Description

Timer processing method and device

Technical field

This application relates to the field of communication technology, and in particular to a timer processing method and device.

Background technique

In order to save the power consumption of the terminal equipment, a discontinuous reception (DRX) mechanism is introduced. The DRX mechanism means that the terminal equipment shuts down the receiver for a period of time to reduce power consumption when there is no data transmission.

In the traditional solution, the base station configures a DRX cycle for the terminal. The DRX cycle includes "on duration" and "opportunity for DRX". "on duration" is also called the activation period, and "opportunity for DRX" is also called the sleep period. . The terminal monitors the physical downlink control channel (PDCCH) during the on duration, and receives the physical downlink shared channel (PDSCH) according to the downlink control information (DCI) carried in the PDCCH to obtain The downlink transmission block (TB) or the physical uplink shared channel (PUSCH) carrying the uplink transmission block is sent according to the downlink control information carried in the PDCCH, and the terminal does not monitor the PDCCH during the sleep period.

However, in eMTC and NB-IoT communication technologies, PDCCH and TB are repeatedly sent, and each PDCCH can only call one TB. For example, when one PDCCH schedules one TB, the PDCCH needs to be repeatedly sent 256 times at most. For multiple TBs, for example, when 4 TBs are scheduled, PDCCH needs to be repeatedly sent for each TB, and a large amount of resources are used to send PDCCH, resulting in low resource utilization efficiency. To this end, a method for scheduling multiple TBs with one PDCCH is introduced. In the above example, 4 TBs need to be sent at most 4×256=1024 PDCCHs. In the method of scheduling multiple TBs with one PDCCH, one PDCCH repeatedly sends 256 times. 4 TBs can be scheduled at one time, which reduces the number of PDCCH transmissions and improves resource utilization efficiency. At present, the timers involved in the DRX mechanism are all designed based on one PDCCH for scheduling one TB, which cannot meet the above scenario of scheduling multiple TBs by one PDCCH, and may affect the continuity of service data transmission.

Summary of the invention

This application provides a timer processing method and device to improve resource utilization efficiency of TB transmission.

The first aspect of this application provides a timer processing method, including:

The terminal receives the physical downlink control channel PDCCH during the running time of the discontinuous reception DRX cycle. The PDCCH includes scheduling information. The scheduling information is used to indicate: the number of transmission blocks TB and the number of repetitions M of the TB, where L is greater than An integer of 1, and M is an integer greater than or equal to 1; the terminal determines the first duration of the DRX inactivation timer according to the L and the M; the terminal starts the DRX inactivation timer.

In an exemplary manner, the first duration is greater than the duration of the terminal receiving or sending the L TBs, or the timeout time of the DRX inactivation timer is later than the sending or receiving completion time of the L TBs.

In an exemplary manner, the method further includes: the terminal acquiring the second duration; the terminal determining the first duration of the DRX inactivation timer according to the L and the M, including: the terminal according to the second duration, The L and M determine the first duration.

In an exemplary manner, the terminal acquiring the second duration includes: the terminal receives the second duration from a base station; or, the terminal acquires the second duration locally.

In an exemplary manner, the first time length, the second time length, the M, and the L satisfy the following relationship: drx _T1 = drx _T0 + (L–i)×M; where drx _T1 is the first One duration, drx _T0 is the second duration; i is a non-negative integer less than or equal to L.

In an exemplary manner, in the L TBs, there is a gap between two adjacent TBs, and the terminal determines the first duration of the DRX inactivation timer according to the number of repetitions of the L and the TB, including : The terminal determines the first duration of the DRX inactivity timer according to the second duration, the L, the M, and the duration of the gap.

In an exemplary manner, the first time length, the second time length, the L, the M, and the time length of the gap satisfy the following relationship: drx _T1 = drx _T0 +(L–i)×M+( L–j)×G; where drx _{T1 is} the first duration of the DRX inactive timer, drx _T0 is the second duration, and G is the duration of the gap; i is a non-negative integer less than or equal to L; j Is a non-negative integer less than or equal to L.

In the embodiment of this application, after the terminal monitors the PDCCH, in order to continuously receive or send TB during the dormant period of the DRX cycle, the terminal will start or restart a DRX-inactivity timer (DRX-inactivitytimer). During the running time of the inactive timer, the terminal device monitors the PDCCH to support the continuity of TB transmission. In the traditional solution, the timing duration of the DRX inactive timer only matches the receiving or sending duration of a TB. The traditional solution can continuously monitor the PDCCH after the terminal completes a TB to achieve continuous TB transmission. If a PDCCH is scheduled For multiple TBs, when multiple TBs have not been transmitted, the DRX inactivation timer has expired. After the terminal completes the transmission of this multiple TB, it can only continue to monitor until the next active period of the DRX cycle arrives. PDCCH causes discontinuous TB transmission. In the embodiment of the present application, after receiving the PDCCH including scheduling information of L transport blocks TB within the active time of the discontinuous reception DRX cycle, the timing duration of the DRX inactive timer is adjusted by the number of repetitions of L and TB , The first duration of the adjusted DRX inactivation timer can be greater than the duration of the terminal receiving or sending L TBs. When the base station schedules multiple TBs through one PDCCH, the DRX inactivation timer of the terminal can support the terminal to receive or send After the multiple TBs are sent, the PDCCH can be continuously monitored to achieve transmission continuity. Therefore, the embodiment of the present application can support one PDCCH to schedule multiple TBs, thereby improving the resource utilization rate of TB transmission.

