Description

Resource indication method, device, equipment, system and storage medium

Technical Field

Background

In the New air interface (NR), the network side may configure a Bandwidth Part (BWP) for a User Equipment (UE) to perform data transmission. To accommodate traffic needs, BWP may be configured dynamically for traffic. For uplink and downlink transmission, the network side can configure different transmission directions for different subbands of the frequency domain resource to realize that at the same time, uplink transmission and downlink transmission exist, and uplink and downlink transmission exist on different subbands, namely, the existing resource indication scheme indicates the transmission directions of the time domain and the frequency domain of each subband simultaneously after non-overlapping subbands are configured on BWP.

However, since the configuration of the subbands may not meet the requirement of the uplink and downlink BWP (BWP pair) for the central carrier frequency of the time division duplex (Time Division Duplexing, TDD) (i.e., the requirement of the uplink and downlink BWP for the central carrier frequencies to be consistent), the central carrier frequencies of the downlink BWP and the uplink BWP (uplink subband) may not be consistent in the above manner, and thus the handover delay between the uplink BWP and the downlink BWP may increase, resulting in poor data transmission performance of the UE.

Some concepts and/or terms related to a resource indication method, apparatus, device, system and storage medium provided in the embodiments of the present application are explained below.

The 5G mobile communication system needs to accommodate more diversified scenes and service demands than the conventional mobile communication system. The main 5G scenes include enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), low latency high reliability (Ultra Reliable Low Latency Communication, URLLC), mass internet of things communication or large-scale internet of things service (Massive Machine Type Communication, mctc), and the like, which put requirements on the system for high reliability, low latency, large bandwidth, wide coverage, and the like.

In NR, the network side configures BWP and/or carrier for data transmission for the UE. The bandwidth of the UE may change dynamically. As shown in fig. 2, at the first moment, the traffic of the UE is large, and the system configures a large bandwidth (i.e., BWP 1) for the UE; at the second moment, the traffic of the UE is smaller, and the system configures a small bandwidth (BWP 2) for the UE, so that the basic communication requirement is met; at the third moment, the system finds that there is a wide range of frequency selective fading in the bandwidth where BWP1 is located, or that the resources in the frequency range where BWP1 is located are relatively short, so that a new bandwidth (i.e., BWP 3) is configured for the UE.

The network-side device may instruct handover of the BWP through radio resource control (Radio Resource Control, RRC) or downlink control information (Downlink Control Information, DCI). The above example is that the network side device instructs the UE to perform BWP handover through RRC reconfiguration. In addition, the network side device may instruct the UE to perform BWP handover through DCI. When the network-side device configures the UE with a plurality of BWP, the network-side device may indicate one BWP ID through BWP indication information (bandwidth part indicator) in the DCI. The UE may determine whether a BWP handover is required by comparing whether the received BWP indication and the currently active BWP ID are identical.

Each BWP is not just different in frequency point and bandwidth, but each BWP may correspond to a different configuration. For example, the subcarrier spacing, cyclic Prefix (CP) type, synchronization signal block (Synchronization Signal Block, SSB) period, etc. of each BWP may be configured differently to accommodate different services.

The technical advantages of BWP are mainly four:

1. the UE does not need to support all bandwidths, only needs to meet the minimum bandwidth requirement, and is beneficial to the development of low-cost UE;

2. when the UE traffic is not large, the UE can be switched to low-bandwidth operation, so that the power consumption can be obviously reduced;

3. The 5G technology is forward compatible, when a new technology is added into the 5G technology, the new technology can be directly operated on a new BWP, so that the forward compatibility of the system is ensured;

4. and the BWP is dynamically configured for the service according to the service requirement.

Slot format: in LTE, the configuration of uplink and downlink is in units of time slots, that is, subframes; in NR, the uplink and downlink configuration takes the symbol as granularity, so that the configuration is more flexible. The specific configuration process is as follows:

(1) Firstly, semi-static uplink and downlink configuration of a configured cell

The higher layer provides a parameter TDD-UL-DL-configuration common (time division duplex uplink downlink common configuration), which includes a reference subcarrier spacing u (reference SCS configuration) and a pattern1 (pattern 1), and pattern1 includes: slot configuration period (slot configuration period), downlink slot number Dslots (number of slots with only downlink symbols), downlink symbol number Dsym (number of downlink symbols), uplink slot number Uslots (number of slots with only uplink symbols), uplink symbol number Usym (number of uplink symbols).

