[0148] As shown in Figure 1, a communication processing method provided in an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and may be connected to multiple component carriers of the network device 102, including a primary component carrier and one or more secondary component carriers.

[0149] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0150] The user equipment 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a terminal device, etc. The user equipment 101 may have wireless transceiver functions, and may be capable of communicating (e.g., wireless communication) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0151] Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

[0152] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0153] For example, the network device 102 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home node B, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.

[0154] The present disclosure provides a communication processing method. Referring to FIG2 , FIG2 shows a communication processing method according to an exemplary embodiment. As shown in FIG2 , the method includes steps S2101 to S2102. Specifically:

[0155] In step S2101 , the network device 102 sends a first signaling to the user equipment 101 , where the first signaling includes configuration information of a precoding resource block group (PRG) applicable to a sub-band full-duplex (SBFD) time domain unit.

[0156] In some possible implementations, the first signaling may be Radio Resource Control (RRC) signaling and / or DCI signaling. For example, the network device 102 sends PRG configuration information applicable to the SBFD time domain unit by sending RRC signaling.

[0157] In some possible implementations, an SBFD time-domain unit may be an SBFD symbol or an SBFD slot. For example, when the frequency domain range corresponding to a symbol includes both a DL subband and a UL subband, the symbol may be considered an SBFD symbol. If a slot's multiple symbols include at least one SBFD symbol, the slot may be considered an SBFD slot. Alternatively, if all of a slot's multiple symbols are SBFD symbols, the slot may be considered an SBFD slot.

[0158] In one example, Figure 3 illustrates a schematic diagram of an SBFD time-domain unit, where the horizontal axis represents time and the vertical axis represents frequency. As shown in Figure 3 , taking the time-domain unit as a time slot, time slot #0 is a DL time slot, time slots #1-3 are SBFD time slots, and time slot #4 is a UL time slot.

[0159] In some possible implementations, in an SBFD time domain unit, such as the SBFD time slot shown in FIG3 , the SBFD time domain unit includes a frequency domain range used for DL ​​transmission, such as the DL subband in FIG3 ; the SBFD time domain unit also includes a frequency domain range that cannot be used for DL ​​transmission (referred to as the third frequency domain range in the following embodiments).

[0160] In some possible implementations, the first signaling may further indicate the third frequency domain range.

[0161] In one example, the third frequency domain range includes at least one of the following:

[0162] Frequency domain range used for uplink UL transmission;

[0163] The frequency domain range corresponding to the guard band (GB).

[0164] The frequency domain range used for UL transmission is the UL subband in Figure 3. A GB can be set between the UL subband and the DL subband to reduce mutual interference between DL signals in the DL subband and UL signals in the UL subband through frequency isolation. In this example, the frequency domain range corresponding to the UL subband and the GB cannot be used for DL ​​transmission.

[0165] In some possible implementations, in an SBFD time-domain unit, a frequency domain portion excluding the third frequency domain range, such as a frequency domain portion excluding a GB or UL subband, may be used for DL ​​transmission. For example, the frequency domain portion of the SBFD time-domain unit used for DL ​​transmission includes a first frequency domain range and a second frequency domain range. However, due to the presence of the third frequency domain range, the first frequency domain range and the second frequency domain range used for DL ​​transmission may be discontinuous.

[0166] In some possible implementations, before sending the first signaling, the network device 102 may send the time domain resource configuration corresponding to the SBFD time domain unit. Alternatively, the network device 102 may simultaneously send the time domain resource configuration of the SBFD time domain unit and the PRG configuration information in the first signaling.

[0167] In one example, the network device 102 may perform time division duplex (TDD) configuration through RRC signaling to indicate time domain allocation of DL transmission and UL transmission to the user equipment 101. For example, the network device 102 may use TDD-UL-DL-ConfigCommon information to configure a cell-specific time domain unit for UL transmission and a time domain unit for DL ​​transmission, or use TDD-UL-DL-ConfigDedicated information to configure a user equipment-specific time domain unit for UL transmission and a time domain unit for DL ​​transmission, or use DCI2-0 of downlink control information (DCI) to indicate a symbol as a DL symbol or an F symbol.

[0168] In some possible implementations, the PRG configuration information may apply only to SBFD time domain units, or only to non-SBFD DL time domain units (hereinafter referred to as DL time domain units), or apply to both SBFD time domain units and DL time domain units. A DL time domain unit may be a DL symbol or a DL time slot as shown in FIG3 .

[0169] It is worth noting that the DL time domain unit refers to a time domain unit used only for DL ​​transmission, while the SBFD time domain unit includes a DL subband for DL ​​transmission and a UL subband for UL transmission.

[0170] In some possible implementations, the PRG configuration information may include relevant information of the PRG configured by the network device 102, such as the configuration value or type of the PRG size, which may be described in detail in the following embodiments.

[0171] As can be understood, precoding is used to improve transmission performance during Physical Downlink Shared Channel (PDSCH) transmission. A PRG may represent the granularity of configuring precoding, and user equipment 101 may assume that the same precoding matrix is ​​used across a set of consecutive Physical Resource Blocks (PRBs) represented by the PRG.

[0172] In some possible implementations, the user equipment 101 receives first signaling sent by the network device 102 .

[0173] Step S2102: The user equipment 101 determines a first PRG size for downlink (DL) transmission in an SBFD time domain unit according to the first signaling.

[0174] In some possible implementations, the user equipment 101 determines a first PRG size (PRG size) for DL ​​transmission according to PRG configuration information applicable to the SBFD time domain unit in the first signaling.

[0175] In some possible implementations, the first PRG size may be one of {wideband, n2, n4}, as described in the following embodiments.

[0176] In one example, when the first PRG size is a wideband PRG, it indicates that the user equipment 101 does not expect all DL PRBs scheduled by the network device 102 to be discontinuous, that is, the user equipment 101 expects all DL PRBs scheduled by the network device 102 to be continuous.

[0177] In one example, when the size of the first PRG is n2 or is recorded as 2, it means that the PRG includes 2 consecutive PRBs, and the transmission of the 2 consecutive PRBs can use the same precoding matrix.

[0178] In one example, when the size of the first PRG is n4 or is recorded as 4, it means that the PRG includes 4 consecutive PRBs, and the transmission of the 4 consecutive PRBs can use the same precoding matrix.

[0179] In some possible implementations, when the first signaling also includes a third frequency domain range that is not available for DL ​​transmission, the user equipment 101 may also determine the first frequency domain range and the second frequency domain range in the SBFD time domain unit based on the third frequency domain range, wherein the first frequency domain range and the second frequency domain range may be discontinuous.

[0180] It is understandable that the relevant protocol only defines the configuration and determination method of the second PRG size of the DL time domain unit. Since the SBFD time domain unit also includes the UL subband for UL transmission, there are different ways to determine the first PRG size and the second PRG size in the SBFD time domain unit.

[0181] The “first” and “second” in the first PRG size and the second PRG size are only used to distinguish the PRG size of the SBFD time domain unit from the PRG size of the DL time domain unit, and do not impose additional restrictions on the meaning or order of the PRG size.

