Description

Method and device for determining time domain resources for unlicensed transmission

Technical Field

Background

Uplink grant-free transmission is an uplink data transmission method that is to go from beginning to end, that is, when data arrives, a terminal device does not need to send a Scheduling Request (SR) to a network device to Request the network device to allocate uplink transmission resources, and sends uplink data to the network device after waiting for the network device to send grant information, but directly uses resources pre-allocated by the network device and specified transmission parameters to send the uplink data to the network device. Compared with the traditional transmission method based on 'request-grant', the method for transmitting the uplink data of the uplink grant-free transmission, namely the walk-to-go uplink data, has obvious beneficial effects, for example, the uplink grant-free transmission can obviously reduce signaling overhead, transmission delay and power consumption of terminal equipment.

In uplink grant-free transmission, the network device needs to allocate a grant-free resource to the terminal device in advance, specifically including allocating a transmission resource and a transmission parameter to the terminal device. Wherein, the transmission parameters mainly include: the period of the unlicensed resource, the offset parameter of the time domain resource, the time domain resource allocation, the frequency domain resource allocation, the user-specific demodulation reference signal configuration information, the modulation and coding strategy/the size of the transmission block, the repetition times, the power control related parameters, and the like.

In the prior art, there is a method for configuring an unlicensed transmission resource in a double period, that is, an unlicensed transmission resource allocated by a network device to a terminal device has two time domain periods, where a first unlicensed transmission resource in a set of unlicensed transmission resources is configured with a long time domain period, and other unlicensed transmission resources in the set of unlicensed transmission resources are configured with a short time domain period. In the existing method for configuring the unlicensed transmission resources, an overlapping phenomenon occurs between a previous set of unlicensed transmission resources and a next set of unlicensed transmission resources, so that complexity in determining a time unit in which the unlicensed transmission resources of the terminal device are located is high.

However, it is understood that network device 102 may communicate with any number of terminal devices similar to terminal device 116 or terminal device 122.

Fig. 2 is a schematic flow chart of a method 200 for determining time domain resources for unlicensed transmission according to an embodiment of the present application. The terminal device in fig. 2 may be a terminal device of the terminal devices 116, 122 in fig. 1; the network device may be network device 102 in fig. 1. Of course, in an actual system, the number of network devices and terminal devices may not be limited to the example of this embodiment or other embodiments, and will not be described below. The method 200 includes at least the following steps.

201, a terminal device obtains a first time domain period and a second time domain period of an unlicensed transmission resource, where the first time domain period is P₁A time unit, the second time domain period is P₂A time unit of which P₁Greater than or equal to P₂。

Specifically, when allocating the unlicensed transmission resource to the terminal device, the network device may configure the unlicensed transmission resource for the terminal device based on a double period (e.g., a first time domain period and a second time domain period), where the first time domain period includes P₁A time unit, the second time domain period includes P₂A time unit of which P₁Greater than or equal to P₂。

For example, the network device configures a first type of unlicensed transmission resources for the terminal device through the first time domain period, and configures a second type of unlicensed transmission resources for the terminal device through the second time domain period, as shown in fig. 3, that is, in the unlicensed transmission resources configured for the terminal device by the network device, the first type of unlicensed transmission resources are configured with a first time domain period P₁Repeatedly occurring, the second type of unlicensed transmission resources with a second time domain period P₂Repeated, first time domain period P₁The first unlicensed transmission resource is a first type of unlicensed transmission resource, and is set to be in a first time domain period P₁Within a second time domain period P after the first unlicensed transmission resource₂The configured unlicensed transmission resources are a second type of unlicensed transmission resources.

Optionally, the first type of unlicensed transmission resources in the first time domain period is used for the first transmission of a certain data packet by the terminal device, and the second type of unlicensed transmission resources in the first time domain period is used for the non-first transmission of the data packet, so the first time domain period may also be referred to as a period of the unlicensed transmission resources for the first transmission, and the second time domain period may also be referred to as a period of the unlicensed transmission resources for the non-first transmission.

