Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0028] Hereinafter, the terms “first”, “second”, and the like are used only for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined by the terms “first”, “second”, and the like can explicitly or implicitly include one or more of the features.

[0029] In the description of the present disclosure, unless otherwise specified, “ / ” means “or”, for example, A / B can mean A or B. “And / or” in the present disclosure is only used to describe the association relationship of the associated objects, which means that there can be three kinds of relationships.

[0030] In the following, the technologies involved in the present solution will be explained.

[0031] 1. SBFD subband

[0032] For a terminal in a radio resource control (RRC) connected state, the SBFD technology can be used to improve the uplink (UL) coverage of a time division duplexing (TDD) system, reduce the latency of UL transmission, and increase the capacity of UL transmission. In related technologies, an UL subband can be configured in a downlink (DL) symbol, which can also be configured with a DL subband. That is, the UL subband and the DL subband (which can also be referred to as an SBFD subband) are simultaneously configured in a DL symbol or a flexible symbol (F symbol). The DL symbol or the F symbol (i.e., the symbol configured with the SBFD subband) can also be referred to as an SBFD symbol, and a symbol that is not configured with an SBFD subband can be referred to as a non-SBFD symbol.

[0033] However, the SBFD subband (DL subband and UL subband) is prohibited from being configured in a UL symbol. In this case, the UL BWP in the UL symbol (i.e., the non-SBFD symbol) is used for uplink transmission, and the UL subband in the SBFD symbol is used for uplink transmission. However, the interference conditions of the UL BWP and the UL subband are different, so corresponding uplink transmission needs to provide corresponding transmission parameters and configuration parameters to adapt to the uplink transmission in the UL BWP subband and the UL subband, respectively, which will complicate the design of uplink transmission in the communication system.

[0034] It should be noted that in related technologies, the subband full duplex technology can include the following features: the base station has the capability to simultaneously receive (in the UL subband) and transmit (in the DL subband), that is, to receive and transmit in the same time domain resource. The terminal does not have the capability to simultaneously perform receiving (in the DL subband) and transmitting (in the UL subband), that is, cannot transmit and receive in the same time domain resource. In this way, the UL subband and the DL subband are configured in the same OFDM symbol / slot and are frequency-division. In some embodiments, the symbol configured with the SBFD subband is referred to as an SBFD symbol. The slot containing the SBFD symbol is referred to as an SBFD slot. The symbol that is not configured with the SBFD subband is referred to as a non-SBFD symbol (i.e., a regular symbol). The slot that does not contain the SBFD symbol is referred to as a non-SBFD slot.

[0035] 2.IBFD subband

[0036] To further improve system efficiency, full duplex technology is researched, for example, IBFD technology. That is, a time-frequency resource is configured in the carrier bandwidth of a carrier. In the time-frequency resource, the base station can perform simultaneous transmission and reception at the same frequency. For example, consecutive resource blocks (RBs) are configured as IBFD subbands in the carrier bandwidth, and the IBFD subbands are configured in all or part of the symbols, thereby forming an IBFD operation resource. However, how to configure the SBFD subband and / or the IBFD subband is a technical problem to be solved at present.

[0037] In an implementation manner, an SBFD subband can be configured in a DL BWP in a DL symbol or slot, and the SBFD subband generally includes at least one DL subband and one UL subband. For example, in a 100 MHz TDD carrier, 20 consecutive RBs are configured as: the UL subband is in the DL BWP (or in the DL symbol / slot), and the remaining frequency domain resources of the DL BWP are the DL subband (a measurement gap can not be configured), or a DL is also configured in the DL BWP (or in the DL symbol / slot). In this way, in the DL symbol / slot, the UL subband can be used for uplink transmission, and the DL subband can be used for downlink transmission. As shown in FIG. 1, an SBFD subband includes one UL subband and at least one DL subband, and there is a gap between the two subbands. This frequency domain pattern is generally referred to as DUD (based on frequency domain structure). As shown in FIG. 2, an SBFD subband includes one UL subband and at least one DL subband, and the UL subband is located below the DL subband, and there is a gap between the two subbands. This frequency domain pattern is generally referred to as DU (based on frequency domain structure). It should be understood that the above-mentioned configuration operation of the SBFD subband is performed in a DL bandwidth part (BWP) and a UL BWP pair, and the DL BWP and the UL BWP pair are center frequency aligned.

[0038] Exemplarily, part or all of the carrier bandwidth of a carrier is configured as an IBFD subband, and the IBFD is configured in all or part of the symbols. As shown in FIG. 3, part of the bandwidth of two IBFD resources is configured as an IBFD subband. It should be understood that the symbol configured with the IBFD subband is referred to as an IBFD symbol. The slot containing the IBFD symbol is referred to as an IBFD slot. The symbol not configured with the IBFD subband is referred to as a non-IBFD symbol (that is, a conventional symbol). The slot not containing the IBFD symbol is referred to as a non-IBFD slot.

[0039] To this end, the embodiment of the present disclosure provides a subband configuration updating method. A first node can send first information, and the first information is used to configure / update the configuration of a subband in a first frequency domain resource. The subband includes a subband full duplex (SBFD) subband and / or an in-band full duplex (IBFD) subband. In this way, the SBFD subband and / or the IBFD subband can be configured for a communication system through the first information between the first node and a second node, so that the problem of how to configure the subband for the communication system can be solved, and the transmission efficiency of the communication system can be further improved.

[0040] The subband configuration updating method provided by the embodiment of the present disclosure can be applied to systems of various communication modes. For example, the subband configuration updating method provided by the embodiment of the present disclosure can be applied to systems including but not limited to a long term evolution (LTE) system, various versions based on LTE evolution, a 5th generation mobile communication technology (5G) system, or a multi-communication integrated system. In addition, the subband configuration updating method provided by the embodiment of the present disclosure can also be applied to a future-oriented communication system, etc.

[0041] Exemplarily, the above-mentioned subband configuration updating method can be applied to a communication system as shown in FIG. 4. As shown in FIG. 4, the communication system includes a first node 401 and a second node 402.

[0042] The first node 401 and the second node 402 are communicatively connected. The first node 401 can be at least one of a base station, an Internet of Things device, and various transmitting devices. The second node 402 can be at least one of a terminal, a user equipment (UE), an Internet of Things device, and various receiving devices. FIG. 4 takes the first node 401 as a base station and the second node 402 as a terminal as an example for illustration.

[0043] In the embodiment of the present disclosure, the first node 401 can send first information to the second node 402. Correspondingly, the second node 402 can receive the first information sent by the first node 401, so as to configure the SBFD subband and / or the IBFD subband based on the first information.

[0044] It should be noted that FIG. 4 is only an exemplary framework diagram, and the number of devices included in FIG. 4 and the names of various devices are not limited. In addition to the devices shown in FIG. 4, the communication system can also include other devices, such as a relay node, etc.

[0045] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0046] The sub-band configuration updating method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0047] The sub-band configuration updating method provided by the embodiments of the present disclosure can be applied to the first node 401 in the communication system shown in FIG. 4. FIG. 5 shows a flowchart of a sub-band configuration updating method. As shown in FIG. 5, the sub-band configuration updating method includes the following S501.

[0048] In S501, first information is sent.

[0049] The first information is used to configure / update the configuration of a sub-band in a first frequency domain resource. The sub-band includes an SBFD sub-band and / or an IBFD sub-band. In some embodiments, the first frequency domain resource can be any frequency domain resource.

[0050] The first node can configure / update the configuration of the sub-band in the first frequency domain resource. The first node can send the first information to the second node, so that the second node configures or updates the sub-band based on the first information, thereby solving the technical problem of how to configure or update the sub-band in the communication system. In addition, since the sub-band includes the SBFD sub-band and / or the IBFD sub-band, the first node and the second node can improve the communication efficiency when transmitting through the sub-band.

