Referring to fig. 1, fig. 1 is a schematic diagram of a communication system architecture provided in an embodiment of the present application, where the communication system includes a network device and a terminal device. As shown in fig. 1, a network device may communicate with a terminal device. The communication system may be a 5G communication system (e.g., a New Radio (NR)), a communication system in which multiple communication technologies are merged (e.g., a communication system in which an LTE technology and an NR technology are merged), or a communication system evolved later. The form and number of the network devices and the terminal devices shown in fig. 1 are only for example and do not constitute a limitation to the embodiments of the present application.

The terminal equipment in the application is equipment with a wireless communication function, can be deployed on land and comprises an indoor or outdoor, a handheld, a wearable or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.).

The terminal device may also be a handheld device with wireless communication capabilities, a vehicle mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, etc. The terminal devices in different networks may be called different names, for example: a terminal device, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or user equipment, a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) telephone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a terminal device in a 5G network or a future evolution network, etc.

Unlicensed spectrum is a nationally and regionally divided spectrum available for communication by radio devices, which is generally considered a shared spectrum, i.e., a spectrum that can be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government.

In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of "Listen Before Talk (LBT)", that is, before the communication device performs signal transmission on a channel of an unlicensed spectrum, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; 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 transmit signals. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the Channel of the unlicensed spectrum cannot exceed the Maximum Channel Occupancy Time (MCOT).

However, in the Rel-16NR system, due to the relaxed constraint, the uplink resource occupies a resource in the time domain in a more relaxed scenario, so that in some scenarios (for example, the uplink resource occupies part or all of at least two time slots in the time domain), there is no corresponding timer start or stop rule support, which is not favorable for the transmission of the uplink resource.

In view of the above problem, embodiments of the present application provide a timer setting method, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2A, fig. 2A is a schematic flowchart of a timer setting method according to an embodiment of the present application, which includes at least some of the following contents:

step 201: the method comprises the steps that network equipment sends first indication information to terminal equipment, wherein the first indication information carries configuration information used for indicating first uplink resources of the terminal equipment;

step 202: the terminal equipment determines the first uplink resource based on the first indication information and determines a second uplink resource based on the first uplink resource;

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 a minimum interval time for the terminal device to expect the downlink retransmission to arrive, and the second timer is a time for the terminal device to expect to receive the downlink retransmission.

Wherein the configuration information comprises at least one of: 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, a start symbol in a first time slot occupied by the first uplink resource, an end symbol in a last time slot occupied by the first uplink resource, a resource length of the first uplink resource, and a determination mode of at least one second uplink resource included in the first uplink resource; a starting position of at least one second uplink resource included in the first uplink resource; an ending position of at least one second uplink resource included in the first uplink resource.

In an implementation manner of the present application, the first indication Information is Radio Resource Control (RRC) signaling or Downlink Control Information (DCI).

The first indication information may be a physical layer signaling, a higher layer signaling, or a Media Access Control (MAC) Control Element (CE). For example, the first indication information is an RRC message (e.g., an RRC reconfiguration message) or DCI.

In an implementation manner of the present application, the first uplink resource is a pre-Configured Grant (CG) resource or a Dynamic Grant (DG) resource.

In an implementation manner of the present application, the determining, by the terminal device, a second uplink resource based on the first uplink resource includes:

under a first condition, the terminal device determines a second uplink resource based on the first uplink resource, wherein the first condition includes at least one of the following:

the first uplink resource crosses a time slot boundary;

the duration of the first uplink resource spans variable symbols or downlink symbols.

The first uplink resource crosses a time slot boundary, that is, the first uplink resource occupies part or all of resources in P consecutive time slots in a time domain, where P is an integer greater than 1.

