Transmission method, device, terminal and network equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311164935.9 filed in China on September 11, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of wireless technology, and in particular to a transmission method, apparatus, terminal, and network equipment. Background Art

[0004] The Long Term Evolution (LTE) system introduces carrier aggregation technology, which allows a terminal (such as user equipment (UE)) to connect to the network through multiple cells (cells), one of which is the primary cell (PCell) and the others are secondary cells (SCells). The SCell (or secondary carrier) in the carrier aggregation is activated upon receiving an activation command.

[0005] The activation time of a cell refers to the time between the terminal receiving the activation command and the terminal sending the Channel State Information (CSI) report. During this activation time, it is usually necessary to perform processes such as Hybrid Automatic Repeat Request (HARQ) feedback, Automatic Gain Control (AGC), synchronization, Layer 1 measurement and reporting. Therefore, there are many links that need to be executed within the cell activation time, and the duration of each link may be long, resulting in a long cell activation delay, which in turn causes the cell activation to fail to be completed in time, affecting system performance.

[0148] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0149] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0150] The activation time of the secondary cell in the related technology (or described as the activation delay of the secondary cell) is long, especially the activation of the unknown secondary cell in frequency range 2 (FR2), which includes more links, and the duration of each link may be long (taking FR2 as an example, the activation time of the unknown secondary cell in FR2 includes automatic gain control (AGC), cell search (or cell detection), synchronization, layer 1 measurement and other links, so the cell activation time is the superposition of these links, and because beam scanning is required (beam factor is 8), the time involved in the beam scanning will be longer (extended 8 times), and can even reach seconds, resulting in a longer cell activation time, which in turn leads to the inability to complete the cell activation in time, affecting system performance.

[0151] If the terminal has measured the cell before receiving the secondary cell activation command, the secondary cell activation steps can be shortened. However, if the terminal has only measured the cell before receiving the secondary cell activation command and has not reported the measurement results to the network (for example, due to lack of resources), the network will not be able to know that the terminal has measured the cell. The network will still assume that the terminal requires a longer secondary cell activation time, that is, it cannot or will not schedule the terminal within this period.

[0152] Based on the above problems, an embodiment of the present disclosure provides a transmission method, in which the terminal sends a first report to the network after the cell activation command, and indicates to the network through the first report that the terminal has recently measured the corresponding cell / frequency point, so as to reduce the link of secondary cell activation and achieve the effect of reducing delay; and / or, the terminal can also send a first message to the network, and indicate to the network through the first message the first information related to the beam, which can assist the network and the terminal to have a consistent understanding of the beam scanning, so that the terminal can complete the beam scanning faster, thereby reducing the link of secondary cell activation and achieving the effect of reducing delay; and / or, the terminal determines a first time related to the cell activation, and the determined first time is used to reduce the cell activation time, so as to reduce the link of secondary cell activation and achieve the effect of reducing delay.

[0153] In addition, reporting the measurement results after receiving the cell activation command can avoid the problem of being unable to report due to the channel quality not meeting the threshold or the lack of uplink resources. The measurement reporting of the related technology is performed only when the channel conditions (such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR)) meet a certain threshold (such as the RSRP of the serving cell is lower than the threshold, the RSRP quality of the neighboring cell is higher than the threshold, or the difference between the RSRP of the serving cell and the neighboring cell meets the threshold). If the above threshold is not met, the terminal does not perform measurement reporting. In addition, even if the threshold is met, if there are no uplink resources at the time of reporting, the terminal does not perform measurement reporting. In the method provided in the present disclosure, sending the first report after receiving the cell activation command can be free from the above factors. As long as the terminal has measurement results (or is described as having measured the target cell), the terminal can report the measurement results.

[0154] One embodiment of the present disclosure provides a transmission method, which is applied to a terminal. As shown in FIG1 , the method includes:

[0155] S110, after the cell activation command, sending a first report to the network; and / or

[0156] Sending first information to a network, wherein the first information is related to the beam; and / or

[0157] A first time is determined, where the first time is associated with cell activation.

[0158] It should be noted that, in the embodiments of the present disclosure, the network mentioned may also be referred to as a network side or a network side device. Optionally, the network side device may be a base station.

[0159] The sending of the first report to the network after the cell activation command may be a terminal that supports reporting of Layer 3 (L3) measurement results triggered by an unknown secondary cell activation command, and reports valid Layer 3 measurement results to the network after receiving the secondary cell activation command for an unknown secondary cell. That is, the first report may include the L3 measurement results.

