Description
Time-frequency resource configuration method, device, terminal and network side equipment
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application No. 202311187487.4 filed on September 14, 2023, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present application belongs to the field of communication technology, and specifically relates to a time-frequency resource configuration method, apparatus, terminal, and network-side equipment. Background Art
[0004] With the development of communication technology, communication systems will support more flexible duplex modes. As the flexibility of duplex modes increases, the existing time division duplex (TDD) uplink and downlink configurations, base station-side subband full duplex (SBFD) operations, and bandwidth part (BWP) configuration methods will become more complex. However, existing resource configuration methods cannot effectively support different duplex modes. Support for new duplex modes is usually achieved by superimposing resource configurations, resulting in redundant configuration of signaling and configuration parameters. In addition, in related technologies, after configuring an uplink subband on a flexible symbol, it is unclear whether the remaining frequency domain resources on the flexible symbol are downlink subbands or flexible subbands, resulting in ambiguous resource attributes.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.
[0062] For better understanding, the following explains relevant concepts that may be involved in the embodiments of this application.
[0063] Currently, mobile communication systems need to adapt to increasingly diverse scenarios and service requirements. For example, key 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine type communication (mMTC). These scenarios place high reliability, low latency, large bandwidth, and wide coverage demands on the system. For different carriers, the base station configures the corresponding uplink and downlink configuration (TDD-UL-DL-Configuration). Each time slot / symbol is designated as uplink, downlink, or a flexible time slot / symbol. On each carrier, the terminal operates only within its activated UL bandwidth part (BWP) or activated DL BWP. In Rel-18, base station-side subband full-duplex (SBFD) operation was introduced. In an SBFD slot, the base station can perform uplink and downlink transmissions simultaneously on different frequency domain resources. The uplink resource is the UL subband configured by the base station, which is located in the activated DL BWP.
[0064] TDD uplink and downlink configuration (TDD-UL-DL-Configuration):
[0065] In LTE, uplink and downlink configurations are based on time slots, or subframes. LTE TDD includes seven configurations.
[0066] In NR, uplink and downlink configuration is based on symbol granularity, which is more flexible. The specific configuration process is as follows:
[0067] (1) First, configure the semi-static uplink and downlink configuration of the cell:
[0068] The upper layer provides the parameter common TDD uplink and downlink configuration (TDD-UL-DL-Configuration Common), which includes the reference subcarrier spacing u (reference SCS configuration) and pattern 1. Pattern 1 also includes:
[0069] Slot configuration period (P ms)
[0070] Downlink timeslot number Dslots (number of slots with only downlink symbols)
[0071] Number of downlink symbols Dsym
[0072] Uslots (number of slots with only uplink symbols)
[0073] Usym (number of uplink symbols)
[0074] In the configuration period, the first Dslots time slots are downlink time slots, followed by Dsym downlink symbols, then Usym uplink symbols, and finally Uslots uplink time slots. The remaining symbols are flexible symbols X. Each TDD UL-DL configuration contains at least one DL symbol / time slot, and / or UL symbol / time slot, and / or flexible symbol / time slot.
[0075] (2) Then configure the terminal-specific uplink and downlink configuration:
[0076] If, based on the configuration in (1), a higher-layer parameter dedicated TDD uplink and downlink configuration (TDD-UL-DL-ConfigDedicated) is further provided, this parameter can configure the flexible symbols of TDD-UL-DL-ConfigurationCommon. In other words, the uplink and downlink symbols configured in (1) cannot be changed, but the flexible symbols can be overwritten by TDD-UL-DL-ConfigurationDedicated.
[0077] This parameter provides a series of slot configurations. For each slot configuration, it provides a slot index and symbol configuration. For the slot specified by slot index, the following are the values:
[0078] If symbols=allDownlink, all symbols in the slot are downlink.
[0079] If symbols=allUplink, all symbols in the slot are uplink.
[0080] If symbols=explicit, the parameter nrofDownlinkSymbols provides a number of downlink first.
[0081] That is, if explicit is used, the parameter nrofDownlinkSymbols specifies the number of downlink symbols, and nrofUplinkSymbols specifies the number of uplink symbols, with downlink symbols first and uplink symbols last. If nrofDownlinkSymbols is not provided, there are no downlink symbols, and if nrofUplinkSymbols is not provided, there are no uplink symbols. If any symbols remain after configuration, they are still flexible symbols X. The reference SCS configuration in (2) is the same as in (1).
