Description

Technical Field

[0001] This application relates to the field of mobile communications, and in particular to a DRX configuration method, apparatus, terminal and storage medium. Background Technology

[0002] Terminals often use Sidelink transmission technology to communicate with each other, and the terminal uses resources in the Sidelink to transmit data with other terminals.

[0003] When the first terminal communicates with multiple second terminals using Sidelink transmission technology, the first terminal can receive data sent by multiple second terminals. However, because different second terminals use different synchronization sources, the synchronization signals received by the first terminal from multiple second terminals are different. The time domain start position of the data transmission from the second terminals determined by the first terminal is different, resulting in the first terminal receiving different synchronization signals, which makes it impossible to execute DRX. Therefore, a DRX configuration method is urgently needed. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] First, let's explain the terms used in this application:

[0035] Sidelink:

[0036] Device-to-device communication is based on sidelink (SL) transmission technology. Unlike traditional cellular systems where data is received or transmitted through base stations, vehicle-to-everything (V2X) systems use direct terminal-to-terminal communication, resulting in higher spectral efficiency and lower transmission latency. Currently, two transmission modes are defined: Mode A and Mode B.

[0037] Mode A: The terminal's transmission resources are allocated by the base station, and the terminal transmits data on the side link according to the resources allocated by the base station. The base station can allocate resources for a single transmission or for semi-static transmission.

[0038] Mode B: The terminal selects a resource from the resource pool for data transmission.

[0039] DRX (Discontinuous Reception):

[0040] Network devices configure DRX for terminals so that terminals can monitor PDCCH discontinuously according to the configured DRX, thereby enabling terminals to monitor PDCCH at intervals and thus saving power.

[0041] For example, after the terminal determines the configured DRX, it monitors for 2 milliseconds every 10 milliseconds, or monitors for 3 milliseconds every 20 milliseconds, or receives data within a certain period of time after receiving data, and enters a sleep state if no data is received within that period of time, or uses other methods to monitor the PDCCH discontinuously.

[0042] Synchronization source:

[0043] When terminals communicate with each other, the terminal sending data synchronizes with the terminal receiving data using its own synchronization source to ensure synchronized communication. This synchronization source can also be understood as a reference point for communication between the two terminals, ensuring synchronization and preventing communication discrepancies.

[0044] The synchronization source includes synchronization with GNSS (Global Navigation Satellite System), synchronization based on base stations, or synchronization based on terminals.

[0045] The application scenarios of this application will be described below:

[0046] Figure 1A block diagram of a communication system provided in an exemplary embodiment of this application is shown. The communication system may include a first terminal 101 and a plurality of second terminals 102, each of the second terminals 102 being communicatively connected to the first terminal 101.

[0047] In this embodiment of the application, each second terminal 102 determines a resource pool for data transmission and sends data to the first terminal 101 through the resource pool. The first terminal 101 receives the data sent by each second terminal 102 in the corresponding resource pool.

[0048] Figure 2 A block diagram of a communication system provided in an exemplary embodiment of this application is shown. The communication system may include: an access network 12 and a first terminal 13 and a second terminal 14.

[0049] Access network 12 configures resources for data transmission for first terminal 13 and second terminal 14, and data transmission between first terminal 13 and second terminal 14 is carried out through the configured resources.

[0050] Access network 12 includes several network devices 120. Each network device 120 can be a base station, which is a device deployed in the access network to provide wireless communication functions for terminals. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functions may differ; for example, in LTE systems, they are called eNodeB or eNB; in 5G NR-U systems, they are called gNodeB or gNB. As communication technologies evolve, the description of "base station" may change. For convenience in this embodiment, the devices providing wireless communication functions for the first terminal 13 and the second terminal 14 are collectively referred to as access network devices.

[0051] The first terminal 13 and the second terminal 14 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile stations (MS), terminals, etc. For ease of description, the devices mentioned above are collectively referred to as terminals. The access network device 120 communicates with the first terminal 13 or the second terminal 14 through some air interface technology, such as a Uu interface.

[0052] The technical solutions of this application embodiment can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution system of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Network (WLAN). Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems.

[0053] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-everything (V2X) systems. The embodiments of this application can also be applied to these communication systems.