When determining the unlicensed transmission resource allocated by the network device, the terminal device first needs to acquire parameter information related to the unlicensed transmission resource, for example, a first time domain period P of the unlicensed transmission resource is acquired₁And a second time domain period P₂And determining the unlicensed transmission resource allocated to the network device by the network device according to the parameter information related to the unlicensed transmission resource.

Optionally, the parameter information includes the first time domain period P₁And a second time domain period P₂In addition, at least the maximum number of times of retransmission N and the number T of time units included in any one unlicensed transmission resource in the first time domain period may be included, where the maximum number of times of retransmission N is the maximum number of times of sending the same uplink data to the network device before the feedback information sent by the network device is not received, and N is greater than or equal to 1. In the repeated transmission, the different transmissions may be of the same redundancy version of the same uplink data, or of different redundancy versions of the same data.

The maximum number of retransmissions N is the maximum number of retransmissions including the first transmission of uplink data.

Optionally, any one time unit included in any one of the unlicensed transmission resources in the first time domain period and the second time domain period may be any one of an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a mini-slot (mini-slot), a slot, and a subframe.

Optionally, the parameter information may be notified to the terminal device by the network device in any one of the following manners: transmitting any one of a higher layer signaling (e.g., Radio Resource Control (RRC) signaling) or L1/L2 signaling (e.g., Downlink Control Information (DCI) or Medium Access Control Element (MAC CE)) to the terminal device; alternatively, the network device and the terminal device may be agreed in advance, for example, specified by a standard; alternatively, the parameter information may also be a default value, which is not particularly limited in this embodiment of the present application.

202, the terminal device obtains the number k of the license-exempt transmission resources configured by the first time domain period P1 and the second time domain period P2 in the first time domain period.

Specifically, in 201, the terminal device determines a first time domain period P of the unlicensed transmission resource₁And a second time domain period P₂In 202, the terminal device needs to further determine the number k of unlicensed transmission resources included in the first time domain period.

In this embodiment, the unlicensed transmission resource included in the first time domain period is based on the first time domain period P₁Configured unlicensed transmission resources and based on the second time-domain period P₂A configured unlicensed transmission resource. The k unlicensed resources include 1 unlicensed transmission resource configured based on a first time domain period and (k-1) unlicensed transmission resources configured based on a second time domain period.

203, the terminal device determines an index of a time unit where the unlicensed transmission resource for unlicensed transmission is located according to the first time domain period, the second time domain period, and the number k of unlicensed transmission resources in the first time domain period.

Specifically, in 202, the terminal device determines the number k of the unlicensed transmission resources included in the first time domain period, and in 203, the terminal device determines an index of a time unit in which the unlicensed transmission resources for unlicensed transmission are located according to the first time domain period, the second time domain period, and the number k of the unlicensed transmission resources in the first time domain period.

Therefore, in the embodiment of the present application, by determining the number k of the unlicensed transmission resources in the first time domain period, and enabling the terminal device to determine the index of the time unit where the unlicensed transmission resources for unlicensed transmission are located according to the first time domain period, the second time domain period, and the number k of the unlicensed transmission resources in the first time domain period, it is possible to configure the unlicensed transmission resources for the terminal device in two adjacent first time domain periods without overlapping.

A method for determining the number k of unlicensed transmission resources included in the first time domain period by the terminal device is described in detail below.

By way of example and not limitation, a method for determining the number k of unlicensed transmission resources included in the first time-domain period is described with an example in which any one of the unlicensed transmission resources in the first time-domain period includes one time unit.

Method 1

The terminal equipment is according to the first time domain period P₁And a second time domain period P₂The number k of unlicensed transmission resources within the first time-domain period is determined.

Specifically, the terminal device determines the number k of the unlicensed transmission resources in the first time domain period according to the following relation:

k＝ceil(P₁/P₂) (1)

where ceil denotes rounding up.

E.g. the first time domain period P₁If the number of time units included in the first time domain period is 5 and the number of time units included in the second time domain period is 2, determining that the number k of the unlicensed transmission resources in the first time domain period is as follows according to the relation 1:

k＝ceil(5/2)＝3

that is, it is determined that the number of the unlicensed transmission resources in the first time domain period is 3, and a distribution diagram of the unlicensed transmission resources is shown in fig. 4.