[0082] (3) Dynamic Downlink Control Information (DCI) uplink and downlink configuration:
[0083] Dynamic DCI implementation of uplink and downlink configuration is achieved through DCI format 2-0, or directly through uplink and downlink data scheduling using DCI formats 0-0, 0-1, 1-0, and 1-1. DCI format 2-0 is specifically used as a slot format indicator (SFI). The SFI primarily implements periodic frame structure configuration based on the slot formats supported by a single slot. That is, starting from the receipt of DCI format 2-0, the physical downlink control channel (PDCCH) monitoring period (monitoring period) of slots is continuously configured according to the instructions of the SFI in this DCI. The maximum number of formats supported by a single slot is 256, and 56 formats have been standardized.
[0084] BWP:
[0085] In NR, the network configures one or more BWPs for user equipment (UE) and / or performs data transmission. BWP is a continuous resource in the frequency domain. The UE achieves dynamic bandwidth changes by activating different BWPs. As shown in Figure 1b, at the first moment, the UE's traffic volume is large, and the UE activates a large bandwidth (BWP1); at the second moment, the UE's traffic volume is small, and the UE activates a small bandwidth (BWP2) to meet basic communication needs; at the third moment, the system finds that there is large-scale frequency selective fading in the bandwidth where BWP1 is located, or that resources in the frequency range where BWP2 is located are relatively scarce, so it instructs the UE to activate a new bandwidth (BWP3).
[0086] Each BWP may correspond to different configuration parameters, including subcarrier spacing, BWP location and bandwidth, and cyclic prefix (CP).
[0087] SBFD:
[0088] As shown in Figure 1c, after the base station configures the UE with the UL BWP, DL BWP, and TDD uplink and downlink configurations, it can configure the time and frequency domain resources for SBFD operation. The frequency domain resources include at least the UL subband, which is used for uplink transmission. For example, SBFD operation is configured in the third, fourth, and fifth semi-statically configured DL slots, and the UL subband is effective within these slots. The base station can simultaneously receive uplink transmissions on the UL subband and perform downlink transmissions on the DL subband within the SBFD symbols / timeslots, thereby implementing SBFD on the base station side. The terminal can only receive on the DL subband or transmit on the UL subband within the SBFD symbols / timeslots. Furthermore, if the terminal can simultaneously receive on the DL subband or transmit on the UL subband within the SBFD symbols / timeslots, SBFD on the terminal side can be implemented.
[0089] The time-frequency resource configuration method, apparatus, and related equipment provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.
[0090] Please refer to Figure 2, which is a flow chart of a method for configuring time-frequency resources provided by an embodiment of the present application, the method being executed by a terminal. As shown in Figure 2, the method includes the following steps:
[0091] Step 201: A terminal receives first configuration information sent by a network-side device. The first configuration information is used to indicate at least one set of time-frequency resources. The set of time-frequency resources includes at least one of the following:
[0092] At least one time domain transmission unit, the time domain transmission unit corresponding to at least one transmission type, and the time domain transmission unit of one transmission type corresponding to at least one frequency domain resource;
[0093] At least one frequency domain resource, each of the frequency domain resources corresponding to a time domain indication information, the time domain indication information being in units of time domain transmission units, and indicating whether the frequency domain resource in each time domain transmission unit is activated;
[0094] The at least one frequency domain resource includes at least one of a bandwidth part BWP or subband, an uplink BWP, a downlink BWP, an uplink subband and a downlink subband; and the at least one transmission type includes at least one of an uplink transmission type, a downlink transmission type, a mixed transmission type and a flexible transmission type.
[0095] It should be noted that BWP and subband only represent a part of the frequency domain resources, and the frequency domain resources in the embodiments of the present application are not limited to BWP or subband in the prior art.
[0096] In an embodiment of the present application, a network-side device sends first configuration information, and the first configuration information is used to indicate at least one group of time-frequency resources. For example, the first configuration information may be an indication of configuring at least one group of time-frequency resources for the terminal, or the at least one group of time-frequency resources indicated by the first configuration information may also be used for the network-side device, or the at least one group of time-frequency resources indicated by the first configuration information is the time-frequency resources of the system, which can be used for the network-side device and the terminal. It can be understood that the time-frequency resources include time domain resources and / or frequency domain resources. Exemplarily, a group of time-frequency resources may include at least one time domain transmission unit, and the time domain transmission unit corresponds to at least one transmission type. The transmission type may be related to the transmission direction, for example, the transmission type may be an uplink transmission type, a downlink transmission type, a mixed transmission type, or a flexible transmission type.
[0097] A time domain transmission unit of one transmission type corresponds to at least one frequency domain resource, and time domain transmission units of different transmission types correspond to different frequency domain resources. For example, the frequency domain resources corresponding to a time domain transmission unit of an uplink transmission type include an uplink BWP or an uplink subband, and the frequency domain resources corresponding to a time domain transmission unit of a downlink transmission type include a downlink BWP or a downlink subband.
