Description

Signal transmission and reception method, device and communication system Technical Field

[0001] The present application relates to the field of communication technology. Background Art

[0002] In traditional time division duplexing (TDD), time domain resources are divided into downlink and uplink. At any given moment, only downlink or uplink transmissions can occur. Therefore, allocating limited or less uplink-intensive time periods results in reduced coverage and capacity, and increased latency. To address this issue, methods can be proposed that enable network devices to support the simultaneous presence / occurrence / performance of downlink and uplink transmissions. In other words, these devices can be enabled to transmit and receive signals simultaneously.

[0003] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0004] Summary of the Invention

[0005] As a Study Item (SI) in Rel-18, the application scenarios, simulation methods, and potential standardization impact of Subband Non-Overlapping Full Duplex (SBFD) were initially studied.

With SBFD, network devices can operate in full-duplex mode (simultaneous transmit and receive), thereby improving uplink transmission capacity and coverage and reducing uplink latency.

[0006] For a terminal device, downlink signals can be received in a downlink bandwidth (DL BWP) and uplink signals can be sent in an uplink bandwidth (UL BWP). However, there is currently no method for configuring a BWP and receiving or sending signals in the BWP while supporting SBFD operation.

[0084] The following describes the first sub-band, the second sub-band, and the third sub-band.

[0085] In some embodiments, the first subband and the second subband are used, for example, to support SBFD operations (of a network device). From the perspective of the network device, the network device can receive (uplink) signals on the first subband during a time period while simultaneously transmitting (downlink) signals on the second subband during a time period. This enables the possibility of simultaneously transmitting and receiving signals (whether to receive and / or transmit depends on other configurations and / or scheduling). From the perspective of the terminal device, an (uplink) signal can be transmitted on the first subband during the time period or a (downlink) signal can be received on the second subband during the time period (whether to transmit / receive depends on other configurations and / or scheduling).

[0086] In some embodiments, the first subband and / or the second subband (their configuration) are for the same cell or within a cell, or in other words, the SBFD operation is for the same cell or within a cell. From the perspective of a network device, within the same cell, a (uplink) signal can be received on the first subband while a (downlink) signal is transmitted on the second subband during a time period. From the perspective of a terminal device, within the cell, a (uplink) signal can be transmitted on the first subband and / or a (downlink) signal can be received on the second subband during that time period.

[0087] In some embodiments, the third subband is, for example, a guard interval GB between the first subband and the second subband. The third subband and / or the first subband and / or the second subband may include one or more continuous frequency domain resource units or multiple discontinuous frequency domain resource units, or the third subband and the first subband and the second subband are composed of one or more continuous frequency domain resource units or multiple discontinuous frequency domain resource units. The frequency domain resource unit includes one or more of a subcarrier, a subcarrier set / group, an RB, an RB group, etc. The number of subcarriers included in the subcarrier group is or is not a multiple of the number of subcarriers included in an RB, for example, the number of subcarriers included in the subcarrier group is less than the number of subcarriers included in one RB, but is not limited thereto. The RB group, for example, includes multiple RBs.

[0088] For example, if a frequency domain resource unit includes a subcarrier, a subcarrier group, an RB, or one of the RB groups, and the one is an RB, then the first subband includes one or more consecutive RBs or multiple discontinuous RBs. For another example, if a frequency domain resource unit includes a subcarrier and an RB, then the first subband may include an integer number of RBs and an integer number of subcarriers, and the integer number of RBs and the integer number of subcarriers may be consecutive or discontinuous.

[0089] In some embodiments, the number of frequency-domain resource units included in the third subband and / or the first subband and / or the second subband is (must be) a multiple of N1 and / or a common multiple of N2, N3, and N4. For example, N1 = 2 or 4, N2 = 2, N3 = 3, N4 = 5, or other values, without limitation.

[0090] In some embodiments, the first subband may also be referred to as an uplink subband (UL subband), or an uplink SBFD subband, or an SBFD uplink subband, or an uplink RB set (i.e., an RB set for uplink), or an uplink SBFD RB set, or an SBFD uplink RB set. The embodiments of the present application are not limited to this.

[0091] In some embodiments, the second subband may also be referred to as a downlink subband (DL subband), or a downlink SBFD subband, or a SBFD downlink subband, or a downlink RB set (i.e., an RB set for downlink), or a downlink SBFD RB set, or a SBFD downlink RB set. The embodiments of the present application are not limited to this.

[0092] In some embodiments, there is no third subband or no third subband (GB) between the first subband (e.g., UL subband) and the second subband (e.g., DL subband). For one carrier, at most one first subband is configured. Figure 8 is a schematic diagram of the subband pattern of an embodiment of the present application. As shown in Figure 8, for one carrier, one first subband is configured respectively. As shown in (a), (b) and (c) in Figure 8, there is a third subband between the first subband and the second subband. As shown in (d), (e) and (f) in Figure 8, there is no third subband between the first subband and the second subband. This is only an example, and the embodiments of the present application are not limited to this.

[0093] The first to fourth indication information are described below.

[0094] In some embodiments, the first indication information and / or the second indication information is cell-specific (or public) or UE-specific (or dedicated), for example, the first indication information is cell-specific and the second indication information is UE-specific. The third indication information and / or the fourth indication information is cell-specific (or public) or UE-specific (or dedicated).

