Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a resource activation method, apparatus, terminal, and network-side device. Background Art

[0002] In current communication technologies, only one activated BWP is supported. However, with the development of technologies, it has been possible to obtain more frequency-domain resources by reorganizing existing spectrums. However, the available spectrums in the lower frequency bands with better channel quality are fragmented, and the available spectrum bandwidth of each segment is very small, such as 3 MHz, 4 MHz, 7 MHz, etc. One implementation is to configure the fragmented spectrums as different BWPs. To effectively utilize resources, it may be necessary to simultaneously activate multiple BWPs for data transmission. In addition, for the already activated BWPs, data scheduling does not occur on all activated BWPs at every moment. For example, if BWP1, BWP2, and BWP3 are activated, the data scheduled in slot1 is on BWP1 and BWP2, and in slot2, the scheduled data is on BWP2 and BWP3. The non-scheduled BWPs are not deactivated, which will result in resource waste.

[0003] Therefore, how a terminal can flexibly and effectively utilize resources has become an urgent problem to be solved. Summary of the Invention

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0054] For the convenience of understanding, some content related to the embodiments of this application is described below:

[0055] I. Band Width Part (BWP)

[0056] In New Radio (NR), the network configures one or more BWPs for the User Equipment (UE) to perform data transmission. The BWP is a continuous segment of resources in the frequency domain. The UE realizes dynamic bandwidth changes by activating different BWPs. As Figure 2 shown. At the first moment, the traffic volume of the UE is large, and the UE activates a large bandwidth (BWP1); at the second moment, the traffic volume of the UE is small, and the UE activates a small bandwidth (BWP2) to meet the basic communication requirements; at the third moment, the system discovers that there is a large range of frequency selective fading within the bandwidth where BWP1 is located, or the resources within the frequency range where BWP2 is located are relatively scarce, so the UE is instructed to activate a new bandwidth (BWP3).

[0057] Each BWP can correspond to different configuration parameters, including subcarrier spacing, the position and bandwidth of the BWP, and Cyclic Predix (CP).

[0058] II. Activation / Deactivation of BWP

[0059] The NR UE only supports one active Bandwidth Part (BWP). 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. The scheduling Downlink Control Information (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 active 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 active BWP, the UE switches to the indicated target BWP, that is, deactivates the current BWP and activates the target BWP.

[0060] When the base station configures only one BWP for the UE, it is defaulted that this BWP is 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.

[0061] In addition, the BWP can also be activated through a timer. When the UE activates a BWP, the bwp-InactivityTimer starts timing. Whenever the UE receives DCI scheduling the Physical Downlink Shared Channel (PDSCH) or the Physical Uplink Shared Channel (PUSCH), the UE resets the bwp-InactivityTimer. When the bwp-InactivityTimer expires, the UE switches to the default BWP (if a default BWP is configured) or the initial BWP (if no default BWP is configured).

[0062] In this application, the BWP only represents a part of continuous or discrete resources in the frequency domain, which can be a Resource Block set (RB set), a subband, a carrier, a bandwidth, a BWP, etc.

[0063] In this application, indicating activation or deactivation can also be understood as: indicating that the terminal performs an activation or deactivation operation.

[0064] In this application, the indicated active BWP can also be understood as the BWP to be activated, that is, the BWP has not been activated yet.

[0065] In this application, the indicated BWP identification can also be understood as the indicated BWP.

[0066] Next, in conjunction with the accompanying drawings, the resource activation method, device, terminal, and network-side device provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0067] As Figure 3 shown, a resource activation method according to an embodiment of this application includes:

[0068] Step 301, the terminal activates or deactivates a bandwidth part BWP through at least one of the following methods:

[0069] Receiving a first signaling, where the first signaling is used to indicate activating a first BWP or deactivating a second BWP;

[0070] Receiving a second signaling or a third signaling, where the second signaling is used to indicate activating a third BWP, and the third signaling is used to indicate deactivating a fourth BWP;

[0071] Receiving configuration information or indication information of the activation or deactivation period of a fifth BWP.