[0051] It should be noted that the first node can configure at least one frequency domain bandwidth (i.e., a downlink sub-band) used for downlink transmission and at least one frequency domain bandwidth (i.e., an uplink sub-band) used for uplink transmission in a carrier bandwidth corresponding to one TDD carrier, and it is agreed that the configured UL sub-band and DL sub-band are valid in all time domains by default. For example, they are valid in all orthogonal frequency division multiplexing (OFDM) symbols. For another example, if the TDD carrier is configured with a DL-UL pattern frame structure, the UL sub-band and the DL sub-band are also valid in all symbol types, including UL symbols.

[0052] Based on the above configuration, a TDD carrier performing DL transmission and UL transmission based on time division manner is configured to perform DL transmission and UL transmission based on frequency division manner. In this way, the TDD carrier can provide continuous DL transmission occasions and continuous UL transmission occasions, thereby effectively reducing the waiting delay of DL and UL data transmission, that is, after the above configuration of a TDD carrier, frequency division duplexing (FDD) frequency division multiplexing can be realized. In some embodiments, the second node can also configure the IBFD subband as the above carrier.

[0053] In an implementation manner, in a case where the first information is used for configuring the subband configuration, the subband can include the SBFD subband and / or the IBFD subband. The first node can configure the SBFD subband and / or the IBFD subband through the first information, and the configured SBFD subband and / or IBFD subband can include two cases, which will be introduced below. It should be noted that in the embodiments of the present disclosure, the UL subband described below refers to the SBFD UL subband, and the DL subband described below refers to the SBFD DL subband.

[0054] Case one

[0055] The first node can directly configure the SBFD subband (including the DL subband and the UL subband) and / or the IBFD subband in the carrier bandwidth of one carrier. For example, the frequency domain size and position of at least one DL subband are configured, the frequency domain size and position of at least one UL subband are configured, and only one IBFD subband is configured. Moreover, it can be defaulted that the above configuration is effective in all time domain resources (for example, OFDM symbol, slot, subframe). It should be understood that in a case where the subband includes the SBFD subband and the IBFD subband, the first information is used for configuring the SBFD subband and the IBFD subband, and the SBFD subband and the IBFD subband do not overlap; in a case where the subband includes the IBFD subband, the first information is used for configuring the IBFD subband; in a case where the subband includes the SBFD subband, the first information is used for configuring the SBFD subband.

[0056] Case two

[0057] The first node can directly configure the SBFD subband (including the DL subband and the UL subband) in the carrier bandwidth of one carrier. At this time, the first information is used for configuring the SBFD subband. For example, the frequency domain size and position of one or more DL subbands are configured, and the frequency domain size and position of one or more UL subbands are configured. Moreover, it is defaulted that the above configuration is effective in all time domain resources (for example, OFDM symbol, slot, subframe).

[0058] Further, the first node and the second node can agree that the DL subband and the UL subband in the SBFD subband can overlap in the frequency domain resource, and the overlapping part is the IBFD subband. Therefore, in the case that the DL subband and the UL subband exist overlapping frequency domain resources, the first information is used to configure the SBFD subband, and the IBFD subband is obtained based on the frequency domain intersection of the DL subband and the UL subband. In the IBFD subband, the first node can simultaneously perform uplink transmission and downlink transmission. Except for the IBFD subband, the downlink transmission is limited in the frequency domain resource in the DL subband which does not overlap with the UL subband, and the uplink transmission is limited in the frequency domain resource in the UL subband which does not overlap with the DL subband. As shown in FIG. 6, the UL subband and the DL subband are effective in slot0-slot9 (slot 0-slot 9), and the part where the UL subband and the DL subband overlap is regarded as the IBFD subband, the part in the UL subband which does not overlap performs SBFD-based uplink transmission, and the part in the DL subband which does not overlap performs SBFD-based downlink transmission.

[0059] In addition, for case two, the corresponding time domain resources (for example, OFDM symbol, slot, etc.) can also be configured for the UL subband and the DL subband. In this way, the DL subband and the UL subband can be valid only in part of the time domain resources. Accordingly, the frequency domain resources where the DL subband and the UL subband overlap are still used for IBFD operation (i.e., IBFD-based transmission), and the IBFD operation can also be valid only in part of the time domain resources.

[0060] In addition, in the configured time domain resources, the frequency domain resources where the DL subband and the UL subband overlap are regarded as the IBFD subband. That is, the time domain resources of the IBFD subband can be configured by signaling. In this way, in other time domain resources (i.e., resources other than the time domain resources configured by signaling for the IBFD subband), the overlapping part of the DL subband and the UL subband is not regarded as the IBFD subband.

[0061] In an implementation manner, for the above-mentioned case one and case two, the IBFD subband can be limited in the following examples 1 to 5 in part of the symbol types.

[0062] Example 1, the IBFD is limited in the DL symbol, so as to reduce the interference on the uplink transmission of the traditional UL symbol.

[0063] Example 2, the IBFD is limited in the F symbol, so as to adjust the time domain influence of the IBFD subband by adjusting the number of F symbols. Since the proportion of the F symbol in the communication system is small, the influence on the communication system is small.

[0064] Example 3, the IBFD subband is limited to be invalid in the IBFD subband in the DL symbol and the UL symbol.

[0065] Example 4, IBFD subbands are restricted to be determined based on (UE group or UE specific) DCI (downlink control information) indication to determine the symbol location of IBFD subbands.

[0066] Example 5, if a new type of frame structure or a new type of symbol is configured in a carrier, i.e. a symbol type configured to perform simultaneous intra-frequency transmission, denoted as DL&UL symbol type, IBFD subbands are restricted to be in DL&UL symbol type.

[0067] In Example 2 and Example 3, for the DL subbands and UL subbands configured based on Case 2, and the IBFD subbands obtained by overlapping, the following restriction can be performed: in a DL symbol or a UL symbol, a configured DL subband can only use the frequency domain resource that is not overlapped with a UL subband to perform downlink transmission, and a configured UL subband can only use the frequency domain resource that is not overlapped with a DL subband to perform uplink transmission.

[0068] It should be noted that the way of configuring SBFD subbands and IBFD subbands based on the above manner is semi-static, which cannot well adapt to the change of DL load and UL load. Therefore, after the subbands are configured, dynamic adjustment of the subbands needs to be considered, so as to better adapt to the change of DL load and UL load. Therefore, the first information can be used to update the SBFD subbands and / or the IBFD subbands. For example, the signaling of configuring the above DL subbands and UL subbands is transmitted based on dynamic signaling (e.g. DCI in PDCCH (physical downlink control channel)), so as to realize the configuration of the DL subbands and the UL subbands. In some embodiments, the dynamic signaling can be the first information.

