Description

Resource allocation method, device and system

technical field

The present application relates to the communication field, and in particular to a resource configuration method, device and system.

Background technique

In the grant-free transmission mechanism, when a terminal device has a data packet arriving, it does not need to request resources from the base station, but directly uses the pre-allocated authorization-free resources to send the data packet to the base station in a way that avoids authorization. The base station side Then, the authorization-free data sent by the terminal device is received on the pre-allocated resources by means of receiving technologies such as the blind detection side.

A key to license-free transmission is that the base station needs to pre-configure license-free resources for terminal devices to use at any time.

A method for the base station to configure authorization-free resources is: the base station first configures one or more authorization-free resources for the terminal device through high-level control signals, such as UE-specific RRC signaling (UE-Specific RRC Signaling) or broadcast (broadcast) signals, etc. Some or all of the resources and parameters, all the configured authorization-free resources cannot be used directly, but must be activated or reactivated by the underlying control signal (for example, Downlink Control Information (DCI)); For license-free resources in the activated (available) state, the base station can use the underlying control signal to deactivate the license-free resource after deactivation; the underlying control signal can also be used to configure or reconfigure some or all of the resources and parameters of the license-free resource .

Another method for the base station to configure license-free resources is: the base station first configures some or all resources and parameters of one or more license-free resources for the terminal device through high-level control signals, such as UE-Specific RRC Signaling or broadcast signals, and instructs The initial state of each configured license-free resource, for example, activated (available) state or deactivated (unavailable) state; for license-free resources in the deactivated state, the base station needs to use the underlying control signal (for example, DCI) to activate Or reactivation, and for the license-free resources in the activated state, the base station can use the underlying control signal to deactivate; the underlying control signal can also be used to configure or reconfigure some or all of the resources and parameters of the license-free resource.

As shown in Figure 1, in the above method, after the base station sends the underlying control signal to activate the unlicensed resource in time slot n-k1, the terminal device believes that the unlicensed resource is always available from time slot n until it is in time slot n+k2 A bottom layer control signal for deactivating the authorization-free resource sent by the base station is received. Similarly, the terminal device can consider that the authorization-free resource is available from the time slot n+k2+k3+k4+k1 only after receiving the activation instruction again in the time slot n+k2+k3+k4. Wherein, k1, k2, k3 and k4 are all integers greater than 1.

If the base station wants to make the unlicensed resources configured for the terminal equipment unavailable within a certain period of time (such as one or more consecutive time slots), or change some or all of the resources and parameter configurations of the unlicensed resources, the base station The underlying control signal must be issued first to deactivate the authorization-free resources, or to change some or all of the resource and parameter configurations of the authorization-free resources, and then send the underlying control signal again to reactivate the authorization-free resources after a specific period of time ends. Or restore resource and parameter configuration. When the duration of this specific time period is relatively short, occurs frequently, and has no regularity, this method will cause a large underlying control signal overhead.

For example, the wireless terminal device may also be a personal communication service (Personal Communication Service, PCS) phone, a cordless phone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA) and other equipment.

The authorization-free resources configured in the embodiment of this application generally include resources and parameters that can be used when configuring terminal devices to send data in an authorization-free manner. Specifically, resources include time domain resources (such as subframe numbers, time slot numbers, transmission Time interval (transmission time interval, TTI) index (index, etc.), frequency domain resources (such as subcarrier Index, resource block (resource block, RB) index, sub-band (sub-band) index, etc.), parameters include such as guide Frequency parameters, Modulation and Coding Scheme (MCS), power control parameters, frequency hopping (hopping) rules, maximum number of repeated transmissions (repetition), waveform (including cyclic prefix-orthogonal frequency division multiplexing (Cyclic Prefix OFDM) , CP-OFDM), discrete Fourier transform spread spectrum orthogonal frequency division multiplexing (Discrete Fourier Transformations spread OFDM, DFT-s-OFDM)) and so on.

The base station can configure one or more license-free resources for a terminal device at the same time. As shown in Figure 2, starting from time slot n, the base station configures four license-free resources for the terminal equipment in each time slot. The characteristics are as follows: the time-frequency resource of each license-free resource consists of one time slot and a subband in the frequency domain, each subband is composed of one or more subcarriers or resource blocks that are continuous or discontinuous in the frequency domain, and adjacent subbands can be continuous or discontinuous in the frequency domain; each license-free resource The repeated time interval in the time domain is 0 (or an integer greater than 0) time slots, and the repeated time intervals of different license-free resources in the time domain may be the same or different. In this example, a time slot can also be replaced by a subframe, a TTI, or a bundling of multiple time slots/subframes/TTIs, and a subband can also be replaced by a resource block, subcarrier, or multiple resource blocks / Subcarrier binding, etc.

