Description

Configuration method and device for discontinuous reception

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for configuring discontinuous reception.

Background

Currently, in a wireless communication system, such as a Long Term Evolution (LTE) communication system and a fifth generation (5G) communication system, a connected-discontinuous reception (C-DRX) mechanism is introduced, in which a terminal device periodically enters a sleep state (or referred to as a sleep mode or a sleep period, etc.) when in a Radio Resource Control (RRC) connected state, and does not monitor a Physical Downlink Control Channel (PDCCH) in the sleep state, and wakes up (wake up) from the sleep state to enter an active state (or referred to as an active period or an active mode, etc.) when monitoring the PDCCH is needed, so as to achieve a power saving purpose.

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

And/or the first discontinuous reception configuration parameter comprises an adjustment step length and N, the adjustment step length comprises a second step length, the terminal equipment increases the discontinuous reception period by the second step length when determining that the signal does not need to be received in the activation periods of the continuous N discontinuous receptions, and the network equipment increases the discontinuous reception period by the second step length when determining that the signal does not need to be received in the activation periods of the continuous N discontinuous receptions.

The adjustment step length is used for adjusting the discontinuous reception period, M and N are positive integers greater than or equal to 2, M is the continuous times that the terminal equipment needs to receive signals in each discontinuous reception activation period, and N is the continuous times that the terminal equipment does not need to receive signals in each discontinuous reception activation period.

By the method, the network equipment can realize the self-adaptive adjustment of the discontinuous reception cycle only by configuring the discontinuous reception configuration parameters for the terminal equipment once, and extra signaling interaction between the terminal equipment and the network equipment is not needed, so that the signaling overhead can be saved.

In one possible design, before the terminal device reduces the discontinuous reception period by the first step length, the method further includes: the terminal equipment counts a first count, wherein the first count is the continuous times of receiving signals in each activation period of discontinuous reception; the terminal device determines that the first count is equal to M.

The base station can realize the functions of protocol layers such as RRC, PDCP, RLC, MAC and the like by one node; or the functions of these protocol layers may be implemented by multiple nodes; for example, in an evolved structure, a base station may include a Centralized Unit (CU) and a Distributed Unit (DU), and a plurality of DUs may be centrally controlled by one CU. The CU and the DU may be divided according to protocol layers of the radio network, for example, functions of a PDCP layer and above protocol layers are provided in the CU, and functions of protocol layers below the PDCP layer, for example, functions of an RLC layer and a MAC layer, are provided in the DU.

This division of the protocol layers is only an example, and it is also possible to divide the protocol layers at other protocol layers, for example, at the RLC layer, and the functions of the RLC layer and the protocol layers above are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; alternatively, the functions are divided into some protocol layers, for example, a part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are provided in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.

In addition, the radio frequency device may be pulled away, not placed in the DU, or integrated in the DU, or partially pulled away and partially integrated in the DU, which is not limited herein.

Alternatively, the Control Plane (CP) and the User Plane (UP) of the CU may be separated and implemented by being divided into different entities, namely a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity).

In the above network architecture, the signaling generated by the CU may be transmitted to the terminal through the DU, or the signaling generated by the terminal may be transmitted to the CU through the DU. The DU may pass through the protocol layer encapsulation directly to the terminal or CU without parsing the signaling. In the following embodiments, if transmission of such signaling between the DU and the terminal is involved, in this case, the transmission or reception of the signaling by the DU includes such a scenario. For example, the signaling of the RRC or PDCP layer is finally processed as the signaling of the PHY layer to be transmitted to the terminal, or converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered to be sent by the DU, or by the DU and the radio frequency.

In the above embodiment, the CU is divided into network devices on the Radio Access Network (RAN) side, and in addition, the CU may also be divided into network devices on the Core Network (CN) side, which is not limited herein.

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

3) And DRX, under the DRX mechanism, the terminal equipment stops monitoring the PDCCH in a sleep period. According to the working state of the DRX, the DRX can be divided into two types: IDLE state (IDLE) DRX and CONNECTED state (CONNECTED) C-DRX.

IDLE DRX refers to discontinuous reception when a terminal device is in an IDLE state, and since there is no RRC connection and no dedicated resource of the terminal device when the terminal device is in the IDLE state, the terminal device mainly monitors a paging message in IDLE DRX, and the purpose of discontinuous reception can be achieved as long as the period of the paging message is defined. When the terminal device monitors the user data, it leaves the idle state, for example, it enters the connection state from the idle state first.

C-DRX refers to DRX of the terminal equipment in an RRC connection state. In the C-DRX mode, the terminal device may be in multiple states, as shown in fig. 1, which is one possible C-DRX mode procedure, in the procedure shown in fig. 1, the terminal device may be in an active period (on duration) or a sleep period, where the sleep period may include a short sleep period (short sleep) and a deep sleep period (long sleep), and the terminal device may monitor the PDCCH in the active period and stop monitoring the PDCCH in the sleep period to reduce energy consumption for the terminal device to detect the PDCCH. The sleep period may also be referred to as a sleep state or an OFF (OFF) state.

