[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311649787.X filed on November 30, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a resource activation method, apparatus, terminal, and network-side equipment. Background Art

[0004] Current communications technologies only support one active bandwidth part (BWP). However, with technological advancements, it's become possible to refarm existing spectrum to obtain more frequency domain resources. However, the available spectrum in low-frequency bands with better channel quality is fragmented, with each segment having a very small bandwidth, such as 3 MHz, 4 MHz, or 7 MHz. One implementation approach is to configure the fragmented spectrum into different BWPs. To efficiently utilize resources, multiple BWPs may need to be activated simultaneously for data transmission. Furthermore, for activated BWPs, data is not always scheduled on all of them. For example, if BWP1, BWP2, and BWP3 are activated, data scheduled in slot 1 is on BWP1 and BWP2, while data scheduled in slot 2 is on BWP2 and BWP3. Unscheduled BWPs are not deactivated, resulting in wasted resources.

[0056] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0057] 1. Band Width Part (BWP)

[0058] In New Radio (NR), the network configures one or more bandwidths (BWPs) for user equipment (UE) for data transmission. A BWP is a continuous range of resources in the frequency domain. The UE dynamically changes bandwidth by activating different BWPs, as shown in Figure 2. At the first moment, the UE's traffic volume is high, so the UE activates a large bandwidth (BWP1). At the second moment, the UE's traffic volume is low, so the UE activates a small bandwidth (BWP2) that only meets basic communication needs. At the third moment, the system detects large-scale frequency selective fading within the bandwidth of BWP1, or that resources are relatively scarce within the frequency range of BWP2, so it instructs the UE to activate a new bandwidth (BWP3).

[0059] Each BWP may correspond to different configuration parameters, including subcarrier spacing, BWP location and bandwidth, and cyclic prefix (CP).

[0060] 2. Activation and deactivation of BWP

[0061] NR UE only supports one active BWP, and the activation methods include activation based on scheduling downlink control information (DCI), activation based on radio resource control (RRC) reconfiguration, and activation based on a timer. Scheduling DCI, such as DCI 0-1, DC 0-2, DCI 1-1, DCI 1-2, etc., contains a bandwidth part indicator field, which indicates the ID of the BWP where the resources scheduled by the DCI are located. When the ID indicated by the bandwidth part indicator is the same as the ID of the currently activated BWP, it means scheduling on the current BWP. When the ID indicated by the bandwidth part indicator is different from the ID of the currently activated BWP, the UE switches to the indicated target BWP, that is, deactivates the current BWP and activates the target BWP.

[0062] When the base station configures only one BWP for the UE, the BWP is assumed to be the active BWP. When the base station reconfigures the BWP for the UE, the currently active BWP is deactivated and the newly configured BWP is activated.

[0063] In addition, the BWP can also be deactivated by a timer. When the UE activates a BWP, the BWP deactivation timer (bwp-InactivityTimer) starts timing. Whenever the UE receives a DCI scheduling the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) or physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), the UE resets the bwp-InactivityTimer. When the bwp-InactivityTimer times out, the UE switches to the default BWP (default BWP configured) or the initial BWP (no default BWP configured).

[0064] In this application, BWP only represents a part of continuous or discrete resources in the frequency domain, which can be a resource block set (RB set), subband, carrier, bandwidth, BWP, etc.

[0065] In this application, instructing activation or deactivation can also be understood as instructing the terminal to perform activation or deactivation operations.

[0066] In the present application, the indicated activated BWP may also be understood as a BWP to be activated, that is, the BWP has not been activated yet.

[0067] In this application, the BWP indication mark can also be understood as indicating BWP.

