[0002] In a wireless communication network, the network side may configure multiple serving cells for a terminal. The serving cells may include a primary cell PCell (Primary Cell), a primary secondary cell PSCell (Primary Secondary Cell) and other serving cells, which may also be referred to as secondary cells SCell.

[0003] In related technologies, in order to speed up the activation / deactivation process of SCell, a temporary reference signal temporary RS is introduced. However, based on the temporary RS, only part of the activation / deactivation process of SCell can be accelerated, and the effect of accelerating the activation / deactivation of SCell is not ideal. Summary of the invention

[0005] According to a first aspect of an embodiment of the present disclosure, a channel state information sending method is proposed, which is executed by a terminal, and the method includes: determining a time domain resource range of a channel state information reference signal SAS-CSI RS dedicated to activation of a secondary cell; receiving the SAS-CSI RS according to the time domain resource range; generating valid channel state information valid CSI according to the SAS-CSI RS and sending it to a network side device.

[0006] According to a second aspect of an embodiment of the present disclosure, a reference signal sending method is proposed, which is executed by a network side device. The method includes: determining a time domain resource range of a channel state information reference signal SAS-CSI RS dedicated to activation of a secondary cell; and sending the SAS-CSI RS according to the time domain resource range.

[0007] According to a third aspect of an embodiment of the present disclosure, a channel state information sending device is proposed, comprising one or more processors, wherein the processors are configured to execute: determining a time domain resource range of a channel state information reference signal SAS-CSI RS dedicated to activation of a secondary cell; receiving the SAS-CSI RS according to the time domain resource range; generating valid channel state information valid CSI according to the SAS-CSIRS and sending it to a network side device.

[0008] According to a fourth aspect of an embodiment of the present disclosure, a reference signal sending device is proposed, comprising one or more processors, wherein the processors are configured to execute: determining a time domain resource range of a channel state information reference signal SAS-CSIRS dedicated to secondary cell activation; and sending the SAS-CSI RS according to the time domain resource range.

[0009] According to a fifth aspect of an embodiment of the present disclosure, a communication device is proposed, comprising: a processor; and a memory for storing a computer program; wherein, when the computer program is executed by the processor, the above-mentioned channel state information sending method is implemented.

[0010] According to a sixth aspect of an embodiment of the present disclosure, a communication device is proposed, comprising: a processor; and a memory for storing a computer program; wherein, when the computer program is executed by the processor, the above-mentioned reference signal sending method is implemented.

[0011] According to a seventh aspect of an embodiment of the present disclosure, a computer-readable storage medium is proposed for storing a computer program.

[0012] According to an eighth aspect of an embodiment of the present disclosure, a computer-readable storage medium is proposed for storing a computer program. When the computer program is executed by a processor, the steps in the above-mentioned reference signal sending method are implemented.

[0013] According to an embodiment of the present disclosure, the network side device does not continuously send the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation, but only sends the SAS-CSI RS within the time domain resource range. Accordingly, the terminal only needs to receive the SAS-CSI RS within the time domain resource range.

[0014] Accordingly, even if the period of SAS-CSI RS is set relatively small, since the network side device only sends SAS-CSI RS within the time domain resource range, and does not send SAS-CSI RS outside the time domain resource range, the impact on the network side device overhead is small, and the terminal accordingly only receives SAS-CSI RS within the time domain resource range, and does not receive SAS-CSI RS outside the time domain resource range. This is conducive to ensuring that the period of SAS-CSI RS is shortened without significantly increasing network overhead, so that the terminal can receive SAS-CSI RS faster, and then complete the reporting of valid CSI faster to complete the activation of the secondary cell.

[0031] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0035] Figure 1 It is a schematic diagram of the process of activating SCell in the related art.

[0036] like Figure 1 As shown in FIG. 1 , for a SCell in a deactivated state, the process of activating the SCell mainly includes three steps:

[0037] The network side carries the activation indication in the Media Access Control Control Element (MAC CE) sent to the terminal, for example, the MAC CE is carried by the Physical Downlink Shared CHannel (PDSCH) of the PCell. After receiving the MAC CE, the terminal returns the Hybrid Automatic Repeat reQuest (HARQ) information to the network side device, for example, returns the HARQ-ACK to indicate to the network side that the terminal has received the MAC CE. This stage is called HARQ timing.

