[0048] The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the description of the embodiments of the present application and the claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0049] It should be understood that although the terms first, second, third, etc. can be used herein to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present application, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. In addition, depending on the context, the word "if" used herein can be interpreted as "when" or "upon" or "in response to determining".

[0050] The TDD system can work in the HD mode, that is, the same frequency domain resource can be used for UL or DL at the same time. In order to use the frequency domain resource more flexibly and improve the resource utilization, the TDD system can also work in the FD (Full-Duplex) mode. That is, the same frequency domain resource is used for UL and DL at the same time, that is, the uplink data and the downlink data are processed on the same frequency domain resource at the same time.

[0051] In the TDD system, the frame structure is divided into DL slots, UL slots and flexible slots (F slots). The DL slot includes a plurality of DL symbols, and the downlink data is processed on the frequency domain resource corresponding to the DL symbols. The UL slot includes a plurality of UL symbols, and the uplink data is processed on the frequency domain resource corresponding to the UL symbols. The F slot includes at least one F symbol, and the F symbol can be used for DL, UL or GP.

[0052] In the TDD system, once the frame structure is determined, the UE can perform data transmission and reception according to the frame structure. For the UE in the HD (Half Duplex) mode, the base station (such as gNB, etc.) schedules the UE to transmit or receive according to the frame structure. For the UE in the FD mode, the base station schedules the transmission, reception or simultaneous transmission and reception of the UE according to the frame structure. In summary, the base station can configure the frame structure and notify the UE of the frame structure, so that the UE knows the frame structure and correctly performs data transmission and reception.

[0053] From another angle, after the UE knows the frame structure, it can also know the possible inter-UE interference, so as to use the interference cancellation technology to reduce the interference and improve the communication reliability.

[0054] In one example, for the uplink-oriented frame structure, more UL slots are usually configured, which results in fewer DL slots, limits the downlink transmission rate, and increases the transmission delay of downlink data. The larger downlink transmission delay also does not take advantage of downlink services. For the downlink-oriented frame structure, more DL slots are usually configured, which results in fewer UL slots, limits the uplink transmission rate, and increases the transmission delay of uplink data. The larger uplink transmission delay also does not take advantage of uplink services.

[0055] The present application proposes a resource allocation method. In the method, flexible BWP configuration is used in multi-carrier, and flexible SBFD frequency domain resources (such as downlink sub-band resources and uplink sub-band resources) are configured for UEs in the BWP. For example, uplink sub-band resources can be configured in downlink slots or flexible slots, and uplink data is transmitted in the uplink sub-band resources. In this way, uplink data is transmitted in downlink slots or flexible slots, the uplink transmission rate is improved, and the transmission delay of uplink data is reduced. In addition, downlink sub-band resources can be configured in uplink slots or flexible slots, and downlink data is transmitted in the downlink sub-band resources. In this way, downlink data is transmitted in uplink slots or flexible slots, the downlink transmission rate is improved, and the transmission delay of downlink data is reduced.

[0056] In one example of the present application, a resource allocation method is proposed. The method can be applied to a base station. Referring to FIG. 1, a flowchart of the resource allocation method is shown. The method can include the following steps. Figure 1A

[0057] In step 111, BWP frequency domain resource configuration information is sent to the UE. The BWP frequency domain resource configuration information can include a mapping relationship between resource identifiers and SBFD frequency domain resources. The resource identifiers can include BWP identifiers and carrier identifiers, that is, the BWP frequency domain resource configuration information can include a mapping relationship between BWP identifiers, carrier identifiers, and SBFD frequency domain resources.

[0058] In step 112, target BWP indication information is sent to the UE. The target BWP indication information is used to make the UE obtain a target BWP configuration pair corresponding to the target BWP indication information from a BWP activation configuration table. The target BWP configuration pair can include a target BWP identifier and a target carrier identifier. Based on the mapping relationship between the resource identifiers and the SBFD frequency domain resources, the target SBFD frequency domain resources associated with the target BWP identifier and the target carrier identifier are determined. The BWP activation configuration table can include a mapping relationship between BWP indication information and BWP configuration pairs.

[0059] In one example of the present application, a resource allocation method is proposed. The method can be applied to a UE. Referring to FIG. 2, a flowchart of the resource allocation method is shown. The method can include the following steps. Figure 1B ​As shown, a flowchart of the resource allocation method is shown. The method can include the following steps:

[0060] In step 121, BWP frequency domain resource configuration information sent by the base station is received. The BWP frequency domain resource configuration information includes a mapping relationship between a resource identifier and an SBFD frequency domain resource. The resource identifier can include a BWP identifier and a carrier identifier, i.e., the BWP frequency domain resource configuration information can include a mapping relationship between a BWP identifier and an SBFD frequency domain resource.

[0061] In step 122, target BWP indication information sent by the base station is received, and a target BWP configuration pair corresponding to the target BWP indication information is obtained from the acquired BWP activation configuration table. The target BWP configuration pair can include a target BWP identifier and a target carrier identifier. The BWP activation configuration table can include a mapping relationship between BWP indication information and a BWP configuration pair.

[0062] In step 123, based on the mapping relationship between the resource identifier and the SBFD frequency domain resource, the target SBFD frequency domain resource associated with the target BWP identifier and the target carrier identifier in the target BWP configuration pair is determined.

[0063] In one example, for the BWP identifier and the carrier identifier in the BWP frequency domain resource configuration information, the BWP identifier includes an uplink BWP identifier and a downlink BWP identifier, the uplink BWP identifier is the same as the downlink BWP identifier, and the carrier identifier includes a first carrier identifier and a second carrier identifier. The uplink BWP identifier corresponds to the first carrier identifier, and the downlink BWP identifier corresponds to the second carrier identifier. Alternatively, the uplink BWP identifier corresponds to the first carrier identifier, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier. Alternatively, the downlink BWP identifier corresponds to the first carrier identifier, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier. Alternatively, the uplink BWP identifier and the downlink BWP identifier correspond to the first carrier identifier, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier.

[0064] In one example, for the BWP identifier and the carrier identifier in the BWP frequency domain resource configuration information, the BWP identifier includes an uplink BWP identifier and a downlink BWP identifier, the uplink BWP identifier is different from the downlink BWP identifier. The carrier identifier includes a first carrier identifier and a second carrier identifier, the uplink BWP identifier corresponds to the first carrier identifier, and the downlink BWP identifier corresponds to the second carrier identifier. Alternatively, the BWP identifier includes a first uplink BWP identifier, a first downlink BWP identifier, a second uplink BWP identifier, and a second downlink BWP identifier, the first uplink BWP identifier is the same as the first downlink BWP identifier, the second uplink BWP identifier is the same as the second downlink BWP identifier, the first uplink BWP identifier is different from the second uplink BWP identifier, and the first downlink BWP identifier is different from the second downlink BWP identifier. The carrier identifier includes a first carrier identifier and a second carrier identifier, the first uplink BWP identifier and the first downlink BWP identifier correspond to the first carrier identifier, and the second uplink BWP identifier and the second downlink BWP identifier correspond to the second carrier identifier.

[0065] In one example, the SBFD frequency domain resource is a frequency domain resource configured in a carrier indicated by the carrier identifier, and the SBFD frequency domain resource is a frequency domain resource corresponding to the BWP identifier. The SBFD frequency domain resource corresponding to the uplink BWP identifier is different from the SBFD frequency domain resource corresponding to the downlink BWP identifier, and the size of the SBFD frequency domain resource corresponding to the uplink BWP identifier is the same as or different from the size of the SBFD frequency domain resource corresponding to the downlink BWP identifier. The carriers indicated by different carrier identifiers are SBFD intra-subband carriers or SBFD inter-subband carriers.

[0066] In one example, the base station can also send the BWP activation configuration table to the UE through an RRC (Radio Resource Control) message, and the UE receives the BWP activation configuration table sent by the base station through the RRC message. Alternatively, the BWP activation configuration table pre-configured in the UE through the physical layer can also be obtained by the UE.

[0067] In one example, each BWP configuration pair in the BWP activation configuration table can include a downlink BWP identifier and a carrier identifier corresponding to the downlink BWP identifier, an uplink BWP identifier and a carrier identifier corresponding to the uplink BWP identifier. Among them, the target BWP configuration pair can include a target downlink BWP identifier and a target uplink BWP identifier, and the target downlink BWP identifier is the same as or different from the target uplink BWP identifier.

[0068] In addition, the target BWP configuration pair can include a carrier identifier corresponding to a target downlink BWP identifier and a carrier identifier corresponding to a target uplink BWP identifier, and the carrier identifier corresponding to the target downlink BWP identifier can be the same as or different from the carrier identifier corresponding to the target uplink BWP identifier.

[0069] In one example, each BWP configuration pair in the BWP activation configuration table can include a first configuration sub-pair and a second configuration sub-pair. The first configuration sub-pair can include a first downlink BWP identifier and a carrier identifier corresponding to the first downlink BWP identifier, a first uplink BWP identifier and a carrier identifier corresponding to the first uplink BWP identifier. The second configuration sub-pair can include a second downlink BWP identifier and a carrier identifier corresponding to the second downlink BWP identifier, a second uplink BWP identifier and a carrier identifier corresponding to the second uplink BWP identifier.

[0070] The target BWP configuration pair can include a target first configuration sub-pair and a target second configuration sub-pair.