Where the configuration period p=0.625 ms is valid only for 120kHz subcarrier spacing, p=1.25 ms is valid only for 60 and 120kHz subcarrier spacing, and p=2.5 ms is valid only for 30 60 and 120kHz subcarrier spacing. Then a configuration period can be known by the formula s=p2u how many slots the period contains. Of these slots, the first Dslots slots are downlink slots, followed by Dsym downlink symbols, followed by Usym uplink symbols, and finally by Uslots uplink slots. After the uplink and downlink are configured in the S slots, the flexible symbol X remains.

If the parameters are given to pattern1 and pattern2 at the same time, two different slot formats can be consecutively configured, and the parameter form in pattern2 is similar to pattern 1.

(2) Then configuring the uplink and downlink configuration special for the cell

If, on the basis of the configuration in (1), a higher layer parameter TDD-UL-DL-ConfigDedicated (time division duplex uplink downlink dedicated configuration) is further provided, this parameter may configure a flexible symbol of the parameter TDD-UL-DL-configurationcom configuration. That is, the uplink and downlink symbols configured in (1) may not be changed, but the flexible symbols may be rewritten by TDD-UL-DL-configuration defined.

This parameter provides a series of slot configurations, for each slot configuration, a slot index (slot index) and a symbol configuration, for the slot specified by the slot index, which:

if symbols = all downlink (allddown), all symbols on the slot are downlink (all symbols in the slot are downlink);

if symbols = all uplinks (all uplink), all symbols are uplinks (all symbols in the slot are uplink) on the slot;

if symbols = explicit, then the parameter nrofDownlinkSymbols provides the number of downlink symbols, nrofUplinkSymbols provides the number of uplink symbols, the downlink symbol is forward most, the uplink symbol is rearmost, if the parameter nrofDownlinkSymbols is not provided, there are no downlink symbols, and if nrofUplinkSymbols is not provided. If there is a remainder after configuration, the remainder symbol is also the flexible symbol X. (2) The reference subcarrier spacing reference SCS configuration in (1) is the same.

(3) Dynamic DCI uplink and downlink configuration

The uplink and downlink configuration realized by the dynamic DCI is realized by DCI format 2-0 (namely DCI format 2-0), or is directly realized by the uplink and downlink data scheduling of DCI format 0-0, DCI format 0-1, DCI format 1-0 and DCI format 1-1. DCI format 2-0 is used exclusively as a slot format indication (Slot Format Indicator, SFI). The SFI may implement periodic frame structure configuration according to a single-slot supportable slot format, that is, from receiving DCI format 2-0, the physical downlink control channel (Physical Downlink Control Channel, PDCCH) continues for a period (monitoring period) of slots, which are all configured according to the indication of the SFI in this DCI. The maximum number of formats supported by a single slot is 256, and the number of formats already standardized is 56.

Typically, the base station (gNB) configures uplink and downlink transmission resources in frequency division on a continuous length of resources, such as downlink BWP (DL BWP) or uplink BWP (UL BWP). That is, on DL BWP, the gNB configures a part of the resources as uplink transmission resources (UL subbands), or on UL BWP, the gNB configures a part of the resources as downlink resources (UL subbands). In this way, the gNB may perform uplink reception or downlink transmission at the same time. The UE selects to transmit, i.e., either transmit or receive, on only a portion of the resources.

The resource indication method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

At present, different transmission directions are configured for different sub-bands of the frequency domain resource, so that at the same time, uplink transmission and downlink transmission are realized, and the uplink transmission and the downlink transmission are performed on the different sub-bands. Existing resource indication schemes indicate the transmission direction of both time and frequency domains of each sub-band after configuring non-overlapping sub-bands (subbands) on BWP. Since the configuration of the sub-bands may not meet the requirement of TDD UL/DL BWP pair center carrier frequencies, i.e., the center carrier frequencies of UL/DL BWP are identical, the center carrier frequencies of DL BWP and UL sub-bands may not be identical at this time, as shown in fig. 3. The switching delay of the UE between DL BWP and UL sub-bands may increase. If the center carrier frequencies of DL BWP and UL sub-bands are consistent, flexibility of UL sub-band configuration is reduced.

