[0031] In TDD transmission mode, the uplink and downlink operate at the same frequency, and the uplink and downlink are time division multiplexed, and continuous transmission opportunities cannot be obtained regardless of the uplink or downlink. Considering the small transmission power of the terminal, the uplink slot allocation is small in the macro network deployment, which limits the uplink transmission opportunities and limits the transmission rate of the edge user. With the increasing requirements for the uplink speed of various services such as data collection, monitoring, and online games in the Internet of Things scenario, the uplink speed needs to be further improved, and with the proposal of service categories such as high-definition video calling and extended reality (XR), higher requirements for service delay have also been proposed. Therefore, it is necessary to further improve the uplink coverage performance of the terminal, reduce the service delay, and improve the uplink speed.

[0032] Full-duplex technology reduces transmission delay and improves spectrum efficiency by enabling same-time uplink and downlink transmission in the TDD frequency band. Currently, the main full-duplex technologies being developed include sub-band wise full duplex and full frequency fully overlapped full duplex. In sub-band full duplex technology, the next generation NodeB (gNB) can perform uplink and downlink transmission using different sub-bands at the same time, and the terminal does not need to support same-time transmission and is still a half-duplex terminal. In full frequency full duplex technology, the gNB can transmit and receive simultaneously on the same frequency resource, and the terminal can only have half-duplex capability. Full duplex technology puts higher requirements on both terminals and base stations, and the configuration method of the TDD frame structure needs to be extended and designed to support the above sub-band full duplex and full frequency full duplex technologies. In the related art, after a terminal accesses a cell, it receives a TDD-UL-DL-ConfigComm in a System Information Block (SIB) 1 message, and this configuration information is cell-specific configuration information that applies to all terminals and specifies the period length of the TDD frame structure and the uplink / downlink slot distribution within the period. For the cell-specific TDD frame structure configuration, the configured uplink / downlink transmission direction is set to start with downlink transmission within one period and end with uplink transmission, and the time domain resource not configured between the downlink and uplink is a flexible resource. In addition to the cell-specific TDD frame structure configuration, there is also a terminal-specific TDD frame structure configuration, i.e., by setting tdd-UL-DL-ConfigurationDedicated in servingcellconfig, the uplink / downlink of the flexible slot is further configured.However, the above TDD frame configuration cannot realize simultaneous uplink and downlink transmission in one TDD carrier, which limits the flexibility of the configuration and is disadvantageous to improving the delay and uplink coverage performance. If the uplink transmission and downlink transmission of the same slot can be configured, for some services with high uplink transmission needs, uplink transmission will appear in each slot, which can reduce the delay. In addition, the continuous uplink resources uplink can be used for repeated transmission to improve the uplink coverage.

[0033] Based on this, in each embodiment of the present disclosure, a terminal receives a first configuration transmitted from a base station, the first configuration includes at least one kind of first TDD uplink / downlink configuration applied to a first subband resource, and the terminal further receives a second TDD uplink / downlink configuration transmitted from the base station, the second TDD uplink / downlink configuration characterizing a cell-specific TDD uplink / downlink configuration. In this way, different TDD uplink / downlink configurations are configured in the terminal, and based on this, the base station simultaneously performs uplink transmission and downlink transmission in different subbands of one TDD carrier, thereby improving the uplink coverage performance of a user.

[0034] The present disclosure will now be described in further detail in conjunction with the accompanying drawings and examples.

[0035] First, the 5th generation mobile communication technology thThe TDD uplink-downlink configuration of the 5G (5th Generation) is described. First, the 5G uplink-downlink configuration supports more kinds of uplink-downlink switching cycles, including semi-static uplink-downlink switching cycles of 0.5ms, 1ms, 2ms, 5ms and 10ms, and further supports uplink-downlink switching cycles of 0.625ms (applied to 120kHz subcarrier spacing), 1.25ms (applied to 60kHz and 120kHz subcarrier spacing) and 2.5ms (applied to 30kHz, 60kHz and 120kHz subcarrier spacing). The terminal receives a TDD-UL-DL-ConfigComm in a SIB 1 message, and the configuration parameters include an uplink-downlink switching cycle, a reference subcarrier spacing and an uplink-downlink transmission configuration. The value of the uplink-downlink switching cycle is {0.5, 0.625, 1, 1.25, 2, 2.5, 5, 10}ms. The value of the reference subcarrier spacing is in the range of 15kHz, 30kHz or 60kHz for the frequency band below 6GHz, and is in the range of 60kHz or 120kHz for the frequency band above 6GHz. The number of slots included in each period can be determined based on the set reference subcarrier spacing and the uplink-downlink switching period, and the transmission ratio of downlink and uplink in the uplink-downlink switching period can be determined based on the uplink-downlink transmission setting. The uplink-downlink transmission setting specifically includes an uplink-downlink transmission slot setting and a symbol setting, and is indicated by four parameters uplink of x1, y1, x2 and y2. Taking FIG. 1 as an example, if the reference subcarrier spacing is 30kHz and the uplink-downlink period is 5ms, it can be determined that each period contains 10 slots.x1=3, x2=5, y1=2, y2=6, the corresponding previous three slots are all downlink slots, the last two slots are all uplink slots, the previous five symbols of slot 3 are downlink and denoted as D, the last six symbols of slot 7 are uplink and denoted as U, and the intermediate slots and symbols are flexible slots and flexible symbols and denoted as F.

