[0003] To support full-duplex operation on the base station side, the base station needs to configure an uplink subband (UL subband) for uplink transmission on the downlink symbol (DL symbol) or flexible symbol.

[0113] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0114] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of at least one associated listed item.

[0115] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0116] Currently, the time-frequency resources used for NR-PDCCH transmission can be determined by the following parameters:

[0117] Parameter 1, CORESET

[0118] CORESET is used to indicate the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols used in NR-PDCCH transmission and the location of the Resource Block (RB) in the frequency domain.

[0119] Specifically, the base station uses a 45-bit bitmap with a granularity of 6 RBs to indicate the RBs occupied by the CORESET in the frequency domain.

[0120] The base station indicates the number of symbols occupied by CORESET in the time domain through the duration parameter, such as occupying 1 to 3 OFDM symbols.

[0121] Parameter 2, Search Space (SS)

[0122] The SS parameter determines the absolute time-domain location of the time-frequency resources occupied by the NR-PDCCH transmission.

[0123] When downlink resources in a DL slot are divided into two or more discontinuous segments by a UL subband, refer to Figure 1 As shown, since the frequency domain resource allocation of CORESET is in 6 RB granularity, some CORESET resources may be located inside the UL subband, which means that the resources in this overlapping part cannot be used to transmit NR-PDCCH, resulting in a decrease in NR-PDCCH transmission performance.

[0124] To address the aforementioned technical problems, this disclosure provides a channel transmission method, apparatus, and storage medium. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0125] The channel transmission method provided in this disclosure will be introduced from the perspective of the terminal side first.

[0126] This disclosure provides a channel transmission method, referring to... Figure 2 As shown, Figure 2 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0127] In step 201, in response to the overlap between the control resource set CORESET and the first resource set occupied by the uplink subband, the resource set occupied by the physical downlink control channel PDCCH is determined.

[0128] In this embodiment of the disclosure, the uplink subband is located on a time unit where the transmission direction is downlink or variable.

[0129] The aforementioned time unit can be a Seamless Bidirectional Forwarding Detection (SBFD) time unit. An SBFD time unit allows for the transmission of information in different directions.

[0130] In this embodiment of the disclosure, the SBFD time unit may specifically refer to a downlink time unit that includes an uplink subband, or a variable time unit that includes an uplink subband (i.e., a time unit with a variable transmission direction).

[0131] In the embodiments of this disclosure, the time unit may be a slot, a symbol, or a duration (span), etc., and this disclosure does not limit this. A span includes multiple consecutive symbols.

[0132] In this embodiment of the disclosure, the resource set occupied by the PDCCH does not overlap with the first resource set occupied by the uplink subband.

[0133] In step 202, on the resources included in the resource set, the PDCCH sent by the base station is detected and received.

[0134] In the above embodiments, the terminal detects and receives PDCCH on the resources included in the resource set. Since the determined resource set does not overlap with the first resource set occupied by the uplink subband, the transmission performance of PDCCH can be avoided, thereby improving the reliability of full-duplex communication.

[0135] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0136] In step 301, overlapping resources that belong to both the CORESET and the first resource set are identified.

[0137] In this embodiment of the disclosure, the overlapping resource is the resource in the overlapping part of CORESET and the first resource set.

[0138] In step 302, the second resource set and the remaining resource set are determined.

[0139] In this embodiment of the disclosure, the second resource set includes at least the aforementioned overlapping resources, and CORESET includes the second resource set and the remaining resource set.

[0140] In one possible implementation, when determining the second resource set, a preset number set can be provided by the protocol. Considering that when the base station indicates the RBs occupied by the CORESET using a 45-bit bitmap, the granularity is 6 RBs, the preset number in this preset number set can be a positive integer multiple of 6. For example, the preset number set includes {6, 12, 18...}.

[0141] If the total number of RBs occupied by the second resource is equal to the first preset number included in the preset number set, then it can be determined that the second resource set only includes the overlapping resource. The first preset number can be any preset number in the preset number set.

[0142] Alternatively, if the total number of resource blocks (RBs) occupied by the second resource is not equal to any preset number in the preset number set, the terminal can determine the second preset number of RBs in the second resource set, including the overlapping resource. The second preset number can be the smallest preset number in the preset number set that is greater than the total number of RBs.