In an exemplary manner, the first moment is the moment or subframe when the terminal receives or transmits the last repeated block of the last TB among the L TBs.

In an exemplary manner, the timing durations of the L HARQ round trip timers are different.

In an exemplary manner, among the L HARQ round-trip timers, the duration HARQ RTT _Tt of the HARQ round-trip timer corresponding to the t-th TB satisfies the following relationship: HARQ RTT _Tt = HARQ RTT _T0 +(t-1 )×N; wherein, HARQ RTT _T0 is the pre-configured HARQ round trip timer timing duration, N is the number of repeated transmissions of the PUCCH; t is an integer greater than 1 and less than or equal to the L.

Or, the second time is later than the time when the terminal starts to receive or send the L TBs so that the DRX inactivation timer expires after the terminal sends or receives the L TBs.

In an exemplary manner, the terminal starts the DRX inactivation timer at the last repeated block of the L-1 TB among the L TBs; or, the terminal starts the DRX inactivation timer in the L TB among the L TBs. The first repeated block of the TB starts the DRX inactivation timer; or, the terminal starts the DRX inactivation timer in the last repeated block of the Lth TB in the L TBs.

Detailed ways

The embodiment of the application provides a method for processing a timer. FIG. 1 is a schematic diagram of a network architecture to which the embodiment of the application is applicable. As shown in FIG. 1, the network architecture includes a base station and at least one terminal. , The base station mentioned in the embodiment of this application may be a base transceiver station (BTS) of a global system of mobile communication (GSM) system or a code division multiple access (CDMA) system. It can be a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved base station (evolved NodeB, eNB) in a long term evolution (LTE) system , Access point (AP) or relay station, it can also be a base station (such as gNB or transmission point (TRP)) in the fifth generation mobile communication (5Generation, 5G) system, or cloud wireless Wireless controllers and wearable devices or vehicle-mounted devices in the cloud radio access network (CRAN) scenario. It is not limited here. The 5G system is also called a new wireless communication system, a new radio (NR) or a next-generation mobile communication system.

The terminal mentioned in the embodiments of this application may be user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile equipment, UE terminal, terminal, Wireless terminal, UE agent, UE device, etc. It can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a wireless communication function Handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminals in the future 5G network or terminals in the future evolved public land mobile network (PLMN), etc. Figure 2 shows a schematic diagram of the TB transmission process of the base station and the terminal in eMTC and NB-IoT. As shown in FIG. 2, in a DRX cycle, the terminal monitors the PDCCH during the onduration timer (that is, the active period). The base station will repeatedly transmit the PDCCH for k (k is a natural number) times. (For example, the PDCCH can be used to invoke m (m is a natural number) PDSCH). If the terminal monitors the PDCCH during the onduration timer operation, the terminal repeatedly transmits the PDCCH on the PDCCH. A DRX inactivity timer (DRX-inactivitytimer) is started in the last subframe. During the operation of the DRX-inactivitytimer, the terminal monitors the PDCCH.

In the embodiments of the present application, starting a timer in a subframe can be understood as starting the timer at any time within a subframe, for example, starting the timer at the beginning of the subframe, or starting the timer at the beginning of the subframe. The timer is started at the middle time of the frame, or the timer is started at the end time of the subframe, which is not limited in this application.

For downlink, after the terminal obtains the TB from the PDSCH according to the PDCCH, the base station does not immediately schedule the process corresponding to the TB. For example, after the terminal obtains the TB, the terminal needs to process the TB (for example, decode the TB), and then the terminal sends to the base station n (n is a natural number) physical uplink control channel that carries feedback information, PUCCH) or physical uplink shared channel (PUSCH), the feedback information is used to indicate whether the TB is successfully decoded. Because the terminal is processing the TB and sending feedback information during the period, the base station will not schedule the terminal for the process corresponding to the TB. Therefore, the terminal does not need to monitor the PDCCH during this period. To this end, the terminal starts a hybrid automatic retransmit request round trip timer (hybrid auto retransmit request round trip time timer, HARQ RTT timer) in the subframe of the last repeated transmission of the TB. During the operation of HARQ RTT timer, the terminal does not respond to this The process corresponding to HARQ RTT timer monitors PDCCH. If the HARQ RTT timer expires and the terminal has not successfully decoded the TB, it will start the DRX-retransmission timer (DRX-retransmissiontimer) to monitor the retransmission schedule of the TB. If the terminal does not receive the PDCCH any more until the DRX-inactivitytimer, on-duration timer, and DRX-retransmissiontimer all time out, the terminal enters the dormant state until the next onduration timer starts.

For the uplink, similarly, the uplink (UL) HARQ RTT timer and DRX-UL retransmission timer control whether the UE monitors the PDCCH.

In the usual DRX-inactivitytimer setting, the maximum value of DRX-inactivitytimer is 2560 psf, and the TB transmission duration corresponding to the maximum number of repetitions of PDSCH is 2048 psf. Where psf is the PDCCH subframe, that is, the PDCCH subframe.

As shown in Figure 3, in a scenario where one PDCCH schedules one TB, the timing duration of DRX-inactivitytimer is greater than the maximum transmission duration of one TB, so that even if the number of repetitions of PDSCH reaches the maximum, the timing duration of DRX-inactivitytimer can still guarantee the terminal After the TB is received or sent, the DRX-inactivitytimer is still running, and the terminal can continuously monitor the PDCCH, which can achieve the purpose of scheduling the next TB and ensure the continuous transmission of service data without waiting until the next onduration timer starts.

