSI-RS has a different number of ports.

[0116] In an embodiment of the present disclosure, the second configuration information can be carried in RRC signaling and / or MAC CE element signaling.

[0117] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as one CMR configured by a network device for a terminal including N CSI-RSs, a CBSR indication for common configuration or individual configuration for multiple CSI-RS resources can be provided, thereby further improving the CJT capability of the PDSCH.

[0118] In an embodiment of the present disclosure, the resource restriction indication may include an amplitude subset restriction indication, and the amplitude subset restriction may be set by first indication information, and in this case, the second setting information may include the first indication information.

[0119] The first indication information is used to indicate amplitude coefficient information that is supported or not supported by the N CSI-RS resources.

[0120] N CSI-RS resources may correspond to one or N amplitude subset restriction indications. The N amplitude subset restriction indications may be indicated by N pieces of first indication information or may be indicated by N bits included in one piece of first indication information.

[0121] In an embodiment of the present disclosure, the second configuration information may include a single first indication information, and the single first indication information is used to indicate that N CSI-RS resources correspond to the same amplitude subset restriction indication, where one first indication information is used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, and the amplitude subset restriction indications corresponding to the N CSI-RS resources are the same.

[0122] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one first indication information may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, where the amplitude subset restriction indications corresponding to the N CSI-RS resources are the same, i.e., if the first indication information indicates support, all of the N CSI-RS resources support amplitude subset restriction, and if the first indication information indicates no support, none of the N CSI-RS resources support amplitude subset restriction.

[0123] In an embodiment of the present disclosure, the second configuration information may include a single first indication information, which may include N bits to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. Note that the amplitude subset restriction indications corresponding to the N CSI-RS resources are configured individually. One first indication information may be used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, and this one first indication information may be a bit string, which includes at least N bits, and the N bits in this bit string are used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, with each CSI-RS resource corresponding to one bit in the bit string.

[0124] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, the network device uses N bits in one first indication information including at least N bits, for example, N bits of bit 0, bit 1 ... bit (N-1) in the first indication information, to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. That is, amplitude subset restrictions corresponding to different CSI-RS resources are configured separately, and the restricted codebook subsets of the N CSI-RS resources may be the same or different.

[0125] In an embodiment of the present disclosure, the second configuration information may include N pieces of first indication information, where the N pieces of first indication information indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, and the amplitude subset restriction indications corresponding to the N CSI-RS resources are configured separately. The N pieces of first indication information are used to configure the amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively, and each CSI-RS resource corresponds to one piece of first indication information.

[0126] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N pieces of first indication information may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. For example, first indication information #0, first indication information #1, ... first indication information #(N-1) may be used to indicate amplitude subset restriction indications corresponding to the N CSI-RS resources, respectively. That is, amplitude subset restrictions corresponding to different CSI-RS resources are configured separately, and the restricted codebook subsets of the N CSI-RS resources may be the same or different.

[0127] In an embodiment of the present disclosure, the second configuration information and the first indication information may be carried in the same or different RRC signaling and / or MAC CE element signaling.

[0128] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a common or individual amplitude subset restriction indication for multiple CSI-RS resources can be provided, thereby further improving the CJT capability of the PDSCH.

[0129] In an embodiment of the present disclosure, the resource restriction instruction may include a rank restriction instruction, and the rank restriction may be set by second instruction information, where the second setting information may include second instruction information.

[0130] The second indication information is used to indicate rank information that is supported or not supported by the N CSI-RS resources.

[0131] N CSI-RS resources can correspond to one or N rank restriction indications. The N rank restriction indications may be indicated by N pieces of second indication information or may be indicated by N bits included in one piece of second indication information.

[0132] In an embodiment of the present disclosure, the second configuration information may include a single second indication information, and the single second indication information is used to indicate that N CSI-RS resources correspond to the same rank restriction indication, where one second indication information is used to configure the rank restriction indications corresponding to the N CSI-RS resources, and the rank restriction indications corresponding to the N CSI-RS resources are the same.

[0133] In one example, when a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, one second indication information may be used to indicate rank restriction indications corresponding to the N CSI-RS resources. In this case, the rank restriction indications corresponding to the N CSI-RS resources are the same. That is, when the first indication information indicates supporting ranks of 1 and 2, all of the N CSI-RS resource ranks only support ranks 1 and 2. When the first indication information indicates supporting ranks of 1, 2, 3, and 4, all of the N CSI-RS resources support ranks of 1, 2, 3, and 4.

