Description

Control method, device, terminal and base station of discontinuous reception timer
Technical Field
The present invention 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
To support terminal power saving, the wireless communication system introduces a Discontinuous Reception (DRX) mechanism. In the DRX operation mode, the terminal periodically monitors the control channel, thereby saving power.
The basic principle of the DRX operation mode is shown in fig. 1. Wherein, continuously monitoring the On duration represents User Equipment (UE), which may also be called a terminal, and monitors a time period of a control channel, during which a radio frequency channel is opened and the control channel is continuously monitored; at other times except the On duration, the UE is in a Sleep state, the radio frequency link is closed, and the UE does not monitor the control channel any more, so as to achieve the purpose of saving power.
The DRX mechanism takes into account the arrival model of data traffic, i.e. the arrival of data packets is bursty. In order to adapt to the service arrival characteristics, the LTE DRX process employs multiple timers and is combined with a Hybrid Automatic Repeat reQuest (HARQ) process to achieve better power saving performance. Among various timers in the Long Term Evolution (LTE) DRX process, for a continuous monitoring Timer On duration Timer, an uplink UL/downlink DL DRX Retransmission Timer DRX-Retransmission Timer, and a DRX Inactivity Timer DRX-Inactivity Timer, any one of the timers is running, the UE will monitor a control channel, wherein the Time for which the UE monitors the control channel is also called an Active Time.
For a New air interface (NR, New Radio) system, a certain Time is required for receiving a Physical Downlink Control Channel (PDCCH)/decoding a Physical Downlink Shared Channel (PDSCH) and processing a DRX Media Access Control (MAC) Control Element (CE), and a problem of an ambiguity period is introduced, where the ambiguity period is that whether a base station and a terminal are in Active Time understanding inconsistency, and the base station does not know whether the terminal sends Channel State Information (CSI) and whether acknowledgement/ACK non-acknowledgement NACK and CSI are multiplexed. In addition, after the DRX-inactivity timer expires, the terminal does not monitor the PDCCH any more, and cannot receive a Radio Network Temporary Identity (INT-RNTI) sent by the base station for notifying the Interruption at this time, so that error processing may be performed on the previously received data, for example, the data that needs to be discarded is decoded.

The control method, the terminal and the base station of the discontinuous reception timer provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system. Fig. 2 is a schematic diagram of a wireless communication system according to an embodiment of the present invention. As shown in fig. 2, the wireless communication system may include a base station 10 and a terminal 20, and the connection actually applied between the base station 10 and the terminal 20 may be a wireless connection, and is illustrated by a solid line in fig. 2 for the convenience of intuitively representing the connection relationship between the respective devices.
It should be noted that the communication system may include a plurality of terminals 20, and the base station may communicate (transmit signaling or transmit data) with the plurality of terminals.
The base station 10 provided in the embodiment of the present invention may be a commonly used base station, an evolved node base station (eNB), or a network side device in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), or a cell, and the like.
The terminal 20 provided in the embodiment of the present invention may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or the like.
One of the embodiments of the method for controlling a discontinuous reception timer according to the embodiment of the present invention is applied to a terminal, as shown in fig. 3, in this embodiment, the method includes:
s310, receiving control information carried by a Physical Downlink Control Channel (PDCCH);
s320, starting a Discontinuous Reception (DRX) inactivity timer according to the control information;
s330, if the DRX-inactivity timer is overtime before the preset time after the control information is received, restarting the DRX-inactivity timer.
In this embodiment, after the terminal starts the DRX inactivity timer, if the terminal times out before the preset time after receiving the control information sent by the PDCCH, the DRX inactivity timer is automatically restarted to ensure consistency of understanding by the base station and the terminal on the DRX inactivity timer, so that the terminal can correctly receive the CSI/ACK/NACK and other messages, and avoid unnecessary blind detection.
Optionally, in a first implementation manner of the method for controlling a drx timer according to the embodiment of the present invention, in step S330, an interval between the preset time and the time for receiving the control information is equal to a first fixed time interval, where the first fixed time interval is equal to a timing interval K0 between the control information and a PDSCH of a physical downlink shared channel scheduled by the control information.
Optionally, in a second implementation manner of the control method of the discontinuous reception timer according to the embodiment of the present invention, in step S330, an interval between the preset time and the time for receiving the control information is equal to a sum of a first timing interval 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 a PDSCH scheduled by the control information and a hybrid automatic repeat request (HARQ) feedback corresponding to the PDSCH.
It is understood that three timing relationships are defined in the NR system:
k0: the timing relationship between the PDCCH and its scheduled PDSCH, i.e. there is a timing interval K0 between the PDCCH and its scheduled PDSCH;
k1: the timing relationship between the HARQ ACK/NACK feedbacks corresponding to the PDSCH and the PDSCH, that is, the timing interval K1 is provided between the HARQ ACK/NACK feedbacks corresponding to the PDSCH and the PDSCH;
k2 timing relationship between PDCCH and its scheduled Physical Uplink Shared Channel (PUSCH) transmission, i.e. there is a timing interval K2 between PDCCH and its scheduled PUSCH transmission.
