The MAC-hs entity configured in the Node B of HSDPA is mainly responsible for performing functions such as flow control, fast packet scheduling, performing HARQ protocol, and TFRC selection. The fast packet scheduling is used to determine which user service is selected for a given TTI, and may be based on a radio channel quality indicator (CQI), the amount of data waiting to be transmitted, the priority of the service, and the user equipment (User Equipment). Factors such as the capability class of the UE and the resources that can be allocated quickly realize the allocation of shared resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention are described with reference to the accompanying drawings. The basic idea of the present invention is to pre-configure CQI tables under different initial BLERs, and when performing a packet scheduling algorithm scheduling to a certain UE, determine a service class of data to be sent to select a CQI table corresponding to the corresponding initial BLER, and then combine the allocated powers. And the code resource and the amount of data to be transmitted complete the TFRC selection for the first transmission or retransmission. 1 shows a flow chart of a TFRC selection method in an HSDPA system in accordance with the present invention. As shown in FIG. 1, the TFRC selection method in the HSDPA system of the present invention includes a configuration step 102, a determination step 104, and a selection step 106. In configuration step 102, CQI tables under various initial BLER conditions for different UE categories are configured. The CQI table of 10% initial BLER as specified in the agreement and the CQI form of 20% or 15% or 5% initial BLER obtained by link simulation. In the determining step 104, the service category of the data to be transmitted is determined to select a corresponding CQI table corresponding to the initial BLER. Determining whether the data to be transmitted of the UE is a real-time stream class or a non-real-time interaction class/background class by detecting whether the radio link establishment or the radio link reconfiguration message cell contains a cell parameter related to the guaranteed bit rate, and then according to the configuration parameter Select the CQI table corresponding to the initial BLER. A higher initial BLER can be used for non-real-time interaction/background traffic data that requires less delay, and a lower initial BLER can be used for real-time streaming traffic data with strict delay and guaranteed bit rate requirements. In step 106, the TFRC selection is performed according to the service category of the data to be sent, and the allocated power resource, code resource, and amount of data to be sent. The HS that the packet scheduler actually allocates to the UE according to the previous scheduling period. - Correction of the CQI reported by the UE by the difference between the total power of the PDSCH and the measured power deviation (Measured Power Offset, hereinafter referred to as MPO) and the estimated total power of the HS-PDSCH transmitted according to the protocol-defined method. The CQI is:

Where CQ ¹ ' is the corrected CQI reported value, ^CQI is the CQI value reported by the UE, ΔΡ is the power difference expressed in dB as described above, and L" is the rounding down operator. FIG. 2 shows a block diagram of the structure of the network side MAC-hs. The MAC-hs entity first performs MAC-Hs and MAC-c/sh or HS-DSCH data frame transmission between MAC-hs and MAC-d through the flow control module (step 201). The scheduling/priority processing module then manages the HS-DSCH resources between the HARQ entity and the data stream according to the priority to complete the allocation of the shared resources (step 202), and the HARQ entity is responsible for processing the HARQ function of one user (step 203), TFRC selection The module is then responsible for selecting a suitable TFRC for the data transmitted on the HS-DSCH to accommodate the radio link channel conditions (step 204). The packet scheduler and the TFRC selection module are independent of each other, but work in coordination. Figure 3 shows a flow chart of the initial BLER configuration in the Node. First, CQI table data of 10% initial BLER of different UE classes specified by the protocol needs to be configured in the Node B (step 301), as shown in Table 1 (UE class 10;). Table 1 CQI mapping table of UE category 10

The reference power adjustment Δ in Table 1 is a transmission power correction term for a UE class that does not support all CQIs specified by the protocol. Since the UE class 10 supports all CQIs, this is 0. The NIR is the soft buffer size of each HARQ process on the UE side, and the XRV is the RV parameter recommended by the UE. The initial BLER of Table 1 is 10%, and CQI tables of other initial BLERs (such as 20%, 15%, or 5%, etc.) of different UE categories can be obtained through link simulation, and saved in Node B (step 302). ). For the QoS characteristics of the real-time flow class and the non-real-time interaction class/background service, the CQI table index parameters corresponding to the initial BLER are respectively configured for the next TFRC selection, and the cable 1 parameter is used to match the service QoS feature. The CQI table corresponding to the initial BLER (step 303). The real-time streaming service has guaranteed bit rate requirements and is sensitive to delay. The lower initial BLER can be configured, such as 5%, to reduce the number of HARQ retransmissions and ensure its QoS. For non-real-time interactive/background services, a relatively high initial BLER such as 10%, 15%, or 20% can be configured to fully utilize the HARQ retransmission gain. The initial BLER selection of 1" for service categories" allows for flexible configuration. Figure 4 shows the overall flow of TFRC selection in HSDPA. First, it is judged whether there is a "MAC-hs Guaranteed Bit Rate" parameter in the "HS-DSCH MAC-d Flows Information" cell (step 401). If the parameter exists, the data transmitted through the HS-DSCH is a real-time streaming service with a guaranteed bit rate requirement, and a CQI table corresponding to the initial BLER that satisfies the QoS requirement may be selected for the flow type service (step 402); For the parameter, the data transmitted through the HS-DSCH is a non-real-time interaction class/background service without a guaranteed bit rate requirement, and a CQI table corresponding to the loose initial BLER may be selected for the interaction class/background service (step 403). There may be a deviation between the total power of the HS-PDSCH actually allocated to the UE by the packet scheduling schedule in the previous scheduling period and the total power of the HS-PDSCH estimated by the MPO configured by the upper layer and according to the protocol-defined method, according to the formula (1.1). Correcting the CQI reported by the UE (step 404), and then confirming whether the transmission is the first transmission (step 405). If it is the first transmission, performing TFRC selection according to the first transmission mode (step 406), if it is retransmission, The TFRC selection is performed according to the retransmission mode (step 407). Figure 5 shows the TFRC selection procedure during retransmission. First, the appropriate RV parameters are configured for the retransmission according to the HARQ policy (step 501), and then the first transmission is used. The transport block size, the modulation strategy, and the number of code channels in the TFRC (step 502), and then select the above transport block size, modulation strategy, number of code channels, and RV parameters to form the TFRC of the retransmission (step 503) „ due to There may be a difference between the CQI used in the first transmission and the CQI reported in step 304. The power resources and code resources actually needed for this retransmission need to be re-calculated. :

