Background technique

At present, in wireless communication systems, such as long-term evolution (LTE) communication systems and the 5th generation (5G) communication systems, connected-discontinuous reception (C- DRX) mechanism, under this mechanism, when the terminal device is in the radio resource control (radio resource control, RRC) connection state, it periodically enters the sleep state (or called the sleep mode or sleep period, etc.), and does not listen in the sleep state Physical downlink control channel (PDCCH), when the PDCCH needs to be monitored, the terminal device wakes up from the sleep state and enters the active state (or called the active period or active mode, etc.), thereby saving power .

In the existing C-DRX mechanism, the network device configures a fixed discontinuous reception cycle (DRX cycle) for the terminal device in advance, and the terminal device monitors the PDCCH according to the fixed discontinuous reception cycle for a period of time. Since the service status of the terminal equipment changes in real time, the fixed discontinuous reception period pre-configured by the network equipment may not be suitable for the real-time service status of the terminal equipment. Therefore, how to configure discontinuous reception to adapt to the real-time changing service status of terminal equipment is a problem worthy of study.

When the network device determines that the terminal device needs to receive signals during the activation period of M continuous discontinuous reception, it reduces the period of discontinuous reception by the first step. And/or, the first discontinuous reception configuration parameter includes the adjustment step size and N, and when the adjustment step includes the second step size, the terminal device determines that the signal is not required to be received during the activation period of N consecutive discontinuous receptions, and will not The period of continuous reception is increased by a second step, and the network device determines that the terminal device does not need to receive a signal during the activation period of N consecutive discontinuous receptions, and the period of discontinuous reception is increased by the second step.

Among them, the adjustment step is used to adjust the period of discontinuous reception, M and N are both positive integers greater than or equal to 2, M is the number of consecutive times the terminal device needs to receive a signal in each active period of discontinuous reception, and N is the terminal The device does not need to receive the signal consecutive times in each activation period of discontinuous reception.

Through the above method, the network device only needs to configure the discontinuous reception configuration parameters for the terminal device once to realize the adaptive adjustment of the period of discontinuous reception. There is no need for additional signaling interaction between the terminal device and the network device, which can save information. In addition, using this method to adjust the period of discontinuous reception is not limited to adjusting the period of discontinuous reception between DRX short period and/or DRX long period. This method can increase DRX short period or DRX long period Or reduce the adjustment step length, and the adjustment step length in this application is not limited, so the flexibility of adjusting the period of discontinuous reception using the method of this application is higher.

The radio frequency device can be implemented remotely from the baseband device or integrated into the baseband device. , Or part of the remote part is integrated in the baseband device. For example, in an LTE communication system, a base station includes a baseband device and a radio frequency device. The radio frequency device can be arranged remotely from the baseband device, for example, a remote radio unit (RRU) is arranged remotely from the BBU.

The communication between the base station and the terminal follows a certain protocol layer structure. For example, the control plane protocol layer structure may include the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, and the media interface. Access control (media access control, MAC) layer and physical layer and other protocol layer functions. The user plane protocol layer structure can include the functions of the PDCP layer, the RLC layer, the MAC layer, and the physical layer; in one implementation, the PDCP layer can also include a service data adaptation protocol (SDAP) layer .

The base station can implement the functions of the RRC, PDCP, RLC, and MAC protocol layers by one node; or multiple nodes can implement the functions of these protocol layers; for example, in an evolution structure, the base station can include a centralized unit (centralized unit). , CU) and distributed unit (distributed unit, DU), multiple DUs can be centrally controlled by one CU. CU and DU can be divided according to the protocol layer of the wireless network. For example, the functions of the PDCP layer and above protocol layers are set in the CU, and the protocol layers below the PDCP, such as the RLC layer and MAC layer, are set in the DU.

This type of protocol layer division is just an example, it can also be divided in other protocol layers, for example, in the RLC layer, the functions of the RLC layer and above protocol layers are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; Or, in a certain protocol layer, for example, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are set in the DU. In addition, it can also be divided in other ways, for example, by time delay, and functions that need to meet the delay requirement for processing time are set in the DU, and functions that do not need to meet the delay requirement are set in the CU.

In addition, the radio frequency device can be remote, not placed in the DU, can also be integrated in the DU, or part of the remote part is integrated in the DU, and there is no restriction here.

Optionally, the control plane (CP) and the user plane (UP) of the CU can also be separated and realized by dividing them into different entities, namely the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity) ).

In the above network architecture, the signaling generated by the CU can be sent to the terminal through the DU, or the signaling generated by the terminal can be sent to the CU through the DU. The DU may directly pass the protocol layer encapsulation without analyzing the signaling and transparently transmit it to the terminal or CU. If the following embodiments involve the transmission of such signaling between the DU and the terminal, at this time, the sending or receiving of the signaling by the DU includes this scenario. For example, RRC or PDCP layer signaling will eventually be processed as PHY layer signaling and sent to the terminal, or converted from received PHY layer signaling. Under this architecture, the RRC or PDCP layer signaling can also be considered to be sent by the DU, or sent by the DU and radio frequency.

In the above embodiment, the CU is divided into network equipment on the radio access network (RAN) side. In addition, the CU may also be divided into network equipment on the core network (CN) side, which is not limited here.

The devices in the following embodiments of the present application may be located in terminals or network devices according to the functions they implement. When the above CU-DU structure is adopted, the network device may be a CU node, or a DU node, or a base station including a CU node and a DU node.

3) DRX, under the DRX mechanism, the terminal device will stop monitoring the PDCCH during the sleep period. According to the working state of DRX, DRX can be divided into two types: idle state (IDLE) DRX and connected state (CONNECTED) C-DRX.

IDLE DRX refers to the discontinuous reception when the terminal device is in the idle state. When the terminal device is in the idle state, there is no RRC connection and terminal device's exclusive resources. Therefore, the terminal device under IDLE DRX mainly monitors paging messages. By defining the period of paging messages, the purpose of discontinuous reception can be achieved. When the terminal device monitors user data, it leaves the idle state, for example, first enters the connected state from the idle state.

C-DRX refers to DRX when the terminal device is in the RRC connected state. In the C-DRX mode, the terminal device can be in a variety of states, as shown in Figure 1, which is a possible C-DRX mode process. In the process shown in Figure 1, the terminal device can be in the active period (on duration) or sleep period, where the sleep period can include light sleep (short sleep) and deep sleep (long sleep). During the active period, the terminal device will monitor the PDCCH, and during the sleep period, the terminal device will stop monitoring the PDCCH to reduce terminal device detection. PDCCH energy consumption. Among them, the sleep period can also be referred to as a sleep state or an OFF state.

