An embodiment of the present invention further provides another information processing method, as shown in fig. 6, the specific steps are:
step 601: a terminal receives configuration information which is sent by a wireless network node (network side) and is suitable for different logic channels, or logic channel groups, or wireless bearers;
here, the configuration information may include one or more of the following information: information of an active period extension timer, information of a short DRX cycle validity timer, information of a waiting timer before retransmission starts, information of a timer for receiving retransmission data, an indication of whether to start the active period extension timer after BSR transmission, and an indication of whether to start the short DRX cycle after BSR transmission.
The configuration information may specifically be (the following parameters are parameters already defined in the related art, but do not distinguish logical channels or logical channel groups or radio bearers):
activation period extension timer: drx-inactivytytimer;
short DRX period: drx-short cycle;
short DRX cycle validity timer: drx-ShortCycleTimer;
timer for receiving retransmission data: drx-retransmission timerdl, drx-retransmission iontimerll;
wait timer before retransmission start: drx-HARQ-RTT-TimerDL, drx-HARQ-RTT-Tim erUL;
the configuration information can be issued to the terminal in the following way:
1. the configuration is distributed to the terminal through a logic channel or a wireless bearing;
2. sending the configuration to the terminal through DRX;
3. part is sent to the terminal through DRX configuration, and part is sent to the terminal through logic channel or wireless bearing configuration.
For example: a certain configuration parameter may be issued by the DRX configuration, or by the logical channel or radio bearer configuration. Namely: the configuration parameters issued to the terminal through the logical channel or radio bearer configuration are only applicable to the corresponding logical channel or radio bearer, and the configuration parameters issued through the DRX configuration are a general numerical value and are applicable to other logical channels or radio bearers not configured with the parameters.
Wherein, the indication of whether to start the activation period extension timer after BSR transmission is that the terminal will start the activation period extension timer after BSR transmission only if the indication exists or is set to TRUE or 1.
The indication of whether to start the short DRX cycle after the BSR is transmitted may be that the terminal will adopt the short DRX cycle after the BSR is transmitted only if the indication exists, is set to TRUE, or is set to 1.
Step 602: after the terminal sends the BSR, executing the content of the configuration information corresponding to the logic channel or the logic channel group or the radio bearer;
the method specifically comprises the following steps:
after the terminal sends a BSR of a logical channel LCH/radio bearer RB, an activation period extension timer is started. During the operation period of the activation period extension timer, the terminal needs to monitor the PDCCH; or,
after the terminal sends a logic channel LCH/radio bearer RB BSR, the terminal starts a short DRX period. When the onDuration of the short DRX period comes, the terminal needs to monitor the PDCCH; or,
after the terminal sends a logic channel LCH/radio bearer RB BSR, the short DRX period effective timer is started. Before the effective timer of the short DRX period is overtime, the terminal monitors the PDCCH when the onDuration of each short DRX period arrives; or,
after the terminal sends a logical channel group LCG or BSR corresponding to a plurality of LCGs, the longest or shortest activation period extension timer in the LCHs is started. During the operation of the activation period extension timer, the terminal needs to monitor the PDCCH.
Here, when the data buffer indicated by the BSR is 0, the configuration parameters corresponding to the logical channel or the logical channel group or the radio bearer are not started.
The method may further comprise:
step 603: after transmitting the uplink data, the terminal executes the content of the configuration information corresponding to the logical channel or the logical channel group or the radio bearer.
After sending the uplink data, the terminal starts drx-HARQ-RTT-timerll corresponding to the logical channel or logical channel group or radio bearer. And after the time of drx-HARQ-RTT-TimerUL is over, starting drx-retransmission TimerUL. In the drx-HARQ-RTT-TimerUL operation period, the terminal does not need to monitor the P DCCH; during the drx-retransmission timerll operation period, the terminal needs to continuously listen to the PDCC H.
After receiving downlink data of a certain logical channel or logical channel group or radio bearer and failing in decoding, the terminal starts drx-HARQ-RTT-TimerDL corresponding to the logical channel or logical channel group or radio bearer. And after the time of the drx-HARQ-RTT-TimerDL is over, starting drx-retransmission timer DL. In the drx-HARQ-RTT-TimerDL operation period, the terminal does not need to monitor the PDCCH; during the drx-Ret ransnission timerdl operation period, the terminal needs to continuously monitor the PDCCH.
The invention is described below in connection with several scenario embodiments.
Example one
This embodiment starts a drx-inactivity timer after BSR transmission (only used after voice traffic is activated), as shown in fig. 7.
In LTE, the QCI (QoS Class Identifier) corresponding to VoLTE voice service is 1, and the QCI/QFI corresponding to IMS signaling is 5. Only after the bearer of QCI =1 or 5 is activated, the UE will be able to start the functionality of drx-inactivity timer after BSR transmission.
In this embodiment, the UE does not activate the voice service for the first period of time. That is, at this time, the configuration information may not include an indication of whether to start drx-inactivity timer after BSR transmission, or include the indication but have a value of FALSE or 0.
After the voice service bearer of the UE is established, the wireless network node retransmits the configuration information to the UE through DRX configuration. The configuration information activates the function that the UE starts drx-inactivytytytimer after BSR is sent. Thereafter, the UE starts drx-inactivity timer after sending the BSR to extend the activation time, regardless of whether the sent BSR includes the voice service buffering information. Therefore, the base station realizes the fast scheduling of the UE.
