Due to the limited transmission power of the satellite payload of the network device and the limited bandwidth of the feeder link, in order to meet the NR NTN downlink coverage enhancement requirement, a limited number of beams need to be activated simultaneously.

[0365] FIG. 1 is a schematic diagram of an architecture of a communication system provided by an embodiment of the present application. Referring to FIG. 1, the communication system 100 includes a terminal device 101 (e.g., a UE) and a network device 102 (e.g., a base station), and the terminal device 101 and the network device 102 have a service link therebetween.

However, in the process that the network device communicates with the terminal device by using the hop-beam manner, in order to ensure that the terminal device communicates with the network device in time within the beam coverage range, the terminal device needs to continuously perform measurement, monitoring or access initiation and the like, which leads to resource waste of the terminal device and large power consumption loss of the terminal device.

[0370] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0371] FIG. 2 is a flowchart of a control method according to an embodiment of the present application. The execution subject of the control method according to the embodiment of the present application is a terminal device. It should be understood that the control method can be executed alone, or in combination with any of the embodiments of the present application or possible implementation manners of the embodiments, or in combination with any of the technical solutions in the related art.

[0372] Referring to FIG. 2, the control method includes the following steps.

[0373] S201, determining a beam state of a beam.

[0374] The beam can be any of the following: a beam selected by the terminal device, a beam in which the terminal device receives a signal, or a beam in which the terminal device is located.

[0375] The number of beams can be one or more.

[0376] In some embodiments, the beam can be a satellite beam, a synchronization block (Synchronization Signal and PBCH block, SSB) beam, or a channel state information-reference signal (Channel State information-Reference Signal, CSI-RS) beam.

[0377] The network device can send a signal to the terminal device through each of a plurality of transmission beams, and the terminal device can select to receive a signal of one or more transmission beams from the plurality of transmission beams, which can be referred to as a "beam selected by the terminal device", a "beam in which the terminal device receives a signal", or a "beam in which the terminal device is located".

[0378] The terminal device can receive a signal sent by the network device through a transmission beam through one or more reception beams, which can be referred to as a "beam selected by the terminal device", a "beam in which the terminal device receives a signal", or a "beam in which the terminal device is located".

[0379] In some embodiments, the beam state can be any of the following: a first beam state, a second beam state, and a third beam state, wherein:

[0380] The first beam state can be used to indicate that the beam is in a closed state. When the beam is in the first beam state, the coverage area of the beam has no satellite service, and the network device will not be able to provide signal service for the terminal device through the beam.

[0381] The second beam state can be used to indicate that the beam only has common messages. When the beam is in the second beam state, the beam has no active user, and the network device can send common messages to the terminal device through the beam.

[0382] In some embodiments, the common messages can be acquired by any terminal device in the coverage area of the beam, and the common messages can include necessary information for cell discovery and initial access (initiating an RRC connection establishment process and initiating an RRC connection recovery process) of the terminal device. For example, the common messages can include system broadcast messages and emergency notifications, etc., wherein the system broadcast messages can include network identification, time synchronization information, system configuration parameters, etc., and the emergency notifications can include natural disaster warnings or public safety alerts, etc.

[0383] The third beam state can be used to indicate that the beam is in an active traffic state. When the beam is in the third beam state, the beam has one or more active users, and the network device can send any message to the terminal device through the beam, or receive any message sent by the terminal device through the beam.

[0384] In some embodiments, the any message can include necessary information for cell discovery and initial access (initiating an RRC connection establishment process and initiating an RRC connection recovery process) of the terminal device, and the any message can also include uplink signaling, downlink signaling, data, etc.

[0385] In some embodiments, the terminal device can receive the indication information sent by the network device, but is not limited thereto, and the terminal device can also receive the indication information sent by other subjects, wherein the indication information is used to indicate the beam state.

[0386] In some embodiments, the indication information can be an air interface signaling message or downlink control information (DCI).

[0387] In some embodiments, the air interface signaling message can include a public signaling message and a dedicated signaling message, the public signaling message can be a signaling message that can be received by each terminal device, and the dedicated signaling message can be a signaling message that can be received by a specified terminal device.

[0388] It should be noted that in some embodiments, the terms "first beam state", "N1 state" or "N1 beam state" can be replaced with each other, the terms "second beam state", "N2 state" or "N2 beam state" can be replaced with each other, and the terms "third beam state", "N3 state" or "N3 beam state" can be replaced with each other.

[0389] S202, determining a first operation of the terminal device based on the beam state.

[0390] In some embodiments, the first operation can be determined according to the device state and the beam state of the terminal device.

[0391] The device state of the terminal device can be any one of the following: Radio Resource Control (RRC) idle state, RRC inactive state or RRC connected state.

[0392] The device state of the terminal device can be switched between the RRC idle state, the RRC inactive state or the RRC connected state. When the device state of the terminal device is different, the operation performed by the terminal device is different.

[0393] When the device state of the terminal device is the RRC idle state, the operation that can be performed by the terminal device includes at least one of the following: initiating an RRC connection establishment procedure, requesting system information (SI), listening to system message updates, listening to paging, serving cell measurement, neighbor cell measurement, and cell reselection.

[0394] When the device state of the terminal device is the RRC inactive state, the operation that can be performed by the terminal device includes at least one of the following: initiating an RRC connection resume procedure, performing a radio access network (RAN)-based notification area update, requesting SI, listening to system message updates, listening to paging, serving cell measurement, neighbor cell measurement, and cell reselection.

[0395] When the device state of the terminal device is the RRC connected state, the operation that can be performed by the terminal device includes at least one of the following: listening to system message updates, serving cell measurement, neighbor cell measurement, cell handover, and uplink and downlink data transmission.

[0396] It should be noted that the terms "operation", "action" and "behavior" can be replaced with each other. For example, in some embodiments, the "first operation" can also be referred to as "first action" or "first behavior".

[0397] In the embodiments of the present application, the terminal device can obtain the beam state of the beam, and determine the first operation of the terminal device according to the beam state, so as to avoid the terminal device performing some unnecessary operations in each beam state and causing the resources of the terminal device to be consumed, thereby saving the resources of the terminal device and reducing the power consumption of the terminal device.