[0095] In some embodiments, cell-specific means that the parameter settings for different UEs in the cell are the same (for example, broadcast through system information or sent through dedicated RRC signaling but the content sent for different UEs is the same), and UE-specific means that the parameter settings for different UEs in the cell may be different (for example, sent through dedicated RRC signaling and the content sent for different UEs may be the same or different). For example, if the indication information includes an IE of indication information included in an IE or message dedicated to configuring cell-specific parameters, it indicates that the indication information is cell-specific. If the indication information includes an IE of indication information included in an IE or message dedicated to configuring UE specific / dedicated parameters, it indicates that the indication information is UE-specific. However, the present invention is not limited to this. In some cases, even if the indication information is included in a UE specific / dedicated IE or message, it may be cell-specific. For example, the indication information is included in a system message and / or a public service cell configuration, and the indication information is included in a dedicated RRC message and / or a serving cell configuration.

[0096] In some embodiments, the third indication information is, for example, initialDownlinkBWP (used to configure the initial DL BWP) or downlinkBWP-ToAddModList (used to configure one or more additional DL BWPs). The downlinkBWP-ToAddModList includes one or more BWP-Downlinks, and one BWP-Downlink is used to configure one DL BWP. In other words, a DL BWP is configured by initialDownlinkBWP or one BWP-Downlink. For a DL BWP configured by initialDownlinkBWP, i.e., the initial DL BWP, its BWP ID defaults to 0. For a DL BWP configured by BWP-Downlink, the corresponding BWP-Downlink includes information indicating the BWP ID of the DL BWP. initialDownlinkBWP and BWP-Downlink may include BWP-DownlinkCommon and BWP-DownlinkDedicated, respectively. BWP-DownlinkCommon is used to configure common parameters (or cell-specific parameters) of the corresponding DL BWP, while BWP-DownlinkDedicated is used to configure UE-specific parameters of the corresponding DL BWP.

[0097] In some embodiments, the fourth indication information is, for example, initialUplinkBWP (used to configure an initial UL BWP) or uplinkBWP-ToAddModList (used to configure one or more additional UL BWPs. The uplinkBWP-ToAddModList includes one or more BWP-Uplinks, and one BWP-Uplink is used to configure one UL BWP. In other words, a UL BWP is configured by initialUplinkBWP or one BWP-Uplink. Among them, for a UL BWP configured by initialUplinkBWP, that is, an initial UL BWP, its BWP ID defaults to 0. For a DL BWP configured by BWP-Uplink, the corresponding BWP-Uplink includes information indicating the BWP ID of the UL BWP. initialUplinkBWP and BWP-Uplink may respectively include BWP-UplinkCommon and BWP-UplinkDedicated, BWP-UplinkCommon is used to configure the common parameters (or cell-specific parameters) of the corresponding UL BWP, and BWP-UplinkDedicated is used to configure the UE-specific parameters of the corresponding UL BWP.

[0098] In some embodiments, BWP-DownlinkCommon and BWP-UplinkCommon respectively include BWP IE, which is used to configure general parameters of the corresponding BWP, such as the locationAndBandwidth field for configuring the frequency domain location and bandwidth of the BWP, the subcarrierSpacing field for configuring the SCS used by the BWP, and the cyclicPrefix field for configuring whether the BWP uses Extended CP (ECP). The locationAndBandwidth field includes, for example, a resource indicator value (RIV), where RIV is the starting value of the BWP. and bandwidth L RBs Jointly mapped / encoded to a value, a RIV corresponds to a starting RB and the number / length L of consecutive RBs RBs RIV is defined, for example, as follows: but

[0099] otherwise

[0100] Among them, L RBs ≥1 and cannot exceed For example is a (predefined or predefined) integer, e.g. The first PRB is determined by the subcarrierSpacing of the BWP and the offsetToCarrier of the corresponding SCS (configured in SCS-SpecificCarrier contained within FrequencyInfoDL / FrequencyInfoUL / FrequencyInfoUL-SIB / FrequencyInfoDL-SIB within ServingCellConfigCommon / ServingCellConfigCommonSIB). That is, the locationAndBandwidth field indicates the starting RB and number of RBs of the BWP (using the SCS provided by subcarrierSpacing) based on the frequency position of the SCS provided by subcarrierSpacing relative to the frequency position provided by offsetToCarrier. If The BWP includes the RB corresponding to offsetToCarrier (ie, the first RB of the SCS specific carrier). The cyclicPrefix field is optional. When it is not present, the Normal CP (NCP) is used by default.

[0101] In some embodiments, initialDownlinkBWP and initialUplinkBWP are included in SIB1 or in the public service cell configuration ServingCellConfigCommon or in the serving cell configuration ServingCellConfig, initialDownlinkBWP and initialUplinkBWP included in SIB1 or ServingCellConfigCommon include only BWP-DownlinkCommon and BWP-UplinkCommon, respectively, and initialDownlinkBWP and initialUplinkBWP included in SIB1 or ServingCellConfig include only BWP-DownlinkDedicated and BWP-UplinkDedicated, respectively. downlinkBWP-ToAddModList and uplinkBWP-ToAddModList are included in the serving cell configuration ServingCellConfig.

The first indication information and the second indication information are carried by the same or different signaling or messages or information elements IE.

[0130] In some embodiments, the first indication information and / or the second indication information includes one or more first configurations.