[0098] Alternatively, a set of time-frequency resources may include at least one frequency domain resource, each of which corresponds to a time domain indication information. The time domain indication information indicates, in units of time domain transmission units, whether the frequency domain resource within each time domain transmission unit is activated. The frequency domain resources may include an uplink BWP, a downlink BWP, an uplink subband, a downlink subband, a guard band, and the like. Downlink transmission can occur within a downlink BWP or a downlink subband, uplink transmission can occur within an uplink BWP or an uplink subband, and there is no corresponding transmission within a guard band, i.e., no corresponding transmission direction. In this embodiment of the present application, each frequency domain resource corresponds to a time domain indication information. The time domain indication information indicates, in units of time domain transmission units, whether the frequency domain resource within each time domain transmission unit is activated. For example, if the frequency domain resource includes an uplink BWP, and the time domain indication information corresponding to the uplink BWP indicates that the uplink BWP is activated, then uplink transmission can occur within the uplink BWP. If the time domain indication information corresponding to the uplink BWP indicates that the uplink BWP is inactive, then no transmission occurs within the uplink BWP. Optionally, the time domain indication information may simultaneously indicate whether the frequency domain resources in each time domain transmission unit in a plurality of time domain transmission units are activated.
[0099] In an embodiment of the present application, a terminal receives first configuration information sent by a network-side device, and the first configuration information is used for at least one group of time-frequency resources, wherein the group of time-frequency resources includes at least one time domain transmission unit and / or at least one frequency domain resource, thereby realizing the time-frequency resource configuration of the network-side device or the terminal. Among them, the time domain transmission unit corresponds to at least one of the uplink transmission type, the downlink transmission type, the mixed transmission type and the flexible transmission type, thereby realizing the configuration of multiple transmission types of the time domain transmission unit, and a time domain transmission unit of one transmission type corresponds to at least one frequency domain resource, such as an uplink BWP or a downlink BWP. The time domain transmission unit can correspond to the uplink BWP or the downlink BWP, thereby realizing the time domain transmission unit can transmit on the uplink BWP or transmit on the downlink BWP, thereby realizing the terminal or the network side can simultaneously send on the uplink BWP and receive on the downlink BWP in the time domain transmission unit, thereby realizing the terminal side or the network side can flexibly support different duplex modes. In addition, a group of time-frequency resources may also include at least one frequency domain resource, and each of the frequency domain resources corresponds to a time domain indication information, and the time domain indication information is used to indicate whether the frequency domain resource is activated, so that the terminal or the network side can determine whether transmission can be performed in the frequency domain resource based on the time domain indication information, and can also determine whether multiple duplex modes on the terminal side and the network side can be realized. In the embodiment of the present application, the first configuration information sent by the network side device can more flexibly configure the time-frequency resources, so that the terminal side and the network side can flexibly support a variety of different duplex modes, and realize the unified configuration of time-frequency resources. Compared with the prior art method that requires further superimposing the time-frequency resource configuration related to the SBFD operation on the basis of the UL / DL BWP configuration and the TDD uplink and downlink configuration, the embodiment of the present application can realize the flexible configuration of multiple different duplex modes through the first configuration information, avoiding the problem of redundant configuration of signaling and configuration parameters, and by limiting the time domain transmission unit of each transmission type to correspond to at least one frequency domain resource, the resource attributes of the time-frequency resources are defined, avoiding the problem of ambiguity in resource attributes.
[0100] Optionally, different frequency domain resources correspond to different subcarrier intervals.
[0101] In addition, the first configuration information also includes the starting position and the ending position of the frequency domain resources, or the starting position and the bandwidth of the frequency domain resources.
[0102] Optionally, when the transmission type corresponding to the time domain transmission unit is an uplink transmission type, the time domain transmission unit of the uplink transmission type is used for uplink transmission; or,
[0103] In a case where the transmission type corresponding to the time domain transmission unit is a downlink transmission type, the time domain transmission unit of the downlink transmission type is used for downlink transmission; or
[0104] In a case where the transmission type corresponding to the time domain transmission unit is a hybrid transmission type, the time domain transmission unit of the hybrid transmission type is used for uplink transmission and downlink transmission; or,
[0105] In a case where the transmission type corresponding to the time domain transmission unit is a flexible transmission type, there is no restriction on the transmission direction of the time domain transmission unit of the flexible transmission type; or
[0106] In a case where the transmission type corresponding to the time domain transmission unit includes the uplink transmission type and the downlink transmission type, the time domain transmission unit is used to perform uplink transmission, or downlink transmission, or uplink transmission and downlink transmission.