As shown in Figure 4, when multiple TBs are scheduled by one PDCCH, if the number of repeated transmissions of each TB is the maximum number of repetitions of PDSCH, the maximum transmission duration of L TBs is L×2048 psf, where L is greater than 1. In the case of DRX-inactivitytimer, the timing duration of DRX-inactivitytimer is less than the maximum transmission duration of L TBs. In this way, the following situation may occur, that is, the terminal has not completed the reception or transmission of L TBs, and the DRX-inactivitytimer has timed out. After receiving or sending a TB, if it is in the dormant period of the DRX cycle, the terminal no longer monitors the PDCCH. If the base station needs to continue to schedule the UE, it can only wait for the onduration timer of the next DRX cycle to start, resulting in discontinuous transmission of service data .

Based on this, the first embodiment of the present application, the second embodiment of the present application, and the third embodiment of the present application can ensure the continuity of transmission service data by adjusting the DRX-inactivitytimer.

In addition, in the usual HARQ RTT timer setting, every time the transmission of a TB is completed, the HARQ RTT timer is started in the last repetition block (or called repetition) of the TB. Specifically, in the process of repeated transmission of TBs, from the second repeated transmission TB to the last repeated transmission TB can be called a repeated block. For example, assuming that the number of repeated transmissions of a TB is 4, the TB transmitted for the first time can be defined as the initial block, and the TB transmitted for the second to fourth transmissions can be defined as repeated blocks.

And, for the eMTC communication scenario, as shown in FIG. 5, in frequency division duplexing (FDD), the timing duration of the HARQ RTT timer HARQ RTT timer _{T0 is} set to 7+N, where N is the PUCCH Number of repetitions; as shown in Figure 6, in time division duplexing (TDD), the timing duration of the HARQ RTT timer is set as: HARQ RTT timer _T0 = 3+k+N, where k is the repeated transmission of PDSCH The time interval between the last subframe and the first subframe in which the PUCCH is repeatedly sent, and N is the number of PUCCH repetitions.

For the NB-IoT communication scenario, as shown in Figure 7, the timing duration of the HARQ RTT timer is set as: HARQ RTT timer _T0 = k+3+N+deltaPDCCH, where k is the last subframe of PDSCH repeated transmission and PUCCH The time interval between the first subframe of repeated transmission, N is the number of PUCCH repetitions, deltaPDCCH is the time from the last subframe plus 3 subframes of the associated HARQ feedback to the first subframe of the next PDCCH timing interval.

In a scenario where one PDCCH schedules one TB, the terminal only receives or transmits one TB at a time. After the terminal completes the reception or transmission of the one TB, it starts the HARQ RTT timer. During the operation of the HARQ RTT timer, for the receiving TB, the terminal The PUCCH can be sent to the base station. If the HARQ RTT timer expires and the terminal has not successfully received the TB, the DRX-retransmission timer is started to monitor the retransmission scheduling of the TB.

In a scenario where multiple TBs are scheduled by one PDCCH, the setting of the HARQ RTT timer usually affects the UE's monitoring of the PDCCH. Specifically, when multiple TBs are scheduled by one PDCCH, there may be two PUCCH feedback modes. A PUCCH feedback method is shown in Figure 8. Each TB corresponds to a piece of feedback information. After the terminal has received all the multiple TBs, the terminal sends to the base station in sequence from the first TB to the last TB. The feedback information corresponding to the first TB to the feedback information corresponding to the last TB, as shown in FIG. 8 is the feedback information corresponding to transmission block 1, the feedback information corresponding to transmission block 2, and the feedback information L corresponding to transmission block L. Another PUCCH feedback method is shown in FIG. 9, the feedback information of multiple TBs is merged into one unified feedback information. After the terminal completes all reception of the multiple TBs, the terminal sends the unified feedback information to the base station.

In the embodiment of the present application, the foregoing feedback method is that the UE sends feedback information to the base station through PUCCH. In another feedback method, the UE may also send the feedback information to the base station through PUSCH, which is not limited in the embodiment of the present application.

According to the usual HARQ RTT timer setting, as shown in Figure 8 or Figure 9, the terminal starts the first round trip timer HARQ RTT timer1 corresponding to the first TB in the last repeated transmission subframe of the first TB. When RTT timer1 times out, if the terminal has not successfully received the first TB, it will start the first retransmission timer DRX-retransmissiontimer1 corresponding to the first TB; the terminal will start the first retransmission timer in the last retransmission subframe of the second TB. The second round-trip timer HARQ RTT timer2 corresponding to the two TBs. When HARQ RTT timer2 expires, if the terminal does not successfully receive the second TB, the second retransmission timer DRX-retransmissiontimer2 is started, and so on, until the end One terabyte. At a time, the terminal can only receive or transmit one TB. Therefore, when the terminal receives or transmits the second TB, the base station generally does not schedule the terminal to retransmit the first TB. According to the above settings, it may be As a result, when the terminal receives or transmits the second TB, the DRX-retransmission timer1 is turned on, so that the UE performs unnecessary PDCCH monitoring, which will cause additional power consumption.

Based on the above situation, the fourth embodiment of the application and the fifth embodiment of the application adjust the HARQ RTT timer mechanism to reduce the power consumption of the terminal.