[0131] In some embodiments, the first indication information and / or the second indication information is, for example, a list of (may include one or more) first configurations, the first configuration including a first information unit and / or one or more information fields (for indicating the frequency domain position of the first subband).

[0132] In some embodiments, the first configuration includes information (or information fields) indicating one or more of the following: the frequency domain location (starting and / or ending and / or center and / or bandwidth) of one or a group of first subbands; the frequency domain location (starting and / or ending and / or center and / or bandwidth) of one or a group of second subbands; the frequency domain location (starting and / or ending and / or center and / or bandwidth) of one or a group of third subbands; an index; a subcarrier spacing; and a reference point.

The third index is used to identify or indicate the (downlink and / or uplink) BWP associated with the configuration. The third index may be a BWP ID. For example, the first configuration includes a first index and a second index, and may indicate the first subband and / or the second subband and / or the third subband identified by the first index on the SCS specific carrier identified by the second index (or, in other words, the first configuration is identified by the first index and is for the (downlink and / or uplink) SCS specific carrier identified by the second index and / or the (downlink and / or uplink) BWP corresponding to the SCS specific carrier); or, for example, the first configuration includes a first index and a third index, and may indicate the first subband and / or the second subband and / or the third subband identified by the first index on the BWP identified by the third index (or, in other words, the first configuration is identified by the first index and is for the (downlink and / or uplink) or, for example, the first configuration includes a first index, a second index and a third index, then it may indicate the first subband and / or the second subband and / or the third subband identified by the first index on the frequency domain resources where the BWP identified by the third index overlaps with the SCS specific carrier identified by the second index (or in other words, the first configuration is identified by the first index and is for the (downlink and / or uplink) SCS specific carrier identified by the second index and the (downlink and / or uplink) BWP identified by the third index, the SCS specific carrier and the BWP have the same SCS and / or the BWP is within the SCS specific carrier). Examples are not given one by one here.

[0133] In some embodiments, the first subband, the second subband, and / or the third subband are configured for a cell, a (DL and / or UL) SCS specific carrier, or a (DL and / or UL) BWP. For example, the first indication information and / or the second indication information configure the first subband, the second subband, and / or the third subband for a cell, a (DL and / or UL) SCS specific carrier, or a (DL and / or UL) BWP. For example, being configured for a cell means that the configured first subband, the second subband, and / or the third subband are applicable to different SCS specific carriers and / or BWPs in the cell. For a (DL and / or UL) SCS specific carrier, it means that the configured first subband and / or second subband and / or third subband are applicable to their associated / corresponding (DL and / or UL) SCS specific carriers, and thus also to the (DL and / or UL) BWP corresponding to the (DL and / or UL) SCS specific carriers. For example, corresponding first subbands and / or second subbands and / or third subbands are respectively configured for different SCSs or different (DL and / or UL) SCS specific carriers in a cell. For a (DL and / or UL) BWP, it means, for example, that the configured first subband and / or second subband and / or third subband are applicable to their associated / corresponding (DL and / or UL) BWPs. For example, corresponding first subbands and / or second subbands and / or third subbands are respectively configured for different (DL and / or UL) BWPs in a cell.

[0134] In some embodiments, the DL BWP corresponds to / is associated with the DL SCS specific carrier that is the same as its SCS and / or the UL SCS specific carrier that is the same as the SCS of the UL BWP associated with it, and the UL BWP corresponds to / is associated with the UL SCS specific carrier that is the same as its SCS and / or the DL SCS specific carrier that is the same as the SCS of the DL BWP associated with it.

[0135] In some embodiments, the first indication information and / or the second indication information indicates the first subband and / or the second subband and / or the third subband for the cell, and the UE determines the first subband and / or the second subband and / or the third subband for the (DL and / or UL) SCS specific carrier and / or the (DL and / or UL) BWP based on the indicated first subband and / or the second subband and / or the third subband.

[0136] In some embodiments, the first indication information and / or the second indication information indicates the first subband and / or the second subband and / or the third subband for the (DL and / or UL) SCS specific carrier, and the UE determines the first subband and / or the second subband and / or the third subband for the (DL and / or UL) BWP based on the indicated first subband and / or the second subband and / or the third subband.

[0137] In some embodiments, the first indication information and / or the second indication information indicates the first subband and / or the second subband and / or the third subband for the DL SCS specific carrier, and the UE determines the first subband and / or the second subband and / or the third subband for the (associated) UL SCS specific carrier and / or the (DL and / or UL) BWP based on the indicated first subband and / or the second subband and / or the third subband.

[0138] In some embodiments, the first indication information and / or the second indication information indicates the first subband and / or the second subband and / or the third subband for the UL SCS specific carrier, and the UE determines the first subband and / or the second subband and / or the third subband for the (associated) DL SCS specific carrier and / or the (DL and / or UL) BWP based on the indicated first subband and / or the second subband and / or the third subband.

[0139] In some embodiments, assuming that the first subband and / or the second subband and / or the third subband are configured for a DL SCS specific carrier, for a DL BWP, the UE determines the overlapping relationship between the frequency domain resources therein and these subbands based on the first subband and / or the second subband and / or the third subband of the DL SCS specific carrier corresponding to the DL BWP. For a UL BWP, the UE determines the overlapping relationship between the frequency domain resources therein and these subbands based on the first subband and / or the second subband and / or the third subband of the DL SCS specific carrier corresponding to the DL BWP; or, the UE determines the overlapping relationship between the frequency domain resources therein and these subbands based on the first subband and / or the second subband and / or the third subband of the UL SCS specific carrier corresponding to the UL BWP, wherein the first subband and / or the second subband and / or the third subband of the UL SCS specific carrier are determined based on the first subband and / or the second subband and / or the third subband of the DL SCS specific carrier corresponding to the UL BWP.