[0068] The resource activation method, apparatus, terminal, and network-side equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0069] As shown in FIG3 , a resource activation method according to an embodiment of the present application includes:

[0070] Step 301: The terminal activates or deactivates the bandwidth part BWP by at least one of the following methods:

[0071] receiving a first signaling, where the first signaling is used to instruct activation of the first BWP or deactivation of the second BWP;

[0072] receiving a second signaling or a third signaling, wherein the second signaling is used to instruct activation of a third BWP, and the third signaling is used to instruct deactivation of a fourth BWP;

[0073] Receive configuration information or indication information of an activation or deactivation period of a fifth BWP.

[0074] In this way, when the terminal receives the first signaling indicating the activation of the first BWP or the deactivation of the second BWP, or the second signaling indicating the activation of the third BWP or the third signaling indicating the deactivation of the fourth BWP, or at least one of the configuration information or indication information of the activation or deactivation period of the fifth BWP, it can activate or deactivate the corresponding BWP based on the scheduling situation, so that the terminal can utilize resources more flexibly and efficiently.

[0075] It should be noted that, before step 301, the terminal will receive target signaling (first signaling, or second signaling or third signaling) sent by the network side device, or configuration information or indication information of the activation or deactivation cycle of a specific BWP.

[0076] Optionally, in this embodiment, the first signaling is used to indicate activation of the first BWP or deactivation of the second BWP. It can be understood that, for BWP, the first signaling can be used to indicate both activation and deactivation. For example, the first signaling can only indicate activation of BWP, or only indicate deactivation of BWP, or indicate activation of BWP and deactivation of BWP.

[0077] Optionally, in this embodiment, the first signaling includes first information and second information, the first information includes activation or deactivation indication information, and the second information includes information for indicating an identifier of the first BWP or the second BWP.

[0078] That is, the first signaling informs the terminal which BWPs need to be activated or which BWPs need to be deactivated through the first information and the second information.

[0079] The first information and the second information can also be understood as fields carrying corresponding information in the first signaling. The first signaling indicates activation or deactivation and a BWP identifier through at least one field.

[0080] Optionally, the first information indicates deactivation or maintaining activation of a sixth BWP, where the sixth BWP is the BWP that transmits the first signaling; the identifier of the BWP indicated by the second information is the identifier of the first BWP; or,

[0081] The first information indicates activation of the first BWP or deactivation of the second BWP; the identifier of the BWP indicated by the second information is the identifier of the first BWP or the identifier of the second BWP; or

[0082] The first information indicates whether to deactivate the seventh BWP, or to activate the first BWP, the seventh BWP is a BWP other than the first BWP among the activated BWPs, and the first BWP is a default BWP or an initial BWP; the identifier of the BWP indicated by the second information is the identifier of the first BWP.

[0083] Therefore, the terminal obtains the first information and the second information. When the first information indicates to deactivate or maintain activation of the sixth BWP and the identifier of the BWP indicated by the second information is the identifier of the first BWP, the terminal can know from the first information whether to deactivate the BWP that transmits the first signaling, and know from the second information which first BWPs are activated; when the first information indicates to activate the first BWP or deactivate the second BWP and the identifier of the BWP indicated by the second information is the identifier of the first BWP or the identifier of the second BWP, the terminal can know from the first information whether the identifier of the BWP indicated by the second information is to deactivate the BWP or activate the BWP, and then know from the second information which BWPs are activated or deactivated; when the first information indicates whether to deactivate the seventh BWP or activate the first BWP and the identifier of the BWP indicated by the second information is the identifier of the first BWP, the terminal can know from the first information whether to deactivate the other BWPs in the activated BWPs (all activated BWPs) except the default BWP or the initial BWP, or to activate the default BWP (default BWP) or the initial BWP.

[0084] The first information indicating activation of the default BWP is applicable to the case where the default BWP has not been activated before, and the first information indicating activation of the initial BWP is applicable to the case where no default BWP is configured. Of course, when the first information indicates whether to deactivate the seventh BWP or activate the first BWP, the terminal may ignore the second information.

[0085] Optionally, in this embodiment, the first information is indicated by a specific value of a first information field of the first signaling, or is indicated by a dedicated information field of the first signaling.

