[0002] This disclosure claims priority to Chinese Patent Application No. 202411806463.7, filed in China on December 10, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to an information configuration method, apparatus, device, storage medium, and computer program product. Background Technology

[0004] When sensing is introduced into a communication network, as shown in Figure 1, User Equipment (UE) 1 transmits the Physical Downlink Shared Channel (PDSCH), and UE 2 transmits sensing signals. The UE can also be referred to as a terminal. UE 1 needs to avoid the sensing symbol positions of UE 2 through rate matching. If sensing resources occupy a large amount of frequency domain resources, rate matching at the resource block (RB) level can be used, adding a rate match pattern for sensing. If sensing occupies less frequency domain resources, rate matching at the resource element (RE) level can be used. Signaling can be used to indicate the configuration of UE 2's sensing symbols, or a Zero-Power (ZP) Channel State Information Reference Signal (CSI-RS) can be used to indicate the occupancy of sensing symbols.

[0005] However, the target being sensed is unknown and subject to significant uncertainty. Therefore, during the sensing process, enhanced sensing can be achieved by using multiple base stations to sense the same target. Taking two base stations sensing the same target as an example, as shown in Figure 2, base station 1 and base station 2 communicate with UE1 via PDSCH transmission, and base station 1 and base station 2 sense the target with UE2. UE1 needs to perform rate matching on the sensing resources of base station 1 and base station 2: for RB-level rate matching, two Rate Match Patterns need to be configured; for RE-level rate matching, the sensing resources of both base stations need to be configured. Both of these methods result in significant signaling overhead.

[0006] As shown above, the relevant configuration schemes for rate matching in related technologies have drawbacks such as high signaling overhead. Summary of the Invention

[0145] To make the technical problems, technical solutions and advantages to be solved by this disclosure clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0146] The following is a brief introduction to the relevant content of this plan.

[0147] Currently, when indicating Physical Downlink Shared Channel (PDSCH) resources to a User Equipment (UE), the PDSCH resources allocated to the UE are in the form of a large, contiguous resource block. This resource block may contain some unusable "small resource blocks." If these "small resource blocks" are resources occupied by the UE (terminal) itself, such as its own reference signal or Physical Downlink Control Channel (PDCCH), no additional signaling notification is required; only the UE's rate matching behavior needs to be defined. However, if they are PDCCH resources belonging to other UEs, Long Term Evolution (LTE) Cell Reference Signal (CRS) resources, or reserved resources, additional signaling notification is required to indicate to the UE that these resources are unavailable, allowing the UE to understand that these resources cannot be used for PDSCH transmission. The rate matching signaling indication is divided into resource block (RB) level and resource element (RE) level, specifically:

[0148] (1) The RB level uses rate match pattern signaling to indicate resource occupancy. Specific configuration examples are as follows:

[0149] A set of bitmaps indicates the occupancy of time-frequency resources: Resource Blocks indicate frequency domain resource occupancy, with 1 bit in the corresponding bitmap corresponding to one Resource Block (RB); Symbols in Resource Blocks indicate time domain resource occupancy, with 1 bit in the corresponding bitmap corresponding to one symbol; Periodicity and Pattern indicate the periodic repetition of the time domain Symbols in Resource Block bitmaps. The pattern is effective throughout the entire PDSCH range according to the configured period, with each bit in the corresponding bitmap representing a time domain symbol resource (i.e., Symbols in Resource Block) bitmap, and 1 indicating the presence of a Rate Match Pattern configuration.

[0150] In addition, for a single terminal, a maximum of four Rate Match Patterns can be configured for each Bandwidth Part (BWP) and four Rate Match Patterns can be configured for each cell. That is, a maximum of four Rate Match Patterns can be configured at the BWP granularity (or level) and a maximum of four Rate Match Patterns can be configured at the cell granularity (or level).

