[0031] In TDD transmission mode, the uplink and downlink operate on the same frequency and are time-division multiplexed, making it impossible to obtain continuous transmission opportunities for either the uplink or downlink. Given the low transmit power of terminals, macro network deployments allocate fewer uplink slots, limiting uplink transmission opportunities and limiting edge user transmission rates. With the increasing requirements for uplink speeds for various services in Internet of Things scenarios, such as data collection, surveillance, and online gaming, uplink speeds must be further improved. Furthermore, with the introduction of service categories such as high-definition video calling and extended reality (XR), higher requirements for service latency have also been proposed. Therefore, it is necessary to further improve the uplink coverage performance of terminals, reduce service latency, and increase uplink speeds.

[0032] Full-duplex technology reduces transmission latency and improves spectral efficiency by enabling co-time uplink and downlink transmissions in the TDD frequency band. The currently developed full-duplex technologies include sub-band full duplex and full-frequency overlapped full duplex. With sub-band full duplex, the next-generation NodeB (gNB) can transmit uplink and downlink signals at the same time using different sub-bands. Terminals do not need to support co-time transmission and are still half-duplex. With full-frequency overlapped full duplex, the gNB can transmit and receive simultaneously using the same frequency resource, while terminals can only perform half-duplex operations. Full-duplex technology places higher requirements on both terminals and base stations. To support the above sub-band full duplex and full-frequency overlapped full duplex technologies, the TDD frame structure configuration method needs to be extended. 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. This configuration information is cell-specific configuration information that applies to all terminals and specifies the length of the TDD frame structure cycle and the uplink and downlink slot distribution within the cycle. For the cell-specific TDD frame structure configuration, the configured uplink and downlink transmission direction within a cycle is downlink transmission starting and uplink transmission ending, and any 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. That is, by setting tdd-UL-DL-ConfigurationDedicated in servingcellconfig, the uplink and downlink of flexible slots are further configured.However, the above TDD frame configuration cannot realize simultaneous uplink and downlink transmission within one TDD carrier, which limits the configuration flexibility and is disadvantageous to improving latency and uplink coverage performance. If uplink transmission and downlink transmission can be configured in the same slot, uplink transmission can occur in each slot for some services with high uplink transmission needs, thereby reducing latency. In addition, repeated transmission using consecutive uplink resources can be performed to improve 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 including at least one 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 on different subbands of one TDD carrier, thereby improving the uplink coverage performance of a user.

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

[0035] First, the 5th generation mobile communication technology thThis section describes the TDD uplink and downlink configuration for 5G (5th Generation). First, the 5G uplink and downlink configuration supports more uplink and downlink switching cycles, including semi-static uplink and downlink switching cycles of 0.5 ms, 1 ms, 2 ms, 5 ms, and 10 ms, and further supports uplink and downlink switching cycles of 0.625 ms (applicable to 120 kHz subcarrier spacing), 1.25 ms (applicable to 60 kHz and 120 kHz subcarrier spacing), and 2.5 ms (applicable to 30 kHz, 60 kHz, and 120 kHz subcarrier spacing). The terminal receives a TDD-UL-DL-ConfigComm in an SIB 1 message, and the configuration parameters include the uplink and downlink switching cycle, the reference subcarrier spacing, and the uplink and downlink transmission configuration. The values ​​of the uplink and downlink switching cycle are {0.5, 0.625, 1, 1.25, 2, 2.5, 5, 10} ms. The value of the reference subcarrier spacing ranges from 15 kHz, 30 kHz, or 60 kHz for frequency bands below 6 GHz, and from 60 kHz or 120 kHz for frequency bands above 6 GHz. The number of slots included in each period can be determined based on the set reference subcarrier spacing and the uplink / downlink switching period. Furthermore, the ratio of downlink and uplink transmission within the uplink / downlink switching period can be determined based on the uplink / downlink transmission configuration. The uplink / downlink transmission configuration specifically includes an uplink / downlink transmission slot configuration and a symbol configuration, and is indicated by four uplink parameters: x1, y1, x2, and y2. Taking FIG. 1 as an example, if the reference subcarrier spacing is 30 kHz and the uplink / downlink period is 5 ms, 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 are represented as D, the last six symbols of slot 7 are uplink and are represented as U, and the intermediate slots and symbols are flexible slots and flexible symbols and are represented as F.