[0086] On the one hand, for the first information field of the first signaling (such as the Frequency Domain Resource Allocation (FDRA) field, the Time Domain Resource Allocation (TDRA) field, etc.), activation or deactivation is indicated by setting a specific value. For example, all 0s in the FDRA field indicate activation, and all 1s in the FDRA field indicate deactivation; or, the FDRA field is set to a valid value to indicate activation, and all 0s or all 1s indicate deactivation. For example, k0, k2 or the Start and Length Indicator Value (SLIV) in TDRA, valid values ​​or invalid values ​​or special values ​​indicate activation and deactivation: such as valid SLIV or special SLIV values ​​indicate activation, invalid SLIV or special SLIV values, k0 or k2 values ​​of infinity indicate deactivation, etc.

[0087] On the other hand, a new field is added to the first signaling as a dedicated information field to indicate activation or deactivation, such as adding a new field to indicate activation or deactivation through 1 bit: 0 indicates activation, and 1 indicates deactivation.

[0088] Optionally, if simultaneous activation or deactivation of multiple BWPs is supported, the first signaling may include multiple first information fields, and each first information field indicates activation or deactivation of a corresponding BWP.

[0089] Optionally, in this embodiment, the second information is indicated by the first bandwidth part indication field of the first signaling, or indicated by the first bitmap of the first signaling, or indicated by the adjustment and coding strategy indication field of the first signaling.

[0090] In this way, assuming that the second information is indicated by the first bandwidth part indicator field, the first information field of the first signaling can indicate whether the BWP transmitting the first signaling is deactivated by setting a specific value or adding a new field to the first signaling through 1 bit; it can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; it can indicate whether to deactivate all BWPs except the default BWP or the initial BWP among all activated BWPs, or activate the default BWP or the initial BWP.

[0091] Assuming that the second information passes through the first bitmap, the first information field of the first signaling is set to a specific value or the first signaling adds a new field through 1 bit, which can indicate whether the BWP transmitting the first signaling is deactivated; it can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; it can indicate whether to deactivate all BWPs except the default BWP or the initial BWP in all activated BWPs, or activate the default BWP or the initial BWP.

[0092] Assuming that the second information is indicated by the Modulation and Coding Scheme (MCS) indication field, the first information field of the first signaling can indicate whether the BWP transmitting the first signaling is deactivated by setting a specific value or adding a new field to the first signaling through 1 bit; it can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; it can indicate whether to deactivate all activated BWPs except the default BWP or the initial BWP, or activate the default BWP or the initial BWP.

[0093] Optionally, each bit in the first bitmap indicates whether the corresponding BWP is valid in an activation or deactivation operation.

[0094] Each bit in the first bitmap is associated with a BWP identifier. Thus, the value of the bit indicates whether the BWP corresponding to the bit (with the identifier associated with the bit) is valid for activation or deactivation. Assuming that 1 indicates valid and 0 indicates invalid, when the first information indicates activation of the first BWP and the first bitmap is 0001, the BWP corresponding to the fourth bit is valid for activation. In other words, the terminal learns that the first BWP is the BWP with the identifier associated with the fourth bit in the first bitmap.

[0095] Optionally, in this embodiment, the first information and the second information are carried in padding bits of the first signaling.

[0096] The first signaling indicates the first information and the second information through padding bits.

[0097] Optionally, in this embodiment, the first signaling includes third information and fourth information, the third information includes information for indicating an identifier of the first BWP, and the fourth information includes information for indicating an identifier of the second BWP.

[0098] That is, at this time, the first signaling may indicate the flag for activating the BWP and the flag for deactivating the BWP.

[0099] The third information and the fourth information can be understood as fields carrying corresponding information in the first signaling. The first signaling indicates the flag for activating the BWP and the flag for deactivating the BWP respectively through at least one field.

[0100] Optionally, the third information and the fourth information are carried in padding bits of the first signaling; or,

[0101] The third information and the fourth information are respectively indicated by two first bandwidth part indication fields of the first signaling, or are respectively indicated by two first bitmaps of the first signaling.

