Problems solved by technology

[0009] for figure 1 and figure 2 In the two cases shown, if HS-SICH1 and HS-SICH2 are two different HS-SICHs, there is usually no problem; however, if HS-SICH1 and HS-SICH2 are the same HS-SICH, then at this time, in TTI=N+3, UE needs to perform two feedbacks at the same time through HS-SICH1 / HS-SICH2, and how to use one HS-SICH to carry two feedbacks is not stipulated in the current agreement, and the agreement also does not stipulate the base station How to proceed to the next step after receiving the feedback information
[0010] In addition, the current agreement stipulates that the UE is only allowed to send two uplink physical channels in one time slot. If HS-SICH1 and HS-SICH2 are two different HS-SICHs, but they are located in the same time slot, then If the UE needs to send other uplink physical channels, such as the uplink enhanced random access channel (E-RUCCH, E-DCH Random Access Uplink Control Channel), then the UE must discard one of the uplink physical channels, but no matter which one is discarded A physical channel will cause a certain performance loss, so it is hoped that two feedbacks can be carried on one HS-SICH to save code channel resources

Embodiment 1

[0036] image 3 It is a flow chart of the first embodiment of the method of the present invention. Assume that in this embodiment, the two feedbacks are the feedback for semi-persistent resource configuration or reconfiguration command and the feedback for downlink data reception, and the corresponding HS-SICHs are as follows: figure 1 As shown, then as image 3 As shown, this embodiment includes the following steps:

[0037] Step 301: The UE determines whether it has received a semi-persistent resource configuration or reconfiguration command and downlink data from the base station, and if so, executes step 302; otherwise, no feedback is given, and the process ends.

[0038] Such as figure 1 As shown, at TTI=N, the base station sends a semi-persistent resource configuration or reconfiguration command to the UE, indicating that the semi-persistent HS-PDSCH resource takes effect from TTI=N+1, with a period of 4 TTIs, and at the indicated The downlink data is sent on the HS-...

Embodiment 2

[0048] Figure 4 It is a flow chart of the second embodiment of the method of the present invention. Assume that in this embodiment, the two feedbacks are the feedback for HS-SCCH order and the feedback for downlink data reception, and the corresponding HS-SICHs are as follows: figure 2 As shown, then as Figure 4 As shown, this embodiment includes the following steps:

[0049] Step 401: The UE determines whether the HS-SCCH order from the base station and the traditionally scheduled HS-SCCH are received at the same time, if yes, execute step 402; otherwise, execute step 405.

[0050] Such as figure 2 As shown, when TTI=N, the base station sends the HS-SCCH order to the UE to deactivate the DRX, and at the same time, sends the traditionally scheduled HS-SCCH.

[0051] Step 402: The UE further determines whether the HS-SICHs corresponding to the two feedbacks that need to be sent to the base station are the same HS-SICH, if yes, execute step 403, otherwise, execute step 4...

Abstract

The invention discloses a method for feeding back information, which comprises the following steps of: A, determining whether to need to simultaneously carry out two feedbacks or not by a user terminal (UE) and executing the step B if so; B, determining whether high-speed shared control channels (HS-SICH) corresponding to the two feedbacks are the same HS-SICH or not and executing the step C if so, and otherwise executing the step D; C, carrying out feedback by utilizing the same HS-SICH; and D, carrying out feedback by utilizing a preset designated HS-SICH in the two HS-SICHs. Meanwhile, the invention discloses a system for feeding back the information and the user terminal. Through the method, the system and a device of the invention, two feedbacks can be borne by utilizing one HS-SICH so as to save code channel resources.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an information feedback method, system and device in a mobile communication system. Background technique [0002] In the traditional high-speed downlink packet access (HSDPA, High Speed ​​Downlink PacketAccess) technology, the high-speed shared control channel (HS-SCCH, High Speed ​​Shared Control Channel) is used to carry the high-speed physical downlink shared channel (HS-PDSCH, High SpeedPhysical Downlink Shared Channel) scheduling and control information. The base station (NodeB) sends downlink control information on the HS-SCCH, indicating that the subsequent HS-PDSCH of the user terminal (UE, User Equipment) carries downlink data; after the UE correctly interprets the HS-SCCH, it receives the indicated HS-PDSCH ACK / NACK information and Channel Quality Indicator (CQI, Channel Quality Indicator) information ( The base station will pre-configure a set of monitored H...