In this embodiment of the present application, the UE may receive configuration information from the network side device, where the configuration information is used to configure the UE with the first type BWP, including at least one first uplink BWP of the first type and/or at least one first downlink BWP of the first type, so that the UE may perform data transmission on the activated first type BWP according to the configuration information; and, each uplink BWP of the first type configured by the network side device is one uplink sub-band of the activated second type downlink BWP, and each first downlink BWP is one downlink sub-band of the activated second type uplink BWP, that is, the network side device configures a part of sub-bands different from the transmission direction of the activated second type uplink BWP as BWP corresponding to the transmission direction of the part of sub-bands, and/or configures a part of sub-bands different from the transmission direction of the activated second type downlink BWP as BWP corresponding to the transmission direction of the part of sub-bands, so that the configured sub-bands can be transmitted on the corresponding sub-bands by activating the first type BWP at the same time in case that the requirement of the TDD UL/DL BWP pair center carrier frequency is not satisfied. Thus, the scheme increases the flexibility of the first type BWP configuration, avoids the switching delay of the UE on different resources (namely the first type BWP and the second type BWP) transmission, and improves the data transmission performance of the UE.

The embodiment of the application provides a resource indication method, and fig. 4 shows a flowchart of the resource indication method provided by the embodiment of the application. As shown in fig. 4, the resource indication method provided in the embodiment of the present application may include the following steps 201 to 203.

Step 201, the network side device sends configuration information to the UE.

Step 202, the UE receives configuration information from a network side device.

In an embodiment of the present application, the configuration information is used to configure a first type BWP, where the first type BWP includes at least one of the following: at least one first upstream BWP and at least one first downstream BWP; the configuration information is used for data transmission by the UE on the activated first type BWP.

Wherein the first type BWP is one subband of the activated second type BWP, the second type BWP comprises a second type uplink BWP and/or a second type downlink BWP, each first uplink BWP is one uplink subband of the activated second type downlink BWP, and each first downlink BWP is one downlink subband of the activated second type uplink BWP.

In this embodiment of the present application, the bandwidth of each first uplink BWP is smaller than the bandwidth of the activated downlink BWP, and the bandwidth of each first downlink BWP is smaller than the bandwidth of the activated uplink BWP.

In this embodiment of the present application, each first uplink BWP may be one uplink subband in the second type downlink BWP, and each first downlink BWP may be one downlink subband in the second type uplink BWP. The second type of upstream BWP and the second type of downstream BWP may be configured legacy upstream BWP or downstream BWP, i.e. configured upstream BWP or downstream BWP in legacy protocols. When the second type of downlink BWP or the second type of uplink BWP is not activated, the corresponding first uplink BWP or first downlink BWP is not activated. Only when the second type of downlink BWP or the second type of uplink BWP is activated, the corresponding first uplink BWP or first downlink BWP may be activated. The effect is equivalent to one subband in the second type BWP where the first type BWP is active.

In this embodiment of the present application, the activated second type downlink BWP may include a plurality of uplink subbands, and the activated second type uplink BWP may include a plurality of downlink subbands.

It is understood that the at least one first upstream BWP is at least one first upstream BWP of the first type, and the at least one first downstream BWP is at least one first downstream BWP of the first type; the network side device configures at least one first uplink BWP and/or at least one first downlink BWP of the first type to the UE through the configuration information, so that the UE may perform data transmission based on the at least one first uplink BWP and/or the at least one first downlink BWP.

Alternatively, in the embodiment of the present application, the first type BWP may be a BWP in a Non-overlapping subband full duplex (Non-Overlapping Subband Full Duplex, SBFD) mode. The second type BWP may be BWP in a legacy (legacy) mode.

In this embodiment of the present application, the network side device may configure a subband (subband) different from the active uplink BWP transmission direction as a BWP corresponding to the subband transmission direction, and/or configure a subband different from the active downlink BWP transmission direction as a BWP corresponding to the subband transmission direction, that is, one downlink subband in the active uplink BWP is one SBFD downlink BWP (SBFD DL BWP), and/or one uplink subband in the active downlink BWP is one SBFD uplink BWP (SBFD UL BWP).

Alternatively, in the embodiment of the present application, the first type BWP may be configured by the network side device through dedicated RRC signaling, or may be configured by the network side device through RRC signaling for configuring the second type BWP.

