- Question 1 Considering the scenario of the first delay budget (such as PSDB), it should also be the delay budget in 5GS. Because the number of data packets included in the first delay budget is different. So the CN Packet Set PDB of each packet set is different. RAN cannot simply be understood as subtracting the first delay budget from the empirical value of a public CN PDU Set delay to obtain the first access network delay budget.
- the first delay budget such as PSDB
- the value corresponding to the second core network delay information is a common empirical value, applicable to all data packet sets.
- the value corresponding to the second core network delay information is based on T2 -T1 (the delay overhead between UPF and RAN for the first data packet of the data packet set) is determined, and T2-T1 is the delay between UPF and RAN for the first data packet of each data packet set. overhead.
- UPF needs to add T1 to the first packet in the packet set, and the RAN records the above T2.
- the second access network delay budget is determined.
- the uplink CN PDU Set delay is related to the number of PDUs in the PDU Set. The greater the number of PDUs in the PDU Set, the longer the CN PDU Set delay.
- the uplink PDU Set generated on the UE arrives at the UE modem at the same time and is waiting for scheduling, there is no problem that the PDUs in the PDU Set arrive one after another. Then the UE can quickly determine the PS Size (number of packets or bits) in the PDU Set. The UE informs the RAN of the PS Size.
- the first uplink access network delay budget the first delay budget - the value corresponding to the second core network delay. In order to ensure that the last packet of the PS is transmitted between the RAN and UPF, enough delay budget is reserved, that is, the last It is not difficult to understand that one package is never late, and the last package is never late. Other PS packages are not late either, ultimately achieving the goal of ensuring the first delay budget.
- RAN retrieves the uplink data based on PS Size and the first access network delay budget (such as AN PSDB).
- the RAN allocates time and frequency resources, but it is the UE that decides which data to send first.
- Existing UEs send data according to the priority of logical channels.
- a logical channel can contain multiple packet sets. Additionally, the UE shall determine the sending priority of uplink data based on the first access network delay budget.
- the UE directly obtains the first access network delay budget from the RAN or CN;
- the UE obtains the first delay budget (such as PSDB) from the CN and the second core network delay budget (such as CN PDB) from the RAN.
- the UE obtains the first delay budget and the second core network delay budget from the RAN.
- the delay budget calculates the first access network delay budget by itself (such as PSDB-CN PDB);
- the UE itself determines the first delay budget and obtains the CN PDB second core network delay budget (such as CN PDB) from the RAN.
- the UE determines the first delay budget and the second core network delay budget based on the first delay budget and the second core network delay budget. Calculate the first access network delay budget yourself (such as PSDB-CN PDB).
- the first delay budget of each data packet set may be the same or different. If it is the first delay budget of the per packet set, then for downlink, it can only be carried by inbound signaling, such as GTP-U; for uplink, the UE can only send the first delay budget to the RAN.

本申请实施例中,存在以下问题需要解决:
问题1:考虑到第一时延预算(比如PSDB)的场景,同样也应该是5GS中的时延预算。由于第一时延预算中包含的数据包的数量不同。所以每个数据包集合的CN Packet Set PDB是不同的。RAN不能简单地理解为将第一时延预算减去一个公共的CN PDU Set delay的经验值来得出第一接入网时延预算。
对于下行数据:第一接入网时延预算(如AN PSDB)=第一时延预算-第二核心网时延信息对应的值(如第二核心网时延或第二核心网时延预算)。一种实施方式中,第二核心网时延信息对应的值是一个公共的经验值,适用于所有的数据包集合,另一种实施方式中第二核心网时延信息对应的值是根据T2-T1(数据包集合的第一个数据包在UPF与RAN间的时延开销)确定的,所述T2-T1是每个数据包集合的第一个数据包在UPF与RAN间的时延开销。该实现方式中,UPF需要为数据包集合中的第一个数据包加上T1,并由RAN记录上述T2。可选地,对于数据包集合的任意个一数据包或最后一个数据包,确定第二接入网时延预算。
对于上行数据:上行的CN PDU Set delay与PDU Set中PDU数量有关。PDU Set中的PDU数量越多,CN PDU Set delay越长。
由于UE上产生的上行PDU Set是同时到达UE modem等待调度的,所以不存在PDU Set中的PDU先后到达的问题,那么UE可以快速地确定PDU Set中的PS Size(包数量或bit数量)。UE将所述PS Size告知RAN。上行第一接入网时延预算=第一时延预算-第二核心网时延对应的值,为了保证PS的最后一个包在RAN与UPF间传输的预留足够的时延预算,即最后一个包不迟到,不难理解,最后一个包不迟到。PS的其他包也不迟到,最终达到保障第一时延预算的目的。RAN根据PS Size和第一接入网时延预算(比如AN PSDB)来调取所述上行数据。
问题2:现有的调度是RAN分配时频资源,但优先发送哪些数据是UE来决定的。现有的UE的是根据逻辑信道的优先级发送数据。一个逻辑信道中可以包含多个数据包集合。额外地,UE要根据第一接入网时延预算来决定上行数据的发送优先级。
在一种实现方式中,UE从RAN或CN直接获取第一接入网时延预算;
在另一种实现方式中,UE从CN获得第一时延预算(如PSDB),从RAN获得第二核心网时延预算(如CN PDB),UE根据第一时延预算和第二核心网时延预算自己计算第一接入网时延预算(如PSDB-CN PDB);
在又一种实现方式中,UE本身确定第一时延预算,从RAN获得CN PDB第二核心网时延预算(如CN PDB),UE根据第一时延预算和第二核心网时延预算自己计算第一接入网时延预算(如PSDB-CN PDB)。
问题3:RAN上的第一时延预算从哪里来。
一个DRB中可以存在多个数据包集合,每个数据包集合的第一时延预算可以相同或不同。如果是per数据包集合的第一时延预算,那么对下行,只能是inbound signalling携带,比如GTP-U;对上行,只能是UE向RAN发送所述第一时延预算。