4) The cycle of discontinuous reception (DRX cycle) may include a long DRX cycle (long DRX cycle) and a short DRX cycle (short DRX cycle), where the long DRX cycle is an integer multiple of the short DRX cycle. Regardless of whether it is a long DRX cycle or a short DRX cycle, one DRX cycle is equal to the sum of the active period (which can be called wake-up time) and the sleep period (which can be called sleep time), as shown in Figure 1. In each DRX cycle, the terminal device will wake up to monitor the PDCCH during the active period and stop monitoring the PDCCH during the sleep period. Network equipment can configure DRX short cycle and DRX long cycle for terminal equipment. When DRX short cycle ends, terminal equipment can enter DRX long cycle. Network equipment can also configure DRX long cycle for terminal equipment without configuring DRX short cycle. DRX The configuration of the long cycle and the DRX short cycle is determined according to actual usage requirements. In this application, the long DRX cycle can also be described as a long DRX cycle, and the short DRX cycle can also be described as a short DRX cycle, and the name of the DRX cycle is not limited in this application.

5) Signal. The signal in the embodiment of the present application may include data and/or control signaling. Correspondingly, the need to receive a signal can be understood as the need to receive data and/or control signaling; the need to receive a signal can be understood as the need to receive data and/or control signaling.

6) Time unit is a time unit. For example, it can include one or more consecutive transmission time intervals (TTI), time slots, time domain symbols (symbols), subframes, and orthogonal frequency division multiplexing ((orthogonal frequency division multiplexing, OFDM). ) Symbol, etc. The slot can be a full slot or a mini-slot (or non-slot), and the mini-slot contains less than 14 orthogonal frequency division multiplexing ( Orthogonal frequency division multiplexing (OFDM) symbols, a mini-slot can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13 OFDM symbols.

7) Introduction to millimeter wave beam management

5G NR mainly uses antenna arrays to beam-forming signals to achieve precise narrow beams to provide services to user data, which can achieve longer coverage distances and reduce interference.

Beam management is the basic feature of the millimeter wave protocol. In TR38.802, the key process of beam management is defined: the L1/L2 process of acquiring and maintaining the uplink and downlink data transmission and reception beam sets, including beam determination, beam measurement, and beam scanning And beam reporting.

(1) Beam determination refers to the process in which TRP or UE selects a suitable transmitting and receiving beam. The requirement on the UE side is that the UE performs an alignment process after receiving the millimeter wave beam on the network device side, including downlink beam and uplink beam selection, and finally selects the optimal beam. The UE needs to meet beam reciprocity.

(2) Beam measurement refers to the shaped signal received by the UE from the network equipment side. The shaped signal includes beam information. The requirements of the UE side are: the beamforming signal of the network can be measured correctly, and the beam measurement can be reported correctly Signals can perform other actions of beam management based on the measurement results.

(3) Beam scanning means that within a space area, the beam is sent and/or received in a predetermined manner within a certain time interval. The requirement on the UE side is that the UE can scan the beam within a certain period of time and process the scan result correctly.

(4) Beam reporting means that the UE reports shaped signal information based on beam measurement. The requirement of the UE side is that the UE can report measurement information according to the requirements of the network side in different states, and take corresponding actions after the network equipment side responds.

8) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. In view of this, "multiple" may also be understood as "at least two" in the embodiments of the present application. "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one refers to including one, two or more, and does not limit which ones are included. For example, including at least one of A, B, and C, then the included can be A, B, C, A and B, A and C, B and C, or A and B and C. "And/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone. In addition, the character "/", unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

Unless otherwise stated, the ordinal numbers such as “first” and “second” mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority, or importance of multiple objects.

In the process of wireless communication, for example, in the process of 5G communication (sub-6GHz and millimeter wave), the path loss is very high, and the power consumption of the terminal device is large. In order to reduce the power consumption of the terminal device and increase the battery life, the terminal will be frequently used The device enters the DRX state. Especially for the following scenarios:

(1) Services that are not sensitive to time delay and have data to be received and sent not most of the time, such as browsing the web, sending and receiving emails (email), or using file transfer protocols (FTP);

(2) Periodic continuous small data packet service, data transmission is relatively regular, such as voice over internet protocol (VoIP) service;

(3) Services that generate rare small data packets, such as presence services;

(4) Automatic neighbor relation (ANR) measurement.

In the above scenario, the terminal device is used for a small amount of time or number of times, and most of the time is in the off-screen state. At this time, the power consumption of the modem (modem) accounts for a relatively high proportion of the overall power consumption. , Usually make the terminal device enter the DRX state, for example, you can make the terminal device enter the C-DRX state, after entering the C-DRX state, the terminal device only needs to monitor the PDCCH during the activation period, and does not need to monitor the PDCCH during the sleep period, which can reduce the terminal device detection PDCCH The energy consumption, and then can achieve the purpose of saving electricity. Currently, the DRX cycle used when the terminal device enters the C-DRX state can be pre-configured by the network device according to the initial service state of the terminal device, and the service state of the terminal device changes in real time. If the service state of the subsequent terminal device changes, The DRX cycle pre-configured by the network device may no longer be applicable. For example, if the initial service state of the terminal device is no packet transmission, when the terminal device enters the C-DRX state, the network device can configure the DRX long period for the terminal device according to the initial service state, so that the terminal device can enter the deep During the sleep period, the PDCCH can not be monitored for a long time, and if the service status of the terminal device changes, from no data packet transmission to discontinuous small data packet transmission, the terminal device needs to monitor the PDCCH to achieve small Data packet transmission, and because the terminal device is in the C-DRX sleep period for a long time, it cannot monitor the PDCCH for a long time, which causes the terminal device to be unable to transmit small data packets for a long time, resulting in the transmission of these small data packets The delay increases, affecting the transmission efficiency.