[0398] In the case that the device state of the terminal device is unchanged, the terminal device can adjust the operation of the terminal device according to the beam state, so as to avoid the waste of the resources of the terminal device and reduce the power consumption of the terminal device. In the following, the process of adjusting the operation of the terminal device according to the beam state in each device state of the terminal device is described in detail in combination with Examples 1-1 to 1-7.

[0399] Example 1-1: If the device state of the terminal device is the RRC idle state or the RRC inactive state, and the beam state is the first beam state, the first operation of the terminal device can not include at least one of the following:

[0400] initiating an RRC connection establishment process;

[0401] initiating an RRC connection resumption process;

[0402] listening to a paging;

[0403] listening to a system message update;

[0404] performing serving cell measurement;

[0405] listening to a random access message.

[0406] The terminal device can perform the operation of initiating the RRC connection establishment process to request the network device to allocate necessary radio resources and signaling connections for the terminal device, so as to subsequently perform data transmission and communication.

[0407] After the RRC connection is in the inactive state, the terminal device can perform the operation of initiating the RRC connection resumption process to ensure that the terminal device can quickly resume the connection with the network device, so as to continue data transmission and communication.

[0408] The terminal device can perform the operation of listening to the paging to determine whether there is downlink data or signaling to be processed through the paging message sent by the network device.

[0409] The terminal device can perform the operation of listening to the system message update to listen to the system message to obtain the latest network information and configuration update, so as to ensure that the terminal device can correctly interact with the network device.

[0410] The terminal device can perform a serving cell measurement operation to measure a signal quality and other parameters of a current serving cell, and determine a connection quality of the terminal device with the current serving cell based on the signal quality and other parameters.

[0411] The random access message can include at least one of the following messages: a first random access message, a second random access message, or a third random access message.

[0412] In some embodiments, the first random access message can be a message 2 (MSG2), the second random access message can be a message 4 (MSG4), and the third random access message can be a message B (MSGB).

[0413] In some embodiments, the MSG2 can be a random access response message sent by the network device to the terminal device in a four-step random access procedure. The terminal device can determine, according to the MSG2, that the network device has confirmed a random access preamble (MSG1) sent by the terminal device in the four-step random access procedure.

[0414] In some embodiments, the MSG4 can be an RRC connection setup message sent by the network device to the terminal device in the four-step random access procedure. The terminal device can determine, according to the MSG4, that the network device has confirmed an RRC connection request sent by the terminal device and allocated necessary radio resources in the four-step random access procedure.

[0415] In some embodiments, the MSGB can be a random access response message sent by the network device to the terminal device in a two-step random access procedure. The terminal device can determine, according to the MSGB, that the network device has confirmed a random access preamble (MSGA) sent by the terminal device in the two-step random access procedure.

[0416] Example 1-2: If the device state of the terminal device is an RRC idle state or an RRC inactive state, and the beam state is the second beam state, the terminal device can further adjust the operation of the terminal device in combination with the service performed by the terminal device.

[0417] Example 1-2-1: If the service performed by the terminal device can include at least one of the following: non-urgent service, service with a priority less than a preset priority, and service with a priority less than or equal to a preset priority, the first operation of the terminal device can not include at least one of the following:

[0418] initiating an RRC connection setup procedure;

[0419] initiating an RRC connection resume procedure;

[0420] listening to a random access message.

[0421] In some embodiments, the related content of the random access message in this example can refer to the related content of the random access message in Example 1-1, which will not be repeated here.

[0422] The emergency service is a communication service provided in an emergency situation, such as an emergency call or an emergency notification.

[0423] The non-emergency service is a communication service other than the emergency service.

[0424] In some embodiments, the preset priority can be any one of the following: a priority agreed upon by a protocol, a priority configured by a network device, a priority defined by a device manufacturer providing the terminal device, or a priority customized by a user.

[0425] In some embodiments, whether the service performed by the terminal device is an emergency service and the comparison between the priority of the service performed by the terminal device and the preset priority can be identified by the device manufacturer providing the terminal device.

[0426] In the embodiments of the present application, in the first beam state and / or the second beam state, the first operation of the terminal device in the RRC idle state or the RRC inactive state can not include: listening to the random access message.

[0427] Therefore, in some embodiments, in the first beam state and / or the second beam state, the terminal device in the RRC idle state or the RRC inactive state can further perform at least one of the following operations:

[0428] Extending the value of the random access response (RAR) window, which can include: a RAR window for listening to MSG2, and / or a RAR window for listening to MSGB;

[0429] Extending the value of the contention resolution timer duration.

[0430] In some embodiments, the value of the RAR window for listening to MSG2 can be any one of the following:

[0431] The sum of the value of the RAR window for listening to MSG2 configured by the network device and the duration of the first beam state in the MSG2 listening process;

[0432] The sum of the value of the RAR window for listening to MSG2 configured by the network device, the duration of the first beam state in the MSG2 listening process, and the duration of the second beam state.

[0433] There can be one or more first beam states and / or one or more second beam states in the MSG2 listening process.

[0434] Supposing that there are N first beam statuses in the monitoring MSG2 process, where N is an integer greater than or equal to 1, the duration of the first beam status in the monitoring MSG2 process = the duration of the first first beam status + the duration of the second first beam status + … + the duration of the Nth first beam status.

[0435] Supposing that there are M second beam statuses in the monitoring MSG2 process, where M is an integer greater than or equal to 1, the duration of the second beam status in the monitoring MSG2 process = the duration of the first second beam status + the duration of the second second beam status + … + the duration of the Mth second beam status.

[0436] For example, supposing that the network device configures the RAR window for monitoring MSG2 to be 10 ms, there are 2 first beam statuses and 1 second beam status in the monitoring MSG2 process, where the duration of the first first beam status is 2 ms, the duration of the second first beam status is 1 ms, and the duration of the second beam status is 5 ms. If the value of the RAR window for monitoring MSG2 is the sum of the value of the RAR window for monitoring MSG2 configured by the network device and the duration of the first beam status in the monitoring MSG2 process, the value of the RAR window for monitoring MSG2 can be 13 ms; if the value of the RAR window for monitoring MSG2 is the sum of the value of the RAR window for monitoring MSG2 configured by the network device, the duration of the first beam status in the monitoring MSG2 process, and the duration of the second beam status, the value of the RAR window for monitoring MSG2 can be 18 ms.