If the base station wants to make the unlicensed resources configured for the terminal equipment unavailable within a certain period of time (such as one or more consecutive time slots), or change some or all of the resources and parameter configurations of the unlicensed resources, the base station The underlying control signal must be issued first to deactivate the authorization-free resources, or to change some or all of the resource and parameter configurations of the authorization-free resources, and then send the underlying control signal again to reactivate the authorization-free resources after a specific period of time ends. Or restore resource and parameter configuration. When the duration of this specific time period is relatively short, occurs frequently, and has no regularity, this method will cause a large underlying control signal overhead.

In view of the above problems, embodiments of the present application provide a resource configuration method, device, and system to solve the problem of high signaling overhead that occurs when bottom layer control signals configure authorization-free resources. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Fig. 3 shows a schematic flowchart of a resource configuration method provided by an embodiment of the present application, and the process may be specifically implemented by hardware, software programming, or a combination of software and hardware.

The base station can be configured to execute the process shown in Figure 3, and the functional modules used in the base station to implement the resource allocation scheme provided by the embodiment of the present invention can be specifically implemented by hardware, software programming, and a combination of software and hardware. The hardware can include One or more signal processing and/or application specific integrated circuits.

As shown in Figure 3, the process specifically includes the following processing procedures:

Step 30: the base station determines an effective time window configured for at least one authorization-free resource.

The base station may determine the length and start time of the valid time window configured for an unlicensed resource according to actual needs.

The base station configures the start time of the effective time window in the following ways:

1) The default way.

The base station configures the start time of the effective time window by default, for example, the base station defaults the start time of the effective time window to be the Xth time scheduling unit after the terminal device receives the configuration message carrying the effective time window indication information . For example, when the terminal device receives the configuration message at the kth scheduling time unit, the start time of the effective time window indicated by the configuration message is the k+X (X≥0) scheduling time unit. The terminal device also defaults that the start time of the effective time window is the Xth time scheduling unit after it receives the configuration message carrying the effective time window indication information. Optionally, X may be in a pre-set manner, that is, the base station and the terminal device agree and store the value in advance; it may also be determined by the base station and notified to the terminal device in a semi-static or dynamic manner.

2) A way to explicitly indicate the starting time of the effective time window.

For example, the base station notifies the terminal equipment through RRC signaling that after receiving the configuration message carrying the effective time window indication information in the kth scheduling time unit, the starting time of the indicated time window is the k+Xth (X≥ 0) scheduling time units. Optionally, the value of X may also be carried in a configuration message (such as DCI) used to configure authorization-free resources, and notify the terminal device in a dynamic manner. In an embodiment, the configuration message may carry information for indicating the start time and end time of the effective time window. In another embodiment, the configuration message may carry information for indicating the start time of the effective time window and the length of the effective time window.

It should be noted that, the scheduling time unit may be one or more consecutive subframes (subframe), slot (slot), mini-slot (mini-slot), symbol (symbol), transmission time interval (TTI) , frame (frame), etc.

Wherein, the at least one authorization-free resource configuration includes the following situations:

Situation 1: activating or reactivating the at least one authorization-free resource.

Situation 2: Deactivate the at least one authorization-free resource.

Situation 3: Configuring or reconfiguring some or all resources and parameters of the at least one authorization-free resource.

It should be noted that the effective time window of the authorization-free resource is used to indicate the effective time of the configuration for the authorization-free resource, that is, the configuration for the authorization-free resource is valid within the effective time window, and the configuration outside the effective time window time, the configuration for this authorization-free resource is invalid.

Correspondingly, corresponding to the above three situations, the effective time window configured for the authorization-free resource in the first case means that when the authorization-free resource is activated or reactivated, the authorization-free resource is only activated within the time indicated by the effective time window state, the terminal device can use the authorization-free resource to send authorization-free data, but in the deactivated state at other times, the terminal device cannot use the authorization-free resource to send authorization-free data.

Correspondingly, when the effective time window configured for the authorization-free resource in the above scenario 2 refers to deactivating the authorization-free resource, the authorization-free resource is only in the deactivated state within the time indicated by the effective time window, and the terminal device cannot use it. The authorization-free resource sends authorization-free data, but is activated at other times, and the terminal device can use the authorization-free resource to send authorization-free data.