Illustratively, as shown in fig. 5, the SBFD resources are configured as separate BWP. The SBFD uplink BWP (SBFD UL BWP) and SBFD downlink BWP (SBFD DL BWP) may be configured by RRC signaling configuring the second type BWP (the second type uplink BWP and the downlink BWP), where the IDs of the SBFD uplink BWP and the SBFD downlink BWP may be reserved for the second type uplink BWP and the downlink BWP starting with x, 0, 1, 2 … x-1. Where x may be equal to 4.

It should be noted that, the SBFD uplink BWP and the SBFD downlink BWP may be activated independently and separately, or the SBFD uplink BWP and the SBFD downlink BWP with identical IDs may be regarded as a pair, and both activation and deactivation may be implemented in pairs.

Step 203, the UE performs data transmission on the activated first type BWP according to the configuration information.

In this embodiment of the present application, the activated first type BWP includes an activated first type downlink BWP and/or an activated first type uplink BWP.

The embodiment of the application provides a resource indication method, wherein a UE can receive configuration information from a network side device, the configuration information is used for configuring a first type BWP to the UE, and the configuration information comprises at least one first uplink BWP of the first type and/or at least one first downlink BWP of the first type, so that the UE can perform data transmission on the activated first type BWP according to the configuration information; and, each uplink BWP of the first type configured by the network side device is one uplink sub-band of the activated second type downlink BWP, and each first downlink BWP is one downlink sub-band of the activated second type uplink BWP, that is, the network side device configures a part of sub-bands different from the transmission direction of the activated second type uplink BWP as BWP corresponding to the transmission direction of the part of sub-bands, and/or configures a part of sub-bands different from the transmission direction of the activated second type downlink BWP as BWP corresponding to the transmission direction of the part of sub-bands, so that the configured sub-bands can be transmitted on the corresponding sub-bands by activating the first type BWP at the same time in case that the requirement of the TDD UL/DL BWP pair center carrier frequency is not satisfied. Thus, the scheme increases the flexibility of the first type BWP configuration, avoids the switching delay of the UE on different resources (namely the first type BWP and the second type BWP) transmission, and improves the data transmission performance of the UE.

Optionally, in this embodiment of the present application, as shown in fig. 6 in conjunction with fig. 4, after step 202 described above, the resource indication method provided in this embodiment of the present application may further include step 301 and step 302 described below, and step 203 described above may be specifically implemented by step 203a described below.

Step 301, the network side device sends first indication information to the UE.

Step 302, the UE receives first indication information from a network side device.

In this embodiment of the present application, the first indication information is used to indicate or activate at least one of the following: a second upstream BWP and a second downstream BWP; the second upstream BWP is one or more of the at least one first upstream BWP, and the second downstream BWP is one or more of the at least one first downstream BWP.

Optionally, in the embodiment of the present application, the first indication information may be carried in DCI; the first indication information may be BWP indication information or first type BWP indication information.

Optionally, in the embodiment of the present application, the second uplink BWP and the second downlink BWP are independently indicated or activated by different DCIs by the network side device.

Optionally, in this embodiment of the present application, the first indication information is carried in DCI, the second uplink BWP is indicated or activated by a first indication field in the DCI of the uplink grant, and the second downlink BWP is indicated or activated by a second indication field in the DCI of the downlink grant; wherein the first indication domain is a BWP indication domain or a first type BWP indication domain, and the second indication domain is a BWP indication domain or a first type BWP indication domain.

It may be appreciated that the second uplink BWP is indicated or activated by BWP indication information in the uplink grant of the DCI, and the second downlink BWP is indicated or activated by BWP indication information in the downlink grant of the DCI. Or, the second uplink BWP is indicated or activated by the first type BWP indication information in the uplink grant of the DCI, and the second downlink BWP is indicated or activated by the first type BWP indication information in the downlink grant of the DCI.

Optionally, in the embodiment of the present application, the network side device may activate/indicate the second uplink BWP by using BWP indication information (BWP indicator) in the uplink grant (UL grant) such as dcio0_1 or dcio0_2.

Optionally, in the embodiment of the present application, the network side device may activate/indicate the second downlink BWP through the BWP indication information in the downlink grant such as dci1_1 or dci1_2.

Optionally, in the embodiment of the present application, the network side device may activate/indicate the second uplink BWP through the first type BWP indication information (SBFD BWP indicator indication field) in the uplink grant such as dcio0_1 or dcio0_2.

