Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a discontinuous reception processing method, a user terminal, and a network device.
Background
In a DRX (Discontinuous Reception) mechanism, a UE (User Equipment) periodically enters a sleep state, does not monitor a PDCCH (Physical Downlink Control Channel) subframe, and wakes up from sleep only when monitoring is needed, thereby achieving a power saving purpose.
However, the prior art has the following problems: as shown in fig. 1, the UE is likely to enter the sleep period soon after reporting the BSR (Buffer Status Report), and therefore the base station cannot schedule the UE in time, and can only wait until the UE enters the active period again. Therefore, some services sensitive to delay, such as Voice over LTE (Voice over LTE) Voice services, cannot be sent in time, which may cause a delay jitter problem and reduce user experience.
One possible solution is to set a longer DRX inactivity timer as shown in fig. 2, but the resulting problem is that the UE is awake most of the time, which is not good for UE power saving.

The discontinuous reception processing method of the present invention is further described with reference to the following specific embodiments:
the first embodiment is as follows: the network side equipment indicates the uplink new transmission-a plurality of active period extension timers with different lengths are issued in the DRX configuration information
In this embodiment, the network side device sends 3 DRX-inactivytytimers with different lengths to the UE through DRX configuration information, where the lengths are 2 PDCCH subframes, 4 PDCCH subframes, and 8 PDCCH subframes, respectively; these 3 lengths correspond to 3 LCGs (logical channel groups) of the UE, respectively.
And the network side equipment instructs the UE to perform uplink new transmission. As shown in fig. 6, the UE combines the current buffering situation: data without LCG1 is to be transmitted, and data buffering of LCG2 and LCG3 is provided, so the UE selects the maximum value of 4 PDCCH subframes and 8 PDCCH subframes, namely, the drx-InactivetyTimer with the length of 8 PDCCH subframes is started.
After the uplink data is sent, the UE buffer only has the buffer of LCG1, so the UE starts the drx-inactivytytimer with the length of 2 PDCCH subframes. And after the drx-InactivityTimer is timed out, the UE enters a sleep period.
Example two: network side equipment indicates uplink new transmission-a plurality of active period extension timers with different lengths are issued in logical channel LCH configuration information
In this embodiment, the network side device sends 3 drx-inactivytytytimers with different lengths to the UE through the LCH configuration information. In the configuration information of the first LCH, the length of the drx-InactivetyTimer is 8 PDCCH subframes; in the configuration information of the second LCH, the length of drx-InactivetyTimer is 2 PDCCH subframes; in the configuration information of the third LCH, the drx-inactivity timer length is 4 PDCCH subframes.
And the network side equipment instructs the UE to perform uplink new transmission. The UE combines the current caching situation: only the data of LCH2 and LCH3 are buffered, so the UE selects the maximum of 2 PDCCH subframes and 4 PDCCH subframes, i.e. starts drx-inactivytimer with a length of 4 PDCCH subframes.
Example three: the network side equipment indicates the uplink new transmission-a plurality of active period extension timers with different lengths to issue in the DRX configuration information and the LCH configuration information
The network side equipment sends 3 DRX-InactivetyTimers with different lengths to the UE through DRX configuration information, wherein the lengths of the DRX-InactivetyTimers are respectively 2 PDCCH subframes, 4 PDCCH subframes and 8 PDCCH subframes; correspondingly, the network side equipment indicates that the drx-inactivytytimer length with the sequence number of 2, namely 8 PDCCH subframes, is adopted in the configuration information of the first LCH; indicating that 2 PDCCH subframes are adopted in the configuration information of the second LCH, wherein the drx-InactivetyTimer length with the serial number of 0 is adopted; in the configuration information of the third LCH, a drx-inactivity timer length with a sequence number of 2, that is, 4 PDCCH subframes, is indicated.
Example four: network side equipment indicating downlink new transmission
The network side equipment sends 3 DRX-inactivity timers with different lengths to the UE through the DRX configuration information, wherein the lengths of the DRX-inactivity timers are respectively 0 PDCCH subframe, 2 PDCCH subframes and 8 PDCCH subframes; these 3 lengths correspond to 3 logical channel groups of the UE, respectively.
As shown in fig. 7, the network side device instructs the UE to perform downlink retransmission, and simultaneously instructs the UE network side to send the LCG2 and LCG3 through the downlink MAC CE. Therefore, after receiving the PDCCH indication, the UE selects the maximum value of 2 PDCCH subframes and 8 PDCCH subframes, i.e., starts the drx-inactivity timer with a length of 8 PDCCH subframes.
during the operation of the drx-inactivity timer, the UE receives a new MAC CE indication from the network side device, and indicates that the network side has data of the LCG2 to be sent, so the UE starts the drx-inactivity timer with a length of 2 PDCCH subframes.
during the operation of the drx-inactivity timer, the UE receives a new MAC CE indication from the network side device to indicate that the network side still has LCG1 data to send, so the UE starts the drx-inactivity timer with a length of 0 PDCCH subframe.
Example five: network side equipment indicating downlink new transmission
The network side equipment sends 3 DRX-InactivetyTimers with different lengths to the UE through DRX configuration information, wherein the lengths of the DRX-InactivetyTimers are respectively 4 PDCCH subframes, 2 PDCCH subframes and 8 PDCCH subframes; these 3 lengths correspond to 3 logical channel groups of the UE, respectively.
As shown in fig. 8, the network side device instructs the UE to perform downlink retransmission, and simultaneously instructs the UE network side to send the LCG2 and LCG3 through the downlink MAC CE. Therefore, after receiving the PDCCH indication, the UE selects the maximum values of 2 PDCCH subframes and 8 PDCCH subframes, that is, starts a drx-inactivity timer with a length of 8 PDCCH subframes.
In the next period of time, when the UE receives a new PDCCH indication, the drx-InactivationTimer with the length of 8 PDCCH subframes is started until the UE receives a new MAC CE indication from the network side.
Suppose that the new MAC CE received by the UE indicates that the network side has data of LCG1 to send. So the UE starts a drx-inactivity timer with a length of 4 PDCCH subframes. During 4 PDCCH subframes, the UE does not receive any PDCCH indicating a new transmission, and thus enters a sleep period.
An embodiment of the present invention further provides a user terminal, as shown in fig. 9, including a processor 31 and a transceiver 32,
the processor 31 is configured to receive a PDCCH indication, and start one of a plurality of pre-acquired active period extension timers with different lengths.