[0069] In some embodiments, the first information is associated with at least one of the following functions: A, expanding the frequency domain bandwidth of the SBFD DL subband (including but not limited to: changing the entire or partial bandwidth of the IBFD subband to a frequency domain bandwidth for DL transmission only, thereby increasing the bandwidth of the DL subband); B, expanding the frequency domain bandwidth of the SBFD UL subband (including but not limited to: changing the entire or partial bandwidth of the IBFD subband to a frequency domain bandwidth for UL transmission only, thereby increasing the bandwidth of the UL subband); C, reducing the frequency domain bandwidth of the SBFD DL subband (including but not limited to: changing the partial or entire bandwidth of the DL subband to the bandwidth of the IBFD subband, or to the bandwidth of the UL subband); D, reducing the frequency domain bandwidth of the SBFD UL subband (including but not limited to: changing the partial or entire bandwidth of the UL subband to the bandwidth of the IBFD subband, or to the frequency domain bandwidth of the DL subband); E, canceling the SBFD DL subband (including but not limited to: changing the entire bandwidth of the DL subband to the frequency domain bandwidth of the UL subband, or to the bandwidth of the IBFD subband); F, canceling the SBFD UL subband (including but not limited to: changing the entire bandwidth of the UL subband to the frequency domain bandwidth of the DL subband, or to the bandwidth of the IBFD); G, canceling the IBFD subband (including but not limited to: changing the entire bandwidth of the IBFD subband to the frequency domain bandwidth of the DL subband, or to the frequency domain bandwidth of the UL subband); H, canceling at least one of the configured three subbands (i.e., the SBFD DL subband, the SBFD UL subband, and the IBFD subband) and keeping the subband (i.e., the subband not canceled) using the transmission direction indicated by the signaling (e.g., the first information); I, expanding the frequency domain bandwidth of the IBFD subband; J, reducing the frequency domain bandwidth of the IBFD subband; K, canceling the IBFD subband (including but not limited to: changing the entire bandwidth of the IBFD subband to the frequency domain bandwidth of the DL subband, or to the frequency domain bandwidth of the UL subband).

[0070] In an implementation manner, in the case that the first information is used for configuring the SBFD subband and / or the IBFD subband, the first information can also be used for associating at least one of the following: L, configuring the frequency domain bandwidth of the SBFD DL subband; M, configuring the frequency domain bandwidth of the SBFD UL subband; N, configuring the frequency domain bandwidth of the IBFD subband.

[0071] In addition, in the case that the first information is used for updating the SBFD subband and / or the IBFD subband, the subband can also be updated (or adjusted) in the following ways one to eight. The eight ways will be introduced respectively below.

[0072] Way one

[0073] The first information comprises at least one of the following: a first parameter, a second parameter, a third parameter, a fourth parameter. The first parameter is used to indicate the number of scheduling units used for downlink at the beginning of a subband configuration period. The second parameter is used to indicate the number of scheduling units used for uplink at the end of a subband configuration period. The third parameter is used to indicate the number of consecutive symbols used for downlink at the beginning of scheduling units after the last complete scheduling unit used for downlink in a subband configuration period. The fourth parameter is used to indicate the number of consecutive symbols used for uplink at the end of scheduling units before the first complete scheduling unit used for uplink in a subband configuration period.

[0074] The first node configures or agrees with the second node a subband configuration period. For example, the first node configures a frame period of n times as a subband configuration period. In a subband configuration period, the update of the DL subband and the UL subband is configured in scheduling units and / or symbols. The value of n is 1, 2, 3, 4, 5,... etc. The value of n is preferably 1.

[0075] For example, for a subband configuration period, the transmission direction of a scheduling unit, e.g. DL or UL, is indicated by signaling, e.g. the first information. In the period, the DL scheduling unit / symbol is indicated as DL, then the UL subband is cancelled, i.e. all the carrier bandwidth of the TDD carrier is used for DL transmission. In the period, the UL scheduling unit / symbol is indicated as UL, then the DL subband is cancelled, i.e. all the carrier bandwidth of the TDD carrier is used for UL transmission. If a scheduling unit / symbol is not indicated the transmission direction, then the DL subband and the UL subband are maintained in the scheduling unit / symbol. For example, the signaling design can be the design of the first information.

[0076] It is noted that the transmission direction of the scheduling unit / symbol configured by the signaling structure is consistent with the related frame structure. For example, in a period, the front is DL symbol, the back is UL symbol, and the middle is F symbol. However, the signaling can be reinterpreted as follows: for SBFD subband (i.e. DL subband and UL subband), during the duration of the scheduling unit or symbol which is not configured with transmission direction, the SBFD DL subband and the SBFD UL subband are maintained or configured; during the duration of the scheduling unit or symbol which is configured with transmission direction as uplink, the frequency domain bandwidth of the SBFD DL subband is reduced, or the SBFD DL subband is cancelled, or the SBFD DL subband and the SBFD UL subband are not configured and the scheduling unit or symbol configured with uplink is used for uplink transmission; during the duration of the scheduling unit or symbol which is configured with transmission direction as downlink, the frequency domain bandwidth of the SBFD UL subband is reduced, or the SBFD UL subband is cancelled, or the SBFD UL subband and the SBFD DL subband are not configured and the scheduling unit or symbol configured with downlink is used for downlink transmission.

[0077] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol which is not configured with transmission direction, the above-mentioned DL subband and UL subband are maintained, and the above-mentioned IBFD subband is maintained (if any). In some embodiments, in the case that the first information is used to configure SBFD subband, the SBFD DL subband and the SBFD UL subband can be configured during the duration of the scheduling unit or symbol which is not configured with transmission direction.

[0078] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol which is configured with transmission direction as DL, the above-mentioned UL subband is cancelled or the frequency domain bandwidth of the UL subband is reduced (relative to the originally configured frequency domain bandwidth). In some embodiments, in the case that the first information is used to configure SBFD subband, the SBFD DL subband and the SBFD UL subband can be not configured during the duration of the scheduling unit or symbol which is configured with transmission direction as DL and the scheduling unit or symbol configured with downlink is used for downlink transmission. For example, the frequency domain bandwidth of the UL subband after the bandwidth is reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced UL subband can be predefined, for example, starting from the boundary adjacent to the DL subband, i.e. the frequency domain resources adjacent to the DL subband in the UL subband are converted to the frequency domain resources of the DL subband.

[0079] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol in which the configured transmission direction is UL, the frequency domain bandwidth of the above-mentioned DL subband is cancelled, or the frequency domain bandwidth of the DL subband is reduced. In some embodiments, in the case that the first information is used to configure the SBFD subband, the SBFD DL subband and the SBFD UL subband can not be configured and the scheduling unit or symbol in the uplink can be used for uplink transmission during the duration of the scheduling unit or symbol in which the configured transmission direction is UL. For example, the frequency domain bandwidth of the DL subband after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc., and the position of the frequency domain bandwidth of the reduced DL subband can be predefined, for example, reduced from the boundary adjacent to the UL subband, that is, the frequency domain resource adjacent to the UL subband in the DL subband is converted to the frequency domain resource of the UL subband.

[0080] For the IBFD subband, during the duration of the scheduling unit or symbol in which the configured transmission direction is not UL, the IBFD subband is maintained or configured; during the duration of the scheduling unit or symbol in which the configured transmission direction is uplink, the frequency domain bandwidth of the IBFD subband is reduced, or the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband does not allow downlink transmission, or the IBFD subband is not configured and the scheduling unit or symbol in the uplink is used for UL transmission; during the duration of the scheduling unit or symbol in which the configured transmission direction is downlink, the frequency domain bandwidth of the IBFD subband is reduced, or the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband does not allow uplink transmission, or the IBFD subband is not configured and the scheduling unit or symbol in the downlink is used for downlink transmission.

[0081] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol in which the configured transmission direction is not UL, the above-mentioned DL subband (if any) and the UL subband (if any) are maintained, and the above-mentioned IBFD subband is maintained. In some embodiments, in the case that the first information is used to configure the IBFD subband, the IBFD subband can be configured during the duration of the scheduling unit or symbol in which the configured transmission direction is not UL.

[0082] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol configured with DL transmission direction, the frequency domain bandwidth of the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband is no longer allowed for UL transmission (i.e., for DL transmission), or the frequency domain bandwidth of the IBFD subband is reduced. In some embodiments, in the case that the first information is used to configure the IBFD subband, during the duration of the scheduling unit or symbol configured with DL transmission direction, the IBFD subband can be configured, or the IBFD subband is not configured and the scheduling unit (or symbol) of the downlink is used for downlink transmission. For example, the frequency domain bandwidth of the IBFD subband after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the IBFD subband after being reduced can be predefined, for example, reduced from the boundary of the low frequency end or the high frequency end.