[0036] In order to further improve the uplink coverage performance of the terminal, reduce the service delay, and improve the uplink speed, the embodiment of the present disclosure provides a resource configuration method for the terminal. Referring to FIG. 2, the method includes the following step 201:

[0037] In step 201, a first configuration sent from a base station is received.

[0038] The first configuration includes at least one type of first TDD uplink / downlink configuration applied to a first subband resource, and the terminal further receives a second TDD uplink / downlink configuration transmitted from the base station, the second TDD uplink / downlink configuration characterizing a cell-specific TDD uplink / downlink configuration.

[0039] As mentioned above, in the related art, after the terminal accesses the cell, the terminal can receive a cell-specific TDD uplink / downlink configuration, i.e., the second TDD uplink / downlink configuration in the SIB 1 message. On this basis, in the embodiment of the present disclosure, the base station further sends a first TDD uplink / downlink configuration to the terminal, and the first TDD uplink / downlink configuration is different from the cell-specific second TDD uplink / downlink configuration and is applied to a first subband resource. The first subband resource includes a cell-specific subband resource or a terminal-level subband resource.

[0040] In practical application, the first TDD uplink / downlink configuration and the second TDD uplink / downlink configuration may be transmitted by the base station via different configuration messages, or the first TDD uplink / downlink configuration and the second TDD uplink / downlink configuration may be encapsulated in the same configuration message and transmitted by the base station.

[0041] Considering that the Multicast and Broadcast Service (MBS) is introduced in Release 17 (R 17), the 3rd Generation Partnership Project (3GPP) defined the concept of Common Frequency Resource (CFR). The CFR corresponds to a series of contiguous Common Resource Blocks (CRB) in the BWP, and the terminal receives the broadcast service only within the frequency domain resource range defined by the CFR. Therefore, in practical application, the first TDD uplink / downlink configuration can be understood as a TDD uplink / downlink configuration at the CFR level.

[0042] In one embodiment, the step of receiving a first configuration transmitted from the base station includes: The method includes receiving the first configuration sent by the base station via a system message or RRC signaling.

[0043] The system message may include a SIB message.

[0044] In one embodiment, the terminal applies the second TDD uplink / downlink configuration for a second subband resource, which characterizes a subband resource other than the first subband resource in a cell. For example, the subband resource is a series of continuous frequency domain resources, for example, the second subband resource may be a BWP, i.e., except for the first subband resource applying the first TDD uplink / downlink configuration, the rest apply the second TDD uplink / downlink configuration in the BWP with or without resource overlap with the first subband resource. In this way, it is possible to realize that the base station simultaneously performs uplink transmission and downlink transmission in different subbands of one TDD carrier.

[0045] In practical application, the first configuration may be transmitted when the terminal first accesses the cell, or may be transmitted by the base station to the terminal in a connected state.

[0046] Before the terminal first accesses the cell, the base station configures the first TDD uplink / downlink configuration for the terminal, and thus the cell-specific TDD uplink / downlink configuration and the terminal-level TDD uplink / downlink configuration can be combined to realize the sub-band full-duplex configuration and the full same frequency full-duplex configuration of the first access stage. Illustratively, the TDD-UL-DL-ConfigCommon is configured in the SIB 1 message to obtain the cell-specific TDD uplink / downlink configuration, and the CFR and the TDD-UL-DL-CFR corresponding to the CFR are configured in the SIB message to obtain the CFR-level TDD uplink / downlink configuration.

[0047] In one embodiment, the first subband resource is located within a BWP, or the first subband resource is located outside a BWP.

[0048] The BWP may be an initial DL / UL BWP or a non-initial BWP, including a BWP set by the RRC.

