Detailed Description

For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the present application in connection with the accompanying drawings, which are provided for purposes of illustration only and are not intended to limit the embodiments of the present application.

Before explaining the embodiments of the present application, the related contents will be briefly explained.

A schematic diagram of carrier aggregation is shown in fig. 1; another schematic diagram of carrier aggregation is shown in fig. 2; carrier aggregation enables higher system peak rates by jointly scheduling and using resources on multiple component carriers (Component Carrier, CC) so that the NR system can support a larger bandwidth. The spectrum continuity of the aggregated carriers can be divided into: continuous carrier aggregation and discontinuous carrier aggregation; the band on which the aggregated carriers are located can be classified as either the same or not: intra-band carrier aggregation and inter-band carrier aggregation.

There is a unique primary carrier (Primary Component Carrier, PCC) among the carriers in the carrier aggregation, which provides radio resource control (Radio Resource Control, RRC) signaling connections, non-Access Stratum (NAS) functionality, security, and the like. The physical uplink control channel (Physical Uplink Control Channel, PUCCH) is present on and only on the PCC. Secondary carriers (Secondary Component Carrier, SCC) are also present in the carriers in the carrier aggregation, the SCC only providing additional radio resources. The PCC and SCC are collectively referred to as a serving cell. The standard specifies that the aggregated carriers support 5 maximum, i.e. the aggregated maximum bandwidth is 100MHZ, and that the aggregated carriers belong to the same network device. All aggregated carriers use the same cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI), and the network device implements that the C-RNTI does not collide in the cell where each carrier is located. Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, the carrier requiring aggregation must have a downlink carrier for transmitting a downlink signal, may not have an uplink carrier for transmitting an uplink signal, or may have an uplink carrier. And there must be a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and PUCCH of the own cell for the primary carrier cell, and only the primary carrier cell has PUCCH, other secondary carrier cells may have PDCCH, but other secondary carrier cells have no PUCCH.

The secondary cell is configured through RRC dedicated signaling, and the initial configuration state is a deactivation state, and data transmission and reception cannot be performed in the state. After the activation of the SCell by the MAC CE, the SCell can transmit and receive data. This architecture is not an optimal architecture from the point of view of SCell configuration and latency of activation.

Flow diagram of SCell activation by MAC CE, as shown in the figure3, comprising: the network device sends a MAC CE to the terminal device, where the MAC CE is used for Scell activation. After receiving the MAC CE, the terminal device sends a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback to the network device, and in 3ms after sending the HARQ feedback to the network device, the higher layer of the terminal device processes corresponding information, and activates the Scell. Terminal equipment at T _firstSSB After receiving the first SSB, the operations such as radio frequency calibration are performed. Thereafter, the SSB is processed in a time of 2 ms. Finally, the terminal equipment performs measurement and report of the CSI-RS; and the terminal equipment reports the completion of the CSI-RS, namely the SCell activation is realized.

Applicant found that the terminal device is at T _firstSSB The time waiting for the first SSB to be received may be relatively long. Thus, the time for the terminal device to wait for receiving the first SSB may also increase the delay of SCell activation.

In the embodiment of the application, a first signal can be sent to a terminal device through a network device, and SCell activation is realized in an auxiliary mode based on the first signal; the first signal may be a tracking reference signal (Tracking Reference Signal, TRS). However, since the first signal is additionally configured by the network device, there may be a case where the first signal overlaps with the signal such as SSB or CSI-RS on the time domain resource, the embodiment of the present application also proposes to implement SCell activation by transmitting one of the first signal or the reference signal in a case where the first signal overlaps with the reference signal on the time domain resource.

An optional processing flow of the signal transmission method provided in the embodiment of the present application, as shown in fig. 5, includes the following steps:

in step S201, the terminal device determines a time domain resource of the first signal.

In some embodiments, the first signal may be used for secondary cell activation.

In some embodiments, the first signal may be a TRS; optionally, the first signal is a TRS transmitted aperiodically. If the first signal is a TRS, the TRS may be transmitted on the SCell to be activated.

