Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, apparatus, device, and medium for determining time domain resources. Background Art

[0002] To address the coverage, latency, and capacity issues of uplink and downlink transmission in Time Division Duplex (TDD) mode, research has been proposed on non-overlapping sub-band full duplex (SBFD). This involves dividing frequency resources into multiple, non-overlapping sub-bands, with the uplink and downlink frequency resources located in separate sub-bands. This is referred to as sub-band full duplex (SBFD).

[0003] The existing protocol only specifies how the terminal determines the symbol type according to all or part of the signaling in TDD-UL-DL-ConfigCommon, TDD-UL-DL-ConfigDedicated and Slot Format Indication (SFI).

[0004] However, when the base station indicates the configuration of the symbol where the uplink subband is located in addition to indicating all or part of the above-mentioned signaling, since the configuration of the symbol where the uplink subband is located is also related to the symbol, it is impossible to determine the symbol type based on the existing technology; and how the terminal determines the final symbol type is key to how to determine the time domain position of the symbol where the uplink subband is located.

[0148] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0149] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0150] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0151] In order to facilitate understanding of the solution of this application, the relevant contents involved in this application are first introduced.

[0152] In the New Radio (NR) technology version R15 to R17, the network configures the cell-level TDD configuration (cell specific TDD UL / DL configuration) through tdd-UL-DL-configurationCommon in the System Information Block 1 (SIB1), that is, the transmission direction type on the time slot / symbol symbol, including U (uplink), D (downlink), and F (flexible).

[0153] The network may also change only the F-type symbols configured at the cell level to uplink or downlink for a specific UE through tdd-UL-DL-ConfigurationDedicated (ie, TDD configuration dedicated to user equipment (UE)).

[0154] The network can also dynamically indicate the uplink and downlink directions through downlink control information (DCI) format DCIformat2_0. Similarly, DCI format2_0 can only configure the symbol indicated as F in tdd-UL-DL-configurationCommon / tdd-UL-DL-ConfigurationDedicated as uplink or downlink.

[0155] The network may semi-statically indicate the cell-level SBFD configuration, that is, indicate the configuration of the symbol where the cell-level uplink subband is located; further, it may also indicate the UE-dedicated SBFD configuration, that is, indicate the configuration of the symbol where the UE-dedicated uplink subband is located.

[0156] The prior art only specifies a method for the terminal to determine the symbol type based on all or part of the signaling in tdd-UL-DL-ConfigCommon, tdd-UL-DL-ConfigDedicated, and SFI (changes in the uplink and downlink time slot formats can be indicated through DCI). When the network-side device indicates the SBFD configuration in addition to all or part of the above signaling, the configuration of the symbol where the uplink subband is located is also related to the symbol. Therefore, the symbol type cannot be determined based on the prior art. The key to how the terminal determines the final symbol type lies in how to determine the time domain position of the symbol where the uplink subband is located. Therefore, how to determine the time domain position of the symbol where the uplink subband is located is a technical problem that needs to be solved.

[0157] In order to solve the above technical problems, the embodiments of the present application provide a time domain resource determination method, device, equipment and medium, wherein the method and device are based on the same application concept. Since the principles of solving the problems by the method and device are similar, the implementation of the device and method can refer to each other, and the repeated parts will not be repeated.

[0158] like Figure 1 FIG. 1 is a flow chart of a method for determining time domain resources according to an embodiment of the present application, wherein the method is applied to a terminal, that is, the method is executed by the terminal. The method may include:

[0159] Step 101: Receive a first configuration and a second configuration sent by a network-side device, where the first configuration indicates a configuration of a first symbol, where the first symbol is a symbol where an uplink subband is located; and the second configuration indicates a configuration of a second symbol, where the second symbol is an uplink symbol, a downlink symbol, and / or a flexible symbol.

[0160] Optionally, the first configuration includes a cell-level configuration of a first symbol and / or a UE-specific configuration of a first symbol.

[0161] Optionally, the second configuration includes one or more of the following configurations:

[0162] TDD configuration at the cell level;

[0163] Semi-static UE-specific TDD configuration;

[0164] SFI.

[0165] Step 102: Determine a time domain position of a first symbol according to the first configuration and the second configuration.

[0166] In some embodiments, the first configuration includes a cell-level configuration of a first symbol; the second configuration includes a cell-level time division duplex (TDD) configuration and a semi-static UE-specific TDD configuration;

[0167] Here, the cell-level TDD configuration is the configuration indicated by TDD-UL-DL-ConfigCommon signaling; and the UE-specific TDD configuration is the configuration indicated by TDD-UL-DL-ConfigDedicated signaling.

[0168] That is, the UE does not support the configuration of the UE-specific first symbol, or the network-side device has not configured the configuration of the UE-specific first symbol, or the UE has not received the configuration of the UE-specific first symbol.