When the first implementation manner of the control method of the discontinuous reception timer according to the embodiment of the present invention is adopted, in S330, if the DRX inactivity timer is overtime after receiving the control information carried by the PDCCH and before the timing interval K0 arrives, the DRX inactivity timer is restarted;
when the second implementation manner of the control method of the discontinuous reception timer according to the embodiment of the present invention is adopted, in S330, if the DRX inactivity timer times out before the timing interval K0+ K1 arrives after receiving the control information carried by the PDCCH, the DRX inactivity timer is restarted.
As an example of the first embodiment, with reference to fig. 4 and 3, the control method includes the following steps:
receiving control information carried by the PDCCH before the On duration Timer is overtime;
starting the DRX-inactivity timer according to the starting rule of the DRX-inactivity timer;
restarting the DRX-inactivity timer if the DRX-inactivity timer times out before a timing interval K0 of starting control information of the DRX-inactivity timer; i.e. the interval between the preset time of determining whether the DRX-inactivity timer needs to be restarted and the time of receiving the control information is equal to the first timing interval, which is equal to the timing interval K0.
Considering that a terminal needs a certain Time for processing a PDCCH control message, the terminal does not know whether a DRX-inactivity timer needs to be started or not in the period of processing the PDCCH control message, the DRX-inactivity timer is started only after control information of the PDCCH is correctly analyzed, and the starting Time of the DRX-inactivity timer is determined as the receiving Time of the PDCCH, so that understanding of the base station and the terminal on whether the DRX-inactivity timer is started or not is possibly inconsistent from the receiving of the PDCCH to the correctly analyzing of the PDCCH, a fuzzy period exists, and blind detection of terminal CSI after the DRX-inactivity timer is overtime is caused, the first embodiment is adopted, K0 is used as monitoring Time for judging whether the DRX-inactivity timer needs to be restarted or not, the terminal is automatically restarted before the monitoring Time, the overtime Time of the terminal is prolonged, and the understanding consistency of the base station and the DRX-inactivity timer is ensured, and avoiding blind detection of the terminal CSI.
In addition, by prolonging the Active Time of the terminal, the first embodiment ensures that INT-RNTI can be issued to the terminal within the Active Time, and ensures that the terminal can correctly process the received data, so as to solve the problem that the terminal cannot receive INT-RNTI sent by the base station and cannot monitor PDCCH any more after the DRX-inactivity timer in the prior art is overtime, and therefore the previously received data may be processed incorrectly, for example, the data to be discarded is decoded.
When the second embodiment is adopted, with reference to fig. 5 and 3, the control method includes the following processes:
receiving control information carried by the PDCCH before the On duration Timer is overtime;
starting the DRX-inactivity timer according to the starting rule of the DRX-inactivity timer;
restarting the DRX-inactivity timer if the DRX-inactivity timer times out before a timing interval K0+ K1 of control information for starting the DRX-inactivity timer; i.e. the interval between the preset time of determining whether the DRX-inactivity timer needs to be restarted and the time of receiving the control information is equal to the sum of a first timing interval equal to the timing interval K0 and a second timing interval equal to the timing interval K1.
Further, by adopting the second embodiment, considering that a period of Time is required for a terminal to analyze a PDSCH carried by a PDCCH control message, if the PDSCH carried by the PDCCH is a DRX MAC CE, before the DRX MAC CE is analyzed, the base station and the terminal understand that whether the DRX-inactivity timer is started or not is inconsistent, and a fuzzy period exists, the terminal is automatically restarted under the condition that the DRX inactivity timer is overtime before the monitoring Time by taking K0+ K1 as the monitoring Time whether the DRX-inactivity timer is required to be restarted or not, the Active Time of the terminal is prolonged, the consistency of understanding of the base station and the terminal to the DRX inactivity timer is ensured, and the terminal is prevented from blindly detecting messages such as CSI/ACK/NACK.
Similarly, by prolonging the Active Time of the terminal, the second embodiment ensures that the INT-RNTI can be issued to the terminal within the Active Time, and ensures that the terminal can correctly process the received data, so as to solve the problem that the terminal cannot receive the INT-RNTI sent by the base station and no longer monitors the PDCCH after the DRX-inactivity timer in the prior art is overtime, and therefore the previously received data may be processed incorrectly, for example, the data to be discarded is decoded.
It can be understood that, in the method for controlling a DRX-inactivity timer according to the embodiment of the present invention, in step S330, if the DRX-inactivity timer times out a plurality of times before the preset time after receiving the control information, the DRX-inactivity timer may be restarted a plurality of times before the preset time.