[0054] Figure 3This is a flowchart of a DRX configuration method provided in an embodiment of this application. See also... Figure 2 The method includes:

[0055] 310. At least one second terminal sends first data to the first terminal.

[0056] In this embodiment of the application, the first terminal and at least one second terminal can communicate with each other. When at least one second terminal needs to communicate with the first terminal, the at least one second terminal sends first data to the first terminal.

[0057] Before sending the first data to the first terminal, at least one second terminal will also send a synchronization signal to the first terminal based on the synchronization source used by the second terminal, so that the first terminal can receive the first data sent by the second terminal based on the received synchronization signal.

[0058] In some embodiments, at least one second terminal determines a resource pool for sending data and sends first data to the first terminal through the determined resource pool.

[0059] It should be noted that the embodiments in this application are only illustrated by the example of at least one second terminal sending first data to a first terminal. In another embodiment, at least one second terminal determines a resource pool in Sidelink, and then sends the first data to the first terminal through the resource pool of Sidelink.

[0060] 320. The first terminal receives the first data in the first resource pool of at least two resource pools.

[0061] In this embodiment of the application, the second terminal sends first data to the first terminal, and the first terminal has configured at least two resource pools. The first terminal receives the first data through the first resource pool among the at least two resource pools.

[0062] Each resource pool includes at least one resource, and at least two resource pools include resource pools that use the same or different synchronization sources.

[0063] In the first terminal, at least two resource pools are configured, and each resource pool uses a synchronization source. These resource pools may use the same or different synchronization sources.

[0064] 330. The first terminal executes DRX within the reference duration corresponding to the first resource pool, based on the first resource pool.

[0065] In this embodiment of the application, after receiving the first data based on the first resource pool, the first terminal determines the reference duration for executing DRX, and then executes DRX within the reference duration corresponding to the first resource pool.

[0066] When determining the reference duration corresponding to the first resource pool based on the first resource pool, the first terminal may determine one reference duration or multiple reference durations, and this application embodiment does not limit the scope of the determination.

[0067] In some embodiments, the first terminal performing DRX within a reference duration corresponding to the first resource pool includes: the first terminal continuing to receive data within a reference duration after receiving the first data; or, the first terminal stopping receiving data within a reference duration after receiving the first data, and then continuing to receive data after the reference duration has elapsed.

[0068] In some embodiments, the reference duration determined by the first terminal is indicated by a timer, so the first terminal can execute DRX according to the timer's duration.

[0069] The first terminal starts at least one timer based on the first resource pool and executes DRX within the time duration of at least one timer.

[0070] Once the timer is started, it begins to count down. The first terminal receives data or stops receiving data within the timed duration after the timer starts counting down, thus realizing the DRX of the first terminal.

[0071] The timing duration of each timer is a reference duration. The timing duration of each timer is set by the terminal, by the operator, or by other means; this embodiment of the application does not limit this.

[0072] In some embodiments, the first terminal starts a first timer based on a first resource pool.

[0073] Wherein, after the first terminal receives the first data in the first resource pool, it starts the first timer, and the first terminal executes DRX within the time period corresponding to the first timer.

[0074] The resource pool associated with the first timer will be explained below:

[0075] (1) The first timer is associated with the first resource pool.

[0076] The first timer is associated with the first resource pool. This can also be understood as the first resource pool being configured with a first timer. After the first terminal receives the first data in the first resource pool, the first timer associated with the first resource pool is started.

[0077] (2) The first timer is associated with multiple resource pools, including the first resource pool, and the multiple resource pools use the same synchronization source.

[0078] In this embodiment, the first timer is associated not only with the first resource pool, but also with other resource pools. The other resource pools associated with the first timer are resource pools that use the same synchronization source as the first resource pool. It can also be understood that multiple resource pools are controlled by the first timer. When the first timer is turned on, the first terminal performs DRX within the time duration of the first timer and within the multiple resource pools.

[0079] (3) The first timer is associated with multiple resource pools, including the first resource pool. The multiple resource pools use different synchronization sources.

[0080] In this embodiment, the first timer is associated not only with the first resource pool, but also with other resource pools. The multiple resource pools associated with the first timer use different synchronization sources. It can also be understood that multiple resource pools are controlled by the first timer. When the first timer is turned on, even if the multiple resource pools use different synchronization sources, the first terminal will still execute DRX within the time duration of the first timer and within the multiple resource pools.

