[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to a method and apparatus for determining configuration, a terminal device, and a network device. Background Art

[0002] Subband Full Duplex (SBFD) is a new duplex standard that implements full-duplex operation by dividing the same carrier into uplink and downlink subbands, and performing uplink and downlink transmissions on the uplink and downlink subbands respectively.

However, in mobile communication systems, multi-carrier technology has been introduced to improve system communication performance. The challenge of implementing sub-band full-duplex and / or non-sub-band full-duplex in multi-carrier systems is to address this issue.

[0066] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0067] 1. Uplink subband of downlink time domain unit

[0068] SBFD, also known as X-Division Duplex (XDD), is a new duplex standard that achieves full-duplex operation by dividing the same carrier into non-overlapping uplink and downlink subbands, and performing uplink and downlink transmissions on the uplink and downlink subbands respectively. In some schemes, SBFD can be achieved by dividing the uplink and downlink subbands on the downlink time domain unit or flexible time domain unit within the same time division duplex (TDD) carrier. In SBFD, because the frequency domain resources corresponding to the same downlink time domain unit or flexible time domain unit include uplink and downlink subbands, simultaneous downlink and uplink transmissions can be achieved on different subbands of the same downlink time domain unit or flexible time domain unit. SBFD is primarily used on the network equipment side. Specifically, network equipment can simultaneously perform downlink transmission and uplink reception on different subbands of the same downlink time domain unit or flexible time domain unit. The terminal equipment side still uses TDD, that is, only downlink reception or uplink transmission is supported within the same time domain unit.

[0069] In some embodiments, as shown in FIG2 , in TDD, all frequency domain resources corresponding to the downlink time domain unit are used for downlink transmission; whereas in SBFD, the frequency domain resources corresponding to the downlink time domain unit or the flexible time domain unit are divided into uplink subbands and downlink subbands, wherein the uplink subbands are used for uplink transmission and the downlink subbands are used for downlink transmission.

[0070] The time domain unit in TDD can be called a non-SBFD time domain unit (or a conventional time domain unit), and the time domain unit in TDD can be a downlink time domain unit, such as a downlink symbol or a downlink sub-time slot or a downlink time slot or a downlink subframe, and the frequency domain resources corresponding to the downlink time domain unit all belong to downlink resources. The time domain unit in TDD can also be an uplink time domain unit, such as an uplink symbol or an uplink sub-time slot or an uplink time slot or an uplink subframe, and the frequency domain resources corresponding to the uplink time domain unit all belong to uplink resources. The time domain unit in TDD can also be a flexible time domain unit, such as a flexible symbol or a flexible sub-time slot or a flexible time slot or a flexible subframe, and the frequency domain resources corresponding to the flexible time domain unit can be flexibly set as a downlink resource or an uplink resource. It should be noted that, unless otherwise specified, the non-SBFD time domain unit described below refers to the downlink time domain unit and / or flexible time domain unit in TDD.

[0071] The time domain unit in SBFD can be called an SBFD time domain unit, such as an SBFD symbol or an SBFD sub-time slot or an SBFD time slot or an SBFD subframe. In some cases, the SBFD time domain unit can also be described as a downlink time domain unit, such as a downlink symbol or a downlink sub-time slot or a downlink time slot or a downlink subframe, but it should be clarified that the frequency domain resources corresponding to the downlink time domain unit are divided into uplink subbands and downlink subbands. In some cases, the SBFD time domain unit can also be described as a flexible time domain unit, such as a flexible symbol or a flexible sub-time slot or a flexible time slot or a flexible subframe, but it should be clarified that the frequency domain resources corresponding to the flexible time domain unit are divided into uplink subbands and downlink subbands. Among them, the distribution of uplink subbands and downlink subbands in the frequency domain can have multiple ways. As an implementation method: an uplink subband is located in the middle of two downlink subbands.

[0072] In a single-carrier system, the configurations on the non-SBFD time domain unit and the SBFD time domain unit are different. The configuration on the non-SBFD time domain unit can be called the configuration corresponding to non-subband full-duplex (or conventional configuration), and the configuration on the SBFD time domain unit can be called the configuration corresponding to subband full-duplex (or subband full-duplex-specific configuration, or SBFD time domain unit-specific configuration). The above configurations include: power domain configuration, spatial domain configuration, channel state information (CSI) reporting configuration, etc. Among them, the power domain configuration can specifically be an uplink power configuration, and the spatial domain configuration can be a beam / spatial relation configuration. In addition, since the transmission direction on the non-SBFD time domain unit is downlink or uplink, and the transmission direction on the SBFD time domain unit is both downlink and uplink, a guard period is required between the non-SBFD time domain unit and the SBFD time domain unit to achieve uplink and downlink transmission switching.

[0073] 2. Uplink power control (abbreviated as uplink power control)

[0074] The uplink power control pointer controls the transmit power of the uplink signal (referred to as uplink transmit power) with the aim of ensuring that the received power of the uplink signal on the network device side meets the demodulation requirements while not interfering with other cells. Uplink power control includes open-loop power control and closed-loop power control. Open-loop power control mainly assists the terminal device in determining the uplink transmit power by configuring the target receive power and path loss compensation. Closed-loop power control mainly assists the terminal device in adjusting the uplink transmit power by configuring the power adjustment amount in real time. Examples of uplink signals that require uplink power control include: Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), Physical Uplink Control Channel (PUCCH), etc.

[0075] 3. Multi-antenna technology

[0076] Multi-antenna technologies include spatial multiplexing, spatial diversity, beamforming, and precoding. Specific features are as follows:

[0077] Spatial multiplexing and spatial diversity

[0078] Multiple-Input Multiple-Output (MIMO) technology includes spatial multiplexing and spatial diversity. Spatial multiplexing can exponentially increase the information transmission rate without increasing bandwidth, thereby significantly improving spectrum utilization. At the transmitter, a high-rate data stream is split into multiple lower-rate sub-streams, which are transmitted from different transmit antennas within the same frequency band. If the spatial subchannels formed between the antenna arrays at the transmitter and receiver are sufficiently distinct, providing an additional spatial dimension beyond the time and frequency domains, the signals transmitted from different transmit antennas can be distinguished from each other. Therefore, the receiver can distinguish these parallel sub-streams without expending additional time and frequency resources. Spatial multiplexing can significantly increase channel capacity under high signal-to-noise ratio conditions and can be used in "open-loop" conditions, where the transmitter cannot obtain channel information. Spatial diversity utilizes the multiple transmission paths provided by multiple antennas at the transmitter or receiver to transmit the same information, thereby enhancing transmission quality.

[0079] Beamforming

[0080] Beamforming technology uses multiple antennas to generate a directional beam, concentrating energy in the desired transmission direction, improving signal quality and reducing interference with other signals. Beamforming can be combined with cell splitting and cell clustering, and applied in conjunction with millimeter-wave high-frequency bands in wireless short-distance transmission systems. This concentrates signal strength in a specific direction and for a specific user group, enabling reliable and high-speed signal transmission.

[0081] Precoding

[0082] Precoding technology primarily improves performance by modifying channel characteristics. Precoding preprocesses the transmitted signal, essentially matching it to the channel. For example, in the downlink, precoding involves network equipment obtaining CSI and then calculating a precoding matrix to preprocess the transmitted signal. This allows for better matching to the channel state, reducing or even eliminating inter-signal interference, improving transmission link stability, and increasing channel capacity.

[0083] 4. CSI feedback technology

[0084] CSI feedback technology allows a terminal device to provide downlink channel CSI feedback to a network device, enabling the network device to select an appropriate modulation and coding scheme (MCS) for downlink transmission, thereby reducing the downlink block error rate (BLER). CSI includes channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), SS / PBCH block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), and layer 1 reference signal received power (L1-RSRP). The time-frequency domain resources required for CSI transmission are controlled by the network device. Among them, CQI, PMI, CRI, SSBR, LI, RI, and L1-RSRP are closely related to the number of transmitting antennas and transmit power of the network device. Therefore, when the transmitting antennas and / or transmit power of the network device change, the terminal device needs to provide corresponding CSI feedback.

[0085] 5. Switching interval

[0086] It takes time for a communication device to switch between transmitting and receiving signals. To prevent overlap, a guard interval (also known as a switching interval) is typically required between the two. During this guard interval, the communication device switches from transmitting to receiving, or vice versa. For network devices, transmitting signals corresponds to downlink transmission, and receiving signals to uplink reception. For terminal devices, transmitting signals corresponds to uplink transmission, and receiving signals to downlink reception.

[0087] Here, downlink transmission / reception refers to the transmission / reception of downlink signals or downlink channels, which can be collectively referred to as downlink transmission. Uplink transmission / reception refers to the transmission / reception of uplink signals or uplink channels, which can be collectively referred to as uplink transmission.

