[0091] For terminals supporting secondary cell (SCell) dormancy, at least two bandwidth parts (BWPs) need to be configured on that SCell: one dormant BWP and the others non-dormant BWPs. The non-dormant BWPs include a first outside active time (FIG) BWP. Network devices can instruct terminals to switch between dormant and non-dormant BWPs based on downlink control information (DCI). The DCI indication field can contain multiple bits, each corresponding to a SCell or a SCell group. A bit displaying '0' indicates that the active BWP of the terminal's corresponding SCell or SCell group is a dormant BWP; a bit displaying '1' indicates that the active BWP of the terminal's corresponding SCell or SCell group is the first outside active time (if the terminal's current active BWP is a dormant BWP), or indicates that the active BWP of the terminal's corresponding SCell or SCell group is the currently active BWP (if the terminal's current active BWP is not a dormant BWP).

[0092] For terminals supporting SCell dormancy, when a SCell is on a dormant BWP, the network device needs to first switch the terminal from the dormant BWP to a non-dormant BWP before the network device can trigger the terminal to measure CSI-RS or transmit SRS for CSI measurement on the non-dormant BWP of the SCell. After obtaining the CSI information, the network device can determine a suitable modulation and coding scheme (MCS) to schedule resources on the non-dormant BWP of that SCell for data transmission by the terminal. Otherwise, the base station can only schedule data transmission based on the default CSI. If the default CSI is poor, the terminal transmission rate will be low; if the default CSI is high, the decoding success rate will be low, resulting in a still low transmission rate.

[0093] In related technologies, when a terminal's SCell has just switched to a non-sleep BWP, the CSI on the non-sleep BWP of the SCell cannot be obtained in time, affecting the data transmission rate. To enable the terminal to obtain the CSI in advance, it is desirable to trigger CSI measurement and / or CSI transmission when the SCell is indicated by the non-sleep BWP. How to trigger CSI measurement and / or CSI transmission when the SCell is indicated by the non-sleep BWP is a technical problem that needs to be solved.

[0094] Figure 2 This is an interactive schematic diagram illustrating a communication method according to an embodiment of this disclosure. For example... Figure 2 As shown, the embodiments of this disclosure relate to a communication method, which includes: Step S2101: The terminal sends the second information to the network device.

[0095] In some embodiments, the network device receives second information sent by the terminal.

[0096] In some embodiments, the second information is used to indicate that the terminal supports a first feature; wherein the first feature includes at least one of the following: early CSI triggering; early CSI-RS triggering; early SRS triggering.

[0097] CSI triggering can be triggered by a CSI report. The CSI report includes at least one of the following: precoding matrix indicator (PMI), channel quality indicator (CQI), CSI-RS resource indicator (CRI), layer indicator (LI), and rank indicator (RI).

[0098] For example, the terminal supports early CSI triggering, or the terminal supports early CSI-RS triggering, or the terminal supports early SRS triggering, or the terminal supports both early CSI triggering and early CSI-RS triggering, or the terminal supports both early CSI triggering and early SRS triggering, or the terminal supports both CSI-RS triggering and early SRS triggering, or the terminal supports early CSI triggering, CSI-RS triggering, and early SRS triggering.

[0099] Among them, early CSI triggering can be triggered by the DCI where the SCell hibernation indicator is located, early CSI-RS triggering can be triggered by the DCI where the SCell hibernation indicator is located, and early SRS triggering can be triggered by the DCI where the SCell hibernation indicator is located.

[0100] In step S2102, the network device sends third information to the terminal.

[0101] In some embodiments, the terminal receives third information sent by the network device.

[0102] In some embodiments, the third information is carried in radio resource control (RRC) signaling, and the third information is used to indicate that at least one of the following is triggered after the terminal receives the first information: transmission of SRS, transmission of CSI, and reception of CSI-RS.

[0103] In some embodiments, the network device may indicate to the terminal via third information whether to trigger at least one of SRS transmission, CSI transmission, and CSI-RS reception after receiving the first information.

[0104] For example, if the third information indicates that the CSI is triggered after the terminal receives the first information, then the terminal sends the CSI of the first SCell after receiving the first information.

[0105] For example, if the third information indicates that the terminal triggers the reception of CSI-RS after receiving the first information, then the terminal receives the CSI-RS corresponding to the first SCell after receiving the first information.