Correspondingly, the effective time window for the configuration of authorization-free resources in the above-mentioned scenario 3 refers to the configuration or reconfiguration of some or all of the resources and parameters of the authorization-free resources. and parameters are only valid within the time indicated by the effective time window, the terminal device can use some or all of the resources and parameters of the authorization-free resource configured or reconfigured to send authorization-free data, while in other times, the terminal device cannot use the configured or reconfigured part or all of the resources and parameters of the authorization-free resource to send authorization-free data. Wherein, the time window is at least one continuous or discontinuous unit duration, and the unit duration is a time slot, subframe, frame, TTI, symbol, or mini-slot.

Schematically, FIG. 4a shows an implementation of a time window. At this time, the time window is at least one continuous time slot. Optionally, it may also be at least one continuous subframe or frame or TTI. This There is no limit to this in the application.

Schematically, FIG. 4b shows another implementation of the time window. At this time, the time window is at least one non-consecutive time slot. Optionally, it can also be at least one continuous subframe or frame or TTI , which is not limited in this application.

Step 31: The base station sends a configuration message to the terminal device, the configuration message is used to configure the at least one authorization-free resource, the configuration message carries effective time window indication information, and the effective time window indication information is used to indicate the The effective time window described above. The configuration indicated by the configuration message takes effect only within the effective time window indicated by the effective time window indication information carried in it, and is invalid at other times.

Optionally, the configuration message is a bottom layer control signal such as DCI or a high layer control signal such as an RRC message.

It is worth mentioning that the above-mentioned high-level control signal can be UE-Specific RRC Signaling for a specific terminal, or Group-based RRC Signaling for a specific group of terminals, or Cell-Specific RRC Signaling for all terminals in the cell, For example broadcast signals. The underlying control signal may be DCI for a specific terminal, or Group-based DCI or Common DCI for a specific group of terminals.

For the implementation of the message body of the configuration message, in a possible design, the configuration message includes a configuration field and a time window indication field corresponding to each authorization-free resource in the at least one authorization-free resource, wherein: the The configuration field carries the configuration information of the authorization-free resource, and the time window indication field carries the effective time window indication information.

The configuration domain corresponding to the authorization-free resource is used for:

(1) activate license-free resources, or reactivate license-free resources; or

(2) Deactivate license-free resources; or

(3) Configure or reconfigure part or all of the resources and parameters of the authorization-free resources, etc., this field consists of M bits, M≥1.

Specifically, when the configuration domain is used to realize the function of activating or reactivating authorization-free resources, the configuration domain at this time has the following two possible implementation methods:

In a possible implementation manner: the configuration field includes at least an indication field for indicating the state of the authorization-free resource, the indication field is composed of at least 1 bit, and a certain bit combination of the indication field indicates that the authorization-free resource is in an activated state, Other bit combinations in the indication field indicate that the authorization-free resource is in a deactivated state. For example, when the indication field consists of 1 bit, 1 represents activation and 0 represents deactivation; when the terminal receives the indication field of the status of the authorization-free resource contained in the configuration field as 1, it considers that the authorization-free resource is activated or reactivated ; When the terminal receives that the authorization-free resource status indication field contained in the configuration field is 0, it considers that the authorization-free resource is deactivated.

In another possible implementation mode: the function of the configuration field is implemented by other fields using a specific bit combination. For example, when the bit combination of the power control indication field of the uplink physical shared channel is all 0, it means that the license-free resource is activated. When the bit combination of the indication field indicating the coding and modulation scheme is all 0, it indicates that the license-free resource is deactivated. In another embodiment, when the bit combination of the power control indication field of the uplink physical shared channel is all 0, it means that the license-free resource is activated, and when the bit combination of the power control indication field of the physical uplink physical shared channel is all 1, it means that the license-free resource is activated. Activated.

When a configuration message is used to configure or reconfigure some or all resources and/parameters of an unlicensed resource, the configuration field of the configuration message may carry information indicating the unlicensed resource, for example, time domain resource information, frequency domain Resource information, time-frequency resource information, pilot information, MCS, power control parameters, frequency hopping rules, maximum number of repetitions, waveform (for example, CP-OFDM or DFT-s-OFDM), etc. Within the effective time window indicated by the effective time window indication field of the configuration message, the terminal device communicates using the authorization-free resources indicated by the configuration field in the configuration message.