[0107] Optionally, different time domain transmission units may correspond to different transmission types, for example, time domain transmission unit A is an uplink transmission type, time domain transmission unit B is a mixed transmission type, etc. It should be noted that the time domain transmission unit in the embodiment of the present application may be one or more time slots, symbols, subframes, frames, milliseconds, seconds, etc.
[0108] In the embodiment of the present application, the method may further include:
[0109] The terminal performs uplink transmission or downlink transmission according to the first configuration information.
[0110] For example, the first configuration information indicates a set of time-frequency resources, the set of time-frequency resources includes a time domain transmission unit (e.g., a time slot), the transmission type corresponding to the time domain transmission unit is an uplink transmission type, and the frequency domain resources corresponding to the time domain transmission unit include a BWP. Then, according to the first configuration information, the terminal performs uplink transmission on the BWP corresponding to the time domain transmission unit indicated by the first configuration information. Of course, the first configuration information may also represent other possible situations, which are not listed in detail in this embodiment.
[0111] Optionally, the transmission type of the time domain transmission unit can be semi-statically configured through high-layer signaling or dynamically configured through physical layer signaling. The frequency domain resources corresponding to the time domain transmission unit can also be semi-statically configured through high-layer signaling or dynamically configured through physical layer signaling.
[0112] Optionally, in a case where the transmission type corresponding to one of the time domain transmission units includes the uplink transmission type and the downlink transmission type, based on the scheduling of the network side device, the time domain transmission unit is used to perform uplink transmission, or downlink transmission, or uplink transmission and downlink transmission. When performing uplink transmission and downlink transmission, if the frequency domain resources corresponding to the uplink transmission type and the downlink transmission type have non-overlapping parts, the network side device or terminal can perform uplink transmission or downlink transmission on the non-overlapping resources; if the frequency domain resources corresponding to the uplink transmission type and the downlink transmission type have overlapping parts, the network side device or terminal can perform uplink transmission or downlink transmission on the overlapping resources.
[0113] Optionally, the frequency domain resources corresponding to the time domain transmission unit of the hybrid transmission type include frequency domain resources for uplink transmission (e.g., BWP or subband) and frequency domain resources for downlink transmission (e.g., BWP or subband). In other words, the frequency domain resources corresponding to the time domain transmission unit of the hybrid transmission type include at least two parts of frequency domain resources, one part of which is used for downlink transmission and the other part of which is used for uplink transmission.
[0114] It should be noted that the frequency domain resources used by the terminal side for uplink transmission and downlink transmission may overlap.
[0115] Optionally, the frequency domain resources corresponding to the time domain transmission unit of the mixed transmission type further include a guard band.
[0116] In the embodiment of the present application, the method may further include:
[0117] The terminal receives a first signaling sent by a network side device;
[0118] The terminal adjusts the transmission type of the time domain transmission unit according to the first signaling.
[0119] In other words, the terminal can adjust the transmission type of the time domain transmission unit based on the signaling of the network-side device, for example, adjusting the uplink transmission type to a hybrid transmission type. This enables the terminal to flexibly adjust the transmission type of the time domain transmission unit, thereby making the transmission of time-frequency resources on the terminal and the network more flexible. The first signaling can be high-layer signaling or physical layer signaling, which is not specifically limited in this application.
[0120] Optionally, the terminal adjusts the transmission type of the time domain transmission unit according to the first signaling, including at least one of the following:
[0121] 1) When the transmission type corresponding to the time domain transmission unit is the flexible transmission type, the terminal adjusts the transmission type of the time domain transmission unit to any one of the uplink transmission type, the downlink transmission type, and the hybrid transmission type according to the first signaling. Prior to the adjustment, the time domain transmission unit of the flexible transmission type has no corresponding frequency domain resources.
[0122] 2) When the transmission type corresponding to the time domain transmission unit is the uplink transmission type or the downlink transmission type, the terminal adjusts the transmission type of the time domain transmission unit to the mixed transmission type according to the first signaling.
[0123] 3) When the transmission type corresponding to the time domain transmission unit is the mixed transmission type, the terminal adjusts the transmission type of the time domain transmission unit to the uplink transmission type or the downlink transmission type according to the first signaling.
[0124] In the embodiment of the present application, flexible adjustment of the transmission type of the time domain transmission unit can be achieved, effectively improving the transmission flexibility between the terminal and the network side device.
[0125] Optionally, when the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type is adjusted to the time domain transmission unit of the hybrid transmission type, the at least one frequency domain resource corresponding to the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type includes at least one of the following:
[0126] BWP, the BWP has no uplink or downlink transmission attributes, and is not limited to uplink BWP or downlink BWP;
[0127] Upward BWP;
[0128] Downward BWP.