[0071] The target first configuration sub-pair can include a target first downlink BWP identifier and a target first uplink BWP identifier, which can be the same or different. The target first configuration sub-pair can include a carrier identifier corresponding to the target first downlink BWP identifier and a carrier identifier corresponding to the target first uplink BWP identifier, which can be the same or different.

[0072] The target second configuration sub-pair can include a target second downlink BWP identifier and a target second uplink BWP identifier, which can be the same or different. The target second configuration sub-pair can include a carrier identifier corresponding to the target second downlink BWP identifier and a carrier identifier corresponding to the target second uplink BWP identifier, which can be the same or different.

[0073] In one example, the base station can send the BWP activation configuration to the UE through a DCI message (Downlink Control Information), and the UE receives the BWP activation configuration sent by the base station through the DCI message. Alternatively, the base station sends the BWP activation configuration to the UE through a MAC-CE (MAC Control Element) message, and the UE receives the BWP activation configuration sent by the base station through the MAC-CE message. Alternatively, the base station sends the BWP activation configuration to the UE through an RRC message, and the UE receives the BWP activation configuration sent by the base station through the RRC message. Of course, the above are only a few examples, and this is not limited.

[0074] The BWP activation configuration can include target BWP indication information and a switch flag. If the switch flag is a first value, the UE obtains a target BWP configuration pair corresponding to the target BWP indication information from a BWP activation configuration table. If the switch flag is not the first value, the UE is prohibited from obtaining the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table.

[0075] Alternatively, the BWP activation configuration can include target BWP indication information. If the target BWP indication information is a target value, the UE is prohibited from obtaining a target BWP configuration pair corresponding to the target BWP indication information from a BWP activation configuration table. If the target BWP indication information is not the target value, the UE obtains the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table.

[0076] In one example, if the SBFD frequency domain resource used by the UE changes within the BWP switching time, the base station can further obtain updated target BWP indication information corresponding to the changed SBFD frequency domain resource. The base station can send the updated target BWP indication information to the UE, and the UE can receive the updated target BWP indication information. The UE can obtain a target BWP configuration pair corresponding to the updated target BWP indication information from a BWP activation configuration table.

[0077] The base station can send the updated BWP activation configuration to the UE through a DCI message, or a MAC-CE message, or an RRC message. In this way, the UE can receive the updated BWP activation configuration, and the updated BWP activation configuration can include the updated target BWP indication information.

[0078] As can be seen from the above technical solutions, in the use of flexible BWP configuration in a multi-carrier, the UE is configured with flexible SBFD frequency domain resources (such as downlink frequency domain resources and uplink frequency domain resources) by BWP, which is used to support data transmission in a TDD system. This improves resource utilization, network coverage, and network capacity, increases uplink transmission resources and cell coverage, reduces uplink transmission delay, and increases uplink transmission capacity.

[0079] In one example of the present application, a resource allocation method is proposed, which can be applied to a base station, as shown in Figure 2A The method can include the following steps:

[0080] In step 211, the SBFD resource allocation information is sent to the UE, and the SBFD resource allocation information is used to indicate the SBFD frequency domain resources configured in the multiple carriers in the carrier group, or the SBFD frequency domain resources configured in each of the multiple carriers. In the SBFD frequency domain resources configured in the multiple carriers in the carrier group, there are at least one set of opposite time slots in different carriers in the carrier group. In the SBFD frequency domain resources configured in each of the multiple carriers, there are at least one set of opposite time slots in the carrier. The opposite time slots include uplink time slots and downlink time slots, that is, one is an uplink time slot and the other is a downlink time slot.

[0081] In step 212, the SBFD configuration information corresponding to the carrier is sent to the UE, and the SBFD configuration information is used to indicate that the SBFD frequency domain resources on the carrier are valid or invalid.

[0082] In one example of the present application, a resource allocation method is provided, which can be applied to a UE, as shown in Figure 2B As shown in the flowchart of the resource allocation method, the method can include the following steps:

[0083] In step 221, the SBFD resource allocation information sent by the base station is received, and the SBFD resource allocation information is used to indicate the SBFD frequency domain resources configured in the multiple carriers in the carrier group, or the SBFD frequency domain resources configured in each of the multiple carriers. In the SBFD frequency domain resources configured in the multiple carriers in the carrier group, there are at least one set of opposite time slots in different carriers in the carrier group. In the SBFD frequency domain resources configured in each of the multiple carriers, there are at least one set of opposite time slots in the carrier.

[0084] In step 222, the SBFD configuration information corresponding to the carrier sent by the base station is received, and the SBFD configuration information is used to indicate that the SBFD frequency domain resources on the carrier are valid or invalid.

[0085] In one example, the SBFD resource allocation information used to indicate the SBFD frequency domain resources configured in the multiple carriers in the carrier group can include but is not limited to: the SBFD resource allocation information can include a first allocation indication and a second allocation indication, and for each of the multiple carriers, the first allocation indication is used to configure all time slots included in the carrier as Flexible time slots, and the second allocation indication is used to indicate that each Flexible time slot is used for an uplink time slot or a downlink time slot. Or,

[0086] The SBFD resource allocation information can include a third allocation indication, and for each of the multiple carriers, the third allocation indication is used to configure each time slot included in the carrier as an uplink time slot or a downlink time slot. Or,

[0087] The SBFD resource allocation information can include a fourth allocation indication and a fifth allocation indication. The fourth allocation indication is used to configure each time slot included in a first carrier in the plurality of carriers as an uplink time slot or a downlink time slot. The fifth allocation indication is used to indicate an offset between a second carrier (which can be one or two or more) and the first carrier, and the offset can be a time slot offset and / or a symbol offset.

[0088] In one example, the fifth allocation indication is further used to indicate whether the offset between the second carrier and the first carrier is effective, such as indicating that the offset is effective, or indicating that the offset is not effective.

[0089] In one example, when the base station sends the SBFD configuration information corresponding to the carrier to the UE, and the UE receives the SBFD configuration information corresponding to the carrier sent by the base station, for a third carrier in the plurality of carriers, if the SBFD configuration information includes a deactivation indication of the third carrier, the deactivation indication is used to deactivate the third carrier, and the deactivation indication is used to indicate that the SBFD frequency domain resource on the third carrier is invalid.

[0090] Alternatively, for a third carrier in the plurality of carriers, if the SBFD configuration information includes an invalidation indication of the SBFD frequency domain resource on the third carrier, the invalidation indication is used to indicate that the SBFD frequency domain resource on the third carrier is invalid. In this case, the third carrier is still in an activated state, i.e., not deactivated. Since the SBFD frequency domain resource on the third carrier is invalid, the configuration on the third carrier can be a default configuration (such as using the default DL time slot and UL time slot frame structure), or the configuration on the third carrier can be the same as the configuration of the primary carrier, i.e., using the DL time slot and UL time slot frame structure of the primary carrier.

[0091] In one example, when the base station sends the SBFD configuration information corresponding to the carrier to the UE, and the UE receives the SBFD configuration information corresponding to the carrier sent by the base station, for a fourth carrier in the plurality of carriers, if the SBFD configuration information includes an activation indication and an effectiveness indication of the fourth carrier, the activation indication is used to activate the fourth carrier, and the effectiveness indication is used to indicate that the SBFD frequency domain resource on the fourth carrier is effective or ineffective.

[0092] Alternatively, for a fourth carrier in the plurality of carriers, if the SBFD configuration information includes an activation indication of the fourth carrier, the activation indication is used to activate the fourth carrier, and after the fourth carrier is activated, the SBFD frequency domain resource on the fourth carrier is directly effective, i.e., after the base station sends the SBFD resource allocation information to the UE, if the carrier corresponding to the SBFD resource allocation information is activated, the SBFD frequency domain resource on the carrier is directly effective.

[0093] From the above technical solutions, in the flexible BWP configuration of the multi-carrier, the flexible SBFD frequency domain resources (such as downlink frequency domain resources and uplink frequency domain resources) are configured for the UE by the BWP, which is used to support the data transmission of the TDD system, thereby improving the resource utilization, improving the network coverage and network capacity, increasing the uplink transmission resources and cell coverage, reducing the uplink transmission delay and increasing the uplink transmission capacity.

[0094] The above technical solutions of the present application will be described below in combination with examples.

[0095] The frame structure of the TDD can be completed by the semi-static configuration and dynamic indication. In the high layer signaling, a plurality of SFCs (Slot Format Combination) are defined by SFI (Slot Format Indicator), for example, the base station can select the time slot formats meeting the service requirements and add these time slot formats to the SFC. Some of the time slot formats can be seen in Table 1, D represents the DL symbol, U represents the UL symbol, and F represents the flexible symbol. For each SFC, a fixed ID is used for identification, and one or more time slot format types are included.

[0096] Table 1

[0097]

[0098] After completing the SFI configuration, the base station sends a plurality of time slot format combinations to the UE in the RRC message. After configuring the plurality of time slot format combinations through the RRC signaling, the base station informs the UE of the index of the currently used SFC through the periodic PDCCH in the DCI format 2_0. After the UE correctly receives the information of the DCI format 2_0, the time slot format of each time slot within a certain period is determined according to the value of the SFC index. At this point, the base station and the UE complete the configuration of the frame structure through the dynamic indication, and the uplink and downlink data transmission can be performed.