[0182] In the disclosed embodiment, the network device 102 configures PRG configuration information applicable to the SBFD time domain unit through first signaling, thereby providing a reference configuration for determining the size of the first PRG in the SBFD scenario. The user equipment 101 can thereby more accurately determine the first PRG size of the SBFD time domain unit based on the PRG configuration information, thereby improving data transmission accuracy during the SBFD time domain unit transmission process.

[0183] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4a, FIG4a shows a communication processing method according to an exemplary embodiment. As shown in FIG4a, the method includes steps S4101 to S4102, specifically:

[0184] Step S4101: User equipment 101 receives first signaling sent by network equipment 102, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0185] In some possible implementations, the implementation of step S4101 can refer to the relevant implementation of step S2101 and will not be repeated here.

[0186] In some possible implementations, the SBFD time-domain unit may be an SBFD symbol or an SBFD time slot. For example, when the frequency domain range corresponding to a symbol includes both a DL subband and a UL subband, the symbol may be considered an SBFD symbol. If a time slot includes at least one SBFD symbol among multiple symbols, the time slot may be considered an SBFD time slot. For example, as shown in Figure 3, time slots 1-3 are SBFD time slots. Alternatively, if all symbols in a time slot are SBFD symbols, the time slot may be considered an SBFD time slot.

[0187] In some possible implementations, the PRG configuration information is dedicated to the SBFD time domain unit, that is, the network device 102 specifically configures the PRG configuration information applicable to the SBFD time domain unit scenario for the user equipment 101. In this case, the network device 102 configures two sets of PRG configuration information, one set applicable to the SBFD time domain unit and the other set applicable to the DL time domain unit.

[0188] In some possible implementations, the PRG configuration information is applicable to both SBFD time domain units and non-SBFD DL time domain units. In this case, the network device 102 is configured with only one set of PRG configuration information, which is shared by both SBFD time domain units and DL time domain units.

[0189] In some possible implementations, the PRG configuration information may include PRG related information.

[0190] In one example, when configuring PRG related information through the first signaling, the network device 102 may indicate the PRG binding type of the PRG through a first field in the first signaling, where the first field is, for example, prb-BundlingType or prb-BundlingType_SBFD.

[0191] In this example, the PRG binding type includes a static type (static) or a dynamic type (dynamic).

[0192] In an example, the network device 102 may indicate the first bundling size setting through a second field in the first signaling, where the second field is, for example, bundleSizeSet1 or bundleSizeSet1_SBFD.

[0193] In this example, the first binding size setting can be configured as 1 or 2 of {2, 4, wideband}.

[0194] In an example, the network device 102 may indicate the second bundling size setting through a third field in the first signaling, where the third field is, for example, bundleSizeSet2 or bundleSizeSet2_SBFD.

[0195] In this example, the second binding size setting can be configured as 1 of {2, 4, wideband}.

[0196] In some possible implementations, the first signaling further includes information indicating a third frequency domain range that is unavailable for DL ​​transmission. Thus, the user equipment 101 can determine a frequency domain range available for DL ​​transmission based on the third frequency domain range.

[0197] In one example, the third frequency domain range includes at least one of the following:

[0198] Frequency domain range used for uplink UL transmission;

[0199] The frequency domain range corresponding to the guard band GB.

[0200] In some possible implementations, the first signaling may be RRC signaling.

[0201] In some possible implementations, when the PRG binding type is configured as a dynamic type, the network device 102 may further send a second signaling.

[0202] In an example, a PRB bundling size indicator field may be configured or not configured in the second signaling.

[0203] In an example, the second signaling may be downlink control information (DCI) signaling.

[0204] Step S4102: The user equipment 101 determines a first PRG size for downlink (DL) transmission in an SBFD time domain unit according to the first signaling.

[0205] In some possible implementations, when the PRG configuration information is only used for SBFD time domain units, such as when the network device 102 is configured with two sets of PRG configuration information, the user equipment 101 may determine the first PRG size based on the relevant information of the PRG. For example, the first PRG size may be determined based on the configuration of at least one of the first field, the second field, and the third field in the first signaling. This approach is described in detail in the embodiment related to FIG. 4 b below.

[0206] In some possible implementations, when the PRG configuration information is applicable to both the SBFD time domain unit and the DL time domain unit, such as when the network device 102 is configured with only one set of PRG configuration information, the user device 101 may determine the first PRG size of the SBFD time domain unit based on the second PRG size of the DL time domain unit. This method may be described in detail in the following description of the relevant embodiments of Figures 4c to 4g.

[0207] In some possible implementations, the method further includes step S4103, specifically:

[0208] Step S4103: The user equipment 101 determines the number of PRBs used for DL ​​transmission in all PRGs within the BWP according to the first PRG size of the SBFD time domain unit.

[0209] In some embodiments, in the SBFD time domain unit, the bandwidth part (BWP) corresponding to the user equipment 101 may include multiple PRGs. The division method of the PRGs in the BWP can be shown in Figure 5, for example, the PRGs are divided according to the determined first PRG size.

[0210] It can be understood that in order to adapt to different types of UE and service types, the 5G spectrum can be divided into different BWPs within a certain time domain range.

[0211] In some embodiments, after determining the first PRG size of each PRG, the total number of PRBs used for DL ​​transmission within the BWP range may be determined.

[0212] In one example, as shown in reference Figure 5, the PRBs in each PRG that overlap with the frequency domain range used for DL ​​transmission (such as the frequency domain range where the DL subband in Figure 5 is located) are the PRBs used for DL ​​transmission in the PRG, and the number of PRBs that can be used for DL ​​transmission in each PRG is determined accordingly.

[0213] In some embodiments, the user equipment 101 may determine the first PRG size of each PRG in the BWP according to possible values ​​of the first PRG size determined by the PRG configuration information and the size of the BWP.

[0214] In some embodiments, if the first PRG size P′ is determined according to the PRG configuration information BWP,i =2 or 4, the size of DL BWP is When the number of PRGs contained in the BWP is N PRG for:

[0215] in, This is the index of the first PRB in the BWP within the Common Resource Block (CRB), i.e., the index of the first PRB in the BWP within the Resource Block (RB) across the entire carrier. As can be appreciated, CRBs can also be used to distinguish the frequency bands occupied by different BWPs. Mod stands for remainder operation.

[0216] In this embodiment, in the BWP, the first PRG size of the first PRG is for:

[0217] exist When the first PRG size of the last PRG in the BWP is for: otherwise,

[0218] Except for the first and last PRG, the first PRG size of other PRGs in the BWP is P′ BWP,i .

[0219] In one example:

[0220] First PRG size P′ BWP,i =4, the PRGs in the BWP include: PRG#0, PRG#1, PRG#2, PRG#3, PRG#4, PRG#5, PRG#6, PRG#7, PRG#8, PRG#9, PRG#10, PRG#11 and PRG#12, as shown in Figure 5.

[0221] In this example, according to It can be determined that the first PRG size of the first PRG is 2, that is, PRG#0 contains 2 PRBs. Based on the calculation method of the first PRG size of the last PRG, it can be determined that the first PRG size of PRG#12 is 3, that is, PRG#12 contains 3 PRBs. The remaining PRGs contain 4 PRBs.