[0106] In some embodiments, RRC signaling may include CSI report configuration information and / or CSI-RS resource configuration information. The CSI report configuration information and / or CSI-RS resource configuration information includes at least one of the following: CSI-RS resource set identifier; CSI-RS resource identifier; CSI-RS time-domain resources; CSI-RS time-domain characteristics; CSI-RS frequency-domain resources; number of CSI-RS ports; whether the CSI-RS follows a unified TCI state; the TCI state adopted by the CSI-RS; power control offset value; scrambling code; trigger state, where the trigger state corresponds to one or more CSI report configuration identifiers; CSI report configuration identifier, where the CSI report configuration identifier corresponds to the CSI-RS resource set identifier and / or CSI-RS resource identifier; codebook configuration; codebook subset restrictions; reporting resources, including the Physical Uplink Control Channel (PUCCH) and / or the Physical Uplink Shared Channel (PUSCH); reporting time-domain characteristics; and reporting quantity.

[0107] CSI-RS can choose to follow a unified TCI state or not. For a single TRP, there is only one indicated TCI state, so only whether CSI-RS follows a unified TCI state needs to be configured. If it follows a unified TCI state, there is no need to configure the TCI state or spatial relation information separately; if it does not follow a unified TCI state, then the TCI state or spatial relation information needs to be configured separately.

[0108] Among them, the RS corresponding to the QCL type of TCI status or spatial relationship information can be the SSB or CSI-RS resource index of the corresponding SCell or the SSB or CSI-RS resource index of other serving cells.

[0109] In the case of multiple TRP scenarios, there are two TCI states. The TCI state used by CSI-RS can be either the first TCI state or the second TCI state.

[0110] The codebook configuration may include at least one of the following: Type I; Type II; single panel; multiple panel; port selection; coherent joint transmission (CJT); Doppler; and codebook mode.

[0111] The reported quantity refers to the content of the CSI report, which may include at least one of the following: channel quality indicator (CQI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), and precoding matrix indicator (PMI).

[0112] For example, if the third information indicates that the SRS is triggered after the terminal receives the first information, then after receiving the first information, the terminal sends the SRS for the SCell corresponding to the non-dormant BWP.

[0113] In some embodiments, RRC signaling may include SRS resource information, which includes at least one of the following: SRS resource set identifier; SRS resource identifier; SRS time-domain resources; SRS time-domain characteristics; SRS frequency-domain resources; comb offset; repetition factor; frequency hopping mode; purpose; number of SRS ports; whether the SRS follows a unified TCI state; the TCI state adopted by the SRS; SRS power-related parameters; path loss reference; reference signal resources; sequence identifier.

[0114] In some embodiments, the RRC signaling that includes SRS resource information may be a system information block or other RRC signaling.

[0115] The time-domain characteristics of SRS can be periodic, semi-persistent, or aperiodic.

[0116] One example use of SRS resources is antenna switching.

[0117] The SRS can follow a unified TCI state or not. For a single TRP (sTRP), there is only one indicated TCI state, so only whether the SRS follows a unified TCI state needs to be configured. If it follows a unified TCI state, there is no need to configure the TCI state or spatial relation information separately; if it does not follow a unified TCI state, then the TCI state or spatial relation information needs to be configured separately.

[0118] Among them, the RS corresponding to the QCL type of TCI status or spatial relationship information can be the SSB or CSI-RS resource index of the SCell or the SSB or CSI-RS resource index of other serving cells.

[0119] In the case of multiple TRP scenarios, there are two indicated TCI states. The TCI state used by SRS can be either the first TCI state or the second TCI state.

[0120] The power-related parameters of SRS may include path loss compensation factor (alpha) and target received power (P0).

[0121] The path loss reference signal resource can be the path loss reference RS; the RS can be the SSB or CSI-RS resource index of the SCell or the SSB / CSI-RS resource index of another serving cell; if the TCI status includes power-related parameters and path loss reference RS, it does not need to be given separately.

[0122] In step S2103, the network device sends the first information to the terminal.

[0123] In some embodiments, the terminal receives first information sent by the network device.

[0124] In some embodiments, the network device that sends the first information may be the network device corresponding to the primary cell (PCell).

[0125] In some embodiments, the network device that sends the first information may be the network device corresponding to the secondary cell (SCell).

[0126] The first information includes a first information field, which is used to indicate whether the SCell is in sleep mode, and the first information is used to indicate at least one of the CSI-RS reception and CSI transmission corresponding to the first SCell.