4) The discontinuous reception cycle (DRX cycle) may include a DRX long cycle (long DRX cycle) and a DRX short cycle (short DRX cycle), wherein the DRX long cycle is an integer multiple of the DRX short cycle. Whether it is a DRX long cycle or a DRX short cycle, one DRX cycle is equal to the sum of an active period (which may be referred to as a wake-up time) and a sleep period (which may be referred to as a sleep time), as shown in fig. 1. In each DRX cycle, the terminal device wakes up in the active period to monitor the PDCCH, and stops monitoring the PDCCH in the sleep period. The network device can configure a DRX short cycle and a DRX long cycle for the terminal device, when the DRX short cycle is finished, the terminal device can enter the DRX long cycle, the network device can also only configure the DRX long cycle for the terminal device and not configure the DRX short cycle, and the configuration conditions of the DRX long cycle and the DRX short cycle are determined according to actual use requirements. In the present application, the DRX long cycle may also be described as a long DRX cycle, and the DRX short cycle may also be described as a short DRX cycle, where the name of the DRX cycle is not limited in the present application.

5) The signal, in the embodiment of the present application, may include data and/or control signaling. Accordingly, the signal to be received may be understood as data and/or control signaling to be received; the absence of a received signal may be understood as the absence of received data and/or control signaling.

6) A time unit, is a unit of time. For example, the OFDM symbol may include one or more consecutive Transmission Time Intervals (TTIs), slots (slots), time domain symbols (symbols), subframes, Orthogonal Frequency Division Multiplexing (OFDM) symbols, and so on, where a slot may be a full slot or a mini slot (or non-slot) containing less than 14 OFDM symbols, and one mini slot may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, or 13 OFDM symbols.

7) Beam management profile for millimeter waves

The 5G NR mainly forms signal beams through an antenna array, realizes that accurate narrow beams provide service for user data, can obtain longer coverage distance and reduces interference.

Beam management is a protocol basic characteristic of millimeter waves, and in TR38.802, a key process of beam management is defined: the L1/L2 process for acquiring and maintaining the uplink and downlink data transmission and reception beam sets comprises beam determination, beam measurement, beam scanning and beam reporting.

(1) The beam determination refers to a process of selecting an appropriate transmission/reception beam by the TRP or the UE. The requirements of the UE side are as follows: the UE performs an alignment process after receiving the millimeter wave beams on the network equipment side, wherein the alignment process comprises downlink beam and uplink beam selection, and finally selects the optimal beam, and the UE needs to meet beam reciprocity.

(2) The beam measurement refers to a shaped signal received by the UE from the network equipment side, the shaped signal includes beam information, and the requirements of the UE side are as follows: the method can accurately measure the beam forming signals of the network, can accurately report the beam measuring signals, and can execute other actions of beam management according to the measuring result.

(3) Beam scanning, which refers to the transmission and/or reception of beams in a predetermined manner at certain time intervals over a spatial area. The requirements of the UE side are as follows: the UE may scan the beam for a certain time and correctly process the scanning result.

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

8) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present application. "at least one" is to be understood as meaning one or more, for example one, two or more. For example, including at least one means 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 including may 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, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

Unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects.

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

(1) delay insensitive, and there is not a service that data needs to be received and sent at most times, for example, browsing a web page, sending and receiving an email (email), or through a File Transfer Protocol (FTP);

(2) a periodic continuous small packet service, in which data transmission is regular, such as a voice over internet protocol (VoIP) service;

(3) services that generate rare small packets, such as Presence services;

(4) automatic Neighbor Relation (ANR) measurement.

In the above scenario, the service time or the number of times of the terminal device is small, and most of the time is in the screen-off state, and the power consumption of a modem (modem) in the power consumption of the whole terminal device is relatively high, so as to reduce the power consumption of the terminal device in the above scenario, the terminal device usually enters the DRX state, for example, the terminal device can enter the C-DRX state, and after entering the C-DRX state, the terminal device only needs to monitor the PDCCH in the active period, and does not need to monitor the PDCCH in the sleep period, so that the power consumption of the terminal device for detecting the PDCCH can be reduced, and the purpose of saving power can be. At present, a DRX cycle used when a terminal device enters a C-DRX state may be preconfigured by a network device according to an initial service state of the terminal device, and a service state of the terminal device changes in real time, and if a service state of a subsequent terminal device changes, the DRX cycle preconfigured by the network device may no longer be applicable. For example, if the initial service state of the terminal device is no packet transmission, and at this time the terminal device enters the C-DRX state, the network device may configure a DRX long period for the terminal device according to the initial service state, so that the terminal device may enter a deep sleep period, and may not monitor the PDCCH for a long time, and if the subsequent service state of the terminal device changes, the no packet transmission changes into discontinuous small packet transmission, and at this time the terminal device needs to monitor the PDCCH to implement transmission of the small packet, and since the terminal device is in the C-DRX sleep period for a long time, the terminal device cannot monitor the PDCCH for a long time, and thus the terminal device cannot transmit the small packet for a long time, resulting in an increase in transmission delay of the small packets, and affecting transmission efficiency.