Further, after step S330, the control method according to the embodiment of the present invention further includes:
stopping a DRX inactivity timer at the preset time; alternatively, the first and second electrodes may be,
the DRX inactivity timer is stopped at the timer timeout time.
Specifically, when the first embodiment is adopted for determining the preset time, that is, if the DRX-inactivity timer times out before the timing interval K0 after the DRX-inactivity timer is started to receive the control information of the DRX-inactivity timer, the method for stopping the DRX-inactivity timer when the DRX-inactivity timer is restarted may be as follows:
the DRX-inactivity timer is restarted and then stopped when the timing interval K0 arrives.
If the timer timeout time after the restart of the DRX-inactivity timer is after the time corresponding to the timer interval K0, the DRX-inactivity timer may be stopped by: the DRX inactivity timer is stopped at the timer timeout time.
In addition, when the second embodiment is adopted for determining the preset time, that is, if the DRX-inactivity timer times out before the timing interval K0+ K1 after the reception of the control information for starting the DRX-inactivity timer, the manner of stopping the DRX-inactivity timer when restarting the DRX-inactivity timer may be:
stopping the DRX-inactivity timer at a timing interval K0+ K1 after the DRX-inactivity timer is restarted;
if the timer timeout time after the restart of the DRX-inactivity timer is after the time corresponding to the timing interval K0+ K1, the manner of stopping the DRX-inactivity timer may be: the DRX inactivity timer is stopped at the timer timeout time.
An embodiment of the present invention further provides a method for controlling a drx timer according to another embodiment, where the method is applied to a base station, and as shown in fig. 6, the method includes:
s610, sending control information of a Physical Downlink Control Channel (PDCCH) to a terminal;
s620, starting a Discontinuous Reception (DRX) inactivity timer corresponding to the terminal;
and S630, if the DRX inactivity timer is overtime before the preset time after the control information is sent, restarting the DRX inactivity timer.
In this embodiment, after the base station starts the DRX inactivity timer corresponding to the terminal, if the DRX inactivity timer is overtime before the preset time after the control information is sent by the PDCCH, the DRX inactivity timer is automatically restarted, so as to ensure the consistency of understanding by the base station and the terminal on the DRX inactivity timer, and avoid the terminal from generating unnecessary blind detection on messages such as CSI/ACK/NACK and the like.
Optionally, in the first implementation manner of the method for controlling a drx timer according to the embodiment of the present invention, in step S630, an interval between the preset time and the time for transmitting the control information is equal to a first fixed time interval, where the first fixed time interval is equal to a timing interval K0 between the control information and a PDSCH of a physical downlink shared channel 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 invention, in step S630, an interval between the preset time and the time for sending the control information is equal to a sum of a first timing interval 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 a PDSCH scheduled by the control information and a 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 the PDSCH scheduled by the PDCCH;
the timing interval K1 is the timing relationship K1 between HARQ ACK/NACK feedbacks corresponding to PDSCH and PDSCH defined in the NR system.
Based on the first embodiment, in S630, if the DRX inactivity timer times out before the timing interval K0 is reached after the PDCCH control information is sent, the DRX inactivity timer is restarted;
based on the second embodiment, in S630, if the DRX inactivity timer times out before the timing interval K0+ K1 arrives after the PDCCH control information is transmitted, the DRX inactivity timer is restarted.
Specific exemplary processes using the above two embodiments can be combined with those shown in fig. 4 and 5, and will not be described in detail here.
Further, after step S630, the control method according to the embodiment of the present invention further includes:
stopping a DRX inactivity timer at the preset time; alternatively, the first and second electrodes may be,
the DRX inactivity timer is stopped at the timer timeout time.
Specifically, when the first embodiment is adopted for determining the preset time, that is, if the DRX-inactivity timer times out before the timing interval K0 after the DRX-inactivity timer is started to send the control information of the DRX-inactivity timer, the method for stopping the DRX-inactivity timer when the DRX-inactivity timer is restarted may be as follows:
the DRX-inactivity timer is restarted and then stopped when the timing interval K0 arrives.
If the timer timeout time after the restart of the DRX-inactivity timer is after the time corresponding to the timer interval K0, the DRX-inactivity timer may be stopped by: the DRX inactivity timer is stopped at the timer timeout time.
In addition, when the second embodiment is adopted for determining the preset time, that is, if the DRX-inactivity timer times out before the timing interval K0+ K1 after the DRX-inactivity timer is started to send the control information of the DRX-inactivity timer, the method for stopping the DRX-inactivity timer when the DRX-inactivity timer is restarted may be as follows:
stopping the DRX-inactivity timer at a timing interval K0+ K1 after the DRX-inactivity timer is restarted;
