Description

A resource allocation method and device

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource allocation method and apparatus.

Background technique

When a user equipment (user equipment, UE) sends uplink data, the UE requests the base station to allocate resources for the UE, and then the UE allocates resources to multiple logical channels of the UE for the UE to send uplink data.

Generally, the UE can allocate resources for multiple logical channels between the UE and the base station. Specifically, the UE can allocate resources according to the configuration parameters of the multiple logical channels. The configuration parameters of the logical channels can include the priority and priority of the logical channels. bit rate (prioritised bit rate, PBR), etc. For example, the UE may allocate resources to multiple logical channels that satisfy the respective PBRs of the multiple logical channels according to the priority of the logical channels from high to low. Exemplarily, it is assumed that there are 4 logical channels (including logical channel 1, logical channel 2, logical channel 3, and logical channel 4) between the UE and the base station, where the priority of logical channel 1>the priority of logical channel 2> The priority of logical channel 3 > the priority of logical channel 4, where the priority of logical channel 1 > the priority of logical channel 2, indicating that the priority of logical channel 1 is higher than the priority of logical channel 2, if the four The PBR of the logical channels is the same, which is 10Mbit/s. Assuming that the base station configures 100Mbit resources for the UE, the UE can allocate the 100Mbit resources to the four logical channels in sequence according to the priority of the logical channels.

The concept of network slicing is introduced in 5G networks, where a network slice may include one or more logical channels. For example, network slice 1 may include the above-mentioned logical channel 1, logical channel 2 and logical channel 3, and network slice 2 may include the above-mentioned logical channel 1, logical channel 2, and logical channel 3. Logical channel 4 above. If there are remaining resources after allocating resources to multiple logical channels according to the priorities of the logical channels, the UE continues to allocate the remaining resources to all or part of the multiple logical channels according to the priorities of the logical channels. For example, the above 4 After each logical channel is allocated 10Mbit resources (that is, the four logical channels are allocated 40Mbit resources in total), there are still 60Mbit resources remaining, and the UE can allocate all the 60Mbit resources to the logical channel with the highest priority, That is, logical channel 1. At this time, logical channel 1 is allocated 70Mbit resources, logical channel 2, logical channel 3 and logical channel 4 are allocated 10Mbit resources respectively, that is, network slice 1 is allocated 90Mbit resources, and network slice 2 is allocated 10Mbit resources Resources.

Assume that the target rate of network slice 1 is 50Mbit/s (the amount of resources required to transmit data per unit time), the target rate of network slice 2 is 30Mbit/s, and the resources allocated to network slice 1 (90Mbit) are greater than the network slice. 1 The resources consumed in a unit time, the resources allocated by the network slice 2 (10Mbit) are less than the resources consumed by the network slice 2 in a unit time. Obviously, the above-mentioned allocation of resources according to the priority of the logical channel and the PBR of the logical channel The method does not match the rate requirement of the network slice (for example, the resources allocated to the network slice 2 are smaller than the target rate of the network slice 2), which makes the resource allocation unreasonable and affects the efficiency of data transmission.

With reference to the communication system shown in FIG. 2, the resource allocation method provided by the embodiment of the present invention is completely described below from the perspective of the interaction between the UE and the network device (such as a base station) in the communication system, so as to illustrate that the UE obtains network slice configuration information and logical channels The process of configuring information and the process of allocating resources to one or more logical channels of the UE according to the network slice configuration information and the logical channel configuration information.

As shown in FIG. 5 , the resource allocation method provided by the embodiment of the present invention may include S101-S105:

S101. A network device determines network slice configuration information and logical channel configuration information.

Wherein, the network slice configuration information includes configuration information of multiple network slices that provide services for the UE, and the configuration information of one network slice includes one of the following items: the priority of the network slice, the rated rate of the network slice, The resource ratio of the network slice or the delay indication information of the network slice; the configuration information of the logical channel includes the respective priorities of the multiple logical channels of the UE and the respective PBRs of the multiple logical channels.

