[0046] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0047] In 3GPP's Third Generation (3G) mobile communication systems, such as Wideband Code Division Multiple Access (WCDMA), the logical channel optimization level (LCP) is the only parameter referenced during the logical channel prioritization (LCP) process. For example, two logical channels, LCH_1 and LCH_2, have priorities LCH1_P and LCH2_P, respectively. At a given moment, the buffers for the data they need to send are LCH1_Buf and LCH2_Buf, respectively. The size of the allocated radio resource block is represented by a serving grant (SG). Based on the SG, the terminal can calculate the size of the radio resource block in bytes.

[0048] An example of a method for allocating radio resources to a logical channel is as follows:

[0049] Step 1: Sort the logical channels by priority (assuming that LCH_1 has a higher priority than LCH_2, the first logical channel is LCH_1).

[0050] Step 2: Allocate radio resources to LCH_1. If SG <= LCH_B1, the process ends; otherwise, go to Step 3.

[0051] Step 3: Allocate the remaining radio resources (ie, SG-LCH1_Buf) to LCH_2.

[0052] When the number of logical channels is greater than 2, the method is the same, that is, wireless resources are allocated in order of logical channel priority until all wireless resources are allocated or the last logical channel is allocated.

[0053] This method will cause a "starvation" phenomenon. That is, when the SG is smaller than the sum of the logical channel buffers and the high-priority logical channels always have buffers to send, the low-priority logical channels either cannot be scheduled or receive fewer wireless resources, which cannot meet the basic QoS requirements, thus causing starvation.

[0054] In 3GPP's fourth-generation (4G) and fifth-generation (5G) mobile communication systems, LCP uses a token bucket algorithm to alleviate or even overcome the aforementioned starvation problem. The specific method is as follows:

[0055] Each logical channel is assigned a priority bit rate (PBR) and a token bucket (BS) according to QoS requirements. The token bucket can be represented by PBR_BS. A token variable Bj is also set locally. Each logical channel accumulates Bj over time, but the maximum value does not exceed PBR_BS, that is, Bj = Bj + PBR × T, Bj = min(Bj, PBR_BS). T is the time period between two Bj increment calculations. For example, the steps of LCP are as follows (for ease of description, assume that LCH_1 has a higher priority than LCH_2):

[0056] Step 1: First, allocate radio resources to LCH_1, for example: LCH1_ASG = min(SG, LCH1_Bj, LCH1_Buf), where the radio resources allocated to LCH_1 are the minimum of the SG to be allocated, LCH1's token variable LCH1_Bj, and LCH1's buffer size LCH1_Buf. After allocation, subtract the allocated resources from SG and update LCH1's token variable and buffer size. The formula example is as follows:

[0057] SG = SG - LCH1_ASG, which means subtracting the allocated resources from SG;

[0058] LCH1_Bj=LCH1_Bj-LCH1_ASG, which means that the allocated resources are subtracted from the token variable of LCH1 and the token variable of LCH1 is updated;

[0059] LCH1_Buf=LCH1_Buf-LCH1_ASG, indicating that the allocated resources are subtracted from the cache size of LCH_1, and the cache of LCH_1 is updated.

[0060] If there are still SGs remaining, wireless resources can continue to be allocated to LCH_2, for example: LCH2_ASG = min(SG, LCH2_Bj, LCH2_Buf), which means that the wireless resources allocated to LCH_2 are the minimum value of the remaining SG, LCH_2's token variable LCH2_Bj, and LCH_2's cache size LCH2_Buf.

[0061] After allocation, the allocated resources are subtracted from SG, and the token variable and cache size of LCH_2 are updated. The formula example is as follows:

[0062] SG = SG - LCH2_ASG, which means subtracting the allocated resources from SG;

[0063] LCH2_Bj=LCH2_Bj–LCH2_ASG, which means subtracting the allocated resources from the token variable of LCH_2 and updating the token variable of LCH_2;

[0064] LCH2_Buf = LCH2_Buf – LCH2_ASG, which means subtracting the allocated resources from the LCH_2 cache;

[0065] Step 2: If SG is still greater than 0, allocation can continue in the order of priority of LCH_1 and LCH_2 until the wireless resource SG is allocated or LCH_2 is also allocated.