[0038] Next, after receiving the MAC CE, the terminal performs hardware preparation, which may further include multiple sub-steps. First, the MAC CE is parsed to determine the specific information carried therein, for example, it takes 3ms, and then waits for receiving the synchronization signal block SSB (Synchronization Signal Block), for example, the waiting time is T_firstSSB. After receiving the SSB, SSB-based time-frequency tracking is performed. This stage is called the activation time.

[0039] Finally, the terminal generates valid channel state information valid CSI based on the channel state information reference signal CSI RS (Channel State Information Reference Signal, generally referred to as P-CSI-RS) continuously sent by the network side to activate the SCell, and reports it to the network side. The network side determines the SCell activation based on the valid CSI; this stage is called CSI reporting.

[0040] In this process, the terminal needs to complete time-frequency tracking first, and then generate valid CSI for reporting based on the P-CSI-RS continuously sent by the network side. Time-frequency tracking is based on SSB, so it is necessary to receive SSB first. Figure 1 As shown, the reception of SSB is based on SMTC periodicity, that is, SSB measurement timing configuration (SSB MeasurementTiming Configuration) period, but this period is relatively long, which makes it difficult to complete time-frequency tracking in time. To address this problem, a temporary reference signal temporary RS is further proposed in the related art.

[0041] Figure 2 It is a schematic diagram of introducing a temporary reference signal in the process of activating an SCell in the related art.

[0042] like Figure 2As shown in the figure, the network side can send temporary RS periodically, and the period of temporary RS is smaller than SMTC periodicity. The terminal can be activated to receive temporary RS through MAC CE. Since the period of temporary RS is relatively small, the terminal can receive temporary RS faster than SSB after receiving MAC CE, and then perform automatic gain control setting AGC (Automatic Gain Control) settling and time-frequency tracking T / F tracking according to temporary RS, so as to achieve the desired effect. Figure 1 In this case, the time-frequency tracking can be completed faster, and the reporting of valid CSI can be completed faster, thus speeding up the process of activating SCell.

[0043] based on Figure 2 It can be seen that the process of activating SCell can be accelerated by introducing temporary RS, but after analysis, it is known that only part of the process of activating SCell is accelerated, specifically the part of activating SCell to complete time-frequency tracking. Since the terminal generates valid CSI reports based on the P-CSI-RS continuously sent by the network side, the part from completing time-frequency tracking to reporting valid CSI is not accelerated by the introduction of temporary RS.

[0044] In order to speed up the reporting of valid CSI, one of the main ways is to shorten the period of P-CSI-RS so that the terminal can generate valid CSI for reporting based on P-CSI-RS. Currently, the minimum period of P-CSI-RS is 4 time slots and the maximum period is 640 time slots. Since P-CSI-RS is continuously sent by the network side, shortening the period of P-CSI-RS will significantly increase network overhead. The embodiments of the present disclosure are mainly proposed to solve this technical problem.

[0045] Figure 3 It is a schematic flow chart of a method for sending channel state information according to an embodiment of the present disclosure. The method for sending channel state information shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc. The terminal can communicate with a network side device, and the network side device includes but is not limited to a network side device in a 4G, 5G, 6G, etc. communication system, such as a base station, a core network, etc.

[0046] like Figure 3 As shown, the channel state information sending method may include the following steps:

[0047] In step S301, a time domain resource range of a channel state information reference signal SAS-CSI RS dedicated to activation of a secondary cell is determined;

[0048] In step S302, the SAS-CSI RS is received according to the time domain resource range;

[0049] In step S303, valid channel state information valid CSI is generated according to the SAS-CSI RS and sent to a network side device.

[0050] In one embodiment, the network side device can send (for example, broadcast, unicast, or multicast) a channel state information reference signal SAS-CSI RS dedicated to secondary cell activation, which can be called SCell activation specific CSI RS. For the convenience of description, it is hereinafter referred to as SAS-CSI RS.

[0051] The network side device and the terminal may respectively determine the time domain resource range of the SAS-CSI RS, for example, a time window, and the network side device may send the SAS-CSI RS within the determined time domain resource range, and may send the SAS-CSI RS within the determined time domain resource range according to the configuration information configured to the terminal.