[0088] In mobile communication systems, multi-carrier technology has been introduced to improve system communication performance. However, the above-mentioned related technologies only clarify the application of sub-band full-duplex in single-carrier systems, but do not clarify the application of sub-band full-duplex in multi-carrier systems. To this end, the following technical solutions of the embodiments of the present application are proposed. The technical solutions of the embodiments of the present application clarify the application of sub-band full-duplex in multi-carrier systems, enabling sub-band full-duplex to be applied more widely.

[0089] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0090] In a single-carrier sub-band full-duplex system, one carrier is divided into an uplink sub-band and a downlink sub-band. Since the uplink sub-band and the downlink sub-band have different transmission directions, there is uplink and downlink cross interference between the uplink sub-band and the downlink sub-band.

[0091] To reduce interference between sub-bands, an RF filter can be set on the network device side. As shown in Figure 3, an uplink RF filter is set for carrier 1. The uplink RF filter corresponds to the uplink reception of the network device and is used to implement uplink RF filtering. Specifically, the network device can use the uplink RF filter to perform uplink RF filtering on carrier 1, thereby filtering out the uplink sub-band portion from carrier 1. The bandwidth of the uplink RF filter is the same as the bandwidth of the uplink sub-band. For example, if the bandwidth of the uplink sub-band is bandwidth 1, the bandwidth of the uplink RF filter is also bandwidth 1. In this way, the uplink sub-band portion with a bandwidth of 1 can be filtered out from carrier 1 through uplink RF filtering; through uplink RF filtering, uplink and downlink cross interference can be reduced. In addition, a downlink RF filter can also be set for carrier 1. The downlink RF filter corresponds to the downlink transmission of the network device and is used to implement downlink RF filtering. Specifically, the network device can use the downlink RF filter to send the entire carrier. The bandwidth of the downlink RF filter is the same as the bandwidth of the carrier.

[0092] To reduce interference between subbands, transmit and receive antenna isolation can also be used. This means that the network device uses different antennas for downlink transmission and uplink reception, and the antennas used for downlink transmission and uplink reception maintain a certain distance between them. This can reduce cross-interference between uplink and downlink. As shown in Figure 4, in the antenna system configured with a non-SBFD time domain unit (or conventional time domain unit), all four antennas of the network device are used for downlink transmission or uplink reception (i.e., Tx / Rx in Figure 4). In the antenna system configured with an SBFD time domain unit, to reduce cross-interference between uplink and downlink, the four antennas of the network device are divided into two groups: one for downlink transmission (i.e., Tx in Figure 4) and the other for uplink reception (i.e., Rx in Figure 4). A group of antennas used for downlink transmission in a network device can be called a downlink antenna system. The downlink antenna system includes one or more downlink transmitting antennas. As shown in Figure 4, the downlink antenna system includes two downlink transmitting antennas (i.e., Tx in Figure 4); a group of antennas used for uplink reception in a network device can be called an uplink antenna system. The uplink antenna system includes one or more uplink receiving antennas. As shown in Figure 4, the uplink antenna system includes two uplink receiving antennas (i.e., Rx in Figure 4).

[0093] In a multi-carrier system, multiple carriers are used for communication between terminal devices and network equipment.

[0094] In some embodiments, each of the multiple carriers corresponds to an independent uplink RF filter and an independent uplink antenna system. Specifically, each of the multiple carriers corresponds to an independent uplink RF filter and an independent uplink antenna system on the network device side. In some embodiments, this mode of multiple carriers can be referred to as a first mode, where each of the multiple carriers corresponds to an independent uplink RF filter and an independent uplink antenna system on the network device side.

[0095] In some embodiments, the multiple carriers correspond to a unified downlink RF filter and a unified downlink antenna system on the network device side. In other embodiments, each of the multiple carriers corresponds to an independent downlink RF filter and an independent downlink antenna system on the network device side.

[0096] For the first mode, the network device requires multiple uplink RF filters and uplink antenna systems, each corresponding to a single carrier. The uplink antenna system is used by the network device to receive the carrier, and the uplink RF filter is used by the network device to filter out the uplink subband portion of the received carrier. Each of the multiple carriers can be independently configured with an uplink subband. Uplink subbands can be configured for some, all, or none of the multiple carriers.

[0097] In some embodiments, as shown in Figure 5, multiple carriers include carrier 1, carrier 2 and carrier 3. These three carriers correspond to independent uplink RF filters and independent uplink antenna systems, respectively. Carrier 1 corresponds to uplink RF filter 1 and uplink antenna system 1, carrier 2 corresponds to uplink RF filter 2 and uplink antenna system 2, and carrier 3 corresponds to uplink RF filter 3 and uplink antenna system 3; each of the three carriers can be independently configured with an uplink subband. In Figure 5, an uplink subband is configured on carrier 1, an uplink subband is configured on carrier 2, and an uplink subband is not configured on carrier 3. The corresponding uplink RF filtering can be performed on carrier 1 through the uplink RF filter 1 corresponding to carrier 1, and the corresponding uplink RF filtering can be performed on carrier 2 through the uplink RF filter 2 corresponding to carrier 2.

[0098] In the first mode, if the carrier corresponding to a time domain unit (the time domain unit is a downlink time domain unit or a flexible time domain unit) is configured with an uplink subband, then the time domain unit is a first type of time domain unit, and the first type of time domain unit may be an SBFD time domain unit, such as an SBFD symbol or an SBFD sub-time slot or an SBFD time slot or an SBFD subframe. If the carrier corresponding to a time domain unit (the time domain unit is a downlink time domain unit or a flexible time domain unit) is not configured with an uplink subband, then the time domain unit is a second type of time domain unit, and the second type of time domain unit may be a non-SBFD time domain unit (or a conventional time domain unit), such as a non-SBFD symbol or a non-SBFD sub-time slot or a non-SBFD time slot or a non-SBFD subframe. It can be understood that an uplink subband is configured on the carrier corresponding to the SBFD time domain unit, while an uplink subband is not configured on the carrier corresponding to the non-SBFD time domain unit.

[0099] In other embodiments, multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system. Specifically, multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network device side. In some embodiments, this multiple carrier mode can be referred to as a second mode, where the multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network device side.

[0100] In some embodiments, the multiple carriers correspond to a unified downlink RF filter and a unified downlink antenna system on the network device side. In other embodiments, each of the multiple carriers corresponds to an independent downlink RF filter and an independent downlink antenna system on the network device side.

[0101] For the second mode, the network equipment only needs to have one set of uplink RF filters and uplink antenna systems, and the hardware cost of the equipment is relatively low. One set of uplink RF filters and uplink antenna systems corresponds to multiple carriers. The uplink antenna system is used to receive multiple carriers, and the uplink RF filters are used to filter out the uplink sub-band portion from the multiple carriers. Here, the multiple carriers corresponding to one set of uplink RF filters and uplink antenna systems can be referred to as a band combination. Within the band combination, only one carrier is configured with an uplink sub-band, or more than one carrier may be configured with an uplink sub-band but the carriers configured with the uplink sub-bands are continuous. From another perspective, an uplink sub-band is configured within the band combination, and the uplink sub-band is located within one carrier or within multiple continuous carriers. The bandwidth of the uplink RF filter is the bandwidth of the uplink sub-band.

[0102] It should be noted that "contiguous carriers" means that there are no frequency domain resources used for transmission between carriers, especially frequency domain resources for different transmission directions. Carriers can also be considered contiguous if there are guard intervals between carriers or gaps reserved by operators when allocating carriers.

[0103] In some embodiments, as shown in Figure 6, multiple carriers include carrier 1, carrier 2, and carrier 3. These three carriers correspond to (or share) a unified uplink RF filter and a unified uplink antenna system; these three carriers constitute a band combination. If only one carrier in the band combination is configured with an uplink subband, such as carrier 2 in the left figure, uplink RF filtering can be performed on carrier 2 using a unified uplink RF filter. Alternatively, if more than one (e.g., three) carriers in the band combination are configured with an uplink subband but the carriers configured with uplink subbands are continuous, uplink RF filtering can be performed on carriers 1, 2, and 3 using a unified uplink RF filter.

[0104] In the second mode, if the band combination corresponding to a time domain unit (the time domain unit is a downlink time domain unit or a flexible time domain unit) is configured with an uplink subband, then the time domain unit is a first type of time domain unit, and the first type of time domain unit can be an SBFD time domain unit, such as an SBFD symbol or an SBFD subslot or an SBFD time slot or an SBFD subframe. If the band combination corresponding to a time domain unit (the time domain unit is a downlink time domain unit or a flexible time domain unit) is not configured with an uplink subband, then the time domain unit is a second type of time domain unit, and the second type of time domain unit can be a non-SBFD time domain unit (or a conventional time domain unit), such as a non-SBFD symbol or a non-SBFD subslot or a non-SBFD time slot or a non-SBFD subframe. It can be understood that the band combination corresponding to the SBFD time domain unit is configured with an uplink subband, while the band combination corresponding to the non-SBFD time domain unit is not configured with an uplink subband.

[0105] It should be noted that the time domain unit described in the embodiments of the present application may be a subframe, a time slot, a sub-time slot, or a symbol.

