Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In order to solve the problems that the utilization rate of isolation resources is low and the Service Quality of a terminal cannot be guaranteed when the Service load of a network slice is large in a resource allocation mode of the network slice in the prior art, embodiments of the present invention provide a Media Access Control (MAC) multiplexing method, which ensures that the isolation resources with high priority can be used by a terminal served by a specific network slice, that is, can be used by other terminals when the load of the network slice is allowed to be low, and simultaneously still ensures the requirement of Quality of Service (QoS) of the slice Service terminal when the network switching load is high and the isolation resources are not enough, by a method of multiplexing the logical channel priority and the MAC.

and S120, multiplexing the medium access control layer service data unit (MAC SDU) data on the target logical channel into medium access control layer protocol data unit (MAC PDU) data according to the parameter values.
By adopting the MAC multiplexing method in this embodiment, by configuring parameter values corresponding to different frequency resources for the multiplexing priority parameter of the same logical channel, when corresponding to different frequency resources, the adopted logical channel priority is different from the MAC multiplexing method according to the different parameter values configured for the multiplexing priority parameter, and on the isolation resource corresponding to a specific network slice service, the corresponding service may share the highest priority, and on other isolation resources, the service may not share the highest priority for transceiving, so that the service may be used by other terminals when the network slice load is low, and meanwhile, when the network switching load is high and the isolation resource is insufficient, the QoS requirement of the slice service terminal is still ensured.
In the MAC multiplexing method according to the embodiment of the present invention, optionally, the multiplexing priority parameter includes at least one of a prioritized bit rate PBR, a Bucket Size Duration (BSD), and a logical channel priority.
In one embodiment, optionally, the number of the parameter values configured for the reuse priority parameter is at least two, where different parameter values correspond to different frequency resources.
By configuring the parameter values of the multiplexing priority parameter corresponding to different frequency resources, the network slice has different priorities when being transmitted by adopting different frequency resources.
In one embodiment, the number of the parameter values configured for the multiplexing priority parameter is one, and the parameter value corresponds to a first frequency resource in all the frequency resources.
By adopting the embodiment, the base station configures one parameter value for one multiplexing priority parameter of the terminal, and the one parameter value corresponds to at least one frequency resource, namely the first frequency resource. According to the configured parameter value, the resource with the first frequency is adopted to have the highest priority in service transmission compared with the commonly used parameter value of the corresponding multiplexing priority parameter of other resource frequencies.
In one embodiment, optionally, the configured parameter values of the multiplexing priority parameter include a first parameter value and a second parameter value, where the first parameter value corresponds to a first frequency resource in all frequency resources, and the second parameter value corresponds to other frequency resources except the first frequency resource.
Optionally, with the configuration, according to the configured first parameter value and the second parameter value, the first frequency resource has the highest priority in service transmission compared with a commonly used parameter value of a corresponding multiplexing priority parameter of other resource frequencies.
Optionally, when the multiplexing priority parameter includes the priority bit rate PBR, the first parameter value of the configured PBR is greater than the second parameter value.
When the multiplexing priority parameter comprises the priority of the logic channel, the first parameter value of the configured priority of the logic channel is smaller than the second parameter value.
When the multiplexing priority parameter includes the BSD, a first parameter value of the configured logical channel priority is greater than a second parameter value.
In one embodiment, optionally, the parameter values include a first parameter value and a third parameter value, where the first parameter value corresponds to a first frequency resource in all frequency resources, and the third parameter value corresponds to all frequency resources.
Optionally, by using the configuration manner, according to the configured first parameter value and the configured third parameter value, the first frequency resource is used to have the highest priority during service transmission compared with the commonly used parameter values of the multiplexing priority parameters corresponding to other resource frequencies.
In this embodiment, optionally, when the multiplexing priority parameter includes the priority bit rate PBR, the first parameter value of the configured PBR is greater than the third parameter value.
And when the multiplexing priority parameter comprises the priority of the logic channel, the first parameter value of the configured priority of the logic channel is smaller than the third parameter value.
When the multiplexing priority parameter includes the BSD, the first parameter value of the configured logical channel priority is larger than the third parameter value.
