Detailed Description
As will be appreciated by those skilled in the art, as mentioned in the background, it is difficult for NTN communication to take advantage of DRX power saving directly by using the DRX scheme in the prior art.
The inventor of the present application finds, through research, that in 5G NR communication, a network may configure a Discontinuous Reception (DRX) mode for a User Equipment (UE) in a connected state. The UE in the DRX mode does not need to continuously receive a Physical Downlink Control Channel (PDCCH for short).
Specifically, when the connected UE is in DRX mode, the parameters and characteristics are as follows:
(1) discontinuous reception duration timer (drx-onDurationTimer): from the starting slot of the DRX cycle (DRX cycle), the UE fixes the time in active state (active). During the timer drx onDurationTimer operation, the UE is in the active state and can monitor the PDCCH.
Wherein the onDuration time of different UEs is different, the sub-frame at the beginning of the DRX period and the time slot in the sub-frame of the discontinuous reception time slot offset (DRX-SlotOffset) are indicated by the discontinuous reception start offset (DRX-StartOffset).
(2) Discontinuous reception inactivity timer (drx-inactivity timer): a duration after the PDCCH monitoring time, where the PDCCH is used to instruct a Multimedia Access Control (MAC) entity (entity) to perform new Uplink (UL) transmission or Downlink (DL) transmission. Each time PDCCH Downlink Control Information (DCI) indicating uplink and Downlink is received, the UE starts or restarts the timer drx-inactivity timer. During the running of the timer drx-inactivity timer, the UE continuously monitors the PDCCH.
Taking fig. 1 as an example, during OnDuration in one DRX cycle, the UE remains active and starts or restarts the timer DRX-inactivity timer each time DCI indicating uplink and downlink transmission is received. During the timer drx-inactivity timer activity, the UE continues to remain active.
(3) DL discontinuous reception Hybrid Automatic Repeat reQuest (HARQ for short) RTT timer (drx-HARQ-RTT-TimerDL): for each DL HARQ process, the MAC entity expects a shortest duration before allocating a DL configuration (assignment) for HARQ retransmission. The UE starts the timer drx-HARQ-RTT-TimerDL after receiving DL data and sending DL data Acknowledgement (ACK) on a Physical Uplink Control Channel (PUCCH). Since the base station needs processing time for processing data and propagation time for transmitting data, the network does not retransmit DL data or transmit new DL data for the UE during the timer drx-HARQ-RTT-TimerDL activity (active).
(4) UL discontinuous reception HARQ RTT timer (drx-HARQ-RTT-timerll): for each UL HARQ process, the MAC entity expects a shortest duration before allocating UL configuration for HARQ retransmissions. The UE starts the timer drx-HARQ-RTT-timerll after transmitting UL data. Since the base station needs processing time for processing data and propagation time for transmitting data, the base station does not perform HARQ feedback on the UL data of the UE during the active period of the timer drx-HARQ-RTT-timerll.
(5) DL discontinuous reception retransmission timer (drx-retransmission timerdl): for each DL HARQ process, until a maximum duration of DL retransmission is received. If the timer drx-HARQ-RTT-TimerDL times out, the timer drx-RecransmissionTimerDL is started. During the timer drx-retransmission timerdl activity, the UE remains active to receive data blocks that the base station may retransmit to the UE or newly transmitted data blocks.
(6) UL discontinuous reception retransmission timer (drx-retransmission timer UL): for each UL HARQ process, until a maximum duration of UL retransmission is received. If the timer drx-HARQ-RTT-TimerUL times out, the timer drx-RecransmissionTimerUL is started. During the timer drx-retransmission timerrul activity, the UE remains active to receive HARQ feedback for a corresponding UL data block that the base station may send to the UE and allocate uplink data transmission resources.
Generally, data transmission and reception in the DRX mode is a balance between power consumption and response speed of a connected UE. After the frequency of transmitting and receiving data is reduced, the UE is generally configured to enter into the DRX mode.
The current DRX mechanism is designed aiming at the communication characteristic of the land network, and because the air propagation delay of signals is very short and is only several microseconds to dozens of microseconds, the RTT time of the land network is relatively short. The delay in land network communications is mainly due to processing delays, typically a few milliseconds.