[0106] It should be noted that the subband described in the embodiments of the present application is composed of multiple frequency domain units, and the frequency domain units are, for example, resource blocks (RBs) or physical resource blocks (PRBs) or resource block groups (RBGs) or physical resource block groups (PRGs), etc.

[0107] It should be noted that for more understanding of the first type of time domain unit and the second time domain unit described in the following embodiments of the present application, reference can be made to the aforementioned related description.

[0108] FIG7 is a flowchart of a method for determining a configuration according to an embodiment of the present application. As shown in FIG7 , the method includes the following steps:

[0109] Step 701: The terminal device determines to operate with a first configuration on the band combination corresponding to the first type of time domain unit, and / or to operate with a second configuration on the band combination corresponding to the second type of time domain unit; wherein, an uplink subband is configured on the band combination corresponding to the first type of time domain unit, and an uplink subband is not configured on the band combination corresponding to the second type of time domain unit; the first type of time domain unit is a downlink time domain unit; the second type of time domain unit is a downlink time domain unit; and the band combination includes multiple carriers.

[0110] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0111] In some embodiments, multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network device side. This situation can be called the second mode of multiple carriers. For the second mode, the network device only needs to have one set of uplink RF filters and uplink antenna systems, and the hardware cost of the device is relatively low. A set of uplink RF filters and uplink antenna systems corresponds to multiple carriers, the uplink antenna system is used for the network device to receive multiple carriers, and the uplink RF filter is used for the network device to filter out the uplink sub-band part from the received multiple carriers. Here, the multiple carriers corresponding to a set of uplink RF filters and uplink antenna systems can be called a band combination. In the second mode, the terminal device determines to operate with the first configuration on the band combination corresponding to the first type of time domain unit, and / or to operate with the second configuration on the band combination corresponding to the second type of time domain unit. For more understanding of the "second mode", please refer to the above related description. For the second mode, each carrier in the multiple carriers is interrelated, that is, each carrier in the band combination is interrelated. This association is reflected in that each carrier in the band combination operates using the first configuration or the second configuration. In this way, each carrier in the band combination can correspond to a unified uplink RF filter and a unified uplink antenna system on the network equipment side. Since multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network equipment side, the hardware cost on the network equipment side is low, and it is compatible with the existing single-carrier system, and the upgrade cost of the network equipment is low.

[0112] It should be noted that the multiple carriers correspond to a unified uplink RF filter on the network device side, which means that each of the multiple carriers is filtered using the same uplink RF filter on the network device side.

[0113] When each of the multiple carriers uses the same uplink RF filter on the network device side for filtering, the network device only needs to be configured with one uplink RF filter, effectively saving the device hardware cost.

[0114] It should be noted that when multiple carriers correspond to a unified uplink antenna system on the network device side, this means that each of the multiple carriers is received using the same uplink antenna system on the network device side. The uplink antenna system here includes one or more uplink receive antennas, and the uplink antenna system is used by the network device to receive the multiple carriers.

[0115] Here, the terminal device determines to operate using the first configuration on the band combination corresponding to the first type of time domain unit, specifically referring to: the terminal device determines to operate using the first configuration on each carrier of the band combination corresponding to the first type of time domain unit. The first configurations used on different carriers can be independent or unified.

[0116] Here, the terminal device determines to operate using the second configuration on the band combination corresponding to the second type of time domain unit, specifically referring to: the terminal device determines to operate using the second configuration on each carrier of the band combination corresponding to the second type of time domain unit. The second configurations used on different carriers can be independent or unified.

[0117] In the above solution, each carrier within the band combination operates with the same configuration. As a result, each carrier within the band combination can correspond to a unified uplink RF filter and a unified uplink antenna system on the network equipment side. Because each carrier within the multiple carriers corresponds to a unified uplink RF filter and a unified uplink antenna system on the network equipment side, the hardware cost on the network equipment side is low, and it is compatible with existing carrier systems, reducing the upgrade cost of network equipment.

[0118] In some embodiments, the band combination includes carrier 1, carrier 2, and carrier 3. The first configuration or second configuration used on different carriers can be independent. Carrier 1 uses configuration 11 (i.e., the first configuration) or configuration 21 (i.e., the second configuration), carrier 2 uses configuration 12 (i.e., the first configuration) or configuration 22 (i.e., the second configuration), and carrier 3 uses configuration 13 (i.e., the first configuration) or configuration 23 (i.e., the second configuration). If the band combination is configured with an uplink subband, the terminal device operates using configuration 11 on carrier 1, configuration 12 on carrier 2, and configuration 13 on carrier 3. If the band combination is not configured with an uplink subband, the terminal device operates using configuration 21 on carrier 1, configuration 22 on carrier 2, and configuration 23 on carrier 3.

[0119] In some embodiments, the band combination includes carrier 1, carrier 2, and carrier 3. The first configuration or second configuration used on different carriers can be unified, and carrier 1, carrier 2, and carrier 3 uniformly use configuration 1 (i.e., the first configuration) or configuration 2 (i.e., the second configuration). If the band combination is configured with an uplink subband, the terminal device operates using configuration 1 on carriers 1, carrier 2, and carrier 3; if the band combination is not configured with an uplink subband, the terminal device operates using configuration 2 on carriers 1, carrier 2, and carrier 3.

[0120] The "configuration" described in the embodiments of the present application includes at least one of the following: uplink power configuration, CSI reporting configuration, and spatial relationship configuration. Accordingly, the "operation" described in the embodiments of the present application includes at least one of the following:

[0121] Determine the uplink transmit power according to the uplink power configuration, and use the uplink transmit power to transmit uplink signals;

[0122] Perform CSI measurement according to the CSI reporting configuration; or, perform CSI measurement and CSI reporting.

[0123] An uplink transmission beam is determined according to the spatial relationship configuration, and the uplink transmission beam is used to transmit an uplink signal.

[0124] In some embodiments, if at least one carrier in the band combination corresponding to the first type of time domain unit is configured with an uplink subband, the terminal device determines that an uplink subband is configured on the band combination corresponding to the first type of time domain unit; and / or, if all carriers in the band combination corresponding to the second type of time domain unit are not configured with an uplink subband, the terminal device determines that an uplink subband is not configured on the band combination corresponding to the second type of time domain unit.

[0125] Here, for a downlink time domain unit, if at least one carrier in the band combination corresponding to the downlink time domain unit is configured with an uplink subband, the terminal device determines that the band combination corresponding to the downlink time domain unit is configured with an uplink subband and / or the downlink time domain unit belongs to the above-mentioned first type of time domain unit; if all carriers in the band combination corresponding to the downlink time domain unit are not configured with an uplink subband, the terminal device determines that the band combination corresponding to the downlink time domain unit is not configured with an uplink subband and / or the downlink time domain unit belongs to the above-mentioned second type of time domain unit.

[0126] In some embodiments, a band combination includes carrier 1, carrier 2, and carrier 3. If at least one of carrier 1, carrier 2, and carrier 3 is configured with an uplink subband, the band combination is considered to be configured with an uplink subband; if none of carrier 1, carrier 2, and carrier 3 is configured with an uplink subband, the band combination is considered to be unconfigured with an uplink subband.

[0127] If the number of carriers configured with uplink subbands in a band combination exceeds one, the carriers configured with uplink subbands in the band combination are contiguous. For more information on "band combination," refer to the aforementioned related description. For more information on "contiguous carriers," refer to the aforementioned related description.

[0128] In some implementations, the multiple carrier mode is agreed upon by the protocol. For example, the multiple carrier mode agreed upon by the protocol is the second mode described above. In other implementations, the multiple carrier mode is configured by the network device. For example, the multiple carrier mode configured by the network device is the second mode described above.

[0129] The terminal device determines the mode of multiple carriers; if the mode of multiple carriers is the second mode, the terminal device determines to operate using the first configuration on the band combination corresponding to the first type of time domain unit, and / or determines to operate using the second configuration on the band combination corresponding to the second type of time domain unit.

[0130] In this embodiment of the present application, the first configuration is a configuration corresponding to sub-band full-duplex, or a configuration exclusive to sub-band full-duplex, or a configuration exclusive to the first type of time domain unit (such as an SBFD time domain unit). The second configuration is a configuration corresponding to non-sub-band full-duplex, or a conventional configuration, or a configuration for the second type of time domain unit (such as a non-SBFD time domain unit or a conventional time domain unit). The first configuration is at least partially different from the second configuration.

[0131] In some implementations, the first configuration includes at least one of the following: a first uplink power configuration, a first CSI reporting configuration, and a first spatial relationship configuration.

[0132] The terminal device performs uplink transmission on a band combination configured with an uplink subband according to the first uplink power configuration. In some embodiments, the first uplink power configuration includes at least one parameter of a first target receive power and a first open-loop power adjustment amount. The terminal device may determine or adjust the uplink transmit power according to the first uplink power configuration, and transmit an uplink signal according to the uplink transmit power.