Based on the above existing problems, the industry proposes a solution. In this scheme, the network device may adaptively change the DRX cycle configured by the terminal device according to the service state information (for example, the traffic of the terminal device) reported by the terminal device in real time/periodically, as shown in fig. 2, with the scheme, the terminal device continuously detects the current service state, and when it is determined that the current DRX cycle is not applicable to the current service state, the terminal device may send a DRX configuration request message to the network device for requesting the network device to issue a new DRX cycle for the terminal device, and the network device may further issue the new DRX cycle for the terminal device according to the DRX configuration request message, so that the terminal device may 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 DRX short cycle and/or the DRX long cycle, the DRX cycle that the network device reconfigures for the terminal device in this scheme can only be the DRX short cycle and/or the DRX long cycle. Two defects exist in the scheme for solving the problems: firstly, by adopting the scheme, each time the current DRX cycle is not applicable to the current service state, the terminal device needs to perform signaling interaction with the network device once to obtain the newly configured DRX cycle, so that along with the change of the service state, signaling interaction needs to be performed between the terminal device and the network device continuously, thereby causing the occupation of excessive communication resources, causing extra power consumption for both the terminal device and the network device, and increasing the scheduling times of the network device, thereby causing the implementation of the scheme to be complex. Secondly, although the network device may adjust the DRX cycle according to the request of the terminal device, the network device may only adjust between the DRX short cycle and/or the DRX long cycle, for example, the network device may adjust the DRX short cycle to the DRX long cycle according to the request of the terminal device, or the network device may adjust the DRX long cycle to the DRX short cycle according to the request of the terminal device, or the network device may adjust the DRX short cycle to the DRX short cycle and the DRX long cycle according to the request of the terminal device, or the network device may adjust the DRX long cycle to the DRX short cycle and the DRX long cycle according to the request of the terminal device, and obviously, the flexibility of adjusting the DRX cycle is low, and the network device cannot be well adapted to the service state of the terminal device that changes dynamically.

In view of this, an embodiment of the present application provides a configuration method for discontinuous reception, so as to implement more flexible adjustment of a discontinuous reception period without increasing additional signaling overhead between a network device and a terminal device, so as to adapt to a real-time changing service state of the terminal device.

The technical solution provided in the embodiment of the present application may be applied to a 5G communication system, or an LTE communication system, or may also be applied to a next generation mobile communication system or other similar communication systems, which is not limited in the present application.

The method can correspond to three cases, wherein in the first case, the first discontinuous reception configuration parameter includes an adjustment step size and M, in the second case, the first discontinuous reception configuration parameter includes an adjustment step size and N, and in the third case, the first discontinuous reception configuration parameter includes an adjustment step size, M, and N.

Wherein, the step length is used for adjusting the discontinuous reception period. The adjustment step may be, for example, 2ms, 4ms, or 6ms, which is not limited in this application. M and N are positive integers which are more than or equal to 2, M is the continuous times of signals needing to be received in the activation period of each discontinuous reception, and N is the continuous times of signals needing not to be received in the activation period of each discontinuous reception.

In this embodiment of the present application, the network device may send the first discontinuous reception configuration parameter to the terminal device through an existing DRX configuration message (DRX configuration), or certainly, may send the first discontinuous reception configuration parameter to the terminal device through a new message, which is not limited in this application. When the network device sends the first DRX configuration parameter through the DRX configuration message, it only needs to add the first DRX configuration parameter in the existing DRX configuration message, that is, it needs to add the first DRX configuration parameter in the DRX-configuration element in the 3rd generation partnership project (3 GPP) protocol 38.331. When the network device sends the first discontinuous reception configuration parameter through the DRX configuration message, the DRX configuration message may include the following contents in addition to the first discontinuous reception configuration parameter: an initial value of a configured timer for the terminal device, the configured timer may include one or more of the following timers: a drx-on duration timer, a drx-inactivity timer, a drx-HARQ RTT timer DL, a drx-HARQ RTT timer UL, a drx-retransmission timer DL, a drx-retransmission timer UL, a drx-long cycle timer, and a drx-short cycle timer. Of course, other contents may also be included in the DRX configuration message, which is not listed here.

Next, the above-described plurality of timers will be described.

The terminal device listens to the PDCCH during this time period. The time unit is 1 ms. It should be noted that, in the present application, the drx-inactivity timer and the inactivity timer have the same meaning, and both refer to the drx inactivity timer and are only different in name, and the name of the drx inactivity timer is not limited in the present application.

drx-HARQ RTT timer dl is used to indicate the minimum number of consecutive time units before downlink retransmission reception, and may also be understood as a minimum retransmission scheduling interval, that is, to indicate how many time units the next downlink data transmission occurs earliest, and may be understood as that, during the operation period of the timer, the terminal device does not monitor the PDCCH. The time unit is one OFDM symbol.

Sixthly, drx-transmission timer ul for indicating the time when the network device receives the data before the uplink data retransmission reception, or indicating the number of time units of the continuous control channel before the uplink data retransmission reception. The time unit is a slot.

And seventhly, DRX-long cycle timer is the life cycle of the long cycle of the DRX mechanism and has a unit of ms.

And the eightfold-short cycle timer is the life cycle of the short cycle of the DRX mechanism, and the unit is ms.

For any of the above timers, the DRX configuration message may not include an initial value of the timer, for example, the initial value of the timer may be pre-agreed 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, an RRC reestablishment message, an RRC reconfiguration message, a MAC-CE message, a DCI signaling, or other types of messages, which is not limited herein.

Note that the above timers, for example, drx-long cycle timer, drx-short cycle timer, duration timer, drx-inactivity timer, HARQ RTT timer, and drx-retransmission timer are names used in the LTE system, and when the above timers are applied to other communication systems, for example, 5G or other types of communication systems, other names may be used, and in the embodiment of the present application, the names of the timers are not limited.

Step 102 a: and the terminal equipment adjusts the discontinuous reception period according to the first discontinuous reception configuration parameter.