Method 2

The terminal equipment is according to the first time domain period P₁A second time domain period P₂And time units contained in any one of the unlicensed transmission resources within the first time domain periodAnd the quantity T determines the quantity k of the license-free transmission resources in the first time domain period.

k＝floor[(P₁-T)/P₂]+1 (2)

wherein floor denotes rounding down.

E.g. the first time domain period P₁If the number of time units included in the first time domain period is 8 and the number of time units included in the second time domain period is 3, determining that the number k of the unlicensed transmission resources in the first time domain period is as follows according to the relation 1:

k＝floor[(8-1)/3]+1＝3

that is, it is determined that the number of the unlicensed transmission resources in the first time domain period is 3, and a distribution diagram of the unlicensed transmission resources is shown in fig. 5.

Method 3

The terminal equipment determines the number k of the authorization-free transmission resources in the first time domain period according to the first time domain period, the second time domain period and the maximum repeated transmission times N.

k＝min[ceil(P₁/P₂),N](3)

wherein the min function is operative to return a given parameter ceil (P)₁/P₂)、N]Minimum value of (1).

E.g. the first time domain period P₁The number of time units included in the first time domain period is 8, the number of time units included in the second time domain period is 2, and the maximum number of times of repeated transmission N is 4, then the number k of the unlicensed transmission resources in the first time domain period is determined according to the relation 1:

k＝min[ceil(8/2)，N]＝4

that is, it is determined that the number of the unlicensed transmission resources in the first time domain period is 4, and a distribution diagram of the unlicensed transmission resources is shown in fig. 6.

Method 4

The terminal device determines the number k of the unlicensed transmission resources in the first time domain period according to the first time domain period, the second time domain period, the number T of time units contained in any one of the unlicensed transmission resources in the first time domain period, and the maximum number N of repeated transmission times.

k＝min[floor[(P₁-T)/P₂]+1,N](4)

e.g. the first time domain period P₁The number of time units included in the first time domain period is 10, the number of time units included in the second time domain period is 2, and the maximum number of times of repeated transmission N is 4, then the number k of the unlicensed transmission resources in the first time domain period is determined according to the relation 1:

k＝min[floor[(10-1)/2]+1，N]＝4

that is, it is determined that the number of the unlicensed transmission resources in the first time domain period is 4, and a distribution diagram of the unlicensed transmission resources is shown in fig. 7.

For the above methods 3 and 4, N in the relations (3) and (4) may also be replaced by other parameters, for example, N in the relations (3) and (4) may be replaced by L, where L is used to indicate that L-1 second-class unlicensed transmission resources are configured after the first-class unlicensed transmission resources in the first time domain period.

An alternative to relation (3) is shown in relation (5):

k＝min[ceil(P₁/P₂),L](5)

for relation (4), an alternative form is shown as relation (6):

k＝min[floor[(P₁-T)/P₂]+1,L](6)

optionally, the parameter L may be notified to the terminal device by the network device through any one of the following manners: the network equipment transmits any one of higher layer signaling (for example, RRC signaling) or L1/L2 signaling (for example, DCI) or MAC CE to the terminal equipment; or, the agreement between the network device and the terminal device may be made in advance; alternatively, the parameter information may also be a default value, which is not particularly limited in this embodiment of the present application.

Method 5

And the terminal equipment determines the number k of scheduling-free transmission resources distributed to the terminal equipment by the network equipment according to the second time domain period.

For example, as shown in FIG. 8, the first time domain period P₁The number of the included time units is 8, the number of the time units included in the second time domain period is 3, and the terminal device determines that only 2 second-class unlicensed resources can be included in one first time domain period according to the size of the second time domain period, and ignores or discards the second-class unlicensed transmission resources located in the next first time domain period of the current first time domain period, where the second-class unlicensed transmission resources ignored or discarded by the terminal device are shown in fig. 8.