[0160] Specifically, after receiving the secondary cell activation command, the terminal is ready to report the L3 result within a certain time (usually 7ms + the time between downlink data transmission and confirmation); or, the terminal is ready to report the L3 result no later than the predetermined time (or described as the first duration) after receiving the secondary cell activation command, and the predetermined time (or described as the first duration) is 7ms + the time between downlink data transmission and confirmation.

[0161] In some embodiments, the terminal reports first indication information, wherein the first indication information includes at least one of the following: an indication of whether layer 3 measurement result reporting triggered by an unknown secondary cell activation command is supported; an indication of whether a beam scanning factor reduction for secondary cell activation is supported; an indication of whether replacing the SMTC period with an SSB period in secondary cell activation is supported; and an indication of whether L1-RSRP measurement is supported in a non-DRX mode in secondary cell activation, even if DRX is configured. DRX refers to discontinuous reception (DRX).

[0162] The secondary cell activation time (or described as secondary cell activation delay) at least includes the time for obtaining the first available uplink resource for layer 3 reporting. The secondary cell activation time does not include the L1-RSRP measurement time (or described as measurement delay).

[0163] Optionally, in an embodiment of the present disclosure, “sending a first report to the network after the cell activation command” can also be described as “sending a first report after the cell activation command is triggered” or as “sending a first report to the network after receiving the cell activation command”.

[0164] Furthermore, in the embodiment of the present disclosure, the cell activation command mentioned may also be described as a secondary cell (SCell) activation command.

[0165] Optionally, the sending of the first report mentioned above can also be described as reporting the first report. Specifically, the first report can be carried by a MeasurementReport message. Optionally, the first information is related to the beam, and can also be described as the first information being related to beam scanning. Beam scanning can also be described as receiving beam scanning, and further can be described as the terminal receiving beam scanning. Optionally, considering that beam scanning affects activation delay, the first information is related to the beam and can also be described as the first information being related to cell activation delay. The first information includes at least a beam scanning factor for FR2 secondary cell activation, and / or the first information indicates whether the beam scanning factor for FR2 secondary cell activation is supported to be lowered or reduced. FR2 terminals can typically only receive signals in one direction at a time, so beam scanning is required to determine the optimal receiving beam. This process takes time, and the speed of beam scanning can be reflected by the beam scanning factor. The smaller the beam scanning factor, the less time the scanning takes. In related art, the beam scanning factor is 8. In the present disclosure, to reduce cell activation time, this can be achieved by introducing a smaller beam scanning factor. However, this approach imposes requirements on terminal cost and power consumption. The terminal must send a first message to inform the network whether it supports a beam scanning factor less than 8 and what the supported beam scanning factor is. This first message ensures that the network and the terminal have a consistent understanding of the terminal's beam scanning time.

[0166] Optionally, in step S110, the first report sent by the terminal to the network may include a secondary cell measurement report.

[0167] Using the transmission method described in the embodiment of the present disclosure, optionally, after the cell activation command, the terminal can send a secondary cell measurement report to the network on the resources of the Configuration Grant (CG). On the one hand, from the terminal's perspective, the cell is not completely new to the terminal, and the terminal has recently measured the cell / frequency point. One or more steps of performing the secondary cell activation AGC, cell search, synchronization, and layer 1 measurement (layer 1 measurement includes layer 1 reference signal received power (L1 Reference Signal Receiving Power, L1-RSRP) and / or layer 1 signal to interference plus noise ratio (L1 Signal to Interference plus Noise Ratio, L1-SINR)) can be reduced. On the other hand, from the network's perspective, the network also understands that the terminal has measured the cell based on the secondary cell measurement report sent by the terminal, thereby reducing the cell activation time, that is, the time that the terminal cannot be scheduled is also reduced. This solution can enable the terminal and the network to have a consistent understanding, thereby achieving the effect of reducing the secondary cell activation time.

[0168] Optionally, the first report includes at least one of the following:

[0169] Indication information indicating that there are measurement results;

[0170] Indicates that the measurement result is valid;

[0171] Indicates that the measurement result is invalid;

[0172] Indicates that there are no measurements.