In some embodiments, the terminal device receives a first signaling sent by the network device, and determines a time domain resource of the first signal through the first signaling. In specific implementation, the terminal device may determine that a time domain resource corresponding to P time units offset with respect to a time domain resource for transmitting the first signaling is a time domain resource for transmitting the first signal; namely, the terminal equipment determines the time domain resources corresponding to P time units after the time domain resources of the first signaling are transmitted as the time domain resources of the first signal; the time unit may be a subframe, or a slot, or a time domain symbol. In particular implementations, the first signaling may explicitly indicate time domain resources of the first signal, e.g., the first signaling explicitly indicates a radio frame number, or a subframe number, or a slot number, for transmitting the first signal; in this scenario, the terminal device may directly determine the time domain resource of the first signal according to the first signaling. The first signaling may be carried in RRC signaling, or MAC CE or DCI.

In some embodiments, the time domain resource of the first signal may be a 5 th time domain symbol and a 9 th time domain symbol of a Y-th slot; the time domain resource of the first signal may also be the 5 th time domain symbol of the Y-th time slot and the 9 th time domain symbol of the y+1th time slot; wherein Y is a positive integer.

Step S202, the terminal equipment determines to receive one of the first signal and the second signal based on the position relation between the time domain resource of the first signal and the time domain resource of the second signal; the second signal comprises at least SSB and/or CSI-RS.

In some embodiments, the second signal may also be other types of signals.

In some embodiments, the terminal device determines to receive one of the first signal and the second signal if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition.

In some embodiments, the first condition may include at least one of: the time domain resource of the first signal and the time domain resource of the nth second signal are located in the same time slot, the time domain symbol of the first signal and the time domain symbol of the nth second signal are at least partially overlapped, the time domain resource of the first signal is located in a first number of time domain units before the time domain resource of the nth second signal, and the time domain resource of the first signal is located after the time slot where the nth second signal is located. Wherein N is a positive integer; if the number of the second signals is one, the Nth second signal is the first second signal and is the only second signal; if the number of the second signals is plural, the nth second signal may be a first second signal of the plural second signals, or may be a second signal of the plural second signals, or a third second signal, or a fourth second signal, or the like. The time domain unit may be a time slot, or a sub-time slot, or a time domain symbol, or a sub-frame, or a radio frame, etc.; the time domain symbols may be orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols.

It will also be appreciated that the terminal device does not expect the network device to configure any of the following: the time domain resource of the first signal and the time domain resource of the second signal are located in the same time slot, the time domain symbol of the first signal and the time domain symbol of the second signal are at least partially overlapped, the time domain resource of the first signal is located in a first number of time domain units before the time domain resource of the second signal, the time domain resource of the first signal is located after the time domain resource of the second signal, and the time domain resource of the first signal is located after the time slot where the Nth second signal is located.

For the scenario that the time domain resource of the first signal and the time domain resource of the second signal are located in the same time slot, the time domain resource for transmitting the first signal and a part of the time domain resource for transmitting the second signal may be located in the same time slot, or the time domain resource for transmitting the first signal and the time domain resource for transmitting the second signal may be all located in one time slot; for the scenario that the time domain resource of the first signal and the time domain resource of the second signal are located in the same time slot, the time domain symbol used for transmitting the first signal and the time domain symbol used for transmitting the second signal may partially overlap, may completely overlap, or may not overlap.

The time domain symbol for the first signal and the time domain symbol for the second signal at least partially overlap, which may be that the time domain symbol for transmitting the first signal and the time domain symbol for transmitting the second signal partially overlap, or that the time domain symbol for transmitting the first signal and the time domain symbol for transmitting the second signal completely overlap.

For the scenario that the time domain resource of the first signal is located in a first number of time domain units before the time domain resource of the second signal, the first number of values may be configured by the network device, and the first number of values may also be agreed by a protocol, e.g. the first number of values may be 5ms. If the first number of values is configured by the network device, the first number of values may be configured by a second signaling sent by the network device, or the first number of values may also be determined by a delay parameter configured by the network device. The second signaling configuration sent by the network device through the first number of values may be that the first number of values are indicated directly and displayed in the second signaling sent by the network device. The first number of values is determined by the delay parameter configured by the network device, which may be that the network device sends a second signaling to the terminal device, where the second signaling carries the delay parameter, and both the terminal device and the network device may determine the first number of values based on the delay parameter; specifically, the terminal device and the network device may determine the first number of values based on the delay parameter according to a predetermined manner or a predetermined calculation manner. Wherein the second signaling may be a TRS configuration signaling or a TRS activation instruction.

