Detailed Description
In the Long Term Evolution (LTE) era, a wireless network carries different Service flows through Access Point Name (APN)/Quality of Service (QoS) parameters, and the like, and Service scheduling is performed with User Equipment (UE) as a granularity.
The Network Slice is identified by Single Network Slice Selection Assistance Information (S-NSSAI), and is carried throughout the whole life cycle of the Network Slice, both in the process of registering the UE to the corresponding Slice and in the process of session establishment. The wireless finished basic signaling flow and service guarantee mechanism design includes slice selection when a user accesses, a service guarantee mechanism based on QoS and a slice user group, and the like, a terminal reports a slice (S-NSSAI) of interest, a Next generation base station (Next generation NodeB, gNB) selects a proper Access and Mobility Management Function (AMF) for the UE according to a slice list reported by the UE, and a core network configures an allowed slice list (allowed NSSAI) and a Registration Area (Registration Area, RA) to the UE through a Non-Access-layer (NAS) message.
In the fifth generation mobile communication technology (5th generation, 5G) era, network slicing is an important means of "differentiation-oriented services", and can provide customized logic isolation or dedicated networks to provide services for different traffic flows. In order to better meet the requirements of different services, the wireless network side device needs to introduce a scheduling policy with smaller granularity according to the slice.
At present, service guarantee schemes of wireless network side equipment are divided into two types, one is service guarantee based on QoS: the wireless network side equipment deeply optimizes the wireless network from three dimensions of air interface rate, time delay and reliability based on a QoS mechanism, so that qualitative and/or quantitative air interface performance guarantee is realized, the scheduling granularity takes UE as the minimum granularity, and the use of slices is limited. For example, the same terminal has a slice guarantee service and a non-guarantee service or has two slices with different priorities, and different services cannot be differentiated and guaranteed based on the scheduling granularity of the UE.
A plurality of logical channels (logical channels) are multiplexed on the same transport channel (transport channel) in a Media Access Control (MAC) layer of the terminal. UE can only send one MAC Protocol Data Unit (PDU) per Transmission Time Interval (TTI) (without considering the case of space division multiplexing and carrier aggregation), but may need to put a Radio Link Control (RLC) Service Data Unit (SDU) from multiple logical channels on the same MAC PDU. The principle of the current scheduling priority implementation scheme of the wireless network side equipment is as follows: for a plurality of logical channels, the channel priorities (priorities) thereof should be considered according to the different degrees of information importance, taking into account the following relative priorities (in order from high to low):
(1) a MAC Control Element (Control Element) for a Cell-Radio Network Temporary Identifier (C-RNTI) or data from an Uplink-common Control channel (UL-CCCH);
(2) a MAC control element for BSRs other than a "padding (padding) Buffer Status Report (BSR)";
(3) a MAC control element for Power Headroom Report (PHR) or extended PHR;
(4) data from any logical channel in addition to data of UL-CCCH;
(5) MAC control element for "padding BSR".
Currently, the wireless MAC scheduling module generally includes scheduling ordering, resource allocation, and contents of Downlink Control Information (DCI) and the like when performing resource scheduling. When scheduling, firstly, scheduling user ordering of the time slot is required according to a scheduling algorithm, such as polling, Proportional Fair (PF), and the like, then resource allocation is performed according to priority, and finally, DCI is performed and scheduling information and corresponding data are issued. The scheduling priority ranking algorithm is used for ranking by taking UE as a unit, as long as the UE has a high priority of one logic channel, the priority of all data of the UE is promoted and is scheduled together, the UE is used as the unit for allocating resources, if one UE has a plurality of logic channels, the logic channel with low priority is scheduled because the UE queues up ahead, and the high priority resources of other UEs are preempted. Meanwhile, the existing logic channel priority queuing strategy is unchanged, and cannot be adjusted according to the service condition, which easily causes network resource waste. The high flexibility feature of network slices cannot be accommodated.
For example, there are two UEs in the scheduling queue, UE1 has Qos Class Identifier (QCI) 3 and QCI9, and UE2 has QCI4 and QCI8, and according to the logical channel scheduling sorting rule, the sequence should be: QCI3, QCI4, QCI8, QCI9, resulting in a queuing order for the UE of: UE1, UE 2; when the resource allocation is allocated according to the UE, if the flow control algorithm is started, the remaining resources are finally allocated to the QCI9 after all guaranteed rates are met, and the QCI8 allocation of the UE2 is uneven.

Referring to fig. 1, an embodiment of the present invention provides a resource allocation method, where an execution subject of the method may be a network side device, and the method includes the specific steps of: step 101 and step 102.
Step 101: acquiring the priority of a logical channel of scheduled UE, wherein the logical channel and a network slice have a corresponding mapping relation;
step 102: and allocating resources for the logic channel of the scheduled UE according to the priority of the logic channel.
In some embodiments, the method further comprises:
configuring a mapping relationship between the logical channel and a network slice, wherein the mapping relationship comprises: a correspondence of single network slice selection assistance information and quality of service class identification or 5G quality of service indication.
In some embodiments, before acquiring the priority of the logical channel of the scheduled UE, the method further comprises: and taking the logical channels as units, and carrying out priority ordering on the logical channels of different scheduled UEs.
In some embodiments, after allocating resources for the logical channels of the scheduled UEs, the method further comprises:
and sending indication information (such as downlink control information) which indicates that the combined scheduling is carried out on the logical channels belonging to the same scheduled UE.
In the embodiment shown in fig. 1, the MAC layer adds a mapping relationship between the S-NSSAI identifier of the network slice and the QCI/5QI, and thus completes mapping between the slice and the logical channel. For example, the logical channels are sorted by taking the logical channels as a unit, the logical channels of different users are sorted by priority, the logical channels are allocated by taking the logical channels as a unit during resource allocation, and the logical channels belonging to the same UE are merged and scheduled after the allocation is finished. The final scheduling is still performed with the granularity of users, so that the expenditure can be saved. If one UE has a plurality of logic channels entering the scheduling and resource allocation queue, the merged scheduling is needed, that is, one UE issues one downlink control message, at this time, the resource can be prevented from being used by the logic channel with low priority, and the resource fairness is ensured.
For example, there are two users in the scheduling queue, UE1 has QCI3 and QCI9, UE2 has QCI4 and QCI8, and according to the logical channel scheduling sorting rule, the order should be: QCI3, QCI4, QCI8, and QCI9, and the queuing order is output to the resource allocation module; and the resources are distributed according to users, if the flow control algorithm is started, the remaining resources are distributed to the QCI8 after all guaranteed rates are met, and the fairness of resource distribution is guaranteed.

In the embodiment shown in fig. 2, when the terminal groups MAC PDUs, in addition to data of UL-CCCH, data from any logical channel should be sorted according to different priorities of network slices, and it is preferentially ensured that data with high priority is preferentially scheduled. That is, when data arrives at the data queue, it needs to be compared with the priority of the existing data, and if the subsequent data comes from a slice with high priority, it needs to be ranked ahead of a slice with low priority.