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

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

For another example, fig. 2C is a schematic diagram of a first uplink resource and a second uplink resource provided in an embodiment of the present application. As shown in fig. 2C, a U symbol represents an Uplink symbol (Uplink), a D symbol represents a Downlink symbol (Downlink symbol), an F symbol represents a variable symbol (Flexible symbol), a first Uplink resource occupies an Uplink symbol 2-an Uplink symbol 6 and an Uplink symbol 9-an Uplink symbol 11 of a time slot 0 in a time domain, and a duration of the first Uplink resource spans the variable symbol 7 and the Downlink symbol 8. The first uplink resource is split into two second uplink resources, a second uplink resource 1 and a second uplink resource 2.

In an implementation manner of the present application, the data transmitted between the terminal device and the network device is independently encoded based on the second uplink resource.

For example, as shown in fig. 2B, a transport block 1 (TB) is encoded based on the second uplink resource 1, and a transport block 2 is encoded based on the second uplink resource 2; similarly, as shown in fig. 2C, the transport block 1 is encoded based on the second uplink resource 1, and the transport block 2 is encoded based on the second uplink resource 2. In short, it is the transport block 1 and the transport block 2 that are coded independently.

In an implementation manner 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.

The number of the second uplink resources included in each first uplink resource may be equal to or different from each other, and it should be noted that the total number of the second uplink resources included in the N first uplink resources is M.

The first uplink resource may be an individual resource, may also be a repeat transmission (retransmission), or may also be a resource bundle (bundle).

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

In an implementation manner of the present application, the starting, by the terminal device, a first timer and/or stopping a second timer based on the first uplink resource includes:

and the terminal equipment starts a first timer and/or stops a second timer at N first symbols of N ending moments of N first uplink resources to be transmitted, wherein the N first uplink resources correspond to the N ending moments and the N first symbols one to one.

As shown in fig. 2D, the number of the first uplink resources is 2, the number of the second uplink resources is 4, the first uplink resources include a first uplink resource a and a first uplink resource B, and the second uplink resources include a second uplink resource 1, a second uplink resource 2, a second uplink resource 3, and a second uplink resource 4. The first symbol at the ending time of the first uplink resource a is symbol 5 in slot 1, and the first symbol at the ending time of the first uplink resource B is symbol 5 in slot 3. In N first symbols of N end times of the N first uplink resources transmitted, the terminal device starts the first timer and/or stops the second timer, i.e. starts the first timer and/or stops the second timer in symbol 5 in slot 1 and symbol 5 in slot 3.

The terminal device starts a first timer and/or stops a second timer based on the first uplink resource, and the method comprises the following steps:

in an implementation manner of the present application, at a first symbol of an end time of a first uplink resource N1 of transmission, the terminal device starts a first timer and/or stops a second timer, where the first uplink resource N1 is any one, or a first, or a last one, of N first uplink resources.

Also by way of example, as shown in fig. 2D, at the first symbol of the end time of the transmitted first uplink resource n1, the terminal device starts the first timer and/or stops the second timer, i.e., starts the first timer and/or stops the second timer at symbol 5 in slot 1; alternatively, at symbol 5 in slot 3, the first timer is started and/or the second timer is stopped.

In an implementation manner of the present application, the starting, by the terminal device, the first timer and/or stopping the second timer based on the second uplink resource includes:

and the terminal equipment starts a first timer and/or stops a second timer at M first symbols of M ending moments of M second uplink resources to be transmitted, wherein the M second uplink resources correspond to the M ending moments and the M first symbols one to one.

In the first symbol at the end of the transmitted first uplink resource n1, the terminal device starts the first timer and/or stops the second timer, i.e. starts the first timer and/or stops the second timer in symbol 0 in slot 1, symbol 5 in slot 1, symbol 0 in slot 3 and symbol 5 in slot 3.

and at the first symbol of the end time of the transmitted second uplink resource M1, the terminal device starts a first timer and/or stops a second timer, and the second uplink resource M1 is any one, the first or the last of the M second uplink resources.

Further, for example, as shown in fig. 2D, in the first symbol at the end time of the transmitted first uplink resource n1, the terminal device starts the first timer and/or stops the second timer, that is, starts the first timer and/or stops the second timer in symbol 0 in slot 1, or symbol 5 in slot 1, or symbol 0 in slot 3, or symbol 5 in slot 3.