[0437] In some embodiments, the value of the RAR window for monitoring MSGB can be any one of the following:

[0438] the sum of the value of the RAR window for monitoring MSGB configured by the network device and the duration of the first beam status in the monitoring MSGB process;

[0439] the sum of the value of the RAR window for monitoring MSGB configured by the network device, the duration of the first beam status in the monitoring MSGB process, and the duration of the second beam status.

[0440] There can be one or more first beam statuses and / or one or more second beam statuses in the monitoring MSGB process.

[0441] It should be noted that the implementation of determining the duration of the first beam status in the monitoring MSGB process can refer to the implementation of determining the duration of the first beam status in the monitoring MSG2 process, and the implementation of determining the duration of the second beam status in the monitoring MSGB process can refer to the implementation of determining the duration of the second beam status in the monitoring MSG2 process, which will not be described herein again.

[0442] In some embodiments, the value of the contention resolution timer length is any one of the following:

[0443] The value of the contention resolution timer length configured by the network device is the sum of the length of the first beam state in the MSG4 monitoring process;

[0444] The value of the contention resolution timer length configured by the network device is the sum of the length of the first beam state and the length of the second beam state in the MSG4 monitoring process.

[0445] There can be one or more first beam states and / or one or more second beam states in the MSG4 monitoring process.

[0446] The method can guarantee that the terminal device in the RRC idle state or the RRC inactive state can monitor the following MSG2 or MSGB in time by extending the value of the RAR window; and / or, the terminal device in the RRC idle state or the RRC inactive state can monitor the MSG4 in time by extending the value of the contention resolution timer length, so as to improve the success rate of the terminal device in monitoring the above messages.

[0447] Example 1-2-2: If the service performed by the terminal device can include at least one of the following: emergency service, service with priority greater than a preset priority, service with priority greater than or equal to a preset priority, the terminal device can further determine the next beam state of the beam after determining the beam state of the beam, and determine the second operation of the terminal device according to the remaining length of the second beam state and the next beam state.

[0448] In some embodiments, in the scenario shown in example 1-2-2, the process in which the terminal device adjusts the operation of the terminal device can be as shown in the embodiment of FIG. 3:

[0449] FIG. 3 is a flowchart of a control method according to an embodiment of the present application. The embodiment of the present application relates to the execution subject of the control method, which is a terminal device. It should be understood that the control method can be executed alone, or in combination with any embodiment or possible implementation manner of the embodiments of the present application, or in combination with any technical solution in the related art.

[0450] Please refer to FIG. 3, the control method includes the following steps:

[0451] S301, obtaining indication information.

[0452] In some embodiments, the indication information can be indication information sent by a network device to a terminal device, but is not limited thereto, and the indication information can also be indication information sent by other subjects to the terminal device.

[0453] In some embodiments, the terminal device can request the network device to acquire the indication information, or the terminal device can receive the indication information sent by the network device actively.

[0454] S302, determining the beam state of the beam according to the indication information.

[0455] In some embodiments, the indication information can include the identification of the beam state of the beam existing in the target time length. The beam can exist in one beam state or multiple beam states in the target time length. When there are multiple beam states, the indication information can also be used to indicate the order, the number of occurrences and the duration of each occurrence of each beam state in the multiple beam states.

[0456] Optionally, the target time length can be a time length configured by the network device or a time length requested by the terminal device. The unit of the target time length can be any one of the following: slot, millisecond (ms), frame or sub-frame.

[0457] In some examples, the presentation form of the indication information can be in the form of a table, for example, the indication information can be as shown in Table 1:

[0458] Table 1

[0459] As shown in Table 1, the indication information can include the identification of the beam, which can be the beam index. Beam 1 exists in three beam states in 45 milliseconds, in which the first beam state occurs three times, and the second beam state and the third beam state each occur twice. The first beam state occurs for 5 milliseconds for the first time, for 2 milliseconds for the second time and for 3 milliseconds for the third time. The second beam state occurs for 10 milliseconds for the first time and for 7 milliseconds for the second time. The third beam state occurs for 13 milliseconds for the first time and for 10 milliseconds for the second time.

[0460] The network device can configure the duration of each beam state of the beam.

[0461] In some embodiments, the duration of the third beam state, and / or the duration of the second beam state, can meet the time length of at least one random access procedure of the terminal device.

[0462] S303, determining the next beam state of the beam when the beam state is the second beam state and the preset condition is met.

[0463] The preset condition can be that the device state of the terminal device is an RRC idle state or an RRC inactive state, and the service executed by the terminal device includes at least one of the following: emergency service, service with a priority greater than a preset priority, and service with a priority greater than or equal to the preset priority.

[0464] The next beam state can be the first beam state or the third beam state. For example, in Table 1, the next beam state after the first occurrence of the second beam state is the third beam state, and the next beam state after the second occurrence of the second beam state is the first beam state.

[0465] S304, determining a second operation of the terminal device according to the remaining duration of the second beam state and the next beam state.

[0466] In some embodiments, if the next beam state is the first beam state, step S304 can further include at least one of the following:

[0467] If the remaining duration of the second beam state is greater than or equal to the first threshold value, and the device state of the terminal device is an RRC idle state, the second operation includes initiating an RRC connection establishment process.

[0468] If the remaining duration of the second beam state is less than the first threshold value, and the device state of the terminal device is an RRC idle state, the second operation includes not initiating an RRC connection establishment process.

[0469] If the remaining duration of the second beam state is greater than or equal to the first threshold value, and the device state of the terminal device is an RRC inactive state, the second operation includes initiating an RRC connection recovery process.

[0470] If the remaining duration of the second beam state is less than the first threshold value, and the device state of the terminal device is an RRC inactive state, the second operation includes not initiating an RRC connection recovery process.

[0471] The first threshold value can be configured by a network device (for example, a base station), and the first threshold value can also be defined by the terminal device.