[0151] In addition, the Rate Match Pattern can also be configured in two Rate Match Pattern Groups (Rate Match Pattern Group 1 and Rate Match Pattern Group 2).

[0152] Rate Match Patterns not included in Rate Match Pattern Group 1 and Rate Match Pattern Group 2 are static rate matching modes, meaning they contain REs that cannot be used in PDSCH. Rate Match Patterns included in Rate Match Pattern Group 1 and Rate Match Pattern Group 2 are dynamically configured rate matching modes. Whether a RB in these patterns is available in PDSCH is dynamically indicated by Downlink Control Information (DCI). The DCI uses a 2-bit Rate Matching Indicator to notify whether a Rate Match Pattern Group is active; the high-order bit represents Rate Match Pattern Group 1, and the low-order bit represents Rate Match Pattern Group 2.

[0153] (2) RE level indications include:

[0154] 1) The LTE-CRS configuration using Rate Matching Pattern indicates the location of the LTE CRS, and the UE's PDSCH avoids these locations.

[0155] 2) Configure the Zero Power Channel State Information Reference Signal (ZP CSI-RS) so that the UE's PDSCH avoids these locations.

[0156] Furthermore, in a converged network, when base station 1 and base station 2 are sensing the same target, their sensing resources are correlated. For example, base station 1 and base station 2 may operate at different frequencies and have different carrier spacing configurations; base station 1 may have a 30kHz subcarrier, while base station 2 may have a 60kHz subcarrier.

[0157] 1) Base station 1 and base station 2 are used for sensing and ranging, requiring the same distance resolution. The distance resolution is C / 2B, where C is the speed of light and B is the base station bandwidth. The frequency domain occupancy (RE) is continuous. To achieve the same resolution, base station 1 needs to use twice the number of base stations (RB), while other configurations can be the same.

[0158] 2) For speed measurement at base stations 1 and 2, the required speed resolution is the same, which is λ / 2NT, where λ is the base station wavelength, T is the symbol length, and N is the required number of symbols. The symbols occupy continuous time domain. Base station 2 requires twice the number of symbols as base station 1, while other configurations can be the same; or, if base stations 1 and 2 have different speed resolution requirements, then other multiple relationships will apply.

[0159] Based on this correlation, the same set of signaling can be used to configure the rate matching resources (corresponding to rate matching information) of the two base stations to save signaling overhead, as shown in Figure 3.

[0160] Based on the above, this disclosure addresses the problem of high signaling overhead in existing rate matching configuration schemes by providing an information configuration method applied to a first base station, as shown in Figure 4, including:

[0161] Step 41: Determine the first rate matching information of the first base station and the second rate matching information of the second base station; wherein, the number of second base stations may be at least one, but is not limited thereto.

[0162] Step 42: Send configuration information to the terminal, the configuration information being used to indicate the first rate matching information and the second rate matching information.

[0163] Regarding rate matching information, for the RB level, it can be reflected as a rate match pattern configuration (e.g., the first rate matching information is the first rate matching pattern, and the second rate matching information is the second rate matching pattern), and for the RE level, it can be reflected as specific configuration content (e.g., the first rate matching information is the position of the sensing symbol (rate matching symbol) of the first base station, and the second rate matching information is the position of the sensing symbol of the second base station). In this scheme, the configuration methods for RE and RB are the same, only the forms are different, and will not be elaborated on here.

[0164] The information configuration method provided in this embodiment determines the first rate matching information of the first base station and the second rate matching information of the second base station; sends configuration information to the terminal, the configuration information being used to indicate the first rate matching information and the second rate matching information; it can support the use of the same set of signaling to configure the rate matching information of at least two base stations, thereby saving signaling overhead and solving the problem of large signaling overhead in related configuration schemes for rate matching in related technologies.