[0143] For example, if the total number of RBs occupied by overlapping resources is 3, then the second preset number is 6, and the terminal determines that the second resource set includes a total of 6 RBs, including the 3 RBs occupied by the overlapping resources.

[0144] For example, if the total number of RBs occupied by overlapping resources is 8, then the second preset number is 12. The terminal determines that the second resource set includes a total of 12 RBs, including the 8 RBs occupied by the overlapping resources.

[0145] Accordingly, after determining the second resource set, the terminal can remove the second resource from CORESET to obtain the remaining resource set.

[0146] In step 303, the remaining resource set is determined as the resource set occupied by PDCCH.

[0147] In step 304, on the resources included in the resource set, the PDCCH sent by the base station is detected and received.

[0148] In the above embodiments, the terminal can remove at least the overlapping resources that overlap with the first resource set in CORESET, determine the remaining resource set as the resource set occupied by the PDCCH, and detect and receive the PDCCH sent by the base station on the resources included in the resource set. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0149] In some alternative embodiments, refer to Figure 4 As shown, Figure 4 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0150] In step 401, overlapping resources that belong to both the CORESET and the first resource set are identified.

[0151] In this embodiment of the disclosure, the overlapping resource is the resource in the overlapping part of CORESET and the first resource set.

[0152] In step 402, the second resource set and the remaining resource set are determined.

[0153] In this embodiment of the disclosure, the second resource set includes at least the aforementioned overlapping resources, and the CORESET includes the second resource set and the remaining resource set. In one possible implementation, when determining the second resource set, the terminal may provide a preset number set via a protocol. Considering that when the base station indicates the RBs occupied by the CORESET using a 45-bit bitmap, the granularity is 6 RBs, the preset number in this preset number set can be a positive integer multiple of 6. For example, the preset number set includes {6, 12, 18…}.

[0154] If the total number of RBs occupied by the second resource is equal to the first preset number included in the preset number set, then it can be determined that the second resource set only includes the overlapping resource. The first preset number can be any preset number in the preset number set.

[0155] If the total number of resource blocks (RBs) occupied by the second resource is not equal to any preset number in the preset number set, the terminal can determine the second preset number of RBs in the second resource set, including the overlapping resource. The second preset number can be the smallest preset number in the preset number set that is greater than the total number of RBs.

[0156] Accordingly, after determining the second resource set, the terminal can remove the second resource from CORESET to obtain the remaining resource set.

[0157] In another possible implementation, CORESET can be defined as the second resource set, and correspondingly, the terminal can determine that the remaining resource set is empty.

[0158] In step 403, each of the second resources included in the second resource set is offset by a first number of RBs in the frequency domain to obtain a third resource set.

[0159] In this embodiment of the disclosure, the third resource set does not overlap with the first resource set.

[0160] In one possible implementation, the terminal may determine the first number according to the protocol.

[0161] In another possible implementation, the terminal determines the first number based on indication information sent by the base station. The indication information indicates the first number. It should be noted that if the entire CORESET is defined as the second resource set, then the third resource set obtained by offsetting the second resource set by the first number of RBs must be entirely located within the active downlink BWP.

[0162] In step 404, the union of the remaining resource set and the third resource set is determined as the resource set.

[0163] If the remaining resource set is empty, then the third resource set can be determined as the resource set occupied by PDCCH.

[0164] In step 405, on the resources included in the resource set, the PDCCH sent by the base station is detected and received.

[0165] In the above embodiments, the terminal can offset the second resource in CORESET, and determine the resource set occupied by PDCCH based on the union of the third resource set obtained after the offset and the remaining resource set. The terminal then detects and receives PDCCH sent by the base station on the resources included in this resource set. This avoids degrading the transmission performance of PDCCH and improves the reliability of full-duplex communication.

[0166] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0167] In step 501, PDCCH mapping is performed based on CORESET to determine the set of PDCCH candidate candidates.

[0168] In this embodiment of the disclosure, a PDCCH candidate refers to a resource location where a PDCCH may reside. Multiple PDCCH candidates together constitute a PDCCH candidate set.