It should be noted that the relational expressions listed in the above methods are only exemplary and do not limit the embodiments of the present application.

By way of example and not limitation, the method for determining the number k of the unlicensed transmission resources included in the first time-domain period is described by taking an example in which any one of the unlicensed transmission resources in the first time-domain period includes one time unit, and the time unit is a mini-slot (mini-slot).

It should be noted that, when any time unit included in any one of the unlicensed transmission resources in the first time domain period is a mini-slot, the terminal device needs to obtain the parameter information and also determine format information of the mini-slot, where the format information of the mini-slot at least includes: the number of orthogonal frequency division multiplexing OFDM symbols included in each mini-slot and the position of the start OFDM symbol in each slot of each mini-slot, or the position of the start OFDM symbol in each slot of each mini-slot and the position of the end OFDM symbol in each slot of each mini-slot.

TABLE 9

In the first method, the format of the mini-slot may be specified by a standard, and the network device determines the format of the mini-slot, and transmits the format number of the mini-slot to the terminal device, so that the terminal device determines the format of the mini-slot according to the number. The embodiments of the present application are not limited thereto.

For example, the network device may also directly configure the format of the mini-slot in the slot, and send the specific format information of the configured mini-slot (for example, the format information described in the foregoing table) to the terminal device through any one of the following signaling: higher layer signaling (e.g., RRC signaling) or L1/L2 signaling (e.g., DCI) or MAC CE;

alternatively, the format of the mini-slot in the slot may be agreed in advance by the network device and the terminal device (i.e., agreed by the standard followed by the network device and the terminal device), or may be in a default format.

After determining the format information of the mini-slot configured for the terminal device by the network device, the terminal device may further determine the number k of the unlicensed transmission resources included in the first time domain period.

Specifically, the network device informs the terminal device of the format numbers of the first time domain period, the second time domain period, and the mini-slot. For example, the network device informs the terminal device that the first time domain period includes 7 mini-slots, the second time domain period includes 2 mini-slots, and informs the terminal device that the format of the mini-slots occupies two OFDM symbols for each mini-slot, then the terminal device determines, according to relation (1), that the number k of the unlicensed transmission resources included in the first time domain period is:

k＝ceil(7/2)＝4

it should be noted that, if the network device does not indicate the size of the first time domain cycle to the terminal device, when determining the amount of the license-exempt transmission resource, the terminal device defaults to set the size of the first time domain cycle as the number of mini slots included in one slot.

Method two

And the network equipment issues mini-slot format information through the authorization-free time domain resource allocation parameter, wherein the mini-slot format information is used for indicating the selected or determined mini-slot format.

Optionally, the format information of the mini-slot at least includes: the number of orthogonal frequency division multiplexing OFDM symbols included in each mini-slot and the position of the start OFDM symbol in each slot of each mini-slot, or the position of the start OFDM symbol in each slot of each mini-slot and the position of the end OFDM symbol in each slot of each mini-slot.

Specifically, the network device issues an offset parameter of the time domain resource, where the offset parameter of the time domain resource is used to indicate an index of a time unit (e.g., slot) where a configured first unlicensed transmission resource is located, or to indicate an index of a time unit where the unlicensed transmission resource is initialized.

For example, the terminal device considers that, starting from the slot position indicated by the bias parameter of the time domain resource, all slots behind the slot are configured with the unlicensed transmission resource, and all mini-slots in the slots indicated by the mini-slot format information are configured with the unlicensed transmission resource.

For another example, the network device issues a time domain cycle of the unlicensed transmission resource, where the time domain cycle refers to a cycle in which slots configured with the unlicensed transmission resource repeatedly appear in the time domain, and the terminal device considers that, starting from a slot position indicated by a bias parameter of the time domain resource, only the unlicensed transmission resource is configured on the slots appearing in the cycle indicated by the time domain cycle of the unlicensed transmission resource, and all mini-slots in the slots indicated by the mini-slot format are configured as the unlicensed transmission resource.