[0165] Furthermore, the information configuration method further includes: determining first configuration information based on the first rate matching information and the second rate matching information; the first configuration information is used to determine the second rate matching information; wherein the configuration information includes the first configuration information. This can assist the terminal in accurately determining the rate matching information of the second base station. In this solution, if the configuration information does not carry the first configuration information, it can be assumed that the relevant parameters of the rate matching information of the first base station and the second base station are the same, but this is not a limitation.

[0166] The first configuration information includes at least one of the following: (1) first information, used to indicate the number of symbols corresponding to one bit in the time-domain bitmap; (2) second information, used to indicate the number of resource blocks corresponding to one bit in the frequency-domain bitmap; (3) third information, used to indicate whether the first bitmap corresponding to the second base station is inverted relative to the second bitmap corresponding to the first rate matching information; the first bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the second bitmap is of the same type as the first bitmap; (4) fourth information, used to indicate whether the third bitmap corresponding to the second base station is reversed relative to the fourth bitmap corresponding to the first rate matching information; the third bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the fourth bitmap is of the same type as the third bitmap. This can more accurately assist the terminal in determining the rate matching information of the second base station. The phrase "the second bitmap is of the same type as the first bitmap" can include: both bitmaps are time-domain bitmaps, or both are frequency-domain bitmaps, or both are time-domain bitmaps and frequency-domain bitmaps; correspondingly, the third information can be: indicating whether the time-domain bitmap corresponding to the second base station is inverted relative to the time-domain bitmap corresponding to the first rate matching information; or, indicating whether the frequency-domain bitmap corresponding to the second base station is inverted relative to the frequency-domain bitmap corresponding to the first rate matching information; or, indicating whether the time-domain bitmap corresponding to the second base station is inverted relative to the time-domain bitmap corresponding to the first rate matching information, and whether the frequency-domain bitmap corresponding to the second base station is inverted relative to the frequency-domain bitmap corresponding to the first rate matching information; but it is not limited thereto. Similarly, "the fourth bitmap is of the same type as the third bitmap" can include: both bitmaps are time-domain bitmaps, or both are frequency-domain bitmaps, or both are time-domain bitmaps and frequency-domain bitmaps; correspondingly, the fourth information can be: indicating whether the time-domain bitmap corresponding to the second base station is reversed relative to the time-domain bitmap corresponding to the first rate matching information; or, indicating whether the frequency-domain bitmap corresponding to the second base station is reversed relative to the frequency-domain bitmap corresponding to the first rate matching information; or, indicating whether the time-domain bitmap corresponding to the second base station is reversed relative to the time-domain bitmap corresponding to the first rate matching information, and whether the frequency-domain bitmap corresponding to the second base station is reversed relative to the frequency-domain bitmap corresponding to the first rate matching information; but it is not limited thereto.

[0167] Furthermore, the first configuration information also includes: fifth information, used to indicate the number of repetition cycles of the rate matching information in the time domain. This can support reducing the over-reservation of rate matching resources.

[0168] In this embodiment of the disclosure, the information configuration method further includes: sending second configuration information to the terminal, the second configuration information indicating the rate matching information groups of the first base station and the second base station (for example, applicable to case 1: the matching information indexes contained in the rate matching information group of the first base station are all the same as the matching information indexes contained in the rate matching information group of the second base station); or, sending third configuration information to the terminal, the third configuration information indicating the rate matching information group of the first base station, and the correspondence between the matching information indexes contained in the rate matching information group of the first base station and the matching information indexes contained in the rate matching information group of the second base station (for example, applicable to case 2: the matching information indexes contained in the rate matching information group of the first base station are partially the same as or completely different from the matching information indexes contained in the rate matching information group of the second base station; it may also include cases where they are completely the same). This can support the configuration of rate matching information groups. The correspondence can be indicated to the terminal by configuring semi-static parameters, but is not limited to this. Furthermore, the rate matching information group can be implemented as a rate matching pattern group, and the corresponding matching information index can be a pattern index; but is not limited to this.