[0066] This algorithm is also applicable to the case where there are more than two logical channels. Just continue to apply step 1 and step 2 in the same way to the logical channels arranged according to the logical channel priority.

[0067] The above solution overcomes the starvation problem in the 3GPP 3G system to a certain extent, but it cannot completely avoid the starvation problem. This problem is particularly serious when the available radio resources are relatively small compared to the total buffer of the logical channels participating in the LCP.

[0068] The following is an example description:

[0069] In Figure 2, three logical channels, LCH1, LCH2, and LCH3, participate in the LCP process. The boundary between the two blocks in each logical channel represents the tokens Bj accumulated by each logical channel based on the configured PBR. Above Bj is the amount of radio resource demand from each logical channel's buffer relative to Bj. Since the overall schedulable radio resources SG may be less than the sum of the tokens Bj of each logical channel, assuming the logical channel priority order is LCH1, LCH2, and LCH3, according to the above method, after radio resources are allocated to LCH1 and LCH2, the radio resources that can be allocated to LCH3 are very limited and less than its Bj. This means that LCH3 is still experiencing starvation. If schedulable radio resources remain scarce, LCH3 will remain in a state of constant starvation.

[0070] FIG3 is a schematic flow chart of a resource allocation method 300 according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0071] S310. The terminal device obtains second token variables of the multiple logical channels based on the allocatable wireless resources and the first token variables of the multiple logical channels;

[0072] S320. The terminal device allocates the wireless resources among the multiple logical channels based on the second token variables and the logical channel priorities of the multiple logical channels.

[0073] In the embodiment of the present application, the logical channel may generally include a control channel and a traffic channel. The control channel is mainly used to transmit control plane information, and the traffic channel is mainly used to transmit user plane information.

[0074] In the embodiments of the present application, the allocable radio resources may be allocated to the terminal device by the network. The network device may allocate the allocable radio resources to the terminal device through dynamic scheduling, semi-static scheduling, etc. The terminal device may allocate the allocable radio resources to multiple logical channels that it needs to use.

[0075] In an embodiment of the present application, a priority bit rate (PBR) and a token bucket can be set for each logical channel according to QoS requirements, and a first token variable can be set for each logical channel. Each logical channel accumulates the first token variable over time, but the maximum value of the first token variable does not exceed the token bucket. Then, based on the allocable wireless resources and the first token variables of each of the multiple logical channels, the second token variables of each of the multiple logical channels can be adjusted respectively. If the allocable wireless resources are less than the sum of the caches participating in the multiple logical channels, the first token variables of each of the multiple logical channels are adjusted to the second token variables respectively, which can reasonably allocate resources to the multiple logical channels and reduce the starvation problem of the logical channels.

[0076] In one embodiment, the allocable wireless resources include wireless resources participating in logical channel prioritization (LCP), and the LCP includes a process in which the terminal device allocates the allocable wireless resources between the logical channels participating in the LCP according to the logical channel priority. In an embodiment of the present application, the wireless resources of the logical channels participating in the LCP, which may also be referred to as the wireless resources participating in the LCP, may include the sum SG_A of the allocable wireless resources participating in the same LCP in a terminal device. If the number of logical channels participating in the LCP includes N, the LCP may include a process in which the terminal device allocates the SG_A between the N logical channels participating in the LCP according to the logical channel priorities of the N logical channels participating in the LCP.