[0472] In some embodiments, the terminal device can receive the first threshold value sent by the network device.

[0473] It can be understood that, since the next beam state of the second beam state is the first beam state, the terminal device cannot perform the communication service in the first beam state. In the embodiments of the present application, if the remaining duration of the second beam state of the terminal device in the RRC idle state can at least meet the terminal device in the RRC idle state initiating 1 complete RRC connection establishment process, the terminal device in the RRC idle state can continue to perform the operation of initiating the RRC connection establishment process, so as to ensure that the RRC connection establishment process can be completely performed; otherwise, the terminal device in the RRC idle state will no longer continue to perform the operation of initiating the RRC connection establishment process within the remaining duration of the second beam state, so as to reduce the power consumption of the terminal device in the RRC idle state, and also can avoid the following situation: the terminal device in the RRC idle state successfully initiates the RRC connection establishment process within the remaining duration of the second beam state, but due to the beam state of the beam being switched from the second beam state to the first beam state at a subsequent time, the terminal device in the RRC idle state cannot normally receive the response information sent by the network device, trigger a false judgment process, etc., which is beneficial to improve user experience.

[0474] In the embodiments of the present application, if the remaining duration of the second beam state of the terminal device in the RRC inactive state can at least meet the terminal device in the RRC inactive state initiating 1 complete RRC connection recovery process, the terminal device in the RRC inactive state can continue to perform the operation of initiating the RRC connection recovery process, so as to ensure that the RRC connection recovery process can be completely performed; otherwise, the terminal device in the RRC inactive state will no longer continue to perform the operation of initiating the RRC connection recovery process within the remaining duration of the second beam state, so as to reduce the power consumption of the terminal device in the RRC inactive state, and also can avoid the following situation: the terminal device in the RRC inactive state successfully initiates the RRC connection recovery process within the remaining duration of the second beam state, but due to the beam state of the beam being switched from the second beam state to the first beam state at a subsequent time, the terminal device in the RRC inactive state cannot normally receive the response information sent by the network device, trigger a false judgment process, etc., which is beneficial to improve user experience.

[0475] In an example, assuming that the shortest duration of the terminal device in the RRC idle state initiating 1 RRC connection establishment process is a first duration, the shortest duration of the terminal device in the RRC inactive state initiating 1 RRC connection recovery process is a second duration, if the first duration is equal to the second duration, the first threshold can be greater than or equal to the first duration (or the second duration); if the first duration is greater than the second duration, the first threshold can be greater than or equal to the first duration; if the first duration is less than the second duration, the first threshold can be greater than or equal to the second duration.

[0476] In some embodiments, if the next beam state is the first beam state, step S304 can further include:

[0477] If the remaining duration of the second beam state is greater than or equal to the second threshold, the second operation includes: sending a message 3 (MSG3) to the network device; or, if the remaining duration of the second beam state is less than the second threshold, the second operation includes: not sending the MSG3 to the network device.

[0478] In some embodiments, the MSG3 can be an RRC connection request sent by the terminal device to the network device in a four-step random access process. The network device can determine whether to establish an RRC connection with the terminal device according to the MSG3.

[0479] The second threshold can be configured by the network device (e.g., a base station), and the second threshold can also be defined by the terminal device.

[0480] In an example, the second threshold can be greater than or equal to the shortest duration of sending one MSG3 by the terminal device to the network device.

[0481] Optionally, the units of the first threshold and the second threshold can be any one of the following: a slot, a millisecond (ms), a frame, or a sub-frame.

[0482] The first threshold and the second threshold can be the same, and the first threshold and the second threshold can also be different.

[0483] In some embodiments, the terminal device can receive the second threshold sent by the network device.

[0484] If the first threshold and the second threshold are the same, the first threshold (or the second threshold) satisfies the following conditions: greater than or equal to the first duration, greater than or equal to the second duration, and greater than or equal to the shortest duration of sending one MSG3 by the terminal device to the network device.

[0485] In some embodiments, if the next beam state is the third beam state, step S304 can further include at least one of the following:

[0486] If the sum of the remaining duration of the second beam state and the duration of the third beam state is greater than or equal to the first threshold, and the device state of the terminal device is an RRC idle state, the second operation includes: initiating an RRC connection establishment process;

[0487] If the sum of the remaining duration of the second beam state and the duration of the third beam state is less than the first threshold, and the device state of the terminal device is an RRC idle state, the second operation includes: not initiating the RRC connection establishment process;

[0488] If the sum of the remaining duration of the second beam state and the duration of the third beam state is greater than or equal to the first threshold value and the device state of the terminal device is the RRC inactive state, the second operation includes initiating an RRC connection resumption procedure.

[0489] If the sum of the remaining duration of the second beam state and the duration of the third beam state is less than the first threshold value and the device state of the terminal device is the RRC inactive state, the second operation includes not initiating an RRC connection resumption procedure.

[0490] It can be understood that the terminal device in the RRC idle state can initiate an RRC connection establishment procedure in both the second beam state and the third beam state, and the terminal device in the RRC inactive state can initiate an RRC connection resumption procedure in both the second beam state and the third beam state.

[0491] In the embodiments of the present application, if the sum of the remaining duration of the second beam state and the duration of the third beam state at least meets the terminal device in the RRC idle state initiating one complete RRC connection establishment procedure, the terminal device in the RRC idle state can continue to perform the operation of initiating the RRC connection establishment procedure, so as to ensure that the RRC connection establishment procedure can be completely performed; otherwise, the terminal device in the RRC idle state will no longer continue to perform the operation of initiating the RRC connection establishment procedure within the remaining duration of the second beam state and the duration of the third beam state, so as to reduce the power consumption of the terminal device in the RRC idle state.

[0492] In the embodiments of the present application, if the sum of the remaining duration of the second beam state and the duration of the third beam state at least meets the terminal device in the RRC inactive state initiating one complete RRC connection resumption procedure, the terminal device in the RRC inactive state can continue to perform the operation of initiating the RRC connection resumption procedure, so as to ensure that the RRC connection resumption procedure can be completely performed; otherwise, the terminal device in the RRC inactive state will no longer continue to perform the operation of initiating the RRC connection resumption procedure within the remaining duration of the second beam state and the duration of the third beam state, so as to reduce the power consumption of the terminal device in the RRC inactive state.