Example two
This embodiment starts a short DRX cycle validity timer (for voice traffic usage only) after BSR transmission, as shown in fig. 8.
In this embodiment, the default long DRX cycle (80 ms) is 4 times the Short DRX cycle (20 ms) corresponding to the voice LCH.
After sending the BSR (1 st BSR) not containing the LCH buffering condition of the voice service, the UE does not start a short DRX cycle, and therefore directly enters the sleep period, and does not receive the base station scheduling until entering the on Duration state again.
After sending the BSR (2 nd BSR) containing the voice service LCH buffer condition, the UE autonomously starts the short DRX cycle and DRX-short Timer (50 ms) configured for the LCH before. Therefore, the UE can wake up more quickly, and the base station can realize quick scheduling of the VoLTE voice service of the UE.

In this embodiment, a drx-inactivytytytytimer is started after BSR is sent, and different drx-inactivytimers are set for BSR sending corresponding to different LCGs, as shown in fig. 9.
The UE has multiple LCHs, which are in turn divided into different LCGs. The radio network node configures different drx-inactivity timer durations for different LCGs.
In this embodiment, LCG1 corresponds to a delay insensitive service, such as FTP type service. Therefore, the radio network node does not configure drx-inactivity timer for this type of LCH, that is, for a BSR triggered by LCG1, the UE may directly enter the sleep period after sending the BSR soon after the OnDuration is finished, and the radio network node issues a PDCCH to instruct to schedule the UE before the UE enters the OnDuration again.
LCG2 corresponds to a delay sensitive type of service, such as video service. For the BSR triggered by the LCG2, the UE starts a drx-inactivity timer with a duration of 4 PDCCH subframes after sending the BSR, and waits for the radio network node to schedule. If the radio network node does not complete scheduling within this period, the UE may enter a sleep period.
The LCG3 corresponds to a delay sensitive service, such as VoLTE service. For the BSR triggered by LCG3, the UE starts a drx-inactivytytimer with a duration of 6 PDCCH subframes after sending the BSR, so as to give more schedulable opportunities to the radio network node and complete the data transmission as soon as possible.
Example four
In this embodiment, a drx-inactivity timer is started after the BSR is sent, and only a BSR triggered by a part of LCHs starts a drx-inactivity timer, as shown in fig. 10.
The wireless network node configures a DRX-inactivity timer duration suitable for all LCHs through DRX-config, and configures each LCH with an indication of whether to start DRX-inactivity timer after BSR transmission. This indication will only be given if the LCH of drx-inactivytytimer is allowed to start after BSR transmission.
In this embodiment, the drx-inactivity timer has a length of 4 PDCCH subframes. The LCG1 does not enable the function of "starting drx-inactivytytytimer after BSR is sent" corresponding to a service insensitive to time delay, such as an FTP service. The LCG2 and the LCG3 both enable a function of "starting drx-inactivytytytimer after BSR is sent" corresponding to a delay sensitive service, such as a video service and a VoLTE service.
EXAMPLE five
This embodiment configures different drx-HARQ-RTT-timerll and drx-retransmission timerll for each LCH as shown in fig. 11.
To allow the UE to sleep during HARQ RTT (Round Trip Time), one drx-HARQ-RTT-timerll is defined per HARQ process. After the uplink data transmission of a certain HARQ process is completed, the UE may assume that there is retransmission only after the drx-HARQ-RTT-timerll subframe, so that the UE does not need to monitor the PDCCH when drx-HARQ-RTT-timerll is running. When drx-HARQ-RTT-timerll times out, the UE starts a drx-retransmission timerll for the HARQ process. When the timer is running, the UE may monitor the PDCCH for HARQ retransmission.
In this embodiment, LCH1 corresponds to a delay insensitive service, such as FTP type service. Thus, the radio network node may configure the UE with longer drx-HARQ-RTT-timerll (40 symbols) and drx-retransmission timerll (180 slots).
LCH2 corresponds to delay sensitive traffic, such as voice traffic. Therefore, the radio network node may configure the UE with a shorter drx-HARQ-RTT-timerll (20 symbols) to complete retransmission scheduling and thus data retransmission as soon as possible. It is also possible that drx-retransmission timerll (116 slots) is shorter than LCH 1.
Assuming that only LCH1 data is transmitted for the first uplink data transmission, the UE starts drx-HARQ-RTT-timerll (40 symbols) and drx-retransmission timerll (180 slots) corresponding to the LCH after transmitting the uplink data.
In order to ensure that the data of the LCH1 can be retransmitted in time, the UE starts drx-HARQ-RTT-timerll (20 symbols) and drx-retransmission timerll (116 slots) corresponding to the LCH2 after transmitting the uplink data, where the uplink data includes the data of the LCH1 and the LCH2 during the second uplink data transmission.
According to the embodiment of the invention, the network side configures the corresponding timer configuration information for the terminal, so that the terminal can monitor the PDCCH based on the timer configuration information after sending the BSR, the base station can schedule the terminal in time, the problem of delay jitter caused by the fact that the UE cannot receive base station scheduling in time in a sleep period after sending the BSR is solved, and user experience is improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