[0133] The terminal device performs CSI reporting (or CSI feedback) on the band combination configured with the uplink subband according to the first CSI reporting configuration. In some embodiments, the first CSI reporting configuration includes at least one parameter of a first antenna port, a first signal transmit power, and a first number of antenna panels. The terminal device performs CSI measurement and corresponding CSI reporting according to the first CSI reporting configuration.

[0134] Here, CSI measurement means that the terminal device measures the signal quality of the downlink reference signal sent by the network device, and determines the CSI of the downlink channel based on the signal quality of the downlink reference signal.

[0135] The terminal device performs uplink transmission on a band combination configured with an uplink subband according to the first spatial relationship configuration. Here, the first spatial relationship configuration is used to determine a beam used for uplink transmission, and the terminal device uses the beam for uplink transmission.

[0136] In some implementations, the second configuration includes at least one of the following: a second uplink power configuration, a second CSI reporting configuration, and a second spatial relationship configuration.

[0137] The terminal device performs uplink transmission on a band combination for which no uplink subband is configured, based on the second uplink power configuration. In some embodiments, the second uplink power configuration includes at least one parameter selected from a second target received power and a second open-loop power adjustment amount. The terminal device may determine or adjust the uplink transmit power based on the second uplink power configuration, and transmit an uplink signal based on the uplink transmit power.

[0138] The terminal device performs CSI reporting (or CSI feedback) on a band combination not configured with an uplink subband according to the second CSI reporting configuration. In some embodiments, the second CSI reporting configuration includes at least one parameter selected from the group consisting of a second antenna port, a second signal transmit power, and a second number of antenna panels. The terminal device performs CSI measurement and corresponding CSI reporting according to the second CSI reporting configuration.

[0139] The terminal device performs uplink transmission on a band combination that is not configured with an uplink subband according to the second spatial relationship configuration. Here, the second spatial relationship configuration is used to determine a beam used for uplink transmission, and the terminal device uses the beam for uplink transmission.

[0140] In some embodiments, the network device adopts different antenna configurations for the first type of time domain unit (such as the SBFD time domain unit) and the second type of time domain unit (such as the non-SBFD time domain unit) (refer to the relevant description of Figure 4). To this end, the terminal device adopts different uplink power configurations for the first type of time domain unit and the second type of time domain unit, which can make up for the difference in the network device's configuration of receiving antennas and ensure uplink coverage. For the first type of time domain unit, the network device is configured with a smaller number of receiving antennas (for example, the number of receiving antennas of the first type of time domain unit is half the number of receiving antennas of the second type of time domain unit). Accordingly, the network device needs to configure a larger target receiving power (i.e., a first uplink power configuration) to make up for the problem of a smaller number of receiving antennas, thereby ensuring uplink coverage. For the second type of time domain unit, the network device is configured with a larger number of receiving antennas. Accordingly, the network device can configure a smaller target receiving power (i.e., a second uplink power configuration) to reduce the energy consumption of the terminal device.

[0141] In some embodiments, the network device adopts different antenna configurations for the first type of time domain unit (such as the SBFD time domain unit) and the second type of time domain unit (such as the non-SBFD time domain unit) (refer to the relevant description of Figure 4). To this end, the terminal device adopts different CSI reporting configurations for the first type of time domain unit and the second type of time domain unit, which can make up for the difference in the network device's receiving antenna configuration. For the first type of time domain unit, the network device is configured with fewer receiving antennas (for example, the number of receiving antennas of the first type of time domain unit is half the number of receiving antennas of the second type of time domain unit). Accordingly, the network device needs to be configured with fewer antenna ports and a smaller number of antenna panels (i.e., the first CSI reporting configuration) to adapt to the problem of a smaller number of receiving antennas. For the second type of time domain unit, the network device is configured with a larger number of receiving antennas. Accordingly, the network device can be configured with more antenna ports and a larger number of antenna panels (i.e., the second CSI reporting configuration) to adapt to the problem of a larger number of receiving antennas.

[0142] In some embodiments, if one of two adjacent time domain units belongs to the above-mentioned first type of time domain unit and the other time domain unit belongs to the above-mentioned second type of time domain unit, the terminal device determines that there is a switching interval between the two adjacent time domain units, and the switching interval is used for uplink and downlink transmission switching; if the two adjacent time domain units both belong to the above-mentioned first type of time domain unit or the above-mentioned second type of time domain unit, the terminal device determines that there is no switching interval between the two adjacent time domain units.

[0143] In some embodiments, if the band combination corresponding to one of two adjacent downlink time domain units is configured with an uplink subband and the band combination corresponding to the other downlink time domain unit is not configured with an uplink subband, the terminal device determines that there is a switching interval between the two adjacent downlink time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the terminal device has sufficient time to switch uplink and downlink transmissions. If the band combinations corresponding to two adjacent downlink time domain units are both configured with an uplink subband or are not configured with an uplink subband, the terminal device determines that there is no switching interval between the two adjacent downlink time domain units.

[0144] FIG8 is a second flow chart of a method for determining a configuration provided in an embodiment of the present application. As shown in FIG8 , the method includes the following steps:

[0145] Step 801: The terminal device determines to operate with a first configuration on the band combination corresponding to the first type of time domain unit, and / or to operate with a second configuration on the band combination corresponding to the second type of time domain unit; wherein, an uplink subband is configured on the band combination corresponding to the first type of time domain unit, and an uplink subband is not configured on the band combination corresponding to the second type of time domain unit; the first type of time domain unit is a flexible time domain unit; the second type of time domain unit is a flexible time domain unit; and the band combination includes multiple carriers.

[0146] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0147] In some implementations, the flexible time domain unit may be configured to be used for downlink transmission, and the flexible time domain unit used for downlink transmission may be understood as a downlink time domain unit.

[0148] Here, step 801 can refer to the description related to step 701 in the aforementioned Figure 7, and step 801 can be implemented by replacing the "downlink time domain unit" in the description related to step 701 with "flexible time domain unit".

[0149] FIG9 is a flow chart of a method for determining a configuration according to an embodiment of the present application. As shown in FIG9 , the method includes the following steps:

[0150] Step 901: The terminal device determines to operate using a first configuration on a carrier corresponding to a first type of time domain unit, and / or to operate using a second configuration on the carrier corresponding to a second type of time domain unit; wherein, an uplink subband is configured on the carrier corresponding to the first type of time domain unit, and an uplink subband is not configured on the carrier corresponding to the second type of time domain unit; the first type of time domain unit is a downlink time domain unit; the second type of time domain unit is a downlink time domain unit; and the carrier is any one of multiple carriers.

[0151] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0152] In some embodiments, each of the multiple carriers corresponds to an independent uplink RF filter and an independent uplink antenna system on the network device side. This situation can be referred to as the first mode of multi-carrier communication. For the first mode, the network device requires multiple sets of uplink RF filters and uplink antenna systems, each corresponding to a carrier. The uplink antenna system is used by the network device to receive the carrier, and the uplink RF filter is used by the network device to filter out the uplink subband portion from the received carrier. Each of the multiple carriers can be independently configured with an uplink subband. Uplink subbands may be configured for some, all, or none of the multiple carriers. In the first mode, for any one of the multiple carriers, the terminal device determines to operate using the first configuration on the carrier corresponding to the first type of time domain unit and / or to operate using the second configuration on the carrier corresponding to the second type of time domain unit. For more information on the "first mode," please refer to the relevant description above. For the first mode, each of the multiple carriers can be independently configured with an uplink subband. The configuration used by each carrier is more flexible and can improve system performance.

[0153] It should be noted that each carrier in the multiple carriers corresponds to an independent uplink RF filter, which means that different carriers in the multiple carriers are filtered using different uplink RF filters.

[0154] When different carriers among multiple carriers are filtered using different uplink RF filters, the network equipment needs to be configured with multiple uplink RF filters. Different carriers are filtered by different uplink RF filters respectively. Each carrier can be independently configured with an uplink sub-band, making the configuration of the uplink sub-band more flexible.

[0155] It should be noted that each of the multiple carriers corresponds to an independent uplink antenna system, which means that different carriers in the multiple carriers are received using different uplink antenna systems. The uplink antenna system here includes one or more uplink receiving antennas, and the uplink antenna system is used for network equipment to receive carriers.

[0156] In the above scheme, each carrier within the multiple carriers can adopt a different configuration, which depends on whether an uplink subband is configured on the carrier. If an uplink subband is configured on the carrier, the carrier adopts the first configuration; if an uplink subband is not configured on the carrier, the carrier adopts the second configuration. In this way, each carrier within the multiple carriers can be flexibly configured.

[0157] The "configuration" described in the embodiments of the present application includes at least one of the following: uplink power configuration, CSI reporting configuration, and spatial relationship configuration. Accordingly, the "operation" described in the embodiments of the present application includes at least one of the following:

[0158] Determine the uplink transmit power according to the uplink power configuration, and use the uplink transmit power to transmit uplink signals;

[0159] Perform CSI measurement according to the CSI reporting configuration; or, perform CSI measurement and CSI reporting.