[0083] Based on the first parameter to the fourth parameter, during the duration of the scheduling unit or symbol configured with UL transmission direction, the frequency domain bandwidth of the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband is no longer allowed for DL transmission (i.e., for UL transmission), or the frequency domain bandwidth of the IBFD subband is reduced. In some embodiments, in the case that the first information is used to configure the IBFD subband, during the duration of the scheduling unit or symbol configured with UL transmission direction, the IBFD subband can be configured, or the IBFD subband is not configured and the scheduling unit (or symbol) of the downlink is used for downlink transmission. For example, the frequency domain bandwidth of the IBFD subband after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the IBFD subband after being reduced can be predefined, for example, reduced from the boundary of the low frequency end or the high frequency end.

[0084] In an implementation, the first parameter to the fourth parameter can be represented by a third index value, i.e., the first parameter to the fourth parameter can be represented by an index value in a table or a set. For example, each row of the table corresponds to a set of values of the first parameter to the fourth parameter. The table has n rows. Then, an index value of a row is indicated by the DCI (e.g., the first information), so as to determine the values of the first parameter to the fourth parameter by the index value and the predefined table, thereby saving the field and reducing the signaling overhead.

[0085] From the above, the structure of the signaling of the above-mentioned manner one is the same as the frame structure signaling related to the 5G system, but the embodiments of the present disclosure re-interpret its meaning. If a carrier belonging to a band of the 5G system supports the 6G system (for example, only the band of the 5G system, but still wants to deploy the 6G system on the band), the signaling can be sent in the 6G system and as the frame structure signaling (for example, sent in the 6G system according to the signaling structure of the 5G system). In this way, the UE supporting only the 5G system can receive the signaling from the 6G system (the 6G system should support the backward compatibility of the 5G UE access) and understand it as the frame structure signaling. In this way, the 5G UE accessing the 6G system subsequently works according to the signaling. However, after the 6G UE receives the signaling, the signaling is parsed as the signaling of updating the above-mentioned three sub-bands.

[0086] Manner two

[0087] The first information includes at least one of the following: a fifth parameter, a sixth parameter, a seventh parameter, and an eighth parameter. The fifth parameter is used to indicate that one scheduling unit of the sub-band configuration period is the starting scheduling unit of the specified time domain resource. The sixth parameter is used to indicate that one scheduling unit of the sub-band configuration period is the ending scheduling unit of the specified time domain resource. The seventh parameter is used to indicate the starting symbol of the specified time domain resource in the starting scheduling unit. The eighth parameter is used to indicate the ending symbol of the specified time domain resource in the ending scheduling unit.

[0088] For the SBFD sub-band, within the specified time domain resource, the SBFD DL sub-band and the SBFD UL sub-band are maintained, or the SBFD DL sub-band and the SBFD UL sub-band are configured; during the duration of the first time domain resource located before the specified time domain resource in the sub-band configuration period, the frequency domain bandwidth of the SBFD UL sub-band is reduced, or the SBFD UL sub-band is cancelled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured and the first time domain resource is used for downlink transmission; during the duration of the second time domain resource located after the specified time domain resource in the sub-band configuration period, the frequency domain bandwidth of the SBFD DL sub-band is reduced, or the SBFD DL sub-band is cancelled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured and the second time domain resource is used for uplink transmission.

[0089] Based on the fifth parameter to the eighth parameter, the first node can obtain a set of scheduling units and symbols. The first node and the second node agree that during the duration of the obtained scheduling units and symbols, the above-mentioned DL sub-bandwidth and UL sub-band are maintained, and the above-mentioned IBFD sub-band is maintained (if any). In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the SBFD DL sub-band and the SBFD UL sub-band can be configured during the duration of the agreed obtained scheduling units and symbols.

[0090] Based on the fifth parameter to the eighth parameter, in one sub-band configuration period, and in the scheduling units and symbols before the indicated scheduling units and symbols (i.e., the first time domain resource), the above-mentioned UL sub-band is cancelled, or the frequency domain bandwidth of the UL sub-band is reduced (relative to the originally configured frequency domain bandwidth). In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the DL sub-band and the UL sub-band can not be configured and the first time domain resource can be used for downlink transmission during the duration of the first time domain resource. For example, the frequency domain bandwidth of the UL sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced UL sub-band can be predefined, for example, starting from the boundary adjacent to the DL sub-band, i.e., the frequency domain resource adjacent to the DL sub-band in the UL sub-band is converted to the frequency domain resource of the DL sub-band.

[0091] Based on the fifth parameter to the eighth parameter, in one sub-band configuration period, and in the scheduling units and symbols after the indicated scheduling units and symbols (i.e., the second time domain resource), the frequency domain bandwidth of the above-mentioned DL sub-band is cancelled, or the frequency domain bandwidth of the DL sub-band is reduced. In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the DL sub-band and the UL sub-band can not be configured and the second time domain resource can be used for uplink transmission during the duration of the second time domain resource. For example, the frequency domain bandwidth of the DL sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced DL sub-band can be predefined, for example, starting from the boundary adjacent to the UL sub-band, i.e., the frequency domain resource adjacent to the UL sub-band in the DL sub-band is converted to the frequency domain resource of the UL sub-band.

[0092] For the IBFD sub-band, the IBFD sub-band is maintained or configured within the specified time domain resource; during the duration of the first time domain resource before the specified time domain resource in the sub-band configuration period, the frequency domain bandwidth of the IBFD sub-band is reduced, or the IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band does not allow uplink transmission, or the IBFD sub-band is not configured and the first time domain resource is used for downlink transmission; during the duration of the second time domain resource after the specified time domain resource in the sub-band configuration period, the frequency domain bandwidth of the IBFD sub-band is reduced, or the IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band does not allow downlink transmission, or the IBFD sub-band is not configured and the second time domain resource is used for uplink transmission.

[0093] Based on the fifth parameter to the eighth parameter, a set of scheduling units and symbols can be obtained. The base station and the UE agree that the above-mentioned DL sub-bandwidth (if any) and UL sub-band (if any) are maintained, and the above-mentioned IBFD sub-band is maintained during the obtained scheduling unit and symbol duration. In some embodiments, in the case that the first information is used to configure the IBFD sub-band, the IBFD sub-band can be configured during the agreed obtained scheduling unit and symbol duration.

[0094] Based on the fifth parameter to the eighth parameter, in one sub-band configuration period, and in the scheduling units and symbols before the indicated scheduling units and symbols (i.e. the first time domain resource), the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed to be used for UL transmission (i.e. used for DL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case that the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the first time domain resource, and the first time domain resource is used for downlink transmission. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc., and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0095] Based on the fifth parameter to the eighth parameter, in one sub-band configuration period, and in the scheduling units and symbols after the indicated scheduling units and symbols (i.e. the second time domain resource), the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed to be used for DL transmission (i.e. used for UL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case that the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the second time domain resource, and the second time domain resource is used for uplink transmission. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc., and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0096] In an implementation manner, the above-mentioned fifth parameter to the eighth parameter can be represented by a third index value, that is, the fifth parameter to the eighth parameter can be represented by an index value in a table or a set. For example, each row of the table corresponds to a set of values of the fifth parameter to the eighth parameter. The table has n rows. Then, an index value of a row is indicated by the DCI (e.g. the first information), so as to determine the values of the fifth parameter to the eighth parameter by the index value and the predefined table, thereby saving the field and reducing the signaling overhead.

[0097] The third mode

[0098] The first information includes at least one of the following: a ninth parameter and a tenth parameter. The ninth parameter is used to indicate one symbol in the sub-band configuration period as the starting symbol of the specified time domain resource. The tenth parameter is used to indicate the number of symbols included in the specified time domain resource. In some embodiments, the ninth parameter can be one OFDM symbol in a period as the starting symbol, and the tenth parameter can be the number of consecutive symbols in the period starting from the time domain symbol indicated by the ninth parameter. In some embodiments, the ninth parameter and the tenth parameter can be jointly encoded as one parameter, for example, using a resource indication value (RIV) mechanism, thereby reducing signaling overhead.

[0099] For SBFD sub-band, during the duration of the time domain resource other than the specified time domain resource in the sub-band configuration period, the SBFD DL sub-band and the SBFD UL sub-band are maintained, or the SBFD DL sub-band and the SBFD UL sub-band are configured; during the duration of the specified time domain resource, the frequency domain bandwidth of the SBFD UL sub-band is reduced, or the SBFD UL sub-band is canceled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured and the specified time domain resource is used for downlink transmission; during the duration of the specified time domain resource, the frequency domain bandwidth of the SBFD DL sub-band is reduced, or the SBFD DL sub-band is canceled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured.

[0100] Based on the ninth parameter to the tenth parameter, a set of scheduling units and symbols (i.e. the specified time domain resource) can be obtained.

In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the DL sub-band and the UL sub-band can be configured during the duration of the obtained scheduling units and symbols.

[0101] Based on the ninth parameter to the tenth parameter, in a sub-band configuration period, and in the indicated symbol (i.e., the specified time domain resource), the above-mentioned UL sub-band is cancelled, or the frequency domain bandwidth of the UL sub-band is reduced (relative to the originally configured frequency domain bandwidth). In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the SBFD DL sub-band and the SBFD UL sub-band can not be configured and the specified time domain resource can be used for downlink transmission during the duration of the specified time domain resource. For example, the frequency domain bandwidth of the UL sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced UL sub-band can be predefined, for example, starting from the boundary adjacent to the DL sub-band, i.e., the frequency domain resource adjacent to the DL sub-band in the UL sub-band is converted to the frequency domain resource of the DL sub-band.

[0102] Based on the ninth parameter to the tenth parameter, in a sub-band configuration period, and in the indicated symbol (i.e., the specified time domain resource), the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed for DL transmission (i.e., for UL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the SBFD DL sub-band and the SBFD UL sub-band can not be configured during the duration of the specified time domain resource. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, starting from the boundary adjacent to the low frequency end or the high frequency end.

[0103] For the IBFD sub-band, during the duration of the time domain resource other than the specified time domain resource in the sub-band configuration period, the IBFD sub-band is maintained or configured; during the duration of the specified time domain resource, the frequency domain bandwidth of the IBFD sub-band is reduced, or the IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band does not allow uplink transmission, or the IBFD sub-band is not configured and the specified time domain resource is used for downlink transmission; during the duration of the specified time domain resource, the frequency domain bandwidth of the IBFD sub-band is reduced, or the IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band does not allow downlink transmission, or the IBFD sub-band is not configured.

[0104] Based on the ninth parameter to the tenth parameter, a set of scheduling units and symbols (i.e., specified time domain resources) can be obtained. The base station and the UE agree that the above-mentioned DL sub-bandwidth (if any) and UL sub-band (if any) and the above-mentioned IBFD sub-band are maintained during the duration of the obtained scheduling units and symbols (i.e., time domain resources other than the specified time domain resources in the sub-band configuration period). In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can be configured during the duration of the obtained scheduling units and symbols.

[0105] Based on the ninth parameter to the tenth parameter, in a sub-band configuration period, and in the indicated symbols, the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed for UL transmission (i.e., for DL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the specified time domain resources and the specified time domain resources are used for downlink transmission. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc., and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0106] Based on the ninth parameter to the tenth parameter, in a sub-band configuration period, and in the indicated symbols, the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed for DL transmission (i.e., for UL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the specified time domain resources. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc., and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0107] In an implementation, the above-mentioned ninth parameter to the tenth parameter can be represented by a third index value, i.e., the ninth parameter to the tenth parameter can be represented by an index value in a table or a set. For example, each row of the table corresponds to a set of values of the ninth parameter to the tenth parameter. The table has n rows. Then an index value of a row is indicated by the DCI (e.g., the first information), so that the value of the ninth parameter to the tenth parameter is determined by the index value and the predefined table, thereby saving the field and reducing the signaling overhead.

[0108] Method four

[0109] The first information includes at least one of the eleventh parameter and the twelfth parameter. The eleventh parameter is used to indicate the number of continuous symbols for downlink at the beginning of the sub-band configuration period; and the twelfth parameter is used to indicate the number of continuous symbols for uplink at the end of the sub-band configuration period. In some embodiments, the eleventh parameter can be the number of continuous DL symbols for downlink at the beginning of a period (by default, starting from the first symbol of the period), and the twelfth parameter can be the number of continuous UL symbols for uplink at the end of a period (by default, ending at the last symbol of the period).

[0110] For SBFD sub-band, during the duration of a scheduling unit or symbol whose transmission direction is not configured, the SBFD DL sub-band and the SBFD UL sub-band are maintained, or the SBFD DL sub-band and the SBFD UL sub-band are configured; during the duration of a scheduling unit or symbol whose transmission direction is configured as uplink, the frequency domain bandwidth of the SBFD DL sub-band is reduced, or the SBFD DL sub-band is cancelled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured and the scheduling unit or symbol in uplink is used for uplink transmission; during the duration of a scheduling unit or symbol whose transmission direction is configured as downlink, the frequency domain bandwidth of the SBFD UL sub-band is reduced, or the SBFD UL sub-band is cancelled, or the SBFD DL sub-band and the SBFD UL sub-band are not configured and the scheduling unit or symbol in downlink is used for downlink transmission.

[0111] Based on the eleventh parameter to the twelfth parameter, during the duration of a symbol whose transmission direction is not configured (i.e., time domain resources in a period other than the time domain resources indicated by the eleventh parameter and the twelfth parameter), the above-mentioned DL sub-bandwidth and UL sub-band are maintained, and the above-mentioned IBFD sub-band is maintained (if any). In some embodiments, in the case where the first information is used to configure the SBFD sub-band, the SBFD DL sub-band and the SBFD UL sub-band can be configured during the duration of a symbol whose transmission direction is not configured.

[0112] Based on the eleventh parameter to the twelfth parameter, during the duration of the symbol configured with DL transmission direction, the UL subband is cancelled or the frequency domain bandwidth of the UL subband is reduced (relative to the originally configured frequency domain bandwidth). In some embodiments, in the case that the first information is used to configure SBFD subband, the SBFD DL subband and the SBFD UL subband can not be configured during the duration of the symbol configured with DL transmission direction and the scheduling unit or symbol of the downlink is used for downlink transmission. For example, the frequency domain bandwidth of the UL subband after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced UL subband can be predefined, for example, starting from the boundary adjacent to the DL subband, i.e. the frequency domain resources adjacent to the DL subband in the UL subband are converted to the frequency domain resources of the DL subband.

[0113] Based on the eleventh parameter to the twelfth parameter, during the duration of the symbol configured with UL transmission direction, the frequency domain bandwidth of the DL subband is cancelled or the frequency domain bandwidth of the DL subband is reduced. In some embodiments, in the case that the first information is used to configure SBFD subband, the SBFD DL subband and the SBFD UL subband can not be configured during the duration of the symbol configured with UL transmission direction and the scheduling unit or symbol of the uplink is used for uplink transmission. For example, the frequency domain bandwidth of the DL subband after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced DL subband can be predefined, for example, starting from the boundary adjacent to the UL subband, i.e. the frequency domain resources adjacent to the UL subband in the DL subband are converted to the frequency domain resources of the UL subband.

[0114] For the IBFD subband, during the duration of the scheduling unit or symbol without configured transmission direction, the IBFD subband is maintained or configured; during the duration of the scheduling unit or symbol configured with uplink transmission direction, the frequency domain bandwidth of the IBFD subband is reduced, or the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband does not allow downlink transmission, or the IBFD subband is not configured and the scheduling unit or symbol of the uplink is used for uplink transmission; during the duration of the scheduling unit or symbol configured with downlink transmission direction, the frequency domain bandwidth of the IBFD subband is reduced, or the IBFD subband is cancelled, or the frequency domain bandwidth of the IBFD subband does not allow uplink transmission, or the IBFD subband is not configured and the scheduling unit or symbol of the uplink is used for uplink transmission.

[0115] Based on the eleventh parameter to the twelfth parameter, during the duration of the symbol in which the transmission direction is not configured, the above-mentioned DL sub-bandwidth (if any) and UL sub-band are maintained (if any), and the above-mentioned IBFD sub-band is maintained. In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can be configured during the duration of the symbol in which the transmission direction is not configured.

[0116] Based on the eleventh parameter to the twelfth parameter, during the duration of the symbol in which the configured transmission direction is DL, the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed for UL transmission (i.e., for DL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the symbol in which the configured transmission direction is DL, and the scheduling unit or symbol of the downlink is used for downlink transmission. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0117] Based on the eleventh parameter to the twelfth parameter, during the duration of the symbol in which the configured transmission direction is UL, the frequency domain bandwidth of the above-mentioned IBFD sub-band is cancelled, or the frequency domain bandwidth of the IBFD sub-band is no longer allowed for DL transmission (i.e., for UL transmission), or the frequency domain bandwidth of the IBFD sub-band is reduced. In some embodiments, in the case where the first information is used to configure the IBFD sub-band, the IBFD sub-band can not be configured during the duration of the symbol in which the configured transmission direction is UL, and the scheduling unit or symbol of the uplink is used for uplink transmission. For example, the frequency domain bandwidth of the IBFD sub-band after being reduced can be predefined, for example, reduced to 1 / 2, 1 / 4, etc. of the original, and the position of the frequency domain bandwidth of the reduced IBFD sub-band can be predefined, for example, reduced from the boundary with the low frequency end or the high frequency end.

[0118] In an implementation manner, the above-mentioned eleventh parameter to the twelfth parameter can be represented by a third index value, that is, the eleventh parameter to the twelfth parameter can be represented by an index value in a table or a set. For example, each row of the table corresponds to a set of values of the eleventh parameter to the twelfth parameter. The table has n rows. Then, an index value of a row is indicated by the DCI (for example, the first information), so as to determine the values of the eleventh parameter to the twelfth parameter by the index value and the predefined table, thereby saving the field and reducing the signaling overhead.

[0119] In the following, the above manners will be introduced in combination with multiple examples. For example, for the first manner, the following will be described in combination with example one to example three.

[0120] Example one

[0121] FIG. 7 shows a schematic diagram of a subband. As shown in FIG. 7, the UL subband is configured with a part of frequency domain bandwidth, in which the non-overlapping frequency domain bandwidth is the frequency domain bandwidth for SBFD uplink transmission, i.e., the UL subband. The DL subband is similar. The frequency domain bandwidth of the DL subband overlapping with the UL subband is the IBFD subband. The second node configures slot0 and slot1 as downlink slots, slot8 and slot9 as uplink slots, and slot 2-slot 7 as unindicated slots according to the first information in the first manner. If the first node and the second node agree that the signaling (i.e., the first information) for adjusting the subband configuration is used to perform the above-mentioned H, i.e., at least one of the three configured subbands (i.e., the SBFD DL subband, the SBFD UL subband, and the IBFD subband) is canceled and the remaining subband (i.e., the subband not canceled) uses the transmission direction indicated by the signaling (e.g., the first information).

[0122] In this case, the first node and the second node determine that, in slot0 and slot1 configured as downlink transmission directions, at least one of the configured subbands is canceled, and slot0 and slot1 subsequently use the downlink transmission direction indicated by the first information, i.e., slot0 and slot1 are used for downlink transmission. In slot8 and slot9 indicated as uplink transmission directions, at least one of the configured subbands is canceled, and slot8 and slot9 subsequently use the uplink transmission direction indicated by the first information.

[0123] Example two

[0124] FIG. 8 shows a schematic diagram of another subband. As shown in FIG. 8, the UL subband is configured with a part of frequency domain bandwidth, in which the non-overlapping frequency domain bandwidth is the frequency domain bandwidth for SBFD uplink transmission. The DL subband is similar. The frequency domain bandwidth of the DL subband overlapping with the UL subband is the IBFD subband. The second node configures slot0 and slot1 as downlink slots, slot8 and slot9 as uplink slots, and slot 2-slot 7 as unindicated slots according to the first information in the first manner. If the first node and the second node agree that the signaling (i.e., the first information) for adjusting the subband configuration is used to perform the above-mentioned K, i.e., the IBFD subband is canceled, and the canceled IBFD subband is used for the DL subband and the UL subband.

[0125] In this case, the first node and the second node can determine that, in the slots 0 and 1 which are configured as downlink transmission direction, the IBFD subbands are cancelled. The frequency domain resources of the original IBFD subbands are agreed to be used for downlink transmission, which actually expands the effective frequency domain resources of the DL subband. That is, the resources of the IBFD subbands cancelled in the slots 0 and 1 are used to expand the effective frequency domain resources of the DL subband. In the slots 8 and 9 which are indicated as uplink transmission direction, the IBFD subbands are cancelled. That is, the effective frequency domain resources of the uplink subband in the slots 8 and 9 are expanded, i.e. the resources of the IBFD subbands cancelled in the slots 8 and 9 are used to expand the effective frequency domain resources of the UL subband. The subband configuration in the slots 2-7 remains unchanged.

[0126] Example Three

[0127] Figure 9 shows another schematic diagram of subbands. As shown in Figure 9, the UL subband and the DL subband are respectively configured with a part of frequency domain bandwidth, and the DL subband has no overlapping frequency domain resources with the UL subband, i.e. there is no IBFD subband. As shown in Figure 10, the first node can update the UL subband and the DL subband according to the first information of the first mode, so that the slots 0 and 1 are configured as DL slots, the slots 8 and 9 are configured as UL slots, and the slots 2-7 are configured as unconfigured slots. If the first node and the second node agree that the signaling (i.e. the first information) for adjusting the subband configuration is used to perform any one of the above A, B, C and D.

[0128] In this case, the first node and the second node can determine that, in the slots 0 and 1 which are configured as downlink transmission direction, the DL subband is expanded to 1.5 times of the original (the multiple can be defined, for example, multiple relationships are defined based on a table, and the bandwidth size used this time is determined by agreement or signaling), and the expanded frequency domain resources come from the UL subband. Alternatively, in the slots 0 and 1 which are configured as downlink transmission direction, the UL subband is reduced to 0.5 times of the original, and the reduced frequency domain resources are used for the DL subband. In the slots 8 and 9 which are indicated as uplink transmission direction, the UL subband is expanded to 1.5 times of the original, and the expanded frequency domain resources come from the DL subband. Alternatively, in the slots 8 and 9 which are indicated as uplink transmission direction, the DL subband is reduced to 0.5 times of the original, and the reduced frequency domain resources are used for the UL subband, and the subband configuration in the slots 2-7 remains unchanged.

[0129] Mode Five

[0130] The first information includes a first index value, the first index value is associated with an index of a frame structure and a subband configuration of the SBFD subband or the IBFD subband; or the first index value is an index of a frame structure, and different frame structures are associated with different subband configurations of the SBFD subband or the IBFD subband.

[0131] It should be noted that, in the case where the first information is used to configure the subband configuration, the subband configuration associated with the first index value is the subband configuration that needs to be configured; in the case where the first information is used to update the subband configuration, the subband configuration associated with the first index value is the subband configuration that needs to be updated.

[0132] The frame structure can be associated with the subband configuration. One frame structure corresponds to one preconfigured subband configuration (i.e., at least one of the UL subband, the DL subband, and the IBFD subband). In this way, the first information can include a first index value, the index value is associated with an index of a frame structure and a subband configuration. Or the first index value is an index of a frame structure, and based on the index of the frame structure and the corresponding relationship of the pre-association, the subband configuration corresponding to the index of the frame structure can be determined.

[0133] In an implementation manner, the subband configuration includes at least one of the following: a frequency domain parameter of the SBFD UL subband, a transmission parameter of the SBFD UL subband, a frequency domain parameter of the SBFD DL subband, a transmission parameter of the SBFD DL subband, a frequency domain parameter of the IBFD subband, and a transmission parameter of the IBFD subband.

[0134] Exemplarily, Tables 1 to 4 show a schematic table of the corresponding relationship between four frame structures and subband configurations. As shown in Table 1, one first index value corresponds to one frame structure index and one set of subband configurations, the set of subband configurations includes frequency domain parameters of three types of subbands, and transmission parameters corresponding to the subbands. As shown in Table 2, one first index value corresponds to one frame structure index and one set of subband configurations, the set of subband configurations includes frequency domain parameters of the UL subband, and transmission parameters corresponding to the UL subband. As shown in Table 3, one first index value corresponds to one frame structure index and one set of subband configurations, the set of subband configurations includes frequency domain parameters of the DL subband, and transmission parameters corresponding to the DL subband.

[0135] In addition, the subband configurations in Tables 1 and 2 are valid in all (or part) slots in the associated frame structure, for example, at least one of the following: valid only in DL slots, valid only in flexible slots, valid only in slots where DL & UL symbols are located, valid only in UL slots, and valid only in slots indicated by signaling.

[0139] Table 4

[0140] Mode six

[0141] The first information includes a second index value, and the second index value is associated with time domain resources and / or frequency domain resources of the subband.

[0142] It should be noted that the time domain resources and / or frequency domain resources associated with the second index value are resources used by the first information to configure or update the subband configuration.

[0143] The first node can configure a set or a table, and an element in the set (or a row in the table) includes time domain resources and / or frequency domain resources of at least one subband. The first node can represent an element in the set (or a row in the table) by the second index value, thereby saving fields and reducing signaling overhead.

[0144] The frequency domain resources of the subband include at least one of: a frequency domain size of the subband (for example, in RBs), a frequency domain position of the subband (for example, an indexed RB, the index describes the position of the RB in the carrier, so the frequency domain position of the subband can be obtained), a subband bandwidth scaling factor (for example, the original subband bandwidth multiplied by the factor to obtain a new subband bandwidth). The center of the new subband remains the same as the original subband.

[0145] The time domain resources of the subband include at least one of: a starting slot of the subband, a slot number of the subband (or a last slot of the subband), a starting symbol in the starting slot of the subband, an ending symbol in the last slot of the subband.

[0146] In an implementation manner, the first information includes at least one of: a frequency domain position of the target subband, a frequency domain size of the target subband. The target subband is an SBFD subband or an IBFD subband.

[0147] The first node can send signaling (e.g., the first information) through DCI, MAC CE (medium access control control elements), RRC, etc. The signaling can represent an index for a corresponding element in a set or a row in a table. After receiving the signaling through DCI, MAC CE, RRC, etc., the second node can determine an element from the set according to the signaling, and configure or update a subband based on the subband configuration corresponding to the element. Or, determine a row of elements from the table according to the signaling, and configure or update a subband based on the subband configuration in the column associated with the row of elements. In some embodiments, the frequency domain location and size of the subband can also be configured as a table. Table 5 shows a table of frequency domain location and size of a subband. As shown in Table 5, the frequency domain start RB of the subband is the frequency domain location of the subband (including the frequency domain start RB of the subband, i.e., the RB index), and the frequency domain size of the subband includes the number of RBs. The first node can indicate a row index through DCI signaling, so as to obtain the configuration information of the corresponding subband frequency domain, such as the frequency domain location and the frequency domain size of the subband, based on the table. The DL subband, the UL subband, and the IBFD subband can be configured with frequency domain resources based on the table respectively.

[0148] Table 5

[0149] It should be noted that the frequency domain location and the frequency domain size of the subband can be combined with the configuration of the time domain resource in the above-mentioned mode 1 to mode 4. For example, the first information is configured based on a set or a table. One set contains one or more elements, and one element in the set or one row in the table is associated with at least one of the following first parameter group to sixth parameter group.

[0150] The first parameter group at least contains one of the following: the first parameter, the second parameter, the third parameter, the fourth parameter, the frequency domain location of the SBFD subband or the IBFD subband, and the frequency domain size of the SBFD subband or the IBFD subband.

[0151] The second parameter group at least contains one of the following: the fifth parameter, the sixth parameter, the seventh parameter, the eighth parameter, the frequency domain location of the SBFD subband or the IBFD subband, and the frequency domain size of the SBFD subband or the IBFD subband.

[0152] The third parameter group at least contains one of the following: the ninth parameter, the tenth parameter, the frequency domain location of the SBFD subband or the IBFD subband, and the frequency domain size of the SBFD subband or the IBFD subband.

[0153] The fourth parameter group at least contains one of the following: the eleventh parameter, the twelfth parameter, the frequency domain location of the SBFD subband or the IBFD subband, and the frequency domain size of the SBFD subband or the IBFD subband.

[0154] The fifth parameter group comprises at least one of the following: the thirteenth parameter, the fourteenth parameter, the fifteenth parameter, the sixteenth parameter, a frequency domain position of the SBFD subband or the IBFD subband, and a frequency domain size of the SBFD subband or the IBFD subband.

[0155] The sixth parameter group comprises at least one of the following: the seventeenth parameter, the eighteenth parameter, a frequency domain position of the SBFD subband or the IBFD subband, and a frequency domain size of the SBFD subband or the IBFD subband.

[0156] The frequency domain position of the SBFD subband or the IBFD subband is configured based on a resource block index, and the frequency domain size of the SBFD subband or the IBFD subband is configured based on a resource block quantity.

[0157] The first parameter group corresponds to a first mode of including a frequency domain position and a frequency domain size, the second parameter group corresponds to a second mode of including the frequency domain position and the frequency domain size, the third parameter group corresponds to a third mode of including the frequency domain position and the frequency domain size, the fourth parameter group corresponds to a fourth mode of including the frequency domain position and the frequency domain size, the fifth parameter group corresponds to a seventh mode of including the frequency domain position and the frequency domain size, and the sixth parameter group corresponds to an eighth mode of including the frequency domain position and the frequency domain size.

[0158] In order to further reduce signaling overhead, the following seventh and eighth modes can be considered to simplify the first to fourth modes. For example, the parameters in the first to fourth modes are associated with one element or one row.