[0052] The configuration information may include the period of the SAS-CSI RS, the number of periods (which can be understood as the number of transmissions), etc. For example, the period is N time slots, N is less than the period threshold M, and M can be set as needed. For example, M=10 can be set. Generally, the minimum value of N is 4, and the N value can be appropriately set to be relatively small so that the terminal can receive the SAS-CSI RS as soon as possible.

[0053] The terminal can receive SAS-CSI RS within a determined time domain resource range, for example, send SAS-CSI RS within a determined time domain resource range according to the configuration information configured by the network side device. After receiving the SAS-CSI RS, the terminal can generate valid CSI based on the SAS-CSI RS and send it to the network side device, and the network side device can determine whether the secondary cell SCell is activated based on the valid CSI.

[0054] According to an embodiment of the present disclosure, the network side device does not continuously send the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation, but only sends the SAS-CSI RS within the time domain resource range. Accordingly, the terminal only needs to receive the SAS-CSI RS within the time domain resource range.

[0055] Accordingly, even if the period of SAS-CSI RS is set relatively small, since the network side device only sends SAS-CSI RS within the time domain resource range, and does not send SAS-CSI RS outside the time domain resource range, the impact on the network side device overhead is small, and the terminal accordingly only receives SAS-CSI RS within the time domain resource range, and does not receive SAS-CSI RS outside the time domain resource range. This is conducive to ensuring that the period of SAS-CSI RS is shortened without significantly increasing network overhead, so that the terminal can receive SAS-CSI RS faster, and then complete the reporting of valid CSI faster to complete the activation of the secondary cell.

[0056] In one embodiment, the manner of determining the time domain resource range includes at least one of the following:

[0057] Determined according to the instruction information sent by the network side device;

[0058] Determined according to the agreement.

[0059] In one embodiment, the time domain resource range of the SAS-CSI RS can be determined according to the protocol agreement. In this case, both the network side device and the terminal can determine the time domain resource range of the SAS-CSI RS according to the protocol agreement, and then the network side device can send the SAS-CSI RS within the time domain resource range, and the terminal can receive the SAS-CSI RS within the time domain resource range.

[0060] In one embodiment, the time domain resource range of the SAS-CSI RS can be set by the network side device as needed, and then sent to the terminal through indication information. In this case, the network side device can independently determine the time domain resource range of the SAS-CSI RS, and then indicate the time domain resource range to the terminal through the indication information, so that the network side device can send the SAS-CSI RS within the time domain resource range, and the terminal can receive the SAS-CSI RS within the time domain resource range.

[0061] The indication information may be carried in a MAC CE, and the MAC CE carrying the indication information may reuse the same MAC CE as the MAC CE for activating the temporary RS, or other MAC CEs may be used to carry the indication information.

[0062] Figure 4A FIG. 1 is a schematic flow chart of another method for sending channel state information according to an embodiment of the present disclosure. Figure 4A As shown, the time domain resource range for determining the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes:

[0063] In step S401, a starting position of the time domain resource range is determined in the time domain resources after a temporary reference signal temporary RS is received.

[0064] In one embodiment, the network side device can determine the starting position of the time domain resource range in the time domain resources after sending the temporary RS based on the protocol agreement, and accordingly, the terminal can determine the starting position of the time domain resource range in the time domain resources after receiving the temporary RS based on the protocol agreement.

[0065] For example, the starting position can be determined according to the time slot where the temporary RS is located and an offset offset (greater than or equal to 0 time slots), for example, the starting position is the time slot where the temporary RS is located plus the offset, wherein the offset can be indicated by the network side device, or is also determined according to the protocol agreement.

[0066] In one embodiment, the network side device can be set as needed to determine the starting position of the time domain resource range in the time domain resources after sending the temporary RS, and then can send indication information to the terminal, instructing the terminal to determine the starting position of the time domain resource range in the time domain resources after receiving the temporary RS through the indication information.

[0067] For example, the starting position may be determined according to the time slot where the temporary RS is located and the offset, for example, the starting position is the time slot where the temporary RS is located plus the offset, wherein the offset may be determined according to a protocol agreement or may also be indicated by a network side device.