[0173] Specifically, considering the channel conditions, the terminal may not have measured the cell, or even if it has measured, the signal quality is poor. By including the above information in the first report sent to the terminal, the network can be assisted in understanding the terminal's condition. If the first report indicates that there are no measurement results or the measurement results are not valid, then the cell detection, L1 measurement and other links in the secondary cell activation time cannot be omitted. In addition, the terminal may also send first information to the network, and the first information includes beam-related information. Optionally, the first information includes factors for the terminal to perform layer 1 measurement and / or factors for performing layer 3 measurement, and the specific values ​​are related to the terminal capabilities.

[0174] Optionally, the factor can also be described as a beam scanning factor. Compared to the beam scanning factor of 8 in the related art, the beam factor included in the first information can be less than 8. Because the scanning factor affects the measurement time (or is described as the measurement time being the product of the scanning factor and a certain time), the first information can help the network and the terminal have a consistent understanding, that is, the terminal can complete beam scanning more quickly, so that the time for related links of secondary cell activation (such as L3 measurement or described as cell search) and layer 1 measurement can be reduced, thereby reducing the FR2 secondary cell activation time.

[0175] In one embodiment, the terminal may optionally further determine a first time associated with cell activation, where the first time includes at least the cell activation time (the cell activation time may also be described as a cell activation delay). Compared to related technologies, the first time is shorter, thereby reducing the cell activation time.

[0176] In one embodiment, optionally, when the terminal does not send the first report or the first information, the first time can be determined through information predefined by the protocol (for example, a receiving beam scanning factor), and the predefined information includes at least a smaller factor (the value of the factor is less than 8), thereby reducing the cell activation time.

[0177] In one embodiment, optionally, the terminal sends first information to the network, and the first information at least includes received beam scanning information, such as a beam scanning factor. By reporting a smaller beam scanning factor supported by the first information (for example, the value of the factor is less than 8), the cell activation time is reduced.

[0178] Optionally, the cell activation time may be reduced by reducing steps in the cell activation time, such as reducing the processing time of one of the processing steps in the cell activation process, or setting the processing time to 0.

[0179] It should be noted that in the embodiments of the present disclosure, for the first solution: after the cell activation command, a first report is sent to the network; the second solution is to send the first information related to the beam to the network; the third solution is to determine the first time related to the cell activation. One of the three solutions can be executed, or any two or three can be executed in combination. Among them, the role of sending the first report is to enable at least part of the links in the secondary cell activation time to be omitted, the role of sending the first information is to reduce the time of the links involving beam scanning, and the role of determining the first time is to determine the first time based on the enhanced schemes such as the omission of some links brought about by the sending of the first report, the smaller beam scanning factor brought about by the sending of the first information and the pre-defined method of the protocol. The first time at least includes the cell activation time (the cell activation time can also be described as the cell activation delay). Compared with the related technology, the first time is shorter, thereby reducing the cell activation time.

[0180] Therefore, the above three methods can all reduce the activation time of the FR2 secondary cell (including the FR2 unknown secondary cell).

[0181] In the embodiment of the present disclosure, optionally, the measurement report mentioned is also described as any one of a measurement result, a layer 3 (L3) measurement result, and a layer 3 measurement report.

[0182] Optionally, the secondary cell mentioned includes an unknown secondary cell, and the unknown secondary cell includes an unknown secondary cell in frequency range 2 (FR2) and an unknown secondary cell in frequency range 1 (FR1). An unknown secondary cell generally means that the target secondary cell is unknown.

[0183] In an embodiment of the present disclosure, optionally, the first report includes one or more of a measurement result, a beam index, and a cell index.

[0184] Optionally, the measurement results include one or more of synchronization signal reference signal received power (SS-RSRP), synchronization signal reference signal received quality (SS-RSRQ), synchronization signal (SS) signal to interference plus noise ratio SS-SINR, channel state information reference signal received power (CSI-RSRP), channel state information reference signal received quality CSI-RSRQ, CSI signal to interference plus noise ratio CSI-SINR, L1-RSRP and L1-SINR.

[0185] Optionally, the beam index includes one or more of a measurement synchronization signal block (SSB) index and a CSI-RS index.

[0186] For example, the first report sent by the terminal to the network includes an SSB index, indicating that the terminal has measured the SSB corresponding to the SSB index; and includes layer 3 measurement information, indicating the measurement result information measured by the terminal on the SSB corresponding to the SSB index.

[0187] Optionally, the cell index may also be described as a secondary cell index or SCellIndex.

[0188] In one embodiment of the present disclosure, optionally, the measurement result is valid if the following conditions are met:

[0189] Deactivate the measurement period of the cell, and / or

[0190] Accuracy requirements.