Furthermore, in single-cell point-to-multipoint (SC-PTM) multi-TB transmission, the maximum value of the SC-PTM service scheduling cycle (SCPTM-SchedulingCycle) is 8192ms, that is, NB -The IOT terminal starts an onduration timer every 8192ms to monitor the narrowband physical downlink control channel (NPDCCH). The maximum number of PDSCH repetitions is 2048. In SC-PTM, the maximum number of TBs scheduled by an NPDCCH is 8, that is, the longest PDSCH scheduled by an NPDCCH is at least 2048×8=16384ms, which is greater than 8192ms. Therefore, in an NPDCCH scheduling In the case of multiple TBs, the terminal may need to start the onduration timer to monitor the NPDCCH before receiving the multiple TBs. For the NB-IoT terminal, if the onduration timer is activated, the terminal will monitor the NPDCCH and no longer receive the PDSCH. The terminal fails to receive multiple TBs.

Based on the foregoing situation, the sixth embodiment of the present application and the seventh embodiment of the present application adjust the onduration timer to avoid the failure of the multi-TB transmission service caused by the activation of the onduration timer.

It should be noted that the PDCCH mentioned in the embodiment of the application may be a machine type communication physical downlink control channel (machine type communication physical downlink control channel) MPDCCH or NPDCCH.

In the embodiment of this application, a TB can also be understood as a PDSCH transmission (a PDSCH transmission/reception), or a PUSCH transmission a PUSCH transmission/reception, or an uplink transmission (a UL transmission/reception), or a downlink transmission ( a DL transmission/reception). For example, the first TB can be understood as the first PDSCH transmission (first PDSCH transmission/reception), or the first PUSCH transmission (first PUSCH transmission/reception), or the first uplink transmission (first UL transmission/reception), Or the first downlink transmission (first DL transmission/reception). This concept is different from the last repeated transmission of a TB. The last repeated transmission of a TB refers to a TB that needs to be repeated multiple times, and the last repeated transmission of a TB refers to the last of the multiple times. For example, in the L TBs (transmission block 1, transmission block 2 to transmission block L) shown in FIG. 8 or FIG. 9, any one of transmission block 1, transmission block 2 to transmission block L can be called a TB. For example, in Figure 8 or Figure 9, the number of repetitions for each TB is 4, then for transmission block 1, the transmission block 1 performs four repeated transmissions, and the last repeated transmission of transmission block 1 is the fourth transmission. It can be understood that if the number of repetitions of each TB is n times, the last repetitive transmission of the TB is the nth transmission.

The first embodiment of the present application provides a timer processing method to ensure the continuity of transmission services. FIG. 10 is a schematic flowchart of a timer processing method provided in Embodiment 1 of this application. As shown in FIG. 10, the method provided in this embodiment of the present application includes the following steps:

Step S101: The terminal receives the physical downlink control channel PDCCH within the running time of the discontinuous reception DRX cycle, the PDCCH includes scheduling information, and the scheduling information is used to indicate: the number L of transmission blocks TB and the number of repetitions M of the TB, where L is an integer greater than 1, and M is an integer greater than or equal to 1.

In the embodiments of this application, the PDCCH is used to carry the downlink control information (DCI) sent by the base station to the terminal, that is, scheduling information. The DCI can indicate the number of TBs L and the repetition of each TB of the L TBs frequency. The specific value of L and the specific number of repetitions of TB can be determined according to actual application scenarios, which are not specifically limited in the embodiment of the present application.

In a possible implementation manner, the active time of the discontinuous reception DRX cycle may be: the onduration timer of the DRX cycle or the running time of DRX-inactivitytimer or DRX-retransmissiontimer or DRX-ULRetransmissionTimer, During the running time of the DRX cycle, the terminal can monitor the PDCCH and receive the PDCCH.

Step S102: The terminal determines the first duration of the DRX inactivation timer according to the L and the M.

In the embodiment of the present application, the duration for the terminal to receive or send the L TBs can be determined according to the specific values of the repetition times of L and TB. In a possible implementation manner, the first duration of DRX-inactivitytimer can be adjusted to be greater than The terminal receives or sends L TB duration.

It can be understood that the specific value of the first duration of the DRX inactive timer and the specific manner for determining the first duration of the DRX inactive timer can be determined according to actual application scenarios, which are not specifically limited in the embodiment of the present application.

Step S103: The terminal starts the DRX inactivation timer.

In a possible implementation manner, the terminal may start the DRX inactivation timer in the last subframe of repeated PDCCH transmission. The terminal may also start the DRX inactive timer at other times according to actual needs, and the embodiment of the present application does not specifically limit the specific time when the DRX inactive timer is started.

For example, as shown in FIG. 11, the first duration of DRX-inactivitytimer is greater than the duration of the terminal receiving or sending L TBs. Therefore, after the terminal completes receiving or sending L TBs, the terminal can continue based on the DRX-inactivitytimer Monitor the PDCCH, so that you can continue to receive the next PDCCH scheduling, and achieve the continuity of transmission service data.

Optionally, the embodiment of the present application further includes: the terminal obtains the second duration.

In a possible implementation manner, the second duration is sent by the base station to the terminal through DCI, and the terminal may receive the second duration from the base station.

In another possible implementation manner, the second duration is stipulated by the protocol, and the terminal can obtain the second duration locally.

It can be understood that the second duration may be a constant identifying the duration of time, which is not specifically limited in the embodiment of the present invention.

A possible implementation manner of step S102 is: the terminal determines the first duration according to the second duration, L and M.