[0222] Based on the overlap of the PRG in the BWP and the frequency domain range for DL ​​transmission, the user equipment 101 can determine the first PRG size of each PRG, that is, the number of PRBs for DL ​​transmission contained in each PRG, wherein the frequency domain range for DL ​​transmission includes the frequency domain range of the DL subband, or the frequency domain range for DL ​​transmission includes the frequency domain range of the DL subband and the frequency domain range of the GB.

[0223] For example, in Figure 5, the frequency domain range used for DL ​​transmission includes the frequency domain range of the DL subband. The PRBs in PRG#0, PRG#1, PRG#2, PRG#3, PRG#9, PRG#10, PRG#11, and PRG#12 are all PRBs that can be used for DL ​​transmission. The first PRB in PRG#4 is a PRB that can be used for DL ​​transmission. The last PRB in PRG#8 is a PRB that can be used for DL ​​transmission. The number of PRBs that can be used for DL ​​transmission in PRG#5, PRG#6, and PRG#7 is 0.

[0224] In this example, after determining the PRB for DL ​​transmission, the user equipment 101 may monitor or receive the PDSCH at an appropriate frequency domain location.

[0225] In the embodiment of the present disclosure, user equipment 101 obtains PRG configuration information applicable to an SBFD time domain unit by receiving first signaling sent by network device 102. Thus, in an SBFD scenario, user equipment 101 can accurately determine the first PRG size based on a reasonable PRG parameter configuration, thereby improving data transmission accuracy during SBFD time domain unit transmission.

[0226] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4b , FIG4b shows a communication processing method according to an exemplary embodiment. As shown in FIG4b , the method includes steps S4201 to S4202, specifically:

[0227] Step S4201: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0228] Among them, the implementation of step S4201 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0229] Step S4202: The user equipment 101 determines a first PRG size for DL ​​transmission according to the configuration of the first field in the first signaling.

[0230] The first field is used to indicate the PRG binding type.

[0231] In some embodiments, when the PRG configuration information is dedicated to the SBFD time domain unit, the user equipment 101 determines the first PRG size for DL ​​transmission according to the configuration of the first field in the first signaling.

[0232] In some possible implementations, the implementation of step S4202 can refer to the relevant implementation of step S4102 and will not be repeated here.

[0233] In some possible implementations, when the PRG configuration information is specifically for SBFD time domain units, it indicates that the network device 102 may have configured two sets of PRG configuration information, one set applicable to SBFD time domain units and the other set applicable to DL time domain units. Specifically, the network device 102 may add a new relevant field to the first signaling, such as RRC signaling, to configure the PRG configuration information applicable to SBFD.

[0234] For example, the PRG configuration information applicable to SBFD in the first signaling may refer to the following example:

[0235] For another example, the first signaling further configures PRG configuration information applicable to the DL time domain unit, which can be referred to in the following example:

[0236] In some possible implementations, the PRG binding type of the PRG is indicated by a first field in the first signaling, where the first field is, for example, prb-BundlingType_SBFD or prb-BundlingType. In the embodiment of the present disclosure, the first field is described using prb-BundlingType_SBFD as an example. The PRG binding type includes a static type (static) or a dynamic type (dynamic).

[0237] In some possible implementations, depending on the configuration of the first field in the first signaling, step S4202 may include different implementations, see steps S4202-1, S4202-2 or S4202-3.

[0238] In some embodiments, step S4202 may adopt the following step S4202-1, specifically:

[0239] Step S4202-1: When the first field is not configured in the first signaling, the user equipment 101 determines that the first PRG size is a first value.

[0240] For example, the first field is prb-BundlingType_SBFD, and the first value may correspond to 2 or n2.

[0241] In this embodiment, when prb-BundlingType_SBFD is not configured in the first signaling, the size of the first PRG is 2 PRBs.

[0242] In some embodiments, step S4202 may adopt the following step S4202-2, specifically:

[0243] Step S4202-2: When the first field configured in the first signaling indicates a static type, the user equipment 101 determines that the first PRG size is a second value or a broadband PRG.

[0244] For example, the second value may correspond to 4 or n4.

[0245] The wideband PRG (wideband) indicates that the user equipment 101 does not expect all DL PRBs scheduled by the network device 102 to be discontinuous.

[0246] In this embodiment, when the first field indicates a static type, such as staticBundling_SBFD, the user equipment 101 may determine that the first PRG size is n4 or wideband according to the configuration in bundleSize_SBFD.

[0247] In some possible implementations, step S4202 may adopt the following step S4202-2, specifically:

[0248] Step S4202 - 3 , when the first field configured in the first signaling indicates a dynamic type, the user equipment 101 determines the first PRG size according to the second field and the third field in the first signaling and the second signaling of the network device 102 .

[0249] The second field is used to indicate the first bundling size setting, and the third field is used to indicate the second bundling size setting; the second signaling includes or does not include the physical resource block PRB bundling size indication field.

[0250] For example, the second field is bundleSizeSet1_SBFD, and bundleSizeSet1_SBFD can be configured as 1 or 2 of {2, 4, wideband}.

[0251] The third field is, for example, bundleSizeSet2_SBFD, and bundleSizeSet2_SBFD can be configured as one of {2, 4, wideband}.

[0252] In one example, the second signaling may be DCI signaling. The network device 102 may send the second signaling in a scenario where the first field indicates a dynamic type. The user equipment 101 may receive the second signaling.

[0253] The PRB bundling size indication field is, for example, a PRB bundling size indicator field, which may occupy one or more bits.

[0254] In this embodiment, when the first field indicates a dynamic type, such as dynamicBundling_SBFD, the user equipment 101 may determine the first PRG size based on bundleSizeSet1_SBFD, bundleSizeSet2_SBFD, and DCI signaling. In this case, the first PRG size may adopt one of the following examples:

[0255] In the first example, when the second signaling includes a PRB bundling size indication field and the bit value of the PRB bundling size indication field is the third value, the user equipment 101 determines the first PRG size according to the first bundling size setting.

[0256] In this example, when the PRB bundling size indication field occupies 1 bit, the third value may be, for example, 1. When the PRB bundling size indication field occupies several bits, the third value may also be other set values.

[0257] In this example, the user equipment 101 determines the first PRG size according to the first bundling size setting bundleSizeSet1_SBFD, where bundleSizeSet1_SBFD can be configured as one or two of {2, 4, wideband}.

[0258] This example can be used in scenarios where only one value is configured for bundleSizeSet1_SBFD. In this case, the first PRG size uses the value configured for bundleSizeSet1_SBFD.

[0259] In the second example, when the PRB bundling size indication field is included in the second signaling and the bit value of the PRB bundling size indication field is the third value, the user equipment 101 determines the first PRG size according to the first bundling size setting, the PRB scheduled by the network device 102, and the corresponding bandwidth part BWP size.

[0260] In this example, when the PRB bundling size indication field occupies 1 bit, the third value may be, for example, 1. When the PRB bundling size indication field occupies several bits, the third value may also be other set values.