[0072] In this way, when the terminal receives at least one of the first signaling indicating activating a first BWP or deactivating a second BWP, or the second signaling indicating activating a third BWP or the third signaling indicating deactivating a fourth BWP, or the configuration information or indication information of the activation or deactivation period of a fifth BWP, it can activate or deactivate the corresponding BWP based on the scheduling situation, enabling the terminal to utilize resources more flexibly and effectively.

[0073] It should be noted that before step 301, the terminal will receive a target signaling (the first signaling, or the second signaling or the third signaling) sent by the network-side device, or configuration information or indication information of the activation or deactivation period of a specific BWP.

[0074] Optionally, in this embodiment, the first signaling is used to indicate activating a first BWP or deactivating a second BWP, which can be understood as that for a BWP, the first signaling can be used to indicate both activation and deactivation. For example, the first signaling can only indicate activating a BWP, or only indicate deactivating a BWP, or indicate both activating and deactivating a BWP.

[0075] Optionally, in this embodiment, the first signaling includes first information and second information. The first information includes indication information for activation or deactivation, and the second information includes information for indicating the identifier of the first BWP or the second BWP.

[0076] That is to say, the first signaling will inform the terminal, through the first information and the second information, which BWPs need to be activated or which BWPs need to be deactivated.

[0077] Among them, the first information and the second information can also be understood as fields carrying corresponding information in the first signaling. The first signaling respectively indicates activation or deactivation, and the BWP identifier through at least one field.

[0078] Optionally, the first information indicates deactivation or maintaining activation of the sixth BWP, and the sixth BWP is the BWP transmitting the first signaling; the identifier of the BWP indicated by the second information is the identifier of the first BWP; or,

[0079] 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,

[0080] the first information indicates whether to deactivate the seventh BWP, or activate the first BWP. The seventh BWP is a BWP other than the first BWP among the activated BWPs, and the first BWP is the default BWP or the initial BWP; the identifier of the BWP indicated by the second information is the identifier of the first BWP.

[0081] Therefore, when the terminal obtains the first information and the second information, when the first information indicates deactivation or maintaining 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 learn from the first information whether to deactivate the BWP transmitting the first signaling, and can learn from the second information which first BWPs are activated; when the first information indicates activation of the first BWP or deactivation of 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 learn from the first information whether the identifier of the BWP indicated by the second information is for deactivating the BWP or activating the BWP, and then can learn from the second information which BWPs to activate or deactivate; 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 learn from the first information whether to deactivate other BWPs except the default BWP or the initial BWP among the activated BWPs (i.e., all activated BWPs), or activate the default BWP or the initial BWP.

[0082] Among them, the first piece of information indicates that activating the default BWP is applicable to the case where the previous default BWP has not been activated, and the first piece of information indicating the activation of the initial BWP is applicable to the case where the default BWP is not configured. Of course, when the first piece of information indicates whether to deactivate the seventh BWP or activate the first BWP, the terminal may ignore the second piece of information.

[0083] Optionally, in this embodiment, the first piece of information is indicated by a specific value in the first information field of the first signaling, or by a dedicated information field of the first signaling.

[0084] That is, 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, setting the FDRA field to a valid value indicates activation, and all 0s or all 1s indicate deactivation. Another example is that in TDRA, k0, k2, or SLIV, valid values, invalid values, or special values indicate activation or deactivation: for example, a valid SLIV or a special SLIV value indicates activation, and an invalid SLIV or a special SLIV value, or k0 or k2 with an infinite value indicates deactivation, etc.

[0085] On the other hand, a new field is added to the first signaling as a dedicated information field to indicate activation or deactivation. For example, a new field is added, and activation or deactivation is indicated by 1 bit: 0 indicates activation, and 1 indicates deactivation.

[0086] Optionally, if simultaneous activation or deactivation of multiple BWPs is supported, the first information field included in the first signaling may be multiple, and each first information field indicates the activation or deactivation of the corresponding BWP.

[0087] Optionally, in this embodiment, the second piece of information is indicated by the first bandwidth part indication field of the first signaling, or by the first bitmap of the first signaling, or by the adjustment and coding strategy indication field of the first signaling.

[0088] Thus, assuming that the second information is indicated by a first bandwidth part indicator, the first information field of the first signaling can indicate whether the BWP for transmitting the first signaling is deactivated by setting a specific value or by the first signaling adding a new field by 1 bit; can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; can indicate whether to deactivate other BWPs among all the activated BWPs except the default BWP or the initial BWP, or activate the default BWP or the initial BWP.

[0089] Assuming that the second information is indicated by a first bitmap, the first information field of the first signaling can indicate whether the BWP for transmitting the first signaling is deactivated by setting a specific value or by the first signaling adding a new field by 1 bit; can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; can indicate whether to deactivate other BWPs among all the activated BWPs except the default BWP or the initial BWP, or activate the default BWP or the initial BWP.

[0090] Assuming that the second information is indicated by a Modulation and Coding Scheme (MCS) indication field, the first information field of the first signaling can indicate whether the BWP for transmitting the first signaling is deactivated by setting a specific value or by the first signaling adding a new field by 1 bit; can indicate whether the BWP indicated by the bandwidth part indicator is deactivated; can indicate whether to deactivate other BWPs among all the activated BWPs except the default BWP or the initial BWP, or activate the default BWP or the initial BWP.

[0091] Optionally, each bit in the first bitmap indicates whether the corresponding BWP is valid in the activation or deactivation operation.

[0092] Wherein, each bit in the first bitmap is associated with a BWP identifier. In this way, the value of the bit indicates whether the BWP corresponding to the bit (having the identifier associated with the bit) is valid in the activation or deactivation operation. Assuming 1 indicates valid and 0 indicates invalid, when the first information indicates activating the first BWP and the first bitmap is 0001, the BWP corresponding to the 4th bit is valid in the activation operation. That is to say, the terminal knows that the first BWP is the BWP having the identifier associated with the 4th bit in the first bitmap.

[0093] Optionally, in this embodiment, the first information and the second information are carried in the padding bits of the first signaling.

[0094] That is, the first signaling indicates the first information and the second information through padding bits.

[0095] Optionally, in this embodiment, the first signaling includes third information and fourth information. The third information includes information for indicating the identifier of the first BWP, and the fourth information includes information for indicating the identifier of the second BWP.

[0096] That is to say, at this time, the first signaling indicates both the identifier of the activated BWP and the identifier of the deactivated BWP.

[0097] Among them, the third information and the fourth information can be understood as fields carrying corresponding information in the first signaling. The first signaling indicates the identifier of the activated BWP and the identifier of the deactivated BWP through at least one field respectively.

[0098] Optionally, the third information and the fourth information are carried in the padding bits of the first signaling; or,

[0099] 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.

[0100] That is, on the one hand, the first signaling indicates the third information and the fourth information through padding bits. On the other hand, the third information and the fourth information are respectively indicated by two first bandwidth part indication fields in the first signaling, or are respectively indicated by two first bitmaps.

[0101] Among them, for the first bandwidth part indication field or the first bitmap indicating the identifier of the deactivated BWP, when there is no need to deactivate any BWP, it can indicate an invalid value or a reserved value or any one or more unactivated BWPs.

[0102] Optionally, in this embodiment, the first signaling includes a second bandwidth part indication field or a second bitmap. The second bandwidth part indication field or the second bitmap includes: bits for indicating the identifier of the first BWP or the second BWP, and bits for indicating an activation indication or a deactivation indication.

[0103] Among them, 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 the addition of bits for indicating an activation indication or a deactivation indication, such as adding 1 bit. Specifically, the specific implementation of the indication by the second bandwidth part indication field or the second bitmap is similar to the implementation in which the first signaling adds a new field to indicate the first information and the second information is indicated by the first bandwidth part indication field or the first bitmap, and will not be elaborated here.

[0104] Optionally, in this embodiment, the padding bit is an idle bit in the first signaling other than the bit carrying the information related to the scheduled BWP.

[0105] That is to say, in the first signaling, the idle bits other than the bits carrying the information related to the scheduled BWP carry the first information and the second information, or carry the third information and the fourth information.

[0106] Among them, the scheduled BWP can also be understood as scheduling the terminal to receive or transmit on the corresponding BWP. The information related to the scheduled BWP includes but is not limited to the identifier of the scheduled BWP, time domain resources, frequency domain resources, etc.

[0107] Among them, the size of the first signaling can be determined by the maximum number of simultaneously activatable BWPs (i.e., the maximum number of activatable BWPs). Moreover, the padding bits carry the first information and the second information, or carry the third information and the fourth information, which is applicable to the case where the number of scheduled BWPs is less than the maximum number of activatable BWPs.

[0108] Optionally, in this embodiment, the first signaling is DCI. Among them, the first signaling can be scheduling DCI; or the first signaling is the first-stage DCI (1st stage DCI), and the second-stage DCI (2nd stage DCI) is used to schedule the BWP.

[0109] Among them, when activated by scheduling DCI, the scheduled BWP is the activated BWP. When deactivating the BWP by using the scheduling DCI, the indication of scheduling resources (such as TDRA, FDRA, etc.) can be ignored.

[0110] Optionally, in this embodiment, the second signaling includes information for indicating the identifier of the third BWP; the third signaling includes information for indicating the identifier of the fourth BWP, or the third signaling is the configuration information of a timer.

[0111] That is, the second signaling is dedicated to indicating activation, and the third signaling is dedicated to indicating deactivation. That is to say, the network-side device can indicate the terminal to activate and deactivate the BWP through at least two signaling.

[0112] Among them, 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 certain BWP is activated, the timer corresponding to the BWP starts timing, and the BWP is deactivated after the timer times out. In addition, whenever the UE receives the DCI for scheduling PDSCH or PUSCH, the timer is reset.

[0113] Among them, the second signaling and the third signaling can indicate the identification of the BWP through a bandwidth part indicator or a bitmap.

[0114] Optionally, the second signaling is a scheduling DCI, and the third signaling is a non-scheduling DCI; or,

[0115] the second signaling is a first-level DCI, and the third signaling is a second-level DCI; or,

[0116] one of the second signaling or the third signaling is a radio resource control (RRC), a DCI, and a media access control - control element (MAC CE).

[0117] Of course, the signaling format implementation of the second signaling and the third signaling is not limited to the above content, and other signaling formats can also be used, which will not be listed one by one here.

[0118] Optionally, the terminal receiving the second signaling or the third signaling includes:

[0119] the terminal receives a scheduling DCI or a non-scheduling DCI, the scheduling DCI is used to activate the BWP, and the non-scheduling DCI is used to deactivate the BWP; or,

[0120] the terminal receives a first-level DCI or a second-level DCI, the first-level DCI is used to activate the BWP, and the second-level DCI is used to deactivate the BWP; or,

[0121] the terminal receives one of an RRC, a DCI, and a MAC CE, or configuration information of a timer, the RRC, the DCI, or the MAC CE is used to activate the BWP, and the timer is used to deactivate the BWP.

[0122] In this way, in one way, the network-side device indicates the activation of the BWP through a scheduling DCI and indicates the deactivation of the BWP through a non-scheduling DCI (such as a group common DCI); in one way, the network-side device indicates the activation of the BWP through a 1st stage DCI 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 indicates the activation of the BWP through an RRC, a DCI, or a MAC CE and indicates the deactivation of the BWP through the configuration information of a timer. Of course, for the network-side device to indicate the activation of the BWP through an RRC, a DCI, or a MAC CE, it can also indicate the activation of the BWP through an RRC or a MAC CE. For example, the RRC is the second signaling and the MAC CE is the third signaling.

[0123] Optionally, in this embodiment, the terminal deactivating the BWP includes:

[0124] When there is only one active BWP and the active BWP is not the default BWP or the initial BWP, deactivate the active BWP and activate the default BWP or the initial BWP at the same time;

[0125] When there is only one active BWP and the active BWP is the default BWP or the initial BWP, keep the active BWP active.

[0126] That is, for the case where there is only one active BWP, the terminal can activate or deactivate the corresponding BWP according to whether the active BWP is the default BWP or the initial BWP.

[0127] Optionally, in this embodiment, the terminal deactivates the BWP by receiving the configuration information of the timer, including:

[0128] When the eighth BWP is not the default BWP or the initial BWP, deactivate the eighth BWP and activate the default BWP or the initial BWP at the same time;

[0129] When the eighth BWP is the default BWP or the initial BWP, keep the eighth BWP active;

[0130] Wherein, the eighth BWP is the only active BWP that needs to be deactivated corresponding to the timer and exists before the timer times out.

[0131] That is, when the 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 active BWP at the current moment, then the BWP is the eighth BWP. The terminal will activate or deactivate the BWP according to whether the BWP is the default BWP or the initial BWP. When the eighth BWP is not the default BWP or the initial BWP, deactivate the eighth BWP and activate the default BWP or the initial BWP at the same time; when the eighth BWP is the default BWP or the initial BWP, keep the eighth BWP active and ignore the timer of the BWP.

[0132] Wherein, if the default BWP is configured, when the eighth BWP is not the default BWP, deactivate the eighth BWP and activate the default BWP at the same time. If the default BWP is not configured, when the eighth BWP is not the initial BWP, deactivate the eighth BWP and activate the initial BWP at the same time.

[0133] Optionally, in this embodiment, the identification of the BWP includes at least one of the following: the identity (ID) of the BWP, and the BWP group index. The BWP group index can also be understood as the BWP set index. For example, the second information includes the index of the BWP group or set. Therefore, if the network device configures a combination of BWPs through RRC, for example, {BWP0, BWP3}, {BWP1, BWP2, BWP3}, etc., each combination corresponds to an index; after receiving the index, the terminal activates or deactivates all BWPs within the combination corresponding to the index.

[0134] Optionally, the configuration information or the indication information includes information for indicating at least one of the following:

[0135] The starting position of the activation or deactivation period;

[0136] The offset of the starting position of the activation or deactivation period;

[0137] The activation time within the activation or deactivation period;

[0138] The deactivation time within the activation or deactivation period;

[0139] The length of the activation or deactivation period.

[0140] Among them, a corresponding activation and deactivation period is set for each BWP (which can also be understood as each BWP combination). In this way, the UE activates or deactivates the BWP within the corresponding period.

[0141] 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. For example, the starting position of the activation or deactivation period of the BWP or BWP combination is a position offset from the start or end position of the even radio frame by offset, or a position offset from the start or end position of the odd radio frame by offset.

[0142] Optionally, in this embodiment, the terminal activates or deactivates the BWP by receiving the configuration information or the indication information, including:

[0143] The terminal activates the fifth BWP at the activation time within the activation or deactivation period and deactivates the fifth BWP at the deactivation time within the activation or deactivation period. The fifth BWP is the BWP corresponding to the activation or deactivation period.

[0144] Here, the activation / deactivation period may include two parts: the activation time and the deactivation time. For example, for a certain BWP or BWP combination, its activation / deactivation period P = activation time Pa + deactivation time Pd. The UE then takes P as the 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 the Pa of at least two BWPs or BWP combinations, then at least two BWPs or BWP combinations will be activated at this time. In addition, the starting position of the activation / deactivation period of the BWP or BWP combination can also be configured. The starting position can be defined by the offset from the radio frame. For example, the starting position of the activation / deactivation period of the BWP or BWP combination is offset from the start / end position of the even / odd radio frame.

[0145] In this embodiment, the first BWP, the second BWP, the third BWP, the fourth BWP, the fifth BWP, etc., can all be one or more BWPs, BWP groups, or BWP sets unless otherwise specified.

[0146] 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.

[0147] Next, the application of the embodiments of the present application will be described in combination with specific scenarios:

[0148] Scenario 1:

[0149] Suppose the base station configures four BWPs for UE1, namely BWP0 - BWP3, where BWP0 is the initial BWP and BWP3 is the default BWP. The base station uses two fields in the DCI (the first signaling) (one field indicates the first information and one field indicates the second information) to instruct the UE to activate the corresponding BWP and deactivate the corresponding BWP.

[0150] For example, when FDRA is set to all 0s, or FRDA is set to a valid value, or the new field (referred to as the activation / deactivation field) has a value of 0, at this time, the first information indicates to keep the BWP that transmits the first signaling activated. The base station sends the above indication on the initial BWP0; and the first bandwidth part indicator indicates 2 (indicating the activation of BWP2), or the first bitmap is set to 0010 (indicating that the activation operation takes effect for BWP2), then the UE activates BWP2 and keeps BWP0 activated.

[0151] After that, 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 has a value of 1, the base station sends the above indication on BWP0, and the bandwidth part indicator indicates 2, or the bitmap is set to 0010, then the UE can perform one of the following operations:

[0152] 1. Deactivate BWP0 and keep BWP2 active (the first information indicates deactivating the BWP that transmits the first signaling, and the identifier of the BWP indicated by the second information is the identifier of the active BWP);

[0153] 2. Deactivate BWP2 and keep BWP0 active (the first information indicates activating the initial BWP, and the identifier of the BWP indicated by the second information is the identifier of the deactivated BWP);

[0154] 3. Deactivate BWP0 and BWP2 and activate BWP3 (the first information indicates deactivating the BWPs other than the default BWP among the already active BWPs, and the second information indicates activating the default BWP).

[0155] Scenario 2:

[0156] When the first information domain (FDRA domain) is used to indicate the first information (activating or deactivating a BWP), and a first bitmap is used to indicate the BWP, if multiple BWPs are supported to be activated or deactivated simultaneously, that is, a DCI can schedule or indicate multiple BWPs, then the value of each FDRA domain respectively indicates the activation or deactivation of the corresponding BWP. Assume the BWP configuration is as in Scenario 1, and the UE transmits on BWP0 after initial access. Assume the UE can activate at most 3 BWPs simultaneously. Then the FDRA domain in the DCI includes FDRA1, FDRA2, and FDRA3, which respectively correspond to the frequency domain resource indication of each active BWP. The values of FDRA1 - FDRA3 are each all 0s or all 1s. When the valid value or all 0s / all 1s are used, the three corresponding BWPs are activated or deactivated respectively. For example, using the valid value of FDRA to indicate activation and the invalid value to indicate deactivation, if FDRA1 is a valid value, FDRA2 is a valid value, FDRA3 is all 0s / all 1s, and the first bitmap is set to 1010, then at this time the UE keeps BWP0 active and newly activates BWP2; after that, in the newly received DCI, FDRA1 is all 0s / all 1s, FDRA2 is all 0s / all 1s, FDRA3 is a valid value, and the first bitmap is set to 1011, then at this time the UE deactivates BWP0 and BWP2 and activates BWP3. The FDRA set to a valid value indicates the frequency domain resource scheduling on the corresponding BWP.

[0157] Similarly, assuming that each BWP corresponds to its own TDRA field, the BWP can be activated and deactivated using TDRA. Only the activation and deactivation indications are exemplified here, and the indications of the BWP will not be elaborated further. Since there are invalid values / invalid combinations in the SLIV, the activation or deactivation of the BWP can be indicated by these special values / combinations in the invalid values / invalid combinations. For example, the SLIV value / combination 1 indicates activation, and the value / combination 2 indicates deactivation. The activation and deactivation can also be indicated by special values of k0 or k2. For example, when the value of k0 is infinite, it indicates activation, and when the value of k2 is infinite, it indicates deactivation. Or when both values are infinite, it indicates deactivation. Further, the activation can also be indicated by all valid values of TDRA, and any of the above invalid values (SLIV or k0, k2) indicates deactivation. Other various combination indications will not be elaborated further.

[0158] Scenario Three:

[0159] If the first signaling (DCI) does not configure the first bandwidth part indicator field (bandwidth part indicator) or the first bitmap. When using a specific value (specific value / invalid value of FDRA) in the first information field to indicate the activation and deactivation of the BWP, the MCS indicator field (MCS field) can be used to indicate the BWP. For example, when the FDRA is set to all 0s, the MCS field indicates an activated BWP, and when the 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 corresponds one-to-one with an MCS, respectively indicating the activation or deactivation of a BWP. For example, if the first signaling (DCI) FDRA1 is all 0s, FDRA2 is all 0s, FDRA3 is all 1s, MCS1 indicates BWP0, MCS2 indicates BWP2, and MCS3 indicates BWP3, then the UE activates BWP0 and BWP2 and deactivates BWP3.

[0160] Scenario Four:

[0161] The first signaling includes that the second bandwidth part indication field includes: bits for indicating the identifier for activating or deactivating a BWP, and bits for indicating an activation indication or a deactivation indication. That is, the bits for indicating activation / deactivation are merged into the first bandwidth part indication field. For example, if the first bandwidth part indication field uses 2 bits to indicate the BWP index, now the second bandwidth part indication field becomes 3 bits, where 2 bits are still used to indicate the BWP index, and the other bit is placed at a specific position (the front or the end) to indicate an activation or deactivation operation. Similarly, the first signaling includes the second bitmap which includes: bits for indicating the identifier for activating or deactivating a BWP, and bits for indicating an activation indication or a deactivation indication. That is, if the original 4-bit first bitmap is used to indicate whether the 4 configured BWPs are effective, now the second bitmap can be extended to 5 bits, where 4 bits still indicate whether each of the configured BWPs is effective, and the extended 1 bit is placed at a specific position (the front or the end) to indicate an activation or deactivation operation for the effective BWP. For example, the bit for indicating an activation indication / deactivation indication is placed at the front of the bitmap (the second bitmap). When the DCI's bitmap is 01101, the first bit is 0, indicating activation, and the subsequent bits indicate that the activated BWPs are BWP0, BWP1, and BWP3. Then, when the new DCI indicates that the bitmap is 11100, it means to deactivate BWP0 and BWP1, and at this time BWP3 remains in the activated state.

[0162] Scenario Five:

[0163] The network side device (base station) can indicate to the UE to activate / deactivate a BWP through different DCIs (both the second signaling and the third signaling are DCIs). For example, the bandwidth part indicator or the bitmap in the second signaling (scheduling DCI) indicates the BWP to be activated. The bandwidth part indicator or the bitmap in the third signaling (non-scheduling DCI) indicates the BWP to be deactivated.

[0164] The base station can also indicate to the UE to activate / deactivate a BWP through RRC (both the second signaling and the third signaling are 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.

[0165] Similarly, the base station can indicate to the UE to activate / deactivate a BWP through MAC CE (both the second signaling and the third signaling are MAC CE).

[0166] 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 in RRC, DCI, and MAC CE, or uses a timer to activate the BWP.

[0167] Scenario 6:

[0168] It is assumed that 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. Assume that 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 2), special values or invalid values can be taken for at least one of these domains to indicate the deactivation of the corresponding BWP.

[0169] Scenario 7:

[0170] The BWPs in all the above scenarios include DL BWP and UL BWP. If the BWP whose activation / deactivation is indicated is already in the activated or deactivated state, it continues to maintain the activated or deactivated state without additional operations.

[0171] In summary, the method of the embodiment of the present application can activate or deactivate multiple BWPs, enabling the UE to more flexibly and effectively utilize resources.