[0099] For resource allocation, it can be divided into time domain resource allocation and frequency domain resource allocation (taking the resource allocation of downlink channel as an example). Time domain resource allocation: the Time domain resource assignment field in DCI indicates the time domain position of the downlink channel, and the field has 4 bits, with a value of 0-15. Assuming the value is m, m+1 indicates the row index of the time domain resource allocation table, and the information in the row indicates the time domain resource of the PDSCH. There are two ways to indicate: one is to indicate three information: the slot offset between the PDSCH and the PDCCH scheduling the PDSCH, the starting symbol of the PDSCH in the slot, and the symbol length of the PDSCH. The other is to indicate the slot offset between the PDSCH and the PDCCH scheduling the PDSCH, an SLIV value, and the user equipment calculates the starting symbol and the number of symbols of the PDSCH according to the SLIV value.

[0100] Frequency domain resource allocation: the Frequency domain resource assignment field in DCI indicates the frequency domain resource allocation of the downlink channel, and the PDSCH frequency domain resource allocation is divided into Type 0 and Type 1. Type 0 supports non-continuous resource allocation, obtains frequency diversity gain, and Type 1 supports continuous resource allocation, which can reduce the number of bits required by the field, and DCI format 1_0 only supports Type 1.

[0101] Type 0: For non-continuous resource allocation type, one RBG is one VRB group, which is composed of P consecutive VRBs, and the number is determined by the high-layer parameter rbg-Size and the BWP bandwidth. In the Type 0 resource allocation type, the Frequency domain resource assignment is used as a bitmap to indicate which RBG is allocated to the downlink channel, and each bit in the bitmap represents an RBG, and the highest bit corresponds to RBG0. In this way, bit 1 indicates that the RBG is allocated to the downlink channel, and bit 0 indicates that it is not a downlink channel resource.

[0102] Type 1: The frequency domain resource indication field will not be a bitmap, but will indicate an RIV (Resource Indicator Value) value, and the UE calculates the starting RB and the number of occupied RBs through the value.

[0103] In a TDD system, the frame structure is divided into UL slots, DL slots and flexible slots (F slots) according to time slots. The symbols in the flexible slots can be configured as UL symbols, DL symbols and F symbols. The F symbols can be used for UL, DL or GP. The uplink data can be transmitted in the UL slots, UL symbols or F symbols in the flexible slots. The uplink data cannot be transmitted in the DL slots or DL symbols in the flexible slots. The downlink data can be transmitted in the DL slots, DL symbols or F symbols in the flexible slots. The downlink data cannot be transmitted in the UL slots or UL symbols in the flexible slots.

[0104] Full-duplex communication is implemented through SBFD, that is, SBFD sub-band resources (sub-band, frequency domain resource) are configured in the BWP. The SBFD sub-band resources include uplink sub-band resources and downlink sub-band resources. At the same time, different direction data is transmitted through the SBFD sub-band resources. For example, the SBFD sub-band resources are configured in the BWP of the DL slot, and the uplink data is transmitted through the SBFD sub-band resources, so that the uplink data is transmitted in the DL slot. The SBFD sub-band resources are configured in the BWP of the DL symbol of the flexible slot, and the uplink data is transmitted through the SBFD sub-band resources, so that the uplink data is transmitted in the DL symbol of the flexible slot.

[0105] The SBFD sub-band resources are configured in the BWP of the UL slot, and the downlink data is transmitted through the SBFD sub-band resources, so that the downlink data is transmitted in the UL slot. The SBFD sub-band resources are configured in the BWP of the UL symbol of the flexible slot, and the downlink data is transmitted through the SBFD sub-band resources, so that the downlink data is transmitted in the UL symbol of the flexible slot.

[0106] In one example, the SBFD sub-band resources can be frequency domain resources in SBFD slots or SBFD symbols. The SBFD symbol can be a symbol configured with SBFD sub-band. In the SBFD sub-band of these SBFD symbols, the base station and the UE can perform full-duplex communication, that is, on the SBFD sub-band resources, uplink transmission, downlink transmission or uplink and downlink transmission can be performed.

[0107] Among them, the SBFD sub-band resources can be explicitly indicated as uplink, downlink or Flexible. When the SBFD sub-band resources are indicated as Flexible, the SBFD sub-band resources can be flexibly scheduled for uplink or downlink. If the SBFD sub-band resources are not explicitly indicated, it means Flexible, and can be used to transmit uplink or downlink data. The configuration of the SBFD symbol can include which symbols in the DL slot, UL slot and F slot are used for SBFD transmission, and the period and starting point of implementation, etc.

[0108] Wherein, the SBFD subband resource indicated as uplink is called as uplink subband resource, short for UL SB, i.e. the SBFD subband resource is used for uplink. The SBFD subband resource indicated as downlink is called as downlink subband resource, short for DL SB, i.e. the SBFD subband resource is used for downlink. The frequency domain resource indicated as guard subband is called as guard subband resource, short for GB, i.e. used for guard subband.

[0109] Wherein, for the half-duplex UE supporting SBFD function, the UE can learn the configuration related to SBFD subband resource, but the UE can only receive DL data or transmit UL data at the same time (symbol) whether in the same carrier or different carriers. For the full-duplex UE supporting SBFD function, the UE can learn the configuration related to SBFD subband resource, and the UE can receive DL data and transmit UL data at the same time (symbol) whether in the same carrier or different carriers.

[0110] The base station configures SBFD subband resource for the half-duplex UE or full-duplex UE supporting SBFD function. The SBFD subband resource is configured for the UE in the DL slot or DL symbol, and the SBFD subband resource is used for transmitting UL data, i.e. the SBFD subband resource can be uplink subband resource. The DL symbol configured with SBFD subband resource is SBFD symbol, and in the SBFD symbol, in addition to the uplink subband resource, there are downlink subband resource and guard subband resource, and the guard subband resource is located between the uplink subband resource and the downlink subband resource.

[0111] The SBFD subband resource is configured for the UE in the UL slot or UL symbol, and the SBFD subband resource is used for transmitting DL data, i.e. the SBFD subband resource can be downlink subband resource. The UL symbol configured with SBFD subband resource is SBFD symbol, and in the SBFD symbol, in addition to the downlink subband resource, there are uplink subband resource and guard subband resource, and the guard subband resource is located between the uplink subband resource and the downlink subband resource.

[0112] The SBFD subband resource is configured for the UE in the F slot or F symbol, and the SBFD subband resource is used for transmitting DL data (or UL data), i.e. the SBFD subband resource can be downlink subband resource (or uplink subband resource). The F symbol configured with SBFD subband resource is SBFD symbol, and in the SBFD symbol, in addition to the downlink subband resource (or uplink subband resource), there are uplink subband resource (or downlink subband resource) and guard subband resource, and the guard subband resource is located between the uplink subband resource and the downlink subband resource.

[0113] In one example, the base station in the subsequent embodiments is a full-duplex base station that can handle DL data and UL data at the same time. The UE in the subsequent embodiments is a half-duplex UE or a full-duplex UE supporting the SBFD function, which can handle only DL data or UL data at the same time regardless of the same carrier and different carriers, and can obtain all the configuration parameters of the SBFD. The full-duplex UE can handle DL data and UL data at the same time regardless of the same carrier and different carriers, and can obtain all the configuration parameters of the SBFD.

[0114] To support FD communication, SBFD sub-band resources can be configured semi-statically, such as through RRC signaling, or dynamically, such as through DCI.

[0115] In the TDD FD mode, in one example, a resource allocation method under a multi-carrier is proposed. The resource allocation method is related to the resource allocation of the TDD full-duplex uplink and downlink physical channel under a multi-carrier. The method mainly solves the problems of how to allocate resources, scheduling, and activation under a multi-carrier. The resource allocation method is described below.

[0116] First, BWP frequency domain resource configuration, i.e., SBFD resource allocation based on BWP.

[0117] The base station sends BWP frequency domain resource configuration information to the UE, and the UE receives the BWP frequency domain resource configuration information sent by the base station. The BWP frequency domain resource configuration information includes the mapping relationship between the resource identifier and the SBFD frequency domain resource (i.e., frequency resource), and the resource identifier can include the BWP identifier and the carrier identifier.

[0118] In one example, for a TDD system, when the base station configures the BWP for the UE under a multi-carrier, the same downlink BWP identifier and uplink BWP identifier can be configured in different carriers. The frequency resources corresponding to the same downlink BWP identifier and uplink BWP identifier can be different, i.e., the SBFD frequency domain resource corresponding to the uplink BWP identifier is different from the SBFD frequency domain resource corresponding to the downlink BWP identifier.

[0119] In one example, the size of the SBFD frequency domain resource corresponding to the uplink BWP identifier can be different from or the same as the size of the SBFD frequency domain resource corresponding to the downlink BWP identifier.

[0120] In one example, the SBFD frequency domain resource is a frequency domain resource configured in the carrier indicated by the carrier identifier, and the SBFD frequency domain resource is a frequency domain resource corresponding to the BWP identifier. Different carrier identifiers indicate SBFD intra-band carriers (Intra-band CA) or SBFD inter-band carriers (Inter-band CA).

[0121] For example, when the base station configures the BWP for the UE, the uplink BWP identifier and the downlink BWP identifier are configured. The uplink BWP identifier and the downlink BWP identifier can be the same, and the uplink BWP identifier corresponds to the first carrier identifier, and the downlink BWP identifier corresponds to the second carrier identifier. Based on this, the BWP frequency domain resource configuration information includes the mapping relationship between the uplink BWP identifier, the first carrier identifier and the SBFD frequency domain resource, and the mapping relationship between the downlink BWP identifier, the second carrier identifier and the SBFD frequency domain resource.