[0081] In some embodiments, the first terminal starts a first timer and a second timer based on a first resource pool. The second timer is associated with a second resource pool, and the first timer is associated with the first resource pool. The synchronization source used by the second resource pool is the same as that used by the first resource pool.

[0082] After receiving the first data within the first resource pool, the first terminal starts multiple timers. These timers include a first timer and a second timer, with the first timer associated with the first resource pool and the second timer associated with the second resource pool. The synchronization source used by the first and second resource pools is the same. In other words, when the first terminal receives the first data within the first resource pool, it starts the timer associated with the resource pool using the same synchronization source. The first terminal then executes DRX within the specified duration of the started timer and the corresponding resource pool.

[0083] In this embodiment, the second resource pool associated with the second timer may be one or more; this embodiment does not limit the scope of the application. Furthermore, the second timer in this embodiment may also be one or more; this embodiment does not limit the scope of the application either.

[0084] In some embodiments, a first timer and a second timer are started based on a first resource pool. The first timer is associated with a first synchronization source, and the second timer is associated with a second synchronization source. The first synchronization source and the second synchronization source are different.

[0085] After receiving the first data in the first resource pool, the first terminal starts multiple timers. The first synchronization source associated with the first timer and the second synchronization source associated with the second timer are different. It can also be understood that after the first terminal receives the first data, it starts the first timer and the second timer associated with different synchronization sources and executes DRX within the time interval of the first timer and the second timer and the corresponding resource pool.

[0086] In this embodiment, the second resource pool associated with the second timer may be one or more; this embodiment does not limit the scope of the application. Furthermore, the second timer in this embodiment may also be one or more; this embodiment does not limit the scope of the application either.

[0087] It should be noted that the above embodiments are only illustrated using timers as an example. The types of timers involved in the above embodiments will be described below.

[0088] In some embodiments, the timer includes any one of an inactivity timer, an RTT (Round-Trip Time) timer, and a re-transmission timer.

[0089] The `nactivity timer` indicates the duration required for the first terminal to enter a sleep state after receiving the first data. The `RTT timer` indicates the duration for which the first terminal will not receive retransmitted data after receiving the first data. The `re-transmission timer` indicates the duration for which the first terminal will receive retransmitted data after receiving the first data.

[0090] The following will explain how the first terminal executes DRX when the timer is one of the different types of timers mentioned above:

[0091] The first type: The timer includes an inactivity timer, which receives third data within at least one timed duration corresponding to at least one inactivity timer that is enabled and within the corresponding resource pool.

[0092] In this embodiment, the first terminal starts at least one inactivity timer based on the first resource pool, and receives third data within at least one timed duration corresponding to the at least one inactivity timer and the corresponding resource pool. If no third data is received within the timed duration corresponding to the inactivity timer, the first terminal enters a sleep state. If third data is received within the timed duration corresponding to the inactivity timer, the inactivity timer restarts timing until no more third data is received within the timed duration corresponding to the inactivity timer, at which point the first terminal enters a sleep state.

[0093] The sleep state is used to indicate that the first terminal is not receiving data. The method by which the first terminal starts at least one inactivity timer is similar to the method by which at least one timer is started in the above embodiment, and will not be described again here.

[0094] It should be noted that the embodiments in this application are only used as an example of entering a sleep state after the timed duration corresponding to the inactivity timer has ended. In another embodiment, if the first terminal also has other timers enabled, and these other timers do not cause the first terminal to be in a sleep state, the first terminal will enter a sleep state after the timed duration corresponding to the inactivity timer has ended. However, if other timers cause the first terminal to be in a sleep state, it will not enter a sleep state even if the timed duration corresponding to the inactivity timer enabled by the first terminal has ended.

[0095] The second type: The timer includes an RTT timer, and the first terminal is in a sleep state for the duration corresponding to at least one activated RTT timer.

[0096] The sleep state is used to indicate that the first terminal is not receiving data.

[0097] In this embodiment, the first terminal activates at least one RTT timer based on the first resource pool, and remains in a sleep state for the specified duration corresponding to the activated at least one RTT timer. The first terminal in the sleep state no longer receives data.