[0261] In this example, the user equipment 101 determines the first PRG size according to the first bundling size setting bundleSizeSet1_SBFD, where bundleSizeSet1_SBFD can be configured as one or two of {2, 4, wideband}.

[0262] If bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs exceeds Then the first PRG size P' BWP,i is wideband; otherwise, the first PRG size is n2 or n4.

[0263] Optionally, if bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs exceeds Then the first PRG size P′ BWP,i is wideband; otherwise the first PRG size is n2 or n4, where is the number of PRBs included in the frequency domain range available for DL ​​transmission in the SBFD time domain unit.

[0264] Optionally, in the SBFD time domain unit, a first frequency domain range and a second frequency domain range for DL ​​transmission are included. The first frequency domain range and the second frequency domain range are discontinuous. If bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous in the first frequency domain range and continuous in the second frequency domain range, and the number of scheduled PRBs exceeds Then the first PRG size P′ BWP,i is wideband; otherwise the first PRG size is n2 or n4, where The number of PRBs in the frequency domain that can be used for DL ​​transmission in the SBFD time domain unit. It can be understood that when judging whether the number of scheduled PRBs exceeds When the number of scheduled PRBs includes: the sum of the number of PRBs scheduled within the first frequency domain and the number of PRBs scheduled within the second frequency domain.

[0265] In one example, as shown in Figure 5, the number of RBs in which the DL frequency domain overlaps with the BWP is the number of RBs available for DL ​​transmission in the BWP. The frequency domain unavailable for DL ​​transmission includes the frequency domain corresponding to the GB and UL subbands, or the frequency domain corresponding to the UL subband.

[0266] In a third example, when the PRB bundling size indication field is not included in the second signaling, the first PRG size is determined according to the second bundling size setting.

[0267] In this example, when the PRB bundling size indication field does not exist, that is, the PRB bundling size indication field occupies 0 bits, the user equipment 101 determines the first PRB size according to the second bundling size setting bundleSizeSet2_SBFD, where bundleSizeSet2_SBFD can be configured as one of {2, 4, wideband}.

[0268] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the aforementioned embodiment and will not be repeated here.

[0269] In the embodiment of the present disclosure, the network device 102 may configure PRG configuration information applicable to the SBFD time domain unit for the user equipment 101, so that in the SBFD scenario, the user equipment 101 may determine the first PRG size of the SBFD time domain unit according to the newly added PRG configuration information.

[0270] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4c, FIG4c shows a communication processing method according to an exemplary embodiment. As shown in FIG4c, the method includes steps S4301 to S4302, specifically:

[0271] Step S4301: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0272] Among them, the implementation of step S4301 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0273] Step S4302: The user equipment 101 determines that the first PRG size is a first value.

[0274] In some possible implementations, when the PRG configuration information applies to SBFD time domain units and non-SBFD DL time domain units, and the second PRG size of the DL time domain unit is determined to be a wideband PRG according to the first signaling, the user equipment 101 determines the first PRG size to be the first value.

[0275] In some possible implementations, the implementation of step S4302 can refer to the relevant implementation of step S4102 and will not be repeated here.

[0276] In some possible implementations, the first value corresponds to 2 or n2.

[0277] In some possible implementations, the network device 102 is configured with only one set of PRG configuration information, such as the PRG configuration information in the first signaling, which can be referred to in the following example:

[0278] In some possible implementations, the user equipment 101 may determine the second PRG size based on the PRG configuration information. For example:

[0279] If the prb-BundlingType field is not configured in the first signaling, the size of the second PRG is equal to 2 PRBs.

[0280] If the prb-BundlingType configuration in the first signaling is a static type, the second PRG size is equal to 4 PRBs or is a broadband PRG, which can be determined according to the RRC configuration.

[0281] If the prb-BundlingType in the first signaling is configured as dynamic, and RRC configures bundleSizeSet1 and bundleSizeSet2, bundleSizeSet1 can be configured with one or two of {2, 4, wideband}, and bundleSizeSet2 can be configured with one of {2, 4, wideband};

[0282] At this time, when the PRB bundling size indicator field in DCI 1-1 does not exist, bundleSizeSet2 is used to determine the second PRG size;

[0283] When the PRB bundling size indicator field bit value in DCI 1-1 is 1 and bundleSizeSet1 is configured with 1 value, the value configured in bundleSizeSet1 is used as the second PRG size;

[0284] When the PRB bundling size indicator field bit value in DCI 1-1 is 1 and bundleSizeSet1 is configured with 2 values ​​(such as n2-wideband or n4-wideband), if the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs exceeds The second PRG size is wideband, otherwise the second PRG size is n2 or n4.

[0285] It can be understood that when the PRG size is configured as wideband, the user equipment 101 does not expect the scheduled PRBs to be discontinuous.

[0286] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the aforementioned embodiment and will not be repeated here.

[0287] In the embodiment of the present disclosure, in a scenario where a set of PRG configuration information is configured, when the second PRG size of the DL time domain unit is a wideband PRG, the user equipment 101 may determine the first PRG size of the non-wideband PRG in the SBFD time domain unit.

[0288] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4d, FIG4d shows a communication processing method according to an exemplary embodiment. As shown in FIG4d, the method includes steps S4401 to S4402, specifically:

[0289] Step S4401: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0290] Among them, the implementation of step S4401 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0291] Step S4402: The user equipment 101 determines a first PRG size according to the configuration of the first field in the first signaling.

[0292] In some possible implementations, when the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units, and the second PRG size of the DL time domain unit is determined to be a broadband PRG according to the first signaling, the user equipment 101 determines the first PRG size according to the configuration of the first field in the first signaling.

[0293] In some possible implementations, the implementation of step S4402 can refer to the relevant implementation of step S4102 and will not be repeated here.

[0294] In some possible implementations, the method for determining the size of the second PRG may refer to step S4302 and will not be repeated here.

[0295] In some possible implementations, the network device 102 is configured with only one set of PRG configuration information, such as the PRG configuration information in the first signaling, which can be referred to in the following example:

[0296] The first field is, for example, prb-BundlingType.

[0297] In some possible implementations, step S4402 may include one of the following examples:

[0298] In the first example, when the first field configured in the first signaling indicates a static type, the first PRG size is the first value or the second value.

[0299] For example, the first value may correspond to 2 or n2, and the second value may correspond to 4 or n4. In this example, the first field indicates staticBundling, and the first PRG size is n2 or n4.

[0300] In the second example, when the first field configured in the first signaling indicates a dynamic type and the received second signaling does not include a PRB bundling size indication field, the first PRG size is the first value or the second value.

[0301] For example, the first signaling is RRC signaling, and the second signaling is DCI signaling.

[0302] In this example, the first field indicates dynamicBundling, the first signaling configures the second field (bundleSizeSet1) and the third field (bundleSizeSet2), and there is no PRB bundling size indication field in DCI 1-1 or the PRB bundling size indication field occupies 0 bits, then the first PRG size is n2 or n4.

[0303] In the third example, when the first field configured in the first signaling indicates a dynamic type and the bit value of the PRB bundling size indication field in the second signaling is a third value, the first PRG size is the first value or the second value.