[0068] In one embodiment, since the network side device configures a temporary RS for the terminal and determines the need to report valid CSI as soon as possible only when the terminal is activated to receive the temporary RS, the starting position of the time domain resource range can be determined in the time domain resources after receiving the temporary RS, so that when the temporary RS is received and it is determined that there is a need to report valid CSI as soon as possible, the terminal starts to receive SAS-CSI RS from the starting position, and accordingly, the network side device can start to send SAS-CSI RS after sending the temporary RS. This is conducive to avoiding the waste of resources caused by the terminal receiving SAS-CSI RS and the network side sending SAS-CSI RS when there is no need to report valid CSI as soon as possible.

[0069] Figure 4Bis a schematic diagram of a SAS-CSI RS according to an embodiment of the present disclosure.

[0070] like Figure 4B As shown, the starting position of the time domain resource range is the time slot where the temporary RS is located plus the offset offset. The network side device periodically sends SAS-CSI RS, and the surrounding Periodicity can be configured as needed. The end position of the time domain resource range can be, for example, the time domain position where the valid CSI report is completed. When the offset is 0, the starting position can be the first time slot after the time slot where the temporary RS is located.

[0071] Figure 5A FIG. 1 is a schematic flow chart of another method for sending channel state information according to an embodiment of the present disclosure. Figure 5A As shown, the time domain resource range for determining the channel state information reference signal SAS-CSI RS dedicated to the activation of the secondary cell includes:

[0072] In step S501, the starting position of the time domain resource range is determined in the time domain resources after completing automatic gain control setting AGC settling and time frequency tracking T / F tracking.

[0073] In one embodiment, the terminal may determine the starting position of the time domain resource range in the time domain resources after completing AGC settling and T / F tracking according to a protocol agreement, or may determine the starting position of the time domain resource range in the time domain resources after completing AGC settling and T / F tracking according to an instruction of a network side device.

[0074] In this case, the terminal can determine the starting position of the time domain resource range in the time domain resources after completing AGC settling and T / F tracking, and then start receiving the SAS-CSI RS at the starting position. Since AGCsettling and T / F tracking are actions performed by the terminal, the network side device may not be able to determine when the terminal completes AGC settling and T / F tracking.

[0075] If the network side device cannot determine when the terminal completes AGC settling and T / F tracking, in order to ensure that the terminal can receive the SAS-CSI RS after completing AGC settling and T / F tracking, the starting position of sending the SAS-CSI RS determined by the network side device may be earlier than the starting position of receiving the SAS-CSI RS determined by the terminal.

[0076] For example, the starting position of sending SAS-CSI RS determined by the network side device may be the first time slot after sending temporary RS, or the time slot before sending temporary RS. Since the terminal needs to perform AGC settling and T / F tracking according to temporary RS, the network side device starts sending SAS-CSI RS in the first time slot after sending temporary RS, or in the time slot before sending temporary RS, which can ensure that the terminal can receive SAS-CSI RS at the time domain position after completing AGC settling and T / F tracking.

[0077] If the network side device can determine when the terminal completes AGC settling and T / F tracking, the network side device can choose to use the first time slot after the terminal completes AGC settling and T / F tracking as the starting position for sending SAS-CSI RS, or can choose to use the time slot before the terminal completes AGC settling and T / F tracking as the starting position for sending SAS-CSI RS. Accordingly, it can also ensure that the terminal can receive SAS-CSI RS in the time domain position after completing AGC settling and T / F tracking.

[0078] In one embodiment, before the terminal completes AGC settling and T / F tracking, there may be a certain degree of asynchrony between the network side and the terminal side, which leads to inconsistency in the understanding of the time domain resource range between the network side device and the terminal, which leads to subsequent problems. In order to avoid this situation, the terminal can determine the starting position of the time domain resource range in the time domain resources after completing AGC settling and T / F tracking, thereby ensuring that the SAS-CSI RS is received only after the AGC settling and T / F tracking are completed, and ensuring that the SAS-CSI RS is received when the network side device and the terminal have a consistent understanding of the time domain resource range.

[0079] Figure 5B is a schematic diagram of another SAS-CSI RS according to an embodiment of the present disclosure.

[0080] like Figure 5B As shown, for example, the network side device still uses the time slot where the temporary RS is located plus the offset as the starting position, that is, the sending starting position, and starts to send the SAS-CSI RS at the sending starting position; and after receiving the temporary RS, the terminal needs to complete AGC settling and T / F tracking first, and then determine the starting position of receiving the SAS-CSI RS, that is, the receiving starting position. The receiving starting position is after AGC settling and T / Ftracking, ensuring that the network side device and the terminal have the same understanding of the time domain resource range, and then the terminal starts to receive the SAS-CSI RS. In this case, the time domain resource range of the SAS-CSI RS determined by the network side device and the time domain resource range of the SAS-CSI RS determined by the terminal may be different.

[0081] In one embodiment, the method for determining the time domain resource range includes determining it according to the indication information of the network side device, and determining the time domain resource range of the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes: determining the starting position of the time domain resource range according to the absolute time position indicated by the indication information.

[0082] In the case where the network side device instructs the terminal to determine the time domain resource range through the indication information, the network side device may indicate the absolute time position as the starting position of the time domain resource range through the indication information.

[0083] In one embodiment, the method for determining the time domain resource range includes determining according to the indication information of the network side device, and determining the time domain resource range of the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes: determining the starting position of the time domain resource range according to the offset relative to the preset time domain position indicated by the indication information.

[0084] When the network side device instructs the terminal to determine the time domain resource range through indication information, the network side device can indicate the offset to the terminal, and the terminal can determine the starting position of the time domain resource range according to the preset time domain position and the offset indicated by the network side device.

[0085] The preset time domain position may be determined based on a protocol agreement, or may be pre-indicated by a network side device. In one embodiment, the preset time domain position includes at least one of the following:

[0086] The time domain position of the received temporary RS;

[0087] The time domain location of receiving the indication information;

[0088] The downlink time slot corresponding to the time domain position of the hybrid automatic repeat request HARQ corresponding to the indication information is sent.

[0089] Figure 6 FIG. 1 is a schematic flow chart of another method for sending channel state information according to an embodiment of the present disclosure. Figure 6 As shown, the time domain resource range for determining the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes:

[0090] In step S601, the time domain position for sending the valid CSI is determined to be the end position of the time domain resource range.

[0091] In one embodiment, since the terminal has completed the activation / deactivation process of the secondary cell after sending the valid CSI, the SAS-CSI RS is not received after sending the valid CSI (before the next time the secondary cell needs to be activated / deactivated). Therefore, the time domain position (e.g., time slot) for sending the valid CSI can be determined as the end position of the time domain resource range for receiving the SAS-CSI RS. After the end position, the terminal stops receiving the SAS-CSI RS.

[0092] Correspondingly, the network side device may determine the time domain position at which the valid CSI is received as the end position of the time domain resource range for sending the SAS-CSI RS, and after the end position, the network side device stops sending the SAS-CSI RS.

[0093] Figure 7 FIG. 1 is a schematic flow chart of another method for sending channel state information according to an embodiment of the present disclosure. Figure 7 As shown, the receiving the SAS-CSI RS according to the time domain resource range includes:

[0094] In step S701, when it is determined that the network side device has configured a temporary RS for the terminal and activated the terminal to receive the temporary RS, the SAS-CSI RS is received according to the time domain resource range.

[0095] In one embodiment, the method further comprises:

[0096] In step S702, when it is determined that the network side device has not activated the terminal to receive a temporary RS or has not configured a temporary RS for the terminal, the SAS-CSI RS is not received according to the time domain resource range.

[0097] In one embodiment, the network side device determines that there is a need to report the valid CSI as soon as possible only when the network side device configures the temporary RS for the terminal and activates the terminal to receive the temporary RS.

[0098] Therefore, the terminal can receive the SAS-CSI RS according to the time domain resource range only when it is determined that the network side device has configured a temporary RS for the terminal and activated the terminal to receive the temporary RS. However, when it is determined that the network side device has not activated the terminal to receive the temporary RS or has not configured the temporary RS for the terminal, the terminal does not receive the SAS-CSI RS according to the time domain resource range.

[0099] Correspondingly, the network side device may send the SAS-CSI RS according to the time domain resource range only when it is determined that the temporary RS is configured for the terminal and the terminal is activated to receive the temporary RS. However, when it is determined that the terminal is not activated to receive the temporary RS or the temporary RS is not configured for the terminal, the SAS-CSI RS is not sent according to the time domain resource range.

[0100] Accordingly, it is possible to avoid wasting resources due to the terminal receiving the SAS-CSI RS and the network side sending the SAS-CSI RS when there is no need to report the valid CSI as soon as possible.