[0098] It should be noted that the embodiments in this application are only illustrated by taking the timer corresponding to the RTT timer's duration as an example of being in a sleep state. In another embodiment, if the first terminal also has other timers enabled, and these other timers do not cause the first terminal to be in a sleep state, the first terminal will be in a sleep state for the duration corresponding to the RTT timer. However, if other timers cause the first terminal to be in a sleep state, it will not be in a sleep state even if the first terminal is within the duration corresponding to the RTT timer's duration.

[0099] The method by which the first terminal enables at least one RTT timer is similar to the method by which at least one timer is enabled in the above embodiments, and will not be described again here.

[0100] The third type: The timer includes a re-transmission timer, which receives retransmitted data within the time limit corresponding to at least one re-transmission timer that is enabled and within the corresponding resource pool.

[0101] In this embodiment of the application, the first terminal starts at least one re-transmission timer based on the first resource pool, and receives retransmitted data within the time interval corresponding to the at least one started re-transmission timer and the corresponding resource pool. If no retransmitted data is received within the time interval corresponding to the re-transmission timer, the first terminal will no longer receive retransmitted data. If retransmitted data is received within the time interval corresponding to the re-transmission timer, the first terminal will end the timing of the re-transmission timer.

[0102] The method by which the first terminal starts at least one re-transmission timer is similar to the method of starting at least one timer in the above embodiments, and will not be described again here.

[0103] The first point to note is that the first data transmitted in the embodiments of this application is PSCCH (Physical Sidelink Control Channel) data or PSSCH (Physical Sidelink Share Channel) data.

[0104] The second point to note is that the embodiments in this application are only illustrated using an RTT timer or a re-transmission timer as an example. In another embodiment, the RTT timer and the re-transmission timer can also be used in combination.

[0105] In some embodiments, the resource pool configured by the first terminal is associated with both an RTT timer and a re-transmission timer. The first terminal enables both the RTT timer and the re-transmission timer based on the first resource pool. The first terminal is in a sleep state during the timed duration of the RTT timer. After the RTT timer ends, the re-transmission timer is enabled, and retransmission data is received during the timed duration of the re-transmission timer.

[0106] In some embodiments, at least one timer is configured for at least one of broadcast, multicast, or unicast communication methods.

[0107] In this embodiment, the first terminal starts a timer to execute DRX when it is in at least one of broadcast communication, multicast communication, or unicast communication. However, if the first terminal is in other communication modes, it will not start a timer to execute DRX.

[0108] In some embodiments, at least one timer is targeted at a source, which is a terminal that sends data to a first terminal.

[0109] In this embodiment of the application, when the first terminal receives the first data sent by the source, it starts a timer to execute DRX.

[0110] In some embodiments, at least one timer is used for a specific message.

[0111] In this embodiment, if the first data received by the first terminal is a specific message, a timer is started to execute DRX. However, if the first data received by the first terminal is another message, the timer is not started to execute DRX. Optionally, the specific message is a DCR (Direct Communication Request) message.

[0112] This application provides a method for configuring a terminal to perform DRX. The first terminal receives first data in a resource pool using different or the same synchronization source, and performs DRX based on the reference duration corresponding to the first resource pool that receives the first data. This breaks the limitation that DRX cannot be performed when receiving data in resource pools using different synchronization sources, expands the ways to configure the terminal to perform DRX, and thus improves the communication effect.

[0113] Figure 4 A flowchart of a DRX configuration method provided in an exemplary embodiment of this application is shown, the method including:

[0114] 410. The first terminal starts at least one timer.

[0115] The first terminal is configured with at least two resource pools, and the at least two resource pools include resource pools using different synchronization sources. Each resource pool includes at least one resource.

[0116] In this embodiment of the application, each of the at least two resource pools has a corresponding reference duration, so the first terminal can perform DRX based on the reference durations corresponding to the at least two resource pools.

[0117] The reference duration for each resource pool is set by the terminal, by the operator, or by other means.

[0118] In some embodiments, the reference duration of each resource pool is indicated by the timing duration of the timer associated with the resource pool, which can also be understood as the timing duration of each timer being the reference duration of the corresponding resource pool.

[0119] The first terminal starts at least one timer so that the first terminal executes DRX within the time duration of the at least one timer.

[0120] In some embodiments, a timer associated with each of at least two resource pools is started.

[0121] In this embodiment of the application, the first terminal directly starts a timer associated with each of the at least two resource pools. Each timer starts counting, and the first terminal then executes DRX within the timer's duration.