[0102] On the one hand, the first signaling indicates the third information and the fourth information through padding bits. On the other hand, the two first bandwidth part indication fields in the first signaling respectively indicate the third information and the fourth information, or the two first bit maps respectively indicate the third information and the fourth information.

[0103] Wherein, for the first bandwidth part indication field or the first bitmap indicating the deactivation of the BWP flag, when no BWP needs to be deactivated, an invalid value or a reserved value or any one or more inactivated BWPs may be indicated.

[0104] Optionally, in this embodiment, the first signaling includes a second bandwidth part indication field or a second bitmap, and the second bandwidth part indication field or the second bitmap includes: a bit for indicating the identifier of the first BWP or the second BWP, and a bit for indicating an activation indication or a deactivation indication.

[0105] The second bandwidth part indication field can be understood as an enhancement of the first bandwidth part indication field, and the first bitmap can also be understood as an enhancement of the first bitmap, with an additional bit for indicating an activation indication or a deactivation indication, such as adding one bit. Specifically, the specific implementation of the second bandwidth part indication field or the second bitmap indication is similar to the implementation of the first signaling adding a new field to indicate the first information through one bit, and indicating the second information through the first bandwidth part indication field or the first bitmap, and will not be repeated here.

[0106] Optionally, in this embodiment, the padding bits are idle bits in the first signaling except for bits carrying relevant information of scheduling BWP.

[0107] That is, in the first signaling, the idle bits other than the bits carrying the related information of the scheduled BWP will carry the first information and the second information, or carry the third information and the fourth information.

[0108] Scheduling a BWP may also be understood as scheduling a terminal to receive or transmit on a corresponding BWP. Information related to scheduling a BWP includes, but is not limited to, an identifier of the scheduled BWP, time domain resources, and frequency domain resources.

[0109] The size of the first signaling may be determined by the maximum number of BWPs allowed to be activated simultaneously (the maximum number of BWPs that can be activated). Furthermore, the padding bits carry the first information and the second information, or carry the third information and the fourth information, and are applicable to a case where the number of scheduled BWPs is less than the maximum number of BWPs that can be activated.

[0110] Optionally, in this embodiment, the first signaling is DCI, wherein the first signaling may be scheduling DCI; or the first signaling is first-stage DCI (1st stage DCI), and second-stage DCI (2nd stage DCI) is used to schedule BWP.

[0111] When the scheduling DCI is used to activate, the scheduled BWP is the activated BWP. When the scheduling DCI is used to deactivate the BWP, the scheduling resource (eg, TDRA, FDRA, etc.) indication may be ignored.

[0112] Optionally, in this embodiment, the second signaling includes information for indicating an identifier of the third BWP; the third signaling includes information for indicating an identifier of the fourth BWP, or the third signaling is configuration information of a timer.

[0113] The second signaling is dedicated to instructing activation, and the third signaling is dedicated to instructing deactivation. That is, the network-side device can instruct the terminal to activate and deactivate the BWP through at least two signalings.

[0114] The configuration information of the timer (bwp-InactivityTimer) can be configured for each BWP, including the timer duration, the corresponding BWP identifier, etc. When a BWP is activated, the timer corresponding to the BWP starts counting, and the BWP is deactivated after the timer expires. In addition, the timer is reset every time the UE receives a DCI scheduling PDSCH or PUSCH.

[0115] The second signaling and the third signaling may indicate the BWP identifier through a bandwidth part indicator or a bitmap.

[0116] Optionally, the second signaling is a scheduling DCI, and the third signaling is a non-scheduling DCI; or,

[0117] The second signaling is a first-level DCI, and the third signaling is a second-level DCI; or,

[0118] The second signaling or the third signaling is one of radio resource control RRC, DCI and medium access control-control element (MAC CE).

[0119] Of course, the signaling formats of the second signaling and the third signaling are not limited to the above contents, and other signaling formats can also be used, which are not listed here one by one.