[0049] Exemplarily, before the terminal first accesses the cell, the cell-specific second TDD uplink / downlink configuration configured by the base station for the terminal is "DDDFU", and the first TDD uplink / downlink configuration configured by the base station for the terminal is "UUUUU", where "D" represents downlink resource, "U" represents uplink resource, and "F" represents flexible resource. With reference to the configuration scheme shown in FIG. 3, the first subband resource is located within the initial uplink / downlink BWP (initial DL / UL BWP), and the initial uplink / downlink BWP applies the cell-specific TDD uplink / downlink configuration, and the first subband resource applies the first TDD uplink / downlink configuration, so that in the same slot, different transmission directions appear at different frequency domain positions, such as the first three slots, where the first subband resource is uplink transmission, and other resources of the initial uplink / downlink BWP other than the first subband resource are downlink transmission. With reference to the configuration scheme shown in FIG. 4, the first subband resource is located outside the initial DL / UL BWP. The above configuration method can reduce the time that a terminal waits for an uplink slot and improve the random access speed.

[0050] In one embodiment, the first configuration is used to configure the first subband resource as all uplink transmission. That is, the first configuration includes at least one type of first TDD uplink / downlink configuration applied to the first subband resource, the first configuration can refer to a configuration for the transmission direction of the first subband resource, specifically, the first subband resource is configured as all uplink transmission, that is, the all uplink transmission configuration can be understood as a presentation form of the TDD uplink / downlink configuration applied to the first subband resource. In addition, when the TDD uplink / downlink is configured to a specific configuration, it is not limited to being reflected as TDD configuration signaling, and can refer to the provision of resource uplink and downlink transmission directions in a TDD system, for example, all uplink transmission is a provision of the transmission direction of the first subband resource in a TDD system.

[0051] In one embodiment, the first subband resource and the frequency domain resource of the first BWP overlap.

[0052] In addition, the first subband resource may be located within the first BWP, may be located outside the first BWP, or may completely overlap with the first BWP, thereby realizing a configuration that supports simultaneous same-frequency uplink and downlink transmission.

[0053] Referring to the example of Figure 5, the second TDD uplink / downlink setting set by the base station for the terminal is "DDDFU", the first TDD uplink / downlink setting set by the base station for the terminal is "UUUUD", and full simultaneous co-frequency full duplexing can be realized by setting the first subband resource to be the same as the bandwidth of the initial BWP.

[0054] As mentioned above, only the configuration manner in which the TDD uplink / downlink configuration in one period starts with downlink transmission and ends with uplink transmission, i.e., the start of the TDD uplink / downlink configuration is "D" and the end is "U", therefore, in practical application, when the TDD uplink / downlink configuration has uplink resources and downlink resources at the same time, it is also necessary to introduce a slot offset. Based on this, in one embodiment, the first configuration further includes a slot offset value, which characterizes a slot offset of a period start position of the first TDD uplink / downlink configuration relative to a period start position of the second TDD uplink / downlink configuration.

[0055] For example, the second TDD uplink / downlink configuration configured for the terminal by the base station is "DUUUU", then configure one slot offset value 4, thus the start position of the second TDD uplink / downlink configuration period is shifted four slots backward with respect to the start position of the first TDD uplink / downlink configuration period. When the first TDD uplink / downlink configuration is configured as "DDFUU", the period start slot D of the first TDD uplink / downlink configuration is aligned with the fourth slot U in the second TDD uplink / downlink configuration period.

[0056] Further, referring to the example of FIG. 6, before the terminal first accesses the cell, the second TDD uplink / downlink configuration configured for the terminal by the base station is “DFFFU”, the first TDD uplink / downlink configuration configured for the terminal by the base station is “FFFFU”, and the first subband resource is located in the initial DL / UL BWP. In this case, since the second TDD uplink / downlink configuration uses a flexible slot configuration, there is no need to additionally configure a slot offset value, and it can be realized that the first slot of the TDD uplink / downlink configuration period of the initial BWP is downlink transmission, and the flexible slot in the first subband resource schedules uplink transmission in the manner of base station scheduling.

[0057] In one embodiment, the first configuration further includes at least one first BWP associated with the first subband resource, and when the activated BWP of the terminal is a first BWP, the terminal applies the first TDD uplink-downlink configuration for the first subband resource and applies the second TDD uplink-downlink configuration for the first BWP.

[0058] For example, for one first subband resource, two first BWPs are configured, each of which is a first BWP A and a first BWP B. Since the terminal can only activate one BWP at the same time, when the terminal's activated BWP is A, the terminal simultaneously applies the second TDD uplink downlink configuration for BWP A and applies the first TDD uplink downlink configuration for the first subband resource. When the terminal's activated BWP is B, the terminal simultaneously applies the second TDD uplink downlink configuration for BWP B and applies the first TDD uplink downlink configuration for the first subband resource. Furthermore, for a case where a plurality of first subband resources are configured, referring to the example of FIG. 7, a case where two first subband resources are configured is illustrated, which respectively correspond to the first subband resources C and D. Taking the terminal as an example in a connected state, for the first BWP, the first TDD uplink-downlink setting of the first subband resource C only has downlink resources, i.e., "DDDDD", and the first TDD uplink-downlink setting of the first subband resource D only has uplink resources, i.e., "UUUUU", when the activated BWP of the terminal is the first BWP, the terminal applies the first TDD uplink-downlink setting "DDDDD" for the first subband resource C, applies the first TDD uplink-downlink setting "UUUUU" for the first subband resource D, and applies the second TDD uplink-downlink setting for the first BWP.