Optionally, in the embodiment of the present application, the network side device may activate/indicate the second downlink BWP through the first type BWP indication information in the downlink grant such as dci1_1 or dci1_2.

Optionally, in the embodiment of the present application, the second uplink BWP and the second downlink BWP are indicated or activated by the network side device through one DCI at the same time.

It is understood that the second upstream BWP and the second downstream BWP may be activated or indicated in pairs. The network side device activates or indicates the second uplink BWP and the second downlink BWP simultaneously by arbitrarily scheduling the BWP indication information or the first type BWP indication information in the DCI; wherein the ID of the activated or indicated second upstream BWP and the ID of the second downstream BWP coincide.

In step 203a, the UE performs data transmission on the activated first type BWP according to the configuration information and the first indication information.

In this embodiment, after receiving the DCI, if the second uplink BWP and/or the second downlink BWP indicated by the first indication information are in an inactive state, the UE may activate the second uplink BWP and/or the second downlink BWP to transmit data on the activated second uplink BWP and/or second downlink BWP. If the second uplink BWP and/or the second downlink BWP indicated by the first indication information are/is in the active state, the UE does not need to activate the second uplink BWP and/or the second downlink BWP, i.e., the UE may directly transmit data on the activated second uplink BWP and/or second downlink BWP.

Optionally, in the embodiment of the present application, after the step 202, the method for indicating a resource provided in the embodiment of the present application may further include a step 304 described below.

Step 304, the UE may activate the second uplink BWP and/or the second downlink BWP based on the default value indicated by the first indication information.

It should be noted that, the default value indicated by the first indication information refers to the second uplink BWP and/or the second downlink BWP.

Optionally, in the embodiment of the present application, the UE may activate at least one of the second uplink BWP and the second downlink BWP according to a default value indicated by the first indication information in the DCI; and/or deactivating at least one of the second upstream BWP and the second downstream BWP. Wherein the second upstream BWP and/or the second downstream BWP ID to be activated is indicated by a default value. The deactivated second upstream BWP and/or second downstream BWP is the currently activated second upstream BWP and/or second downstream BWP

Optionally, in the embodiment of the present application, the UE may activate all uplink BWP and/or all downlink BWP in the first type BWP or deactivate all uplink BWP and/or all downlink BWP in the first type BWP according to the default value indicated by the first indication information in the DCI.

It may be appreciated that after the UE activates the second uplink BWP and/or the second downlink BWP, data transmission may be performed on the activated second uplink BWP and/or second downlink BWP.

Optionally, in the embodiment of the present application, after the step 202, the method for indicating a resource provided in the embodiment of the present application may further include a step 305 described below.

Step 305, the UE periodically activates the first type BWP according to the configured period.

In the embodiment of the application, the UE activates BWP in the first type BWP and transmits data on the activated BWP.

It should be noted that, for the method of periodically activating the first type BWP by the UE, reference may be made to the description of the following embodiments, which are not repeated herein.

Optionally, in an embodiment of the present application, the BWP configured by the network side device includes a first type BWP and a second type BWP. The UE does not perform BWP handover between the second type BWP and the first type BWP when the UE transmits data on the activated first type BWP and/or the activated second type BWP.

It should be noted that, the handover herein can be understood as follows: activate new BWP and deactivate original BWP.

Optionally, in an embodiment of the present application, the second type BWP includes at least one of the following: at least one fourth upstream BWP and at least one fourth downstream BWP.

In this embodiment, when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE may simultaneously maintain two activated uplink BWP or two activated downlink BWP, i.e., the activated first type uplink/downlink BWP and the activated second type uplink/downlink BWP.

It may be appreciated that the BWP configured by the network-side device for the UE includes a first type BWP and a second type BWP, and when the UE transmits data on the activated BWP, if the UE transmits data on the activated second type BWP, the UE does not switch from the activated second type BWP to the second uplink BWP and/or the second downlink BWP when the network-side device indicates the second uplink BWP and/or the second downlink BWP through the first indication information, i.e., the UE keeps transmitting data on the activated second type BWP.

Optionally, in the embodiments of the present application, when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE performs BWP handover only between the second type BWP and/or the UE performs BWP handover only between the first type BWP.