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

In a first possible implementation manner, the first drx configuration parameter includes an adjustment step size and M, where the adjustment step size includes a first step size. Based on the implementation manner, the terminal device may adjust the discontinuous reception period in the following manner: and the terminal equipment reduces the discontinuous reception period by a first step length when determining that the signals need to be received in the activation periods of continuous M discontinuous receptions.

It can be understood that, in the first possible implementation manner, if the network device sends the first DRX configuration parameter through the DRX configuration message, the network device needs to add the first step size and M to the DRX-configuration information element.

Based on the first possible implementation manner, before the terminal device decreases the discontinuous reception period by the first step length, the terminal device may further count a first count, where the first count is a continuous number of times that signals need to be received in each activation period of the discontinuous reception, and the terminal device determines that the first count is equal to M.

In the embodiment of the present application, how the terminal device counts the first count is not limited, and the following takes counting the first count by a counter (counter) as an example, and the first possible implementation manner is described with reference to an example.

Referring to fig. 6, which is a flowchart illustrating an implementation of a method for adjusting a drx cycle according to an embodiment of the present disclosure, in fig. 6, a first drx configuration parameter includes a first step size and M, and a terminal device counts a first count through a counter 1. The method comprises the following steps:

step 201: the network equipment configures a first discontinuous reception configuration parameter for the terminal equipment, wherein the first discontinuous reception configuration parameter comprises a first step length and M.

Step 202: 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. In this example, the terminal device counts the first count by the counter 1, and the count value of the counter 1 can be understood as the first count.

Step 203: when the terminal device enters the active period of DRX, it determines whether it needs to receive signals in the active period, if so, executes step 204, and if not, executes step 205.

Step 204: the terminal device increments the counter 1 by 1.

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

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

In this example, when the counter 1 is incremented to M, it can be understood that the count value of the counter 1 is equal to M, at this time, the terminal device may determine that the first count is equal to M, and then the terminal device may determine that signals need to be received in all of M activation periods of discontinuous reception.

Step 207: the terminal equipment reduces the discontinuous reception period by a first step size.

In this example, the terminal device may further perform step 208 after reducing the period of discontinuous reception by the first step size.

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

Based on the foregoing fig. 6, in a possible implementation manner, the terminal device decreases the discontinuous reception cycle by the first step size, and after setting the counter 1 to 0, may execute the method shown in fig. 6 again, when the counter 1 is incremented to M again, the terminal device may continue to decrease the discontinuous reception cycle by the first step size, may implement continuous and step-like decrease of the discontinuous reception cycle, and may further flexibly adjust the size of the discontinuous reception cycle.

In a second possible implementation manner, the first drx configuration parameter includes an adjustment step size and N, where the adjustment step size includes a second step size. Based on the implementation manner, the terminal device may adjust the discontinuous reception period in the following manner: and the terminal equipment increases the discontinuous reception period by a second step length when determining that the signals do not need to be received in the activation periods of the continuous N discontinuous receptions.

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

Based on the second possible implementation manner, before the terminal device increases the discontinuous reception period by the second step length, a second count may be counted, where the second count is the number of consecutive times that the signal does not need to be received in each activation period of the discontinuous reception, and the terminal device determines that the second count is equal to N.

How the terminal device counts the second count is not limited in the embodiment of the present application, and the second possible implementation manner is described below with reference to an example in which the counter (counter) counts the second count.

Referring to fig. 7, which is a flowchart illustrating a further method for adjusting a drx cycle according to an embodiment of the present disclosure, in fig. 7, a first drx configuration parameter includes a second step size and N, and a terminal device counts a second count through a counter 2. The method comprises the following steps:

step 301: and the network equipment configures a first discontinuous reception configuration parameter for the terminal equipment, wherein the first discontinuous reception configuration parameter comprises a second step length 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 by 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 determines whether or not to receive a signal during the active period, and if not, executes step 304, and if so, executes step 305.

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

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

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

In this example, when the counter 2 is incremented up to N, it can be understood that the count value of the counter 2 is equal to N, at this time, the terminal device may determine that the second count is equal to N, and then the terminal device may determine that no signal needs to be received in the activation periods of N consecutive discontinuous receptions.

Step 307: and the terminal equipment increases the discontinuous reception period by a second step length.

In this example, the terminal device may further perform step 308 after increasing the period of discontinuous reception by the second step.

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

Based on the foregoing fig. 7, in a possible implementation manner, the terminal device increases the discontinuous reception period by the second step length, and after setting the counter 2 to 0, may perform the method shown in fig. 7 again, and when the counter 2 is accumulated to N again, the terminal device may continue to increase the discontinuous reception period by the second step length, which may implement continuous and step-like increase of the discontinuous reception period, and may further flexibly adjust the size of the discontinuous reception period.

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

In a third possible implementation manner, the first drx configuration parameter includes an adjustment step size, M, and N, where the adjustment step size includes a first step size and a second step size. Based on the implementation manner, the terminal device may adjust the discontinuous reception period in the following manner: the terminal equipment reduces the discontinuous reception period by a first step length when determining that signals need to be received in the activation periods of continuous M discontinuous reception; and the terminal equipment increases the discontinuous reception period by a second step length when determining that the signals do not need to be received in the activation periods of the continuous N discontinuous receptions. It should be noted that, in this implementation manner, if the first step size and the second step size are the same, the first drx configuration parameter may only include one adjustment step size of the first step size or the second step size, and if the first step size and the second step size are different, the first drx configuration parameter may include two step sizes of the first step size and the second step size.