[0169] Furthermore, the information configuration method further includes: sending downlink control information to the terminal, wherein the downlink control information is used to indicate the effective rate matching information group of the first base station and the second base station. This can further support saving signaling overhead.

[0170] This disclosure also provides an information configuration method applied to a terminal, as shown in Figure 5, including:

[0171] Step 51: Receive configuration information sent by the first base station, wherein the configuration information is used to indicate the first rate matching information of the first base station and the second rate matching information of the second base station;

[0172] Step 52: Determine the first rate matching information of the first base station and the second rate matching information of the second base station based on the configuration information.

[0173] The information configuration method provided in this embodiment receives configuration information sent by a first base station, the configuration information being used to indicate first rate matching information of the first base station and second rate matching information of a second base station; and determines the first rate matching information of the first base station and the second rate matching information of the second base station based on the configuration information; it can support the use of the same set of signaling to configure the rate matching information of at least two base stations, thereby saving signaling overhead and solving the problem of large signaling overhead in related configuration schemes for rate matching in related technologies.

[0174] The step of determining the first rate matching information of the first base station and the second rate matching information of the second base station based on the configuration information includes: determining the first rate matching information of the first base station based on the configuration information; and determining the second rate matching information of the second base station based on the first rate matching information and the first configuration information carried in the configuration information; wherein the first configuration information is used to determine the second rate matching information. This can assist the terminal in accurately determining the first rate matching information and the second rate matching information. In this solution, if the configuration information does not carry the first configuration information, it can be assumed that the relevant parameters of the rate matching information of the first base station and the second base station are the same, and the terminal can directly determine the first rate matching information and the second rate matching information accordingly, but it is not limited to this.

[0175] In this embodiment of the disclosure, the first configuration information includes at least one of the following: (1) first information, used to indicate the number of symbols corresponding to one bit in the time-domain bitmap; (2) second information, used to indicate the number of resource blocks corresponding to one bit in the frequency-domain bitmap; (3) third information, used to indicate whether the first bitmap corresponding to the second base station is inverted relative to the second bitmap corresponding to the first rate matching information; the first bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the second bitmap is of the same type as the first bitmap; (4) fourth information, used to indicate whether the third bitmap corresponding to the second base station is reversed relative to the fourth bitmap corresponding to the first rate matching information; the third bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the fourth bitmap is of the same type as the third bitmap. This allows the terminal to more accurately determine the second rate matching information of the second base station.

[0176] Furthermore, the first configuration information also includes: fifth information, used to indicate the number of repetition cycles of the rate matching information in the time domain. This also allows the terminal to more accurately determine the second rate matching information of the second base station, and can reduce the over-reservation of rate matching resources.

[0177] In this embodiment of the disclosure, the information configuration method further includes: receiving second configuration information or third configuration information sent by the first base station, wherein the second configuration information is used to indicate the rate matching information group of the first base station and the second base station; the third configuration information is used to indicate the rate matching information group of the first base station, and the correspondence between the matching information index contained in the rate matching information group of the first base station and the matching information index contained in the rate matching information group of the second base station; and determining the rate matching information group of the first base station and the second base station according to the second configuration information or the third configuration information. This can support accurate determination of the rate matching information group of the first base station and the second base station.

[0178] Furthermore, the information configuration method further includes: receiving downlink control information sent by the first base station, the downlink control information indicating the effective rate matching information groups of the first base station and the second base station; and determining the effective rate matching information groups of the first base station and the second base station based on the downlink control information. This allows the terminal to determine the effective rate matching information groups of at least two base stations based on one downlink control information, further supporting the saving of signaling overhead.

[0179] It should be noted that the relevant content on the first base station side and the terminal side can be referred to each other, and the repeated parts will not be repeated.

[0180] The following is an example of the information configuration method provided in the embodiments of this disclosure. The number of second base stations is one, and the rate matching information is a rate matching pattern.