[0493] In some embodiments, if the next beam state is the third beam state, step S304 can further include at least one of the following:

[0494] If the sum of the remaining duration of the second beam state and the duration of the third beam state is greater than or equal to the second threshold value, the second operation includes sending MSG3 to the network device; or if the sum of the remaining duration of the second beam state and the duration of the third beam state is less than the second threshold value, the second operation includes not sending MSG3 to the network device.

[0495] In the embodiments of the present application, if the sum of the remaining duration of the second beam state and the duration of the third beam state can at least satisfy that the terminal device in the RRC idle state or the RRC inactive state initiates 1 MSG3, the terminal device in the RRC idle state or the RRC inactive state can continue to perform the operation of initiating the MSG3, so as to ensure that the operation of initiating the MSG3 can be correctly performed; otherwise, the terminal device in the RRC idle state or the RRC inactive state will no longer continue to perform the operation of initiating the MSG3 within the remaining duration of the second beam state and the duration of the third beam state, so as to reduce the power consumption of the terminal device in the RRC idle state or the RRC inactive state.

[0496] Example 1-3: If the device state of the terminal device is the RRC idle state or the RRC inactive state, and the beam state is the third beam state, the terminal device can further adjust the operation of the terminal device in combination with the service performed by the terminal device.

[0497] Example 1-3-1: If the service performed by the terminal device can include at least one of the following: non-urgent service, service with a priority less than a preset priority, service with a priority less than or equal to a preset priority, the terminal device can adjust the operation of the terminal device based on the duration of the third beam state.

[0498] If the duration of the third beam state is greater than or equal to the first threshold, and the device state of the terminal device is the RRC idle state, the first operation includes initiating an RRC connection establishment process.

[0499] If the duration of the third beam state is less than the first threshold, and the device state of the terminal device is the RRC idle state, the first operation includes not initiating an RRC connection establishment process.

[0500] If the duration of the third beam state is greater than or equal to the first threshold, and the device state of the terminal device is the RRC inactive state, the first operation includes initiating an RRC connection recovery process.

[0501] If the duration of the third beam state is less than the first threshold, and the device state of the terminal device is the RRC inactive state, the first operation includes not initiating an RRC connection recovery process.

[0502] It can be understood that in the third beam state, the terminal device in the RRC idle state can normally initiate the RRC connection establishment process, and the terminal device in the RRC inactive state can also normally initiate the RRC connection resumption process. In the embodiments of the present application, when the duration of the third beam state does not meet the condition that the terminal device in the RRC idle state initiates the RRC connection establishment process at least once, the terminal device in the RRC idle state can be prevented from continuing to initiate the RRC connection establishment process within the duration of the third beam state, so as to reduce the resource waste of the terminal device in the RRC idle state and reduce the power consumption of the terminal device in the RRC idle state. When the duration of the third beam state does not meet the condition that the terminal device in the RRC inactive state initiates the RRC connection resumption process at least once, the terminal device in the RRC inactive state can be prevented from continuing to initiate the RRC connection resumption process within the duration of the third beam state, so as to reduce the resource waste of the terminal device in the RRC inactive state and reduce the power consumption of the terminal device in the RRC inactive state.

[0503] In some embodiments, when the device state of the terminal device is the RRC idle state or the RRC inactive state, if the duration of the third beam state is greater than or equal to the second threshold, the first operation includes: sending MSG3 to the network device; or if the duration of the third beam state is less than the second threshold, the first operation does not include: sending MSG3 to the network device.

[0504] It can be understood that in the third beam state, the terminal device in the RRC idle state or the RRC inactive state can normally send MSG3 to the network device. In the embodiments of the present application, when the duration of the third beam state does not meet the condition that the terminal device in the RRC idle state or the RRC inactive state sends MSG3 to the network device at least once, the terminal device in the RRC idle state or the RRC inactive state can be prevented from continuing to send MSG3 to the network device within the duration of the third beam state, so as to reduce the resource waste of the terminal device in the RRC idle state or the RRC inactive state and reduce the power consumption of the terminal device in the RRC idle state or the RRC inactive state.

[0505] Example 1-3-2: When the service performed by the terminal device can include at least one of the following: emergency service, service with priority greater than a preset priority, service with priority greater than or equal to a preset priority, the terminal device can further determine the next beam state of the beam after determining the beam state of the beam, and determine the third operation of the terminal device according to the remaining duration of the third beam state and the next beam state.

[0506] In some embodiments, in the scenario shown in example 1-3-2, the process in which the terminal device adjusts the operation of the terminal device can be as shown in the embodiment of FIG. 4:

[0507] FIG. 4 is a third flow diagram of a control method according to an embodiment of the present application. The execution subject of the control method according to the embodiment of the present application is a terminal device. It should be understood that the control method can be executed alone, or in combination with any of the embodiments or possible implementation manners of the embodiments of the present application, or in combination with any of the related technologies.

[0508] Referring to FIG. 4, the control method comprises the following steps.

[0509] S401: acquiring indication information.

[0510] S402: determining a beam state of a beam according to the indication information.

[0511] It should be noted that the specific execution process of steps S401 and S402 can refer to the specific execution process of steps S301 and S302, which will not be described here.

[0512] S403: determining a next beam state of the beam in a case where the beam state is a third beam state and a preset condition is met.

[0513] The preset condition can be that the device state of the terminal device is an RRC idle state or an RRC inactive state, and the service executed by the terminal device comprises at least one of the following: emergency service, service with a priority greater than a preset priority, and service with a priority greater than or equal to a preset priority.

[0514] The next beam state can be the first beam state or the second beam state. For example, in Table 1, the next beam state after the first occurrence of the third beam state is the second beam state, and the next beam state after the second occurrence of the third beam state is the first beam state.

[0515] S404: determining a third operation of the terminal device according to the remaining time length of the third beam state and the next beam state.