[0127] In some embodiments, the CSI-RS received by the terminal may be sent by the network device corresponding to the first SCell.

[0128] In some embodiments, the terminal may send CSI to the network device corresponding to the first SCell or to the network device corresponding to the PCell.

[0129] In some embodiments, CSI can be a CSI report.

[0130] In some embodiments, the first SCell is at least one SCell indicating that the BWP is a non-dormant BWP and the current BWP is a dormant BWP.

[0131] In some embodiments, the currently active BWP of the first SCell is a dormant BWP, and the first information field indicates that the active BWP of the first SCell is a non-dormant BWP.

[0132] In other words, the current BWP of the first SCell is a dormant BWP, and the first information field indicates that the dormant BWP of the first SCell should be switched to a non-dormant BWP. The first SCell can be one or more.

[0133] In some embodiments, the first information is carried in downlink control information (DCI).

[0134] In some embodiments, the DCI format corresponding to the first information is one of the following: DCI format 0_1; DCI format 0_3; DCI format 1_1; DCI format 1_3; DCI format 2_6.

[0135] In some embodiments, the first information field is a SCell sleep indicator; or, the first information field includes at least one of the following: the modulation and coding scheme (MCS) of transport block 1 (TB1); the new data indicator of TB1; the redundancy version of TB1; the hybrid automatic repeat request (HARQ) process number; the antenna port; and the demodulation reference signal (DMRS) sequence initialization.

[0136] For example, when the DCI format corresponding to the first information is one of DCI format0_1, DCI format0_3, DCI format1_1, DCI format1_3, or DCI format2_6, the first information field can be a SCell dormancy indication. The number of bits in the first information field can be determined based on the number of dormancy group IDs configured in the RRC signaling, with each group ID corresponding to one bit and each group ID corresponding to one SCell group.

[0137] For example, when the DCI format corresponding to the first information is DCI format 1_1 or DCI format 1_3, DCI does not schedule physical downlink shared channel (PDSCH) reception. The first information field may include at least one of the following: TB1 MCS; TB1 new data indication; TB1 redundant version; HARQ process number; antenna port; DMRS sequence initialization. Each bit of the first information field may correspond to one SCell or SCell group.

[0138] In some embodiments, the first information is used to instruct the CSI corresponding to the first SCell to be sent.

[0139] In some embodiments, the DCI format corresponding to the first information is one of DCI format 0_1 ​​and DCI format 0_3, and the first information includes a CSI request field, which is used to indicate the transmission of CSI corresponding to the first SCell.

[0140] For example, when the DCI format corresponding to the first information is either DCI format 0_1 ​​or DCI format 0_3, these DCI formats all include a CSI request field, and the first information includes the original CSI request field in these DCI formats. Furthermore, these DCI formats can also indicate PUSCH resources, which are used to send CSIs. In other words, the CSI request field is used not only to request CSIs on the PCell, but also to request CSIs on at least one SCell contained in the first SCell.

[0141] In some embodiments, different code points in a CSI request domain correspond to different CSI report configurations, and the correspondence between code points and CSI report configurations is configured by RRC.

[0142] In some embodiments, the first information is used to instruct the CSI corresponding to the first SCell to be sent.

[0143] In some embodiments, the DCI format corresponding to the first information is one of DCI format 1_1, DCI format 1_3, and DCI format 2_6. The first information includes a second information field and / or a third information field. The second information field is used to indicate the CSI transmission corresponding to the first SCell, and the third information field is used to indicate the PUSCH resource for transmitting the CSI.

[0144] For example, the DCI format corresponding to the first information may be one of DCI format 1_1, DCI format 1_3, or DCI format 2_6. These DCI formats do not have a CSI request field and cannot indicate the PUSCH resource for sending the CSI. A new CSI request field can be introduced into this DCI format. For ease of distinction, the newly introduced CSI request field is called the second information field, and the newly introduced information field for indicating the PUSCH resource is called the third information field. The first information includes the second information field and / or the third information field. The second information field is used to indicate the CSI transmission corresponding to the first SCell, and the third information field is used to indicate the PUSCH resource for sending the CSI. That is, the second information field is used to request the CSI on at least one SCell contained in the first SCell, and the third information field is used to indicate the transmission resource for the CSI on at least one SCell contained in the first SCell.

[0145] In some embodiments, different trigger states correspond to different code points in the CSI request field or the second information field. The CSI report configuration is determined based on the trigger state, and the CSI transmission is determined based on the CSI report configuration.

[0146] In some embodiments, the first information indicates one of the active trigger states, which is activated by the medium access control element (MAC CE) from the trigger state list, which is configured by RRC.

[0147] For example, different code points correspond to different trigger states. If the trigger state list configured by RRC contains more than 2^N-1 trigger states, where N is the number of bits requested by CSI (where all 0 bits of the code point indicate no CSI trigger), then MAC CE is needed to activate no more than 2^N-1 trigger states in the trigger state list. Then, the CSI request field or the second information field of DCI indicates one of the activated trigger states.

[0148] In some embodiments, the first information field is used to indicate that the active BWP of a plurality of SCells is a non-dormant BWP.

[0149] For example, the first information field includes multiple bits, each bit indicating that the active BWP of a SCell or group of SCells is a non-dormant BWP. That is, the first information field can indicate that the active BWP of multiple SCells is a non-dormant BWP. Among them, the first SCell is at least one SCell among multiple SCells whose current BWP is a dormant BWP.

[0150] In some embodiments, the method may further include at least one of the following: The reception of CSI-RS and / or transmission of CSI on the first SCell contained in different SCells or different SCell groups are determined based on an information field in the first information. Based on the different information fields in the first information, the reception of CSI-RS and / or the transmission of CSI on the first SCell contained in different SCells or different SCell groups are determined respectively; The reception of CSI-RS and / or transmission of CSI on a specified SCell or the first SCell in a specified SCell or group of SCells is determined based on an information field in the first information.

[0151] For example, multiple SCells or multiple SCell groups can be indicated by the same information field in the first information. This same information field is the same as the information field indicating the PCell, and this information field can be the CSI request field used for the PCell's CSI request. The multiple SCells can belong to the same cell group or different cell groups, i.e., the same bit or different bits in the CSI request fields corresponding to the multiple SCells. This same information field is used to trigger CSI reporting for both the PCell and the first SCell.

[0152] For example, multiple SCells or multiple SCell groups can be indicated by the same information field in the first information. This same information field is different from the information field indicating the PCell. That is, the first information may include two information fields: one for indicating the reception of CSI-RS and / or the transmission of CSI on multiple SCells or multiple SCell groups, and the other for indicating the reception of CSI-RS and / or the transmission of CSI on the PCell. The multiple SCells may belong to the same cell group or different cell groups, meaning that the multiple SCells correspond to the same or different bits in the CSI request field.

[0153] For example, multiple SCells or multiple SCell groups can be indicated by different information fields in the first information, with each information field corresponding to one SCell or one SCell group. These multiple different information fields can be newly introduced information fields, different from the information field used to indicate PCells. For example, the first information includes a first sub-information field and a second sub-information field, where the first sub-information field is used to indicate the reception of CSI-RS and / or the transmission of CSI corresponding to the first SCell or the first SCell group, and the second sub-information field is used to indicate the reception of CSI-RS and / or the transmission of CSI corresponding to the second SCell or the second SCell group.

[0154] For example, a specific SCell or SCell group among multiple SCells or SCell groups can be indicated by an information field in the first information. This information field can be the same as or different from the information field indicating the PCell. For example, the index of a specific SCell or SCell group can be determined based on the carrier indication in the DCI, in which case the carrier indication exists and is not 0 (the PCell corresponding to the absence of a carrier indication or a carrier indication of 0). That is, the reception of CSI-RS and / or the transmission of CSI indicated by the information field in the first information only applies to the reception of CSI-RS and / or the transmission of CSI on the specified SCell in at least one of the first SCells where the active BWP indicated by the first information is a non-dormant BWP and the current BWP is a dormant BWP. Which SCell is the specified SCell can be based on protocol conventions or RRC configuration, such as the specified SCell being the SCell with the smallest cellindex among the first SCells.

[0155] In some embodiments, DCI format 1_1 or DCI format 1_3 may be a DCI for which PDSCH reception is not scheduled, and the carrier indication may indicate the SCell index corresponding to the SCell index applicable to the CSI request field.

[0156] In some embodiments, DCI format 1_1 or DCI format 1_3 may be a DCI that schedules PDSCH reception and defaults to scheduling PDSCH reception of PCell. The carrier indication may indicate the SCell index, corresponding to the SCell index applicable to the CSI request field.

[0157] In some embodiments, the method by which the SCell is indicated can be configured via RRC signaling.

[0158] In some embodiments, the method may further include: in response to the first information including a first information field, determining the reception of CSI-RS or the transmission of the corresponding CSI for the first SCell; the first SCell is the SCell indicated by the first information field where the active BWP is a non-dormant BWP and the current BWP is a dormant BWP.

[0159] In some embodiments, a terminal can determine to receive CSI-RS on the first SCell and / or send a CSI report corresponding to the first SCell simply by receiving a first information field in the first information indicating whether to sleep. That is, additional indications in the first information are not required; for example, the inclusion of a CSI request field in the first information is not necessary, and the relevant CSI report configuration information or CSI-RS resource configuration information can be determined based on protocol agreements or RRC signaling. Whether the terminal triggers the reception of CSI-RS and / or the transmission of a CSI report on the first SCell after receiving the first information containing the first information field indicating whether to sleep can be configured by the third information.

[0160] In some embodiments, the method may further include: determining CSI report configuration information or CSI-RS resource configuration information based on protocol agreement or received RRC signaling.

[0161] In some embodiments, RRC signaling may be UE-specific RRC signaling or a system information block (SIB).

[0162] For example, the protocol or RRC signaling may specify a default set of CSI report configuration information or CSI-RS resource configuration information specifically used when emerging from SCell hibernation; or the protocol or RRC may specify multiple sets of CSI report configuration information or CSI-RS resource configuration information, with the set with the smallest ID being the default set used when emerging from SCell hibernation.

[0163] In some embodiments, the terminal receives the CSI-RS corresponding to the first SCell and / or sends the CSI corresponding to the first SCell based on CSI-RS resource configuration information or CSI report configuration information.

[0164] The communication method provided in this embodiment includes a terminal receiving first information, which includes a first information field indicating whether the SCell is in sleep mode. The first information field also indicates at least one of receiving CSI-RS and transmitting CSI corresponding to the first SCell, thereby enabling the terminal to transmit data with the SCell as soon as possible based on accurate CSI after the SCell goes out of sleep, thus improving communication efficiency.

[0165] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, step S2103 may be implemented as a standalone embodiment, steps S2101+S2103 may be implemented as standalone embodiments, and steps S2102+S2103 may be implemented as standalone embodiments, but are not limited thereto.

[0198] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0199] This disclosure proposes a communication method that triggers CSI-RS measurement / CSI reporting simultaneously with the non-sleep BWP indication in SCell, ensuring that the terminal can perform data scheduling as quickly as possible based on accurate CSI after completing the non-sleep BWP handover in SCell, thereby improving the data transmission rate.

[0200] The communication method provided in this disclosure may include at least one of the following: 1) The terminal receives first information, which is used to indicate at least one of CSI-RS reception and CSI (report) request, and the first information is carried by DCI.

[0201] a) The first information carries an information field for indicating SCell dormancy.

[0202] 2) Based on 1), the first information is DCI format 0_1, DCI format 0_3, DCI format 1_1, DCI format 1_3, DCI format 2_6.

[0203] a) DCI format 0_1, DCI format 0_3, The information field of the i.SCell dormancy indication is the SCell dormancy indication field. Its number of bits is determined based on the number of DormancyGroupID(s) configured in the RRC signaling, with 1 bit corresponding to each group ID and each group ID corresponding to one SCell group.

[0204] b) DCI format 1_1, DCI format 1_3, i. The information field indicated by the SCell dormancy is the SCell dormancy indication. See above for details.

[0205] ii. Or the information field indicated by the SCell dormancy is as follows, in which case DCI does not schedule PDSCH reception. In this case, a single HARQ-ACK request is absent or set to '0', and all frequency domain resource allocation bits are set to 0 for resource allocation type 0, 1 for resource allocation type 1, or 0 or 1 for dynamic switch resource allocation type. Each bit in the following fields corresponds to one SCell.

[0206] The modulation and coding scheme of transport block 1. New data indicator of transport block 1; Redundancy version of transport block 1. HARQ process number; Antenna port(s) DMRS sequence initialization.

[0207] c) DCI format 2_6.

[0208] i. Same as DCI format 0_1, DCI format 0_3.

[0209] 3) Based on 1) or 2), the first information is used to indicate a CSI request. This first information includes DCI format0_1 and DCI format0_3. These two formats inherently contain a CSI request field, and they can also indicate the PUSCH resources used for sending CSI reports. The first information includes a CSI request field. Different code points in the CSI request field correspond to different CSI trigger states. Different CSI trigger states correspond to one or more CSIreport configs, and the correspondence is configured by RRC.

[0210] 4) Based on 1) or 2), the first information is used to indicate the CSI request. The first information includes DCI format1_1, DCI format 1_3, and DCI format 2_6. These three formats originally did not have a CSI request field and could not indicate the PUSCH resources used for CSI report transmission. Therefore, if these three formats are used, two new fields need to be introduced: one for CSI request and the other for PUSCH time domain resource allocation and frequency domain resource allocation.

[0211] 5) Based on 3) or 4), different code points correspond to different trigger states. If the trigger state list configured by RRC contains more than 2^N-1 trigger states, where N is the number of bits in the CSI request (because all code points are 0 and CSI is not triggered), then MAC CE needs to activate no more than 2^N-1 trigger states in the list, and then the CSI request of DCI indicates one of the activated trigger states.

[0212] 6) Based on 5), the detailed configuration of the CSI report configuration corresponding to the trigger state is determined according to RRC and includes: receiving RRC signaling (UE-specific RRC signaling or SIB system information block), wherein the RRC signaling includes at least one of the following parameters corresponding to the CSI report configuration.

[0213] a) First, the resource-related parameters: i.CSI-RS resource set ID, ii.CSI-RS resource ID in CSI-RS resource set, iii. Time-domain resources of CSI-RS iv. Time-domain characteristics of CSI-RS: periodic, semi-persistent, or aperiodic. v.CSI-RS frequency domain resources, vi. Number of CSI-RS ports vii. Whether the CSI-RS follows the unified TCI state (in sTRP, there is only one indicated TCI state, so only whether to follow is required). If not, configure its TCI state separately. 1. The RS corresponding to the QCL type of the TCI state can be the SSB / CSI-RS resource index of this SCell or the SSB / CSI-RS resource index of other serving cells.

[0214] viii. CSI-RS applyIndicatedTCI-State-r18, apply the first or the second TCI state (in mTRP, there are two indicated TCI states, so it is necessary to indicate whether to use the first or the second).

[0215] ix. Power control offset value, x. Scrambling code.

[0216] b) Report relevant parameters: i. Trigger state: corresponds to one or more CSI report config IDs.

[0217] ii. CSI report config ID, which corresponds to CSI-RS resource set ID and / or CSI-RSresource ID.

[0218] iii. Codebook configuration, Type I; Type II; single panel; multiple panel; port selection; coherent joint transmission (CJT); Doppler.

[0219] iv. Codebook subset restriction, v. Report resources: PUCCH / PUSCH vi. Report time-domain characteristics: periodic, semi-persistent, or aperiodic. vii. Reported Quantity: Channel quality indicator (CQI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), and precoding matrix indicator (PMI).

[0220] 7) Based on 1)-5), since SCell dormancy contains multiple bits, it's possible to simultaneously indicate that multiple SCells have active BWPs that are not dormant. In this case, which of the following SCells, PCells, or SCell groups does the CSI request field apply to: a) There is only one CSI request domain in the DCI: i. DCI format 0_1 / 0_3: This DCI format already contains a CSI request field, meaning it reuses that field; 1. This CSI request field is used to trigger CSI reporting for all SCells where the PCell indicated by the first information is a non-dormant BWP and the current BWP is a dormant BWP (only these SCells are transitioning from a dormant BWP to a non-dormant BWP. For SCells where the first information indicates an activated BWP and the current BWP is a non-dormant BWP, there are other specific messages to trigger this. Therefore, the phrase "all active BWPs are non-dormant BWPs" refers to SCells where the current BWP is a dormant BWP). That is, the corresponding CSI request fields are the same, indicating a codepoint. However, the CSI report configurations for the PCell and different SCells or SCell groups corresponding to the same codepoint can be different.

[0221] a) where multiple SCells are multiple SCells within a single cell group. 2. Or the CSI request domain applies to one of multiple SCells. a) For example, the index of the SCell is based on the carrier indicator in the DCI. At this time, the carrier indicator in the DCI exists and the indicator is non-zero, because the absence of the carrier indicator or the indicator being zero corresponds to the PCell.

[0222] i. In other words, which SCell it applies to is determined by the carrier indicator.

[0223] 1. The CSI request domain may or may not apply to PCell, depending on the default rules or RRC instructions.

[0224] b) For example, the SCell index is based on the cell index of the SCell indicated by the new indicator field in the DCI, which is independent of the carrier indicator in the DCI.

[0225] c) The index of an SCell is determined based on default rules, such as the active BWP of multiple SCells being the one with the smallest cell index among the non-dormant BWPs.

[0226] ii. DCI format 1_1 / 1_3 / 2_6: This DCI format originally did not have a CSI request field, so a new field needs to be introduced. In this case, the method corresponding to DCI format 0_1 / 0_3 can be reused, but the difference is that this field is not applicable to PCells, but only to all SCells or one of the SCells.

[0227] 1. In this case, DCI format 1_1 / 1_3 can be a DCI that does not schedule PDSCH reception, and the carrier indicator can indicate the SCell index, which corresponds to the SCell index applicable to the CSI request.

[0228] 2. In this case, DCI format 1_1 / 1_3 can be the DCI for scheduling PDSCH reception, and by default it is the PDSCH reception for scheduling PCell, while the carrier indicator can indicate the Scell ​​SCell index, which corresponds to the SCell index applicable to CSIrequest.

[0229] b) There are multiple CSI request domains in the DCI. i. DCI format 0_1 / 0_3: This DCI format already has a CSI request field, which is reused, and one or more new second CSI request fields are introduced. 1. Compared to the single CSI request field in DCI, the original CSI request field was used to trigger PCells. One or more new SCells are introduced for all active BWPs that are not dormant. Similar to the previous approach, if a new SCell is introduced, it can be applied to all SCells, or a specific SCell can be determined based on the previous method. If each SCell or SCellgroup corresponds to a CSI request field, it is indicated independently.

[0230] ii. DCI format 1_1 / 1_3 / 2_6: This DCI format originally did not have a CSI request field, so multiple new fields need to be introduced. In this case, different fields correspond to different SCells or SCell groups.

[0231] c) Whether the above refers to the same domain, multiple different domains, or, if it refers to the same domain, which of the PCells and at least one SCell the domain applies to, can be determined by the network device through RRC configuration.

[0232] 8) Based on 1 or 2, the terminal sends second information, the second information being used to indicate that the terminal supports a first feature, the first feature being at least one of the following: a) Early CSI triggering: i. Triggered via the DCI where the SCell dormancy indicator is located. b) Early triggering of CSI-RS i. Triggered via the DCI where the SCell dormancy indicator is located. c) Early triggering of SRS i. Triggered via the DCI where the SCell dormancy indicator is located.

[0233] 9) Based on 8), the above three features correspond to different terminal capabilities, namely, whether the terminal supports CSI early triggering, CSI-RS early triggering, and SRS early triggering, respectively. 10) Based on 1) or 8), unlike the method described in 3), the terminal only needs to receive the SCell dormancy indication field in the first information, i.e., measure the CSI-RS of the SCell corresponding to the active BWP as a non-dormant BWP and / or send a CSI report, without needing any additional indication in the DCI, such as the CSI request field. The specific CSI-RS resource or resource set configuration information is determined based on RRC. For example, RRC may configure a default set of CSI-RS resource or resource set specifically for when the SCell dormancy state is exiting, as well as the corresponding CSI report configuration; or RRC may configure multiple sets of CSI report configurations and / or multiple sets of CSI-RS resource or resource sets, with the set with the smallest setID by default being the CSI report and CSI-RS resource or resource set configuration when the SCell dormancy state is exiting.

[0234] a) Specifically, furthermore, whether the terminal triggers CSI-RS reception and / or CSI report transmission after receiving the first information can be configured based on the RRC signaling of the network device. If the terminal supports three of the above first features, the network device can configure, based on RRC signaling, whether the terminal triggers the first information, and which one or more of them are triggered when triggered.

[0235] This disclosure proposes a communication method that triggers CSI-RS reception and / or CSI reporting simultaneously with the SCell dormancy indicator's expiration, enabling the terminal to transmit data with the SCell as quickly as possible based on accurate CSI after the SCell has exited dormancy, thereby improving throughput.

[0236] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0237] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods.

Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
