[0051] 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.

[0052] 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.

[0053] An example of a method for allocating radio resources to a logical channel is as follows:

[0054] 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).

[0055] Step 2: Allocate radio resources to LCH_1. If SG <= LCH_B1, the process ends; otherwise, go to Step 3.

[0056] Step 3: Allocate the remaining radio resources (ie, SG-LCH1_Buf) to LCH_2.

[0057] 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.

[0058] 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.

[0059] 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:

[0060] Each logical channel sets 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 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). Where T is the time period between two Bj increment calculations. For example, the steps of LCP are as follows (for the convenience of description, it is assumed that LCH_1 has a higher priority than LCH_2):

[0061] 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:

[0062] SG = SG - LCH1_ASG, which means subtracting the allocated resources from SG;

[0063] 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;

[0064] 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.

[0065] 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.

[0066] 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:

[0067] SG = SG - LCH2_ASG, which means subtracting the allocated resources from SG;

[0068] 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;

[0069] LCH2_Buf = LCH2_Buf – LCH2_ASG, which means subtracting the allocated resources from the LCH_2 cache;

[0070] 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.

[0071] 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.

[0072] 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.

[0073] The following is an example description:

[0074] 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.

[0075] 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.

[0076] S310. Obtain first parameters corresponding to the multiple logical channels based on data rates of the multiple logical channels;

[0077] S320. Allocate wireless resources to the multiple logical channels based on first parameters corresponding to the multiple logical channels.

[0078] 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.

[0079] In an embodiment of the present application, the network can schedule allocatable wireless resources for the terminal device. The network device can schedule allocatable wireless resources for the terminal device through dynamic scheduling, semi-static scheduling, etc. The terminal device can use multiple logical channels to allocate allocatable wireless resources scheduled by the network device for its own needs. These multiple logical channels may include the full set or subset of logical channels participating in logical channel prioritization (LCP). The LCP includes a process in which the terminal device allocates wireless resources between logical channels participating in the LCP according to the priority of the logical channels. In an embodiment of the present application, wireless resources are allocated between different logical channels based on the parameters obtained from the data rate of the logical channel, which can more reasonably allocate wireless resources. For example, the starvation problem of one or more low-priority logical channels can be alleviated.

[0080] In one embodiment, the first parameter corresponding to a logical channel is used to indicate the level of starvation of the logical channel. For example, a higher value of the first parameter corresponding to a logical channel indicates a higher level of starvation of the logical channel; a lower value indicates a lower level of starvation of the logical channel.

[0081] In one embodiment, there is a negative correlation between the first parameter corresponding to a logical channel and the current data rate of the logical channel. In an embodiment of the present application, the current data rate of a logical channel may include the data rate of the logical channel based on the starting point of a time window to the current time slot. If a time window is 100ms, the current data rate may include the data rate counted from the current time slot back 100ms as the starting point to the current time slot. For example, the higher the current data rate of a logical channel, the smaller the value of the first parameter; the lower the current data rate, the larger the value of the first parameter. The first parameter corresponding to a logical channel and the current data rate of the logical channel may be a linear negative correlation or a nonlinear negative correlation.

[0082] In one embodiment, there is a negative correlation between the first parameter corresponding to a logical channel and the first ratio, which is the ratio of the current data rate of the logical channel to the data rate required by QoS. In an embodiment of the present application, the data rate required by QoS for a logical channel may include a data rate that can meet the QoS requirements of the logical channel. The data rate required by QoS may be preset or calculated based on the QoS requirements. The first ratio can be obtained by dividing the current data rate of a logical channel by the data rate required by QoS for the logical channel. The larger the first ratio corresponding to a logical channel, the smaller the value of the first parameter; the smaller the first ratio, the larger the value of the first parameter. The first parameter corresponding to a logical channel and the first ratio corresponding to the logical channel can be a linear negative correlation or a nonlinear negative correlation.

[0083] In one embodiment, the first parameter corresponding to a logical channel is negatively correlated with the logical channel priority of the logical channel. For example, the greater the logical channel priority of a logical channel, the smaller the value of the first parameter; and the smaller the logical channel priority, the larger the value of the first parameter. The first parameter corresponding to a logical channel and the logical channel priority of the logical channel can have a linear negative correlation or a nonlinear negative correlation.

[0084] FIG4 is a schematic flow chart of a resource allocation method 400 according to another embodiment of the present application. The method 400 may include one or more features of the above-mentioned method. In one embodiment, step S320 allocates wireless resources to the multiple logical channels based on the first parameters corresponding to the multiple logical channels, including:

[0085] S410. Determine, based on a minimum value of the first parameters corresponding to the multiple logical channels, an expected radio resource of a target logical channel among the multiple logical channels;

[0086] S420: Allocate radio resources to the target logical channel based on the expected radio resources of the target logical channel.

[0087] In an embodiment of the present application, multiple logical channels can be first arranged in descending order based on the first parameters corresponding to each of them. The value of the first parameter corresponding to the logical channel arranged at the front is the largest, and the value of the first parameter corresponding to the logical channels arranged at the front and back is the smallest. After sorting, wireless resources can be allocated to the arranged logical channels in sequence. The target logical channel is one of the arranged logical channels. Based on the minimum value of the first parameter, the expected wireless resources of any target logical channel can be determined. Then, based on the expected wireless resources of the target logical channel, wireless resources can be allocated to the target logical channel. Since the first parameter can reflect the degree of hunger, and the first parameter is related to the data rate of the logical channel, determining the expected wireless resources of the target logical channel based on the minimum value of the first parameter is conducive to making multiple logical channels reach the same or similar degree of hunger, thereby allocating wireless resources more fairly and reasonably.

[0088] FIG5 is a schematic flow chart of a resource allocation method 500 according to another embodiment of the present application. The method 500 may include one or more features of the above-described method. In one embodiment, step S410 determines the expected radio resources of the target logical channel among the multiple logical channels based on the minimum value of the first parameter corresponding to the multiple logical channels, including:

[0089] S510: Arrange the multiple logical channels from high to low according to their corresponding first parameters to obtain arranged logical channels, where the logical channels from the first logical channel to the second-to-last logical channel in the arranged logical channels are target logical channels;

[0090] S520: Allocate wireless resources to each target logical channel in sequence based on the minimum value of the first parameters corresponding to the multiple logical channels.

[0091] In an embodiment of the present application, after arranging the logical channels from high to low according to the first parameter, the last logical channel is the logical channel with the smallest first parameter, and the logical channels other than the last logical channel can be used as the target logical channels. For example, according to the first parameters corresponding to N logical channels, from high to low, for the first to N-1th target logical channels in the arranged logical channels, the step of allocating wireless resources to the target logical channels based on the minimum value of the first parameter can be performed. In some cases, the last logical channel in the arranged logical channels can also be the target logical channel.

[0092] FIG6 is a schematic flow chart of a resource allocation method 600 according to another embodiment of the present application. The method 600 may include one or more features of the above-described method. In one embodiment, step S520 allocates wireless resources to each target logical channel in sequence based on the minimum value of the first parameter corresponding to the multiple logical channels, including:

[0093] S610: Select the target logical channel from the arranged logical channels in order;

[0094] S620: Acquire an expected data rate of the target logical channel, where a first parameter of the target logical channel at the expected data rate is equal to a minimum value of the first parameters corresponding to the multiple logical channels;

[0095] S630: Acquire an expected radio resource for the target logical channel based on the expected data rate of the target logical channel, so that after the terminal device acquires the expected radio resource for the target logical channel, the data rate of the target radio resource can be increased to the expected data rate based on the current data rate;

[0096] S640: Obtain radio resources allocated to the target logical channel based on the expected radio resources of the target logical channel, the buffered data volume of the target logical channel, and the allocatable radio resources.