[0122] Referring to Figure 3A As shown in the figure, in the case of multiple carriers, the DL BWP and the UL BWP are asymmetrically allocated resources. Each carrier has a BWP. The uplink BWP identifier and the downlink BWP identifier are both BWP1. The uplink BWP identifier is UL BWP1, and the downlink BWP identifier is DL BWP1. The same downlink BWP identifier and uplink BWP identifier form a pair of BWP groups. The second carrier identifier corresponding to the DL BWP1 is CC1, and the downlink BWP is in CC1. The first carrier identifier corresponding to the UL BWP1 is CC2, and the uplink BWP is in CC2.

[0123] The frequency resource corresponding to the DL BWP1 can be different from the frequency resource corresponding to the UL BWP1. For example, the base station allocates SBFD frequency domain resources for the DL BWP1 on CC1. The SBFD frequency domain resource is from the 0th PRB to the 100th PRB. The base station allocates SBFD frequency domain resources for the UL BWP1 on CC2. The SBFD frequency domain resource is from the 0th PRB to the 100th PRB. Obviously, since the base station configures the SBFD frequency domain resource on different CCs, the frequency resources are not the same.

[0124] For example, when the base station configures the BWP for the UE, the uplink BWP identifier and the downlink BWP identifier are configured. The uplink BWP identifier and the downlink BWP identifier can be the same, and the uplink BWP identifier corresponds to the first carrier identifier, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier. Based on this, the BWP frequency domain resource configuration information includes the mapping relationship between the uplink BWP identifier, the first carrier identifier and the SBFD frequency domain resource, the mapping relationship between the uplink BWP identifier, the second carrier identifier and the SBFD frequency domain resource, and the mapping relationship between the downlink BWP identifier, the second carrier identifier and the SBFD frequency domain resource.

[0125] Referring to Figure 3BAs shown, it is a schematic diagram of asymmetric resource allocation of DL BWP and UL BWP in the case of multi-carrier, and the resource of DL BWP is less than the resource of UL BWP. The uplink BWP identifier and the downlink BWP identifier are both BWP1, the uplink BWP identifier is UL BWP1, and the downlink BWP identifier is DL BWP1. The same downlink BWP identifier and uplink BWP identifier form a pair of BWP group. The second carrier identifier corresponding to DL BWP1 is CC2, and the downlink BWP is on CC2. The first carrier identifier corresponding to UL BWP1 is CC1, and the second carrier identifier corresponding to UL BWP1 is CC2, that is, the uplink BWP is on CC1 and CC2.

[0126] The frequency resource corresponding to DL BWP1 and the frequency resource corresponding to UL BWP1 can be different, and the size of the frequency resource corresponding to DL BWP1 and the size of the frequency resource corresponding to UL BWP1 can be different, such as the frequency resources can partially overlap or the frequency resources do not overlap. For example, the base station allocates SBFD frequency domain resources for UL BWP1 on CC1, and the SBFD frequency domain resources are from the 0th PRB to the 100th PRB. The base station allocates SBFD frequency domain resources for UL BWP1 on CC2, and the SBFD frequency domain resources are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for DL BWP1 on CC2, and the SBFD frequency domain resources are from the 51st PRB to the 100th PRB.

[0127] For example, when the base station configures the BWP for the UE, the uplink BWP identifier and the downlink BWP identifier are configured. The uplink BWP identifier and the downlink BWP identifier can be the same, and the downlink BWP identifier corresponds to the first carrier identifier, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier at the same time. Based on this, the BWP frequency domain resource configuration information includes the mapping relationship between the downlink BWP identifier, the first carrier identifier and the SBFD frequency domain resource, the mapping relationship between the downlink BWP identifier, the second carrier identifier and the SBFD frequency domain resource, and the mapping relationship between the uplink BWP identifier, the second carrier identifier and the SBFD frequency domain resource.

[0128] Referring to Figure 3CAs shown, it is a schematic diagram of asymmetric resource allocation of DL BWP and UL BWP in the case of multi-carrier, and the resource of DL BWP is greater than the resource of UL BWP. The uplink BWP identifier and the downlink BWP identifier are both BWP1, the uplink BWP identifier is UL BWP1, and the downlink BWP identifier is DL BWP1. The same downlink BWP identifier and uplink BWP identifier form a pair of BWP group. The first carrier identifier corresponding to the DL BWP1 is CC1, and the second carrier identifier corresponding to the DL BWP1 is CC2, that is, the downlink BWP is on CC1 and CC2. The second carrier identifier corresponding to the UL BWP1 is CC2, that is, the uplink BWP is on CC2.

[0129] The frequency resource corresponding to the DL BWP1 and the frequency resource corresponding to the UL BWP1 can be different, and the size of the frequency resource corresponding to the DL BWP1 and the size of the frequency resource corresponding to the UL BWP1 can be different, such as the frequency resources can be partially overlapped or the frequency resources are not overlapped. For example, the base station allocates SBFD frequency domain resources for the DL BWP1 on CC1, and the SBFD frequency domain resources are from the 0th PRB to the 100th PRB. The base station allocates SBFD frequency domain resources for the UL BWP1 on CC2, and the SBFD frequency domain resources are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for the DL BWP1 on CC2, and the SBFD frequency domain resources are from the 51st PRB to the 100th PRB.

[0130] For example, when the base station configures the BWP for the UE, the uplink BWP identifier and the downlink BWP identifier are configured. The uplink BWP identifier and the downlink BWP identifier can be the same, and the uplink BWP identifier and the downlink BWP identifier correspond to the first carrier identifier at the same time, and the uplink BWP identifier and the downlink BWP identifier correspond to the second carrier identifier at the same time. Based on this, the BWP frequency domain resource configuration information includes the mapping relationship between the downlink BWP identifier, the first carrier identifier and the SBFD frequency domain resource, the mapping relationship between the downlink BWP identifier, the second carrier identifier and the SBFD frequency domain resource, the mapping relationship between the uplink BWP identifier, the first carrier identifier and the SBFD frequency domain resource, and the mapping relationship between the uplink BWP identifier, the second carrier identifier and the SBFD frequency domain resource.

[0131] Referring to Figure 3DAs shown, it is a schematic diagram of asymmetric resource allocation of DL BWP and UL BWP in a multi-carrier case, the SBFD configurations of the two carriers are the same, and the resources of the two carriers belong to the same BWP. The uplink BWP identifier and the downlink BWP identifier are both BWP1, the uplink BWP identifier is UL BWP1, and the downlink BWP identifier is DL BWP1. The downlink BWP identifier and the uplink BWP identifier form a pair of BWP groups. The first carrier identifier corresponding to the DL BWP1 and the UL BWP1 is CC1, and the second carrier identifier corresponding to the DL BWP1 and the UL BWP1 is CC2, that is, the downlink BWP is on CC1 and CC2, and the uplink BWP is on CC1 and CC2.

[0132] The base station allocates SBFD frequency domain resources for the UL BWP1 on CC1, and the SBFD frequency domain resources are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for the DL BWP1 on CC1, and the SBFD frequency domain resources are from the 51st PRB to the 100th PRB.

[0133] The base station allocates SBFD frequency domain resources for the UL BWP1 on CC2, and the SBFD frequency domain resources are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for the DL BWP1 on CC2, and the SBFD frequency domain resources are from the 51st PRB to the 100th PRB.

[0134] For example, when the base station configures the BWP for the UE, the uplink BWP identifier and the downlink BWP identifier are configured. The uplink BWP identifier and the downlink BWP identifier can be different, and the uplink BWP identifier corresponds to the first carrier identifier, and the downlink BWP identifier corresponds to the second carrier identifier. Based on this, the BWP frequency domain resource configuration information includes the mapping relationship between the uplink BWP identifier, the first carrier identifier and the SBFD frequency domain resources, and the mapping relationship between the downlink BWP identifier, the second carrier identifier and the SBFD frequency domain resources.

[0135] Referring to Figure 3E As shown, it is a schematic diagram of asymmetric resource allocation of DL BWP and UL BWP in a multi-carrier case. The uplink BWP identifier and the downlink BWP identifier are different, the uplink BWP identifier is UL BWP2, and the downlink BWP identifier is DL BWP1. The second carrier identifier corresponding to the DL BWP1 is CC1, and the downlink BWP is on CC1. The first carrier identifier corresponding to the UL BWP2 is CC2, and the uplink BWP is on CC2.

[0136] The base station allocates SBFD frequency domain resources for the DL BWP1 on the CC1, which are from the 0th PRB to the 100th PRB. The base station allocates SBFD frequency domain resources for the UL BWP2 on the CC2, which are from the 0th PRB to the 100th PRB.

[0137] For example, when the base station configures a BWP for the UE, the base station configures a first uplink BWP identifier, a first downlink BWP identifier, a second uplink BWP identifier, and a second downlink BWP identifier, the first uplink BWP identifier is the same as the first downlink BWP identifier, the second uplink BWP identifier is the same as the second downlink BWP identifier, the first uplink BWP identifier is different from the second uplink BWP identifier, and the first downlink BWP identifier is different from the second downlink BWP identifier. The first uplink BWP identifier and the first downlink BWP identifier correspond to a first carrier identifier, and the second uplink BWP identifier and the second downlink BWP identifier correspond to a second carrier identifier.