In some embodiments, the second signaling may be the same signaling as the first signaling, and the first signaling may be different signaling than the second signaling.

The determination of the reception of one of the first signal and the second signal by the terminal device is described below with respect to the scenario in which the second signal is SSB and the second signal is CSI-RS, respectively.

In some embodiments, the second signal is an SSB, and the terminal device determines to receive the SSB if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition.

In a specific implementation, if the first condition includes that the time domain symbol of the first signal at least partially overlaps with the time domain symbol of the nth second signal, the terminal device prohibits receiving the first signal in a time slot to which the overlapping time domain symbol belongs, or the terminal device prohibits receiving the first signal in time domain resources of the first signal.

For example, if the time domain symbol for transmitting the first signal includes 2 time domain symbols, the nth time domain symbol for transmitting the SSB includes 2 time domain symbols, wherein the 1 time domain symbol for transmitting the first signal overlaps with the nth 1 time domain symbol for transmitting the SSB, that is, the 1 time domain symbol for transmitting the first signal is the same as the 1 time domain symbol for transmitting the SSB, the terminal device determines that the first signal is not received in a slot to which the overlapped time domain symbol belongs; alternatively, the terminal device determines that the first signal is not received at the time domain resource of the first signal.

In this way, when the time domain information of the SSB and the time domain information of the first signal satisfy the first condition, only the SSB is transmitted, so that unnecessary transmission of the first signal can be avoided, and further, waste of system network resources caused by transmission of the first signal can be avoided. In the case that the first signal is a TRS, since the TRS is a signal dedicated to the user, the TRS is regarded as data reception of itself; however, in the case that the first condition is satisfied, the TRS is actually an interference signal, and the transmission density of the TRS is large, there is a high probability that the terminal device cannot correctly receive the data; the terminal device frequently monitors the downlink signal, and the complexity and the power consumption of the terminal device are increased. By avoiding unnecessary TRS transmission, the method and the device can solve the problems that the terminal device cannot correctly receive data and the terminal device is high in implementation complexity and high in power consumption caused by TRS.

In other embodiments, the second signal is a CSI-RS, and if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition, the terminal device determines to receive the CSI-RS or receive the first signal.

In a specific implementation, if the terminal device determines to receive the CSI-RS, the terminal device does not receive the first signal. Or if the terminal equipment determines to receive the first signal, the terminal equipment does not receive the CSI-RS in a time domain resource part where the time domain resource of the first signal overlaps with the time domain resource of the CSI-RS; and receiving the CSI-RS in the time domain resources except for the overlapped time domain resources in the time domain resources of the CSI-RS.

In this embodiment of the present application, for different numbers of first signals and different numbers of second signals, the first signals and the second signals include the following cases:

in a first case, if the number of the first signals is one and the number of the second signals is one, the second signals include: a first available second signal of the terminal device.

In a second case, if the number of the first signals is one and the number of the second signals is greater than one, the second signals include: a second number of available second signals of the terminal device, the second number having a value greater than 1.

In a third aspect, if the number of the first signals and the number of the second signals are both greater than one, the second signals include: a second number of available second signals of the terminal device, the second number having a value greater than 1. The first signal includes: a last one of the plurality of first signals.

Wherein the second signal comprises at least one of: a second signal in the Scell activation procedure, a second signal for an activation period (t_activation) of the Scell activation procedure, and a second signal for the Scell activation procedure.

In some embodiments, the second number of values may be configured by the network device, or the second number of values may be determined by at least one of the following parameters: -a type of the secondary cell, a frequency range in which the secondary cell is located, and-a measurement period (SCell measurement cycle) of the secondary cell. The type of the secondary cell may include known (known) or unknown (unknown), and the frequency range in which the secondary cell is located may include FR1 or FR2. Alternatively, since the state of the carrier to be activated can be determined according to at least one of the type of the secondary cell, the frequency range in which the secondary cell is located, and the secondary cell, it can also be understood that the second number of values is determined according to the state of the carrier to be activated.