[0191] The measurement period may also be described as measurement time or measurement period.

[0192] Optionally, when the measurement result is valid, that is, when the measurement period of the deactivated cell is met and / or when the accuracy requirement is met, the terminal sends the first report to the network, which can improve the quality of the measurement result in the first report and facilitate the network to apply the measurement result. If the measurement result does not meet the validity condition, the terminal does not report the measurement result. In the embodiment of the present disclosure, optionally, the method further includes:

[0193] receiving second information sent by the network;

[0194] The second information is used to instruct the terminal to send the first report after receiving the cell activation command; or, the second information is used to instruct the terminal not to send the first report after receiving the cell activation command; or, the second information is used to trigger the terminal to send the first report.

[0195] Using this implementation, the network sends second information to the terminal, indicating whether the terminal needs to send the first report after receiving the cell activation command, or the second information is used to trigger the terminal to send the first report, so that the terminal can send a measurement report to the network after receiving the cell activation command sent by the network according to the second information, if the measurement information of the target cell or target frequency is currently stored. In this way, through information interaction between the network and the terminal, the terminal reports the measurement information of the target cell or target frequency to the network, avoiding re-execution of AGC, synchronization and layer 1 measurement operations in the secondary cell activation process, thereby achieving the effect of reducing latency.

[0196] In the embodiment of the present disclosure, optionally, receiving the second information sent by the network includes one of the following:

[0197] receiving a cell activation command sent by a network, where the cell activation command is the second information;

[0198] receiving a cell activation command sent by a network, where the cell activation command includes the second information;

[0199] A first command is received, which is sent by the network before or after sending the cell activation command, where the first command includes the second information.

[0200] Optionally, the first command includes one or more of a medium access control (MAC) control element (CE) instruction, a radio resource control (RRC) signaling, and a downlink control information (DCI) signaling.

[0201] In an embodiment of the present disclosure, optionally, when the second information indicates that the terminal needs to send a first report, after the terminal receives the cell activation command sent by the network, it measures the activated secondary cell within a preset time range, or the terminal stores the measurement results of the activated secondary cell, and sends a measurement report to the network.

[0202] In one implementation manner, optionally, when the cell activation command is the second information, the cell activation command is used to instruct the terminal to send a measurement report after receiving the cell activation command.

[0203] In this embodiment, the second information is integrated into the cell activation command and implicitly sent to the terminal. Specifically, the cell activation command sent by the network to the terminal also implicitly indicates the second information. Optionally, the cell activation command instructs the terminal to send a measurement report after receiving the cell activation command. In this embodiment, after receiving the cell activation command, if the terminal has measured the target cell or target frequency within a preset time, it sends a measurement report to the network.

[0204] In one embodiment, optionally, when the cell activation command includes the second information, the preset bit in the cell activation command is used to indicate the second information, and when the second information is a first value, it is used to indicate that the terminal needs to send the first report; and / or when the second information is a second value, it is used to indicate that the terminal does not need to send the first report.

[0205] In this embodiment, the second information is integrated into the cell activation command and sent to the terminal in an explicit manner. Specifically, the cell activation command sent by the network to the terminal includes the second information, which is used to indicate whether the terminal needs to send a measurement report.

[0206] Optionally, the cell activation command is a MAC CE instruction. Optionally, the preset bit in the cell activation command is used to indicate the second information, and when the second information is a first value, it is used to indicate that the terminal needs to send a measurement report; when the second information is a second value, it is used to indicate that the terminal does not need to send a measurement report. For example, the preset bit is 1 bit. In the cell activation command, the preset bit is used to indicate to the terminal whether a measurement report needs to be sent, that is, the preset bit is used to indicate to the terminal whether to send a measurement report or not. If the preset bit is 1, it is used to indicate that the terminal needs to send a measurement report. If the preset bit is 0, it is used to indicate that the terminal does not need to send a measurement report.

[0207] Using this implementation method, the terminal needs to send a measurement report based on the second information sent by the network through the cell activation command (MAC CE instruction). When the second information indicates that the terminal needs to send a measurement report, all secondary cells corresponding to the cell activation command need to send a measurement report, that is, the terminal needs to send a measurement report for the activated secondary cells indicated in the cell activation command.

[0208] In another embodiment, optionally, when the cell activation command includes the second information, N bits in the cell activation command are used to indicate the second information, where each bit corresponds to a cell index, and is used to indicate whether the cell corresponding to the cell index needs to send the first report; wherein N is an integer greater than or equal to 1.