[0138] Based on this, the BWP frequency domain resource configuration information includes a first downlink BWP identifier, a first carrier identifier, and a mapping relationship of SBFD frequency domain resources, a first uplink BWP identifier, a first carrier identifier, and a mapping relationship of SBFD frequency domain resources, a second downlink BWP identifier, a second carrier identifier, and a mapping relationship of SBFD frequency domain resources, a second uplink BWP identifier, and a second carrier identifier, and a mapping relationship of SBFD frequency domain resources.

[0139] Referring to Figure 3F As shown in the figure, in the case of multiple carriers, the DL BWP and the UL BWP are asymmetrically allocated resources, the SBFD configurations of the two carriers are the same, and the resources of the two carriers belong to different BWP. The uplink BWP identifier includes UL BWP1 and UL BWP2, and the downlink BWP identifier includes DL BWP1 and DL BWP2.

[0140] Among them, UL BWP1 and DL BWP1 form a pair of BWP groups, and UL BWP2 and DL BWP2 form another pair of BWP groups. The first carrier identifier corresponding to the DL BWP1 and the UL BWP1 is CC1, and the second carrier identifier corresponding to the DL BWP2 and the UL BWP2 is CC2, that is, the DL BWP1 is on the CC1, the DL BWP2 is on the CC1, the UL BWP1 is on the CC1, and the UL BWP2 is on the CC1.

[0141] The base station allocates SBFD frequency domain resources for the UL BWP1 on the CC1, which are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for the DL BWP1 on the CC1, which are from the 51st PRB to the 100th PRB.

[0142] The base station allocates SBFD frequency domain resources for the UL BWP2 on the CC2, which are from the 0th PRB to the 50th PRB. The base station allocates SBFD frequency domain resources for the DL BWP2 on the CC2, which are from the 51st PRB to the 100th PRB.

[0143] In one example, after the base station configures the BWP frequency domain resources for the UE, the base station can send the BWP frequency domain resource configuration information to the UE. The BWP frequency domain resource configuration information includes the mapping relationship between the BWP identifier (such as the downlink BWP identifier and the uplink BWP identifier), the carrier identifier, and the SBFD frequency domain resource.

[0144] Second, the BWP activation configuration table. The base station and the UE can pre-configure the same BWP activation configuration table, such as pre-configuring the BWP activation configuration table at the physical layer of the base station and the UE. Alternatively, the base station can obtain the BWP activation configuration table and send the BWP activation configuration table to the UE through the RRC message, such as the base station broadcasting the BWP activation configuration table to multiple UEs through the RRC message.

[0145] In one example, the BWP activation configuration table (also referred to as the BWP matching pair activation indication table) can include the mapping relationship between the BWP indication information and the BWP configuration pair. For each BWP configuration pair in the BWP activation configuration table, the BWP configuration pair can include the downlink BWP identifier and the carrier identifier corresponding to the downlink BWP identifier, the uplink BWP identifier and the carrier identifier corresponding to the uplink BWP identifier. The downlink BWP identifier and the uplink BWP identifier can be the same or different. The carrier identifier corresponding to the downlink BWP identifier and the carrier identifier corresponding to the uplink BWP identifier can be the same or different.

[0146] Referring to Table 2, as an example of the BWP activation configuration table, 16 BWP configuration pairs are given in the BWP activation configuration table, and indicated by 4-bit BWP indication information.

[0147] Table 2

[0148]

[0149]

[0150] As can be seen from Table 2, 4 bits can be used to represent the BWP indication information, and each BWP indication information corresponds to a BWP configuration pair. The BWP configuration pair is used to indicate the downlink BWP identifier and the carrier identifier corresponding to the downlink BWP identifier, the uplink BWP identifier and the carrier identifier corresponding to the uplink BWP identifier.

[0151] In one example, the BWP activation configuration table (also referred to as BWP matching pair activation indication table) can include a mapping relationship between the BWP indication information and the BWP configuration pair. For each BWP configuration pair in the BWP activation configuration table, the BWP configuration pair can include a first configuration sub-pair and a second configuration sub-pair.

[0152] The first configuration sub-pair can include a first downlink BWP identifier and a carrier identifier corresponding to the first downlink BWP identifier, a first uplink BWP identifier and a carrier identifier corresponding to the first uplink BWP identifier. The first downlink BWP identifier and the first uplink BWP identifier can be the same or different. The carrier identifier corresponding to the first downlink BWP identifier and the carrier identifier corresponding to the first uplink BWP identifier can be the same or different.

[0153] The second configuration sub-pair can include a second downlink BWP identifier and a carrier identifier corresponding to the second downlink BWP identifier, a second uplink BWP identifier and a carrier identifier corresponding to the second uplink BWP identifier. The second downlink BWP identifier and the second uplink BWP identifier can be the same or different. The carrier identifier corresponding to the second downlink BWP identifier and the carrier identifier corresponding to the second uplink BWP identifier can be the same or different.

[0154] Referring to Table 3, as an example of the BWP activation configuration table, four BWP configuration pairs are given in the BWP activation configuration table, and indicated by 4-bit BWP indication information. Of course, here is just an example of four BWP configuration pairs, and the number of BWP configuration pairs is greater than four, which is not limited.

[0155] Table 3

[0156]

[0157] As can be seen from Table 3, 4 bits are used to represent the BWP indication information, and the BWP indication information corresponds to a BWP configuration pair. The BWP configuration pair includes a first configuration sub-pair and a second configuration sub-pair. The first configuration sub-pair indicates a downlink BWP identifier and a carrier identifier corresponding to the downlink BWP identifier, an uplink BWP identifier and a carrier identifier corresponding to the uplink BWP identifier. The second configuration sub-pair indicates a downlink BWP identifier and a carrier identifier corresponding to the downlink BWP identifier, an uplink BWP identifier and a carrier identifier corresponding to the uplink BWP identifier.

[0158] Third, BWP activation configuration, that is, the base station can trigger the UE to obtain the target BWP configuration pair through the BWP activation configuration, and determine the target SBFD frequency domain resource associated with the target BWP configuration pair.

[0159] In one example, the BWP activation configuration process can include the following steps:

[0160] Step S11, the base station sends a BWP activation configuration to the UE, the BWP activation configuration including target BWP indication information, such as any BWP indication information in the BWP activation configuration table, such as 0000, 0001.

[0161] In one example, the base station sends the BWP activation configuration to the UE through a DCI message, and the UE receives the BWP activation configuration through the DCI message. Alternatively, the base station sends the BWP activation configuration to the UE through a MAC-CE message, and the UE receives the BWP activation configuration through the MAC-CE message. Alternatively, the base station sends the BWP activation configuration to the UE through an RRC message, and the UE receives the BWP activation configuration through the RRC message.

[0162] Step S12, after receiving the BWP activation configuration, the UE obtains a target BWP configuration pair corresponding to the target BWP indication information (located in the BWP activation configuration) from the BWP activation configuration table. The target BWP configuration pair can include a target BWP identifier and a target carrier identifier.

[0163] In one example, the UE can obtain a target BWP configuration pair from the BWP activation configuration table in Table 2. The target BWP configuration pair includes a target downlink BWP identifier and a target uplink BWP identifier, which can be the same or different. The target BWP configuration pair also includes a carrier identifier corresponding to the target downlink BWP identifier and a carrier identifier corresponding to the target uplink BWP identifier, which can be the same or different.

[0164] In one example, the UE can obtain a target BWP configuration pair from the BWP activation configuration table in Table 3, which includes a target first configuration sub-pair and a target second configuration sub-pair. The target first configuration sub-pair includes a target first downlink BWP identifier, a target first uplink BWP identifier, a carrier identifier corresponding to the target first downlink BWP identifier, and a carrier identifier corresponding to the target first uplink BWP identifier. The target first downlink BWP identifier and the target first uplink BWP identifier can be the same or different. The carrier identifier corresponding to the target first downlink BWP identifier and the carrier identifier corresponding to the target first uplink BWP identifier can be the same or different.

[0165] The target second configuration sub-pair can include a target second downlink BWP identifier, a target second uplink BWP identifier, a carrier identifier corresponding to the target second downlink BWP identifier, and a carrier identifier corresponding to the target second uplink BWP identifier. The target second downlink BWP identifier and the target second uplink BWP identifier can be the same or different. The carrier identifier corresponding to the target second downlink BWP identifier and the carrier identifier corresponding to the target second uplink BWP identifier can be the same or different.

[0166] In one example, the BWP activation configuration can include a switch flag and the target BWP indication information. If the switch flag is a first value, the UE can obtain the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table, that is, step S12 and the subsequent steps can be performed. If the switch flag is not the first value, the UE can be prohibited from obtaining the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table, that is, step S12 and the subsequent steps can not be performed.

[0167] For example, the switch flag and the target BWP indication information can be carried in the DCI message. For example, the DCI message includes a Bandwidth part indicator (bandwidth part indicator) and a switch flag. If the switch flag is 00 (not the first value), the Bandwidth part indicator is used for original BWP switching indication. If the switch flag is 01 (not the first value), the Bandwidth part indicator is used for BWP indication of SBFD in a single carrier case. The processing procedures of the switch flag being 00 and 01 are not limited.

[0168] If the switch flag is 10 (for example, 10 is the first value), the Bandwidth part indicator is used for BWP indication of SBFD in a multi-carrier case. That is, the Bandwidth part indicator is used as the target BWP indication information, and the target BWP indication information is used to indicate the target BWP configuration pair.