[0181] To address the aforementioned technical problems, this disclosure provides an information configuration method, specifically a (cooperative awareness) rate matching pattern configuration method, which mainly involves the following parts:

[0182] 1. Base station 1 (corresponding to the first base station mentioned above) instructs base station 2 (corresponding to the second base station mentioned above) on the sensing resource configuration of base station 2, or base station 2 instructs base station 1 on the sensing resource configuration of base station 2 via signaling. That is, base station 1 configures the sensing resource configuration of base station 2 or base station 1 receives the sensing resource configuration of base station 2 fed back by base station 2.

[0183] Afterwards, base station 1 can configure its RB-level or RE-level rate matching resources (corresponding to rate matching information) according to the current configuration method;

[0184] Based on the configuration of the sensing resources of base station 2, base station 1 can add (i.e., add to the configuration information of base station 1) a first parameter set (corresponding to the above-mentioned first configuration information) to indicate the configuration parameters of base station 2, so that the UE can understand the rate matching resource configuration of base station 2, that is, determine the above-mentioned second rate matching information.

[0185] The first parameter set may include one or more of the following parameters:

[0186] Parameter 1 indicates the number of symbols corresponding to one bit in the time-domain bitmap; corresponding to the first information mentioned above, it is used to indicate the number of symbols corresponding to one bit in the time-domain bitmap.

[0187] Parameter 2 indicates the number of RBs corresponding to one bit in the frequency domain bitmap; corresponding to the second information mentioned above, it is used to indicate the number of resource blocks corresponding to one bit in the frequency domain bitmap.

[0188] Parameter 3 indicates whether the time-domain and / or frequency-domain bitmaps are inverted; corresponding to the third information above, it is used to indicate whether the first bitmap corresponding to the second base station is inverted relative to the second bitmap corresponding to the first rate matching information; the first bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the second bitmap is of the same type as the first bitmap;

[0189] Parameter 4 indicates whether the time-domain and / or frequency-domain bitmap is reversed; corresponding to the fourth information above, it is used to indicate whether the third bitmap corresponding to the second base station is reversed relative to the fourth bitmap corresponding to the first rate matching information; the third bitmap includes a time-domain bitmap and / or a frequency-domain bitmap, and the fourth bitmap is of the same type as the third bitmap.

[0190] Part 1 above can correspond to the determination of the first rate matching information of the first base station and the second rate matching information of the second base station; sending configuration information to the terminal, wherein the configuration information is used to indicate the first rate matching information and the second rate matching information.

[0191] 2. For RB-level rate matching pattern configuration, Rate Match Pattern Groups can also be configured. Due to the correlation of sensing resources among different base stations, this can still be simplified by configuring a Rate Match Pattern Group1 and a Rate Match Pattern Group2 for two base stations:

[0192] 1) Base station 1 configures a Rate Match Pattern Group for the UE, and base station 2 uses the same Rate Match Pattern Group configuration. The two base stations have the same Rate Match Pattern Group configuration, that is, the group contains the same pattern index; corresponding to the above, the second configuration information is sent to the terminal, and the second configuration information is used to indicate the rate matching information group of the first base station and the second base station.

[0193] Alternatively, (2) Base station 1 can configure semi-static parameters to represent the correspondence between base station 2 and base station 1 in the Rate Match Pattern Group. The UE can determine the group configuration of base station 2 based on the group configuration of base station 1. It can also send third configuration information to the terminal as described above. The third configuration information is used to indicate the rate matching information group of the first base station and the correspondence between the matching information index contained in the rate matching information group of the first base station and the matching information index contained in the rate matching information group of the second base station.

[0194] Subsequently, a DCI can be used to indicate whether the Rate Match Pattern Group of the two base stations is effective; corresponding to the downlink control information sent to the terminal as described above, the downlink control information is used to indicate the effective rate match pattern group of the first base station and the second base station.

[0195] The following provides specific examples of the solutions provided in the embodiments of this disclosure.