[0101] In one embodiment, the method further includes: performing at least one of the following operations based on the SAS-CSI RS:

[0102] Using the SAS-CSI RS as a quasi co-location source QCL source of other RSs before receiving the preset RS;

[0103] Perform interference measurement according to the SAS-CSI RS;

[0104] Mobility management is performed according to the SAS-CSI RS.

[0105] In one embodiment, the SAS-CSI RS in the embodiment shown in the present disclosure may be different from the P-CSI-RS in the related art. On the one hand, the SAS-CSI RS is sent and received within the time domain resource range, while the P-CSI-RS is continuously sent. On the other hand, the period of the SAS-CSI RS may be shorter than that of the P-CSI-RS, so that the terminal can receive the SAS-CSI RS faster and generate valid CSI to complete the reporting accordingly.

[0106] When the period of SAS-CSI RS is shorter than that of P-CSI-RS, the terminal generally receives SAS-CSI RS faster. Then, for other RS ​​before the preset RS, such as other RS ​​before P-CSI-RS, SAS-CSI RS can be used as the QCL source of other RS, which is conducive to faster determination of the QCL source of other RS.

[0107] For example, other RSs may include a demodulation reference signal (DMRS), where the DMRS is a DMRS within W time slots after the terminal activates the secondary cell, where W is an integer greater than or equal to 1 and can be set as needed, for example, the terminal does not receive a P-CSI-RS within W time slots after activating the secondary cell.

[0108] In addition, other functions can be implemented based on the SAS-CSI RS, such as interference measurement based on the SAS-CSI RS, mobility management based on the SAS-CSI RS (for example, judging whether to switch cells based on the reception quality of the SAS-CSI RS), etc., which can be expanded as needed and are not specifically limited in the present disclosure.

The reference signal sending method shown in this embodiment can be executed by a network side device, and the terminal can communicate with the network side device, and the network side device includes but is not limited to network side devices in 4G, 5G, 6G and other communication systems, such as base stations, core networks, etc., and the network side device can communicate with the terminal, and the terminal includes but is not limited to mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices and other communication devices.

[0110] like Figure 8 As shown, the reference signal sending method may include the following steps:

[0111] In step S801, a time domain resource range of a channel state information reference signal SAS-CSI RS dedicated to activation of a secondary cell is determined;

[0112] In step S802, the SAS-CSI RS is sent according to the time domain resource range.

[0113] In one embodiment, the network side device can send (for example, broadcast, unicast, or multicast) a channel state information reference signal SAS-CSI RS dedicated to secondary cell activation, which can be called SCell activation specific CSI RS. For the convenience of description, it is hereinafter referred to as SAS-CSI RS.

[0114] The network side device and the terminal may respectively determine the time domain resource range of the SAS-CSI RS, for example, a time window, and the network side device may send the SAS-CSI RS within the determined time domain resource range, and may send the SAS-CSI RS within the determined time domain resource range according to the configuration information configured to the terminal.

[0115] The configuration information may include the period of the SAS-CSI RS, the number of periods (which can be understood as the number of transmissions), etc. For example, the period is N time slots, N is less than the period threshold M, and M can be set as needed. For example, M=10 can be set. Generally, the minimum value of N is 4, and the N value can be appropriately set to be relatively small so that the terminal can receive the SAS-CSI RS as soon as possible.

[0116] The terminal can receive SAS-CSI RS within a determined time domain resource range, for example, send SAS-CSI RS within a determined time domain resource range according to the configuration information configured by the network side device. After receiving the SAS-CSI RS, the terminal can generate valid CSI based on the SAS-CSI RS and send it to the network side device, and the network side device can determine whether the secondary cell SCell is activated based on the valid CSI.

[0117] According to an embodiment of the present disclosure, the network side device does not continuously send the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation, but only sends the SAS-CSI RS within the time domain resource range. Accordingly, the terminal only needs to receive the SAS-CSI RS within the time domain resource range.

[0118] Accordingly, even if the period of SAS-CSI RS is set relatively small, since the network side device only sends SAS-CSI RS within the time domain resource range, and does not send SAS-CSI RS outside the time domain resource range, the impact on the network side device overhead is small, and the terminal accordingly only receives SAS-CSI RS within the time domain resource range, and does not receive SAS-CSI RS outside the time domain resource range. This is conducive to ensuring that the period of SAS-CSI RS is shortened without significantly increasing network overhead, so that the terminal can receive SAS-CSI RS faster, and then complete the reporting of valid CSI faster to complete the activation of the secondary cell.