[0160] An uplink transmission beam is determined according to the spatial relationship configuration, and the uplink transmission beam is used to transmit an uplink signal.

[0161] Here, for a downlink time domain unit, if the carrier corresponding to the downlink time domain unit is configured with an uplink subband, the terminal device determines that the downlink time domain unit belongs to the above-mentioned first type of time domain unit; if the carrier corresponding to the downlink time domain unit is not configured with an uplink subband, the terminal device determines that the downlink time domain unit belongs to the above-mentioned second type of time domain unit.

[0162] In some implementations, the multiple carrier mode is agreed upon by the protocol. For example, the multiple carrier mode agreed upon by the protocol is the first mode described above. In other implementations, the multiple carrier mode is configured by the network device. For example, the multiple carrier mode configured by the network device is the first mode described above.

[0163] The terminal device determines the mode of multiple carriers; if the mode of multiple carriers is the first mode, then for any one of the multiple carriers, the terminal device determines to operate using the first configuration on the carrier corresponding to the first type of time domain unit, and / or determines to operate using the second configuration on the carrier corresponding to the second type of time domain unit.

[0164] In this embodiment of the present application, the first configuration is a configuration corresponding to sub-band full-duplex, or a configuration exclusive to sub-band full-duplex, or a configuration exclusive to the first type of time domain unit (such as an SBFD time domain unit). The second configuration is a configuration corresponding to non-sub-band full-duplex, or a conventional configuration, or a configuration for the second type of time domain unit (such as a non-SBFD time domain unit or a conventional time domain unit). The first configuration is at least partially different from the second configuration.

[0165] In some implementations, the first configuration includes at least one of the following: a first uplink power configuration, a first CSI reporting configuration, and a first spatial relationship configuration.

[0166] The terminal device performs uplink transmission on a carrier configured with an uplink subband according to the first uplink power configuration. In some embodiments, the first uplink power configuration includes at least one parameter selected from a first target receive power and a first open-loop power adjustment amount. The terminal device may determine or adjust the uplink transmit power according to the first uplink power configuration, and transmit an uplink signal according to the uplink transmit power.

[0167] The terminal device performs CSI reporting (or CSI feedback) on a carrier configured with an uplink subband according to the first CSI reporting configuration. In some embodiments, the first CSI reporting configuration includes at least one parameter selected from the group consisting of a first antenna port, a first signal transmit power, and a first number of antenna panels. The terminal device performs CSI measurement and corresponding CSI reporting according to the first CSI reporting configuration.

[0168] Here, CSI measurement means that the terminal device measures the signal quality of the downlink reference signal sent by the network device, and determines the CSI of the downlink channel based on the signal quality of the downlink reference signal.

[0169] The terminal device performs uplink transmission on a carrier configured with an uplink subband according to the first spatial relationship configuration. Here, the first spatial relationship configuration is used to determine a beam used for uplink transmission, and the terminal device uses the beam for uplink transmission.

[0170] In some implementations, the second configuration includes at least one of the following: a second uplink power configuration, a second CSI reporting configuration, and a second spatial relationship configuration.

[0171] The terminal device performs uplink transmission on a carrier not configured with an uplink subband according to the second uplink power configuration. In some embodiments, the second uplink power configuration includes at least one parameter of a second target received power and a second open-loop power adjustment amount. The terminal device may determine or adjust the uplink transmit power according to the second uplink power configuration, and transmit an uplink signal according to the uplink transmit power.

[0172] The terminal device performs CSI reporting (or CSI feedback) on a carrier not configured with an uplink subband according to the second CSI reporting configuration. In some embodiments, the second CSI reporting configuration includes at least one parameter selected from the group consisting of a second antenna port, a second signal transmit power, and a second number of antenna panels. The terminal device performs CSI measurement and corresponding CSI reporting according to the second CSI reporting configuration.

[0173] The terminal device performs uplink transmission on a carrier that is not configured with an uplink subband according to the second spatial relationship configuration. Here, the second spatial relationship configuration is used to determine a beam used for uplink transmission, and the terminal device uses the beam for uplink transmission.

[0174] In some embodiments, the network device adopts different antenna configurations for the first type of time domain unit (such as the SBFD time domain unit) and the second type of time domain unit (such as the non-SBFD time domain unit) (refer to the relevant description of Figure 4). To this end, the terminal device adopts different uplink power configurations for the first type of time domain unit and the second type of time domain unit, which can make up for the difference in the network device's configuration of receiving antennas and ensure uplink coverage. For the first type of time domain unit, the network device is configured with a smaller number of receiving antennas (for example, the number of receiving antennas of the first type of time domain unit is half the number of receiving antennas of the second type of time domain unit). Accordingly, the network device needs to configure a larger target receiving power (i.e., a first uplink power configuration) to make up for the problem of a smaller number of receiving antennas, thereby ensuring uplink coverage. For the second type of time domain unit, the network device is configured with a larger number of receiving antennas. Accordingly, the network device can configure a smaller target receiving power (i.e., a second uplink power configuration) to reduce the energy consumption of the terminal device.

[0175] In some embodiments, the network device adopts different antenna configurations for the first type of time domain unit (such as the SBFD time domain unit) and the second type of time domain unit (such as the non-SBFD time domain unit) (refer to the relevant description of Figure 4). To this end, the terminal device adopts different CSI reporting configurations for the first type of time domain unit and the second type of time domain unit, which can make up for the difference in the network device's receiving antenna configuration. For the first type of time domain unit, the network device is configured with fewer receiving antennas (for example, the number of receiving antennas of the first type of time domain unit is half the number of receiving antennas of the second type of time domain unit). Accordingly, the network device needs to be configured with fewer antenna ports and a smaller number of antenna panels (i.e., the first CSI reporting configuration) to adapt to the problem of a smaller number of receiving antennas. For the second type of time domain unit, the network device is configured with a larger number of receiving antennas. Accordingly, the network device can be configured with more antenna ports and a larger number of antenna panels (i.e., the second CSI reporting configuration) to adapt to the problem of a larger number of receiving antennas.

[0176] In some embodiments, if one of two adjacent time domain units belongs to the above-mentioned first type of time domain unit and the other time domain unit belongs to the above-mentioned second type of time domain unit, the terminal device determines that there is a switching interval between the two adjacent time domain units, and the switching interval is used for uplink and downlink transmission switching; if the two adjacent time domain units both belong to the above-mentioned first type of time domain unit or the above-mentioned second type of time domain unit, the terminal device determines that there is no switching interval between the two adjacent time domain units.

[0177] In some embodiments, if the carrier corresponding to one of two adjacent downlink time domain units is configured with an uplink subband and the carrier corresponding to the other downlink time domain unit is not configured with an uplink subband, the terminal device determines that there is a switching interval between the two adjacent downlink time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the terminal device has sufficient time to switch uplink and downlink transmissions. If the carriers corresponding to two adjacent downlink time domain units are both configured with an uplink subband or are not configured with an uplink subband, the terminal device determines that there is no switching interval between the two adjacent downlink time domain units.

[0178] FIG10 is a fourth flow chart of a method for determining a configuration according to an embodiment of the present application. As shown in FIG10 , the method includes the following steps:

[0179] Step 1001: The terminal device determines to operate using a first configuration on a carrier corresponding to a first type of time domain unit, and / or to operate using a second configuration on the carrier corresponding to a second type of time domain unit; wherein, an uplink subband is configured on the carrier corresponding to the first type of time domain unit, and an uplink subband is not configured on the carrier corresponding to the second type of time domain unit; the first type of time domain unit is a flexible time domain unit; the second type of time domain unit is a flexible time domain unit; the carrier is any one of multiple carriers.

[0180] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0181] In some implementations, the flexible time domain unit may be configured to be used for downlink transmission, and the flexible time domain unit used for downlink transmission may be understood as a downlink time domain unit.

[0182] Here, step 1001 can refer to the description related to step 901 in the aforementioned Figure 9, and step 1001 can be implemented by replacing the "downlink time domain unit" in the description related to step 901 with "flexible time domain unit".

[0183] It should be noted that in the embodiments of Figures 7 to 10 above, the first type of time domain unit and the second type of time domain unit are both downlink time domain units or both flexible time domain units. The technical solution of the embodiment of the present application may also have the following other embodiments.

[0187] 4) The first type of time domain unit is a flexible time domain unit, and the second type of time domain unit is a downlink time domain unit. Replace "the first type of time domain unit is a downlink time domain unit" in the description related to Figure 9 above with "the first type of time domain unit is a flexible time domain unit" to implement some embodiments.

[0188] FIG11 is a flowchart diagram 5 of a method for determining a configuration provided in an embodiment of the present application. As shown in FIG11 , the method includes the following steps:

[0189] Step 1101: The network device sends a first configuration and / or a second configuration to the terminal device, wherein the first configuration is used for the terminal device to operate on the band combination corresponding to the first type of time domain unit, and the second configuration is used for the terminal device to operate on the band combination corresponding to the second type of time domain unit; wherein, the band combination corresponding to the first type of time domain unit is configured with an uplink subband, and the band combination corresponding to the second type of time domain unit is not configured with an uplink subband; the band combination includes multiple carriers.