[0122] Optionally, resource pools using the same synchronization source are associated with the same timer. The first terminal is configured with at least two resource pools, and resource pools using the same synchronization source are associated with the same timer, while resource pools using different synchronization sources are associated with different timers.

[0123] For example, the first terminal is configured with resource pool 1, resource pool 2 and resource pool 3. Resource pool 1 and resource pool 2 use the same synchronization source, while resource pool 3 uses a different synchronization source than resource pool 1 and resource pool 2. Therefore, resource pool 1 and resource pool 2 use the same timer, while resource pool 3 uses a different timer.

[0124] In some embodiments, a first timer is started, which is associated with multiple resource pools, and the multiple resource pools use the same synchronization source.

[0125] In this embodiment, multiple resource pools are associated with a timer. A first terminal starts a first timer, which is associated with multiple resource pools that use the same synchronization source.

[0126] It should be noted that the embodiments in this application are only illustrated by taking the first terminal starting a first timer as an example. However, the first terminal can start multiple first timers, and the multiple resource pools associated with each first timer use the same synchronization source, but the multiple first timers are different timers.

[0127] For example, the first terminal starts the first timer S and the first timer K. The multiple resource pools associated with the first timer S use the synchronization source Q, while the multiple resource pools associated with the second timer K use the synchronization source O.

[0128] In some embodiments, a first timer is started, which is associated with multiple resource pools, and the multiple resource pools use different synchronization sources.

[0129] 420. The first terminal executes DRX within the duration of at least one timer.

[0130] If the first terminal starts at least one timer through the above step 410, then DRX will be executed within the time duration of at least one timer.

[0131] It should be noted that the timer in this embodiment is an onduration timer. The onduration timer indicates the duration of the first terminal's wake-up state, which indicates that the first terminal is in a data receiving state.

[0132] The following explains how the first terminal executes DRX when the timer in this embodiment is an onduration timer:

[0133] In some embodiments, the first terminal receives first data within at least one timed duration corresponding to at least one onduration timer that is enabled and within the corresponding resource pool.

[0134] After the first terminal starts at least one onduration timer, and each onduration timer corresponds to a resource pool, the first terminal receives the first data within the time limit corresponding to each onduration timer and the corresponding resource pool. When the first terminal is not within the time limit of the onduration timer, it enters a sleep state.

[0135] It should be noted that the embodiments in this application only illustrate the example of receiving data within the time interval corresponding to the onduration timer and entering a sleep state when the time interval is not within the onduration timer. In another embodiment, if the first terminal also activates other timers, and these other timers do not cause the first terminal to be in a sleep state, the first terminal will enter a sleep state when the time interval corresponding to the onduration timer is not within the onduration timer. However, if other timers cause the first terminal to be in a sleep state, it will not enter a sleep state even if the first terminal is not in a sleep state when the time interval corresponding to the onduration timer is not within the onduration timer.

[0136] In some embodiments, the first terminal receives first data based on the DRX period, the DRX start time, and at least one onduration timer that is enabled.

[0137] The DRX period indicates the interval at which the onduration timer is activated once, and the DRX start time indicates the moment when the onduration timer is activated for the first time.

[0138] When the first terminal starts the onduration timer, it starts at a determined DRX start time, and starts once every DRX cycle.

[0139] It should be noted that the DRX period and DRX start time in the embodiments of this application are defined by the terminal according to the DFN (Direct Frame Number).

[0140] In some embodiments, at least one timer is configured for at least one of broadcast, multicast, or unicast communication methods.

[0141] In some embodiments, at least one timer is targeted at a source sender, which is a terminal that sends data to a first terminal.

[0142] In some embodiments, at least one timer is used for a specific message.

[0143] In some embodiments, the specific message is a DCR message.

[0144] In this embodiment of the application, at least one timer targets the content described above. Figure 3 The timers in the embodiments are similar to those in the examples, and will not be repeated here.

[0145] It should be noted that the embodiments in this application are only illustrated by taking the execution of DRX by starting a timer on the first terminal as an example. In another embodiment, the first terminal does not need to execute DRX by starting a timer, but executes DRX within a reference duration corresponding to at least two resource pools.

[0146] This application provides a method for configuring a terminal to perform DRX.