[0169] The terminal can perform PDCCH mapping based on CORESET to determine the set of PDCCH candidates.

[0170] In step 502, a first PDCCH candidate that overlaps with the first resource set is determined from the PDCCH candidate candidate set.

[0171] In this embodiment of the disclosure, the terminal can first determine a first PDCCH candidate that overlaps with the first resource set from the PDCCH candidate set. The number of first PDCCH candidates can be one or more, and this disclosure does not limit this number.

[0172] In step 503, the first PDCCH candidate is removed from the PDCCH candidate set to obtain the remaining PDCCH candidates.

[0173] In this embodiment of the disclosure, the remaining PDCCH candidates can be obtained by directly removing the first PDCCH candidate that overlaps with the first resource set from the PDCCH candidate set.

[0174] In step 504, a PDCCH is detected and received on the remaining PDCCH candidate.

[0175] In the above embodiments, it is not necessary to change the CORESET. Instead, by removing the first PDCCH candidate that overlaps with the first resource set, the PDCCH sent by the base station is detected and received directly on the remaining PDCCH candidates. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0176] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0177] In step 601, a new CORESET is determined based on the CORESET indication information sent by the base station on resources that do not overlap with the first resource set.

[0178] In this embodiment of the disclosure, the CORESET indication information is used to indicate a new CORESET.

[0179] The terminal can determine a new CORESET based on the CORESET indication information on a resource that does not overlap with the first resource set on the activated BWP, i.e., on the actual downlink BWP.

[0180] In step 602, the new CORESET is determined as the set of resources occupied by PDCCH.

[0181] In step 603, on the resources included in the resource set, the PDCCH sent by the base station is detected and received.

[0182] In the above embodiments, the resource set occupied by the PDCCH can be determined on resources that do not overlap with the first resource set. Then, the PDCCH sent by the base station is detected and received on the resources included in the resource set. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0183] The channel transmission method provided in this disclosure will now be introduced from the perspective of the base station.

[0184] This disclosure provides a channel transmission method, referring to... Figure 7 As shown, Figure 7 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0185] In step 701, in response to the overlap between the control resource set CORESET and the first resource set occupied by the uplink subband, the resource set occupied by the physical downlink control channel PDCCH is determined.

[0186] In this embodiment of the disclosure, the uplink subband is located on a time unit where the transmission direction is downlink or variable.

[0187] The aforementioned time unit can be an SBFD time unit. An SBFD time unit allows for information transmission in different directions.

[0188] In this embodiment of the disclosure, the SBFD time unit may specifically refer to a downlink time unit that includes an uplink subband, or a variable time unit that includes an uplink subband (i.e., a time unit with a variable transmission direction).

[0189] In the embodiments of this disclosure, the time unit may be a slot, symbol, or span, etc., and this disclosure does not limit this. Among them, a span includes multiple consecutive symbols.

[0190] In this embodiment of the disclosure, the resource set occupied by the PDCCH does not overlap with the first resource set occupied by the uplink subband.

[0191] In step 702, a PDCCH is sent to the terminal on the resources included in the resource set.

[0192] In the above embodiments, the base station sends PDCCH to the terminal on the resources included in the resource set. Since the resource set does not overlap with the first resource set occupied by the uplink subband, the transmission performance of PDCCH can be avoided, thereby improving the reliability of full-duplex communication.

[0193] In some alternative embodiments, refer to Figure 8 As shown, Figure 8 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0194] In step 801, overlapping resources that belong to both the CORESET and the first resource set are determined.

[0195] In this embodiment of the disclosure, the overlapping resource is the resource in the overlapping part of CORESET and the first resource set.

[0196] In step 802, the second resource set and the remaining resource set are determined.

[0197] The method for determining the second resource set and the remaining resource set in step 802 can be similar to that in step 302 above, and will not be repeated here.

[0198] In step 803, the remaining resource set is determined as the resource set occupied by PDCCH.

[0199] In step 804, a PDCCH is sent to the terminal on the resources included in the resource set.

[0200] In the above embodiments, the base station can remove at least the overlapping resources that overlap with the first resource set from the CORESET, determine the remaining resource set as the resource set occupied by the PDCCH, and send the PDCCH to the terminal on the resources included in the resource set. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0201] In some alternative embodiments, refer to Figure 9 As shown, Figure 9 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0202] In step 901, overlapping resources that belong to both the CORESET and the first resource set are identified.

