Description

Timing adjustment method of wireless signal, user equipment and network equipment

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to a timing adjustment method for a radio signal, User Equipment (UE), network Equipment, a chip, a computer-readable storage medium, a computer program product, and a computer program.

Background

In the communication process, the timing advance is set by the uplink channel transmitted by the UE. In the Timing Advance processing, as shown in fig. 1-1, a Timing Advance (TA) amount is sent by the network device to the UE. The timing advance is defined as that the UE sends an uplink timing advance relative to the time of the received downlink signal. Specifically, in the random access process, a TA command may be carried in a random-access response (RAR) of the base station, and a value carried in the TA command may be T _A0,1,2, … 3846. This TA command is applied as an absolute value to the uplink channel of the UE; when the UE is in a normal connection state, the base station can also send a TA (timing advance) adjustment command to the UE; the UE updates the timing advance value according to the TA adjustment command, and determines the TA value based on the timing granularity of the SCS and the adjustment value indicated in the TA adjustment command when updating the timing advance value.

However, with the introduction of BWP, SCS corresponding to different carriers or different BWPs may be different, which may cause timing granularity of different carriers or BWPs to be different, and then the TA adjustment using the scheme provided in the prior art may cause problems such as out-of-range adjustment precision, which affects timing accuracy of the system and processing efficiency of the system.

The communication system 100 also includes at least one UE120 located within the coverage area of the network device 110. "UE" as used herein includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or another UE's device configured to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A UE that is arranged to communicate over a radio interface may be referred to as a "radio communication terminal", "radio terminal" or "mobile terminal".

Optionally, a Device to Device (D2D) communication may be performed between UEs 120.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

An embodiment of the present invention provides a timing adjustment method for a wireless signal, which is applied to a UE, and as shown in fig. 2-1, the method includes:

step 21: receiving first indication information; wherein the first indication information is used for indicating an adjustment amount of an uplink Timing Advance (TA);

step 22: and determining the uplink TA value of at least one transmission resource based on the adjustment quantity of the uplink TA contained in the first indication information and the timing granularity of the subcarrier spacing SCS of the at least one transmission resource.

Correspondingly, the timing adjustment method for a wireless signal provided in this embodiment is applied to a network device, as shown in fig. 2-2, and includes:

step 31: sending first indication information to the UE;

the first indication information is used to indicate an adjustment amount of an uplink Timing Advance (TA), where the adjustment amount of the uplink TA is used to determine an uplink TA value of at least one transmission resource with a timing granularity of a subcarrier spacing (SCS) of the at least one transmission resource.

Wherein the at least one transmission resource may be one of: at least one carrier, at least one BWP, at least one uplink channel. It should be further noted that the transmission resource may further include: at least one carrier and its corresponding SCS, bandwidth size, or at least one BWP and its corresponding SCS and/or bandwidth size.

The first indication information may be information that is indicated for the UE by the network side through dynamic or semi-static signaling. The TA adjusting value is used for adjusting the uplink TA of one or more carriers; accordingly, the first indication information is used to determine one or more carriers or uplink TAs of one or more BWPs.

The network side may use a semi-static signaling as RRC, MAC CE, or the like, and the dynamic signaling may use Downlink Control Information (DCI), that is, the first indication Information may be carried by the DCI.

The signaling for timing adjustment in the prior art is only semi-static, the period of the signaling is as high as hundreds of milliseconds, and the UE cannot achieve the effect of quickly adjusting the timing advance parameter by sending the first indication information through the signaling. Therefore, dynamic signaling is introduced, that is, after the DCI, the UE can be guaranteed to complete uplink timing adjustment quickly within one millisecond based on the first indication information carried in the received DCI.

The first indication information may be a dedicated bit in DCI. Specifically, in the aforementioned dynamic sending of the first indication information for the UE, the dynamic signaling may be in the form of several bit fields in a general physical layer scheduling DCI. The uplink timing adjustment amount is an integer value. For example, the dedicated bit may be a dedicated bit; when the special bit takes a value of 0, it can indicate that TA is decreased by one advance unit. A value of 1 indicates that TA is increased by one advance unit.