However, RTT of NTN communication is long, and air propagation delay of its signal may reach tens of milliseconds, even hundreds of milliseconds. If the various timers and parameters in the current DRX mechanism are directly applied to NTN communication, the following problems arise: because the timer drx-HARQ-RTT-TimeRIL or the timer drx-HARQ-RTT-TimerDL is larger, the UE leaves the active state probably when the timeout is over. According to the DRX mechanism of land-network communication, the UE in DRX mode needs to wake up and start a timer DRX-retransmission timerll or a timer DRX-retransmission timerdl, and before the timer DRX-retransmission timerll or the timer DRX-retransmission timerdl expires, the UE is in an active (also called active) state.
Referring to fig. 2, when the connected UE is in DRX mode, the UE needs to remain active and receive a UL grant (UL grant) for the duration of the on duration of the DRX cycle to complete UL transmission. Thereafter, the UE may leave the active state (e.g., enter the inactive state) during the timer DRX-HARQ-RTT-timerll operation, and after the timer DRX-HARQ-RTT-timerll expires, the UE re-enters the active state and starts the timer DRX-retransmission timerll. Further, during the operation of the timer drx-retransmission timerll, the UE may receive the retransmission UL grant and complete UL retransmission.
Normally, the UE leaves the active state and needs to complete a series of actions. Otherwise, the UE enters the active state and still needs to complete a series of actions. Since the device needs a period of time to stabilize, when the UE enters the active state, the clock frequency needs to be switched in advance to complete a series of actions. In NTN communication, the duration of the timer drx-HARQ-RTT-timerll or the timer drx-HARQ-RTT-TimerDL increases due to the long RTT time. After the timer drx-HARQ-RTT-TimeRIL or the timer drx-HARQ-RTT-TimerDL times out, the UE probably leaves the active state. At this time, if the UE transitions from the inactive state to the active state to receive the retransmission UL grant, it is not beneficial to save the power consumption of the terminal.
To solve the above technical problem, an embodiment of the present invention provides a method for controlling UE discontinuous reception, including: in a connected state, after a discontinuous reception HARQ round-trip time timer is overtime, whether the HARQ round-trip time timer is in an inactive state is determined; when the mobile station is in the inactive state, the mobile station keeps the inactive state and does not start the discontinuous reception retransmission timer. Through the technical scheme provided by the embodiment of the invention, if the UE in the DRX mode enters the inactive state after the timer for the round trip time of the discontinuous reception HARQ is overtime, the NTN communication characteristic can be effectively matched (for example, the RTT time is generally several milliseconds to hundreds of milliseconds), the UE is allowed to continuously keep the inactive state, a series of actions of switching from the inactive state to the active state are avoided, the power consumption of the terminal can be greatly saved, and the power saving advantage of the DRX is effectively exerted.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 3 is a flowchart illustrating a method for controlling discontinuous reception of a UE according to an embodiment of the present invention. The control method is suitable for the connected UE in the DRX mode so as to effectively save the power consumption of the terminal.
Specifically, the method for controlling discontinuous reception of the UE may include the steps of:
step S101, in a connection state, after a discontinuous reception HARQ round-trip time timer is overtime, whether the HARQ round-trip time timer is in an inactive state is determined;
and step S102, when the mobile terminal is in the inactive state, the mobile terminal keeps the inactive state and does not start the discontinuous reception retransmission timer.
More specifically, a network (e.g., a base station) may configure a DRX mode for a connected UE (e.g., a MAC entity) through Radio Resource Control (RRC) signaling, so that the UE may save power consumption of the terminal through DRX when transmitting delay-insensitive traffic.
Further, the base station may configure a timer drx-HARQ-RTT-timerll or a timer drx-HARQ-RTT-TimerDL for the UE. The difference from the prior art is that when the timer drx-HARQ-RTT-timerll or the timer drx-HARQ-RTT-TimerDL times out, if the UE has left the active state, the UE does not need to start the timer drx-retransmission timerll or the timer drx-retransmission TimerDL and enter the active state.