[0077] In one embodiment, the multiple logical channels include logical channels participating in LCP or a subset of logical channels participating in LCP. In an embodiment of the present application, the token variables of all logical channels participating in LCP (i.e., the full set of logical channels participating in LCP) can be adjusted, and the token variables of some logical channels participating in LCP (i.e., the subset of logical channels participating in LCP) can also be adjusted. For example, the wireless resources participating in LCP are SG_A, and all logical channels participating in LCP are N logical channels. Based on SG_A and the first token variables of the N logical channels, the second token variables of the N logical channels can be adjusted respectively. Based on SG_A and the first token variables of N-1 logical channels among the N logical channels, the second token variables of the N-1 logical channels can be adjusted respectively. N-1 in this example can also be changed to N-2, N-3, etc., which can be flexibly adjusted according to actual needs.

[0078] In one embodiment, the first token variable of the logical channel with the highest priority among the logical channels participating in the LCP remains unchanged. For example, among the N logical channels participating in the LCP, the first token variable of the logical channel with the highest priority is not adjusted, and only the first token variables of the remaining N-1 logical channels are adjusted to the second token variable. This is conducive to ensuring that the logical channel with the highest priority can be allocated more wireless resources in a timely manner, and ensuring the normal scheduling of the logical channel with the highest priority. By analogy, the first token variables of the logical channels whose logical channel priorities are ranked in the first few positions can also be limited to remain unchanged. For example, among the N logical channels participating in the LCP, the first token variables of the logical channels whose logical channel priorities are ranked in the first M positions are not adjusted, and only the first token variables of the remaining NM logical channels are adjusted to the second token variables. N is greater than M.

[0079] In one embodiment, the first token variable of a logical channel is determined based on the previous token variable of the logical channel, the priority bit rate (PBR), and the accumulated time, and the first token variable of the logical channel is less than or equal to the token bucket size of the logical channel, and the accumulated time includes the time interval between two consecutive first token variables starting to accumulate. For example, the first token variable of a logical channel can be accumulated over time starting from 0, for example, the first token variable of a logical channel is equal to the priority bit rate of the logical channel multiplied by the accumulated time, and the formula example can be: Bj=PBR×T. The accumulated time of a logical channel can include the time from the last time wireless resources were allocated to the logical channel to the current time when wireless resources are prepared to be allocated to the logical channel again. If the accumulated first token variable reaches the size of the token bucket, accumulation will no longer continue, and the size of the token bucket will be used as the first token variable to participate in the subsequent wireless resource allocation process.

[0080] In one embodiment, the second token variable of a logical channel is less than or equal to the first token variable of the logical channel. For example, the second token variable of each of the N logical channels is less than or equal to the first token variable of each of the N logical channels. If the allocable wireless resources are less than the sum of the caches of the multiple logical channels involved, the resources can be reasonably allocated to the multiple logical channels according to the adjusted second token variables of the multiple logical channels, and the wireless resources allocated to the high-priority logical channels can be appropriately reduced so that the low-priority logical channels also have the opportunity to be allocated wireless resources. By allowing the high-priority logical channels to tolerate a certain degree of starvation, the starvation degree of the low-priority logical channels is reduced. In this case, the starvation degree of the high-priority logical channels is lower, and the starvation degree of the low-priority logical channels is relatively higher.

[0081] In one embodiment, the adjustment parameters of the first token variable include at least one of the following: the first token variable of the multiple logical channels; the size of the wireless resources; the first distribution function. In an embodiment of the present application, the size of the wireless resources used to adjust the first token variable can be equal to the size of the allocable wireless resources (the size of the wireless resources of the logical channels participating in the LCP configured by the network), or it can be equal to the size of the wireless resources remaining after the last allocation. For example, for the first logical channel among multiple logical channels according to the logical channel priority, the size of the wireless resources used to adjust the first token variable can be equal to the size of the allocable wireless resources. For another example, for the second and subsequent logical channels among multiple logical channels according to the logical channel priority, the size of the wireless resources used to adjust the first token variable can be equal to the size of the wireless resources remaining after the last allocation.

[0082] In one embodiment, the size of the radio resources of the logical channels participating in the LCP is smaller than the sum of the first token variables of the logical channels participating in the LCP. For example, the size SG_A of the radio resources of the logical channels participating in the LCP is smaller than the sum of the first token variables of the N logical channels participating in the LCP.