It can be understood that, in the third possible implementation manner, if the network device sends the first DRX configuration parameter through the DRX configuration message, the first step size, the second step size, M, and N need to be added to the DRX-configuration information element when the first step size is different from the second step size, and the first step size, M, and N need to be added to the DRX-configuration information element when the first step size is the same as the second step size.

Based on the third possible implementation manner, before the terminal device reduces the discontinuous reception period by the first step length, the terminal device may also count the first count, and determine that the first count is equal to M; before the terminal device increases the discontinuous reception period by the second step length, the terminal device may also count a second count, and the terminal device determines that the second count is equal to N.

In the embodiment of the present application, the third possible implementation manner is described below with reference to an example, by taking statistics of the first count and the second count through a counter (counter).

Referring to fig. 8, which is a flowchart illustrating a method for adjusting a drx cycle according to another embodiment of the present disclosure, in fig. 8, a first drx configuration parameter includes an adjustment step size, M, and N, and a terminal device counts a first count through a counter 1 and counts a second count through a counter 2. In fig. 8, the first step size and the second step size are the same as an example, and the step size may be adjusted in the method shown in fig. 8. The method comprises the following steps:

step 401: the network equipment configures a first discontinuous reception configuration parameter for the terminal equipment, wherein the first discontinuous reception configuration parameter comprises an adjustment step length, 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 a first count by the counter 1, and the count value of the counter 1 can be understood as the first count; 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 403: when the terminal device enters the active period of DRX, it determines whether it needs to receive signals in the active period, and if it needs to receive signals, it executes steps 404a and 404b, and if it does not need to receive signals, it executes steps 404c and 404 d.

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

Step 404 b: the terminal device increments the counter 1 by 1.

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

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

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

Step 406 a: and the terminal equipment reduces the discontinuous reception period by the adjustment step length.

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

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

Step 406 b: and the terminal equipment increases the discontinuous reception period by the adjustment step length.

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

Based on the foregoing fig. 8, in a possible implementation manner, the terminal device decreases the discontinuous reception cycle by the adjustment step size, and after setting the counter 1 to 0, may execute the method shown in fig. 8 again, when the counter 1 is accumulated to M again, the terminal device may continue to decrease the discontinuous reception cycle by the first step size, may implement continuous and step-like decrease of the discontinuous reception cycle, and may further flexibly adjust the size of the discontinuous reception cycle. The terminal equipment increases the adjustment step length of the discontinuous reception cycle, and after the counter 2 is set to 0, the method shown in fig. 8 can be executed again, when the counter 2 is accumulated to N again, the terminal equipment can continue to increase the discontinuous reception cycle by the second step length, so that the continuous and step-type increase of the discontinuous reception cycle can be realized, and the size of the discontinuous reception cycle can be flexibly adjusted.

Step 102 b: and the network equipment adjusts the discontinuous reception period according to the first discontinuous reception configuration parameter.

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

In a possible implementation manner of 1, the first discontinuous reception configuration parameter includes an adjustment step size and M, and the adjustment step size includes a first step size. Based on this implementation, the network device may adjust the discontinuous reception period in the following manner: and when the network equipment determines that the terminal equipment needs to receive signals in the activation periods of continuous M discontinuous receptions, the period of the discontinuous reception is reduced by a first step length.

It can be understood that, since the terminal device receives the signal scheduled by the network device, the network device can know whether the terminal device needs to receive the signal each time the terminal device is in the activation period of discontinuous reception.

Based on the above 1 possible implementation manner, before the network device decreases the discontinuous reception period by the first step, it may further count a first count, where the first count is a continuous number of times that the terminal device needs to receive signals in each activation period of the discontinuous reception, and the network device determines that the first count is equal to M.

In the embodiment of the present application, how the network device counts the first count is not limited, and the network device may also count the first count through the counter 1 as in the example in fig. 6, and specifically, how to count may be described in fig. 6, which is similar to a method for counting the first count by the terminal device, and details are not described here again. By the method, both the terminal device and the network device can count the first count through the counter 1, and the terminal device and the network device can synchronously reduce the discontinuous reception period by the first step length when the first count is determined to be equal to M. Therefore, as long as the network device configures the first discontinuous reception configuration parameter for the terminal device at the initial time, and subsequently, the terminal device and the network device do not need signaling interaction, the terminal device and the network device can synchronously adjust the discontinuous reception period.

In a 2 nd 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 may adjust the discontinuous reception period in the following manner: and when the network equipment determines that the terminal equipment does not need to receive signals in the activation periods of continuous N discontinuous receptions, the network equipment increases the discontinuous reception period by a second step length.

Based on the above 2 possible implementation manner, before the network device increases the discontinuous reception period by the second step length, the network device may further count a second count, and determine that the second count is equal to N.

How to count the second count by the network device is not limited in the embodiment of the present application, and the network device may also count the second count by using the counter 2 as in the example in fig. 7, and specifically, how to count may be described in fig. 7, which is similar to the method for counting the second count by the terminal device, and details are not described here again. By the method, both the terminal device and the network device can count the second count through the counter 2, and the terminal device and the network device can synchronously increase the discontinuous reception period by the second step length when the second count is determined to be equal to N. Therefore, as long as the network device configures the first discontinuous reception configuration parameter for the terminal device at the initial time, and subsequently, the terminal device and the network device do not need signaling interaction, the terminal device and the network device can synchronously adjust the discontinuous reception period.