[0129] Optionally, when the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type is adjusted to the time domain transmission unit of the hybrid transmission type, the at least one frequency domain resource corresponding to the time domain transmission unit of the hybrid transmission type includes at least one of the following:
[0130] Upstream sub-band;
[0131] Downward sub-band;
[0132] Protective belt.
[0133] In this way, when the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type is adjusted to the time domain transmission unit of the mixed transmission type, the frequency domain range of the adjusted time domain transmission unit will not exceed the frequency domain range before adjustment, so that the relevant configuration parameters of the terminal or base station filter, etc. do not need to be adjusted, thereby ensuring smooth transmission of the terminal.
[0134] Optionally, the transmission type of the time domain transmission unit is divided into at least one subtype, and one of the subtypes corresponds to the at least one frequency domain resource. For example, the transmission type of the time domain transmission unit may be subtype one or subtype two, etc. For example, the transmission type of the time domain transmission unit includes an uplink transmission type, a downlink transmission type, a mixed transmission type, and a flexible transmission type. Exemplarily, the downlink transmission type can be further divided into downlink transmission subtype one, downlink transmission subtype two, etc. Of course, other transmission types can also be divided into at least one subtype, which are not specifically listed here. Among them, one subtype corresponds to at least one frequency domain resource, and the frequency domain resources corresponding to different subtypes may be different.
[0135] In an embodiment of the present application, when a group of time-frequency resources configured by a network-side device includes at least one frequency domain resource, each of the frequency domain resources corresponds to a time domain indication information, and the time domain indication information is in units of time domain transmission units, and indicates whether the frequency domain resources in each time domain transmission unit are activated. It should be noted that a time domain indication information may indicate whether the frequency domain resources in each time domain transmission unit in a plurality of time domain transmission units are activated, or a time domain indication information is used to separately indicate whether the frequency domain resources in a time domain transmission unit are activated. In this way, it is possible to indicate whether the frequency domain resources in each time domain transmission unit are activated through the time domain indication information, thereby helping the terminal to know the activation status of the frequency domain resources in each time domain transmission unit. Among them, whether the frequency domain resources are activated indicates whether the frequency domain resources are available, and does not necessarily require activation behavior or activation process.
[0136] Optionally, when there are no activated frequency domain resources in a time domain transmission unit, the transmission type corresponding to the time domain transmission unit is the flexible transmission type, or the time domain transmission unit is in a dormant state. Exemplarily, if there are no activated frequency domain resources in a time domain transmission unit, the transmission type corresponding to the time domain transmission unit can be considered to be a flexible transmission type, and the transmission direction within the time domain unit is not limited.
[0137] It should be noted that in this case, the network side device can dynamically adjust or semi-statically configure the transmission of control signaling, data or reference signals within the time domain transmission unit, thereby performing uplink transmission or downlink transmission.
[0138] Alternatively, when only frequency domain resources for a first transmission direction are activated within a time domain transmission unit, the transmission type corresponding to the time domain transmission unit is related to the first transmission direction, where the first transmission direction is either an uplink transmission direction or a downlink transmission direction. For example, if only frequency domain resources for a downlink transmission direction are activated within a time domain transmission unit, the transmission type corresponding to the time domain transmission unit is a downlink transmission type; if only frequency domain resources for an uplink transmission direction are activated within the time domain transmission unit, the transmission type corresponding to the time domain transmission unit is an uplink transmission type.
[0139] Alternatively, in the case where a time domain transmission unit includes activated uplink transmission frequency domain resources and downlink transmission frequency domain resources, if the uplink transmission frequency domain resources and the downlink transmission frequency domain resources do not overlap or partially overlap, then the transmission type corresponding to the time domain transmission unit is the mixed transmission type; if the uplink transmission frequency domain resources and the downlink transmission frequency domain resources completely overlap, then the transmission type corresponding to the time domain transmission unit is the mixed transmission type or the flexible transmission type.
[0140] In this case, the network side device can implement SBFD or partial / full overlapping full duplex on the terminal side or the network side device side through scheduling or configuration in the time domain transmission unit of the flexible transmission type or the time domain transmission unit of the hybrid transmission type.
[0141] Alternatively, when a guard band within a time domain transmission unit is activated, the guard band or frequency domain resources overlapping with the guard band are not transmitted.
[0142] Optionally, the frequency domain resources may be semi-statically configured through higher layer signaling, or dynamically configured through physical layer signaling. The time domain indication information corresponding to the frequency domain resources may also be semi-statically configured through higher layer signaling, or dynamically configured through physical layer signaling.