[0516] In some embodiments, if the next beam state is the first beam state, step S404 can further comprise at least one of the following:

[0517] If the remaining time length of the third beam state is greater than or equal to a first threshold value and the device state of the terminal device is an RRC idle state, the third operation comprises initiating an RRC connection establishment process.

[0518] If the remaining time length of the third beam state is less than the first threshold value and the device state of the terminal device is an RRC idle state, the third operation comprises not initiating an RRC connection establishment process.

[0519] If the remaining time length of the third beam state is greater than or equal to the first threshold value and the device state of the terminal device is the RRC inactive state, the third operation includes initiating an RRC connection recovery procedure.

[0520] If the remaining time length of the third beam state is less than the first threshold value and the device state of the terminal device is the RRC inactive state, the third operation includes not initiating the RRC connection recovery procedure.

[0521] In some embodiments, if the next beam state is the first beam state, step S404 can further include:

[0522] If the remaining time length of the third beam state is greater than or equal to the second threshold value, the third operation includes sending an MSG3 to the network device, or if the remaining time length of the third beam state is less than the second threshold value, the third operation includes not sending the MSG3 to the network device.

[0523] It can be understood that, since the next beam state of the third beam state is the first beam state, the terminal device cannot perform a communication service in the first beam state. In the embodiments of the present application, when the remaining time length of the third beam state does not satisfy that the terminal device in the RRC idle state initiates the RRC connection establishment procedure at least once, the terminal device in the RRC idle state can be prevented from continuing to initiate the RRC connection establishment procedure within the remaining time length of the third beam state, so as to reduce resource waste of the terminal device in the RRC idle state and reduce power consumption of the terminal device in the RRC idle state. When the remaining time length of the third beam state does not satisfy that the terminal device in the RRC inactive state initiates the RRC connection recovery procedure at least once, the terminal device in the RRC inactive state can be prevented from continuing to initiate the RRC connection recovery procedure within the remaining time length of the third beam state, so as to reduce resource waste of the terminal device in the RRC inactive state and reduce power consumption of the terminal device in the RRC inactive state. When the remaining time length of the third beam state does not satisfy that the terminal device in the RRC idle state or the RRC inactive state sends the MSG3 to the network device at least once, the terminal device in the RRC idle state or the RRC inactive state can be prevented from continuing to send the MSG3 to the network device within the remaining time length of the third beam state, so as to reduce resource waste of the terminal device in the RRC idle state or the RRC inactive state and reduce power consumption of the terminal device in the RRC idle state or the RRC inactive state.

[0524] In some embodiments, if the next beam state is the second beam state, step S404 can further include at least one of the following:

[0525] If the sum of the remaining time length of the third beam state and the duration of the second beam state is greater than or equal to the first threshold value and the device state of the terminal device is the RRC idle state, the third operation includes initiating an RRC connection establishment procedure.

[0526] if the sum of the remaining duration of the third beam state and the duration of the second beam state is less than the first threshold value, and the device state of the terminal device is the RRC idle state, the third operation does not include initiating an RRC connection establishment procedure;

[0527] if the sum of the remaining duration of the third beam state and the duration of the second beam state is greater than or equal to the first threshold value, and the device state of the terminal device is the RRC inactive state, the third operation includes initiating an RRC connection resume procedure.

[0528] if the sum of the remaining duration of the third beam state and the duration of the second beam state is less than the first threshold value, and the device state of the terminal device is the RRC inactive state, the third operation does not include initiating an RRC connection resume procedure.

[0529] In some embodiments, if the next beam state is the second beam state, step S404 can further include:

[0530] if the sum of the remaining duration of the third beam state and the duration of the second beam state is greater than or equal to the second threshold value, the third operation includes sending an MSG3 to the network device; or if the sum of the remaining duration of the third beam state and the duration of the second beam state is less than the second threshold value, the third operation includes not sending an MSG3 to the network device.

[0531] In the embodiments of the present application, when the sum of the remaining duration of the third beam state and the duration of the second beam state does not satisfy that the terminal device in the RRC idle state initiates at least one RRC connection establishment procedure, the terminal device in the RRC idle state can be prevented from continuing to initiate the RRC connection establishment procedure within the remaining duration of the third beam state, so as to reduce the resource waste of the terminal device in the RRC idle state and reduce the power consumption of the terminal device in the RRC idle state. When the sum of the remaining duration of the third beam state and the duration of the second beam state does not satisfy that the terminal device in the RRC inactive state initiates at least one RRC connection resume procedure, the terminal device in the RRC inactive state can be prevented from continuing to initiate the RRC connection resume procedure within the remaining duration of the third beam state, so as to reduce the resource waste of the terminal device in the RRC inactive state and reduce the power consumption of the terminal device in the RRC inactive state. When the sum of the remaining duration of the third beam state and the duration of the second beam state does not satisfy that the terminal device in the RRC idle state or the RRC inactive state sends at least one MSG3 to the network device, the terminal device in the RRC idle state or the RRC inactive state can be prevented from continuing to send the MSG3 to the network device within the sum of the remaining duration of the third beam state and the duration of the second beam state, so as to reduce the resource waste of the terminal device in the RRC idle state or the RRC inactive state and reduce the power consumption of the terminal device in the RRC idle state or the RRC inactive state.

[0532] It should be noted that the related content of the terms "first threshold value" and "second threshold value" in this embodiment can refer to the related content of the terms "first threshold value" and "second threshold value" in the embodiment of FIG. 3, which will not be repeated here.

[0533] Example 1-4: If the device state of the terminal device is the RRC connected state, and the beam state is the first beam state, the first operation of the terminal device can not include at least one of the following:

[0534] initiating an RRC connection reestablishment procedure;

[0535] performing serving cell measurement;

[0536] listening to system message update;

[0537] performing out-of-sync detection;

[0538] listening to a physical downlink control channel (PDCCH);

[0539] listening to a semi-persistent scheduling (SPS) occasion;

[0540] sending new data or retransmitting data on a configured grant (CG) resource;

[0541] sending a scheduling request (SR);

[0542] increasing the number of SRs;

[0543] starting an SR timer;

[0544] sending a channel state information (CSI) report.