It should be understood that in the above network slice configuration information, the priority of network slices is an indicator that reflects the requirements of network slices on transmission rate or delay. High, that is, high rate or low latency is required; the rated rate of a network slice is the ideal rate corresponding to the network slice or the target rate signed with the operator (for example, the rated rate of network slice 1 is 50Mbit/s); network slice resources The proportion refers to the proportion of resources occupied by each network slice (for example, for 3 network slices, the resources of network slice 1 account for 50%, the resources of network slice 2 account for 30%, and the resources of network slice 3 account for ratio of 20%); the delay indication information of the network slice is used to indicate the delay of obtaining the network slice and allocate resources to the network slice according to the delay of the network slice, and the delay of the network slice refers to the delay of the network slice from the upper The delay between the next scheduling and this scheduling.

Similarly, the priority of the logical channel in the above-mentioned logical channel configuration information may be an indicator that reflects the requirements of the logical channel on the rate or delay, etc., which will not be described in detail here.

It should be noted that, the embodiment of the present invention does not specifically limit the priority size corresponding to the numerical value of the priority (including the priority of the network slice and the priority of the logical channel). Specifically, the higher the priority value, the higher the priority (for example, the priority value of network slice 1 is 1, the priority value of network slice 2 is 2, and the priority value of network slice 2 is higher than that of network slice 2 1 priority), the smaller the priority value, the higher the priority (for example, the priority value of network slice 1 is 1, the priority value of network slice 2 is 2, and the priority value of network slice 1 is 1). higher than the priority of network slice 2).

S102. The network device sends the network slice configuration information and the logical channel configuration information to the UE.

The network slice configuration information and the logical channel configuration information are used by the UE to allocate resources for one or more logical channels of the UE.

Optionally, the network device configures (ie sends) the network slice configuration information and the logical channel configuration information for the UE through radio resource control (radio resource control, RRC) signaling.

S103: The UE receives the network slice configuration information and the logical channel configuration information sent by the network device.

S104, the UE allocates resources for one or more logical channels of the UE from the resources configured for the UE by the network device according to the logical channel configuration information.

With reference to the description of the above embodiments, it should be understood that the logical channel configuration information includes the respective priorities of the multiple logical channels of the UE and the respective PBRs of the multiple logical channels. The respective PBR of each logical channel allocates resources for one or more of its logical channels.

With reference to FIG. 5, as shown in FIG. 6, in an implementation manner, the above S104 specifically includes S104a-S104b:

S104a, the UE determines one or more logical channels that satisfy a preset condition among the multiple logical channels of the UE.

The preset condition is that the number of tokens that can be used in the current token bucket of the logical channel is greater than or equal to zero.

It can be understood that, in the multiple logical channels of the UE, each logical channel corresponds to a variable, that is, the number of tokens that can be used in the current token bucket of the logical channel (hereinafter represented by Bj of the logical channel).

Exemplarily, assuming that among the five logical channels shown in FIG. 2, Bj of logical channel 2, logical channel 3 and logical channel 5 is greater than or equal to zero, and Bj of logical channel 1 and logical channel 4 is less than zero, the UE can determine the logical Channel 2, logical channel 3, and logical channel 5 are the above-mentioned logical channels that satisfy the preset conditions.

S104b, the UE allocates resources to the one or more logical channels according to the respective priorities of the one or more logical channels and the respective PBRs of the one or more logical channels.

In this embodiment of the present invention, the UE allocates resources that satisfy its PBR to the one or more logical channels according to the respective priorities of the one or more logical channels from high to low.

Combined with the example in the above S104a, it is assumed that the priorities of the five logical channels are logical channel 1, logical channel 2, logical channel 3, logical channel 4, and logical channel 5 in order from high to low, and the above-mentioned preset conditions (that is, Bj greater than or equal to zero) logical channels are logical channel 2, logical channel 3 and logical channel 5, wherein the PBR of logical channel 2 is 20Mbit/s, the PBR of logical channel 3 is 10Mbit/s, and the PBR of logical channel 5 is 20Mbit/s Assuming that the size of the resource to be allocated is 100Mbit, the UE allocates 20Mbit, 10Mbit and 20Mbit resources to logical channel 2, logical channel 3 and logical channel 5 in descending order of logical channel priority.

It should be understood that at the initial stage of the establishment of a logical channel, Bj of a logical channel = 0 (that is, the initialization value); the UE will add a PBR of the logical channel to the logical channel in each resource update period (the resource update period is T). The corresponding resource size, and lasts for multiple resource update cycles.