[0140] In some embodiments, when determining the subbands in another SCS specific carrier or BWP based on an SCS specific carrier, the starting or ending RB of the first subband and / or the second subband and / or the third subband of the one SCS specific carrier must be the same as the starting or ending position of an RB in the other SCS specific carrier or BWP, as shown in (a) and (c) of FIG. 11. Alternatively, if the starting or ending position of the starting or ending RB of the first subband and / or the second subband and / or the third subband of the one SCS specific carrier is within an RB in the other SCS specific carrier or BWP (that is, between the start and end of the RB), the RB belongs to the first subband, the second subband, or the third subband for the other SCS specific carrier or BWP, as shown in (b), (d), (e), and (f) of FIG. This is described below with reference to FIG. 11. As shown in Figure 11, in (b) and (d), for example, the first subband and / or the second subband and / or the third subband are configured for the downlink SCS specific carrier. For the DL BWP, find the downlink SCS specific carrier with the same SCS as its SCS, and then determine the corresponding first subband and / or second subband and / or third subband, that is, these subbands in the downlink SCS specific carrier. For the uplink BWP, first find the DL BWP associated with the UL BWP, and then find the downlink SCS specific carrier with the same SCS as the DL BWP, and then determine that the first subband and / or second subband and / or third subband corresponding to the UL BWP are these subbands in the downlink SCS specific carrier. Alternatively, the UE determines the first subband and / or second subband and / or third subband in the UL SCS specific carrier corresponding to the UL BWP based on these subbands in the downlink SCS specific carrier, and the UL BWP corresponds to these subbands in the UL SCS specific carrier. In (a)(c)(e)(f), for example, the first subband and / or the second subband and / or the third subband are configured for the downlink SCS specific carrier and / or the UL SCS specific carrier, and the uplink and downlink BWPs respectively determine the corresponding first subband and / or second subband and / or third subband, i.e., the subband in the corresponding SCS specific carrier, according to their respective corresponding SCS specific carriers. As shown in (e)(f), the downlink BWP and the subband corresponding to the uplink BWP are not aligned.

[0141] In some embodiments, the correspondence between the DL BWP and / or UL BWP and the first subband and / or the second subband and / or the third subband may be determined according to a rule and / or indication (explicit or implicit indication).

[0142] As an implementation method, the correspondence between the DL BWP and / or UL BWP and the first subband and / or the second subband and / or the third subband can be determined according to rules. For example, assuming that the first subband and / or the second subband and / or the third subband are configured for a DL SCS specific carrier, for the DL BWP, the UE determines the DL SCS specific carrier corresponding to the DL BWP, thereby determining the first subband and / or the second subband and / or the third subband configured for the DL SCS specific carrier. Assuming that the first subband and / or the second subband and / or the third subband are configured for the DL BWP, the first subband and / or the second subband and / or the third subband corresponding to the DL BWP can be directly determined, and the BWP and the corresponding subband can have the same SCS.

[0143] As an implementation, the terminal device may further receive fifth indication information, where the fifth indication information is used to indicate a correspondence between a DL BWP and / or UL BWP and the first subband and / or the second subband and / or the third subband. The first indication information and / or the second indication information and / or the third indication information and / or the fourth indication information may include the fifth indication information. For example, the first indication information and / or the second indication information may include the fifth indication information, and the fifth indication information may be information indicating a BWP identifier (BWP ID). When the first indication information and / or the second indication information includes the information indicating the BWP identifier (BWP ID), it indicates that the first subband and / or the second subband and / or the third subband indicated by the first indication information and / or the second indication information corresponds to the DL BWP and / or the UL BWP corresponding to the indicated BWP ID. For another example, the first indication information and / or the second indication information includes one or more first configurations, the first configuration including information for indicating a BWP identifier (BWP ID), indicating that the first subband and / or the second subband and / or the third subband indicated by the first configuration corresponds to the DL BWP and / or the UL BWP corresponding to the indicated BWP ID. For another example, the third indication information and / or the fourth indication information may include fifth indication information, the fifth indication information may be an index (e.g., a third index) for indicating the resource configuration of the first subband and / or the second subband and / or the third subband. When the third indication information and / or the fourth indication information includes the index, it indicates that the DL BWP and / or the UL BWP configured by the third indication information and / or the fourth indication information corresponds to the first subband and / or the second subband and / or the third subband corresponding to the index. Examples are not given one by one here.

[0144] As an implementation method, the third indication information and / or the fourth indication information includes the first indication information and / or the second indication information, indicating that the DL BWP and / or UL BWP configured by the third indication information and / or the fourth indication information corresponds to the first subband and / or the second subband and / or the third subband indicated by the first indication information and / or the second indication information.

[0145] The above implementation methods can be implemented independently or in combination, and the embodiments of the present application are not limited thereto.

[0146] The first DL BWP and the first UL BWP are described below.