[0120] Optionally, the terminal receiving the second signaling or the third signaling includes:

[0121] The terminal receives a scheduling DCI or a non-scheduling DCI, wherein the scheduling DCI is used to activate the BWP and the non-scheduling DCI is used to deactivate the BWP; or

[0122] The terminal receives a first-level DCI or a second-level DCI, where the first-level DCI is used to activate the BWP and the second-level DCI is used to deactivate the BWP; or

[0123] The terminal receives one of a radio resource control RRC, a DCI and a media access control-control element MAC CE, or configuration information of a timer, wherein the RRC, the DCI or the MAC CE is used to activate the BWP, and the timer is used to deactivate the BWP.

[0124] In this way, in one way, the network-side device activates the BWP through a scheduling DCI instruction and deactivates the BWP through a non-scheduling DCI (such as a group-common DCI); in another way, the network-side device activates the BWP through a 1st stage DCI instruction and deactivates the BWP through a 2nd stage DCI, where the 1st stage DCI can also be used to schedule the BWP; in another way, the network-side device activates the BWP through an RRC, DCI, or MAC CE instruction and deactivates the BWP through a timer configuration information instruction. Of course, for the network-side device to activate the BWP through RRC, DCI, or MAC CE, it can also activate the BWP through RRC or MAC CE instructions, for example, RRC is the second signaling and MAC CE is the third signaling.

[0125] Optionally, in this embodiment, the terminal deactivating the BWP includes:

[0126] In a case where there is only one activated BWP and the activated BWP is not a default BWP or an initial BWP, deactivating the activated BWP and activating the default BWP or the initial BWP at the same time;

[0127] In a case where there is only one activated BWP, and the activated BWP is the default BWP or the initial BWP, the activated BWP remains activated.

[0128] When there is only one activated BWP, the terminal can activate or deactivate the corresponding BWP according to whether the activated BWP is the default BWP or the initial BWP.

[0129] Optionally, in this embodiment, the terminal deactivating the BWP by receiving the configuration information of the timer includes:

[0130] In a case where the eighth BWP is not a default BWP or an initial BWP, deactivating the eighth BWP and activating the default BWP or the initial BWP at the same time;

[0131] In a case where the eighth BWP is a default BWP or an initial BWP, keeping the eighth BWP activated;

[0132] The eighth BWP is the BWP that needs to be deactivated corresponding to the timer and is the only activated BWP before the timer times out.

[0133] A timer (bwp-InactivityTimer) times out at the current moment, that is, the BWP corresponding to the timer needs to be deactivated. If the BWP is the only activated BWP at the current moment, then the BWP is the eighth BWP. The terminal will activate or deactivate the BWP based on whether it is the default BWP or the initial BWP. If the eighth BWP is not the default BWP or the initial BWP, the default BWP or the initial BWP will be activated while the eighth BWP is deactivated; if the eighth BWP is the default BWP or the initial BWP, the eighth BWP will remain activated and the timer of the BWP will be ignored.

[0134] If a default BWP is configured, when the eighth BWP is not the default BWP, the eighth BWP is deactivated and the default BWP is activated. If a default BWP is not configured, when the eighth BWP is not the initial BWP, the initial BWP is deactivated and the eighth BWP is activated.

[0135] Optionally, in this embodiment, the BWP identifier includes at least one of the following: a BWP identity (ID) and a BWP group index. The BWP group index can also be understood as a BWP set index, such as when the second information includes an index of a BWP group or set. Therefore, if the network-side device configures a BWP combination (e.g., {BWP0, BWP3}, {BWP1, BWP2, BWP3}, etc.) via RRC, each combination corresponds to an index; upon receiving the index, the terminal activates or deactivates all BWPs in the combination corresponding to the index.

[0136] Optionally, the configuration information or indication information includes information for indicating at least one of the following:

[0137] the starting position of the activation or deactivation cycle;

[0138] an offset of the starting position of the activation or deactivation cycle;

[0139] activation time within the activation or deactivation cycle;

[0140] a deactivation time within the activation or deactivation cycle;

[0141] The length of the activation or deactivation period.

[0142] A corresponding activation and deactivation period is set for each BWP (which can also be understood as each BWP combination), so that the UE activates or deactivates the BWP within the corresponding period.

[0143] The starting position of the activation or deactivation period can be a specific radio frame, or it needs to be determined by an offset relative to the radio frame, such as the starting position of the activation and deactivation period of the BWP or BWP combination is the position that is offset from the starting or ending position of the even radio frame, or the position that is offset from the starting or ending position of the odd radio frame.

[0144] Optionally, in this embodiment, the terminal activates or deactivates the BWP by receiving the configuration information or the instruction information, including:

[0145] The terminal activates a fifth BWP at an activation time within the activation or deactivation period, and deactivates the fifth BWP at a deactivation time within the activation or deactivation period, where the fifth BWP is a BWP corresponding to the activation or deactivation period.

[0146] Here, the activation-deactivation cycle may include two parts: activation time and deactivation time. For example, for a certain BWP or BWP combination, its activation-deactivation cycle P = activation time Pa + deactivation time Pd. The UE uses P as a period, activates the BWP or BWP combination within the Pa time, and then deactivates the BWP or BWP combination within the Pd time. If a certain moment belongs to Pa of at least two BWPs or BWP combinations, then at this time there will be at least two BWPs or BWP combinations activated. In addition, the starting position of the activation-deactivation cycle of the BWP or BWP combination can also be configured. The starting position can be defined by the offset with the radio frame. For example, the starting position of the activation-deactivation cycle of the BWP or BWP combination is an offset from the start / end position of the even / odd radio frame.

[0147] In this embodiment, the first BWP, the second BWP, the third BWP, the fourth BWP, the fifth BWP, etc., unless otherwise specified, can be one or more BWPs, BWP groups, or BWP sets.

[0148] It should be noted that, in this embodiment, the above deactivation process can also be used to instruct the terminal to switch to a dormant BWP.

[0149] The following describes the application of the embodiments of the present application in conjunction with specific scenarios:

[0150] Scenario 1:

[0151] Assume that the base station has configured four BWPs for UE1, namely BWP0--BWP3, where BWP0 is the initial BWP and BWP3 is the default BWP. The base station instructs the UE to activate or deactivate the corresponding BWP through two fields in the DCI (first signaling) (one field indicates the first information and the other field indicates the second information).

[0152] For example, when FDRA is set to all 0s, or FRDA is set to a valid value, or the newly added field (called the activation / deactivation field) takes a value of 0, at this time, the first information indicates to keep the BWP for transmitting the first signaling activated, and the base station sends the above indication on the initial BWP0; and the first bandwidth part indicator field (bandwidth part indicator) indicates 2 (indicating activation of BWP2), or the first bitmap is set to 0010 (indicating that the activation operation is effective for BWP2), then the UE activates BWP2 and keeps BWP0 activated.

[0153] Afterwards, when FDRA is set to all 1s, or FDRA is set to an invalid value (either all 0s or all 1s), or the newly added activation / deactivation field value is 1, the base station sends the above indication on BWP0, and the bandwidth part indicator is 2, or the bitmap is set to 0010, the UE can perform one of the following operations:

[0154] 1. Deactivate BWP0 and keep BWP2 activated (the first information indicates deactivation of the BWP that transmits the first signaling, and the identifier of the BWP indicated by the second information is the identifier of the activated BWP);

[0155] 2. Deactivate BWP2 and keep BWP0 activated (the first information indicates activation of the initial BWP, and the second information indicates the BWP identifier for deactivating the BWP);

[0156] 3. Deactivate BWP0 and BWP2, and activate BWP3 (the first information indicates deactivation of the activated BWPs except the default BWP, and the second information indicates activation of the default BWP).