[0196] Example 1 [Configuration of Rate Match Pattern]:

[0197] 1. Base station 1 configures sensing resources for base station 2, and base station 1 (can determine the rate matching pattern of base station 2 based on the sensing resources configured for base station 2)

[0198] 2. Base station 1 configures the Rate Match Pattern for the UE, adding a configuration based on the original Rate Match Pattern (which can correspond to the first configuration information mentioned above, used to determine the Rate Match Pattern of base station 2). This new configuration is optional.

[0199] 3. The UE's understanding of the Rate Match Pattern of base station 1 can be consistent with the current scheme: Under the bitmaps parameter, Resource Blocks is used to represent the frequency domain resource occupancy, with each bit corresponding to an RB, and mapped from low frequency to high frequency in sequence; Symbols In Resource Block is used to represent the time domain resource occupancy, with each bit corresponding to a symbol, and mapped from front to back in sequence.

[0200] For base station 2, the UE uses the same bitmaps, but has a new understanding of the mapping relationship: the mapping is performed according to the newly added parameter Collaborative Cell Pattern 1 (i.e., the newly added configuration of base station 1 in the above 2) (which can correspond to the second rate matching information of the second base station determined according to the first rate matching information and the first configuration information carried by the configuration information). If there are multiple cooperating base stations, Collaborative Cell Pattern 2, 3... can be configured.

[0201] The newly added parameters are configurable items. If not configured, they will be mapped using the default method (e.g., the same as base station 1). Specifically, the newly added parameters may include at least one of the following parameter items:

[0202] Symbol Number Per Bit: This indicates how many symbols correspond to one bit in the Symbols In Resource Block Bitmap, and can be configured as 1, 2, ...; this parameter corresponds to the first piece of information mentioned above.

[0203] RB Number Per Bit: This indicates how many RBs correspond to one bit in the Resource Blocks Bitmap, and can be configured as 1, 2, 3, ...; this parameter corresponds to the second information mentioned above.

[0204] Invert: Indicates whether to invert Symbols In Resource Block and / or Resource Blocks. The parameter can be Symbols In Resource Block and / or Resource Blocks, that is, the information under this parameter (which is relative to the corresponding information of base station 1) is inverted; this parameter can correspond to the third information mentioned above.

[0205] Reverse Order: Indicates whether to reverse the bitmap of Symbols In Resource Block and / or Resource Blocks. The parameter can be Symbols In Resource Block and / or Resource Blocks, that is, the information under this parameter (relative to the corresponding information of base station 1) is reversed; this parameter can correspond to the fourth information mentioned above.

[0206] Number of Periods: This indicates the number of repetition periods in the time domain (i.e., the number of times the pattern repeats in the time domain; it can be configured as 1, 2, 3, ...). If not configured, it indicates that the pattern repeats throughout the entire PDSCH range (without a limit on the number of times). If configured, it indicates the total number of repetitions of the pattern. This parameter corresponds to the fifth piece of information mentioned above, used to indicate the number of repetition periods of rate matching information in the time domain. The specific repetition method can be determined using current methods, such as determining it based on Periodicity And Pattern and Symbols In Resource Block, but it is not limited to these methods.

[0207] Based on the above, more specific examples would be:

[0208] (1) For example, the Resource Blocks configured in Rate Match Pattern are: 1111110 0000000; Symbols In Resource Block is: 1110000; then the pattern corresponding to base station 1 is shown in Figure 6.

[0209] For base station 2, in Collaborative Cell Pattern 1:

[0210] 1) If only RB Number Per Bit: 2 is configured, then the pattern corresponding to base station 2 is shown in Figure 7.

[0211] 2) If only Symbol Number Per Bit: 2 is configured, then the pattern corresponding to base station 2 is shown in Figure 8.

[0212] 3) If only Invert: Symbols In Resource Block is configured, the pattern corresponding to base station 2 is shown in Figure 9.

[0213] 4) If only Invert: Resource Blocks, Symbols In Resource Block are configured, then the pattern corresponding to base station 2 is shown in Figure 10.

[0214] Alternatively, (2) for example, the Resource Blocks configured in the Rate Match Pattern are: 1010000 0000000; Symbols In Resource Block is: 1010110; then the pattern corresponding to base station 1 is shown in Figure 11.

[0215] For base station 2, in Collaborative Cell Pattern 1:

[0216] 1) If only Reverse Order: Resource Blocks is configured, the pattern corresponding to base station 2 is shown in Figure 12.

[0217] 2) If only Reverse Order: Symbols In Resource Block is configured, then the pattern corresponding to base station 2 is shown in Figure 13.

[0218] 3) If only Reverse Order: Resource Blocks, Symbols In Resource Block, RB Number Per Bit: 2, Symbol Number Per Bit: 2 are configured, then the pattern corresponding to base station 2 is shown in Figure 14.

[0219] Example 2 [A Rate Match Pattern Group, with consistent understanding between the two base stations]:

[0220] Assuming that the Rate Match Pattern is configured as shown in Figure 15, the Rate Match Pattern of base station 1 is shown in Figure 16. The Rate Match Pattern of base station 1 and / or base station 2 can be obtained according to the method in Embodiment 1, but is not limited thereto.

[0221] The Rate Match Pattern configuration includes two groups, such as Rate Match Pattern Group1 and Rate Match Pattern Group2. This corresponds to sending the second configuration information to the terminal, whereby the second configuration information indicates the rate matching information group of the first base station and the second base station.

[0222] Then, a 2-bit DCI can be used to indicate whether the two Rate Match Pattern Groups are effective; this corresponds to sending downlink control information to the terminal as described above, whereby the downlink control information is used to indicate the effective rate matching information groups of the first base station and the second base station.

[0223] For example, Rate Match Pattern Group 1 in base station 1 is configured with patterns 1 and 2, and Rate Match Pattern Group 2 is configured with patterns 3 and 4. The Rate Match Pattern Group configuration in base station 2 is the same as that in base station 1 (i.e., the pattern indices contained in the Rate Match Pattern Group are identical). When the Rate matching indicator in the DCI of base station 1 is configured as 11, patterns 1, 2, 3, and 4 of both base station 1 and base station 2 are effective (corresponding to the above-mentioned determination of the rate matching information groups of the first and second base stations based on the second configuration information; receiving downlink control information sent by the first base station, the downlink control information being used to indicate the effective rate matching information groups of the first and second base stations; determining the effective rate matching information groups of the first and second base stations based on the downlink control information), and the UE's PDSCH needs to avoid these locations.

[0224] Based on the above, Example 2 can be understood as follows: the same pattern indication is used for multiple base stations (i.e., the pattern index contained in the Rate Match Pattern Group is the same, and the subsequent indication is also for the same pattern group for multiple base stations). For example, if base station 1 DCI indication group 1 is valid, then the UE determines that Rate Match Pattern Group 1 is effective for the relevant base stations. The specific pattern configuration of each base station can be pre-configured to the terminal, but it is not limited to this.

[0225] Example 3 [Configure the correspondence between the Pattern ID of base station 2 (corresponding to the pattern index) and the Pattern ID of base station 1, (for group pattern configuration) the UE's understanding of the two base stations is inconsistent]:

[0226] Assumptions: Base stations 1 and 2 have the same Rate Match Pattern, as shown in Figure 17; Rate Match Pattern Group 1 in base station 1 is configured with pattern 1 and 2, and Rate Match Pattern Group 2 is configured with pattern 2 and 3.