When the UE allocates resources for the logical channel this time, it first needs to update the Bj of the logical channel to obtain Bj', and then determine whether to allocate resources for the logical channel according to the Bj' (that is, allocate resources for the logical channel with Bj' greater than or equal to zero); Then, after allocating resources to the logical channel, update Bj' to obtain Bj", and use the updated Bj" as the Bj of the logical channel when resources are allocated next time.

Here, for a logical channel, the method of updating the Bj of the logical channel to obtain Bj' is: Bj'=PBR*T+Bj, where T is used to represent the interval from the last update of Bj to the current update of Bj; update The method for obtaining Bj" from Bj' of the logical channel is: Bj"=Bj'-R, and R represents the size of the resource allocated to the logical channel by the UE this time (the size of the resource can also be made by using a service data unit (service data unit). , SDU) packet size is characterized).

It can be understood that each logical channel also has its corresponding token bucket, and the capacity of the token bucket represents the maximum amount of resources currently possessed by the logical channel. In this embodiment of the present invention, the Bj of the logical channel should be less than or equal to The capacity of the token bucket of the logical channel, wherein the capacity of the token bucket of a logical channel is equal to the product of the PBR of the logical channel and the bucket size duration (BSD) of the logical channel (that is, the token The capacity of the bucket is equal to PBR*BSD).

Exemplarily, assuming that the initialization Bj of the logical channel 1 is 0, before allocating resources to the logical channel 1 for the first time, the Bj of the logical channel 1 has been updated to Bj', according to the above update formula, Bj'=40Mbit (assuming the above T=4, PBR=10); when resources are allocated to the logical channel 1 for the first time, the logical channel 1 is allocated 140Mbit (ie R=140) resources, then the Bj' of the logical channel 1 is updated at this time Bj", where Bj"=-100Mbit; when allocating resources for the logical channel 1 for the second time, the Bj" (ie -100Mbit) is used as the logical channel 1 when resources are allocated for the logical channel 1 for the second time. Bj.

It should be understood that before allocating resources to logical channel 1 for the second time, the Bj of logical channel 1 is updated from Bj to Bj' again through the above update formula. It is assumed that the resource update period, that is, the PBR of logical channel 1 remains unchanged (that is, T= 4, PBR=10Mbit/s), then Bj'=-100Mbit+40Mbit=-60Mbit; at this time, Bj' is less than zero, indicating that the logical channel 1 was allocated too many resources when it was allocated for the first time, and in the second When resources are allocated for the second time, the embodiments of the present invention give priority to allocating resources to other logical channels (ie, logical channels whose Bj is greater than or equal to zero), which improves the rationality of resource allocation.

In the embodiment of the present invention, after the above-mentioned UE allocates resources to the first one or more logical channels of the UE, the following S105 is performed:

S105. In the case that there are remaining resources in the resources configured by the network device for the UE, the UE allocates resources for one or more logical channels of the UE from the remaining resources according to the network slice configuration information.

For ease of description, in the following embodiments, after the above S104 is completed, the remaining resources (ie the remaining resources in S105 ) in the resources configured by the network device for the UE are referred to as the first remaining resources.

With reference to the description of the above embodiments, it should be understood that after the UE allocates resources for one or more logical channels according to its logical channel configuration information, if there are still remaining resources (that is, the first remaining resources, for example, the first remaining resources) in the resources allocated by the network device for the UE The resource to be allocated in the example in S104b above is 100Mbit, 50Mbit resources have been allocated in S104b, and 50Mbit resources are left), then the UE allocates the first remaining resources to one or more of the UE according to the network slice configuration information. logical channel.

With reference to FIG. 6, as shown in FIG. 7, in an implementation manner, when the network slice configuration information is the priority of the network slice, S105 specifically includes S105a:

S105a, the UE allocates the remaining resources to one or more logical channels of the UE according to the priorities of the multiple network slices and the priorities of the multiple logical channels.

In this embodiment of the present invention, the UE determines the order of resource allocation according to the priorities of multiple network slices (that is, determines to allocate resources to network slices with high priority first, and then allocate resources to network slices with low priority), and allocate resources to network slices. The resource specifically refers to the amount of resources required by the priority of the logical channels included in the network slice and the respective logical channels (it can be understood that the buffer of each logical channel has the required amount of resources cached) is the One or more logical channels contained in a network slice allocate resources.

With reference to Fig. 2, it is assumed that the priority of network slice 2 is higher than that of network slice 1. At this time, the UE allocates the first remaining resources to network slice 2 first, and then allocates the remaining resources to network slice 1 until the first remaining resource is allocated to network slice 1. 1. The remaining resources are allocated. The above-mentioned allocating resources for the network slice 2 from the first remaining resources specifically includes: according to the priority of the logical channels in the network slice 2, one or more of the logical channels (including the logical channel 4 and the logical channel 5) included in the network slice 2 are Logical channel allocation resources, because in network slice 2, the priority of logical channel 4 is higher than the priority of logical channel 5, so the UE can first allocate resources for logical channel 4 in network slice 2, and then allocate resources for this logical channel 4 After the resources are allocated, if there are remaining resources, allocate resources to logical channel 5, so that the UE completes the resource allocation to network slice 2. After the UE allocates resources to the network slice 2, if there are remaining resources, then The logical channel included in the network slice 1 allocates resources. The method for the UE to allocate resources to the network slice 1 is similar to the method for the UE to allocate resources to the network slice 2, and details are not described here.

In one case, after the above S104, when the amount of the first remaining resources is less than or equal to the amount of resources required by the logical channel with the highest priority in the network slice with the highest priority, the UE shall use all the first remaining resources Assigned to the highest priority logical channel. Exemplarily, in another assumption, if the above-mentioned logical channel 4 requires 50Mbit resources, the UE allocates all the first remaining resources (ie, the 50Mbit remaining resources) to the logical channel 4.

In the embodiment of the present invention, the network device configures the priority of the network slice for the UE, so that the UE can allocate resources to the logical channel of the UE in combination with the priority of the network slice, thereby improving the rationality of resource allocation.

With reference to FIG. 6, as shown in FIG. 8, in an implementation manner, when the network slice configuration information is the rated rate of the network slice, S105 specifically includes S105b:

S105b, the UE allocates resources for one or more logical channels of the UE from the remaining resources according to the rated rates of the multiple network slices and the priorities of the multiple logical channels.

With reference to the description of the above embodiments, it should be understood that each network slice in the multiple network slices of the UE corresponds to a rated rate, and the rated rate is the ideal rate corresponding to the network slice or the target rate signed with the operator. The present invention implements In an example, the rated rate of a network slice may be represented by a slice bit rate (SBR).

In this embodiment of the present invention, the UE determines the sequence of resource allocation according to the rated rates of multiple network slices (that is, determines to allocate resources to network slices with a high rated rate first, and then allocate resources to network slices with a low rated rate), and allocate resources to network slices. The resource specifically refers to allocating resources to one or more logical channels included in the network slice according to the priority of the logical channels of the network slice and the resource amount required by each of the logical channels.

It can be understood that the UE can allocate resources for the logical channels included in the multiple network slices from the remaining resources (that is, the first remaining resources) according to the rated rates of the multiple network slices in descending order. In this way, priority can be guaranteed. Network slices with high rate requirements are allocated to resources. It is also possible to allocate resources from the remaining resources (that is, the first remaining resources) to the logical channels included in the multiple network slices according to the rated rates of the multiple network slices in ascending order, so that more network slices ( (or logical channel) are allocated to appropriate resources, and the specific allocation manner is determined according to actual requirements, which is not specifically limited in this embodiment of the present invention.

In the following, the UE allocates resources to one or more logical channels in descending order of the rated rates of multiple network slices (that is, the UE allocates resources to the network slices with a high rated rate first, and then allocates resources to the network slices with a small rated rate. To allocate resources), specifically, taking a network slice as an example, the UE first determines the target allocation resource amount of the network slice, and the target allocation resource amount is equal to the resource amount corresponding to the rated rate of the network slice and the resource amount that has been allocated to the network slice The difference value of , where the amount of resources that have been allocated to the network slice is equal to the sum of the resources that have been allocated to multiple logical channels included in the network slice; then the UE determines whether the amount of resources actually required by the network slice is less than the target allocation of the network slice. The amount of resources, where the actual amount of resources required by the network slice is equal to the sum of the resources required by multiple logical channels included in the network slice; if the actual amount of resources required by the network slice is less than the target resource allocation of the network slice, the UE only Allocate the actual required amount of resources to the network slice; otherwise, the UE allocates its corresponding target resource allocation to the network slice.