In a specific application, the base station may send the second duration to the terminal through radio resource control (RRC) signaling. It can be understood that the second duration may be the duration of the DRX inactive timer configured on the network side.

In a possible implementation manner, the second duration can be used in the scenario of PDCCH scheduling 1 TB, that is, when the DCI in the PDCCH indicates to schedule 1 TB, the terminal starts the DRX inactive timer for the second duration. duration. The specific value of the second duration may be determined according to actual application scenarios, which is not specifically limited in the embodiment of the present application.

In a possible implementation manner, when the DCI in the PDCCH indicates to schedule L TBs, the terminal starts the DRX inactive timer for the first duration.

In the embodiment of the present application, the first duration is determined on the basis of the second duration and further based on the number of repetitions of L and TB.

Optionally, as a specific implementation manner of the embodiment of the present application, the first duration drx _T1 , the second duration drx _T0, and L satisfy the following relationship: drx _T1 = drx _T0 + (L-1)×M. Specifically, in a possible implementation manner, when the DCI in the PDCCH indicates to schedule L TBs, the terminal starts the first duration of drx _T0 + (L-1)×M.

In a possible implementation manner, the first duration drx _T1 , the second duration drx _T0, and L satisfy the following relationship: drx _T1 = drx _T0 + (L-i)×M, where i is less than or equal to L The non-negative integer. Specifically, in a possible implementation manner, when the DCI in the PDCCH indicates to schedule L TBs, the terminal starts the first duration of drx _T0 + (L-i)×M.

In the embodiment of this application, the first duration can be flexibly set according to the number L of TBs and the number of repetitions M of TBs, so that the first duration can match the actual transmission conditions of the L TBs, and ensure the continuity of transmission service data. On this basis, the power consumption of additional monitoring of the PDCCH caused by the excessively long first duration can also be reduced.

Optionally, if there is a gap between two adjacent TBs in the L TBs scheduled by one PDCCH, the possible implementation of step S102 includes: the terminal according to the second duration received from the base station, L, The number of repetitions of TB and the time length of the gap determine the first time length.

In the embodiment of the present application, considering that there may be gaps in the actual L TBs, when determining the first duration, the length of the gap is also taken into consideration. It can be understood that the time length of the gap can be determined according to actual application scenarios, and the embodiment of the present application does not specifically limit it.

Specifically, in a possible implementation manner, when the DCI in the PDCCH indicates that L TBs are scheduled, and there is a gap between the L TBs, the first duration that the terminal starts is based on the second duration, the repetition of L and TB The number of times and the length of the gap are determined.

For example, as shown in Figure 12, there is a gap between each TB, and the first duration of DRX-inactivitytimer is greater than the duration of the terminal receiving or sending L TBs with gaps. Therefore, the terminal completes the L TBs with gaps. After receiving or sending, based on the DRX-inactivitytimer, the terminal can continue to monitor the PDCCH, so that it can continue to receive the next PDCCH scheduling to achieve the continuity of transmission service data.

Optionally, as a specific implementation of the embodiment of the present application, if the DCI in the PDCCH indicates that there is a gap between two adjacent TBs among the scheduled L TBs, the first duration drx _T1 and the second duration The relationship between drx _T0 , L and the time length G of the gap satisfies the following relationship: drx _T1 = drx _T0 +(L-1)×M+(L-1)×G; where M is the number of repetitions of TB, and G is the gap The length of time. Specifically, in a possible implementation manner, when the DCI in the PDCCH indicates that L TBs are scheduled and there is a gap between the L TBs, the first duration of the terminal startup is drx _T0 +(L-1)×M+( L–1)×G.

Optionally, as a specific implementation of the embodiment of the present application, if the DCI in the PDCCH indicates that there is a gap between two adjacent TBs among the scheduled L TBs, the first duration drx _T1 and the second duration The relationship between drx _T0 , L and the time length G of the gap satisfies the following relationship: drx _T1 = drx _T0 +(L–i)×M+(L–j)×G; where M is the number of repetitions of TB and G is the gap The length of time, i and j are non-negative integers less than or equal to L. Specifically, in a possible implementation manner, when the DCI in the PDCCH indicates that L TBs are scheduled and there is a gap between the L TBs, the first duration of the terminal startup is drx _T0 + (L-i) × M + ( L–j)×G.

In the embodiment of the present application, the first duration can be flexibly set according to the number L of TBs, the number of repetitions M of TBs, and the time length G of the gap, so that the first duration can match the actual transmission situation of L TBs with gaps. , On the basis of ensuring the continuity of the transmission service data, it can also reduce the power consumption caused by the extra monitoring of the PDCCH caused by the excessively long first duration.

Optionally, in an implementation manner of the embodiment of the present application, in the case that there is a gap between two adjacent TBs in the L TBs, the terminal does not monitor the PDCCH in the gap between the adjacent TBs.

In the embodiment of this application, considering that the duration of the gap is generally short, the base station usually does not send the PDCCH during the gap. If the terminal continues to monitor the PDCCH during the gap, additional power consumption will be caused. Therefore, in this embodiment of the application, , Do not monitor PDCCH in the gap between adjacent TBs, which can reduce the power consumption of the terminal.

Optionally, as a specific implementation of the embodiment of the present application, the base station may indicate in the DCI whether there is a gap between L TBs, and the terminal may receive gap indication information, which is used to indicate L transmission blocks There is a gap in.