[0143] Optionally, the time domain indication information corresponding to each frequency domain resource is independently configured. For example, the time domain indication information or time domain transmission unit lengths corresponding to different frequency domain resources may be different, and the configuration periods may also be different.
[0144] In an embodiment of the present application, a terminal receives first configuration information sent by a network device, where the first configuration information indicates at least one set of time-frequency resources. For example, the network device may send the first configuration information multiple times, or send multiple first configuration information at a time, thereby configuring at least two sets of time-frequency resources for the terminal. Alternatively, the first configuration information sent by the network device may indicate multiple sets of time-frequency resources at a time.
[0145] Optionally, when the first configuration information is used to indicate at least two groups of time-frequency resources, the at least two groups of time-frequency resources each correspond to different spatial domain information, and the network side device or terminal can be simultaneously receiving and / or transmitting in different spatial domains. The network side device or terminal can implement SBFD or partial / full overlapping full duplex.
[0146] The spatial information may be transmit-receive point (TRP) information, beam identification information, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, transmission configuration indicator (TCI) state information, quasi co-location (QCL) information or QCL parameters, etc.
[0147] Optionally, when the first configuration information is used to indicate at least two groups of time-frequency resources, at least one group of the at least two groups of time-frequency resources is a cell-specific time-frequency resource or a group-specific time-frequency resource, and at least one group of the at least two groups of time-frequency resources is a terminal-specific time-frequency resource; or,
[0148] At least one of the at least two groups of time-frequency resources is the time-frequency resources of the terminal, and at least one of the at least two groups of time-frequency resources is the time-frequency resources of the network side device.
[0149] Optionally, when at least one of the at least two groups of time-frequency resources is a cell-dedicated or group-dedicated time-frequency resource, and at least one of the at least two groups of time-frequency resources is a terminal-dedicated time-frequency resource, the terminal preferentially uses the terminal-dedicated time-frequency resources, or the terminal determines the available time-frequency resources based on the intersection of the cell-dedicated time-frequency resources or the group-dedicated time-frequency resources and the terminal-dedicated time-frequency resources.
[0150] Optionally, at least one of the at least two groups of time-frequency resources is the time-frequency resources of the terminal, and at least one of the at least two groups of time-frequency resources is the time-frequency resources of the network-side device. The terminal preferentially uses the time-frequency resources of the terminal, or the terminal determines the available time-frequency resources based on the intersection of the time-frequency resources of the terminal and the time-frequency resources of the network-side device. For a better understanding, the time-frequency resource configuration method provided in the embodiment of the present application is explained below through several specific implementation methods.
[0151] Implementation method one:
[0152] Referring to Figure 3a , the base station (network-side device) configures each slot type for the UE using a 10-time slot (an example of a time domain transmission unit) cycle, with the following configurations: downlink transmission type (hereinafter abbreviated as DL), mixed transmission type (hereinafter abbreviated as mixed type) 1 (M1 in Figure 3a ), flexible transmission type (hereinafter abbreviated as flexible, such as F in Figure 3a ), mixed type 2 (M2 in Figure 3a ), uplink transmission type (hereinafter abbreviated as UL) 1, DL, mixed type 3 (such as M3 in Figure 3a ), flexible, mixed type 2, UL 2. The sequence number represents the subtype; for example, mixed type 1, mixed type 2, and mixed type 3 are represented as mixed transmission type subtype 1, mixed transmission type subtype 2, and mixed transmission type subtype 3. Each subtype corresponds to a different frequency domain mode. For simplicity, they can be directly referred to as mixed transmission type 1, mixed transmission type 2, and mixed transmission type 3. The other subtypes are expressed in the same way and are not further described. Among them, except for the time slot corresponding to the flexible transmission type (hereinafter abbreviated as flexible slot), other types of slots correspond to at least one frequency domain resource. For example, the frequency domain resources corresponding to the DL slot only include one DL BWP or BWP. The time slot corresponding to the uplink transmission type (hereinafter abbreviated as UL slot) has two subtypes, corresponding to different frequency domain resources, as shown in slot 5 and slot 10, each containing a UL BWP or BWP, but the bandwidth corresponding to the UL BWP or BWP is different, or the subcarrier spacing is different, or the frequency domain position is different. The slot corresponding to the hybrid transmission type has three subtypes, and the corresponding frequency domain resources are shown in slots 2, 4, and 7, including at least one uplink transmission resource, at least one downlink transmission resource, and at least one guard band. Optionally, the guard band may not be included in the frequency domain pattern corresponding to the hybrid transmission type slot. Optionally, the uplink transmission resource may be a UL BWP or UL subband, etc., and the downlink transmission resource may be a DL BWP or DL subband, etc.