Illustratively, it is assumed that the UE is configured with a plurality of BWP including a second type of downlink BWP (e.g., legacy DL BWP0, 1, 2), a second type of uplink BWP (e.g., legacy UL BWP0, 1, 2), a first type of downlink BWP (e.g., SBFD DL BWP4, 5), and a first type of uplink BWP (e.g., SBFD UL BWP4, 5). When the network side device activates or indicates BWP through DCI, at least one BWP of the plurality of BWP may be indicated according to different fields of BWP indication information in the DCI, and the currently activated BWP is shown in fig. 7, for convenience of illustration, it is assumed that the BWP activation delay is zero, that is, BWP may be immediately activated when the BWP indication is received, and there is a delay when the actual BWP is switched. In slots 0 (slot 0) and slot1, the indicated BWP ID is 0, and the currently activated BWP is legacy UL/DL BWP0; in slot2, the indicated BWP ID is 4, it may be determined that BWP is SBFD UL/DL BWP, and the UE does not switch between legacy BWP and SBFD BWP, so that SBFD UL/DL BWP4 is activated separately at this time, two BWPs are currently activated, one is legacy UL/DL BWP0 and one is SBFD UL/DL BWP 4. In slot3, the indicated BWP ID is 0, legacy UL/DL BWP0 is active BWP, and the UE does not perform any activation or deactivation operation. I.e. the UE switches from SBFD UL/DL BWP4 transmission to legacy UL/DL BWP0 transmission without any additional actual activation delay; at slot4, the indicated BWP ID is 1, then the UE deactivates legacy UL/DL BWP0 and activates legacy UL/DL BWP1; in slot5, the indicated BWP ID is 5, legacy UL/DL BWP1 of the UE remains active, the UE deactivates SBFD UL/DL BWP4, activates SBFD UL/DL BWP 5. Similarly, in slot6, the UE switches from SBFD UL/DL BWP5 transmission to legacy UL/DL BWP1 transmission, since the UE keeps both legacy UL/DL BWP1 and SBFD UL/DL BWP5 in active state, no additional actual activation delay is needed; at slot7, the indicated BWP is-1, which indicates that SBFD UL/DL BWP is deactivated, and only legacy UL/DL BWP1 is activated.

It should be noted that UL/DL BWP in the embodiment of the present application may represent one DL BWP alone, or one UL BWP alone, or one uplink-downlink BWP pair (i.e., UL BWP and DL BWP). Further, the above-described embodiment is logically identical when the ID of the first type BWP is indicated by the first type BWP indication field and the ID of the second type BWP is indicated by the BWP indication field.

In the embodiment of the application, by activating legacy UL/DL BWP and SBFD UL/DL BWP simultaneously, the flexibility of SBFD UL/DL BWP configuration can be increased, the switching delay of UE transmission on different resources can be reduced, and the system performance can be improved.

Optionally, in the embodiment of the present application, in a case where the UE performs BWP handover between the second type BWP, the UE deactivates (de-activate) the currently activated first type BWP.

Optionally, in the embodiment of the present application, in a case where the UE performs BWP handover between the second type BWP, the UE maintains the currently activated first type BWP.

Optionally, in the embodiment of the present application, in a case that the UE performs BWP handover between the second type BWP, the UE switches the currently activated first type BWP to the default first type BWP (default SBFD BWP).

Illustratively, in the above-described fig. 7, when switching from legacy UL/DL BWP0 to legacy UL/DL BWP1, the currently active SBFD UL/DL BWP is unchanged, i.e., within slot4, while legacy UL/DL BWP1 and SBFD UL/DL BWP4 are kept active. In addition, the UE may deactivate SBFD UL/DL BWP4 at the same time as the legacy UL/DL BWP0, the currently activated BWP becomes legacy UL/DL BWP1, or the UE may switch SBFD UL/DL BWP to default SBFD BWP (default SBFD UL/DL BWP) as shown in fig. 8.

Optionally, in the embodiment of the present application, when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE performs BWP handover only between the first type BWP.

Optionally, in the embodiment of the present application, in a case that the UE performs BWP handover between the first type BWP, the UE deactivates the currently activated BWP.

Optionally, in the embodiment of the present application, in a case where the UE performs BWP handover between the first type BWP, the UE maintains the current activated BWP.

Optionally, in the embodiment of the present application, in a case that the UE performs BWP handover between the first type BWP, the UE switches the current activated BWP to the default BWP (default BWP).