[0083] In one embodiment, the first distribution function is an incremental function. The value of the incremental function can increase as the value of the function's input parameter increases. For example, if the input parameter of the first distribution function is the sequence number of the logical channel after being sorted according to the logical channel priority, the value of the first distribution function increases as the sequence number of the logical channel increases. Based on the first distribution function, the adjustment range of the token variables of multiple logical channels can increase as the sequence number of the logical channel increases.

[0084] In one embodiment, the second token variable of a logical channel is the difference between the first token variable of the logical channel and a first product, where the first product is the product of the first token variable and the value of the first distribution function of the logical channel; the value of the first distribution function is the value obtained by using the sequence number of a logical channel as the input parameter of the first distribution function. For example, the first distribution function is F(n), where n represents the sequence number of the logical channel, i.e., the nth logical channel. The first token variable of a logical channel is Bj_1, and the second token variable is Bj_2. The relationship between the second token variable and the first token variable of the logical channel can be seen in the following formula: Bj_2 = Bj_1-Bj_1×F(n) = Bj_1(1-F(n)).

[0085] In one embodiment, the first distribution function is used to adjust the first token variables of the multiple logical channels according to the order of priority of the multiple logical channels from high to low. For example, if the value of the first distribution function corresponding to a high priority is smaller, the first token variable of the high priority is adjusted to the second token variable, and the amount required to be reduced is smaller. In comparison, if the value of the first distribution function corresponding to a low priority is larger, the first token variable of the low priority is adjusted to the second token variable, and the amount required to be reduced is larger.

[0086] In one embodiment, the first distribution function, the size of the wireless resource, and the first token satisfy a normalization condition.

[0087] In one embodiment, the normalization condition includes:

[0088] The first token variable of each logical channel in the multiple logical channels is divided by the first difference and multiplied by the value of the corresponding first distribution function to obtain a first value; and the first values ​​of the multiple logical channels are accumulated to be equal to 1; the first difference is equal to the difference between the sum of the first token variables of the logical channels participating in the LCP and the size of the wireless resources of the logical channels participating in the LCP, and the value of the first distribution function is the value obtained by taking the serial number of a logical channel as the input parameter of the first distribution function.

[0089] For example, the sum of the first token variables of the logical channels participating in the LCP is LCH_Bj, and the size of the wireless resources of the logical channels participating in the LCP is SG_A, then the first difference is Delta = LCH_Bj-SG_A. If LCH_Bj is greater than SG_A, then Delta is greater than 0. The first token variable of a logical channel is LCH_n_Bj, then the first value corresponding to the logical channel is (LCH_n_Bj / Delta)×F(n). The cumulative value of the first value of each logical channel can be expressed as Sum((LCH_n_Bj / Delta)×F(n))=1. Among them, n can be counted from 0, then n=0~N-1; n can also be counted from 1, then n=1~N.

[0090] In one embodiment, the terminal device performs LCP on the multiple logical channels based on the second token variables of the multiple logical channels, including:

[0091] Corresponding wireless resources are allocated to each of the multiple logical channels in order of priority from high to low, wherein the size of the wireless resources of each logical channel is the minimum value of the remaining wireless resources, the second token variable of the logical channel, and the cached data amount of the logical channel.

[0092] In one embodiment, when the logical channel is the first logical channel arranged, the remaining radio resources are radio resources of the logical channels participating in the LCP;

[0093] In a case where the logical channel is not the frontmost logical channel, the remaining wireless resources are the remaining wireless resources after the terminal device allocates wireless resources to the previous logical channel.

[0094] In an embodiment of the present application, multiple logical channels may be arranged in descending order of logical channel priority. Then, starting with the first logical channel in the order of arrangement, wireless resources are allocated to each logical channel. The remaining wireless resources of the first logical channel arranged first are equal to all wireless resources of the logical channels participating in the LCP. The remaining wireless resources of the second and subsequent logical channels are equal to the remaining allocatable wireless resources after allocating wireless resources to the previous logical channel.

