It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0038] In addition, to facilitate understanding of the technical solutions provided by this application, the relevant technical features involved are explained below.

[0039] (1) Bandwidth Part (BWP)

[0040] Mobile communication systems need to adapt to increasingly diverse scenarios and service requirements. For example, key 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). These scenarios place high demands on mobile communication systems for reliability, low latency, high bandwidth, and wide coverage. Terminals require different transmission bandwidths for different application scenarios.

[0041] In NR, the base station can schedule terminals to transmit on different BWPs based on demand. In NR, the network configures one or more BWPs for the UE for data transmission. A BWP is a continuous range of resources in the frequency domain. The UE dynamically changes bandwidth by activating different BWPs. As shown in Figure 1b, at the first moment T1, if the UE's traffic volume is large, the UE can activate a large bandwidth, such as DL BWP1. At the second moment T2, if the UE's traffic volume is small, the UE can activate a small bandwidth, such as DL BWP2, to meet basic communication needs. At the third moment T3, if the network detects large-scale frequency selective fading within the bandwidth of DL BWP1, or if resources are relatively scarce within the frequency range of DL BWP2, the UE can be instructed to activate a new bandwidth, such as DL BWP3.

[0042] The configuration of BWP is configured through specific UE (UE-specific) parameters. Each BWP can correspond to different configuration parameters, which may include subcarrier spacing (SCS), BWP location and bandwidth, cyclic prefix (CP), etc.

[0043] It is worth noting that the network side can configure up to 4 dedicated BWPs for the UE's DL / UL respectively.

[0044] (2) Duplex mode

[0045] 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 transmission and downlink reception occur on different frequencies, allowing them to operate simultaneously without interfering with each other. In TDD, uplink transmission and downlink reception occur on the same frequency, interleaved using time division. Each duplex mode has its advantages and disadvantages. The following briefly describes full duplex on the network side and half duplex or full duplex on the terminal side.

[0046] (a) Full-duplex on the network side

[0047] From the network's perspective, uplink transmission and downlink reception can occur simultaneously within different frequency sub-bands at the same time. To prevent interference between uplink and downlink, a guard band (Guard Band) can be reserved between frequency sub-bands corresponding to different transmission directions (e.g., uplink and downlink sub-bands).

[0048] (b) Half-duplex or full-duplex on the terminal side

[0049] When the terminal supports half-duplex, only uplink transmission or downlink reception can be performed at the same time, not both. It is understood that in this case, if the network performs uplink reception and downlink transmission simultaneously, the uplink transmission and downlink reception at the same time on the network side can only be for different terminals.

[0050] When the terminal side supports full-duplex, similar to the network side, at the same time, uplink transmission and downlink reception can be performed simultaneously in different frequency sub-bands.

[0051] Based on this, the technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0052] FIG2 is a flow chart of a communication method 200 according to an exemplary embodiment of the present application. This method 200 may be, but is not limited to, executed by a terminal, specifically by at least one of hardware and software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0053] S210: The terminal obtains resource configuration information from a network-side device.

[0054] The resource configuration information may include but is not limited to at least one of time domain resource configuration information and frequency domain resource configuration information corresponding to SBFD. The SBFD may include network-side full-duplex, terminal-side half-duplex, or full-duplex.

[0055] In one implementation, for the terminal, a maximum of two sets of time division multiplexing uplink / downlink modes (TDD-UL-DL-Pattern, or time division multiplexing uplink / downlink format) can be configured in one terminal. Then, in this embodiment, when configuring the time domain resource configuration information corresponding to SBFD, the configuration can be performed for TDD-UL-DL-Pattern, such as the network side device can configure the SBFD time domain unit in each TDD-UL-DL-Pattern through but not limited to high-layer signaling, such as downlink time slot or symbol (DL slot or symbol), flexible time slot or symbol (flexible slot or symbol), uplink time slot or symbol (UL slot or symbol), wherein the high-layer signaling can be but not limited to cell-specific signaling, etc.

[0056] In this embodiment, the time domain resource configuration information may be configured with a single TDD-UL-DL-Pattern as the granularity, i.e., the time domain resource configuration information corresponds one-to-one with the TDD-UL-DL-Pattern. For example, if the terminal is configured with two sets of TDD-UL-DL-Pattern, then the time domain resource configuration information may also be two sets.

[0057] Alternatively, the time domain resource configuration information may also be configured with multiple TDD-UL-DL-Pattern granularity, that is, one piece of time domain resource configuration information may correspond to multiple TDD-UL-DL-Pattern.

[0058] Based on this, in an optional implementation, the time domain resource configuration information may include but is not limited to at least one of the following 101)-111).

[0059] 101) An index of a starting time slot corresponding to the SBFD time domain resource, used to indicate a position of a starting time slot in which the terminal can perform SBFD transmission.

[0060] 102) An index of a starting symbol in a starting time slot corresponding to the SBFD time domain resource, to indicate a position of a starting symbol at which the terminal can perform SBFD transmission.

[0061] 103) The number of symbols used for the SBFD transmission in the starting time slot corresponding to the SBFD time domain resource.

[0062] Among them, if the number of symbols used for the SBFD transmission in the starting time slot is n, then the number of symbols used for the SBFD transmission in the starting time slot corresponding to the SBFD time domain resource can be counted from the last symbol in the starting time slot corresponding to the SBFD time domain resource to the first symbol by n symbols to determine the starting symbol position for the SBFD transmission.

[0063] For example, assuming that the number of symbols used for the SBFD transmission in the starting time slot corresponding to the SBFD time domain resource is 3, the number of symbols contained in a slot is 14, and the symbol indexes are 0, 1,..., 13 respectively, then the index of the starting symbol of the symbols used for the SBFD transmission in the starting time slot corresponding to the SBFD time domain resource is 11.

[0064] 104) The number of time slots corresponding to non-SBFD time domain resources.

[0065] 105) The number of symbols corresponding to non-SBFD time domain resources.

[0066] With respect to 104)-105), it can be understood that in each TDD-UL-DL-Pattern, the resource arrangement in the time domain resource configuration corresponding to SBFD is generally non-SBFD time domain resources, SBFD time domain resources, and non-SBFD time domain resources. Therefore, in this embodiment, when configuring the time domain resources corresponding to SBFD, in addition to explicitly configuring the SBFD time domain resources, the SBFD time domain resources can also be implicitly configured by configuring non-SBFD time domain resources.

[0067] For example, assuming that the time domain resource configuration information includes the non-SBFD time domain resources described in 104)-105), then the terminal can determine the number of time slots and the number of symbols corresponding to the SBFD time domain resources based on the number of time slots and the number of symbols corresponding to the non-SBFD time domain resources.

[0068] 106) The number of consecutive time slots corresponding to the SBFD time domain resources.

[0069] As shown in Figure 3, assuming that some symbols in the starting time slot and the ending time slot corresponding to the SBFD time domain resource are configured as SBFD time domain resources, then the number of the continuous time slots is 3, that is, the continuous time slots do not include the starting time slot and the ending time slot, or the number of the continuous time slots is 5, that is, the continuous time slots include the starting time slot and the ending time slot.

[0070] 107) The number of consecutive symbols corresponding to the SBFD time domain resources.

[0071] 108) An index of the end slot corresponding to the SBFD time domain resource, used to indicate a position of the end slot in which the terminal can perform SBFD transmission.

[0072] 109) The number of symbols used for the SBFD transmission in the end slot corresponding to the SBFD time domain resource.

[0073] Among them, if the number of symbols used for the SBFD transmission in the end slot is m, then the number of symbols used for the SBFD transmission in the end slot corresponding to the SBFD time domain resource can be counted from the first symbol in the end slot corresponding to the SBFD time domain resource to the last symbol m symbols to determine the position of the end symbol used for the SBFD transmission.

[0074] For example, assuming that the number of symbols used for the SBFD transmission in the end slot corresponding to the SBFD time domain resource is 4, the number of symbols contained in a slot is 14, and the symbol indexes are 0, 1,..., 13 respectively, then the index of the end and start symbols of the symbols used for the SBFD transmission in the end slot corresponding to the SBFD time domain resource is 3.

[0075] 110) An index of an end symbol in an end slot corresponding to the SBFD time domain resource, used to indicate an end symbol when the terminal performs SBFD transmission.

[0076] 111) A first indicator value, used to indicate the number (or length) of the start symbol and consecutive symbols corresponding to the SBFD time domain resource. The first indicator value may be a start and length indicator value (SLIV), such as a Symbol level SLIV.

[0077] For example, for a SLIV value, it may correspond to a start symbol and a length of a continuation symbol. In this case, if Then SLIV is as shown in the following formula (1), and conversely, it is as shown in the following formula (2).

[0078] in, Indicates the total number of symbols in a configuration period (such as a TDD-UL-DL-Pattern) or the total number of symbols from the start time slot corresponding to the SBFD time domain resource to the last time slot of the configuration period (including the start time slot and the end time slot) in a configuration period (such as a TDD-UL-DL-Pattern).

[0079] L symbols represents the number of consecutive symbols in the configuration period (such as a TDD-UL-DL-Pattern),

[0080] N start Indicates the starting symbol index.

[0081] In some embodiments, when the first indicator value indicates that the starting symbol corresponding to the SBFD time domain resource is 0, that is, the SLIV value indicates S=0, then it can be determined that the starting symbol corresponding to the SBFD time domain resource is the first symbol in the TDD-UL-DL-Pattern. The numbering order of the entire symbol is from the first symbol corresponding to the TDD-UL-DL-Pattern to the last symbol.

[0082] Alternatively, when the first indication value indicates that the starting symbol corresponding to the SBFD time domain resource is 0, that is, the SLIV value indicates S=0, it can be determined that the starting symbol corresponding to the SBFD time domain resource is the first symbol in the starting time slot corresponding to the SBFD.

[0083] It is worth noting that, for each of the information in 101)-111) above, a variety of different ways of indicating the time domain resource configuration information can be achieved through the combination of different information.

[0084] For example, the time domain resource configuration information may include the information described in 201)-203) below.

[0085] 201) The index of the starting time slot corresponding to the SBFD time domain resource, the index of the starting symbol in the starting time slot, or the number of time slots and the number of symbols corresponding to the non-SBFD time domain resource.

[0086] 202) The number of consecutive time slots or the index of the end time slot corresponding to the SBFD time domain resource.

[0087] 203) The number of end symbols corresponding to the SBFD time domain resource, or the index of the end symbol in the end slot corresponding to the SBFD time domain resource.

[0088] Based on the information described in 201)-203), the terminal can accurately determine in which time slot or symbol the SBFD time domain resource starts and ends, thereby realizing time domain resource configuration during SBFD transmission.

[0089] For another example, the time domain resource configuration information may also only include the first indication information, such as SLIV at the Symbol level. Then, the terminal can directly determine at which symbol the SBFD time domain resource starts and ends based on the first indication information, thereby realizing the time domain resource configuration during SBFD transmission.

[0090] For example, the time domain resource configuration information may also include the index of the starting time slot corresponding to the SBFD time domain resource and the first indication information, or the time domain resource configuration information may also include the index of the starting time slot corresponding to the SBFD time domain resource, the index of the starting symbol in the starting time slot, and the number of consecutive symbols. Thus, the terminal can accurately determine in which time slot or symbol the SBFD time domain resource starts, and in which time slot or symbol it ends, thereby realizing the time domain resource configuration during SBFD transmission.

[0091] In addition, in some embodiments, if the starting time slot or symbol and the ending time slot or symbol corresponding to the SBFD time domain resource cannot be determined based on the aforementioned configured time domain resource configuration information, the starting time slot or symbol and the ending time slot or symbol may be configured in a combination of default or protocol-agreed manner. For example, if the time domain resource configuration information only configures the starting time slot corresponding to the SBFD time domain resource but does not configure the starting symbol, the starting symbol may be defaulted to a specific symbol within the starting time slot, such as the first symbol within the starting time slot; or, if the time domain resource configuration information only configures the ending time slot corresponding to the SBFD time domain resource but does not configure the ending symbol, the ending symbol may be defaulted to a specific symbol within the ending time slot, such as the last symbol within the ending time slot.

[0092] In this embodiment, through the configuration of the aforementioned time domain resource configuration information, the terminal can perform uplink transmission and downlink reception in the time domain unit configured as SBFD according to the time domain resource configuration information.

[0093] In addition, for the SBFD, in addition to the aforementioned time domain resource configuration information, frequency domain resource configuration information may also be configured, such as configuration of at least one of an uplink subband (UL subband), a downlink subband (DL subband), and a guard band, so that the terminal performs uplink transmission within the uplink subband and downlink reception within the downlink subband. It should be noted that the frequency domain resource configuration information for different time domain units (such as time slots or symbols) configured as SBFD can be the same.

[0094] Based on this, in some embodiments, the frequency domain resource configuration information may include but is not limited to at least one of the following 301)-304).

[0095] 301) A first reference SCS and information of a first object corresponding to the first reference SCS.

[0096] The first object may include but is not limited to at least one of an uplink subband, a downlink subband, and a guard band. The information of the first object may include but is not limited to at least one of the bandwidth of the first object (such as bandwidth size, bandwidth position, etc.), the starting physical resource block (PRB), the ending PRB, and the number of PRBs. The starting PRB may be indicated by a PRB index, and similarly, the ending PRB may also be indicated by a PRB index.

[0097] In addition, in some embodiments, the first reference SCS may be greater than the SCSs of all BWPs configured in the terminal. In other words, the terminal expects the first reference SCS corresponding to the uplink subband to be greater than or equal to the SCS of any uplink BWP configured for the terminal, and the terminal expects the first reference SCS corresponding to the downlink subband (or guard band) to be greater than or equal to the SCS of any downlink BWP configured for the terminal.

[0098] In some embodiments, the first reference SCS corresponding to the uplink subband and the first reference SCS corresponding to the downlink subband (or guard band) may be the same or different. For example, the base station configures the first reference SCS corresponding to the uplink subband and the first reference SCS corresponding to the downlink subband (or guard band) respectively.

[0099] 302) at least one second reference SCS, and information of the first object corresponding to each second reference SCS, wherein the at least one second reference SCS corresponds to the same service cell.

[0100] The first object may include but is not limited to at least one of an uplink subband, a downlink subband, and a guard band. The information of the first object includes at least one of the bandwidth of the first object (such as bandwidth size, bandwidth position, etc.), the starting PRB, the ending PRB, and the number of PRBs.

[0101] Exemplarily, for a service cell, the network side device may configure one or more second reference SCSs, and configure an uplink subband list (UL subband list), a downlink subband list (DL subband list) (or a guard band list). The uplink subband list contains one or more uplink subband configurations under the second reference SCS, the downlink subband list contains one or more downlink subband configurations under the second reference SCS, and the guard band list contains one or more guard band configurations under the second reference SCS. For example, the base station is respectively configured with at least one of the bandwidth (such as bandwidth size, bandwidth position, etc.), starting PRB, ending PRB, and the number of PRBs corresponding to the uplink subband or downlink subband or guard band under SCS of 15kHz, 30kHz, and 60kHz.

[0102] In some embodiments, the second reference SCS corresponding to the uplink subband and the second reference SCS corresponding to the downlink subband (or guard band) may be the same or different. For example, the base station configures the second reference SCS corresponding to the uplink subband and the second reference SCS corresponding to the downlink subband (or guard band) respectively.

[0103] 303) Information of the first object corresponding to the third reference SCS, where the third reference SCS is the reference SCS corresponding to the TDD-UL-DL-Pattern.

[0104] The first object may include but is not limited to at least one of an uplink subband, a downlink subband, and a guard band. The information of the first object includes at least one of the bandwidth of the first object (such as bandwidth size, bandwidth position, etc.), the starting PRB, the ending PRB, and the number of PRBs.

[0105] In one implementation, for the case where the terminal is configured with an uplink BWP and a downlink BWP, the terminal does not expect that some RBs are included in the intersection of the uplink BWP and the configured uplink subband (i.e., according to the SCS of the UL BWP, the number of subcarriers in the intersection is not an integer multiple of 12), or the terminal does not expect that some RBs are included in the intersection of the downlink BWP and the configured downlink subband (i.e., according to the SCS of the DL BWP, the number of subcarriers in the intersection is not an integer multiple of 12).

[0106] 304) Information of a first object corresponding to a fourth SCS, wherein the information of the first object is configured at a granularity of a BWP pair, and the fourth SCS is associated with the SCS corresponding to the BWP pair. The BWP pair may include an uplink BWP and a downlink BWP.

[0107] In this embodiment, the fourth SCS is related to the SCS corresponding to the BWP pair, and may include but is not limited to: if the first object includes an uplink subband, the fourth SCS corresponding to the uplink subband is the same as the SCS corresponding to the uplink BWP; if the first object includes a downlink subband or a guard band, the fourth SCS corresponding to the downlink subband or guard band is the same as the SCS corresponding to the downlink BWP. Therefore, the corresponding subband configuration is configured for each BWP pair respectively, and there is no need to determine the SBFD subband based on the reference SCS, which reduces the complexity of the SBFD subband configuration and determination.

[0108] It is worth noting that, with respect to the several frequency domain resource configuration methods provided in 301)-304), the frequency domain resources may be configured for the terminal using only one of the aforementioned methods, or may be configured for the terminal using several of the aforementioned methods simultaneously. For the latter method, the actual frequency domain resource configuration method used for communication transmission under SBFD may be determined by protocol agreement, network configuration, or terminal implementation.

[0109] In addition, for the frequency domain resource configuration information provided in 301)-303) above, if the terminal is configured with a BWP, then for each uplink BWP or downlink BWP, the terminal can determine the configuration of the corresponding uplink subband or downlink subband based on the reference SCS of the corresponding BWP, that is, the corresponding uplink subband and downlink subband with the same reference SCS.

[0110] For example, assuming that the reference SCS is 60kHz, then if for a certain subband configuration, the corresponding starting PRB index is 10 and the number of PRBs is 20, then for a BWP with an SCS of 15kHz, the corresponding subband configuration has a starting PRB index of 40 and a number of PRBs of 80.

[0111] S220: The terminal performs communication transmission according to the resource configuration information.

[0112] Among them, there are multiple ways for the terminal to perform communication transmission according to the resource configuration information. For example, for a time domain unit configured as SBFD, available resources can be determined based on the intersection between the currently activated BWP and the SBFD subband, and then communication transmission is performed based on the available resources. This embodiment does not impose any restrictions here.

[0113] In this embodiment, a resource configuration solution under SBFD is provided to implement communication transmission under SBFD and ensure the effectiveness of the communication system.

[0114] Based on the description of the aforementioned method embodiment 200, for ease of understanding, the communication method provided in this embodiment is further exemplified in combination with Example 1 and Example 2, as follows.

[0115] Example 1

[0116] Assume that a network-side device (such as a base station) configures a cell-specific uplink / downlink TDD configuration (Uplink / Downlink TDD configuration) via signaling TDD-UL-DL-ConfigCommon. One or two TDD-UL-DL patterns may be configured in the TDD-UL-DL-ConfigCommon, and each TDD-UL-DL pattern may be configured with a DL slot, a flexible slot, or a UL slot.

[0117] Then, for the time domain resource configuration information corresponding to SBFD, the network side device can configure the SBFD time slot or symbol in each TDD-UL-DL-Pattern through the following configuration methods 1 to 3.

[0118] Configuration method 1: The network-side device configures the following information 401)-403) in each TDD-UL-DL-Pattern through high-layer signaling, such as cell-specific signaling.

[0119] 401) The index of the starting time slot corresponding to the SBFD time domain resource, the index of the starting symbol in the starting time slot, or the number of time slots and the number of symbols corresponding to the non-SBFD time domain resource.

[0120] 402) The number of consecutive time slots or the index of the end time slot corresponding to the SBFD time domain resource.

[0121] 403) The number of end symbols corresponding to the SBFD time domain resource, or the index of the end symbol in the end slot corresponding to the SBFD time domain resource.

[0122] Based on this, in one implementation, assuming that the time domain resource configuration information in each of the TDD-UL-DL-Pattern can be configured through SBFDConfig, then one or more SBFDConfigs can be included through an SBFDConfigList, that is, an SBFDConfigList can be used to configure the SBFD time slots or symbols in one or more TDD-UL-DL-Pattern.

[0123] SBFDConfigList::=SEQUENCE(SIZE(1..maxNrofSBFD-pattern))OF SBFDConfig

[0124] Wherein, maxNrofSBFD-pattern may be an integer equal to or greater than 2. In addition, SBFDConfig may include the following.

[0125] Here, startingSlotIndex represents the index of the starting time slot corresponding to the SBFD time domain resource in a TDD-UL-DL pattern.

[0126] nrofSBFDSymbols1 or startingSymbolIndex is used to configure the position of the starting symbol within the starting timeslot corresponding to the SBFD time domain resource. nrofSBFDSymbols indicates the number of symbols used for SBFD transmission within the starting timeslot, and startingSymbolIndex indicates the index of the starting symbol for SBFD within the starting timeslot. The nrofSBFDSymbols1 or startingSymbolIndex parameter can be left unconfigured. If not configured, the default starting symbol is a predefined symbol in the starting timeslot, such as the first symbol.

[0127] nrofSBFDSymbols1 represents the number (e.g., n) of symbols configured as SBFD (also referred to as SBFD symbols) in the starting time slot corresponding to the SBFD time domain resource. When determining the number of SBFD symbols, n symbols may be counted from the last symbol in the starting time slot toward the first symbol. Optionally, the parameter nrofSBFDSymbols1 may not be configured. If not configured, the number of SBFD symbols may be calculated by default starting from a predefined symbol (e.g., the first symbol) in the starting time slot.

[0128] nrofSBFDSlots or endingSlotIndex is used to configure the number of consecutive time slots corresponding to the SBFD time domain resource. In one embodiment, as shown in FIG3 , the number of consecutive time slots may not include the starting time slot and the ending time slot, or may include the starting time slot and the ending time slot, without limitation.

[0129] nrofSBFDSymbols2 or endingSymbolIndex is used to configure the position of the ending symbol within the ending slot corresponding to the SBFD time domain resource. nrofSBFDSymbols2 can represent the index of the ending symbol within the ending slot. Optionally, this parameter nrofSBFDSymbols2 can be left unconfigured. If not configured, the ending symbol defaults to a predefined symbol within the ending slot, such as the last symbol.

[0130] Alternatively, nrofSBFDSymbols2 may also represent the number of SBFD symbols (e.g., m) in the end slot corresponding to the SBFD time-domain resource. When determining the number of SBFD symbols, m symbols may be counted from the first symbol in the end slot toward the last symbol. Optionally, the parameter nrofSBFDSymbols2 may not be configured. If not configured, a predefined symbol (e.g., the first symbol) in the end slot may be assumed to be the end symbol.

[0131] Configuration method 2

[0132] The network side device may configure the time domain resource configuration information to include first indication information, such as SLIV of the Symbol level, through high-layer signaling. When S in SLIV is 0, the starting symbol corresponding to the SBFD time domain resource may be determined to be the first symbol in the TDD-UL-DL-Pattern.

[0133] For example, assuming that the time domain resource configuration information in each TDD-UL-DL-Pattern can be configured through SBFDConfig, such as being used to configure SBFD time slots or symbols in one or more TDD-UL-DL-Pattern, then SBFDConfig can be as follows.

[0134] Configuration method 3

[0135] The network side device configures the time domain resource configuration information in each TDD-UL-DL-Pattern through high-layer signaling, such as cell-specific signaling, wherein the time domain resource configuration information may include the various information described in the following 501)-502).

[0136] 401) Index of the starting time slot corresponding to the SBFD time domain resource.

[0137] 402) Symbol level SLIV, or, the index of the starting symbol and the number of consecutive symbols within the starting time slot.

[0138] For example, assuming that the time domain resource configuration information in each TDD-UL-DL-Pattern can be configured via SBFDConfig, such as being used to configure SBFD time slots or symbols in one or more TDD-UL-DL-Pattern, then SBFDConfig can be configured as shown in configuration method 2.

[0139] The relevant descriptions of each configuration method in this example 1 can refer to the description in the aforementioned method embodiment 200 and will not be repeated here.

[0140] Example 2

[0141] When the network side device (such as a base station) configures the frequency domain resource configuration information corresponding to SBFD, its configuration method may include at least one of the following configuration methods 1 to 4, so that the terminal can perform uplink transmission on the uplink subband and downlink reception on the downlink subband.

[0142] Configuration method 1

[0143] The base station configures the first reference SCS of the uplink subband and downlink subband (or protection band), as well as the information of the uplink subband and downlink subband (or protection band) under the first reference SCS, such as bandwidth size and position, starting PRB, number of PRBs, etc.

[0144] Optionally, the terminal expects that the first reference SCS corresponding to the uplink subband is greater than or equal to the SCS of any uplink BWP configured with the terminal, and the terminal expects that the first reference SCS corresponding to the downlink subband (or protection band) is greater than or equal to the SCS of any downlink BWP configured with the terminal.

[0145] Based on this, for each DL / UL BWP, the terminal can determine the configuration of the uplink subband and downlink subband according to the corresponding reference SCS. If the reference SCS corresponding to the DL / UL BWP and the uplink subband / downlink subband is different, a corresponding conversion is performed.

[0146] For example, for the case where the reference SCS corresponding to the DL / UL BWP and the uplink subband / downlink subband is different, assuming that the reference SCS is 60kHz, then if for a certain subband configuration, the corresponding starting PRB index is 10 and the number of PRBs is 20, then for the BWP with an SCS of 15kHz, the corresponding subband configuration has a starting PRB index of 40 and a PRB number of 80.

[0147] Configuration method 2

[0148] The base station configures uplink subbands and downlink subbands under one or more second reference SCSs on a serving cell. For example, the base station may configure an uplink subband list, which includes configurations of uplink subbands corresponding to one or more second reference SCSs, and the base station may configure a downlink subband list (or guard band list), which includes configurations of one or more downlink subbands.

[0149] Based on this, for each DL / UL BWP, the terminal can determine the uplink subband and downlink subband configuration based on the corresponding reference SCS. If the DL / UL BWP and the reference SCS corresponding to the uplink subband / downlink subband are different, corresponding conversion is performed.

[0150] Configuration method 3

[0151] The base station configures the uplink subband and downlink subband (or protection band) information, such as bandwidth size and position, starting PRB, etc., according to the third reference SCS in the TDD UL-DL pattern configured for the terminal.

[0152] Optionally, the terminal does not expect that the intersection of a certain BWP and a UL / downlink subband includes some RBs (ie, the number of subcarriers is not an integer multiple of 12).

[0153] Based on this, for each DL / UL BWP, the terminal can determine the uplink subband and downlink subband configuration based on the corresponding reference SCS. If the DL / UL BWP and the reference SCS corresponding to the uplink subband / downlink subband are different, corresponding conversion is performed.

[0154] Configuration method 4

[0155] The base station can configure the uplink subband and downlink subband (or guard band) information for the terminal at the granularity of a single (per) BWP pair, such as bandwidth size and position, starting PRB, etc. The fourth reference SCS corresponding to the uplink subband is the same as the SCS corresponding to the uplink BWP, and the fourth reference SCS of the downlink subband (or guard band) is the same as the SCS corresponding to the downlink BWP.

[0156] The relevant descriptions of each configuration method in this example 2 can refer to the description in the aforementioned method embodiment 200 and will not be repeated here.

[0157] FIG4 is a flow chart of a communication method 400 according to an exemplary embodiment of the present application. This method 400 may be, but is not limited to, executed by a terminal, specifically by at least one of hardware and software installed in the terminal. In this embodiment, the method 400 may include at least the following steps.

[0158] S410: The terminal obtains resource configuration information from a network-side device.

[0159] The resource configuration information includes at least one of time domain resource configuration information and frequency domain resource configuration information corresponding to SBFD.

[0160] S420: The terminal performs communication transmission according to the resource configuration information.

[0161] It can be understood that the implementation process of S410-S420 can refer to the relevant description in the aforementioned method embodiment 200. Of course, in this embodiment, in addition to referring to the relevant description in the aforementioned method embodiment 200, please refer to Figure 4 again. The process of the terminal described in S420 performing communication transmission according to the resource configuration may include S421-S422 shown in Figure 4, the content is as follows.

[0162] S421 : Determine a target time domain unit configured as an SBFD time domain resource according to the time domain resource configuration information, and determine an SBFD subband according to the frequency domain resource configuration information.

[0163] The target time domain unit may be, but is not limited to, a time slot, a symbol, etc. It is understandable that, in this embodiment, for time domain units configured as SBFD, different time domain units correspond to the same frequency domain resource configuration.

[0164] The SBFD subband includes at least one of a downlink subband and an uplink subband. In this embodiment, the downlink subband can be determined by the downlink subband configuration information in the frequency domain resource configuration information, or by the uplink subband configuration information and the guard band configuration information in the frequency domain resource configuration information; similarly, the uplink subband can be determined by the uplink subband configuration information in the frequency domain resource configuration information, or by the downlink subband configuration information and the guard band configuration information in the frequency domain resource configuration information, without limitation herein.

[0165] S422: Perform communication transmission on the target time domain unit according to the intersection information between the SBFD subband and the activated BWP.

[0166] The activation of the BWP is implemented based on a network-side indication or a preconfigured timer for BWP activation. In this embodiment, the activation of the BWP may include at least one of a downlink activation BWP (or simply a downlink BWP) and an uplink activation BWP (or simply an uplink BWP).

[0167] In this embodiment, considering that the frequency domain resource configuration information corresponding to the SBFD corresponds to a specific cell (cell-specific), and the BWP configuration corresponds to a specific UE (UE-specific), therefore, for the case where the terminal is configured with both the frequency domain resource configuration information and the BWP configuration corresponding to the SBFD, the terminal can implement communication transmission on the target time domain unit based on the intersection information between the SBFD subband and the activated BWP to ensure communication effectiveness. The intersection information can be understood as whether the intersection between the SBFD subband and the activated BWP is an empty set, such as whether the intersection between the uplink activated BWP and the downlink subband is an empty set, whether the intersection between the downlink activated BWP and the downlink subband is an empty set, etc.

[0168] In this case, the terminal may perform communication transmission on the target time domain unit in multiple ways according to whether the intersection between the SBFD subband and the activated BWP is an empty set. The following describes each of these ways in combination with different implementations.

[0169] The first implementation method

[0170] Assuming that the intersection between the downlink activated BWP and the downlink subband is an empty set as shown in Figure 5a, then the terminal can execute at least one of the following methods 11 to 13, thereby enabling the terminal to clearly understand how to perform communication transmission when there is no overlap between the downlink activated BWP and the downlink subband, thereby achieving reliable communication transmission.

[0171] Mode 11: The terminal determines the intersection between the uplink activated BWP and the uplink subband as an uplink available resource, and performs a first uplink transmission on the target time domain unit based on the uplink available resource, wherein the intersection between the uplink activated BWP and the uplink subband is a non-empty set.

[0172] In an optional implementation, when the terminal performs a first uplink transmission on the target time domain unit configured as the SBFD based on the uplink available resources, the terminal may perform the first uplink transmission on the target time domain unit according to the first transmission parameter and the uplink available resources. The first transmission parameter may be a transmission parameter corresponding to the SBFD time domain type, such as at least one of the pre-configured uplink available resources corresponding to the SBFD, beam-related parameters, power control parameters, physical uplink control channel (PUCCH) resource configuration, configured grant physical uplink shared channel (PUSCH), etc. The beam-related parameters may include but are not limited to quasi co-location (QCL) information, spatial relation information, etc.

[0173] Alternatively, the first transmission parameter may be a transmission parameter corresponding to a second uplink transmission whose transmission time is closest to the first uplink transmission, that is, the terminal may perform the first uplink transmission on the target time domain unit based on a transmission parameter that is the same as or related to the transmission parameter used for the second uplink transmission.

[0174] The second uplink transmission may include but is not limited to a physical random access channel (PRACH), a PUCCH, a PUSCH, etc. Transmission parameters corresponding to the second uplink transmission may include but are not limited to available frequency domain resources, beam-related parameters, power control parameters, etc.

[0175] In this embodiment, the priority of the second uplink transmission may be the same as the priority of the first uplink transmission. This allows the transmission parameters of the second uplink transmission to better match the transmission parameters of the first uplink transmission, while also ensuring the transmission validity of high-priority channels or avoiding waste of transmission power. For example, the physical layer priority index of the second uplink transmission may be the same as the physical layer priority index of the first uplink transmission.

[0176] Mode 12: performing communication transmission on the target time domain unit based on the transmission parameters corresponding to the non-SBFD time domain type.

[0177] Among them, the transmission parameters corresponding to the non-SBFD time domain type can be understood as: the transmission parameters configured by the network side device and used when performing up / down transmission on the non-SBFD time domain unit, such as frequency domain available resources, beam-related parameters, power control parameters, PUCCH resource configuration, configured grant (configured grant PUSCH), etc. At least one item; similarly, the transmission parameters corresponding to the SBFD time domain type mentioned later can be understood as the transmission parameters configured by the network side device and used when performing up / down transmission on the SBFD time domain unit.

[0178] In addition, when the terminal performs communication transmission on the target time domain unit based on the transmission parameters corresponding to the non-SBFD time domain type, it can perform communication transmission in the downlink activated BWP or uplink activated BWP according to the TDD-UL-DL-PATTERN configuration, such as downlink reception or uplink transmission.

[0179] For example, if at least one of Tdd-UL-DL-ConfigurationCommon and Tdd-UL-DL-ConfigurationDedicated is configured as a DL symbol, then within the DL symbol, the terminal can only perform downlink reception within the DL activated BWP.

[0180] For another example, if at least one of tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated is configured as a flexible symbol, or is indicated as a flexible symbol by a slot format indicator (SFI), the terminal can perform communication transmission within a DL-activated BWP or a UL-activated BWP according to the base station configuration or scheduling.

[0181] Mode 13: performing communication transmission on the target time domain unit according to the first transmission mode configured, scheduled or indicated by the network side device on the target time domain unit.

[0182] Optionally, the first transmission mode may be configured, scheduled or indicated through, but not limited to, dedicated signaling.

[0183] In this embodiment, for the situation where the terminal performs communication transmission on the target time domain unit according to the first transmission mode scheduled by the network side device on the target time domain unit, if the first transmission mode scheduled by the network side device on the target time domain unit is downlink reception, the terminal can perform the downlink reception on the target time domain unit according to the transmission parameters corresponding to the non-SBFD time domain type.

[0184] Alternatively, if the first transmission mode scheduled by the network side device on the target time domain unit is uplink transmission within the uplink activation BWP, the uplink transmission is performed on the target time domain unit according to the second transmission parameter, wherein the second transmission parameter is the transmission parameter indicated by the network side device when scheduling the first transmission mode, or the second transmission parameter is a transmission parameter agreed upon by the protocol.

[0185] It is worth noting that, in addition to the aforementioned method, the first transmission method may also be the aforementioned method 11 or method 22, etc.

[0186] The second implementation method

[0187] Assuming that the intersection between the uplink activated BWP and the uplink subband is an empty set as shown in Figure 5b, then the terminal can execute at least one of the following methods 21 to 23, thereby enabling the terminal to clearly understand how to perform communication transmission when there is no overlap between the downlink activated BWP and the downlink subband.

[0188] Method 21: Determine the intersection between the downlink activated BWP and the downlink subband as the downlink available resources, and perform a first downlink reception on the target time domain unit based on the downlink available resources, wherein the intersection between the downlink activated BWP and the downlink subband is a non-empty set.

[0189] In an optional implementation, when the terminal performs the first downlink reception on the target time domain unit based on the downlink available resources, the terminal may perform the first downlink reception on the target time domain unit according to the third transmission parameter and the downlink available resources. The third transmission parameter may be a transmission parameter corresponding to the SBFD time domain type, such as the pre-configured downlink available resources corresponding to SBFD, beam-related parameters, power control parameters, control resource set (CORESET), search space, physical downlink control channel (PDCCH) configuration, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) configuration, channel state information reference signal (CSI-RS) configuration, etc. At least one item, the beam-related parameters may include but are not limited to QCL information, spatial relation information, etc.

[0190] Alternatively, the third transmission parameter is the transmission parameter corresponding to the second downlink reception whose transmission time is closest to the first downlink reception, that is, the terminal can perform the first downlink reception on the target time domain unit based on the transmission parameter that is the same as or related to the transmission parameter used by the second downlink reception.

[0191] The second downlink reception may include but is not limited to a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), etc. Transmission parameters corresponding to the second downlink reception may include but are not limited to at least one of frequency domain available resources, beam-related parameters, power control parameters, CORESET, search space, PDCCH configuration, SPS configuration, and CSI-RS configuration.

[0192] In an optional implementation, the priority of the second downlink reception is the same as the priority of the first downlink reception. For example, the physical layer priority index of the second downlink reception is the same as the physical layer priority index of the first downlink reception, or the physical layer priority index corresponding to the HARQ-ACK feedback corresponding to the second downlink reception is the same as the physical layer priority index corresponding to the HARQ-ACK feedback corresponding to the first downlink reception.

[0193] Mode 22: performing communication transmission on the target time domain unit based on the transmission parameters corresponding to the non-SBFD time domain type.

[0194] Among them, when the terminal performs communication transmission on the target time domain unit based on the transmission parameters corresponding to the non-SBFD time domain type, it can perform communication transmission in the downlink activated BWP or uplink activated BWP according to the TDD-UL-DL-PATTERN configuration, such as downlink reception or uplink transmission.

[0195] For example, if at least one of Tdd-UL-DL-ConfigurationCommon and Tdd-UL-DL-ConfigurationDedicated is configured as a DL symbol, downlink reception can only be performed within the DL activated BWP within the DL symbol.

[0196] For another example, if at least one of tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated is configured as a Flexible symbol, or is indicated as a Flexible symbol by SFI, the terminal can perform communication transmission within the DL activated BWP or UL activated BWP according to the base station configuration or scheduling.

[0197] Mode 23: performing communication transmission on the target time domain unit according to the second transmission mode configured, scheduled or indicated by the network side device on the target time domain unit.

[0198] Optionally, the second transmission mode may be configured, scheduled or indicated through, but not limited to, dedicated signaling.

[0199] In this embodiment, for the situation where the terminal performs communication transmission on the target time domain unit according to the second transmission mode scheduled by the network side device on the target time domain unit, if the second transmission mode scheduled by the network side device on the target time domain unit is uplink transmission, the terminal can perform the uplink transmission on the target time domain unit according to the transmission parameters corresponding to the non-SBFD time domain type.

[0200] Alternatively, if the second transmission mode scheduled by the network side device on the target time domain unit is downlink reception, the downlink reception is performed on the target time domain unit according to a fourth transmission parameter, wherein the fourth transmission parameter is the transmission parameter indicated by the network side device when scheduling the second transmission mode, or the second transmission parameter is a transmission parameter agreed upon by the protocol.

[0201] It is worth noting that, in addition to the aforementioned method, the second transmission method may also be the aforementioned method 21 or method 22, etc.

[0202] The third implementation method

[0203] Assuming that the intersection between the SBFD subband and the activated BWP is a non-empty set, the process of the terminal performing communication transmission on the target time domain unit may include at least one of Modes 31 to 34, thereby ensuring smooth communication transmission.

[0204] In mode 31, the terminal may determine the intersection of the uplink activated BWP and the uplink subband as an uplink available resource, and perform communication transmission, such as uplink transmission, on the target time domain unit based on the uplink available resource.

[0205] Mode 32: Determine the intersection of the downlink activated BWP and the downlink subband as the downlink available resource, and perform communication transmission on the target time domain unit based on the downlink available resource, such as downlink reception.

[0206] Mode 33: At the target time unit, the terminal does not expect the intersection of the downlink activation BWP and the downlink subband to be an empty set, that is, the terminal expects the intersection between the downlink activation BWP and the downlink subband configured or indicated by the network side device to be a non-empty set.

[0207] Mode 34: At the target time unit, the terminal does not expect the intersection of the uplink activated BWP and the uplink subband to be an empty set, that is, the terminal expects the intersection between the uplink activated BWP and the uplink subband configured or indicated by the network side device to be a non-empty set.

[0208] The fourth implementation method

[0209] Assuming that the intersection between the downlink activated BWP and the downlink subband is an empty set, and the intersection between the uplink activated BWP and the uplink subband is an empty set, then the terminal can perform communication transmission on the target time domain unit according to the transmission parameters corresponding to the non-SBFD time domain type.

[0210] This embodiment provides a communication transmission method under SBFD, which enables a terminal to perform communication transmission on the target time domain unit according to the intersection information between the SBFD subband and the activated BWP, thereby improving the effectiveness of the communication system.

[0211] Based on the description of the above method embodiments 200 and 400, for ease of understanding, the communication method provided in this embodiment is further illustrated below in combination with Example 3. The content is as follows.

[0212] Example 3

[0213] It is assumed that the network side device (such as a base station) can configure the time domain resource configuration information and frequency domain resource configuration information corresponding to SBFD for the terminal through cell specific signaling, such as system information block (SIB) or cell common signaling, such as SBFD symbol, uplink subband, downlink subband and protection band. At least one of the cell common signaling can be but is not limited to BWP-UplinkCommon signaling or BWP-DowninkCommon signaling.

[0214] Assume that the base station configures two sets of transmission parameters for the terminal, such as the transmission parameters corresponding to the SBFD time domain type for transmission on SBFD symbols and the transmission parameters corresponding to the non-SBFD time domain type for transmission on non-SBFD symbols. The transmission parameters may include transmission parameters corresponding to PDCCH-configuration (config), PDSCH-config, PUCCH-config, PUSCH-config, Sounding Reference Signal (SRS) CSI-RS, etc.

[0215] The terminal is configured with two downlink BWPs, such as downlink BWP 1 and downlink BWP 2, and two uplink BWPs, such as uplink BWP 1 and uplink BWP2, wherein downlink BWP 1 and uplink BWP 1 are a BWP pair, and downlink BWP 2 and uplink BWP 2 are a BWP pair (uplink and downlink BWP pairs are activated or deactivated at the same time).

[0216] Then, as shown in Figure 5c, if the downlink BWP1 and the downlink sub-band have an intersection, the uplink BWP1 and the uplink sub-band have no intersection, and the activated BWP is downlink BWP1 and uplink BWP1, for a symbol configured as SBFD (i.e., the target time domain unit), the terminal can perform any one of the following operations 1-3.

[0217] Operation 1: Determine the intersection between the downlink BWP1 and the downlink subband as a downlink available resource, and perform a first downlink reception on the symbol configured as SBFD based on the downlink available resource.

[0218] Operation 2: Transmit according to non-SBFD symbols, such as performing communication transmission on the symbols configured as SBFD based on transmission parameters corresponding to the non-SBFD time domain type.

[0219] Operation 3: performing communication transmission on the target time domain unit according to the transmission mode configured, scheduled, or indicated by the network-side device on the symbol configured as SBFD.

[0220] In another implementation, referring again to Figure 5c , when the terminal's active BWP switches from downlink / uplink BWP1 to downlink / uplink BWP2, downlink BWP2 has no intersection with the downlink subband, while uplink BWP2 has an intersection with the uplink subband. Therefore, for a symbol configured as SBFD (i.e., the target time-domain unit), the terminal may perform at least one of the following operations 1-3.