[0169] Referring to Table 4, one example of the DCI message is shown, and the content of the DCI message is not limited.

[0170] Table 4

[0171]

[0172] In one example, the BWP activation configuration can include target BWP indication information. If the target BWP indication information is a target value (e.g., any value other than the BWP indication information in Table 2 or Table 3), the UE is prohibited from obtaining the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table, i.e., step S12 and subsequent steps can not be performed. Alternatively, if the target BWP indication information is not a target value (e.g., any value in Table 2 or Table 3), the UE obtains the target BWP configuration pair corresponding to the target BWP indication information from the BWP activation configuration table, i.e., step S12 can be performed.

[0173] For example, a new Bandwidth part indicator for SBFD formultiple carriers IE (Bandwidth part indicator for SBFD for multiple carriers) is added in the DCI message to distinguish the Bandwidth part indicator. Referring to Table 5, an example of the DCI message is shown.

[0174] Table 5

[0175]

[0176] In step S13, the UE determines the target SBFD frequency domain resource associated with the target BWP configuration pair based on the BWP frequency domain resource configuration information. For example, since the target BWP configuration pair includes the target BWP identifier and the target carrier identifier, and the BWP frequency domain resource configuration information includes the mapping relationship between the BWP identifier, the carrier identifier, and the SBFD frequency domain resource, the UE can determine the target SBFD frequency domain resource associated with the target BWP identifier and the target carrier identifier based on the mapping relationship between the BWP identifier, the carrier identifier, and the SBFD frequency domain resource.

[0177] In step S14, the UE transmits data based on the target SBFD frequency domain resource.

[0178] For example, if the target SBFD frequency domain resource includes the BWP frequency domain resource of the uplink BWP, the UE can send data (e.g., application data or signals, etc.) on the BWP frequency domain resource of the uplink BWP.

[0179] For example, if the target SBFD frequency domain resource includes the BWP frequency domain resource of the downlink BWP, the UE can receive data (e.g., application data or signals, etc.) on the BWP frequency domain resource of the downlink BWP.

[0180] In step S15, the base station determines the target SBFD frequency domain resource associated with the target BWP configuration pair (i.e., the target BWP configuration pair corresponding to the UE) based on the BWP frequency domain resource configuration information.

[0181] Step S16, the base station transmits data with the UE based on the target SBFD frequency domain resource.

[0182] For example, if the target SBFD frequency domain resource includes the BWP frequency domain resource of the uplink BWP, the base station can receive data, such as application data or signals, on the BWP frequency domain resource of the uplink BWP.

[0183] If the target SBFD frequency domain resource includes the BWP frequency domain resource of the downlink BWP, the base station can transmit data, such as application data or signals, on the BWP frequency domain resource of the downlink BWP.

[0184] Fourth, switching of BWP activation configuration. After the base station sends the BWP activation configuration to the UE, if the SBFD frequency domain resource used by the UE changes within the BWP switching time, the base station can also obtain the updated BWP activation configuration. The updated BWP activation configuration includes updated target BWP indication information corresponding to the changed SBFD frequency domain resource.

[0185] The base station sends the updated BWP activation configuration to the UE. The UE obtains the target BWP configuration pair corresponding to the updated target BWP indication information from the BWP activation configuration table. Based on the BWP frequency domain resource configuration information, the UE determines the target SBFD frequency domain resource associated with the target BWP configuration pair. Wherein, the base station sends the updated BWP activation configuration to the UE through DCI message, or MAC-CE message, or RRC message.

[0186] Referring to Figure 4A Fig. 1 shows a schematic diagram of single BWP matching pair activation and switching in a multi-carrier case. DL BWP#1 (downlink BWP1) is on CC1, UL BWP#1 (uplink BWP1) is on CC1, BWP#2 (downlink BWP2 and uplink BWP2) is on CC2, DL BWP#3 (downlink BWP3) is on CC3, and UL BWP#3 (uplink BWP1) is on CC3.

[0187] DL BWP#1 and UL BWP#1 have asymmetric frequency domain resource allocation, DL BWP#3 and UL BWP#3 have asymmetric frequency domain resource allocation. DL BWP#3 in DL BWP#3 and UL BWP#3 has non-continuous resource allocation. The DL BWP and UL BWP of BWP#2 occupy the same frequency domain resource allocation.

[0188] Referring to Figure 4AAs shown, within the BWP switching time, first, the base station activates DL BWP#1 and UL BWP#1 on CC1 through a DCI message. Then, the base station notifies the UE to switch DL BWP#1 and UL BWP#1 on CC1 to BWP#2 on CC2 through a DCI message. Finally, the base station notifies the UE to switch BWP#2 on CC2 to DL BWP#3 and UL BWP#3 on CC3 through a DCI message.

[0189] The abscissa is Time / Event, and the ordinate is Frequency. BWP-In activityTimer Expiry indicates that the DCI activity timer expires, that is, switching is performed within the BWP switching time.

[0190] Referring to Figure 4B As shown, a schematic diagram of multiple BWP switching in a multi-carrier case is shown, which shows a schematic diagram of multiple BWP matching pair activation and switching. DL BWP#1 (downlink BWP1) is on CC1, UL BWP#1 (uplink BWP1) is on CC1, BWP#2 (downlink BWP2 and uplink BWP2) is on CC2, DL BWP#3 (downlink BWP3) is on CC3, and UL BWP#3 (uplink BWP1) is on CC3.

[0191] DL BWP#1 and UL BWP#1 have asymmetric frequency domain resource allocation, DL BWP#3 and UL BWP#3 have asymmetric frequency domain resource allocation. DL BWP#3 in DL BWP#3 and UL BWP#3 has non-continuous resource allocation. The DL BWP and UL BWP of BWP#2 occupy the same frequency domain resource allocation.

[0192] Within the BWP switching time, the base station activates DL BWP#1 and UL BWP#1 on CC1, BWP#2 on CC2 through a DCI message. The base station notifies the UE to switch DL BWP#1 and UL BWP#1 on CC1, BWP#2 on CC2 to DL BWP#3 and UL BWP#3 on CC3 through a DCI message.

[0193] In one example, based on the BWP frequency domain resource configuration, the BWP activation configuration table, the BWP activation configuration, the switching of the BWP activation configuration, etc., a BWP-based SBFD frequency domain resource allocation and activation method in a multi-carrier case can be implemented. When a single BWP or multiple BWPs are configured, the BWP matching pair activation supporting SBFD is activated, such as the base station activating SBFD by indicating the BWP activation configuration.

[0194] If the carrier is deactivated, if the base station deactivates a carrier through DCI, the SBFD configuration on the carrier is invalid. If the base station activates a carrier through DCI, the DL / UL configuration is valid, but the SBFD configuration is not valid, and a 1-bit indication is needed to indicate whether the BWP-based SBFD configuration is valid.

[0195] In one example, in the BWP-based SBFD resource configuration and activation method, the base station can configure the DL / UL resources on each carrier into the same or different BWP pairs. The base station can configure one-to-one or one-to-many DL / UL BWP matching groups (with the same or different center frequencies of DL / UL BWPs) through semi-static / dynamic methods. The base station can use activation / switching of multiple BWPs or DL / UL BWP matching pairs to achieve dynamic SBFD resource configuration. The base station can dynamically adjust the SBFD configuration parameters by introducing carrier BWP activation parameters / BWP deactivation parameters in the DCI message.

[0196] In the above process, the BWP-based SBFD frequency domain resource allocation and activation method in the multi-carrier case is introduced. In this embodiment, the carrier-based SBFD frequency domain resource allocation and activation method in the multi-carrier case is also involved, which will be described below.

[0197] Fifth, carrier-based SBFD frequency domain resource allocation and activation in the multi-carrier case.

[0198] In one example, the base station can configure SBFD frequency domain resources on multiple carriers in a carrier group. The base station can send SBFD resource allocation information to the UE, which is used to indicate the SBFD frequency domain resources configured on multiple carriers in the carrier group. Among the SBFD frequency domain resources configured on multiple carriers in the carrier group, there is at least one set of opposite time slots for different carriers in the carrier group, and the opposite time slots include uplink time slots and downlink time slots, i.e., the time slot of one carrier is an uplink time slot, and the time slot of another carrier is a downlink time slot.

[0199] For example, taking a carrier group including two carriers (a first carrier and a second carrier) as an example. If the time slot k of the first carrier is an uplink time slot and the time slot k of the second carrier is a downlink time slot, it indicates that the time slot k is an opposite time slot, i.e., there is a set of opposite time slots k for different carriers in the carrier group, and the time slot k can be any time slot.

[0200] Referring to Figure 5A FIG. 1 shows a schematic diagram of SBFD frequency domain resource allocation based on multiple carriers, in which multiple carriers form SBFD frequency domain resources, such as CC1 and CC2 forming SBFD frequency domain resources.

[0201] In one example, before multiple carriers in a carrier group form SBFD frequency domain resources, different carriers in the carrier group can be the same time slot. For example, referring to Figure 5A As shown, time slot 0 of CC1 and time slot 0 of CC2 are both DL slots (i.e., downlink time slots), time slot 1 of CC1 and time slot 1 of CC2 are both DL slots, time slot 2 of CC1 and time slot 2 of CC2 are both DL slots, time slot 3 of CC1 and time slot 3 of CC2 are both UL slots (i.e., uplink time slots), and time slot 4 of CC1 and time slot 4 of CC2 are both UL slots.

[0202] In order to form SBFD frequency domain resources in multiple carriers, different carriers in the carrier group have at least one set of opposite time slots. For example, referring to Figure 5A As shown, time slot 0 of CC1 is a DL slot, and time slot 0 of CC2 is a UL slot. Time slot 1 of CC1 is a DL slot, and time slot 1 of CC2 is a UL slot. Time slot 2 of CC1 is a DL slot, and time slot 2 of CC2 is a UL slot. Time slot 3 of CC1 is a UL slot, and time slot 3 of CC2 is a DL slot. Time slot 4 of CC1 is a UL slot, and time slot 4 of CC2 is a DL slot.

[0203] Of course, the above is an example of having 5 sets of opposite time slots. In order to form SBFD frequency domain resources in multiple carriers, as long as there is at least one set of opposite time slots, it is OK. For example, time slot k is an opposite time slot, and time slot k can be any time slot. Other time slots can be opposite time slots, or the same time slots.

[0204] In one example, in order to form SBFD frequency domain resources in multiple carriers, the following methods can be used:

[0205] Method 1: By setting time slots on different carriers (e.g., CC1 and CC2, CC1 and CC2 belong to Intra-band CA) as Flexible time slots. Then, using SFI to specify whether the Flexible time slot is a DL time slot or a UL time slot. In this case, when using SFI to specify whether the Flexible time slot is a DL time slot or a UL time slot, different carriers need to have at least one set of opposite time slots, so as to form SBFD frequency domain resources in multiple carriers.

[0206] For example, when the base station sends SBFD resource allocation information to the UE, the SBFD resource allocation information includes a first allocation indication and a second allocation indication. For each of the plurality of carriers, the first allocation indication is used to configure all time slots included in the carrier as Flexible time slots, i.e., to set the time slots on different carriers as Flexible time slots. The second allocation indication is used to indicate that each Flexible time slot is used for an uplink time slot or a downlink time slot, i.e., to specify whether the Flexible time slot is a DL time slot or a UL time slot by using SFI.

[0207] When each Flexible time slot is indicated by the second allocation indication to be used for an uplink time slot or a downlink time slot, at least one set of opposite time slots needs to exist in different carriers, such as indicated by the time slot structure of Figure 5A .

[0208] Method 2: SBFD frequency domain resources are formed by different carriers (such as CC1 and CC2, CC1 and CC2 belong to Intra-band CA) being configured with different DL / UL configurations (i.e., different DL time slots or UL time slots). When different carriers are configured with DL time slots or UL time slots, at least one set of opposite time slots needs to exist in different carriers, so that SBFD frequency domain resources are formed in the plurality of carriers.

[0209] For example, when the base station sends SBFD resource allocation information to the UE, the SBFD resource allocation information can include a third allocation indication. For each of the plurality of carriers, the third allocation indication (such as DL / UL configuration) is used to configure each time slot included in the carrier as an uplink time slot or a downlink time slot.

[0210] When each time slot is configured as an uplink time slot or a downlink time slot by the third allocation indication, at least one set of opposite time slots needs to exist in different carriers, such as indicated by the time slot structure of Figure 5A .

[0211] Method 3: SBFD frequency domain resources are formed by setting an offset so that the DL / UL configuration on each carrier is different. When the offset is set, at least one set of opposite time slots needs to exist in different carriers. The offset can be a time slot offset and / or a symbol offset.

[0212] For example, when the base station sends SBFD resource allocation information to the UE, the SBFD resource allocation information can include a fourth allocation indication and a fifth allocation indication. For a first carrier (the first carrier can be any carrier) of the plurality of carriers, the fourth allocation indication is used to configure each time slot included in the first carrier as an uplink time slot or a downlink time slot. Referring toFigure 5A As shown, assuming the first carrier is CC1, the fourth allocation indication indicates the time slot structure of Figure 5A

[0213] For a second carrier (the second carrier can be at least one) other than the first carrier, the fifth allocation indication is used to indicate an offset between the second carrier and the first carrier. The fifth allocation indication can be an RRC message, and the offset is set through the RRC message. For example, for each second carrier, the fifth allocation indication is used to indicate an offset between the second carrier and the first carrier.

[0214] The offset can be a time slot offset and / or a symbol offset. When the offset is a time slot offset and a symbol offset, the maximum value of the symbol offset is the total number of symbols in a time slot. When the offset is a symbol offset, the maximum value of the symbol offset can be limited to the total number of symbols in a time slot, or the maximum value of the symbol offset can not be limited to the total number of symbols in a time slot.

[0215] For example, assuming the time slot offset is m, and the time slot offset m indicates a right offset of m time slots. Then, time slot 0 of the first carrier and time slot 0+m of the second carrier have the same time slot, such as both being an uplink time slot or both being a downlink time slot, time slot 1 of the first carrier and time slot 1+m of the second carrier have the same time slot, and so on. Assuming the time slot offset is m, and the time slot offset m indicates a left offset of m time slots. Then, time slot 0 of the first carrier and time slot 0-m of the second carrier have the same time slot, time slot 1 of the first carrier and time slot 1-m of the second carrier have the same time slot, and so on.

[0216] For example, assuming the 5 time slots of the first carrier are DL, DL, DL, UL, and UL, respectively, the time slot offset m indicates a right offset of 2 time slots, time slot 0 of the first carrier and time slot 2 of the second carrier have the same time slot, and time slot 2 of the second carrier is DL. Time slot 1 of the first carrier and time slot 3 of the second carrier have the same time slot, and time slot 3 of the second carrier is DL. Time slot 2 of the first carrier and time slot 4 of the second carrier have the same time slot, and time slot 4 of the second carrier is DL. Time slot 3 of the first carrier and time slot 0 of the second carrier (i.e., the counting continues from the last time slot to the first time slot) have the same time slot, and time slot 0 of the second carrier is UL. Time slot 4 of the first carrier and time slot 1 of the second carrier have the same time slot, and time slot 1 of the second carrier is UL. In summary, the 5 time slots of the second carrier are UL, UL, DL, DL, and DL, respectively.

[0217] ​In the case that the symbol offset is n, and the symbol offset n represents right offset n symbols, the symbol 0 of the first carrier and the symbol 0+n of the second carrier have the same symbol, the symbol 1 of the first carrier and the symbol 1+n of the second carrier have the same symbol, and so on. In the case that the symbol offset is n, and the symbol offset n represents left offset n symbols, the symbol 0 of the first carrier and the symbol 0-n of the second carrier have the same time slot, the symbol 1 of the first carrier and the symbol 1-n of the second carrier have the same time slot, and so on.

[0218] In the case that the time slot offset is m, and the symbol offset is n, the time slot offset m represents right offset m time slots, and the symbol offset n represents right offset n symbols. Then, the time slot 0 of the first carrier and the time slot 0+m of the second carrier have the same time slot, the time slot 1 of the first carrier and the time slot 1+m of the second carrier have the same time slot, the symbol 0 of the first carrier and the symbol 0+n of the second carrier have the same symbol, the symbol 1 of the first carrier and the symbol 1+n of the second carrier have the same symbol, and so on.

[0219] In the case that the time slot offset is m, and the symbol offset is n, the time slot offset m represents left offset m time slots, and the symbol offset n represents left offset n symbols. Then, the time slot 0 of the first carrier and the time slot 0-m of the second carrier have the same time slot, the time slot 1 of the first carrier and the time slot 1-m of the second carrier have the same time slot, the symbol 0 of the first carrier and the symbol 0-n of the second carrier have the same time slot, the symbol 1 of the first carrier and the symbol 1-n of the second carrier have the same time slot, and so on.

[0220] In one example, the fifth allocation indication is further used to indicate whether the offset between the second carrier and the first carrier is effective, such as indicating that the offset is effective, or indicating that the offset is not effective.

[0221] As can be seen from the above, the fifth allocation indication can include an effective indication bit. If the effective indication bit indicates that the offset between the second carrier and the first carrier is effective, such as the first value of the effective indication bit, the fifth allocation indication further includes the offset (such as the time slot offset and / or the symbol offset) between the second carrier and the first carrier. If the effective indication bit indicates that the offset between the second carrier and the first carrier is not effective, such as the second value of the effective indication bit, the fifth allocation indication can not include the offset between the second carrier and the first carrier.

[0222] At this point, the SBFD frequency domain resource allocation based on the carrier is completed. The base station configures the SBFD frequency domain resource in the multiple carriers in the carrier group, and sends the SBFD resource allocation information to the UE. The UE receives the SBFD resource allocation information, and the SBFD resource allocation information is used to indicate the SBFD frequency domain resource configured by the multiple carriers.

[0223] After the carrier-based SBFD frequency domain resource allocation is completed, the activation and deactivation of the carrier-based SBFD frequency domain resource can also be involved. For example, for each carrier, the base station can send the SBFD configuration information corresponding to the carrier to the UE. The UE receives the SBFD configuration information, which is used to indicate that the SBFD frequency domain resource on the carrier is valid or invalid. Wherein, the validity means to activate the SBFD frequency domain resource on the carrier, and the invalidity means to deactivate the SBFD frequency domain resource on the carrier.

[0224] For example, when the base station sends the SBFD configuration information to the UE, for a third carrier in the plurality of carriers, if the SBFD configuration information includes a deactivation indication of the third carrier, the deactivation indication is used to deactivate the third carrier, and the deactivation indication is used to indicate that the SBFD frequency domain resource on the third carrier is invalid.

