Description

Control method for discontinuous reception, terminal device and network side device

Technical field

The present application relates to the field of communications, and in particular, to a control method, a terminal device, and a network side device for discontinuous reception.

Background technique

In the Long Term Evolution (LTE) system, in order to save energy of user equipment (UE), a discontinuous reception (DRX) mechanism is introduced. That is, when the UE is in the connected state, it is not necessary to continuously monitor the control channel of the eNB, but intermittently monitors the control channel. The duration (On Duration) indicates the time period during which the UE listens to the control channel; except for the time other than the On Duration, the UE is in an inactive state, or the UE is in a power saving state. On Duration is periodically generated, and the specific period is implemented by the eNB configuration.

While the UE is saving power, in order to avoid excessive transmission delay between the eNB and the UE, the concept of Long DRX Cycle and Short DRX Cycle is introduced, and the UE is in a long period or a short period. Entering the inactive state, there is no need to continuously listen to the control channel of the eNB. On a short period, On Duration appears to be more frequent than a long period in a short period. If the UE is configured with both long and short periods, after the short period is started, the UE listens for a long period after the short period timer (drxShortCycleTimer) times out.

However, the current DRX command message can only stop the currently running onDurationTimer and drx-InactivityTimer, and cannot effectively implement the UE power saving when the UE has no data to send and receive.

Detailed ways

The technical solutions of the present application will be clearly and completely described in the following with reference to the specific embodiments of the present application and the corresponding drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

The technical solution of the present application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access ( WCDMA (Wideband Code Division Multiple Access), General Packet Radio Service (GPRS), Long Term Evolution (LTE), Long Term Evolution (LTE-A), NR (New Radio) Wait.

A user equipment (UE), which may also be called a mobile terminal, a mobile user equipment, or the like, may communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network). The user equipment may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket, handheld, computer built-in or in-vehicle mobile device, The wireless access network exchanges languages and/or data.

The base station may be a base station (BTS, Base Transceiver Station) in GSM or CDMA, or may be a base station (NodeB) in WCDMA, or may be an evolved base station (eNB or e-NodeB, evolutional Node B) in LTE and The 5G base station (gNB) is not limited in this application. However, for convenience of description, the following embodiments are described by taking gNB as an example.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

1 is a schematic diagram of a DRX cycle of one embodiment of the present application. As shown in FIG. 1, in the DRX mechanism, when the UE is in the connected state, it is not necessary to continuously monitor the control channel of the eNB, but intermittently monitor the control channel. The duration (On Duration) indicates the time period during which the UE listens to the control channel, in which the radio channel of the UE is turned on, and the UE continuously monitors the control channel; when the time other than the On Duration is removed, the UE is in an inactive state, or The UE is in a power-saving state. At this time, the radio link of the UE is closed.

It can also be seen from Figure 1 that there are two types of DRX cycles, namely DRX Long Cycle (Long DRX Cycle) and DRX Short Cycle (Short DRX Cycle). On Duration in the Short DRX Cycle appears to be more frequent than the Long DRX Cycle. If the UE is configured with two cycles at the same time, after the Short DRX Cycle is started, the UE listens according to the Long DRX Cycle after the DRX short cycle timer (drxShortCycleTimer) times out.

The time at which the terminal listens to the downlink channel is called the Active Time. The Active Time includes the time interval in which the following timers are running:

Duration timer (onDurationTimer): Starts at the start of the DRX long period or DRX short period and is used to monitor the timer of data transmission.

Discontinuous reception inactivity timer (drx-InactivityTimer): A timer that is used to listen for downlink data reception when it is detected that there is data transmission.

Discontinuous reception retransmission timer (drx-RetransmissionTimer): Starts after the Hybrid Automatic Repeat reQuest (HARQ) Round Trip Time (RTT) timer expires, and listens to downlink data retransmission. Timer.

Discontinuous reception uplink retransmission timer (drx-ULRetransmissionTimer): A timer that starts after the UL HARQ RTT Timer times out and listens for uplink data retransmission.

mac-ContentionResolutionTimer: Starts after mg3 transmission and listens to the timer of msg4 transmission.

Since the existing communication mechanism cannot provide an effective power saving method for the UE when there is no data transmission and reception, the present application proposes the following solution.

2 is a flow chart of a control method for discontinuous reception according to an embodiment of the present application. The method of Figure 2 is performed by a network side device. It should be understood that the specific product form of the network side device may be, for example, a base station or the like. The method of Figure 2 can include:

It should be understood that the first timer may be a discontinuous reception retransmission timer (drx-RetransmissionTimer), which is a Hybrid Automatic Repeat reQuest (HARQ) Round Trip Time (RTT) timer. (Timer) starts after timeout and listens to the timer of downlink data retransmission.

It should be understood that the second timer may be a discontinuous reception uplink retransmission timer (drx-ULRetransmissionTimer), which is started after the uplink UL HARQ RTT Timer times out, and monitors the timer of the uplink data retransmission.

It should be understood that the third timer may be a media access control connection competition solution timer (mac-ContentionResolutionTimer), which is started after the mg3 transmission and is used to monitor the timer of the msg4 transmission.

