Embodiment 1

[0040] Method Embodiment 1, this embodiment proposes: on the terminal side, as long as the terminal is monitoring the control channel, it will respond to the scheduling information no matter whether it is monitoring new data scheduling information or retransmission data scheduling information.

[0041] In a mobile communication system based on a shared channel and using a multi-process parallel stop-and-wait HARQ protocol to realize discontinuous data scheduling, assuming that the terminal side maintains three processes, the first process, the second process, and the third process, the three Each process shares one DRX on duration Timer and one DRX inactivity Timer, and for each process, the terminal is set with a HARQ RTT Timer and a HARQRetransmission Timer.

[0042] Example 1, after the DRX on duration Timer and DRX inactivity Timer of the terminal both time out, if the HARQ Retransmission Timer set by the terminal has not timed out, then during the operation of the HARQ Ret...

Embodiment 2

[0072] Method embodiment 2, this embodiment further proposes on the basis of method embodiment 1: after the network side learns that the terminal is monitoring the control channel, regardless of whether the terminal is running the method specified in the prior art for monitoring the new Either the timer for timing the data scheduling information or the timer for monitoring the timing of the retransmission data scheduling information can schedule new data and retransmission data for the terminal.

[0073] Figure 4 is a flow chart of the second embodiment of the method of the present invention, and provides a specific method for scheduling a terminal when the base station needs to schedule the terminal, as shown in Figure 4 As shown, the method includes:

[0074] Step 401 , the base station judges whether the terminal is still monitoring the control channel in the current DRX cycle, if yes, execute step 402 , otherwise execute step 403 .

[0075] Step 402, the base station s...

Abstract

The embodiment of the invention discloses a method for discontinuously receiving data, which is applied to a mobile communication system based on a shared channel. The method includes the steps that a terminal monitors and responds the data dispatching information except for the special data dispatching information when a timer for timing for receiving the special data dispatching information runs. The embodiment of the invention also discloses equipment for discontinuously receiving data, a system and equipment for discontinuously dispatching data. Due to the adoption of the technical scheme provided by the embodiment of the invention, the possibly emerged abnormal situation that the mobile communication system based on the shared channel and adopting an HARQ protocol such as multi-process parallel working and stopping is used for discontinuously receiving data can be solved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a discontinuously receiving data method and equipment, and a discontinuously dispatching data system and equipment. Background technique [0002] In a mobile communication system based on a shared channel, such as a Long Term Evolution (Long Term Evolution, LTE) system, a base station scheduler generally controls the transmission of uplink and downlink data. When the base station scheduler determines to schedule a certain terminal, it will send scheduling information to the terminal through the control channel. The scheduling information carries resource parameters for the terminal to send or receive data. The terminal monitors the control channel. When scheduling information, the sending of uplink data or the receiving of downlink data is completed according to the indication of the scheduling information. [0003] The terminal can monitor the control channel only when it is...
