Cross-reference to related applications

The present application claims priority to Chinese Patent Application No. 201810436364.2, filed on Jan. 9, s.

Technical field

The present disclosure relates to the field of wireless technologies, and in particular, to a method, an apparatus, a terminal, and a base station for controlling a discontinuous reception timer.

Background technique

In order to support terminal power saving, the wireless communication system introduces a discontinuous reception (DRX) mechanism. In the DRX working mode, the terminal periodically monitors the control channel, thereby achieving the purpose of power saving.

The basic principle of the DRX working mode is shown in Figure 1. The continuous monitoring On duration indicates that the user equipment (User Equipment, UE), which may also be called a terminal, monitors the time period of the control channel, during which the RF channel is opened, and the control channel is continuously monitored; except for the time other than On duration, the UE is at In the sleep state, the radio link will be turned off and the control channel will no longer be monitored to save power.

The DRX mechanism considers the arrival model of data traffic, ie the arrival of data packets is bursty. In order to adapt to this service arrival feature, the LTE DRX process uses a variety of timers and combines with the Hybrid Automatic Repeat reQuest (HARQ) process to achieve better power saving performance. Among the multiple timers of the Long Term Evolution (LTE) DRX process, the persistent watch timer On duration Timer, the uplink UL/downlink DL DRX retransmission timer DRX-Retransmission timer, and the DRX inactive timer DRX -Inactivity timer, in which any timer is running, the UE will listen to the control channel, and the time when the UE listens to the control channel is also called the activation time Active Time.

For the new air interface (NR, New Radio) system, physical downlink control channel (PDCCH) decoding/physical downlink shared channel (PDSCH) reception and DRX media access control (Media Access Control, MAC) The control unit (CE) processing takes a certain time, and the fuzzy period problem is introduced. The so-called fuzzy period problem is that the base station and the terminal do not understand whether the terminal is in the Active Time, and the base station does not know whether the terminal will send channel state information. Channel State Information (CSI) and whether the ACK/non-acknowledgement NACK and CSI are multiplexed. In addition, after the DRX-inactivity timer expires, the terminal does not monitor the PDCCH. At this time, the Interruption-Radio Network Temporary Identity (INT-RNTI) sent by the base station for notifying the interruption cannot be received, so it may be received before. The data is processed incorrectly, such as decoding the data that needs to be discarded.

In order to solve the problem that the base station and the terminal are inconsistent in understanding whether the terminal is located in the active time in the DRX working mode, the embodiment of the present disclosure provides a method for controlling the discontinuous reception timer, by causing the base station and the terminal to inactivate the DRX. The device automatically restarts to ensure the consistency between the base station and the terminal for understanding the DRX inactivity timer, thereby solving the problem that the fuzzy period is inconsistent in understanding whether it is located in the Active Time.

The control method, terminal and base station of the discontinuous reception timer provided by the embodiments of the present disclosure may be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (eLTE) system, or a subsequent evolved communication system. 2 is a schematic structural diagram of a wireless communication system according to an embodiment of the present disclosure.

The terminal 20 provided by the embodiment of the present disclosure may be a mobile phone, a tablet computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, or a Personal Digital Assistant (PDA).

One embodiment of the method for controlling a discontinuous reception timer according to an embodiment of the present disclosure is applied to a terminal. As shown in FIG. 3, in the implementation manner, the control method includes:

S310. Receive control information of a physical downlink control channel PDCCH bearer.

S320. Start a discontinuous reception DRX inactivation timer according to the control information.

S330. If the DRX inactivity timer DRX-inactivity timer expires before a preset time after receiving the control information, restart the DRX inactivity timer.

In this embodiment, after the DRX inactivity timer is started, if the terminal times out before receiving the control information sent by the PDCCH, the terminal automatically restarts the DRX inactivity timer to ensure that the base station and the terminal deactivate the DRX. The consistency of the understanding of the device enables the terminal to correctly receive messages such as CSI/ACK/NACK and avoid unnecessary blind detection.

Optionally, in the first implementation manner of the method for controlling a discontinuous reception timer according to the embodiment of the present disclosure, in step S330, an interval between the preset time and a time when the control information is received is equal to the first fixed time. The first timing interval is equal to a timing interval K0 between the control information and the physical downlink shared channel PDSCH scheduled by the control information.

Optionally, in a second implementation manner of the method for controlling a discontinuous reception timer according to the embodiment of the present disclosure, in step S330, an interval between the preset time and a time when the control information is received is equal to the first fixed time. And a second timing interval; wherein the first timing interval is equal to a timing interval K0 between the control information and a physical downlink shared channel PDSCH scheduled by the control information; the second timing interval is equal to A timing interval K1 between the PDSCH scheduled by the control information and the hybrid automatic repeat request HARQ feedback corresponding to the PDSCH.