The value of the advance unit is related to the allocated SCS of BWP, and the advance unit can be understood as timing granularity. SCS of BWP is 2^u15kHz, the timing granularity of its upstream transmission x.16.64. T_c/2 ^μ. That is, the timing granularity may be multiple T_cThe value is obtained. Wherein, T_cIs the minimum time unit used by the physical layer interface and is defined as

x may be a preset parameter, whose value is equal to 1, or may be greater than 1, and is set according to an actual situation, which is not limited herein.

The UE mainly generates a new uplink TA value by using the uplink timing adjustment amount in the first indication information and the original uplink TA.

Further, the scheme provided by this embodiment is more suitable for the scenario where the SCS of the carriers is different or the SCS of BWPs is different, and the UE may only receive the first indication information that conforms to all BWP timing granularities.

In this embodiment, the concept of multi BWP is explained as follows, one UE may activate multiple uplink BWPs, and may simultaneously transmit signals of multiple BWPs. Also, each BWP may be configured with a specific SCS. One UE may be activated BWP for multiple different SCS's.

The following describes the scheme provided in this embodiment with reference to a plurality of processing scenarios:

scenario 1, in this scenario, the at least one transmission resource may be at least one carrier, or at least one BWP. Mainly aiming at the situation that one or more carriers or one or more BWPs are activated at the UE side at the same time, the specific processing is as follows:

and selecting the largest SCS from the SCSs of the at least one transmission resource as a first SCS, and using the transmission resource corresponding to the first SCS as a first transmission resource.

In addition, a transmission resource other than the first transmission resource among the plurality of transmission resources is referred to as a second transmission resource.

The determining an uplink TA value of the at least one carrier or the at least one BWP based on the uplink timing adjustment included in the first indication information and the timing granularity of the subcarrier spacing SCS of the at least one transmission resource includes:

calculating to obtain a first uplink TA value of the first transmission resource based on a timing unit of the first SCS and the adjustment amount of the uplink TA;

and calculating a second uplink TA value of the second transmission resource based on the timing granularity of the SCS of the second transmission resource except the first transmission resource and the first uplink TA value.

Since the second transmission resource in this scenario may be a plurality of second transmission resources. And each second transmission resource is processed in the same manner to obtain a corresponding second uplink TA value.

The calculating, based on the timing granularity of the first SCS and the adjustment amount of the uplink TA, a first uplink TA value of the first transmission resource may specifically include:

and obtaining the uplink timing adjustment value of this time based on the granularity of the first SCS and the adjustment quantity of the uplink TA, and taking the sum of the original uplink TA value of the first transmission resource and the uplink timing adjustment value as the first uplink TA value of the adjusted first transmission resource.

The formula used may be: n is a radical of_{TA_new1}＝(N _{TA_old1}+(T _A-31)·16·64/2 ^μ1)。

Wherein: μ 1 is the SCS coefficient of the first transmission resource, i.e. SCS 2^u1·15kHz；T _AIs an indication value, N, of the timing advance command_{TA_old1}The original uplink TA value of the first transmission resource; n is a radical of_{TA_new1}The new uplink TA value of the first transmission resource is calculated for the first uplink TA value of the first transmission resource, that is, based on the original uplink TA value and the timing granularity of the first SCS.

The SCSs of the second transmission resources are smaller than the first SCS. Each second transmission resource may be processed in a manner provided in this scenario.

When the calculating a second uplink TA value of the second transmission resource based on the timing granularity of the SCS of the second transmission resource except the first transmission resource and the first uplink TA value of the first transmission resource may include:

rounding based on the first uplink TA value and the calculation result of the SCS coefficient of the second transmission resource; and calculating to obtain a second uplink TA value of the second transmission resource based on the result obtained by the rounding and the timing granularity of the SCS of the second transmission resource.

In the processing of the calculation, since the timing granularity of the second transmission resource is smaller than the timing granularity of the first transmission resource, rounding processing is required.

The formula used may be: n is a radical of_{TA_new2}＝Round((N _{TA_new1})/2 ^μ1-μ2)·16·64/2 ^μ2。

Wherein: μ 2 is the SCS coefficient of one of the plurality of SCS smaller second transmission resources, i.e. SCS 2^u215 kHz; the timing granularity of SCS corresponding to the second transmission resource is 16.64.T_c/2 ^μ2；N _{TA_new1}A first uplink TA value for the first transmission resource; (N)_{TA_new1})/2 ^μ1-μ2May be a calculation result based on the first uplink TA value and SCS coefficients of the second transmission resource, Round () is a rounding calculation, N_{TA_new2}And a second uplink TA value for a second transmission resource.