Illustratively, in fig. 7 described above, when switching from SBFD UL/DL BWP4 to SBFD UL/DL BWP5, the currently active legacy UL/DL BWP is unchanged, i.e., within slot5, while legacy UL/DL BWP1 and SBFD UL/DL BWP5 are kept active. In addition, the UE may deactivate legacy UL/DL BWP1 at the same time as the SBFD UL/DL BWP4, the currently activated BWP becomes SBFD UL/DL BWP5, or the UE may switch legacy UL/DL BWP to default BWP (default UL/DL BWP) as shown in fig. 9.

Optionally, in an embodiment of the present application, scheme one: the UE does not perform BWP handover between the second type BWP and the first type BWP when the UE transmits data on the activated first type BWP and/or the activated second type BWP. Scheme II: when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE performs BWP handover only between the second type BWP; and/or, when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE performs BWP handover only between the first type BWP. The first scheme and the second scheme may be used in combination.

Optionally, in the embodiment of the present application, the UE may activate or deactivate BWP in the first type BWP according to the indication of the DCI; alternatively, the UE or the network-side device may deactivate BWP in the first type BWP based on the timer; or the UE or the network-side device may periodically activate/deactivate BWP in the first type BWP. The activation/deactivation scheme of the UE or the network side device is described below through specific embodiments.

Optionally, in the embodiment of the present application, after the step 202, the method for indicating a resource provided in the embodiment of the present application may further include a step 306 described below.

Step 306, the UE deactivates the third uplink BWP and/or the third downlink BWP.

In this embodiment of the present application, the third uplink BWP is one or more of the at least one first uplink BWP, and the third downlink BWP is one or more of the at least one first downlink BWP.

Alternatively, in the embodiment of the present application, the above step 306 may be specifically implemented by the following step 401, step 402, or step 403.

Step 401, the UE deactivates the third uplink BWP and/or the third downlink BWP based on the invalid value indicated by the DCI.

Step 402, the UE deactivates the third uplink BWP and/or the third downlink BWP when the first timer expires.

In this embodiment of the present application, the first timer is started after the first type BWP is activated.

In this embodiment, after the UE activates the BWP in the first type BWP, the UE starts to count by the timer of the UE (i.e., the first timer), and deactivates the currently activated first type BWP if the timer of the UE expires.

In the embodiment of the application, the UE deactivates the SBFD UL/DL BWP by a timer. The timer starts counting after the activation of the SBFD UL/DL BWP, and when the timer expires (e.g., is greater than or equal to a preset time or the timer is reduced to zero), the UE may deactivate the currently activated SBFD UL/DL BWP.

Alternatively, in the embodiment of the present application, the first type of uplink BWP (SBFD UL BWP) and the first type of downlink BWP (SBFD DL BWP) may have separate timers; alternatively, the first type of upstream BWP and the first type of downstream BWP may have the same timer.

Step 403, the UE periodically deactivates the third uplink BWP and/or the third downlink BWP.

In the embodiment of the application, the UE may periodically activate or deactivate BWP in the first type BWP and transmit data on the activated BWP.

Optionally, in the embodiment of the present application, the network side device may configure ON/OFF (ON/OFF) of SBFD UL/DL BWP; the corresponding BWP is activated under the turn-on of the SBFD UL/DL BWP or deactivated under the turn-off of the SBFD UL/DL BWP.

Optionally, in the embodiment of the present application, the network side device may configure an SBFD UL/DL BWP activation/deactivation period; the corresponding BWP is activated during an activation period of the SBFD UL/DL BWP or deactivated during a deactivation period of the SBFD UL/DL BWP.

It can be appreciated that the network side device configures ON/OFF or activation/deactivation periods for the SBFD UL BWP of the UE, and configures ON/OFF or activation/deactivation periods for the SBFD DL BWP of the UE, respectively. When the periods configured for the SBFD UL BWP and the SBFD DL BWP coincide, the SBFD UL BWP and the SBFD DL BWP may be activated/deactivated simultaneously; when the periods configured for the SBFD UL BWP and the SBFD DL BWP do not coincide, activation/deactivation may be performed according to the respective periods of the SBFD UL BWP and the SBFD DL BWP.