[0304] For example, taking the PRB bundling size indication field occupying 1 bit as an example, the third value is 1.

[0305] In this example, the first field indicates dynamicBundling, and the first signaling configures the second field (bundleSizeSet1) and the third field (bundleSizeSet2).

[0306] In DCI 1-1, the bit value of the PRB bundling size indication field is 1, and bundleSizeSet1 is configured with 1 value, and the first PRG size is n2 or n4.

[0307] In DCI 1-1, the PRB bundling size indication field is set to 1, and bundleSizeSet1 is configured with two values. The first PRG size is either n2 or n4. Optionally, the first PRG size is the value of the two values ​​configured for bundleSizeSet1, minus the wideband PRG size. For example, if bundleSizeSet1 is configured with {n2-wideband}, the PRG size is n2.

[0308] In some embodiments, in the above three examples, the first PRG size is n2 or n4, and in at least one example, the first PRG size is n4.

[0309] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the above embodiment and will not be repeated here.

[0310] In the embodiment of the present disclosure, in a scenario where a set of PRG configuration information is configured, when the second PRG size of the DL time domain unit is a wideband PRG, the user equipment 101 may determine the first PRG size of the non-wideband PRG in the SBFD time domain unit.

[0311] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4e , FIG4e shows a communication processing method according to an exemplary embodiment. As shown in FIG4e , the method includes steps S4501 to S4502, specifically:

[0312] Step S4501: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0313] Among them, the implementation of step S4501 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0314] In step S4502, the user equipment 101 determines that the first PRG size is the minimum value between the virtual resource block bundle size (VRB bundle size) and the resource block group (RBG) size.

[0315] In some possible implementations, when the PRG configuration information is applicable to an SBFD time domain unit and a non-SBFD DL time domain unit, and the second PRG size of the DL time domain unit is determined to be a wideband PRG according to the first signaling, the user equipment 101 determines the first PRG size to be the minimum value between the VRB bundling size and the RBG size.

[0316] In some possible implementations, the implementation of step S4502 can refer to the relevant implementation of step S4102 and will not be repeated here.

[0317] In some possible implementations, the method for determining the size of the second PRG may refer to step S4302 and will not be repeated here.

[0318] In some possible implementations, the user equipment 101 may determine the VRB bundling size according to the RRC parameter vrb-ToPRB-Interleaver. If the parameter vrb-ToPRB-Interleaver is not configured, the VRB bundling size may take a default value of 2.

[0319] In some possible implementations, the RBG size can be determined based on two parameters: for example, the number of PRBs included in a BWP and the parameter rbg-Size in the PDSCH-config information element of the RRC configuration. Alternatively, the RBG size corresponding to the number of PRBs included in a BWP is defined with two possible values, and the network device 102 can use one of these values ​​as the RBG size through RRC configuration.

[0320] It is understandable that the VRB bundling size or RBG size may also be determined in other ways.

[0321] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the aforementioned embodiment and will not be repeated here.

[0322] In an embodiment of the present disclosure, in a scenario where a set of PRG configuration information is configured, when the second PRG size of the DL time domain unit is a wideband PRG, the user equipment 101 may determine the first PRG size in the SBFD time domain unit according to the VRB bundling size and the RBG size.

[0323] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4f, FIG4f shows a communication processing method according to an exemplary embodiment. As shown in FIG4f, the method includes steps S4601 to S4602, specifically:

[0324] Step S4601: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0325] Among them, the implementation of step S4601 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0326] Step S4602: The user equipment 101 determines that the first PRG size is a wideband PRG in the first frequency domain range and / or the second frequency domain range.

[0327] In some possible implementations, when the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units, and the second PRG size of the DL time domain unit is determined to be a wideband PRG according to the first signaling, the user equipment 101 determines that the first PRG size is a wideband PRG in the first frequency domain range and / or the second frequency domain range.

[0328] In some possible implementations, the implementation of step S4602 can refer to the relevant implementation of step S4102 and will not be repeated here.

[0329] In some possible implementations, the method for determining the size of the second PRG may refer to step S4302 and will not be repeated here.

[0330] In some possible implementations, the SBFD time domain unit includes a first frequency domain range and a second frequency domain range for DL ​​transmission, wherein the first frequency domain range and the second frequency domain range are discontinuous.

[0331] In combination with the description of the foregoing embodiment, in the SBFD time domain unit, excluding the portion of the third frequency domain range, the remaining first frequency domain range and second frequency domain range are frequency domain ranges that can perform DL transmission.

[0332] For example, as shown in Figure 3 or Figure 5, the first frequency domain range may include a DL subband on one side of the UL subband, and the second frequency domain range may include a DL subband on the other side of the UL subband. In this embodiment, both DL subbands have DL transmission.

[0333] In some possible implementations, the user equipment 101 does not expect that the PRBs scheduled by the network device 102 are discontinuous in the first frequency domain range or the second frequency domain range.

[0334] For example, the user equipment 101 expects that the PRBs scheduled by the network device 102 in the first frequency domain range are continuous. In this case, the user equipment 101 expects that the size of the first PRG corresponding to the first frequency domain range is a wideband PRG.

[0335] Alternatively, the user equipment 101 expects that the PRBs scheduled by the network device 102 in the second frequency domain range are continuous. In this case, the user equipment 101 expects that the size of the first PRG corresponding to the second frequency domain range is a wideband PRG.

[0336] In some possible implementations, the user equipment 101 expects that the PRBs scheduled by the network device 102 are continuous in the first frequency domain range and the second frequency domain range, respectively. For example, the user equipment 101 expects that the first PRG size corresponding to the first frequency domain range is a wideband PRG, and the first PRG size corresponding to the second frequency domain range is a wideband PRG.

[0337] At this time, the user equipment 101 performs precoding on the PRBs scheduled in the first frequency domain range and the second frequency domain range, respectively.

[0338] In one example, when the first PRG size is a wideband PRG in the first frequency domain range and the second frequency domain range, the precoding matrices corresponding to the first frequency domain range and the second frequency domain range are the same or different.

[0339] For example, when the user equipment 101 performs precoding on the PRBs scheduled in the first frequency domain range and the second frequency domain range respectively, the precoding matrices are different.

[0340] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the above embodiment and will not be repeated here.

[0341] In the embodiment of the present disclosure, it is illustrated that when both DL subbands in the SBFD time domain unit have DL transmissions, the user equipment 101 may apply a wideband PRG approach.

[0342] It is understandable that when the DL time domain unit in the relevant protocol applies broadband PRG, the number of scheduled PRBs must exceed The number of PRBs may be less than This will cause the broadband PRG to be unusable. Therefore, in the embodiments of the present disclosure, the application scenarios of the broadband PRG can be expanded.

[0343] The embodiment of the present disclosure provides a communication processing method, which is executed by the user equipment 101. Referring to FIG4g, FIG4g shows a communication processing method according to an exemplary embodiment. As shown in FIG4g, the method includes steps S4701 to S4702, specifically:

[0344] Step S4701: User equipment 101 receives first signaling sent by a network device, where the first signaling includes precoding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit.