[0169] Accordingly, step 102, determining the time domain position of the first symbol according to the first configuration and the second configuration, includes:

[0170] a1. Determine a time domain position of the first symbol according to the cell-level configuration of the first symbol and the cell-level TDD configuration, wherein a semi-static UE-specific TDD configuration is not supported or the terminal does not expect to change the time domain position of the first symbol;

[0171] Here, not supporting or not expecting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol by the terminal can be understood as the terminal receiving the semi-static UE-specific TDD configuration sent by the network-side device, but the semi-static UE-specific TDD configuration cannot cover the configuration of the first symbol determined according to the cell-level configuration of the first symbol; or not supporting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol can be understood as: if the UE-specific TDD configuration indicates that the configuration of the first symbol determined according to the cell-level configuration of the first symbol is covered, the UE ignores the configuration. It should be understood that the meaning of not being able to cover means that the configuration of other signaling cannot be canceled or changed.

[0172] As an optional embodiment, the cell-level first symbol configuration indicates a first target position of the first symbol within a TDD configuration period, and the cell-level TDD configuration indicates a TDD configuration period; accordingly, step a1, determining the time domain position of the first symbol according to the cell-level first symbol configuration and the cell-level TDD configuration, includes:

[0173] A time domain position of the first symbol is determined according to a first target position of the first symbol within a TDD configuration period and the TDD configuration period.

[0174] It should be noted that the time domain position of the first symbol is repeated periodically with the TDD configuration period. Optionally, the symbol type corresponding to the first target position in the cell-level TDD configuration is a downlink symbol and / or a flexible symbol.

[0175] That is, the configuration of the first symbol at the cell level can override the cell-level TDD configuration indication as a downlink symbol or a flexible symbol whose symbol type is the first symbol. It should be understood that the meaning of overriding is to partially or completely cancel the configuration of other signaling, or partially or completely replace the configuration of other signaling, or to update part or all of the configuration of other signaling with the configuration of its own signaling.

[0176] In one example, the TDD-UL-DL-ConfigCommon signaling (cell-level TDD configuration) is {D,D,D,F,U,D,D,D,F,U}, where D represents a downlink time slot, F represents a flexible time slot, and U represents an uplink time slot. The cell-level configuration of the first symbol indicates that the time domain position of the symbol where the subband is located is the time slot with index 1 to 3, where the time slot numbering starts from index = 0. Then the symbol type determined by the UE based on the TDD-UL-DL-ConfigCommon signaling and the cell-level configuration of the first symbol is {D,X,X,X,U,D,D,D,F,U}, where X represents the time domain position of the symbol where the subband is located. In this case, the symbol type of the symbol at X is the first symbol.

[0177] Alternatively, a2: determine the time domain position of the first symbol according to the cell-level configuration of the first symbol, the cell-level TDD configuration, and the semi-static UE-specific TDD configuration.

[0178] As an optional embodiment, the cell-level configuration of the first symbol indicates a first target position of the first symbol within a TDD configuration period, the cell-level TDD configuration indicates a TDD configuration period, and the semi-static UE-specific TDD configuration is used to indicate that the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F; and / or, the semi-static UE-specific TDD configuration indicates that the symbol at the fifth target position is a downlink symbol D;

[0179] Correspondingly, step a2, determining the time domain position of the first symbol according to the cell-level configuration of the first symbol, the cell-level TDD configuration, and the semi-static UE-specific TDD configuration, includes:

[0180] a21, determining a third target position according to a first target position of the first symbol in the TDD configuration period and the TDD configuration period;

[0181] Here, the third target position is the position of the first symbol in the TDD configuration period. The third target position is repeated with the TDD configuration period as a period.

[0182] a22. Determine, based on the semi-static UE-specific TDD configuration, a symbol type of the symbol at the fourth target position as a downlink symbol D, an uplink symbol U, or a flexible symbol F; determine that other time domain positions of the third target position except the fourth target position are time domain positions of the first symbol within the TDD configuration period, and determine a time domain position obtained by periodically repeating the time domain position of the first symbol within the TDD configuration period according to the TDD configuration period as the time domain position of the first symbol;

[0183] The fourth target position includes the third target position configured at a sixth target position, and the sixth target position is a time domain position where the cell-level TDD configuration indicates a flexible symbol.

[0184] It should be understood that, according to the semi-static UE-specific TDD configuration, the symbol type of the symbol at the third target position configured at the time domain position where the cell-level TDD configuration indication is the flexible symbol F is determined to be D, U or F.

[0185] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as F by TDD-UL-DL-ConfigCommon as D, U or F.

[0186] For example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the configuration of the first symbol at the cell level indicates that the time domain position of the symbol in the subband is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X3 position is the position where TDD-UL-DL-ConfigCommon indicates F, according to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X3 position from the first symbol to D, U or F. The symbol type determined in this way is {D,X1,X2,(D / U / F),U,D,D,D,F,U}, then the time domain position of the first symbol is the X1 position and the X2 position.

[0187] Alternatively, a23, according to the semi-static UE-specific TDD configuration, determine that the symbol type of the symbol at the fifth target position is a downlink symbol D; and determine that the other time domain positions of the third target position except the fifth target position are the time domain positions of the first symbol within the TDD configuration period, and determine the time domain position of the first symbol within the TDD configuration period after periodic repetition according to the TDD configuration period as the time domain position of the first symbol;

[0188] The fifth target position includes the third target position configured at the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0189] It should be understood that, according to the semi-static UE-specific TDD configuration, it is determined that the symbol type of the symbol at the third target position configured at the time domain position of the downlink symbol D indicated by the cell-level TDD configuration is D.