Based on the above-mentioned problems, the industry proposes a solution. In this solution, the network device can adaptively change the DRX cycle configured for the terminal device according to the service status information reported by the terminal device in real time/periodically (for example, the terminal device’s traffic). As shown in Figure 2, this solution is adopted. When the terminal device continuously detects the current service status and determines that the current DRX cycle is not applicable to the current service status, the terminal device can send a DRX configuration request message to the network device to request the network device to issue a new DRX cycle for the network device. Furthermore, a new DRX cycle can be issued for the terminal device according to the DRX configuration request message, so that the terminal device can adopt the new DRX cycle to adapt to the current service state. It should be noted here that since the DRX cycle in the existing protocol only includes the short DRX cycle and/or the long DRX cycle, the DRX cycle reconfigured by the network device for the terminal device in this solution can only be the short DRX cycle and/or the long DRX cycle . There are two shortcomings in using this solution to solve the above problems: First, with this solution, every time the current DRX cycle is not applicable to the current service state, the terminal device needs to perform a signaling interaction with the network device to obtain the newly configured DRX cycle. In this way, as the service status changes, the terminal equipment and the network equipment need to continuously carry out signaling interaction, which in turn leads to excessive communication resources, which will cause additional power consumption for both the terminal equipment and the network equipment. In addition, It will increase the number of network equipment scheduling, resulting in more complex implementation of the program. Second, although the network device can adjust the DRX cycle according to the request of the terminal device using this solution, it can only be adjusted between the short DRX cycle and/or the long DRX cycle. For example, the network device can use the DRX cycle according to the request of the terminal device. The short cycle is adjusted to the DRX long cycle, or the network device can be adjusted from the DRX long cycle to the DRX short cycle according to the request of the terminal device, or the network device can be adjusted from the DRX short cycle to the DRX short cycle and the DRX long cycle according to the request of the terminal device Cycle, or network equipment can adjust the DRX long cycle to DRX short cycle and DRX long cycle according to the request of the terminal device. Obviously, the flexibility of adjusting DRX cycle using this solution is low, and it cannot be well adapted to the dynamic changes of terminal equipment Business status.

In view of this, the embodiment of the present application provides a discontinuous reception configuration method to achieve a more flexible adjustment of the discontinuous reception period to adapt to the terminal without increasing additional signaling overhead between network equipment and terminal equipment. The real-time changing business status of the equipment.

Among them, the adjustment step is used to adjust the period of discontinuous reception. The adjustment step length may be, for example, 2ms, 4ms, or 6ms, which is not limited in this application. Both M and N are positive integers greater than or equal to 2. M is the number of consecutive times that a signal needs to be received in each active period of discontinuous reception, and N is the number of consecutive times that no signal needs to be received in each active period of discontinuous reception . M may be 2, 5, 8, or 10, etc., and the application does not limit the specific value of M. N may be 2, 5, 8, or 10, etc., and the application does not limit the specific value of N. The meaning of M and N in this application will be schematically described below with reference to FIG. 5. As shown in FIG. 5, FIG. 5 shows 5 consecutive DRX short cycles. Each DRX short cycle includes an active period and a light sleep period. When the terminal device is in the activation period 1, the activation period 2, the activation period 3, the activation period 4, and the activation period 5, all need to receive a signal. In this case, M in the embodiment of the present application is 5. Still taking Figure 5 as an example, suppose that the terminal device needs to receive signals when it is in active period 1, active period 2 and active period 3. The terminal device does not need to receive signals when it is in active period 4, and it needs to receive signals when it is in active period 5.

In the embodiment of this application, the network device can send the first discontinuous reception configuration parameter to the terminal device through an existing DRX configuration message (DRX config information), and of course, it can also send the first discontinuous reception configuration parameter to the terminal device through a new message. Parameters, this application does not limit this. When the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, it only needs to add the first discontinuous reception configuration parameter to the existing DRX configuration message, that is, it needs to be in the third-generation partnership plan (3rd generation partnership project, 3GPP) The first discontinuous reception configuration parameter is added to the DRX-config information element in protocol 38.331. When the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, in addition to the first discontinuous reception configuration parameter, the DRX configuration message may also include the following content: the initial value of the timer configured for the terminal device, The configured timer may include one or more of the following timers: drx-on duration timer, drx-inactivity timer, drx-HARQ RTT timerDL, drx-HARQ RTT timerUL, drx-retransmission timerDL, drx-retransmission timerUL , Drx-long cycle timer, drx-short cycle timer. Of course, the DRX configuration message may also include other content, which will not be listed here.

In the following, the above multiple timers are introduced.

② drx-inactivity timer, used to indicate the number of consecutive time units after the PDCCH indicates data transmission, or it can be understood as the time for the terminal device to detect the control channel after the control channel for data transmission, or it can be understood as indicating the The number of time units of consecutive control channels after the device detects the control channel indicating data transmission, or it can be understood as indicating that after the terminal device detects the downlink control information (DCI) indicating data transmission, the terminal device detects the control channel time. The terminal device listens to the PDCCH during this time period. The time unit is 1ms. It should be noted that in this application, drx-inactivity timer and inactivity timer have the same meaning as drx inactivity timer, and both refer to the non-continuous reception inactivity timer, but the name is different. In this application, the non-continuous reception inactivity timer The name is not limited.

③drx-HARQ RTT timerDL, used to indicate the minimum number of consecutive time units before the downlink retransmission is received. It can also be understood as the minimum retransmission scheduling interval, which is used to indicate how many time units the next downlink data is sent at the earliest It can be understood that the terminal device does not listen to the PDCCH during the running of the timer. The time unit is an OFDM symbol.

The time unit is an OFDM symbol.

⑤ drx-retransmission timerDL is used to indicate the time for the terminal device to detect the control channel before the downlink data is retransmitted and received, or in other words, it is used to indicate the number of time units of continuous control channels before the downlink data is retransmitted and received. The terminal device needs to listen to the PDCCH during this time. The time unit is a slot.

⑥drx-retransmission timerUL, used to indicate the time when the network device receives data before the uplink data retransmission is received, or in other words, indicates the number of time units of continuous control channels before the uplink data retransmission is received.

For example, the initial value of the timer may be pre-appointed by the network device and the terminal device. The DRX configuration message may be an RRC message. For example, the DRX configuration message may be an RRC setup message or an RRC reestablishment message or an RRC reconfiguration message, a MAC-CE message, or DCI signaling. Of course, it may also be There are no restrictions on other types of messages.

It should be noted that the above timers, for example, drx-long cycle timer, drx-short cycle timer, on duration timer, drx-inactivity timer, HARQ RTT timer, and drx-retransmission timer, are the names used in the LTE system. When the above-mentioned timer is applied to other communication systems, such as 5G or other types of communication systems, other names may also be used. In the embodiment of the present application, the name of the timer is not limited.

Step 102a: The terminal device adjusts the period of discontinuous reception according to the first discontinuous reception configuration parameter.