P _pml = P _pye +ACQn (in dB) , After the power (step 504) is calculated according to actual needs of retransmission, which is actually required power resource, Ρ ^'¾ power of the UE is allocated to the packet scheduler, AC ⁷¹ subtracts corrected to a CQI corresponding to the first TFRC transmission The difference between the CQI and the reported value. And applying the actual required power resources and code resources to the packet scheduler (step 505). Figure 6 shows the TFRC selection procedure for the first transmission. First, the appropriate RV parameter is configured for the first transmission according to the HARQ policy (step 601), and then the corrected CQI report value obtained in step 304 is used to query the CQI table (step 602), and then it is determined whether the number of allocated code channels is smaller than CQI. The number of corresponding code channels (step 603). If the number of code channels allocated is less than the number of code channels corresponding to the CQI, the CQI set whose number of code channels is not greater than the number of allocated code channels needs to be selected from the CQI table (step 604); if the number of code channels allocated Not less than the number of code channels corresponding to the CQI, it is necessary to select a CQI set that is not larger than the corrected CQI report value from the CQI table (step 605). Since the amount of data to be transmitted by the UE may be smaller than the transport block size corresponding to the CQI, it is necessary to search for the CQI corresponding to the maximum transport block size that is not larger than the data volume to be transmitted from the CQI set (step 606), and use the CQI as this time. The CQI value actually used in the CQI mapping is used to form the TFRC by using the CQI corresponding transport block size, modulation strategy, number of code channels, and configured RV parameters (step 607). ₀ Corrected by the CQI and step 404. There may be a difference between the reported values of the CQI, and the actual power resources and code resources of the first pass need to be re-calculated, according to the following formula.

Ρ _{ρ υ} , = Ρ _ρι , _CQI2 (in dB) _{( 1 3 ) to} calculate the actual required power (step 608 ), where, for the actual required power resource, ^P p '. ^e is the power allocated to the UE by the packet scheduler, ^C Q ⁿ is the difference between the selected CQI value and the corrected CQI reported value. And apply to the packet scheduler for the actual required power resources and code resources (step ^ ^ 609 ). FIG. 7 is a schematic diagram 1 of a TFRC selection device 700 in HSDPA, in accordance with one embodiment of the present invention. As shown in FIG. 7, the apparatus 700 includes a configuration module 702, a determination module 704, and a selection module 706. The configuration module 702 is configured to configure CQI tables under various initial BLER conditions of different user terminal equipment categories. The CQI table of 10% initial BLER as specified in the protocol and the CQI table of 20% or 15% initial BLER and 5% initial BLER obtained by link simulation. The determining module 704 is configured to determine a service category of the data to be sent, to select a corresponding initial BLER corresponding CQI table, and determine a transmission mode of the data to be transmitted. By detecting whether there is a "MAC-hs Guaranteed Bit Rate" parameter in the "HS-DSCH MAC-d Flows Information" cell of the Iub interface, it is determined whether the data to be sent by the UE is a real-time stream class or a non-real-time interaction class/background class, and then according to The configuration parameters select the CQI table corresponding to the initial BLER. The higher initial BLER can be used for non-real time interaction class/background type service data that is not sensitive to delay requirements, and the lower initial BLER can be used for real time stream class service data with strict delay and guaranteed bit rate requirements. In addition, the determining module 704 also determines the transmission mode of the data to be sent. If the data transmission is the first transmission, the selection module 706 performs TFRC selection in the first transmission mode. If it is retransmission, the selection module 706 presses the following. Retransmission mode for TFRC selection. The selection module 706 is configured to perform TFRC selection according to the service category of the data to be transmitted and the above transmission mode. The TFRC selection is performed in combination with the allocated power resources, code resources, and the amount of data to be transmitted. In the process of TFRC selection, the selection module 706 may further allocate, according to the last scheduling period, the total power of the HS-PDSCH actually allocated to the UE by the scheduler and the measurement power offset (Measured Power Offset, MPO) of the upper layer configuration. The difference ΔΡ between the total power of the HS-PDSCH transmission estimated according to the method specified by the protocol is corrected for the CQI of 4艮 on the UE according to the formula (1.1). The HSDPA TFRC selection method according to the present invention can fully consider the flow class. The QoS difference between the service and the interaction type and the background type service may be corrected according to the total power of the HS-PDSCH actually allocated to the UE in the previous scheduling period, and the first time transmission and retransmission are performed in the TFRC selection. The TFRC selects, and considers that the number of code channels allocated to the UE may be smaller than the number of code channels corresponding to the CQI, and the amount of data to be transmitted by the UE may also be smaller than the transmission block size corresponding to the CQI, according to actual required power resources and codes. The resource re-applies to the packet scheduler to improve the utilization of power resources and code resources, so that the link between the AMC and the HARQ can be completed together with the packet scheduling algorithm. The HSDPA TFRC selection method according to the present invention can ensure that the scheduled user's throughput is the largest and the service QoS is satisfied. The above description is only a preferred embodiment of the present invention, and is not used for limitation. The invention may be variously modified and changed by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles are intended to be included within the scope of the present invention.