The rounding calculation in the formula is rounding calculation by Round (); in addition, the rounding operation may be calculated by using floor () or ceiling () instead of Round (), and as long as rounding calculation can be performed, the rounding calculation is within the protection range of the present embodiment and is not exhaustive.

How to perform uplink timing adjustment based on the first uplink TA value and the plurality of second uplink TA values may include the following processing manners:

in a first mode, the uplink timing of the second transmission resource is adjusted based on the second uplink TA value;

and adjusting the uplink timing of the first transmission resource based on the first uplink TA value of the first transmission resource.

That is, the uplink timing of the first transmission resource is directly adjusted based on the first uplink TA value, and the uplink timings of the second transmission resources are respectively adjusted based on the second uplink TA values.

And secondly, aiming at the first transmission resource, the uplink timing adjustment can be directly carried out by adopting the first uplink TA value.

For a different second transmission resource, the following may be used:

determining a difference value between a second uplink TA value of the second transmission resource and a first uplink TA value of the first transmission resource;

when the difference value is larger than a preset precision range, timing advance adjustment is not carried out;

and when the difference value is not larger than the preset precision range, adjusting the uplink timing of the second transmission resource based on the second uplink TA value.

Specifically, multiple second transmission resources may be respectively compared with the first transmission resource, for example, if one second transmission resource does not exceed the corresponding precision range compared with the uplink TA value of the first transmission resource, the timing advance adjustment may be performed on the second transmission resource based on the uplink TA value of the second transmission resource; otherwise, the timing advance adjustment is not performed on the second transmission resource.

The accuracy ranges may be timing advance accuracy ranges respectively corresponding to different SCS of different second transmission resources. For example, SCS-1 may correspond to a first accuracy range and SCS-2 may correspond to a second accuracy range.

Taking the following table 1 as an example, when the SCS is 15kHz, the first uplink TA value (N) is subtracted from the second uplink TA value of the second transmission resource_{TA_new2}-N _{TA_new1}) The result obtained was 128T_cThen it may be determined that uplink timing adjustment is to be performed on the second transmission resource based on the second uplink TA value, if the result is 288T_cThen no uplink timing adjustment may be made for the second transmission resource. Examples of the accuracy ranges corresponding to other SCS are also listed below and are not exhaustive.

TABLE 1

SCS(kHz)	15	30	60	120
Precision range (Tc)	±256	±256	±128	±32

In addition, the first uplink TA value and the second uplink TA value may each include an offset, and the offset is preconfigured or configured by the network device.

It should be further noted that, for at least one second transmission resource, after obtaining the corresponding second uplink TA value, it is further required to:

taking the second uplink TA value as an indication TA value of the second transmission resource;

when transmitting the uplink signal in the second transmission resource, transmitting the uplink signal by using the indication TA value; wherein the error of the transmission is within a preset error range.

Here, the generation of the transmission error may be understood to be caused by a device of the UE side itself, for example, a transmission device of the UE side itself, or an error of a clock device (for example, a clock oscillator) of the UE side itself.

The preset error range can be seen in the following table 2:

SCS(kHz)	15	30	60	120
error range (Tc)	±256	±256T	±128	±32

That is, when the second transmission resource is SCS 30KHz, the uplink signal is transmitted with a transmission error of ± 256T_cWithin. If the error range is not satisfied, the transmission may be controlled to stop.

In the scheme of this scenario, the first uplink TA value may further include an offset, and the second uplink TA value may further include an offset, and the adjusted one or more second uplink TA values may be obtained respectively. For example, may be at N_TAMay be added with one N_TA,offsetIs a constant and can be 0 or other positive integer. The value of the offset may be determined implicitly by other configurations. It may also be pre-configured by network device signaling.