[0190] In some embodiments, the first type of time domain unit is a downlink time domain unit, and the second type of time domain unit is a downlink time domain unit. In other embodiments, the first type of time domain unit is a flexible time domain unit, and the second type of time domain unit is a flexible time domain unit. In other embodiments, the first type of time domain unit is a downlink time domain unit, and the second type of time domain unit is a flexible time domain unit. In other embodiments, the first type of time domain unit is a flexible time domain unit, and the second type of time domain unit is a downlink time domain unit.

[0191] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0192] In some embodiments, multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network device side. This situation can be called the second mode of multiple carriers. For the second mode, the network device only needs to have one set of uplink RF filters and uplink antenna systems, and the hardware cost of the device is relatively low. A set of uplink RF filters and uplink antenna systems corresponds to multiple carriers, the uplink antenna system is used for the network device to receive multiple carriers, and the uplink RF filter is used for the network device to filter out the uplink sub-band part from the received multiple carriers. Here, the multiple carriers corresponding to a set of uplink RF filters and uplink antenna systems can be called a band combination. In the second mode, the terminal device determines to operate with the first configuration on the band combination corresponding to the first type of time domain unit, and / or to operate with the second configuration on the band combination corresponding to the second type of time domain unit. For more understanding of the "second mode", please refer to the above related description. For the second mode, each carrier in the multiple carriers is interrelated, that is, each carrier in the band combination is interrelated. This association is reflected in that each carrier in the band combination operates using the first configuration or the second configuration. In this way, each carrier in the band combination can correspond to a unified uplink RF filter and a unified uplink antenna system on the network equipment side. Since multiple carriers correspond to a unified uplink RF filter and a unified uplink antenna system on the network equipment side, the hardware cost on the network equipment side is low, and it is compatible with the existing single-carrier system, and the upgrade cost of the network equipment is low.

[0193] It should be noted that the multiple carriers correspond to a unified uplink RF filter on the network device side, which means that each of the multiple carriers is filtered using the same uplink RF filter on the network device side.

[0194] When each of the multiple carriers uses the same uplink RF filter on the network device side for filtering, the network device only needs to be configured with one uplink RF filter, effectively saving the device hardware cost.

[0195] It should be noted that when multiple carriers correspond to a unified uplink antenna system on the network device side, this means that each of the multiple carriers is received using the same uplink antenna system on the network device side. The uplink antenna system here includes one or more uplink receive antennas, and the uplink antenna system is used by the network device to receive the multiple carriers.

[0196] In some embodiments, the network device sends the first configuration and / or the second configuration to the terminal device via Radio Resource Control (RRC) signaling.

[0197] In this embodiment of the present application, the first configuration is a configuration corresponding to sub-band full-duplex, or a configuration exclusive to sub-band full-duplex, or a configuration exclusive to the first type of time domain unit (such as an SBFD time domain unit). The second configuration is a configuration corresponding to non-sub-band full-duplex, or a conventional configuration, or a configuration for the second type of time domain unit (such as a non-SBFD time domain unit or a conventional time domain unit). The first configuration is at least partially different from the second configuration.

[0198] Here, for more understanding of the “first configuration” and / or the “second configuration”, please refer to the related descriptions of Figures 7 to 10 mentioned above.

[0199] In some embodiments, if one of two adjacent time domain units belongs to the above-mentioned first type of time domain unit and the other time domain unit belongs to the above-mentioned second type of time domain unit, the network device determines that there is a switching interval between the two adjacent time domain units, and the switching interval is used for uplink and downlink transmission switching; if the two adjacent time domain units both belong to the above-mentioned first type of time domain unit or the above-mentioned second type of time domain unit, the network device determines that there is no switching interval between the two adjacent time domain units.

[0200] In some embodiments, if the band combination corresponding to one of two adjacent downlink time domain units is configured with an uplink subband and the band combination corresponding to the other downlink time domain unit is not configured with an uplink subband, the network device determines that there is a switching interval between the two adjacent downlink time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the network device has sufficient time to switch uplink and downlink transmissions. If the band combinations corresponding to the two adjacent downlink time domain units are both configured with an uplink subband or are neither configured with an uplink subband, the network device determines that there is no switching interval between the two adjacent downlink time domain units.

[0201] In some embodiments, if the band combination corresponding to one flexible time domain unit in two adjacent downlink time domain units is configured with an uplink subband and the band combination corresponding to the other flexible time domain unit is not configured with an uplink subband, the network device determines that there is a switching interval between the two adjacent flexible time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the network device has sufficient time to switch uplink and downlink transmissions. If the band combinations corresponding to the two adjacent flexible time domain units are both configured with an uplink subband or are not configured with an uplink subband, the network device determines that there is no switching interval between the two adjacent flexible time domain units.

[0202] FIG12 is a sixth flow chart of a method for determining a configuration according to an embodiment of the present application. As shown in FIG12 , the method includes the following steps:

[0203] Step 1201: The network device sends a first configuration and / or a second configuration to the terminal device, where the first configuration is used for the terminal device to operate on the carrier corresponding to the first type of time domain unit, and the second configuration is used for the terminal device to operate on the carrier corresponding to the second type of time domain unit; wherein, an uplink subband is configured on the carrier corresponding to the first type of time domain unit, and an uplink subband is not configured on the carrier corresponding to the second type of time domain unit; the carrier is any one of multiple carriers.

[0204] In some embodiments, the first type of time domain unit is a downlink time domain unit, and the second type of time domain unit is a downlink time domain unit. In other embodiments, the first type of time domain unit is a flexible time domain unit, and the second type of time domain unit is a flexible time domain unit. In other embodiments, the first type of time domain unit is a downlink time domain unit, and the second type of time domain unit is a flexible time domain unit. In other embodiments, the first type of time domain unit is a flexible time domain unit, and the second type of time domain unit is a downlink time domain unit.

[0205] The technical solution of the embodiment of the present application is applied to a multi-carrier system. In the multi-carrier system, multiple carriers are used for communication between a terminal device and a network device.

[0206] In some embodiments, each of the multiple carriers corresponds to an independent uplink RF filter and an independent uplink antenna system on the network device side. This situation can be referred to as the first mode of multi-carrier communication. For the first mode, the network device requires multiple sets of uplink RF filters and uplink antenna systems, each corresponding to a carrier. The uplink antenna system is used by the network device to receive the carrier, and the uplink RF filter is used by the network device to filter out the uplink subband portion from the received carrier. Each of the multiple carriers can be independently configured with an uplink subband. Uplink subbands may be configured for some, all, or none of the multiple carriers. In the first mode, for any one of the multiple carriers, the terminal device determines to operate using the first configuration on the carrier corresponding to the first type of time domain unit and / or to operate using the second configuration on the carrier corresponding to the second type of time domain unit. For more information on the "first mode," please refer to the relevant description above. For the first mode, each of the multiple carriers can be independently configured with an uplink subband. The configuration used by each carrier is more flexible and can improve system performance.

[0207] It should be noted that each carrier in the multiple carriers corresponds to an independent uplink RF filter, which means that different carriers in the multiple carriers are filtered using different uplink RF filters.

[0208] When different carriers among multiple carriers are filtered using different uplink RF filters, the network equipment needs to be configured with multiple uplink RF filters. Different carriers are filtered by different uplink RF filters respectively. Each carrier can be independently configured with an uplink sub-band, making the configuration of the uplink sub-band more flexible.

[0209] It should be noted that each of the multiple carriers corresponds to an independent uplink antenna system, which means that different carriers in the multiple carriers are received using different uplink antenna systems. The uplink antenna system here includes one or more uplink receiving antennas, and the uplink antenna system is used for network equipment to receive carriers.

[0210] In the above scheme, each carrier within the multiple carriers can adopt a different configuration, which depends on whether an uplink subband is configured on the carrier. If an uplink subband is configured on the carrier, the carrier adopts the first configuration; if an uplink subband is not configured on the carrier, the carrier adopts the second configuration. In this way, each carrier within the multiple carriers can be flexibly configured.

[0211] In some embodiments, the network device sends the first configuration and / or the second configuration to the terminal device via RRC signaling.

[0212] In this embodiment of the present application, the first configuration is a configuration corresponding to sub-band full-duplex, or a configuration exclusive to sub-band full-duplex, or a configuration exclusive to the first type of time domain unit (such as an SBFD time domain unit). The second configuration is a configuration corresponding to non-sub-band full-duplex, or a conventional configuration, or a configuration for the second type of time domain unit (such as a non-SBFD time domain unit or a conventional time domain unit). The first configuration is at least partially different from the second configuration.

[0213] Here, for more understanding of the “first configuration” and / or the “second configuration”, please refer to the related descriptions of Figures 7 to 10 mentioned above.