Optionally, in the embodiment of the present application, after the step 202, the method for indicating a resource provided in the embodiment of the present application may further include the following steps 501 and 502.

Step 501, the network side device activates BWP in the first type BWP.

Step 502, the network side device deactivates the currently activated first type BWP when the second timer expires.

In this embodiment of the present application, the second timer is started after the network side device activates BWP in the first type BWP.

In this embodiment of the present application, after the network side device activates the BWP in the first type BWP, the timer of the network side device starts to count, and in the case that the timer (i.e., the second timer) of the network side device times out, the current activated first type BWP is deactivated.

Optionally, in the embodiment of the present application, after the step 202, the method for indicating a resource provided in the embodiment of the present application may further include a step 601 described below.

Step 601, the network side device periodically activates or deactivates BWP in the first type BWP.

It should be noted that, for the method of activating or deactivating the BWP in the first type BWP by the network side device, reference may be made to the related method on the UE side, which is not described herein.

According to the resource indication method provided by the embodiment of the application, the execution main body can also be a resource indication device. In the embodiment of the present application, a resource indication method provided by the embodiment of the present application is described by taking an example of a method for interactively executing resource indication between a UE and a network side device.

Fig. 10 shows a schematic diagram of a possible structure of a resource indicating device according to an embodiment of the present application, where the resource indicating device is applied to a UE. As shown in fig. 10, the resource indicating device 70 may include: a receiving module 71 and a transmitting module 72.

Wherein, the receiving module 71 is configured to receive configuration information from the network side device, where the configuration information is used to configure a first type BWP, and the first type BWP includes at least one of the following: at least one first upstream BWP and at least one first downstream BWP. A transmission module 72, configured to perform data transmission on the activated first type BWP according to the configuration information received by the receiving module 71; wherein the first type BWP is one subband of the activated second type BWP, the second type BWP comprises a second type uplink BWP and/or a second type downlink BWP, each first uplink BWP is one uplink subband of the activated second type downlink BWP, and each first downlink BWP is one downlink subband of the activated second type uplink BWP.

Thus, the scheme increases the flexibility of the first type BWP configuration, avoids the switching delay of the UE on different resources (namely the first type BWP and the second type BWP) transmission, and improves the data transmission performance of the UE.

In a possible implementation manner, the receiving module 71 is further configured to receive, after receiving the configuration information from the network side device, first indication information from the network side device, where the first indication information is used to indicate or activate at least one of the following: a second upstream BWP and a second downstream BWP; the second upstream BWP is one or more of the at least one first upstream BWP, and the second downstream BWP is one or more of the at least one first downstream BWP.

And a deactivation module for deactivating a third upstream BWP and/or a third downstream BWP, wherein the third upstream BWP is one or more of the at least one first upstream BWP, and the third downstream BWP is one or more of the at least one first downstream BWP.

In a possible implementation manner, the deactivating module is specifically configured to deactivate the third uplink BWP and/or the third downlink BWP based on the invalid value indicated by the DCI; alternatively, the third upstream BWP and/or the third downstream BWP is deactivated when the first timer expires, the first timer being started after the first type BWP is activated; alternatively, the third upstream BWP and/or the third downstream BWP are periodically deactivated.

In one possible implementation, the network-side device configured BWP comprises a first type BWP and a second type BWP. The UE does not perform BWP handover between the second type BWP and the first type BWP when the UE transmits data on the activated first type BWP and/or the activated second type BWP.

In one possible implementation, the UE performs BWP handover only between the second type BWP when the UE transmits data on the activated first type BWP and/or the activated second type BWP; and/or, when the UE transmits data on the activated first type BWP and/or the activated second type BWP, the UE performs BWP handover only between the first type BWP.

In one possible implementation, in case the UE performs a BWP handover between the second type BWP, the UE deactivates the currently activated first type BWP; alternatively, in case the UE performs BWP handover between the second type BWP, the UE maintains the currently activated first type BWP; alternatively, in case the UE performs BWP handover between the second type BWP, the UE hands over the currently activated first type BWP to the default first type BWP.

In one possible implementation, in case the UE performs a BWP handover between the first type BWP, the UE deactivates the currently activated BWP; alternatively, in case the UE performs BWP handover between the first type BWP, the UE maintains the currently activated BWP; alternatively, in case the UE performs BWP handover between the first type BWP, the UE hands over the currently activated BWP to the default BWP.