[0134] In an embodiment of the present disclosure, the second configuration information may include a single piece of second indication information, which may include N sub-bit strings, each indicating a rank restriction indication corresponding to the N CSI-RS resources. Note that the rank restriction indications corresponding to the N CSI-RS resources are configured individually. One piece of second indication information may be used to configure the rank restriction indications corresponding to the N CSI-RS resources, and this single piece of second indication information may be a bit string, which may include at least N sub-bit strings, which may be used to configure the rank restriction indications corresponding to the N CSI-RS resources, each CSI-RS resource corresponding to one sub-bit string in the bit string.

[0135] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N sub-bit strings in one second indication information including at least N bits are used to indicate rank restriction indications corresponding to the N CSI-RS resources, for example, N sub-bit strings of sub-bit string 0, sub-bit string 1, ... sub-bit string (N-1) in the second indication information.

[0136] In an embodiment of the present disclosure, the second configuration information may include N pieces of second indication information, where the N pieces of second indication information indicate rank restriction indications corresponding to the N CSI-RS resources, respectively. Note that the rank restriction indications corresponding to the N CSI-RS resources are configured individually. The N pieces of second indication information are used to configure the rank restriction indications corresponding to the N CSI-RS resources, respectively, and each CSI-RS resource corresponds to one piece of second indication information.

[0137] In one example, if a network device configures one CMR for a terminal and this CMR includes N CSI-RS resources, N pieces of second indication information can be used to indicate rank restriction indications corresponding to the N CSI-RS resources, respectively. For example, second indication information #0, second indication information #1, ... second indication information #(N-1) can be used to indicate rank restriction indications corresponding to the N CSI-RS resources, respectively. Each second indication information includes one bit string.

[0138] In an embodiment of the present disclosure, the second configuration information and the second indication information may be carried in the same or different RRC signaling and / or MAC CE element signaling.

[0139] By adopting the technical solutions of the embodiments of the present disclosure, in a scenario where a network device uses multiple TRPs to provide services to a terminal, such as when one CMR configured by a network device for a terminal includes N CSI-RSs, a rank restriction indication for common configuration or individual configuration for multiple CSI-RS resources is provided, thereby further improving the CJT capability of the PDSCH.

[0140] In addition, the implementation of the techniques related to the process in which a network device issues a resource restriction instruction in the embodiments of the present disclosure can be applied to the process in which a terminal issues a resource restriction instruction in the embodiments of the present disclosure. Therefore, in terms of the insufficient explanation of the implementation of some techniques in the process in which a network device issues a resource restriction instruction, reference can be made to the relevant explanation of the implementation process in which a terminal issues a resource restriction instruction, and the explanation will be omitted here.

[0141] In addition, the resource restriction instruction method provided by the embodiments of the present disclosure is applied to a process of realizing a resource restriction instruction in a process of interaction between a terminal and a network device, and a detailed description of the process of realizing a resource restriction instruction through interaction between a terminal and a network device will be omitted in the embodiments of the present disclosure.

[0206] Furthermore, in this disclosure, "plurality" means two or more, and other counter classes can be understood to be similar. "And / or" describes a relation between related objects and indicates that three relations are possible. For example, a statement such as A and / or B can indicate three situations: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the related objects before and after it are in an "or" relation. The singular forms "a kind," "the," and "the" are also intended to include the plural, unless the context clearly indicates otherwise.

[0207] Furthermore, the meaning of terms such as "responsive to," "if," etc. in connection with the present disclosure will be determined by the context and actual usage scenario; for example, the word "responsive to," as used herein, can be interpreted as "when," or "in the case of," or "if."

[0208] Furthermore, while terms such as "first" and "second" describe various pieces of information, it should be understood that these pieces of information should not be limited to these terms. These terms are used merely to distinguish between pieces of information of the same type and do not imply a particular order or importance. In fact, terms such as "first" and "second" can be used completely interchangeably. For example, first information can be referred to as second information, and similarly, second information can be referred to as first information, without departing from the scope of this disclosure.

[0209] Additionally, although the embodiments of the present disclosure describe operations in a particular order in the figures, it will be understood that these operations may be performed in the particular order shown, or in a serial order, or that all operations may be required to obtain a desired result. In certain environments, multitasking and parallel processing may be advantageous.