[0545] In some embodiments, the CSI report can include a periodic CSI report and a semi-static CSI report. In the first beam state, the first operation of the terminal device in the RRC connected state can not include: sending a periodic CSI report, and / or sending a semi-static CSI report.

[0546] In some embodiments, when the terminal device detects that the connection quality with the current serving cell is degraded or lost, the terminal device can initiate an RRC connection reestablishment procedure to the network device.

[0547] The terminal device can determine whether the terminal device is out of synchronization with the network device by performing out-of-sync detection.

[0548] The terminal device can listen to the SPS moment to ensure that the terminal device can send or receive data at the correct time, thereby improving resource utilization efficiency.

[0549] The CG resource is a resource pre-allocated by the network device to the terminal device for data transmission. The terminal device can send new data or retransmit unsuccessfully transmitted data before to improve the reliability and efficiency of data transmission.

[0550] When the terminal device has uplink data to send but has no available uplink resource, the terminal device can send an SR to request the network device to allocate uplink resources. If the terminal device does not obtain the resources allocated by the network device immediately after sending the SR, the terminal device can increase the number of SRs and resend the SR until the terminal device obtains the resources or the number of SRs sent by the terminal device reaches the maximum retry number.

[0551] The SR timer can be used to control the sending frequency of the SR of the terminal device. Starting the SR timer can avoid the terminal device from frequently sending SRs and reduce signaling overhead.

[0552] The CSI report can include the measurement result of the terminal device on the current channel quality. The terminal device can send the CSI report to the network device, so that the network device can optimize the resource allocation and scheduling of the terminal device according to the CSI report, thereby improving the communication efficiency and quality.

[0553] It can be understood that in the first beam state, the network device will not be able to provide communication services for the terminal device. If the terminal device in the RRC connected state continues to perform service cell measurement, listening operation (including system message update, PDCCH, CSI moment), out-of-synchronization detection and other operations, it may cause the terminal device to consume the power of the terminal device due to invalid measurement, listening or detection, and may cause the terminal device to misjudge cell loss; if the terminal device in the RRC connected state continues to perform the RRC connection reestablishment process, sends new data or retransmits data on the CG resource, sends the SR, increases the number of SRs, starts the SR timer, and sends the CSI report, since the network device cannot normally receive the request of the terminal device, the terminal device may appear repeated retries, thereby consuming terminal resources and easily misjudging triggering an abnormal process, causing business anomalies, and poor user experience. Therefore, in the first beam state, the terminal device can not perform the first operation shown in examples 1-4 to reduce the power consumption of the terminal device in the first beam state and avoid business anomalies to improve user experience.

[0554] Example 1-5: If the device state of the terminal device is the RRC connected state and the beam state is the second beam state, the first operation of the terminal device has the following two cases:

[0555] Example 1-5-1: The first operation of the terminal device can include: monitoring a PDCCH scrambled by a target radio network temporary identifier (RNTI).

[0556] The target RNTI can include at least one of the following:

[0557] System Information RNTI (SI-RNTI);

[0558] Paging RNTI (P-RNTI);

[0559] Multicast Control Channel RNTI (MCCH-RNTI).

[0560] In some embodiments, the target RNTI can be used to monitor public messages. The SI-RNTI can be used to broadcast system information, the P-RNTI can be used for paging messages, and the MCCH-RNTI can be used to transmit multicast or broadcast services.

[0561] In the second beam state, the beam can provide public messages, therefore, the terminal device needs to monitor the PDCCH scrambled by the target RNTI to avoid missing the public messages sent by the network device.

[0562] Example 1-5-2: The first operation of the terminal device can not include at least one of the following:

[0563] Monitoring PDCCH scrambled by RNTI other than the target RNTI;

[0564] Sending new data or retransmitting data on CG resources;

[0565] Sending SR;

[0566] Increasing the number of SRs;

[0567] Starting an SR timer;

[0568] Sending a CSI report;

[0569] Sending a measurement report.

[0570] It can be understood that, in the second beam state, the network device can provide the terminal device with a common message service through the beam. If the terminal device in the RRC connected state continues to perform the following operations: monitoring a PDCCH scrambled by an RNTI other than the target RNTI, initiating an RRC connection process, transmitting new data or retransmitting data on a CG resource, transmitting an SR, increasing the number of SRs, starting an SR timer, and transmitting a CSI report, the network device cannot normally receive the request of the terminal device, which may cause the terminal device to repeatedly retry, consume terminal resources, and easily misjudge to trigger an abnormal process, cause service abnormity, and poor user experience. Therefore, in the second beam state, the terminal device can not perform the first operation shown in example 1-5-2, so as to reduce the power consumption of the terminal device in the first beam state, avoid service abnormity, and improve user experience.

[0571] Example 1-6: If the device state of the terminal device is the RRC connected state, and the beam state is the third beam state, the first operation of the terminal device can include: initiating a random access process through a random access channel occasion (RO).

[0572] The time domain resource of the RO is located in the duration of the third beam state.

[0573] The RO can be a specific time window in which the terminal device attempts random access using a random access channel (RACH) in the wireless communication network.

[0574] In the third beam state, the network device can provide normal communication services for the terminal device, and by controlling the time domain resource of the RO within the duration of the third beam state, the normal initiation of the random access process by the terminal device can be ensured.

[0575] Example 1-7: If the device state of the terminal device is any of the following: the RRC idle state, the RRC inactive state, or the RRC connected state, the terminal device can further perform the following operations:

[0576] Example 1-7-1: In the case where the terminal device receives public warning system (PWS) indication information, and the beam state at the current time is the second beam state or the third beam state, the terminal device can further acquire a system information block 1 (SIB1), and acquire at least one of the following information based on the SIB1: a system information block 6 (SIB6), a system information block 7 (SIB7), or a system information block 8 (SIB8).

[0577] As shown in FIG. 5, FIG. 5 is a fourth flowchart of the control method according to an embodiment of the present application. The execution subject of the control method according to the embodiment of the present application is a terminal device. It should be understood that the control method can be executed independently, or in combination with any of the embodiments or possible implementation manners of the embodiments, or in combination with any of the related technical solutions. As shown in FIG. 5, the control method can further include the following steps:

[0578] S501: acquiring SIB1.