Taking fig. 3 as an example for illustration, the time point when the UE receives the signal may be a time limit of a downlink frame, and the downlink frame may be a currently received downlink frame of a plurality of downlink framesOne, which may be referred to as a downlink frame i. A plurality of transmission resources may be included in the corresponding uplink frame i, which is illustrated in fig. 3 by taking the transmission resource as BWP as an example, and the uplink frame i includes two BWPs, which are BWP #0 and BWP #1, respectively. Assuming that the SCS of BWP #0 is greater than the SCS of BWP #1, BWP #0 may be referred to as a first BWP and BWP #1 as a second BWP; according to the description of the foregoing solution, a first uplink TA value of BWP #0 is calculated, and then uplink timing of BWP #0 is adjusted based on the first uplink TA value; the second upstream TA value of BWP #1 may be calculated by rounding the first upstream TA value of the first BWP and then calculating the timing granularity of the second upstream TA value, and performing upstream timing adjustment according to the second upstream TA value, as shown in the figure, there is a certain increment after upstream timing adjustment of BWP #1 relative to BWP # 0. Fig. 3 also shows the use of the offset, for example, for BWP #0, that is, the first uplink TA value (N) finally obtained_TA) Is increased by the offset (N)_TA,offset) The obtained result is used as the first upstream TA value of BWP #0 finally obtained by the adjustment.

In the prior art, when uplink BWP with different SCS assigned to carriers is activated, the UE can only receive one timing adjustment signal at a time. The scheme provided by the present scenario can perform advanced adjustment based on the maximum BWP of the timing adjustment signal SCS, and perform approximate rounding on the other BWPs to solve the problem of out-of-range corresponding timing granularity and adjustment accuracy.

Scene 2,

The at least one transmission resource in this scenario may be primarily at least one BWP. The difference from scenario 1 is that in this scenario when the BWP of one carrier switches after the TA command is implemented, if the SCS of the target BWP to switch to is smaller than the SCS of the original BWP, the new timing advance is approximately rounded to the timing granularity that conforms to the BWP. It should be noted that the present scenario may be used in combination with scenario 1, that is, on the basis of scenario 1, when the uplink TA values corresponding to multiple carriers or multiple BWPs are determined, and then the original BWP needs to be switched to the target BWP, the scheme provided by the present scenario is adopted.

Specifically, the method comprises the following steps:

if the original BWP is switched to the target BWP and the SCS of the target BWP is not less than the SCS of the original BWP, taking the uplink TA of the original BWP as the uplink TA of the target BWP;

and if the original BWP is switched to the target BWP and the SCS of the target BWP is smaller than the SCS of the original BWP, calculating to obtain the uplink TA value of the target BWP by adopting the uplink TA value of the original BWP and the timing granularity of the SCS corresponding to the target BWP.

In the calculation process for calculating the uplink TA value of the target BWP, the granularity at timing of the SCS of the target BWP is smaller than the granularity at timing of the SCS of the original BWP, so the rounding process is required. The method specifically comprises the following steps:

rounding based on the ascending TA value of the original BWP and the calculation result of the SCS coefficient of the target BWP; and calculating the ascending TA value of the target BWP based on the result obtained by rounding and the timing granularity of the SCS of the target BWP.

That is, when the SCS of the target BWP to which to switch is less than the SCS of the original BWP, the timing employed by the new BWP is rounded based on the timing particles to which its SCS corresponds. It can be calculated as follows:

N _{TA_new2}＝Round((N _{TA_new1})/2 ^μ1-μ2)·16·64/2 ^μ2。

wherein μ 1 is the SCS coefficient of the original BWP, i.e., SCS of the original BWP is 2^u115 kHz; μ 2 is the SCS coefficient of the switching target BWP; round () is a Round operation; the TA value adopted by the original BWP is N_{TA_new1}，N _{TA_new2}An upstream TA value of target BWP, (N)_{TA_new1})/2 ^μ1-μ2I.e. the aforementioned second value.

Similarly, the rounding calculation in the formula is a rounding calculation by using Round (); in addition, the rounding operation may be calculated by using floor () or ceiling () instead of Round (), and as long as the forensic calculation is within the protection range of the present embodiment, the rounding is not exhaustive.

The method further comprises the following steps: and adjusting the uplink timing of the target BWP based on the obtained uplink TA value of the target BWP. At this time, it can be understood that when the upstream TA value of the target BWP is the same as the upstream TA value of the original BWP, the upstream timing is adjusted by using the upstream TA value that can be adjusted; and when the ascending TA value of the target BWP is different from the ascending TA value of the original BWP, adjusting the ascending timing of the target BWP by adopting the newly calculated ascending TA value of the target BWP.