It can be understood that three timing relationships are defined in the NR system:

K0: a timing relationship between the PDCCH and its scheduled PDSCH, that is, a timing interval K0 between the PDCCH and its scheduled PDSCH;

K1: a timing relationship between the HARQ ACK/NACK feedback corresponding to the PDSCH and the PDSCH, that is, a timing interval K1 between the PDSCH and the HARQ ACK/NACK feedback corresponding to the PDSCH;

K2: The timing relationship between the PDCCH and its scheduled Physical Uplink Shared Channel (PUSCH) transmission, that is, the timing interval K2 between the PDCCH and its scheduled PUSCH transmission.

In the first implementation manner of the method for controlling the discontinuous reception timer according to the embodiment of the present disclosure, in S330, if the DRX inactivity timer expires before the timing interval K0 arrives after receiving the control information of the PDCCH bearer, the DRX inactivity timer is restarted. DRX inactivity timer;

In the second implementation manner of the method for controlling the discontinuous reception timer according to the embodiment of the present disclosure, in S330, if the DRX inactivity timer expires before the timing interval K0+K1 arrives after receiving the control information of the PDCCH bearer, the DRX inactivity timer is restarted. DRX inactive timer.

Taking the first embodiment as an example, in conjunction with FIG. 4 and FIG. 3, the control method includes the following process:

Receiving control information carried by the PDCCH before the On duration timer expires;

According to the startup rule of the DRX-inactivity timer, the DRX-inactivity timer is started;

If the DRX-inactivity timer expires before the timing interval K0 of starting the DRX-inactivity timer control information, the DRX-inactivity timer is restarted; that is, the preset time for the DRX-inactivity timer to be restarted and the time for receiving the control information are determined. The interval between the two is equal to the first timing interval, which is equal to the timing interval K0.

Considering that the terminal needs to process the PDCCH control message for a certain period of time, during the period of processing the PDCCH control message, the terminal does not know whether the DRX-inactivity timer needs to be started. Only when the control information of the PDCCH is correctly parsed, the DRX- The inactivity timer determines the start time of the DRX-inactivity timer as the reception time of the PDCCH, so that the base station and the terminal may have inconsistent understandings on whether to start the DRX-inactivity timer from receiving the PDCCH to correctly parsing the PDCCH, and there is a ambiguity period, resulting in a fuzzy period. After the DRX-inactivity timer expires, the terminal CSI is blinded. In the above-mentioned first implementation manner, K0 is used as the monitoring time of whether the DRX-inactivity timer needs to be restarted, so that the terminal times out before the DRX inactivity timer expires before the monitoring time. The automatic restart time is extended to ensure the consistency of the DRX inactivity timer between the base station and the terminal, and the terminal CSI blind detection is avoided.

In addition, by using the foregoing first embodiment, the INT-RNTI can be sent to the terminal within the Active time by extending the Active Time of the terminal, so that the terminal can correctly process the received data to solve the related technology DRX- After the inactivity timer expires, the terminal does not monitor the PDCCH. At this time, the INT-RNTI sent by the base station cannot be received. Therefore, the previously received data may be processed incorrectly, for example, the data that needs to be discarded is decoded.

With the second embodiment, in conjunction with FIG. 5 and FIG. 3, the control method includes the following process:

If the DRX-inactivity timer expires before the timing interval K0+K1 of the DRX-inactivity timer is started, the DRX-inactivity timer is restarted; that is, the preset time for the DRX-inactivity timer to be restarted and the control information are received. The interval between times is equal to the sum of the first timing interval and the second timing interval, wherein the first timing interval is equal to the timing interval K0 and the second timing interval is equal to the timing interval K1.

Further, with the second embodiment, it is considered that the terminal needs to perform the PDSCH analysis on the PDCCH control message for a period of time. If the PDSCH carried by the PDCCH is the DRX MAC CE, the base station and the terminal start DRX-inactivity before the DRX MAC CE is parsed. If the timer is inconsistent, there is a fuzzy period. By using K0+K1 as the monitoring time of whether the DRX-inactivity timer needs to be restarted, the terminal automatically restarts when the DRX inactivity timer expires before the monitoring time, and the terminal is extended. Time time, ensuring consistency between the base station and the terminal for understanding the DRX inactivity timer, and avoiding blind detection of messages such as CSI/ACK/NACK by the terminal.

Similarly, in the second implementation manner, by extending the Active Time of the terminal, the INT-RNTI can be sent to the terminal within the Active time to ensure that the terminal can correctly process the received data to solve the related technology DRX-inactivity. After the timer expires, the terminal does not monitor the PDCCH. At this time, the INT-RNTI sent by the base station cannot be received. Therefore, the previously received data may be processed incorrectly, for example, the data that needs to be discarded is decoded.