[0147] In some embodiments, the first DL BWP may be the currently activated DL BWP in the BWP indicated by the third indication information, and / or the first UL BWP may be the currently activated UL BWP in the BWP indicated by the fourth indication information, but the present application is not limited thereto.

[0148] In some embodiments, the first DL BWP includes or excludes first frequency domain resources that overlap with (the third frequency domain resources of) the second subband; for example, the first DL BWP must include at least one first frequency domain resource that overlaps with (the third frequency domain resources of) the second subband, or in other words, the terminal device expects the first DL BWP to include at least one first frequency domain resource that overlaps with (the third frequency domain resources of) the second subband, or in other words, the terminal device does not expect the first DL BWP to exclude first frequency domain resources that overlap with (the third frequency domain resources of) the second subband. For example, (b), (c), (d), and (e) in FIG10D are all subband patterns that do not support configuration. Or, for example, the first DL BWP may not include first frequency domain resources that overlap with (the third frequency domain resources of) the second subband. In addition, the first DL BWP may also include or exclude first frequency domain resources that overlap with (the fourth frequency domain resources of) the first subband and / or (the fifth frequency domain resources of) the third subband.

[0149] In some embodiments, the start and / or end of the first DL BWP (respectively) are within or outside the third sub-band, or in other words, the start and / or end of the first DL BWP are aligned or not aligned with the start and / or end of the third sub-band in the frequency domain; for example, the start and / or end of the first DL BWP (respectively) must not be within the third sub-band, or in other words, the terminal device expects the start and / or end of the first DL BWP (respectively) not to be within the third sub-band, or in other words, the terminal device does not expect the start and / or end of the first DL BWP (respectively) to be within the third sub-band, such as (c) and (d) in FIG10B , which are sub-band patterns that do not support configuration. Alternatively, for example, the start and / or end of the first DL BWP (respectively) may be within the third sub-band.

[0150] In some embodiments, the start and / or end of the first DL BWP (respectively) are within or outside the first subband and / or second subband, or in other words, the start and / or end of the first DL BWP are aligned or not aligned with the start and / or end of the first subband and / or second subband in the frequency domain; for example, the start and / or end of the first DL BWP (respectively) must not be within the first subband and / or second subband, or in other words, the terminal device expects the start and / or end of the first DL BWP (respectively) not to be within the first subband and / or second subband, or in other words, the terminal device does not expect the start and / or end of the first DL BWP (respectively) to be within the first subband and / or second subband, such as (g) and (h) in FIG. 10B and (b) in FIG. 10C , which are subband patterns that do not support configuration. Alternatively, for example, the start and / or end of the first DL BWP (respectively) may be within the first subband and / or second subband.

[0151] In some embodiments, the first UL BWP includes or does not include a second frequency domain resource that overlaps with (the fourth frequency domain resource of) the first subband; for example, the first UL BWP must include at least one second frequency domain resource that overlaps with (the fourth frequency domain resource of) the first subband, or in other words, the terminal device expects the first UL BWP to include at least one second frequency domain resource that overlaps with (the fourth frequency domain resource of) the first subband, or in other words, the terminal device does not expect the first UL BWP to not include at least one second frequency domain resource that overlaps with (the fourth frequency domain resource of) the first subband. For example, (a), (c), (e), and (g) in FIG10C are all subband patterns that do not support configuration. For example, the first UL BWP may not include a second frequency domain resource that overlaps with (the fourth frequency domain resource of) the first subband. In addition, the first UL BWP may also include or not include a second frequency domain resource that overlaps with (the third frequency domain resource of) the second subband and / or (the fifth frequency domain resource of) the third subband.

[0152] In some embodiments, the start and / or end of the first UL BWP (respectively) are within or outside the third sub-band, or in other words, the start and / or end of the first UL BWP are aligned or not aligned with the start and / or end of the third sub-band in the frequency domain; for example, the start and / or end of the first UL BWP (respectively) must not be within the third sub-band, or in other words, the terminal device expects the start and / or end of the first UL BWP (respectively) not to be within the third sub-band, or in other words, the terminal device does not expect the start and / or end of the first UL BWP (respectively) to be within the third sub-band, such as (c) and (d) in FIG10B , which are sub-band patterns that do not support configuration. Alternatively, for example, the start and / or end of the first UL BWP (respectively) may be within the third sub-band.

[0153] In some embodiments, the start and / or end of the first UL BWP (respectively) are within or outside the first subband and / or second subband, or in other words, the start and / or end of the first UL BWP are aligned or not aligned with the start and / or end of the first subband and / or second subband in the frequency domain; for example, the start and / or end of the first UL BWP (respectively) must not be within the first subband and / or second subband, or in other words, the terminal device expects the start and / or end of the first UL BWP (respectively) not to be within the first subband and / or second subband, or in other words, the terminal device does not expect the start and / or end of the first UL BWP (respectively) to be within the first subband and / or second subband, such as (g) and (h) in FIG. 10B and (b) in FIG. 10C , which are subband patterns that do not support configuration. Alternatively, for example, the start and / or end of the first UL BWP (respectively) may be within the first subband and / or second subband.

[0154] In some embodiments, the centers (frequencies (positions)) and / or BWP IDs of corresponding DL BWPs and UL BWPs (also referred to as a pair of downlink BWPs and uplink BWPs) are the same. For example, the centers (frequencies (positions)) and / or BWP IDs of the first UL BWP and the first DL BWP are the same, or the centers (frequencies (positions)) and / or BWP IDs of the second UL BWP and the second DL BWP described later are the same.