[0153] If a flexible slot is rewritten as a UL1 slot, the corresponding frequency domain resources can be the same as those of slot 5. If it is rewritten as mixed type 3, the corresponding frequency domain resources can be the same as those of slot 7, and so on. Similarly, if a UL slot or DL slot is rewritten as a mixed slot, the corresponding frequency domain resources are also changed to those of a mixed slot.
[0154] Implementation method 2:
[0155] The frequency domain resources corresponding to a mixed slot may not include at least one of the UL subband or the DL subband. This configuration is only applicable when rewriting from a DL slot or UL slot to a mixed slot. As shown in Figure 3b, the base station configures the slot types for the UE as DL, DL, flexible (F in Figure 3b), and DL, UL, respectively, with a five-slot period. In the second period, the transmission types of slots 7, 8, and 9 are adjusted (rewritten), that is, the DL slot, flexible slot, and DL slot are adjusted to mixed slots. For example, the frequency domain resources corresponding to mixed type 1 include the UL subband and guard band (as shown in the upper block diagram of mixed type 1 in Figure 3b), but do not include the DL subband; the frequency domain resources corresponding to mixed type 2 include the DL subband and UL subband, but do not include the guard band (as shown in the upper block diagram of mixed type 2 in Figure 3b); and the frequency domain resources corresponding to mixed type 3 include the UL subband and guard band (as shown in the upper block diagram of mixed type 3 in Figure 3b). In the example of Figure 3b, DL slot 7 is rewritten to mixed type 1. If the frequency domain resources corresponding to the DL slot are BWP1 or DL BWP1, the corresponding downlink transmission resources in the mixed type 1 timeslot are the portion of BWP1 or DL BWP1 that does not overlap with the UL subband or guard band. The same logic applies when DL slot 9 is rewritten as mixed type 3. For flexible slot 8, if it is rewritten as a mixed slot, the frequency domain resources of the mixed slot must include at least uplink and downlink transmission resources, as shown in mixed type 2 in Figure 3b.
[0156] Implementation method three:
[0157] The base station configures frequency domain resources for the terminal, including at least one of the following: DL BWP, UL BWP, and guard band. The frequency domain resource distribution is shown in Figure 3c. In configuration 1 (configuration 1 in Figure 3c), the UL BWP and DL BWP do not overlap, and the guard band overlaps with the UL BWP and DL BWP. In configuration 2 (configuration 2 in Figure 3c), the UL BWP and DL BWP partially overlap, and there is no guard band. In configuration 3 (configuration 3 in Figure 3c), the UL BWP and DL BWP fully overlap, and there is no guard band.
[0158] For each configured frequency domain resource, the base station configures time domain indication information. In Figure 3c, 1 indicates that the frequency domain resource is activated, and 0 indicates that it is inactive. The time domain indication information corresponding to each configured frequency domain resource is shown in the bitmap in the figure. The final configured time and frequency resources are shown in the lower portion of Figure 3c. For configurations 1, 2, and 3, only one frequency domain resource is activated in the first, second, and fifth slots. The transmission type of the slot is determined by the transmission direction of the activated frequency domain resource: downlink, downlink, and uplink. The third slot has no DL or UL BWP activated; its slot type is flexible or dormant. In configuration 1, if the guard band in the third slot is activated, resources overlapping with the guard band cannot be used when the slot type is subsequently overwritten. For configurations 1 and 2, the fourth slot contains non-overlapping frequency domain resources (e.g., the UL BWP and DL BWP do not overlap in configuration 1, and the UL BWP and DL BWP partially overlap in configuration 2). This slot can be considered a mixed transmission type slot. The base station or UE can simultaneously transmit or receive on different frequency domain resources. Configuration 1 has fixed uplink and downlink transmission resource bandwidths, while configuration 2 allows for dynamic changes in uplink and downlink transmission resource bandwidths by scheduling them on overlapping frequency domain resources. For configuration 3, the UL BWP and DL BWP of slot 4 completely overlap. This slot can be considered a flexible slot (a time slot with flexible transmission type) or a hybrid slot (a time slot with hybrid transmission type). The base station can implement transmission modes such as DL-only, UL-only, and SBFD through scheduling or configuration.