In a possible implementation manner of fig. 3, the first discontinuous reception configuration parameter includes an adjustment step size, M, and N, where the adjustment step size includes a first step size and a second step size. Based on this implementation, the network device may adjust the discontinuous reception period in the following manner: the network equipment reduces the discontinuous reception period by a first step length when determining that the terminal equipment needs to receive signals in the activation periods of continuous M discontinuous reception; and when the network equipment determines that the terminal equipment does not need to receive signals in the activation periods of continuous N discontinuous receptions, the network equipment increases the discontinuous reception period by a second step length. It should be noted that, in this implementation manner, if the first step size and the second step size are the same, the first drx configuration parameter may only include one adjustment step size of the first step size or the second step size, and if the first step size and the second step size are different, the first drx configuration parameter may include two step sizes of the first step size and the second step size.

Based on the above possible implementation manner of fig. 3, before the network device decreases the discontinuous reception period by the first step, it may also count a first count, and the network device determines that the first count is equal to M; before the network device increases the discontinuous reception period by the second step length, the network device may also count a second count, and determine that the second count is equal to N.

In this embodiment of the application, like in the example of fig. 8, the network device may also count the first count through the counter 1 and count the second count through the counter 2, and how to count the first count may be described with reference to fig. 8, which is not described herein again. According to the method, both the terminal equipment and the network equipment can count a first count through the counter 1, the terminal equipment and the network equipment can synchronously reduce the discontinuous reception period by a first step length when the first count is determined to be equal to M, and can count a second count through the counter 2, the terminal equipment and the network equipment can synchronously increase the discontinuous reception period by a second step length when the second count is determined to be equal to N, so that the terminal equipment and the network equipment can synchronously adjust the discontinuous reception period without signaling interaction as long as the network equipment configures the first discontinuous reception configuration parameter for the terminal equipment at the initial moment, and subsequently, the terminal equipment and the network equipment do not need signaling interaction.

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

By the method provided by the application, the network equipment can realize the self-adaptive adjustment of the discontinuous reception cycle only by configuring the discontinuous reception configuration parameters for the terminal equipment once, no additional signaling interaction is needed between the terminal equipment and the network equipment, and the signaling overhead can be saved.

In some possible scenarios, when the network device determines that the signal transmission to the terminal device fails, there may be a case where the terminal device adjusts the discontinuous reception period, but the network device does not adjust the discontinuous reception period, which may cause non-uniformity of DRX configuration between the terminal device and the network device, and further may cause errors in subsequent data transmission, thereby affecting transmission efficiency. Based on this, in this embodiment of the application, when the network device determines that the first condition is satisfied, the network device may further send the reconfigured second drx configuration parameter to the terminal device, the terminal device may receive the second drx configuration parameter from the network device, and after receiving the second drx configuration parameter, the terminal device may further update the first drx configuration parameter by using the second drx configuration parameter. Therefore, the DRX configuration parameters between the terminal equipment and the network equipment can be ensured to be consistent, and the condition that the discontinuous reception configuration parameters between the terminal equipment and the network equipment are not aligned can be avoided.

Wherein the first condition includes, but is not limited to, at least one of:

item 1: the network device determines that the signaling to the terminal device failed.

Illustratively, the network device may determine whether a data packet is lost through an Acknowledgement (ACK) or a Negative Acknowledgement (NACK) fed back by the terminal device, and when the data packet is lost, the network device may determine that sending a signal to the terminal device fails, and at this time, the network device may send the reconfigured second discontinuous reception configuration parameter to the terminal device, so as to ensure that the discontinuous reception configuration parameters between the network device and the terminal device may be aligned.

Illustratively, the network device may also determine that the signal transmission to the terminal device fails through a notification message of the terminal device. For example, assuming that the network device configures a DAI and a T-DAI for the terminal device, the terminal device may determine whether a data packet is lost through the DAI and the T-DAI, and if the data packet is lost, the network device may be notified through a notification message, and the network device may determine that the signal transmission to the terminal device is failed according to the notification message.

Item 2: the time for transmitting signals between the network device and the terminal device reaches a first threshold. Therefore, when the time for transmitting the signal reaches the first threshold value, the network equipment and the terminal equipment can be agreed to align the configuration parameters once discontinuously received, the DRX configuration between the terminal equipment and the network equipment can be ensured to be consistent, and communication errors are avoided.

The discontinuous reception configuration method described above is used to configure discontinuous reception to adapt to a real-time changing service state of a terminal device. In addition to this technical problem, there is another technical problem in the prior art. In the prior art, a network device configures a uniform drx-inactivity timer for a terminal device, the uniform drx-inactivity timer cannot meet service requirements of all terminal devices, and how to configure the drx-inactivity timer to meet the service requirements of different terminal devices is another technical problem to be solved.

The embodiment of the application provides another discontinuous reception configuration method and device, which are used for flexibly configuring drx-inactivity timers so as to meet service requirements of different terminal devices. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

Fig. 9 is a flowchart of another discontinuous reception configuration method according to an embodiment of the present application. The method comprises the following steps:

step 501: the terminal equipment measures to obtain a first CQI.

Step 502: and the terminal equipment determines a first drx-inactivity timer corresponding to the first CQI according to the first CQI and the first corresponding relation. Wherein the first corresponding relationship comprises a one-to-one corresponding relationship between at least one CQI and at least one drx-inactivity timer. It should be noted that the corresponding relationship in the present application may also be understood as a mapping relationship, and the corresponding relationship and the mapping relationship may be described interchangeably hereinafter.