[0155] In some embodiments, the SCS of the corresponding first DL BWP and the first UL BWP (also referred to as a pair of downlink BWP and uplink BWP) (must) be the same or (may) be different, the starting (frequency (position)) (must) be the same or (may) be different, and the ending (frequency (position)) (must) be the same or (may) be different. For example, the terminal device expects that the SCS of the corresponding first DL BWP and the first UL BWP are the same, the starting (frequency (position)) are the same, and the ending (frequency (position)) are the same.

[0156] The following is a schematic diagram of DL BWP and / or UL BWP and SCS specific carriers and the subbands thereon, with reference to the accompanying drawings. In the following examples, a pair of downlink SCS specific carriers and uplink SCS specific carriers in Figures 10A to 10E have the same SCS, but can also be different SCSs. In addition, the subbands can be the same SCS or different SCSs. The uplink and downlink BWPs and specific carriers and the corresponding first subbands can be aligned or not aligned. In addition, GB in the figure represents the third subband, GB with SCS1 represents GB based on SCS1, UL subband with SCS1 represents the first subband based on SCS1, and DL subband with SCS1 represents the second subband based on SCS1.

[0157] As shown in Figure 10A, the BWP is aligned with the carrier, and the uplink and downlink BWP center frequencies are aligned. In (a), the DL BWP has (completely) overlapping resources with the first subband, the second subband, and the third subband, but there is no corresponding subband on the UL BWP, that is, there are no overlapping resources with the first subband, the second subband, and the third subband.

In (c), both the DL BWP and the UL BWP have overlapping resources with the first subband, the second subband, and the third subband.

[0158] As shown in Figure 10B, the BWP differs from the start and / or end of the carrier, and the uplink and downlink BWP center frequencies are aligned. In (a) and (b), the DL BWP has (partially) overlapping resources with the first, second, and third subbands. The UL BWP has overlapping resources with the first and third subbands, but not the second subband, and the BWP starts, ends, and / or is not centered within the subband and / or the third subband. In (c) to (h), unlike (a) and (b), the BWP starts, ends, and / or is centered within the subband and / or the third subband.

[0159] As shown in Figure 10C, the BWP differs from the start and / or end of the carrier, and the uplink and downlink BWP center frequencies are aligned. In (a), the DL BWP has (partially) overlapping resources with both the second and third subbands, and the UL BWP has overlapping resources with the third subband, but excludes the second and first subbands, and the BWP starts, ends, and / or is not centered within the subband and / or the third subband. In (e) and (f), the DL BWP has (completely) overlapping resources with the second subband, and the UL BWP excludes the second, first, and third subbands, and the BWP starts, ends, and / or is not centered within the subband and / or the third subband. In (b), (c), (d), (f), and (h), the BWP starts, ends, and / or is centered within the subband and / or the third subband. In addition, in (b), the DL BWP has (partially) overlapping resources with the second subband, the third subband, and the first subband, and the UL BWP has overlapping resources with the first subband and the third subband, but does not include the second subband. In (c) and (d), the DL BWP has (partially) overlapping resources with the second subband and the third subband, and the UL BWP has (partially) overlapping resources with the third subband, but does not include the second subband and the first subband. In (g) and (h), the DL BWP has (partially) overlapping resources with the second subband, and the UL BWP does not include the second subband, the first subband, and the third subband.

[0160] As shown in Figure 10D, the BWP and the carrier start and / or end are different, and the uplink and downlink BWP center frequencies are aligned. In (a), the DL BWP has (partially) overlapping resources with the second subband, the UL BWP does not include the second subband, the first subband, and the third subband, and the BWP starts, ends, and / or is centered within the subband.

[0161] As shown in Figure 10E , the BWP starts and / or ends at different locations from the carrier, and the uplink and downlink BWP center frequencies are aligned. The DL BWP includes resources overlapping with the first, second, and third subbands, while the UL BWP includes resources overlapping with the first and third subbands. In (a), the BWP starts, ends, and / or is centered within the subband; in (b), the BWP starts, ends, and / or is centered outside the subband or the third subband.

[0162] In some embodiments, whether to employ SBFD in a DL BWP and / or UL BWP can be determined based on rules and / or instructions. The first DL BWP and / or first UL BWP described above can be considered a BWP that employs SBFD, determined based on rules and / or instructions. The second DL BWP and / or second UL BWP described below is a BWP that does not employ SBFD, determined based on rules and / or instructions. The frequency domain relationship between the second DL BWP and / or second UL BWP and the first subband, / or second subband, and / or third subband is similar to that between the first DL BWP and / or first UL BWP and the first subband, / or second subband, and / or third subband. However, the processing of transmitted and received signals on the corresponding time and frequency domain resources may differ. In other words, the frequency domain resources of the second DL BWP and / or second UL BWP and the first DL BWP and / or first UL BWP (available for transmitting and receiving signals) differ on different time domain resources.

[0163] In some embodiments, for a DL / UL BWP, if the above-mentioned position relationship requirement between the first DL / UL BWP and the subband is not met, it belongs to the second DL / UL BWP.

[0164] In some embodiments, if a DL BWP does not overlap with the first subband, it belongs to the second DL BWP, and / or if a UL BWP does not overlap with the first subband, it belongs to the second UL BWP. Alternatively, if a pair of DL BWP and UL BWP does not overlap with the first subband, the pair of DL BWP and UL BWP belongs to the second DL BWP and the second UL BWP, respectively.