[0209] Specifically, the activated secondary cells indicated in the cell activation command may be sorted according to a preset order, such as sorted from largest to smallest according to the secondary cell index, or sorted from smallest to largest according to the secondary cell index. Each of the N bits corresponding to the second information corresponds to a secondary cell index and is used to indicate whether a measurement report needs to be sent for the secondary cell corresponding to the secondary cell index. For example, when one of the bits has a first value, it is used to indicate that the terminal needs to send a measurement report to the network device for the secondary cell corresponding to the bit; when the bit has a second value, it is used to indicate that the terminal does not need to send a measurement report to the network device for the secondary cell corresponding to the bit.

[0210] The cell activation command sent by the network device to the terminal includes second information, and the second information is used to display another implementation method of indicating whether the terminal needs to send a measurement report. When the cell activation command includes the second information, the cell activation command includes a cell index and a preset bit corresponding to the cell index, and the preset bit is used to indicate the second information, and the second information is used to indicate that the cell corresponding to the cell index needs to send the first report or does not need to send the first report.

[0211] Using this indication method, the secondary cell index of each secondary cell activated in the cell activation command corresponds to a preset bit. When the preset bit is a first value, it is used to indicate that the terminal needs to send a measurement report to the network device for the secondary cell; when the preset bit is a second value, it is used to indicate that the terminal does not need to send a measurement report to the network device for the secondary cell.

[0212] In another embodiment, optionally, when the first command includes the second information, the second information includes the cell index for sending the first report and / or first report sending indication information.

[0213] The first command includes one or more of MAC CE instructions, RRC signaling and DCI signaling.

[0214] When the first command includes a MAC CE instruction, optionally, the MAC CE instruction is an instruction different from the cell activation command and is specifically used to send the second information. In addition, in this embodiment, the second information in the MAC CE instruction is used to instruct the terminal to send a measurement report, or to instruct the terminal not to send a measurement report.

[0215] Optionally, the MAC CE instruction for sending the second information is sent after sending the cell activation command. In this way, after receiving the cell activation command, the terminal determines whether to send the measurement report to the network device according to the received MAC CE instruction.

[0216] Optionally, the MAC CE instruction for sending the second information is sent before sending the cell activation command, so that the terminal obtains the second information before receiving the cell activation command, and can send a measurement report to the network device after receiving the cell activation command. Compared with obtaining the second information after receiving the cell activation command, it can more effectively reduce the cell activation delay.

[0217] Optionally, in this embodiment, the second information includes the secondary cell index for which a measurement report needs to be sent and / or measurement report sending indication information, so that the measurement report sending indication information indicates whether the terminal needs to send a measurement report, and the secondary cell index indicates whether the secondary cell corresponding to the secondary cell index needs to send a measurement report.

[0218] In the embodiment of the present disclosure, optionally, the method further includes:

[0219] Sending third information and / or fourth information to the network; wherein the third information includes one or more of the following:

[0220] The terminal supports reducing activation time of a secondary cell;

[0221] The terminal performs a reduction in activation time of a secondary cell;

[0222] The fourth information includes one or more of the following:

[0223] Information indicating that the terminal has measurement results;

[0224] Cell ID.

[0225] It should be noted that, in the embodiments of the present disclosure, the reduction of the secondary cell activation time mentioned above may also be described as an enhancement of the secondary cell activation time.

[0226] By sending the third information to the network, the terminal notifies the network that it can support reducing the cell activation delay, or the terminal executes reducing the cell activation delay, that is, the terminal no longer re-performs operations such as AGG, synchronization, and L1 measurement required for cell activation.

[0227] In another implementation manner, optionally, the third information may also inform the network that the cell activation delay cannot be reduced, that is, the terminal needs to perform operations such as AGG, synchronization, and L1 measurement according to the normal cell activation process.

[0228] It should be noted that the cell activation process affects network scheduling. Whether the terminal can send measurement reports means whether the terminal can reduce the activation delay of the secondary cell. The network's knowledge of whether the terminal can reduce the cell activation delay helps the network perform scheduling. Whether the terminal can send measurement reports depends on whether the terminal supports secondary cell activation enhancement, whether the terminal has measured the cell in the recent period (for example, within 5 seconds) (i.e., whether there are measurement results). If the terminal sends a measurement report within a period of time (for example, 5 seconds), the cell is generally considered known; otherwise, the cell is considered unknown.