In one embodiment, the parameter values include a first parameter value, a second parameter value, and a third parameter value, where the first parameter value corresponds to a first frequency resource of all frequency resources, the second parameter value corresponds to other frequency resources except the first frequency resource, and the third parameter value corresponds to all frequency resources.
It should be noted that the first frequency resource is at least one frequency resource.
The MAC multiplexing method according to the embodiment of the invention,
in one embodiment, optionally, the base station configures at least one PBR for the target logical channel of the terminal, that is, configures at least one parameter value corresponding to the PBR, where each parameter value corresponds to at least one frequency resource, that is, is applicable to at least one frequency resource.
The base station configures at least one PBR for the target logical channel, and each PBR corresponds to at least one frequency resource. Each PBR is a specific PBR, and each specific PBR is higher than a general PBR configured on the logical channel, so that the frequency resources corresponding to each configured specific PBR have higher priority than other frequency resources.
Optionally, the at least one PBR configured for the target logical channel by the base station includes a PBR corresponding to the first frequency resource, that is, a specific frequency resource, and also includes a PBR corresponding to another frequency resource except the first frequency resource, that is, a first parameter value and a second parameter value are configured for the PBR, where the first parameter value corresponds to the first frequency resource, the second parameter value corresponds to another frequency resource except the first frequency resource, and the first parameter value is greater than the second parameter value, so that the service of the network slice is transmitted on the first frequency resource with the highest priority.
Optionally, the at least one PBR configured for the target logical channel by the base station includes a PBR corresponding to the first frequency resource, that is, the specific frequency resource, a first parameter value corresponding to the first frequency resource, and a third parameter value corresponding to all the frequency resources, that is, besides the PBR configured for the specific frequency resource, the base station further includes a general PBR, and the general PBR does not distinguish the frequency resources, that is, the PBR requirement that all the frequency resources need to meet is included.
For example, a frequency-specific PBR is configured for the frequency resources 2.6GHz and 3.5GHz (i.e. a first parameter value is configured), and the frequency-specific PBR is used when the uplink data is transmitted on the two frequency resources; the generic PBR (i.e., the third parameter value) is used when the upstream data is transmitted on other frequency resources (e.g., 4.9 GHz).
Optionally, the first parameter value is greater than the third parameter value such that traffic of the network slice is transmitted on the first frequency resource with highest priority.
From the above, it should be noted that, in addition to configuring the specific PBR corresponding to the first frequency resource, the specific logical channel priority and/or the specific BSD may be configured for the first frequency resource, respectively.
By adopting the MAC multiplexing method, for example, for a first frequency resource allocated to a target service, a logical channel corresponding to the target service has the highest logical channel priority on the first frequency resource, and the maximum PBR and BSD are 500 ms; in other frequency resources except the first frequency resource, the priority of the logical channel corresponding to the first frequency resource is the third priority, the PBR is higher, for example, 100Mbps, and the BSD is 300ms, under the configuration, if there is an available uplink resource on the first frequency resource, the service data of the target service is preferentially sent, and only when there is no service data on the logical channel to be sent, other data is sent.
In this embodiment of the present invention, when the configured parameter value of the multiplexing priority parameter includes at least one PBR value of the priority bit rate PBR, and when a target service is transmitted through a first frequency resource, multiplexing MAC SDU data of a MAC service data unit of the target service on the target logical channel into MAC PDU data according to the parameter value corresponding to the frequency resource configured for the multiplexing priority parameter, includes:
determining a maintenance variable B of the target logical channel corresponding to each PBR value at each time unit T (e.g., time interval TTI)jSaid maintenance variable BjThe token bucket is used for indicating the number of tokens to be currently available in the multiplexing token bucket;
maintenance variable B determined according to PBR value corresponding to target resource frequencyjMultiplexing the MAC SDU data of the target service on the target logic channel to the MAC PDU data when the time is more than zero;
each PBR value corresponds to a maintenance variable BjAnd after the data size of the MAC SDU data multiplexed to the MAC PDU data is respectively reduced, executing next logical channel multiplexing when the number of the multiplexed MAC SDUs on the target logical channel meets the transmission requirement of the PBR value corresponding to the first frequency resource.