Specifically, when the configuration domain is used to implement the function of configuring or reconfiguring some or all resources and parameters of an authorization-free resource, the configuration domain may include one or more indication domains as follows:

Time domain resource indication field, frequency domain resource indication field, pilot parameter indication field, coding and modulation scheme indication field, power control parameter indication field, frequency hopping rule indication field, maximum number of repeated transmissions, waveform parameter indication field, etc.

Time window indication field: used to inform the terminal device that the configuration for the authorization-free resource indicated by the configuration message is only valid within the indicated effective time window. This field consists of P bits, and P≥1.

When the base station configures N=1 authorization-free resources for the terminal equipment through high-level control signals, the configuration message format for configuring or reconfiguring the authorization-free resources can refer to FIG. 5a and FIG. 5b.

When the base station configures N>1 authorization-free resources for the terminal equipment through high-level control signals, the configuration message format for configuring or reconfiguring the authorization-free resources can refer to Figure 5c, Figure 5d and Figure 5e.

In this embodiment, when the base station configures N>1 authorization-free resources for the terminal device through high-level control signals, and there are N time window indication fields in the configuration message, for a certain authorization-free resource, the terminal device The position of the configuration domain of the authorization-free resource in the N configuration domains, and the position of the time window indication domain of the authorization-free resource in the N time window indication domains are used to determine the configuration domain for the authorization-free resource, and the Effective time window indication domain corresponding to authorization-free resources.

When the base station configures N>1 authorization-free resources for the terminal equipment through high-level control signals, and there is only one time window indication field in the configuration message, refer to Figure 5f and Figure 5g, indicating that the time window indication field corresponds to all N (N≥1) authorization-free resources, that is, the time window indication field is valid for the configuration of all N authorization-free resources; further, if there is only one configuration field in the configuration message, it means that the configuration indicated by the configuration field is applicable to all N license-free resources.

It should be noted that the positions of the time window indication field of the authorization-free resource and the configuration field in the configuration message may be interchanged.

Regarding the implementation of the message body of the configuration message, in another possible design, the configuration message includes, in addition to the configuration field and the time window indication field corresponding to the authorization-free resource, each of the at least one authorization-free resource The authorization-free resource identification domain corresponding to the authorization-free resource.

Authorization-free resource identification field: used to identify the authorization-free resource targeted by the configuration indicated by the configuration field. The authorization-free resource identification field consists of K (K≥0) bits, and can be used to identify up to 2K authorization-free resources.

When the base station configures N (N≥1) authorization-free resources for the terminal through high-level control signals, the configuration message format for configuring or reconfiguring the authorization-free resources can refer to FIG. 6a and FIG. 6b.

It should be noted that the positions of the identification field of the authorization-free resource, the time window indication field, and the configuration field in the configuration message may be interchanged. In this design, after receiving the configuration message, the terminal device can determine the authorization-free resource configuration field and the authorization-free resource corresponding to the time window indication field according to the authorization-free resource identification field.

Further, assuming that the time window indication field consists of P bits, the implementation method of the time window indication field in the above embodiment is given below.

Optionally, the time window indication field is set to a default value, indicating that no effective time limit is set for the configuration of the grant-free resource, that is, after the configuration message configures the grant-free resource, the terminal device thinks that the configuration indicated by the configuration message comes after It is valid until the configuration message for configuring the authorization-free resource is received again; the default value can be one or more of 2 ^P bit combinations, for example, all 0 bits or all 1 bits.

Optionally, when the time window indicated by the time window indication field is one or more consecutive time slots or subframes or frames or TTI or symbols or mini slots, a bit combination is used to indicate a specific number of consecutive time slots Or subframe or frame or TTI, for example, when P=2, the format of the time window indication field can refer to Table 1.

Table 1

Optionally, when the time window indicated by the time window indication field is one or more non-consecutive time slots or subframes or frames or TTIs or symbols or mini slots, a bit combination is used to indicate a specific number of non-consecutive time windows. Slot or subframe or frame or TTI, for example, when P=2, the format of the time window indication field can refer to Table 2.

Table 2

It should be noted that the contents of the above Table 1 and Table 2, and the format of the time window indication field may be pre-defined at the base station and terminal equipment side.

In a possible implementation manner, the above time window indication field may reuse an existing indication field for implementing other functions, such as an indication field for indicating a bundling (Bundle) granularity or aggregation (Aggregation) granularity or repeated transmission times. The granularity here refers to the number of subframes, timeslots, TTIs, symbols, etc. that are bundled or aggregated in time.