[0190] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as D by TDD-UL-DL-ConfigCommon as D, but cannot cover it as U.

[0191] In one example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the configuration of the first symbol at the cell level indicates that the time domain position of the symbol in the subband is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X1 position and the X2 position are the positions indicated as D by TDD-UL-DL-ConfigCommon, according to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X1 position from the first symbol to D. The symbol type determined in this way can be {D,D,X2,X3,U,D,D,D,F,U}, then the time domain position of the first symbol is the X2 and X3 positions.

[0192] Alternatively, a24, according to the semi-static UE-specific TDD configuration, determine that the symbol type of the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F, and determine that the symbol type of the symbol at the fifth target position is a downlink symbol D, and determine that the other time domain positions of the third target position except the fourth target position and the fifth target position are the time domain positions of the first symbol within the TDD configuration period, and determine the time domain position obtained after periodically repeating the time domain position of the first symbol within the TDD configuration period according to the TDD configuration period as the time domain position of the first symbol;

[0193] Among them, the fourth target position includes the third target position configured on the sixth target position, the sixth target position is the time domain position of the flexible symbol indicated by the cell-level TDD configuration, and the fifth target position includes the third target position configured on the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0194] It should be understood that according to the semi-static UE-specific TDD configuration, the symbol type of the symbol at the third target position on the time domain position where the TDD configuration indication configured at the cell level is the flexible symbol F is determined to be D, U or F; and the symbol type of the symbol at the third target position on the time domain position where the TDD configuration indication configured at the cell level is the downlink symbol D is determined to be D.

[0195] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as F by TDD-UL-DL-ConfigCommon as D, U or F, and can also cover the cell-level first symbol at the position indicated as D by TDD-UL-DL-ConfigCommon as D, but it cannot be covered as U.

[0196] For example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the time domain position of the symbol where the configuration indication subband of the first symbol at the cell level is located is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X3 position is TDD-UL-DL-Conf The position indicated by igCommon is F. According to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X3 position from the first symbol to D, U or F. The X2 position is the position indicated by TDD-UL-DL-ConfigCommon as D. According to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X2 position from the first symbol to D. The final determined symbol type is {D,X1,D,(D / U / F),U,D,D,D,F,U}, then the time domain position of the first symbol is the X1 position.

[0197] It should be noted that the above a21 and a22 are combined into one solution, a21 and a23 are combined into one solution, and a21 and a24 are combined into one solution, that is, three parallel solutions.

[0198] In some embodiments, the first configuration includes a cell-level first symbol configuration and a UE-specific first symbol configuration; the second configuration includes a cell-level TDD configuration;

[0199] That is, the UE supports and receives the UE-specific first symbol configuration, but the network-side device is not configured with the semi-static UE-specific TDD configuration or the UE does not receive the semi-static UE-specific TDD configuration.

[0200] Accordingly, the above step 102, determining the time domain position of the first symbol according to the first configuration and the second configuration, includes:

[0201] b1, determining a time domain position of the first symbol according to a configuration of the UE-specific first symbol and the cell-level TDD configuration;

[0202] In this solution, the cell-level first symbol configuration is not used because the UE-specific first symbol configuration overrides / changes the cell-level first symbol configuration. The UE no longer determines the time domain position of the first symbol based on the cell-level first symbol configuration.

[0203] As an optional embodiment, the configuration of the UE-specific first symbol indicates a second target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates the TDD configuration period; accordingly, step b1, determining the time domain position of the first symbol according to the configuration of the UE-specific first symbol and the cell-level TDD configuration, includes:

[0204] The time domain position of the first symbol is determined according to a second target position of the first symbol within the TDD configuration period and the TDD configuration period.

[0205] It should be noted that the time domain position of the first symbol is repeated periodically with the TDD configuration period. Optionally, the second target position is at a time domain position where the cell-level TDD configuration indicates a downlink symbol and / or a flexible symbol. In other words, the symbol type corresponding to the second target position in the cell-level TDD configuration is a downlink symbol and / or a flexible symbol.

[0206] That is, the configuration of the first symbol at the cell level can cover the TDD configuration indication at the cell level, which indicates that the symbol type of the downlink symbol or the flexible symbol is the first symbol.

[0207] In one example, the TDD-UL-DL-ConfigCommon signaling (cell-level TDD configuration) is {D,D,D,F,U,D,D,D,F,U}, where D represents a downlink time slot, F represents a flexible time slot, and U represents an uplink time slot. The configuration of the UE-specific first symbol indicates that the time domain position of the symbol where the subband is located is the time slot with index 1 to 3, where the time slot numbering starts from index = 0. Then the symbol type determined by the UE based on the TDD-UL-DL-ConfigCommon signaling and the UE-specific configuration of the first symbol is {D,X,X,X,U,D,D,D,F,U}, where X represents the time domain position of the symbol where the subband is located. In this case, the symbol type of the symbol at X is the first symbol.

[0208] Alternatively, b2: determining the time domain position of the first symbol according to the configuration of the cell-level first symbol, the configuration of the UE-specific first symbol, and the cell-level TDD configuration.