Optionally, multiplexing the MAC SDU data of the target service on the target logical channel and the MAC SDU data on other logical channels onto the MAC PDU data, including:
and under the condition that the target service is transmitted through the first frequency resource, the priority of the target logic channel is the logic channel priority corresponding to the first frequency resource, and the MAC SDU data on the target logic channel and other logic channels are sequentially packed and multiplexed into MAC PDU data according to the descending order of the logic channel priority.
Optionally, a maintenance variable B corresponding to each PBR value of the target logical channel in each time unit T is determinedjThe method comprises the following steps:
each time unit T passes, the sum of the target logical channel and each PBR value PBRxCorresponding maintenance variable BjSeparately increase PBRxMultiplied by T, wherein PBRxIs the value of the x-th PBR value, where x is the target logical channelSequence number of configured PBR values, PBR of one sequence numberxCorresponding to one frequency resource.
It should be noted that, when performing MAC multiplexing, the UE receives uplink Radio resources from the base station, specifically which logical channels of data can be placed in the allocated uplink resources, and how much data is placed in each logical channel, which are determined by the UE based on Radio Resource Control (RRC) configuration and protocol specification.
A priority field is configured for each logical channel by RRC, and the smaller the value, the higher the priority. In addition, a Prioritized Bit Rate (PBR) and a Buffer Size Duration (BSD) are configured for each logical channel, and the PBR is used to provide a minimum data Rate guarantee for each logical channel, so as to avoid a problem that low-priority logical channel data cannot be transmitted all the time. The BSD and the PBR jointly determine the maximum capacity of the token bucket, that is, the maximum capacity of the token bucket is determined according to PBR × BSD, that is, the total amount of data that can be buffered in the buffer of each logical channel.
In addition, the terminal UE maintains a variable Bj for each logical channel j, where the variable Bj indicates the number of token tokens currently available in the token bucket, and each token corresponds to 1 Byte of data. Bj is initialized to 0 during the establishment of the logical channel, and PBR × TTI token numbers are added for each Transmission Time Interval (TTI). For example, if the PRB is 8kBps, 8kBps 1ms, which is the number of tokens of 8Byte, is injected into the token bucket every TTI. Where the value of Bj cannot exceed the maximum capacity PBR BSD of the token bucket. Taking BSD 500ms as an example, the maximum capacity of the token bucket is 8kBps 500ms 4 kbyte.
As shown in fig. 2, the MAC multiplexing process is usually performed by comparing whether Bj is greater than 0 for each RLC SDU transmitted in logical channel j. And if the Bj is larger than 0, adding the SDU into the MAC PDU, namely multiplexing the SDU into the MAC PDU. The current Bj is then subtracted by the size Tsdu of the SDU and it is determined whether the PBR requirement is met. This is repeated until Bj is less than 0, or the PBR requirement is met, and then the next logical channel is processed.
Therefore, the step of MAC multiplexing typically includes:
determining the value of a variable Bj maintained by each logic channel, and for all logic channels with Bj larger than 0, grouping the logic channels according to the descending order of priority, wherein the radio resources allocated to each logic channel can only meet the requirement of the configured PBR;
for each logical channel, subtracting the size of all MAC SDUs of the corresponding logical channel multiplexed to the MAC PDU in the previous step from the current variable Bj, determining whether the PBR requirement is met, if not, continuing to read the MAC SDU of the current logical channel, judging whether Bj is greater than 0, if Bj is greater than 0, multiplexing the SDU on the logical channel to the MAC PDU, repeating the steps until the variable Bj is less than 0 or the PBR requirement is met, and then processing the next logical channel;
after the two processes are executed, if uplink resources still exist, the remaining resources are allocated to each logical channel according to the logical channel priority regardless of the size of Bj. Only when the data of all the logical channels with high priority are sent and the uplink configuration UL grant is not exhausted, the logical channel with low priority can be served. I.e. when the terminal maximizes the data transmission of the logical channel of high priority.