[0345] Among them, the implementation of step S4701 can refer to the relevant implementation of the aforementioned steps S2101 and S4101, and will not be repeated here.

[0346] Step S4702: When the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units, and when the first field configured in the first signaling indicates a dynamic type, the user equipment 101 determines a first PRG size based on whether the PRB scheduled by the network device 102 meets a first condition.

[0347] The bit value of the PRB bundling size indication field in the second signaling received from the network device 102 is the third value, and the first signaling indicates that the first bundling size setting is configured with two PRB sizes.

[0348] Among them, the implementation of step S4702 can refer to the relevant implementation of the aforementioned steps S2102 and S4102, and will not be repeated here.

[0349] In some possible implementations, the first signaling is, for example, RRC signaling, and the second signaling is, for example, DCI signaling.

[0350] In some possible implementations, when the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units, examples of the PRG configuration information in the first signaling can be found in the description of the aforementioned embodiment and will not be repeated here.

[0351] In some possible implementations, the first field (prb-BundlingType) configured in the first signaling indicates a dynamic type, such as dynamicBundling. The second field (bundleSizeSet1) indicates that the first bundling size setting is configured with two values, i.e., two PRG sizes, such as two n2-wideband or two n4-wideband.

[0352] In this implementation, the bit value of the PRB bundling size indication field in the second signaling is a third value. For example, taking the PRB bundling size indication field occupying 1 bit as an example, the third value may be 1.

[0353] In some possible implementations, step S4702 may adopt the following steps S4702-1 or S4702-2, specifically:

[0354] Step S4702-1: When the scheduled PRB meets the first condition, the first PRG is a wideband PRG.

[0355] In some embodiments, the first condition is related to whether the PRBs scheduled by the network device 102 are continuous and / or the number of PRBs.

[0356] In some embodiments, the first condition includes: the scheduled PRBs are continuous and the number of scheduled PRBs is greater than a fourth value; wherein the fourth value is determined according to the number of resource blocks RBs used for DL ​​transmission on the corresponding BWP in the SBFD time domain unit.

[0357] In one example, the fourth value is: in, It is the number of RBs available for DL ​​transmission in the BWP in the SBFD time domain unit.

[0358] In one example, as shown in Figure 5, the number of RBs in which the DL frequency domain overlaps with the BWP is the number of RBs available for DL ​​transmission in the BWP. The frequency domain unavailable for DL ​​transmission includes the frequency domain corresponding to the GB and UL subbands, or the frequency domain corresponding to the UL subband.

[0359] In this embodiment, if the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs is greater than The first PRG size is a wideband PRG.

[0360] In an example, the PRBs scheduled here are continuous and include: PRBs scheduled in the first frequency domain range are continuous and PRBs scheduled in the second frequency domain range are continuous.

[0361] That is, in this example, the scheduled PRBs may be continuous in the first frequency domain range and the second frequency domain range respectively, and the scheduled PRBs are not required to be continuous in the entire frequency domain range.

[0362] In one example, the first PRG size of the first frequency domain range and / or the second frequency domain range is a wideband PRG;

[0363] When the first PRG size in the first frequency domain range and the first PRG size in the second frequency domain range is a wideband PRG, the precoding matrices corresponding to the first frequency domain range and the second frequency domain range are the same or different.

[0364] The implementation of this example can refer to the relevant implementation of the aforementioned step S4602, which will not be repeated here.

[0365] In this example, the user equipment 101 performs precoding on the PRBs scheduled in the first frequency domain range and the second frequency domain range, respectively.

[0366] Step S4702-2: When the scheduled PRB does not meet the first condition, the first PRG size is the first value or the second value.

[0367] In some embodiments, not meeting the first condition includes at least one of the following:

[0368] The PRBs scheduled in the first frequency domain range are discontinuous;

[0369] The PRBs scheduled in the second frequency domain range are discontinuous;

[0370] The number of scheduled PRBs is less than or equal to a fourth value.

[0371] The method for determining the fourth value can be found in the description of the above example and will not be repeated here.

[0372] Optionally, failure to meet the first condition may also include that scheduled PRBs are discontinuous.

[0373] In this embodiment, when the first condition is not met, such as the scheduled PRBs are discontinuous or discontinuous within a certain frequency domain, and the number of scheduled PRBs is less than or equal to The first PRG size is n2 or n4, that is, the first PRG is a non-wideband PRG in the two values ​​of the second field (bundleSizeSet1) indicating the first bundling size setting configuration.

[0374] In some possible implementations, the method may further include step S4103. The implementation of step S4103 can be found in the description of the aforementioned embodiment and will not be repeated here.

[0375] In the embodiment of the present disclosure, when both DL subbands in the SBFD time domain unit have DL transmissions, the user equipment 101 determines whether the broadband PRG method can be applied according to whether the PRBs scheduled by the network device 102 meet the first condition.

[0376] The embodiment of the present disclosure provides a communication processing method, which is executed by the network device 102. Referring to FIG6 , FIG6 shows a communication processing method according to an exemplary embodiment. As shown in FIG6 , the method includes steps S6101 to S6202, specifically:

[0377] Step S6101: The network device 102 sends a first signaling to the user equipment 101, where the first signaling includes PRG configuration information applicable to the SBFD time domain unit.

[0378] The first signaling is used by the user equipment to determine a first PRG size for DL ​​transmission in the SBFD time domain unit.

[0379] Among them, the implementation method of step S6101 can refer to the description of relevant implementation methods such as steps S2101 and S4101, and will not be repeated here.

[0380] In some possible implementations, the SBFD time-domain unit may be an SBFD symbol or an SBFD time slot. For example, when the frequency domain range corresponding to a symbol includes both a DL subband and a UL subband, the symbol may be considered an SBFD symbol. If a time slot includes at least one SBFD symbol among multiple symbols, the time slot may be considered an SBFD time slot. For example, as shown in Figure 3, time slots 1-3 are SBFD time slots. Alternatively, if all symbols in a time slot are SBFD symbols, the time slot may be considered an SBFD time slot.

[0381] In some possible implementations, the first signaling may be RRC signaling.

[0382] In some possible implementations, the first signaling includes at least one of the following:

[0383] First field;

[0384] Second field;

[0385] The third field;

[0386] The first field is used to indicate the PRG binding type, the second field is used to indicate the first binding size setting, and the third field is used to indicate the second binding size setting.

[0387] In one example, the example of the first signaling can be found in the description of the aforementioned embodiment and will not be repeated here.

[0388] When the PRG configuration information is dedicated to the SBFD time domain unit, that is, when the network device 102 is configured with two sets of PRG configuration information, the first field may be prb-BundlingType_SBFD, the second field may be bundleSizeSet1_SBFD, and the third field may be bundleSizeSet2_SBFD.

[0389] When the PRG configuration information is applicable to SBFD time domain units and DL time domain units, that is, the network device 102 is configured with only one set of PRG configuration information, the first field may be prb-BundlingType, the second field may be bundleSizeSet1, and the third field may be bundleSizeSet2.