In the embodiment of the present application, the terminal device may adopt different implementation manners to adjust the period of the discontinuous reception according to the content included in the first discontinuous reception configuration parameter.

In the first possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size and M, and the adjustment step size includes a first step length. Based on this implementation, the terminal device can adjust the period of discontinuous reception in the following way: when the terminal device determines that it needs to receive a signal during the activation period of M continuous discontinuous reception, it reduces the period of discontinuous reception by a first step. .

It can be understood that in the first possible implementation manner, if the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, the first step length and M need to be added to the DRX-config information element.

Based on the first possible implementation manner described above, the terminal device can also count the first count before reducing the period of discontinuous reception by a first step length, and the first count means that signals need to be received during each active period of discontinuous reception. The terminal device determines that the first count is equal to M.

In the embodiments of the present application, there is no limitation on how the terminal device counts the first count. The following uses a counter to count the first count as an example, and the above-mentioned first possible implementation manner will be described with an example.

Refer to FIG. 6, which is a flow chart for implementing a method for adjusting the discontinuous reception period according to an embodiment of this application. In FIG. 6, the first discontinuous reception configuration parameter includes the first step length and M, and the terminal device passes the counter 1 Count the first count as an example. The method includes the following steps:

Step 201: The network device configures a first discontinuous reception configuration parameter for the terminal device. The first discontinuous reception configuration parameter includes the first step length and M.

Step 202: When the terminal device enters the DRX state, set the counter 1 to 0, so that the initial value of the counter 1 is 0. In this example, the terminal device counts the first count through counter 1, and the count value of counter 1 can be understood as the first count.

Step 203: When the terminal device enters the active period of DRX, it is judged whether it needs to receive a signal during the active period, if it needs to receive a signal, execute step 204, and if it does not need to receive a signal, execute step 205.

Step 204: The terminal device adds 1 to the counter 1.

Step 205: The terminal device sets the counter 1 to 0.

Step 206: Determine whether the count value of the counter 1 is equal to M, if the count value of the counter 1 is equal to M, execute step 207, and if the count value of the counter 1 is not equal to M, execute step 203.

In this example, when the counter 1 has been accumulated to M, it can be understood that the count value of the counter 1 is equal to M. At this time, the terminal device can determine that the first count is equal to M, and then the terminal device can determine that the first count is equal to M. It is necessary to receive signals during the activation period.

Step 207: The terminal device reduces the period of discontinuous reception by a first step.

In this example, after the terminal device reduces the period of discontinuous reception by a first step, step 208 may be performed.

Step 208: The terminal device sets the counter 1 to 0.

In a possible implementation based on the above-mentioned Fig. 6, the terminal device reduces the period of discontinuous reception by a first step, and after setting counter 1 to 0, the method shown in Fig. 6 can be executed again. When counter 1 again When accumulated to M, the terminal device can continue to reduce the period of discontinuous reception by a first step length, which can realize the continuous and stepwise reduction of the period of discontinuous reception, and then can flexibly adjust the size of the period of discontinuous reception.

In a second possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size and N, and the adjustment step size includes a second step size. Based on this implementation method, the terminal device can adjust the period of discontinuous reception in the following manner: the terminal device determines that it does not need to receive a signal during the activation period of N consecutive discontinuous receptions, and increases the period of discontinuous reception by a second step. .

It can be understood that, in the second possible implementation manner described above, if the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, the second step size and N need to be added to the DRX-config information element.

Based on the second possible implementation manner described above, the terminal device can also count the second count before increasing the period of discontinuous reception by the second step. The second count means that no signal is required to be received during each active period of discontinuous reception. The terminal device determines that the second count is equal to N.

In the embodiments of the present application, there is no limitation on how the terminal device counts the second count. The following uses a counter to count the second count as an example, and an example is used to describe the above-mentioned second possible implementation manner.

Referring to FIG. 7, it is a flowchart of another method for adjusting the discontinuous reception period provided by this embodiment of the application. In FIG. 7, the first discontinuous reception configuration parameter includes the second step size and N, and the terminal device passes The counter 2 counts the second count as an example. The method includes the following steps:

Step 301: The network device configures a first discontinuous reception configuration parameter for the terminal device. The first discontinuous reception configuration parameter includes a second step size and N.

Step 302: When the terminal device enters the DRX state, the counter 2 is set to 0, so that the initial value of the counter 2 is 0. In this example, the terminal device counts the second count through the counter 2, and the count value of the counter 2 can be understood as the second count.

Step 303: When the terminal device enters the active period of DRX, it is judged whether it needs to receive a signal during the active period. If it does not need to receive a signal, execute step 304, and if it needs to receive a signal, execute step 305.

Step 304: The terminal device increments the counter 2 by 1.

Step 305: The terminal device sets the counter 2 to 0.

Step 306: Determine whether the count value of the counter 2 is equal to N, if the count value of the counter 2 is equal to N, go to step 307, and if the count value of the counter 2 is not equal to N, go to step 303.

In this example, when the counter 2 has been accumulated to N, it can be understood that the count value of the counter 2 is equal to N. At this time, the terminal device can determine that the second count is equal to N, and then the terminal device can determine that the second count is equal to N. No signal is required during the activation period.

Step 307: The terminal device increases the period of discontinuous reception by a second step.

In this example, after the terminal device increases the period of discontinuous reception by the second step, step 308 may be performed.

Step 308: The terminal device sets the counter 2 to 0.

In a possible implementation based on the foregoing Figure 7, the terminal device increases the period of discontinuous reception by a second step, and after setting counter 2 to 0, the method shown in Figure 7 can be executed again. When the counter 2 accumulates again When it reaches N, the terminal device can continue to increase the period of discontinuous reception by a second step length, which can realize the continuous and stepwise increase of the period of discontinuous reception, and can flexibly adjust the size of the period of discontinuous reception.

It should be noted that, in the embodiments of the present application, the first step length and the second step length may be the same or different.

In a third possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size, M and N, and the adjustment step size includes a first step size and a second step size. Based on this implementation, the terminal device can adjust the period of discontinuous reception in the following way: when the terminal device determines that it needs to receive a signal during the activation period of M continuous discontinuous reception, it reduces the period of discontinuous reception by a first step. ; When the terminal device determines that it does not need to receive a signal during the activation period of N consecutive discontinuous receptions, it increases the period of discontinuous reception by a second step. It should be noted that in this implementation manner, if the first step length and the second step length are the same, the first discontinuous reception configuration parameter may only include one of the first step length or the second step length. If the first step length and the second step length are not the same, the first discontinuous reception configuration parameter may include two step lengths, the first step length and the second step length.