[0227] Among them, base station 1 can be configured with semi-static parameters (which may be included in the third configuration information mentioned above) to the UE to indicate the correspondence between the Rate Match Pattern Group of base station 2 and the Rate Match Pattern Group of base station 1 (which may correspond to the correspondence between the matching information index contained in the rate matching information group of the first base station and the matching information index contained in the rate matching information group of the second base station), for example as follows:

[0228] Rate Match Pattern Id For Group1, Rate Match Pattern Id+1;

[0229] Rate Match Pattern Id For Group2, Rate Match Pattern Id+1;

[0230] That is, in the same group (such as Rate Match Pattern Group1 of base station and Rate Match Pattern Group1 of base station 2), the Rate Match Pattern Id of base station 2 is equal to the Rate Match Pattern Id of base station 1 + 1; where Rate Match Pattern Id For Group refers to the rate matching pattern identifier of the group, and Rate Match Pattern Id refers to the rate matching pattern identifier.

[0231] Then, the UE can determine the following based on the above parameter and the Rate Match Pattern Group configuration of base station 1: the Rate Match Pattern Group 1 of base station 2 is configured with pattern 2 and 3, and the Rate Match Pattern Group 2 of base station 2 is configured with pattern 3 and 4.

[0232] Subsequently, base station 1 and base station 2 can share the DCI indication of base station 1. For example, when the Rate Matching Indicator in the DCI of base station 1 is configured as 10, the Rate Matching Pattern Group 1 of both base station 1 and base station 2 is effective, and the UE's PDSCH needs to avoid these positions (pattern 1, 2, 3). Corresponding to the above, the rate matching information group of the first base station and the second base station can be determined according to the third configuration information. The downlink control information sent by the first base station is received, and the downlink control information is used to indicate the effective rate matching information group of the first base station and the second base station. The effective rate matching information group of the first base station and the second base station is determined according to the downlink control information.

[0233] Among them, Embodiment 2 and Embodiment 3 above can be parallel, and only one interpretation of the embodiment can be configured for the UE, but it is not limited thereto.

[0234] Therefore, the solutions provided by the embodiments of this disclosure mainly include:

[0235] 1. Use a rate matching indicator (corresponding to the above configuration information) to implement rate matching resource configuration for multiple base stations. In order for the UE to understand the different configurations of multiple base stations, some configurations can be added to indicate relevant information, such as indicating at least one of the following: the number of symbols corresponding to one bit in the time-domain bitmap; the number of RBs corresponding to one bit in the frequency-domain bitmap; whether the time-domain and / or frequency-domain bitmaps are inverted; whether the time-domain and / or frequency-domain bitmaps are reversed.

[0236] 2. Multiple base stations use the same Rate Match Pattern Group configuration, and the group configurations of multiple base stations are the same; or, the base station configures semi-static parameters to the UE to indicate the correspondence between the Rate Match Pattern Groups of other base stations (such as base station 2 above) and the first base station (such as base station 1 above), so that the UE can determine the Rate Match Pattern Group configuration of each base station;

[0237] Afterwards, the same DCI (sent by base station 1) can be used to indicate whether the Rate Match Pattern Group is effective for multiple base stations.

[0238] 3. For the time period of the Rate Match Pattern, a number of time-domain repetition periods can be configured (corresponding to the fifth information above); that is, the number of periods shown in Example 1 is added, but it is not limited to this.

[0239] In summary, this disclosure proposes a rate matching pattern configuration scheme for multiple base stations sensing the same target scenario: the same rate matching configuration (corresponding to the above configuration information) can be used to indicate the rate matching patterns of at least two base stations. Although this is less flexible than configuring two base stations individually, the sensing patterns are relatively fixed and do not require much flexibility, so this scheme will not have a substantial impact on this, and it can save signaling overhead. In addition, this disclosure also sets a number of time-domain repetition cycles to reduce the excessive reservation of rate matching resources and avoid resource waste, considering that the sensing time-domain resources may be less occupied.

[0240] It should be noted that the above embodiments can be used alone, or in combination with Embodiment 1 and Embodiment 2 or Embodiment 3; in addition, the relevant contents of the above embodiments can be referred to each other, and the repeated parts will not be described again.