It should be noted that the format number or each parameter of the mini timeslot may be notified to the terminal device by the network device in any one of the following manners: the network equipment transmits any one of higher layer signaling (for example, RRC signaling) or L1/L2 signaling (for example, DCI) or MAC CE to the terminal equipment; alternatively, the network device and the terminal device may be agreed in advance, and this is not particularly limited in the embodiment of the present application.

In 202, the terminal device determines the number k of the unlicensed transmission resources in the first time domain period, and for performing uplink transmission using the unlicensed resources allocated to the terminal device by the network device, the terminal device further needs to determine an index of a time unit in which the unlicensed transmission resources are located.

A method for determining, by a terminal device, an index of a time unit in which an unlicensed transmission resource configured for the terminal device is located is described below.

Optionally, the terminal device determines the index of the time unit in which the unlicensed transmission resource is located according to the index of the time unit in which the first unlicensed transmission resource is located, the first time domain period, the second time domain period, and the number k of unlicensed transmission resources in the first time domain period.

It should be noted that, when any one of the unlicensed transmission resources in the first time domain period includes multiple time units, the index of the time unit in which the unlicensed transmission resource is located is the index of the first time unit in the multiple time units included in the unlicensed transmission resource.

For example, when any one of the unlicensed transmission resources in the first time domain period includes a plurality of OFDM symbols, the index of the time unit in which the unlicensed transmission resource is located is the index of the first OFDM symbol in the plurality of OFDM symbols.

It should be further noted that, the index of the time unit where the first unlicensed transmission resource is located is used to initialize the unlicensed transmission resource, and is referred to as start _ index, and the index of the time unit where the first unlicensed transmission resource is located may be notified to the terminal device by the network device at least through any one of the following manners: the network equipment transmits any one of higher layer signaling (for example, no RRC signaling) or L1/L2 signaling (for example, DCI) or MAC CE to the terminal equipment; alternatively, the network device and the terminal device may be agreed in advance, for example, specified by a standard; alternatively, the index of the time unit in which the first unlicensed transmission resource is located may also be a default value, which is not particularly limited in this embodiment of the application.

By way of example and not limitation, the terminal device determines an index of a time unit in which the Y-th unlicensed transmission resource is located according to any one of the following relations:

-TU_index＝Starting_index+floor(Y/k)*P₁+(Y mod k)*P₂(7)

-TU_index＝[Starting_index+floor(Y/k)*P₁+(Y mod k)*P₂]mod X (8)

-TU_index＝Starting_index+floor(Y/k)*P₁+(Y mod k)*P₂+F₂(9)

-TU_index＝[Starting_index+floor(Y/k)*P₁+(Y mod k)*P₂+F₂]mod X (10)

wherein,

-F₂to correct the parameters, F₂Is associated with the value of Y,

-X is a preset non-negative integer,

By way of example and not limitation, the terminal device may further determine an index of a time unit in which (D × k + e) _ th unlicensed transmission resource is located according to any one of the following relations, where D represents a sequence number of the first time domain period, k is the number of unlicensed transmission resources included in each first time domain period, e is a non-negative integer, and 0 ≦ e ≦ k-1, and for any one value of D, the value of e will traverse from 0 to (k-1):

-TU_index＝Starting_index+D*P₁+e*P₂(11)

-TU_index＝[Starting_index+D*P₁+e*P₂]mod X (12)

-TU_index＝Starting_index+D*P₁+e*P₂+F₂(13)

-TU_index＝[Starting_index+D*P₁+e*P₂+F₂]mod X (14)

wherein,

-F₂to correct the parameters, F₂Is associated with the value of (D x k + e),

-X is a preset non-negative integer,

Note that TU _ index calculated in the relations (7) to (14) is a global index of a time unit. Further, the global index of the time unit and the local index of the time unit can be used. In this application, both the local index of a time cell and the global index of a time cell can indicate the location of the time cell, and they can be referred to as the index of the time cell.