[0159] Implementation method four:
[0160] As shown in Figure 3d, the base station configures two sets of time-frequency resources for the terminal. Each set of time-frequency resources can correspond to a spatial domain information, such as a TRP / TCI state. Different TRP / TCI states can be associated with different antenna panels. Assume that the total frequency domain bandwidth and starting position of the two sets of time-frequency resources are the same. In slot 1, the terminal receives information sent by TRP1 and TRP2. In slot 2, the terminal can choose to receive data from TRP1 or send data to TRP2 (half duplex on the terminal side); alternatively, the terminal can simultaneously receive data from TRP1 on the entire frequency domain resource and send data to TRP2 (full overlapping full duplex on the terminal side); or receive data from TRP1 and send data to TRP2 on different frequency domain resources (SBFD on the terminal side). Optionally, the terminal receives data from TRP1 in the upper half of the frequency domain resource and sends data to TRP2 of the base station in the lower half of the frequency domain resource. In slot 7, the terminal can send data to TRP1 on the uplink frequency domain resources and receive data from TRP2 on the downlink frequency domain resources, which is SBFD on the terminal side.
[0161] Furthermore, the base station can configure time-frequency resource 1 (configuration 1) for terminal 1 as shown in Figure 3d, and time-frequency resource 2 (configuration 2) for terminal 2 as shown in the previous figure. The two sets of resources correspond to different spatial domain information, such as TRP / TCI state. The base station can send data to terminal 1 in slot 2 and receive data from terminal 2, using full overlapping full duplex on the base station side; or receive data from terminal 1 on the uplink frequency domain resources in slot 7 and send data to terminal 2 on the downlink frequency domain resources, using SBFD on the base station side.
[0162] It should be noted that the frequency domain position and bandwidth of the resources in all the above implementations are only examples, and can actually be any position and any bandwidth, such as shown in FIG3e.
[0163] Please refer to Figure 4, which is a flowchart of another method for configuring time-frequency resources provided by an embodiment of the present application, and the method is executed by a network-side device. As shown in Figure 4, the method includes the following steps:
[0164] Step 401: A network-side device sends first configuration information to a terminal. The first configuration information is used to indicate at least one set of time-frequency resources. The set of time-frequency resources includes at least one of the following:
[0165] At least one time domain transmission unit, the time domain transmission unit corresponding to at least one transmission type, and the time domain transmission unit of one transmission type corresponding to at least one frequency domain resource;

[0170] Optionally, when the transmission type corresponding to the time domain transmission unit is an uplink transmission type, the time domain transmission unit of the uplink transmission type is used for uplink transmission; or,
[0171] In a case where the transmission type corresponding to the time domain transmission unit is a downlink transmission type, the time domain transmission unit of the downlink transmission type is used for downlink transmission; or

[0179] In a case where the transmission type corresponding to the time domain transmission unit is the mixed transmission type, the transmission type of the time domain transmission unit may be adjusted to the uplink transmission type or the downlink transmission type.
[0180] Optionally, when the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type is adjusted to the time domain transmission unit of the hybrid transmission type, the at least one frequency domain resource corresponding to the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type includes at least one of the following:

[0182] Upward BWP;
[0183] Downward BWP.
[0184] Optionally, when the time domain transmission unit of the uplink transmission type or the time domain transmission unit of the downlink transmission type is adjusted to the time domain transmission unit of the hybrid transmission type, the at least one frequency domain resource corresponding to the time domain transmission unit of the hybrid transmission type includes at least one of the following:
[0185] Upstream sub-band;
[0186] Downward sub-band;
[0187] Protective belt.
[0188] Optionally, the transmission type of the time domain transmission unit is divided into at least one subtype, and one subtype corresponds to the at least one frequency domain resource.
[0189] Optionally,
[0190] In a case where there is no activated frequency domain resource in a time domain transmission unit, the transmission type corresponding to the time domain transmission unit is the flexible transmission type, or the time domain transmission unit is in a dormant state; or,
[0191] In a case where only frequency domain resources of a first transmission direction are activated in a time domain transmission unit, the transmission type corresponding to the time domain transmission unit is related to the first transmission direction, and the first transmission direction is an uplink transmission direction or a downlink transmission direction; or
[0192] In a case where a time domain transmission unit includes activated uplink transmission frequency domain resources and downlink transmission frequency domain resources, if the uplink transmission frequency domain resources and the downlink transmission frequency domain resources do not overlap or partially overlap, the transmission type corresponding to the time domain transmission unit is the mixed transmission type; if the uplink transmission frequency domain resources and the downlink transmission frequency domain resources completely overlap, the transmission type corresponding to the time domain transmission unit is the mixed transmission type or the flexible transmission type; or,
[0193] When the guard band in a time domain transmission unit is activated, the guard band or the frequency domain resources overlapping with the guard band are not transmitted.
[0194] Optionally, the time domain indication information corresponding to each frequency domain resource is configured independently.

[0198] It should be noted that the method provided in the embodiment of the present application corresponds to the above-mentioned time-frequency resource configuration method executed by the terminal side. The relevant concepts, specific processes and effective effects involved in this embodiment can be referred to the description in the above-mentioned terminal side method embodiment.