It is understandable that in the third possible implementation manner, if the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, when the first step length is different from the second step length, it needs to be configured in the DRX-config information element If the first step length, the second step length, M and N are added to the DRX-config information element, when the first step length is the same as the second step length, the first step length, M and N must be added to the DRX-config information element.

Based on the third possible implementation manner, the terminal device can also count the first count before reducing the period of discontinuous reception by a first step. The terminal device determines that the first count is equal to M; the terminal device determines the period of discontinuous reception Before increasing the second step size, the second count can also be counted, and the terminal device determines that the second count is equal to N.

In the embodiments of the present application, the following uses a counter to count the first count and the second count as an example, and the third possible implementation manner described above is described with an example.

Referring to FIG. 8, which is a flowchart of another method for adjusting the discontinuous reception period provided by this embodiment of the application, in FIG. 8, the first discontinuous reception configuration parameter includes the adjustment step size, M and N, and the terminal device Take counter 1 to count the first count, and counter 2 to count the second count as an example. In FIG. 8, the first step length and the second step length are the same as an example. In the method shown in FIG. 8, adjusting the step length may include the first step length or the second step length. The method includes the following steps:

Step 401: The network device configures a first discontinuous reception configuration parameter for the terminal device, where the first discontinuous reception configuration parameter includes an adjustment step, M and N.

Step 402: When the terminal device enters the DRX state, the counter 1 is set to 0, so that the initial value of the counter 1 is 0, and the counter 2 is set to 0, so that the initial value of the counter 2 is 0. In this example, the terminal device counts the first count through counter 1, and the count value of counter 1 can be understood as the first count; the terminal device counts the second count through counter 2, and the count value of counter 2 can be understood as the second count .

Step 403: When the terminal device enters the active period of DRX, it is judged whether it needs to receive a signal during the active period. If it needs to receive a signal, it executes steps 404a and 404b. If it does not need to receive a signal, executes steps 404c and 404d.

Step 404a: The terminal device sets the counter 2 to 0.

Step 404b: The terminal device adds 1 to the counter 1.

Step 404c: The terminal device increments the counter 2 by 1.

Step 404d: The terminal device sets the counter 1 to 0.

Step 405a: Determine whether the count value of the counter 1 is equal to M, if the count value of the counter 1 is equal to M, perform step 406a, and if the count value of the counter 1 is not equal to M, perform step 403.

Step 406a: The terminal device reduces the period of discontinuous reception by an adjustment step.

Step 407a: The terminal device sets the counter 1 to 0.

Step 405b: Determine whether the count value of the counter 2 is equal to N, if the count value of the counter 2 is equal to N, execute step 406b, and if the count value of the counter 2 is not equal to N, execute step 403.

Step 406b: The terminal device increases the period of discontinuous reception by an adjustment step.

Step 407b: The terminal device sets the counter 2 to 0.

In a possible implementation based on the foregoing Figure 8, the terminal device reduces the period of discontinuous reception by the adjustment step, and after setting counter 1 to 0, the method shown in Figure 8 can be executed again. When the counter 1 accumulates again At M, the terminal device can continue to reduce the period of discontinuous reception by a first step length, which can realize the continuous and stepwise reduction of the period of discontinuous reception, and can flexibly adjust the size of the period of discontinuous reception. The terminal device increases the period of discontinuous reception by the adjustment step, and after setting counter 2 to 0, the method shown in Figure 8 can be executed again. When the counter 2 accumulates to N again, the terminal device can continue the period of discontinuous reception. Increasing the second step size can realize the continuous and stepwise increase of the period of discontinuous reception, and the size of the period of discontinuous reception can be flexibly adjusted.

Step 102b: The network device adjusts the period of discontinuous reception according to the first discontinuous reception configuration parameter.

In the embodiment of the present application, the method for the network device to adjust the period of discontinuous reception according to the first discontinuous reception configuration parameter is similar to the method for the terminal device to adjust the period of discontinuous reception according to the first discontinuous reception configuration parameter. According to different contents included in the first discontinuous reception configuration parameter, the network device may also adopt different implementation manners to adjust the period of discontinuous reception.

In the first possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size and M, and the adjustment step size includes a first step length. Based on this implementation, the network device can adjust the period of discontinuous reception in the following way: when the network device determines that the terminal device needs to receive a signal during the activation period of M continuous discontinuous reception, it reduces the period of discontinuous reception by the first Stride.

It can be understood that since the terminal device receives the signal is scheduled by the network device, the network device can know whether the terminal device needs to receive the signal every time the terminal device is in the non-continuous reception activation period.

Based on the first possible implementation manner, the network device can also count the first count before reducing the period of discontinuous reception by the first step. The first count is that the terminal device needs to be in each activation period of discontinuous reception. For the consecutive number of received signals, the network device determines that the first count is equal to M.

In the embodiments of this application, there is no limitation on how the network device counts the first count. The network device can also count the first count through counter 1 as in the example of FIG. 6 above. For details about how to count, please refer to the description in FIG. 6, and terminal device statistics. The method of the first counting is similar, and will not be repeated here. With this method, both the terminal device and the network device can count the first count through counter 1, and the terminal device and the network device can synchronously reduce the period of discontinuous reception by a first step when determining that the first count is equal to M. In this way, as long as the network device configures the terminal device with the first discontinuous reception configuration parameter at the initial moment, subsequently, no signaling interaction is required between the terminal device and the network device, and the terminal device can synchronize the discontinuous reception period with the network device.

In a second possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size and N, and the adjustment step size includes a second step size. Based on this implementation, the network device can adjust the period of discontinuous reception in the following manner: the network device determines that the terminal device does not need to receive a signal during the activation period of N consecutive discontinuous reception, and increases the period of discontinuous reception by a second Stride.

Based on the second possible implementation manner described above, the network device may also count the second count before increasing the period of discontinuous reception by the second step, and the network device determines that the second count is equal to N.

The embodiment of this application does not limit how the network device counts the second count. The network device can also use the counter 2 to count the second count like the example shown in FIG. 7 above. For details, please refer to the description in FIG. 7 and the terminal device statistics. The second counting method is similar and will not be repeated here. With this method, both the terminal device and the network device can count the second count through the counter 2. The terminal device and the network device can synchronously increase the period of discontinuous reception by the second step when determining that the second count is equal to N. In this way, as long as the network device configures the terminal device with the first discontinuous reception configuration parameter at the initial moment, subsequently, no signaling interaction is required between the terminal device and the network device, and the terminal device can synchronize the discontinuous reception period with the network device.