[0119] In one embodiment, the manner of determining the time domain resource range includes at least one of the following:

[0120] Set by the network side device;

[0121] Determined according to the agreement.

[0122] In one embodiment, the time domain resource range of the SAS-CSI RS can be determined according to the protocol agreement. In this case, both the network side device and the terminal can determine the time domain resource range of the SAS-CSI RS according to the protocol agreement, and then the network side device can send the SAS-CSI RS within the time domain resource range, and the terminal can receive the SAS-CSI RS within the time domain resource range.

[0123] In one embodiment, the time domain resource range of the SAS-CSI RS can be set by the network side device as needed, and then sent to the terminal through indication information. In this case, the network side device can independently determine the time domain resource range of the SAS-CSI RS, and then indicate the time domain resource range to the terminal through the indication information, so that the network side device can send the SAS-CSI RS within the time domain resource range, and the terminal can receive the SAS-CSI RS within the time domain resource range.

[0124] The indication information may be carried in a MAC CE, and the MAC CE carrying the indication information may reuse the same MAC CE as the MAC CE for activating the temporary RS, or other MAC CEs may be used to carry the indication information.

[0125] Fig. 9 FIG. 1 is a schematic flow chart of another reference signal sending method according to an embodiment of the present disclosure. Fig. 9 As shown, the time domain resource range for determining the channel state information reference signal SAS-CSI RS dedicated to the activation of the secondary cell includes:

[0126] In step S901, a starting position of the time domain resource range is determined in the time domain resources after a temporary reference signal temporary RS is received.

[0127] In one embodiment, the network side device can determine the starting position of the time domain resource range in the time domain resources after sending the temporary RS based on the protocol agreement, and accordingly, the terminal can determine the starting position of the time domain resource range in the time domain resources after receiving the temporary RS based on the protocol agreement.

[0128] For example, the starting position can be determined according to the time slot where the temporary RS is located and an offset offset (greater than or equal to 0 time slots), for example, the starting position is the time slot where the temporary RS is located plus the offset, wherein the offset can be indicated by the network side device, or is also determined according to the protocol agreement.

[0129] In one embodiment, the network side device can be set as needed to determine the starting position of the time domain resource range in the time domain resources after sending the temporary RS, and then can send indication information to the terminal, instructing the terminal to determine the starting position of the time domain resource range in the time domain resources after receiving the temporary RS through the indication information.

[0130] For example, the starting position may be determined according to the time slot where the temporary RS is located and the offset, for example, the starting position is the time slot where the temporary RS is located plus the offset, wherein the offset may be determined according to a protocol agreement or may also be indicated by a network side device.

[0131] In one embodiment, since the network side device configures a temporary RS for the terminal and determines the need to report valid CSI as soon as possible only when the terminal is activated to receive the temporary RS, the starting position of the time domain resource range can be determined in the time domain resources after receiving the temporary RS, so that when the temporary RS is received and it is determined that there is a need to report valid CSI as soon as possible, the terminal starts to receive SAS-CSI RS from the starting position, and accordingly, the network side device can start to send SAS-CSI RS after sending the temporary RS. This is conducive to avoiding the waste of resources caused by the terminal receiving SAS-CSI RS and the network side sending SAS-CSI RS when there is no need to report valid CSI as soon as possible.

[0132] In one embodiment, the method for determining the time domain resource range includes setting by the network side device, and determining the time domain resource range of the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes: determining the starting position of the time domain resource range according to the absolute time position set by the network side device.

[0133] In the case where the network side device instructs the terminal to determine the time domain resource range through the indication information, the network side device may indicate the absolute time position as the starting position of the time domain resource range through the indication information.

[0134] In one embodiment, the method for determining the time domain resource range includes setting by the network side device, and the method for determining the time domain resource range of the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes: determining the starting position of the time domain resource range according to the offset relative to the preset time domain position set by the network side device.

[0135] When the network side device instructs the terminal to determine the time domain resource range through indication information, the network side device can indicate the offset to the terminal, and the terminal can determine the starting position of the time domain resource range based on the preset time domain position and the offset indicated by the network side device. The network side device can also determine the starting position of the time domain resource range based on the preset time domain position and the offset indicated by the network side device.

[0136] The preset time domain position may be determined based on a protocol agreement, or may be indicated in advance by the network side device. For the network side device and the terminal, the offset may be the same, but the preset time domain position may be different.

[0137] For example, for a network side device, the preset time domain position includes at least one of the following:

[0138] The time domain location of sending temporary RS;

[0139] Sending a time domain position of indication information to the terminal, wherein the indication information is used to indicate the time domain resource range;

[0140] A downlink time slot corresponding to the time domain position of the hybrid automatic repeat request HARQ corresponding to the indication information sent by the terminal is received.

[0141] For the terminal, the preset time domain position includes at least one of the following:

[0142] The time domain position of the received temporary RS;

[0143] The time domain location of receiving the indication information;

[0144] The downlink time slot corresponding to the time domain position of the hybrid automatic repeat request HARQ corresponding to the indication information is sent.

[0145] Fig.10 FIG. 1 is a schematic flow chart of another reference signal sending method according to an embodiment of the present disclosure. Fig.10 As shown, the time domain resource range for determining the channel state information reference signal SAS-CSI RS dedicated to the secondary cell activation includes:

[0146] In step S1001, it is determined that the time domain position at which valid channel state information valid CSI generated by the terminal according to the SAS-CSI RS is received is the end position of the time domain resource range.

[0147] In one embodiment, since the terminal has completed the activation / deactivation process of the secondary cell after sending the valid CSI, the SAS-CSI RS is not received after sending the valid CSI (before the next time the secondary cell needs to be activated / deactivated). Therefore, the time domain position (e.g., time slot) for sending the valid CSI can be determined as the end position of the time domain resource range for receiving the SAS-CSI RS. After the end position, the terminal stops receiving the SAS-CSI RS.

[0148] Correspondingly, the network side device may determine the time domain position at which the valid CSI is received as the end position of the time domain resource range for sending the SAS-CSI RS, and after the end position, the network side device stops sending the SAS-CSI RS.

[0149] Fig.11 FIG. 1 is a schematic flow chart of another reference signal sending method according to an embodiment of the present disclosure. Fig.11 As shown, sending the SAS-CSI RS according to the time domain resource range includes:

[0150] In step S1101, when it is determined that a temporary RS is configured for the terminal and the terminal is activated to receive the temporary RS, the SAS-CSI RS is sent according to the time domain resource range.

[0151] In one embodiment, the method further comprises:

[0152] In step S1102, when it is determined that the terminal is not activated to receive a temporary RS or the terminal is not configured with a temporary RS, the SAS-CSI RS is not sent according to the time domain resource range.

[0153] In one embodiment, the network side device determines that there is a need to report the valid CSI as soon as possible only when the network side device configures the temporary RS for the terminal and activates the terminal to receive the temporary RS.

[0154] Therefore, the terminal can receive the SAS-CSI RS according to the time domain resource range only when it is determined that the network side device has configured a temporary RS for the terminal and activated the terminal to receive the temporary RS. However, when it is determined that the network side device has not activated the terminal to receive the temporary RS or has not configured the temporary RS for the terminal, the terminal does not receive the SAS-CSI RS according to the time domain resource range.

[0155] Correspondingly, the network side device may send the SAS-CSI RS according to the time domain resource range only when it is determined that the temporary RS is configured for the terminal and the terminal is activated to receive the temporary RS. However, when it is determined that the terminal is not activated to receive the temporary RS or the temporary RS is not configured for the terminal, the SAS-CSI RS is not sent according to the time domain resource range.

[0156] Accordingly, it is possible to avoid wasting resources due to the terminal receiving the SAS-CSI RS and the network side sending the SAS-CSI RS when there is no need to report the valid CSI as soon as possible.

[0157] In one embodiment, the method further includes: in a case where the SAS-CSIRS is sent according to the time domain resource range, stopping sending other CSI-RS related to activating the secondary cell.

[0158] Since the network side device sends the SAS-CSI RS within the time domain resource range, the terminal can obtain valid CSI according to the SAS-CSI RS for reporting, and there is no need to regenerate valid CSI according to other CSI-RS related to the activation of the secondary cell. Therefore, the network side device can stop (for example, stop within the time domain resource range) sending other CSI-RS related to the activation of the secondary cell (for example, P-CSI-RS of the relevant technology center) to avoid wasting network resources.