In the embodiment of the present application, the size of the CQI in the first mapping is inversely related to the size of the drx-inactivity timer, which may also be understood as being inversely proportional, that is, the larger the CQI value in the first mapping is, the smaller the drx-inactivity timer corresponding to the CQI is.

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

In the embodiment of the application, a drx-inactivity timer is configured according to the size of the CQI. Because terminal equipment with low CQI (for example, terminal equipment at the edge of a cell) needs higher possibility of data retransmission, larger transmission time and transmission times are needed, the method provided by the application configures a larger drx-inactivity timer for the part of terminal equipment with low CQI to increase the transmission time of the part of terminal equipment with low CQI, so that the transmission times can be increased, and the method configures a higher drx-inactivity timer for the terminal equipment with low CQI to improve the transmission efficiency. On the contrary, the Modulation and Coding Scheme (MCS) of the terminal device with high CQI is also high, the coding efficiency is higher, which means that the number of bits that can be transmitted at one time is more in scheduling, and for the part of the terminal devices with high CQI, the data transmission can be completed with less transmission time and transmission times.

In this embodiment, the first corresponding relationship may be presented in a table form, see table 1, which is a first corresponding relationship provided in the embodiments of the present application, where the first corresponding relationship in table 1 is merely an illustrative example, and the first corresponding relationship in the present application is not limited thereto.

TABLE 1

As shown in table 1, the first corresponding relationship shown in table 1 includes 10 corresponding relationships, and the first corresponding relationship 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, and 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, and 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 timer is 40, and 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 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.

The method of fig. 9 will be described with reference to the first correspondence relationship shown in table 1 as an example. Assuming that the first CQI measured by the terminal device in step 501 is 6, the terminal device may determine, according to the first corresponding relationship in table 1, that the first drx-inactivity timer corresponding to the first CQI is 30.

Since CQI is an instantaneous variable and is greatly affected by a channel in a time-varying scenario, CQI is an average value of CQI over a period of time in the time-varying scenario.

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: and the network equipment determines a first drx-inactivity timer corresponding to the first CQI according to the first CQI and the first corresponding relation.

The sequence of the steps 502 and 503 is not limited in this embodiment. For example, in one possible implementation, step 502 is performed first, and then step 503 is performed. In another possible implementation, step 503 is performed first, and then step 502 is performed. In yet another possible implementation, step 502 and step 503 are performed simultaneously.

In addition to the above two technical problems, another technical problem exists in the prior art for the configuration of discontinuous reception. In the prior art, terminal devices in a DRX sleep period may have sudden changes such as rotation, translation, or occlusion, which may cause that, after the part of terminal devices enters a DRX active period from the DRX sleep period, beams of the part of terminal devices may not be aligned with beams of network devices, which may further cause that, the part of terminal devices may not effectively monitor a 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 to be solved.

The embodiments of the present application provide a further method and apparatus for configuring discontinuous reception, by which a terminal device wakes up in the last short period of a sleep period, and performs beam selection, so as to align a beam of the terminal device with a beam of a network device, thereby ensuring that the beam of the terminal device is aligned with the beam of the network device after the terminal device enters a DRX activation period. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

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

Fig. 10 is a flowchart of another discontinuous reception configuration method according to an embodiment of the present application. The method comprises the following steps:

step 601: the terminal device determines a first speed level, and the first speed level represents the moving or rotating speed of the terminal device.

In the embodiment of the application, the terminal device may detect the moving speed through the sensor accelerometer, may detect the rotating speed through the gyroscope, and after detecting the moving speed and/or the rotating speed, may further determine the first speed level according to the moving speed and/or the rotating speed. For example, the terminal device may determine a speed class corresponding to the measured moving speed and/or rotating speed according to the correspondence between the moving speed and/or rotating speed and the speed class.

In a possible implementation manner, the terminal device may determine a moving speed or a rotating speed, and send the moving speed or the rotating speed to the network device, and the network device determines what speed class the moving speed or the rotating speed belongs to according to a preset rule. For example, assuming that the terminal device determines that the moving speed is 9 (for illustration only) and then transmits the moving speed to the network device, the network device may determine that the speed class corresponding to the moving speed 9 is high according to the pre-stored correspondence between the moving speed and the speed class, as shown in table 2.

TABLE 2

Speed of movement	1-3	4-6	7-9
				Speed rating	Low speed	Medium speed	High speed

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

In this embodiment of the present application, the terminal device may send the first speed class to the network device through an existing UE association information message, and certainly, may also send the first speed class to the network device through a new message, which is not limited in this application. When the terminal device sends the first speed class through the UE association information message, a field, i.e., the speed class of the terminal device (e.g., UE-speed), needs to be newly added to the existing UE association information message, and specifically, the field may correspond to multiple classes, e.g., low speed, high speed, medium speed, and static.

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 does not occur, and it is not necessary to perform beam alignment by using the method of the present application.

Step 603: the network device determines a first pre-wake-up-window (pre-wake-up-window) corresponding to the first speed level and the first beam number according to the first speed level, the first beam number of the terminal device and a second corresponding relation, wherein the second corresponding relation comprises a one-to-one corresponding relation of at least one speed level, at least one beam number and at least one pre-prepare-time, the pre-prepare-time is a period of time before an activation period of discontinuous reception, and the terminal device can wake up from a sleep period to perform beam selection in the pre-prepare-time.