In this scenario, as shown in fig. 4, BWP #0 of the upstream frame i is the original BWP, and the upstream frame i +1BWP #1 is the target BWP; wherein the SCS of BWP #0 is greater than the SCS of BWP # 1. And taking the starting point of the downlink frame i as the time point when the UE receives the signal. Firstly, determining an uplink TA value of BWP #0 according to an adjustment amount of the uplink TA which can be controlled by a TA command, wherein the adjustment amount can comprise an offset value and the TA value; when switching from BWP #0 to BWP #1, rounding calculation is performed based on the TA value of BWP #1 and the TA value of BWP #0, determining the TA value of BWP #1, and performing upward timing adjustment based on the TA value of BWP # 1. In addition, as can be seen from the figure, the difference between BWP #0 and the time point when the UE receives the signal is its uplink TA value; the difference between the start of BWP #1 relative to BWP #0 represents the increment between the upstream TA value of BWP #1 relative to the upstream TA value of BWP # 0.

Scene 3,

In this scenario, the at least one transmission resource may be at least one uplink channel. The difference between the two scenarios is that the present scenario is used in a case where SCS of different uplink channels caused by uplink channel switching is different. The present scenario may be used in combination with scenario 1 and/or scenario 2, for example, after scenario 1 is completed, after uplink TAs of multiple carriers or multiple BWPs are determined, when an uplink channel needs to be switched, the scheme provided by the present scenario may be adopted; after the processing of scenario 1 is completed, when BWP needs to be switched, the processing may be performed based on the scheme of scenario 2, and then if uplink channel switching needs to be performed, the processing may be performed using this scenario.

Specifically, the method comprises the following steps:

if the newly transmitted SCS of the uplink channel is adjusted, when the newly transmitted SCS of the uplink channel is not less than the SCS of the original uplink channel, the uplink TA of the original uplink channel is adopted as the TA of the newly transmitted uplink channel;

if the newly transmitted SCS of the uplink channel is adjusted, when the newly transmitted SCS of the uplink channel is smaller than the SCS of the original uplink channel, the uplink TA value of the original uplink channel and the timing granularity of the newly transmitted SCS of the uplink channel are adopted to calculate and obtain the uplink TA value of the newly transmitted uplink channel.

And when the SCS of the newly transmitted uplink channel is smaller than the SCS of the signal transmitted by the uplink last time, the timing adopted by the newly transmitted channel is rounded based on the timing particles corresponding to the SCS, and the uplink TA value of the newly transmitted uplink channel is determined by combining the uplink TA value of the original uplink channel. For example, it may include:

rounding based on the uplink TA value of the original uplink channel and the calculation result of the newly transmitted SCS coefficient of the uplink channel; and calculating to obtain an uplink TA value of the newly transmitted uplink channel based on the result obtained by the rounding and the timing granularity of the SCS of the newly transmitted uplink channel.

It can be calculated as follows:

N _{TA_new2}＝Round((N _{TA_new1})/2 ^μ1-μ2)·16·64/2 ^μ2。

wherein: mu 1 is SCS coefficient of original uplink transmission signal; mu 2 is SCS coefficient of newly transmitted uplink channel; round () is a Round operation; n is a radical of_{TA_new1}Is the uplink TA value of the uplink channel last time.

Similarly, the rounding calculation in this scenario may also adopt floor () or ceiling ().

The method further comprises the following steps: and adjusting the uplink timing of the newly transmitted uplink channel based on the obtained uplink TA value of the newly transmitted uplink channel. For example, when the SCS of the newly transmitted uplink channel is equal to or greater than the SCS of the original uplink channel, the uplink timing adjustment may be performed on the newly transmitted uplink channel by using the original uplink TA value; otherwise, the uplink TA value of the newly transmitted uplink channel is calculated by using the timing granularity of the SCS of the newly transmitted uplink channel and the uplink TA value of the original uplink channel, and the uplink timing is adjusted by using the new uplink TA value of the newly transmitted uplink channel.

In this scenario, the uplink channel may be a logical channel, that is, a bearer for the UE to send data to the network side, for example, the uplink channel may be a PUSCH, a PUCCH, or the like.

It should be further noted that the uplink TA values finally obtained in scenarios 2 and 3 may also include offsets, which are not described in detail.

In the scenarios 2 and 3, when the transmission SCS is changed due to the switching of the BWP in one carrier or the transmission SCS is changed due to other reasons (for example, the SCS is changed due to the switching of the uplink channel in the scenario 3), the uplink TA value corresponding to the new BWP or the new uplink channel may be quickly adjusted based on the timing granularity corresponding to the SCS of the new BWP or the new uplink channel and the uplink TA of the original BWP or the original uplink channel, so as to solve the problem of adjusting the timing granularity when the SCS is changed.