Based on the above process of MAC multiplexing, with the MAC multiplexing method according to the embodiments of the present invention, when the base station configures at least one parameter value for the multiplexing priority parameter of the target logical channel of the terminal, taking the multiplexing priority parameter including the PBR as an example, the terminal maintains different bjs for different PBRs of the target logical channel.
For example, PBR is the first parameter value PBR1Corresponding to BjCan be represented as Bj,1The method may be applied to a plurality of frequency resources, such as a first frequency resource. PBR is the second parameter value PBRmCorresponding to BjCan be represented as Bj,mMay be applicable to a plurality of frequency resources, such as a second frequency resource; PBR is a third parameter value PBRcommonCorresponding to BjIs Bj,commonAnd the method can be applied to all frequency resources. Wherein the third parameter value PBRcommonLess than the first parameter value PBR1Is also less thanSecond parameter value PBRm。
In the MAC multiplexing process, in each transmission time interval TTI, corresponding to one frequency resource corresponding to BjIncreasing in step PBR × TTI. E.g. corresponding to traffic transmission on a second frequency resource, Bj,mIn step size PBRmX TTI increase, i.e. Bj,m＝Bj,m+PBRm×TTI。
The terminal determines which PBR and possibly other logical channel priority parameters (such as logical channel priority and/or BSD) are based on which PBR and possibly other logical channel priority parameters to perform MAC multiplexing according to the frequency resources to which the available uplink resources belong, and the correspondence between the frequency resources and the PBRs.
Specifically, the MAC multiplexing process may include the following steps:
when the PBR configured for the logical channel includes a parameter value PBR corresponding to a specific first frequency resource xmAnd also includes parameter values PBR corresponding to the universal frequency resources ycommonIf the currently available uplink resource for transmitting the target service is the first frequency resource, the MAC multiplexing includes:
determining a maintenance variable B for the target logical channel corresponding to each PBR valuej；
Maintenance variable B determined according to PBR value corresponding to target resource frequencyjWhen the data is more than zero, multiplexing the MAC SDU data of the target service on the target logic channel to the MAC PDU data;
each PBR value corresponds to a maintenance variable BjAnd after the data size of the MAC SDU data multiplexed to the MAC PDU data is respectively reduced, executing next logical channel multiplexing when the number of the multiplexed MAC SDUs on the target logical channel meets the transmission requirement of the PBR value corresponding to the first frequency resource.
In the above manner, when SDUs in the logical channel are multiplexed to the MAC, all bsj,mThe size of the SDU is reduced, i.e. Bj,m＝Bj,m–TsduWherein T issduIs the size of the SDU. When the PBR evaluation is carried out, only the maximum parameter in the configured PBR parameter values is neededThe values were evaluated. If the maximum parameter value requirement is not met, the data of the logical channel is continuously multiplexed, otherwise, the multiplexing of the logical channel of the next priority is executed.
As shown in connection with fig. 3, the PBR configured for the logical channel includes a parameter value PBR corresponding to a specific first frequency resource xxAnd also parameter values PBR corresponding to other frequency resources yyFor example, according to fig. 3, when the frequency resource of the target service transmission is the first frequency resource x, the process of performing MAC multiplexing on the logical channel j may include:
each transmission unit T, PBRxCorresponding variable BjxIncreasing PBR per Transmission time Interval TTIxX number of tokens for TTI;
in the PBR corresponding to the first frequency resource xxDetermined BjxWhen the PBR value is larger than zero, the maintenance variable corresponding to each PBR value respectively subtracts the data size of the MAC SDU data multiplexed to the MAC PDU data, namely BjxAnd BjyRespectively subtract TsduAnd multiplexing the MAC SDU on the target logical channel in the MAC PDU; then judging that the number of the current available tokens token in the multiplexing token bucket meets the PBR corresponding to the target resource frequency xxWhen the transmission of the value requires, the next logical channel multiplexing is executed; in case of not satisfying PBRxWhen the transmission requirement of the value is met, continuing transmitting SDU data to the target logic channel;
in the PBR corresponding to the first frequency resource xxDetermined BjxAnd if the number of the tokens is not more than zero, determining that no token is available in the token bucket, and not multiplexing SDU data on the target logical channel in the MAC PDU.