It should be understood that the fourth timer may be a DRX long period duration timer (onDurationTimer), which is initiated at the beginning of the DRX long period for listening for data transmission. The fourth timer is also called drxLongCycleTimer.

It should be understood that the fifth timer may be a DRX short cycle duration timer (onDurationTimer) that is initiated at the beginning of the DRX short cycle for listening for data transmission. The fifth timer is also called drxShortCycleTimer.

Of course, it should be understood that before step S201, the method may further comprise the step of generating a transmission DRX indication information or determining a resource location for indicating the DRX indication information.

In addition, it should be understood that the DRX indication information may include indication information for instructing to stop the onDurationTimer and/or the discontinuous inactivity timer (drx-InactivityTimer) in the current DRX cycle, in addition to the above indication content. Among them, drx-InactivityTimer, which is started when listening to data transmission, is used to monitor downlink data reception.

Of course, it should be understood that, among the at least one type of indication information included in the DRX indication information, the indication information of the control operations of different timers may be the same or different.

For example, suppose the DRX indication information is 3 bits in length, wherein the first bit is used to indicate a control operation on the first timer, and the second bit is used to indicate a control operation on the second timer and the fourth timer, The third bit is used to indicate control operations on the third timer and the fifth timer, and the like. Specifically, for example, 010, it may indicate that the first timer in the current DRX cycle is stopped, the second timer in the current DRX cycle is not stopped, the third timer in the current DRX cycle is stopped, and the current DRX cycle is not blocked. A fourth timer in a number of DRX long cycles is initiated, preventing a fifth timer in a number of DRX short cycles after the current DRX cycle from starting, and so on.

Optionally, as a further embodiment, step S201 is specifically implemented as:

Transmitting the DRX indication information by transmitting a DRX COMMAND message on the PDCCH resource, where the location of the PDCCH resource for transmitting the DRX COMMAND message and the indication information carried by the DRX COMMAND message are used for joint indication pair and activation time Related timer control operations.

Further, when the DRX indication information is used to block the indication information of the fourth timer in the at least one DRX long period after the current DRX period, the DRX indication information is further used to indicate the number of the at least one DRX long period. .

Further, when the DRX indication information is used to block the indication information of the fifth timer in the at least one DRX short period after the current DRX period, the DRX indication information is further used to indicate the number of the at least one DRX short period. .

Hereinafter, the method of the embodiment of the present application will be further described in conjunction with specific embodiments.

3 is a flow chart of a control method for discontinuous reception according to an embodiment of the present application. The gNb of the embodiment shown in FIG. 3 is a specific product form of the network side device of the present application, and the UE of the embodiment shown in FIG. 3 is a specific product form of the terminal device of the present application. The method can include:

301. The base station sends the DRX indication information.

In the embodiment of the present application, the DRX indication information is used to indicate a control operation on a timer related to an activation time, and may include the following indication information:

The indication information for stopping the drx-RetransmissionTimer in the current DRX cycle;

The indication information for stopping the drx-ULRetransmissionTimer in the current DRX period, where the second timer is a timer for monitoring uplink data retransmission;

The indication information for stopping the mac-ContentionResolutionTimer in the current DRX cycle, the third timer is used for monitoring the transmission of the message 4;

An indication for preventing the onDurationTimer of at least one DRX long period after the current DRX cycle from starting;

An indication for blocking the start of the onDurationTimer of at least one DRX short period after the current DRX cycle.

Of course, it should be understood that the DRX indication information may further include indication information for stopping the onDurationTimer within the current DRX cycle, and/or indication information for stopping the drx-InactivityTimer within the current DRX cycle.

In the embodiment of the present application, the DRX indication information may be sent by using at least the following three manners.

Optionally, in the first mode, the gNb may send a DRX COMMAND message, where the DRX COMMAND message carries the DRX indication information.

For example, the above five kinds of indication information can be represented by 5 bits. Specifically, it can be used for 0 to stop or block the corresponding timer, 1 for maintaining the timer or starting the timer, or vice versa. The first indication bit can be used to indicate whether to stop the drx-RetransmissionTimer in the current DRX cycle, the second indication bit can be used to indicate whether to stop the drx-ULRetransmissionTimer in the current DRX cycle, and the third indication bit is used to indicate whether Stopping the indication information of the mac-ContentionResolutionTimer in the current DRX cycle, the fourth indication bit is used to indicate whether to prevent the onDurationTimer of at least one DRX long period after the current DRX cycle from starting, and the fifth indication bit is used to indicate whether to block the current DRX At least one DRX short cycle onDurationTimer is started after the cycle, and so on.

Certainly, it should be understood that the above is only one possible information representation manner of the DRX indication information. In an actual application, the DRX indication information may only indicate several types of control operations of the above five types of timers, and the DRX indication information. One of the indicator bits may indicate a control operation of one or more timers, the DRX indication information may jointly indicate the control operation of one or more timers through a plurality of indicator bits, and the like.

Optionally, in the second mode, the gNb may send a downlink signal of a specified type on the PDCCH resource, where the location of the PDCCH resource used to send the downlink signal of the specified type is indicated by the DRX indication information. There is a mapping relationship between the control operations of the timers related to the activation time. In other words, there is a mapping relationship between the PDCCH resource location and the DRX indication information.

