- the present invention relates to uplink data packet transmission in wideband code division multiple access (WCDMA) technology.
- WCDMA wideband code division multiple access
- the invention is further closely related to an enhanced uplink dedicated transport channel (EUDCH).
- EUDCH includes new base station functions such as high-speed retransmission and scheduling of uplink data packet data. Background art
- a radio network controller controls the data rate of uplink packet data transmission for a plurality of mobile stations (MSs).
- Uplink data rate scheduling by the radio network controller can be combined with scheduling by the base station (BTS) to achieve better radio link efficiency, thereby increasing system capacity. be able to.
- BTS base station
- One example of this combination of RNC and BTS packet scheduling is a so-called enhanced dedicated channel (EUDCH).
- EUDCH enhanced dedicated channel
- EUDCH In addition to the packet scheduling capability of the base station, EUDCH provides the base station with an automatic retransmission (ARQ) function to move retransmission of erroneous data packets without involvement of a radio network controller.
- ARQ automatic retransmission
- BTS ARQ is progressively faster than RNC ARQ, and therefore the former outperforms the latter in terms of the delay required for retransmission.
- a mobile station When a mobile station has multiple uplink data flows, different scheduling methods can be used for different data flows, depending on the requirements of this flow. For example, optimizing BTS scheduling mainly for Best F On the other hand, if RNC scheduling can better control the voice call service, the mobile station may use multiple scheduling data modes, using the appropriate scheduling mode to meet the needs of each data flow. Can be transmitted.
- FIG. 1 is a diagram showing a system including BTSZRNC scheduling and ARQ.
- MS1-MS3 101-103 in the cell Three types of mobile stations (MS1-MS3) 101-103 in the cell are connected to a base station (BTS) 104 controlled by a radio network controller (RNC) 105.
- the two mobile stations (MS2, MS3) 102, 103 marked “BtsSch” are the mobile stations scheduled by the BTS, and the two mobile stations (MS1, MS1, MS3) marked “RncSch”.
- MS3) 101, 103 are scheduled by the radio network controller 105.
- the MS3 103 has two data flows, and each flow has a different scheduling mode, namely BtsSch and RncSch. In other words, MS3 103 has two uplink data flows, while MS1 101 and MS2 102 have one uplink data flow.
- the data rate of the MS2 102 and the data rate of the first flow of the MS3 103 are controlled by the base station 104, and the radio network controller 105 controls the data rate of the MS1 101 and the data rate of the second flow of the MS3 103. Control the speed.
- the retransmission of MS2 102 and the retransmission of the first flow of MS3 103 are requested by the base station, while the radio network controller retransmits the MSI 101 and the second of MS3 103. Controls retransmission of flows. It is important to note that MS1 101 is connected to both base stations 104, 104A at the same time and radio network controller 105 combines the data packets received from the two base stations 104, 104A.

- the radio network controller should set an appropriate power offset for the BTS scheduling data packet (EUDCH data flow). If the power offset is set too high, the probability of error is very low, and as a result, there is no advantage to performing base station level ARQ processing. Become. If the power offset is set too low, the large error probability will increase the total latency of uplink data packet transmission. To make this problem more difficult, if the data packet frame lengths of DCH and EUDCH are different, the radio network controller should also consider the difference in the interleave gain of DCH and EUDCH. For example, when the moving speed of the mobile station changes randomly with time, the interleave gain of DCH and EUDCH also changes randomly.
- Transmission power control for DCH and EUDCH data flows should allow for high! Link efficiency, even when there is a difference in DCH and EUDCH soft handover gains. For example, when two base stations receive one DCH data flow, only one base station receives power.3 ⁇ 4 When receiving a UDCH data flow, this transmission power control uses the transmission power of both DCH and EUDCH as “simultaneously and efficiently. (simultaneously efficient)] If only one of the DCH and EUDCH is optimized, the line quality on the other channel will be degraded.

- the present invention solves a problem associated with fast changes in the interleaving gain difference between two data flows due to different frame lengths of the two flows.