[0209] As an optional embodiment, the configuration of the cell-level first symbol indicates a first target position of the first symbol within the TDD configuration period, the configuration of the UE-specific first symbol indicates a second target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates a TDD configuration period; accordingly, step b2, determining the time domain position of the first symbol according to the cell-level first symbol configuration, the UE-specific first symbol configuration, and the cell-level TDD configuration, includes:

[0210] Determine the position of the first symbol in the first target position within the TDD configuration period, excluding the second target position, as the time domain position of the first symbol within the TDD configuration period; determine the time domain position obtained after periodically repeating the time domain position of the first symbol within the TDD configuration period according to the TDD configuration period as the time domain position of the first symbol.

[0211] Under this scheme, the configuration of the UE-specific first symbol is used to cancel the configuration of the first symbol at the second target position, so the time domain position of the first symbol within the TDD configuration period is a position in the first target position except the second target position.

[0212] Alternatively, the first target position and the second target position are determined to be the time domain position of the first symbol within the TDD configuration period; the time domain position of the first symbol within the TDD configuration period is obtained by periodically repeating the time domain position according to the TDD configuration period as the time domain position of the first symbol.

[0213] This embodiment is a partial coverage / change of the configuration of the UE-specific first symbol within the TDD configuration period.

[0214] As another optional embodiment, the configuration of the cell-level first symbol indicates a first target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates the TDD configuration period; accordingly, step b2, determining the time domain position of the first symbol according to the cell-level first symbol configuration, the UE-specific first symbol configuration, and the cell-level TDD configuration, includes:

[0215] (1) determining a third target position according to a first target position of the first symbol within a TDD configuration period and the TDD configuration period;

[0216] Here, the third target position is the position of the first symbol in the TDD configuration period. The third target position is repeated with the TDD configuration period as a period.

[0217] (2) determining one or more TDD configuration periods in which a third target position is valid based on the configuration of the UE-specific first symbol; and determining the time domain position of the first symbol based on the third target position and the one or more TDD configuration periods in which the third target position is valid, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position is valid over multiple TDD configuration periods;

[0218] It should be noted that the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit and multiple TDD configuration periods as indication periods, that is, the configuration of the UE-specific first symbol is repeated with multiple TDD configuration periods as a period.

[0219] Here, the third target position is repeated with the TDD configuration period as a period, indicating that there is a third target position in each TDD configuration period. Here, the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid. In other words, there is a third target position in each TDD configuration period, but which TDD configuration period the third target position is valid is indicated by the configuration of the UE-specific first symbol. The time domain position of the first symbol is determined by the third target position in one or more valid TDD configuration periods.

[0220] Alternatively, (3) determining one or more TDD configuration periods in which the third target position is valid and / or invalid based on the configuration of the UE-specific first symbol; determining the first time domain position of the first symbol on the one or more TDD configuration periods in which the third target position is valid based on the third target position and the one or more TDD configuration periods in which the third target position is valid; and / or determining the second time domain position of the first symbol on the one or more TDD configuration periods in which the third target position is invalid based on the one or more TDD configuration periods in which the third target position is invalid and the first symbol configuration information within the one or more TDD configuration periods in which the third target position is invalid; and determining the time domain position of the first symbol based on the first time domain position and the second time domain position, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid, and the configuration of the UE-specific first symbol indicates the first symbol configuration information within the one or more TDD configuration periods in which the third target position is invalid.

[0221] Here, the configuration of the UE-specific first symbol not only uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid, but also indicates the first symbol configuration information in one or more TDD configuration periods in which the third target position is invalid.

[0222] Here, the third target position is repeated with the TDD configuration period as a period, which means that there is a third target position in each TDD configuration period.

[0223] It should be noted that when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is valid, after determining the one or more TDD configuration periods in which the third target position is valid according to the configuration of the UE-specific first symbol, one or more TDD configuration periods in which the third target position is invalid are indirectly determined; when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is invalid, after determining the one or more TDD configuration periods in which the third target position is invalid according to the configuration of the UE-specific first symbol, one or more TDD configuration periods in which the third target position is valid are indirectly determined; when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is valid and invalid, one or more TDD configuration periods in which the third target position is valid and invalid are directly determined according to the configuration of the UE-specific first symbol. Afterwards, the first time domain position of the first symbol is determined based on the third target position within one or more valid TDD configuration periods, and / or the second time domain position of the first symbol is determined based on the first symbol configuration information within one or more invalid TDD configuration periods and one or more TDD configuration periods indicating that the third target position is invalid; the first time domain position and the second time domain position of the first symbol are the time domain position of the first symbol.

[0224] In this embodiment, the configuration of the UE-specific first symbol cancels or changes the configuration of the first symbol in part or all of the TDD configuration periods.

[0225] In some embodiments, the first configuration includes a cell-level first symbol configuration and a UE-specific first symbol configuration; the second configuration includes a cell-level TDD configuration and a semi-static UE-specific TDD configuration;

[0226] That is, the UE supports and receives the UE-specific first symbol configuration and the semi-static UE-specific TDD configuration.