The downlink signal of the specified type may be multiple, for example, it may be Downlink Control Information (DCI), or Channel State Information (CSI), and the like.

In this embodiment of the present application, a mapping relationship between a PDCCH resource location and a control operation of a timer related to an activation time may be established.

Of course, it should be understood that the PDCCH resource location may include a frequency domain resource location and/or a time domain resource location of the PDCCH.

Taking the frequency domain resource location as an example, for example, the mapping relationship may include: transmitting a downlink signal on the subcarrier 1 to stop the RetransmissionTimer in the current DRX cycle, and transmitting a downlink signal on the subcarrier 2 to stop the drx-ULRetransmissionTimer in the current DRX cycle. The mac-ContentionResolutionTimer transmits a downlink signal on the subcarrier 3 to indicate that the onDurationTimer of at least one DRX long period after the current DRX cycle is prevented and the onDurationTimer of at least one DRX short period after the current DRX cycle is started, and so on.

The manner of controlling the operation of the timer by the frequency domain resource location and the time domain resource location, and the manner of controlling the operation by the time domain resource location indication timer may refer to the manner of controlling the operation by the frequency domain resource location indication timer, and will not be described again. .

Optionally, in a third mode, the gNb may send a DRX COMMAND message on the PDCCH resource, where the location of the PDCCH resource used to send the DRX COMMAND message, and the indication information carried by the DRX COMMAND message, Used to jointly indicate control operations on timers associated with activation time.

For example, the DRX COMMAND carries the indication bit 0, and the subcarrier that transmits the DRX COMMAND is 1, the joint indicates that the RetransmissionTimer in the current DRX cycle is stopped; the DRX COMMAND carries the indication bit 1, and the subcarrier that transmits the DRX COMMAND is 1, the joint indicates that the current stop is The drx-ULRetransmissionTimer in the DRX cycle; the DRX COMMAND carries the indication bit 0, and the subcarrier that transmits the DRX COMMAND is 0, the joint indicates that the mac-ContentionResolutionTimer in the current DRX cycle is stopped, and so on.

302. The UE performs a control operation on a timer related to an activation time indicated by the DRX indication information.

After receiving the DRX indication information, the UE may perform a control operation on the timer related to the activation time indicated by the DRX indication information according to the DRX indication information. Specifically, it includes:

If the indication information for stopping the drx-RetransmissionTimer in the current DRX cycle is received, stopping the drx-RetransmissionTimer in the current DRX cycle;

Stopping the drx-ULRetransmissionTimer in the DRX cycle if receiving the indication information for stopping the drx-ULRetransmissionTimer in the current DRX cycle;

If receiving the indication information for stopping the mac-ContentionResolutionTimer in the current DRX cycle, stopping the mac-ContentionResolutionTimer in the current DRX cycle;

Blocking initiation of the onDurationTimer of the at least one DRX long period after the current DRX cycle if receiving indication information for blocking initiation of the atDurationTimer of at least one DRX long period after the current DRX cycle;

The activation of the onDurationTimer of the at least one DRX short cycle after the current DRX cycle is blocked if the indication information for blocking the start of the onDurationTimer of at least one DRX short cycle after the current DRX cycle is received.

Of course, it should be understood that, according to the manner in which the gNb sends the DRX indication information in the step 301, the UE may obtain the DRX indication information in a corresponding manner.

For the first mode, the UE may directly obtain the DRX indication information from the received information.

For the second mode, the UE may blindly detect the location of the PDCCH resource of the specified type of downlink signal (including the frequency domain resource location and/or the time domain resource location), and then according to the PDCCH resource location and the timer related to the activation time. The mapping relationship of the control operations determines the control operation of the timer related to the activation time, or determines the DRX indication information according to the mapping relationship between the PDCCH resource location and the DRX indication information.

For the third mode, the UE may obtain the first part information of the DRX indication information from the received information, and obtain the location of the PDCCH resource (including the frequency domain resource location and/or the time domain resource location) of the downlink signal of the specified type by using the blind detection. That is, the second part of the information of the DRX indication information; and then the control operation of the timer related to the activation time is determined and executed according to the first part information of the DRX indication information and the second part information of the DRX indication information.

Of course, it should be understood that before step S301, gNb and the UE may pre-agreed the manner of transmitting the DRX indication information.

In addition, it should be understood that when the DRX indication information is used to block the indication information of the onDurationTimer initiated by the at least one DRX long period after the current DRX period, the DRX indication information is further used to indicate the number of the at least one DRX long period.

The DRX indication information is further used to indicate the number of the at least one DRX short period when the DRX indication information is used to block the indication information of the onDurationTimer activation of at least one DRX short period after the current DRX period.

Furthermore, it should be understood that in steps 301 and 302 above, the DRX indication information is also used to stop the onDurationTimer and/or drx-InactivityTimer within the current DRX cycle.

The control operation of the timer can stop the operation of some timers in the UE, and effectively realize the power saving of the UE when there is no data transmission and reception.