In an embodiment in which the function of the time window indication field is realized by reusing an existing indication field for implementing other functions, the configuration message may be DCI. When the DCI is used to configure authorization-free resources, the time window indication field implements the function of the time window indication field in this application; when the DCI is used for regular scheduling, the time window indication field is used to implement other functions.

Specifically, when the configuration message is DCI, the scrambling of the cyclic redundancy check (CyclicRedundancy Check, CRC) part of the configuration message may be performed in the following manner:

Way 1: Scrambling using a Cell Radio Network Temporary Identity (C-RNTI), such as DCI for a specific terminal device. In this way, a specific functional domain is set in the DCI to indicate to the terminal device whether the DCI is used for regular scheduling (such as uplink transmission based on request scheduling), or for configuring authorization-free resources as described in the embodiments of this application , for example, the specific function field consists of 1 bit, which means that the DCI is used for regular scheduling when it is 0, and that the DCI is used for configuring authorization-free resources when it is 1; or, when some fields in the DCI are preset When the value (such as all 0, or all 1, etc.) indicates that the DCI is used to configure license-free resources, otherwise it is used for regular scheduling. Some of the fields described here can be fields used to indicate modulation and coding schemes or other fields .

Method 2: use group cell radio network temporary identifier (Group C-RNTI, G-C-RNTI) for scrambling, such as Group-based DCI or Common DCI for a specific group of terminal devices. In this way, a specific functional domain is set in the DCI to indicate to the terminal device whether the DCI is used for regular scheduling (such as uplink transmission based on request scheduling), or for configuring authorization-free resources as described in the embodiments of this application , for example, the specific function field consists of 1 bit, which means that the DCI is used for regular scheduling when it is 0, and that the DCI is used for configuring or reconfiguring authorization-free resources when it is 1; or, when some fields in the DCI are set to When the value is preset (such as all 0, or all 1, etc.), it means that the DCI is used to configure authorization-free resources, otherwise it is used for regular scheduling. Some of the fields described here can be used to indicate the modulation and coding scheme. or other domains.

Method 3: Use the radio network temporary identity (Radio Network Temporary Identity, RNTI) predefined for authorization-free transmission, such as the scrambling of the radio network temporary identity (Grant-Free C-RNTI, GF-C-RNTI) defined as the authorization-free cell, At this time, for the DCI of a specific terminal device, in this way, after the terminal device uses the GF-C-RNTI to successfully descramble the DCI, it considers that the DCI is used to configure authorization-free resources.

Method 4: Use the wireless network temporary identifier pre-defined for authorization-free transmission, such as scrambling with the wireless network temporary identifier (Group GF-C-RNTI, G-GF-C-RNTI) defined as the authorization-free group cell. The group-based DCI or common DCI of a specific group of terminal devices. In this mode, after the terminal device uses G-GF-C-RNTI to successfully descramble the DCI, it considers that the DCI is used to configure authorization-free resources.

It should be noted that the DCI scrambling methods in methods 1 and 3 are aimed at a specific terminal device, while the DCI scrambling methods in methods 2 and 4 are aimed at a group of terminal devices and are applicable to the group of terminal devices each terminal device.

Regarding the above resource configuration method, FIG. 7 shows a flow chart of a method for a base station to configure authorization-free resources using DCI, specifically including the following process:

Step 70: The base station configures N (N≥1) authorization-free resources for the terminal equipment by using the RRC message.

Assuming N=4, the corresponding four license-free resources are the first license-free resource corresponding to time slot 1 and sub-band 2, the second license-free resource corresponding to time slot 2 and sub-band 3, and the second license-free resource corresponding to time slot 3 and sub-band 3. The third license-free resource corresponding to subband 1, and the fourth license-free resource corresponding to subband 4 of time slot 4.

Step 71: The base station sends DCI carrying time window indication information to the terminal device.

The DCI is used to configure one or more of the N license-free resources configured by the RRC message, and the time window indication information carried is used to inform the terminal device of the time window when the configuration indicated by the DCI takes effect. The configuration indicated by the DCI may be any of the configurations mentioned in the foregoing embodiments.

Assume that the DCI carries one time window indication information, indicating that the effective time window is the time slot with the time slot number 1. The configuration indicated in the DCI takes effect only in time slot 1, and the DCI does not change the configuration indicated by the RRC message in other time slots or the configuration indicated by the previous configuration message (for example, it may be an RRC message or a DCI message) configuration.