[0157] Scenario 2:

[0158] When the first information field (FDRA field) is used to indicate the first information (activation, deactivation of BWP), and the first bitmap is used to indicate BWP, if the simultaneous activation or deactivation of multiple BWPs is supported, that is, one DCI can schedule or indicate multiple BWPs, then the value of each FDRA field indicates the activation or deactivation of the corresponding BWP. Assuming that the BWP is configured as in scenario 1, the UE transmits on BWP0 after initial access. Assuming that the UE can activate up to 3 BWPs at the same time, the FDRA field in the DCI includes FDRA1, FDRA2, and FDRA3, which correspond to the frequency domain resource indications of each activated BWP. When the values ​​of FDRA1-FDRA3 are all 0 or all 1, and valid values ​​or all 0 / all 1, the corresponding three BWPs are activated or deactivated. For example, the valid value of FDRA is used to indicate activation, and the invalid value is used to indicate deactivation. If FDRA1 is a valid value, FDRA2 is a valid value, FDRA3 is all 0 / all 1, and the first bitmap is set to 1010, then the UE keeps BWP0 activated and newly activates BWP2. Afterwards, if FDRA1 in the newly received DCI is all 0 / all 1, FDRA2 is all 0 / all 1, FDRA3 is a valid value, and the first bitmap is set to 1011, then the UE deactivates BWP0 and BWP2 and activates BWP3. FDRA set to a valid value indicates frequency domain resource scheduling on the corresponding BWP.

[0159] Similarly, assuming that each BWP corresponds to its own TDRA domain, TDRA can be used to activate or deactivate the BWP. Only activation and deactivation indications are given here as examples, and the BWP indications are not repeated. Since there are invalid values / invalid combinations in SLIV, special values / combinations among these invalid values / invalid combinations can be used to indicate activation or deactivation of the BWP. For example, SLIV value / combination 1 indicates activation, and value / combination 2 indicates deactivation. Activation and deactivation can also be indicated by special values ​​of k0 or k2. For example, when k0 takes an infinite value, it indicates activation, and when k2 takes an infinite value, it indicates deactivation. Or when both values ​​are infinite, it indicates deactivation. Furthermore, all valid values ​​of TDRA can also indicate activation, and any of the above invalid values ​​(SLIV or k0, k2) can indicate deactivation. Other various combination indications will not be repeated.

[0160] Scenario 3:

[0161] If the first bandwidth part indicator field (bandwidth part indicator) or the first bitmap is not configured in the first signaling (DCI). When a specific value of the first information field (FDRA of a specific value / invalid value) is used to indicate the activation or deactivation of BWP, the MCS indication field (MCS field) can be used to indicate BWP. For example, when FDRA is set to all 0s, the MCS field indicates an activated BWP, and when FDRA is set to all 1s, the MCS field indicates a deactivated BWP. Similarly, when the first signaling (DCI) can schedule / activate / deactivate multiple BWPs, each FDRA and MCS correspond one-to-one, indicating the activation or deactivation of a BWP respectively. For example, if the first signaling (DCI) FDRA1 is all 0s, FDRA2 is all 0s, and FDRA3 is all 1s, MCS1 indicates BWP0, MCS2 indicates BWP2, and MCS3 indicates BWP3, then the UE activates BWP0 and BWP2 and deactivates BWP3.

