[0066] Figure 1 It is a schematic diagram of the application scenario of the embodiment of the present application.

[0067] As Figure 1 shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 through the air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0068] It should be understood that the embodiments of the present application are only exemplarily illustrated by the communication system 100, but the embodiments of the present application are not limited thereto. That is to say, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc. For the convenience of description, hereinafter, the embodiments of the present application will be described by taking the 5th Generation (5G) New Radio (NR) communication system as an example.

[0069] The present application describes various embodiments in combination with network devices and terminal devices.

[0070] Among them, the network device 120 may refer to any entity on the network side used to send or receive signals. For example, it may be a user equipment for Machine Type Communication (MTC), an Evolutional Node B (eNB or eNodeB) in LTE, a base station device in a 5G network, etc.

[0071] In addition, the terminal device 110 can be any terminal device. Specifically, the terminal device 110 can communicate with one or more core networks via a Radio Access Network (RAN), and can also be referred to as an access terminal, a User Equipment (UE), a user unit, a user station, a mobile station, a mobile phone, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. For example, it can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, and a terminal device in a 5G network, etc.

[0072] In New Radio (NR), a Semi-Persistent Scheduling (SPS) timer is defined. Specifically, the following are defined:

[0073] 1. When a retransmitted data / newly transmitted data is sent on a semi-static resource / or a dynamic resource scheduled based on a semi-static Radio Network Temporary Identifier (RNTI), this timer starts;

[0074] 2. When this timer is running, if the user has semi-static resources at the current time, the user does not perform any transmission;

[0075] 3. When this timer is running and the user receives a dynamic resource scheduled based on a semi-static RNTI, this timer stops or starts, and based on the above 1, this timer restarts.

[0076] However, this timer does not start or stop or start with dynamic resources scheduled based on a Cell Radio Network Temporary Identifier (C-RNTI), and has relatively weak compatibility with the existing system framework.

[0077] Therefore, in the embodiments of this application, a method for managing a timer is proposed, which can effectively improve the compatibility of the SPS timer with the existing system framework.

[0078] Figure 2It is a schematic flowchart of the method for managing a timer according to an embodiment of the present application.

[0079] As Figure 2 shown, the method includes:

[0080] 210, the terminal device receives a first Physical Downlink Control Channel (PDCCH) scrambled with a C-RNTI.

[0081] 220, the terminal device determines whether to stop or start the SPS timer of the terminal device.

[0082] It should be understood that in the embodiment of the present application, after the network device establishes a connection with the terminal device (connected), the terminal device descrambles the PDCCH through the C-RNTI or SPS-RNTI to obtain scheduling information. Then, according to the scheduling information, the resource location of the Physical Downlink Shared Channel (PDSCH) is determined, and downlink data is obtained at the PDSCH resource location.

[0083] It should also be understood that the resources obtained by the terminal device by descrambling the PDCCH through the C-RNTI to obtain scheduling information are dynamically scheduled resources, and the resources obtained by the terminal device by descrambling the PDCCH through the SPS-RNTI to obtain scheduling information can be semi-static scheduling SPS resources (for example, resources after activating SPS), or can also be dynamic resources (for example, resources for retransmission).

[0084] In the prior art, when the SPS timer is running, the terminal device receives dynamically scheduled resources based on a semi-static RNTI, and the timer first stops and then restarts. After the SPS timer receives dynamically scheduled resources based on a Cell Radio Network Temporary Identifier (C-RNTI), there are no relevant regulations regarding the SPS timer.

[0085] In the embodiment of the present application, after the terminal device receives the first PDCCH, the SPS timer can be started or stopped or started along with the dynamically scheduled resources based on the C-RNTI, thereby effectively improving the compatibility of the SPS timer with the existing system framework.

[0086] Next, the implementation manner of stopping or starting the SPS timer after the terminal device receives the first PDCCH will be described:

[0087] In one embodiment, when the terminal device meets a preset condition, it determines to stop or start the SPS timer, where the preset condition is the criterion for the terminal device to determine whether to stop or start the SPS timer after obtaining the first PDCCH.

[0088] The following gives an exemplary description of the implementation manner of stopping the SPS timer after the terminal device receives the first PDCCH:

[0089] Optionally, when the terminal device meets a first condition, it determines to stop the SPS timer, where the first condition is the criterion for the terminal device to determine whether to stop the SPS timer after obtaining the first PDCCH.

[0090] For example, when the terminal device determines that the hybrid automatic repeat request (HARQ) process corresponding to the first PDCCH uses the resources scheduled by the PDCCH scrambled with the SPS RNTI for uplink data transmission before using the resources scheduled by the first PDCCH, it stops the SPS timer.

[0091] For another example, when the terminal device determines that the HARQ process corresponding to the first PDCCH of the terminal device uses the SPS resources for uplink data transmission before using the resources scheduled by the first PDCCH, it stops the SPS timer.

[0092] For another example, when the terminal device determines that the SPS timer is running, it stops the SPS timer.

[0093] It should be understood that the implementation manner of the operation (i.e., start) of the SPS timer in the embodiments of the present application is not specifically limited. For example, before the terminal device determines whether to stop or start the SPS timer, the terminal device may send new data to the network device on the SPS resources, or send retransmission data to the network device on the resources scheduled by the second PDCCH scrambled with the SPS radio network temporary identity; thus, the terminal device starts the SPS timer.

[0094] The following gives an exemplary description of the implementation manner of stopping the SPS timer after the terminal device receives the first PDCCH:

[0095] Optionally, when the terminal device meets a second condition, it determines to start or restart the SPS timer, where the second condition is the criterion for the terminal device to determine whether to start the SPS timer after obtaining the first PDCCH.

[0096] For example, when the terminal device determines that SPS resources are configured, it starts or restarts the SPS timer.

[0097] Further, when the terminal device determines that the SPS resource is configured and the SPS resource of the terminal device is activated, the SPS timer is started or restarted.

[0098] It should be understood that the specific embodiments for determining to stop or start the SPS timer when the terminal device meets the preset conditions are only exemplary descriptions, and the embodiments of the present application are not limited thereto.

[0099] In another embodiment, before the terminal device determines whether to stop or start the SPS timer, it may receive configuration information sent by the network device, where the configuration information is used for the terminal device to determine whether to stop or start the SPS timer after obtaining the first PDCCH.

[0100] Thus, the terminal device determines whether to stop or start the SPS timer according to the configuration information.

[0101] Figure 3 It is a schematic flowchart of the method for transmitting information according to the embodiments of the present application.

[0102] Specifically, as Figure 3 shown, the method includes:

[0103] 310. The network device sends configuration information to the terminal device, where the configuration information is used for the terminal device to determine whether to stop or start the SPS timer after obtaining the first PDCCH.

[0104] 320. The network device sends the first PDCCH to the terminal device.

[0105] 330. The terminal device determines whether to stop or start the SPS timer according to the configuration information.

[0106] Further, the terminal device receives radio resource control (RRC) signaling sent by the network device, and the RRC signaling includes the configuration information.

[0115] Optionally, the processing unit 420 is more specifically configured to:

[0116] When it is determined that the terminal device uses SPS resources for uplink data transmission before the hybrid automatic repeat request (HARQ) process corresponding to the first PDCCH uses the resources scheduled by the first PDCCH, stop the SPS timer.

[0125] Optionally, the transceiver unit 410 is further configured to:

[0127] Determine whether to stop or start the SPS timer according to the configuration information.

[0128] Optionally, the transceiver unit 410 is specifically configured to:
