[0033] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0034] The embodiments of the present application 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, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication system or other communication systems, etc.

[0035] Generally speaking, traditional communication systems 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 communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0036] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0037] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to licensed spectrum or unlicensed spectrum.

[0038] See also Figure 1 , Figure 1 1 is a schematic diagram of a communication system architecture provided in an embodiment of the present application, wherein the communication system includes a network device and a terminal device. Figure 1 As shown, the network device can communicate with the terminal device. The communication system can be a 5G communication system (such as a new radio (NR)), a communication system integrating multiple communication technologies (such as a communication system integrating LTE technology and NR technology), or a subsequent evolution communication system. Figure 1 The forms and quantities of the network devices and terminal devices shown are for example only and do not constitute a limitation on the embodiments of the present application.

[0039] The terminal device in this application is a device with wireless communication function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons, satellites, etc.). The terminal device can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), etc. The terminal device can also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, etc. Terminal devices may be called different names in different networks, such as: terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), terminal equipment in 5G network or future evolution network, etc.

[0040] The network device in the present application is a device deployed in a wireless access network to provide wireless communication functions. For example, the network device can be a radio access network (RAN) device on the access network side of a cellular network. The so-called RAN device is a device that connects a terminal device to a wireless network, including but not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., Home evolved Node B, or Home Node B, HNB), base band unit (BBU), management entity (MME); for another example, the network device can also be a node device in a wireless local area network (WLAN), such as an access controller (AC), a gateway, or a WIFI access point (AP); for another example, the network device can also be a transmission node or a transmission reception point (TRP or TP) in an NR system.

[0041] Unlicensed spectrum is the spectrum allocated by countries and regions that can be used for radio equipment communications. This spectrum is generally considered to be a shared spectrum, that is, as long as communication equipment in different communication systems meets the regulatory requirements set by the country or region on the spectrum, they can use the spectrum without applying for exclusive spectrum authorization from the government.

[0042] In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist in a friendly manner on the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the "Listen Before Talk (LBT)" principle, that is, before a communication device sends a signal on a channel of the unlicensed spectrum, it needs to first perform channel sensing. Only when the channel sensing result is that the channel is idle can the communication device send a signal; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send a signal. In order to ensure fairness, in one transmission, the duration of the communication device using the channel of the unlicensed spectrum for signal transmission cannot exceed the Maximum Channel Occupancy Time (MCOT).

[0043] However, in the Rel-16NR system, due to the relaxation of restrictions, the scenarios in which uplink resources occupy resources in the time domain are more relaxed, resulting in some scenarios (for example, uplink resources occupy part or all of the resources in at least two time slots in the time domain), without corresponding timer start or stop rule support, which is not conducive to the transmission of uplink resources.

[0044] In response to the above problems, an embodiment of the present application provides a timer setting method, which is described in detail below with reference to the accompanying drawings.

[0045] See also Figure 2A , Figure 2A A flowchart of a timer setting method provided in an embodiment of the present application includes at least part of the following contents:

[0046] Step 201: The network device sends first indication information to the terminal device, where the first indication information carries configuration information for indicating a first uplink resource of the terminal device;

[0047] Step 202: The terminal device determines the first uplink resource based on the first indication information, and determines the second uplink resource based on the first uplink resource;

[0048] Step 203: The terminal device starts a first timer and / or stops a second timer based on the first uplink resource or the second uplink resource, the first timer is the minimum interval time for the terminal device to expect the downlink retransmission to arrive, and the second timer is the time when the terminal device expects to receive the downlink retransmission.

[0049] It can be seen that in an embodiment of the present application, the terminal device receives the first indication information from the network device, and determines the first uplink resource based on the first indication information and determines the second uplink resource based on the first uplink resource, and then starts the first timer and / or the second timer based on the first uplink resource or the second uplink resource, that is, the operation rules of the corresponding timers (the first timer and / or the second timer) are formulated, which is facilitating the transmission of subsequent uplink resources.

[0050] Among them, the configuration information includes at least one of the following: time domain resource information of the first uplink resource, frequency domain resource information of the first uplink resource, the number of time slots occupied by the first uplink resource, the starting symbol in the first time slot occupied by the first uplink resource, the ending symbol in the last time slot occupied by the first uplink resource, the resource length of the first uplink resource, and the method for determining at least one second uplink resource included in the first uplink resource; the starting position of at least one second uplink resource included in the first uplink resource; and the ending position of at least one second uplink resource included in the first uplink resource.

[0051] In an implementation of the present application, the first indication information is radio resource control signaling (Radio Resource Control, RRC) or downlink control information (Downlink Control Information, DCI).

[0052] The first indication information may be physical layer signaling, or high layer signaling, or a media access control layer (Media Access Control, MAC) control element (Control element, CE). For example, the first indication information is an RRC message (such as an RRC reconfiguration message) or a DCI.

[0053] In one implementation of the present application, the first uplink resource is a pre-configured grant (Configured grant, CG) resource or a dynamic grant (Dynamic grant, DG) resource.

[0054] In an implementation of the present application, the terminal device determines the second uplink resource based on the first uplink resource, including:

[0055] Under a first condition, the terminal device determines a second uplink resource based on the first uplink resource, and the first condition includes at least one of the following:

[0056] The first uplink resource crosses a time slot boundary;

[0057] The duration of the first uplink resource spans variable symbols or downlink symbols.

[0058] The first uplink resource crosses time slot boundaries, that is, the first uplink resource occupies part or all of the resources in P consecutive time slots in the time domain, and P is an integer greater than 1.

[0059] For example, Figure 2B is a schematic diagram of a first uplink resource and a second uplink resource provided in an embodiment of the present application. Figure 2BAs shown, the first uplink resource occupies part of the resources in two consecutive time slots (time slot 0 and time slot 1) in the time domain, symbols 9 to 13 in time slot 0 and symbols 0 to 4 in time slot 1. The first uplink resource is split into two second uplink resources - second uplink resource 1 and second uplink resource 2. The second uplink resource 1 occupies the resources from symbol 9 to symbol 13 in time slot 0 in the time domain, and the second uplink resource 2 occupies the resources from symbol 0 to symbol 4 in time slot 1 in the time domain.

[0060] The duration of the first uplink resource spans variable symbols or downlink symbols, that is, the first uplink resource occupies all resources of Q symbols in a complete time slot in the time domain, the Q symbols are discontinuous, and Q is an integer greater than 1.

[0061] Another example to illustrate: Figure 2C is a schematic diagram of a first uplink resource and a second uplink resource provided in an embodiment of the present application. Figure 2C As shown, the U symbol represents an uplink symbol, the D symbol represents a downlink symbol, and the F symbol represents a flexible symbol. The first uplink resource occupies uplink symbols 2 to 6 and uplink symbols 9 to 11 of time slot 0 in the time domain, and the duration of the first uplink resource spans flexible symbol 7 and downlink symbol 8. The first uplink resource is split into two second uplink resources - second uplink resource 1 and second uplink resource 2.

[0062] In one implementation of the present application, data transmitted between the terminal device and the network device is independently encoded based on the second uplink resource.

[0063] For example, Figure 2B As shown, the transport block 1 (Transform block, TB) is encoded based on the second uplink resource 1, and the transport block 2 is encoded based on the second uplink resource 2; similarly, as Figure 2C As shown, transport block 1 is encoded based on the second uplink resource 1, and transport block 2 is encoded based on the second uplink resource 2. In short, transport block 1 and transport block 2 are encoded independently.

[0064] In one implementation of the present application, the number of the first uplink resources is N, the number of the second uplink resources is M, N is an integer greater than 0, and M is an integer greater than N.

[0065] The number of second uplink resources included in each first uplink resource may be equal or unequal. It should be noted that the total number of second uplink resources included in N first uplink resources is M.

[0066] The first uplink resource may be a separate resource, a repeated transmission (repetition), or a resource bundle (bundle).

[0067] At least one of the first uplink resources may be split into at least two second uplink resources, or may not be split.

[0068] In an implementation of the present application, the terminal device starts a first timer and / or stops a second timer based on the first uplink resource, including:

[0069] At the N first symbols of the N end times of the transmitted N first uplink resources, the terminal device starts the first timer and / or stops the second timer, and the N first uplink resources correspond one-to-one to the N end times and the N first symbols.

[0070] For example, Figure 2D is a schematic diagram of a first uplink resource and a second uplink resource provided in an embodiment of the present application. Figure 2D As shown, the number of first uplink resources is 2, the number of second uplink resources is 4, the first uplink resources include first uplink resource A and first uplink resource B, and the second uplink resources include second uplink resource 1, second uplink resource 2, second uplink resource 3 and second uplink resource 4. The first symbol at the end moment of the first uplink resource A is symbol 5 in time slot 1, and the first symbol at the end moment of the first uplink resource B is symbol 5 in time slot 3. At the N first symbols at the N end moments of the transmitted N first uplink resources, the terminal device starts the first timer and / or stops the second timer, that is, at symbol 5 in time slot 1 and symbol 5 in time slot 3, the first timer is started and / or the second timer is stopped.

[0071] The terminal device starts a first timer and / or stops a second timer based on the first uplink resource, including:

[0072] In one implementation of the present application, at the first symbol of the end moment of the transmission of the first uplink resource n1, the terminal device starts the first timer and / or stops the second timer, and the first uplink resource n1 is any one of the N first uplink resources, or the first, or the last.

[0073] Another example is given, such as Figure 2D As shown, at the first symbol at the end moment of the transmission of the first uplink resource n1, the terminal device starts the first timer and / or stops the second timer, that is, at symbol 5 in time slot 1, the first timer is started and / or the second timer is stopped; or, at symbol 5 in time slot 3, the first timer is started and / or the second timer is stopped.

[0074] In an implementation of the present application, the terminal device starts a first timer and / or stops a second timer based on the second uplink resource, including:

[0075] At the M first symbols of the M end times of the transmitted M second uplink resources, the terminal device starts the first timer and / or stops the second timer, and the M second uplink resources correspond one-to-one to the M end times and the M first symbols.

[0076] Another example is given, such as Figure 2D As shown, the first symbol at the end moment of the second uplink resource 1 is symbol 0 of time slot 1, the first symbol at the end moment of the second uplink resource 2 is symbol 5 of time slot 1, the first symbol at the end moment of the second uplink resource 3 is symbol 0 of time slot 3, and the first symbol at the end moment of the second uplink resource 4 is symbol 5 of time slot 3. At the first symbol at the end moment of the transmitted first uplink resource n1, the terminal device starts the first timer and / or stops the second timer, that is, at symbol 0 in time slot 1, symbol 5 in time slot 1, symbol 0 in time slot 3, and symbol 5 in time slot 3, the first timer is started and / or the second timer is stopped.

[0077] In an implementation of the present application, the terminal device starts a first timer and / or stops a second timer based on the second uplink resource, including:

[0078] At the first symbol of the end moment of the transmitted second uplink resource m1, the terminal device starts the first timer and / or stops the second timer, and the second uplink resource m1 is any one of the M second uplink resources, or the first, or the last one.

[0079] Another example is given, such as Figure 2D As shown, at the first symbol at the end moment of the transmission of the first uplink resource n1, the terminal device starts the first timer and / or stops the second timer, that is, at symbol 0 in time slot 1, or symbol 5 in time slot 1, or symbol 0 in time slot 3, or symbol 5 in time slot 3, the first timer is started and / or the second timer is stopped.

[0080] In one implementation of the present application, if the first uplink resource is a nominal repetition, the second uplink resource is an actual repetition; if the first uplink resource is a non-segmented grant, the second uplink resource is a segmented grant.

[0081] In an implementation of the present application, the first timer is drx-HARQ-RTT-TimerUL, and the second timer is drx-RetransmissionTimerUL.

[0082] Specifically, for MAC, if the MAC PDU is transmitted on the CG / if a PDCCH indicates UL transmission, the drx-HARQ-RTT-TimerUL for the HARQ process is started at the first symbol at the end time of the first nominal repetition of the corresponding PUSCH transmission, and / or the drx-RetransmissionTimerUL is stopped. Or;