[0390] The second field can configure the first binding size to be set to 1 or 2 of {2, 4, wideband}, and the third field can configure the second binding size to be set to 1 of {2, 4, wideband}.

[0391] In some possible implementations, the PRG configuration information is dedicated to the SBFD time domain unit.

[0392] The embodiment in this scenario can refer to the relevant implementation method in the embodiment of Figure 4b, which will not be repeated here.

[0393] In some embodiments, when the first field is configured in the first signaling, the first PRG size is a first value.

[0394] The implementation of this embodiment can refer to the relevant implementation of step S4202, which will not be repeated here.

[0395] In some embodiments, when the first field configured in the first signaling indicates a static type, the first PRG size is a second value or width PRG.

[0396] The implementation of this embodiment can refer to the relevant implementation of step S4202, which will not be repeated here.

[0397] In some embodiments, when the first field configured in the first signaling indicates a dynamic type, the first PRG size is determined by the user equipment according to the second field and the third field in the first signaling and the second signaling of the network device.

[0398] The implementation of this embodiment can refer to the relevant implementation of step S4202, which will not be repeated here.

[0399] In some embodiments, when the first field configured in the first signaling indicates a dynamic type, the method further includes the following step S6102, specifically:

[0400] Step S6102: The network device 102 sends a second signaling to the user equipment. The second signaling includes or does not include a PRB bundling size indication field.

[0401] In one example, the second signaling is, for example, DCI signaling. In this case, the first PRG size may adopt one of the following examples:

[0402] In the first example, when the bit value of the PRB bundling size indication field in the second signaling is the third value, the user equipment 101 determines the first PRG size according to the first bundling size setting.

[0403] In this example, when the PRB bundling size indication field occupies 1 bit, the third value may be, for example, 1. This example may be used in a scenario where bundleSizeSet1_SBFD is configured with only one value, and the first PRG size adopts the value configured in bundleSizeSet1_SBFD.

[0404] In the second example, when the bit value of the PRB bundling size indication field in the second signaling is the third value, the user equipment 101 determines the first PRG size according to the first bundling size setting, the PRBs scheduled by the network device 102 and the corresponding bandwidth part BWP size.

[0405] In this example, the user equipment 101 determines the first PRG size according to the first bundling size setting bundleSizeSet1_SBFD, where bundleSizeSet1_SBFD can be configured as one or two of {2, 4, wideband}.

[0406] If bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs exceeds Then the first PRG size P′ BWP,i is wideband; otherwise, the first PRG size is n2 or n4.

[0407] Optionally, if bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous and the number of scheduled PRBs exceeds Then the first PRG size P′ BWP,i is wideband; otherwise the first PRG size is n2 or n4, where is the number of PRBs included in the frequency domain range available for DL ​​transmission in the SBFD time domain unit.

[0408] Optionally, in the SBFD time domain unit, a first frequency domain range and a second frequency domain range for DL ​​transmission are included. The first frequency domain range and the second frequency domain range are discontinuous. If bundleSizeSet1_SBFD is configured with two values, such as n2-wideband or n4-wideband, when the PRBs scheduled by the network device 102 are continuous in the first frequency domain range and continuous in the second frequency domain range, and the number of scheduled PRBs exceeds Then the first PRG size P′ BWP,i is wideband; otherwise the first PRG size is n2 or n4, where The number of PRBs in the frequency domain that can be used for DL ​​transmission in the SBFD time domain unit. It can be understood that when judging whether the number of scheduled PRBs exceeds When the number of scheduled PRBs includes: the sum of the number of PRBs scheduled within the first frequency domain and the number of PRBs scheduled within the second frequency domain.

[0409] In one example, as shown in Figure 5, the number of RBs in which the DL frequency domain overlaps with the BWP is the number of RBs available for DL ​​transmission in the BWP. The frequency domain unavailable for DL ​​transmission includes the frequency domain corresponding to the GB and UL subbands, or the frequency domain corresponding to the UL subband.

[0410] In a third example, when the PRB bundling size indication field is not included in the second signaling, the first PRG size is determined according to the second bundling size setting.

[0411] In this example, when the PRB bundling size indication field does not exist, that is, the PRB bundling size indication field occupies 0 bits, the user equipment 101 determines the first PRB size according to the second bundling size setting bundleSizeSet2_SBFD, where bundleSizeSet2_SBFD can be configured as one of {2, 4, wideband}.

[0412] In some possible implementations, the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units.

[0413] The embodiments in this scenario can refer to the relevant implementation methods in the embodiments of Figures 4c to 4f, which will not be repeated here.

[0414] In some embodiments, if the second PRG size of the DL time domain unit is a wideband PRG, the first PRG size is a first value.

[0415] In some embodiments, if the second PRG size of the DL time domain unit is a wideband PRG, the first PRG size is determined by the user equipment according to the configuration of the first field in the first signaling.

[0416] In one example, the first PRG size satisfies one of the following:

[0417] When the first field configured in the first signaling indicates a static type, the first PRG size is the first value or the second value;

[0418] When the first field configured in the first signaling indicates a dynamic type and the received second signaling does not include a PRB bundling size indication field, the first PRG size is the first value or the second value;

[0419] When the first field configured in the first signaling indicates a dynamic type and the bit value of the PRB bundling size indication field in the second signaling is the third value, the first PRG size is the first value or the second value.

[0420] In some embodiments, if the second PRG size of the DL time domain unit is a wideband PRG, the first PRG size is a minimum value between the VRB bundling size and the RBG size.

[0421] In some embodiments, in the SBFD time domain unit, a first frequency domain range and a second frequency domain range for DL ​​transmission are included;

[0422] If the second PRG size of the DL time domain unit is a wideband PRG, the first PRG size is a wideband PRG in the first frequency domain range and / or the second frequency domain range; wherein the first frequency domain range is discontinuous with the second frequency domain range.

[0423] In some possible implementations, the PRG configuration information is applicable to SBFD time domain units and non-SBFD DL time domain units. When the first field configured in the first signaling indicates a dynamic type, the first PRG size is determined based on whether the PRB scheduled by the network device meets the first condition.

[0424] The bit value of the PRB bundling size indication field in the second signaling sent is the third value, and the first signaling indicates that the first bundling size setting is configured with two PRB sizes.

[0425] Optionally, the embodiment in this scenario can refer to the relevant implementation method in the embodiment of Figure 4g, which will not be repeated here.

[0426] In some embodiments, when the scheduled PRB satisfies a first condition, the first PRG is a wideband PRG;

[0427] When the scheduled PRB does not meet the first condition, the first PRG size is the first value or the second value.

[0428] In some embodiments, the first condition includes:

[0429] The scheduled PRBs are continuous, and the number of scheduled PRBs is greater than a fourth value;

[0430] The fourth value is determined according to the number of resource blocks (RBs) used for DL ​​transmission on the corresponding BWP in the SBFD time domain unit.

[0431] In one example, the scheduled PRBs consecutively include:

[0432] The PRBs scheduled in the first frequency domain range are continuous, and the PRBs scheduled in the second frequency domain range are continuous.