[0229] In an embodiment of the present disclosure, the terminal sends fourth information to the network, indicating that the terminal has stored measurement information for the target cell corresponding to the cell identifier. Optionally, the cell identifier included in the fourth information may be a cell index, and the information indicating that the terminal has a measurement result indicates that the terminal has a measurement result corresponding to the cell index.

[0230] In another implementation manner, optionally, the fourth information may also indicate that the terminal does not store the measurement information of the target cell. For example, the fourth information includes the cell index of the target cell and indication information corresponding to the cell index that does not include measurement information.

[0231] Since the cell activation process affects network scheduling, whether the terminal can send a measurement report means whether the terminal can reduce the cell activation delay. In this way, the network device can facilitate network scheduling by knowing whether the terminal can reduce the cell activation delay.

[0232] In the embodiment of the present disclosure, optionally, sending the first report to the network includes:

[0233] Sending a first report to the network when a first condition is met; the first condition includes one or more of the following:

[0234] measurements performed within a first time range before receiving a cell activation command;

[0235] measurements performed within a second time range after receiving a cell activation command;

[0236] Measurements performed within a third time range before sending a channel state information (CSI) report;

[0237] The measurement meets the accuracy requirements;

[0238] The measurement satisfies the measurement period.

[0239] Specifically, if the terminal stores measurement results of the target cell or target frequency, the terminal needs to determine the validity of the measurement results before sending the measurement report. Specifically, if the measurement results are obtained within a first time range before the cell activation command and / or within a second time range after the cell activation command and / or within a third time range before reporting the CSI report, the measurement information is determined to be valid, and the step of sending the measurement report to the network device is performed.

[0240] Optionally, the first time range, the second time range and the third time range may be configured by the network or predefined by a protocol.

[0241] This implementation ensures that the measurement results in the first report are valid, ensuring that they are valid. If the measurement results stored by the terminal are from a long time ago, given channel variations, they are likely invalid and no longer represent the actual channel conditions. The terminal will need to redo the cell search and measurement process, which is essential for secondary cell activation. If the measurement results are not valid, the terminal does not need to send the first report. If the measurement results are from a recent measurement, validity is guaranteed, and the cell search and measurement process can be omitted during secondary cell activation.

[0242] Optionally, when it is determined according to the above method that the measurement information for measurement is invalid, the terminal may send fifth information to the network device to report to the network device that the measurement result will not be reported, that is, the cell activation delay reduction process will not be performed; or send sixth information to the network device to indicate to the network device that the terminal does not store measurement information of the target cell or target frequency. Optionally, the sent sixth information includes an identifier of the target cell or target frequency for which no measurement information is available.

[0243] In the embodiment of the present disclosure, optionally, the first information includes one or more of the following information:

[0244] The terminal supports factors less than 8;

[0245] The terminal supports a factor less than 8 for cell detection;

[0246] The terminal supports a factor less than 8 for L1 measurements;

[0247] A first value, which is a value of a factor used for cell detection;

[0248] The second value is the value of the factor used for L1 measurement.

[0249] It should be noted that in the embodiments of the present disclosure, "the terminal supports a factor less than 8" can also be described as the terminal supporting a beam scanning factor less than 8, including in an FR2 unknown secondary cell scenario, where the terminal supports a beam scanning factor less than 8. "The terminal supports a factor less than 8 for cell detection" can also be described as the terminal supporting a beam scanning factor less than 8 for cell detection (or described as cell search, or described as Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS) detection), including in an FR2 unknown secondary cell scenario, where the terminal supports a beam scanning factor less than 8 for cell detection. "The terminal supports a factor less than 8 for L1 measurement" can also be described as the terminal supporting a beam scanning factor less than 8 for L1 measurement, including in an FR2 unknown secondary cell scenario, where the terminal supports a beam scanning factor less than 8 for L1 measurement. The first value can be understood as the beam scanning factor for cell detection in an FR2 unknown secondary cell scenario. The second value can be understood as the beam scanning factor for L1 measurement in an FR2 unknown secondary cell scenario.

[0250] Optionally, the set of first values ​​is {1, 2, 4, 6}, where "the first value is the value of the factor used for cell detection" can be understood as the block measurement timing configuration (SSB-based Measurement Timing configuration, SMTC) multiplied by the first value or the SSB period multiplied by the first value. "The first value is the value of the factor used for cell detection" can also be described as the first value indicating a reduced beam scanning factor for cell detection; or as the first value indicating a reduced beam scanning factor for cell detection; it can also be described as the first value indicating a reduced beam scanning factor for cell detection when the terminal has a full set of beam scanning (which can be understood as a beam scanning factor equal to 8) during the AGC determination process.

[0251] Optionally, the set of second values ​​is {0, 1, 2, 3, 4, 5, 6, 7}, where "the second value is the value of the factor used for L1 measurement" can be understood as the L1-RSRP measurement time at least including the SSB period multiplied by the second value or the CSI-RS period multiplied by the second value. "The second value is the value of the factor used for L1 measurement" can also be described as the second value indicating a reduced beam scanning factor for L1 measurement; or as the second value indicating a reduced beam scanning factor for L1 measurement; or as the second value indicating a reduced beam scanning factor for L1-RSRP measurement; and can also be described as the second value indicating a reduced beam scanning factor for L1-RSRP measurement when the terminal has a full set of beam scanning (which can be understood as the beam scanning factor equal to 8) during the AGC determination process.

[0252] Optionally, the method further includes:

[0253] The secondary cell activation time of the terminal at least includes: 3 ms and / or the time between an activation command and a transmission configuration indicator (TCI) command.

[0254] It should be noted that after the secondary cell activation is enhanced, the reduced cell activation delay includes MAC CE time (or described as MAC CE decoding / processing time), the delay in sending measurement reports, the L1 measurement delay (L1-RSRP, L1-SINR), and the margin (for example, the time between the cell activation command and the TCI command, or the time between sending the measurement report and the TCI command). The TCI command is optionally a TCI activation command or a TCI configuration command. In other words, steps such as cell detection and L1 measurement can be omitted.

[0255] Optionally, the cell activation delay includes one of the following:

[0256] The cell activation delay at least includes the MAC CE feedback time (e.g., 3ms);

[0257] The cell activation delay includes at least the AGC time (AGC time can be described as TFirstSSB_MAX+15*TSMTC_MAX, where TFirstSSB_MAX is the time of the first complete SSB burst indicated by SMTC, and TSMTC_MAX is the longer SMTC period between the activated serving cell and the secondary cell being activated);

[0258] The cell activation delay includes at least 3ms + the time between the activation command and the TCI command;

[0259] The cell activation delay includes at least 3ms + the time between the activation command and the TCI command + the L1 measurement time;

[0260] The cell activation delay includes at least 3ms + the delay of sending the measurement report + the time between the activation command and the TCI command;

[0261] The cell activation delay includes at least 3ms + the delay for sending the measurement report + the time between the activation command and the TCI command + the L1 measurement time. Optionally, the method further includes:

[0262] The secondary cell activation time (also described as a secondary cell activation delay) of the terminal includes at least one of the following:

[0263] The factor, the first value, or the second value is multiplied by a synchronization signal physical broadcast channel (SS / PBCH) block measurement timing configuration (SSB-based Measurement Timing configuration, SMTC);

[0264] The factor, the first value, or the second value multiplied by the period of the synchronization signal physical broadcast channel SS / PBCH block SSB;

[0265] The factor, the first value, or the second value is multiplied by N; wherein the value of N is 1 or 3.

[0266] In the embodiment of the present disclosure, optionally, the synchronization signal physical broadcast channel SS / PBCH block can also be described as a synchronization signal block SSB.

[0267] Optionally, the SMTC includes the SMTC period of the secondary cell being activated.

[0268] In one embodiment, since the period of SSB is generally not greater than SMTC, the secondary cell activation time of the terminal is the factor, the first value, or the second value multiplied by the period of the synchronization signal physical broadcast channel SS / PBCH block SSB, compared to the secondary cell activation time of the terminal being the factor, the first value, or the second value multiplied by SMTC, the secondary cell activation time can be further reduced. Optionally, the factors mentioned include but are not limited to only including beam scanning factors. The first factor and the second factor include one or more of the beam scanning factors supported by the terminal, the beam scanning factors supported for cell detection, and / or the beam scanning factors supported for L1 measurement.

[0269] Specifically, since the beam scanning factor affects the measurement time (the measurement time is the product of the scanning factor and a certain time), the first information can assist the network and the terminal to have a consistent understanding, that is, the terminal can complete the beam scanning faster, and the time of related links (such as L3 measurement or described as cell search, or described as cell detection), layer 1 measurement, etc. can be reduced, thereby realizing the FR2 secondary cell activation time.

[0270] Optionally, both the first value and the second value are less than 8. Specifically, if the beam scanning factor used by the terminal in the AGC link is 8, it means that the terminal has obtained certain beam information, then in the subsequent cell detection and L1 measurement links, corresponding beam scanning simplification (or enhancement) can be performed. The specific simplification depends on the terminal implementation, so the terminal needs to report the first value and the second value.

[0271] In the embodiment of the present disclosure, optionally, sending a first report to the network includes:

[0272] The terminal sends a first report to the network within a first time after receiving the cell activation command; or

[0273] The terminal sends a first report to the network within a second time after receiving the second information.

[0274] The terminal does not send the first report to the network if a first time has passed after receiving the cell activation command, and does not send the first report to the network if a second time has passed after receiving the second message. This allows the terminal to send the first report as soon as possible after receiving the secondary cell activation command. Furthermore, it enables the network to determine how to allocate uplink resources to the terminal for sending the report. If the first report is not sent, steps such as cell detection and L1 measurement during the secondary cell activation period cannot be omitted.

[0275] In addition, with this implementation, a first report is sent to the network within the first time after receiving the cell activation command, or a first report is sent to the network within the second time after receiving the second information. By introducing the first time and the second time, the terminal can avoid indefinitely searching for resources for sending the first report. Optionally, if the terminal does not find resources within the first time or the second time, the terminal may not send the first report. The values ​​of the first time and the second time can be configured by the network or predefined in the protocol. The lengths of the first time and the second time include at least one of the HARQ time, the MAC CE processing time (also described as 3ms), and the time margin. In one embodiment of the present disclosure, when the terminal determines the first time, the determined first time includes at least one of the following:

[0276] 3ms;

[0277] 6ms;

[0278] The time between the activation command and the transmission configuration indication TCI command;

[0279] SMTC multiplied by A, where A is an integer less than 8;

[0280] The SSB period is multiplied by B, where B is an integer less than 8;

[0281] C times N times SMTC;

[0282] C times N times the SSB period;

[0283] C times N times the CSI-RS period;

[0284] Wherein, the value of N is 1 or 3, and C is an integer less than 8.

[0285] In this embodiment, optionally, A, B and C can be one or more of the following:

[0286] The terminal supports factors less than 8;

[0287] The terminal supports a factor less than 8 for cell detection;

[0288] The terminal supports a factor less than 8 for L1 measurements;

[0289] A first value, which is a value of a factor used for cell detection;

[0290] The second value is the value of the factor used for L1 measurement.

[0291] By adopting this implementation, compared with the related technology, the first time determined according to the pre-defined protocol is reduced, that is, the time related to cell activation is reduced, so that the processing time of one of the processing processes in the cell activation process can be reduced, thereby achieving the effect of reducing the cell activation time. With the cell activation method described in the embodiment of the present disclosure, after the terminal receives the second information sent by the network, if the second information indicates that the terminal needs to send a measurement report, after receiving the cell activation command sent by the network, the terminal sends the measurement report to the network. In addition, according to the cell activation command, the terminal no longer needs to re-perform operations such as AGG, synchronization, and L1 measurement required for cell activation, but only needs to perform HARQ feedback and CSI report reporting. In this way, the cell activation delay can only include the time for HARQ feedback (such as 3ms), thereby greatly reducing the cell activation delay. In addition, for FR2, the cell activation delay is the sum of the time for HARQ feedback (such as 3ms) and the time between the cell activation command sent by the network and the transmission configuration indicator (TCI) command of the beam. Since the time for AGG, synchronization, and L1 measurement does not need to be included, the cell activation delay can also be greatly reduced.

[0292] One embodiment of the present disclosure further provides a transmission method, which is performed by a network device, as shown in FIG2 , and includes:

[0293] S210, receiving a first report sent by a terminal after a cell activation command and / or receiving first information sent by a terminal; wherein the first information is related to a beam.

[0294] By adopting the transmission method described in the embodiment of the present disclosure, the terminal sends a first report and / or first information to the network after the cell activation command, and indicates to the network through the first report that the terminal has recently measured the corresponding cell / frequency point, so as to reduce the link of secondary cell activation and achieve the effect of reducing latency; indicating the first information related to the beam to the network through the first information can assist the network and the terminal to have a consistent understanding of the beam scanning, so that the terminal can complete the beam scanning faster, thereby reducing the link of secondary cell activation and achieving the effect of reducing latency.