[0097] In an embodiment of the present application, a target logical channel can be first selected from the arranged logical channels, and then the expected data rate of the target logical channel can be determined based on the minimum value of the first parameter. At the expected data rate of the target logical channel, the value of the first parameter corresponding to the target logical channel can be equal to the minimum value, or the difference from the minimum value can be less than a threshold. The expected data rate of the target logical channel may be different from the current data rate of the target logical channel, for example, the expected data rate of the target logical channel is less than the current data rate of the target logical channel. In this case, the expected radio resources of the target logical channel can be calculated based on the expected data rate of the target logical channel. The expected radio resources of the target logical channel, the buffered data amount of the target logical channel, and the available radio resources are then compared to determine the radio resources to be allocated to the target logical channel. The buffered data amount can also be referred to as the buffer size. If the target logical channel is the first logical channel in the arrangement, the available radio resources can include the total radio resources allocated by the network. If the target logical channel is not the first logical channel in the arrangement, the available radio resources can include the remaining radio resources after the radio resources are allocated to the previously arranged logical channels.

[0098] In one embodiment, in step S620, the first parameter of the target logical channel at the expected data rate is equal to a minimum value of the first parameters corresponding to the multiple logical channels, including at least one of the following:

[0099] The first parameter of the target logical channel at the expected data rate is equal to a minimum value of the first parameters corresponding to the multiple logical channels;

[0100] A difference between the first parameter of the target logical channel at the expected data rate and a minimum value of the first parameters corresponding to the multiple logical channels is smaller than a set threshold.

[0101] In an embodiment of the present application, the set threshold may be pre-configured in the terminal device or sent to the terminal device by the network.

[0102] In one embodiment, when the radio resource allocated to the target logical channel is the first logical channel arranged, the minimum value among the network-allocated radio resource size of the target logical channel, the buffered data amount of the target logical channel, and the expected radio resource;

[0103] When the wireless resources allocated to the target logical channel are not the front-most logical channel, the wireless resources allocated to the target logical channel are the minimum value of the remaining wireless resource size of the target logical channel, the cached data amount of the target logical channel and the expected wireless resources.

[0104] For example, the total allocatable wireless resource size sent by the network to the terminal device is SG_A, the target logical channel's buffered data size BF, and the expected wireless resource EP. If the target logical channel is the first channel ranked according to the first parameter, the wireless resource allocated to the target logical channel is SG_1 = Min(SG_A, BF, EP). If the target logical channel is not the first channel ranked according to the first parameter, and the remaining wireless resource size after allocating resources to the previous channel of the target logical channel is SG_R, the wireless resource allocated to the target logical channel is SG_n = Min(SG_R, BF, EP).

[0105] FIG7 is a schematic flow chart of a resource allocation method 700 according to another embodiment of the present application. The method 700 may include one or more features of the above method. In one embodiment, the method further includes:

[0106] S710: After allocating radio resources to each target logical channel, update the remaining radio resource size and the buffered data volume of the target logical channel.

[0107] For example, the wireless resource before allocation to a target logical channel is SG_R, and the wireless resource allocated to the target logical channel is SG_n. After allocation, the remaining wireless resource size is updated to SG_R-SG_n, and the cached data amount of the target logical channel can be updated from BF_1 before allocation to BF_1-SG_n.

[0108] In one embodiment, the method further comprises:

[0109] S720: When the updated remaining radio resource size is greater than 0 after determining radio resources for all target logical channels, allocate the updated remaining radio resources to the multiple logical channels.

[0110] In one embodiment, the methods of allocating the remaining wireless resources after the update to the multiple logical channels include equal allocation, allocation according to the priority of the logical channels, or allocation according to the order of arrangement of the first parameter. For example, if the number of the multiple logical channels is N, the remaining wireless resources after the update can be divided by N and evenly distributed to the N logical channels. For another example, the remaining wireless resources after the update can be allocated according to the priority of the logical channels, with more allocated to those with higher priorities and less allocated to those with lower priorities. Or, allocation can be performed according to the logical channel priority and the token variable. For specific methods, please refer to the relevant description above. For another example, after multiple logical channels are arranged according to their corresponding first parameters, arranged logical channels are obtained. The remaining wireless resources after the update can be allocated in sequence according to the order of the arranged logical channels.

[0111] In one embodiment, the first parameter is represented by the curvature of a first curve. In this embodiment of the present application, a logical channel may have a first curve. The function of the first curve may represent the relationship between the current data rate of the logical channel and the satisfaction level. Therefore, the first curve may also be referred to as a satisfaction curve. A larger value of the first curve may indicate a higher satisfaction level; a smaller value of the first curve may indicate a lower satisfaction level.

[0112] In one embodiment, the first curve increases as the current data rate of the logical channel increases, and the curvature of the first curve decreases as the current data rate of the logical channel increases. For example, the greater the current data rate, the greater the value of the first curve; the smaller the current data rate, the smaller the value of the first curve. The curvature of the first curve can be calculated based on the first curve. For example, the curvature function of the first curve is a function derived from the function of the first curve. The greater the current data rate, the smaller the curvature of the first curve; the smaller the current data rate, the greater the curvature of the first curve.

[0113] In one embodiment, the current data rate of the logical channel includes a statistical data rate of the logical channel up to the current time slot.

[0114] In one embodiment, the constants used to determine the first curve include at least one of the following:

[0115] A first constant is used to represent a data rate set according to the quality of service QoS requirement of the logical channel;

[0116] A second constant is used to represent a scaling factor corresponding to the logical channel priority;

[0117] The third constant is the experience value.

[0118] In one embodiment, the correspondence between the logical channel priority and the scaling factor is configured through the network or set through an empirical value.

[0119] In one embodiment, the function formula of the first curve includes:

[0120] Wherein, F(x) represents the function of the first curve, x represents the current data rate of the logical channel, DR represents the first constant, Z represents the second constant, and B represents the third constant. In the function formula of the first curve, F(x) may increase as x increases and decrease as x decreases.

[0121] In one embodiment, the curvature function formula of the first curve includes:

[0122] Wherein, dF(x) represents the curvature function of the first curve. In the function formula of the first curve, the value of the first parameter dF(x) may decrease as x increases, and increase as x decreases.

[0123] In an embodiment of the present application, the current data rate x of each logical channel is substituted into the curvature function formula to calculate the first parameter of each logical channel. The minimum value of the first parameter of multiple logical channels is then determined. After arranging the multiple logical channels in descending order according to their first parameters, wireless resources can be allocated starting with the first logical channel. Substituting the minimum value of the first parameter calculated above into the curvature function formula for a particular logical channel can calculate the expected data rate of that logical channel. Furthermore, based on the expected data rate of the logical channel, the expected wireless resources for that logical channel can be calculated using a sliding window or other method.

[0124] In some application scenarios, starvation is primarily caused by the fact that the first step of the LCP algorithm in the aforementioned 4G / 5G system always strictly allocates radio resources to logical channels according to the order of logical channel priority and the accumulated tokens Bj. When radio resources are relatively abundant, this LCP algorithm should ensure that high-priority logical channels first meet the QoS requirements specified by PBR. However, when radio resources are relatively scarce, if the same principle is continued, starvation will occur. To improve fairness, in this case, all logical channels should tolerate a certain degree of starvation, but high-priority logical channels are allowed to have a lower degree of starvation, while low-priority logical channels are allowed to have a relatively higher degree of starvation.

[0125] A method for improving logical channel scheduling performance may include introducing a satisfaction curve, where the variable of the curve is the current data rate of the logical channel and the curve increases with increasing data rate, while the curvature of the satisfaction curve decreases with increasing data rate. When the data rate of the logical channel is relatively low, for example, below or close to the PBR, an increase in the data rate causes the satisfaction curve to grow rapidly, indicating that the satisfaction level of the logical channel is relatively low. When the data rate is relatively high, for example, close to the maximum rate, an increase in the data rate causes the satisfaction curve to grow more slowly, indicating that the satisfaction level of the logical channel is relatively high. The curvature of the satisfaction curve and the satisfaction curve value (i.e., the satisfaction level) are exactly opposite, so the curvature of the satisfaction curve can be used to represent the starvation level of the logical channel. From a scheduling perspective, radio resources should be preferentially allocated to the curve with the higher starvation level until their starvation levels are equal. This method is applicable to logical channels with the same logical channel priority. To apply to logical channels with different logical channel priorities, the logical channel priority can be converted into a scaling factor. When using the satisfaction curve, the higher the priority of the logical channel, the larger its scaling factor.

[0126] An example is as follows:

[0127] The satisfaction curve can be expressed as a function. The formula example is as follows:

[0128] x: variable, which is the data rate of the logical channel up to the current time slot;

[0129] DR: Constant, a data rate set according to the QoS requirements of this logical channel;

[0130] Z: constant, scaling factor obtained by looking up the table based on the logical channel priority;

[0131] B: Constant, which can be set based on experience or configured through the network.

[0132] The mapping relationship between the parameter Z and the logical channel priority can also be set based on experience or configured by the network. The following Table 1 is an example of the mapping relationship between the parameter Z and the logical channel priority:

[0133] Table 1

[0134] The smaller the priority value in the table, the higher the priority.

[0135] For example, assuming B = 0.2, an example of a satisfaction curve can be seen in FIG8A , and a curvature curve corresponding to the satisfaction curve can be seen in FIG8B . The horizontal axis of the satisfaction curve and the curvature curve represent the current data rate of the logical channel, the vertical axis of the satisfaction curve can represent the satisfaction level, and the vertical axis of the curvature curve can represent the hunger level.

[0136] An example of a function of the curvature of a satisfactory curve at a variable x is given by the following formula:

[0137] The larger the value of the curvature function, the higher the hunger level.

[0138] An example of a specific method for allocating wireless resources is as follows:

[0139] Step 1: First, count the current data rate of each logical channel. Then, calculate the current curvature of each logical channel according to formula (2), and arrange the logical channels from high to low according to the curvature.

[0140] Step 2: Based on the calculation results in step 1, determine a minimum curvature CV_min

[0141] Step 3: Select the next logical channel in the arranged logical channels (if it is the first selection, the logical channel at the front is selected)

[0142] Step 4: Find a point (i.e., a dr_target) on the satisfaction curve of this logical channel so that the curvature of the logical channel at this point is equal to or close to CV_min

[0143] Step 5: Based on the gap between the current data rate of this logical channel (called dr_current) and the found target point dr_target, calculate the maximum radio resource resource required for this logical channel to meet this gap.

[0144] In steps 4 and 5, the target point dr_target may be the expected target rate dr_expected, and the maximum radio resource resource may be the expected radio resource SG. An example of determining dr_expected and SG is as follows:

[0145] Assuming the rate is estimated using a sliding window of length M milliseconds, the estimated rate is dr_current = sum(TB1, TB2, TB3, ...) / M, where TB is the size of the data block historically sent by this logical channel in the current time window. If the currently allocated resource is SG, the estimated rate is dr_expected = sum(TB2, TB3, ..., SG) / M. This means removing the oldest TB1 and adding the current SG before estimating.

[0146] Assuming the target minimum curvature is CV_min, substitute CV_min into the curvature function in equation (2), and we get dF(dr_expected) = CV_min. The expected data rate dr_expected can be calculated based on the pre-set curvature function. Then, using the sliding window estimation method described above, the expected radio resource SG for the logical channel can be calculated based on dr_expected.

[0147] Step 6: If the current buffer size of the logical channel can be expressed as buffer, the radio resources to be allocated can be calculated as: sg = Min(SG, buffer, resource), where SG is the currently remaining radio resources that can be allocated, and min() is the operation of obtaining the minimum value.

[0148] Step 7: Update the currently allocable radio resource SG = SG-sg, and update the buffer of this logical channel buffer = buffer-sg.

[0149] Step 8: If the updated remaining wireless resource size SG>0, and the current logical channel is not the penultimate logical channel, go back to step 3; otherwise, go to step 9.

[0150] Step 9: If the updated remaining wireless resource size SG>0, these SGs are evenly distributed to each logical channel, or distributed according to the logical channel priority, etc.

[0151] In this embodiment of the present application, the priority and rate requirements of the logical channels are used as parameters of the satisfaction curve. The curvature of the satisfaction curve can be used to represent the degree of radio resource starvation of each logical channel. By ensuring that each logical channel has the same or similar starvation level, radio resources are allocated among different logical channels, which helps to reasonably allocate resources and achieve the goal of fair distribution.