[0455] In some embodiments, the PRG size corresponds to the first PRG size in the aforementioned embodiments.

[0456] During the implementation of steps S7101 to S7103, the method includes the following implementation aspects:

[0457] Example 1:

[0458] RRC adds a set of PRG related information for SBFD time slots. When PDSCH is in the SBFD time slot, the PRG size is determined according to the PRG configuration information of the SBFD time slot configured by RRC and / or the DCI indication information.

[0459] Example:

[0460] The implementation of this embodiment 1 may correspond to the description of the embodiment related to FIG4 b above, and will not be repeated here.

[0461] Example 2:

[0462] RRC configures only one set of PRG related information for DL ​​time slots and SBFD time slots. In SBFD time slots, the DL PRBs allocated to the UE are in frequency domain range 1 and frequency domain range 2 available for DL ​​transmission. When frequency domain range 1 and frequency domain range 2 are discontinuous in the frequency domain:

[0463] Example 2-1:

[0464] According to the RRC configuration and DCI indication, if the DL time slot PRG size is wideband, the SBFD time slot has a different understanding of the PRG size from the DL time slot.

[0465] In this embodiment, the following situations may be included:

[0466] Example 2-1-1: The SBFD timeslot PRG size is n2.

[0467] Among them, the implementation method of Example 2-1-1 can correspond to the description of the relevant embodiment of Figure 4c above, and will not be repeated here.

[0468] Example 2-1-2: In the following case 1, case 2-1, case 2-2, and case 2-3, the SBFD timeslot PRG size is n4 or n2, and at least one is n4;

[0469] Case1: prb-BundlingType is static;

[0470] Case 2: prb-BundlingType is dynamic, and RRC configures bundleSizeSet1 and bundleSizeSet2;

[0471] Case 2-1: The PRB bundling size indicator field in DCI 1-1 is 0 bits / this field does not exist;

[0472] Case 2-2: The PRB bundling size indicator field in DCI 1-1 is 1, and bundleSizeSet1 is configured with 1 P′ BWP,i ;

[0473] Case 2-3: The PRB bundling size indicator field in DCI 1-1 is 1, and bundleSizeSet1 is configured with 2 P′ BWP,i ;

[0474] Optionally, P′ BWP,i 2 P's configured for bundleSizeSet1 BWP,i The one remaining after removing wideband.

[0478] Example 2-1-3: The PRG size of the SBFD time slot is the minimum value of the VRB bundle size and the RBG size.

[0479] The VRB bundle size is determined by the RRC parameter vrb-ToPRB-Interleaver. When the RRC parameter vrb-ToPRB-Interleaver is not configured, the VRB bundle size defaults to 2.

[0480] The RBG size is determined by the number of PRBs included in the BWP and the parameter rbg-Size in the PDSCH-config information element of the RRC configuration.

[0481] The VRB bundle size and RBG size may also be determined by other methods.

[0482] Among them, the implementation method of Example 2-1-3 can correspond to the description of the relevant embodiment of Figure 4e above, and will not be repeated here.

[0483] Example 2-2:

[0484] According to the RRC configuration and DCI indication, the PRG size of the DL time slot and SBFD time slot is wideband.

[0485] The UE does not expect the PRBs scheduled in frequency domain range 1 or frequency domain range 2 to be discontinuous (the UE expects the PRBs scheduled in frequency domain range 1 and frequency domain range 2 to be continuous);

[0486] The UE performs wideband precoding on the PRBs scheduled in the frequency domain range 1 and the frequency domain range 2 respectively, and the precoding matrices in the frequency domain range 1 and the frequency domain range 2 may be different.

[0487] Among them, the implementation method of Example 2-2 can correspond to the description of the relevant embodiment of Figure 4f above, and will not be repeated here.

[0488] Example 2-3:

[0489] If prb-BundlingType is dynamic, the PRB bundling size indicator field value in DCI 1-1 is 1, and bundleSizeSet1 is configured with 2 P′ BWP,i (n2-wideband or n4-wideband), then:

[0490] Example 2-3-1: If the scheduled PRBs are continuous and the number of scheduled PRBs exceeds is wideband, otherwise it is n2 / n4.

[0491] in, is the number of RBs available for DL ​​transmission in the BWP in the SBFD time slot. The number of RBs in which the DL frequency domain range overlaps with the BWP in the following optional examples 1 and 2 is the number of RBs available for DL ​​transmission in the BWP.

[0492] Option 1: The frequency domain range that cannot be used for DL ​​transmission includes the frequency domain range of GB and UL sub-band;

[0493] Option 2: the frequency domain range unavailable for DL ​​transmission includes the frequency domain range of the UL subband.

[0494] Example 2-3-2: In the SBFD time slot, the DL PRBs allocated to the UE are in the frequency domain range 1 and the frequency domain range 2 that can be used for DL ​​transmission, and the frequency domain range 1 and the frequency domain range 2 are not continuous in the frequency domain. If the scheduled PRBs are continuous in the frequency domain range 1 and the frequency domain range 2, and the number of scheduled PRBs exceeds P′ BWP,i is wideband, otherwise it is n2 / n4.

[0495] in, is the number of RBs available for DL ​​transmission in the BWP in the SBFD time slot. The number of RBs in which the DL frequency domain range overlaps with the BWP in the following optional examples 1 and 2 is the number of RBs available for DL ​​transmission in the BWP.

[0496] Option 1: The frequency domain range that cannot be used for DL ​​transmission includes the frequency domain range of GB and UL sub-band;

[0497] Option 2: the frequency domain range unavailable for DL ​​transmission includes the frequency domain range of the UL subband.

[0498] Among them, the implementation of Example 2-3 can correspond to the description of the relevant embodiment of Figure 4g above, and will not be repeated here.

[0499] Example 3:

[0500] The PRG size determination method may apply existing protocols, and the PRBs in the PRG that overlap with the frequency domain range available for DL ​​transmission are the PRBs available for DL ​​transmission included in the PRG.

[0501] The implementation of Example 3 may refer to the relevant implementation of the aforementioned step S4103 and will not be repeated here.

[0502] For example, as shown in FIG5 , GB and UL subbands are not available for DL ​​transmission, and the PRGs of the BWP include PRGs #0, #1, #2, #3, #4, #5, #6, #7, #8, #9, #10, #11, and #12. Then:

[0503] The PRBs in PRG#0, #1, #2, #3, #9, #10, #11, and #12 are all PRBs that can be used for DL ​​transmission;

[0504] The first PRB in PRG#4 is the PRB that can be used for DL ​​transmission;

[0505] The last PRB in PRG#8 is the PRB that can be used for DL ​​transmission;

[0506] The number of PRBs available for DL ​​transmission in PRG #5, #6, and #7 is 0.

[0507] In the embodiments of this disclosure, when the PRG is configured / indicated as wideband in an SBFD time slot, the PRG size is determined differently than when it is configured / indicated as wideband in a DL time slot. Furthermore, when the PRG type is configured as dynamic, the conditions for adopting wideband in an SBFD time slot differ from those in a DL time slot, and the number of PRBs included in the PRG also differs from that in a DL time slot scenario.