[0165] In some embodiments, the DL / UL BWP defaults to the second DL / UL BWP, for example, the initial DL BWP and / or the initial UL BWP belongs to / is the second UL BWP by default.

[0166] As an implementation method, the terminal device may receive the sixth indication information, where the sixth indication information is used to indicate whether SBFD operation is adopted in one or more DL BWPs and / or UL BWPs, and the fifth indication information is UE-specific, cell-specific, carrier-specific, or BWP-specific. The third indication information and / or the fourth indication information includes the sixth indication information, and / or the sixth indication information includes information indicating a BWP ID. The BWP indicated by the sixth indication information is a BWP adopting SBFD operation, and vice versa. This embodiment of the present application is not limited to this.

[0167] The following describes how the terminal device receives or sends signals on the above-mentioned BWP. The following first time domain resources and / or second time domain resources may be indicated first time domain resources and / or second time domain resources or actual first time domain resources and / or second time domain resources, and may be indicated based on the first SCS and / or first CP, or determined based on the second SCS and / or second CP. The first SCS and the second SCS may be the same or different, and the first CP and / or the second CP may be a normal cyclic prefix normal CP and / or an extended cyclic prefix extended CP. The embodiments of the present application are not limited to this. The following "first subband", "second subband" and "third subband" refer to the subbands corresponding to the BWP. How to determine the corresponding relationship is as described above and will not be repeated here.

[0168] For DL ​​BWP:

[0169] In some embodiments, for / in the first time domain resources, only the first frequency domain resources overlapping with the second subband in the first DL BWP are used to receive downlink signals, or in other words, the terminal device can receive downlink signals in the first frequency domain resources (only) overlapping with the second subband (the third frequency domain resources) in the first DL BWP, wherein, when the activated DL BWP is the first DL BWP, only the first frequency domain resources overlapping with the second subband (the third frequency domain resources) in the first DL BWP are allowed / can receive downlink signals.

[0170] In some embodiments, if the first DL BWP does not include a first frequency domain resource overlapping with (the third frequency domain resource of) the second sub-band, the terminal device does not receive a downlink signal in the first time domain resource.

[0171] In some embodiments, for / in the first time domain resources, the first frequency domain resources in the first DL BWP that overlap with the first subband (the fourth frequency domain resources) and / or the third subband (the fifth frequency domain resources) are not used to receive downlink signals, that is, the terminal device does not receive downlink signals in the first frequency domain resources in the first DL BWP that overlap with the first subband (the fourth frequency domain resources) and / or the third subband (the fifth frequency domain resources).

[0172] In some embodiments, for / in the second time domain resources, the terminal device can receive downlink signals in the first frequency domain resources overlapping with the first sub-band (the fourth frequency domain resources) and / or the third sub-band (the fifth frequency domain resources) in the first DL BWP, and can also receive downlink signals in the first frequency domain resources overlapping with the second sub-band (the third frequency domain resources), that is, the first DL BWP can be used to receive downlink signals. That is, if the first DL BWP includes resources overlapping with the first sub-band, the second sub-band, and the third sub-band, in the first time domain resources, downlink signals are received only in the first frequency domain resources overlapping with the second sub-band (the third frequency domain resources), and downlink signals are not received in the first frequency domain resources overlapping with the first sub-band (the fourth frequency domain resources) and / or the third sub-band (the fifth frequency domain resources). However, in the second time domain resource, the downlink signal can be received in the first frequency domain resource overlapping with the first subband (the fourth frequency domain resource) and / or the third subband (the fifth frequency domain resource), and of course, the downlink signal can also be received in the first frequency domain resource overlapping with the second subband (the third frequency domain resource).

[0173] In some embodiments, for / in the second time domain resource, the terminal device may determine, according to a rule and / or indication (explicitly or implicitly), whether to receive a downlink signal in the first frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first DL BWP. As an implementation, when the first indication information and / or the second indication information is cell-specific, it is determined that the first frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first DL BWP receives a downlink signal. When the first indication information and / or the second indication information is UE-specific, it is determined that the first frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first DL BWP does not receive a downlink signal. As an implementation, the terminal device may further receive ninth indication information, which is used to indicate whether to receive a downlink signal in the first frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first DL BWP. The ninth indication information may be 1-bit indication information, and the value of the bit is used to determine whether to receive a downlink signal in the first frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first DL BWP.

[0174] In the above embodiment, in other words, on different time domain resources (for example, the first time domain resource and the second time domain resource), the frequency domain resources that can be used to obtain the downlink signal of the first DL BWP are different. For example, on the first time domain resource, the first DL BWP does not include the first frequency domain resource that overlaps with the first subband (the fourth frequency domain resource) and / or the third subband (the fifth frequency domain resource). On the second time domain resource, the frequency domain resources of the first DL BWP can be used to receive downlink signals.