It can be understood that, in the method for controlling the discontinuous reception timer according to the embodiment of the present disclosure, in step S330, if the DRX-inactivity timer times out before the preset time after receiving the control information, the pre- Set the DRX-inactivity timer multiple times before setting the time.

Further, the control method of the embodiment of the present disclosure, after the step S330, the method further includes:

Stopting the DRX inactivity timer at the preset time; or,

The DRX inactivity timer is stopped at the timer timeout.

Specifically, when the preset time is determined by using the first implementation manner, that is, if the DRX-inactivity timer expires before the timing interval K0 after the control information of the DRX-inactivity timer is started, the DRX-inactivity timer is restarted. The way the DRX-inactivity timer stops can be:

After the DRX-inactivity timer is restarted, it stops when the timing interval K0 arrives.

In addition, if the timer timeout time after the DRX-inactivity timer is restarted is after the time interval corresponding to the time interval K0, the manner of stopping the DRX-inactivity timer may be: stopping the DRX inactivity timer at the timer timeout time.

In addition, when the second embodiment is used to determine the preset time, that is, if the DRX-inactivity timer expires before the timing interval K0+K1 after the control information of the DRX-inactivity timer is started, the DRX-inactivity timer is restarted. The way to stop the DRX-inactivity timer can be:

After the DRX-inactivity timer is restarted, it stops when the timing interval K0+K1 arrives;

If the timer expires after the DRX-inactivity timer restarts, the DRX-inactivity timer may be stopped by stopping the DRX-inactivity timer.

The embodiment of the present disclosure further provides a method for controlling a discontinuous reception timer according to another embodiment, which is applied to a base station. As shown in FIG. 6, the method includes:

S610. Send control information of a physical downlink control channel PDCCH to the terminal.

S620. Start a discontinuous reception DRX inactivity timer corresponding to the terminal.

S630. If the DRX inactivity timer expires before a preset time after sending the control information, restart the DRX inactivity timer.

In this embodiment, after starting the DRX inactivity timer corresponding to the terminal, if the base station times out before the preset time after the PDCCH sends the control information, the base station automatically restarts the DRX inactivity timer to ensure the base station and the terminal pair DRX. The inactivity timer understands the consistency and prevents the terminal from performing unnecessary blind detection on messages such as CSI/ACK/NACK.

Optionally, in the first implementation manner of the method for controlling a discontinuous reception timer according to the embodiment of the present disclosure, in step S630, an interval between the preset time and a time when the control information is sent is equal to the first fixed time. The first timing interval is equal to a timing interval K0 between the control information and the physical downlink shared channel PDSCH scheduled by the control information.

And a second timing interval; wherein the first timing interval is equal to a timing interval K0 between the control information and a physical downlink shared channel PDSCH scheduled by the control information; the second timing interval is equal to A timing interval K1 between the PDSCH scheduled by the control information and the hybrid automatic repeat request HARQ feedback corresponding to the PDSCH.

Specifically, the timing interval K0 is a timing relationship K0 between the PDCCH defined in the NR system and its scheduled PDSCH;

The timing interval K1 is a timing relationship K1 between the PDSCH defined in the NR system and the HARQ ACK/NACK feedback corresponding to the PDSCH.

Based on the foregoing first embodiment, in S630, if the DRX inactivity timer expires before the timing interval K0 arrives after transmitting the PDCCH control information, restarting the DRX inactivity timer;

Based on the second embodiment described above, in S630, if the DRX inactivity timer expires before the timing interval K0+K1 arrives after transmitting the PDCCH control information, the DRX inactivity timer is restarted.

Specifically, when the first embodiment is used to determine the preset time, that is, if the DRX-inactivity timer expires before the timing interval K0 after the control information of the DRX-inactivity timer is started, the DRX-inactivity timer is restarted. The way the DRX-inactivity timer stops can be:

In addition, when the preset time is determined by using the second embodiment, that is, if the DRX-inactivity timer expires before the timing interval K0+K1 after the control information of the DRX-inactivity timer is started is sent, when the DRX-inactivity timer is restarted, The way to stop the DRX-inactivity timer can be:

The control method of the discontinuous reception timer according to the embodiment of the present disclosure is configured to enable the base station to automatically restart when the DRX inactivity timer expires before the monitoring time, to ensure consistency between the base station and the terminal for understanding the DRX inactivity timer. To avoid the terminal blind detection of CSI/ACK/NACK and other messages; in addition, by extending the Active Time of the base station and the terminal, the INT-RNTI can be sent to the terminal within the Active time to ensure that the terminal can correctly receive the received data. After the timeout of the DRX-inactivity timer expires, the terminal does not monitor the PDCCH. At this time, the INT-RNTI sent by the base station cannot be received.