[0095] For example, there are three logical channels participating in LCP, and the order of logical channel priority from high to low is LCH_1, LCH_2, and LCH_3. The wireless resources of the logical channels participating in LCP include SG_A. First, the second token variable of LCH_1 is obtained based on the first token variable of SG_A and LCH_1, and then the minimum value among SG_A, the second token variable of LCH_1, and the cached data volume of LCH_1 is compared. The wireless resource LCH1_ASG allocated to LCH_1 is equal to the minimum value. Then, the parameters such as the remaining wireless resources SG_R, the first token variable, and the cached data volume are updated with reference to the following formula:

[0096] SG_R = SG_A - LCH1_ASG, which means the resources allocated for LCH_1 are subtracted from the radio resources SG_A of the logical channels participating in the LCP;

[0097] LCH1_Bj2=LCH1_Bj2-LCH1_ASG, which means that after each allocation of wireless resources, the allocated resources are subtracted from the second token variable LCH1_Bj2 of LCH_1, and the second token variable of LCH_1 is updated;

[0098] LCH1_Buf=LCH1_Buf-LCH1_ASG, which means that after each allocation of wireless resources, the allocated resources are subtracted from the buffered data volume LCH1_Buf of LCH_1 to update the buffered data volume of LCH_1.

[0099] If the remaining radio resources SG_R are not zero, the radio resources for LCH_2 can be further allocated. First, the second token variable for LCH_2 is obtained based on the first token variable for SG_A and LCH_2. The minimum value among SG_A, the second token variable for LCH_2, and the buffered data volume of LCH_12 is then compared. The radio resources LCH2_ASG allocated to LCH_2 are equal to this minimum value. The remaining radio resources SG_R, the first token variable, and the buffered data volume are then updated using the following formula:

[0100] SG_R = SG_R – LCH2_ASG, which means the resources allocated to LCH_2 are subtracted from the remaining radio resources SG_B;

[0101] LCH1_Bj2=LCH2_Bj2–LCH2_ASG, indicating that after each allocation of wireless resources, the allocated resources are subtracted from the second token variable LCH1_Bj2 of LCH_2, and the second token variable of LCH_2 is updated;

[0102] LCH2_Buf=LCH2_Buf−LCH2_ASG, indicating that after each allocation of wireless resources, the allocated resources are subtracted from the buffered data volume LCH2_Buf of LCH_2 to update the buffered data volume of LCH_2.

[0103] The remaining radio resources SG_R-LCH2_ASG after being allocated to LCH_2 can continue to be allocated to LCH_3. The specific allocation method is similar to that for LCH_2 and will not be repeated here.

[0104] FIG4 is a schematic flow chart of a resource allocation method 400 according to another embodiment of the present application. The method may include one or more features of the resource allocation method 300 described above. In one embodiment, the resource allocation method 400 further includes:

[0105] S410. The terminal device receives information about radio resources of the logical channels participating in the LCP.

[0106] S420. The terminal device obtains the size of the wireless resources of the logical channel participating in the LCP based on the information of the wireless resources.

[0107] For example, the terminal device receives the SG of the radio resources of the logical channel of the parameter LCP from the network device. Based on the SG, the resource size of the radio resources of the logical channel participating in the LCP in the time domain, frequency domain, spatial domain, etc. can be calculated. In the above resource allocation method, at least one radio resource in the time domain, frequency domain, spatial domain, etc. can be allocated to the logical channel.

[0108] In an embodiment of the present application, when the wireless resources that can be allocated are less than the cache and the logical channels participating in the LCP, the cause of the starvation phenomenon is mainly that the first step of the LCP algorithm of the above-mentioned 4G / 5G system always strictly allocates wireless resources to the logical channels in the order of logical channel priority and the accumulated tokens Bj. When wireless resources are relatively sufficient, this LCP algorithm should enable logical channels with high priority to meet the QoS requirements specified by PBR first. However, when wireless resources are relatively scarce, if the same principle is continued, starvation problems will occur. In order to improve fairness, in this case all logical channels should tolerate a certain degree of starvation, but the degree of starvation of logical channels with high priority is allowed to be lower, while the degree of starvation of logical channels with low priority is relatively large.