[0225] When the base station sends the SBFD configuration information to the UE, for a fourth carrier in the plurality of carriers, if the SBFD configuration information includes an activation indication and a validity indication of the fourth carrier, the activation indication is used to activate the fourth carrier, and the validity indication is used to indicate that the SBFD frequency domain resource on the fourth carrier is valid or invalid.

[0226] For example, in order to minimize the impact on legacy UEs, for the activation and deactivation of SBFD frequency domain resources, and the activation and deactivation of carriers, the following method can be used: if the base station deactivates a carrier through DCI, the SBFD configuration on the carrier is invalid. That is, the base station sends the SBFD configuration information to the UE through DCI, the SBFD configuration information includes a deactivation indication of the carrier, the deactivation indication is used to deactivate the carrier, and the deactivation indication is used to indicate that the SBFD frequency domain resource on the carrier is invalid.

[0227] When the base station activates a carrier through DCI, the DL / UL configuration on the carrier is valid, but the SBFD configuration on the carrier will not be valid, which can be indicated by 1 bit whether the SBFD configuration is valid. In this way, the base station can flexibly control whether the SBFD configuration is valid according to the characteristics and amount of users in the cell. That is, the base station sends the SBFD configuration information to the UE through DCI, the SBFD configuration information includes an activation indication of the carrier, the activation indication is used to activate the carrier. The SBFD configuration information also includes a 1-bit validity indication, if the validity indication is a first value (such as 1), it indicates that the SBFD frequency domain resource on the carrier is valid; if the validity indication is a second value (such as 0), it indicates that the SBFD frequency domain resource on the carrier is invalid.

[0228] For example, see Table 6 for an example of carrier-based SBFD configuration enabling indication (SBFD configuration information activation indication) in a multi-carrier scenario.

[0229] Table 6

[0230]

[0231] In one example, for the above-mentioned manner 3, the fifth allocation indication is used to indicate whether the offset between the second carrier and the first carrier is activated, and based on this, the SBFD configuration activation can also be implicitly indicated by the fifth allocation indication. For example, if the fifth allocation indication is used to indicate that the offset between the second carrier and the first carrier is activated, the fifth allocation indication implicitly indicates that the SBFD frequency domain resource on the second carrier is activated. If the fifth allocation indication is used to indicate that the offset between the second carrier and the first carrier is not activated, the fifth allocation indication implicitly indicates that the SBFD frequency domain resource on the second carrier is not activated.

[0232] For example, see Table 7 for an example of carrier-based ca-offset configuration activation indication (ca-offset enabling) in a multi-carrier scenario. The ca-offset configuration activation indication is used to indicate whether the offset (such as the slot offset and / or symbol offset) between the second carrier and the first carrier is activated or not, and the ca-offset configuration activation indication is used to indicate whether the SBFD frequency domain resource on the second carrier is activated or not.

[0233] Table 7

[0234]

[0235] When the ca-offset configuration activation indication is used to indicate that the offset between the second carrier and the first carrier is activated, the offset (such as the slot offset and / or symbol offset) between the second carrier and the first carrier can also be indicated. The offset (offset) for each carrier can be delivered to the UE by using the RRC message or pre-configuration, or the offset can be configured by using the DCI message. Among them, a group of offsets can be commonly used for several carriers, or an offset can be configured for each carrier.

[0236] For example, taking the offset as a slot offset, see Table 8 for an example of carrier-based ca-slotoffset configuration parameter (i.e. slot offset) in a multi-carrier scenario.

[0237] Table 8

[0238]

[0239] For the case of refSCS 15 kHz, the slot offset can be -2, -1, 0, 1, 2, -2 means left shift 2 slots, 2 means right shift 2 slots, and so on. For the case of refSCS 30 kHz, the slot offset can be -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and so on.

[0240] For example, the offset is symbol offset, see Table 9, for the case of multi-carrier, the carrier-based ca-symboloffset configuration parameter (i.e., symbol offset).

[0241] Table 9

[0242] Parameter Name Note ca-SymbolOffset INTEGER(0..13),

[0243] The symbol offset can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and the symbol offset means the number of symbols shifted to the left, or the number of symbols shifted to the right.

[0244] Sixth, for the case of multi-carrier, carrier-based SBFD frequency domain resource allocation and activation.

[0245] In one example, the base station can configure SBFD frequency domain resources in each of the plurality of carriers. The base station can transmit SBFD resource allocation information to the UE, the SBFD resource allocation information indicating the SBFD frequency domain resources configured in each carrier. In the SBFD frequency domain resources configured in each carrier, there are at least one set of opposite slots in the carrier, and the opposite slots can include uplink slots and downlink slots.

[0246] See Fig. 9 for a schematic diagram of multi-carrier-based SBFD frequency domain resource allocation. For each of the plurality of carriers, SBFD frequency domain resources can be formed in each carrier. For example, SBFD frequency domain resources can be formed in CC1, and SBFD frequency domain resources can be formed in CC2. Figure 5B In one example, before SBFD frequency domain resources are formed in each carrier, the slots in the carrier are the same. For example, the slots in the carrier are in turn DL slot, DL slot, DL slot, UL slot, UL slot.

[0247] In order to form SBFD frequency domain resources in the carrier, there are at least one set of opposite slots in the carrier. For example, see Fig. 10, for the case of multi-carrier, the carrier-based SBFD frequency domain resource allocation.

[0248] Figure 5B ​As shown, time slot 0 of CC1 is a DL slot and an UL slot, time slot 1 of CC1 is a DL slot and an UL slot, time slot 2 of CC1 is a DL slot and an UL slot, time slot 3 of CC1 is a DL slot and an UL slot, and time slot 4 of CC1 is a DL slot and an UL slot. Time slot 0 of CC2 is a DL slot and an UL slot, time slot 1 of CC2 is a DL slot and an UL slot, time slot 2 of CC2 is a DL slot and an UL slot, time slot 3 of CC2 is a DL slot and an UL slot, and time slot 4 of CC2 is a DL slot and an UL slot.

[0249] So far, the carrier-based SBFD frequency domain resource allocation is completed. The base station configures SBFD frequency domain resources in each carrier and sends SBFD resource allocation information to the UE. The UE receives the SBFD resource allocation information, and the SBFD resource allocation information is used to indicate the SBFD frequency domain resources configured in each carrier.

[0250] After the completion of the carrier-based SBFD frequency domain resource allocation, the activation and deactivation of the carrier-based SBFD frequency domain resources can also be involved. For example, for each carrier, the base station can send SBFD configuration information corresponding to the carrier to the UE. The UE receives the SBFD configuration information, and the SBFD configuration information is used to indicate that the SBFD frequency domain resources on the carrier are valid or invalid. Wherein, valid means activating the SBFD frequency domain resources on the carrier, and invalid means deactivating the SBFD frequency domain resources on the carrier.

[0251] For example, when the base station sends the SBFD configuration information to the UE, for a third carrier in the plurality of carriers, if the SBFD configuration information includes a deactivation indication of the third carrier, the deactivation indication is used to deactivate the third carrier, and the deactivation indication is used to indicate that the SBFD frequency domain resources on the third carrier are invalid.

[0252] When the base station sends the SBFD configuration information to the UE, for a fourth carrier in the plurality of carriers, if the SBFD configuration information includes an activation indication and a validity indication of the fourth carrier, the activation indication is used to activate the fourth carrier, and the validity indication is used to indicate that the SBFD frequency domain resources on the fourth carrier are valid or invalid.

[0253] For example, there is already SBFD configuration in each carrier, and the base station controls the SBFD configuration of each carrier independently. If the base station deactivates a carrier through DCI, the SBFD configuration on the carrier is invalid. If the base station activates a carrier through DCI, the DL / UL configuration on the carrier is valid, but the SBFD configuration on the carrier is not valid. A 1-bit indication can be used to indicate whether the SBFD configuration is valid. In this way, the base station can flexibly control whether the SBFD configuration is valid according to the characteristics and amount of users in the cell.

[0254] For example, the base station can send the SBFD configuration for each carrier to the UE through the RRC message. The base station can independently activate or deactivate the SBFD configuration for each carrier.

[0255] In summary, for carrier-based SBFD frequency domain resource allocation and activation, the SBFD resource parameters can be configured independently for each carrier. Then, by introducing the SBFD configuration activation / deactivation parameters in the DCI message, the base station can flexibly control the SBFD configuration on each carrier.

[0256] As can be seen from the above technical solutions, in the multi-carrier flexible BWP configuration, the flexible SBFD frequency domain resources (such as downlink frequency domain resources and uplink frequency domain resources) are configured for the UE through the BWP to support data transmission in the TDD system. The resource utilization, network coverage and network capacity are improved, the uplink transmission resources and cell coverage are increased, the uplink transmission delay is reduced and the uplink transmission capacity is increased. Without affecting the 5G system, in the multi-carrier flexible BWP configuration, the DL / UL frequency domain resources can be flexibly configured for the UE through activation and switching, to support simultaneous transmission and reception of the base station / UE in the TDD system, to increase the uplink transmission resources and cell coverage, to reduce the transmission delay and to increase the uplink transmission capacity.

[0257] Based on the same inventive concept, a resource allocation device corresponding to the above-mentioned resource allocation method, and a base station and a UE are also provided. Since the principles of the base station and the UE solving the problem are similar to those of the resource allocation method, the implementation of the base station and the UE can be referred to the implementation of the resource allocation method, and the repeated parts will not be described again.