In summary, in the embodiment of the present application, by adjusting the duration of DRX-inactivitytimer, after the terminal completes the reception or transmission of L TBs, based on the DRX-inactivitytimer, the terminal can continue to monitor the PDCCH, so that it can continue to receive the next time PDCCH scheduling realizes the continuity of transmission service data.

The second embodiment of the present application provides another timer processing method to ensure the continuity of transmission service data. FIG. 13 is a schematic flowchart of a timer processing method provided in Embodiment 2 of this application. As shown in FIG. 13, the method provided in this embodiment of the present application includes the following steps:

Step S201: The terminal receives the physical downlink control channel PDCCH within the running time of the discontinuous reception DRX cycle, the PDCCH includes scheduling information, and the scheduling information is used to indicate: the number L of transmission blocks TB and the number of repetitions M of the TB, where L is an integer greater than 1, and M is an integer greater than or equal to 1.

Step S202: The terminal starts the DRX inactive timer at the second moment according to the L and the M.

In the embodiment of this application, the terminal may receive L TBs in PDSCH or transmit L TB blocks in PUSCH according to the instructions of the scheduling information. Considering that when the terminal receives or transmits the current L TBs, it usually does not follow the PDCCH For other TB transmissions, the DRX-inactivitytimer is delayed in the embodiment of the application. Specifically, the timer is started at the second time. To ensure the continuity of service data transmission, DRX can be started at the second time. After the inactive timer, the sum of the time between the time when the terminal starts receiving or sending L TBs and the second time and the timing duration of the DRX inactive timer is greater than the length of receiving or sending L TBs, or the second time It is later than the time when the terminal starts to receive or send the L TBs so that the DRX inactivation timer expires after the terminal finishes sending or receiving the L TBs.

It should be noted that the time described in the embodiment of the present application is not limited to a certain time point, and may also be a small time range, for example, the time may be a subframe.

For example, as shown in FIG. 14, it shows the method of starting DRX-inactivitytimer at the second moment in the embodiment of the present application. It can be understood that the second moment may start from the terminal receiving or sending the first TB to the terminal. Any time between the end of receiving or sending the last TB.

Optionally, in a possible implementation manner of the embodiment of the present application, the way for the terminal to enable DRX-inactivitytimer may be: the terminal starts at the last repeat block (or repeat subframe) of the L-qth TB among the L TBs DRX inactivation timer, where q is a non-negative integer less than or equal to L; or, the terminal starts the DRX inactivation timer at the first repeated block of the L-qth TB among the L TBs; where q is less than Or a non-negative integer equal to L. For example, the terminal starts the DRX inactivation timer in the last repeated block of the Lth TB in the L TBs.

It is understandable that in a possible implementation manner of the embodiment of this application, because the start time of DRX-inactivitytimer may be the last repeat block of the L-1th TB, or it may be the first repeat block of the Lth TB Block, or it can be the first repeated block of the Lth TB. The three opening moments are all near the moment of receiving or sending the last TB, and usually the timing of DRX-inactivitytimer is longer than the receiving or sending of one TB Therefore, enabling the DRX-inactivitytimer through these three methods can ensure that the DRX-inactivitytimer has not timed out at the end of the L-th TB transmission, thereby ensuring the continuity of the transmission service data.

In a possible implementation, the start time of the DRX-inactivitytimer may be p+Offset, where p may be the first repeated subframe of the Lqth TB, or p may be the last of the Lqth TB Repeat subframe; Offset is the offset, and its value is an integer (including positive integer, negative integer and zero).

Optionally, considering that there may be gaps in the actual L TBs, when determining the start time of DRX-inactivitytimer, the length of the gap can be considered as a factor, that is, the terminal needs to start receiving or sending L TBs The sum of the duration between time and the second time, the timing duration of the DRX inactive timer, and the duration of (L-1) gaps is greater than the duration of receiving or sending L TBs and the duration of (L-1) intervals The sum.

Optionally, there may be gaps in the actual L TBs. Considering that the duration of the gap is usually short, the base station usually does not send the PDCCH during the gap. If the terminal continues to monitor the PDCCH during the gap, it will cause extra work. Therefore, in the embodiment of the present application, the PDCCH is not monitored in the gap between adjacent TBs, which can reduce the power consumption of the terminal.

In summary, in the embodiments of the present application, by delaying the on time of DRX-inactivitytimer, after the terminal completes receiving or sending L TBs, based on the DRX-inactivitytimer, the terminal can continue to monitor the PDCCH, so that it can continue to receive One PDCCH scheduling realizes the continuity of transmission service data.

The third embodiment of the present application provides another timer processing method to ensure the continuity of transmission services. FIG. 15 is a schematic flowchart of a timer processing method provided in Embodiment 3 of this application. As shown in FIG. 15, the method provided in this embodiment of the present application includes the following steps:

Step S301: The terminal receives the physical downlink control channel PDCCH within the running time of the discontinuous reception DRX cycle, the PDCCH includes scheduling information, and the scheduling information is used to indicate: the number L of transmission blocks TB and the number of repetitions M of the TB, where L is an integer greater than 1, and M is an integer greater than or equal to 1.

Step S302: The terminal receives or sends L TBs according to the L and the M, and when the DRX inactivation timer expires, if the terminal has not completed receiving or sending L transport blocks, the terminal restarts the DRX inactivation timer.

In the embodiment of this application, the judgment logic is set in the terminal. When the DRX inactivation timer expires, if the terminal does not complete the reception or transmission of L transport blocks, and the terminal restarts the DRX inactivation timer, it can ensure that the terminal completes L After the TB is received or sent, based on the DRX-inactivitytimer, the terminal can continuously monitor the PDCCH, so that it can continue to receive the next PDCCH scheduling to achieve the continuity of transmission service data.