[0214] In some embodiments, if one of two adjacent time domain units belongs to the above-mentioned first type of time domain unit and the other time domain unit belongs to the above-mentioned second type of time domain unit, the network device determines that there is a switching interval between the two adjacent time domain units, and the switching interval is used for uplink and downlink transmission switching; if the two adjacent time domain units both belong to the above-mentioned first type of time domain unit or the above-mentioned second type of time domain unit, the network device determines that there is no switching interval between the two adjacent time domain units.

[0215] In some embodiments, if the carrier corresponding to one of two adjacent downlink time domain units is configured with an uplink subband and the carrier corresponding to the other downlink time domain unit is not configured with an uplink subband, the network device determines that there is a switching interval between the two adjacent downlink time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the network device has sufficient time to switch uplink and downlink transmissions. If the carriers corresponding to the two adjacent downlink time domain units are both configured with an uplink subband or are not configured with an uplink subband, the network device determines that there is no switching interval between the two adjacent downlink time domain units.

[0216] In some embodiments, if the carrier corresponding to one flexible time domain unit in two adjacent downlink time domain units is configured with an uplink subband and the carrier corresponding to the other flexible time domain unit is not configured with an uplink subband, the network device determines that there is a switching interval between the two adjacent flexible time domain units, and the switching interval is used to switch uplink and downlink transmissions. The switching interval can ensure that the network device has sufficient time to switch uplink and downlink transmissions. If the carriers corresponding to the two adjacent flexible time domain units are both configured with an uplink subband or are not configured with an uplink subband, the network device determines that there is no switching interval between the two adjacent flexible time domain units.

[0217] The following is an example of the technical solution of the embodiment of the present application, which is illustrated by combining specific application examples. In the following application examples, the time domain unit is a symbol, but it is not limited to this. The time domain unit can also be a subframe, a time slot, a sub-time slot, etc.

[0218] Application Example 1

[0219] The network device supports multi-carrier duplex mode. In multi-carrier duplex mode, the network device configures an independent uplink RF filter and an independent uplink antenna system for each of the multiple carriers. In addition, the network device can configure a unified downlink RF filter and a unified downlink antenna system for the multiple carriers, or it can configure an independent downlink RF filter and an independent downlink antenna system for each of the multiple carriers.

[0220] For a carrier, if the carrier is configured with an uplink subband on a symbol, the symbol is an SBFD symbol. If the carrier is not configured with an uplink subband on a symbol, the symbol is a non-SBFD symbol. The terminal device operates on the SBFD symbol according to the first configuration and / or operates on the non-SBFD symbol according to the second configuration. In other words, the terminal device operates on the carrier configured with an uplink subband according to the first configuration and / or operates on the carrier not configured with an uplink subband according to the second configuration. Here, for more understanding of the "first configuration" and the "second configuration", please refer to the aforementioned related description.

[0221] Taking carrier n (carrier n is one of multiple downlink carriers) as an example, if carrier n is configured with an uplink subband on symbol x, the terminal device operates using the first configuration on symbol x of carrier n; if carrier n is not configured with an uplink subband on symbol x, the terminal device operates using the second configuration on symbol x of carrier n.

[0222] In some embodiments, as shown in FIG13 , the multiple carriers include carrier 1, carrier 2, and carrier 3, wherein an uplink subband is configured on symbol x of carrier 2 and carrier 3, and no uplink subband is configured on symbol y of carrier 1, carrier 2, and carrier 3. Carrier 2 and carrier 3 each use independent uplink RF filters for uplink RF filtering. The terminal device determines the duplex mode of the multiple carriers, which can be agreed upon by the protocol or configured by the network device. This duplex mode is the first mode. For more information about the "first mode," please refer to the aforementioned related description.

[0223] 1) The terminal device determines the uplink power configuration of carrier n on symbol x based on whether the uplink subband is configured for carrier n on symbol x. If the uplink subband is configured for carrier n on symbol x, the uplink power configuration adopted by carrier n on symbol x (i.e., SBFD symbol) is determined to be the first uplink power configuration; if the uplink subband is not configured for carrier n on symbol x, the uplink power configuration adopted by carrier n on symbol x (i.e., non-SBFD symbol) is determined to be the second uplink power configuration. The first uplink power configuration and the second uplink power configuration are configured by the network device. For more information on the "first uplink power configuration" and "second uplink power configuration", please refer to the above-mentioned related description. For the two cases of "configuring the uplink subband" and "not configuring the uplink subband", the network device adopts different receiving antenna configurations for SBFD symbols and non-SBFD symbols. Please refer to the relevant description in Figure 4. The terminal device adopts different uplink power configurations for SBFD symbols and non-SBFD symbols, which can make up for the difference in the network device's receiving antenna configuration and ensure uplink coverage. For example: For carriers configured with uplink subbands (corresponding to SBFD symbols), the network device is configured with fewer receiving antennas (for example, the number of receiving antennas for carriers configured with uplink subbands is half the number of receiving antennas for carriers not configured with uplink subbands). Accordingly, the network device needs to configure a larger target receive power (i.e., the first uplink power configuration) to compensate for the smaller number of receive antennas, thereby ensuring uplink coverage. Conversely, for carriers not configured with uplink subbands (corresponding to non-SBFD symbols), the network device is configured with a larger number of receiving antennas. Accordingly, the network device can configure a smaller target receive power (i.e., the second uplink power configuration) to reduce the energy consumption of the terminal device.

[0224] Taking Figure 13 as an example, since carriers 2 and 3 are configured with an uplink subband on symbol x1, carriers 2 and 3 use the first uplink power configuration on symbol x1, e.g., target received power P0 = 0. Since carrier 1 is not configured with an uplink subband on symbol x1 and carriers 1, 2, and 3 are not configured with an uplink subband on symbol x2, carrier 1 uses the second uplink power configuration on symbol x1 and carriers 1, 2, and 3 use the second uplink power configuration on symbol x2, e.g., target received power P0 = -3.

[0225] 2) The terminal device determines the CSI reporting configuration of carrier n on symbol x based on whether carrier n is configured with an uplink subband on symbol x. If carrier n is configured with an uplink subband on symbol x, the CSI reporting configuration adopted by carrier n on symbol x (i.e., SBFD symbol) is determined to be the first CSI reporting configuration; if carrier n is not configured with an uplink subband on symbol x, the CSI reporting configuration adopted by carrier n on symbol x (i.e., non-SBFD symbol) is determined to be the second CSI reporting configuration. The first CSI reporting configuration and the second CSI reporting configuration are configured by the network device. For more information on the "first CSI reporting configuration" and the "second CSI reporting configuration", please refer to the relevant description above. For the two cases of "configuring an uplink subband" and "not configuring an uplink subband", the network device adopts different receiving antenna configurations for SBFD symbols and non-SBFD symbols. Please refer to the relevant description of Figure 4. The terminal device adopts different CSI reporting configurations for SBFD symbols and non-SBFD symbols, which can make up for the difference in the network device's receiving antenna configuration. For example: for a carrier configured with an uplink subband (corresponding to an SBFD symbol), the network device is configured with fewer receive antennas (for example, the number of receive antennas for a carrier configured with an uplink subband is half the number of receive antennas for a carrier not configured with an uplink subband). Accordingly, the network device needs to be configured with fewer antenna ports and a smaller number of antenna panels (i.e., the first CSI reporting configuration). Conversely, for a carrier not configured with an uplink subband (corresponding to a non-SBFD symbol), the network device is configured with more receive antennas. Accordingly, the network device can be configured with more antenna ports and a larger number of antenna panels (i.e., the second CSI reporting configuration).

[0226] Taking Figure 13 as an example, since carriers 2 and 3 are configured with an uplink subband on symbol x1, carriers 2 and 3 use the first CSI reporting configuration on symbol x1, such as a configuration of 2 antenna ports and 1 antenna panel. Since carrier 1 is not configured with an uplink subband on symbol x1 and carriers 1, 2, and 3 are not configured with an uplink subband on symbol x2, carrier 1 on symbol x1 and carriers 1, 2, and 3 use the second CSI reporting configuration on symbol x2, such as a configuration of 4 antenna ports and 2 antenna panels (each antenna panel contains a codebook for 2 antenna ports).

[0227] It should be noted that the CSI reporting configuration described in the embodiments of the present application may also be replaced by a CSI measurement configuration.

[0228] 3) The terminal device and / or the network device determines whether there is a switching interval between symbol x and symbol x-1 based on whether the carrier n is configured with an uplink subband on symbol x and symbol x-1. If the carrier n is not configured with an uplink subband on symbol x-1 and is configured with an uplink subband on symbol x, or the carrier n is configured with an uplink subband on symbol x-1 and is not configured with an uplink subband on symbol x, then there is a switching interval between symbol x-1 and symbol x of carrier n. If the carrier n is configured with an uplink subband on both symbol x and symbol x-1 or is not configured with an uplink subband on either, then there is no switching interval between symbol x-1 and symbol x of carrier n. Here, the switching interval is to reserve time for the uplink and downlink transmission conversion to ensure that the terminal device and / or the network device has enough time to convert the uplink and downlink transmission.