[0203] In this embodiment of the disclosure, the overlapping resource is the resource in the overlapping part of CORESET and the first resource set.

[0204] In step 902, the second resource set and the remaining resource set are determined.

[0205] The method for determining the second resource set and the remaining resource set in step 902 can be similar to that in step 402 above, and will not be repeated here.

[0206] In step 903, each of the second resources included in the second resource set is offset by a first number of RBs in the frequency domain to obtain a third resource set.

[0207] In this embodiment of the disclosure, the third resource set does not overlap with the first resource set.

[0208] In one possible implementation, the base station can determine the first number according to the protocol.

[0209] In another possible implementation, the first number can be configured by the base station. Further, the base station sends an indication message to the terminal, informing the terminal of the first number configured by the base station. It should be noted that if the entire CORESET is determined as the second resource set, then the third resource set obtained by offsetting the second resource set by the first number must be entirely within the active downlink BWP.

[0210] In step 904, the union of the remaining resource set and the third resource set is determined as the resource set.

[0211] If the remaining resource set is empty, then the third resource set can be determined as the resource set occupied by PDCCH.

[0212] In step 905, a PDCCH is sent to the terminal on the resources included in the resource set.

[0213] In the above embodiments, the base station can offset the second resource in CORESET, determine the resource set occupied by PDCCH based on the union of the third resource set obtained after the offset and the remaining resource set, and send PDCCH to the terminal on the resources included in the resource set. This avoids degrading the transmission performance of PDCCH and improves the reliability of full-duplex communication.

[0214] In some alternative embodiments, refer to Figure 10 As shown, Figure 10 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0215] In step 1001, PDCCH mapping is performed based on CORESET to determine the set of PDCCH candidate candidates.

[0216] In this embodiment of the disclosure, the base station can also perform PDCCH mapping based on the CORESET configured for the terminal, thereby determining the set of PDCCH candidate candidates.

[0217] In step 1002, a first PDCCH candidate that overlaps with the first resource set is determined from the PDCCH candidate set.

[0218] The implementation of step 1002 is similar to that of step 502 above, and will not be repeated here.

[0219] In step 1003, the first PDCCH candidate is removed from the PDCCH candidate set to obtain the remaining PDCCH candidates.

[0220] In this embodiment of the disclosure, the remaining PDCCH candidates can be obtained by directly removing the first PDCCH candidate that overlaps with the first resource set from the PDCCH candidate set.

[0221] In step 1004, a PDCCH is sent to the terminal on the remaining PDCCH candidate.

[0222] That is, the base station can send the PDCCH to the terminal on the remaining PDCCH candidates that do not overlap with the first resource set.

[0223] In the above embodiments, it is not necessary to change the CORESET. Instead, by removing the first PDCCH candidate that overlaps with the first resource set, the base station directly sends the PDCCH to the terminal on the remaining PDCCH candidates. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0224] In some alternative embodiments, refer to Figure 11 As shown, Figure 11 This is a flowchart illustrating a channel transmission method according to an embodiment, which can be executed by a base station. The method may include the following steps:

[0225] In step 1101, a new CORESET is determined on resources that do not overlap with the first resource set.

[0226] In this embodiment of the disclosure, the base station can configure a new CORESET for the terminal on resources that do not overlap with the first resource set when activating the BWP, i.e., on the actual downlink BWP.

[0227] Accordingly, the base station can send CORESET indication information to the terminal so that the terminal can determine a new CORESET on the actual downlink BWP based on the CORESET indication information.

[0228] In step 1102, the new CORESET is determined as the set of resources occupied by PDCCH.

[0229] In step 1103, a PDCCH is sent to the terminal on the resources included in the resource set.

[0230] In the above embodiments, the resource set occupied by the PDCCH can be determined on resources that do not overlap with the first resource set. The PDCCH is then sent to the terminal on the resources included in that resource set. This avoids degrading the transmission performance of the PDCCH and improves the reliability of full-duplex communication.