[0175] In some embodiments, for / on the second time domain resources, the terminal device receives a downlink signal on the first frequency domain resources overlapping with (the fourth frequency domain resources of) the first sub-band in the second DL BWP, wherein the second time domain resources and / or the second DL BWP do not support SBFD operation. Therefore, the terminal device can receive the downlink signal on the first frequency domain resources overlapping with (the fourth frequency domain resources of) the first sub-band in the second DL BWP on the second time domain resources, and of course can also receive the downlink signal on frequency domain resources other than the first sub-band. In other words, on different time domain resources (e.g., the first time domain resources and the second time domain resources), the available frequency domain resources of the first DL BWP and the second DL BWP are different. For example, on the first time domain resources, the first DL BWP does not include the first frequency domain resources overlapping with (the fourth frequency domain resources of) the first sub-band and / or (the fifth frequency domain resources of) the third sub-band. On the second time domain resources, all frequency domain resources of the second DL BWP can be used to receive downlink signals.

[0176] For UL BWP:

[0177] In some embodiments, for / in the second time domain resources, only the second frequency domain resources in the first UL BWP that overlap with the first subband are used to send uplink signals, or in other words, the terminal device can send uplink signals in the first UL BWP using the second frequency domain resources that (only) overlap with (the fourth frequency domain resources of) the first subband, wherein, when the activated UL BWP is the first UL BWP, only the second frequency domain resources that (only) overlap with (the fourth frequency domain resources of) the first subband are allowed / can be used in the first UL BWP to send uplink signals.

[0178] In some embodiments, if the first UL BWP does not include a second frequency domain resource overlapping with (the fourth frequency domain resource of) the first subband, the terminal device does not send an uplink signal in the second time domain resource.

[0179] In some embodiments, for / in the first time domain resources, the second frequency domain resources in the first UL BWP that overlap with the second subband (the third frequency domain resources) and / or the third subband (the fifth frequency domain resources) are not used to send uplink signals, that is, the terminal device does not send uplink signals in the first UL BWP using the second frequency domain resources that overlap with the second subband (the third frequency domain resources) and / or the third subband (the fifth frequency domain resources).

[0180] In some embodiments, for / in the second time domain resources, the terminal device may send an uplink signal in the first UL BWP using the second frequency domain resources overlapping with the second sub-band (the third frequency domain resources) and / or the third sub-band (the fifth frequency domain resources), and may also send an uplink signal in the first frequency domain resources overlapping with the first sub-band (the fourth frequency domain resources), that is, the first UL BWP can be used to send an uplink signal. That is, if the first UL BWP includes resources overlapping with the first sub-band, the second sub-band, and the third sub-band, in the first time domain resources, uplink signals are sent only in the second frequency domain resources overlapping with the first sub-band (the fourth frequency domain resources), and no uplink signals are sent in the second frequency domain resources overlapping with the second sub-band (the third frequency domain resources) and / or the third sub-band (the fifth frequency domain resources). However, in the second time domain resource, an uplink signal can be sent in the second frequency domain resource overlapping with the second subband (the third frequency domain resource) and / or the third subband (the fifth frequency domain resource). Of course, an uplink signal can also be sent in the second frequency domain resource overlapping with the first subband (the fourth frequency domain resource).

[0181] In some embodiments, for / in the second time domain resource, the terminal device may determine, according to rules and / or indications (explicitly or implicitly), whether to send an uplink signal in the second frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first UL BWP. As an implementation manner, when the first indication information and / or the second indication information is cell-specific, it is determined that the uplink signal is sent in the second frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first UL BWP; and when the first indication information and / or the second indication information is UE-specific, it is determined not to send an uplink signal in the second frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first UL BWP. As an implementation manner, the terminal device may further receive ninth indication information, which is used to indicate whether to send an uplink signal in the second frequency domain resource overlapping with the third subband (the fifth frequency domain resource) in the first UL BWP. The implementation manner of the ninth indication information is not repeated here.

[0182] In the above embodiment, in other words, on different time domain resources (for example, the first time domain resource and the second time domain resource), the frequency domain resources of the first UL BWP are different. For example, on the second time domain resource, the first UL BWP does not include the second frequency domain resource that overlaps with the second subband (the third frequency domain resource) and / or the third subband (the fifth frequency domain resource). On the second time domain resource, the frequency domain resources of the first UL BWP can be used to send uplink signals.

[0183] In some embodiments, for / in the second time domain resource, the terminal device does not send an uplink signal in the second UL BWP, or the terminal device sends an uplink signal in the second frequency domain resource where the second UL BWP overlaps with the second subband (the third frequency domain resource), wherein the second time domain resource and / or the second UL BWP does not support SBFD operation, therefore, the terminal device is on the second time domain resource, the terminal device does not send an uplink signal in the second UL BWP, or the terminal device sends an uplink signal in the second frequency domain resource where the second UL BWP overlaps with the second subband (the third frequency domain resource). In other words, on different time domain resources (for example, the first time domain resources and the second time domain resources), the usable frequency domain resources of the first UL BWP and the second UL BWP are different. For example, on the first time domain resources, the first UL BWP does not include the second frequency domain resources that overlap with the second subband (the third frequency domain resources) and / or the third subband (the fifth frequency domain resources). On the second time domain resources, the frequency domain resources of the second UL BWP can be used to send uplink signals, or uplink signals are not sent in the second UL BWP (depending on the configuration of the seventh indication information and the eighth indication information).

[0184] The overlap involved in the above embodiments includes partial overlap and / or complete overlap. It should be noted that the first time domain resource and the second time domain resource are time domain resources at different locations, and the first frequency domain resource and the second frequency domain resource are frequency domain resources at different locations.