In a third possible implementation manner, the first discontinuous reception configuration parameter includes an adjustment step size, M and N, and the adjustment step size includes a first step size and a second step size. Based on this implementation, the network device can adjust the period of discontinuous reception in the following way: when the network device determines that the terminal device needs to receive a signal during the activation period of M continuous discontinuous reception, it reduces the period of discontinuous reception by the first Step size: When the network device determines that the terminal device does not need to receive a signal during the activation period of N consecutive discontinuous receptions, it increases the period of discontinuous reception by a second step. It should be noted that in this implementation manner, if the first step length and the second step length are the same, the first discontinuous reception configuration parameter may only include one of the first step length or the second step length. If the first step length and the second step length are not the same, the first discontinuous reception configuration parameter may include two step lengths, the first step length and the second step length.

Based on the third possible implementation manner, the network device can also count the first count before reducing the period of discontinuous reception by the first step length, and the network device determines that the first count is equal to M; the network device determines the period of discontinuous reception Before increasing the second step size, the second count can also be counted, and the network device determines that the second count is equal to N.

In the embodiment of the present application, the network device may also use the counter 1 to count the first count and the counter 2 to count the second count as in the above example of FIG. 8. For specific statistics, refer to the description in FIG. 8 and will not be repeated here. Through this method, both the terminal device and the network device can count the first count through counter 1. The terminal device and the network device can synchronously reduce the period of discontinuous reception by a first step when determining that the first count is equal to M, and, Both the terminal device and the network device can count the second count through the counter 2. When the terminal device and the network device determine that the second count is equal to N, the period of discontinuous reception can be increased by the second step synchronously. The terminal device is configured with the first discontinuous reception configuration parameter, and subsequently, without signaling interaction between the terminal device and the network device, the terminal device can synchronize the discontinuous reception period with the network device.

It should be noted that the order of performing step 102a and step 102b is not limited in the embodiment of the present application. For example, in a possible implementation manner, step 102a is performed first, and then step 102b is performed. In another possible implementation manner, step 102b is performed first, and then step 102a is performed. In another possible implementation manner, step 102a and step 102b are performed simultaneously.

With the method provided in this application, the network device only needs to configure the discontinuous reception configuration parameters for the terminal device once to realize the adaptive adjustment of the discontinuous reception cycle, without the need for additional signaling interaction between the terminal device and the network device. The signaling overhead can be saved. In addition, the use of this method to adjust the period of discontinuous reception is not limited to adjusting the period of discontinuous reception between the DRX short period and/or the DRX long period. This method can be used to adjust the DRX short period or DRX period. The long period increases or decreases the adjustment step size, and the adjustment step size in this application is not limited, so the flexibility of adjusting the period of discontinuous reception by the method of this application is higher.

In some possible scenarios, when the network device determines that it fails to send a signal to the terminal device, there may be a situation in which the terminal device has adjusted the period of discontinuous reception, but the network device has not adjusted the period of discontinuous reception. This will cause the terminal device to communicate with the network. The DRX configuration between devices is not uniform, which may cause subsequent data transmission errors and affect transmission efficiency. Based on this, in the embodiment of the present application, when the network device determines that the first condition is met, it may also send the reconfigured second discontinuous reception configuration parameter to the terminal device, and the terminal device may receive the second discontinuous reception configuration from the network device Parameter. After receiving the second discontinuous reception configuration parameter, the terminal device may also use the second discontinuous reception configuration parameter to update the first discontinuous reception configuration parameter. In this way, it can be ensured that the DRX configuration parameters between the terminal device and the network device are consistent, and the discontinuous reception configuration parameters between the terminal device and the network device can be avoided from being misaligned.

Among them, the first condition includes but is not limited to at least one of the following:

Item 1: The network device determines that it has failed to send a signal to the terminal device.

Exemplarily, the network device can determine whether there is a data packet loss through the acknowledgement (ACK) or negative acknowledgement (NACK) fed back by the terminal device. When there is a data packet loss, the network device can determine to send a signal to the terminal device If it fails, at this time, the network device may send the reconfigured second discontinuous reception configuration parameter to the terminal device to ensure that the discontinuous reception configuration parameter between the network device and the terminal device can be aligned.

Exemplarily, the network device may also determine that it fails to send a signal to the terminal device through a notification message of the terminal device. For example, suppose the network device is configured with DAI and T-DAI for the terminal device. The terminal device can determine whether there is a data packet loss through DAI and T-DAI. If there is a data packet loss, it can notify the network device through a notification message, and then the network device It can be determined according to the notification message that the signal to the terminal device has failed.

Item 2: The signal transmission time between the network device and the terminal device reaches the first threshold. In this way, the network device and the terminal device can agree to perform a discontinuous reception configuration parameter alignment when the signal transmission time reaches the first threshold, which can ensure that the DRX configuration between the terminal device and the network device is consistent and avoid communication errors.

The discontinuous reception configuration method described above in this application is used for discontinuous reception configuration to adapt to the real-time changing service status of the terminal device. In addition to this technical problem, there is another technical problem in the prior art. In the prior art, network equipment configures a unified drx-inactivity timer for terminal equipment, and the unified drx-inactivity timer cannot meet the service requirements of all terminal equipment. How to configure drx-inactivity timer to meet the service requirements of different terminal equipment is a need Another technical problem solved.

Based on this, the embodiments of the present application provide another discontinuous reception configuration method and device to flexibly configure the drx-inactivity timer to meet the service requirements of different terminal devices. Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Refer to FIG. 9, which is a flowchart of another discontinuous reception configuration method provided in an embodiment of this application. The method includes the following steps:

Step 501: The terminal device measures the first CQI.

Step 502: The terminal device determines the first drx-inactivity timer corresponding to the first CQI according to the first CQI and the first correspondence. The first correspondence includes a one-to-one correspondence between at least one CQI and at least one drx-inactivity timer. It should be noted that the corresponding relationship in this application can also be understood as a mapping relationship, and the corresponding relationship and the mapping relationship may be described interchangeably below.

In the embodiment of the present application, the size of the CQI in the first correspondence relationship is inversely related to the size of the drx-inactivity timer, and can also be understood as inversely proportional, that is, the larger the value of the CQI in the first correspondence relationship, the greater the value of the CQI The corresponding drx-inactivity timer is smaller.

In this embodiment, the first correspondence may be configured through high-layer signaling or predefined.