[0231] It should be noted that the base station can determine the set of resources occupied by the PDCCH in any of the above methods. Furthermore, the base station sends the PDCCH to the terminal on the corresponding resources. The terminal can determine the set of resources occupied by the PDCCH in the same way as the base station, and detect and receive the PDCCH on the corresponding resources.

[0232] Of course, after determining the resource set occupied by the PDCCH using any of the methods described above, the base station can also send indication information or indication messages to the terminal, informing the terminal of the resource set occupied by the PDCCH determined by the base station. Further, the base station sends the PDCCH to the terminal on the corresponding resources. Based on the indication information or indication messages sent by the base station, the terminal determines the resource set occupied by the PDCCH and can then detect and receive the PDCCH on the corresponding resources.

[0233] The base station can send indication information or indication messages to the terminal through a display method, that is, the indication information or indication message sent to the terminal directly includes the resource set determined by the base station.

[0234] Alternatively, the base station can send indication information or indication messages to the terminal implicitly. For example, when the base station sends a message to the terminal, it determines the message content corresponding to the resource set occupied by the current PDCCH based on the predefined correspondence between different contents of the message and different resource sets, and sends the message content in the message to the terminal. The terminal can also determine the resource set occupied by the PDCCH corresponding to the message content based on the above correspondence.

[0235] This disclosure does not limit the specific content or method by which the base station sends indication information or indication messages to the terminal to inform the terminal of the set of resources occupied by the PDCCH determined by the base station.

[0236] The above is merely an illustrative example. Alternatively, the terminal can determine the set of resources occupied by the PDCCH and report it to the base station. Based on the information reported by the terminal, the base station determines the set of resources occupied by the PDCCH and sends the PDCCH to the terminal on the corresponding resources. This disclosure does not limit the scope of the invention.

[0237] To facilitate understanding of the above solutions, the present disclosure provides the following embodiments.

[0238] Example 1: Assuming the terminal is a Rel-18 or later version terminal, with half-duplex or full-duplex capability, this patent does not impose any limitations. It is assumed that the base station performs full-duplex operation within the downlink time slot of the Time Division Duplex (TDD) band, that is, simultaneously scheduling downlink and uplink data.

[0239] In this embodiment, it is assumed that the CORESET configured by the base station for the terminal overlaps with the first resource set occupied by the UL subband in the SBFD time unit. In this embodiment, the SBFD time unit specifically refers to the DL time unit or flexible time unit where the UL subband exists.

[0240] As a concrete example, suppose the CORESET configured by the base station for the terminal occupies 18 consecutive RBs in the frequency domain and 3 symbols in the time domain. The frequency domain resources of the CORESET are indicated by a 45-bit bitmap, and the time domain resources are indicated by duration information as 3 consecutive OFDM symbols. Specifically, suppose the RB indices occupied by the CORESET within the active DL BWP are RB#0 to RB#17, and suppose the RB indices occupied by the UL subband within the active DL BWP are RB#15 to RB#35, referring to... Figure 12 As shown.

[0241] It should be noted that this patent does not limit the configuration or specify the reference RB used by the UL subband. This embodiment only declares the RB position occupied by the UL subband within the active BWP. The overlap relationship between the CORESET and the UL subband is also as follows: Figure 12 As shown.

[0242] In this embodiment, when some resources of CORESET overlap with the UL subband, the NR-PDCCH is transmitted in the following manner:

[0243] The base station transmits NR-PDCCH within the remaining resource set after removing the RBs that overlap with the first resource set.

[0244] When the total number of RBs occupied by overlapping resources that belong to both CORESET and the first resource set in the UL subband is less than 6, the terminal removes all 6 RBs, including the overlapping resources, from CORESET to obtain the remaining resource set.

[0245] The terminal determines the remaining resource set as the resource set occupied by the PDCCH, and detects and receives NR-PDCCH on the resources included in the resource set.

[0246] Similarly, for a base station, when the total number of RBs occupied by overlapping resources belonging to both CORESET and the first resource set in the ULsubband is less than 6, the base station will remove all 6 RBs, including overlapping resources, in CORESET.

[0247] Specifically, when the base station maps NR-PDCCH within the CORESET, it needs to remove the RBs that overlap between the CORESET and the UL subband, and map NR-PDCCH on the RBs included in the remaining resource set.