When the time unit is specifically an OFDM symbol, the global index of an OFDM symbol is determined by the radio frame number of the OFDM symbol, the index of the subframe of the OFDM symbol in the radio frame, the index of the slot of the OFDM symbol in the subframe, the index of the OFDM symbol in the slot, the number of subframes included in one radio frame, the number of slots included in one subframe, and the number of symbols included in one slot. The local index of the OFDM symbol is represented by the radio frame number of the OFDM symbol, the index of the subframe of the OFDM symbol in the subframe, the index of the time slot of the OFDM symbol in the subframe and the index of the OFDM symbol in the time slot. When the time unit is specifically a slot (slot), the global index of the slot is determined by the number of a radio frame where the slot is located, the index of a subframe where the slot is located in the radio frame, the index of the slot in the subframe, the number of subframes contained in one radio frame, and the number of slots contained in one subframe. And jointly representing the local index of the slot by the frame number of the wireless frame where the slot is located, the index of the subframe where the slot is located in the subframe, and the index of the slot in the subframe.

When the time unit is a mini-slot (mi-slot), the global index of the mini-slot is determined by the radio frame number of the mi-slot, the index of the subframe of the mi-slot in the radio frame, the index of the slot of the mi-slot in the subframe, the index of the mi-slot in the slot, the number of subframes contained in the radio frame, the number of slots contained in the subframe, and the number of mi-slots contained in the slot. And the local index of the mim-slot is represented by the frame number of the mim-slot, the index of the subframe of the mim-slot in the frame, the index of the slot of the mim-slot in the subframe and the index of the mim-slot in the slot.

The following describes a method for determining a local index corresponding to the start _ index and the TU _ index for different types of time units. Assuming that each Radio Frame (Radio Frame) consists of M _ subframe subframes (subframes), each subframe consists of M _ slot slots (slots); each time slot consists of M _ mini-slots (mini-slots); each slot consists of M _ symbol OFDM symbols (symbols). The index subframe _ index of the M _ subframe subframes in one frame is 0, 1, …, M _ subframe-1, and the index slot _ index of the M _ slot in one subframe is 0, 1, …, M _ slot-1, M _ mini-slot in one slot is 0, 1, …, M _ mini-slot-1, and the index symbol _ index of the M _ symbol in one slot is 0, 1, …, M _ symbol-1.

The network device may notify the terminal device of the M _ subframe, the M _ slot, the M _ mini-slot, and the M _ symbol in any one of the following manners: the network equipment transmits any one of higher layer signaling (for example, RRC signaling) or L1/L2 signaling (for example, DCI) or MAC CE to the terminal equipment; or, the agreement between the network device and the terminal device may be made in advance; alternatively, the M _ subframe, M _ slot, and M _ mini-slot may also take default values, which is not particularly limited in this embodiment of the present application.

By way of example and not limitation, when any one of the unlicensed transmission resources in the first time domain period includes one or more time units, and the time unit is a slot, the TU _ index may be further represented as:

TU_index＝SFN*M_subframe*M_slot+subframe_index*M_slot+slot_index(15)

the SFN is a system frame number of a radio frame where a slot with an index of slot _ index is located, and the subframe _ index is an index of a subframe where a slot with an index of slot _ index is located.

Starting _ index can be further expressed as:

Starting_index＝SFN_Starting*M_subframe*M_slot+subframe_index_Starting*M_slot+slot_index_Starting (16)

the slot _ index _ Starting indicates an index of a slot in which a first unlicensed transmission resource is located, the subframe _ index _ Starting indicates an index of a subframe in which a slot with an index of slot _ index _ Starting is located, and the SFN _ Starting indicates a system frame number of a radio frame in which a slot with an index of slot _ index _ Starting is located.

By way of example and not limitation, when any one of the unlicensed transmission resources in the first time domain period includes one or more time units, and the time unit is a mini-slot, the TU _ index may be further represented as:

TU_index＝SFN*M_subframe*M_slot*M_mini-slot+subframe_index*M_slot*M_mini-slot+slot_index*M_mini-slot+mini-slot_index (17)

the subframe _ index is an index of a subframe where a mini-slot with an index of mini-slot _ index is located, and the slot _ index is an index of a slot where the mini-slot with the index of mini-slot _ index is located.