[0036] In order to further improve the uplink coverage performance of the terminal, reduce service delay, and increase the uplink speed, the embodiment of the present disclosure provides a resource configuration method for the terminal. Referring to Figure 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 a terminal accesses a cell, the terminal can receive a cell-specific TDD uplink / downlink configuration, i.e., a second TDD uplink / downlink configuration, in the SIB 1 message. Based on this, in an embodiment of the present disclosure, the base station further sends a first TDD uplink / downlink configuration to the terminal, where 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 the introduction of Multicast and Broadcast Service (MBS) in Release 17 (R17), the 3rd Generation Partnership Project (3GPP®) defined the concept of Common Frequency Resource (CFR). CFR corresponds to a series of contiguous Common Resource Blocks (CRB) within a BWP, and a terminal receives broadcast services 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 comprises: 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 may be a series of continuous frequency domain resources, for example, the second subband resource may be a BWP, i.e., the first subband resource applies the first TDD uplink / downlink configuration, and the remaining subband resources apply the second TDD uplink / downlink configuration in a BWP with or without resource overlap with the first subband resource. In this way, it is possible for a base station to simultaneously perform uplink transmission and downlink transmission on 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 a 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 subband full-duplex configuration and fully same-frequency full-duplex configuration in the initial access phase. For example, a TDD-UL-DL-ConfigCommon is configured in the SIB 1 message to obtain the cell-specific TDD uplink / downlink configuration, and a CFR and a 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] For example, before the terminal first accesses the cell, the cell-specific second TDD uplink / downlink configuration configured for the terminal by the base station is "DDDFU," and the first TDD uplink / downlink configuration configured for the terminal by the base station is "UUUUU," where "D" represents downlink resource, "U" represents uplink resource, and "F" represents flexible resource. Referring to the configuration scheme shown in FIG. 3, the first subband resource is located within the initial uplink / downlink BWP (initial DL / UL BWP). 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. Therefore, different transmission directions appear at different frequency domain positions in the same slot. For example, the first subband resource is for uplink transmission, and the other resources of the initial uplink / downlink BWP other than the first subband resource are for downlink transmission. Referring to the configuration scheme shown in FIG. 4, the first subband resource is located outside the initial DL / UL BWP. The above setting 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 first TDD uplink / downlink configuration applied to the first subband resource, which may refer to a configuration for the transmission direction of the first subband resource, specifically, configuring the first subband resource as all uplink transmission. That is, this all uplink transmission configuration may be understood as a representation of the TDD uplink / downlink configuration applied to the first subband resource. Note that when TDD uplink / downlink is configured as a specific configuration, it is not limited to being reflected as TDD configuration signaling, and may refer to a specification of resource uplink and downlink transmission directions in a TDD system, for example, all uplink transmission is a specification 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 configuration set by the base station for the terminal is "DDDFU", and the first TDD uplink / downlink configuration set by the base station for the terminal is "UUUUD", and by setting the first subband resource to be the same as the bandwidth of the initial BWP, complete simultaneous co-frequency full duplexing can be achieved.

[0054] As mentioned above, only the TDD uplink / downlink configuration within one period is 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". Therefore, in practical application, if uplink resources and downlink resources coexist in the TDD uplink / downlink configuration, it is necessary to introduce a slot offset. Based on this, in one embodiment, the first configuration further includes a slot offset value, which characterizes the slot offset of the period start position of the first TDD uplink / downlink configuration relative to the period start position of the second TDD uplink / downlink configuration.

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

[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 within the initial DL / UL BWP. In this case, since the second TDD uplink / downlink configuration uses flexible slot configuration, there is no need to additionally configure a slot offset value. It is possible to realize that the first slot of the TDD uplink / downlink configuration period of the initial BWP is downlink transmission, and the flexible slot within the first subband resource schedules uplink transmission in a base station scheduling manner.

[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 the 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, two first BWPs are configured for one first subband resource, namely, first BWP A and first BWP B. Since a terminal can only activate one BWP at a time, when the activated BWP of the terminal is A, the terminal simultaneously applies a second TDD uplink / downlink configuration for BWP A and a first TDD uplink / downlink configuration for the first subband resource. When the activated BWP of the terminal is B, the terminal simultaneously applies a second TDD uplink / downlink configuration for BWP B and a first TDD uplink / downlink configuration for the first subband resource. Furthermore, with respect to a case where multiple first subband resources are configured, referring to the example of FIG. 7, a case where two first subband resources are configured is illustrated, corresponding to first subband resources C and D, respectively. Taking the terminal as an example in a connected state, for the first BWP, the first TDD uplink-downlink configuration of the first subband resource C only has downlink resources, i.e., "DDDDD", and the first TDD uplink-downlink configuration 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 configuration "DDDDD" for the first subband resource C, applies the first TDD uplink-downlink configuration "UUUUU" for the first subband resource D, and applies the second TDD uplink-downlink configuration for the first BWP.

[0059] In practical application, this 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 portion or the downlink resource portion 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 if the resources in the CFR portion need to avoid interference with terminals in this portion due to serving the base station's scheduling, a rate match mode can be set to avoid interference in the uplink portion.

[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 Figure 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 type of first TDD uplink / downlink configuration to be applied to a first subband resource, and 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 a terminal accesses a cell, the terminal can receive a cell-specific TDD uplink / downlink configuration, i.e., a second TDD uplink / downlink configuration, in the SIB 1 message. Based on this, in an embodiment of the present disclosure, the base station also sends a first TDD uplink / downlink configuration to the terminal, where 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 may be a series of continuous frequency domain resources, for example, the second subband resource may be a BWP, i.e., the first subband resource applies the first TDD uplink / downlink configuration, and the remaining subband resources apply the second TDD uplink / downlink configuration in a BWP with or without resource overlap with the first subband resource. In this way, it is possible for a base station to simultaneously perform uplink transmission and downlink transmission on 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 in the initial 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 comprises: 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 within one period is configured with downlink transmission as the start and uplink transmission as the end, i.e., the TDD uplink / downlink configuration only starts with "D" and ends with "U", so in actual application, if uplink resources and downlink resources coexist in the TDD uplink / downlink configuration, a slot offset needs to be introduced.
