Problems solved by technology

[0009] Different from the physical layer signaling related to HS-PDSCH reception carried by HS-SCCH, after the entry / exit DRX command is sent, there is no subsequent HS-PDSCH sending and receiving process, and there is no explicit HS-SICH sending and receiving process, so that there is no further interaction process between Node B and UE, and the entry / exit DRX command itself changes the sending and receiving mode of the HS-SCCH channel, so it may cause when sending the entry / exit DRX command, Effective acknowledgment is not possible, that is, the sending side does not know whether the receiving side correctly received the command it sent
If the configuration of the sending side and the receiving side are inconsistent due to the failure to receive the entry / exit DRX command, it will seriously affect the normal data transmission process and the UE's power saving function

Embodiment 1

[0045] Embodiment 1: The feedback information control channel is H-SICH

[0046] In the HSDPA technology of the TD-SCDMA system, the Node B on the network side uses a dynamic scheduling method to allocate the HS-PDSCH radio channel and other related resources to the UE. Among them, the Node B sends related control information through the resource allocation control channel (HS-SCCH). The information is sent to the UE, and the UE feeds back the HS-PDSCH channel reception information to the Node B through the information feedback control channel (HS-SICH).

[0047] In related technologies, in order for the Node B to initiate HSDPA transmission at any time, the UE needs to continuously monitor the HS-SCCH channel. In order to reduce UE power consumption when there is no HSDPA transmission for a long time, the Node B can order the UE to enter the HS-SCCH DRX state, and at the same time, the Node B enters the HS-SCCH DTX state for the UE. After the Node B and the UE enter the HS-S...

Embodiment 2

[0063] Embodiment 2: The feedback information control channel is a non-scheduled E-PUCH

[0064] Compared with Embodiment 1, in this embodiment, the information feedback control channel is a non-scheduled E-PUCH channel in the HSUPA (that is, E-DCH) technology. In this application scenario, according to the embodiment of the present invention, the control method for the user equipment to enter / exit the DRX state specifically includes the following processing:

[0065] 1. The network side initially allocates HS-SCCH channel and non-scheduled E-PUCH channel resources for UE as resource allocation control channel and information feedback control channel, configures the cycle of DTX and DRX of HS-SCCH channel, and sends them through high-layer signaling to UE (801). The resource allocation process is similar to Embodiment 1, and is the same as the current HSDPA and HSUPA technologies, so no detailed description is given here.

[0066] 2. When performing HSDPA transmission contro...

Abstract

The invention discloses a control method of user equipment enter / exit discontinuous receiving state, wherein, the Node B transmits control commands in a user equipment for commanding the user equipment enter or exit the discontinuous receiving state of resource allocation control channel; the user equipment receives the resource allocation control channel and perform the corresponding feedback operations according to whether the control commands are received rightly; the Node B can perform the subsequent processing according to the feedback case of the user equipment. According to the invention, the reliability for transmitting commands can be improved, meanwhile, the transmitting and the receiving states of the resource allocation control channels on the transmitting side and the receiving side can be kept in consistence, thereby ensuring the normal data transmitting process and implementing the consumption-saving function of the terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a control method for user equipment to enter / exit the discontinuous reception state in a wireless communication system that uses a dynamic scheduling method to allocate wireless channel resources. Background technique [0002] In the High Speed ​​Downlink Package Access (HSDPA) technology of the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, the wireless physical channel resources include : High Speed ​​Physical Downlink Shared Channel (HS-PDSCH for short), Shared Control Channel for HS-DSCH (HS-SCCH for short) and Shared Information Channel for HS -DSCH, abbreviated as HS-SICH). [0003] Such as figure 1 As shown, between the Node B on the wireless network side and the user equipment (User Equipment, UE for short), the HS-PDSCH carries user data information from the Node B to the UE, and the resource allocation control information used ...