Finally, it should be noted that the method for calculating the TA value according to the difference of the SCS in the present embodiment may also be used in other timing dynamic calculations, which are not exhaustive here.

It can be seen that, by adopting the above scheme, when SCS corresponding to transmission resources is different, uplink TAs of different transmission resources can be respectively determined based on the indicated adjustment amount of the uplink TA. Therefore, the uplink TA of different transmission resources can be determined under the condition that the timing granularity of different SCS is different, the timing accuracy of the system is improved, and the processing efficiency of the system is ensured.

The rounding calculation in the formula is rounding calculation by Round (); in addition, the rounding operation may be calculated by using floor () or ceiling () instead of Round (), and as long as the forensic calculation is within the protection range of the present embodiment, the rounding is not exhaustive.

How to perform a adjustment based on the first uplink TA value and the plurality of second uplink TA values when activating the plurality of carriers/BWPs may include the following processing manners:

in a first mode, the first processing unit 42,

adjusting uplink timing of the second transmission resource based on the second uplink TA value;

That is, uplink timing of the first carrier or the first BWP is adjusted directly based on the first uplink TA value, and uplink timing of the plurality of second carriers or the plurality of second BWPs is adjusted based on the plurality of second uplink TA values, respectively.

The accuracy ranges may be timing advance accuracy ranges respectively corresponding to different SCS of different second transmission resources.

It is further noted that, after obtaining the corresponding second uplink TA value for at least one second BWP or at least one carrier, it is further required to:

Scene 2,

Specifically, the method comprises the following steps:

N _{TA_new2}＝Round((N _{TA_new1})/2 ^μ1-μ2)·16·64/2 ^μ2。

wherein μ 1 is the SCS coefficient of the original BWP, i.e., SCS of the original BWP is 2^u115 kHz; μ 2 is the SCS coefficient of the switching target BWP; round () is a Round operation; the TA value adopted by the original BWP is N_{TA_new1}，N _{TA_new2}Is the upstream TA value of the target BWP.

The first processing unit 42 adjusts the upstream timing of the target BWP based on the obtained upstream TA value of the target BWP. At this time, it can be understood that when the upstream TA value of the target BWP is the same as the upstream TA value of the original BWP, the upstream timing is adjusted by using the upstream TA value that can be adjusted; and when the ascending TA value of the target BWP is different from the ascending TA value of the original BWP, adjusting the ascending timing of the target BWP by adopting the newly calculated ascending TA value of the target BWP.

That is, the first processing unit 42 performs rounding based on the uplink TA value of the original uplink channel and the calculation result of the SCS coefficient of the newly transmitted uplink channel; and calculating to obtain an uplink TA value of the newly transmitted uplink channel based on the result obtained by the rounding and the timing granularity of the SCS of the newly transmitted uplink channel. It can be calculated as follows:

N _{TA_new2}＝Round((N _{TA_new1})/2 ^μ1-μ2)·16·64/2 ^μ2。

wherein: μ 1 is the SCS coefficient of the signal transmitted in the uplink last time, i.e., SCS of the signal transmitted in the uplink last time is 2^u115 kHz; mu 2 is SCS coefficient of new channel;round () is a Round operation; n is a radical of_{TA_new1}Is the uplink TA value of the uplink channel last time.

The first processing unit 42 adjusts uplink timing of the newly transmitted uplink channel based on the obtained uplink TA value of the newly transmitted uplink channel. For example, when the SCS of the newly transmitted uplink channel is equal to or greater than the SCS of the original uplink channel, the uplink timing adjustment may be performed on the newly transmitted uplink channel by using the original uplink TA value; otherwise, the uplink TA value of the newly transmitted uplink channel is calculated by using the timing granularity of the SCS of the newly transmitted uplink channel and the uplink TA value of the original uplink channel, and the uplink timing is adjusted by using the new uplink TA value of the newly transmitted uplink channel.

It should be further noted that the uplink TAs finally obtained in the scenarios 2 and 3 may also include offsets, which are not described again.

It can be seen that, by adopting the above scheme, when SCS corresponding to transmission resources is different, uplink TA of different transmission resources can be respectively determined based on the indicated uplink timing adjustment amount.