Exemplarily, with reference to FIG. 2 and the examples in S104b above, it is assumed that the rated rate of network slice 1 is 50 Mbit/s, and the rated rate of network slice 2 is 30 Mbit/s. In this way, the UE preferentially allocates resources for network slice 1, and then allocates resources for network slice 1. After network slice 1 allocates resources, if there are remaining resources, it is allocated to network slice 2. Assuming that the allocated resources of logical channel 1, logical channel 2 and logical channel 3 in network slice 1 are 0Mbit, 10Mbit and 20Mbit, it can be known that the target resource allocation of network slice 1 is 20Mbit. It is also assumed that the actual amount of resources required by network slice 1 is 10 Mbit (that is, the sum of the resources required by logical channel 1, logical channel 2 and logical channel 3 in network slice 1 is 10 Mbit). (10Mbit) is less than the target allocation resource amount (20Mbit) of the network slice 1, then the UE allocates 10Mbit resources in the first remaining resources (that is, the 50Mbit resources) to the network slice 1. Specifically, in the network slice 1, The UE allocates resources according to the priorities of multiple logical channels (ie, logical channel 1, logical channel 2, and logical channel 3) in the network slice 1 and the respective resource amounts required by the multiple logical channels; If the amount of resources is 20Mbit, the UE allocates 20Mbit resources in the first remaining resources to network slice 1.

Similarly, if there are remaining resources after allocating resources for the above network slice 1, resources are allocated to multiple logical channels of network slice 2 (ie, logical channel 4 and logical channel 5). Specifically, the UE is network slice 2. The method for allocating resources for the multiple logical channels of the above is similar to the above-mentioned method for the UE to allocate resources for the multiple logical channels of the network slice 1, and will not be repeated here.

With reference to the description of the foregoing embodiments, it should be understood that after the first remaining resources are allocated to the foregoing network slice 1 and network slice 2 according to the rated rate of the network slice and the priority of the logical channel (that is, after S105b), there may be remaining resources. (hereinafter referred to as the second remaining resources), at this time, the UE may allocate resources for one or more logical channels of the UE from the second remaining resources according to the logical channel priority of the UE. At this time, the network slice does not need to be considered. configuration information.

Exemplarily, in combination with the above example, after the UE allocates 20 Mbit of the first remaining resource to network slice 1 and allocates 10 Mbit of the first remaining resource to network slice 2, there is still a second remaining resource of 30 Mbit, then The UE allocates the second remaining resources to one or more logical channels according to the priorities of the five logical channels of the UE and the resource amounts required by the five logical channels. Specifically, the UE allocates resources to logical channel 1 first. , if the amount of resources required by the logical channel 1 at the moment is 0, the UE continues to allocate resources for the logical channel 2, and so on, until the second remaining resources are allocated.

In this embodiment of the present invention, the UE allocates resources to the logical channels included in the plurality of network slices from the remaining resources according to the rated rates of the plurality of network slices in descending order (that is, the network slices with higher rated rates are preferentially allocated resources). , and then allocate resources to network slices with a smaller rated rate), which can ensure the transmission rate of network slices with a higher rated rate and improve the user experience of large customers (or customers who have higher requirements for the transmission rate of network slices).

Similarly, the method that the UE allocates resources for the logical channels included in the multiple network slices from the remaining resources in the order of the rated rates of the multiple network slices from small to large is the same as the above-mentioned method of the UE according to the rated rates of the multiple network slices from the largest to the largest. The method of allocating resources to the logical channels included in the multiple network slices from the remaining resources in the smallest order is similar, and details are not described here. The UE allocates resources to the logical channels included in the multiple network slices from the remaining resources according to the rated rates of the multiple network slices in ascending order (that is, the network slices with the lower rated rates are allocated resources first, and then the network slices with the higher rated rates are allocated resources. In the case of more network slices, the transmission rate of more network slices can be guaranteed, and the transmission practicability of network slices can be improved.

With reference to FIG. 6, as shown in FIG. 9, in an implementation manner, when the network slice configuration information is the resource ratio of the network slice, S105 specifically includes S105c:

S105c, the UE allocates resources to one or more logical channels of the UE from the remaining resources according to the resource ratio of the multiple network slices and the priorities of the multiple logical channels.

With reference to the description of the foregoing embodiments, it should be understood that the resource ratio of a network slice refers to the ratio of resources occupied by each network slice. Specifically, taking a network slice as an example, the UE first determines the amount of resources to be allocated for the network slice, and the amount of resources to be allocated is equal to the product of the remaining resources (ie, the first remaining resources) and the resource ratio of the network slice; then the UE determines Whether the amount of resources actually required by the network slice is less than the amount of resources that should be allocated for the network slice, where the amount of resources actually required by the network slice is equal to the amount of resources required by the multiple logical channels included in the network slice (it is understandable that each logical The buffer of the channel is buffered with the sum of the required resources); if the actual required resources of the network slice are less than the allocated resources of the network slice, the UE only allocates the actual required resources for the network slice; otherwise , the UE allocates the corresponding amount of resources to be allocated for the network slice.

Exemplarily, with reference to FIG. 2 and the examples in S104b above, it is assumed that the resource ratio of network slice 1 is 50%, and the resource ratio of network slice 2 is 30%. The amount of resources to be allocated is 25Mbit, and the amount of resources to be allocated for network slice 2 is 15Mbit. It is also assumed that the actual amount of resources required by network slice 1 is 20Mbit (that is, the sum of the resources required by logical channel 1, logical channel 2 and logical channel 3 in network slice 1 is 20Mbit). (20Mbit) is less than the amount of resources to be allocated (25Mbit) of the network slice 1, then the UE allocates 20Mbit resources in the first remaining resources (that is, the 50Mbit resources) to the network slice 1. Specifically, in the network slice 1, The UE allocates resources according to the priorities of multiple logical channels (ie, logical channel 1, logical channel 2, and logical channel 3) in the network slice 1 and the respective resource amounts required by the multiple logical channels; If the resource amount is 25Mbit, the UE allocates 25Mbit resources in the first remaining resources to network slice 1.

Similarly, if there are remaining resources after allocating resources for the above network slice 1, resources are allocated to multiple logical channels of network slice 2 (ie, logical channel 4 and logical channel 5). Specifically, the UE is network slice 2. The method for allocating resources for the multiple logical channels of the above is similar to the above-mentioned method for the UE to allocate resources for the multiple logical channels of the network slice 1, and will not be repeated here.

With reference to the description of the foregoing embodiments, it should be understood that after the first remaining resources are allocated to the foregoing network slice 1 and network slice 2 according to the resource ratio of the network slice and the priority of the logical channel (that is, after S105c), there may be remaining resources. resource (hereinafter referred to as the second remaining resource), at this time, the UE can allocate resources for one or more logical channels of the UE from the second remaining resource according to the priority of the logical channel of the UE. configuration information.

Exemplarily, in combination with the above example, after the UE allocates 25Mbit resources in the first remaining resources to network slice 1, and allocates 15Mbit resources in the first remaining resources to network slice 2, there is still a third 10Mbit resource. remaining resources, then the UE allocates the second remaining resources to one or more logical channels according to the priorities of the five logical channels of the UE and the amount of resources required by the five logical channels. Channel 1 allocates resources. If the amount of resources required by the logical channel 1 at this moment is 10Mbit, the UE can allocate all the second remaining resources of the 10Mbit to the logical channel 1; if the amount of resources required by the logical channel 1 at the moment is 0 , the UE continues to allocate resources for logical channel 2, and so on, until the second remaining resources are allocated.

In the embodiment of the present invention, the network device configures the resource ratio of the network slice for the UE, so that the UE can allocate resources for the logical channel of the UE in combination with the resource ratio of the network slice, thereby improving the rationality of resource allocation.