As an example, as shown in FIG. 16, a schematic diagram of restarting DRX-inactivitytimer in an embodiment of the present application is shown. It can be understood that in this embodiment of the present application, the DRX-inactivitytimer start time may be the DRX-inactivitytimer start time in the prior art. That is, if the terminal receives a PDCCH, and the PDCCH indicates a new transmission, the terminal starts DRX-inactivitytimer. The turn-on time of the DRX-inactivitytimer may also be other turn-on time determined according to actual application scenarios, which is not specifically limited in the embodiment of the present application. If the PDCCH indicates the transmission of L TBs, when the DRX-inactivitytimer times out and the L TBs have not completed transmission, the terminal restarts the DRX-inactivitytimer.

Optionally, considering that the duration of the gap is usually short, the base station usually does not send the PDCCH during the gap. If the terminal continues to monitor the PDCCH during the gap, additional power consumption will be caused. Therefore, in this embodiment of the application, if There are gaps between adjacent TBs, and the PDCCH is not monitored in the gaps between adjacent TBs, which can reduce the power consumption of the terminal.

To sum up, in this embodiment of the application, by setting the judgment logic in the terminal, when the DRX inactivation timer expires, if the terminal has not completed receiving or sending L transport blocks, the terminal restarts the DRX inactivation timer, then It can be ensured that after the terminal completes the reception or transmission of L TBs, based on the DRX-inactivitytimer, the terminal can continuously monitor the PDCCH, so that it can continue to receive the next PDCCH scheduling, and achieve the continuity of transmission service data.

The fourth embodiment of the present application provides another timer processing method to reduce power consumption during data transmission. FIG. 17 is a schematic flowchart of a timer processing method provided in Embodiment 4 of this application. As shown in FIG. 17, the method provided in this embodiment of the present application includes the following steps:

Step S401: The terminal receives the physical downlink control channel PDCCH within the running time of the discontinuous reception DRX cycle, the PDCCH includes scheduling information, and the scheduling information is used to indicate: the number L of transmission blocks TB and the number of repetitions M of the TB, where L is an integer greater than 1, and M is an integer greater than or equal to 1.

Step S402: The terminal starts L hybrid automatic retransmission HARQ round trip timers corresponding to L TBs at the first moment according to L and M.

In a possible implementation manner, the duration of the HARQ round trip timer corresponding to each TB is greater than the duration of the terminal sending the feedback information corresponding to the TB to the base station. Optionally, the feedback information may be carried on the physical uplink control channel PUCCH.

In a possible implementation manner, the timeout moment of the HARQ round trip timer corresponding to each TB is the end moment when the UE sends the feedback information corresponding to the TB to the base station.

Specifically, in a possible implementation manner, the terminal starts L hybrid automatic retransmission HARQ round-trip timers at the first moment. It may be that the terminal starts at the first moment for each TB or the process corresponding to each TB. A HARQ round trip timer.

Specifically, in a possible implementation manner, if the DCI in the PDCCH schedules L TBs, the terminal starts L HARQ round trip timers at the first moment.

In the embodiment of this application, the HARQ RTT timers corresponding to L TBs are uniformly started at the first moment, so that when multiple TBs are scheduled by one PDCCH, the HARQ round trip timer is prevented from being triggered by the TB received in advance, and the start is triggered. Retransmission timer, and the base station will not schedule the retransmission of the TB before receiving the feedback information of the TB. If the retransmission timer is triggered to start, the UE may monitor the PDCCH and cause the UE power consumption to increase. In order to solve this problem, in the embodiment of the present application, the HARQ round trip timer corresponding to each TB is delayed to start, which further delays the start of the retransmission timer and reduces unnecessary PDCCH monitoring by the terminal. In a possible implementation manner, the HARQ round trip timer corresponding to each TB is longer than the duration of the terminal sending feedback information to the base station, so for each TB, the HARQ RTT timer controls the terminal during the period when the terminal sends feedback information to the base station. The PDCCH is not monitored, so that the power consumption of the terminal can be reduced.

In the embodiment of the present application, the HARQ round trip timer corresponding to a TB can also be understood as a timer corresponding to a HARQ process. For example, the HARQ round trip timer corresponding to a TB can also be understood as a HARQ round trip timer corresponding to a HARQ process.

Optionally, in a specific implementation manner of the embodiment of the present application, the first moment may be the moment when the terminal receives or transmits the last repeated block of the last TB among the L TBs or the last repeated subframe.

In the embodiment of the present application, after the terminal receives or sends the last repeated block of the last TB in the L TBs, the terminal will uniformly send feedback information to the base station, so the terminal receives or sends the last TB of the L TBs The HARQ round trip timer is started at the time of the last repeated block, so that the terminal does not monitor the PDCCH when sending feedback information to the base station, thereby reducing the power consumption of the terminal.

Optionally, in a specific implementation manner of the embodiment of the present application, the timing durations of the L HARQ round-trip timers are different.

In the embodiment of this application, considering that when the terminal sends feedback information to the base station, the terminal sends the feedback information corresponding to the first TB to the feedback information corresponding to the last TB to the base station in the order from the first TB to the last TB. information. Therefore, for L TBs, the time from the end of receiving or sending L TBs to when the terminal completes the sending of feedback information corresponding to L TBs is different. Therefore, according to the sending duration of feedback information corresponding to L TBs, To set the duration of L HARQ round trip timers to adapt to the sending of feedback information corresponding to L TBs.