[0227] Accordingly, the above step 102, determining the time domain position of the first symbol according to the first configuration and the second configuration, includes:

[0228] c1. Determine a time domain position of the first symbol according to the configuration of the UE-specific first symbol and the cell-level TDD configuration, wherein the semi-static UE-specific TDD configuration is not supported or the terminal does not expect the time domain position of the first symbol to be changed;

[0229] In this solution, the reason why the cell-level configuration of the first symbol is not utilized is that the UE-specific configuration of the first symbol overrides / changes the cell-level configuration of the first symbol, and the UE no longer determines the time domain position of the first symbol based on the cell-level configuration of the first symbol. Here, not supporting or the terminal not expecting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol can be understood as the terminal receiving the semi-static UE-specific TDD configuration sent by the network-side device, but the semi-static UE-specific TDD configuration cannot override the configuration of the first symbol determined according to the UE-specific configuration of the first symbol; or, not supporting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol can be understood as: if the UE-specific TDD configuration indicates that the configuration of the first symbol determined according to the UE-specific configuration of the first symbol is overwritten, the UE ignores the configuration.

[0230] As an optional embodiment, the configuration of the UE-specific first symbol indicates a second target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates the TDD configuration period; accordingly, step c1, determining the time domain position of the first symbol according to the configuration of the UE-specific first symbol and the cell-level TDD configuration, includes:

[0231] The time domain position of the first symbol is determined according to a second target position of the first symbol within the TDD configuration period and the TDD configuration period.

[0232] It should be noted that the time domain position of the first symbol is repeated periodically with the TDD configuration period. Optionally, the second target position is at a time domain position where the cell-level TDD configuration indicates a downlink symbol and / or a flexible symbol. In other words, the symbol type corresponding to the second target position in the cell-level TDD configuration is a downlink symbol and / or a flexible symbol.

[0233] In one example, the TDD-UL-DL-ConfigCommon signaling (cell-level TDD configuration) is {D,D,D,F,U,D,D,D,F,U}, where D represents a downlink time slot, F represents a flexible time slot, and U represents an uplink time slot. The configuration of the UE-specific first symbol indicates that the time domain position of the symbol where the subband is located is the time slot with index 1 to 3, where the time slot numbering starts from index = 0. Then the symbol type determined by the UE based on the TDD-UL-DL-ConfigCommon signaling and the UE-specific configuration of the first symbol is {D,X,X,X,U,D,D,D,F,U}, where X represents the time domain position of the symbol where the subband is located. In this case, the symbol type of the symbol at X is the first symbol.

[0234] Alternatively, c2: determining a time domain position of the first symbol according to the cell-level configuration of the first symbol, the UE-specific configuration of the first symbol, and the cell-level TDD configuration, wherein the semi-static UE-specific TDD configuration is not supported or the terminal does not expect the time domain position of the first symbol to be changed;

[0235] Here, not supporting or expecting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol can be understood as the terminal receiving the semi-static UE-specific TDD configuration sent by the network side device, but the semi-static UE-specific TDD configuration cannot cover the configuration of the first symbol determined according to the cell-level first symbol configuration and the UE-specific first symbol configuration; or not supporting or expecting the semi-static UE-specific TDD configuration to change the time domain position of the first symbol can be understood as: if the UE-specific TDD configuration indicates coverage of the configuration of the first symbol determined according to the cell-level first symbol configuration and the UE-specific first symbol configuration, the UE ignores the configuration.

[0236] As an optional embodiment, the configuration of the cell-level first symbol indicates a first target position of the first symbol within the TDD configuration period, the configuration of the UE-specific first symbol indicates a second target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates a TDD configuration period; accordingly, step c2, determining the time domain position of the first symbol according to the cell-level first symbol configuration, the UE-specific first symbol configuration, and the cell-level TDD configuration, includes:

[0237] Determine the position of the first symbol in the first target position within the TDD configuration period, excluding the second target position, as the time domain position of the first symbol within the TDD configuration period; determine the time domain position obtained after periodically repeating the time domain position of the first symbol within the TDD configuration period according to the TDD configuration period as the time domain position of the first symbol.

[0238] Under this scheme, the configuration of the UE-specific first symbol is used to cancel the configuration of the first symbol at the second target position, so the time domain position of the first symbol within the TDD configuration period is a position in the first target position except the second target position.

[0239] Alternatively, the first target position and the second target position are determined to be the time domain position of the first symbol within the TDD configuration period; the time domain position of the first symbol within the TDD configuration period is obtained by periodically repeating the time domain position according to the TDD configuration period as the time domain position of the first symbol.

[0240] This embodiment is a partial coverage / change of the configuration of the UE-specific first symbol within the TDD configuration period.

[0241] As another optional embodiment, the configuration of the cell-level first symbol indicates a first target position of the first symbol within the TDD configuration period, and the cell-level TDD configuration indicates the TDD configuration period; accordingly, step c2, determining the time domain position of the first symbol according to the cell-level first symbol configuration, the UE-specific first symbol configuration, and the cell-level TDD configuration, includes:

[0242] (1) determining a third target position according to a first target position of the first symbol within a TDD configuration period and the TDD configuration period;

[0243] Here, the third target position is the position of the first symbol in the TDD configuration period. The third target position is repeated with the TDD configuration period as a period.

[0244] (2) determining one or more TDD configuration periods in which a third target position is valid based on the configuration of the UE-specific first symbol; and determining the time domain position of the first symbol based on the third target position and the one or more TDD configuration periods in which the third target position is valid, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position is valid over multiple TDD configuration periods;

[0245] It should be noted that the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit and multiple TDD configuration periods as indication periods, that is, the configuration of the UE-specific first symbol is repeated with multiple TDD configuration periods as a period.

[0246] Here, the third target position is repeated with the TDD configuration period as a period, indicating that there is a third target position in each TDD configuration period. Here, the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid. In other words, there is a third target position in each TDD configuration period, but which TDD configuration period the third target position is valid is indicated by the configuration of the UE-specific first symbol. The time domain position of the first symbol is determined by the third target position in one or more valid TDD configuration periods.

[0247] Alternatively, (3) determining one or more TDD configuration periods in which the third target position is valid and / or invalid based on the configuration of the UE-specific first symbol; determining the first time domain position of the first symbol on the one or more TDD configuration periods in which the third target position is valid based on the third target position and the one or more TDD configuration periods in which the third target position is valid; and / or determining the second time domain position of the first symbol on the one or more TDD configuration periods in which the third target position is invalid based on the one or more TDD configuration periods in which the third target position is invalid and the first symbol configuration information within the one or more TDD configuration periods in which the third target position is invalid; and determining the time domain position of the first symbol based on the first time domain position and the second time domain position, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid, and the configuration of the UE-specific first symbol indicates the first symbol configuration information within the one or more TDD configuration periods in which the third target position is invalid.

[0248] Here, the configuration of the UE-specific first symbol not only uses the TDD configuration period as an indication unit to indicate whether the third target position on multiple TDD configuration periods is valid, but also indicates the first symbol configuration information in one or more TDD configuration periods in which the third target position is invalid.

[0249] Here, the third target position is repeated with the TDD configuration period as a period, which means that there is a third target position in each TDD configuration period.

[0250] It should be noted that when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is valid, after determining the one or more TDD configuration periods in which the third target position is valid according to the configuration of the UE-specific first symbol, one or more TDD configuration periods in which the third target position is invalid are indirectly determined; when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is invalid, after determining the one or more TDD configuration periods in which the third target position is invalid according to the configuration of the UE-specific first symbol, one or more TDD configuration periods in which the third target position is valid are indirectly determined; when the configuration of the UE-specific first symbol indicates one or more TDD configuration periods in which the third target position is valid and invalid, one or more TDD configuration periods in which the third target position is valid and invalid are directly determined according to the configuration of the UE-specific first symbol. Afterwards, the first time domain position of the first symbol is determined based on the third target position within one or more valid TDD configuration periods, and / or the second time domain position of the first symbol is determined based on the first symbol configuration information within one or more invalid TDD configuration periods and one or more TDD configuration periods indicating that the third target position is invalid; the first time domain position and the second time domain position of the first symbol are the time domain position of the first symbol.

[0251] In this embodiment, the configuration of the UE-specific first symbol cancels or changes the configuration of the first symbol in part or all of the TDD configuration periods.

[0252] Alternatively, c3, determining a time domain position of the first symbol according to a cell-level configuration of the first symbol, a cell-level TDD configuration, and the semi-static UE-specific TDD configuration;

[0253] Here, the terminal ignores or interprets the configuration of the UE-specific first symbol.

[0254] As an optional embodiment, the cell-level configuration of the first symbol indicates a first target position of the first symbol within a TDD configuration period, the cell-level TDD configuration indicates a TDD configuration period, and the semi-static UE-specific TDD configuration is used to indicate that the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F; and / or, the semi-static UE-specific TDD configuration indicates that the symbol at the fifth target position is a downlink symbol D;

[0255] Correspondingly, step c3, determining the time domain position of the first symbol according to the cell-level configuration of the first symbol, the cell-level TDD configuration, and the semi-static UE-specific TDD configuration, includes:

[0256] c31, determining a third target position according to a first target position of the first symbol in the TDD configuration period and the TDD configuration period;

[0257] Here, the third target position is the position of the first symbol in the TDD configuration period. The third target position is repeated with the TDD configuration period as a period.

[0258] c32. Determine, based on the semi-static UE-specific TDD configuration, the symbol type of the symbol at the fourth target position as a downlink symbol D, an uplink symbol U, or a flexible symbol F; determine that the other time domain positions of the third target position except the fourth target position are the time domain positions of the first symbol within the TDD configuration period, and determine the time domain position of the first symbol within the TDD configuration period after periodically repeating the time domain position according to the TDD configuration period as the time domain position of the first symbol;

[0259] The fourth target position includes the third target position configured at a sixth target position, and the sixth target position is a time domain position where the cell-level TDD configuration indicates a flexible symbol.

[0260] It should be understood that, according to the semi-static UE-specific TDD configuration, the symbol type of the symbol at the third target position configured at the time domain position where the cell-level TDD configuration indication is the flexible symbol F is determined to be D, U or F.

[0261] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as F by TDD-UL-DL-ConfigCommon as D, U or F.

[0262] For example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the configuration of the first symbol at the cell level indicates that the time domain position of the symbol in the subband is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X3 position is the position where TDD-UL-DL-ConfigCommon indicates F, according to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X3 position from the first symbol to D, U or F. The symbol type determined in this way is {D,X1,X2,(D / U / F),U,D,D,D,F,U}, then the time domain position of the first symbol is the X1 position and the X2 position.

[0263] Alternatively, c33, according to the semi-static UE-specific TDD configuration, determines that the symbol type of the symbol at the fifth target position is a downlink symbol D; and determines that the other time domain positions of the third target position except the fifth target position are the time domain positions of the first symbol within the TDD configuration period, and determines the time domain position of the first symbol within the TDD configuration period after periodic repetition according to the TDD configuration period as the time domain position of the first symbol;

[0264] The fifth target position includes the third target position configured at the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0265] It should be understood that, according to the semi-static UE-specific TDD configuration, it is determined that the symbol type of the symbol at the third target position configured at the time domain position of the downlink symbol D indicated by the cell-level TDD configuration is D.

[0266] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as D by TDD-UL-DL-ConfigCommon as D, but cannot cover it as U.

[0267] For example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the configuration of the first symbol at the cell level indicates that the time domain position of the symbol in the subband is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X1 position and the X2 position are the positions indicated as D by TDD-UL-DL-ConfigCommon, according to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X1 position from the first symbol to D. The symbol type determined in this way can be {D,D,X2,X3,U,D,D,D,F,U}, then the time domain position of the first symbol is the X2 and X3 positions.

[0268] Alternatively, c34, according to the semi-static UE-specific TDD configuration, determines that the symbol type of the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F, and determines that the symbol type of the symbol at the fifth target position is a downlink symbol D, and determines that the other time domain positions of the third target position except the fourth target position and the fifth target position are the time domain positions of the first symbol within the TDD configuration period, and determines the time domain position obtained after periodically repeating the time domain position of the first symbol within the TDD configuration period according to the TDD configuration period as the time domain position of the first symbol;

[0269] Among them, the fourth target position includes the third target position configured on the sixth target position, the sixth target position is the time domain position of the flexible symbol indicated by the cell-level TDD configuration, and the fifth target position includes the third target position configured on the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0270] It should be understood that according to the semi-static UE-specific TDD configuration, the symbol type of the symbol at the third target position on the time domain position where the TDD configuration indication configured at the cell level is the flexible symbol F is determined to be D, U or F; and the symbol type of the symbol at the third target position on the time domain position where the TDD configuration indication configured at the cell level is the downlink symbol D is determined to be D.

[0271] That is, the semi-static UE-specific TDD configuration (configuration indicated by TDD-UL-DL-ConfigDedicated signaling) can cover the cell-level first symbol at the position indicated as F by TDD-UL-DL-ConfigCommon as D, U or F, and can also cover the cell-level first symbol at the position indicated as D by TDD-UL-DL-ConfigCommon as D, but it cannot be covered as U.

[0272] For example, the TDD-UL-DL-ConfigCommon signaling is {D,D,D,F,U,D,D,D,F,U}, and the time domain position of the symbol where the configuration indication subband of the first symbol at the cell level is located is the time slot with index 1 to 3, where the time slot number starts from index = 0, that is, the symbol type determined by the UE according to the TDD-UL-DL-ConfigCommon signaling and the configuration of the first symbol at the cell level is {D,X1,X2,X3,U,D,D,D,F,U}. Since the X3 position is TDD-UL-DL-Conf The position indicated by igCommon is F. According to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X3 position from the first symbol to D, U or F. The X2 position is the position indicated by TDD-UL-DL-ConfigCommon as D. According to the above rules, the semi-static UE-specific TDD configuration can change the symbol type of the symbol at the X2 position from the first symbol to D. The final determined symbol type is {D,X1,D,(D / U / F),U,D,D,D,F,U}, then the time domain position of the first symbol is the X1 position.

[0273] It should be noted that the above c31 and c32 are combined into one solution, c31 and c33 are combined into one solution, and c31 and c34 are combined into one solution, that is, three parallel solutions.

[0274] Alternatively, c4, determine the time domain position of the first symbol according to the cell-level first symbol configuration, the UE-specific first symbol configuration, the cell-level TDD configuration and the semi-static UE-specific TDD configuration.

[0275] As an optional embodiment, the cell-level configuration of the first symbol indicates a first target position of the first symbol within a TDD configuration period, the cell-level TDD configuration indicates a TDD configuration period, and the semi-static UE-specific TDD configuration is used to indicate that the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F; and / or the semi-static UE-specific TDD configuration indicates that the symbol at the fifth target position is a downlink symbol D; accordingly, step c4 includes:

[0276] c41, determining a third target position according to a first target position of the first symbol in the TDD configuration period and the TDD configuration period;

[0277] Here, the third target position is the position of the first symbol in the TDD configuration period. The third target position is repeated with the TDD configuration period as a period.

[0278] c42, according to the semi-static UE-specific TDD configuration, determining that the symbol type of the symbol at the fourth target position is a downlink symbol D, an uplink symbol U, or a flexible symbol F; and determining that the other time domain positions of the third target position except the fourth target position are the time domain positions of the first symbol within the TDD configuration period; wherein the fourth target position includes the third target position configured at the sixth target position, and the sixth target position is the time domain position of the flexible symbol indicated by the cell-level TDD configuration.

[0279] Alternatively, c43, based on the semi-static UE-specific TDD configuration, determines that the symbol type of the symbol at the fifth target position is a downlink symbol D; and determines that the other time domain positions of the third target position except the fifth target position are the time domain positions of the first symbol within the TDD configuration period; wherein the fifth target position includes the third target position configured at the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0280] Alternatively, c44, based on the semi-static UE-specific TDD configuration, determines that the symbol type of the symbol at the fourth target position is a downlink symbol D, an uplink symbol U or a flexible symbol F, and determines that the symbol type of the symbol at the fifth target position is a downlink symbol D, and determines that the other time domain positions of the third target position except the fourth target position and the fifth target position are the time domain positions of the first symbol within the TDD configuration period; wherein the fourth target position includes the third target position configured at the sixth target position, the sixth target position is the time domain position of the flexible symbol indicated by the cell-level TDD configuration, and the fifth target position includes the third target position configured at the seventh target position, and the seventh target position is the time domain position of the downlink symbol indicated by the cell-level TDD configuration.

[0281] For the detailed description of the aforementioned parts c41 to c44, please refer to the aforementioned steps c31 to c34, which will not be repeated here.

[0282] c45. Determine, based on the configuration of the UE-specific first symbol, one or more TDD configuration periods in which a first position is valid, where the first position is a time domain position of the first symbol within the TDD configuration period, and determine the time domain position of the first symbol based on the first position and the one or more TDD configuration periods in which the first position is valid, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the first position over multiple TDD configuration periods is valid;

[0283] It should be noted that, for any of the above-mentioned schemes c42 to c44, the time domain position of the first symbol determined based on the third target position within the TDD configuration period is invalid if the corresponding TDD configuration period is invalid. The time domain position of the determined first symbol is valid only when the corresponding TDD configuration period is valid.

[0284] For the above content, a more popular understanding is that the configuration of the UE-specific first symbol can cancel the configuration of the time domain position of the first symbol within the TDD configuration period determined according to the cell-level first symbol configuration and the semi-static UE-specific TDD configuration in one or more TDD configuration periods, that is, the configuration on the one or more TDD configuration periods is not effective.

[0285] Alternatively, c46, determines one or more TDD configuration periods in which the first position is valid and / or invalid based on the configuration of the UE-specific first symbol, the first position being the time domain position of the first symbol within the TDD configuration period, and determines the first time domain position of the first symbol on the one or more TDD configuration periods in which the first position is valid based on the first position and the one or more TDD configuration periods in which the first position is valid, and / or determines the second time domain position of the first symbol on the one or more TDD configuration periods in which the first position is invalid based on the one or more TDD configuration periods in which the first position is invalid and the first symbol configuration information within the one or more TDD configuration periods in which the first position is invalid, and determines the time domain position of the first symbol based on the first time domain position and the second time domain position, wherein the configuration of the UE-specific first symbol uses the TDD configuration period as an indication unit to indicate whether the first position on multiple TDD configuration periods is valid, and the configuration of the UE-specific first symbol indicates the first symbol configuration information within the one or more TDD configuration periods in which the first position is invalid.

[0286] It should be noted that, for any of the above-mentioned schemes c42 to c44, the time domain position of the first symbol within the TDD configuration period determined based on the third target position is determined. If the corresponding TDD configuration period is valid, the time domain position of the first symbol within the TDD configuration period is determined to be valid, and the first time domain position of the first symbol is determined based on the first position (the time domain position of the first symbol within the TDD configuration period) and one or more TDD configuration periods in which the first position is valid; if the corresponding TDD configuration period is invalid, it is necessary to further determine the second time domain position of the first symbol based on the first symbol configuration information within the TDD configuration period in which the first position is invalid and one or more TDD configuration periods in which the first position is invalid; finally, the first time domain position and the second time domain position of the first symbol are the time domain position of the first symbol.

[0287] Optionally, the UE first determines the third target position based on the first target position of the first symbol within the TDD configuration period and the TDD configuration period; then, determines one or more valid / invalid TDD configuration periods based on the UE-specific first symbol configuration; finally, for the one or more TDD configuration periods in which the third target position is valid, further determines the time domain position of the first symbol within the one or more valid TDD configuration periods based on the semi-static UE-specific TDD configuration.

[0289] For the above content, a more popular understanding is that the configuration of the UE-specific first symbol can change the configuration of the cell-level first symbol on one or more TDD configuration periods, and the symbol type on the one or more TDD configuration periods is determined according to the configuration of the UE-specific first symbol, that is, the configuration of the UE-specific first symbol covers the configuration of the cell-level first symbol on one or more TDD configuration periods.

[0290] Optionally, the first configuration includes a cell-level configuration of a first symbol and / or a UE-specific configuration of a first symbol; the second configuration includes time slot format indication information SFI, wherein the SFI is not supported or the terminal does not expect the configuration of the first symbol to be changed.