Starting _ index can be further expressed as:

Starting_index＝SFN_Starting*M_subframe*M_slot*M_mini-slot+subframe_index_Starting*M_slot*M_mini-slot+slot_index_Starting*M_mini-slot+mini-slot_index_Starting (18)

the mini-slot _ index _ Starting indicates an index of a mini-slot where a first unlicensed transmission resource is located, the slot _ index _ Starting indicates an index of a slot where the mini-slot with the index of mini-slot _ index _ Starting is located, and the subframe _ index _ Starting indicates an index of a subframe where the mini-slot with the index of mini-slot _ index _ Starting is located; SFN _ Starting indicates the system frame number of the radio frame where the mini slot with index mini-slot _ index _ Starting is located.

By way of example and not limitation, when any one of the unlicensed transmission resources in the first time domain period includes one or more time units, and the time unit is an OFDM symbol, the TU _ index may be further represented as:

TU_index＝SFN*M_subframe*M_slot*M_symbol+subframe_index*M_slot*M_symbol+slot_index*M_symbol+symbol_index (19)

the subframe _ index is an index of a subframe where an OFDM symbol with an index of symbol _ index is located; the slot _ index is an index of a slot in which an OFDM symbol of the index symbol _ index is located.

Starting _ index can be further expressed as:

Starting_index＝SFN_Starting*M_subframe*M_slot*M_symbol+subframe_index_Starting*M_slot*M_symbol+slot_index_Starting*M_symbol+symbol_index_Starting (20)

wherein symbol _ index _ Starting represents an index of an OFDM symbol where a first unlicensed transmission opportunity is located; slot _ index _ Starting represents the index of the time slot where the OFDM symbol with the index of symbol _ index _ Starting is located; subframe _ index _ Starting denotes an index of a subframe in which an OFDM symbol having an index of symbol _ index _ Starting is located, and SFN _ Starting denotes a system frame number of a radio frame in which an OFDM symbol having an index of symbol _ index _ Starting is located.

In combination with any of the relations (7) to (14) and any of the relations (15), (17) and (19), the local index of the time unit in which any one of the unlicensed transmission resources is located can be determined. Or it can be understood that, for a time unit determined by a local index, it is determined whether the time unit is a time unit in which an unlicensed transmission resource is located according to the method.

Taking any time unit contained in any unlicensed transmission resource in the first time domain period as an example of a mini-slot, a method for determining, by a terminal device, an index of a time unit in which the unlicensed transmission resource configured for the terminal device is located by the network device is described below.

The terminal device determines the index of the time unit where the unlicensed transmission resource is located according to the index of the time unit where the first unlicensed transmission resource is located, the first time domain period, the second time domain period, and the number k of the unlicensed transmission resources in the first time domain period.

Specifically, for example, the terminal device determines that one slot includes 7 mini slots, any one unlicensed transmission resource occupies 1 mini slot (i.e., T ═ 1), determines that each mini slot occupies 2 OFDM symbols, determines that a radio frame in which the first unlicensed transmission resource is located includes 10 sub frames, determines that a subframe in which the first unlicensed transmission resource is located includes 2 slots, determines that a first time domain period includes 7 mini slots, determines that a second time domain period includes 2 mini slots, and further determines that a system frame number of the radio frame in which the first unlicensed transmission resource is located is SFN _ starting, an index of the subframe in which the first unlicensed transmission resource is located is 0, that is, subframe _ index _ starting is 0, and an index of the slot in which the first unlicensed transmission resource is located is 0, namely, the slot _ index _ starting is 0, and the index of the mini slot in which the first unlicensed transmission resource is located is 0, that is, the mini-slot _ index _ starting is 0. The terminal device determines the number k of the unlicensed transmission resources included in the first time domain period according to the relation (1) as follows:

k＝ceil(7/2)＝4

the terminal device determines, according to the relation (14), that the index Starting _ index of the mini-slot in which the first unlicensed transmission resource is located in the global unlicensed transmission resource is (140 × SFN _ Starting +14 × 0+7 × 0+ 0).