[0159] The seventh mode

[0160] The first information comprises at least one of the following: the thirteenth parameter, the fourteenth parameter, the fifteenth parameter, and the sixteenth parameter. The thirteenth parameter is used to indicate a starting slot of a target subband. The fourteenth parameter is used to indicate a starting symbol of the target subband in the starting slot. The fifteenth parameter is used to indicate an ending slot of the target subband. The sixteenth parameter is used to indicate an ending symbol of the target subband in the ending slot. The target subband is an SBFD subband or an IBFD subband. For example, the thirteenth parameter is used to describe a starting slot of an SBFD / IBFD subband. The fourteenth parameter is used to describe a starting symbol of the SBFD / IBFD subband in the starting slot. The fifteenth parameter is used to describe an ending slot of the SBFD / IBFD subband. The sixteenth parameter is used to describe an ending symbol of the SBFD / IBFD subband in the ending slot. The time domain position of the subband can be configured through the parameters.

[0161] If one SBFD / IBFD period is equal to one frame period, and the subcarrier spacing of the carrier is 15 KHz, then one SBFD / IBFD period contains 10 slots, and each slot contains 14 symbols. The signaling overhead of the above signaling is: the thirteenth parameter and the fifteenth parameter each need 4 bits, the fourteenth parameter and the sixteenth parameter each need 4 bits. Thus, the signaling overhead is 16 bits. In some embodiments, the first node and the second node can agree that at least one of the above four parameters can be in the form of an agreed value, thereby reducing the signaling overhead.

[0162] Mode eight

[0163] The first information includes at least one of the following: a seventeenth parameter, an eighteenth parameter. The seventeenth parameter is used to indicate the starting symbol of the target subband. The eighteenth parameter is used to indicate the ending symbol of the target subband. The target subband is an SBFD subband or an IBFD subband. The time domain position of the subband can be configured through the parameter. In some embodiments, the seventeenth parameter is used to describe the starting symbol of one SBFD / IBFD subband. The eighteenth parameter is used to describe the number of consecutive symbols or to describe the ending symbol of the SBFD / IBFD subband. The corresponding signaling overhead is: the seventeenth parameter and the eighteenth parameter each need 8 bits. Thus, the signaling overhead is 16 bits.

[0164] In some embodiments, the first node and the second node can agree that at least one of the above two parameters can be in the form of an agreed value, thereby reducing the signaling overhead.

[0165] In an implementation mode, in order to reduce the signaling overhead, the following design 1 and design 2 can be used for the above mode seven and mode eight.

[0166] Design 1

[0167] The first node configures a set associated with the SBFD / IBFD subband through signaling, and configures associated parameters for the elements in the set. For example, element 0 is configured to be associated with the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter, and a corresponding value is configured for each parameter. Element 1 is configured to be associated with the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter, and a corresponding value is configured for each parameter. Element 2 is configured to be associated with the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter, and a corresponding value is configured for each parameter. The SBFD / IBFD subband in the indicated slot and symbol is configured or maintained. The SBFD / IBFD subband (if any) in the unindicated slot and symbol is cancelled or reduced in frequency domain resource.

[0168] The values of the associated parameters of each element can be determined according to historical experience of uplink and downlink load changes of the first node, so that the values of the associated parameters of the elements are consistent with the uplink and downlink load changes in most cases.

[0169] The number of elements in the set can be predefined or configured by signaling. A parameter in the DCI is used to indicate that the index of the element comes from the set. For example, the number of elements in the set can be configured as 64, 128, etc., thereby reducing the signaling overhead. In this way, the first node can configure the values of the associated parameters of the elements, thereby meeting the needs of uplink and downlink load changes, and indicating the elements through the parameter in the DCI to dynamically update the configuration of the SBFD / IBFD subband in the time domain.

[0170] Further, considering that the SBFD / IBFD subband can also be updated in the frequency domain, for example, the frequency domain size and position can be updated. Therefore, the elements in the above set can also be configured to associate the frequency domain position and / or size of the SBFD / IBFD subband. The frequency domain position and size of the SBFD / IBFD subband are described based on RB index and number respectively, or the frequency domain size of the SBFD / IBFD subband can be described by a coefficient, for example, the original frequency domain resource multiplied by the coefficient to obtain the frequency domain size of the new SBFD / IBFD subband. The position can be agreed to be scalable from a certain side.

[0171] Design 2

[0172] The base station configures a table associated with the SBFD / IBFD subband by signaling, and configures associated parameters for each row in the table. For example, row 0 is configured to associate the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter described above, and a corresponding value is configured for each parameter. Row 1 is configured to associate the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter described above, and a corresponding value is configured for each parameter. Element 2 is configured to associate the thirteenth parameter, the fourteenth parameter, the fifteenth parameter and the sixteenth parameter described above, and a corresponding value is configured for each parameter. The SBFD / IBFD subband in the indicated slot and symbol is configured or maintained. The SBFD / IBFD subband (if any) in the unindicated slot and symbol is cancelled or reduced in frequency domain resource.

[0173] The values of the associated parameters of each row can be determined according to historical experience of uplink and downlink load changes of the base station, so that the values of the associated parameters of each row are consistent with the uplink and downlink load changes in most cases.

[0174] The number of rows included in the table can be predefined or configured through signaling. A parameter in the DCI indicates the row index from the table. For example, the number of rows in the table can be configured as 64, 128, and the like, thereby reducing the signaling overhead. In this way, the first node can configure the value of the associated parameters of the row, thereby meeting the demand of the change of uplink and downlink load. And through the parameter in the DCI, the row index is indicated, thereby realizing dynamic updating of the configuration of the SBFD / IBFD subband in the time domain.

[0175] Further, considering that the SBFD / IBFD subband can also be updated in the frequency domain, for example, the frequency domain size and position can be updated. Therefore, a row in the above table can also be configured to associate the frequency domain position and / or size of the SBFD / IBFD subband. The frequency domain position and size of the SBFD / IBFD subband are described based on RB index and quantity, respectively, or the frequency domain size of the SBFD / IBFD subband can be described by a coefficient, for example, the original frequency domain resource is multiplied by a coefficient to obtain the frequency domain size of the new SBFD / IBFD subband. The position can be agreed to be scalable from a certain side. Obviously, the above method can also be used to directly configure a SBFD / IBFD subband.

[0176] The subband configuration updating method provided by the embodiments of the present disclosure can be applied to the second node 402 in the communication system shown in FIG. 4. FIG. 11 shows a flow diagram of another subband configuration updating method. As shown in FIG. 11, the subband configuration updating method includes S1101.

[0177] In S1101, the first information is received.

[0178] The first information is used to configure / update the configuration of the subband in the first frequency domain resource. The subband includes SBFD subband and / or IBFD subband.

[0179] After configuring the subband configuration, the first node can send the first information to the second node. After receiving the first information, the second node can reconfigure or update the subband based on the first information.

[0180] The second node receives the first information (the first information is used to configure the subband), and obtains the IBFD subband based on the configured SBFD subband. In this way, the subband configuration of the first node and the subband configuration of the second node can be synchronized, thereby enabling transmission through the subband, thereby solving the problem of how to configure or update the subband.

[0181] In the embodiments of the present disclosure, the response or understanding of the second node to the first information can refer to the description of the first node side or be modified adaptively (if necessary, for example, from sending to receiving), which will not be described here again.

[0182] It can be understood that, in order to achieve the above functions, the sub-band configuration updating apparatus comprises hardware structures and / or software modules corresponding to the functions. Those skilled in the art should easily understand that, in combination with the algorithm steps of the examples described in the embodiments of the present disclosure, the present disclosure can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is realized in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the present disclosure.

[0183] The embodiments of the present disclosure can divide the function modules of the sub-band configuration updating apparatus according to the above-mentioned method embodiments. For example, each function module can be divided according to each function, or two or more functions can be integrated into one function module. The integrated module can be realized in the form of hardware or software. It should be noted that the division of the modules in the embodiments of the present disclosure is illustrative, and is only a logical function division. In actual implementation, another division method can be used. Hereinafter, taking the division of each function module according to each function as an example for description.