[0109] The resource scheduling method of the embodiment of the present application can be understood as a method for scheduling logical channels, which may specifically include: when the allocatable wireless resource SG is less than the sum of Bj of the logical channels participating in the LCP, the difference between the sum of SG and Bj is distributed among the logical channels according to a certain rule. The differences allocated to the logical channels are distributed in descending order according to the order of the logical channel priorities, that is, the proportion of Bj reduced by the logical channel with the highest priority is the lowest, and then increases in sequence. It should be noted that when calculating the difference between the sum of SG and Bj, all logical channels participating in the LCP need to be taken into account. When specifically adjusting Bj, the participating logical channels can be a subset of the logical channels participating in the LCP. For example, the logical channel with the highest priority can be exempted.

[0110] Assume that a logical channel is arranged in order of priority among the logical channels participating in Bj adjustment, and the order is n, and the distribution function of adjusting Bj is F(n), then the value of Bj of this logical channel after adjustment is: LCH_n_Bj=LCH_n_Bj(1–F(n)), n>=0

[0111] After adjusting Bj according to the following method, perform the LCP process according to the LCP method.

[0112] The distribution function F(n) is an incremental function. For example, F(n) is a linear distribution function, such as F(n) = a + b × n, and b>0.

[0113] Assuming that there are N logical channels, the following conditions (i.e., normalization conditions) are satisfied between a, b, N, SG, and Bj: Delta = sum(LCH_n_Bj)-SG, n = 0 to N-1 (1) Sum((LCH_n_Bj / Delta)×F(n)) = 1, n = 0 to N-1 (2)

[0114] Where sum is the sum symbol, Delta represents the difference, and LCH_n_Bj represents the first token variable of the nth logical channel. The following are several allocation examples.

[0115] Example 1:

[0116] Assume that F(n)=a+b×n.

[0117] Assuming N=3, LCH_0_Bj=40, LCH_1_Bj=20, LCH_2_Bj=60, SG=100, a=0, then b needs to meet the following conditions: Delta=120-100=20; 40 / 20×0+20 / 20×b+60 / 20×2b=1.

[0118] So b=1 / 7.

[0119] Substituting the values ​​of a, b, and n into the formula for F(n) yields: F(0) = 0, F(1) = 1 / 7, F(2) = 2 / 7

[0120] The formulas for adjusting Bj are: LCH_0_Bj=LCH_0_Bj=40 LCH_1_Bj=LCH_1_Bj×(1-1 / 7)=120 / 7 LCH_2_Bj=LCH_2_Bj×(1-2 / 7)=300 / 7

[0121] Example 2:

[0122] Assume that F(n)=a+b×n.

[0123] Assuming N=4, LCH_0_Bj=40, LCH_1_Bj=20, LCH_2_Bj=60, LCH_3_Bj=40, SG=130, a=2.5%, then b needs to satisfy the following formula: Delta=160-130=30; 40×2.5%+20×(2.5%+b)+60×(2.5%+2b)+40×(2.5%+3b)=30.

[0124] So b=10%.

[0125] Substituting the values ​​of a, b, and n into the formula for F(n), we can obtain: F(0) = 2.5%; F(1) = 12.5%; F(2) = 22.5%; F(3) = 32.5%.

[0126] The formulas for adjusting Bj are: LCH_0_Bj=LCH_0_Bj×(1-F(0))=40×97.5%=39; LCH_1_Bj=LCH_1_Bj×(1-F(1))=20×87.5%=17.5; LCH_2_Bj=LCH_2_Bj×(1-F(2))=60×77.5%=46.5; LCH_3_Bj=LCH_3_Bj×(1-F(3))=40×67.5%=27.