In the embodiment of this application, the drx-inactivity timer is configured according to the size of the CQI. Since terminal equipment with low CQI (for example, terminal equipment at the edge of a cell) is more likely to require data retransmission, it requires greater transmission time and transmission times. The above-mentioned method provided in this application is for this part of terminals with low CQI The device is configured with a larger drx-inactivity timer to increase the transmission time of the part of the terminal equipment with low CQI, thereby increasing the number of transmissions. Through this method, the terminal equipment with low CQI can be configured with a higher drx-inactivity timer to improve transmission effectiveness. Conversely, the modulation and coding scheme (MCS) of the terminal equipment with high CQI is also high, and the coding efficiency is higher, which means that the number of bits that can be transmitted at one time is more. For this part of the terminal equipment with high CQI Data transmission can be completed with less transmission time and transmission times. The above method provided in this application configures a small drx-inactivity timer for this part of terminal equipment with high CQI to reduce the cost of this part of terminal equipment with low CQI. Transmission time, thereby improving transmission efficiency.

In this embodiment, the first correspondence relationship may be presented in the form of a table. See Table 1 for a first correspondence relationship provided in this embodiment of the application. The first correspondence relationship in Table 1 is only for illustrative purposes. The first correspondence in this application is not limited to this.

Table 1

As shown in Table 1, the first correspondence shown in Table 1 includes 10 correspondences. The first correspondence is: when the CQI is 10, the corresponding drx-inactivity timer is 4, and the second correspondence is : When the CQI is 9, the corresponding drx-inactivity timer is 5. The third correspondence is: when the CQI is 8, the corresponding drx-inactivity timer is 10, and the fourth correspondence is: when the CQI is 7 , The corresponding drx-inactivity timer is 20, the fifth correspondence is: when the CQI is 6, the corresponding drx-inactivity timer is 30, and the sixth correspondence is: when the CQI is 5, the corresponding drx-inactivity The timer is 40, the seventh correspondence is: when the CQI is 4, the corresponding drx-inactivity timer is 50, and the eighth correspondence is: when the CQI is 3, the corresponding drx-inactivity timer is 60, and the ninth One correspondence is: when the CQI is 2, the corresponding drx-inactivity timer is 80, and the tenth correspondence is: when the CQI is 1, the corresponding drx-inactivity timer is 100.

Taking the first correspondence shown in Table 1 as an example, the method in FIG. 9 described above will be described. Assuming that the first CQI measured by the terminal device in step 501 is 6, the terminal device can determine that the first drx-inactivity timer corresponding to the first CQI is 30 according to the first correspondence in Table 1.

It should be noted that since CQI is an instantaneous variable, it is greatly affected by the channel in a time-varying scenario. Therefore, in a time-varying scenario, the CQI refers to the average value of the CQI over a period of time.

Step 503: The terminal device sends the first CQI to the network device, and the network device receives the first CQI from the terminal device.

Step 504: The network device determines the first drx-inactivity timer corresponding to the first CQI according to the first CQI and the first correspondence.

This embodiment does not limit the execution sequence of step 502 and step 503. For example, in a possible implementation manner, step 502 is performed first, and then step 503 is performed. In another possible implementation manner, step 503 is performed first, and then step 502 is performed. In another possible implementation manner, step 502 and step 503 are performed simultaneously.

Regarding the discontinuous reception configuration, in addition to the above two technical problems, there is another technical problem in the prior art. In the prior art, terminal devices in the DRX sleep period may undergo abrupt changes such as rotation or translation or obscuration, resulting in some terminal devices entering the DRX active period from the DRX sleep period, and the beams of the terminal devices and the network device The beams may not be aligned, which may result in that some terminal devices cannot effectively monitor the PDCCH. Therefore, how to ensure that the beam of the terminal device is aligned with the beam of the network device after the terminal device enters the DRX activation period is another technical problem that needs to be solved.

Based on this, the embodiments of this application provide yet another discontinuous reception configuration method and device, by which the terminal device can wake up in the last short period of the sleep period and perform beam selection, so that the beam of the terminal device and the network device The beam alignment of the terminal device can then ensure that the beam of the terminal device is aligned with the beam of the network device after the terminal device enters the DRX activation period. Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

It should be noted that this embodiment can be applied to 5G millimeter wave scenarios, and of course, it can also be applied to other scenarios, which is not limited in this application. When this embodiment is applied to a 5G millimeter wave scenario, the terminal device in the embodiment of the present application refers to a millimeter wave terminal device, and can also be understood as a terminal device using millimeter waves.

Refer to FIG. 10, which is a flowchart of another discontinuous reception configuration method provided by an embodiment of this application. The method includes the following steps:

Step 601: The terminal device determines a first speed level, where the first speed level represents how fast the terminal device moves or rotates.

In the embodiment of the present application, the terminal device may detect the moving speed through a sensor accelerometer, and may detect the rotation speed through a gyroscope. After detecting the moving speed and/or the rotation speed, the terminal device may further determine the first speed according to the moving speed and/or the rotation speed. Speed rating. Exemplarily, the terminal device may determine the speed level corresponding to the measured movement speed and/or rotation speed according to the corresponding relationship between the movement speed and/or the rotation speed and the speed level.

In a possible implementation manner, the terminal device may determine the moving speed or the rotating speed, and send the moving speed or the rotating speed to the network device, and the network device determines which speed the moving speed or the rotating speed belongs to according to a preset rule grade. For example, suppose that the terminal device determines that the moving speed is 9 (just as an indication), and then can send the moving speed to the network device, and the network device can determine according to the correspondence between the moving speed and the speed level stored in advance, as shown in Table 2. The speed level corresponding to this movement speed 9 is high speed.

Step 602: The terminal device sends the first speed grade to the network device, and the network device receives the first speed grade from the terminal device.

In the embodiment of this application, the terminal device may send the first speed level to the network device through the existing UE assistance information message, and of course, it may also send the first speed level to the network device through a new message, which is not limited in this application. When the terminal device sends the first speed level through the UE assistance information message, a new field-the speed level of the terminal device (for example, UE-speed), needs to be added to the existing UE assistance information message. Specifically, this field can correspond to multiple Levels, such as low speed, high speed, medium speed, and stationary.

It should be noted that in the embodiment of the present application, if the terminal device is in a static state during the sleep period, the problem of beam misalignment will not occur, and the method of the present application does not need to be used for beam alignment.