With reference to Fig. 6, as shown in Fig. 10, in an implementation manner, when the network slice configuration information is the delay indication information of the network slice, S105 specifically includes S105d-S105e:

S105d, the UE acquires the delays of multiple network slices according to the delay indication information of the network slices.

With reference to the description of the above embodiments, it should be understood that the delay of one network slice is used to represent the delay between the last scheduling and the current scheduling of the network slice. If the delay of network slice 1 is greater than the delay of network slice 2 , it can be understood that in the process of service data transmission, the time interval for obtaining service data through network slice 1 is greater than the time interval for obtaining service data through network slice 2 .

S105e, the UE allocates the remaining resources to one or more logical channels of the UE according to the delays of the multiple network slices and the priorities of the multiple logical channels.

In this embodiment of the present invention, the UE determines the sequence of resource allocation according to the delays of multiple network slices (that is, first allocates resources to network slices with large delay, and then allocates resources to network slices with small delay), and allocates resources to network slices Specifically, according to the priority of the logical channels contained in the network slice and the amount of resources required by each logical channel (the buffer of each logical channel has the required amount of resources buffered), the network slice contains one or more resources. Multiple logical channels allocate resources.

With reference to Figure 2, it is assumed that the delay of network slice 2 is greater than the delay of network slice 1. At this time, the UE allocates the first remaining resources to network slice 2 first, and if there are remaining resources, it is allocated to network slice 1 until the first remaining resources are allocated to network slice 1. The remaining resources are allocated. The above-mentioned allocating resources for the network slice 2 from the first remaining resources specifically includes: according to the priority of the logical channels in the network slice 2, one or more of the logical channels (including the logical channel 4 and the logical channel 5) included in the network slice 2 are Logical channel allocation resources, because in network slice 2, the priority of logical channel 4 is higher than the priority of logical channel 5, so the UE can first allocate resources for logical channel 4 in network slice 2, and then allocate resources for this logical channel 4 After the resources are allocated, if there are remaining resources, allocate resources to logical channel 5, so that the UE completes the resource allocation to network slice 2. After the UE allocates resources to the network slice 2, if there are remaining resources, then The logical channel included in the network slice 1 allocates resources. The method for the UE to allocate resources to the network slice 1 is similar to the method for the UE to allocate resources to the network slice 2, and details are not described here.

In one case, after the above S104, when the amount of the first remaining resources is less than or equal to the amount of resources required by the logical channel with the highest priority in the network slice with the largest delay, the UE will use all the first remaining resources Assigned to the highest priority logical channel. Exemplarily, in another assumption, if the above-mentioned logical channel 4 requires 50 Mbit resources, the UE allocates all the first remaining resources (ie, the 50 Mbit remaining resources) to the logical channel 4 .

In the embodiment of the present invention, the network device configures the UE with the delay indication information of the network slice, so that the UE can obtain the delay of the network slice, and then allocate resources to the logical channel of the UE in combination with the delay of the network slice, so as to improve the rationality of resource allocation. sex.

In an implementation manner of the embodiment of the present invention, the delay switch state of the network slice may also be set; after receiving the above-mentioned delay indication information of the network slice, the UE may obtain the partial network slice according to the delay indication information of the network slice The delay of the network slice (that is, the network slice whose delay switch status is ON), and then allocate resources to this part of the network slice.

Exemplarily, if the UE obtains the delay of network slice 1 and the delay of network slice 2 according to the delay indication information of three network slices (including network slice 1, network slice 2 and network slice 3) (that is, network slice 1 and the delay switch status of network slice 2 is ON, and the delay switch status of network slice 3 is OFF), then the UE can allocate the above-mentioned first remaining resources to network slice 1 and network slice 2.

In the method and apparatus for resource allocation provided by the embodiments of the present invention, after receiving the network slice configuration information and logical channel configuration information sent by the network device, the UE can allocate one or more logical channels of the UE according to the logical channel configuration information. resource, in the case that there are remaining resources in the resources configured by the network device for the UE, the UE may allocate resources for one or more logical channels of the UE from the remaining resources according to the network slice configuration information. In the process of allocating the remaining resources, resource allocation is performed according to the network slice configuration information, which can ensure the different needs of users for network slices and improve the rationality of resource allocation.