[0579] The SIB1 can include scheduling information of SIB6, SIB7 and SIB8, so that the terminal device can read the SIB6, SIB7 and SIB8 at the correct time and frequency.

[0580] S502: acquiring at least one of SIB6, SIB7 or SIB8 according to the SIB1.

[0581] The SIB6 can be acquired according to the scheduling information of SIB6 in the SIB1, the SIB7 can be acquired according to the scheduling information of SIB7 in the SIB1, and the SIB8 can be acquired according to the scheduling information of SIB8 in the SIB1.

[0582] In the emergency scenario of receiving the PWS indication information, the terminal device does not need to judge the beam state at the subsequent time, but directly acquires the SIB1, and acquires one or more of the SIB6, SIB7 or SIB8 according to the indication in the SIB1, so as to avoid the resource consumption of the terminal device due to the judgment of the beam state at the subsequent time, save the resources of the terminal device, and reduce the power consumption.

[0583] Example 1-7-2: In the case of receiving the PWS indication information and the beam state at the current time being the second beam state or the third beam state, the operation of the terminal device can be as shown in the embodiment of FIG. 6.

[0584] FIG. 6 is a fifth flowchart of the control method according to an embodiment of the present application. The execution subject of the control method according to the embodiment of the present application is a terminal device. It should be understood that the control method can be executed independently, or in combination with any of the embodiments or possible implementation manners of the embodiments, or in combination with any of the related technical solutions. As shown in FIG. 6, the control method can further include the following steps:

[0585] S601: judging the beam state of the terminal device in a preset time period.

[0586] The starting time of the preset time period is the current time, and the interval time between the ending time of the preset time period and the starting time is equal to the preset time length.

[0587] In some embodiments, the preset time length can be any one of the following: a time length agreed by protocols, a time length predefined by a user, or a time length configured by a network.

[0588] S602, in a case where the beam state of the preset time period includes the first beam state, acquiring SIB1 within the preset time period.

[0589] S603, acquiring at least one of SIB6, SIB7, or SIB8 according to the SIB1.

[0590] In an emergency scenario where the PWS indication information is received, although the beam state of the preset time period includes the first beam state, the terminal device can not follow the first operation in the first beam state. The terminal device can immediately acquire SIB1 and acquire one or more of SIB6, SIB7, or SIB8 according to the indication in SIB1, so as to enable the terminal device to accurately grasp the beam state at each moment and avoid misoperation of the terminal device.

[0591] In some embodiments, the terminal device can interact with the network device to implement the control method provided in the embodiments of the present application. Referring to FIG. 7, FIG. 7 is an exemplary interaction diagram of a control method according to an embodiment of the present application. As shown in FIG. 7, the control method includes the following steps:

[0592] S701, the network device sends indication information to the terminal device.

[0593] In some embodiments, the indication information can be used to indicate the beam state of the beam, wherein the beam can be any one of the following: a beam selected by the terminal device, a beam receiving a signal by the terminal device, or a beam in which the terminal device is located.

[0594] The beam state can be any one of the following: a first beam state, a second beam state, or a third beam state.

[0595] It should be noted that the related content of "beam", "first beam state", "second beam state", and "third beam state" can refer to the related content in step S201, which will not be described here.

[0596] In some embodiments, the network device can indicate the beam state of the beam to the terminal device through an air interface signaling message (for example, a public signaling message or a private signaling message), or the network device can also indicate the beam state of the beam to the terminal device through DCI.

[0597] In some embodiments, after sending the indication information, if the beam state of the beam is updated, the network device can re-send the indication information to the terminal device, and the indication information can be used to indicate the updated beam state of the beam.

[0598] In some embodiments, after the beam state update of the beam, the network device can send an air interface reconfiguration message to the terminal device, where the air interface reconfiguration message is used to indicate the updated beam state of the beam.

[0599] In some embodiments, the indication information can include the duration of each beam state configured by the network device. The duration of the third beam state configured by the network device for the terminal device, and / or the duration of the second beam state configured for the terminal device, meets the duration of at least one random access procedure of the terminal device.

[0600] Case 1: The duration of the third beam state configured by the network device for the terminal device meets the duration of at least one random access procedure of the terminal device, so as to ensure that the terminal device can normally initiate a random access procedure in the third beam state.

[0601] Case 2: The duration of the second beam state configured by the network device for the terminal device meets the duration of at least one random access procedure of the terminal device, so as to ensure that the terminal device can normally initiate a random access procedure in the second beam state.

[0602] Case 3: The duration of the second beam state and the duration of the third beam state configured by the network device for the terminal device meet the duration of at least one random access procedure of the terminal device, so as to ensure that the terminal device can normally initiate a random access procedure in the second beam state and the third beam state.

[0603] S702, the terminal device determines the beam state of the beam according to the indication information.

[0604] It should be noted that the specific execution process of step S702 can refer to the specific execution process of S302, which will not be repeated here.

[0605] S703, the terminal device determines the first operation according to the device state of the terminal device and the beam state.

[0606] Next, in combination with examples 2-1 to 2-7, the process of adjusting the operation of the terminal device according to the beam state in each device state of the terminal device is described in detail.

[0607] Example 2-1: If the device state of the terminal device is RRC idle state or RRC inactive state, and the beam state is the first beam state, the first operation of the terminal device in this example can refer to the first operation of the terminal device in example 1-1, which will not be repeated here.

[0608] Example 2-2: If the device state of the terminal device is the RRC idle state or the RRC inactive state, and the beam state is the second beam state, after determining the beam state of the beam, the terminal device can further determine the next beam state of the beam, and determine the second operation of the terminal device according to the remaining time length of the second beam state and the next beam state.

[0609] Example 2-2-1: If the next beam state is the first beam state, the second operation of the terminal device can include at least one of the following cases:

[0610] If the remaining time length of the second beam state is greater than or equal to the first threshold, and the device state of the terminal device is the RRC idle state, the second operation includes initiating an RRC connection establishment procedure.

[0611] If the remaining time length of the second beam state is less than the first threshold, and the device state of the terminal device is the RRC idle state, the second operation includes not initiating the RRC connection establishment procedure.