This recommendation from the base station allows the radio network controller to determine the new V, power offset of the EUDCH data flow. The detailed process of assigning this new power offset by the radio network controller will be described below! /
- FIG. 5 shows a flowchart of the processing of the wireless network control device.
- the radio network controller receives the required power offset of the base station power of the group that receives the EUDCH data flow. Calculate the difference between the required power offset and the currently assigned power offset.
- the radio network controller determines whether this required power offset is being transmitted by the serving base station that receives the EUDCH data packet most frequently compared to other base stations. Inspect If not, in step 508, the radio network controller rejects this reported required power offset. If this power offset has been transmitted by the serving base station, in step 504 the radio network controller checks whether the required power offset is smaller than the currently assigned power offset.
- the radio network controller accepts this recommendation and sends the newly allocated power offset to these base stations. If not, the radio network controller accepts this recommendation in steps 506, 507 if the data flow is a high priority flow or is sensitive to delay. Otherwise, in step 508, the radio network controller rejects this required power offset.
- the radio network controller utilizes the priority and delay sensitivity of the data flow when deciding to increase the required power offset.
- the advantage associated with this process is that prioritization is done to accommodate high-priority or delay-sensitive flows rather than the limited overall radio resource power of low-priority best-effort flows. To be done.
- the radio network controller accepts only the required base station power and the required power offset.
- the advantage of this process is to minimize the required power offset by selecting the best quality base station and thus increasing the uplink packet transmission capacity.
- FIG. 6 shows another possible implementation of the system according to the invention.
- This example system is an extension of the implementation of the above-described system shown in FIG. The differences between the two systems are explained below.
- FIG. 6 There are two EUDCH data flows in addition to one DCH data flow.
- Figure 2 The system described above had only one EUDCH data flow. Therefore, the system in Fig. 6 is an extended system for the case where there are multiple EUDCH data flows transmitted on the uplink.
- Each EUDCH data flow may have different requirements for the target error rate due to different Quality of Service (QoS) requirements.
- QoS Quality of Service
- transmitted data packets are separately encoded for each data flow in order to support different QoS for each data flow.
- the mobile station 10 shown in FIG. 6 is provided with two EUDCH data transmission units (EDCH1 Tx, EDCH2 Tx) 601 and 602 for two data flows, a time multiplexer (SW) 604, and a power S. I have.
- the base station is provided with two power offset estimators (# 1, # 2) 607, 608.
- Switching in the timer multiplexer 604 is to implement a choice for transmission from the two data flows. For example, when both flows have enough data to wait for transmission, switching can implement a round-robin selection between the two data flows. This is to control the target error rate of each data flow separately.
- base station 20 Based on the reception of the transmitted EUDCH data flow, base station 20 performs decoding of the EUDCH data flow in EUDCH decoder 606.
- the normally decoded data is transferred to the RNC 30, and the reception status of the data flow is reported to the power offset estimators 607 and 608.
- the base station has two separate EUDCH data flows. There are power offset estimators 607 and 608. Therefore, the reception status of the EUDCH data flow is updated only for the corresponding power offset estimator. For example, when the base station receives the first EUDCH data flow, the power offset estimator that updates the power offset of the first EUDCH data flow uses this reception status to determine the new level of the required power offset. Will be calculated. This calculation is performed by the same processing as shown in FIG.
- Both the base station 20 and the mobile station 10 control the retransmission of the data flow by the master control unit, that is, the ARQ transmitting unit 605, and the slave control unit, that is, the ARQ receiving unit 609.
- ARQ transmitting section 605 serves as a retransmission master control section in a mobile station handling both EUDCH data flows
- ARQ receiving section 609 serves as a retransmission slave control section in a base station handling both EUDCH data flows. Plays a role.
- the retransmission information consists of the reception status and the corresponding data flow identifier. The identifier can be transmitted explicitly or can be implicitly reduced from the fixed timing between the uplink and downlink control data transmissions.
- RNC radio resource control section 610 Separate power offsets for the two EUDCH data flows calculated by the base station are reported to RNC radio resource control section 610. Based on the reported power offset, RNC 30 makes a decision on the power offset for each EUDCH data flow in the same manner as described in FIG. For example, if two EUDCH data flows have different priorities and base station 20 reports a larger power offset for both data flows, the RNC will only determine the power offset of the higher priority data flow. It cannot be increased and will reject lower priority power offsets. The RNC then communicates the newly assigned power offset to the mobile station and the base station.
- a key aspect of the proposed implementation in Figure 6 is to use two separate closed control loops for each EUDCH data flow.
- the base station calculates the required power offset separately for each data flow, reports the power offset separately to the radio network controller, and then the radio network controller again decides separately on the new power offset I do.
- This separate closed-loop power offset control allows each data flow One QoS can be controlled separately, so that, for example, higher priority data flows can be guaranteed more uplink power than lower priority data flows. Note that this proposed system can be extended even if there is more than two! EUDCH data flows!