[0229] Taking Figure 13 as an example, for carriers 2 and 3, symbols x1 and x2 are adjacent, but only symbol x1 is configured with an uplink subband, while symbol x2 is not. Therefore, a switching interval is required between symbols x1 and x2 on carriers 2 and 3, and the interval between signals scheduled by the network device on these two symbols must be greater than or equal to this switching interval. For carrier 1, symbols x1 and x2 are adjacent, but neither symbol x1 or x2 is configured with an uplink subband. Therefore, a switching interval is not required between symbols x1 and x2 on carrier 1, meaning that the signals scheduled by the network device on these two symbols can be continuous.

[0230] Application Example 2

[0231] Network devices support multi-carrier duplex mode. In multi-carrier duplex mode, the network device configures a unified uplink RF filter and a unified uplink antenna system for multiple carriers. Multiple carriers are referred to as a band combination. Furthermore, the network device can configure a unified downlink RF filter and a unified downlink antenna system for each band combination.

[0232] For a band combination, if the band combination is configured with an uplink subband on a symbol, the symbol is an SBFD symbol. If the band combination is not configured with an uplink subband on a symbol, the symbol is a non-SBFD symbol. The terminal device operates on the SBFD symbol according to the first configuration and / or operates on the non-SBFD symbol according to the second configuration. In other words, the terminal device operates on the band combination configured with an uplink subband according to the first configuration and / or operates on the band combination not configured with an uplink subband according to the second configuration. Here, for more understanding of the "first configuration" and the "second configuration", please refer to the aforementioned related description.

[0233] Taking band combination n as an example, if band combination n is configured with an uplink subband, regardless of whether the uplink subband is configured on one carrier or multiple carriers of band combination n, the terminal device adopts the first configuration to operate on each carrier of band combination n; if band combination n is not configured with an uplink subband, that is, all carriers in band combination n are not configured with an uplink subband, the terminal device adopts the second configuration to operate on each carrier of carrier n.

[0234] In some embodiments, as shown in FIG14 , the terminal device determines that the carriers included in the band combination n include carrier 1, carrier 2, and carrier 3. Band combination n can be pre-set or can also be reported by the terminal device to the network device. Among them, carrier 2 corresponding to symbol x1 is configured with an uplink subband, and all carriers corresponding to symbol x2 are not configured with an uplink subband, that is, band combination n is configured with an uplink subband on symbol x1, band combination n is not configured with an uplink subband on symbol x2, and carrier 2 uses a unified uplink RF filter for uplink RF filtering. The terminal device determines the duplex mode of the multiple carriers, which can be agreed upon by the protocol or configured by the network device. This duplex mode is the second mode, and more understanding of the "second mode" can refer to the aforementioned related description.

[0235] 1) The terminal device determines the uplink power configuration for band combination n on symbol x based on whether an uplink subband is configured for band combination n on symbol x. If an uplink subband is configured for band combination n on symbol x, the uplink power configuration used by band combination n on symbol x (i.e., an SBFD symbol) is determined to be the first uplink power configuration. If an uplink subband is not configured for band combination n on symbol x, the uplink power configuration used by band combination n on symbol x (i.e., a non-SBFD symbol) is determined to be the second uplink power configuration. The first and second uplink power configurations are configured by the network device. For more information on the "first uplink power configuration" and "second uplink power configuration," please refer to the aforementioned related description. For the two cases of "uplink subband configured" and "uplink subband not configured," the network device uses different receive antenna configurations for SBFD symbols and non-SBFD symbols. Refer to the related description in FIG. 4 . The terminal device uses different uplink power configurations for SBFD symbols and non-SBFD symbols to compensate for the differences in the network device's receive antenna configurations and ensure uplink coverage. For example, for band combinations with uplink subbands configured (corresponding to SBFD symbols), the network device is configured with fewer receiving antennas (for example, the number of receiving antennas for band combinations with uplink subbands configured is half the number of receiving antennas for band combinations without uplink subbands configured). Accordingly, the network device needs to configure a larger target receive power (i.e., the first uplink power configuration) to compensate for the smaller number of receive antennas, thereby ensuring uplink coverage. Conversely, for band combinations without uplink subbands configured (corresponding to non-SBFD symbols), the network device is configured with a larger number of receiving antennas. Accordingly, the network device can configure a smaller target receive power (i.e., the second uplink power configuration) to reduce the energy consumption of the terminal device.

[0236] Taking Figure 14 as an example, since band combination n is configured with an uplink subband on symbol x1, carriers 1, 2, and 3 in band combination n adopt the first uplink power configuration on symbol x1. Since band combination n is not configured with an uplink subband on symbol x2, carriers 1, 2, and 3 in band combination n adopt the second uplink power configuration on symbol x2. Here, the first uplink power configuration and the second uplink power configuration of carriers 1, 2, and 3 can be configured uniformly or independently. Taking the independent configuration as an example, for symbol x1, the target received powers of carriers 1, 2, and 3 are configured as P11, P12, and P13, respectively; for symbol x2, the target received powers of carriers 1, 2, and 3 are configured as P21, P22, and P23, respectively. Typically, for band combinations with uplink subbands, network devices are configured with fewer receive antennas (for example, the number of receive antennas for band combinations with uplink subbands is half of the number for band combinations without uplink subbands). Accordingly, network devices need to configure a larger target receive power to compensate for the smaller number of receive antennas and thus ensure uplink coverage. Conversely, for band combinations without uplink subbands, network devices are configured with a larger number of receive antennas. Accordingly, network devices can configure a smaller target receive power to reduce energy consumption of terminal devices. Therefore, P11>P21, P12>P22, and P12>P22.

[0237] 2) The terminal device determines the CSI reporting configuration of band combination n on symbol x based on whether the band combination n is configured with an uplink subband on symbol x. If the band combination n is configured with an uplink subband on symbol x, the CSI reporting configuration adopted by the band combination n on symbol x (i.e., SBFD symbol) is determined to be the first CSI reporting configuration; if the band combination n is not configured with an uplink subband on symbol x, the CSI reporting configuration adopted by the band combination n on symbol x (i.e., non-SBFD symbol) is determined to be the second CSI reporting configuration. The first CSI reporting configuration and the second CSI reporting configuration are configured by the network device. For more understanding of the "first CSI reporting configuration" and the "second CSI reporting configuration", please refer to the aforementioned related description. For the two cases of "uplink subband configured" and "uplink subband not configured", the network device adopts different receiving antenna configurations for SBFD symbols and non-SBFD symbols. The relevant description of Figure 4 can be referred to. The terminal device adopts different CSI reporting configurations for SBFD symbols and non-SBFD symbols, which can make up for the difference in the network device's receiving antenna configuration. For example: for the band combination with uplink subband configured (corresponding to SBFD symbols), the network device configures fewer receiving antennas (for example, the number of receiving antennas for the band combination with uplink subband configured is half of the number of receiving antennas for the band combination without uplink subband configured). Accordingly, the network device needs to configure fewer antenna ports and a smaller number of antenna panels (i.e., the first CSI reporting configuration). Conversely, for the band combination with no uplink subband configured (corresponding to non-SBFD symbols), the network device configures more receiving antennas. Accordingly, the network device can configure more antenna ports and a larger number of antenna panels (i.e., the second CSI reporting configuration).

[0238] Taking Figure 14 as an example, since band combination n is configured with an uplink subband on symbol x1, all carriers in band combination n use the first CSI reporting configuration on symbol x1, such as a 2-antenna port configuration. Since band combination n is not configured with an uplink subband on symbol x2, all carriers in band combination n use the second CSI reporting configuration on symbol x2, such as a 4-antenna port configuration.

[0239] It should be noted that the CSI reporting configuration described in the embodiments of the present application may also be replaced by a CSI measurement configuration.

[0240] 3) The terminal device and / or the network device determines whether there is a switching interval between symbol x and symbol x-1 based on whether the band combination n is configured with an uplink subband on symbol x and symbol x-1. If the band combination n is not configured with an uplink subband on symbol x-1 and is configured with an uplink subband on symbol x, or if the band combination n is configured with an uplink subband on symbol x-1 and is not configured with an uplink subband on symbol x, then there is a switching interval between symbol x-1 and symbol x of the band combination n. If the band combination n is configured with an uplink subband on both symbol x and symbol x-1 or is not configured with an uplink subband on either, then there is no switching interval between symbol x-1 and symbol x of the band combination n. Here, the switching interval is to reserve time for the uplink and downlink transmission conversion to ensure that the terminal device and / or the network device has enough time to convert the uplink and downlink transmission.

[0241] Taking Figure 14 as an example, for band combination n, symbol x1 and symbol x2 are adjacent but only symbol x1 is configured with an uplink subband, and symbol x2 is not configured with an uplink subband. In this case, a switching interval is required between symbol x1 and symbol x2 of band combination n, and the interval between the signals scheduled by the network device on these two symbols needs to be greater than or equal to the switching interval.