Further, for the UE, in step S101, when the UE in the DRX mode communicates with the base station, if the UE transmits uplink data to the base station, the UE starts a timer DRX-HARQ-RTT-timerll. Due to the long RTT in NTN communication, the timer DRX-HARQ-RTT-timerll timing time is extended, and then the UE enters an inactive state at a high probability to save power consumption. After the timer DRX-HARQ-RTT-TimerUL times out, the UE can judge whether the UE is in an active state or an inactive state.
As an example of a variation, when a UE in DRX mode communicates with a base station, if the UE receives downlink data transmitted by the base station, the UE will start a timer DRX-HARQ-RTT-TimerDL. Due to the long RTT in the NTN communication, the timing time of the timer DRX-HARQ-RTT-TimerDL is also correspondingly extended, which further causes the UE to enter an inactive state at a high probability to save power consumption. After the timer DRX-HARQ-RTT-TimerDL times out, the UE can judge whether the UE is in an active state or an inactive state.
In step S102, considering that the service of the UE entering the DRX mode has low requirement on response speed in NTN communication, to save energy consumption, the UE may not start the timer DRX-retransmission timerll or the timer DRX-retransmission timerll in the current DRX cycle when the timer DRX-HARQ-RTT-timerls or the timer DRX-HARQ-RTT-timerls is out of the active state and the UE has left the active state.
If the UE is in the inactive state after the timer DRX-HARQ-RTT-timerll expires, the UE may not start the timer DRX-retransmission timerll in the current DRX cycle to continue to maintain the active state.
Further, the UE may remain inactive for the current DRX cycle until the next DRX cycle is due. And receiving a retransmission UL grant during the OnDuration period of the next DRX period, and carrying out UL retransmission according to the UL grant.
Specifically, as a non-limiting example, referring to fig. 4, during a current DRX cycle (e.g., DRX cycle 1), the UE may receive a UL grant during OnDuration. Whenever the UE receives DCI indicating UL data transmission, the UE will start or restart a timer drx-inactivity timer (not shown), and during the time that the timer drx-inactivity timer is active, the UE continues to remain active.
Further, when the UE transmits uplink data, the timer drx-HARQ-RTT-timerll is started. When the timer drx-HARQ-RTT-TimerUL is overtime and the UE leaves the activated state, the UE does not start the timer drx-retransmission TimerUL any more, namely the UE is allowed not to immediately turn into the activated state, and the base station does not immediately configure the UE for the UL grant for uplink transmission and does not immediately transmit new data.
Further, the UE may receive the PDCCH at a next DRX cycle (e.g., DRX cycle 2) adjacent to the current DRX cycle (e.g., DRX cycle 1). For example, when DRX cycle 2 comes, the UE may receive a PDCCH on which an uplink grant for UL retransmission or new UL transmission is located during OnDuration of DRX cycle 2 and perform UL retransmission.
Those skilled in the art will appreciate that fig. 4 shows two DRX cycles (including DRX cycle 1 and DRX cycle 2), with the remaining DRX cycles indicated by ellipses (…). In practical applications, the DRX cycle may continue to extend in the time domain.
As another non-limiting example, after the UE receives DL data and sends a DL data acknowledgement on a Physical Uplink Control Channel (PUCCH), the UE may start a timer drx-HARQ-RTT-TimerDL. When the timer drx-HARQ-RTT-TimerDL expires and the UE has left the active state, the UE may not start the timer drx-retransmission TimerDL. That is, the UE is allowed not to immediately transition to the active state, and the base station immediately configures a DL grant for downlink transmission for the UE, and does not immediately receive new downlink data.
Further, the UE may receive the PDCCH in a next DRX cycle adjacent to the current DRX cycle. For example, when the next DRX cycle comes, the UE may receive, in the next DRX cycle, a PDCCH where DCI corresponding to downlink data for DL retransmission or new DL transmission is located, and receive DL retransmission data.
Those skilled in the art will understand that, in the implementation, the network may configure RRC signaling so that the UE may not start the drx retransmission timer after the drx HARQ round trip time timer expires. Alternatively, the network may be configured with RRC signaling so that the UE may start the drx retransmission timer after the drx HARQ round trip time timer expires.
Therefore, by the technical scheme provided by the embodiment of the invention, more power consumption can be saved for the connected UE configured with the DRX mode based on the RTT duration characteristic of NTN communication, and the power saving advantage of DRX can be effectively exerted.