In the embodiment of the present application, the pre-preparation time is a period of time before an active period of discontinuous reception, and may also be understood as the pre-preparation time is a period of time included in a sleep period of discontinuous reception, referring to fig. 11, another possible C-DRX mode flowchart is provided for the present application, the C-DRX mode in fig. 11 is a mode in which the pre-preparation time is configured by using the method shown in fig. 10 of the present application, and as can be seen from fig. 11, in a C-DRX state, a period of time before the active period, that is, a last period of time included in the sleep period, is the pre-preparation time.

In the embodiment of the present application, the magnitude of the number of beams in the second corresponding relationship is positively correlated with the length of the pre-preparation time, which can also be understood as being proportional, that is, the larger the number of beams in the second corresponding relationship is, the longer the pre-preparation time corresponding to the number of beams is. In addition, the speed magnitude of the speed level representation in the second correspondence relationship is positively correlated with the length of the preliminary preparation time, and may also be understood as being proportional, that is, the greater the speed of the speed level representation in the second correspondence relationship, the longer the preliminary preparation time corresponding to the speed level.

Illustratively, the second correspondence may be configured through high layer signaling or predefined.

In this embodiment, the second corresponding relationship may be presented in a form of a table, see table 3, which is a second corresponding relationship provided in the embodiment of the present application, where the second corresponding relationship in table 3 is merely an illustration, and the second corresponding relationship in the present application is not limited thereto.

TABLE 3

As shown in table 3, the second corresponding relationship shown in table 3 includes 9 corresponding relationships, and the first corresponding relationship is: when the number of beams of the terminal device is less than 10 and the speed level is low speed, the corresponding pre-preparation time is the last 1/6 time of the sleep period, and the second corresponding relation is as follows: when the number of beams of the terminal device is less than 10 and the speed level is medium, the corresponding pre-preparation time is the last 1/5 times of the sleep period, and the third correspondence is as follows: when the number of beams of the terminal device is less than 10 and the speed level is high, the corresponding pre-preparation time is the last 1/4 times of the sleep period, and the fourth 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 low speed, the corresponding pre-preparation time is the last 1/5 time of the sleep period, and the fifth corresponding relation is as follows: 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 medium speed, the corresponding pre-preparation time is the last 1/4 time of the sleep period, and the sixth correspondence relationship is: when the number of beams of the terminal equipment is more 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 the last 1/3 time of the sleep period, and the seventh corresponding relation is as follows: when the number of beams of the terminal device is greater than 20 and the speed level is low speed, the corresponding pre-preparation time is the last 1/4 times of the sleep period, and the eighth correspondence is: when the number of beams of the terminal device is greater than 20 and the speed level is medium, the corresponding pre-preparation time is the last 1/3 times of the sleep period, and the ninth correspondence relationship is: when the number of beams of the terminal device is greater than 20 and the speed level is high, the corresponding pre-preparation time is the last 1/2 times of the sleep period.

The method of fig. 10 will be described with reference to the second correspondence relationship shown in table 3 as an example. Assuming that the first speed level determined by the terminal device in step 601 is low speed and the beam of the terminal device is 6, the network device may determine, according to the first speed level, the first number of beams of the terminal device and the second corresponding relationship, that the first preparation time corresponding to the first speed level and the first number of beams is the last 1/6 time of the sleep period in step 603.

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

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

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

In the embodiment of the present application, for beam selection performed by the terminal device, reference may be made to relevant descriptions in the above part of term explanation 7), which is not described herein again. The beam selection performed by the terminal device may include beam determination, beam measurement, beam scanning, and beam reporting, and finally the reselected beam is aligned with the beam of the network device.

Based on the same inventive concept, the embodiment of the present application further provides a terminal device, which may have a structure as shown in fig. 12 and has a behavior function of the terminal device in the above method embodiment. As shown in fig. 12, the terminal device 1200 may include a transceiver unit 1201 and a processing unit 1202, where the transceiver unit 1201 may be configured to receive a first drx configuration parameter from a network device, and the processing unit 1202 may be configured to adjust a period of drx according to the first drx configuration parameter. Alternatively, the processing unit 1202 may be configured to measure a first CQI, and may also be configured to determine a first drx-inactivity timer corresponding to the first CQI according to the first CQI and a first corresponding relationship, and the transceiving unit 1201 may be configured to send the first CQI to a network device. Alternatively, the processing unit 1202 may be configured to determine a first speed level, the transceiving unit 1201 may be configured to transmit the first speed level to a network device, the transceiving unit 1201 may be further configured to receive a first pre-preparation time from the network device, and the processing unit 1202 may be further configured to perform beam selection according to the first pre-preparation time. In an implementation, the terminal device 1200 may further have a storage unit 1203, and the storage unit 1203 may be coupled with the processing unit 1202 for storing programs, instructions needed for the processing unit 1202 to perform the functions.

The first discontinuous reception configuration parameter comprises an adjustment step size, and the first discontinuous reception configuration parameter comprises M and/or N, wherein the adjustment step size is used for adjusting a discontinuous reception period, M and N are positive integers greater than or equal to 2, M is at each of the continuous times of signals which need to be received in an activation period of discontinuous reception, and N is at each of the continuous times of signals which do not need to be received in the activation period of discontinuous reception.

Based on this design, the processing unit 1202 is specifically configured to: and when determining that the activation periods of the M discontinuous receptions need to receive signals continuously, reducing the period of the discontinuous reception by the first step size.