[0127] Example 3:

[0128] Assume F(n) = a + b × n 2 .

[0129] Assume N=3, LCH_0_Bj=40, LCH_1_Bj=20, LCH_2_Bj=60, SG=91, a=2.5%

[0130] Then b needs to satisfy the following formula: Delta=120-91=29; 40×(2.5%)+20×(2.5%+b)+60×(2.5%+4b)=29.

[0131] So b=10%.

[0132] Substituting the values ​​of a, b, and n into the formula for F(n) yields: F(0) = 2.5%; F(1) = 2.5% + 10% = 12.5%; F(2) = 2.5% + 10% × 4 = 42.5%;

[0133] The formulas for adjusting Bj are: LCH_0_Bj=LCH_0_Bj×(1-2.5%)=39; LCH_1_Bj=LCH_1_Bj×(1-12.5%)=17.5; LCH_2_Bj=LCH_2_Bj×(1-42.5%)=34.5.

[0134] After adjusting Bj using the above example, the token variable used in the process of allocating radio resources also changes to the adjusted Bj. Assuming that the adjusted Bj is marked as BJ_N, the order of logical channel priority is LCH_1 and LCH_2, and the sum of the token variables of LCH_1 and LCH_2 before adjustment is greater than the allocable radio resource SG, the adjusted process example is as follows:

[0135] Step 1: First, allocate radio resources to LCH_1, for example: LCH1_ASG = min(SG, LCH1_Bj_N, LCH1_Buf), where the radio resources allocated to LCH_1, LCH1_ASG, are the minimum of the SG to be allocated, the adjusted token variable LCH1_Bj_N for LCH1, and the buffer size LCH1_Buf for LCH1. After allocation, subtract the allocated resources from SG, and update the adjusted token variable and buffer size for LCH1. The formula example is as follows:

[0136] SG = SG - LCH1_ASG, which means subtracting the allocated resources from SG;

[0137] LCH1_Bj_N=LCH1_Bj_N-LCH1_ASG, which means that the allocated resources are subtracted from the token variable adjusted by LCH1, and the token variable adjusted by LCH1 is updated;

[0138] LCH1_Buf=LCH1_Buf-LCH1_ASG, indicating that the allocated resources are subtracted from the cache size of LCH_1, and the cache of LCH_1 is updated.

[0139] If there are still SGs remaining, wireless resources can continue to be allocated to LCH_2, for example: LCH2_ASG = min(SG, LCH2_Bj_N, LCH2_Buf), which means that the wireless resources allocated to LCH_2 are the minimum value of the remaining SG, the token variable LCH2_Bj_N adjusted by LCH_2, and the cache size LCH2_Buf of LCH_2.

[0140] After allocation, the allocated resources are subtracted from SG, and the token variable and cache size of LCH_2 are updated. The formula example is as follows:

[0141] SG = SG - LCH2_ASG, which means subtracting the allocated resources from SG;

[0142] LCH2_Bj_N=LCH2_Bj_N–LCH2_ASG, indicating that the allocated resources are subtracted from the token variable adjusted by LCH_2, and the token variable adjusted by LCH_2 is updated;

[0143] LCH2_Buf = LCH2_Buf – LCH2_ASG, which means subtracting the allocated resources from the LCH_2 cache;

[0144] Step 2: If SG is still greater than 0, allocation can continue in the order of priority of LCH_1 and LCH_2 in step 1 until the radio resource SG is exhausted. In this way, higher-priority logical channels, such as LCH_1, are allocated fewer resources, allowing lower-priority logical channels to also receive some resources.

[0145] In the embodiment of the present application, by adjusting the token variable of the LCH, all logical channels can be made to tolerate a certain degree of starvation, allowing logical channels with high priority to have a lower degree of starvation, while logical channels with low priority to have a relatively higher degree of starvation. In this way, wireless resources can be more fairly allocated among different logical channels.