In some embodiments, when the terminal device needs to carry multiple functions by taking the second signal as SSB, multiple SSBs may be configured, where the second number is denoted by N as an example, and the value of the second number is determined according to the parameter, as shown in table 1: 1) If the secondary cell to be activated is known, the frequency range of the secondary cell is FR1, the measurement period of the secondary cell is equal to or less than 160ms, the second number value is 1, and the use of SSB is time-frequency synchronization; 2) If the secondary cell to be activated is known, the frequency range of the secondary cell is FR1, the measurement period of the secondary cell is more than 160ms, the second number value is 2, and the use of SSB is AGC setting and time-frequency synchronization; 3) If the secondary cell to be activated is unknown and the frequency range of the secondary cell is FR1, executing boundary conditions

The second number of values is 3 and the use of ssb is complex AGC setting and time frequency synchronization; 4) If the frequency range of the secondary cell to be activated is FR2, there is at least one activated service cell in FR2, the target secondary cell supports the SMTC of the terminal equipment, the execution conditions of SSB in the service cell and SSB in the secondary cell are defined according to clause 3.6.3, SSB-PositionInBurst parameter one of the service cell and the secondary cellSo that the second number of values is 1 and the use of ssb is time-frequency synchronization; 5) If the frequency range of the secondary cell to be activated is FR2, at least one activated service cell exists in the FR2, the target secondary cell does not support the SMTC of the terminal equipment, the second signal of the activated secondary cell and the second signal of the activated service cell on the FR2 are QCL-TypeD, and the value of the second number is 0; 6) If the frequency range of the secondary cell to be activated is FR2, when both FR1 and FR2 support primary and secondary cells, an activated service cell does not exist on the FR2, if the target cell is known, the CSI-RS is reported in a semi-static mode, the second number value is 2, and the use of the SSB is AGC setting and time-frequency synchronization; 7) If the frequency range of the secondary cell to be activated is FR2, when both FR1 and FR2 support the primary cell or the primary and secondary cells, an activated serving cell does not exist on the FR2, if the target cell is known, the CSI-RS is reported in a semi-static mode or periodically, the second number of values is 2, and the purpose of the SSB is AGC setting and time-frequency synchronization. Of course, table 1 is merely an example, and the values of N, the values of parameters, and the uses of SSB in table 1 may be flexibly changed based on practical applications.

TABLE 1

In some embodiments, for case three above, there is a multi-beam scenario; in a multi-beam scenario, if the time domain resource of the first signal and the time domain resource of the second signal meet a first condition in any one beam direction, the terminal device determines to receive one of the first signal and the second signal in all beam directions; that is, all the beams as a whole judge whether the corresponding first signal and second signal meet the first condition, and if only the first signal and second signal corresponding to one beam are judged to not meet the first condition, all the beams are considered to not meet the first condition.

For example, as shown in fig. 6, beam 0 corresponds to the TRS0 without filling and the SSB0 without filling in fig. 6, beam 1 corresponds to the TRS1 with diagonal filling in fig. 6 and the SSB1 with diagonal filling in fig. 6, and beam 2 corresponds to the TRS2 with cross-hatching filling in fig. 6 and the SSB2 with cross-hatching filling in fig. 6; if it is determined that the time domain position relationship between TRS0 and SSB0 corresponding to beam 0 and the time domain position relationship between TRS1 and SSB1 corresponding to beam 1 do not satisfy the first condition, the terminal device receives TRS0 and TRS1. If the time domain position relationship between the TRS2 and the SSB2 corresponding to the beam 2 satisfies the first condition, the terminal device does not receive the TRS2 in the beam 2 direction, and only receives the SSB2.

In other embodiments, for case three above, there is a multi-beam scenario; in a multi-beam scenario, if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition in a first beam direction, the terminal device determines to receive one of the first signal and the second signal in the first beam direction; or if the time domain resource of the first signal and the time domain resource of the second signal do not meet the first condition in the second beam direction, the terminal equipment determines to receive the first signal in the second beam direction; that is, whether the first signal and the second signal corresponding to each beam satisfy the condition is independently determined, and the signals are received according to the determination result for each beam.

For example, as shown in fig. 6, for beam 0 and beam 1, the time domain resource location of the trs is before the first number of time domain units before the time domain resource location of the corresponding second SSB, and for beam 2, the time domain resource location of the trs is within the first number of time domain units before the time domain resource location of the second SSB; i.e. beam 0 and beam 1 do not satisfy the first condition, and beam 2 satisfies the first condition. In this scenario, for beam 0 and beam 1, the terminal device may receive the TRS, and perform ACG setting and time-frequency tracking based on the TRS, to implement secondary cell activation; for beam 2, the terminal device may not receive the TRS, perform ACG setting and time-frequency tracking based on the SSB, and implement secondary cell activation. In this scenario, for beam 0, beam 1 and beam 2, the terminal device may not receive TRS, only receive SSB, perform ACG setting and time-frequency tracking based on SSB, and implement secondary cell activation.

In some embodiments of the present application, the method may further comprise:

step S200, a terminal device receives first indication information, where the first indication information is used to indicate the terminal device to receive one of the first signal and the second signal based on a position relationship between a time domain resource of the first signal and a time domain resource of the second signal.

In some embodiments of the present application, the terminal device may further receive one of the first signal and the second signal according to a protocol convention or a default based on a positional relationship between a time domain resource of the first signal and a time domain resource of the second signal.

It should be noted that, in the above embodiment of the present application, the second signal includes: and a second signal available.

Wherein the available second signal may comprise at least one of: the terminal device receives a second signal after the secondary cell activation signaling, the terminal device receives and processes the second signal after the secondary cell activation signaling, and the terminal device receives and processes the second signal after the secondary cell activation signaling and aligned with the reference signal of the activation cell. The reference signal may be an SSB or CSI-RS; the secondary cell activation signaling may be carried in the MAC CE shown in fig. 3.

An alternative process flow of the signal transmission method provided in the embodiment of the present application, as shown in fig. 7, includes the following steps:

in step S301, the network device sends a first signaling to the terminal device.

In some embodiments, the first signaling is used by the terminal device to determine time domain resources of a first signal.

Step S302, network equipment determines to send one of the first signal and the second signal based on the position relation between the time domain resource of the first signal and the time domain resource of the second signal; the second signal comprises at least SSB and/or CSI-RS.

In the embodiment of the present application, the step S301 and the step S302 do not have an execution sequence, and the step S301 may be executed first, then the step S302 may be executed, or the step S302 may be executed first, and then the step S301 is executed. Step S301 and step S302 may also be performed simultaneously.

In some embodiments, the first signal is for secondary cell activation.

In this embodiment of the present application, the description of the first signaling is the same as the description of the first signaling in the signal transmission method shown in fig. 5, and is not repeated here.

In this embodiment of the present application, the description of the second signal is the same as that of the signal transmission method shown in fig. 5, and is not repeated here.

In some embodiments, the network device transmits one of the first signal and the second signal if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition. I.e. the network device transmits only one of said first signal and said second signal; the first signal may be sent by a network device corresponding to the secondary cell to be activated, and the second signal may be sent by a network device corresponding to the serving cell.

In this embodiment of the present application, the description of the first condition is the same as that of the signal transmission method shown in fig. 5 and is not repeated here.

In some embodiments, the first number of values may be configurable by the network device for a scenario in which the time domain resource of the first signal is located within a first number of time domain units before the time domain resource of the second signal in the first condition. If the first number of values is configured by the network device, the first number of values may be configured by a second signaling sent by the network device, or the first number of values may also be determined by a delay parameter configured by the network device. The second signaling configuration sent by the network device through the first number of values may be that the first number of values are indicated directly and displayed in the second signaling sent by the network device. The first number of values is determined by the delay parameter configured by the network device, which may be that the network device sends a second signaling to the terminal device, where the second signaling carries the delay parameter, and both the terminal device and the network device may determine the first number of values based on the delay parameter; specifically, the terminal device and the network device may determine the first number of values based on the delay parameter according to a predetermined manner or a predetermined calculation manner.

In some embodiments, if the second signal includes an SSB, and the time domain resource of the first signal and the time domain resource of the second signal satisfy the first condition, the network device only transmits the SSB and does not transmit the first signal. I.e. in this scenario the terminal device receives only SSB and does not receive the first signal.

In a specific implementation, if the first condition includes that the time domain symbol of the first signal at least partially overlaps with the time domain symbol of the nth second signal, the network device prohibits sending the first signal in a time slot to which the overlapping time domain symbol belongs, or the network device sends the first signal in time domain resources of the first signal.

For example, if the time domain symbol for transmitting the first signal includes 2 time domain symbols, and the nth time domain symbol for transmitting the SSB includes 2 time domain symbols, wherein the 1 time domain symbol for transmitting the first signal overlaps with the nth 1 time domain symbol for transmitting the SSB, that is, the 1 time domain symbol for transmitting the first signal is the same as the nth 1 time domain symbol for transmitting the SSB, the terminal device determines that the first signal is not received in a slot to which the overlapped time domain symbol belongs; alternatively, the terminal device determines that the first signal is not received at the time domain resource of the first signal.

In other embodiments, the network device transmits the CSI-RS or transmits the first signal if the time domain resource of the first signal and the time domain resource of the second signal satisfy a first condition. I.e. in this scenario, the terminal device receives the CSI-RS or the first signal.

In the implementation, if the terminal equipment determines to receive the CSI-RS, the terminal equipment does not receive the first signal. Or if the terminal equipment determines to receive the first signal, the terminal equipment does not receive the CSI-RS in a time domain resource part where the time domain resource of the first signal overlaps with the time domain resource of the CSI-RS; and receiving the CSI-RS in the time domain resources except for the overlapped time domain resources in the time domain resources of the CSI-RS.

In this embodiment of the present application, the description of the second number is the same as the description of the second number in the data transmission method shown in fig. 5, and is not repeated here.

The following describes in detail the processing procedure of the information transmission method provided in the embodiment of the present application, with respect to the first case, the second case, and the third case, respectively, taking the SSB as the second signal and the TRS as the first signal; of course, in the specific implementation, the second signal is not limited to SSB, and may be a second signal such as CSI-RS; the first signal is not limited to TRS, but may be other signals for secondary cell activation.

For case one, the number of SSBs is one and the number of TRSs is one, the implementation of secondary cell activation depends only on the reception of one downlink signal (e.g., SSB). In this scenario, the terminal device needs to determine a positional relationship between the time domain resource of the TRS and the time domain resource of the first available SSB that the terminal device can receive the downlink signal after the carrier to be activated. For example, if the signaling for secondary cell activation is a MAC CE, the first available SSB is the SSB sent 3ms after the transmission of the HARQ-ACK corresponding to the MAC CE; if the signaling for secondary cell activation is DCI, the first available SSB is the SSB sent after N2 time domain symbols after DCI transmission, and N2 time domain symbols are PUSCH processing time.

In some embodiments, if the time domain resources of the TRS are within X1 time slots before the time domain resources of the first available SSB, then the time domain resources of the TRS are considered to be earlier than the time domain resources of the SSB by a lesser amount of time domain resources, and/or the TRS is not necessarily transmitted. If the time domain resource of the TRS and the time domain resource of the first available SSB are in the same time slot, the TRS is transmitted without the effect of reducing the activation delay of the secondary cell, and even the transmitted TRS may cause interference to the SSB. If the time slot for transmitting the TRS is after the time slot for transmitting the first available SSB, the transmission TRS will not only have the effect of reducing the secondary cell activation delay, but also increase the secondary cell activation delay. Thus, if the time domain resource of the TRS is within X1 time slots before the time domain resource of the first available SSB, or the time domain resource of the TRS is within the same time slot as the time domain resource of the first available SSB, or the time slot for transmitting the TRS is after the time slot for transmitting the first available SSB, the terminal device does not receive the TRS and only receives the SSB.

For the first case, an optional schematic diagram of the terminal device transmitting the SSB signal, as shown in fig. 8, where the time domain resource of the TRS is located before the X1 slot before the time domain resource of the first available SSB, that is, as shown in fig. 8, the terminal device receives the TRS0, and performs time-frequency tracking based on the TRS0, so as to implement secondary cell activation. The time domain resource of the TRS is located in the X1 slot before the time domain resource of the first available SSB, i.e. TRS1 as shown in fig. 8, the terminal device does not receive TRS1. The time domain resource of the TRS is in the same time slot as the time domain resource of the first available SSB, i.e. TRS2 as shown in fig. 8, the terminal device does not receive TRS2. The slot for transmitting the TRS is after the slot for transmitting the first available SSB, i.e. TRS3 as shown in fig. 8, the terminal device does not receive TRS3;

for case two, the number of SSBs is multiple and the number of TRSs is one, then the implementation of secondary cell activation depends on the reception of TRSs only once. In this scenario, the terminal device needs to determine a positional relationship between the time domain resource of the TRS and the time domain resource of the nth available SSB after the terminal device is able to receive the downlink signal on the carrier to be activated. The value of N may be determined according to table 1, or may be determined as other values according to at least one of the type of the secondary cell, the frequency range in which the secondary cell is located, and the measurement period of the secondary cell.

For the second case, as shown in fig. 9, the value of N is 2, and the terminal needs to determine the position relationship between the time domain resource of the TRS and the time domain resource of the 2 nd available SSB after the terminal is able to receive the downlink signal on the carrier to be activated. The time domain resource of the TRS is located before the X1 time slot before the time domain resource of the 2 nd available SSB, that is, TRS0 as shown in fig. 9, then the terminal device receives TRS0, and performs time-frequency tracking and AGC setting based on TRS0, so as to implement secondary cell activation. The time domain resource of TRS1 is located in the X1 slot before the time domain resource of the 2 nd available SSB, i.e. TRS1 as shown in fig. 9, the terminal device does not receive TRS1. The time domain resource of the TRS and the time domain resource of the 2 nd available SSB are in the same time slot, i.e. TRS2 as shown in fig. 9, the terminal device does not receive TRS2. The slot for transmitting the TRS is after the slot for transmitting the 2 nd available SSB, i.e. TRS3 as shown in fig. 9, the terminal device does not receive TRS3.

For case three, the number of SSBs is multiple, and the number of TRSs is one more, then the implementation of secondary cell activation depends on multiple TRSs reception. In this scenario, the terminal device needs to determine a positional relationship between the time domain resource of the last TRS in the time domain dimension and the time domain resource of the nth available SSB among the plurality of TRSs. The value of N may be determined according to table 1, or may be determined as other values according to at least one of the type of the secondary cell, the frequency range in which the secondary cell is located, and the measurement period of the secondary cell.

For the third case, as shown in fig. 10, the value of N is 2, and the terminal needs to determine the position relationship between the time domain resource of the last TRS and the time domain resource of the 2 nd available SSB after the terminal is able to receive the downlink signal on the carrier to be activated. The 2 nd available SSB is used for time-frequency tracking (T/F tracking), the time domain resource of the TRS is located before the X1 time slot before the time domain resource of the 2 nd available SSB, that is, as shown in fig. 10, TRS0, then the terminal device receives TRS0, and performs time-frequency tracking based on TRS 0; and performing AGC setting based on TRS0 corresponding to the first SSB to realize activation of the auxiliary cell. The time domain resource of the TRS is located in the X1 slot before the time domain resource of the 2 nd available SSB, i.e. TRS1 as shown in fig. 10, the terminal device does not receive TRS1. The time domain resource of the TRS and the time domain resource of the 2 nd available SSB are in the same time slot, i.e. TRS2 as shown in fig. 10, the terminal device does not receive TRS2. The slot for transmitting the TRS is after the slot for transmitting the 2 nd available SSB, i.e., TRS3 as shown in fig. 10, the terminal device does not receive TRS3.

The "terminal device does not receive" in the embodiment of the present application may be replaced by "terminal device does not detect". For example, the terminal device does not receive the first signal, may be the network device transmits the first signal, but the terminal device does not detect the first signal; the network device may not transmit the first signal, and the terminal device may not detect the first signal.

It should be noted that, the signal transmission method provided in the embodiment of the present application may be at least applied to the secondary cell activation process.