[0059] In practical application, such a setting can support not only terminals that cannot transmit and receive simultaneously, but also terminals that can transmit and receive simultaneously. For terminals that cannot transmit and receive simultaneously, it is determined whether to operate in the uplink resource part or the downlink resource part in the current slot according to the base station's scheduling. Furthermore, terminals that cannot transmit and receive simultaneously do not need to recognize the CFR, and in order to serve the base station's scheduling, if the resources of the CFR part need to avoid interference with terminals in this part, a rate matching mode (rate match pattern) can be set to avoid interference in the uplink part.

[0060] In contrast to the resource configuration method applied to the terminal side in the embodiment of the present disclosure, the embodiment of the present disclosure further provides a resource configuration method applied to the base station. As shown in FIG. 8, the method includes the following step 801:

[0061] In step 801, a first configuration is sent to the terminal.

[0062] The first configuration includes at least one first TDD uplink / downlink configuration to be applied to a first subband resource. The base station further transmits a second TDD uplink / downlink configuration to the terminal, the second TDD uplink / downlink configuration characterizing a cell-specific TDD uplink / downlink configuration.

[0063] As mentioned above, in the related art, after the terminal accesses the cell, the terminal can receive a cell-specific TDD uplink / downlink configuration, i.e., the second TDD uplink / downlink configuration in the SIB 1 message. Based on this, in the embodiment of the present disclosure, the base station also sends a first TDD uplink / downlink configuration to the terminal, and the first TDD uplink / downlink configuration is different from the cell-specific second TDD uplink / downlink configuration and is applied to a first subband resource. The first subband resource includes a cell-specific subband resource or a terminal-level subband resource.

[0064] In practical application, the first TDD uplink / downlink configuration and the second TDD uplink / downlink configuration may be transmitted by the base station via different configuration messages, or the first TDD uplink / downlink configuration and the second TDD uplink / downlink configuration may be encapsulated in the same configuration message and transmitted by the base station.

[0065] In one embodiment, the terminal applies the second TDD uplink / downlink configuration for a second subband resource, which characterizes a subband resource other than the first subband resource in a cell. For example, the subband resource is a series of continuous frequency domain resources, for example, the second subband resource may be a BWP, i.e., except for the first subband resource applying the first TDD uplink / downlink configuration, the rest apply the second TDD uplink / downlink configuration in the BWP with or without resource overlap with the first subband resource. In this way, it is possible to realize that the base station simultaneously performs uplink transmission and downlink transmission in different subbands of one TDD carrier.

[0066] In practical application, the first configuration may be transmitted when the terminal first accesses the cell, or may be transmitted by the base station to the terminal in a connected state.

[0067] Before the terminal first accesses the cell, the base station configures a first TDD uplink / downlink configuration for the terminal, and in this way, the cell-specific TDD frame uplink / downlink configuration and the terminal-level TDD uplink / downlink configuration can be combined to realize the sub-band full-duplex configuration and the full same-frequency full-duplex configuration of the first access phase.

[0068] In one embodiment, the first subband resource includes a cell-specific subband resource or a terminal-level subband resource.

[0069] In one embodiment, the first subband resource is located within a BWP, or the first subband resource is located outside a BWP.

[0070] The BWP may be an initial DL / UL BWP or a non-initial BWP, including a BWP set by the RRC.

[0071] In one embodiment, the first configuration further includes a slot offset value, the slot offset value characterizing a slot offset of a period start position of the first TDD uplink / downlink configuration relative to a period start position of the second TDD uplink / downlink configuration.

[0072] In one embodiment, the step of transmitting a first configuration to the terminal includes: The method includes sending the first configuration to the terminal via a system message or RRC signaling.

[0073] The system message may include a SIB message.

[0074] In one embodiment, the first configuration further includes at least one first BWP associated with the first subband resource; If the activated BWP of the terminal is a first BWP, the terminal applies the first TDD uplink / downlink configuration for the first subband resource and applies the second TDD uplink / downlink configuration for the first BWP.

[0075] As mentioned above, the TDD uplink / downlink configuration in one period is only configured with downlink transmission as the start and uplink transmission as the end, i.e., the TDD uplink / downlink configuration starts with "D" and ends with "U", so in practical application, if the TDD uplink / downlink configuration has uplink resources and downlink resources at the same time, it is also necessary to introduce a slot offset.
