Definitions
- the present invention relates to data packet transmission, and more particularly, to a closed-loop capacity scheduling method for transmitting uplink packets from a mobile station to a base station.
- the uplink capacity of a cell is managed by a distribution scheme, and mobile stations are allowed to transmit up to the maximum capacity controlled by the radio network controller.
- the control of uplink noise uses a low-speed statistical multiplexing control in which the radio network controller controls the maximum transmission rate of the mobile station. Therefore, the fluctuation of noise rise is large and a large noise rise margin is required, which results in a loss of uplink capacity.
- a higher priority data packet is transmitted to a lower priority data bucket destination.
- base station 13 exchanges capacity request 110 on the uplink and capacity allocation 120 on the downlink.
- Capacity scheduling refers to mobile stations transmitting data buckets using shared uplink capacity 14. In other words, the transmission speed and transmission time are controlled.
- the scheduling timing 140 is the timing at which the capacity scheduling is determined, and this determination is valid until the next scheduling timing.

For example, assume that a specially paid business user 11 in Figure 1 should be given higher priority than a more economical home user 1 2. Thus, when multiple priorities coexist in a network, the capacity is allocated so that higher priority bucket transmissions are assigned before lower priority bucket transmissions. Capacity should be used effectively.
- a third object of the present invention is to provide a capacity scheduling that supports bucket transmissions having a plurality of priorities.
- a fourth object of the present invention is to provide capacity scheduling that supports bucket transmissions with multiple QoS and multiple priorities.
- uplink bucket scheduling if capacity scheduling is fast enough to follow changes in the wireless channel environment, wireless resources can be used effectively. This is made possible by scheduling closer to the radio channel. The improvement in capacity is achieved by flattening the rapid fluctuations of the uplink noise rise so that the noise rise margin can be further reduced.

- a second advantage of the present invention is that both the mobile station and the base station recognize the QoS of the data flow in addition to the priority.
- the current rate allocation method in WC DMA only considers data flow priority when distributing uplink capacity among multiple uplink data flows. In this application, the required flow capacity can be divided into a minimum QoS and the rest of the capacity, so that the minimum QoS capacity of the lower priority data flow is reduced to the higher priority data flow. Additional flow QoS Compensated before capacity.
- a third advantage of the present invention is that the mobile station can adjust the capacity request and capacity allocation taking into account the QoS and priority of the data flow. Coordination of capacity requests is crucial when the total required capacity is insufficient for a given uplink transmission power. Adjustment of capacity allocation is required when scheduling delay occurs. This application proposes adjustments that take into account the QoS and priority, so that additional capacity for flows with lower priorities can be adjusted before the minimum QoS capacity with higher priority.

- the implementation of the FCC for GBR traffic classes is shown in Figure 4.
- the QoS parameters for the GBR traffic class are maximum capacity (MC) and compensation capacity (GC).
- MC maximum capacity

- ABR is a traffic class for which the allocated capacity is determined based on the available percentage of capacity.
- the QoS parameters for the ABR traffic class are maximum capacity (MC) and minimum capacity (MNC).
- MNC is the minimum capacity for transmitting small data buckets such as TCP and TCK at an arbitrary timing, while MC is the upper limit of allowable capacity.
- the implementation method of ABR ⁇ is the same as the case where the QoS parameter of the compensation capacity (GC) is set to zero in the case of 681 ⁇ FCC. In this case, since there is no QoS request for the capacity scheduler, as much capacity as possible can be allocated.

