Embodiment 1

[0065] Step 1, introduce the SG determination method of the present invention in 3GPP Rel 10, that is, when the version of the UE is Rel 10, it means that the UE supports the new Δ E-DPDCH Quantization table; of course, the SG determination method of the present invention may also be introduced in other versions as required, and is not limited to 3GPP Rel 10.

[0066] The UE reports its own version information to the RNC, and the RNC can know that the UE supports the new Δ E-DPDCH Ability to quantize tables.

[0067] Step 2, RNC decides UE to use new Δ E-DPDCH Quantization table, decision UE uses 16QAM and does not use E-TFCI boost, and notifies Node B of these configuration information; preferably, RNC informs UE to use new Δ E-DPDCH The decision result of the quantization table is notified to Node B; the UE uses the new Δ E-DPDCH The decision result of the quantization table is notified to the UE. The above-mentioned newly added information elements are all optional info...

Embodiment 2

[0091] This embodiment is basically the same as Embodiment 1, the difference is that in step 2, the RNC decides that the UE uses the new Δ E-DPDCH Quantization tables and decisions do not use 16QAM and do not use E-TFCI boost.

[0092] In this embodiment, since the UE configuration does not use 16QAM and does not use E-TFCI boost, it can be seen from Table 4 that Δ E-DPDCH The maximum quantization value of the HSUPA can reach 267 / 15, while the existing technology can only reach 168 / 15, so that the maximum rate that can be achieved is improved, so that the high-speed characteristics of HSUPA can be fully utilized.

Embodiment 3

[0094] This embodiment is basically the same as Embodiment 1, except that in step 2, the RNC decides that the UE does not use the new Δ E-DPDCH Quantization table, decision to use 16QAM and not use E-TFCI boost, and notify the node B of these configuration information.

[0095] In this embodiment, since the RNC decides that the UE does not use the new Δ E-DPDCH The quantization table (namely Table 4), the decision to use 16QAM and not use the E-TFCI boost, then it can be known from Table 3 that the UE uses Table 1.

[0096] Then, the determination process of SG is the same as step 7 of the first embodiment, the difference is that Table 1 should be referred to instead of Table 4.

Abstract

The invention discloses a confirmation method for schedule granting and user equipment thereof. The method is as following: when the ratio of the non-quantitative power gain factor of a dedicated physical data information channel (E-DPDCH) of a enhanced dedicated transmission information channel to the power gain factor of DPCCH is smaller than the minimum delta E-DPDCH quantitative value in a delta E-DPDCH quantitative table, the E-DPDCH power gain factor required by the combined indication (E-TFCI) of the transmission format of the enhanced dedicated transmission channel is set to the E-DPDCH power gain factor corresponding to the minimum delta E-DPDCH quantitative value; otherwise, confirming E-DPDCH power gain factors which are less than or equal to the E-DPDCH non-quantitative power gain factors corresponding to each delta E-DPDCH quantitative value in the delta E-DPDCH quantitative table, and the maximum value is chosen and set to the E-DPDCH power gain factor required by E-TFCI; and summing the square of each E-DPDCH power gain factor required by E-TFCI to obtain the schedule (SG) required by E-TFCI. The confirmation method for schedule granting and user equipment thereof solves the defect in the prior art that UE cannot achieve the maximum rate under the confirming method for schedule granting.

Description

technical field [0001] The present invention relates to a High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) system, in particular to a method for determining scheduling authorization and user equipment. Background technique [0002] In order to improve the uplink capacity and coverage of the system and meet the user's uplink high-speed service requirements, 3GPP introduced an enhanced dedicated channel (E-DCH, Enhanced Dedicated Channel) in the uplink direction in R6, which is similar to the uplink dedicated channel of R99 / 4 / 5 ( Compared with DCH, Dedicated Channel), E-DCH moves the scheduling function from the radio network controller (RNC, Radio Network Controller) to the node B (NodeB) to achieve fast packet scheduling, and uses fast hybrid automatic repeat request (HARQ , HybridAutomatic Repeat Request) technology to achieve fast retransmission at the physical layer. During scheduling, the NodeB adopts a certain scheduling algorithm based on f...