Step 72: The terminal device sends a confirmation message to the base station.

It should be noted that after receiving the DCI carrying the effective time window indication information, the terminal device considers that within the time window indicated by the effective time window indication information, the received configuration priority of the first authorization-free resource is higher than If the terminal device receives any signal for configuring the first authorization-free resource, it considers that the first authorization-free resource is in the activated state within the time window indicated by the effective time window indication information.

In other embodiments, when configuring N (N≥1) license-free resources for the terminal equipment by using the RRC message, the base station simultaneously configures a time window in which each license-free resource is in an activated state or in a deactivated state.

Fig. 8 shows a schematic flowchart of a resource configuration method provided by an embodiment of the present application, and the process may be specifically implemented by hardware, software programming, or a combination of software and hardware.

Step 80: The terminal device receives a configuration message sent by the base station, the configuration message is used to configure at least one authorization-free resource, the configuration message carries effective time window indication information, and the effective time window indication information is used to indicate the effective time window.

Optionally, after receiving the configuration message sent by the base station, the terminal device feeds back confirmation information to the base station.

Step 81: The terminal device applies the configuration indicated by the configuration message within the effective time window.

Specifically, the terminal device determines the effective time window of the at least one authorization-free resource based on the configuration message; the terminal device uses the at least one authorization-free resource within the effective time window of the at least one authorization-free resource transfer data.

It should be noted that after the terminal device receives the configuration message carrying the effective time window indication information, the interpretation of the configuration message has the highest priority within the effective time window, that is, the terminal device receives the configuration message carrying the effective time window indication information. After the configuration message for configuring authorization-free resources, it is considered that within the time window indicated by the effective time window indication information, the received configuration priority of authorization-free resources is higher than that of the same authorization-free resource configuration received by the terminal device. Signals for resources, including high-level control signals.

For example, assuming that the configuration message received by the terminal device configures a specific authorization-free resource, if the configuration operation is activated, no matter whether the authorization-free resource is activated or deactivated before the terminal device receives the configuration message, the terminal device It is considered that the authorization-free resource is in the activated state within the time window indicated by the effective time window indication information carried in the configuration message.

If the configuration operation is deactivation, no matter whether the authorization-free resource is activated or deactivated before the terminal device receives the configuration message, the terminal considers that the resource is within the time window indicated by the effective time window indication information carried in the configuration message. License-free resources are in the deactivated state.

If the configuration operation is to configure or reconfigure some or all of the resources and parameters of the authorization-free resources, then regardless of whether the resources and parameters of the authorization-free resources are configured in the previous high-level signaling such as RRC signaling, the terminal in the configuration message Within the time window indicated by the carried effective time window indication information, configuration messages are used to configure these resources and parameters.

Specifically, the starting moment of the effective time window may be in the following manner:

1) The default way.

Assume that after the terminal device receives the configuration message carrying effective time window indication information at the kth scheduling time unit, it considers that the starting time of the indicated time window is the k+X (X≥0)th scheduling time unit. Optionally, X can adopt a pre-set method, that is, the base station and the terminal device agree and store the value in advance; it can also be determined by the base station and notified to the terminal device in a semi-static or dynamic manner,

2) A way to explicitly indicate the starting time of the effective time window.

Assume that after the terminal device receives the configuration message carrying effective time window indication information at the kth scheduling time unit, it considers that the starting time of the indicated time window is the k+X (X≥0)th scheduling time unit. Optionally, the base station notifies the terminal device in a semi-static manner through RRC signaling, or may carry the value of X in a configuration message for configuring the authorization-free resource, and notifies the terminal device in a dynamic manner.

It should be noted that, the scheduling time unit may be one or more consecutive subframes (subframe), slot (slot), mini-slot (mini-slot), symbol (symbol), transmission time interval (TTI) , frame (frame), etc.

To sum up, in the embodiment of the present application, the base station determines the effective time window of at least one authorization-free resource configuration; sends a configuration message to the terminal device, the configuration message is used to configure the at least one authorization-free resource, and the configuration message carries the effective time window Time window indication information, the effective time window indication information is used to indicate the effective time window, so that the terminal device uses the at least one authorization-free resource to transmit data based on the configuration message; this can avoid the prior art When configuring authorization-free resources in a specific period of time, the problem of high underlying control signal overhead occurs to optimize system performance.