[0248] In this embodiment, since the total number of RBs occupied by overlapping resources is 3, the base station needs to remove a total of 6 RBs, including these 3 RBs. That is, the base station only performs NR-PDCCH mapping and transmission on RB#0 to RB#11. When the SBFD terminal detects and receives NR-PDCCH on the CORESET, it is also assumed that the NR-PDCCH is only mapped on RB#0 to RB#11. The terminal detects and receives the PDCCH sent by the base station on RB#0 to RB#11.

[0249] It should be noted that the method described in this embodiment can be directly applied to CORESET configurations that are discontinuous in the frequency domain. The specific method is completely consistent with the scheme for CORESET configurations that are continuous in the frequency domain, and will not be repeated here.

[0250] Example 2 assumes the terminal is a Rel-18 or later version terminal, with half-duplex or full-duplex capability, without any limitation in this patent. It is assumed that the base station performs full-duplex operation within the downlink time slot of the TDD band, that is, simultaneously scheduling downlink and uplink data.

[0251] In this embodiment, it is assumed that the CORESET configured by the base station for the terminal overlaps with the first resource set occupied by the UL subband in the SBFD time unit. In this embodiment, the SBFD time unit specifically refers to the DL time unit or flexible time unit where the UL subband exists.

[0252] As a concrete example, suppose the CORESET configured by the base station for the terminal occupies 18 consecutive RBs in the frequency domain and 3 symbols in the time domain. The frequency domain resources of the CORESET are indicated by a 45-bit bitmap, and the time domain resources are indicated by duration information as 3 consecutive OFDM symbols. Specifically, suppose the RB indices occupied by the CORESET within the active DL BWP are RB#0 to RB#17, and suppose the RB indices occupied by the UL subband within the active DL BWP are RB#15-RB#35, referring to... Figure 12 As shown.

[0253] In this embodiment, when there is overlap between CORESET and the first resource set, NR-PDCCH is transmitted in the following manner:

[0254] The base station removes the first PDCCH candidate that overlaps with the first resource set, that is, it does not transmit downlink control information (DL control information) on the first PDCCH candidate.

[0255] The terminal will discard the first PDCCH candidate that overlaps with the UL subband, that is, it will not detect and receive DL control information on the first PDCCH candidate.

[0256] Specifically, when the first PDCCH candidate in the NR PDCCH candidate set is mapped to an RB that overlaps with the first resource set occupied by the UL subband, the base station discards the first PDCCH candidate, that is, it does not map control information on it. The terminal also does not expect to detect and receive PDCCH candidates on the RBs that overlap with the UL subband.

[0257] Furthermore, if any RB in the first PDCCH candidate mapping overlaps with the UL subband, the base station and the terminal discard the first PDCCH candidate.

[0258] Example 3: Assuming the terminal is a Rel-18 or later version terminal, with half-duplex or full-duplex capability, this patent does not impose any limitations. It is assumed that the base station performs full-duplex operation within the downlink time slot of the TDD band, that is, simultaneously scheduling downlink and uplink data.

[0259] In this embodiment, it is assumed that the CORESET configured by the base station for the terminal overlaps with the first resource set occupied by the UL subband in the SBFD time unit. In this embodiment, the SBFD time unit specifically refers to the DL time unit or flexible time unit where the UL subband exists.

[0260] As a concrete example, suppose the CORESET configured by the base station for the terminal occupies 18 consecutive RBs in the frequency domain and 3 symbols in the time domain. The frequency domain resources of the CORESET are indicated by a 45-bit bitmap, and the time domain resources are indicated by duration information as 3 consecutive OFDM symbols. Specifically, suppose the RB indices occupied by the CORESET within the active DL BWP are RB#0 to RB#17, and suppose the RB indices occupied by the UL subband within the active DL BWP are RB#15-RB#35, referring to... Figure 12 As shown.

[0261] In this embodiment, when there is an overlap between the first resource set occupied by CORESET and UL subband, NR-PDCCH is transmitted in the following manner:

[0262] The base station offsets the CORESET on the SBFD symbol and ensures that there is no overlap between the offset CORESET and the first resource set.