Step 603: The network device determines a first pre-wake-up-window corresponding to the first speed class and the first number of beams according to the first speed class, the first number of beams of the terminal device, and the second correspondence. ), the second correspondence includes a one-to-one correspondence of at least one speed level, at least one number of beams, and at least one pre-preparation time, the pre-preparation time is a period of time before the activation period of discontinuous reception, and the terminal device is within the pre-preparation time You can wake up from sleep for beam selection.

In the embodiment of the present application, the pre-preparation time is a period of time before the activation period of discontinuous reception. It can also be understood that the pre-preparation time is a period of time included in the sleep period of discontinuous reception. As shown in FIG. 11, this application Another possible C-DRX mode flow diagram is provided. The C-DRX mode in Fig. 11 is a mode in which the preparation time is configured using the method shown in Fig. 10 of this application. It can be seen from Fig. 11 that in the C-DRX state Next, the period before the activation period, that is, the last period included in the sleep period, is the preparation time.

In the embodiment of the present application, the size of the number of beams in the second correspondence is positively correlated with the length of the pre-preparation time, which can also be understood as being proportional, that is, the more the number of beams in the second correspondence, the more the number of beams corresponds to The longer the preparation time. In addition, the speed represented by the speed level in the second correspondence is positively correlated with the length of the pre-preparation time, which can also be understood as proportional, that is, the greater the speed represented by the speed level in the second correspondence, the greater the speed with the speed level The corresponding preparation time is longer.

Exemplarily, the second correspondence may be configured through high-level signaling or predefined.

In this embodiment, the second correspondence relationship may be presented in the form of a table. See Table 3, which is a second correspondence relationship provided in this embodiment of the present application. The second correspondence relationship in Table 3 is only for illustrative purposes. The second correspondence in this application is not limited to this.

table 3

As shown in Table 3, the second correspondence shown in Table 3 includes 9 correspondences. The first correspondence is: when the number of beams of the terminal device is less than 10, and the speed class is low speed, the corresponding preparation time is The last 1/6 of the sleep period, the second corresponding relationship is: when the number of beams of the terminal device is less than 10, and the speed level is medium speed, the corresponding pre-preparation time is the last 1/5 of the sleep period, and the third The corresponding relationship is: when the number of beams of the terminal device is less than 10 and the speed class is high-speed, the corresponding pre-preparation time is the last 1/4 of the sleep period, and the fourth corresponding relationship is: when the number of beams of the terminal device is greater than or equal to 10 When the speed level is less than or equal to 20 and the speed level is low, the corresponding pre-preparation time is the last 1/5 of the sleep period. The fifth correspondence is: when the number of beams of the terminal device is greater than or equal to 10 and less than or equal to 20, the speed level is medium speed When the corresponding pre-preparation time is the last 1/4 of the sleep period, the sixth correspondence is: when the number of beams of the terminal device is greater than or equal to 10 and less than or equal to 20, and the speed level is high-speed, the corresponding pre-preparation time is sleep In the last 1/3 of the period, the seventh correspondence is: when the number of beams of the terminal device is greater than 20 and the speed level is low, the corresponding pre-preparation time is the last 1/4 of the sleep period, and the eighth correspondence As: when the number of beams of the terminal device is greater than 20 and the speed level is medium speed, the corresponding pre-preparation time is the last 1/3 of the sleep period. The ninth correspondence is: when the number of beams of the terminal device is greater than 20, the speed When the level is high speed, the corresponding pre-preparation time is the last 1/2 time of the sleep period.

Taking the second correspondence shown in Table 3 as an example, the method shown in FIG. 10 will be described. Assuming that the first speed class determined by the terminal device in step 601 is low speed, and the beam of the terminal device is 6, then the network device in step 603 can be based on the first speed class, the first number of beams of the terminal device, and the second correspondence, It is determined that the first pre-preparation time corresponding to the first speed level and the first number of beams is the last 1/6 time of the sleep period.

Step 604: The network device sends the first preparation time to the terminal device, and the terminal device receives the first preparation time from the network device.

In this embodiment, after receiving the first preparation time from the network device, the terminal device may wake up from the sleep period at the first preparation time to perform beam selection.

Step 605: The terminal device wakes up within the first pre-preparation time, and performs beam selection, so that the reselected beam is aligned with the beam of the network device.

In the embodiments of the present application, for the terminal device to perform beam selection, reference may be made to the related description in 7) of the above-mentioned part of the terminology explanation, which is not repeated here. The beam selection performed by the terminal device may include processes such as beam determination, beam measurement, beam scanning, and beam reporting, so that the reselected beam is finally aligned with the beam of the network device.

Based on the same inventive concept, an embodiment of the present application also provides a terminal device. The terminal device may have a structure as shown in FIG. 12 and have the behavioral functions of the terminal device in the foregoing method embodiment. As shown in FIG. 12, the terminal device 1200 may include a transceiving unit 1201 and a processing unit 1202. The transceiving unit 1201 may be used to receive the first discontinuous reception configuration parameter from a network device, and the processing unit 1202 may be used to The first discontinuous reception configuration parameter adjusts the period of the discontinuous reception. Alternatively, the processing unit 1202 may be configured to measure the first CQI, and may also be configured to determine the first drx-inactivity timer corresponding to the first CQI according to the first CQI and the first corresponding relationship. The transceiver unit 1201 may be configured to send the first CQI to a network device. Alternatively, the processing unit 1202 may be used to determine a first speed level, the transceiving unit 1201 may be used to send the first speed level to a network device, and the transceiving unit 1201 may also be used to receive data from the network device. The processing unit 1202 may also be configured to perform beam selection according to the first pre-preparation time. In implementation, the terminal device 1200 may also have a storage unit 1203, which may be coupled with the processing unit 1202, and used to store programs and instructions required by the processing unit 1202 to perform functions.

Wherein, the first discontinuous reception configuration parameter includes an adjustment step size, and the first discontinuous reception configuration parameter includes M and/or N, wherein the adjustment step size is used to adjust the period of discontinuous reception, The M and the N are both positive integers greater than or equal to 2, the M is the number of consecutive times that a signal needs to be received in each active period of the discontinuous reception, and the N is The activation period of the reception does not require consecutive times of receiving the signal.

In a possible design, the first discontinuous reception configuration parameter includes the adjustment step size and the M, and the adjustment step size includes the first step size. Based on this design, the processing unit 1202 is specifically configured to: determine that when a signal needs to be received during the activation periods of the M consecutive discontinuous receptions, reduce the period of the discontinuous reception by the first step length.

In a possible design, the processing unit 1202 is further configured to:
