[0044] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first given.

[0045] (1) Sub-Band Full Duplex (SBFD), which can also be described as flexible duplex;

[0046] When deploying traditional cellular networks, frequency division duplex (FDD) or time division duplex (TDD) can be used, depending on the available spectrum and service characteristics. In FDD, uplink and downlink transmissions occur on different frequencies, preventing interference and allowing simultaneous transmission. In TDD, uplink and downlink transmissions occur on the same frequency, interleaved using time division duplexing. Each duplexing method has its own advantages and disadvantages.

[0047] In order to more flexibly utilize limited spectrum resources, dynamically match service needs, improve resource utilization efficiency, and enhance uplink coverage, latency, and other performance of data transmission, flexible duplexing methods are proposed. A flexible duplexing method based on non-overlapping sub-bands in the frequency domain (non-overlapping sub-band full duplex) is:

[0048] Network-side full-duplex: From the network's perspective, uplink and downlink transmissions can occur simultaneously within different frequency sub-bands. To prevent interference between uplink and downlink transmissions, a guard band is reserved between the frequency sub-bands corresponding to different transmission directions (e.g., uplink and downlink sub-bands).

[0049] Terminal-side half-duplex or full-duplex: When the terminal supports half-duplex, only uplink or downlink transmissions can be performed at the same time, not both. Understandably, in this case, the network's uplink and downlink transmissions at the same time can only be directed to different terminals. When the terminal supports full-duplex, similar to the network, uplink and downlink transmissions can be performed simultaneously within different frequency subbands at the same time.

[0050] (2)TDD pattern;

[0051] When NR cells are deployed on asymmetric spectrum, TDD duplexing is generally used. In this case, the TDD uplink and downlink common configuration (TDD-UL-DL-Config Common or TDD-UL-DL-Configuration Common) can be configured in the cell common parameters to indicate TDD frame structure information, including the TDD frame period, the number of complete downlink / uplink time slots (Slots) contained in a single frame period, and the number of additional downlink / uplink symbols (Symbols) contained in addition to the complete downlink / uplink slots. Optionally, radio resource control (RRC) signaling can also be used to independently configure a TDD uplink and downlink dedicated configuration (TDD-UL-DL-ConfigDedicated or tdd-UL-DL-ConfigurationDedicated) for each UE, which is used to further modify the uplink and downlink Symbol configuration of one or more Slots in a single frame period based on TDD-UL-DL-ConfigCommon (that is, the initial value of the uplink and downlink Symbol configuration of the Slot is specified by TDD-UL-DL-ConfigCommon, and then further modified by TDD-UL-DL-ConfigDedicated. This modification is only applied to the UE that receives this RRC signaling), but the modification here is limited to further indicating the flexible symbol (Flexible symbol) in the Slot (that is, the transmission direction is not clear, and whether it is used for downlink transmission or uplink transmission can be determined later as needed) as a DL / UL symbol, and the DL / UL symbol in the Slot cannot be modified to other directions.

[0052] The above-mentioned TDD-UL-DL-ConfigCommon and / or TDD-UL-DL-ConfigDedicated are optional configurations. Since these configuration information can only be semi-statically configured / modified based on the information of the RRC layer, each Symbol within a single TDD frame period determined by these configuration information (combined with the transmission direction configured for it) can also be referred to as a semi-static uplink / downlink / flexible symbol (Semi-static DL / UL / flexible symbol).

[0053] When the above-mentioned TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are not configured, there is no clear concept of TDD frame period. At this time, each Slot / Symbol in each radio frame of the NR cell can be understood as a semi-static flexible symbol or time slot (Semi-static flexible slot / symbol).

[0054] To facilitate the description of the solution below, the following concepts and explanations are first given.

[0055] (1) TDD pattern configuration information;

[0056] Based on the TDD pattern configuration information provided by the network to the UE, for example, the TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated provided for a component carrier (CC) / serving cell of the UE, the following symbol types can be distinguished:

[0057] Downlink (DL) symbol (DL symbol);

[0058] Uplink (UL) symbol (UL symbol);

[0059] Flexible symbol.

[0060] When tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated is not provided for a CC / Serving cell, each Symbol may be considered as a Flexible symbol, or the rules corresponding to the Flexible symbol may be followed.

[0061] (2) SBFD configuration information;

[0062] The SBFD configuration information is used to determine the time-frequency location where SBFD operations can be performed (for example, full-duplex on the network side, half-duplex or full-duplex on the UE side). It can also be understood as determining the time domain location and frequency domain location of the uplink subband (UL subband), downlink subband (DL subband), guard bandwidth (Guardband), etc. used for SBFD operation.

[0063] For the convenience of description, the concept of SBFD time domain unit can be introduced (the time domain unit can be a time slot (Slot), sub-time slot (Sub-slot), Symbol, etc.), which is used to determine the time domain granularity and / or position of the SBFD operation (SBFD operation); within the SBFD time domain unit, the UL subband, DL subband, Guardband, etc. can be further configured / distinguished in the frequency domain dimension.

[0064] Accordingly, the SBFD configuration information includes at least one of the following first and second items:

[0065] The first item: time domain configuration information of the SBFD time domain unit;

[0066] The time domain configuration information of the SBFD time domain unit is used to determine the time domain position of the SBFD time domain unit and can indicate either of the following SBFD time domain configuration mode 1 and SBFD time domain configuration mode 2:

[0067] SBFD time domain configuration mode 1: In at least one period determined based on the TDD pattern configuration information, predetermined time domain units within at least one time window are SBFD time domain units.

[0068] The period here can be understood as a period determined based on pattern 1 (pattern 1) (optionally, further including pattern 2) and reference subcarrier spacing (referenceSubcarrierSpacing) in tdd-UL-DL-ConfigurationCommon, assuming its length is TDD_Period. Within the duration corresponding to each N (N ≥ 1) TDD_Period (corresponding to the time domain period of the SBFD configuration), M (M ≥ 1) time windows can be determined.

[0069] SBFD time domain configuration mode 2: Based on independently configured periods and offsets, predetermined time domain units within a periodically occurring time window are defined as SBFD time domain units.

[0070] Here, the "independently configured period" (corresponding to the time domain period configured by SBFD) is decoupled from the period determined based on the TDD pattern configuration information, or the TDD pattern and SBFD time domain configuration information are configured independently or separately by the base station, and the two may be aligned or not aligned. The "offset" here is used to determine the start / end time of each period obtained based on the "independently configured period". For example, assuming that the configured period and offset are Periodicity and Offset respectively, and the unit is Slot. When the system frame number (SFN) n f and Slot Number satisfy When, it can be understood as from Slot The start / end moment of The number of slots included in each system frame. At least one time window can be further determined in each cycle, and the predetermined time domain unit in each time window is the SBFD time domain unit.

[0071] The starting point and length, or the starting point and ending point, of each time window involved in SBFD time domain configuration mode 1 and SBFD time domain configuration mode 2 can be specified by the protocol or configured by higher-layer signaling. For example, each SBFD time domain period can be directly assumed to correspond to a single time window (i.e., the start / end time of this time window is exactly the same as the start / end time of this period). Alternatively, at least one time window can be further configured within each SBFD time domain period, with the time range corresponding to each time window falling within the time range corresponding to this period. The starting point or ending point of the time window can be a time offset relative to the start time of this period. The period and offset in SBFD time domain configuration mode 2 can be specified by the protocol or configured by higher-layer signaling.

[0072] When configuring / specifying the time offset corresponding to the start / end point of the above-mentioned time window, the length of the time window, and the period and offset of the SBFD configuration in SBFD time domain configuration method 2, the time domain granularity indication of the system time domain unit (Slot, Sub-slot, Symbol, etc.) can be used, or the time domain granularity indication of the absolute time unit (ms, etc.) can be used.

[0073] The aforementioned “predetermined time domain unit within the time window” may be any one of the following items A1 to A3:

[0074] A1: all time domain units within this time window;

[0075] A2: All time domain units within this time window that meet predefined conditions;

[0076] A time domain unit is considered to meet the predefined condition when it satisfies at least one of the following (a) to (d):

[0077] (a) The domain unit is determined to be DL or Flexible based on the TDD pattern configuration information. For example, when the domain unit is a symbol, the symbol is configured as a DL symbol or a Flexible symbol based on the TDD pattern configuration information.

[0078] (b) This domain unit is not determined as UL or Flexible based on the TDD pattern configuration information;

[0079] (c) The domain unit is not a synchronization signal block (SSB) symbol. The SSB here can be a cell-defined SSB (CD-SSB) and / or a non-cell-defined SSB (NCD-SSB).

[0080] (d) The domain unit does not overlap with the control resource set (CORESET) #0 (CORESET#0) or is not occupied by CORESET#0. For example, when the domain unit is a symbol, the symbol does not belong to the symbol occupied by CORESET#0.

[0081] A3: further indicated time domain units within this time window;

[0082] For example, a bitmap or list is used to indicate that all or some of the time domain units within the time window are SBFD time domain units. When a bitmap is used, each valid indication bit in the bitmap can correspond to a single time domain unit (e.g., a slot or symbol) within the time window. When a valid indication bit takes a predefined value (e.g., 1), it indicates that the corresponding time domain unit is an SBFD time domain unit.

[0083] For example, when SBFD time domain configuration mode 1 is adopted and the TDD pattern is DDDSU, a single time window (M=1; the time offset of the starting point of the time window relative to the start time of the TDD_Period is 14 symbols, and the length of the time window is 38 symbols) starting from the second DL slot of this TDD pattern can be configured within each TDD_Period (N=1). This time window covers all DL symbols in the first part of the second DL slot, the third DL slot, and the special slot (for example, its slot format is 10D:2F:2U, that is, the time slot ratio of the downlink time slot, flexible time slot, and uplink time slot is 10:2:2), and all symbols within this time window are SBFD symbols.

[0084] The second item: Subband configuration information in the SBFD time domain unit;

[0085] The subband configuration information in the SBFD time domain unit is used to determine the frequency domain position and width of the UL subband, DL subband, Guardband, etc. in the SBFD time domain unit.

[0086] Generally, it can be assumed that the subband configuration information applied / effective in each SBFD time domain unit is the same; optionally, the subband configuration information applied / effective in different SBFD time domain units may be different. In this case, multiple sets of applied / effective subband configuration information may exist simultaneously in the cell / carrier where the SBFD operation can be performed, and each set of subband configuration information may correspond to at least one SBFD time domain unit.

[0087] Each set of subband configuration information may indicate at least one of the following items B1 to B4:

[0088] B1: frequency domain start / end position and / or frequency domain width of at least one UL subband;

[0089] B2: frequency domain start / end position and / or frequency domain width of at least one DL subband;

[0090] B3: Frequency domain start / end position and / or frequency domain width of at least one flexible subband;

[0091] B4: Frequency domain start / end position and / or frequency domain width of at least one guardband.

[0092] When indicating the above-mentioned frequency domain start / end position, the predefined reference point corresponding to the frequency domain position, or the frequency domain offset relative to the predefined reference point may be indicated.

[0093] The predefined reference point may be any one of the following C1 to C5:

[0094] C1: Point A of the cell (or the center frequency of Subcarrier0 of Common Resource Block 0 (CRB 0)) can be determined based on the frequency domain position and offset indication of the CD-SSB of this cell (for example, parameter SIB1->offsetToPointA; "->" is used here to represent a field in the previous message or field, for example, parameter SIB1->offsetToPointA represents the offsetToPointA parameter in the SIB1 message, and similar expressions below follow the explanation here), or, based on the Absolute Radio Frequency Channel Number (ARFCN) configured on the network side (for example, parameter ServingCellConfigCommon->absoluteFrequencyPointA).

[0095] C2: Physical Resource Blocks (PRBs) at predefined locations within a DL / UL Bandwidth Part (BWP), or PRBs at predefined locations within a DL / UL BWP in a cell supporting SBFD operation, such as PRB 0.

[0096] C3: The starting / ending frequency of the cell's CD-SSB or CORESET#0, or the first / last CRB overlapping with the cell's CD-SSB or CORESET#0 (the corresponding SCS can be specified by the protocol or configured by higher-layer signaling, for example, by the parameter MIB->subCarrierSpacingCommon).

[0097] C4: The frequency corresponding to the indicated absolute frequency point number ARFCN.

[0098] C5: Starting CRB of the initial BWP (Initial BWP).

[0099] When indicating the frequency domain width and the frequency domain offset, any one of the following D1 and D2 may be indicated:

[0100] D1: Indicates the corresponding absolute frequency domain width, such as an integer or floating-point value based on predefined units ([M]Hz, etc.).

[0101] D2: Indicates the number of resource blocks (RBs) based on the reference SCS. The reference SCS may be specified by the protocol or configured by higher-layer signaling and may include at least one of the following (a) to (f):

[0102] (a) SCS explicitly specified by the protocol, such as unified or differentiated frequency range (FR) or band;

[0103] (b) SCS of a specified SSB (CD-SSB corresponding to the cell, or a certain NCD-SSB, etc.);

[0104] (c) SCS (Subcarrier spacing for SIB1, Msg.2 / 4 for initial access, paging and broadcast SI-messages.) indicated by the parameter MIB->subCarrierSpacingCommon;

[0105] (d) The SCS corresponding to the Initial BWP, or the SCS corresponding to the DL / UL BWP supporting SBFD operation;

[0106] (e) the reference SCS corresponding to the TDD pattern configuration information of the cell (e.g., indicated by the parameter tdd-UL-DL-ConfigurationCommon->referenceSubcarrierSpacing);

[0107] (f) SCS explicitly configured by the newly introduced parameters.

[0108] Generally, each set of subband configuration information involves the same reference SCS for the configuration of UL / DL / Flexible subband and Guardband. Optionally, for a certain set of subband configuration information, the reference SCS for the configuration of different subbands or guardbands may be different.

[0109] Optionally, for at least one of the SBFD time domain units determined by the SBFD configuration information, its applicable duplex mode may be further differentiated. For example, consider the following two duplex modes (the subband configuration information in the SBFD time domain units applicable to different duplex modes is required to be the same or uniformly configured, or may be different or configured separately):

[0110] Duplex mode 1: For Duplex mode 1, the network side supports full-duplex SBFD operation; the UE side supports only half-duplex SBFD operation. That is, within a single SBFD symbol, the UE can only perform uplink transmission or downlink reception, and cannot perform uplink transmission and downlink reception based on FDM simultaneously.

[0111] Duplex Mode 2: The network side supports full-duplex SBFD operation; the UE side supports full-duplex SBFD operation, that is, the UE can simultaneously perform FDM-based uplink transmission and downlink reception within a single SBFD symbol.

[0112] For example, for Rel-19SBFD capable / aware UE (SBFD capable UE, i.e., UE with SBFD capability; SBFD aware UE, i.e., UE that is aware of the SBFD deployment on the network side (including whether SBFD is deployed, and the SBFD information configured or applied when deployed, etc.)), it may be specified by the protocol or configured by high-layer signaling to only support Duplex mode 1; for Advanced UE, it may be specified by the protocol or configured by high-layer signaling to only support Duplex mode 2, or to support both Duplex mode 1 and Duplex mode 2.

[0113] It can be understood that when a certain time domain unit of a cell is not configured / determined as an SBFD time domain unit, it can be called a non-SBFD time domain unit.

[0114] The information processing method provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0115] As shown in FIG2 , an embodiment of the present application provides an information processing method, including:

[0116] Step 201: The terminal obtains first sub-band full-duplex SBFD configuration information, where the first SBFD configuration information includes at least one of general SBFD configuration information and terminal-specific SBFD configuration information.

[0117] Among them, the general SBFD configuration information is the SBFD information uniformly configured for all terminals of the first object service and / or the SBFD information applied to all terminals of the first object service, and the terminal-specific SBFD configuration information is the SBFD information independently configured for the terminal of the first object service and / or the SBFD information applied to the terminal of the first object service.

[0118] Optionally, the first object includes at least one of a component carrier (CC), a serving cell (Serving cell), and a bandwidth part (BWP). Optionally, the general SBFD configuration information or the terminal-specific SBFD configuration information includes at least one of the following:

[0119] Time domain configuration information of the SBFD time domain unit, where the time domain configuration information is used to determine the time domain position of the SBFD time domain unit. The time domain configuration information of the SBFD time domain unit has been described above and will not be repeated here;

[0120] The subband configuration information in the SBFD time domain unit is used to determine the frequency domain position and / or width of the subband in the SBFD time domain unit. The subband configuration information in the SBFD time domain unit has been described above and will not be repeated here.

[0121] Optionally, the SBFD time domain unit is a predetermined time domain unit within a first time window, or the SBFD time domain unit is a predetermined time domain unit within a second time window;

[0122] The first time window is at least one time window within at least one period determined based on TDD mode configuration information, and the second time window is a periodically occurring time window determined based on an independently configured period and offset.

[0123] Optionally, the predetermined time domain unit within the target time window includes any one of the following (a) to (c):

[0124] (a) All time domain units within the target time window;

[0125] (b) Time domain units that meet predefined conditions within the target time window; the predefined conditions have been explained in the above description and will not be repeated here.

[0126] (c) the time domain unit indicated by the network-side device within the target time window;

[0127] The target time window includes the first time window or the second time window.

[0128] Optionally, the terminal obtains the first SBFD configuration information sent by the network side device through a system information block (SIB) or UE-specific radio resource control (RRC) signaling. Exemplarily, the SIB may be SIB1, and the RRC signaling may be an RRC reconfiguration message or an RRC release message.

[0129] The above-mentioned common SBFD configuration information (Common SBFD configuration information) or public SBFD configuration information can be understood as the consistent / same SBFD configuration information applied to all UEs served by this CC / Serving cell or a certain BWP of this CC / Serving cell.

[0130] When the configuration level of the Common SBFD configuration information is CC / Serving cell common (that is, SBFD configuration information uniformly applied to this CC / Serving cell configuration), the Common SBFD configuration information can be notified in the System Information Block (SIB) or UE-specific Radio Resource Control (RRC) signaling (CC / Serving cell level configuration information element (IE)), for example, a corresponding sub-IE is introduced in the IE corresponding to at least one of the following (a) to (c) to indicate the Common SBFD configuration information (here "->" is used to indicate an IE or parameter in the previous message or IE, and multiple "->" structures can be cascaded to indicate the configuration path of the last listed IE or parameter layer by layer; the name listed in the brackets () is the IE type to which the IE or parameter is applicable, for example, servingCellConfigCommon (ServingCellConfigCommonSIB) indicates that the type of IE servingCellConfigCommon is ServingCellConfigCommonSIB, that is, IE The settings of the sub-IEs / sub-parameters (or further included IEs / parameters) of servingCellConfigCommon refer to the corresponding provisions of the IE type ServingCellConfigCommonSIB. The relationship between the IE type and the IE name is similar to the relationship between the class / structure type and the object in the C language. The following configuration paths are explained here:

[0131] (a) SIB1->servingCellConfigCommon (ServingCellConfigCommonSIB), indicating the Common SBFD configuration information in the serving cell common configuration of SIB1;

[0132] (b) RRCReconfiguration->reconfigurationWithSync(ReconfigurationWithSync)->spCellConfigCommon(ServingCellConfigCommon), i.e., for the special cell (SpCell), the Common SBFD configuration information is indicated in the synchronization reconfiguration parameter of the RRC reconfiguration message;

[0133] (c) RRCReconfiguration->SCellConfig->sCellConfigCommon (ServingCellConfigCommon), that is, for the secondary cell (SCell), the Common SBFD configuration information is indicated in the SCell common configuration parameter in the SCell configuration of the RRC reconfiguration message.

[0134] When the configuration level of the Common SBFD configuration information is BWP common (i.e., SBFD configuration information uniformly applied to a certain BWP configuration of this CC / Serving cell), the Common SBFD configuration information may be notified in the SIB or UE-specific RRC signaling (BWP level configuration IE), for example, by introducing a corresponding sub-IE into the IE corresponding to at least one of the following (a) to (f) to indicate the Common SBFD configuration information:

[0135] (a) ServingCellConfig->BWP-Downlink->bwp-Common (BWP-DownlinkCommon), that is, for the downlink BWP of this CC / Serving cell (downlink BWP other than the initial downlink BWP), the Common SBFD configuration information is indicated in the common BWP parameter of the downlink BWP parameter in the serving cell configuration parameter of the RRC reconfiguration message;

[0136] (b) ServingCellConfigCommon->downlinkConfigCommon(DownlinkConfigCommon)->initialDownlinkBWP(BWP-DownlinkCommon), i.e., the initial downlink BWP for this CC / Serving cell, indicating the Common SBFD configuration information in the downlink common configuration parameters of the serving cell common configuration in the RRC reconfiguration message;

[0137] (c) ServingCellConfigCommonSIB->downlinkConfigCommon(DownlinkConfigCommonSIB)->initialDownlinkBWP(BWP-DownlinkCommon), i.e., the downlink common configuration parameter indication Common SBFD configuration information in the serving cell common configuration SIB;

[0138] (d) ServingCellConfig->BWP-Uplink->bwp-Common (BWP-UplinkCommon), i.e., for the uplink BWP of this CC / Serving cell (except the initial uplink BWP), indicate the Common SBFD configuration information in the BWP common configuration parameter of the uplink BWP information configured by the serving cell in the RRC reconfiguration message;

[0139] (e) ServingCellConfigCommon->uplinkConfigCommon / supplementaryUplinkConfig(UplinkConfigCommon)->initialUplinkBWP(BWP-UplinkCommon), i.e., for the initial uplink BWP of this CC / Serving cell, the Common SBFD configuration information is indicated in the initial uplink BWP parameter in the uplink common configuration (or uplink supplementary configuration) of the serving cell common configuration in the RRC reconfiguration message;

[0140] (f) ServingCellConfigCommonSIB->uplinkConfigCommon / supplementaryUplink (UplinkConfigCommonSIB)->initialUplinkBWP (BWP-UplinkCommon), i.e., notifying the Common SBFD configuration information in the initial uplink BWP parameter in the uplink common configuration (or uplink supplementary configuration) of the serving cell common configuration SIB.

[0141] The terminal-specific SBFD configuration information (hereinafter referred to as dedicated SBFD configuration information) can be understood as independent configuration of the SBFD configuration information for each UE served by the CC / Serving cell, or a BWP of the CC / Serving cell. The network can configure the same or different SBFD configuration information for different UEs based on implementation to better match the actual situation of each UE and provide greater flexibility.

[0142] Potential motivations for introducing dedicated SBFD configuration information may include at least one of the following:

[0143] The first item is to configure different SBFD time domain unit numbers or densities for different UEs;

[0144] When different UEs are located in different locations (center / edge, etc.) of the cell coverage area, or have different uplink power levels or different channel qualities, the coverage enhancement requirements (such as whether to enable repetition transmission or the number of repetitions required when repetition transmission is enabled) may vary, and thus the required number of (continuous) SBFD time domain units may be different.

[0145] Different UEs have different uplink and downlink traffic ratios, or different requirements for the amount of data to be transmitted, buffering time, and Quality of Service (QoS). The ratio of available uplink and downlink resources can be adjusted by adjusting the number or density of SBFD time-domain units.

[0146] Second item: configure different UL subband frequency domain positions and / or frequency domain widths for different UEs;

[0147] Different UEs may support different uplink bandwidths and / or require different amounts of uplink resources. In this case, different UL subband frequency domain widths may be configured for different UEs based on UE capabilities, service data characteristics, etc. Accordingly, when different UL subband frequency domain widths are configured for different UEs, the frequency domain positions (including starting / ending positions, etc.) of the UL subbands may also be different.

[0148] For example, the network plans to configure the middle 30 MHz of a 100 MHz TDD carrier for a UL subband. For a UE that only supports 20 MHz radio (see UE2 in Figure 3), the network also wants to enable SBFD to improve performance. Assume that the UE configures a UL subband for a BWP of the CC / Serving cell corresponding to the TDD carrier. The 20 MHz corresponding to this BWP covers the upper 8 MHz of the lower DL subband, the lower 7 MHz of the middle UL subband, and the 5 MHz of the Guardband.

[0149] Furthermore, suppose two UEs each support only 20 MHz radio. To fully utilize the frequency resources within this TDD carrier, the network can stagger the frequency domains covered by the BWPs configured for these two UEs. For one UE, the UL subband is configured according to the pattern corresponding to UE2 in Figure 3, while the UL subband configured for the other UE covers the upper 7 MHz portion of the middle UL subband. There is no frequency overlap between the UL subbands configured for the two UEs.

[0150] Item 3: Configure different Guardband frequency domain positions and / or frequency domain widths for different UEs;

[0151] Different UEs may have different implementations and capabilities, resulting in different Guardband frequency domain widths required to mitigate inter-UE inter-subband cross link interference (CLI). Accordingly, when different Guardband frequency domain widths are configured for different UEs, the Guardband frequency domain locations (including start and end locations, etc.) may also vary.

[0152] Item 4: Configure different Duplex modes for different UEs;

[0153] The specific implementation and capabilities of different UEs may be different, and thus the Duplex modes supported within the SBFD time domain unit may also be different.

[0154] When the configuration level of the dedicated SBFD configuration information is CC / Serving cell dedicated (i.e., SBFD configuration information applied to a certain UE configured for this CC / Serving cell; SBFD configuration information configured for different UEs for this CC / Serving cell can be independently configured and can be the same or different), the dedicated SBFD configuration information can be notified in the UE-specific RRC signaling (CC / Serving cell level configuration IE), for example, a corresponding sub-IE is introduced in the IE corresponding to at least one of the following (a) and (b) to indicate the dedicated SBFD configuration information:

[0155] (a) RRCReconfiguration->SpCellConfig->spCellConfigDedicated(ServingCellConfig), i.e., for SpCell, the Dedicated SBFD configuration information is indicated in the SpCell dedicated configuration in the SpCellConfig of the RRC reconfiguration message;

[0156] (b) RRCReconfiguration->SCellConfig->sCellConfigDedicated (ServingCellConfig), that is, for the SCell, the Dedicated SBFD configuration information is indicated in the SCell dedicated configuration parameter of SCellConfig in the RRC reconfiguration message.

[0157] When the configuration level of the dedicated SBFD configuration information is BWP dedicated (that is, the SBFD configuration information applied to a certain BWP configuration of a certain UE for this CC / Serving cell; therefore, the SBFD configuration information of the UE for different BWP configurations of this CC / Serving cell can be independently configured and can be the same or different), the dedicated SBFD configuration information can be notified in the UE-specific RRC signaling (BWP level configuration IE), for example, a corresponding sub-IE is introduced in the IE corresponding to at least one of the following (a) to (d) to indicate the dedicated SBFD configuration information:

[0158] (a) ServingCellConfig->BWP-Downlink->bwp-Dedicated (BWP-DownlinkDedicated), that is, for the downlink BWP of this CC / Serving cell (downlink BWP other than the initial downlink BWP), the dedicated SBFD configuration information is indicated in the dedicated BWP configuration of the downlink BWP configured by the serving cell in the RRC reconfiguration message;

[0159] (b) ServingCellConfig->initialDownlinkBWP (BWP-DownlinkDedicated), i.e., the initial downlink BWP for this CC / Serving cell, indicating the Dedicated SBFD configuration information in the initial downlink BWP parameter of the serving cell configuration in the RRC reconfiguration message;

[0160] (c) ServingCellConfig->BWP-Uplink->bwp-Dedicated (BWP-UplinkDedicated), that is, for the uplink BWP of this CC / Serving cell (uplink BWP other than the initial uplink BWP), the dedicated BWP parameter in the uplink BWP configured by the serving cell in the RRC reconfiguration message indicates the Dedicated SBFD configuration information;

[0161] (d) ServingCellConfig->uplinkConfig / supplementaryUplink(UplinkConfig)->initialUplinkBWP(BWP-UplinkDedicated), that is, for the initial uplink BWP of this CC / Serving cell, the Dedicated SBFD configuration information is indicated in the initial uplink BWP parameter of the uplink configuration (or uplink supplementary configuration) of the RRC reconfiguration message.

[0162] In an embodiment of the present application, the terminal obtains first SBFD configuration information, and the first SBFD configuration information includes at least one of general SBFD configuration information and terminal-specific SBFD configuration information. Through the above-mentioned general SBFD configuration information, the SBFD information uniformly configured for all terminals of the first object service and / or the SBFD information applied by all terminals of the first object service can be obtained. Through the above-mentioned terminal-specific SBFD configuration information, the SBFD information independently configured for the terminal of the first object service and / or the SBFD information applied by the terminal of the first object service can be obtained. Thus, through the first SBFD configuration information, the terminal of the first object service can obtain the corresponding SBFD configuration information, so that the terminal of the first object service can perform the SBFD operation corresponding to the SBFD configuration information, thereby effectively ensuring the deployment of SBFD operations in the TDD network, and then effectively improving the uplink capacity, latency, coverage and other performance.

[0163] Optionally, the terminal acquires first sub-band full-duplex SBFD configuration information, including:

[0164] Obtaining a radio resource control (RRC) release message; wherein the RRC release message indicates at least one set of SBFD configuration information, each set of SBFD configuration information being applicable to all objects that meet an applicable condition corresponding to the SBFD configuration information; or, the RRC release message indicates at least one object and a set of SBFD configuration information applicable to each of the objects;

[0165] If the first object meets the target applicability condition, the target SBFD configuration information is determined as the first SBFD configuration information, or if the first object is the target object, a set of SBFD configuration information applicable to the target object is determined as the first SBFD configuration information, wherein the target SBFD configuration information is a set of SBFD configuration information among the at least one set of SBFD configuration information, the target applicability condition corresponds to the target SBFD configuration information, and the target object is an object indicated in the RRC release message.

[0166] In the embodiment of the present application, the RRC release message is used to transfer the UE from the RRC connected mode (RRC_CONNECTED mode) to the RRC idle state or inactive mode (RRC_IDLE / INACTIVE mode).

[0167] Optionally, the applicable conditions include at least one of the following (a) to (f):

[0168] (a) Belongs to a designated public land mobile network (PLMN); the designated PLMN here can be the PLMN to which the primary serving cell (under dual connectivity) (Primary cell, PCell) of the primary serving cell / primary cell group in which the UE is located before receiving the RRCRelease message belongs, or the PLMN explicitly indicated in the RRCRelease message (for example, indicated by PLMN-Identity).

[0169] (b) Located in a designated frequency layer; the designated frequency layer here may be the frequency layer corresponding to the PCell in which the UE is located before receiving the RRCRelease message, or the frequency layer explicitly indicated in the RRCRelease message; different frequency layers may be distinguished by the center frequency of the CD-SSB and the corresponding SCS. For example, when the center frequency of the CD-SSB of two cells is the same and the corresponding SCS is also the same, the two cells are considered to correspond to the same frequency layer;

[0170] (c) located within a designated area; the designated area here may be the Tracking Area (TA) or Radio Access Network (RAN) area to which the PCell to which the UE belongs before receiving the RRCRelease message, or the RAN-based notification area indicated in the RRCRelease message (when the RRCRelease message is used to transition the UE from RRC_CONNECTED mode to RRC_INACTIVE mode), or the Tracking area / RAN area explicitly indicated in the RRCRelease message;

[0171] (d) Not in the Reserved or Barred status;

[0172] (f) Indicated in the RRC release message, for example, in the cell list indicated in the RRC release message.

[0173] Optionally, Common SBFD configuration information corresponding to at least one cell (or applied to at least one cell) is provided to the UE in the RRCRelease message, and / or Dedicated SBFD configuration information corresponding to at least one cell (or applied to at least one cell) is provided to the UE in the RRCRelease message.

[0174] Exemplarily, providing the Common SBFD configuration information corresponding to at least one cell to the UE in the RRCRelease message may include at least one implementation manner from the following implementation manners 1 to 3:

[0175] Implementation method 1: Indicate a single set of Common SBFD configuration information in the RRCRelease message, which can be applied to any cell that meets predefined conditions (i.e., applicability conditions);

[0176] Implementation method 2: Indicate at least one set of Common SBFD configuration information in the RRCRelease message, where each set of Common SBFD configuration information can be applied to any cell that meets the corresponding applicable conditions.

[0177] It can be understood that the applicable conditions corresponding to different Common SBFD configuration information in this implementation are mutually orthogonal (that is, when a cell meets the applicable conditions corresponding to one set of Common SBFD configuration information, it must not meet the applicable conditions corresponding to another set of Common SBFD configuration information) to avoid the UE from matching a single cell with multiple sets of Common SBFD configuration information.

[0178] Implementation method three: In the RRCRelease message, the corresponding Common SBFD configuration information is indicated for each listed cell.

[0179] Here, the Common SBFD configuration information indicated for each listed cell may be the same or different.

[0180] It can be understood that the configuration level of the Common SBFD configuration information provided in the RRCRelease message can be either CC / Serving cell common or BWP common (for example, Initial DL / UL BWP applied to the corresponding cell).

[0181] When the Common SBFD configuration information is notified in a cell broadcast (eg, SIB1), it is unnecessary to further notify the Common SBFD configuration information in an RRCRelease message, because the UE must read the necessary system broadcast information of a cell before accessing the cell.

[0182] When the Common SBFD configuration information is not notified in the cell broadcast, for this cell, only the UE that has been notified of its corresponding Common SBFD configuration information in the RRCRelease message can use the uplink resources determined based on the Common SBFD configuration information in the initial access (for example, for Physical Random Access Channel (PRACH) transmission, Physical Uplink Shared Channel (PUSCH) transmission corresponding to Msg3 / MsgA, Physical Uplink Control Channel (PUCCH) transmission corresponding to Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) of Msg4 / MsgB, etc.), so that the network side can effectively control the UE range using UL subband resources during the initial access process.

[0183] Optionally, a validity period may be further specified in the protocol or in the RRCRelease message for the indicated or notified Common SBFD configuration information. Upon receipt of the Common SBFD configuration information notified in the RRCRelease message, the UE considers the Common SBFD configuration information valid only during this validity period. After this validity period has expired, the UE determines that the Common SBFD configuration information is no longer valid and may discard it.

[0184] In addition, the method of providing the Dedicated SBFD configuration information corresponding to at least one cell (or applied to at least one cell) to the UE in the RRCRelease message may refer to the above-mentioned method of providing the Common SBFD configuration information to the UE in the RRCRelease message.

[0185] Optionally, the method of the embodiment of the present application further includes:

[0186] In a contention-based random access process, based on a first correspondence between terminal-specific SBFD configuration information and a random access opportunity (RACH Occasion, RO), determining a first RO corresponding to the terminal-specific SBFD configuration information in the first SBFD configuration information;

[0187] Perform uplink transmission according to the first RO.

[0188] In the first correspondence, the terminal-specific SBFD configuration information and the RO may correspond one-to-one, or at least one RO may correspond to multiple sets of different terminal-specific SBFD configuration information.

[0189] The uplink resources determined based on the above terminal-specific SBFD configuration information can be used for PRACH transmission, PUSCH transmission corresponding to Msg3 / MsgA, PUCCH transmission corresponding to HARQ-ACK of Msg4 / MsgB, etc.

[0190] Optionally, the performing uplink transmission according to the first RO includes:

[0191] According to the second correspondence between the terminal-specific SBFD configuration information and the preamble code set, a first preamble code is sent in the first RO, where the first preamble code is a preamble code in the first preamble code set, and the first preamble code set is a preamble code set corresponding to the terminal-specific SBFD configuration information in the first SBFD configuration information.

[0192] In an embodiment of the present application, when the UE uses uplink resources determined based on the dedicated SBFD configuration information in a contention-based random access process (including a scenario of initial access to a cell) (for example, for PRACH transmission, PUSCH transmission corresponding to Msg3 / MsgA, PUCCH transmission corresponding to HARQ-ACK of Msg4 / MsgB, etc.), the network side may distinguish different dedicated SBFD configuration information corresponding to each UE based on any one of the following SBFD configuration information identification mode 1 and SBFD configuration information identification mode 2:

[0193] SBFD configuration information identification method 1: for independent RO (Separate RO);

[0194] The network side independently configures the RO for the uplink resources in each set of Dedicated SBFD configuration information (assuming that the ROs corresponding to the different sets of Dedicated SBFD configuration information do not overlap with each other; for example, when a block of time-frequency resources is mapped to the RO corresponding to a certain set of Dedicated SBFD configuration information, this block of time-frequency resources is not allowed to be mapped to the RO corresponding to another set of Dedicated SBFD configuration information). Based on the correspondence between the RO and the Dedicated SBFD configuration information, the Dedicated SBFD configuration information corresponding to the UE sending the preamble in a certain RO can be determined. Generally, to simplify configuration, each set of Dedicated SBFD configuration information can correspond to an independent SSB to RO mapping.

[0195] SBFD configuration information identification method 2: for shared RO (Shared RO);

[0196] Among the ROs that can be used by UEs applying different dedicated SBFD configuration information, at least one RO overlaps (for example, at least one RO corresponds to multiple different sets of dedicated SBFD configuration information).

[0197] One possible implementation is: assuming that the Common SBFD configuration information is notified in a cell broadcast (e.g., SIB1), and the UE can determine the initial RO and the initial SSB to RO mapping based on this Common SBFD configuration information (at this time, the initial SSB to RO mapping determined by all SBFD-aware UEs or SBFD-capable UEs are completely consistent). The UE further determines its actually available RO based on predefined rules. For example, based on the interaction between the Common SBFD configuration information and the Dedicated SBFD configuration information (for a detailed description, see below), when a certain RO does not completely fall within the time domain unit to which a valid RO can be mapped (including the uplink time domain unit and the determined SBFD time domain unit, etc.), the UE determines that the RO is actually unavailable; when a certain RO completely falls within the time domain unit to which a valid RO can be mapped and overlaps with the determined SBFD time domain unit, the UE determines that it is actually available only when it is completely located within the UL subband determined to be applied within this determined SBFD time domain unit. For another example, the UE determines whether a certain initial RO is actually available based on the RO Mask (combined with / indicated simultaneously with the Dedicated SBFD configuration information) (further, the UE expects that this RO falls completely within the time domain unit to which the valid RO can be mapped, and when there is an overlap with the determined SBFD time domain unit, it is completely located within the UL subband determined for application within the overlapping SBFD time domain unit).

[0198] In order to further distinguish UEs that use resources within the same RO but correspond to different dedicated SBFD configuration information, corresponding preamble subsets can be indicated for different dedicated SBFD configuration information (that is, in the same RO, mutually orthogonal preamble subsets are used); based on the correspondence between the preamble and the dedicated SBFD configuration information, the network side can determine the dedicated SBFD configuration information corresponding to the UE sending the preamble in this RO.

[0199] After the network side detects the Preamble sent by a UE and identifies its corresponding Dedicated SBFD configuration information, it can indicate appropriate time-frequency resources for the subsequent uplink transmission of the random access process based on this Dedicated SBFD configuration information. For example, the network side indicates the time-frequency resources corresponding to the PUSCH transmission corresponding to Msg3 / MsgA and the PUCCH transmission corresponding to the HARQ-ACK of Msg4 / MsgB in the UL subband within the SBFD time domain unit determined based on this Dedicated SBFD configuration information.

[0200] Optionally, when the first SBFD configuration information includes general SBFD configuration information and terminal-specific SBFD configuration information, the terminal performs a first operation, where the first operation includes one of the following operations 1 and 2:

[0201] Operation 1: Determine that the terminal-specific SBFD configuration information is valid SBFD configuration information;

[0202] Operation 2: Determine that second SBFD configuration information is effective SBFD configuration information, where the second SBFD configuration information is jointly determined based on the general SBFD configuration information and the terminal-specific SBFD configuration information.

[0203] Generally, a cell may use only Common SBFD configuration information or Dedicated SBFD configuration information. Optionally, a cell may use both Common SBFD configuration information and Dedicated SBFD configuration information.

[0204] For the above operation 1: Dedicated SBFD configuration information can completely rewrite / override Common SBFD configuration information;

[0205] In operation 1, both the Common SBFD configuration information and the Dedicated SBFD configuration information are complete configuration information, for example, including the time domain configuration information of the SBFD time domain unit and the subband configuration information within the SBFD time domain unit, so as to completely determine the time-frequency positions of the UL subband, DL subband, Guardband, etc.

[0206] When only Common SBFD configuration information is provided for a UE, the UE uses the Common SBFD configuration information. When Dedicated SBFD configuration information (which is identical to the Common SBFD configuration information or differs in at least one item) is further provided for the UE, the UE uses only the Dedicated SBFD configuration information. Alternatively, if there is a conflict between the Dedicated SBFD configuration information and the Common SBFD configuration information, the UE uses only the Dedicated SBFD configuration information. The conflict may include at least one of the following:

[0207] A time domain unit is indicated as an SBFD time domain unit based on the Common SBFD configuration information, while the time domain unit is indicated as a non-SBFD time domain unit based on the Dedicated SBFD configuration information.

[0208] A certain time domain unit is indicated as a non-SBFD time domain unit based on the Common SBFD configuration information, while the same time domain unit is indicated as an SBFD time domain unit based on the Dedicated SBFD configuration information.

[0209] In operation 2 above, the dedicated SBFD configuration information only serves as a supplement to the common SBFD configuration information. Determining the second SBFD configuration information as the effective SBFD configuration information includes at least one of the following items 1 to 3:

[0210] Item 1: when the general SBFD configuration information indicates a first SBFD resource, the terminal-specific SBFD configuration information indicates a second SBFD resource, and at least some of the second SBFD resources are different from the first SBFD resources, determining that the second SBFD configuration information is the effective SBFD configuration information;

[0211] Here, both the Common SBFD configuration information and the Dedicated SBFD configuration information are complete configuration information, and the Dedicated SBFD configuration information may further indicate additional / supplementary SBFD resources based on the SBFD resources indicated by the Common SBFD configuration information (eg, the set of indicated SBFD time domain units).

[0212] For example, the dedicated SBFD configuration information may further indicate some non-SBFD time domain units as SBFD time domain units based on the SBFD time domain units indicated by the common SBFD configuration information.

[0213] Conflicts between dedicated SBFD configuration information and common SBFD configuration information are not permitted. For example, when a time domain unit is indicated as an SBFD time domain unit based on common SBFD configuration information, it cannot be further indicated as a non-SBFD time domain unit based on dedicated SBFD configuration information. (Alternatively, when a DL time domain unit is indicated as an SBFD time domain unit based on common SBFD configuration information, it cannot be further indicated as a non-SBFD time domain unit based on dedicated SBFD configuration information; and when a flexible time domain unit is indicated as an SBFD time domain unit based on common SBFD configuration information, it cannot be further indicated as a non-SBFD time domain unit based on dedicated SBFD configuration information.) For an SBFD time domain unit indicated based on common SBFD configuration information, if dedicated SBFD configuration information explicitly indicates this SBFD time domain unit, the subband configuration information indicated for this SBFD time domain unit by the common SBFD configuration information and the dedicated SBFD configuration information must be completely consistent. For the SBFD time domain unit further indicated based on the dedicated SBFD configuration information (ie, the common SBFD configuration information does not indicate this SBFD time domain unit), the subband configuration information indicated for it is required to be completely consistent with the subband configuration information indicated in the common SBFD configuration information, or no restriction is imposed.

[0214] Item 2: When the general SBFD configuration information includes time domain configuration information of an SBFD time domain unit, and the terminal-specific SBFD configuration information includes subband configuration information within the SBFD time domain unit, determining that the second SBFD configuration information is the effective SBFD configuration information;

[0215] Item 3: When the general SBFD configuration information includes subband configuration information in an SBFD time domain unit, and the terminal-specific SBFD configuration information includes time domain configuration information of the SBFD time domain unit, determining that the second SBFD configuration information is the effective SBFD configuration information.

[0216] For the second and third items above, both the Common SBFD configuration information and the Dedicated SBFD configuration information are incomplete configuration information. Only when the two are combined can the time-frequency positions of the UL subband, DL subband, Guardband, etc. be completely determined.

[0217] Optionally, the method of the embodiment of the present application further includes:

[0218] The terminal performs the second operation based on third SBFD configuration information and universal time division duplex (TDD) mode configuration information, where the third SBFD configuration information includes the first SBFD configuration information, or includes effective SBFD configuration information determined based on the first SBFD configuration information. Optionally, the effective SBFD configuration information may be determined by the first operation. The effective SBFD configuration information may also be described as SBFD configuration information actually applied by the terminal.

[0219] In the embodiment of the present application, the terminal that performs the second operation may be a UE in RRC_CONNECTED mode and / or RRC_IDLE / INACTIVE mode, or in other words, it may be a UE in RRC_CONNECTED mode and / or RRC_IDLE / INACTIVE mode.

[0220] When SBFD is introduced primarily to improve uplink capacity, latency, coverage, and other performance, SBFD is primarily applied to DL symbols and / or Flexible symbols determined based on the Common TDD pattern configuration information (i.e., the tdd-UL-DL-ConfigurationCommon provided for the CC / Serving cell applying SBFD). Upon receiving the SBFD configuration information, the UE may perform the second operation described above.

[0221] The second operation includes at least one of the following first and second items:

[0222] Item 1: The terminal expects that the target SBFD time domain unit does not include time domain units other than the time domain units in the first time domain unit or does not overlap with time domain units other than the time domain units in the first time domain unit, that is, the terminal expects that the target SBFD time domain unit only includes time domain units in the first time domain unit or only overlaps with time domain units in the first time domain unit, and the target SBFD time domain unit is a time domain unit determined based on the third SBFD configuration information, and the first time domain unit includes at least one of a downlink time domain unit and a flexible time domain unit determined according to the general TDD mode configuration information; for example, the UE expects that the SBFD time domain unit determined by the SBFD configuration information does not cover other symbols except the DL symbol and / or Flexible symbol, or does not overlap with other symbols except the DL symbol and / or Flexible symbol in the time domain. It can also be understood that when the network side provides the SBFD configuration information, it needs to ensure that the above requirements are met.

[0223] Item 2: The terminal determines that the time domain units in the first time domain units included in the target SBFD time domain unit are time domain units that can perform SBFD operations, or determines that the time domain units in the first time domain units overlapping with the target SBFD time domain unit are time domain units that can perform SBFD operations. For example, the UE only considers that the Subband configuration information corresponding to the SBFD configuration information is valid (i.e., the SBFD operation can be performed therein) within the DL symbol and / or Flexible symbol covered or overlapped by the SBFD time domain unit determined by the SBFD configuration information. It can also be understood that the UE considers that in the Symbol covered or overlapped by the SBFD time domain unit determined by the SBFD configuration information, except for the Subband configuration information being valid in all DL symbols and / or Flexible symbols, the Subband configuration information is actually not valid in other Symbols (or the UE ignores these other Symbols when determining the time domain position where the SBFD operation can be performed).

[0224] Optionally, the method of the embodiment of the present application further includes: Dedicated TDD pattern interaction mode 1 or Dedicated TDD pattern interaction mode 2;

[0225] Dedicated TDD pattern interaction mode 1: the terminal does not expect dedicated TDD mode configuration information to be provided for the terminal;

[0226] In the interaction mode 1, when SBFD configuration information has been provided to a certain CC / Serving cell for the UE, the UE does not expect to further provide Dedicated TDD pattern configuration information for this CC / Serving cell.

[0227] At this time, all SBFD capable / aware UEs served by this CC / Serving cell share the same TDD pattern configuration information (ie, Common TDD pattern configuration information), and interaction between SBFD configuration information and Dedicated TDD pattern configuration information is avoided.

[0228] Dedicated TDD pattern interaction mode 2: The terminal performs a third operation based on third SBFD configuration information, where the third SBFD configuration information includes the first SBFD configuration information or includes effective SBFD configuration information determined based on the first SBFD configuration information.

[0229] In the interaction mode 2, when SBFD configuration information has been provided to the UE for a CC / Serving cell, if Dedicated TDD pattern configuration information is also provided for this CC / Serving cell, the interaction operation between the SBFD configuration information and the Dedicated TDD pattern configuration information is performed, that is, the third operation mentioned above.

[0230] Assuming that the Dedicated TDD pattern configuration information cannot modify the DL / UL symbol determined based on the Common TDD pattern configuration information, the interactive operation here is mainly for the Flexible symbol determined based on the Common TDD pattern configuration information (or when the Common TDD pattern configuration information is not provided, all Symbols are assumed to use the corresponding operations of the Flexible symbol, or, also referred to as the Flexible symbol), and, based on the SBFD configuration information, SBFD is applied in this Symbol (that is, this Symbol is covered by the SBFD time domain unit determined based on the SBFD configuration information, or, overlaps with the SBFD time domain unit determined based on the SBFD configuration information in the time domain). These Symbols are subsequently referred to as Common flexible symbols configured with SBFD.

[0231] The third operation includes at least one of the following first to third items:

[0232] Item 1: The terminal expects that the time domain unit indicated by the dedicated TDD mode configuration information does not include the second time domain unit or does not overlap with the second time domain unit, wherein the second time domain unit is a flexible time domain unit capable of performing SBFD operations determined based on the third SBFD configuration information; for example, the UE expects that the Symbol indicated by the Dedicated TDD pattern configuration information does not cover the Common flexible symbol configured with SBFD, or does not overlap with the Common flexible symbol configured with SBFD in the time domain. It can also be understood that when the network side provides the Dedicated TDD pattern configuration information, it needs to ensure that the above requirements are met.

[0233] Item 2: The terminal expects the third time domain unit to be indicated as a flexible time domain unit by the dedicated TDD mode configuration information, and the third time domain unit is a time domain unit that overlaps with the second time domain unit in the time domain unit indicated by the dedicated TDD mode configuration information; for example, the terminal expects the overlapping Symbol to still be indicated as a Flexible symbol by the Dedicated TDD pattern configuration information. It can be understood that the SBFD behavior within these overlapping Symbols is also not affected (that is, the UE still performs the SBFD operation for the Flexible symbol within the overlapping Symbol).

[0234] Item 3: The terminal determines that the indication of the dedicated TDD mode configuration information for the direction of the third time domain unit is not effective, or the terminal ignores the indication of the dedicated TDD mode configuration information for the direction of the third time domain unit, or the terminal determines that the indication of the dedicated TDD mode configuration information for the direction of the third time domain unit is effective. It can be understood that the SBFD behavior within the third time domain unit is also unaffected (i.e., the UE still performs the SBFD operation for the Flexible symbol in the overlapping third time domain unit).

[0235] Optionally, the terminal determines that the indication of the direction of the third time domain unit by the dedicated TDD mode configuration information is effective, including one of the following first to sixth items:

[0236] Item 1: when the third time domain unit is indicated by the dedicated TDD mode configuration information as a flexible time domain unit, determining that an SBFD operation for the flexible time domain unit can be performed in the third time domain unit;

[0237] Item 2: when the third time domain unit is indicated by the dedicated TDD mode configuration information as a downlink time domain unit, determining that an SBFD operation for the downlink time domain unit can be performed in the third time domain unit; or determining the third time domain unit as a downlink time domain unit and determining the third time domain unit as a time domain unit that does not perform an SBFD operation;

[0238] Item 3: When the third time domain unit is indicated as a downlink time domain unit by the dedicated TDD mode configuration information, determining that downlink reception can only be performed within the downlink subband within the third time domain unit;

[0239] Item 4: when the third time domain unit is indicated as a downlink time domain unit by the dedicated TDD mode configuration information, determining that the third time domain unit is a downlink time domain unit, and an SBFD operation cannot be performed in the third time domain unit;

[0240] Item 5: When the third time domain unit is indicated as an uplink time domain unit by the dedicated TDD mode configuration information, determining that uplink transmission can only be performed within the uplink subband within the third time domain unit;

[0241] Item 6: When the third time domain unit is indicated as an uplink time domain unit by the dedicated TDD mode configuration information, determine that the third time domain unit is an uplink time domain unit, and SBFD operation cannot be performed in the third time domain unit.

[0242] In the embodiment of the present application, for the case where the above-mentioned terminal determines that the indication of the direction of the dedicated TDD mode configuration information for the third time domain unit is effective, it can be further distinguished from at least one of the following cases 1 to 3 and perform corresponding operations respectively (here it is assumed that the SCS corresponding to the Common TDD pattern configuration information and the Dedicated TDD pattern configuration information are the same, then the overlapping time domain units (using symbols as an example) are actually completely overlapped; for the sake of simplicity, the following description is regarded as the same Symbol):

[0243] Case 1: When a Common flexible symbol configured with SBFD is indicated as a Flexible symbol by the Dedicated TDD pattern configuration information, the SBFD behavior within this Symbol is not affected (ie, the UE still performs SBFD operations for the Flexible symbol within this Symbol).

[0244] Case 2: When a Common flexible symbol configured with SBFD is indicated as a DL symbol by the Dedicated TDD pattern configuration information, this symbol is rewritten as a DL symbol. At this time, the UE performs SBFD operation for the DL symbol within this symbol, or the UE uses this symbol as a DL-only symbol (or Full DL symbol) and no longer performs SBFD operation; or this symbol remains a Flexible symbol, and the UE can still perform SBFD operation for the Flexible symbol within this symbol, but downlink reception is only allowed within the DL subband of this symbol.

[0245] Case 3: When a Common flexible symbol configured with SBFD is indicated as a UL symbol by the Dedicated TDD pattern configuration information, this symbol is rewritten as a UL symbol. At this time, the UE uses this symbol as a UL only symbol (or Full UL symbol) and no longer performs SBFD operation; alternatively, this symbol remains a Flexible symbol, and the UE can still perform SBFD operation for the Flexible symbol within this symbol, but uplink transmission is only allowed within the UL subband of this symbol.

[0246] Optionally, the UE expects that a certain Common flexible symbol configured with SBFD is only indicated as a Flexible symbol or a DL symbol by Dedicated TDD pattern configuration information.

[0247] Optionally, the UE does not expect a certain Common flexible symbol configured with SBFD to be indicated as a UL symbol by Dedicated TDD pattern configuration information.

[0248] The terminal in the above-mentioned Dedicated TDD pattern interaction mode 1 and Dedicated TDD pattern interaction mode 2 may be a UE in RRC_CONNECTED mode.

[0249] Optionally, the method of the embodiment of the present application further includes:

[0250] The terminal does not expect to configure slot format indication (SFI) monitoring for the first object, and the terminal is a UE in RRC_CONNECTED mode; when SBFD configuration information has been provided to the UE for a certain CC / Serving cell, the UE does not expect to further configure SFI monitoring for this CC / Serving cell (for example, configure monitoring of DCI format2_0). At this time, the interaction between the SBFD configuration information and the SFI indication information is avoided for this CC / Serving cell.

[0251] Alternatively, when SFI monitoring is configured for the first object and SFI is detected, the terminal performs a fourth operation according to third SBFD configuration information, where the third SBFD configuration information includes the first SBFD configuration information or includes effective SBFD configuration information determined based on the first SBFD configuration information;

[0252] Alternatively, when SFI monitoring is configured for the first object and no SFI is detected for at least one time domain unit, the terminal performs a fifth operation according to the third SBFD configuration information;

[0253] The terminal that performs the fourth operation and the fifth operation is a UE in RRC_CONNECTED mode.

[0254] It is assumed that based on the SBFD configuration information provided for this CC / Serving cell, as well as the Common TDD pattern configuration information and / or Dedicated TDD pattern configuration information, the Symbol to which SBFD is applied is determined to be a Symbol configured with SBFD; when a Symbol configured with SBFD is determined to be a DL symbol based on the Common TDD pattern configuration information and / or Dedicated TDD pattern configuration information, it can be called a Semi-static DL symbol configured with SBFD; when a Symbol configured with SBFD is determined to be a Flexible symbol based on the Common TDD pattern configuration information and / or Dedicated TDD pattern configuration information, it can be called a Semi-static flexible symbol configured with SBFD.

[0255] The fourth operation includes at least one of the following first to third items:

[0256] Item 1: The terminal expects that the time domain unit indicated by the SFI does not include the fourth time domain unit or does not overlap with the fourth time domain unit, and the fourth time domain unit is an SBFD time domain unit determined based on the first configuration information and the second SBFD configuration information, and the first configuration information includes at least one of the general TDD mode configuration information and the dedicated TDD mode configuration information; for example, the UE expects that the Symbol indicated by the SFI indication information does not include the Symbol configured with SBFD, or does not overlap with the Symbol configured with SBFD in the time domain. It can also be understood that when the network side provides the SFI indication information, it needs to ensure that the above requirements are met.

[0257] Item 2: The terminal expects that the direction of the fifth time domain unit indicated by the SFI is consistent with the direction of the fifth time domain unit determined based on the first configuration information, and the fifth time domain unit is the time domain unit in the time domain unit indicated by the SFI that overlaps with the fourth time domain unit; for example, when the Symbol indicated by the SFI indication information covers the Symbol configured with SBFD or overlaps with the Symbol configured with SBFD in the time domain, the UE expects the direction indicated by the SFI indication information for these overlapping Symbols to be completely consistent with the direction determined based on the Common TDD pattern configuration information and / or the Dedicated TDD pattern configuration information. It can be understood that the SBFD behavior within these overlapping Symbols is also not affected (that is, the UE still performs the SBFD operation for the DL / Flexible symbol in the overlapping Symbol based on the direction determined by the Common TDD pattern configuration information and / or the Dedicated TDD pattern configuration information).

[0258] Item 3: The terminal determines that the indication of the direction of the fifth time domain unit by the SFI is not effective, or the terminal ignores the indication of the direction of the fifth time domain unit by the SFI, or the terminal determines that the indication of the direction of the fifth time domain unit by the SFI is effective;

[0259] For example, the UE considers that the direction rewriting (if any) of the SFI indication information for these overlapping symbols is not effective, or the UE ignores the indication of the SFI indication information for these overlapping symbols. It can be understood that the SBFD behavior within these overlapping symbols is also not affected (that is, the UE still performs the SBFD operation for the DL / Flexible symbol in the overlapping symbols based on the direction determined by the Common TDD pattern configuration information and / or the Dedicated TDD pattern configuration information).

[0260] Optionally, when the terminal determines that the SFI indication of the direction of the fifth time domain unit is effective, it can distinguish at least one of the following cases 1 to 6 and perform corresponding operations respectively (here it is assumed that the SFI indication information is the same as the SCS corresponding to the Common TDD pattern configuration information and / or the Dedicated TDD pattern configuration information, then the overlapping time domain units (using Symbol as an example) are actually completely overlapped; for simplicity of description, they are regarded as the same Symbol below):

[0261] Case 1: When the fifth time domain unit is determined to be a downlink time domain unit based on the first configuration information, and the fifth time domain unit is indicated as a downlink time domain unit by the SFI, it is determined that the SBFD operation for the downlink time domain unit can be performed in the fifth time domain unit; for example, when a semi-static DL symbol configured with SBFD is indicated as a DL symbol by the SFI indication information, the SBFD behavior within this symbol is not affected (that is, the UE still performs the SBFD operation for the DL symbol within this symbol);

[0262] Case 2: When the fifth time domain unit is determined to be a flexible time domain unit based on the first configuration information, and the fifth time domain unit is indicated as a flexible time domain unit by the SFI, it is determined that the SBFD operation for the flexible time domain unit can be performed in the fifth time domain unit; for example, when a semi-static flexible symbol configured with SBFD is indicated as a flexible symbol by the SFI indication information, the SBFD behavior within this symbol is not affected (that is, the UE still performs the SBFD operation for the flexible symbol within this symbol);

[0263] Case 3: When the fifth time domain unit is determined to be a flexible time domain unit based on the first configuration information, and the fifth time domain unit is indicated by the SFI as a downlink time domain unit, it is determined that the SBFD operation for the downlink time domain unit can be performed in the fifth time domain unit; for example, when a semi-static flexible symbol configured with SBFD is indicated as a DL symbol by the SFI indication information, the SBFD behavior within this symbol may be affected to a certain extent (ie, the UE performs the SBFD operation for the DL symbol in this symbol instead);

[0264] Case 4: When the fifth time domain unit is determined to be a flexible time domain unit based on the first configuration information, and the fifth time domain unit is indicated by SFI as a downlink time domain unit, it is determined that downlink reception can only be performed in the downlink subband within the fifth time domain unit; for example, when a semi-static flexible symbol configured with SBFD is indicated as a DL symbol by the SFI indication information, the SBFD behavior within this symbol is affected to a certain extent (that is, the UE still performs the SBFD operation for the flexible symbol within this symbol, but is only allowed to perform downlink reception in the DL subband of this symbol);

[0265] Case 5: When the fifth time domain unit is determined to be a flexible time domain unit based on the first configuration information, and the fifth time domain unit is indicated by SFI as an uplink time domain unit, the fifth time domain unit is determined to be an uplink time domain unit, and the SBFD operation cannot be performed in the fifth time domain unit; for example, when a semi-static flexible symbol configured with SBFD is indicated as a UL symbol by the SFI indication information, this symbol is rewritten as a UL symbol. At this time, the UE uses this symbol as a UL only symbol (or Full UL symbol) and no longer performs the SBFD operation;

[0266] Case 6: When the fifth time domain unit is determined to be a flexible time domain unit based on the first configuration information, and the fifth time domain unit is indicated by SFI as an uplink time domain unit, it is determined that uplink transmission can only be performed within the uplink subband within the fifth time domain unit; for example, when a Semi-static flexible symbol configured with SBFD is indicated as a UL symbol by SFI indication information, the SBFD behavior within this Symbol is affected to a certain extent (that is, the UE still performs the SBFD operation for the Flexible symbol within this Symbol, but uplink transmission is only allowed within the UL subband of this Symbol).

[0267] Optionally, the UE expects that a certain Semi-static DL symbol configured with SBFD is only indicated as a DL symbol by SFI indication information, or is not indicated as a Flexible symbol or a UL symbol.

[0268] Optionally, the UE expects that a certain Semi-static flexible symbol configured with SBFD is only indicated as a Flexible symbol or a DL symbol by SFI indication information, or is not indicated as a UL symbol.

[0269] The fifth operation includes at least one of the following first to fourth items:

[0270] Item 1: When at least one sixth time domain unit is included in the at least one time domain unit, determining that an SBFD operation can be performed in the sixth time domain unit; the sixth time domain unit includes a downlink time domain unit determined based on the first configuration information and the second SBFD configuration information; for example, when SFI monitoring is configured for a first object and no SFI is detected for at least one Symbol, when the at least one Symbol includes at least one Semi-static DL symbol configured with SBFD, the SBFD behavior within the Semi-static DL symbol configured with SBFD is unaffected (i.e., the UE still performs the SBFD operation for the DL symbol within the Symbol);

[0271] Item 2: When at least one seventh time domain unit is included in the at least one time domain unit, it is determined that a first SBFD operation can be performed in the seventh time domain unit, and the transmission corresponding to the first SBFD operation includes the transmission of the high-level configuration and the transmission indicated by the downlink control information DCI; wherein the seventh time domain unit includes a flexible time domain unit determined based on the first configuration information and the second SBFD configuration information. For example, the above-mentioned seventh time domain unit is a semi-static flexible symbol configured with SBFD, and the UE still normally performs the SBFD operation for the flexible symbol in this semi-static flexible symbol configured with SBFD, and allows the transmission of the SBFD operation including the transmission of the high-level configuration and the transmission of the DCI dynamic indication (which is completely consistent with the SBFD operation for the flexible symbol when SFI monitoring is not configured);

[0272] Item 3: Cancel or stop the transmission of the high-level configuration, and determine that the second SBFD operation can be performed within the seventh time domain unit, the second SBFD operation including the SBFD operation for the flexible time domain unit indicated by the DCI; wherein the seventh time domain unit includes a flexible time domain unit determined based on the first configuration information and the second SBFD configuration information, for example, the above-mentioned seventh time domain unit is a Semi-static flexible symbol configured with SBFD, and the UE Cancel / Drops the transmission of the high-level configuration within this Semi-static flexible symbol configured with SBFD, and can only perform the SBFD operation for the Flexible symbol for the transmission dynamically indicated by the DCI.

[0273] Item 4: Determine that the SBFD operation cannot be performed within the seventh time domain unit; wherein the seventh time domain unit includes a flexible time domain unit determined based on the first configuration information and the second SBFD configuration information, for example, the above-mentioned seventh time domain unit is a Semi-static flexible symbol configured with SBFD, and the UE no longer performs the SBFD operation for the Flexible symbol in this Semi-static flexible symbol configured with SBFD, and continues to use the Legacy behavior for the Semi-static flexible symbol (that is, the transmission configured by the higher layer is canceled (Cancel) / stopped (Drop), and the transmission dynamically indicated by the DCI can be transmitted normally, but can only correspond to a single transmission direction and cannot be used for SBFD);

[0274] The above-mentioned SFI can be understood as a slot format indication indicated by DCI format 2_0, which dynamically indicates the slot format applied to each slot of a CC / Serving cell within a period of time.

[0275] In an embodiment of the present application, through the first SBFD configuration information, and the interaction between the first SBFD configuration information and TDD-related configuration information (such as Common TDD pattern configuration information, Dedicated TDD pattern configuration information, SFI), the deployment of SBFD operations in the TDD network can be effectively guaranteed, and the uplink capacity, latency, coverage and other performance can be effectively improved.

[0276] As shown in FIG4 , the embodiment of the present application further provides an information processing method, including:

[0277] Step 401: A network-side device sends first sub-band full-duplex SBFD configuration information, where the first SBFD configuration information includes at least one of general SBFD configuration information and terminal-specific SBFD configuration information.

[0278] Among them, the general SBFD configuration information is the SBFD information uniformly configured for all terminals of the first object service and / or the SBFD information applied to all terminals of the first object service, and the terminal-specific SBFD configuration information is the SBFD information independently configured for the terminal of the first object service and / or the SBFD information applied to the terminal of the first object service.

[0279] Optionally, the first object includes at least one of a component carrier, a serving cell, and a bandwidth part BWP.

[0280] Optionally, the network-side device sends the first SBFD configuration information via RRC signaling or SIB. Exemplarily, the SIB may be SIB1, and the RRC signaling may be an RRC reconfiguration message or an RRC release message.

[0281] In an embodiment of the present application, the network side device sends the first sub-band full-duplex SBFD configuration information, and the first SBFD configuration information includes at least one of general SBFD configuration information and terminal-specific SBFD configuration information. Through the above-mentioned general SBFD configuration information, it is possible to obtain the SBFD information uniformly configured for all terminals of the first object service and / or obtain the SBFD information applied by all terminals of the first object service. Through the above-mentioned terminal-specific SBFD configuration information, it is possible to obtain the SBFD information independently configured for the terminal of the first object service and / or obtain the SBFD information applied by the terminal of the first object service. Thus, through the first SBFD configuration information, the terminal of the first object service can obtain the corresponding SBFD configuration information, so that the terminal of the first object service can perform the SBFD operation corresponding to the SBFD configuration information, thereby effectively ensuring the deployment of SBFD operations in the TDD network, and then effectively improving the uplink capacity, latency, coverage and other performance.

[0282] Optionally, sending the first sub-band full-duplex SBFD configuration information includes:

[0283] Sending a radio resource control (RRC) release message; wherein the RRC release message indicates at least one set of SBFD configuration information, each set of SBFD configuration information being applicable to all objects that meet the applicable conditions corresponding to the SBFD configuration information; or, the RRC release message indicates at least one object and a set of SBFD configuration information applicable to each of the objects;

[0284] The SBFD configuration information indicated by the RRC release includes first SBFD configuration information applicable to the first object.

[0285] In the embodiment of the present application, the RRC release message is used to transfer the UE from the RRC connected mode (RRC_CONNECTED mode) to the RRC idle state or inactive mode (RRC_IDLE / INACTIVE mode).

[0286] The solution of sending the first sub-band full-duplex SBFD configuration information through the RRC release message has been described in detail in the method embodiment on the terminal side and will not be repeated here.

[0287] Optionally, the applicable conditions include at least one of the following (a) to (e):

[0288] (a) belongs to a designated public land mobile network (PLMN);

[0289] (b) located in a designated frequency layer;

[0290] (c) located within a designated area;

[0291] (d) Not in the Reserved state or the Barred state;

[0292] (e) Indicated in the RRC release message.

[0293] The applicable conditions have been described in detail in the method embodiment on the terminal side and will not be repeated here.

[0294] Optionally, the method of the embodiment of the present application further includes:

[0295] In a contention-based random access process, determining the terminal-specific SBFD configuration information in the first SBFD configuration information based on the first correspondence relationship or based on the first correspondence relationship and the second correspondence relationship;

[0296] The first corresponding relationship is the corresponding relationship between the terminal-specific SBFD configuration information and the random access opportunity RO, and the second corresponding relationship is the corresponding relationship between the terminal-specific SBFD configuration information and the preamble code set.

[0297] In the first correspondence, the terminal-specific SBFD configuration information and the RO may correspond one-to-one, or at least one RO may correspond to multiple sets of different terminal-specific SBFD configuration information.

[0298] The uplink resources determined based on the above terminal-specific SBFD configuration information can be used for PRACH transmission, PUSCH transmission corresponding to Msg3 / MsgA, PUCCH transmission corresponding to HARQ-ACK of Msg4 / MsgB, etc.

[0299] In an embodiment of the present application, when the UE uses uplink resources determined based on the dedicated SBFD configuration information in a contention-based random access process (including a scenario of initial access to a cell) (for example, for PRACH transmission, PUSCH transmission corresponding to Msg3 / MsgA, PUCCH transmission corresponding to HARQ-ACK of Msg4 / MsgB, etc.), the network side may distinguish different dedicated SBFD configuration information corresponding to each UE based on any one of the following SBFD configuration information identification mode 1 and SBFD configuration information identification mode 2:

[0300] SBFD configuration information identification method 1: for independent RO (Separate RO);

[0301] The network side independently configures the RO for the uplink resources in each set of Dedicated SBFD configuration information (assuming that the ROs corresponding to the different sets of Dedicated SBFD configuration information do not overlap with each other; for example, when a block of time-frequency resources is mapped to the RO corresponding to a certain set of Dedicated SBFD configuration information, this block of time-frequency resources is not allowed to be mapped to the RO corresponding to another set of Dedicated SBFD configuration information). Based on the correspondence between the RO and the Dedicated SBFD configuration information, the Dedicated SBFD configuration information corresponding to the UE sending the preamble in a certain RO can be determined. Generally, to simplify configuration, each set of Dedicated SBFD configuration information can correspond to an independent SSB to RO mapping.

[0302] SBFD configuration information identification method 2: for shared RO (Shared RO);

[0303] Among the ROs that can be used by UEs applying different dedicated SBFD configuration information, at least one RO overlaps (for example, at least one RO corresponds to multiple different sets of dedicated SBFD configuration information).

[0304] One possible implementation is: assuming that the Common SBFD configuration information is notified in a cell broadcast (e.g., SIB1), and the UE can determine the initial RO and the initial SSB to RO mapping based on this Common SBFD configuration information (at this time, the initial SSB to RO mapping determined by all SBFD-aware UEs or SBFD-capable UEs are completely consistent). The UE further determines its actually available RO based on predefined rules. For example, based on the interaction between the Common SBFD configuration information and the Dedicated SBFD configuration information (for a detailed description, see below), when a certain RO does not completely fall within the time domain unit to which a valid RO can be mapped (including the uplink time domain unit and the determined SBFD time domain unit, etc.), the UE determines that the RO is actually unavailable; when a certain RO completely falls within the time domain unit to which a valid RO can be mapped and overlaps with the determined SBFD time domain unit, the UE determines that it is actually available only when it is completely located within the UL subband determined to be applied within this determined SBFD time domain unit. For another example, the UE determines whether a certain initial RO is actually available based on the RO Mask (combined with / indicated simultaneously with the Dedicated SBFD configuration information) (further, the UE expects that this RO falls completely within the time domain unit to which the valid RO can be mapped, and when there is an overlap with the determined SBFD time domain unit, it is completely located within the UL subband determined for application within the overlapping SBFD time domain unit).

[0305] In order to further distinguish UEs that use resources within the same RO but correspond to different dedicated SBFD configuration information, corresponding preamble subsets can be indicated for different dedicated SBFD configuration information (that is, in the same RO, mutually orthogonal preamble subsets are used); based on the correspondence between the preamble and the dedicated SBFD configuration information, the network side can determine the dedicated SBFD configuration information corresponding to the UE sending the preamble in this RO.

[0306] After the network side detects the Preamble sent by a UE and identifies its corresponding Dedicated SBFD configuration information, it can indicate appropriate time-frequency resources for the subsequent uplink transmission of the random access process based on this Dedicated SBFD configuration information.