Optionally, in a specific implementation manner of the embodiment of the present application, among the L HARQ round-trip timers, the HARQ round-trip timer duration HARQ RTT _Tt corresponding to the t-th TB satisfies the following relationship:

HARQ RTT _Tt = HARQ RTT _T0 + (t-1)×N, where HARQ RTT _T0 is the first duration, the first duration is pre-configured or received from the base station, and N is the transmission duration of the feedback information, or N Is the number of repeated transmissions of PUCCH; t is an integer greater than 1 and less than or equal to L.

It can be understood that for different communication scenarios, the pre-configured value of HARQ RTT _T0 may be different, and the specific pre-configured value of HARQ RTT _T0 is not limited in the embodiment of the present application.

As an example, as shown in FIG. 18, a schematic diagram of setting the HARQ RTT timer is shown. Taking the FDD communication scenario in eMTC as an example, HARQ RTT timer _T0 =7+N.

For the first TB, HARQ RTT _T1 = 7+N.

For the second TB, HARQ RTT _T2 = 7+N+N.

For the third TB, HARQ RTT _T3 = 7+N+N+N.

For the p-th TB, HARQ RTT _Tp =7+p×N; p is less than or equal to a positive integer of L.

By analogy, for the Lth TB, HARQ RTT _TL = 7+N+(L-1)×N.

In this embodiment of the application, the HARQ RTT timer can be flexibly set according to the number of TBs L and the number of repetitions N of PUCCH, so that the HARQ RTT timer can match the length of the feedback information corresponding to the L TBs. In turn, the start time of the DRX-retransmision timer corresponding to each TB can be made just after the feedback information of the TB is sent, avoiding starting the DRX-retransmision timer in advance, thereby reducing the power consumption of the terminal.

Optionally, in a specific implementation of the embodiment of the present application, in the L feedback information transmissions corresponding to the L TBs, when there is a gap between two adjacent feedback information transmissions, the L HARQ The HARQ round trip timer duration HARQ RTT _Tt corresponding to the t th TB in the round trip timer satisfies the following relationship:

HARQ RTT _Tt = HARQ RTT _T0 +(t-1)×N+(t-1)×G

Among them, HARQ RTT _T0 is the timing duration of the pre-configured HARQ round trip timer, N is the number of repeated PUCCH transmissions; G is the time length of the gap between two adjacent feedback information transmissions; t is greater than 1 and less than or equal to L The integer.

In a possible implementation manner, if the PDCCH schedules the transmission of L TBs, and the feedback information of the L TBs is sent independently, and there is a gap between the feedback information transmissions corresponding to the L TBs, the terminal is in the L TB In the last repeated transmission, the HARQ RTT timer is started for each TB or for each process, and the duration of the t-th HARQ RTT timer is HARQ RTT _T0 +(t-1)×N+(t-1)×G.

In a possible implementation manner, if the PDCCH schedules the transmission of L TBs, the terminal starts the HARQ RTT timer for the process corresponding to the TB during the last repeated transmission of the last TB; this implementation manner may also include the HARQ RTT The timer runs until the feedback information corresponding to the last TB is sent.

In the embodiment of the present application, considering that there may be gaps in the actual L TBs, when determining the HARQ RTT _Tt , the length of the gap is also taken into consideration. It can be understood that the time length of the gap can be determined according to actual application scenarios, and the embodiment of the present application does not specifically limit it.

Optionally, considering that the duration of the gap is usually short, the base station usually does not send the PDCCH during the gap. If the terminal continues to monitor the PDCCH during the gap, additional power consumption will be caused. Therefore, in the embodiment of the present application, The PDCCH is not monitored in the gap between adjacent TBs, which can reduce the power consumption of the terminal.

Optionally, in a possible implementation manner of the embodiment of the present application, the timing duration of the L HARQ round-trip timers is the same. The duration of each HARQ round trip timer can be 7+L×N. In a possible implementation manner, if the PDCCH indicates to schedule L TBs, if the feedback information of the L TBs are sent independently (that is, not multiplexed together), the last repeat transmission of the last TB among the L TBs The subframe starts HARQ RTT timer for each process corresponding to L TBs, and the duration is 7+L×N.

In a possible implementation manner, if the PDCCH indicates to schedule L TBs, and if the feedback information of the L TBs are multiplexed together, the last repeated transmission subframe of the last TB in the L TBs corresponds to the L TBs Each process starts HARQ RTT timer, and the duration is 7+N.

In the embodiment of this application, the indication information indicating the scheduling of L TBs and/or the indication information indicating whether the feedback information is multiplexed together and/or the indication information indicating whether there is a gap between the TBs and/or the indication information indicating whether there is a gap between the feedback information The indication information that there is a gap may be carried in the PDCCH, or may also be carried in the RRC signaling.

In summary, in the embodiment of the present application, after the terminal receives or sends the last repeated block of the last TB among the L TBs, the terminal will uniformly send feedback information to the base station. Therefore, in the terminal receiving or sending the L TBs The HARQ RTT timer is started at the time of the last repeat block of the last TB, which enables the terminal to not monitor the PDCCH when sending feedback information to the base station, and delays the start of the retransmission timer, thereby reducing the power consumption of the terminal.

Embodiment 5 of the present application provides another timer processing method to reduce power consumption during data transmission.