[0162] Scenario 4:

[0163] The first signaling includes a second bandwidth part indication field, which includes: a bit for indicating whether a BWP is activated or deactivated, and a bit for indicating whether an activation or deactivation indication is indicated. Specifically, the activation / deactivation bit is merged into the first bandwidth part indication field. For example, if the first bandwidth part indication field uses two bits to indicate the BWP index, the second bandwidth part indication field is now expanded to three bits, with two bits still indicating the BWP index and one bit placed at a specific position (first or last) to indicate the activation or deactivation operation. Similarly, the first signaling includes a second bitmap, which includes: a bit for indicating whether a BWP is activated or deactivated, and a bit for indicating whether an activation or deactivation indication is indicated. For example, if the first bitmap originally used four bits to indicate whether the four configured BWPs are valid, the second bitmap can now be expanded to five bits, with four bits still indicating whether each configured BWP is valid, and the expanded bit placed at a specific position (first or last) to indicate whether the valid BWP is to be activated or deactivated. For example, the bit indicating activation / deactivation is placed at the front of the bitmap (second bitmap). When the DCI bitmap is 01101, the first bit is zero, indicating activation, and the subsequent bits indicate that the activated BWPs are BWP0, BWP1, and BWP3. Later, when the new DCI indication bitmap is 11100, it indicates deactivation of BWP0 and BWP1, while BWP3 remains activated.

[0164] Scene 5:

[0165] The network side device (base station) can instruct the UE to activate / deactivate the BWP through different DCI (both the second signaling and the third signaling are DCI). For example, the bandwidth part indicator or bitmap in the second signaling (scheduling DCI) indicates the BWP to be activated. The bandwidth part indicator or bitmap in the third signaling (non-scheduling DCI) indicates the BWP to be deactivated.

[0166] The base station may also instruct the UE to activate / deactivate the BWP through RRC (the second signaling and the third signaling are both RRC), such as RRC reconfiguration. For example, when the UE receives a new RRC configuration, it activates the BWP indicated in the configuration and deactivates the current BWP.

[0167] Similarly, the base station can instruct the UE to activate / deactivate the BWP through a MAC CE (the second signaling and the third signaling are both MAC CEs).

[0168] Alternatively, the base station instructs the UE to activate a BWP through one of RRC, DCI, and MAC CE, instructs the UE to deactivate the BWP through a signaling different from the BWP activation indication among RRC, DCI, and MAC CE, or uses a timer to activate the BWP.

[0169] Scenario Six:

[0170] Suppose the UE can activate at most three BWPs simultaneously, such as BWP0, BWP1, and BWP2. The size of the first signaling (DCI) supports scheduling three BWPs simultaneously, assumed to be X. If the number of simultaneously scheduled BWPs is less than three, the extra bits are regarded as padding bits. If the base station schedules the UE to transmit on BWP1, the valid bits (bits carrying relevant information for scheduling BWP) indicating the scheduling of BWP1 in the DCI at this time are Y1 bits (Y1 < X). Then, the base station can use the remaining X - Y1 bits to indicate the activation or deactivation of other BWPs. At this time, the base station can schedule the UE to transmit data on BWP1 and indicate the activation of BWP2 (only activation, no scheduling) through the X - Y1 bits. After BWP2 is activated, the base station can schedule the UE to transmit data on BWP1 and BWP2 simultaneously. Suppose the valid bits indicating the scheduling of BWP1 and BWP2 in the DCI at this time are Y2 bits (Y1 < Y2 < X), then the base station can use the remaining X - Y2 bits to indicate the activation or deactivation of other BWPs. After all three BWPs are activated, if the base station only schedules a part of the BWPs, such as BWP1, the base station can use the remaining X - Y1 bits to indicate the deactivation of other BWPs, such as indicating the deactivation of BWP0. Further, if the domains for the DCI to schedule multiple BWPs are independent, that is, BWP0 - BWP3 have their own TDRA, FDRA, MCS, etc. domains (similar to the method in Scenario Two), then at least one of these domains can be set to a special value or an invalid value to indicate the deactivation of the corresponding BWP.

[0171] Scenario Seven:

[0172] The BWPs in all the above scenarios include Downlink (DL) BWPs and Uplink (UL) BWPs. If the BWP for which activation / deactivation is indicated is already in the activated or deactivated state, it continues to maintain the activated or deactivated state without additional operations.

[0173] In summary, the method of the embodiment of the present application can activate or deactivate multiple BWPs, enabling the UE to utilize resources more flexibly and effectively.