- FIG. 5 shows an implementation example of the TBR FCC.
- Retransmitted data has a higher priority than new transmitted data. Therefore, AC is first allocated to the retransmission data, and then the remaining capacity is allocated to the new transmission data (51 in Fig. 5).
- the difference between the current moving average (MAAC) of the assigned capacity and TC (52) is first calculated. Then calculate the required capacity that satisfies the TC (53, 530). Then, capacity allocation is performed so that the allocation capacity (ACNT) does not exceed the MC and queue size (QC) 54.
- the MAAC is updated by taking a moving average using the newly calculated ACNT (55), and the capacity request (CR) is finally calculated to satisfy the TC (56).
- Exponential tuning may be used to speed up convergence (530).
- Non-schedulable data transmission is a background load that is not controlled by the scheduler.
- CS calculates available and schedulable capacity, which is the difference between maximum capacity and non-schedulable capacity.
- the base station Upon receiving a capacity request from a mobile station, the base station performs a capacity request adjustment, as shown in Figure 6 at 602:
- the base station allocates a minimum allowed headroom for the allowed transmit power for each mobile station and then calculates the maximum supportable capacity for each mobile station.
- the minimum allowed transmit power headroom controls interference with other cells in the network.
- the maximum capacity that can be supported at a given minimum allowed transmit power headroom is compared to the total required capacity.
- Maximum capacity capacity that can be supported Starting with the lowest priority flow increase it to be greater than the total required capacity.
- the addition of capacity requests in the order of higher priority flows reduces the Q o S capacity part. If that is not enough, the minimum QoS capacity part of the capacity request is reduced from the lowest priority flow to the highest priority flow. If that is not enough, the retransmission portion of the requested capacity is reduced from the flow with the lowest priority to the flow with the highest priority.
- the base station has a request retransmission capacity (RCRTX), a minimum QoS capacity for each priority level (RCMQ (1) to RC MQ (N)), and an additional QoS capacity for all mobile stations (RCEQ (1 ) To calculate the total amount of RCEQ (N)).
- the base station also calculates, for each mobile station flow, the retransmission capacity, minimum QoS capacity and additional QoS capacity using the flow information and the reported capacity request.
- the base station first allocates a schedulable capacity to the retransmission capacity 61 as shown in FIG. If the total schedulable capacity is not sufficient to satisfy the sum of the requested retransmission capacities, the base station allocates retransmission capacities in order from the highest priority flow to the lowest priority flow. If all of the schedulable capacities are sufficient to satisfy the sum of the requested retransmission capacities, the base station shall start with the highest priority flow 62 and the lowest priority flow 63 in FIG. Allocate the remaining schedulable capacity to the minimum QoS capacity. If this still has enough schedulable capacity, the base station may add the remaining schedule capacity to the additional QoS capacity in order from the highest priority flow 64 to the lowest priority flow 65 in FIG.
- Allocate available capacity Preferably, capacity is distributed among flows belonging to the same priority level in a fair scheduling manner.c Finally, the base station assigns, for each flow of each mobile station, an assigned retransmission capacity, an assigned minimum Calculate total allocated capacity, which is the sum of QoS capacity and additional quota.
- FIG. 7 shows a system configuration including a plurality of mobile stations and one base station, including an uplink and a downlink channel used in the second embodiment.
- FIG. 7 differs from FIG. 2 showing the system configuration in the first embodiment in that CAC in FIG. 2 is not provided.
- the CAM transmitted from the base station is received by the TFCC “215 J. CAM indicates the total allocated capacity allocated to each mobile station. Therefore, the TFCC selects a combination of transport formats that is less than the total allocated capacity and less than the maximum power of the mobile station, where the TFCC requests higher priority flows.
- the transport format combination is determined so that the quality is satisfied before the required quality of the low-priority flow, and the TFCC then calculates a TFC I indicating the selected transport format combination.
- information about the selected transport format combination is sent to the FCC.
- the FCC extracts the information on the capacity allocated to each data flow from the information on the selected combination of transport formats, and obtains the flow request Q. Calculates the required uplink capacity of the data flow based on the data and generates a capacity request (CR). After that, the CR is transmitted to the CRC, multiplexed in the same procedure as in the first embodiment, and transmitted as a capacity request message (CRM) to the capacity scheduler 1 (CS) in the base station.
- CRM capacity request message
- the CS in the second embodiment calculates the assigned capacity of each flow in the same procedure as the CS in the first embodiment described with reference to FIG.