[0263] The number of first RBs in the offset is configured by the base station or determined in a predefined manner.

[0264] The terminal divides the CORESET into a second resource set and a remaining resource set. According to predefined rules or indication information sent by the base station, each second resource in the second resource set is offset on the SBFD symbol to obtain a third resource set. The union of the third resource set and the remaining resource set is determined as the resource set occupied by the PDCCH.

[0265] The terminal detects and receives NR-PDCCH on the resources included in the resource set.

[0266] The number of first RBs offset by the third resource set can be configured by the base station or determined in a predefined manner.

[0267] In this embodiment, since RB#15, RB#16 and RB#17 included in CORESET overlap with the first resource set occupied by the UL subband, the corresponding 6 RBs need to be offset until they no longer overlap with the first resource set.

[0268] In this embodiment, RB#12 to RB#17 included in CORESET are determined as the third resource set and offset in the frequency domain to RB#36 to RB#41. After the offset, the RBs actually occupied by CORESET include RB#0 to RB#11 and RB#36 to RB#41. The base station maps NR PDCCH on RB#0 to RB#11 and RB#36 to RB#41, and the terminal detects and receives NR PDCCH on RB#0 to RB#11 and RB#36 to RB#41.

[0269] It is important to note that when performing RB offsets, the offsets must be performed at a granularity of 6 RBs. These offsets are only executed within SBFD time units (e.g., SBFD slots).

[0270] Example 4: Assuming the terminal is a Rel-18 or later version terminal, with half-duplex or full-duplex capability, this patent makes no limitation. It is assumed that the base station performs full-duplex operation within the downlink time slot of the TDD band, that is, simultaneously scheduling downlink and uplink data.

[0271] In this embodiment, it is assumed that the CORESET configured by the base station for the terminal overlaps with the first resource set occupied by the UL subband in the SBFD time unit. In this embodiment, the SBFD time unit specifically refers to the DL time unit or flexible time unit where the UL subband exists.

[0272] As a concrete example, suppose the CORESET configured by the base station for the terminal occupies 18 consecutive RBs in the frequency domain and 3 symbols in the time domain. The frequency domain resources of the CORESET are indicated by a 45-bit bitmap, and the time domain resources are indicated by duration information as 3 consecutive OFDM symbols. Specifically, suppose the RB indices occupied by the CORESET within the active DL BWP are RB#0 to RB#17, and suppose the RB indices occupied by the UL subband within the active DL BWP are RB#15-RB#35, referring to... Figure 12 As shown.

[0273] In this embodiment, when there is an overlap between the first resource set occupied by CORESET and UL subband, NR-PDCCH is transmitted in the following manner:

[0274] The terminal determines a new CORESET on frequency domain resources other than the first resource set.

[0275] That is, the 45-bit bitmap used to configure CORESET ignores the bandwidth occupied by the UL subband when mapping.

[0276] The base station determines the new CORESET on frequency domain resources other than the first resource set, i.e., on the actual downlink BWP.

[0277] That is, the 45-bit bitmap used to configure CORESET ignores the bandwidth occupied by the UL subband when mapping.

[0278] Specifically, based on the CORESET indication information sent by the base station, the terminal determines the specific frequency domain resource location occupied by the new CORESET on resources that do not overlap with the first resource set, for example... Figure 13 As shown.

[0279] The base station sends CORESET indication information to determine the resources occupied by the CORESET within the virtual DL BWP. Specifically, assuming the active DL BWP contains 100 RBs and a UL subband is configured within one DL slot, and the UL subband occupies RBs 15 to 35, then in this embodiment, the actual RB indices contained in the virtual DL BWP are {RB#0 to RB#14, RB#36 to RB#99}.

[0280] Assuming the base station configures the terminal with a CORESET containing 18 consecutive RBs, taking the bitmap as an example, the 45-bit bitmap is as follows:

[0281] {11100000000000000000000000000000000000000000000}.

[0282] Reference Figure 14 As shown, the base station and the terminal, in the SBFD slot, detect and receive the NR PDCCH according to the CORESET in the virtual BWP.

[0283] In the above embodiments, the transmission performance of PDCCH can be avoided, and the reliability of full-duplex communication can be improved.
